Colton City Council
February 1, 2022

It is considered best practice to review the budget on an ongoing basis in order to ensure the fiscal integrity of all City operations. The purpose of this report is to provide current summary information that will assist the City Council in the decision making process. This report includes projections to close the fiscal year for each City fund, as well as all recommended changes to the budget including previously approved Council actions through the date of this report as illustrated in the attached Actual and Projected Fund Balances Worksheet.

ISSUES/ANALYSIS
Staff began the mid-year process by first examining the prior fiscal year’s outcomes, then proceeding to evaluate revenue and expenditure performance in the first six months of current fiscal year, and finally staff has made certain assumptions about performance for the final six months of the fiscal year. Based on this analysis and an analysis of the potential economic impacts of further pandemic-related emergency orders, staff has conservatively estimated ending balances for fiscal year 2021-22.

GENERAL FUND
As of December 31, 2021, with 50% of the fiscal year complete, General Fund revenues are

38.0% received while expenditures are 52.5% spent (including encumbrances 58.8% spent).

Certain major General Fund revenues, such as property taxes, are primarily collected in the second, third and fourth quarters of the fiscal year and thus, at mid-year, will generally show less than 50% collected. Property tax in-lieu of VLF, which represents approximately 13% of estimated revenue, is collected in the third and fourth quarters, and thus has a significant lowering effect on the percentage received in the first half of the fiscal year. In addition, sales tax receipts through December reflect only four months collection due to the required accrual method of accounting.

REVENUES
Overall, based on current estimates, revenues are projected to increase by $4,838,013 over current budgeted revenues, which represents an increase of 10.7% over the current budget and

10.9% over the original budget projections, as illustrated in the table below. 3 Packet Pg. 235

CURRENT
BUDGET

ESTIMATED

TO CLOSE
The revenue increase is attributed to projected growth in many revenue categories but predominately in the sales taxes, property taxes, and property tax in lieu of VLF categories. The Fiscal Year 2021-22 budget was adopted before the final FY2020-21 sales tax receipts were known, so the City adopted a rather conservative sales tax budget given the projected impacts of the pandemic on the City’s unique sales tax base were still unknown. While stay-at-home orders negatively impacted some sales tax categories as anticipated, such as those from fuel and service stations, but other categories like RV and auto sales and building and construction soared unexpectedly. The composure of the City’s unique sales tax base, coupled with various federal and state assistance programs, resulted in growth in the City’s sales tax over pre-pandemic years.

The $3,073,000 increase in the sales tax category alone represents 63.5% of the revenue increases at mid-year. Additionally, the property tax category improved over the original adopted budget. The City of Colton topped San Bernardino County’s growth comparison chart with an 11.99% change in net taxable value over the prior fiscal year. Contributing factors to the increase in property tax revenue included several large commercial properties adding to the tax roll, including the new warehouse on S La Cadena Dr., the Pellissier Logistics Center, and the California University of Science and Medicine. Additionally, residential sales values for detached, single family residential homes continued to climb through the year, with average and median prices exceeding pre-pandemic levels.

General Fund Transfer
With the adoption of the FY2021-22 budget, the total GFT amount approved by City Council in accordance with Measure V was $10,500,000. The FY2021-22 mid-year budget proposes no change to the GFT. In accordance with the Flow of Funds Ordinance, the GFT is calculated using the prior years’ audited actual gross revenues less any restricted revenue, which was finalized with the presentation of the Annual Comprehensive Financial Report for the year ending June 30, 2021. Therefore, the recommended GFT represents a 17.5% transfer. 3 Packet Pg. 236
Staff Report to the Mayor and City Council
FY2021-22 Mid-Year Budget Review
February 1, 2022

The GFT Oversight Committee functions in an advisory capacity to the City Council of the City of Colton. It makes recommendations regarding the GFT amount from the Electric Utility Fund to the City’s General Fund. The GFT Committee had a regular meeting scheduled on January 24, 2022 to consider its mid-year recommendations to the City Council. The Committee did not have a quorum for the meeting and, due to timing and noticing requirements, staff was unable to schedule another meeting prior to this City Council meeting. Staff made themselves available to answer questions and educate the Committee Members about the distributed agenda materials in advance of the City Council meeting to ensure Committee Members were able to understand the material. Committee Members were encouraged to reach out to their Council Members and submit their public recommendations on the item to City Council individually.

EXPENDITURES
With respect to expenditures, a majority of costs are relatively straight-line in nature, i.e., there is a proportionate share spent each month. However, there are some operating costs, as well as capital expenditures, that do not follow this pattern. Because of these timing issues, year-to-date expenditure percentages by Department may vary, while the overall budget to actual percentage is right in line with expectations. Overall, General Fund expenditures are estimated to increase by a net amount of $667,180 to close the fiscal year over the current adopted budget. After including the requested mid-year amendments and netting certain one-time items, the FY2021-22 projected General Fund expenditure estimate to close is illustrated as follows.

General Fund expenditures are projected to increase by a net of $667,180. The increase factors in the following:
 A $288,842 increase in salaries and benefits based on the recommended mid-year authorized position list and newly adopted MOU implementation netted against salary savings for vacant positions through the first half of the fiscal year.  A $150,000 increase in Police Department Overtime netted against a $75,000 savings in Part-time salaries for unfilled positions.
 A $100,000 increase in reimbursable development agreements for development project environmental reviews.
 A $52,000 increase in Parks Division overtime, which was offset by a $151,308 salary savings resulting from vacant positions through the first half of the year.  A $40,000 increase in animal shelter services with Riverside County.  A $39,500 increase in fuel across General Fund departments (Police, $27,000; Fire, $10,000; Public Works, $2,500).
 A $28,638 increase in part-time salaries in Human Resources.  A $23,200 increase in professional services in the Fire Department for grant consulting, ambulance JPA formation feasibility, and standards of response coverage report services.  Additional requests include:, Inflationary increases for previously budgeted vehicle purchase, $13,500; Public notices requiring published noticing, $5,000; and other nominal increases/decreases to various line items totaling $1,500 across all departments. 3 Packet Pg. 237

The revenue and expenditure adjustments recommended herein are projected to result in the following fund balance outcome for the General Fund:

Total General Fund Balance as of June 30, 2021 $ 37,364,104 Pension Reserve Balance, June 30, 2021 19,820,872
OPEB Reserve Balance, June 30, 2021 7,793,103
Settlement Reserve Balance, June 30, 2021 1,300,000
Total Available General Fund Balance, June 30, 2021 $ 8,450,129 Projected Revenues for FY 2021-22 49,852,166
Projected Expenditures for FY 2021-22 51,291,896
FY 2020-21 Surplus/(Deficit) (1,439,730)
Estimated Fund Balance on June 30, 2022 $ 35,924,374
Available Fund Balance June 30, 2022 8,310,399
Pension Reserve Balance, June 30, 2022 19,820,872
OPEB Reserve Balance, June 30, 2022 7,793,103
These amendments result in a General Fund structural deficit of ($1,439,730), balanced with the use of reserves. The total General Fund reserve balance at June 30, 2022 is projected to be $35,924,374, of which $19,820,872 is committed for pension obligations and $7,793,103 is committed for OPEB obligations. The total available General Fund Reserve Balance at June 30, 2022 is estimated to be $8,310,399, or approximately 16.2% of proposed General Fund expenditures, meeting the City’s 15% reserve requirement.

Personnel Requests
Upon recommendation from the City Manager and the Finance Committee, included in the requested mid-year appropriations are the following personnel requests:
 Add one (1) Part-time Administrative Assistant to replace one (1) Full-time Administrative Assistant in the City Manager’s Office.
 Adjustment of the salary range for the Deputy City Clerk classification to reflect current market rate. This classification was found to be significantly out of market, despite recent negotiated MOU changes. This recommended adjustment will ensure the classification is paid at market.
 Add one (1) Full-time Accountant for department support in grant management and accounting. The City is managing significantly more grants that it has in the past, making it more critical to support grant management and reimbursement requests for grant expenditures. This position will ensure the City can continue to obtain federal awards and manage grants within the framework of the Uniform Guidance for Federal Grants.

 Add one (1) Full-time Office Specialist I/II in the Fire Department to assist with the Fire Prevention administrative duties and billing. This position is funded by the Fire Prevention revenues in the updated fee schedule adopted by City Council.  Add one (1) Full-time Assistant Planner in the Development Services Department. This new classification will assist with employee retention and bridge the disparity in required minimum qualifications between the Planning/Building Technician I/II classification and the Associate Planner classification. Staff will return to City Council to adopt a salary schedule and job description after due diligence is complete.  Reclassify one (1) Office Specialist I/II to an Administrative Analyst I/II in the Electric Division of the Public Works & Utility Services Department to better fit the operational needs of the utility and to address a working-out-of-class situation.

ENTERPRISE FUNDS
The City’s major enterprise funds, namely Electric, Water and Wastewater, are all recommended for adjustment at mid-year based on current operations and capital improvement expectations through the end of the fiscal year. It should be noted that each of these operations met or exceeded projected operating results for the prior fiscal year.

Electric
The Electric Department is projecting overall revenues for fiscal year 2021-22 to decrease by $194,850 over the current adopted budget. Of the decreased revenues, $300,000 is attributed to a decrease in late charges and penalties and interest. Also expected to decrease over original projections were pooled interest revenue ($275,000) and development fees ($200,000) which were offset by a $550,000 increase in restricted revenue from consigned emissions allowances.

All revenue offsets are considered one-time in nature. Year-end expenditure projections anticipate an increase of $1,888,863 in expenditures over the current budget resulting primarily from a $1,816,413 increase in purchased power for natural gas and firm power.

Based upon current estimates and after factoring out the current net investment in capital assets and required reserve for debt service, the Electric Fund is expected to end the year with an approximate available net position of $16,592,151.

Staff Report to the Mayor and City Council
FY2021-22 Mid-Year Budget Review
February 1, 2022

Water
The Water Fund revenue projections reflect a net decrease of $78,774 over the current budget, which is mostly attributed to an $80,000 decrease in anticipated interest income offset by some other minor adjustments. Water Fund expenditures through the end of fiscal year 2021-22 are expected to decrease complementarily by $212,837 over the current budget. The decrease in expenditures is mostly attributed to a $229,837 salary savings from vacant positions netted against minor operational adjustments based on year-to-date actuals.

Wastewater
The latest revenue projections in the Wastewater Fund reflect a $96,023 increase over the current budget, attributed to a $172,523 increase in revenue from Grant Terrace sewer charges offset by a $46,500 decrease in interest income and a $30,000 decrease in late charges. Expenditures are also projected to increase over the current budget by $277,383, which is associated with salary increases from previously negotiated MOU changes, a $49,365 increase in overtime, and nominal other adjustments in utilities operations expenses based on year-to-date actuals.

ALL OTHER FUNDS
All revenue or expenditure adjustments recommended for any other funds (not previously mentioned earlier in this report) are considered routine in nature and reflected on the Actual and Projected Fund Balances worksheet attached to this report.

All projections have been updated for balances as reflected in the ACFR for the year ended June 30, 2021, as well as any other known items through the date of this report.

FINANCE COMMITTEE
The Finance Committee met on January 19, 2022 to review the City Manager’s recommended FY2021-22 mid-year budget. The Committee reviewed the proposed General Fund adjustments, personnel requests, General Fund Transfer (GFT) analysis, available fund balance analysis, and a five-year financial forecast for the General Fund. The Committee was in agreement with the mid-year recommendations presented by staff.

Additionally, based on the five-year projections for the General Fund, the Finance Committee recommended that staff bring forward a one percent (1%) Transactions and Use Tax for separate City Council consideration for the November 2022 ballot.

FISCAL IMPACTS
Adoption of Resolution R-10-22, CUA-01-21, and CHA-01-21 will amend the budget to reflect the most current estimates to close the fiscal year. In summary, the respective major fund types are expected to end with the following projected available balances:
 General Fund $ 8,310,399

STAFF REPORT
DATE: FEBRUARY 1, 2022
TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS
FROM: BILL SMITH, CITY MANAGER
PREPARED BY: BRIAN DICKINSON, PUBLIC WORKS AND UTILITY SERVICES

DIRECTOR
SUBJECT: ADOPTION OF CEQA-IS/MND FOR BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT.

RECOMMENDED ACTION
Staff recommends that the City Council take the following action:

It is recommended that the City Council adopt the California Environmental Quality Act (CEQA) Initial Study/Mitigated Negative Declaration (IS/MND) for the Barton Bridge over UPRR Track Removal and Road Construction Project.

BACKGROUND
Barton Road Bridge is located between Interstate 215 and La Cadena Drive, and extends over the Union Pacific (UP) railroad right of way. Barton Road bridge is currently rated as “structurally deficient” by the California Department of Transportation (Caltrans) and in need of repairs or replacement. Since the tracks were abandoned and removed by Union Pacific Railroad Company (UPRR), it will be cost effective to remove the bridge and construct a new road. The new road will be a two lane road with bike lane and sidewalk. A joint approach to the Barton Road Bridge Replacement Project (“Project”) has been undertaken by the City of Colton and City of Grand Terrace since the physical location of the Barton Road Bridge lies within the city boundaries of both cities.

On July 12, 2017, the City received the Administering Agency - State Agreement and the Program Supplement Agreement (Preliminary Engineering Phase - Environmental and Design) for the Barton Road Bridge Removal and Road Construction Project. The Administering Agency-State Agreement identifies the State and the Local Agency’s role and responsibility on the Project. The Program Supplement Agreement identifies the funding commitment and 7 Packet Pg. 362

CEQA - Barton Road Bridge Removal and Road Construction Project February 1, 2022

responsibility for the State and Local Agency. The Project will receive a total of $3,153,863 from Federal Fund - Highway Bridge Program (HBP). The local match required is $408,617 (11.47%) and will be shared equally by Colton and Grand Terrace. A Cooperative Agreement for the Project between the City of Colton and the City of Grand Terrace was approved by the City Council on September 5, 2017. The Cooperative Agreement identifies the funding commitment, and the tasks, role and responsibilities for the development and construction of the Project. The City of Colton is the Lead Agency for the Project.

ISSUES/ANALYSIS
On April 16, 2019, the City awarded a contract to CNS Engineers, Inc. for the preparation of environmental documents, engineering design and right of way support for the Barton Road Bridge Removal and Road Construction Project. The project plan prepared by CNS Engineers, Inc. is attached as Exhibit A and environmental technical studies are completed already. The National Environmental Protection Agency (NEPA) Categorical Exclusions documents were approved by Caltrans on 8/18/2021 (Exhibit B).

The Project’s California Environmental Quality Act (CEQA) Initial Study/Mitigated Negative Declaration (IS/MND) document (Exhibit C) was circulated on July 19, 2021 and closed for review on August 18, 2021 for the 30-day public review process. Only one comment letter was received on the process. The letter was sent by Elsinore Valley Municipal Water District (EVMWD) due to their concern on their existing water lines and well site near the vicinity of bridge removal and road construction project. City and EVMWD staff, and City design and environmental consultants met on 11/4/21 to discuss and resolve the water district comments.

The letter and responses to the comments was incorporated as Appendix H of the IS/MND documents.

The City needs to adopt the IS/MND to complete the environmental phase for the Barton Road Bridge Removal and Road Construction Project. The project will proceed to the right of way phase after the completion of the environmental phase. Construction of the project is estimated to be completed by December 2024.

FISCAL IMPACTS
No fiscal impact for this action.

ENVIRONMENTAL IMPACTS
Adoption of IS/MND will complete the California Environmental Quality Act (CEQA) process for this project. National Environmental Protection Agency (NEPA) process for this Project was completed on 8/18/2021.

Project Description
The Cities of Colton and Grand Terrace, in the County of San Bernardino, propose to replace the existing 2-lane bridge (BR No. 54C0379) over the abandoned alignment of the Union Pacific RR with a two-lane at-grade asphalt roadway. Work includes construction of ADA curb ramps, sidewalk and Class II bike land on the north side of the bridge, driveway approaches, remove retaining walls, cut and fill and utility relocation.

The project is in need because the bridge is structurally deficient and does not account for seismic loading. The purpose of the project is to provide safe connectivity between La Cadena and the Barton Rd/I-215 IC. The project will require approx. 12 temporary construction easements and 1 partial acquisition.

Air Quality
AQ-1: Prior to the commencement of any construction activities, the construction contractor shall submit a Construction Emission Control Plan for review and approval to the City of Colton Department of Public Works, which shall be implemented during construction. The Construction Emissions Control Plan shall comply with federal, State, and local regulations as specified in the measures below:
• The contractor shall adhere to the Caltrans Standard Specifications for Construction, Sections 14.9-01, 14.9-02, 14.9-03, 18-1.02C, and 18-1.03 (or Greenbook equivalent specifications). Section 14-9-02 specifically requires compliance by the contractor with all applicable laws and regulations related to air quality, including air pollution control district and air quality management district regulations and local ordinances.
• Water or a dust palliative shall be applied to the site and equipment as often as necessary to control fugitive dust emissions. Fugitive emissions generally must meet a “no visible dust” criterion either at the point of emissions or at the right-of-way line depending on local regulations in compliance with the SCAQMD Rule 403 (Fugitive Dust).
• Soil binder shall be spread on any unpaved roads used for construction purposes, and on all project construction parking areas (providing an estimated 50 percent reduction of fugitive emissions) in compliance with the SCAQMD Rule 403 (Fugitive Dust).
• Trucks shall be washed as they leave the right-of-way as necessary to control fugitive dust emissions in compliance with the SCAQMD Rule 403 (Fugitive Dust).

• Construction equipment and vehicles shall be properly tuned and maintained. All construction equipment shall use low-sulfur fuel as required by California Code of Regulations (CCR) Title 17, Section 93114.
• A dust control plan shall be developed documenting sprinkling, temporary paving, speed limits, and timely revegetation of disturbed slopes as needed to minimize construction impacts to existing communities in compliance with the SCAQMD Rule 403 (Fugitive Dust).
• Equipment and material storage sites shall be located as far away from residential uses as practicable. Construction areas shall be kept clean and orderly in compliance with the SCAQMD Rule 402 (Nuisance).
• Within 500 feet of sensitive air receptors, construction activities involving the extended idling of diesel equipment or vehicles will be prohibited to the extent feasible [as required by CCR Title 13, Section 2485(c)]. • Track-out reduction measures shall be used, such as gravel pads at project access points to minimize dust and mud deposits on roads affected by construction traffic, in accordance with the State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4).
• All transported loads of soils and wet materials shall be covered before transport, or adequate freeboard (space from the top of the material to the top of the truck) shall be provided to minimize emission of dust during transportation in compliance with the SCAQMD Rule 403.
• Dust and mud that are deposited on paved, public roads due to construction activity and traffic shall be promptly and regularly removed to reduce PM emissions [State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4)].
• To the extent feasible, construction traffic shall be scheduled and routed to reduce congestion and related air quality impacts caused by idling vehicles along local roads during peak travel times (consistent with the traffic control plan approved by the City of Colton Traffic Engineer).

Mulch shall be installed or vegetation planted as soon as practical after grading to reduce windblown PM in the area. Note that certain methods of mulch placement, such as straw blowing, may themselves cause dust and visible emission issues and may require controls such as dampened straw [Caltrans Standard Specifications for Construction, Sections 18.1-02C (Dust Control Binders) and 18-1.03 (Construction – Dust Palliatives) or Greenbook equivalent].

Biological Resources
BIO-1: Prior to construction, an approved bat biologist shall be retained by the Project proponent to conduct a bat assessment survey to determine the presence or absence of bat species that may occur within the Project limits. Should the presence of bat species be determined during this assessment, the following measures shall be implemented:
• Nighttime exit counts and acoustic surveys shall be performed by a qualified bat biologist at all structures and palm trees that may be subject to project-related impacts.

These surveys shall be performed during the recognized bat maternity season (April

1 through August 31, but preferably in June or July) and as far in advance of construction as possible in order to provide adequate time for mitigation planning. • Construction activities at structures housing maternity colonies shall be coordinated with an approved bat biologist and CDFW.
• If direct impacts to bat-roosting habitat are anticipated, humane evictions and exclusions of roosting bats shall be performed under the supervision of an approved bat biologist after August 31 in the fall (September or October) prior to any work activities that would result in direct impacts or direct mortality to roosting bats. This action shall be performed in coordination with the CDFW. To avoid potential mortality of flightless juvenile bats, evictions and exclusions of bats cannot be performed during the maternity season (April 1 through August 31). Winter months are also inappropriate for bat eviction because not all individuals in a roost will emerge on any given night. In addition, long-distance movements to other roost sites are more difficult during the winter when prey availability is scarce, resulting in high mortality rates of evicted bats.
• Alternative bat-roosting habitat structures shall be installed on the structures prior to the eviction/exclusion of bats from that structure. The design, numbers, and locations of these roost structures shall be determined in consultation with an approved bat biologist.
• If permanent, direct impacts to bat-roosting habitat are anticipated and a humane eviction/exclusion is performed, alternative permanent roosting habitat shall be provided to ensure no net loss of bat-roosting habitat. This action shall be coordinated with the CDFW, and locations of these roost structures shall be determined in consultation with an approved bat biologist to ensure that the installed habitat provides adequate mitigation for impacts.
• The loss of a night roost can negatively affect the use of a foraging area, and consequently may result in reduced fecundity in species that are already slow to reproduce. If night roosting is confirmed at any of the structures within the proposed Project area, the following measure to minimize potential impacts to night-roosting and foraging bats shall be implemented:
o At structures where night roosting is suspected or confirmed, work shall be limited to the daylight hours to the greatest extent feasible to avoid potential disruption of foraging. If night work cannot be avoided, night lighting shall be focused only on the area of direct work, airspace access to and from the roost features of the structure shall not be obstructed, and light spillover into the adjacent foraging areas shall be minimized to the greatest extent feasible.

CR-1: If buried cultural resources are encountered during Project Activities, it is Caltrans policy that work stop in that area until a qualified archaeologist can evaluate the nature and significance of the find.

CR-2: In the event that human remains are found, the county coroner shall be notified and ALL construction activities within 60 feet of the discovery shall stop. Pursuant to Public Resources Code Section 5097.98, if the remains are thought to be Native American, the coroner will notify the Native American Heritage Commission (NAHC) who will then notify the Most Likely Descendent (MLD). The person who discovered the remains will contact the District 8 Division of Environmental Planning; Andrew Walters, DEBC: (909)383-2647. Further provisions of PRC 5097.98 are to be followed as applicable.

CR-3: If deposits of prehistoric or historical archaeological materials are discovered during non-monitored Project activities, all work within 25 feet of the discovery shall be redirected and a qualified archaeologist contacted, if one is not present, to assess the situation, consult with agencies as appropriate, and make recommendations for the treatment of the discovery. The City of Colton and Grand Terrace shall also be notified.

Project personnel shall not collect or move any archaeological materials uncovered by construction activities.

Any adverse impacts to the finds shall be avoided by Project construction activities. If avoidance is not feasible, the archaeological deposits shall be evaluated to determine if they qualify as a historical resource or unique archaeological resource, or as historic property. If the deposits do not so qualify, avoidance is not necessary. If the deposits do so qualify, adverse impacts on the deposits shall be avoided, or such impacts shall be mitigated. Mitigation may consist of, but is not limited to, recovery and analysis of the archaeological deposit; recording the resource; preparing a report of findings; and accessioning recovered archaeological materials at an appropriate curation facility.

Educational public outreach may also be appropriate. Upon completion of the assessment, the archaeologist shall prepare a report documenting the methods and results, and provide recommendations for the treatment of the archaeological deposits discovered. The report shall be submitted to the City of Colton and City of Grand Terrace.

TCR-1: In the event that cultural resources are discovered during project activities, all work in the immediate vicinity of the find (within a 60-foot buffer) shall cease and a qualified archaeologist meeting Secretary of Interior standards shall be hired to assess the find. Work on the other portions of the project outside of the buffered area may continue during this assessment period. Additionally, the San Manuel Band of Mission Indians Cultural Resources Department (SMBMI) shall be contacted, as detailed within TCR-2, regarding any pre-contact and/or historic-era finds and be provided information after the archaeologist makes his/her initial assessment of the nature of the find, so as to provide Tribal input with regard to significance and treatment.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 1 1.0 INTRODUCTION AND PURPOSE

1.1 INTRODUCTION
Section 1.0 of this Initial Study (IS) describes the purpose, environmental authorization, the intended uses of the IS, documents incorporated by reference, and the processes and procedures governing the preparation of the environmental document. Pursuant to Section 15367 of the State of California Guidelines for Implementation of the California Environmental Quality Act (CEQA Guidelines), the City of Colton (City) is the Lead Agency under the California Environmental Quality Act (CEQA). The City has primary responsibility for compliance with CEQA and consideration of the Barton Road Bridge Removal and Road Construction Project (“Project” or “proposed Project”).

The Initial Study is organized as follows:

Section 1.0 Introduction and Purpose provides a discussion of the Initial Study’s purpose, focus, and legal requirements.

Section 2.0 Project Description provides a detailed description of the proposed Project.

Section 3.0 Environmental Checklist includes a checklist and accompanying analyses of the Project’s effect on the environment. For each environmental issue, the analysis identifies the level of Project’s environmental impact.

Section 4.0 References details the references cited throughout the document.

Appendices Includes the technical material prepared to support the analyses contained in the IS.

1.2 PURPOSE
CEQA requires that the proposed Project be reviewed to determine the environmental effects that would result if the Project were approved and implemented. The City is the Lead Agency and has the responsibility of preparing and adopting the associated environmental document prior to consideration of the approval of the proposed Project. The City has the authority to make decisions regarding discretionary actions relating to implementation of the proposed Project.

This IS has been prepared in accordance with the relevant provisions of CEQA (California Public Resources Code Section 21000 et seq.); the CEQA Guidelines,1 and the rules, regulations, and procedures for implementing CEQA as adopted by the City. The objective of the Initial Study is to inform City decisionmakers, representatives of other affected/responsible agencies, the public, and interested parties of the potential environmental consequences of the Project.

As established in CEQA Guidelines Section 15063(c), the purposes of an IS are to:
• Provide the Lead Agency (City of Colton) with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration (ND), or Mitigated Negative Declaration (MND);
• Enable an applicant or Lead Agency to modify a project, mitigating adverse impacts before an EIR is prepared, thereby enabling the project to qualify for an ND or MND;

1 California Code of Regulations, Title 14, Chapter 3, Sections 15000 through 15387.

Packet Pg. 395 Attachment: Exhibit C_Part1 - Barton Road Bridge Removal ISMND (3479 : CEQA - Barton Road Bridge Removal and Road Construction

INITIAL STUDY/MITIGATED NEGATIVE DECLARATION

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 2 • Assist in the preparation of an EIR, if one is required; • Facilitate environmental assessment early in the design of a project; • Provide a factual basis for finding in an ND or MND that a project will not have a significant effect on the environment;
• Eliminate unnecessary EIRs; and
• Determine whether a previously prepared EIR could be used with the project.

1.3 INTENDED USE OF THIS INITIAL STUDY
The City formally initiated the environmental process for the proposed Project with the preparation of this Initial Study. The IS screens out those impacts that would be less than significant and do not warrant mitigation, while identifying those issues that require further mitigation to reduce impacts to a less than significant level. As identified in the following analyses, Project impacts related to various environmental issues either do not occur, are less than significant (when measured against established significance thresholds), or have been rendered less than significant through implementation of mitigation measures.

Based on these analytical conclusions, this IS supports adoption of an MND for the proposed Project.

CEQA2 permits the incorporation by reference of all or portions of other documents that are generally available to the public. The IS has been prepared utilizing information from City planning and environmental documents, technical studies specifically prepared for the Project, and other publicly available data. The documents utilized in the IS are identified in Section 4.0 and are hereby incorporated by reference. These documents are available for review at the City of Colton, Public Works Department.

1.4 PUBLIC REVIEW OF THE INITIAL STUDY
The IS and a Notice of Intent (NOI) to adopt an MND will be distributed to responsible and trustee agencies, other affected agencies, and other parties for a 20-day public review period. Written comments regarding this Initial Study should be addressed to:

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 3 2.0 PROJECT DESCRIPTION

2.1 PROJECT LOCATION
The Project site is located on Barton Road over the abandoned Union Pacific Rail Road (UPRR) tracks and Southern California Edison (SCE) easement between Terrace Avenue and Grand Terrace Road straddling the boundary of the Cities of Colton and Grand Terrace. Surrounding uses in the vicinity of the Project site include industrial businesses, surface parking lots, the inactive UPRR corridor and SCE easement to the north; Barton Road and single-family residential units to the east; industrial/commercial businesses, surface parking lots, undeveloped land, and the inactive UPRR corridor and SCE easement to the south; and, Barton Road, surface parking lots, and Terrace Avenue to the west. Figure 1: Regional Location and Figure 2: Project Location shows the location of the proposed Project on a regional and local basis.

2.2 LAND USE
The Project site is located on Barton Road over the inactive UPRR corridor and active SCE easement. The Project site itself does not have a land use designation nor a zoning designation. Table 2.2.A summarizes surrounding land uses, General Plan designations and zoning designations.

2.3 PROJECT DESCRIPTION
The Project is being proposed to provide a safe connectivity between La Cadena and the Barton Road/Interstate-215 (I-215) interchange and to facilitate efficient access between the Cities of Colton and Grand Terrace. Barton Road Bridge was originally built in 1936 as a two-lane bridge over the UPRR railroad tracks (one lane in each direction). The bridge is structurally unsound and the 25-foot wide bridge deck does not provide adequate pedestrian or bicycle access in accordance with City standards. A review of the existing bridge’s plans shows the design does not account for seismic loading, which is now required in the state of California. The Bridge Inspection Report shows a low sufficiently rating of 58.8 due to low load rating and a roadway geometry that does not meet current American Association of State Highway and Transportation Officials standards. The railroad tracks below the Barton Road Bridge have been abandoned and removed; as such, there is no longer the need to span the railroad tracks with a bridge.

INITIAL STUDY/MITIGATED NEGATIVE DECLARATION

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 4 The Cities of Colton (CEQA Lead Agency) and Grand Terrace (Responsible Agency) in cooperation with the California Department of Transportation (Caltrans) proposes to remove the bridge (State Bridge No. 54C0379), fill the area over the railroad corridor, and replace the bridge with a two-lane at grade asphalt roadway to connect to the existing roadway to the east and west of the bridge. There is also the need to provide continuous pedestrian and bicycle access along this stretch of Barton Road through implementation of sidewalks and Class II bicycle lanes to meet the requirements of both the Cities of Colton and Grand Terrace.

Improvements to Barton Road will begin at the east side of Terrace Avenue intersection in the City of Colton and extend to approximately 100 feet west of the intersection of Grand Terrace Avenue in the City of Grand Terrace. The curb-to-curb roadway width of 44 feet widens to approximately 70 feet of west Grand Terrace Avenue to tie into the improvements that have been made to the Barton Road/I-215 interchange. The total length of the roadway improvements is approximately 1,100 feet. The roadway will accommodate a 6-foot wide sidewalk on the north and south side of Barton Road, an 8-foot wide striped Class II bicycle lane on each side of the roadway and 14-foot wide travel lanes. Land configurations transition to join existing improvements west of Grand Terrace Avenue. Improvements associated with the proposed Project include the following:
• Demolition and removal of the existing bridge, abutments, and retaining walls on Barton Road. • Remove and reconstruct the drainage outlet west of Grand Terrace Avenue; construct a drainage culvert across Barton Road in the vicinity of the abandoned tracks. • Relocate the Riverside Highland Water Company line, City waterline, fiber optic cables, and gas line in the existing bridge and roadway; relocate overhead telephone lines spanning along the north side of Barton Road.
• Cut of approximately 5,800 cubic yards and fill of approximately 4,300 cubic yards to bring the bridge area to grade.
• Construct asphalt roadway, remove the vertical crest curve improving stopping sight distance consistent with the Cities standards of Barton Road’s roadway classification. • Construct curb ramps at the intersection of Barton Road and Terrace Avenue to American Disabilities Act standards. (Note: improvements associated with planned developments in the project area will be required to match the profile of the planned Barton Road improvements.) • Construct 6-foot wide sidewalk, and 8-foot wide Class II bike lane on north and south side of Barton Road within the Project limits.
• Construct driveway approaches joining existing driveways to City of Colton and Grand Terrace standards.
• Remove a retaining wall along the north side of Baron Road right of way in front of (current) Lineage Logistics building.
• Identify and provide a construction staging area in the vicinity of the improvements. • Close Barton Road between Terrace Avenue and Grand Terrace Avenue during construction and provide a detour for traffic. The detour will route traffic around the construction zone on Barton Road via S. Terrace Avenue, De Berry Street, and S. La Crosse Avenue.

INITIAL STUDY/MITIGATED NEGATIVE DECLARATION

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 5 The proposed Project will require approximately 0.60 acre of temporary construction easements and slope easements. The majority of improvements with the exception of grading of driveways to match the lowered street elevation will be contained to the Cities’ existing right-of-way. Right-of-way acquisitions will occur on the following parcels: APNs 1167 121 06; 1167 121 07; 0275 223 24; 0275 223 58; and, 0275 223 16. Approximately 3,800 square feet will be acquired to increase the right of way at the location of the existing bridge to 50 feet in each direction plus approximately 50 square feet of permanent right of way acquisition will be needed in front of Assessors’ Parcel Number (APN) 0275-223-16 (this parcel is located within the City of Grand Terrace). Figure 3: Project Design shows the design of the proposed Project along Barton Road.

2.4 METHODOLOGY
The analysis in this IS/MND provides an environmental review of the Project pursuant to CEQA. The details of the proposed Project and associated actions have been characterized in this section and are also addressed in detail throughout Section 3.0 of this IS/MND. If the Project is approved, the Project would be allowed without further discretionary approval, so long as the improvements comply with the City’s regulations and project-specific mitigation measures and Conditions of Approval.

2.5 REQUIRED PERMITS AND APPROVALS
The City is expected to use this IS/MND in consideration of the proposed Project and associated actions.

These actions may include, but are not limited to, the following:

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 16 EVALUATION OF ENVIRONMENTAL IMPACTS

1. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question.

A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).

2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.

3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect may be significant. If there are one or more “Potentially Significant Impact” entries when the determination is made, an Environmental Impact Report (EIR) is required.

4. “Negative Declaration: Less Than Significant With Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than Significant Impact.” The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from “Earlier Analyses,” as described in (5) below, may be cross-referenced).

5. Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D).

In this case, a brief discussion should identify the following:
a. Earlier Analysis Used. Identify and state where they are available for review. b. Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis.
c. Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project.

6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated.

7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion.

8. This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project’s environmental effects in whatever format is selected.

9. The explanation of each issue should identify:
a. The significance criteria or threshold, if any, used to evaluate each question; and b. The mitigation measure identified, if any, to reduce the impact to less than significance.

a. Would the project have a substantial adverse effect on a scenic vista? No Impact. Scenic and other important visual features typically include parks, natural open space and topographic features, and native flora. Views of the San Bernardino and San Gabriel Mountains form a scenic backdrop for the northern portion of the City of Colton. These vistas are shared amongst all of the cities surrounding/bordering the City of Colton and Grand Terrace. The only scenic resource within the City of Colton is the Santa Ana River and its surrounding natural areas. Views of this natural feature are accessible from the surrounding area as well as through the recreational use of the San Ana River area.

The Project site is located on Barton Road, straddling the cities of Colton and Grand Terrace boundary, in an urban area. There are no scenic vistas or important visual features within the boundary of the Project site. Motorists traveling westbound on Barton Road have views of the La Loma Hills while motorists traveling eastbound on Barton Road have semi-unobstructed views of Blue Mountain. The San Bernardino and San Gabriel Mountains and the Santa Ana River are not visible to motorists traveling through the Project site on Barton Road. The proposed Project includes the removal of an existing bridge crossing over the abandoned UPRR corridor, filling of the area and development of a new portion of Barton Road in place of the old bridge. No tall structures would be developed with the proposed Project resulting in views of the local hills being obstructed to motorists. The closest single-family residential units to the proposed Project are located along Grand Terrace Road and face predominantly to the east, away from the Project site. As such, the proposed Project would not obstruct views of the La Loma Hills and Blue Mountain.

Overall, no impact on a scenic vista would occur with implementation of the Project and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 18 b. Would the project substantially damage scenic resources, including, but not limited to trees, rock outcroppings and historic buildings within a State scenic highway? No Impact. The proposed Project is not located along a State scenic highway, and there are no state scenic highways located within the Project vicinity.3 Therefore, the Project will not affect any scenic resources within a State scenic highway. No impact would occur and no mitigation is required. c. Would the project, in non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point.) If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? Less than Significant Impact. As of July 1, 2019, the United States Census Bureau estimated the City’s population to be 52,148 persons and the City’s land area to be approximately 15.32 square miles.4 The
Project is located in an area with at least 1,000 persons per square mile (3,404 people per square mile) and therefore meets the definition of Urbanized Area under Section 15387 of the CEQA Guidelines.

During construction, the construction vehicles and equipment would be visible during the removal of existing bridge, placement of the fill, the laying of asphalt material, and other visible general construction activity (i.e., utility relocation). However, the presence of construction vehicles would be temporary and would cease once construction is complete. Due to the temporary nature of construction activities, impacts to visual character of the site and its surroundings would be less than significant during construction. No mitigation is warranted.

The major scenic resource in the City of Colton is the Santa Ana River and its surrounding natural area.

Views of the La Loma Hills (within the City) and Blue Mountain (located within the City of Grand Terrace).

The Project consists of removal of the existing bridge crossing over the abandoned UPRR corridor and replacing it with fill to allow development of road to connect Barton Road in lieu of a new bridge. The Project site itself is not zoned by the City of Colton as Barton Road is a public right-of-way owned by the two cities. Approximately 4,500 square feet will be acquired to increase the right of way at the location of the existing bridge to 50 feet in each direction plus approximately 700 square feet of permanent right of way acquisition will be needed in front of APN 027522316. This parcel is located in the City of Grand Terrace and is currently zoned as Restricted Manufacturing; however, once acquisition occurs the portion of the parcel will become right-of-way for Barton Road. While the Project will alter the existing visual condition of the site (temporarily during construction), it would not conflict with applicable zoning and other regulations governing scenic quality, and impacts to the visual character or quality of the site and its surroundings would be less than significant. No mitigation is required. d. Would the project create a new source of substantial light or glare that would adversely affect daytime or nighttime views in the area?
No Impact. Construction of the Project will be limited to between the hours of 8:00 a.m. and 8:00 p.m. on any day except Sunday or between the hours of 9:00 a.m. and 8:00 p.m. on Sunday in accordance with

No agricultural operations are located on, adjacent to, or near the proposed Project site. The proposed Project site is designated as “Urban and Built-Up Land”.6 As no Prime or Unique Farmlands or Farmland of Statewide Importance (Important Farmlands) are located within or adjacent to the proposed Project site, no conversion of such Important Farmland categories will occur. No impact related to this issue would occur and no mitigation is required.
b. Would the project conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. Williamson Act contracts restrict land development of contract lands.7 These contracts typically limit land use to agriculture, recreation, and open space, unless otherwise stated in the contract.

The City of Colton General Plan Update EIR indicates that San Bernardino County does not have any Williamson Act contracts within the City limits or within Colton’s Sphere of Influence.8 The Project site is not zoned, as it is a public roadway located in the Cities of Colton and Grand Terrace. The parcel where the proposed Project will require sliver acquisition is zoned M-1 Light Industrial. Implementation of the proposed Project would not conflict with existing zoning for agricultural use, or Williamson Act contracts.

Therefore, no impact would occur and no mitigation is required. c. Conflict with existing zoning for or cause rezoning of forest land (as defined in Public Resources Code Section 12220(g), timberland (as defined by Public Resources Code Section 4526) or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? No Impact. Neither the Project site nor surrounding properties are zoned for forest land or timberland.

Therefore, the proposed Project would have no impact on forest land or timberland. No mitigation is required.
d. Result in the loss of forest land or conversion of forest land to non-forest use? No Impact. No forest land exists on site. As discussed in response to Checklist Question 3.2c, the proposed Project would not result in the loss of forest land or conversion of forest land to non-forest use. Therefore, no impact would occur and no mitigation is required.
e. Would the project involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use?
No Impact. As discussed in response to Checklist Questions 3.2a and 3.2b, no agricultural operations are located on, adjacent to, or near the proposed Project. The Project site is designated as “Urban and BuiltUp Land” by the Farmland Mapping and Monitoring Program and it is not subject to a Williamson Act Contract. Land surrounding the Project site is occupied by urban uses and is zoned as M-1 Light Industrial.

   
The analysis in this section is based on the Air Quality Report that was prepared for the proposed Project in October 2020 (Appendix A: Air Quality Report).
a. Would the project conflict with or obstruct implementation of the applicable air quality plan? Less than Significant Impact. The Project site is in the South Coast Air Basin (Basin), which is managed by the South Coast Air Quality Management District (SCAQMD). The California Air Resources Board (CARB) has designated the Basin as nonattainment for ozone, respirable particulate matter less than 10 micrometers in size (PM10), and fine inhalable particulate matter less than 2.5 micrometers in size (PM2.5) under the California Ambient Air Quality Standards. Under the National Ambient Air Quality Standards, the United States Environmental Protection Agency (EPA) has designated the status of the Basin as extreme nonattainment for ozone and moderate nonattainment for PM2.5.

The SCAQMD and Southern California Association of Governments (SCAG) are responsible for developing and implementing the Air Quality Management Plan (AQMP) for the Basin. The applicable AQMP is the SCAQMD Final 2016 AQMP.
9 The 2016 AQMP incorporates local General Plan land use assumptions and regional growth projections developed by SCAG to estimate stationary and mobile source emissions associated with projected population and planned land uses. If a new land use is consistent with the local General Plan and the regional growth projections adopted in the 2016 AQMP, then the added emissions are considered to have been evaluated, are contained in the 2016 AQMP, and would not conflict with or obstruct implementation of the regional 2016 AQMP.

The proposed Project is not considered a project of statewide, regional, or area-wide significance (e.g., large-scale projects such as airports, electrical generating facilities, petroleum and gas refineries,

The proposed Project is listed in the 2016 financially constrained Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) Amendment No. 2, which was found to conform by SCAG on July 6, 2017, and by the Federal Transit Administration (FTA)/Federal Highway Administration (FHWA) on August 1, 2017. On September 6, 2018, SCAG’s Regional Council adopted the 206 RTP/SCS Amendment No. 3 but conformity determination approval from the FHWA is pending. The proposed Project is listed in the 2017 Federal Transportation Improvement Program (FTIP) 17-00 under ID No.

SDBSL08. The 2017 FTIP Consistency Amendment 17-18 was approved by SCAG on February 23, 2018, and by FTA/FHWA on March 26, 2018. The design concept and scope on the proposed Project is consistent with the Project description in the 2016 RTP and 2017 FTIP and the “open to traffic” assumptions of the SCAG’s regional emissions analysis.

No changes are proposed to either the Colton or Grand Terrace General Plan Land Use Designations and zoning designations as the proposed Project would occur within the Barton Road right-of-way. A small portion of parcel APN 0275-223-16 will be acquired by the proposed Project; however, the remainder of the parcel will not be redesignated to a new land use nor will it be rezoned. Overall, the proposed Project is not growth inducing, rather it is being implemented to improve safety along Barton Road. The proposed Project was already assumed in SCAG’s regional emissions analysis as such, the proposed Project is consistent with the 2016 AQMP. Impacts would be less than significant and no mitigation is required. b. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard?
Less than Significant with Mitigation Incorporated. Emission Factors (EMFAC) is California’s federally approved on-road mobile source emission inventory model that reflects California-specific driving and environmental conditions, fleet mix, and mobile source regulations. EMFAC is a computer model used for estimating emission rates for on-road mobile sources in California for calendar years 2000 to 2050. The EMFAC Model was used to determine emissions of the proposed Project.

No single project is sufficient in size, by itself, to result in nonattainment of ambient air quality standards.

Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. The SCAQMD developed the thresholds of significance based on the level above which a project’s individual emissions would result in a cumulatively considerable contribution to the Basin’s existing air quality conditions. Therefore, a project that exceeds the SCAQMD project-specific thresholds would also have a cumulatively considerable contribution to a significant cumulative impact.

Construction Emissions. During construction, short-term degradation of air quality may occur due to the release of particulate emissions generated by excavation, grading, hauling, and other activities related to construction. Emissions from construction equipment also are anticipated and would include carbon monoxide (CO), nitrogen oxide (NOx), volatile organic compounds (VOC), directly emitted PM (PM2.5 and PM10), and Toxic Air Contaminants (e.g., diesel exhaust PM).

Site preparation and roadway construction would involve clearing, cut-and-fill activities, grading, and paving roadway surfaces. Construction-related effects on air quality from most roadway projects would be greatest during the site preparation phase because most engine emissions are associated with the

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 25 excavation, handling, and transport of soils to and from the site. If not properly controlled, these activities would temporarily generate CO, NOx, VOCs, PM10, and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after drying. PM10 emissions would vary from day to day, depending on the nature and magnitude of construction activity and local weather conditions. PM10 emissions would also depend on soil moisture, the silt content of soil, wind speed, and the amount of equipment operating at the time.

Larger dust particles would settle near the source, while finer particles would be dispersed over greater distances from the construction site.

In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, NOx, VOCs, and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase while those vehicles are delayed. These emissions would be temporary and limited to the immediate area surrounding the construction site. Areas within 500 feet of CARB-defined sensitive land uses would be labeled as no-idle areas where material storage/transfer and equipment maintenance activities are not to occur. Existing land uses in the proposed Project area identified as sensitive receptors include single-family residential and multifamily residential units and a mobile home park.

SO2 is generated by oxidation during combustion of organic sulfur compounds contained in diesel fuel.

Off-road diesel fuel meeting federal standards can contain up to 5,000 parts per million of sulfur, whereas on-road diesel is restricted to less than 15 parts per million of sulfur. However, under California law and CARB regulations, off-road diesel fuel used in California must meet the same sulfur and other standards as on-road diesel fuel, so SO2-related issues due to diesel exhaust would be minimal.

The construction emissions were estimated for the proposed Project using the Sacramento Metropolitan Air Quality Management District’s Road Construction Emissions Model, Version 9.0.0, which is consistent with the guidance provided by the SCAQMD for evaluating construction impacts from roadway projects.

Table 3.3.A: Maximum Daily Project Construction Emissions presents the maximum amount of construction-related emissions during a peak construction day for the proposed Project. The PM10 and PM2.5 emissions assume a 50 percent control of fugitive dust as a result of watering and associated dust control measures. The Project construction emissions presented below are based on the best information available at the time of calculations and specify that the schedule for construction of the Project is anticipated to take approximately 14 months.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 26 Construction activities would not last for more than three years at one general location, so constructionrelated emissions do not need to be included in regional and project-level conformity analysis.

Implementation of Mitigation Measure AQ-1 would reduce maximum daily project construction emissions.

Mitigation Measure AQ-1: Prior to the commencement of any construction activities, the construction contractor shall submit a Construction Emission Control Plan for review and approval to the City of Colton Department of Public Works, which shall be implemented during construction. The Construction Emissions Control Plan shall comply with federal, State, and local regulations as specified in the measures below:
• The contractor shall adhere to the Caltrans Standard Specifications for Construction, Sections

14.9-01, 14.9-02, 14.9-03, 18-1.02C, and 18-1.03 (or Greenbook equivalent specifications).

Section 14-9-02 specifically requires compliance by the contractor with all applicable laws and regulations related to air quality, including air pollution control district and air quality management district regulations and local ordinances.
• Water or a dust palliative shall be applied to the site and equipment as often as necessary to control fugitive dust emissions. Fugitive emissions generally must meet a “no visible dust” criterion either at the point of emissions or at the right-of-way line depending on local regulations in compliance with the SCAQMD Rule 403 (Fugitive Dust). • Soil binder shall be spread on any unpaved roads used for construction purposes, and on all project construction parking areas (providing an estimated 50 percent reduction of fugitive emissions) in compliance with the SCAQMD Rule 403 (Fugitive Dust). • Trucks shall be washed as they leave the right-of-way as necessary to control fugitive dust emissions in compliance with the SCAQMD Rule 403 (Fugitive Dust). • Construction equipment and vehicles shall be properly tuned and maintained. All construction equipment shall use low-sulfur fuel as required by California Code of Regulations (CCR) Title 17, Section 93114.
• A dust control plan shall be developed documenting sprinkling, temporary paving, speed limits, and timely revegetation of disturbed slopes as needed to minimize construction impacts to existing communities in compliance with the SCAQMD Rule 403 (Fugitive Dust). • Equipment and material storage sites shall be located as far away from residential uses as practicable. Construction areas shall be kept clean and orderly in compliance with the SCAQMD Rule 402 (Nuisance).
• Within 500 feet of sensitive air receptors, construction activities involving the extended idling of diesel equipment or vehicles will be prohibited to the extent feasible [as required by CCR Title 13, Section 2485(c)].
• Track-out reduction measures shall be used, such as gravel pads at project access points to minimize dust and mud deposits on roads affected by construction traffic, in accordance with the State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4). • All transported loads of soils and wet materials shall be covered before transport, or adequate freeboard (space from the top of the material to the top of the truck) shall be provided to minimize emission of dust during transportation in compliance with the SCAQMD Rule 403.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 27 • Dust and mud that are deposited on paved, public roads due to construction activity and traffic shall be promptly and regularly removed to reduce PM emissions [State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4)]. • To the extent feasible, construction traffic shall be scheduled and routed to reduce congestion and related air quality impacts caused by idling vehicles along local roads during peak travel times (consistent with the traffic control plan approved by the City of Colton Traffic Engineer). • Mulch, hydroseeding or effective equivalent will be installed or vegetation planted as soon as practical after grading to reduce windblown PM. Note that certain methods of mulch/hydroseeding placement may cause dust and visible emission issues and may require controls themselves [Calltrans Standard Specifications for Construction, Sections 18.1-02C (Dust Control Binders) and 18-1.03 (Construction – Dust Palliatives)or Greenbook equivalent].

With implementation of Mitigation Measure AQ-1 impacts pertaining to construction air quality emissions would be reduced to a less than significant impact.

Operational Emissions. The purpose of the Project is to provide safe connectivity between La Cadena and the Barton Road/I-215 interchange and to facilitate efficient access between Colton and Grand Terrace.

The potential impact of the proposed Project on regional vehicle emissions was calculated using traffic date for the Project region and emission rates from the Emission Factor Model, Version 2017 (EMFAC 2017).

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 28 PM2.5 emissions. Additionally, the proposed Project for horizon year 2045 criteria pollutant emissions from vehicle exhaust are all less than the No Build Alternative emissions under the horizon year. The fugitive PM2.5 and PM10 emissions consist of tire wear, brake dust, and re-entrained road dust emissions that are purely related to the increased regional vehicle miles traveled and not solely generated by the proposed Project. The slight increase in fugitive PM10 and PM2.5 emissions will not cause violations of the State PM10 and PM2.5 ambient air quality standards in the South Coast Air Basin. As such, the proposed Project would not substantially contribute or cause deterioration of existing air quality in the area. Impacts will be less than significant and no mitigation measures are required. c. Expose sensitive receptors to substantial pollutant concentrations? Less than Significant Impact. The Air Quality Report included a decision tree to determine if CO local analysis was required for the proposed Project in accordance to the Caltrans Transportation Project-Level Carbon Monoxide Protocol. The following provides a step-by-step explanation of the decision tree where each level cited is followed by a response as to why CO local analysis is required or not required.

1. Is the Project exempt from all emissions analyses? No. The proposed Project is not one of the exempt projects listed in the Caltrans Transportation Project-Level Carbon Monoxide Protocol; therefore, the proposed Project is not exempt from all emissions analyses.

2. Is the Project exempt from regional emissions analyses? No. Because the proposed Project would expand and add traffic lanes to an existing bridge, it is not exempt from regional emission analysis.

3. Is the Project locally defined as regionally significant? No. The proposed Project would replace an existing two-lane bridge with a widened two-lane surface road. Therefore, the proposed Project is not regionally significant.

4. Are there a currently conforming Regional Transportation Plan (RTP) and Transportation Improvement Plan (TIP)? Yes.

5. Is the Project included in the regional emissions analysis supporting the currently conforming RTP and TIP? Yes. The proposed Project is included in the SCAG 2016 RTP and the 2019 FTIP.

6. Has the Project design concept and/or scope changed significantly from that in the regional analysis? No. Regional conformity for the proposed Project has been demonstrated for the RTP and the FTIP. The proposed Project is consistent with the Project description in the 2016 RTP/SCS and the 2019 FTIP.

7. Is the Project in a CO nonattainment area? No. The Project site is in an area that has demonstrated attainment with the federal CO standards.

8. Was the area redesignated as “attainment” after the 1990 Clean Air Act? Yes.

9. Has “continued attainment” been verified with the local Air District, if appropriate? Yes. The U.S.

EPA designated the Basin as attainment/maintenance on June 11, 2007.

10. Does the Project worsen air quality? No. Because the proposed Project would not meet any criteria discussed below, it would not potentially worsen air quality. a. The project significantly increases the percentage of vehicles operating in cold start mode.

Increasing the number of vehicles operating in cold start mode by as little as 2 percent should be considered potentially significant. The percentage of vehicles operating in cold start mode is the same or lower for the bridge under study compared to those used for the intersections in the attainment plan. It is assumed that all vehicles on the Barton Road are in a fully warmed-up mode.

Therefore, this criterion is not met.

INITIAL STUDY/MITIGATED NEGATIVE DECLARATION

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 29 b. The Project significantly increases traffic volumes. Increases in traffic volumes in excess of 5 percent should be considered potentially significant. Increase the traffic volume by less than 5 percent may still be potentially significant if there is also a reduction in average speeds. The proposed Project will improve safety and operation for vehicles traveling on Barton Road between La Cadena and the I-215 interchange. Although the Project would result in lower traffic delays and traffic congestion, the proposed Project would not increase traffic volumes on Barton Road between La Cadena and the I-215 interchange. Therefore, this criterion is not met. c. The Project worsens traffic flow. For uninterrupted roadway segments, a reduction in average speeds (within a range of 3 to 50 miles per hour [mph]) should be regarded as worsening traffic flow. For intersection segments, a reduction in average speed or an increase in average delay should be considered as worsening traffic flow. The proposed Project would represent the lowest volume-to-capacity ratio for the Project’s roadway segment of Barton Road between La Cadena and the I-215 interchange under Opening Day (2023) and Horizon Year (2045) conditions. Because the Project would not worsen traffic flow, rather expanding existing lanes to provide improvements to traffic flow and safety, this criterion is not met.

Based on the CO protocol steps discussed above, the proposed Project would be considered satisfactory, and no further CO analysis is needed.

The U.S. EPA modified the nitrogen dioxide (NO2) NAAQS to include a 1-hour standard of 100 part per billion in 2010. Currently, there is no federal project-level NO2 analysis requirement. However, NO2 is among the near-road pollutants of concern. Within the Project area, it is unlikely NO2 standards for sensitive receptors will be approached or exceeded based on the relatively low ambient concentrations of NO2 in the South Coast Air Basin and on the long-term trend toward reduction of NOx emissions. Based on this, a specific analysis of NO2 was not warranted for the proposed Project.

The existing traffic on Barton Road is well below the criteria of 125,000 average daily trips or 10,000 truck trips pertaining to the requirement for Mobile Source Air Toxics Analysis. The proposed Project is not expected to result in a substantial change to automobile or truck volumes on Barton Road or adjacent streets. Consequently, the emission effects of the proposed Project would be low, and it is expected that there would be no appreciable difference in overall Mobile Source Air Toxics Analysis emissions between the No Build Alternative and the proposed Project. Because the emission effects of the proposed Project would be low, it is expected that there would be no appreciable difference in overall Mobile Source Air Toxics Analysis emissions between no development occurring and the proposed Project occurring.

Overall, the proposed Project would not expose sensitive receptors to substantial pollutant concentrations compared to existing emissions and emissions under a No Build Alternative. Impacts would be less than significant and no mitigation measures would be required. d. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Less than Significant Impact. Other emissions, including objectionable odors, may occur during the operation of diesel-fueled equipment during construction of the proposed Project. However, these emissions would be short in duration and are expected to be isolated to the immediate vicinity of the construction site or transport route. SCAQMD Rules 402, 403, and 431.2, as well as Title 13, Section 2449(d)(d) of the CCR, require the Project applicant to include implementation of standard control measures for fugitive dust and diesel equipment emissions. Additionally, operators of off-road vehicles

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 30 (i.e., self-propelled diesel-fueled vehicles 25 horsepower and up that were not designed to be driven on road) are required to limit vehicle idling to five minutes or less; register and label vehicles in accordance with CARB Diesel Off-Road Online Reporting System; restrict the inclusion of older vehicles into fleets; and retire, replace, or repower older engines or install Verified Diesel Emission Control Strategies (i.e., exhaust retrofits). The SCAQMD Rule 402 regarding nuisances states: “A person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause injury or damage to business or property.” Adherence to these rules is standard regulatory policy for all construction projects in California and would reduce impact levels from other emissions such as objectionable odors to less than significant. No mitigation is required.

Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated. The proposed Project site is currently occupied by Barton Road and the Barton Road Bridge over the abandoned UPRR corridor. A Biological Study Area (BSA) was created to encompass the proposed Project footprint and typical habitats in the immediate project vicinity that may be directly or indirectly affected by the proposed Project. The BSA includes the Barton Road right-of-way between the east side of the South Terrace Avenue intersection in the City of Colton and extends to approximately 75 feet west of the intersection of Grand Terrace Avenue in the City of Grand Terrace. Vegetative communities within the BSA consist of nonnative grasslands and ornamental trees and shrubs. No natural communities are present in the BSA.

According to the California Natural Diversity Data Base maintained by the California Department of Fish and Wildlife (CDFW)10 and the California Native Plant Society Inventory of Rare and Endangered Plants,11 there are several records of species of plants and animals or sensitive plant associations that are found within the San Bernardino South, California USGS 7.5‐minute quadrangle. Review of these databases indicate that 54 special-status species as being potentially present within the vicinity of the BSA. Of the 54 special-status plant and animal species potentially present in the BSA, 19 are federally/State listed as threatened or endangered, and one is a candidate for State listed as Endangered. No suitable habitat is present for any of the 19 federally/State listed species or single candidate species due to the disturbed/developed site conditions. In addition, no designated critical habitats occur within the BSA.

Thirty-four of the 54 species listed are non-listed special-status species with potential to occur in the Project area. Habitat is not present for 33 of the non-listed special status species in the BSA due to the disturbed/developed conditions; however, habitat is presented for one species, the western yellow bat.

The western yellow bat may utilize the palm trees in the BSA for roosting and may use habitat in the BSA for foraging activities. Implementation of the proposed Project may require removal of ornamental trees, as part of roadway construction. As such, the proposed Project has the potential to affect the yellow bat as well as other non-special status bat species that may use ornamental vegetation for roosting within the BSA. To reduce potential impacts to the yellow bat and other bat species, the following mitigation measures would be implemented.

Mitigation Measure BIO-1: Prior to construction, an approved bat biologist shall be retained by the Project proponent to conduct a bat assessment survey to determine the presence or absence of bat species that may occur within the Project limits. Should the presence of bat species be determined during this assessment, the following measures shall be implemented:
• Nighttime exit counts and acoustic surveys shall be performed by a qualified bat biologist at all structures and palm trees that may be subject to project-related impacts. These surveys shall be performed during the recognized bat maternity season (April 1 through August 31, but preferably in June or July) and as far in advance of construction as possible in order to provide adequate time for mitigation planning.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 33 • Construction activities at structures housing maternity colonies shall be coordinated with an approved bat biologist and CDFW.
• If direct impacts to bat-roosting habitat are anticipated, humane evictions and exclusions of roosting bats shall be performed under the supervision of an approved bat biologist after August 31 in the fall (September or October) prior to any work activities that would result in direct impacts or direct mortality to roosting bats. This action shall be performed in coordination with the CDFW. To avoid potential mortality of flightless juvenile bats, evictions and exclusions of bats cannot be performed during the maternity season (April 1 through August 31). Winter months are also inappropriate for bat eviction because not all individuals in a roost will emerge on any given night. In addition, long-distance movements to other roost sites are more difficult during the winter when prey availability is scarce, resulting in high mortality rates of evicted bats. • Alternative bat-roosting habitat structures shall be installed on the structures prior to the eviction/exclusion of bats from that structure. The design, numbers, and locations of these roost structures shall be determined in consultation with an approved bat biologist. • If permanent, direct impacts to bat-roosting habitat are anticipated and a humane eviction/exclusion is performed, alternative permanent roosting habitat shall be provided to ensure no net loss of bat-roosting habitat. This action shall be coordinated with the CDFW, and locations of these roost structures shall be determined in consultation with an approved bat biologist to ensure that the installed habitat provides adequate mitigation for impacts. • The loss of a night roost can negatively affect the use of a foraging area, and consequently may result in reduced fecundity in species that are already slow to reproduce. If night roosting is confirmed at any of the structures within the proposed Project area, the following measure to minimize potential impacts to night-roosting and foraging bats shall be implemented:
o At structures where night roosting is suspected or confirmed, work shall be limited to the daylight hours to the greatest extent feasible to avoid potential disruption of foraging. If night work cannot be avoided, night lighting shall be focused only on the area of direct work, airspace access to and from the roost features of the structure shall not be obstructed, and light spillover into the adjacent foraging areas shall be minimized to the greatest extent feasible.

Through implementation of Mitigation Measure BIO-1, impacts to species identified as a candidate, sensitive, or special-status would be reduced to less than significant levels with mitigation incorporated.b.Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? No Impact. Certain habitats/natural communities are considered to be of special concern based on, 1) federal, State, or local laws regulating their development; 2) limited distributions; and/or 3) whether they support the habitat requirements of special-status plants or animals. Per the Natural Environment Study (Minimal Impacts), no riparian habitat, sensitive natural communities, or wetland habitat is located on the Project site. Therefore, no impact would occur to any riparian habitat or other sensitive natural community. No mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 34 c. Have a substantial adverse effect on State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
No Impact. The U.S. Army Corps of Engineers regulates discharges of dredge or fill material into water of the U.S. including wetlands and non-wetland bodies of water that meet specific criteria. To be considered a jurisdictional wetland under Section 404 of the Federal Clean Water Act (CWA), an area must possess three wetland characteristics: hydrophytic vegetation, hydric soils, and wetland hydrology. No potential jurisdictional features were found to be present within the Project limits.

Per the Natural Environment Study (Minimal Impacts), no drainages, vernal pools, or other riparian or wetland areas are located on site; therefore, the Project would not affect potentially jurisdictional waters.

The Project is not subject to the regulatory authority of the U.S. Army Corps of Engineers under Section 404 of the CWA, the Regional Water Quality Control Board (RWQCB) under Section 401 of the CWA, or the CDFW under Sections 1600 et seq. of the California Fish and Game Code. Therefore, the proposed Project would have no effects on State or federally protected wetlands. No impact would occur and no mitigation is required.
d. Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
Less than Significant with Mitigation Incorporated. Habitat fragmentation occurs when a single, contiguous habitat area is divided into two or more areas, or where an action isolates two or more new areas from each other. Isolation of habitat occurs when wildlife cannot move freely from one portion of the habitat to another or to/from one habitat type to another. Habitat fragmentation may occur when a portion of one or more habitats is converted into another habitat, as when scrub habitats are converted into annual grassland habitat because of frequent burning. Wildlife movement includes seasonal migration along corridors, as well as daily movements for foraging. Examples of migration corridors include areas of unobstructed movement for deer, riparian corridors providing cover for migrating birds, routes between breeding waters and upland habitat for amphibians, and between roosting and feeding areas for birds.

The Project site is located on Barton Road in an urbanized area straddling the city boundary of Colton and Grand Terrace. The Project site does not function as a wildlife corridor; however, colonies of bats could use the palm trees within the Project boundary for roosting and nursery sites. Impacts to bats would be reduced through implementation of Mitigation Measure BIO-1 as identified above in Section 3.4(a).

Existing ornamental vegetation within the Project boundary could also support nesting raptors, specialstatus birds, and other migratory bird species between February 15 through August 31 (bird breeding season); therefore, the proposed Project (specifically during construction) may result in direct or indirect impacts to nesting birds. Although the Project does have potential to affect migratory/nesting birds, implementation of Mitigation Measure BIO-2 would protect migratory birds during the nesting bird season when unfledged offspring would not be able to safely flee the site during construction through the provision of appropriate buffers within which construction would not be allowed.

Mitigation Measure BIO-2: If feasible, project construction and any vegetation removal should begin outside of bird breeding season (typically between September 1 and February 14). In the event that project construction cannot be conducted outside the bird breeding season, and vegetation will be removed, focused surveys shall be conducted by a qualified biologist prior to ground-disturbing

This buffer shall be clearly marked in the field by construction personnel under guidance of the qualified biologist, and construction or clearing shall not be conducted within this zone until the qualified biologist determines that the young have fledged or the nest is no longer active. Nesting bird habitat within the BSA shall be resurveyed during bird breeding season if there is a lapse in construction activities longer than seven days.

Implementation of Mitigation Measures BIO-1 and BIO-2 would reduce the Project’s interference with the movement of any native resident or migratory species and would reduce impacts to native wildlife nursery sites. Impacts would therefore be less than significant with mitigation incorporated. e. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?
Less than Significant Impact. City of Grand Terrace Municipal Code Section 12.18.100, “Removal,” prohibits tree removal or injury within City streets and parkways without a permit. City of Colton Municipal Code Sections 12.20.040 and 12.20.041 requires permits for planting, trimming, removal, chemical treatment or otherwise disturb any City tree and provides a list of tree protection guidelines, respectively. The proposed Project would require the removal of trees to increase the right-of-way for Barton Road and implementation of sidewalks and a Class II bicycle lane in each direction of the road. The Project proponent, as a condition of approval, would be required to obtain tree permits from each City in order to ensure compliance with each cities Municipal Code Sections. As no conflict with any local policies or ordinances protecting biological resources would occur, no mitigation is required. The Project would not conflict with any ordinances protecting biological resources, such as trees, and impacts would be less than significant.
f. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan? No Impact. The Project site is not within any adopted habitat conservation plans, natural community conservation plans, or any other regional planning areas identified by the U.S. Fish and Wildlife Service, CDFW, or the cities of Colton and Grand Terrace.
12,13 Therefore, implementation of the proposed Project would not conflict with the provisions of any adopted local or regional conservation plans. No impact to adopted habitat conservation plans would occur and no mitigation is required.

The analysis in this section is based on the Historic Property Survey Report (HPSR) and Archaeological Survey Report (ASR) for the Barton Road Bridge Removal and Road Construction that were both prepared for the proposed Project in August 2020 (Appendix C: Historic Survey Report [HPSR] and Archaeological Survey Report [ASR]).
a. Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5?
b. Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5?
Less than Significant with Mitigation Incorporated. Pursuant to CEQA Guidelines §15064.5, the term “historical resource” shall include:
(1) A resource listed in, or determined to be eligible by the State Historical Resources Commission for listing in, the California Register of Historical Resources (Pub. Res. Code §5024.1, Title 14 CCR, Section 4850 et seq.).
(2) A resource included in a local register of historical resources, as defined in Section 5020.1(k) of the Public Resources Code or identified as significant in an historical resource survey meeting the requirements Section 5024.1(g) of the Public Resources Code, shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant. (3) Any object, building, structure, site, area, place, record, or manuscript which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be an historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing on the California Register of Historical Resources (Pub. Res. Code, § 5024.1, Title 14 CCR, Section 4852) including the following:

A. Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage.

C. Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values.

D. Has yielded, or may be likely to yield, information important in prehistory or history.

A “substantial adverse change” to a historical resource, according to Public Resources Code (PRC) §5020.1(q), “means demolition, destruction, relocation, or alteration such that the significance of a historical resource would be impaired.”
The Historic Property Survey Report prepared for the proposed Project indicated that there have been 17 cultural resource studies previously conducted within one mile of the Project site, two of which included parts of the Project site. A linear cultural resource transects the Project site (36-006101, the historic period UPRR route) and 25 additional cultural resources have been documented within one mile of the Project site. The additional cultural resources include prehistoric (habitation site, rock shelters, milling features, and artifactscatters) and historic period (rock shelter) archaeological resources, along with historic period utilities, railroads, water conveyance systems, a residence, school, and bridge. The segment of UPRR route transecting the Project site was evaluated in 2009 as not eligible for the National Register either individually or as contributing segments to the overall alignment. The Barton Road Bridge is listed in the California Historical Significance Local Agency Bridge List as a Category 5 Bridge; however, it is not eligible for the National Register. With the exception of the Barton Road Bridge, none of the resources identified is listed in any of the registers, directories, or inventories. The nearest prehistoric resource (a habitation site and artifact scatter) was documented approximately 0.57 mile north of the proposed Project site.

Additional previous research indicated that two additional built environment resources (21842 Grand Terrace Road and 21892 Grand Terrace Road); however, these two historic period residences were evaluated as not eligible for the National Register and concurred with by the State Historic Preservation Office in 2011.

Due to the minimal results of the records search and the survey conducted for the proposed Project, along with the average depth of road subgrades (3+ feet) and severe disturbance of urban road right-of-way, there is a small potential for intact subsurface cultural deposits being found during Project construction activities. If previously unidentified cultural materials are unearthed during project construction, the following mitigation measure shall be implemented to reduce potential impacts to historic and archaeological resources:

Mitigation Measure CUL-1: If deposits of prehistoric or historical archaeological materials are discovered during non-monitored Project activities, all work within 25 feet of the discovery shall be redirected and a qualified archaeologist contacted, if one is not present, to assess the situation, consult with agencies as appropriate, and make recommendations for the treatment of the discovery. The City of Colton and Grand Terrace shall also be notified. Project personnel shall not collect or move any archaeological materials uncovered by construction activities.

Any adverse impacts to the finds shall be avoided by Project construction activities. If avoidance is not feasible, the archaeological deposits shall be evaluated to determine if they qualify as a historical resource or unique archaeological resource, or as historic property. If the deposits do not so qualify, avoidance is not necessary. If the deposits do so qualify, adverse impacts on the deposits shall be avoided, or such impacts shall be mitigated. Mitigation may consist of, but is not limited to, recovery and analysis of the archaeological deposit; recording the resource; preparing a report of findings; and

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 38 accessioning recovered archaeological materials at an appropriate curation facility. Educational public outreach may also be appropriate. Upon completion of the assessment, the archaeologist shall prepare a report documenting the methods and results, and provide recommendations for the treatment of the archaeological deposits discovered. The report shall be submitted to the City of Colton and City of Grand Terrace.

With implementation of Mitigation Measure CUL-1, impacts to “historical resources” as defined under CEQA Guidelines §15064.5 or “archaeological resources” pursuant to CEQA Guidelines §15064.5 would be reduced to less than significant levels with mitigation incorporated. c. Disturb any human remains, including those interred outside of dedicated cemeteries? Less than Significant Impact. No known human remains are present on the Project site and there is no evidence that Native Americans are buried on the Project site. In the unlikely event that human remains are encountered during Project construction, the proper authorities (i.e., San Bernardino County Coroner) shall be notified, and standard procedures for the respectful handling of human remains during the earthmoving activities will be followed. Construction contractors are required to adhere to CCR Section 15064.5(e), PRC Section 5097, and Section 7050.5 of the State’s Health and Safety Code. In the event of an unanticipated discovery of a human burial, human bone or suspected human bone, or funerary objects associated with a human burial, the law requires all excavation or grading in the vicinity of the find halt immediately, the area of the find be protected, and the contractor immediately notify the County Coroner of the find. The construction contractor, project proponent, and the County Coroner are required to comply with the provisions of CCR Section 15064.5(e), PRC Section 5097.98, and Section 7050.5 of the State’s Health and Safety Code. Compliance with these provisions would ensure that any potential impacts to unknown buried human remains would be less than significant by ensuring appropriate examination, treatment, and protection of human remains as required by State law. No specific mitigation is required.

a. Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? Less than Significant Impact. The Project’s consumption of energy during construction is calculated via the California Emission Estimator Model (CalEEMod), as detailed in Appendix A: Air Quality Report.

Energy consumption during operation of the proposed Project has not been considered as the proposed Project includes removal of an existing bridge, replacement with fill and new roadbed to reconnect Barton Road, installation of Class II bicycle lanes, and sidewalks for improved safety and pedestrian/bicyclists connection.

The project’s consumption of energy during construction has been calculated via CalEEMod. The CalEEMod output for energy consumption incorporates project compliance with SCAQMD Rule 431.2, Title 13-Section 2449 of the California Code of Regulations. Adherence to this regulation, including the implementation of Best Available Control Measures (BACM), is a standard requirement for any construction or ground disturbance activity occurring within the South Coast Air Basin. BACMs include, but are not limited to, requirements that the Project proponent utilize only low-sulfur fuel (i.e., having a sulfur content of 15 parts per million by weight or less); ensure off-road vehicles (i.e., self-propelled dieselfueled vehicles 25 horsepower and higher that were not designed to be driven on road) limit vehicle idling to five minutes or less; register and label vehicles in accordance with the CARB Diesel Off-Road Online Reporting System; restrict the inclusion of older vehicles into fleets; and retire, replace, or repower older engines or install Verified Diesel Emission Control Strategies (i.e., exhaust retrofits). Additionally, the construction contractor will recycle/reuse at least 50 percent of the construction material (including, but not limited to, proposed aggregate base, soil, mulch, vegetation, concrete, lumber, metal, and cardboard) and use “Green Building Materials,” such as those materials that are rapidly renewable or resource efficient, and recycled and manufactured in an environmentally friendly way, for at least 10 percent of the Project, in accordance with California Department of Resources Recycling and Recovery (CalRecycle) regulations.

Construction Energy Usage. Approximately 5,500 cubic yards of soil will be removed as part of the proposed Project, and 4,300 cubic yards of fill will be imported to the Project site in order to bring the bridge area to grade with Barton Road. The CalEEMod output assumes 330 daily vehicle miles traveled (VMT) for asphalt hauling emissions and 2,360 daily VMT for worker commute emissions. One crawler

During paving activities, one paver, one paving equipment, one roller, one signal board, and two tractors/loaders/backhoes will be used during this stage of construction.

Based on these construction assumptions, construction activities would consume a total of approximately 8,825.60 gallons of gasoline and 1,488,601 gallons of diesel fuel consumption over the 14-month construction period for the proposed Project. Construction of the proposed Project would not result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources. Impacts would be less than significant and no mitigation is required. b. Conflict with or obstruct a State or local plan for renewable energy or energy efficiency? Less than Significant Impact. The Project would be required to comply with codes pertaining to energy conservation standards as stated in Response to Question 3.6a in effect at the time of construction.

Therefore, the proposed Project would be consistent with applicable plans related to renewable energy and energy efficiency. Impacts would be less than significant and no mitigation is required.

ii Strong seismic ground shaking?
iii Seismic-related ground failure, including liquefaction? iv Landslides?
i. No Impact. The Alquist-Priolo Earthquake Fault Zoning Act (Act) mitigates fault rupture hazards by prohibiting the development of structures for human occupancy across the trace of an active fault.

The Act requires the State Geologist to delineate “Earthquake Fault Zones” along faults that are “sufficiently active” and “well defined.” The boundary of an “Earthquake Fault Zone” is generally 500 feet from major active faults and between 200 and 300 feet from well-defined minor faults. Based on the information published by the Department of Conservation, State of California the Project site is not located within an Alquist-Priolo Special Study Zone. 14 The Rialto-Colton Fault line is approximately

1.6 miles northeast of the Project site.15 Therefore, no impact related to fault rupture would result from the implementation of the project. No mitigation is required. ii. Less than Significant Impact. Like all of southern California, the Project site has and will continue to be subject to ground shaking generated from activity on local and regional faults. Based on United States Seismic Design Maps, the proposed structures may be subject to and must accommodate up to a maximum site horizontal acceleration of 0.910g with two percent probability of being exceeded in 50 years.
16 No permanent occupation of the site would occur as the Project includes replacement of Barton Road Bridge with a filled new portion of Barton Road. In addition, the proposed Project is removing a seismically deficient bridge and replacing it with an at-grade roadway which is a beneficial impact to the traveling public. Impacts would be less than significant because the proposed Project would not construct large-scale, habitable structures or expose site visitors to any geologic or seismic hazards. No mitigation is required.
iii. No Impact. Liquefaction occurs when loose, unconsolidated, water-laden soils are subject to shaking, causing the soils to lose cohesion. Review of the California Department of Conservation Hazard Map indicates the Project site is not in an area susceptible to seismically induced liquefaction.17 Therefore, no impacts related to liquefaction risk are anticipated to occur and no mitigation is required. iv. No Impact. The Project site is characterized by flat topography.

Therefore, the likelihood of a landslide on the Project site is low and no impacts associated with landslides would occur. No mitigation is required. b. Result in substantial soil erosion or the loss of topsoil? Less than Significant Impact. The proposed Project site is currently occupied by Barton Road and the Barton Road Bridge spanning the abandoned UPRR corridor. The proposed Project would include the removal of Barton Road Bridge, which will be replaced by fill, to develop a new roadbed that will connect to the existing Barton Road. Approximately 5,500 cubic yards of soil will be removed from the Project site, and replaced with approximately 4,300 cubic yards of fill to bring the bridge area to grade with Barton Road. The proposed Project would implement standard erosion control measures in accordance with Caltrans, the City of Colton Municipal Code Chapter 15.22 Floodplain Management Regulations, and the City of Grand Terrace Municipal Code Chapter 15.62 Floodplain Management, which would reduce substantial soil erosion. The proposed Project will also remove and reconstruct the drainage outlet west of Grand Terrace Avenue and construct a drainage culvert across Barton Road in the vicinity of the abandoned UPRR corridor. These design features will convey stormwater once the Project is complete and would assist in reducing soil erosion and loss of topsoil downstream and in off-site locations around the Project site. Compliance with City’s Municipal Code and National Pollutant Discharge Elimination System (NPDES) requirements would ensure that the proposed project would have a less than significant impact related to soil erosion or loss of topsoil. No mitigation is required. c. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-site or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse?
Less than Significant Impact. Liquefaction occurs primarily in saturated, loose, fine-to-medium-grained alluvial soils in areas where the groundwater table is within 50 feet of the surface. Shaking suddenly causes soils to lose strength and behave as a liquid.

Lateral spreading is a type of liquefaction-induced ground failure associated with the lateral displacement of surficial blocks of sediment resulting from liquefaction in a subsurface layer. Once liquefaction transforms the subsurface layer into a fluid mass, gravity plus the seismic inertial forces may cause the mass to move downslope toward a free face (such as a river channel or an embankment). Lateral spreading may cause large horizontal displacements and such movement typically damages pipelines, utilities, bridges, and structures.

Factors that contribute to slope failure and landslides include slope height and steepness, shear strength and orientation of weak layers in the underlying geologic units, and pore water pressures.

Ground subsidence is typically a gradual settling or sinking of the ground surface with little or no horizontal movement, although fissures (cracks and separations) can result from lowering of the ground surface.

Most of the damage caused by subsidence is the result of oil, gas, or groundwater extraction from below the ground surface. Ground subsidence may occur as a response to natural forces such as earthquake

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 44 movements, which can cause abrupt elevation changes of several feet or densification of low density granular soils during an earthquake event that may cause several inches of settlement.

Hydrocompaction, or soil collapse, typically occurs in recently deposited Holocene (less than 11,000 years before present time) soils that were deposited in an arid or semi-arid environment. Soils prone to collapse are commonly associated with man-made fill, wind-laid sands and silts, and alluvial fan and mudflow sediments deposited during flash floods. Sudden substantial settlement may occur when saturated, collapsible soils lose their cohesion. An increase in surface water infiltration (such as from irrigation) or a rise in the groundwater table, combined with the weight of a building or structure, may initiate settlement, causing foundations and walls to crack.

The proposed Project is located on near level topography and is not located in an area subject to liquefaction, landslides, subsidence, lateral spreading, or collapse. As such, the proposed Project has a low susceptibility to such geological hazards.

Where exposure to these hazards cannot be entirely avoided, the Project would implement established engineering and construction criteria designed to reduce the risk associated with unstable soils, landslides, lateral spreading, subsidence, liquefaction, soils collapse, and expansive soils. Compliance with existing regulations and requirements would reduce the risk of unstable geologic soils or units to less than significant levels. No mitigation is required.
d. Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property?
Less than Significant Impact. Expansive soils generally have a substantial amount of clay particles that can give up water (shrink) or absorb water (swell). The change in the volume exerts stress on structures and other loads placed on these soils. The extent or range of the shrink/swell is influenced by the amount and kind of clay present in the soil. The occurrence of these soils is often associated with geologic units having marginal stability. Expansive soils can be widely dispersed and they can occur in hillside areas as well as low-lying alluvial basins.

Soils on the Project site consist of Greenfield sandy loam, 2 to 9 percent slopes. The City of Colton General Plan EIR, Exhibit 4.6-4, shows that the Project site is not located on soils that are subject to expansive conditions. In addition soils that are used for in-fill onsite would be engineered to not be subject to shrink and swell. Based on the location of the Project on non-expansive soils, impacts would be less than significant and no mitigation is required.
e. Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The Project, consisting of road improvements/bridge removal, would not require the construction or expansion of septic tanks or wastewater treatment facilities. Therefore, alternative wastewater disposal systems would not be utilized. No impact would occur and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 45 f. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less than Significant with Mitigation Incorporated. The Project site is underlain by weakly indurated alluvial fan deposits derived from local terrains of plutonic rocks (Qoa), which are Pleistocene in age.19 Pleistocene sediments mapped at the surface have high potential to contain significant nonrenewable paleontological resources, and therefore are considered high to paleontological sensitivity. Pleistocene alluvial sediments elsewhere throughout Riverside and San Bernardino counties and the Inland Empire have been reported to yield significant fossils of extinct animals from the Ice Age. Fossils recovered from these Pleistocene sediments represent extinct taxa including mammoths, mastodons, ground sloths, dire wolves, saber-toothed cats, large and small horses, large and small camels, and bison, as well as plant macro- and microfossils.

The majority of the Project site has already been disturbed due to development of Barton Road, surrounding commercial/industrial uses, and other urbanized uses. Construction activities of the proposed Project will include removal of approximately 5,500 cubic yards of soil, replaced by approximately 4,300 cubic yards of fill to bring the bridge area to grade with Barton Road. It is anticipated excavation will not exceed 16 feet in depth from ground level; as such, the potential to find undiscovered paleontological resources is considered low. Nonetheless, since the proposed Project is located in an area of high paleontological sensitivity, Mitigation Measure GEO-1 is required in the event that unanticipated paleontological resources are unearthed during Project construction.

Mitigation Measure GEO-1: Prior to issuance of grading permits, the City of Colton shall verify that the following note is included on the construction plans:
“If paleontological resources are encountered during the course of ground disturbance, work within 60 feet of the find shall be halted and an exclusionary buffer shall be established. A paleontologist shall be contacted to assess the find for scientific significance. No ground-disturbing activity within the 60-foot exclusionary buffer may occur without the consent of the paleontologist and the City of Colton. If determined to be significant, the fossil(s) shall be collected from the field. The paleontologist may also make recommendations regarding additional mitigation measures, such as paleontological monitoring. Scientifically significant resources shall be prepared to the point of identification, identified to the lowest taxonomic level possible, cataloged, and curated into the permanent collections of a museum repository. If scientifically significant paleontological resources are collected, a report of findings shall be prepared to document the collection.” This measure shall be implemented to the satisfaction of the City of Colton.

Implementation of Mitigation Measure GEO-1 would reduce impacts to paleontological resources to less than significant levels with mitigation incorporated by ensuring paleontological resources, if found, would be subject to scientific recovery and evaluation.

The analysis in this section is based on the Air Quality Report that was prepared for the proposed Project in October 2020 (Appendix A: Air Quality Report).
a. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
Less than Significant Impact. State CEQA Guidelines Section 15064(b) provides that the “determination of whether a project may have a significant effect on the environment calls for careful judgment on the part of the public agency involved, based to the extent possible on scientific and factual data,” and further states that an “ironclad definition of significant effect is not always possible because the significance of an activity may vary with the setting.” Climate change is a global issue and is described in the context of the cumulative environment. Therefore, the Project is considered in the context of multiple sectors and the combined efforts of many industries, including development. The primary greenhouse gas (GHG) emissions generated by the Project would be carbon dioxide (CO2) during Project construction. The following analysis represents an estimate of the Project’s GHG emissions through the quantification of CO2 emissions (Appendix A). It should be noted that methane and nitrous oxide emissions are also anticipated, but are negligible (i.e., less than 1 metric ton per year). The following Project activities were analyzed for their contribution to global CO2 emissions.

Lead agencies may elect to rely on thresholds of significance recommended or adopted by state or regional agencies with expertise in the field of global climate change (CEQA Guidelines Section 15064.7[c]). CEQA leaves the determination of significance to the reasonable of the lead agency and encourages lead agencies and publish thresholds of significance to use in determining the significance of environmental effects.

However, the City of Colton has not established specific quantitative significance threshold for GHG emissions for roadway improvement projects. For all nonindustrial projects, the SCAQMD proposes a screening threshold of 3,000 metric tons CO2 equivalent (MT CO2e) per year. The SCAQMD has determined that projects with emissions less than the screening threshold would not result in a significant cumulative impact. The 3,000 MT CO2e per year screening threshold is used in the analysis below to determine the impact associated with Project construction GHG emissions.

Construction and Operational Emissions. Greenhouse gas emissions associated with the proposed Project will occur over the short term from construction activities, consisting primarily of emissions from equipment exhaust. There would also be long-term GHG emissions associated with Project-related

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 47 changes to vehicular trips. The construction emissions were estimated for the proposed Project using the Sacramento Metropolitan Air Quality Management District’s Road Construction Model (RoadMod, Version 9.0.0). The results are presented below in Table 3.8.A: Construction Greenhouse Gas Emissions.

Table 3.8.A: Construction Greenhouse Gas Emissions
Construction Phase CO2e (MT/ Phase)
Grubbing/Land Clearing (lbs/day) 29.99
Grading/Excavating (lbs/day) 1,014.24
Drainage/Utilities/Sub-Grade (lbs/day) 449.59
Paving (lbs/day) 73.44
Maximum (tons/phases) 1,014.24
Total (tons/construction project) 1,727.58
Source: LSA, Air Quality Report, Table 4-3 Project Construction Greenhouse Gas Emissions, pg. 49, October 2020.

Note: MT=Metric tons; CO2e = Carbon dioxide equivalent; lbs/day = pounds/day As indicated in Table 3.8.A, Project construction would result in total emissions of 1,727.58 MT of CO2e, over the 14-month period of construction activity of the proposed Project. The amount of CO2e emissions generated during Project construction will not exceed the SCAQMD 3,000 MT CO2e per year screening threshold; as such, impacts will be less than significant and no mitigation measures are required.

The proposed Project will have low- to no-potential for an increase in GHG emissions. Construction emissions will be unavoidable, but there will likely be long-term GHG benefits from improved operation and smoother traffic flow along Barton Road and nearby roads. Table 3.8.B: Modeled Annual CO2 Emissions and VMT provides the amount of GHG emissions the proposed Project will generate over its life versus existing conditions (2019) versus a No Build Alternative in Opening Year (2023) and Horizon Year (2045) conditions.

Table 3.8.B: Modeled Annual CO2 Emissions and VMT
Alternative CO2 Emissions (metric tons/year) Annual Vehicle Miles Traveled (VMT)1 Existing/Baseline Year 2019 2.18 3,106,177
Opening Year (2023)
No Build 3.33 5,304,145
Project 2.89 5,304,145
Horizon Year (2045)
No Build 3.44 7,574,670
Project 3.27 7,574,670
Source: LSA, Air Quality Report, Table 4-4 Modeled Annual CO2 Emissions and Vehicle Miles Traveled, by Alternative, pg. 50, October 2020.

Note: Traffic data from Traffic Study Report, emissions calculated using EMFAC2017 with SAFE Rule adjustments factors. 1 Annual VMT values derived from Daily VMT values multiplied by 347, per CARB methodology. CO2 = carbon dioxide; VMT = vehicle miles traveled.

Table 3.8.B shows that the Project in the Opening Year and Horizon Year will generate more CO2 emissions compared to the existing conditions of 2019. The increased buildout of the City of Colton and City of Grand Terrace contributes to this increase and is not solely generated by implementation of the proposed Project.

When the proposed Project (in Opening Year 2023 and Horizon Year 2045 conditions) is compared to a No Build Alternative (in Opening Year 2023 and Horizon Year 2045 conditions), the proposed Project will generate lower amounts of CO2 emissions during Opening and Horizon Year conditions. This will occur due to the reduced congestion generated by implementation of the proposed Project. Therefore, impacts related to the generation of GHG emissions, either directly, indirectly or cumulatively, that may have a significant impact on the environment would be less than significant. No mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 48 b. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
Less than Significant Impact. The CARB, a part of the California Environmental Protection Agency is responsible for the coordination and administration of both federal and State air pollution control and climate change programs within California. In this capacity, the CARB conducts research, sets California Ambient Air Quality Standards, compiles emission inventories, develops suggested control measures, and provides oversight of local programs. The CARB establishes emissions standards for motor vehicles sold in California, consumer products, and various types of commercial equipment. While the City does not have an established Climate Action Plan, it is one of the partnership cities that participates in the San Bernardino County Regional Greenhouse Gas Reduction Plan.

The proposed Project is required to comply with Title 13-Section 2449 of the CCR and the CalRecycle Sustainable (Green) Building Program regulations, which include implementation of standard control measures for construction equipment emissions. Adherence to these regulations, including the implementation of Best Available Control Measures (BACMs) is a standard requirement for any construction or ground disturbance activity occurring within the South Coast Air Basin.

BACMs include, but are not limited to, requirements that the project proponent utilize only low-sulfur fuel (i.e., having a sulfur content of 15 parts per million by weight or less); ensure off-road vehicles (i.e., self-propelled diesel-fueled vehicles 25 horsepower and up that were not designed to be driven on road) limit vehicle idling to five minutes or less; register and label vehicles in accordance with the CARB Diesel Off-Road Online Reporting System; restrict the inclusion of older vehicles into fleets; and retire, replace, or repower older engines or install Verified Diesel Emission Control Strategies (i.e., exhaust retrofits).

Additionally, the construction contractor will recycle/reuse at least 50 percent of the construction material (including, but not limited to, proposed aggregate base, soil, mulch, vegetation, concrete, lumber, metal, and cardboard) and use “Green Building Materials,” such as those materials that are rapidly renewable or resource efficient, and recycled and manufactured in an environmentally friendly way, for at least 10 percent of the Project, in accordance with CalRecycle regulations.

As stated previously, the proposed Project is required to comply with SCAQMD Rule 431.2; Title 13-Section 2449 of the CCR; and CalRecycle/Green Building Program regulations, which include implementation of standard control measures for diesel equipment emissions. Through compliance with BACMs as part of applicable regulatory policies designed to reduce emissions, the proposed Project’s estimated GHG emissions (1,727.58 MT of CO2e/construction period would be less than the SCAQMD Tier 3 threshold of 3,000 MT CO2e/year, as detailed in Table 3.8.A) would support a more sustainable community in accordance with Executive Order S-3-05 and Assembly Bill (AB) 32. Therefore, the proposed Project will not generate greenhouse gas emissions that will have a significant impact on the environment, nor will the Project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases. Associated impacts will be less than significant and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 50 a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?
Less than Significant Impact. Potentially hazardous materials such as fuels, oils, and remnant of creosote treated railroad ties may be transported to and from the Project site during the 14-month construction period.

The transport, use, and storage of hazardous materials during construction would be regulated by the City of Colton Fire Department, Grand Terrace Fire Service, under contract with the San Bernardino County Fire Department, in accordance with the City of Colton Local Hazard Mitigation Plan/City of Grand Terrace Hazard Mitigation Plan, and California Occupational Safety and Health Administration regulations.

Additionally, the United States Department of Transportation Office of Hazardous Materials Safety prescribes strict regulations for the safe transport of hazardous materials by truck and rail on State highways and rail lines, as described in Title 49 of the Code of Federal Regulations, and implemented by Title 13 of the CCR.

As detailed in the City of Colton Local Hazard Mitigation Plan and City of Grand Terrace Hazard Mitigation Plan, the transport, use, and storage of hazardous materials during site preparation and project operation would be conducted pursuant to all applicable local, State, and federal laws, and in cooperation with the San Bernardino County Department of Environmental Health Services, Hazardous Materials Division.

Ground disturbance would include removal of the existing Barton Road Bridge, grubbing of vegetation, excavation, and placement of fill up to Barton Road grade to make a new roadbed in place of the removed bridge. Due to the relatively small size of the Project site and scale of proposed construction activities, construction of the Project is not expected to require hazardous materials or a mixture containing a hazardous material in a quantity at any one time above the thresholds described in California Health and Safety Code Section 25503 and Section 25507(a) (1) through (6).

Compliance with all applicable laws and regulations during Project construction and operation would ensure impacts associated with the routine transport, use, storage, or disposal of hazardous materials remain less than significant. No mitigation is required. b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less than Significant Impact with Mitigation Incorporated. As described previously, the proposed Project would not use or handle significant quantities of hazardous materials. The Initial Site Assessment. prepared for the proposed Project included a records review of the Project site that included selected federal and state environmental regulatory databases as well as responses from state and local regulatory agencies. The Project site was not identified in the current regulatory databases as being a site of hazardous materials concern. The facilities listed in the databases do not appear to represent recognized environmental conditions (REC) to the Project site, with the exception of the following:
• Soils with “black, trace petroleum odor” were encountered in geotechnical boring B-3 (located approximately 100 feet west of the bridge) at a depth of 20 feet below ground surface.

A Limited Site Investigation and Aerially Deposited Lead (ADL) assessment of the Project site was conducted in December 2000. The objective of this investigation was to evaluate the presence of ADL within the shallow shoulders of the unpaved roadway shoulders and evaluate the presence of total

During the investigation, nine shallow soil borings (SB-1 through SB-9) were conducted to a depth of 2 feet below ground surface (bgs) (using hand-auger tooling). One deep soil boring (B-2) was advanced to 31.5 feet bgs (using a truck-mounted hallow-stem auger drill rig). Representative soil samples from each boring were collected, with each documented for soil lithology, color, moisture content, and staining.

The soils encountered generally consisted of alternating layers of silty sand and sand silt. A sandy silt with engineered gravel fill material was collected within 12.5 inches of the deep boring. No soil staining was observed from the soils retrieved from the borings. Twenty-six samples from the borings were selected for laboratory analysis.

VOC concentrations were below the specific laboratory report limit (RL) for soil samples analyzed from the deep boring (20 bgs.) TPH-diesel range organics (DRO) and TPH-motor oil range organics (MORO) were detected in soil boring B-2 at a depth of 20 feet bgs; however, the detected TPH-DRO and TPH-MORO concentrations were several orders of magnitude below their respective environmental screening limits for residential and commercial use.
20 Soil samples were collected to evaluate ADL. Total lead concentrations were detected above the laboratory RL in all but four samples. The detectable concentrations of total lead, total threshold limit concentration (TTLC), ranged from 3.1 to 85 mg/kg, with the maximum total lead concentration in the sample collected at 0.5 feet bgs from soil SB-08-0.5. Further lead analysis, indicated a Soluble Threshold Limit Concentration (STLC) of 6.8 mg/l in sample SB-06-0.5, while the sample one foot bsg at this boring indicated an STLC below the laboratory RL. Elevated lead concentrations, interpreted as ADL, were limited to soil samples collected from 0.5 foot bsg. Total lead concentrations were below the environmental screening limits for commercial use.

Per the investigation, “Based on the field observations and laboratory data, evidence of significant impairment (was) not identified in the areas accessible and investigated, and at the time the investigation was conducted.” Additional assessment of soil in the project area does not appear warranted at this time.

While soil impacts above regulatory screening levels or above the applicable residential and commercial screening levels were not identified at the locations explored, due to current and historical uses, there is the potential that other areas within the project limits may have impacts. Mitigation Measure HAZ-1 has been identified to address potential issues related to any affected soils that may be encountered during the course of project construction.

Mitigation Measure HAZ-1: Prior to the commencement of Project construction, a soil management plan shall be developed to identify the appropriate and applicable procedures to be followed with respect to worker health and safety during future excavations and construction activities in areas of potential soil impacts.

The soil management plan shall detail the appropriate and applicable local, State, and federal regulations regarding the proper characterization, treatment, and/or disposal of any impacted soils encountered during excavation or construction activities. Any impacted soil encountered shall be appropriately handled pursuant to the project soil management plan.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 52 Reconnaissance of the Project site resulted in observation of a stormwater drain near the easement located at 21800 Barton Road, on the northeastern perimeter of the site. No evidence of chemical waste disposal, noxious odors, or other indications of releases were observed near the vicinity of the stormwater drain. Based on observation, the drain does not constitute a REC to the site. One gas pipeline marker (Southern California Gas Company) at the northeastern portion of the Barton Road Bridge, and associated pipeline on the underside of the bridge was observed. It was determined that the gas pipe marker and pipeline does not constitute a REC to the site.

A pole-mounted transformer, owned and maintained by Southern California Edison is located on the southern perimeter of the site (southeast of the Barton Road Bridge); however, no information with regard to polychlorinated biphenyls content of the transformer fluids was observed. Evidence of current or prior release of polychlorinated biphenyls was not observed in the vicinity of the electrical equipment during the site reconnaissance; as such, the pole-mounted transformer does not represent a REC to the site.

Miscellaneous household trash (plastic shopping bags, food wrappers, paper drinking cups) were observed scattered throughout the Barton Road Bridge underpass, on the central portion of the Project site. Based on visual observations, the trash did not appear to be hazardous in nature and no evidence of chemical waste disposal, noxious odors, or other indications of releases were observed near the vicinity of the trash. As such, the household trash does not constitute a REC to the site.

Remnants of 12 railroad ties were observed in the area of Barton Road Bridge underpass, on the central portion of the Project site. The railroad ties appeared to be creosote treated, broken and deteriorating.

As such, the railroad ties do not constitute a REC to the Project site.

As part of the Initial Site Assessment an asbestos survey and lead-based paint (LBP) survey of the Project site was conducted. Suspect asbestos-containing material (ACM) was observed during the field surveys on the concrete abutment, concrete retaining wall, concrete encase around valve and pipe, black asphalt road, black creosote, multicolor texture coat on abutment, and black pipe wrap on 12-inch diameter pipe.

No ACM was detected in the samples collected for analysis. The mastic associated with the road reflectors on Barton Road are assumed to be ACM. Suspect LBP was observed during the site field surveys on the gray pain (guard rail and metal cross beam), white paint (concrete with valve under the bridge, metal bollard on the northeastern portion of the road), yellow paint (gas pipe under the bridge), and the red with blue paint (on the curb on the northwestern portion of the site). Lead and chromium were detected in the samples that were analyzed. Implementation of Mitigation Measure HAZ-2 would ensure that ACMs, LBPs and chromium are appropriately collected during Project construction activities and properly removed from the site.

Mitigation Measure HAZ-2: During construction, the Project contractor shall comply with the occupational Safety and Health Administration Standard 1926.6 related to lead abatement, and all other applicable state and federal requirements for handling and disposal of LBP, ACM, and universal wastes. AS ACM, LBP and chromium has been detected in features existing on the Project site, these materials, during Project construction, shall be abated and removed from the site in accordance with all applicable regulations, including Occupational Safety and Health Administration requirements. The City of Colton shall verify that the abatement and removal of ACM, LBP and chromium has been completed prior to any development activities on the Project site.

INITIAL STUDY/MITIGATED NEGATIVE DECLARATION

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 53 The Project would be constructed and operated in accordance with applicable local, State, and federal laws pertaining to hazardous materials. Since the proposed Project uses would not include significant quantities of hazardous materials, and the Project site does not currently contain any recognized environmental conditions or historical recognized environmental conditions, release of hazardous materials into the environment from construction and operation of the Project is not reasonably foreseeable. Implementation of Mitigation Measures HAZ-1 and HAZ-2 would also reduce the potential impacts associated with soil contaminated with “black, trace petroleum odor”, ACM, LBP, and chromium in demolition materials. Therefore, impacts would be less than significant with implementation of mitigation measures.
c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less than Significant Impact. The nearest school to the Project site is Grand Terrace Elementary School (12066 Vivienda Avenue Grand Terrace) approximately 0.26 mile to the northeast. Interstate 215 is between the proposed Project and Grand Terrace Elementary School. The proposed Project during construction and operation would not emit hazardous materials or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. Impacts will be less than significant and not mitigation is required.
d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
No Impact. Pursuant to Government Code Section 65962.5, the Hazardous Waste and Substances Sites List has been compiled by the California Environmental Protection Agency Hazardous Materials Data Management Program. The Department of Toxic Substances Control (DTSC) compiles information from subsets of the following databases to make up the Cortese List, which includes, but is not limited to:

1. The DTSC list of contaminated or potentially contaminated hazardous waste sites listed in the California Sites database, formerly known as ASPIS, is included;

2. The California State Water Resources Control Board listing of leaking underground storage tanks is included; and

3. The California Integrated Waste Management Board list of sanitary landfills that have evidence of groundwater contamination or known migration of hazardous materials (formerly WB-LF, now AB 3750).

According to the Project specific Initial Site Assessment none of the sites within 500 feet of the Project site nor the Project site itself were included on the Hazardous Waste and Substances Sites (Cortese) List, DTSC (GeoTracker), or RWQCB (EnvironStor) databases. Therefore, no impact related to the Cortese List or other governmental databases compiled pursuant to Government Code Section 65962.5 would occur and no mitigation is required.
e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? No Impact. The Project site is located approximately 5.57 miles northeast of the Flabob Airport in the City of Jurupa Valley and 5.54 miles southwest of the San Bernardino International Airport, which are the

Therefore, the Project would not result in a substantial safety hazard related to airports. No impact would occur and no mitigation is required. f. Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
Less than Significant Impact. During construction of the proposed Project, Barton Road will be temporarily closed between Terrace Avenue and Grand Terrace Avenue. The Cities of Colton and Grand Terrace consider Barton Road an emergency evacuation route in their General Plans. As a condition of approval for the Project, a detour plan will be prepared and distributed to emergency service, fire department, and police department staff that provides service to the Project site and surrounding uses. .

The detour will route traffic around the construction zone on Barton Road via S. Terrace Avenue, De Berry Street, and S. La Crosse Avenue throughout the duration of construction. Once the proposed Project is complete, Barton Road between Terrace Avenue and Grand Terrace Avenue and vehicle flow conditions will be restored back to near existing conditions. Based on the above discussion, implementation of the proposed Project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Impacts would be less than significant and no mitigation measures are required.
g. Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?
Less than Significant Impact. The Project site is not located within or immediately adjacent to a State Responsibility Area or Local Responsibility Area (LRA) designated as a Very High Fire Hazard Severity Zone (VHFHSZ) by Cal Fire.23 The western boundary of the Project site is approximately 995 feet east of an LRA designated as a VHFHSZ. The City of Colton Fire Department provides fire suppression and emergency medical services to the City. Fire Station 213 located approximately 1.28 miles to the north at 1100 South The closest fire station is in Colton on La Cadena Drive which will serve the Project site. The City of Grand Terrace is within the service area of the San Bernardino County Fire Department for fire and rescue services. Fire Station 23 is located at 22582 City Center Court in Grand Terrace and is approximately 1 mile east of the Project site. The Project site is therefore adequately served by fire departments.

The proposed Project will remove the Barton Road Bridge (and replace it with fill and new roadbed) which is susceptible to burning in a fire due to its composition. As such, once the proposed Project is complete, Barton Road will be less susceptible to fire destruction in the area over the abandoned UPRR corridor. The proposed Project does not include features that will expose people or structure (either directly or indirectly) to a significant risk of loss, injury or death involving wildland fire. Impacts will be less than significant and no mitigation measures are required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 56 a. Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality?
Less than Significant Impact. The Cities of Colton and Grand Terrace are co-permittees under Santa Ana Regional Water Quality Control Board (Santa Ana RWQCB) Order number R8‐2010‐0036, NPDES Permit No. CAS618036, also known as the Municipal Separate Storm Sewer System or MS4 permit. The San Bernardino County Water Quality Management Plan was developed to implement compliance with the MS4 permit. The construction of the proposed Project would require ground-disturbing activities that could result in eroded soils and other pollutants entering watersheds, such as the Santa Ana River watershed. Pollutants, such as sediment, nutrients, heavy metals, toxic organics, trash and debris, and contaminants, may be conveyed by storm runoff from impermeable surfaces (e.g., buildings, streets, and parking lots). The City of Colton implements NPDES requirements for surface water discharge for all qualifying activities.

Short-Term Construction. The Project site is in approximately 2.8 acres in size (excess of one acre); therefore, the Project is required to obtain coverage under an NPDES Construction Permit, which includes the submittal of a Notice of Intent (NOI) application to the Santa Ana RWQCB, the receipt of a Waste Discharge Identification Number from the SWRCB, and the preparation of a Storm Water Pollution Prevention Plan (SWPPP) for construction discharges. An SWPPP is a written document that describes the construction operator’s activities to comply with the requirements in the NPDES permit. The SWPPP is intended to facilitate a process whereby the operator evaluates potential pollutant sources at the site and selects and implements Best Management Practices (BMPs) designed to prevent or control the discharge of pollutants in storm water runoff. During the construction period, the Project applicant would use a series of BMPs to reduce erosion and sedimentation. These measures may include the use of gravel bags, silt fences, check dams, hydroseed, and soil binders. The construction contractor would be required to operate and maintain these controls throughout the duration of on-site activities. In addition, the construction contractor would be required to maintain an inspection log and have the log on site to be reviewed by the City of Colton and representatives of the Santa Ana RWQCB.

An NPDES permit would generally specify an acceptable level of a pollutant or pollutant parameter in a discharge (for example, a certain level of bacteria). The permittee may choose which technologies to use to achieve that level. Some permits, however, do contain certain generic BMPs. Table 3.10.A: General Best Management Practices lists BMPs for runoff control, sediment control, erosion control, and housekeeping that may be used during the construction of the proposed Project.

Long-Term Operation. The proposed Project site is located within the jurisdiction of the Santa Ana RWQCB. The overall Project area drains in the westerly direction; however, the abandoned UPRR railroad corridor drains in the northern direction towards the Santa Ana River. The I-215/Barton Road interchange constructed inlets at the easterly limits of the Project boundary and has included several new storm drain inlets and subsurface pipe to collect the runoff from the interchange area. The proposed Project will implement a design concept that perpetuates the existing drainage pattern of the area in order not to impact existing downstream properties.

The Project area has been divided into four drainage areas. Table 3.10.B: Pre-Project Condition Peak Flow Rate for Drainage Areas shows the drainage areas of the Project along with their 100-year flow rate and 10-year flow rate under pre-project construction conditions.

As part of the design, the proposed Project will be required to construct storm drain system improvements to ensure storm drain infrastructure has been sized sufficiently to intercept the Project stormwater runoff.

The drain system improvements are as follows:
• Construction of a 30-inch culvert that will be located under the proposed fill area that will replace the existing Barton Road Bridge. The 30-inch culvert will allow flows to be perpetuated from the south side of Barton Road to the north side of Barton Road in order to sustain the existing drainage pattern. • Construction of two inlet structures that will be located west of the existing Barton Road Bridge. The two inlets will intercept the street surface flow and convey the stormwater runoff to a proposed water quality BMP. After the low flows are treated, the runoff will be conveyed into the proposed 30-inch storm drain.
• Construction of an 18-inch storm drain that will convey the runoff from the two existing inlets into the proposed 30-inch culvert. The existing design connects to an existing circular inlet structure that connects to an existing 8-inch outlet pipe. This design is substandard and must be repaired to provide adequate flood protection for Barton Road.

Table 3.10.C: Post-Project Condition Peak Flow Rate for Drainage Areas shows the peak flow 100-year and 10-year rates for the Project drainage areas once the above design features are in place as part of the proposed Project.

The drainage infrastructure improvements for the proposed Project, as indicated in Table 3.10.C, results in a decrease in Area A flow rates and an increase in flow rates for Area B. The changes in the flowrates for these subareas are attributed to the altering of drainage areas that result from the removal of the Barton Road Bridge and the high point that exists over the railroad corridor. Overall, the changes in flow

Standard Conditions: No mitigation is required; however, compliance with the provisions of the NPDES permit and incorporation of a Final Water Quality Management Plan Low Impact Development (LID) BMPs are regulatory requirements that apply to all projects. These requirements are detailed below as Standard Conditions (SC) HYD-1 through HYD-3 to be included in the conditions of approval for the proposed Project.

Standard Condition HYD-1: Prior to the issuance of a grading permit, the City of Colton Public Works Department shall file and obtain a Notice of Intent (NOI) with the RWQCB in order to be in compliance with the State National Pollutant Discharge Elimination System (NPDES) General Construction Storm Water Permit for discharge of surface runoff associated with construction activities. Evidence that this has been obtained (i.e., a copy of the Waste Discharger’s Identification Number) shall be retained by the City of Colton and submitted to Caltrans for coverage under the NPDES General Construction Permit. The NOI shall address the potential for an extended and discontinuous construction period based on funding availability. This measure shall be implemented to the satisfaction of the Director of the City Engineering Division of the Public Works Department or designee.

Standard Condition HYD-2: Prior to the issuance of a grading permit, the City of Colton Public Works Department shall prepare a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP shall include a surface water control plan and erosion control plan citing specific measures to control on-site and off-site erosion during the entire construction period. In addition, the SWPPP shall emphasize structural and nonstructural Best Management Practices (BMPs) to control sediment and non-visible discharges from the Project site. The SWPPP shall include inspection forms for routine monitoring of the site during both the grading and construction phases to ensure National Pollutant Discharge Elimination System (NPDES) compliance and that additional BMPs and erosion control measures will be documented in the SWPPP and utilized if necessary. The SWPPP shall address the potential for an extended and discontinuous construction period based on funding availability. The SWPPP shall be kept on site for the entire duration of Project construction and shall be available to the local RWQCB for inspection at any time. BMPs to be implemented may include the following:
• Sediment discharges from the site may be controlled by the following: sandbags, silt fences, straw wattles and temporary basins (if deemed necessary), and other discharge control devices. The construction and condition of the BMPs shall be periodically inspected during construction, and repairs shall be made when necessary as required by the SWPPP.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 59 • Materials that have the potential to contribute to non-visible pollutants to storm water must not be placed in drainage ways and must be contained, elevated, and placed in temporary storage containment areas.
• All loose piles of soil, silt, clay, sand, debris, and other earthen material shall be protected in a reasonable manner to eliminate any discharge from the site. Stockpiles shall be surrounded by silt fences and covered with plastic tarps.
• In addition, the construction contractor shall be responsible for performing and documenting the application of BMPs identified in the SWPPP. Weekly inspections shall be performed on sandbag barriers and other sediment control measures called for in the SWPPP. Monthly reports and inspection logs shall be maintained by the contractor and reviewed by the City of Colton and the representatives of the State Water Resources Control Board. In the event that it is not feasible to implement specific BMPs, the City of Colton can make a determination that other BMPs will provide equivalent or superior treatment either on or off site.

This measure shall be implemented to the satisfaction of the Director of the City of Colton Public Works Department or his/her designee.

Standard Condition HYD-3: Prior to issuance of a grading permit, the City of Colton Public Works Department shall submit evidence to Caltrans and put into the Project’s administrative record that the Low Impact Development (LID) Best Management Practices (BMPs) specified in a Final Water Quality Management Plan (a Preliminary WQMP) shall be written into the grading and development plans submitted to the City for review and approval to manage water quality and hydrologic effects of the proposed Project. Specifically, the LID BMPs shall be implemented to ensure the Project meets or exceeds the minimum design capture volume of the site.

Periodic maintenance of LID BMPs during Project operation shall be in accordance with the schedule outlined in a Final WQMP. This measure shall be implemented to the satisfaction of the Director of the City of Colton Public Works Department or designee.

The Preliminary WQMP will be prepared and approved as a routine action during the processing of the project by the City; therefore, it is reasonable to conclude that the required measures and features detailed in a Final WQMP to safeguard water quality would be incorporated into the proposed Project.

Adherence to Standard Conditions HYD-1 through HYD-3 and the requirements included in the NPDES permit, SWPPP, and a Final WQMP would ensure potential water quality impacts remain less than significant. No mitigation is required.
b. Substantially decrease groundwater supplies or interfere with groundwater recharge such that the project may impede sustainable groundwater management in the basin? Less than Significant Impact. The Project site is located within the Riverside Highland Water Company (RHWC) service area, and the San Bernardino Valley Municipal Water District. According to the San Bernardino Valley Municipal Water District 2015 Urban Water Management Plan (UWMP), the RHWC’s water supply consists entirely of groundwater extracted from the San Bernardino Basin Area (Bunker Hill Basin portion), the Rialto-Colton Basin, and the Riverside Basin (Riverside North Basin portion).24 The proposed Project includes removal of Barton Road Bridge over the abandoned UPRR corridor, replacement of the bridge with fill and a new roadbed to connect Barton Road in place of where the bridge

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 60 used to be, installation of drainage improvements, and, installation of sidewalks and Class II bicycle lanes to promoted connectivity for non-motorized transportation between the City of Colton and City of Grand Terrace. All of the actions associated with the proposed Project will occur along the existing Barton Road between South Terrace Avenue and Grand Terrace Road. Therefore, the Project would not substantially contribute to groundwater depletion, nor would it interfere with groundwater recharge. The Project site is not located within a designated groundwater recharge area and it does not propose direct additions or withdrawals of groundwater. Furthermore, the proposed construction does not reach depths that would impair or alter the direction or rate of flow of groundwater.

Through implementation of Standard Condition HYD-3, the LID BMPs specified in a Final WQMP would be implemented to treat the Project site’s minimum design capture volume and on-site storm water runoff will be conveyed off-site in a similar manner as occurring under existing conditions. Periodic maintenance of any BMPs during Project operation will be in accordance with the schedule outlined in the WQMP. Therefore, through implementation of Standard Condition HYD-3, impacts associated with groundwater supplies would be less than significant. No mitigation is required. c. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
i Result in substantial erosion or siltation on or off site? ii Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on or off site?
iii Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? iv Impede or redirect flood flows?
i. Less than Significant Impact. There are no known drainages, ponds, or other places where water collects on the Project site. The overall Project area drains in a westerly direction; however, the abandoned UPRR railroad corridor drains in a northern direction towards the Santa Ana River. The I215/Barton Road interchange constructed inlets at the easterly limits of the Project boundary and has included several new storm drain inlets and subsurface pipes to collect the runoff from the interchange area. The proposed Project will implement a design concept that perpetuates the existing drainage pattern of the area in order not to impact existing downstream properties. Pursuant to Standard Condition HYD-2, the City of Colton will prepare an SWPPP prior to the issuance of grading permits. The SWPPP will include a surface water control plan and erosion control plan citing specific measures to control on-site and off-site erosion during the entire grading and construction period. In addition, the SWPPP will emphasize structural and nonstructural BMPs to control sediment and nonvisible discharges from the site. The SWPPP would include inspection forms for routine monitoring of the site during the 14-month construction period to ensure NPDES compliance and that additional BMPs and erosion control measures will be documented in the SWPPP and utilized if necessary. The SWPPP would address the potential for an extended and discontinuous construction period based on funding availability. Upon completion of construction, the Project site would be paved (similar to existing conditions), which would prevent erosion and siltation of sediments. Through implementation of Standard Condition HYD-2, the Project would not result in substantial erosion or siltation on or off site. Impacts would be less than significant and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 61 ii. Less than Significant Impact. Pursuant to Standard Condition HYD-3, the LID BMPs specified in the Preliminary WQMP would be implemented to convey the Project site’s minimum design capture volume. According to the project-specific Hydrology Study, development of the proposed Project would result in a decrease in Area A flow rates and an increase in flow rates for Area B during 100- year flows. The changes in the flowrates for these subareas are attributed to the altering of drainage areas that result from the removal of the Barton Road Bridge and the high point that exists over the abandoned UPRR corridor. Overall, the changes of flow rate is insignificant and will not adversely affect downstream property owners or downstream receiving waters considering the anticipated 100- year peak flow rate for the Santa Ana River of 140,000 cubic feet per seconds. Periodic maintenance of any required BMPs during Project operation would be in accordance with the schedule outlined in a Preliminary WQMP. With implementation of Standard Conditions HYD-2 and HYD-3, impacts related to substantial alteration of the existing drainage pattern of the site or area or substantial increase in the rate or amount of surface runoff in a manner that would result in on-site or off-site flooding would be less than significant. No mitigation is required. iii. Less than Significant Impact. The CWA delegates authority to the states to issue NPDES permits for discharges of storm water from construction, industrial, and municipal entities to Waters of the United States. The purpose of the MS4 permit is to meet the Santa Ana RWQB’s requirements to mitigate for the negative impact of increases in storm water runoff caused by new development and redevelopment. The project storm water discharge rates cannot exceed the pre-development runoff condition for 2-year 24-hour storm total or the 85th percentile 24-hour storm runoff event by more than five percent to be in compliance with the MS4 post-construction and site design requirements.

The Project is 2.8 acres in size (over one acre in size) and therefore is required to have coverage under the State’s General Permit for Construction Activities (SWPPP). Pursuant to Standard Condition HYD2, a project-specific SWPPP will be prepared and detailed BMPs will be implemented during construction to reduce/eliminate adverse water quality impacts. All impacts related to runoff during site preparation, and construction would be addressed by the SWPPP.

The overall Project area drains in a westerly direction; however, the abandoned UPRR railroad corridor drains in a northern direction towards the Santa Ana River. The I-215/Barton Road interchange constructed inlets at the easterly limits of the Project boundary and has included several new storm drain inlets and subsurface pipes to collect the runoff from the interchange area. The proposed Project will implement a design concept that perpetuates the existing drainage pattern of the area in order not to impact existing downstream properties.

Pursuant to Standard Condition HYD-3, the LID BMPs specified in a Final WQMP will be implemented to treat the Project site’s minimum design capture volume. Additional Project design features, such as maintenance of existing surface flows across the Project site through the proposed BMPs would further maintain the site’s existing drainage pattern and prevent additional sources of polluted runoff.

Periodic maintenance of any required drainage facilities during Project operation will be in accordance with the schedule outlined in the Preliminary WQMP.

Any sources of storm water pollution will be addressed through adherence to NPDES and MS4 permit requirements. Implementation of Standard Conditions HYD-2 and HYD-3 will ensure polluted runoff during site preparation and construction would be addressed by the SWPPP. Therefore, impacts related to the creation or contribution of runoff water that would exceed the capacity of existing or

No mitigation is required. iv. Less than Significant Impact. According to the Federal Emergency Management Agency (FEMA) National Flood Hazard Layer, the Project site is located within Panel 06071C8687J in Zone X, identified as an “Area of Minimal Flood Hazard.” The overall Project area drains in a westerly direction; however, the abandoned UPRR railroad corridor drains in a northern direction towards the Santa Ana River. The I-215/Barton Road interchange constructed inlets at the easterly limits of the Project boundary and has included several new storm drain inlets and subsurface pipes to collect the runoff from the interchange area. The proposed Project will implement a design concept that perpetuates the existing drainage pattern of the area in order not to impact existing downstream properties. The drainage infrastructure improvements for the proposed Project, as indicated in Table 3.10.C, results in a decrease in Area A flow rates and an increase in flow rates for Area B. The changes in the flowrates for these subareas are attributed to the altering of drainage areas that result from the removal of the Barton Road Bridge and the high point that exists over the railroad corridor. Overall, the changes of flow rate is insignificant and will not adversely affect downstream property owners or downstream receiving waters. Therefore, the Project would not impede or redirect flood flows. Impacts would be less than significant and no mitigation is required.
d. Result in flood hazard, tsunami, or seiche zones, or risk release of pollutants due to project inundation?
Less than Significant Impact. According to the FEMA National Flood Hazard Layer, the Project site is located within Panel 06071C8687 in Zone X, identified as an “Area of Minimal Flood Hazard.” According to the City’s General Plan EIR, there are no major dams located within the City of Colton.25 The closest dam inundation area is approximately 2.5 miles to the north east of the Project site along the Santa Ana River floodplain in the vicinity of I-10/I-215 interchange. Considering that the Project site is not near this dam inundation zone, the failure of Seven Oaks Dam and failure of Levee ID 4964 will not be a significant threat to the proposed Project site. In the event that local sheet flooding occurs, as it has in the past, storm drain improvements implemented as part of the proposed Project will be constructed to convey water off-site similar to existing conditions.

There would be a less than significant impact regarding inundation of the proposed Project site by a tsunami because the Project site is approximately 42 miles northeast of the Pacific Ocean. The proposed Project is not located near a lake or open body of water; accordingly, a seiche occurrence that could affect the Project site is highly unlikely. Therefore, impacts associated with release of pollutants due to Project inundation would be less than significant. No mitigation is required. e. Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Less than Significant Impact. As detailed in response to Checklist Question 3.10b, the proposed Project would not substantially contribute to groundwater depletion, nor would it interfere with groundwater recharge. The Project does not propose direct additions or withdrawals of groundwater, as it is a bridge removal and road improvement Project along Barton Road. Furthermore, construction proposed by the

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 63 Project would not involve construction at depths that would impair or alter the direction or rate of groundwater flow.

The implementation of NPDES permit in accordance with Standard Condition HYD-1 ensures that the State’s mandatory standards for maintenance of clean water and the federal minimums are met. Through implementation of the BMPS detailed in an SWPPP pursuant to Standard Condition HYD-2, water quality impacts would be less than significant during construction. Since the Project would not inhibit groundwater recharge potential and would only result in minimal potential increase in the demand for water during construction, the Project would not conflict with any applicable water quality control plan or sustainable groundwater management plan. Impacts would be less than significant and no mitigation is required.

Through implementation of Standard Condition HYD-3, the LID BMPs specified in a Final WQMP will be implemented to treat the Project site’s minimum design capture. Periodic maintenance of any BMPs during Project operation will be in accordance with the schedule outlined in the WQMP. Therefore, through implementation of Standard Condition HYD-3, impacts from conflict with or obstruction of a water quality control plan or sustainable groundwater management plan would be less than significant.

a. Result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
Less than Significant Impact. Two types of short-term noise could occur during construction of the proposed Project. First, construction crew commutes and the transport of construction equipment and materials to the site would incrementally increase noise levels on roadways in the Project area. There would be a relatively high single-event noise exposure potential causing intermittent noise nuisance (passing trucks at 50 feet would generate up to a maximum of 84 A-weighted decibels [dBA]). The effect on longer-term (hourly or daily) ambient noise levels would be small because the hourly/daily construction-related vehicle trips are small when compared to existing hourly/daily traffic volume on Barton Road. The grading and excavation phase of the Project would generate the most trips of all the construction phases (i.e., 84 vehicles per hour or 171 vehicles per day). Barton Road would be used to access the Project site. The existing hourly/daily traffic volumes on Barton Road are estimated to be 596 vehicles per hour or 7,292 vehicles per day. Construction-related traffic would increase traffic noise levels on nearby roads by up to 0.6 dBA. A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment.

Therefore, there would be no incremental increase in ambient noise from construction-related vehicle trips, and short-term, construction-related impacts associated with worker commutes and equipment transport to the Project site would be less than significant and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 67 The second type of short-term noise is related to noise generated during excavation, grading, and building erection on the Project site. Construction is completed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on the site and, therefore, the noise levels surrounding the site as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction-related noise ranges to be categorized by work phase. Table 3.13.A: Typical Maximum Construction Equipment Noise Levels (Lmax) lists typical construction equipment noise levels recommended for noise impact assessments, based on a distance of 50 feet between the equipment and a noise receptor, taken from the 2006 FHWA Roadway Construction Noise Model.28
Typical noise levels at 50 feet from an active construction area range up to 88 dBA Lmax (maximum instantaneous sound level) at 50 feet during the noisiest construction phases. The site preparation phase, which includes excavation and grading of the site, tends to generate the highest noise levels because the noisiest construction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery such as backfillers, bulldozers, draglines, and front loaders. Earthmoving and compacting equipment includes compactors, scrapers, and graders.

Project construction is expected to require the use of a scrapers, bulldozers, and water trucks/pickup trucks. Noise associated with the use of construction equipment is estimated to be between 55 and 85 dBA Lmax at a distance of 50 feet from the active construction area for the site preparation phase. As detailed in Table 3.13.A, the maximum noise level generated by each scraper is assumed to be approximately 85 dBA Lmax at 50 feet. Each bulldozer would generate approximately 85 dBA Lmax at 50 feet. The maximum noise level generated by water trucks/pickup trucks is approximately 55 dBA Lmax at 50 feet.

Each doubling of the sound sources with equal strength increases the noise level by 3 dBA. Assuming that each piece of construction equipment operates at some distance from the other equipment, the worstcase combined noise level during this phase of construction would be 88 dBA Lmax at a distance of 50 feet from the active construction area. The closest residences to the project construction boundary are 90 feet from the project construction boundary and would be exposed to construction noise levels of 83 dBA Lmax after distance attenuation. In addition, noise generated from the construction activities would stop once project construction is completed. Implementation of measures that include compliance with the construction hours specified by the City of Grand Terrace (the City of Colton does not have noise compliance times in their Municipal Code) prohibiting construction activity between the hours of 8:00 p.m. and 8:00 a.m. would reduce construction noise that could affect nearby residences. Additionally, the proposed Project will implement Caltrans Standard Specifications, Section 14-8.02 (as a condition of approval) which specifies that noise levels from the construction contractor’s operations, between the hours of 9:00 p.m. and 6:00 a.m., shall not exceed 86 dBA Lmax at a distance of 50 feet. Therefore, no construction noise impacts would occur with the implementation of measures described above. Shortterm noise impacts would be less than significant and no mitigation is required.

Note: The noise levels reported in this table are rounded to the nearest whole number. 1 The usage factor is the percentage of time during a construction noise operation that a piece of construction equipment is operating at full power. 2 The maximum noise levels were developed based on Specification 721.560 from the Central Artery/Tunnel program to be consistent with the City of Boston, Massachusetts, Noise Code for the “Big Dig” project. Lmax = maximum instantaneous noise level Long-Term Stationary Noise. The proposed Project includes removal of a bridge on Barton Road spanning over the abandoned UPRR corridor. Once removed, the bridge will be replaced by fill and a new portion of Barton Road will be laid. Sidewalks and Class II bicycle lanes will also be constructed as part of the Project to promote pedestrian/bicyclist connection along Barton Road. The proposed Project will not include design features that would generate stationary noise.

Adjacent off‐site land uses would be potentially exposed to stationary‐source noise impacts from the proposed on‐site container and chassis drop‐off and pick‐up activities, forklift operations, heating, ventilation, and air conditioning equipment, and parking lot activities. Therefore, no long-term stationary noise reduction measures are required. No impacts from long-term stationary noise sources would occur and no mitigation is required.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 69 a new portion of Barton Road will be laid. Sidewalks and Class II bicycle lanes will also be constructed as part of the Project to promote pedestrian/bicyclist connection along Barton Road. The proposed Project, once completed, will not generate an increase in average daily traffic (ADT) volumes along Barton Road or other surrounding roads beyond what occurs under existing conditions. Under 23 Code of Federal Regulations (CFR) 772.5, this Project is not considered a Type I Project. A Type I Project is defined as follows:
• The construction of a highway on new location or the physical alteration of an existing highway where there is either:
o Substantial Horizontal Alteration. A project that halves the distance between the traffic noise source and the closest receptor between the existing condition to the future build condition; or, o Substantial Vertical Alteration. A project that removes shielding therefore exposing the line-ofsight between the receptor and the traffic noise source. This is done by either altering the vertical alignment of the highway or by altering the topography between the highway traffic noise source and the receptor; or,
o The addition of a through-traffic lane(s). This includes the addition of a through-traffic lane that functions as an High-Occupancy Vehicle lane, High-Occupancy Toll lane, bus lane, or truck climbing lane; or,
o The addition of an auxiliary lane, except for when the auxiliary lane is a turn lane; or, o The addition or relocation of interchange lanes or ramps added to a quadrant to complete an existing partial interchange; or,
o Restriping existing pavement for the purpose of adding a through-traffic lane or an auxiliary lane; or,
o The addition of a new or substantial alteration of a weigh station, rest stop, ride-share lot or toll plaza; or,
o If a project is determined to be a Type I project under this definition then the entire project area as defined in the environmental document is a Type I project.

Based on the details described above, implementation of the proposed Project would not increase vehicle volume on local roadways. Therefore, no impacts will occur pertaining to project‐related traffic noise impacts on off‐site sensitive receptors would occur. No mitigation measures are required. b. Result in generation of excessive groundborne vibration or groundborne noise levels? Less than Significant Impact. The vibration damage potential threshold criteria for old buildings, older residential structures, and modern industrial buildings is 0.25 peak particle velocity (PPV) (inches per second [in/sec]), 0.3 PPV (in/sec), 0.5 PPV (in/sec), respectively. In addition, the vibration annoyance potential criteria for continuous/frequent intermittent sources from the same manual. The vibration annoyance potential criteria are: barely perceptible at 0.01 PPV (in/sec), distinctly perceptible at 0.04 PPV (in/sec), strongly perceptible at 0.1 PPV (in/sec), and severe at 0.4 PPV (in/sec). Project construction is expected to use a large bulldozer and loaded truck, which would generate ground-borne vibration levels of 0.089 PPV (in/sec) and 0.076 PPV (in/sec), respectively, when measured at 25 feet. Vibration intensive construction equipment such as pile drivers, jackhammers, or vibratory rollers will not be used during Project construction.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 70 The distance to the nearest buildings for vibration impact analysis is measured between the nearest off‐ site buildings and the Project boundary (assuming the construction equipment would be used at or near the Project boundary) because vibration impacts normally occur within the buildings. Table 3.13.B:

Vibration Source Amplitudes for Construction Equipment shows the PPV and vibration velocity decibels (VdB) values at a distance of 25 feet from the construction vibration source. As shown in Table 3.13.B, bulldozers and loaded trucks would generate a groundborne vibration level of 87 and 86 VdB, respectively, when measured at a distance of 25 feet, based on the Transit Noise and Vibration Impact Assessment Manual.

Table 3.13.C: Summary of Construction Vibration Levels lists the projected vibration level from various construction equipment expected to be used on the Project site to the nearest buildings in the Project vicinity. For typical construction activity, the equipment with the highest vibration generation potential is the large bulldozer, which would generate 87 VdB at 25 feet. The closest residential building to the south is approximately 100 feet from the project construction boundary. As shown in Table 3.13.C, the closest single‐family residence at 90 feet from the project construction boundary would experience vibration levels of up to 69 VdB (0.011 PPV in/sec). All other residences are farther than 100 feet from the project construction boundary and would experience lower vibration levels.

The nearest industrial building, residential building is located 15 feet, 90 feet, and 25 feet, respectively, from the Project site and would experience vibration levels of up to 0.191 PPV (inches/second), 0.013 PPV (inches/second), and 0.089 PPV (inches/second), respectively. Other industrial buildings in the Project area are farther away and would experience lower vibration levels that would not exceed community annoyance threshold and damage threshold. These vibration levels would range from barely perceptible to strongly perceptible, which may result in community annoyance. However, these vibration levels would not exceed the damage potential threshold criteria for old buildings, old residential structures, and modern industrial buildings at 0.25 PPV (inches/second), 0.3 PPV (inches/second), and 0.5 PPV (inches/second), respectively. Therefore, impacts pertaining to construction vibration would be less than significant and no vibration mitigation measures are required.

Long-Term Operational Vibration. Once developed, the Project would not generate vibration. No impact would occur and no mitigation measures are required.

For a project located within the vicinity of a private airstrip or an airport land use plan or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project are to excessive noise levels? No Impact. There are no private airstrips located within the vicinity of the Project site. The Project is beyond the 65 dBA Community Noise Equivalent Level impact zone from San Bernardino International Airport based on the Airport Layout Plan Narrative Report for San Bernardino International Airport, 29 and
beyond the 55 dBA Community Noise Equivalent Level noise contour of both Flabob Airport and Riverside Municipal Airport based on the Riverside County Airport Land Use Compatibility Plan. 30 Therefore, the
Project would not expose people residing or working in the project area to excessive noise levels and no impact would occur. No mitigation is required.

a. Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
No Impact. The proposed Project is a transportation improvement that will include the removal of the Barton Road Bridge over the abandoned UPRR corridor straddling the City of Colton and City of Grand Terrace boundary line. Fill and a new portion of Barton Road will be developed to replace the removed bridge. Additionally, sidewalks and Class II bicycle lanes will be added for pedestrian and bicyclist connectivity as part of the Project. The Project will employ construction workers during construction of the site; however, these positions would likely be filled by individuals local to the area. The Project also does not include any significant infrastructure improvements or the significant extension of roads (as Barton Road already exists) that could indirectly induce growth in either City. Therefore, the proposed Project will not directly or indirectly cause population growth. No impact would occur and no mitigation is required.
b. Displace substantial amounts of people or housing, necessitating the construction of replacement housing elsewhere?
No Impact. The proposed Project will be implemented on Barton Road. A sliver portion of parcel 0275- 223-16-0000 (located in Grand Terrace) will be acquired by the proposed Project. This parcel is zoned as Restricted Manufacturing and is not occupied by housing. As such, implementation of the proposed Project would not displace substantial amounts of people or housing, necessitating the construction of replacement housing elsewhere. Therefore, no impact would occur and no mitigation is required.

Fire Protection
Less than Significant Impact. The City of Colton Fire Department provides fire suppression and emergency medical services to the City. Fire Station 213 located approximately 1.28 miles to the north at 1100 South La Cadena Drive is the nearest Colton Fire Station that will serve the Project site. Station 213 is staffed by a captain, engineer, and firefighter/paramedic and is the Heavy Rescue Unit headquarters. The station is equipped with one fire engine.31
The City of Grand Terrace is within the service area of the San Bernardino County Fire Department for fire and rescue services.32 Fire Station 23 is located at 22582 City Center Court in Grand Terrace and is approximately 1 mile east of the Project site.

San Bernardino County Fire Station 23 and Colton Fire Department Station 213 is within an estimated three-minute travel time to the Project site. Through compliance with California Vehicle Code 21806(A)(1), which requires all vehicles to yield to emergency vehicles, travel time between the nearest fire station and the Project site is expected to remain approximately three minutes. The National Fire Protection Association maintains a four-minute response time standard for first responders, 90 percent of the time, and the Project site’s proximity to San Bernardino County Fire Station 23 and Colton Fire Department Station 213 would not preclude the Grand Terrace Fire Department’s or City of Colton Fire Department’s ability to meet the National Fire Protection Association standard. Additionally, both cities maintain mutual aid agreements with surrounding cities, which allow for the services of nearby fire departments to assist both cities during major emergencies. Therefore, the Project would not conflict with the City’s response time standard.

During construction, Barton Road will be closed to traffic between Terrace Avenue and Grand Terrace Avenue during the duration of construction activities. As a condition of approval, the construction contractor retained by the Project proponent will be required to develop a road closure detour plan

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 74 (detour plan) to enable motorists to travel safely around the closed portion of Barton Road and to allow fire department and emergency service access to the Project area. The proposed detour will route traffic around the construction zone on Barton Road via S. Terrace Avenue, De Berry Street, and S. La Crosse Avenue. The detour plan will be provided to the Colton Fire Department and San Bernardino Fire Department in order for them to plan emergency routes to the Project site and surrounding uses in the event of an emergency. Once the Project is completed, fire department service would not increase as the Project is not growth inducing. Because of the variety and proximity of existing fire protection services, no new or expanded fire stations are required to service the Project site during construction and operational activities. A less than significant impact would occur and no mitigation is required.

Police Protection
Less than Significant Impact. The City of Colton Police Department will serve the Project site. The Police Department headquarters is in the City’s civic center located at 650 North La Cadena Drive, approximately 3 miles north of the Project site.33 The City of Grand Terrace contracts with the San Bernardino County Sheriff-Coroner Department.
34 The Project site is located two miles to the northwest of the City crime prevention headquarters, with an estimated three-minute travel time to the Project site.

Similar to fire protection services, the Project site is already within the service area of the Colton Police Department and San Bernardino County Sheriff and would continue to be served by both departments upon Project implementation. Compliance with California Vehicle Code 21806(A)(1), which requires all vehicles to yield to emergency vehicles, would ensure response times to the Project site are not significantly altered.

As a condition of approval, the construction contractor retained by the Project proponent will be required to develop a road closure detour plan (detour plan) to enable continuous access to the site and surrounding uses during Project construction. This detour plan will be shared with the Colton Police Department and San Bernardino County Sheriff’s Department to ensure that both can plan proper routing to the Project area during associated road closures. Any construction equipment left at staging areas will be properly secured to reduce vandalism or theft during construction activities. This will reduce calls to service to the Project site from the Colton Police Department and San Bernardino County Sherriff’s Department during the construction period. Once completed, calls for service to the site from local law enforcement is anticipated to be the same as under existing conditions. Since the proposed Project would not generate a substantial increase in population, any incremental increase in demand for police services would not create the need for new or altered police facilities. Therefore, impacts would be less than significant and no mitigation is required.

Schools
No Impact. While the Project site is located within the Colton Joint Unified School District, because the Project does not include a residential component, no direct increase in the local student population would occur. Employment opportunities resulting from the construction of the proposed Projectislikely to be filled by existing local residents; therefore, no significant indirect increase in the local student population would occur and there would be no impact on schools. No mitigation is required.

Less than Significant Impact. Both the City of Colton and the City of Grand Terrace General Plans identify intersection thresholds of significance. These thresholds use level of service (LOS), a ratio of traffic volume to roadway capacity. Levels of service are defined using the letter grades A through F, in which LOS A35 represents the least amount of traffic congestion and LOS F36 the most. Both cities use LOS D as the minimum level of service criteria for intersections. Any intersection operating at LOS E or F is considered to be unacceptable.

A Project-specific Traffic Study Report (TSR) (Appendix G) was prepared to assess potential circulation impacts associated with the proposed Project. The TSR was conducted to conform to analysis standards and parameters established by the City of Colton. The City of Colton guidelines prescribe the use of the Highway Capacity Manual methodology in determining the level of service for signalized intersections.

The TSR summarized the analysis for the existing year 2019, 2023, and 2045 design year under two conditions, including: (1) Existing, (2) Opening Year, and (3) Buildout Year).

35 LOS A is defined as a delay per vehicle of ≤ 10 seconds for unsignalized intersection and ≤ 10 seconds for signalized intersection. 36 LOS F is defined as a delay per vehicle of > 50 seconds for unsignalized intersection and > 80 seconds for signalized intersection.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 78 Streets in the site vicinity that will be affected by the proposed Project include La Cadena Drive, Terrace Avenue, Grand Terrace Road, and Barton Road. The following provides a summarization of the existing conditions of the roads in the vicinity of the Project site:

La Cadena Drive. La Cadena Drive is a north-south, four-lane roadway divided by a raised median. The posted speed limit in the study area is 50 mph. La Cadena Drive is the only Divided Major Highway in the City of Grand Terrace and runs along the boundary of the two cities. A Divided Major Highway, such as La Cadena Drive, consists of a 120-foot right-of-way with a divided 64-foot improved section and a raised median. La Cadena Drive connects the City of Grand Terrace to the City of Colton to the north and connects to the City of Riverside to the south. According to the Land Use Plans of the Cities of Colton and Grand Terrace, the land uses along La Cadena Drive are light industrial and industrial park zones, respectively.

Terrace Avenue. Terrace Avenue is a north-south, two-lane roadway. It is classified as a Local Street in the Cities of Colton and Grand Terrace. The speed limit for this road in the Project area is 25 mph. Terrace Avenue is divided into two street segments by Barton Road where the north segment extends along the boundary of City of Grand Terrace and City of Colton, and the south segment continues into the City of Colton. This street provides direct access to residential neighborhoods. With a 60-foot right-of-way and a 36-foot improved section, local streets have direct residential lots fronting onto them and are the standard street category within residential neighborhoods. According to both City of Colton and City of Grand Terrace Land Use Plans, the land uses in the vicinity of the Project along Terrace Avenue are light industrial and industrial park zones, respectively.

Grand Terrace Road. Grand Terrace Road is a north-south, two-lane roadway. It is located approximately 550 feet east of the Project site. The posted speed limit of the road in the study area is 25 mph. Grand Terrace Road is one of the collector streets in the City of Grand Terrace and extends partially into the City of Colton and along the boundaries of the two cities. With a 66-foot right-of-way and a 44-foot improved section, this category of roadway connects local traffic with residential neighborhoods and the arterial highway network. According to the Land Use Plans of the two cities, the land uses along Grand Terrace Road are medium density residential and industrial zones.

Barton Road. Barton Road is an east-west, four-lane roadway. The posted speed limit is 40 mph. This is one of the major highways in the City of Grand Terrace and it provides service to non-local commuters along Interstate 215 (I-215) as well as local access to the public. Major highways have a 100-foot right-ofway with a 72-foot improved section. The roadway classification is characterized with four travel lanes, minimal curb cuts, and signalized intersections. Barton Road also provides direct access to the regional freeway I-215 and commercial corridors; it runs through the City of Grand Terrace. Barton Road continues into the City of Colton with most of its land uses designated as general commercial, industrial, and lowdensity residential zones. Barton Road between South La Cadena Drive and Grand Terrace Road has a 2019 average daily traffic (ADT) volume of 7,292 vehicles.

The study area for the TSR encompasses the above identified road segments and four intersections in the Project vicinity. The intersections include: La Cadena Drive and Barton Road; North Leg of Terrace Avenue and Barton Road; South Leg of Terrace Avenue and Barton Road; and Grand Terrace Road and Barton Road. The four intersections, as of 2019, operated at LOS B or LOS C conditions during AM and PM Peak Hours. Table 3.17.A: Opening Year (2023) and Horizon Year (2045) Intersection LOS summarizes the delay time and LOS under each of these conditions at the four study intersections.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 79 As shown in Table 3.17.A, the Barton Road/South Leg Terrace Road intersection will operate at unacceptable LOS F conditions during the PM peak hours in the Horizon Year (2045) and the Barton Road/La Cadena Drive intersection will operate at unacceptable LOS F conditions during the AM peak hours in the Horizon Year (2045). This is due to the anticipated build-out of the Cities of Colton and Grand Terrace and is not directly caused by the proposed Project.

Notes: TWSC = Two-way stop-controlled. Bolded LOS = Unacceptable LOS Barton Road, during Project construction, will be closed, requiring a detour to be implemented. The detour is anticipated to generate some delays in the traffic flow around the proposed Project. The detour will route traffic around the construction zone on Barton Road via S. Terrace Avenue, De Berry Street, and S. La Crosse Avenue. Analysis presented in the TSR determined this detour would not generate major queuing spill back on La Cadena Drive or at Grand Terrace Boulevard. The delay is not significantly higher and both of these intersections will continue to operate at acceptable LOS during Project construction.

The closure of Barton Road during Project construction will, therefore, not contribute to substantial degradation of intersection LOS.

The proposed Project will include new sidewalks and a Class II bicycle lane along Barton Road in the area where the Barton Road Bridge over the UPRR corridor will be removed. These additions associated with the proposed Project will result in a benefit to the Cities of Colton and Grand Terrace bicycle and pedestrian facilities by creating better connectivity for these alternative modes of transportation.

Implementation of the proposed Project will not conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities. Impacts will be less than significant and no mitigation measures are required. b. Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)? No Impact. CEQA Guidelines Section 15064.3, subdivision (b) establishes “vehicle miles traveled” (VMT) criteria in lieu of LOS for analyzing transportation impacts and was signed into law as Senate Bill (SB) 743 in 2013. Regulatory changes to the CEQA Guidelines that implement SB 743 were approved by the Office of Planning and Research on December 28, 2018. However, lead agencies had until July 1, 2020, which is the statewide implementation date, to opt-in use of the new VMT metric. In cases where lead agencies use LOS for analyzing transportation impacts, they may continue to do so until July 1, 2020.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 80 In June 2020, the City of Colton published TO#234 City of Colton VMT (Vehicle Miles Traveled) Guidelines for the City of Colton, California which provides the City of Colton VMT methodology for various projects by analyzing the VMT per capita, employee, and/or per service population. In concurrence with the California Office of Planning and Research Guidelines, transportation projects in the City of Colton that will not significantly impact the amount of vehicle travel can be excluded from VMT analysis.37 The proposed Project includes removal of the Barton Road Bridge over the UPRR corridor, replacing the bridge with fill and a new roadbed to connect to Barton Road, new sidewalks, and new Class II bicycle lanes. The Project will not generate more vehicle volume above the existing volume along Barton Road nor will it generate more vehicle miles traveled compared to existing conditions. The proposed Project will therefore not conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b). No impact will occur and no mitigation measures are required.
c. Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less than Significant Impact. The proposed Project is being implemented as the Barton Road Bridge was originally built in 1936 over the UPRR corridor and is now structurally unsound and does not provide adequate, safe, pedestrian or bicycle access along Barton Road. The design of the existing Barton Road Bridge does not account for seismic loading, which is required for public safety in California due to the high seismic activity in the state. If the proposed Project is not implemented, it would continue to present a hazard to the public (motorists, pedestrians, bicyclists) traveling along Barton Road between South Terrace Avenue and Grand Terrace Road. The proposed Project would remove the structurally unsound bridge and replace it with fill and road that would replenish the Barton Road connection where the bridge used to be located. The proposed Project will also implement sidewalks and a Class II bicycle lane designed to City of Colton and City of Grand Terrace standards. This design feature will improve safe travel for pedestrians and bicyclists along Barton Road between South Terrace Avenue and Grand Terrace Road.

Overall, the proposed Project would not substantially increase hazards due to a geometric design feature, but would actually improve the overall safety of Barton Road for pedestrians, motorists, and bicyclists between South Terrace Avenue and Grand Terrace Road. Impacts will be less than significant. No mitigation is required.
d. Result in inadequate emergency access?
Less than Significant Impact. Roadway facilities with regional access typically serve as evacuation routes in the event of an emergency. The City of Grand Terrace General Plan Public Health38 and Safety Element and the City of Colton General Plan Safety Element39 identifies Barton Road and La Cadena Avenue as major evacuation routes. Specific evacuation routes depend upon the type of emergency and its location, but La Cadena Avenue are within 1,000 feet of the proposed Project and the proposed Project is on Barton Road.

During construction of the proposed Project, Barton Road will be temporarily closed between Terrace Avenue and Grand Terrace Avenue. As a condition of approval for the Project, a detour plan will be prepared and distributed to emergency service, fire department, and police department staff that provides service to the Project site and surrounding uses. As part of the detour plan, signs will be installed

a. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? The Historic Property Survey Report prepared for the proposed Project indicated that there have been 17 cultural resource studies previously conducted within one mile of the Project site, two of which included parts of the Project site. A linear cultural resource transects the Project site (36-006101, the historic period UPRR route) and 25 additional cultural resources have been documented within one mile of the Project site. The additional cultural resources include prehistoric (habitation site, rock shelters, milling features, and artifactscatters) and historic period (rock shelter) archaeological resources, along with historic period utilities, railroads, water conveyance systems, a residence, school, and bridge. The segment of UPRR route transecting the Project site was evaluated in 2009 as not eligible for the National Register either individually or as contributing segments to the overall alignment. The Barton Road Bridge is listed in the California Historical Significance Local Agency Bridge List as a Category 5 Bridge; however, it is not eligible for the National Register. With the exception of the Barton Road Bridge, none of the resources identified is listed in any of the registers, directories, or inventories. The nearest prehistoric resource (a habitation site and artifact scatter) was documented approximately 0.57 mile north of the proposed Project site.

Additional previous research indicated two additional built environment resources (21842 Grand Terrace Road and 21892 Grand Terrace Road); however, these two historic period residences were evaluated as not eligible for the National Register and concurred with by the State Historic Preservation Office in 2011.

Due to the minimal results of the records search and the survey conducted for the proposed Project, along with the average depth of road subgrades (3+ feet) and severe disturbance of urban road right-of-way, there is a small potential for intact subsurface cultural deposits being found during Project construction

In applying the criteria set forth in subdivision (c) of Public Resource Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe? Chapter 532, Statutes of 2014 (i.e., AB 42), requires Lead Agencies evaluate a project’s potential impact to “tribal cultural resources.” Such resources include “[s]ites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American Tribe that are eligible for inclusion in the California Register of Historical Resources or included in a local register of historical resources.” AB 52 also gives Lead Agencies the discretion to determine, supported by substantial evidence, whether a resource qualifies as a “tribal cultural resource.”
Per AB 52 (specifically PRC 21080.3.1), Native American consultation is required upon request by a California Native American tribe that has previously requested that the City provide it with notice of such projects. Pursuant to provisions of AB 52, the City contacted (November 11, 2020) the following Native American groups:
• Agua Caliente Band of Cahuilla Indians;
• Augustine Band Cahuilla Band of Indians;
• Cabazon Band of Mission Indians;

The Augustine Band of Cahuilla Indians stated in their response (November 16, 2020), “At this time, we are unaware of specific cultural resources that may be affected by the proposed project.” The tribe requested to be notified in the event any cultural material is discovered during project construction.

The Cabazon Band of Mission Indians stated in their response (November 18, 2020), “There is no presence of Native American resources that may be impacted by your future project regarding the replacement of the existing two-lane bridge on Barton Road and road construction project in Colton, CA.” The San Manuel Band of Mission Indians (SMBMI) stated in their response (November 17, 2020), “The proposed project area exists within Serrano ancestral territory and, therefore, is of interest to the Tribe.

However, due to the disturbance, nature, and location of the proposed project, and given the CRM Department’s present state of knowledge, SMBMI does not have any concerns with the project’s implementation, as planned, at this time.”
No other Native American groups responded to the City’s invitation to consult on the project.

The SMBMI requested the following mitigation to address potential future impacts relative to Native American cultural resources:

Mitigation Measure TCR-1: In the event that cultural resources are discovered during project activities, all work in the immediate vicinity of the find (within a 60-foot buffer) shall cease and a qualified archaeologist meeting Secretary of Interior standards shall be hired to assess the find. Work on the other portions of the project outside of the buffered area may continue during this assessment period.

Additionally, the San Manuel Band of Mission Indians Cultural Resources Department (SMBMI) shall be contacted, as detailed within TCR-2, regarding any pre-contact and/or historic-era finds and be provided information after the archaeologist makes his/her initial assessment of the nature of the find, so as to provide Tribal input with regard to significance and treatment.

If significant pre-contact and/or historic-era cultural resources, as defined by CEQA (as amended, 2015), are discovered and avoidance cannot be ensured, the archaeologist shall develop a Monitoring and Treatment Plan, the drafts of which shall be provided to SMBMI for review and comment, as detailed within TCR-2. The archaeologist shall monitor the remainder of the project and implement the Plan accordingly.

If human remains or funerary objects are encountered during any activities associated with the project, work in the immediate vicinity (within a 100-foot buffer of the find) shall cease and the County Coroner shall be contacted pursuant to State Health and Safety Code §7050.5 and that code enforced for the duration of the Project.

Mitigation Measure TCR-2: The San Manuel Band of Mission Indians Cultural Resources Department (SMBMI) shall be contacted if any pre-contact and/or historic-era cultural resource(s) are discovered during project implementation and be provided information regarding the nature of the find, so as to provide Tribal input with regard to significance and treatment.

Should the find be deemed significant, as defined by CEQA (as amended, 2015), a cultural resources Monitoring and Treatment Plan shall be created by the archaeologist, in coordination with SMBMI, and all subsequent finds shall be subject to this Plan. Should SMBMI elect to place a monitor on site,

The City of Colton will coordinate directly with the utility providers to ensure relocation of facilities adequately occurs and no additional environmental affects above and beyond those analyzed in this document occurs.

The approval of drainage features/improvements occurs through the City’s plan check process. As part of this process, all project-related drainage features will be required to meet the City’s Public Works Department and Santa Ana RWQCB standards. On-site project-related drainage features will be designed,

There would be no significant environmental effects specifically related to the relocation of utility facilities that are not encompassed within the Project’s construction and operational footprint, and therefore already identified, disclosed, and subject to all applicable mitigation measures, as well as local, State, and federal regulations, as part of this Initial Study. Therefore, impacts related to relocation of utilities would be less than significant. No additional mitigation is required. b. Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years? Less than Significant Impact. The Project site is served by the RHWC. According to the SBVR 2015 UWMP, the RHWC relies on groundwater from five separate groundwater basins. The RHWC actual per capita water use per day in 2015 was 166 gallons.40 The proposed Project will require non-potable water during construction activities for dust suppression. The amount of water that will be required during the 14 month construction period will be minimal and will more than likely be trucked in and stored onsite or obtained through hooking up of nearby existing fire hydrants. Once the Project is complete, water use will not be required. Comparing historically low conditions to demand projections, the RHWC has adequate water supplies available to meet projected demands should a multiple-dry year period occur. Also, the RHWC has ample water supply to serve the Project during the 14-month construction period. Impacts would be less than significant and no mitigation is required. c. Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Less than Significant Impact. The proposed Project includes removal of the Barton Road Bridge over the abandoned UPRR corridor, installation of fill and new roadbed in place of the bridge, new sidewalks and new Class II bicycle lanes, to provide safe connectivity between La Cadena and the Barton Road/I-215 interchange and efficient access between the Cities of Colton and Grand Terrace. During Project construction, portable restrooms will be set up for construction workers. The portable restrooms will be emptied as required and its contents will be transported to local wastewater facilities for treatment.

Construction of the proposed Project will minimally increase the amount of wastewater generated that will need to be treated at local facilities. Once complete, the proposed Project will not generate wastewater that will need to be treated at local facilities. The wastewater treatment provider will have adequate capacity to serve the Project during its construction period (14 months). Impacts will be less than significant and no mitigation measures are required. d. Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Less than Significant Impact. Solid waste collection and disposal within the City are provided by Colton Disposal. There are a number of active landfills that currently serve the City of Colton; however, solid waste is first transported to the CR&R Inland Regional Material Recovery Facility located at 2059 E. Streel Road in Colton. The solid waste is sorted at this facility and non-recyclable waste is then transported to active landfills serving the City of Colton for appropriate disposal. The proposed Project will only generate

The construction debris will be transported to the Inland Regional Material Recovery Facility where it will be sorted for recycling purposes (as applicable) and then transported to the appropriate landfill. The amount of construction debris that will be generated by the proposed Project is estimated to be minimal and will not be enough to exceed the capacity of local active landfills or transfer facilities. Therefore, impacts associated with excessive generation of solid waste would be less than significant. No mitigation is required. e. Comply with federal, State, and local management reduction statutes and regulations related to solid waste?
Less than Significant Impact. The City of Colton requires all projects to adhere to all source reduction programs set forth for the disposal of solid waste, including construction demolition materials. The City General Plan sets out goals and policies to provide for an efficient and environmentally sound solid waste collection, recycling, and disposal system. The proposed Project would adhere to all applicable local, State, and federal solid waste disposal standards. Therefore, impacts associated with solid waste disposal regulations would be less than significant. No mitigation is required.

Less than Significant Impact. The Project site is currently occupied by Barton Road and the Barton Road Bridge spanning the abandoned UPRR corridor in an urban area straddling the Colton and Grand Terrace city boundary line. Small areas of vegetation exist on land within the site that is not occupied by urban uses. Some of these vegetated areas will be replaced by roadway features with implementation of the proposed Project. The Project site is relatively flat. The proposed Project would not exacerbate wildfire risks due to slope, prevailing winds, or other factors and would not expose the traveling public to pollutant concentrations from a wildfire or uncontrolled spread of a wildfire. Impacts would be less than significant and no mitigation is required.
c. Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may result in temporary or ongoing impacts to the environment?
Less than Significant Impact. The proposed Project will require the removal and reconstruction of the drainage outlet west of Grand Terrace Avenue and construction of a drainage culvert across Barton Road in the vicinity of the abandoned UPRR corridor. The Project will also require relocation of the Riverside Highland Water Company line, the City of Colton waterline, fiber optic cables, and a gas line in the existing bridge and roadway and relocation of overheard telephone lines along the north side of Barton Road. All of these relocation/reconstruction requirements will occur with oversight from owners of the facilities or from public works departments of Colton and Grand Terrace as applicable. These features associated with the proposed Project are not anticipated to result in temporary or ongoing impacts to the environment.

Impacts would be less than significant and no mitigation measures are required. d. Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes?

Less than Significant with Mitigation Incorporated. The proposed Project’s impacts to biological resources and cultural resources were analyzed in this Initial Study, and all direct, indirect, and cumulative impacts were determined to have no impact, a less than significant impact, or reduced to a less than significant impact with implementation of mitigation. No endangered or threatened species were identified on the Project site. Development of the proposed Project would not cause fish or wildlife populations to drop below self-sustaining levels or restrict the movement/distribution of a rare or endangered species. The proposed Project would not affect any threatened or endangered species or associated habitat. Potential impacts to roosting bats in palm trees on the site and nesting birds would be mitigated to less than significant levels with implementation of Mitigation Measures BIO-1 and BIO-2.

Development of the proposed Project would not affect known historic, archaeological, or paleontological resources. There are no known unique or cultural values associated with the Project site, nor are known

In the event that undiscovered cultural or archaeological resources are uncovered during Project construction, implementation of Mitigation Measure CUL-1 would ensure impacts are reduced to a less than significant level. Additionally, the Project applicant is required to comply with CCR Section 15064.5(e), California Health and Safety Code Section 7050.5, and PRC Section 5097.98 as a matter of policy in the event human remains are encountered at any time. Furthermore, Mitigation Measures TCR-1 and TCR-2has been identified to address potential impacts if subsurface cultural resources pertaining to Native Americans would be encountered during construction. Implementation of the above identified mitigation measures as well as adherence to regulations governing human remains, would reduce potential impacts to cultural and paleontological resources to less than significant.
b. Have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.)
Less than Significant Impact. The proposed Project has either no impact, a less than significant impact, or a less than significant impact with mitigation incorporated with respect to all environmental issues pursuant to CEQA. Due to the limited scope of direct physical impacts to the environment associated with the proposed Project, the Project’s impacts are primarily project-specific in nature.

The proposed Project is listed in the 2016 financially constrained RTP/SCS Amendment No 2, which was found to conform by SCAG on July 6, 2017, and by the FTA/FHWA on August 1, 2017. On September 6, 2018, SCAG’s Regional Council adopted the 206 RTP/SCS Amendment No. 3 but conformity determination approval from the FHWA is pending. The proposed Project is listed in the 2017 Federal Transportation Improvement Program (FTIP) 17-00 under ID No. SDBSL08. The 2017 FTIP Consistency Amendment 17-18 was approved by SCAG on February 23, 2018, and by FTA/FHWA on March 26, 2018. The design concept and scope on the proposed Project is consistent with the Project description in the 2016 RTP and 2017 FTIP and the “open to traffic” assumptions of the SCAG’s regional emissions analysis.

The proposed Project would not exceed significance thresholds for air-quality impacts during short-term construction-related activities or for operation. As such, standard conditions and/or mitigation measures to reduce air quality impacts are not warranted. Construction and operational noise would not exceed City thresholds; therefore, no standard conditions or mitigation measures are warranted.

The analysis presented in this Initial Study takes into account cumulative effects the proposed Project would have in the Cities of Colton and Grand Terrace. Overall, all impacts described herein have been reduced to a level that is less than significant and the Project’s contribution to cumulative impacts would also be reduced with implementation of site-specific mitigation measures and conditions of approval identified in this document. The proposed Project would have a less than cumulatively considerable impact.
c. Have environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly?
Less than Significant Impact with Mitigation Incorporated. As analyzed throughout this IS/MND, incorporation of mitigation measures and conditions of approval would reduce Project impacts to a level that is less than significant. This document has concluded that the proposed Project would not have environmental effects that will cause direct or indirect substantial adverse effects on human beings.

BARTON ROAD BRIDGE REMOVAL AND ROAD CONSTRUCTION PROJECT 99 5.0 MITIGATION MONITORING AND REPORTING PROGRAM
The Mitigation Monitoring and Reporting Program (MMRP) has been prepared for use in implementing mitigation for the Barton Road Bridge Removal and Road Construction Project.

The program has been prepared in compliance with State law and the Mitigated Negative Declaration (MND) prepared for the Project by the City of Colton.

CEQA requires adoption of a reporting or monitoring program for those measures placed on a project to mitigate or avoid adverse effects on the environment (Public Resource Code Section 21081.6). The law states the reporting or monitoring program shall be designed to ensure compliance during project implementation.

The MMRP contains the following elements:
1) The mitigation measures are recorded with the action and procedure necessary to ensure compliance.

In some instances, one action may be used to verify implementation of several mitigation measures. 2) A procedure for compliance and verification has been outlined for each action necessary. This procedure designates who will take action, what action will be taken and when, and to whom and when compliance will be reported.
3) The program has been designed to be flexible. As monitoring progresses, changes to compliance procedures may be necessary based upon recommendations by those responsible for the program.

As changes are made, new monitoring compliance procedures and records will be developed and incorporated into the program.

This Mitigation Monitoring and Reporting Program includes mitigation identified in the MND.

5.1 MANDATORY FINDINGS OF SIGNIFICANCE
As the Lead Agency, the City is responsible for ensuring full compliance with the mitigation measures adopted for the proposed project. The City will monitor and report on all mitigation activities. Mitigation measures will be implemented at different stages of development throughout the project site. In this regard, the responsibilities for implementation have been assigned to the Applicant, Contractor, or a combination thereof. If during the course of project implementation, any of the mitigation measures identified herein cannot be successfully implemented, the City shall be immediately informed, and the City will then inform any affected responsible agencies. The City, in conjunction with any affected responsible agencies, will then determine if modification to the project is required and/or whether alternative mitigation is appropriate.

5.2 STANDARD CONDITIONS
Standard Conditions are presented in instances where the proposed project would not create a significant impact but would be required to adhere to regulatory requirements in order to ensure impacts do not become significant. Standard Conditions outline compliance with various federal, State, and/or local acts, laws, rules, regulations, municipal codes, etc.

MITIGATION MEASURES

AIR QUALITY
Mitigation Measure AQ-1: Prior to the
commencement of any construction activities, the
construction contractor shall submit a Construction
Emission Control Plan for review and approval to
the City of Colton Department of Public Works,
which shall be implemented during construction.

The Construction Emissions Control Plan shall
comply with federal, State, and local regulations as
specified in the measures below:
• The contractor shall adhere to the Caltrans
Standard Specifications for Construction,
Sections 14.9-01, 14.9-02, 14.9-03, 18-1.02C,
and 18-1.03 (or Greenbook equivalent
specifications). Section 14-9-02 specifically
requires compliance by the contractor with all
applicable laws and regulations related to air
quality, including air pollution control district
and air quality management district
regulations and local ordinances.
• Water or a dust palliative shall be applied to
the site and equipment as often as necessary
to control fugitive dust emissions. Fugitive
emissions generally must meet a “no visible
dust” criterion either at the point of emissions
or at the right-of-way line depending on local
regulations in compliance with the SCAQMD
Rule 403 (Fugitive Dust).

BIOLOGICAL RESOURCES
Mitigation Measure BIO-1: Prior to construction,
an approved bat biologist shall be retained by the
Project proponent to conduct a bat assessment
survey to determine the presence or absence of bat
species that may occur within the Project limits.

Should the presence of bat species be determined
during this assessment, the following measures
shall be implemented:
• Nighttime exit counts and acoustic surveys
shall be performed by a qualified bat biologist
at all structures and palm trees that may be
subject to project-related impacts. These
surveys shall be performed during the
recognized bat maternity season (April 1
through August 31, but preferably in June or
July) and as far in advance of construction as

possible in order to provide adequate time for
mitigation planning.
• Construction activities at structures housing
maternity colonies shall be coordinated with
an approved bat biologist and CDFW.
• If direct impacts to bat-roosting habitat are
anticipated, humane evictions and exclusions
of roosting bats shall be performed under the
supervision of an approved bat biologist after
August 31 in the fall (September or October)
prior to any work activities that would result in
direct impacts or direct mortality to roosting
bats. This action shall be performed in
coordination with the CDFW. To avoid
potential mortality of flightless juvenile bats,
evictions and exclusions of bats cannot be
performed during the maternity season (April
1 through August 31). Winter months are also
inappropriate for bat eviction because not all
individuals in a roost will emerge on any given
night. In addition, long-distance movements to
other roost sites are more difficult during the
winter when prey availability is scarce,
resulting in high mortality rates of evicted bats.
• Alternative bat-roosting habitat structures
shall be installed on the structures prior to the
eviction/exclusion of bats from that structure.

The design, numbers, and locations of these
roost structures shall be determined in
consultation with an approved bat biologist.

• If permanent, direct impacts to bat-roosting
habitat are anticipated and a humane

permanent roosting habitat shall be provided
to ensure no net loss of bat-roosting habitat.

This action shall be coordinated with the
CDFW, and locations of these roost structures

• The loss of a night roost can negatively affect
the use of a foraging area, and consequently
may result in reduced fecundity in species that
are already slow to reproduce. If night roosting
is confirmed at any of the structures within the
proposed Project area, the following measure
to minimize potential impacts to nightroosting and foraging bats shall be implemented:
o At structures where night roosting is
suspected or confirmed, work shall be
limited to the daylight hours to the
greatest extent feasible to avoid potential
disruption of foraging. If night work
cannot be avoided, night lighting shall be
focused only on the area of direct work,
airspace access to and from the roost
features of the structure shall not be
obstructed, and light spillover into the

Mitigation Measure BIO-2: If feasible, project
construction and any vegetation removal should
begin outside of bird breeding season (typically
between September 1 and February 14). In the
event that project construction cannot be
conducted outside the bird breeding season, and
vegetation will be removed, focused surveys shall
be conducted by a qualified biologist prior to
ground-disturbing activities. Should nesting birds
be found, an exclusionary buffer shall be
established by a qualified biologist. The buffer may
be up to 500 feet in diameter depending on the
species of nesting bird found. This buffer shall be
clearly marked in the field by construction
personnel under guidance of the qualified biologist,
and construction or clearing shall not be conducted
within this zone until the qualified biologist
determines that the young have fledged or the nest
is no longer active. Nesting bird habitat within the
BSA shall be resurveyed during bird breeding
season if there is a lapse in construction activities
longer than seven days.

situation, consult with agencies as appropriate, and
make recommendations for the treatment of the
discovery. The City of Colton and Grand Terrace
shall also be notified. Project personnel shall not
collect or move any archaeological materials
uncovered by construction activities.

Any adverse impacts to the finds shall be avoided
by Project construction activities. If avoidance is
not feasible, the archaeological deposits shall be
evaluated to determine if they qualify as a historical
resource or unique archaeological resource, or as
historic property. If the deposits do not so qualify,
avoidance is not necessary. If the deposits do so
qualify, adverse impacts on the deposits shall be
avoided, or such impacts shall be mitigated.

Mitigation may consist of, but is not limited to,
recovery and analysis of the archaeological deposit;
recording the resource; preparing a report of
findings; and accessioning recovered
archaeological materials at an appropriate curation
facility. Educational public outreach may also be
appropriate. Upon completion of the assessment,
the archaeologist shall prepare a report
documenting the methods and results, and provide
recommendations for the treatment of the
archaeological deposits discovered. The report
shall be submitted to the City of Colton and City of

HAZARDS AND HAZARDOUS MATERIALS
Mitigation Measure HAZ-1: Prior to the
commencement of Project construction, a soil
management plan shall be developed to identify
the appropriate and applicable procedures to be
followed with respect to worker health and safety
during future excavations and construction
activities in areas of potential soil impact.

The soil management plan shall detail the
appropriate and applicable local, State, and federal
regulations regarding the proper characterization,
treatment, and/or disposal of any impacted soils
encountered during excavation or construction
activities. Any impacted soil encountered shall be
appropriately handled pursuant to the project soil

TRIBAL CULTURAL RESOURCES
Mitigation Measure TCR-1: In the event that
cultural resources are discovered during project
activities, all work in the immediate vicinity of the
find (within a 60-foot buffer) shall cease and a
qualified archaeologist meeting Secretary of
Interior standards shall be hired to assess the find.

Work on the other portions of the project outside
of the buffered area may continue during this
assessment period. Additionally, the San Manuel
Band of Mission Indians Cultural Resources
Department (SMBMI) shall be contacted, as
detailed within TCR-2, regarding any pre-contact
and/or historic-era finds and be provided
information after the archaeologist makes his/her
initial assessment of the nature of the find, so as to
provide Tribal input with regards to significance
and treatment.

If significant pre-contact and/or historic-era
cultural resources, as defined by CEQA (as
amended, 2015), are discovered and avoidance
cannot be ensured, the archaeologist shall develop
a Monitoring and Treatment Plan, the drafts of
which shall be provided to SMBMI for review and
comment, as detailed within TCR-2. The
archaeologist shall monitor the remainder of the
project and implement the Plan accordingly.

1. Proposed Project Description
1 1. Proposed Project Description

1.1 Introduction
The Cities of Grand Terrace and Colton, in coordination with the California Department of Transportation (Caltrans) District 8, propose to replace the existing two lane bridge on Barton Road over the Union Pacific Railroad tracks (UPRR) between the two cities (proposed Project). The proposed Project will fill the area over the abandoned railroad tracks with on-site earth and build a new two-lane asphalt road at-grade level as shown in Figures 1-1 and 1-2. The new at-grade asphalt road will include pedestrian sidewalks and Class II bicycle lanes in each direction. The purpose of the proposed Project is to reduce congestion and improve pedestrian and bicyclist safety on Barton Road between Terrace Avenue and Grand Terrace Avenue. There will be minor seismic activity contribution during bridge removal. The City of Colton will be the implementing lead agency for design and construction.

The proposed Project will include paving a 1,100-foot long section of Barton Road, between Terrace and Grand Terrace Avenues. East of the Project, westbound Barton Road provides two lanes that are reduced to one lane approximately 400 feet from the end of the Project boundary. The roadway will accommodate a 6-foot wide sidewalk on the north and south sides of Barton Road, an 8-foot wide striped Class II bicycle lane on each side of the roadway, and two 14-foot wide travel lanes. These lane configurations transition to join existing improvements west of Grand Terrace Avenue.

The City of Colton is the lead agency under the California Environmental Quality Act (CEQA).

Because the Project would use federal funds, Caltrans District 8 is the lead agency under the National Environmental Policy Act (NEPA), as assigned by the Federal Highway Administration (FHWA) through NEPA delegation.

1.2 Location and Background
Within the Project limits, Barton Road is bordered by a single-family residence, commercial businesses, a distribution warehouse, a construction storage yard, and a business park. The Project will remove the 25-foot wide Barton Road Bridge, originally built in 1936, as it has been determined to be structurally unsound and does not provide adequate pedestrian or bicycle access. The removal of the Barton Road Bridge (State Bridge No. 54C0379) will allow needed Class II bicycle lanes meeting the requirements of both the Cities of Grand Terrace and Colton.

The Cities, in association with Caltrans, propose to widen the area of the newly built roadway on either side of the Barton Road Bridge. The existing pedestrian path on the bridge has been closed to pedestrians due to safety concerns. The UPRR tracks no longer exist underneath the bridge and, since the bridge is being removed, the areas underneath the bridge will be filled in with earth to

1. Proposed Project Description
7 make the new at-grade level roadway. The newly widened roadway will include an 8-foot wide bicycle path and 6-foot wide pedestrian sidewalk on both sides. The proposed Project is listed in the financially constrained list of projects in the 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) under the Federal Highway Bridge Program (HBP) ID# 1056 (see Appendix A). The 2016 RTP was approved by the Regional Council of the Southern California Association of Governments (SCAG) on April 7, 2016, with ongoing amendments as needed, with Amendment No. 2 adopted on July 6, 2017.

The proposed Project is listed in the 2016 financially constrained RTP/SCS Amendment No. 2, which was found to conform by SCAG on July 6, 2017, and by the Federal Transit Administration (FTA)/FHWA on August 1, 2017. On September 6, 2018, SCAG’s Regional Council adopted the 2016 RTP/SCS Amendment No. 3 but conformity determination approval from the FHWA is pending. The proposed Project is listed in the 2017 Federal Transportation Improvement Program (FTIP) 17-00 under ID No. SDBSL08. The 2017 FTIP Consistency Amendment 17–18 was approved by SCAG on February 23, 2018, and by FTA/FHWA on March 26, 2018. The design concept and scope of the proposed Project is consistent with the project description in the 2016 RTP and 2017 FTIP and the “open to traffic” assumptions of the SCAG’s regional emissions analysis.

Under the HBP, the project description for the Barton Road Bridge Removal and Road Construction Project is as follows:
 BRIDGE NO. 54C0379, BARTON RD, OVER UP RR, 0.25 MI W ROUTE 215. REPLACE 2-LANE BRIDGE WITH NEW 2-LANE ASPHALT ROADWAY, MINOR SEISMIC CONTRIBUTION. THE CITY OF COLTON WILL BE THE IMPLEMENTING AGENCY FOR DESIGN AND CONSTRUCTION.

1.3 Purpose and Need
The proposed Project will dismantle and remove the Barton Road Bridge (State Bridge No. 54C0379), which has been determined to be structurally unsuitable. The road replacement comes as a viable alternative to replacing the bridge over the now-abandoned UPRR tracks. The goal is to provide a new at-grade level road with Class II bicycle paths and pedestrian sidewalks. The newly constructed roadway will be suitable for heavy duty trucks, passenger vehicles, commercial delivery vehicles, Class II bicycle lanes, and pedestrian sidewalks. The removal of the Barton Road Bridge will allow for needed Class II bicycle lanes meeting the requirements of the Cities of Grand Terrace and Colton.

1.3.1 Purpose
The purpose of the project is to provide safe connectivity between La Cadena Drive and the Barton Road/Interstate 215 (I-215) interchange and to facilitate efficient access between the Cities of Colton and Grand Terrace.

7.c
Packet Pg. 534 Attachment: Exhibit C_Part1 - Barton Road Bridge Removal ISMND (3479 : CEQA - Barton Road Bridge Removal and Road Construction

1. Proposed Project Description
8 1.3.2 Need
Barton Road Bridge was originally built in 1936 as a two-lane bridge over the Union Pacific Railroad (UPRR) railroad tracks (one lane in each direction). The bridge is structurally unsound and the 25-foot wide bridge deck does not provide adequate pedestrian or bicycle access. The sidewalk that exists on the bridge has been shut down for safety reasons. A review of the existing bridge’s As Built plans shows the design philosophy of the bridge does not account for seismic loading, which is critical for public safety in California. The Bridge Inspection Report shows a low sufficiency rating of 58.8 due to low load rating and a roadway geometry that does not meet the current standards of the American Association of State Highway and Transportation Officials (AASHTO). The railroad tracks below the bridge have been abandoned and removed. There is no longer the need to span the railroad tracks with a bridge.

1.4 Baseline and Forecast Conditions for No Build and
Build Alternatives
The proposed alternatives include the No Build and Build Alternative for opening year 2023 and horizon year 2045. The Project alternatives are described below. Previously referenced Figure 1-2 shows the features of the Build Alternative.

1.4.1 Existing Roadways and Traffic Conditions
The Barton Road Bridge Removal and Road Construction Project is located in the City of Colton at the southern city limit with the neighboring City of Grand Terrace. The City of Colton is proposing to remove an existing 175-foot long by 25-foot wide bridge. The two-lane bridge on Barton Road is approximately 0.25 mile east of La Cadena Drive and 0.25 mile west of the Interstate 215 (I-215) interchange (KOA 2020). The pedestrian pathway on the Barton Road Bridge has been closed to foot and bicycle traffic as it has been deemed unsafe for pedestrian use. The Barton Road Bridge has a posted speed limit of 35 miles per hour on the west side of the bridge. The Baseline (year) used for the analysis is 2019 because those are the most recent traffic data available. Table 1-1 lists the existing (2019) traffic data for the Barton Road between S. La Cadena Drive and Grand Terrace Road.

1.4.2 No Build Alternative
The No Build Alternative assumes that no bridge removal or improvements are made to Barton Road.

The No Build Alternative would maintain the existing conditions and provides a baseline for comparison of the impacts under the Build Alternative. Under the No Build Alternative, roadway performance would continue to deteriorate with the forecast increase in traffic.

Under NEPA, the No Build (No Action) Alternative consists of those transportation projects that are already planned for construction by or before opening year 2023. Consequently, the No Build alternative represents future travel conditions in the Barton Road study area without the Project and is the baseline against which the Build Alternative will be assessed to meet NEPA requirements.

Table 1-2 lists the No Build traffic data for the Opening Year 2023 and Horizon Year 2045 for Barton Road between S. La Cadena Drive and Grand Terrace Road.

1.4.3 Project Build Alternative
The Cities of Colton and Grand Terrace, in cooperation with Caltrans, propose to replace the existing two-lane Barton Road Bridge (which is approximately 175 feet long by 25 feet wide) on Barton Road over an abandoned UPRR single-track railway in Colton and Grand Terrace with a two-lane, at-grade asphalt roadway. Barton Road runs through both Colton and Grand Terrace. Improvements to Barton Road will begin at the east side of the Terrace Avenue intersection in Colton and extend to approximately 100 feet west of the intersection of Grand Terrace Avenue in Grand Terrace. The curbto-curb roadway width of 44 feet widens to approximately 70 feet west of Grand Terrace Avenue to tie into the improvements being made to the Barton Road/I-215 interchange. The total length of the roadway improvements is approximately 1,100 feet. The roadway will accommodate a 6-foot wide sidewalk on the north and south sides of Barton Road, an 8-foot wide striped Class II bicycle lane on each side of the roadway, and two 14-foot wide travel lanes. Lane configurations transition to join existing improvements west of Grand Terrace Avenue.

Improvements include the following:
 Demolition and removal of the existing bridge, abutments, and retaining walls on Barton Road.  Removal and reconstruction of the drainage outlet west of Grand Terrace Avenue.  Construction of a drainage culvert across Barton Road in the vicinity of the abandoned tracks.  Relocation of the Riverside Highland Water Company line, the City of Colton waterline, fiber optic cables, and a gas line in the existing bridge and roadway and relocation of overhead telephone lines along the north side of Barton Road.

7.c
Packet Pg. 537 Attachment: Exhibit C_Part1 - Barton Road Bridge Removal ISMND (3479 : CEQA - Barton Road Bridge Removal and Road Construction

1. Proposed Project Description
11  Removal of approximately 5,500 cubic yards (cy) of soil, and fill of approximately 4,300 cy to bring the bridge area to grade.
 Construction of an asphalt roadway and removal of the vertical crest curve, thereby improving stopping sight distance consistent with the Cities’ standards for Barton Road’s roadway classification.
 Construction of curb ramps to Americans with Disabilities Act (ADA) standards at the intersection of Barton Road and Terrace Avenue.
 Construction of 6-foot wide sidewalks and 8-foot wide Class II bike lanes on the north and south sides of Barton Road within the project limits.
 Construction of driveway approaches joining existing driveways in compliance with Grand Terrace and Colton City standards.
 Removal of a retaining wall along the north side of the Barton Road right-of-way in front of Lineage Logistics.
 Identification and provision of a construction staging area in the vicinity of the improvements.  Closure of Barton Road between Terrace Avenue and Grand Terrace Avenue during construction and provision of a detour for traffic.

The Project will require approximately 0.20 acre of temporary construction easements and slope easements. The majority of improvements, with the exception of driveway grading to match the lowered street elevation, will be contained to within the Cities’ existing right-of-way. Approximately 3,800 square feet will be acquired to increase the right-of-way at the location of the existing bridge to 50 feet in each direction. A sliver of permanent right-of-way (approximately 50 square feet) will be acquired in front of Assessor’s Parcel Number (APN) 027-522-316. Previously referenced Figure 1-1 provides the regional and project location map. Previously referenced Figure 1-2 shows the project features.

The Traffic Study Report prepared by KOA Corporation (2020) provided the existing traffic volume data, which serve as a baseline by which the future traffic volume projections are determined. Table 1-3 summarizes the average annual daily traffic (ADT) volumes, truck percentage, levels of service, and average speeds along Barton Road at existing year (2019).

1.4.4 Comparison of Existing/Baseline and Build Alternatives CEQA requires that the proposed Project emissions be compared to existing/baseline conditions. The Project would not affect regional traffic demand or distribution, and traffic volumes along the Project roadways are expected to remain the same between Build and No Build Alternatives for both the Opening Year (2023) and the Horizon Year (2045).

The Traffic Study Report prepared for the proposed Project concluded that the proposed Project would improve traffic flow along Barton Road at opening year (2023) and Horizon Year (2045). While volumes are expected to increase from the existing year to future years, this is attributed to regional population growth and other factors external to the operation of the proposed Project.

NEPA requires that the proposed Project emissions be compared to no-build conditions for the Opening and Horizon Years. The proposed Project would improve operations on Barton Road, it would not affect regional traffic demand or distribution, and traffic volumes along the Project roadways are expected to remain the same between Build and No Build Alternatives for both the Opening Year (2023) and the Horizon Year (2045). The Traffic Study Report concluded that the proposed Project would improve traffic flow along Barton Road at Opening Year (2023) and Horizon Year (2045).

Table 1-4 summarizes design features and operational impacts on traffic conditions near the Project Area.

1.5 Construction Activities and Schedule
During implementation of the Barton Road Bridge Removal and Road Construction, traffic will be detoured around the proposed Project area. The Barton Road Bridge will be closed to through traffic for the duration of the 14-month proposed Project. From the east, traffic will be diverted through S.

La Crosse Avenue, west on De Berry Street, and north on S. Terrace Road before reconnection to Barton Road west of the proposed Project area. From the west, cars will be directed south on S.

Terrace Avenue, east on De Berry Street, and north on La Crosse Avenue before reconnection with Barton Road.

During construction, pedestrians and bicycles would be detoured around the proposed Project site from both directions through the same routes as vehicles diverted. The public transportation bus system is run by OmniTrans, the primary transit agency in the San Bernardino Valley (OmniTrans 2020). The bus line does not use the existing route over Barton Road in the proposed Project area.

Therefore, there will not be disruptions to public transit for the duration of the Project.

7.c
Packet Pg. 540 Attachment: Exhibit C_Part1 - Barton Road Bridge Removal ISMND (3479 : CEQA - Barton Road Bridge Removal and Road Construction

1. Proposed Project Description
14 Construction of the proposed Project would require the closure of Barton Road, which would result in removing several driveways to operational businesses. These businesses will have access to Barton Road, east of the bridge removal, without impacts from continued operation.

The construction equipment and staging for the contractor will be in located north of Barton Road, east of the former track alignment. The location will serve as base of operations for daily activity on the Project site. The removal of the bridge will generate a large number of truck trips for haul away of material and asphalt. The site map provided in Figure 1-2, shows the proposed Project construction boundaries and staging areas.

Construction equipment would enter the Project site from the west side of the proposed Project area on Barton Road, arriving from the designated detour around the Project site from I-215 or from S. La Cadena Drive. The other possible approach is the east side of the proposed Project site on Barton Road, onto the east side of the Barton Road Bridge for the process of removal or grading.

Construction is planned to last approximately 14 months. The proposed Project would be operational in 2023 and the full buildout year is 2045. Emissions from construction-related activities are thus considered temporary as defined in 40 Code of Federal Regulations (CFR) 93.123(c)(5); and are not required to be included in particulate matter (PM) hot-spot analyses to meet conformity requirements.

2. Regulatory Setting
15 2. Regulatory Setting
Many statutes, regulations, plans, and policies have been adopted at the federal, State, and local levels to address air quality issues related to transportation and other sources. The proposed Project is subject to air quality regulations at each of these levels. This section introduces the pollutants governed by these regulations and describes the regulation and policies that are relevant to the proposed Project.

2.1 Pollutant-Specific Overview
Air pollutants are governed by multiple federal and State standards to regulate and mitigate health impacts. At the federal level, there are six criteria pollutants for which National Ambient Air Quality Standards (NAAQS) have been established: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter (particulate matter less than 10 microns in diameter [PM10] and particulate matter less than 2.5 microns in diameter [PM2.5]), and in some areas (although not in California), sulfur dioxide (SO2). The United States Environmental Protection Agency (U.S. EPA) has also identified nine priority mobile source air toxics (MSAT): 1,3-butadiene, acetaldehyde, acrolein, benzene, diesel particulate matter (diesel PM), ethylbenzene, formaldehyde, naphthalene, and polycyclic organic matter. In California, sulfates, visibility-reducing particles, hydrogen sulfide, and vinyl chloride are also regulated.

2.1.1 Criteria Pollutants
The Federal Clean Air Act (FCAA) requires the U.S. EPA to set NAAQS for six criteria air contaminants:
ozone, particulate matter, carbon monoxide, nitrogen dioxide, lead, and sulfur dioxide. It also permits states to adopt additional or more protective air quality standards if needed. California has set standards for certain pollutants. Table 2-1 documents the current air quality standards, while Table 2-2 summarizes the sources and health effects of the six criteria pollutants and pollutants regulated in California.

2.1.2 Mobile Source Air Toxics
Controlling air toxic emissions became a national priority with the passage of the Clean Air Act Amendments (CAAA) of 1990, whereby Congress mandated that the U.S. EPA regulate 188 air toxics, also known as hazardous air pollutants. The U.S. EPA has assessed this expansive list in its rule on the Control of Hazardous Air Pollutants from Mobile Sources (Federal Register, Vol. 72, No. 37, page 8430, February 26, 2007), and identified a group of 93 compounds emitted from mobile sources that are part of U.S. EPA’s Integrated Risk Information System (https://www.epa.gov/iris). In addition, the U.S. EPA identified nine compounds with significant contributions from mobile sources that are among the national and regional-scale cancer risk drivers or contributors and non-hazard contributors from the 2011 National Air Toxics Assessment (https://www.epa.gov/national-air-toxicsassessment). These are 1,3-butadiene, acetaldehyde, acrolein, benzene, diesel particulate matter

2. Regulatory Setting
17 A California standards for ozone, carbon monoxide (except 8-hour Lake Tahoe), sulfur dioxide (1 and 24 hour), nitrogen dioxide, and particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations.

B
Federal standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year. The ozone standard is attained when the fourth highest 8-hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard. For PM10, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 μg/m3 is equal to or less than one.

For PM2.5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard. Contact the U.S. EPA for further clarification and current national policies.

C On October 1, 2015, the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm.

Transportation conformity applies in newly designated nonattainment areas for the 2015 national 8-hour ozone primary and secondary standards on and after August 4, 2019 (see Transportation Conformity Guidance for 2015 Ozone NAAQS Nonattainment Areas).

D ppm = parts per million
E
Transportation conformity requirements for CO no longer apply after June 1, 2018 for the following California Carbon Monoxide Maintenance Areas (see U.S. EPA CO Maintenance Letter).

F
On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 μg/m3 to 12 μg/m3. The existing national 24-hour PM2.5 standards (primary and secondary) were retained at 35 μg/m3 , as was the annual secondary standard of
15 μg/m3
. The existing 24-hour PM10 standards (primary and secondary) of 150 μg/m3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years.

G μg/m3
= micrograms per cubic meter
H The 65 μg/m3
PM2.5 (24-hr) NAAQS was not revoked when the 35 μg/m3 NAAQS was promulgated in 2006. The 15 μg/m3 annual PM2.5 standard was not revoked when the 12 μg/m3 standard was promulgated in 2012. Therefore, for areas designated nonattainment or nonattainment/maintenance for the 1997 and or 2006 PM2.5 NAAQS, conformity requirements still apply until the NAAQS are fully revoked.

I
Final 1-hour NO2 NAAQS published in the Federal Register on February 9, 2010, effective March 9, 2010. Initial area designation for California (2012) was attainment/unclassifiable throughout. Project-level hot spot analysis requirements do not currently exist. Near-road monitoring starting in 2013 may cause re-designation to nonattainment in some areas after 2016.

J
On June 2, 2010, a new 1-hour SO2 standard was established and the existing 24-hour and annual primary standards were revoked. To attain the 1-hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated nonattainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved.

K
Secondary standard, the levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant rather than health. Conformity and environmental analysis address both primary and secondary NAAQS.

L
Lead NAAQS are not considered in Transportation Conformity analysis.

M In 1989, the ARB converted both the general statewide 10-mile visibility standard and the Lake Tahoe 30-mile visibility standard to instrumental equivalents, which are "extinction of 0.23 per kilometer" and "extinction of 0.07 per kilometer" for the statewide and Lake Tahoe Air Basin standards, respectively.

N The ARB has identified vinyl chloride and the particulate matter fraction of diesel exhaust as toxic air contaminants. Diesel exhaust particulate matter is part of PM10 and, in larger proportion, PM2.5. Both the ARB and U.S. EPA have identified lead and various organic compounds that are precursors to ozone and PM2.5 as toxic air contaminants.

Pollutant Principal Health and Atmospheric Effects Typical Sources Ozone (O3) High concentrations irritate lungs. Long-term exposure may cause lung tissue damage and cancer. Long-term
exposure damages plant materials and reduces crop
productivity. Precursor organic compounds include
many known toxic air contaminants. Biogenic VOC may
also contribute.

Low-altitude ozone is almost entirely formed from
reactive organic gases/volatile organic compounds
(ROG or VOC) and nitrogen oxides (NOx) in the
presence of sunlight and heat. Common precursor
emitters include motor vehicles and other internal
combustion engines, solvent evaporation, boilers,
furnaces, and industrial processes.

Carbon
Monoxide
(CO)
CO interferes with the transfer of oxygen to the blood
and deprives sensitive tissues of oxygen. CO also is a
minor precursor for photochemical ozone. Colorless,
odorless.

Combustion sources, especially gasoline-powered
engines and motor vehicles. CO is the traditional
signature pollutant for on-road mobile sources at
the local and neighborhood scale.

Respirable
Particulate

The 2007 U.S. EPA rule mentioned above requires controls that will dramatically decrease MSAT emissions through cleaner fuels and cleaner engines. According to an FHWA analysis using U.S. EPA's MOVES 2014a model, even if vehicle activity (vehicle-miles traveled, VMT) increases by 45 percent from 2010 to 2050 as forecast, a combined reduction of 91 percent in the total annual emission rate for the priority MSATs is projected for the same time period, as shown in Figure 2-1.

20 2.1.3 Greenhouse Gases
The term greenhouse gas (GHG) is used to describe atmospheric gases that absorb solar radiation and subsequently emit radiation in the thermal infrared region of the energy spectrum, trapping heat in the Earth’s atmosphere. These gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor, among others. A growing body of research attributes long-term changes in temperature, precipitation, and other elements of Earth’s climate to large increases in GHG emissions since the mid-19th century, particularly from human activity related to fossil fuel combustion.

Anthropogenic GHG emissions of particular interest include CO2, CH4, N2O, and fluorinated gases.

GHGs differ in how much heat each traps in the atmosphere (global warming potential, or GWP). CO2 is the most important GHG, so amounts of other gases are expressed relative to CO2, using a metric called “carbon dioxide equivalent” (CO2e). The global warming potential of CO2 is assigned a value of 1, and the warming potential of other gases is assessed as multiples of CO2. For example, the 2007 International Panel on Climate Change Fourth Assessment Report calculates the GWP of CH4 as 25 and the GWP of N2O as 298 over a 100-year time horizon.1 Generally, estimates of all GHGs are summed to obtain total emissions for a project or given time period, usually expressed in metric tons (MTCO2e), or million metric tons (MMTCO2e).2
As evidence has mounted for the relationship of climate changes to rising GHGs, federal and state governments have established numerous policies and goals targeted to improving energy efficiency and fuel economy, and reducing GHG emissions. Nationally, electricity generation is the largest source of GHG emissions, followed by transportation. In California, however, transportation is the largest contributor to GHGs.

At the federal level, NEPA (42 United States Code [USC] Part 4332) requires federal agencies to assess the environmental effects of their proposed actions prior to making a decision on the action or project.

To date, no national standards have been established for nationwide mobile-source GHG reduction targets, nor have any regulations or legislation been enacted specifically to address climate change and GHG emissions reduction at the project level. However, the U.S. EPA and the National Highway Traffic Safety Administration issued the first corporate fuel economy standards in 2010, requiring cars and light-duty vehicles to achieve certain fuel economy targets by 2016, with the intention of gradually increasing the targets and the range of vehicles to which they would apply.

California has enacted aggressive GHG reduction targets, starting with Assembly Bill (AB) 32, the California Global Warming Solutions Act of 2006. AB 32 is California’s signature climate change legislation. It set the goal of reducing statewide GHG emissions to 1990 levels by 2020, and required the California Air Resources Board (CARB) to develop a Scoping Plan that describes the approach

21 California will take to achieve that goal and to update it every 5 years. In 2015, Governor Jerry Brown enhanced the overall adaptation planning effort with Executive Order (EO) B-30-15, establishing an interim GHG reduction goal of 40 percent below 1990 levels by 2030, and requiring State agencies to factor climate change into all planning and investment decisions.

Senate Bill (SB) 375, the Sustainable Communities and Climate Protection Act of 2008, furthered State climate action goals by mandating coordinated transportation and land use planning through the preparation of Sustainable Communities Strategies (SCSs). The CARB sets GHG emissions reduction targets for passenger vehicles for each region. Each regional metropolitan planning organization must include in its regional transportation plan an SCS proposing action toward achieving the regional emission reduction targets.3
With these and other State Senate and Assembly bills and executive orders, California advances an innovative and proactive approach to dealing with GHG emissions and climate change.

2.1.4 Asbestos
Asbestos is a term used for several types of naturally occurring fibrous minerals that are a human health hazard when airborne. The most common type of asbestos is chrysotile, but other types such as tremolite and actinolite are also found in California. Asbestos is classified as a known human carcinogen by state, federal, and international agencies and was identified as a toxic air contaminant by CARB in 1986. All types of asbestos are hazardous and may cause lung disease and cancer.

Asbestos can be released from serpentine and ultramafic rocks when the rock is broken or crushed.

At the point of release, the asbestos fibers may become airborne, causing air quality and human health hazards. These rocks have been commonly used for unpaved gravel roads, landscaping, fill projects, and other improvement projects in some localities. Asbestos may be released to the atmosphere due to vehicular traffic on unpaved roads, during grading for development projects, and at quarry operations. All of these activities may have the effect of releasing potentially harmful asbestos into the air. Natural weathering and erosion processes can act on asbestos-bearing rock and make it easier for asbestos fibers to become airborne if such rock is disturbed.

Serpentine may contain chrysotile asbestos, especially near fault zones. Ultramafic rock, a rock closely related to serpentinite, may also contain asbestos minerals. Asbestos can also be associated with other rock types in California, though much less frequently than serpentinite and/or ultramafic rock. Serpentinite and/or ultramafic rock are known to be present in 44 of California’s 58 counties.

These rocks are particularly abundant in counties of the Sierra Nevada foothills, the Klamath Mountains, and Coast Ranges. The California Department of Conservation, Division of Mines and Geology has developed a map showing the general location of ultramafic rock in the state (www.conservation.ca.gov/cgs/minerals/hazardous_minerals/asbestos/Pages/index.aspx).

2. Regulatory Setting
22 2.2 Regulations

2.2.1 Federal and California Clean Air Acts
The FCAA, as amended, is the primary federal law that governs air quality while the California Clean Air Act (CCAA) is its companion State law. These laws and related regulations by the U.S. EPA and CARB set standards for the concentration of pollutants in the air. At the federal level, these standards are called NAAQS. NAAQS and State ambient air quality standards have been established for six transportation-related criteria pollutants that have been linked to potential health concerns: CO; NO2; O3; PM, which is broken down for regulatory purposes into PM10 and PM2.5; and SO2. In addition, national and state standards exist for lead (Pb), and state standards exist for visibility reducing particles, sulfates, hydrogen sulfide (H2S), and vinyl chloride. The NAAQS and State standards are set at levels that protect public health with a margin of safety, and are subject to periodic review and revision. Both State and federal regulatory schemes also cover Toxic Air Contaminants (TACs); some criteria pollutants are also TACs, or may include certain TACs in their general definitions.

2.2.2 Transportation Conformity
The conformity requirement is based on FCAA Section 176(c), which prohibits the U.S. Department of Transportation (USDOT) and other federal agencies from funding, authorizing, or approving plans, programs, or projects that do not conform to the State Implementation Plan (SIP) for attaining the NAAQS. “Transportation Conformity” applies to highway and transit projects and takes place on two levels: the regional—or, planning and programming level—and the project level. The proposed project must conform at both levels to be approved.

Conformity requirements apply only in nonattainment and “maintenance” (former nonattainment) areas for the NAAQS, and only for the specific NAAQS that are or were violated. The U.S. EPA regulations at 40 CFR 93 govern the conformity process. Conformity requirements do not apply in unclassifiable/attainment areas for NAAQS and do not apply at all for state standards regardless of the status of the area.

Regional conformity is concerned with how well the regional transportation system supports plans for attaining the NAAQS for CO, NO2, O3, PM10, PM2.5, and in some areas (although not in California), SO2. California has attainment or maintenance areas for all of these transportation-related “criteria pollutants” except SO2, and also has a nonattainment area for Pb; however, Pb is not currently required by the FCAA to be covered in transportation conformity analysis. Regional conformity is based on emission analysis of RTPs and FTIPs that include all transportation projects planned for a region over a period of at least 20 years (for the RTP), and 4 years (for the FTIP). RTP and FTIP conformity uses travel demand and emission models to determine whether or not the implementation of those projects would conform to emission budgets or other tests at various analysis years showing that requirements of the FCAA and the SIP are met. If the conformity analysis is successful, the Metropolitan Planning Organization, the FHWA, and the FTA make the determinations that the RTP and FTIP are in conformity with the SIP for achieving the goals of the

7.c

2. Regulatory Setting
23 FCAA. Otherwise, the projects in the RTP and/or FTIP must be modified until conformity is attained. If the design concept, scope, and “open-to-traffic” schedule of a proposed transportation project are the same as described in the RTP and the FTIP, then the proposed project meets regional conformity requirements for purposes of project-level analysis.

Project-level conformity is achieved by demonstrating that the project comes from a conforming RTP and FTIP and the project has a design concept and scope4 that has not changed significantly from those in the RTP and FTIP. If the design concept and scope have changed substantially from that used in the RTP Conformity analysis, RTP and FTIP amendments may be needed. Project-level conformity also needs to demonstrate that project analyses have used the latest planning assumptions and U.S. EPA-approved emissions models; the project complies with any control measures in the SIP in PM areas. Furthermore, additional analyses (known as hot-spot analyses) may be required for projects located in CO and PM nonattainment or maintenance areas to examine localized air quality impacts.

2.2.3 National Environmental Policy Act
NEPA requires that policies and regulations administered by the federal government be consistent with its environmental protection goals. NEPA also requires that federal agencies use an interdisciplinary approach to planning and decision-making for any actions that could affect the environment. It requires environmental review of federal actions including the creation of environmental documents that describe the environmental effects of a proposed project and its alternatives (including a section on air quality impacts).

2.2.4 California Environmental Quality Act
CEQA5 is a statute that requires State and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts, if feasible. CEQA documents address CCAA requirements for transportation projects. Although State standards are often stricter than federal standards, the State has no conformity process.

2.2.5 Local
The U.S. EPA has delegated responsibility to air districts to establish local rules to protect air quality.

Caltrans’ Standard Specification 14-9.02 (Caltrans 2015) requires compliance with all applicable air quality laws and regulations including local and air district ordinances and rules.

SCAQMD and the SCAG are responsible for formulating and implementing the Air Quality Management Plan (AQMP) for the South Coast Air Basin. The main purpose of an AQMP is to bring

4 "Design concept" means the type of facility that is proposed, such as a freeway or arterial highway. "Design scope" refers to those aspects of the project that would clearly affect capacity and thus any regional emissions analysis, such as the number of lanes and the length of the project. 5

24 the area into compliance with federal and State air quality standards. Every three years, SCAQMD prepares a new AQMP, updating the previous plan and 20-year horizon (SCAQMD 2016).

SCAQMD approved the 2016 AQMP on March 3, 2017, and submitted the plan to CARB on March 10, 2017. Key elements of the 2016 AQMP include the following:
 Calculating and taking credit for co-benefits from other planning efforts (e.g., climate, energy, and transportation).
 A strategy with fair-share emission reductions at the federal, State, and local levels.  Investment in strategies and technologies meeting multiple air quality objectives.  Seeking new partnerships and significant funding for incentives to accelerate deployment of zero-emission and near-zero emission technologies.
 Enhanced socioeconomic assessment, including an expanded environmental justice analysis.  Attainment of the 24-hour PM2.5 standard in 2019 with no additional measures.  Attainment of the annual PM2.5 standard by 2025 with implementation of a portion of the O3 strategy.
 Attainment of the 1-hour O3 standard by 2022 with no reliance on “black box” future technology (FCAA Section 182(e)(5) measures).

SCAG is responsible under the FCAA for determining the conformity of projects, plans, and programs with the SCAQMD AQMP. As indicated in the SCAQMD CEQA Air Quality Handbook (1993), there are two main indicators of consistency:
 Whether the project would result in an increase in the frequency or severity of existing air quality violations or cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the AQMP; and  Whether the project would exceed the AQMP’s assumptions for 2020 or increments based on the year of project buildout and phase.

3. Affected Environment
25 3. Affected Environment
The topography of a region can substantially affect airflow and resulting pollutant concentrations.

California is divided into 15 air basins with similar topography and meteorology to better manage air quality throughout the State. Each air basin has a local air district that is responsible for identifying and implementing air quality strategies to comply with ambient air quality standards.

The Barton Road Bridge Removal and Road Construction Project is on the boundary of the City of Colton and the City of Grand Terrace, in San Bernardino County, an area within the South Coast Air Basin, which also includes non-desert portions of Los Angeles County and the western portions of San Bernardino and Riverside Counties. The SCAQMD administers air quality regulation in the South Coast Air Basin. Current population for San Bernardino County is 2.18 million (U.S. Census 2019). San Bernardino County’s economy is largely driven by retail trade, healthcare, manufacturing, transport/warehouse, and accommodation/food (San Bernardino County Economic Development Agency 2020).

3.1 Climate, Meteorology, and Topography
Meteorology (weather) and terrain can influence air quality. Certain weather parameters are highly correlated to air quality, including temperature, the amount of sunlight, and the type of winds at the surface and above the surface. Winds can transport ozone and ozone precursors from one region to another, contributing to air quality problems downwind of source regions. Furthermore, mountains can act as a barrier that prevents ozone from dispersing.

The San Bernardino climatological station, maintained by SCAQMD, is located near the Project site and is representative of meteorological conditions near the proposed Project. Figure 3-1 shows a wind rose illustrating the predominant wind patterns near the proposed Project. The climate of the Project Area is generally Mediterranean in character, with cool winters (lows average 42.1° Fahrenheit [°F] in January) and warm, dry summers (average 97.3 °F in August).6 Temperature inversions are common, affecting localized pollutant concentrations in the winter and enhancing ozone formation in the summer. The San Gabriel Mountains, ranging to 10,000 feet in altitude (U.S. Forest Service 2015), tend to trap pollutants in the region by limiting airflow. Annual average rainfall is 16.01 inches (at San Bernardino County Yard SBYC1), mainly falling during the winter months.

3.2.1 Criteria Pollutants and Attainment Status
Air quality monitoring stations are located throughout the nation and are maintained by local air districts and State air quality regulating agencies. The U.S. EPA uses data collected at permanent monitoring stations to identify regions as “attainment,” “nonattainment,” or “maintenance,” depending on whether the regions meet the requirements stated in the primary NAAQS.

29 Nonattainment areas are imposed with additional restrictions as required by the U.S. EPA. In addition, different classifications of nonattainment (e.g., marginal, moderate, serious, severe, and extreme) are used to classify each air basin in the State on a pollutant-by-pollutant basis. The classifications are used as a foundation to create air quality management strategies to improve air quality and comply with the NAAQS.

The SCAQMD San Bernardino Air Quality Monitoring Station located at San Bernardino at 24302 4th Street, monitors five criteria pollutants (O3, CO, NO2, PM10 and PM2.5). Table 3-2 lists air quality trends identified for data collected at both air quality monitoring stations between 2015 and 2019.

3.2.2 Mobile Source Air Toxics
In addition to the criteria air pollutants for which there are NAAQS, the EPA also regulates air toxics.

Most air toxics originate from human-made sources, including on-road mobile sources, non-road mobile sources (e.g., airplanes), area sources (e.g., dry cleaners), and stationary sources (e.g., factories).

Controlling air toxic emissions became a national priority with the passage of the FCAA Amendments of 1990, whereby Congress mandated that the U.S. EPA regulate 188 air toxics, also known as hazardous air pollutants. The U.S. EPA has assessed this expansive list in its latest rule on the Control of Hazardous Air Pollutants from Mobile Sources (Federal Register, Volume 73, No. 201, page 61,358; October 16, 2008) and identified a group of 93 compounds emitted from mobile sources that are listed in its Integrated Risk Information System. In addition, the U.S. EPA identified nine compounds with significant contributions from mobile sources that are among the national and regional-scale cancer risk drivers from its 2011 National Air Toxics Assessment. These are acrolein, benzene, 1,3- butadiene, acetaldehyde, diesel PM, ethylbenzene, formaldehyde, naphthalene, and polycyclic organic matter. While the FHWA considers these the priority MSAT, the list is subject to change and may be adjusted in consideration of future U.S. EPA rules. Table 3-3 lists the ambient concentrations

31 of the MSATs at the San Bernardino 4th Street Monitoring Station (the closest MSAT monitoring station) in the Project vicinity.

3.2.3 Greenhouse Gas and Climate Change
CO2, as part of the carbon cycle, is an important compound for plant and animal life, but also accounted for 84 percent of California’s total GHG emissions in 2017. Transportation, primarily onroad travel, is the single largest source of CO2 emissions in the State.

The proposed Project is located in San Bernardino County, and is included in the SCAG RTP/SCS and FTIP. The proposed Project appears on the Grouped Projects listing under the Adopted Final 2019 FTIP under the Federal Highway Bridge Program (HBP) ID# 1056. The Final 2019 FTIP HBP was adopted on September 6, 2018, by the SCAG Regional Council, and later updated to the 2019 Grouped Projects Detailed Backup Lists on November 1, 2019. The proposed Project is described in the 2019 FTIP HBP as the removal of Barton Road Bridge (Bridge No. 54C0379) over the previous Union Pacific rail road tracks 0.25 mile west of the I-215. The proposed Project would replace the two-lane bridge with a four-lane asphalt road at grade-level, with associated bicycle lanes. Minor seismic activity contribution would occur during bridge removal. The City of Colton will be the implementing lead agency for design and construction.

3.3 Sensitive Receptors
Existing land uses in the proposed Project area include single-family and multifamily residences, a mobile home park, industrial storage yards, food distribution facilities, commercial uses, vacant land, and a clinical laboratory.

Land uses north of Barton Road and west of the S. La Cadena Drive include single-family residences, a mobile home park, commercial park, and industrial food distribution center.

Land uses south of Barton Road adjacent to the proposed Project area consist of a construction equipment yard, commercial supply companies, a collision center, and office uses.

Land uses east of the proposed Project area include a clinical laboratory, and a mobile home park.

Figure 3-3 presents the locations of the sensitive receptors near the Project area.

3.4 Conformity Status
The Transportation Conformity Rule is based on FCAA Section 176(c), which prohibits the USDOT and other federal agencies from funding, authorizing, or approving plans, programs, or projects that do not conform to the SIP for attaining the NAAQS. Conformity applies to highway and transit projects

35 and takes place on two levels: the regional (or planning and programming) level and the project level. The proposed Project must conform at both levels to be approved.

Conformity requirements apply only in nonattainment and maintenance (former nonattainment) areas for the NAAQS, and only for the specific NAAQS that are or were violated. U.S. EPA regulations at 40 CFR 93 govern the conformity process. Conformity requirements do not apply in unclassifiable/attainment areas for the NAAQS and do not apply at all for State standards regardless of the status of the area.

3.4.1 Regional Conformity
Regional conformity is concerned with how well the regional transportation system supports plans for attaining the NAAQS for CO, NO2, O3, PM10, and PM2.5, and in some areas (although not in California), SO2. California has nonattainment or maintenance areas for all of these transportationrelated “criteria pollutants” except SO2, and also has a nonattainment area for Pb; however, the FCAA does not currently require Pb to be covered in transportation conformity analysis.

As part of the Clean Air Rules of 2004, the U.S. EPA published a final rule in the Federal Register on July 1, 2004, to amend the Transportation Conformity Rule to include criteria and procedures for the new 8-hour O3 and PM2.5 NAAQS. The final rule addressed a March 2, 1999, court decision by incorporating U.S. EPA and USDOT guidance. On July 20, 2004, the EPA published a technical correction notice to correct two minor errors in the July 1, 2004, notice. To remain consistent with the stricter federal standards, CARB approved a new 8-hour O3 standard (0.07 parts per million [ppm], not to be exceeded) on April 28, 2005. Additionally, the CARB retained the current 1-hour-average standard for O3 (0.09 ppm) and the current monitoring method for O3, which uses the ultraviolet photometry method.

Table 2 of 40 CFR, Section 93.126 lists the types of projects that are exempt. The bridge removal and new at-grade level street widening with no additional lanes as part of the Build Alternative is one of the exempt projects listed in Table 2. Therefore, the proposed Project is exempt from all emissions analyses. Projects that are included in Table 3 of 40 CFR, Section 93.127 are exempt from regional conformity. Because the proposed Project would remove the Barton Street Bridge and widen a new at-grade level asphalt road with no additional lanes, it is exempt from regional emissions analysis.

The proposed Project is located in San Bernardino County, located in the 2019 FTIP under the HBP, is consistent with the SCAG’s approved RTP/SCS. The Final 2019 FTIP includes all federally funded transportation projects, the regional plan RTP/SCS was adopted by SCAG on September 6, 2018. The proposed Project appears on the Grouped Projects listing under the Adopted Final 2019 FTIP under the HBP ID No. 1056. The Final 2019 FTIP HBP 1056 was also adopted on September 6, 2018, by the SCAG Regional Council, and updated to the 2019 Grouped Projects Detailed Backup Lists on November 1, 2019 (Appendix A).

3.4.2 Project-Level Conformity
The proposed Project is in an attainment/maintenance area for federal CO standards, a nonattainment area for federal PM2.5, and an attainment/maintenance area for federal PM10 standards; thus, 40 CFR 93.109 requires a project-level hot-spot analysis for all three pollutants. The proposed Project does not cause or contribute to any new localized CO, PM2.5, and/or PM10 violations, or delay timely attainment of any NAAQS or any required interim emission reductions or other milestones during the timeframe of the transportation plan (or regional emissions analysis).

3.4.3 Interagency Consultation
Pursuant to the transportation conformity rules and regulations, all nonexempt projects must go through review by the SCAG Transportation Conformity Working Group (TCWG). Based on the exempt projects listed in Table 2 of 40 CFR 93.126 - Widening narrow pavements or reconstructing bridges (no additional travel lanes), the proposed Project is exempt from all project-level conformity requirements. A copy of the Transportation Air Quality Conformity Findings Checklist is included in Appendix B.

3.5 NEPA Analysis/Requirement
NEPA applies to all projects that receive federal funding or involve a federal action. NEPA requires that all reasonable alternatives for a proposed project be rigorously explored and objectively evaluated. As described above, the proposed Project is listed in a conforming RTP and FTIP.

Construction will last less than three years and will not substantially affect traffic due to detours, road

3. Affected Environment
37 closures, and/or temporary terminations. Thus, impacts of the resulting traffic flow changes do not need to be analyzed.

3.6 CEQA Analysis/Requirement
This air quality study addresses pollutants for which California has established air quality standards (O3, PM10, PM2.5, CO, NO2, SO2, Pb, visibility-reducing particles, sulfates, H2S, and vinyl chloride), as well as GHGs, MSAT, and asbestos. Similar to NEPA, the analysis/documentation requirements for CEQA vary by pollutant (see the table in Section 4.1), ranging from a narrative describing that the pollutant is typically not a transportation issue to an emission analysis. Because construction would not last more than three years or substantially affect traffic due to detours, lane closures, and/or temporary bridge closures, the impacts of the resulting traffic flow changes do not need to be analyzed. For CEQA analyses, emissions from the future year Build Alternative scenarios are compared to emissions from the existing/baseline conditions.

EMission FACtors (EMFAC) is California’s federally-approved on-road mobile source emission inventory model that reflects California-specific driving and environmental conditions, fleet mix, and mobile source regulations. EMFAC is a computer model used for estimating emission rates for onroad mobile sources in California for calendar years 2000 to 2050. The EMFAC model supports CARB's regulatory and air quality planning efforts and fulfills the Federal Clean Air Act and the Federal Highway Administration’s transportation planning requirements. The U.S. EPA has approved EMFAC2017 for use in State Implementation Plan (SIP) and transportation conformity analyses. On September 27, 2019, the U.S. EPA and the National Highway Traffic Safety Administration (NHTSA) published the “Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program.” (84 Fed. Reg. 51,310 (September 27, 2019.) The Part One Rule revokes California’s authority to set its own greenhouse gas emissions standards and set zero emission vehicle mandates in California.

Therefore, the approval of the Rule means that the previously approved EMFAC2017 model no longer accurately estimates future transportation emissions and requires off-model adjustment factors until the next update in order to reflect the impacts of the Rule. Note that the Rule affects emissions only from gasoline-powered Light Duty Vehicles (i.e. LDA, LDT1, LDT2, and MDV vehicle categories). CARB has provided off-model adjustment factors for EMFAC2017 to account for the impacts of the Rule (CARB 2019). These adjustment factors are multipliers that were applied to EMFAC emissions outputs for this project.

4. Environmental Consequences
39 4. Environmental Consequences
This section describes the methods, impact criteria, and results of air quality analyses of the proposed Project. Analyses in this report were conducted using methodology and assumptions that are consistent with the requirements of NEPA, CEQA, the CAAAs of 1990, and the CCAA of 1988. The analyses also use guidelines and procedures provided in applicable air quality analysis protocols, such as the Transportation Project-Level Carbon Monoxide Protocol (CO Protocol; Garza et al., 1997), Transportation Conformity Guidance for Quantitative Hot-Spot Analyses in PM10 and PM2.5 Nonattainment and Maintenance Areas (U.S. EPA 2015), and the FHWA Updated Interim Guidance on Air Toxics Analysis in NEPA Documents (FHWA 2016).

4.1 Impact Criteria
Project-related emissions would have an adverse environmental impact if they result in pollutant emission levels that either create or worsen a violation of an ambient air quality standard (identified in previously referenced Table 2-1) or contribute to an existing air quality violation. As analyzed in the following sections, neither the short-term construction impacts nor the long-term operational impacts would exceed thresholds with implementation of minimization measures.

4.2 Short-Term Effects (Construction Emissions)

4.2.1 Construction Equipment, Traffic Congestion, and Fugitive Dust
During construction, short-term degradation of air quality may occur due to the release of particulate emissions generated by excavation, grading, hauling, and other activities related to construction. Emissions from construction equipment also are anticipated and would include CO, NOx, volatile organic compounds (VOCs), directly emitted PM (PM2.5 and PM10), and TACs (e.g., diesel exhaust PM).

Site preparation and roadway construction would involve clearing, cut-and-fill activities, grading, and paving roadway surfaces. Construction-related effects on air quality from most roadway projects would be greatest during the site preparation phase because most engine emissions are associated with the excavation, handling, and transport of soils to and from the site. If not properly controlled, these activities would temporarily generate CO, NOx, VOCs, PM10, and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils.

Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after drying. PM10 emissions would vary from day to day, depending on the nature and magnitude of construction activity and local weather conditions. PM10

7.c
Packet Pg. 566 Attachment: Exhibit C_Part1 - Barton Road Bridge Removal ISMND (3479 : CEQA - Barton Road Bridge Removal and Road Construction

4. Environmental Consequences
40 emissions would also depend on soil moisture, the silt content of soil, wind speed, and the amount of equipment operating at the time. Larger dust particles would settle near the source, while finer particles would be dispersed over greater distances from the construction site.

In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, NOx, VOCs, and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase while those vehicles are delayed. These emissions would be temporary and limited to the immediate area surrounding the construction site. Areas within 500 feet of CARB-defined sensitive land uses would be labeled as no-idle areas where material storage/transfer and equipment maintenance activities are not to occur.

SO2 is generated by oxidation during combustion of organic sulfur compounds contained in diesel fuel. Off-road diesel fuel meeting federal standards can contain up to 5,000 ppm of sulfur, whereas on-road diesel is restricted to less than 15 ppm of sulfur. However, under California law and CARB regulations, off-road diesel fuel used in California must meet the same sulfur and other standards as on-road diesel fuel, so SO2-related issues due to diesel exhaust would be minimal.

The construction emissions were estimated for the proposed Project using the Sacramento Metropolitan Air Quality Management District’s Road Construction Emissions Model, Version 9.0.0, which is consistent with the guidance provided by the SCAQMD for evaluating construction impacts from roadway projects. Table 4-1 presents the maximum amount of construction-related emissions during a peak construction day (model data are provided in Appendix C). The PM10 and PM2.5 emissions assume a 50 percent control of fugitive dust as a result of watering and associated dustcontrol measures. The Project construction emissions presented below are based on the best information available at the time of calculations and specify that the schedule for construction of the Build Alternative is anticipated to take approximately 14 months. Additionally, the SCAQMD has established rules for reducing fugitive dust emissions. With the implementation of standard construction measures (providing 50 percent effectiveness) such as frequent watering (e.g., a minimum of twice per day) as well as Minimization Measures AQ-1 through AQ-6 (see Chapter 6, Minimization Measures), fugitive dust and exhaust emissions from construction activities would not result in any adverse air quality impacts.

4. Environmental Consequences
41 Construction activities would not last for more than three years at one general location, so construction-related emissions do not need to be included in regional and project-level conformity analysis (40 CFR, Section 93.123(c)(5)).

Prior to the commencement of any construction activities, the Construction Contractor will submit a Construction Emission Control Plan for review and approval to the City of Colton Department of Public Works, which will be implemented during construction. The Construction Emission Control Plan will comply with federal, State, and local regulations as specified below:
 The contractor will adhere to the Caltrans Standard Specifications for Construction, Sections

14.9-01, 14.9-02, 14-9.03, 18-1.02C, and 18-1.03 (or Greenbook equivalent specifications). Section 14-9-02 specifically requires compliance by the contractor with all applicable laws and regulations related to air quality, including air pollution control district and air quality management district regulations and local ordinances.
 Water or a dust palliative will be applied to the site and equipment as often as necessary to control fugitive dust emissions. Fugitive emissions generally must meet a “no visible dust” criterion either at the point of emissions or at the right-of-way line depending on local regulations in compliance with the SCAQMD Rule 403 (Fugitive Dust).  Soil binder will be spread on any unpaved roads used for construction purposes, and on all project construction parking areas (providing an estimated 50 percent reduction of fugitive emissions) in compliance with the SCAQMD Rule 403 (Fugitive Dust).  Trucks will be washed as they leave the right-of-way as necessary to control fugitive dust emissions in compliance with the SCAQMD Rule 403 (Fugitive Dust).  Construction equipment and vehicles will be properly tuned and maintained. All construction equipment will use low-sulfur fuel as required by California Code of Regulations (CCR) Title 17, Section 93114.
 A dust control plan will be developed documenting sprinkling, temporary paving, speed limits, and timely revegetation of disturbed slopes as needed to minimize construction impacts to existing communities in compliance with the SCAQMD Rule 403 (Fugitive Dust).  Equipment and material storage sites will be located as far away from residential and park uses as practicable. Construction areas will be kept clean and orderly in compliance with the SCAQMD Rule 402 (Nuisance).
 Environmentally sensitive areas will be established near sensitive air receptors. Within these areas, construction activities involving the extended idling of diesel equipment or vehicles will be prohibited to the extent feasible [as required by CCR Title 13, Section 2485(c)].  Track-out reduction measures will be used, such as gravel pads at project access points to minimize dust and mud deposits on roads affected by construction traffic, in accordance with the State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4).  All transported loads of soils and wet materials will be covered before transport, or adequate freeboard (space from the top of the material to the top of the truck) will be provided to minimize emission of dust during transportation in compliance with the SCAQMD Rule 403.

4. Environmental Consequences
42  Dust and mud that are deposited on paved, public roads due to construction activity and traffic will be promptly and regularly removed to reduce PM emissions [State Vehicle Code Section 23114, with special attention to Sections 23114(b)(F), (e)(2), and (e)(4)].  To the extent feasible, construction traffic will be scheduled and routed to reduce congestion and related air quality impacts caused by idling vehicles along local roads during peak travel times (consistent with the traffic control plan approved by the City of Colton Traffic Engineer).  Mulch will be installed or vegetation planted as soon as practical after grading to reduce windblown PM in the area. Note that certain methods of mulch placement, such as straw blowing, may themselves cause dust and visible emission issues and may require controls such as dampened straw [Caltrans Standard Specifications for Construction, Sections 18.1-02C (Dust Control Binders) and 18-1.03 (Construction – Dust Palliatives) or Greenbook equivalent].

4.2.2 Asbestos
The proposed Project is in San Bernardino County, which is among the counties listed as containing serpentine and ultramafic rock. However, the portion of San Bernardino County in which the proposed Project lies is not known to contain serpentine or ultramafic rock, according to the California Department of Conservation, Division of Mines and Geology (2000). Therefore, the impact from naturally occurring asbestos during Project construction would be minimal to zero. In the unlikely event that naturally occurring asbestos, serpentine, or ultramafic rock is discovered, SCAQMD will be notified per Section 93105, Title 17 of the CCR.

There is the potential for asbestos-containing materials (ACM) to be present in the existing bridge structure or in buildings on properties that would be acquired. If asbestos is found to be present in structures that would be modified as part of the Build Alternative, the certified asbestos abatement specialist would monitor the removal and disposal of the ACMs as they are uncovered. The contractor will be required to comply with Caltrans Standard Specifications Section 14-9.02 or Greenbook equivalent specification pertaining to air pollution control compliance with rules, regulations, ordinances, and statutes during renovation and demolition activities.

4.2.3 Lead
Lead is normally not an air quality issue for transportation projects unless the Project involves disturbance of soils containing high levels of aerially deposited lead, or painting or modification of structures with lead-based coatings. An aerially deposited lead (ADL) survey will be conducted to identify soils within the Project area containing high levels lead.

There is the potential for lead-based coatings in buildings on properties that would be acquired. If lead-based coatings are found to be present in structures that would be modified as part of the Build Alternative, the lead abatement specialist would monitor the removal and disposal of the lead-based coatings/soils as they are uncovered. The contractor will be required to comply with Caltrans Standard Specifications 14-9.02, 2015 or Greenbook equivalent specification pertaining to air

4.3 Long-Term Effects (Operational Emissions)
The purpose of the project is to provide safe connectivity between La Cadena and the Barton Road/Interstate 215 (I-215) interchange and to facilitate efficient access between Colton and Grand Terrace. The potential impact of the proposed Project on regional vehicle emissions was calculated using traffic data for the Project region and emission rates from the Emission Factor Model, Version 2017 (EMFAC2017).

The Project Area traffic for the existing Baseline, No Build Alternative, and Build Alternative were estimated using data from the Traffic Study Report (KOA 2020). The traffic data, along with the EMFAC2017 emission rates, were used to calculate the CO, reactive organic gases (ROG), NOx, PM10, and PM2.5 emissions for the existing condition (2019), opening year 2023, and horizon year 2045. The modeling results are summarized in Table 4-2 and are included in Appendix D.

4. Environmental Consequences
44 As Table 4-2 shows for the vehicle exhaust emissions in 2023, the No Build and Build Alternative emissions are all lower than the existing condition emissions, except for fugitive dust PM10 and PM2.5 emissions. Additionally, the Build Alternative for horizon year 2045 criteria pollutant emissions from vehicle exhaust are all less than the No Build Alternative emissions. The fugitive PM2.5 and PM10 emissions consist of tire wear, brake dust, and re-entrained road dust emissions that are purely related to the increased regional VMT. The slight increase in fugitive dust PM10 and PM2.5 emissions will not cause violations of the State PM10 and PM2.5 ambient air quality standards in the South Coast Air Basin. The proposed Project would not substantially contribute to or cause deterioration of existing air quality.

4.3.1 Carbon Monoxide Analysis
The methodology required for a CO local analysis is summarized in the Caltrans Transportation Project-Level Carbon Monoxide Protocol (CO Protocol), Section 3 (Determination of Project Requirements) and Section 4 (Local Analysis).

In Section 3, the CO Protocol provides two conformity requirement decision flowcharts designed to assist project sponsors in evaluating the requirements that apply to specific projects. The flowchart in Figure 1 (Appendix E of this report) of the CO Protocol applies to new projects and was used in this local analysis conformity decision. The following provides a step-by-step explanation of the flowchart. Each level cited is followed by a response, which in turn determines the next applicable level of the flowchart for the project (Garza et al., 1997).

The flowchart begins with Section 3.1.1:
 3.1.1. Is this project exempt from all emissions analyses? No.

Table 1 of the CO Protocol is Table 2 of 40 CFR, Section 93.126. The CO flowchart inquires whether the project is exempt. Such projects appear in Table 1 of the CO Protocol. The Build Alternative is not one of the exempt projects listed in Table 1 of the CO Protocol; therefore, the proposed Project is not exempt from all emission analyses.  3.1.2. Is the project exempt from regional emissions analyses? No.

Table 2 of the CO Protocol is Table 3 of 40 CFR, Section 93.127. The question attempts to determine whether the proposed Project is listed in Table 2. Projects that are included in Table 2 of the CO Protocol are exempt from regional conformity. Because the proposed Project would expand and add traffic lanes to an existing bridge, it is not exempt from regional emission analysis.

45  3.1.3. Is the project locally defined as regionally significant? No.

As noted above, the proposed Project would replace an existing two lane bridge with a widened two-lane surface road. Therefore, the proposed Project is not regionally significant.  3.1.4. Is the project in a federal attainment area?
No.

The proposed Project is within an attainment/maintenance area for the federal CO standard; therefore, the Project is subject to a regional conformity determination.  3.1.5. Are there a currently conforming Regional Transportation Plan (RTP) and Transportation Improvement Program (TIP)?
Yes.

Refer to Appendix A.
 3.1.6. Is the project included in the regional emissions analysis supporting the currently conforming RTP and TIP?
Yes.
