Rescue Plan Act (ARPA) funds to support the acquisition and operations of interim supportive housing at a motel.

This funding allocation allowed the City to revisit the potential acquisition of the Flamingo Motel as a longer-term replacement for the rooms currently leased by Yolo County at the Economy Inn. After several months of negotiations with the owner of the Flamingo Motel, an agreement on price and terms was reached on March 3, 2023.

ANALYSIS
The proposed terms for the City’s acquisition of the Flamingo Motel are outlined in the table below:

Purchase Price: $3,100,001
Deposit: City will make a non-refundable deposit of $310,000 (roughly 10 percent of the purchase price) upon execution of the Purchase and Sale Agreement.

Closing Date: 45-day escrow period with an outside closing date of May 30, 2023.

Cessation of
Operations/
Occupancy:

Owner will cease daily motel operations by the closing date, but will be permitted to occupy the property through at least June 30, 2023, at no cost (Project RoomKey residents from the Economy Inn will move to the property after the close of escrow), with a possible extension if the owner is in escrow to acquire their replacement residence. Owner has stated that there are no long-term occupants residing in the motel; staff will confirm as part of due diligence.

This report seeks authorization of delegated authority to the City Manager to prepare and execute a Purchase and Sale Agreement based on these terms, subject to the approval of the City Attorney.

A total of $3,350,001 is required to cover the purchase price ($3,100,001), due diligence and closing costs (estimated at $50,000), and an allowance for minor repairs to the property (estimated at $200,000). The proposed funding sources for these costs are $1,550,000 in one-time Measure E funds and $1,800,001 in onetime General Funds. About $1 million of the General Fund dollars proposed for this use will be replenished by a corresponding adjustment to the City’s expenditure plan for its ARPA funds, so the net impact to one-time General Funds from this transaction would be about $750,000. The funds required from the City for the proposed acquisition have been held in reserve as staff negotiated the transaction and applied to Yolo County for ARPA funding to support program operations.

Previous estimates for the operations of interim supportive housing at the property totaled $2,600,000 over a three-year period, which was the basis for the City’s ARPA funding request to Yolo County. It is expected that the County ARPA funds will be sufficient to be used exclusively to cover all the City’s expenses related to program operations and property management. The City will be able to achieve some operational efficiencies between the former Rodeway Inn and Flamingo Motel due to the properties’ proximity across the street from one another.

In addition to providing critically needed interim supportive housing for some of the most vulnerable homeless individuals in the community, the acquisition of the Flamingo Motel is another strategic property acquisition to advance the City’s longstanding goals for building an active city center. The property is located adjacent to the roughly 9-acre Grand Gateway development area, which is owned entirely by the City and is expected to include hundreds of housing units and other mixed commercial uses at buildout.

Environmental Considerations
Staff has determined that a Class 1 (Existing Facilities) and Class 32 (In-Fill Development Projects) Categorical Exemptions (pursuant to sections 15301 and 15332 of the CEQA Guidelines) are the appropriate level of review under CEQA for this document (See Attachment 14, Notice of Exemption). Class 1 consists of the operation, repair, maintenance, permitting, leasing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of the use beyond that existing at the time of the lead agency’s determination. Class 32 consists of projects characterized as in-fill development that are consistent with the general plan designation and zoning designation, occurs within the city limits, has no significant habitat value, would not result in significant effects related to traffic, noise, air quality or water quality, and may be served by all required utilities and public services.

Commission Recommendation
N/A
Strategic Plan Integration
The recommended actions address Homelessness and Communitywide Impacts, which is a current priority on 351 Flamingo Motel Acquisition
March 15, 2023

the City Council’s Strategic Plan.

Alternatives
The Council’s primary alternative to the recommended actions is to decline to purchase the motel. Staff strongly advises against this alternative because it will result in the near-term displacement of dozens of vulnerable residents of Project RoomKey, and it will disallow the City from making a strategic real estate investment on West Capitol Avenue.

Coordination and Review
The report was coordinated with the City Manager’s Office, the Finance Division, the Police Department, and the City Attorney’s Office.

Budget/Cost Impact
The $3,350,001 in costs related to the acquisition and rehabilitation of the property will be split between onetime Measure E funds ($1,550,000) and one-time General Funds ($1,800,001). These sources have been held in reserve by the City for this purpose as the proposed motel acquisition was negotiated and the interim housing program was being developed. A tabular summary of the sources and uses for the proposed acquisition is included below. The City previously secured $2.6 million in ARPA funds from Yolo County to cover the costs of interim housing operations, including property management, supportive services, maintenance, and utilities over a three-year period.

Source Amount
One-Time Measure E Funds $1,550,000
One-Time General Funds $1,800,001
Total Sources $3,350,001
Use Amount
Purchase Price $3,100,001
Minor Property Rehabilitation $200,000
Due Diligence and Closing Costs $50,000
Total Uses $3,350,001

Measure E Analysis
Project Description
This requested expenditure is to assist with real property acquisition to expand the City’s Homekey Program to provide interim housing for homeless individuals, or at risk of being homeless. The acquisition of the Flamingo Motel will be used to transition Project RoomKey participants currently being housed in West Sacramento motels and will serve as a longer-term replacement for the rooms currently leased by Yolo County. Funding for the acquisition includes $1,550,000 in one-time Measure E funds and $1,800,001 in one-time General Funds. About $1 million of the General Fund dollars proposed for this use will be replenished by a corresponding adjustment to the City’s expenditure plan for its American Rescue Plan Act (ARPA) funds, so the net impact to one-time General Funds from this transaction would be about $750,000.

Additionally, in 2022, the City requested and received $2.6 million from Yolo County’s ARPA funds to support the acquisition and operations of interim supportive housing at a motel.

Policy Context
“Homelessness and Communitywide Impacts” is a current priority on the City Council’s Strategic Plan and was a Top Priority Policy Management Agenda item in the Council’s 2019 Strategic Plan and was on the Management Agenda of the 2020 Strategic Plan. Lastly, voter-approved Measure E specifically listed “reducing community impacts of homelessness” as one of its programmatic uses.

Supplementary Funds
The proposed expenditure is for a program that will be partially funded by the City. Additional funding sources for the operation of the Flamingo Motel to expand the City’s Homekey Program include $2.6 million in Yolo County ARPA funds. This effort will, however, create fiscal as well as other benefits by continuing to provide medium-term housing for one of the most vulnerable populations. The expansion of the Homekey Program will also provide the City’s Homeless Manager with an additional resource to help West Sacramento residents escape homelessness.

While difficult to quantify, the project is also expected to create soft cost savings to the Police Department by reducing the amount of time spent on homeless-related enforcement activities.

Staff Costs
The proposed Measure E expenditure will not be used to cover any City staff costs. The funds will be used to pay costs associated with real property acquisition and minor rehabilitation.

Desired Outcome
The proposed Measure E expenditure is expected to mitigate and reduce the community impacts of homelessness. The program will provide interim housing for homeless individuals, or at risk of being homeless. Program participants will be indoors and safe from the dangers that they face from living outdoors. Additionally, program participants will receive supportive services including case management and housing navigation with the ultimate goal of placing program participants into permanent housing.

Theory of Change
The proposal’s outcomes are premised on two key assumptions: (1) the Homekey Program model will directly promote positive behavioral changes for participants by providing supportive services with a goal to achieve self-sufficiency and place them in permanent housing; (2) an increase in positive behavioral changes will further encourage participants to rebuild effective work habits, take on leadership opportunities, further their education, and ready themselves to reenter the workforce and housing through the support of a positive community.

There are two key risks to this vision: (1) the expansion of the Homekey Program fails to secure enough willing participants for the program, and (2) participants remain unresponsive to the 355
increase in positive behavior changes. To mitigate the first risk, the City’s Homekey Program has multiple entry points to the program. These entry points include: 1) existing Project RoomKey participants being housed in West Sacramento motels; 2) referrals from the West Sacramento Homeless Manager; and 3) referrals from partner relationships with other agencies in the City.

The following factors mitigate the second risk: (1) supportive services will be offered on-site to all Homekey Program participants with an ultimate goal of self-sufficiency and identifying a permanent housing alternative, and (2) homeless persons who engage in illegal behaviors will be subject to enforcement actions from the Police Department.

Acquisition Budget
Total cost for the acquisition of the Flamingo Motel is as follows:

Source Amount
One-Time Measure E Funds $1,550,000
One-Time General Funds $1,800,001
Total $3,350,001
* Includes $50,000 for closing/due diligence activities and $200,000 for minor rehab.

Performance Metrics
Homekey Program participants will be tracked using the Yolo County Continuum of Care (CoC) Health Management Information System (HMIS). The HMIS is used County-wide to track services individuals are receiving, individual’s health needs and is used for housing placement opportunities. Additionally, staff will maintain records on the following metrics:
 Number of Homekey Program participants being served
 Number of Homekey Program participations receiving supportive services  Number of Homekey Program participants who have moved into permanent housing  Number of Homekey Program participations who have gained employment  Number of Homekey Program participations who removed barriers to self-sufficiency Collectively, staff believes the analyses summarized above will provide the Council with ample information to review the program’s performance and assess its effectiveness. 356

ATTACHMENT [ ] Yes [ ] No [ ] Information [ ] Direction [ ] Action

OBJECTIVE
The purpose of this report is to provide background information necessary for City Council to consider and approve the environmental documentation and engineering design to advance both the I Street Bridge Replacement Project and I Street Bridge Deck Conversion for Active Transportation Project.

RECOMMENDED ACTION
Staff respectfully recommends that the City Council adopt Resolution 23-29:
1) Approving the CEQA Environmental Documentation and Findings and approving Engineering Design Plans for the I Street Bridge Replacement Project (Replacement Project); 2) Approving the CEQA Environmental Documentation and Findings and approving Engineering Design Plan for the I Street Bridge Deck Conversion for Active Transportation Project (Deck Conversion Project); and
3) Delegating authority to the City Manager to undertake certain actions to commence and complete all real property transactions in preparation for and in advance of construction of the Replacement Project and Deck Conversion Project.

BACKGROUND
The City of Sacramento in partnership with the City of West Sacramento, continues to work toward establishing new bridge crossings over the Sacramento River in line with the goals set forth in the 2003 Sacramento Riverfront Master Plan and the 2011 Sacramento River Crossings Alternatives Study. The Replacement Project will construct a new vertical lift bridge upriver from the existing historic I Street Bridge. Once completed the Cities will remove portions of the viaducts that currently provide motor vehicle access to the upper deck of the I Street Bridge and open the Sacramento and West Sacramento waterfronts to future open space, recreation, housing, and commercial development. The Deck Conversion Project will replace those motor vehicle ramps with Americans with Disabilities Act (ADA) compliant bicycle and pedestrian accessible ramps north and south of the existing historic bridge in West Sacramento, and north and east of the existing bridge in Sacramento. One ramp in Sacramento will allow for maintenance and public safety vehicle access. The timeline for both these projects anticipates construction completion in 2028.

Replacement Project
In accordance with the California Environmental Quality Act (CEQA), the Cities identified, disclosed, and considered the potential environmental impacts of the Replacement Project. The I Street Bridge Replacement Project Draft Environmental Impact Report (Draft EIR) was circulated for a 45-day public review and comment period from September 28, 2017, through November 12, 2017. The Final EIR explains why the project is being proposed; what alternatives were considered for the project; how the existing environment could be affected by the project; the potential impacts of each of the alternatives; and the proposed avoidance, minimization, and/or mitigation measures. The Final EIR contains both public and agency comments received during the public review period for the I Street Bridge Replacement Project Draft EIR, and responses to each of those comments.

California and federal noticing procedures were followed, and written comments received during the public review period on the Draft EIR were addressed in the Final EIR; California Public Resources Code (PRC), Sections 21000–21177).

The Lead Agency (the City of Sacramento) certified the Final EIR, before the West Sacramento City Council also approved the Replacement Project and adopted the EIR/EA on August 7, 2019; directing staff to proceed with final design and construction. Both the City of Sacramento and the City of West Sacramento used the Replacement Project EIR as the basis for adopting Findings that changes have been incorporated in the project 357 Consideration of Resolution 23-29 Approving the Environmental Documentation and Engineering Design Plans for I Street Bridge Replacement and I Street Bridge Deck Conversion for Active Transportation Projects March 15, 2023

to avoid or substantially lessen significant environmental effects or identify specific considerations which make alternatives infeasible. These environmental documents were developed and made available for review at the City of West Sacramento’s Community Development Department, at the City of Sacramento, and through the City of Sacramento website. Documents included:
 The I Street Bridge Replacement Project Draft EIR-EA
 The I Street Bridge Replacement Project Draft EIR-EA Appendices  The I Street Bridge Replacement Project Draft EIR-EA Technical Studies  Final EIR/Environmental Assessment with Finding of No Significant Impact - Volume 1  Final EIR/Environmental Assessment with Finding of No Significant Impact - Volume 2 Deck Conversion Project
A feasibility study evaluating the potential to preserve and transform the top deck of the historic bridge (1911) into a safe, accessible bicycle and pedestrian facility after construction of the Bridge Replacement Project was completed and published March 29, 2019. This study included a robust community engagement process, including the I Street Bridge Lantern Festival attended by over 3000 members of the Sacramento and West Sacramento community. The feasibility study served as the basis for environmental analysis and preliminary engineering (30% design) that was initiated June 2020 and completed February 2023. The effort included significant coordination with the City of Sacramento, Public Utilities Commission, and Union Pacific Railroad, who’s representatives participated in both on-site and online design coordination meetings.

ANALYSIS
Replacement Project
Since October 19, 2022, Staff and the project design team has reviewed constraints associated with the Replacement Project. There have been a variety of changes in policy since circulation of the Draft EIR in 2017, and certification of the Final EIR and Project approval in 2019:
1) As of July 1, 2020, SB 743 began requiring cities to evaluate transportation impacts with metrics that promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks, and a diversity of land uses - allowing staff to consider other state goals, like reducing greenhouse gas (GHG) emissions, developing multimodal transportation, preserving open spaces, and promoting diverse land uses and infill development over reducing traffic levels. Previously, level of service at road intersections was the primary metric for evaluating traffic impacts. 2) After the initial evaluation of access alternatives to 2nd Street, it was determined that the project will be required to reconstruct the levee where the bridge approach will land. Therefore, modifications that push access to 2nd Street further east toward the levee can now be considered. 3) The Washington Specific Plan is currently being updated to incorporate policies identified in the Washington Realized area plan. As such, previous circulation plans will be revisited by the City Council that enable staff to consider revised road network implementation associated with the I Street Bridge Replacement Project.

Modified 2nd Street Access Design
City staff and the project engineering team explored options under the City Council directive of further reducing potential impacts associated with access to 2nd Street. A revised engineering design was developed [Attachment 1, Appendix A] that accomplishes the following:
a) No housing relocations and no acquisition of developed residential properties will be required; however vacant properties adjacent to the Sacramento River levee, a portion of the vacant property located on the corner of 2nd and C Street, and previously identified property south of C Street remain impacted by the project, as discussed in the Final EIR.
b) Introduction of a 500-foot separation from the existing intersection of 3rd and C Streets to the proposed intersection of 2nd and C Street. The increased distance between intersections provides sufficient distance to offset potential traffic impacts associated with turning movements and merging. c) A cul-de-sac design consistent with city standards, allowing fire department access and turn around space for fire apparatus. In addition, the distance from the new cul-de-sac to the new terminus of existing 2nd Street would be approximately 150-feet and determined acceptable by fire department standards. d) A residential turning circle with minimum width of 20-feet encircling an approximately 22-foot landscaped median provides sufficient turning space for motor vehicles and solid waste/recycling trucks, allowing for continued curbside service and vehicle access. No parking signs will be installed within the turning circle to ensure unrestricted turning movement. This design will be further reviewed through the 65% and 100% engineering design process.

Consideration of Resolution 23-29 Approving the Environmental Documentation and Engineering Design Plans for I Street Bridge Replacement and I Street Bridge Deck Conversion for Active Transportation Projects March 15, 2023

e) Revised lane configuration on the bridge approach in West Sacramento to allow for left turns into and from the realigned 2nd Street, as well as a westbound right turn taper into 2nd Street. A supplemental traffic analysis was conducted with development of the concept that confirms the addition of these design elements will yield no significant traffic operational impact over the existing Project. f) A driveway cut and right in/right out access will be maintained in the current location of the existing proposed alley as indicated in the Project EIR, allowing a secondary access for the property located at the corner of 2nd and C Street.

On November 16, 2022, the City Council provided the conceptual approval of the preliminary engineering design modifications including:
1) In accordance with 14 California Code of Regulations (CCR) Sections 15162-15164, after an EIR has been certified for a project, a Lead Agency for a discretionary action related to that project must determine what additional environmental documentation may be necessary, if any, and prepare the appropriate level of documentation for consideration when approving the project. An Addendum to the Certified EIR [Attachment 1] was subsequently prepared and the City Council is now being asked to consider the additional environmental documentation and findings included in that Addendum, along with the previously prepared Final EIR.
2) Modifications to the Washington Realized area plan to conform with the revised 2nd Street access design, and inclusion of these design modifications in the forthcoming Washington Specific Plan was conceptually approved by the City Council. Staff is seeking final approval from the City Council with this report.
3) A residential in-road landscape island as a non-standard road design feature. The City Council is being asked with this report to submit final approval of that design.

Deck Conversion Project
The Public Draft Initial Study/Proposed Mitigated Negative Declaration (IS/MND) was circulated over an extended public comment period from October 11, 2022, through November 14, 2022. A Notice of Intent to adopt the MND was published in accordance with CEQA (14 CCR 15072). Comments were received from the Sacramento Metropolitan Air Quality Management District, California Department of Fish and Wildlife, Department of Toxic Substances Control, Sacramento Municipal Utility District (who provides electricity service to the bridge), and the Central Valley Regional Water Quality Control Board following review of the IS/MND. A copy of each comment letter and discussion of the comments contained are attached with this agenda report. [Attachment 4]
The Mitigated Negative Declaration (MND) [Attachment 2] and Mitigation Monitoring Plan (MMP) [Attachment 3] for the Deck Conversion Project were prepared for City Council adoption. The MMP was prepared in accordance with PRC section 21081.6 and 14 CCR 15097 which require public agencies to establish monitoring or reporting programs approved by a public agency whenever approval requires adoption of an MND. The intent of the MMP is to aid the City of West Sacramento in its implementation and monitoring of mitigation measures.

Project Funding and Grant Status
Replacement Project
The Preliminary Engineering is complete for the new bridge spanning between C Street in West Sacramento and Railyards Boulevard in Sacramento. Final Engineering Design (PS&E) and Right of Way (R/W) funding has been authorized by the California Department of Transportation (Caltrans) and obligated in the amount of $26,589,168. Upon completion of the final design and R/W acquisitions, the Replacement Project will be “shovel ready” for construction. Although a majority of funding for the bridge has been secured through State and federal grants, there is still a significant amount of funding needed for construction. Sacramento and West Sacramento staff are working diligently to secure the necessary federal grant funding through various sources, including the Bridge Improvement Program to complete the project in 2028.

Deck Conversion Project
On June 15, 2022, the Community Development Transportation Division submitted a California State Active Transportation Program grant to complete full construction of ramp improvements in both Sacramento and West Sacramento, and associated paving, striping, and various amenities including landscaping, interpretive signs, and lighting. On December 8th, the California Transportation Commission awarded the City of West Sacramento $16.029 million in grant funding to complete the project. Making the $22.561 million project fully funded through construction. This grant, and other grant funds received for this project and the Replacement Project cannot be used for any other purpose than for the construction of these bridges and were awarded to improve public safety, improve mobility, reduce motor vehicle congestion, reduce vehicle miles traveled and GHG emissions from motor 359
Consideration of Resolution 23-29 Approving the Environmental Documentation and Engineering Design Plans for I Street Bridge Replacement and I Street Bridge Deck Conversion for Active Transportation Projects March 15, 2023

vehicle use, to enhance connectivity between the cities, to improve access to the Sacramento Valley Station regional transportation hub and Amtrak, to promote recreation and public health, and improve economic development within an SB 535 designated low-income, disadvantaged community zone.

With City Council approval of the MND and MMP, staff will initiate the final engineering design phase for the Deck Conversion in Mid-2023. Staff is working closely with the City of Sacramento as the construction schedule will be largely dependent upon the continued progress on the new C-Street/Railyards Bridge (Replacement Project) which is anticipated to be completed in 2028.

Initiating Right of Way Activities
The Replacement Project, upon receiving formal approval for the design modification and Addendum from the City Council, will be authorized to complete final engineering design and enter the R/W project development phase in West Sacramento. Activities have already been approved and federal funding allocated by Caltrans for this phase. Similarly, the Deck Conversion Project will be entering into the final engineering design phase this spring, and we anticipate completion in as little as 12 months.

Prior to initiating construction of either project, the City must procure all necessary property rights required for construction of the project by the City Council delegating authority to the City Manager to acquire real property rights with the adoption of Resolution 23-29. Staff will be seeking authorization to initiate R/W activities immediately following City Council action for the Replacement Project, and within approximately 18 months for the Deck Conversion Project.

Environmental Considerations
Replacement Project
An Addendum to the certified EIR for the Replacement Project was prepared in accordance with City Council direction received on November 16, 2022, to revise the project’s design for 2nd Street. Approval of the design modification by the City Council (Lead Agency) is a discretionary action subject to CEQA and an addendum is required if minor technical changes or modifications to the proposed project occur (14 CCR 15164). The Addendum documents the revised project design and explains the decision not to prepare a subsequent EIR pursuant to 14 CCR 15162. Based on the findings in the environmental checklist included in the Addendum, no subsequent EIR is necessary for the project.

On February 14, 2023, Caltrans completed their consideration of the design modification and revalidated the Finding of No Significant Impact under the National Environmental Policy Act. No further environmental action at the federal level is required.

Deck Conversion Project
In accordance with CEQA, the City (Lead Agency) must identify, disclose, and consider the potential environmental impacts of the project, and adopt the environmental document (MND) and mitigation measures (MMP) before proceeding with final design and construction. The West Sacramento City Council is the Lead Agency for this action. Based on the information in the attached Initial Study for the I Street Bridge Deck Conversion for Active Transportation project and in the entire record, the City of West Sacramento finds that although the proposed project could have a significant impact on the environment, mitigation measures have been incorporated into the project that reduce these impacts to less-than-significant levels.

Commission Recommendation
Information on the environmental process including the environmental documents, design plans, and workshop results on the Replacement Project were made available to the Transportation, Mobility and Infrastructure Commission and presented at their regular meeting on July 1, 2019. The Commission recommended approval of the Environmental Impact Report (EIR) and preliminary plans for the Replacement Project and recommended staff continue to coordinate development of the Replacement Project in conjunction with the Deck Conversion Project. The Commission was notified of both the November 14, 2022, Community Meeting and the November 16, 2022, City Council meeting, and members of the Commission were present at the Community meeting. In addition, the Commission has been kept informed on the progress of the Deck Conversion Project through its inception beginning in 2016 and has received regular updates though the environmental and preliminary engineering design process. As these two projects continue to advance, additional Commission input and community engagement will be conducted in accordance with City policies. 360
Consideration of Resolution 23-29 Approving the Environmental Documentation and Engineering Design Plans for I Street Bridge Replacement and I Street Bridge Deck Conversion for Active Transportation Projects March 15, 2023

Strategic Plan Integration
These projects directly address the guiding principle of Mobility & Connectivity of the West Sacramento Strategic Plan. In addition, the projects are identified in the Policy Agenda of the current Strategic Plan.

Coordination and Review
Replacement Project
This report, policy considerations, and design implications associated with the proposed engineering design modification for the Replacement Project were subject to extensive review by the City Attorney, Fire Marshall, City Manager’s Office, Finance, WSAFCA, Community Development Department, Economic Development and Housing Department, Capital Projects Department, the City of Sacramento, and the Mark Thomas engineering design team and their subconsultants. All parties have contributed toward development of the recommended action.

Deck Conversion Project
The Deck Conversion Project is a multi-agency, multi-departmental effort that has received extensive collaboration and community engagement from the initial feasibility study through preliminary engineering and environmental review. Engineering design was coordinated with the Public Utilities Commission and Union Pacific Railroad, who has executed an agreement to review and coordinate on the project with the City of West Sacramento.

Alternatives
As an alternative, the City Council may choose to modify or deny the recommended actions. Additionally, the Council may choose to continue these items to a future date. However, as the City of West Sacramento is the Lead Agency under CEQA for the approval of the addendum to the EIR for revisions to the Replacement Project preliminary design as well as for adoption of the I Street Bridge Deck Conversion for Active Transportation Project MND and approval of the Deck Conversion Project, neither project may advance to subsequent phases without the recommended action.

Budget/Cost Impact
The recommendations in this Agenda Report do not result in any financial impact to the City. Modifications to the approved engineering plans and the addendum to the certified EIR for the Replacement Project are funded under the current executed Cooperative Agreement with the City of Sacramento to fund activities under the Final Design (PS&E) and Right of Way project development phases.

Both projects are programmed in the current West Sacramento Capital Improvement Program.

Introduction
Purpose of this Addendum
In 2022, West Sacramento city staff and the consultant engineering team explored revisions to the previously approved I Street Bridge Replacement Project (project) under the directive of the West Sacramento City Council to further reduce potential impacts associated with the project’s design for access to 2nd Street. A revised design within West Sacramento was developed for the project that would eliminate the need to acquire residential property. Approval of the design modification by West Sacramento City Council is a discretionary action subject to the California Environmental Quality Act (CEQA); the City of West Sacramento is the CEQA lead agency. Under CEQA, an addendum to a certified Environmental Impact Report (EIR) is needed if minor technical changes or modifications to the proposed project occur (14 California Code of Regulations [CCR] 15164). This addendum documents the revised project design in West Sacramento and explains the decision to not prepare a subsequent EIR pursuant to 14 CCR 15162. Based on the findings in the environmental checklist (Chapter 3, below) and as provided in Chapter 4, Conclusion, no subsequent EIR is necessary for this project.

State CEQA Guidelines
Guidelines for implementation of CEQA are in Title 14 of the CCR. As described in 14 CCR 15164, a lead or responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary, but none of the of conditions identified in 14 CCR 15162 calling for preparation of a subsequent EIR have occurred. 14 CCR 15162(a) states:
(a) When an EIR has been certified or a negative declaration adopted for a project, no subsequent EIR shall be prepared for that project unless the lead agency determines, based on substantial evidence in the light of the whole record, one or more of the following conditions are applicable:
(1) Substantial changes are proposed in the project which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; (2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or (3) New information of substantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the negative declaration was adopted, shows any of the following:
(A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration;
371
City of West Sacramento Introduction
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 1-2 February 2023
(B) Significant effects previously examined will be substantially more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or alternative; or (D) Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.

If any of the triggers set forth above occur, the lead agency would be required to prepare a subsequent EIR, unless “only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation,” in which case a “supplement to an EIR” would suffice (14 CCR 15163[a]). When none of the conditions in Section 15162(a) or 15163 are present, meaning there are no grounds for either a subsequent EIR or a supplement to an EIR, a lead agency must prepare an addendum pursuant to 14 CCR 15164, explaining why “some changes or additions” to the certified EIR “are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred.” An addendum need not be circulated for public review (14 CCR 15164[c]); however, an addendum is to be considered by the decisionmaking body along with the Final EIR or adopted negative declaration prior to making a decision on the project (14 CCR 15164[d]).
2019 Certified Environmental Impact Report
The City of Sacramento, the City of West Sacramento, and the California Department of Transportation (Caltrans) each approved the I Street Bridge Replacement Project which includes construction of a new bridge over the Sacramento River to replace the vehicle crossing that is currently accommodated by the existing I Street Bridge and removal of a series of functionally obsolete or structurally deficient bridges (i.e., approach structures).

A joint Environmental Impact Report/Environmental Assessment (EIR/EA) was prepared for the project to comply with CEQA and the National Environmental Policy Act (NEPA). The City of Sacramento was the lead agency under CEQA, and the California Department of Transportation was the lead agency under NEPA.

On June 25, 2019, the City of Sacramento, certified the Final EIR (FEIR) (City of Sacramento 2019), adopted Findings, a Statement of Overriding Considerations, and a Mitigation Monitoring Plan before approving the project (Resolution 2019-0276). On August 7, 2019, the City of West Sacramento, as a CEQA responsible agency, used the FEIR as the basis for adopting its own Findings, Statement of Overriding Considerations, and a Mitigation Monitoring Plan for the components of the project under its discretion and the mitigation that it will be responsible for carrying out, and approved the project (Resolution 19-77).

Project Description
Project Location
The I Street Bridge Replacement Project is located over the Sacramento River between the cities of Sacramento and West Sacramento, approximately 1,000 feet north of the existing I Street Bridge (2019 Certified FEIR Figure 1-1, in Appendix A). The project limits, starting within Sacramento, consist of Railyards Boulevard from 200 feet east of Bercut Drive on the east, continuing west over the Sacramento River into West Sacramento along C Street, crossing 2nd Street, and terminates approximately 100 feet west of the 5th Street intersection. The project limits in Sacramento also extend along Bercut Drive approximately 500 feet north of Railyards Boulevard, along Jibboom Street 550 feet north of Railyards Boulevard and 300 feet south of Railyards Boulevard, along 3rd Street 50 feet north and south of C Street, along 4th Street 50 feet north and south of C Street, and along 5th Street 50 feet north and south of C Street. The total length of the project is approximately

0.42 mile (2,200 feet) along C Street and Railyards Boulevard (2019 Certified FEIR:1-1).

Project Summary
The project would construct a new vertical lift bridge over the Sacramento River between Sacramento and West Sacramento approximately 1,000 feet north of the existing historic I Street Bridge. Once construction of the new bridge and roadways is completed and traffic is diverted to them, portions of the viaducts that currently provide motor vehicle access to the upper deck of the I Street Bridge from both directions would be demolished and removed. The existing I Street Bridge over the Sacramento River would remain in place. A detailed description of the I Street Bridge Replacement Project is in Chapter 1 of the 2019 Certified FEIR. Appendix A includes Figure 1-2 from the 2019 Certified FEIR, which depicts the project. The summary presented here focuses on the project design elements in West Sacramento that are relevant to the proposed design modifications.

The 2019 Certified FEIR states that between the bridge touchdown location along C Street and the 4th Street/C Street intersection in West Sacramento, the roadway would consist of one westbound travel lane, two eastbound travel lanes (the two eastbound travel lanes would taper down to one eastbound lane east of the 3rd Street intersection), a center left-turn lane, on-street Class II bike lanes, on-street parking along the north side of the roadway, and sidewalks along both sides of the roadway. Along C Street between 4th Street and 5th Street, the roadway would consist of one travel lane in each direction, left-turn lanes, on-street Class II bike lanes, and sidewalks along both sides of the road. All of the improvements through this section would be accommodated within the existing roadway limits.

The new C Street alignment in West Sacramento, as described in the 2019 Certified FEIR, would cut off access to four residential parcels and one multifamily parcel located along 2nd Street, north of C Street. The project would also remove access to 2nd Street south of C Street and would create a cul-de-sac on the east-west portion of 2nd Street that connects to 3rd Street. To restore residential access, the project described in the 2019 Certified EIR would construct a new residential connection to C Street approximately 150 feet east of the 3rd Street intersection that would continue north 374
City of West Sacramento Project Description
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 2-2 February 2023
approximately 300 feet. The new connection would then make a 90-degree left turn and connect to 3rd Street approximately 300 feet north of C Street. The design described in the 2019 Certified FEIR would require right-of-way acquisition from seven individual parcels and removal of three structures: two individual residences (one on Assessor’s Parcel Number (APN) 010-101-010, and the other on APN 010-101-004), and apartment building that supports one individual apartment on APN 010-101-013 (2019 Certified FEIR:1-7).

Project Design Modifications
The proposed revisions to the project are entirely in West Sacramento and are bounded by C Street to the south, B Street to the north, 3rd Street to the west, and the landward toe of the west bank Sacramento River levee to the east. No changes to the project outside of this area are proposed.

The revised design (see drawing in Appendix A) provides access to 2nd Street by the creation of a cul-de-sac and residential turning circle. The need for housing relocations and acquisition of developed residential properties would be eliminated. Vacant properties adjacent to the Sacramento River levee, a portion of the vacant property located on the corner of 2nd and C Street, and previously identified property south of C Street would remain impacted.

A new access to 2nd and C Street would be created 500 feet east of the intersection of 3rd and C Street, an increased intersection separation of about 100 feet from existing conditions to provide sufficient distance to offset potential traffic impacts associated with turning movements and merging. The new access would descend on a fill slope roughly northward from the bridge approach at a grade consistent with the Americans with Disabilities Act to connect to the existing elevation of 2nd Street.

The cul-de-sac design would be consistent with city standards and would allow fire department access and turn-around space for fire apparatus. In addition, the distance from the new cul-de-sac to the new terminus of 2nd Street would be approximately 150 feet, acceptable by fire department standards.

The cul-de-sac would have a residential turning circle with minimum width of 20 feet encircling an approximately 22-foot landscaped median. The turning circle would provide sufficient turning space for motor vehicles and solid waste/recycling trucks, allowing for continued curbside service and vehicle access. No-parking signs would be installed within the turning circle to ensure unrestricted turning movement.

The lanes on the western bridge approach would be reconfigured to allow for left turns into and from the realigned 2nd Street and a westbound right turn taper into 2nd Street.

Required Discretionary Actions
Project design modifications will require West Sacramento City Council approval of the following items.
1) Approval of a residential in-road landscape island as a non-standard road design feature. 375
City of West Sacramento Project Description
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 2-3 February 2023
2) Modifications to the City Council approved Washington Realized area plan to conform with the proposed revision to the 2nd Street access.
3) Approval of the project, as modified from the project approved on August 7, 2019, after consideration of environmental analysis consistent with CEQA.

In accordance with CEQA Guidelines in 14 CCR Sections 15162-15164, after an EIR has been certified for a project, a lead agency for a discretionary action related to that project must determine what additional environmental documentation may be necessary, if any, and prepare the appropriate level of documentation for consideration when approving the project. The City Council will be asked to consider the additional environmental analysis in this addendum along with the 2019 Certified FEIR prior to giving final approval to the project modifications. 376

Analysis and Findings
Introduction
CEQA Guidelines Sections 15162 through 15164 (14 CCR 15162 – 15164) specify the criteria for determining the appropriate level of additional environmental documentation, if any, to be completed when there is a previously Certified FEIR for a project for which a subsequent discretionary action is required.

The checklist and analysis in this chapter were developed to assist the City of West Sacramento with the evaluation of the environmental factors addressed under CEQA to determine if the design modifications would result in significant impact conclusions different from those identified in the 2019 Certified FEIR.

Environmental Checklist
The column titles of the Appendix G State CEQA Guidelines checklist were modified from the Appendix G presentation to help answer the questions to be addressed pursuant to Public Resources Code (PRC) Section 21166 and 14 CCR 15162 through 15164. The checklist tables in each section are followed by a summary discussion of the 2019 Certified FEIR analysis of that environmental topic and a qualitative consistency evaluation of the project design modifications in West Sacramento, to document how the potential impacts from the modifications compare to the impacts evaluated in the 2019 Certified FEIR. The titles of adopted mitigation measures from the 2019 Certified FEIR that apply to the revised project to reduce a significant impact are listed. Page references are from the 2019 Certified FEIR. The checklist includes the following questions.

Do Proposed Changes or New Circumstances Involve New Significant Impacts or Substantially More Severe Impacts?
Any New Information of Substantial Importance?
Prior Environmental Documents Mitigations Address Impacts? A “No” answer does not necessarily mean that there are no potential impacts relative to the environmental category, but that there is no change in the condition or status of the impact as it was analyzed and addressed in the 2019 Certified FEIR.

An “N/A” under the column header “Prior Environmental Documents Mitigations Address Impacts?” means that no mitigation was identified for the impact in the 2019 Certified FEIR and no additional mitigation is needed for the proposed project. A “Yes” in this same column means the mitigation measure(s) identified in the 2019 Certified FEIR address the effects of the project, and the proposed design modifications. The titles of applicable 2019 Certified FEIR adopted mitigation measures are listed following the discussion of the issue area.

Discussion
The 2019 Certified FEIR identified the largest visual change and significant visual impact associated with the project as the introduction of a new bridge across the river that could be seen from various locations. The 2019 Certified FEIR also described impacts related to levee and roadway modifications, and removal of viaduct structures, as not greatly altering the quality of views and visual resources. The proposed design modifications do not change these project elements and the mitigation adopted to reduce impacts to less-than-significant levels are still applicable.

The 2019 Certified FEIR identified visual impacts to a small subset of the larger viewer groups affected by the 2nd Street access changes in West Sacramento. For the residential properties on 2nd Street, the most visibly noticeable changes that would result from the project described in the 2019 378
City of West Sacramento Analysis and Findings
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 3-3 February 2023
Certified FEIR would be the new bridge itself, the new fill slopes needed to support the new alignment of C Street where it shifts to the north to connect to the new bridge, and the new access road located at the western ends of the properties where property acquisition was required. The design modifications proposed would change the shape of the fill slope located on the north side of C Street at the western bridge approach to contain a new descending access road to 2nd Street. The northward sloping fill would slope to connect to 2nd Street, unlike the original project design and would be visually similar in scale to the original visual change caused by the project. The modified design would also introduce a cul-de-sac and landscaped residential turning circle on the existing paved 2nd Street alignment. A beneficial change of the modified design is the elimination of the western access road and elimination of acquisition of portions of residential parcels.

The 2019 Certified FEIR also identified a significant impact resulting from vegetation removal. The modified design does not change the area of cottonwood riparian forest affected by the project and reduces by approximately 20 the number of residential trees that would be removed through modifying the original design for 2nd Street access. The revised project design is within ruderal woodland and adjacent to developed land. Mitigation adopted to reduce the visual change from the loss of vegetation remains applicable to reduce the impact to a less-than-significant level.

The 2019 Certified FEIR identified the creation of a substantial source of nighttime light and glare that could negatively affect nighttime views in the area as a significant impact. New bridge, roadway, and intersection lighting could include LED lighting for security and safety purposes. Both the access road design in the 2019 Certified FEIR and the modified design would be lit following city street lighting standards. No changes to bridge lighting are proposed and the mitigation adopted is still applicable to reduce the significant impact to a less-than-significant level.

Applicable Mitigation Measures Adopted for 2019 Certified FEIR Implement Project Landscaping
Apply Minimum Lighting Standards
Conclusion
Revisions to the project in West Sacramento and/or new circumstances relevant to the project would not, as compared to the 2019 Certified FEIR, result in new significant impacts relating to aesthetics, or significant impacts that are substantially more severe than impacts previously disclosed. No new mitigation measures would be required. No new information or changes under the proposed project are known which would affect this conclusion. Therefore, the conclusions of the 2019 Certified FEIR remain valid, and no further analysis is required. 379

The 2019 Certified FEIR identified significant air quality impacts related to emissions from both project construction and project operation. Temporary construction emissions would result from grubbing/land clearing, grading/excavation, drainage/utilities/sub-grade construction, paving activities, bridge demolition and erection, and construction worker commuting patterns.

Construction of the modified project design would not add to the overall duration of project 381

I Street Bridge Replacement Project 3-6 February 2023
construction activities, move construction activities closer to sensitive receptors, or require the use of larger or different equipment that could cause greater levels of emissions. The adopted mitigation remains applicable to reduce impacts to less-than-significant levels.

Regarding long-term air quality impacts associated with motor vehicles operating on the roadway network, predominantly those operating in the project vicinity, the 2019 Certified FEIR found that the project would result in a negligible change in emissions compared to the No Build Alternative. No mitigation was required. The revised design does not change the volume of traffic using the bridge or approach roadways and does not locate traffic closer to existing land uses. A supplemental traffic analysis conducted for the revised design confirms no significant change in traffic operational impacts (Fehr and Peers 2022). Therefore, the revised project would not worsen long-term air quality associated with project operation.

The 2019 Certified FEIR describes how the project could result in direct and indirect impacts on specific special-status species including valley elderberry longhorn beetle, western pond turtle, white-tailed kite, Swainson’s hawk, pallid bat, western red bat, purple martin, other migratory birds, other bat species, Sacramento River winter-run Chinook salmon, CV spring-run Chinook salmon, CV fall- and late fall–run Chinook salmon, CV steelhead, the Southern DPS of North American green sturgeon, delta smelt, longfin smelt, Sacramento splittail, Pacific lamprey, and river lamprey. 383
City of West Sacramento Analysis and Findings
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 3-8 February 2023
Impacts were found to be significant and adopted mitigation measures would reduce to less than significant levels impacts for all but purple martin in Sacramento. The 2019 Certified FEIR found that impacts on purple martin could not feasibly be reduced to less-than-significant levels and were therefore unavoidable. The revised project design in West Sacramento is within a ruderal woodland land cover type in the project area and is adjacent to developed land. The disturbance area for the modified design is similar in scale to the project analyzed in the 2019 Certified FEIR. Mitigation adopted to reduce impacts on special-status species remains applicable to reduce the impact to a less-than-significant level.

The 2019 Certified FEIR describes the loss of cottonwood riparian habitat that would result from clearing existing forest vegetation for construction of the project, a significant impact. The proposed design modifications are within a ruderal woodland area north of C Street, which is not a sensitive natural community type. Revisions to the project design do not change the impacts to riparian habitat or other sensitive natural communities.

The 2019 Certified FEIR discusses how the project would result in significant permanent and temporary impacts on non-wetland waters, the Sacramento River. The project design modifications are west of the river and would not change project impacts on the river.

The 2019 Certified FEIR describes how the movement of fish species present in the Sacramento River could be affected by short-term work activities occurring in or adjacent to the river channel, resulting in a significant impact. The project design modifications are west of the river and west of the western river levee and would not change project impacts on the movement of fish in the river.

The 2019 Certified FEIR notes that construction of the project would result in the removal of up to 22 heritage trees in the City of Sacramento and 45 heritage trees in the City of West Sacramento.

Trees would be removed for the construction of abutments for the two fixed-span bridge approach structures on both the City of Sacramento and City of West Sacramento sides, the bikeway along Jibboom Street in Sacramento, and the C Street connection to 3rd Street in West Sacramento. The modified design for access to 2nd Street reduces the number of trees that would be removed in West Sacramento by recreating the access in an area of ruderal woodland with few native trees. The reduction in the loss of protected trees is a beneficial effect of the project design modification.

The Yolo Habitat Conservation Plan/Natural Community Conservation Plan was not approved or in effect at the time the EIR for the project was prepared and circulated. Consultation for federally listed species was led by Caltrans and the U.S. Fish and Wildlife Service and National Marine Fisheries Service issued Biological Opinions that address project impacts on delta smelt and valley elderberry longhorn beetle (USFWS) and Sacramento River winter-run Chinook salmon, Central Valley spring-run Chinook salmon, Central Valley steelhead, and the Southern distinct population segment of North American green sturgeon (NMFS). Habitat for these species is not located in the ruderal woodland land cover type where the modified design is located.

The 2019 Certified FEIR analyzed impacts to two historic era built-environment resources within the project area that are considered historical resources for the purposes of CEQA: the I Street Bridge and a segment of the Sacramento River East Levee (P-34-000490). No significant impacts to the Sacramento River East Levee were identified however potentially significant impacts to the I Street Bridge associated with the removal of the roadway approach structures leading up to the bridge were described. The 2019 Certified FEIR also discussed potentially significant impacts to the one archaeological resource identified, CA-SAC-658H on the east bank of the Sacramento River. The proposed design modifications are located north of C Street in West Sacramento and would not change impacts to the I Street Bridge or resources located in Sacramento.

The 2019 Certified FEIR also noted that it is possible that previously unknown archaeological resources or human remains could be uncovered during ground-disturbing construction activities and that disturbance could result in a significant impact. The modified project design in West Sacramento does not change the potential to uncover previously unknown resources or remains.

The mitigation measures adopted to reduce this impact to less-than-significant levels are still applicable.

Impacts of the project on energy resources were not evaluated as a separate topic area in the 2019 Certified FEIR because at that time energy was not evaluated on the CEQA Checklist. Consequently, the 2019 Certified FEIR did not identify impacts to energy resources in the CEQA discussion.

Impacts to utilities were evaluated and found to be less than significant, and no mitigation was required. Energy was analyzed for the purposes of NEPA (see page references in table above) and the project was found to not result in substantial energy impacts. During operation of the project, the 2019 Certified FEIR found that the project would improve overall transportation network performance compared to no build conditions, which would improve fuel efficiency.

Discussion
The 2019 Certified FEIR found that the project would not result in impacts related to earthquake faults, seismic activity, landslides, or soil stability. It documented that compliance with the appropriate building regulations and Caltrans’ seismic design criteria would ensure that project features are designed for existing geologic and soil conditions and to appropriately withstand seismic activity so as to not cause direct or indirect effects related to seismic events. The modified design in West Sacramento will also comply with the appropriate building standards and regulations. The modified design will also comply with erosion-related requirements applicable to the project to ensure that construction activities do not result in significant erosion.

The 2019 Certified FEIR described the paleontological sensitivity of the geologic unit that underlies the project site as low. However, it is possible that a lower portion of the unit could contain paleontological resources. Earth-disturbing (i.e., excavation and grading) construction activities could damage fossils if present in the project area. Substantial damage to or destruction of 389
City of West Sacramento Analysis and Findings

significant paleontological resources as defined by the Society of Vertebrate Paleontology would be a significant impact. Modifications to the project design do not require additional or deeper ground excavation or grading and mitigation adopted to reduce impacts to less-than-significant levels are still applicable.

Applicable Mitigation Measures Adopted for 2019 Certified FEIR Educate Construction Personnel in Recognizing Fossil Material Stop Work if Substantial Fossil Remains Are Encountered during Construction Conclusion
Revisions to the project in West Sacramento and/or new circumstances relevant to the project would not, as compared to the 2019 Certified FEIR, result in new significant impacts relating to geology, soils, or paleontological resources, or significant impacts that are substantially more severe than impacts previously disclosed.

The 2019 Certified FEIR analyzed potential greenhouse gas (GHG) emissions that could result from both construction and operation of the project. The analysis found that construction activities would generate short-term emissions of carbon dioxide, methane, and nitrogen dioxide from the use of equipment (e.g., graders) and on-road vehicles (e.g., employee commuter cars) and that the anticipated GHG emissions were less than significant. Construction of the modified project design 390
City of West Sacramento Analysis and Findings
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 3-15 February 2023
would not add to the overall duration of project construction activities or require the use of larger or different equipment that could cause greater levels of emissions. The impact would remain less than significant.

The 2019 Certified FEIR modeled operational emissions using California Air Resources Board’s EMFAC model. The results are presented in 2019 Certified FEIR Tables 3-2 and 3-3. Compared to the No Build Alternative, the project would result in negligible changes in GHG emissions (i.e., less than a

0.1-percent increase or even a decrease under some analysis conditions). Relative to existing conditions, however, the 2019 Certified FEIR found that project would result in substantial emissions reductions, predominately due to improvements in exhaust emissions. The revised design does not change the volume of traffic using the bridge or approach. A supplemental traffic analysis conducted for the revised design confirms no significant change in traffic operational impacts (Fehr and Peers 2022). Therefore, the revised project would not worsen GHG emissions associated with project operation and the impact would remain less than significant.

Applicable Mitigation Measures Adopted for 2019 Certified FEIR None

Discussion
The 2019 Certified FEIR described the potential for accidental release of hazardous materials during construction activities. Construction activities uses heavy equipment, involving small quantities of hazardous materials (e.g., petroleum and other chemicals used to operate and maintain construction equipment) that may result in hazardous conditions in the project area. Construction of the modified project design would not change the severity of this potential impact.

The 2019 Certified FEIR described 12 sites with potentially hazardous material conditions located in or immediately adjacent to the project limits. Project construction in these areas could expose humans and the environmental to contaminated soil. Two of the known sites are within the limits of the proposed design modification and are associated with former development at the site of the current western Sacramento River levee (described in the 2019 Certified FEIR as Sites A and B). The recognized environmental conditions of these two sites are considered low. The design modifications do not increase the risk of exposing potentially hazardous material at a known site.

The 2019 Certified FEIR found that construction of the project could result in temporary and lessthan-significant disruptions to traffic flow where temporary lane shifts or closures are required, potentially affecting emergency vehicles, emergency response, or evacuation. Construction of the modified project design would not worsen the temporary traffic disruption.

Discussion
The 2019 Certified FEIR found that impacts on water quality and hydrology caused by project construction and operation would be less than significant. Construction-related activities would result in surface disturbances that have the potential to violate water quality standards or waste discharge requirements. Compliance with Waste Discharge Requirements that apply to the City of Sacramento (the Sacramento County municipal separate storm sewer systems (MS4) permit) (National Pollutant Discharge Elimination System No. CAS082597; Order No. R5-2015-0023) and the City of West Sacramento’s State Water Board's Phase II MS4 permit would ensure that impacts are less than significant. Construction of the modified project design would also comply with permits and regulations to meet water quality and waste discharge standards.

The project described in the 2019 Certified FEIR would increase the area of impervious surfaces in the vicinity of the project, increasing the amount of stormwater runoff. The 2019 Certified FEIR found that the design of roadway drainage included in the project and incorporation of the required Construction General Permit Stormwater Pollution Prevention Plan post-construction measures, site design measures, low impact development measures, and other permanent erosion control elements found in Caltrans’ MS4 program guidance documents, the Sacramento Stormwater Quality Partnership’s Stormwater Quality Improvement Program, and the City of West Sacramento’s Stormwater Management Program, would ensure that impacts related to stormwater runoff are less than significant. Any additional runoff created by the project will be routed into the existing stormwater drainage network, which the 2019 Certified FEIR documented has the available capacity. The reconfigured access to 2nd Street north of C Street requires a similar amount of new impervious surface and stormwater drainage collection and would not substantially increase stormwater runoff. Roadway drainage would still connect to the existing stormwater drainage network. Impacts would remain less than significant.

The design modifications do not change the project over the Sacramento River and would not affect drainage from the bridge itself, river flows, or water surface elevation.

Discussion
The 2019 Certified FEIR found that construction of the project would result in less-than-significant impacts related to changes in divisions already existing in the community or further dividing existing communities. The project maintains the community connectivity provided by the existing I Street Bridge and enhances the modes of travel across the river. However, the project described in the 2019 Certified FEIR would affect access to existing residential land uses on 2nd Street, north of C Street, requiring acquisition from seven individual parcels and removal of three structures to recreate the access after accommodating the new bridge infrastructure (2019 Certified FEIR:1-7).

Revisions to the project design reduce impacts by eliminating the need for housing relocations and acquisition of developed residential properties and maintaining access to properties on 2nd Street directly from C Street.

The 2019 Certified FEIR analyzed the consistency of the project with relevant local planning documents and policies and found the project consistent. The modified design for access to 2nd Street also is consistent with local policies but will require a revision to the depiction of the 2nd Street reconfiguration in the Washington Realized plan (City of West Sacramento 2015). The 2019 Certified FEIR describes a less-than-significant impact related to the Sacramento River Parkway Plan and the acquisition of approximately 1.246 acres of the Sacramento River Parkway. Revisions 396

to the project design in West Sacramento do not affect the Sacramento River Parkway and do not change the level of consistency with the Sacramento River Parkway Plan. Modifications to the project design do not change the overall project’s consistency with the goals and policies of the relevant local planning documents. The impact remains less than significant.

No land uses designated for mineral resource extraction and no mines of value to the region occur within or adjacent to the project limits. Revisions to the project design in West Sacramento are within the original project area analyzed in the 2019 Certified FEIR and do not change project impacts for this resource topic. 397

Discussion
The 2019 Certified FEIR describes significant project impacts from both temporary noise and groundborne vibration caused by the use of construction equipment, including pile drivers and vibratory rollers, and permanent increases in traffic noise above local standards.

The 2019 Certified FEIR summarizes typical noise levels associated with public works projects such as this project (see 2019 Certified FEIR Table 3-13). Because residential uses in West Sacramento are located within 50 to 100 feet of locations where construction activity will occur, the results in Table 3-13 indicate that construction noise would increase the ambient noise levels in the project vicinity and could exceed applicable City of West Sacramento standards for non-transportation sources, a significant impact. Table 3-16 in the 2019 Certified FEIR summarizes typical vibration level generated by construction equipment. The data in Table 3-16 indicate that pile driving and use of a vibratory roller could result in annoyance or potential damage to nearby structures, also a significant impact. After the application of the adopted mitigation measures listed in the 2019 Certified FEIR, the analysis concluded that temporary construction noise and groundborne vibration impacts could not feasibly be reduced to less-than-significant levels and were therefore unavoidable.

Revisions to the project design do not change the methods or equipment required to construct the project, nor do they reduce the distance between noise generating construction equipment and noise-sensitive land uses. Impacts are not expected to be worse than the project analyzed in the 2019 Certified FEIR however they remain significant and unavoidable.

The analysis of traffic noise conducted for the 2019 Certified FEIR used forecasted traffic data to model changes in noise from project traffic and found that noise impacts were predicted in interior spaces and at outdoor frequent human use areas in excess of standards established by West Sacramento (see 2019 Certified FEIR Table 3-5). Mitigation was adopted to reduce the significant impact to less-than-significant levels. A supplemental traffic analysis conducted for the revised design confirms no significant change in traffic operational impacts (Fehr and Peers 2022). The revised design does not change the volume of traffic using the bridge or approach roadways and does not locate traffic closer to existing land uses. Therefore, the revised project would not worsen the significant traffic noise impact described in the 2019 Certified FEIR. Mitigation adopted to reduce tire-pavement noise remains applicable to reduce traffic noise impacts to less-thansignificant levels.

The project is not located in the vicinity of a public or private airport or airstrip and would not change the exposure of people residing or working in the project area to noise levels related to airports. Revisions to the project design in West Sacramento do not change this impact conclusion.

Discussion
The 2019 Certified FEIR describes the potential for the project to cause growth-related impacts in the surrounding communities. The project entails replacing the existing I Street Bridge with a new bridge and would not increase roadway capacity. The land surrounding the project is developed or planned for development. The 2019 Certified FEIR found that while growth is expected in the surrounding region, it would not be attributable to, or otherwise influenced by, the project.

Revisions to the project design are minor and do not affect the less-than-significant growth impact conclusion for the project.

The project described in the 2019 Certified FEIR would require right-of-way acquisition from seven individual parcels and removal of three structures in West Sacramento: two individual residences (one on APN 010-101-010, and the other on APN 010-101-004), and apartment building that supports one individual apartment on APN 010-101-013 (2019 Certified FEIR:1-7). The number of people displaced was not considered substantial and no mitigation was necessary. Modifications to the project design would reduce residential impacts and eliminate the need to acquire residential property, a beneficial change in the project design.

Discussion
Multiple parks, trails, and open space areas are located throughout the project area, particularly along the Sacramento riverfront (2019 Certified FEIR Figure 2.1-4). The 2019 Certified FEIR found that the project would result in temporary and permanent impacts—including acquisition of land— on the riverfront parks in both the West Sacramento and Sacramento portions of the project area.

In West Sacramento, the project would result in the acquisition of approximately 0.135 acre from the southern portion of Broderick Boat Ramp. The area that would be acquired is at the southern portion of the park, away from the boat ramp itself and other developed facilities. The proposed River Walk Park area north of the existing I Street Bridge would also be affected; 3.083 acres would be acquired from this proposed park site (APNs 010-102-004, 010-102-003, 010-102-002, 010-102- 010, and 010-372-010). The parkland acquisitions required for the project would be minor and would not affect the overall viability of the parks and recreational facilities in the community. The impacts are considered less-than-significant.

A significant impact was identified in Sacramento due to the project’s effects on the Sacramento River Parkway Trail during construction. Mitigation to reduce the impact to a less-than-significant level was adopted by the City of Sacramento. The impact does not occur in West Sacramento.

Revisions to the project do not require additional acquisition of recreational land and do not change or worsen project impacts on recreational facilities.

Revisions to the project in West Sacramento and/or new circumstances relevant to the project would not, as compared to the 2019 Certified FEIR, result in new significant impacts relating to parks and other recreational facilities, or significant impacts that are substantially more severe than impacts previously disclosed. No new mitigation measures would be required. No new information or changes under the proposed project are known which would affect this conclusion. Therefore, the conclusions of the 2019 Certified FEIR remain valid, and no further analysis is required. 403

The 2019 Certified EIR identified project impacts on transit, bicycle, and pedestrian facilities as less than significant. Modifications to the project design in West Sacramento would shorten or maintain the travel distance from C Street to 2nd Street to the north for people walking or bicycling by adding a sidewalk connection from C Street east of 3rd Street to the new 2nd Street cul-de-sac and providing bicycle and pedestrian facility connections from the western bridge approach to the new 2nd Street access roadway. Revisions to the project do not affect transit operations. Impacts on transit, bicycle, and pedestrian facilities remain less than significant.

The 2019 Certified FEIR described significant impacts for unacceptable levels of service under opening year and cumulative year conditions at specific intersections in West Sacramento and Sacramento, and a location on Interstate 5, compared to thresholds adopted by West Sacramento, Sacramento and Caltrans. Impacts are listed in 2019 Certified FEIR Tables 3-7 to 3-11 and Table 3-

17. The implementation of the adopted mitigation measures listed in the 2019 Certified FEIR would reduce impacts to less-than-significant levels at all but one location. Conditions in the design year (2040) at the North 12th Street/North B Street intersection in Sacramento could not feasibly be reduced to less-than-significant levels and were therefore found to be unavoidable. Project design 404
City of West Sacramento Analysis and Findings
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 3-29 February 2023
modifications include reconfiguration of the lanes on the western bridge approach in West Sacramento to allow for left turns into and from the realigned 2nd Street and a westbound right turn taper into 2nd Street. Review of the modified design geometrics for changes in traffic circulation, queuing, and intersection operation (Fehr & Peers 2022) showed that the revised project would not affect the impact conclusions in the 2019 Certified FEIR. The recommendations included in the traffic analysis (longer westbound left-turn transition taper, and “Do Not Block” pavement markings at the new 2nd Street access) were incorporated into the revised design.

Subsequent to certification of the 2019 Certified FEIR, the State of California enacted amendments to CEQA and the Office of Planning and Research issued new CEQA Guidelines concerning the assessment of transportation impacts that generally recommend using vehicle miles traveled (VMT) and state that automobile delay does not constitute a significant impact under CEQA (PRC 21099 and 14 CCR 15064.3). While the 2019 Certified FEIR pre-dates the use of the newer approach to transportation impacts and does not discuss impacts related to changes in VMT under CEQA, it does present the results of modeled changes in VMT in Tables 2.5-11 and 2.5-16. The estimated regional VMT with and without the project are nearly the same. Table 2.5-16 shows that the project would reduce VMT by 2040 compared to conditions without the project. Modifications to the project design are for improved local access to a residential roadway and create a more direct route to 2nd Street as compared to the project described in the 2019 Certified FEIR. This change in the project reduces or has no effect on vehicle miles of travel.

The geometric design of the project must and would meet the standards of the City of West Sacramento, City of Sacramento, State of California, and U.S. Army Corps of Engineers—within each agency’s jurisdiction. Compliance with each respective standard would prevent geometric designrelated hazards and incompatible uses. The design modifications include creation of a residential inroad landscape island (traffic circle) that is a non-standard road design feature in West Sacramento.

The traffic circle will require final design review from City staff to ensure the design performs as required.

The 2019 Certified FEIR describes impacts related to changes in access and circulation during project construction and operation, including changing access to specific properties and routes for emergency responders. This impact was considered significant and mitigation measures were adopted that would reduce the impact to a less-than-significant level. Revisions to the project design north of C Street would be consistent with city standards and would allow fire department access and turn-around space for fire apparatus. In addition, the distance from the new cul-de-sac to the new terminus of 2nd Street would be approximately 150-feet, acceptable by fire department standards.

Would the project cause a
substantial adverse change in the
significance of a tribal cultural
resource, defined in PRC Section
21074 as either a site, feature,
place, cultural landscape that is
geographically defined in terms of
the size and scope of the landscape,
sacred place, or object with cultural
value to a California Native
American tribe, and that is:
a. Listed or eligible for listing in
the California Register of
Historical Resources, or in a
local register of historical
resources as defined in PRC
section 5020.1(k), or
N/A N/A No No N/A
b. A resource determined by the
lead agency, in its discretion
and supported by substantial
evidence, to be significant
pursuant to criteria set forth in
subdivision (c) of PRC Section
5024.1. 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.

N/A N/A No No N/A
Discussion
Assembly Bill (AB) 52 (Chapter 532, Statutes of 2014) established a formal consultation process for California Native American tribes as part of CEQA and equates significant impacts on tribal cultural resources with significant environmental impacts (PRC Section 21084.2). AB 52 became law on January 1, 2015, and only applies to projects that have a notice of preparation or notice of negative declaration/mitigated negative declaration filed on or after July 1, 2015. The notice of preparation for the project EIR was filed on September 22, 2014, prior to the effective date of AB 52. Tribal 406
City of West Sacramento Analysis and Findings
Addendum to the Environmental Impact Report for the
I Street Bridge Replacement Project 3-31 February 2023
consultation for the project did occur to support Section 106 of the National Historic Preservation Act, NEPA, and CEQA and is described in the 2019 Certified FEIR starting on page 2.7-5.

Applicable Mitigation Measures Adopted for 2019 Certified FEIR None
Conclusion
AB 52 requires that “prior to the release of a negative declaration, mitigated negative declaration, or environmental impact report for a project, the lead agency shall begin consultation” (PRC Section 21808.3.1[a]), and that “the lead agency may certify an environmental impact report or adopt a mitigated negative declaration for a project with a significant impact on an identified tribal cultural resource only if” consultation is formally concluded (PRC Section 21082.3[d]). However, this addendum for the project design modifications in West Sacramento is to the 2019 Certified EIR in accordance with 14 CCR 15164. An addendum was determined to be the most appropriate document because none of the conditions described in Section 15162, calling for preparation of a subsequent EIR, have occurred. The addendum addresses minor technical changes to the project and confirms that the modified project design is consistent with what was previously analyzed under the 2019 Certified FEIR. Therefore, the AB 52 procedures specified in PRC Sections 21080.3. 1(d) and 21080.3.2 do not apply and no tribal consultation under AB 52 is required.

Discussion
The 2019 Certified FEIR documented that the project would not affect most utility and service system resources. The project described in the 2019 Certified FEIR would increase the amount of impervious surface area in the vicinity of the project, increasing the amount of stormwater runoff but not requiring expansion of existing stormwater drainage facilities or construction of new facilities outside the project footprint. The 2019 Certified FEIR found this impact less than significant. Revisions to the project design in West Sacramento are within the original project limits analyzed in the 2019 Certified FEIR and do not change the project’s need for power facilities, waters supply, water treatment, or solid waste facilities. The reconfigured access to 2nd Street north of C Street requires a similar amount of new impervious surface and stormwater drainage collection and would not substantially increase stormwater runoff. The impact would remain less than significant.

Applicable Mitigation Measures Adopted for 2019 Certified FEIR None
Conclusion
Revisions to the project in West Sacramento and/or new circumstances relevant to the project would not, as compared to the 2019 Certified FEIR, result in new significant impacts relating to utilities and service systems, or significant impacts that are substantially more severe than impacts 408

wildfire or the uncontrolled
spread of a wildfire?

c. Require the installation or
maintenance of associated

fuel breaks, emergency water
sources, power lines, or other
utilities) that may exacerbate
fire risk or that may result in
temporary or ongoing impacts
on the environment?
N/A N/A No No N/A
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?
N/A N/A No No N/A
Discussion
Impacts of the project related to fire hazard severity zones were not evaluated in the 2019 Certified FEIR because at that time wildfire was not a separate topic area evaluated on the CEQA Checklist.

The project is not in or near a state responsibility area or lands classified as a very high fire hazard severity zone. Revisions to the project design in West Sacramento do not change the project location.

There would be no impact. Emergency evacuation and response is addressed under Hazard and Hazardous Materials, above.

Chapter 4
Conclusion
Based on the review of the proposed design modifications to the previously-approved prior project, evaluated above, and on the basis of the whole record, there is substantial evidence to support the determination that the 2019 Certified FEIR remains relevant in considering the environmental impacts of the project changes and there is no substantial evidence to support a fair argument that the changes to the project, as identified in this addendum, may have a significant effect on the environment beyond that which was evaluated in the 2019 Certified FEIR. A Subsequent EIR or MND is not required pursuant to the California Environmental Quality Act of 1970 (Sections 21000, et. seq., PRC of the State of California). CEQA Guidelines in 14 CCR 15164(a) states the following:

The lead agency or a responsible agency shall prepare an addendum to a previously Certified FEIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a Subsequent EIR have occurred.

The project design modifications in West Sacramento would not result in new significant environmental effects or a substantial increase in the severity of previously identified significant effects due to substantial project changes or a substantial change in circumstances beyond those evaluated in the 2019 Certified FEIR. Furthermore, new information does not indicate that the modified design would have one or more significant effects not discussed in the 2019 Certified FEIR; that significant effects previously examined would be substantially more severe than shown in the 2019 Certified FEIR; that mitigation measures or alternatives previously found not to be feasible would in fact be feasible; or that mitigation measures or alternatives which are considerably different from those analyzed in the 2019 Certified FEIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measures or alternative. Therefore, an addendum was prepared to comply with CEQA. 411

Mitigated Negative Declaration
I Street Bridge Deck Conversion
for Active Transportation
Project Description
The I Street Bridge Deck Conversion for Active Transportation Project would maintain and improve active transportation use on the upper deck of the existing I Street Bridge. As a part of the separate I Street Bridge Replacement Project, the existing roadway approach ramps to the I Street Bridge from I Street and Jibboom Street in Sacramento and from C Street in West Sacramento would be removed. The proposed deck conversion project would retain a portion of each approach ramp structure on each end of the existing I Street Bridge to accommodate access points for pedestrians and bicyclists. The retained portions would be used as raised platforms to which Americans with Disabilities Act (ADA)-compliant pedestrian ramps would be attached. These platforms already span over the active railroad tracks.

Four ADA-compliant bicycle/pedestrian ramps would be constructed, two in West Sacramento and two in Sacramento. In West Sacramento, one ramp would be constructed north of the existing I Street Bridge, and the other to south of the existing bridge. In Sacramento, one ramp would be constructed north of the existing bridge, the other would be to the south and would be designed to accommodate maintenance vehicles to allow Union Pacific Railroad (UPRR) to access the bridge for their routine maintenance activities and to provide City maintenance or emergency vehicle access, when required. The new ramps would provide user connectivity to existing pathways and travel routes for bicyclists and pedestrians (commuting and recreational use). Stairways may be incorporated into one ramp on each side.

Project Location
The project is located at the I Street Bridge (Bridge No. 22C0153), specifically the upper deck of the bridge, and the areas immediately adjacent to the bridge in both West Sacramento and Sacramento.

The I Street Bridge currently serves as an important link between West Sacramento’s historic Washington District, CalSTRS and The Ziggurat buildings, and Sacramento’s Sacramento Valley Station, Old Sacramento, and central city.

Potential Impacts
The proposed project would result in no impact on agricultural and forestry resources, geology and soils, land use and planning, mineral resources, population and housing, public services, and recreation.

The proposed project would have less than significant impacts on energy, greenhouse gas emissions, hydrology and water quality, noise, and transportation.

Although the proposed project could result in significant impacts on aesthetics, air quality, biological resources, cultural resources, paleontology, hazards and hazardous materials, and tribal cultural 418
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-2
January 2023
ICF 104242
resources, these impacts would be reduced to less-than-significant levels with the incorporation of the following mitigation measures.

Mitigation Measure AIR-1: Implement Additional Control Measures for Construction Emissions of Fugitive Dust
Additional measures to control dust in Yolo County will be borrowed from YSAQMD’s recommended list of dust control measures and implemented to the extent practicable when the measures have not already been included in and do not conflict with the requirements or other permits and authorizations issued for the project. The following measures are taken from YSAQMD’s Construction Dust Mitigation Measures (Yolo-Solano Air Quality Management District 2007).
 Water all active construction sites at least twice daily. Frequency should be based on the type of operation, soil, and wind exposure.
 Haul trucks shall maintain at least 2 feet of freeboard.  Cover all trucks hauling dirt, sand, or loose materials.  Apply non-toxic binders (e.g., latex acrylic copolymer) to exposed areas after cut-and-fill operations and hydroseed area.
 Apply chemical soil stabilizers on inactive construction areas (disturbed lands within construction projects that are unused for at least 4 consecutive days).  Plant tree windbreaks on the windward perimeter of construction projects if adjacent to open land.
 Plant vegetative ground cover in disturbed areas as soon as possible.  Cover inactive storage piles.
 Sweep streets if visible soil material is carried out from the construction site.  Treat accesses to a distance of 100 feet from the paved road with a 6- to 12-inch layer of wood chips or mulch.
 Treat accesses to a distance of 100 feet from the paved road with a 6-inch layer of gravel.

Additional measures to control dust in Sacramento County will be borrowed from SMAQMD’s recommended list of dust control measures and implemented to the extent practicable when the measures have not already been included in, and do not conflict with, the requirements of other permits and authorizations issued for the project. The following measures are taken from SMAQMD’s (2021) Guide to Air Quality Assessment in Sacramento County and represent their basic control measures for fugitive dust.
 Water all exposed surfaces two times daily. Exposed surfaces include, but are not limited to soil piles, graded areas, unpaved parking areas, staging areas, and access roads.  Cover or maintain at least 2 feet of free board space on haul trucks transporting soil, sand, or other loose material on the site. Any haul trucks that would be traveling along freeways or major roadways should be covered.
 Use wet power vacuum street sweepers to remove any visible track out mud or dirt onto adjacent public roads at least once a day. Use of dry power sweeping is prohibited. 419
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-3
January 2023
ICF 104242
 Limit vehicle speeds on unpaved roads to 15 mph.
 All roadways, driveways, sidewalks, and parking lots to be paved should be completed as soon as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.

Mitigation Measure BIO-1: Install Orange Construction Fencing between the Construction Area and Adjacent Sensitive Biological Resources
The project proponent and/or its contractor will install orange construction fencing between the construction area and adjacent sensitive biological resource areas. Sensitive biological resources that occur adjacent to the construction area that could be directly affected by the project include natural communities of special concern; special-status wildlife habitats for valley elderberry longhorn beetle; nest sites of Swainson’s hawk, purple martin, or other migratory birds; roosting bats; and protected trees to be avoided. Barrier fencing around sensitive areas will be installed as one of the first orders of work and prior to equipment staging. Before construction begins, the construction contractor will work with the project engineer and a resource specialist to identify the locations for the orange construction fencing and will place stakes around the sensitive resource sites to indicate these locations. Where buffers prescribed by the Yolo HCP/NCCP are not feasible, such as a 100-foot buffer from riparian canopy drip line, buffers appropriate for this active transportation project that connects to an existing bridge crossing will be used as long as they are consistent with the other project mitigation measures (e.g. species-specific non-disturbance buffers) adopted to avoid significant impacts. The protected areas will be designated as environmentally sensitive areas and clearly identified on the construction plans and described in the specifications. To minimize the potential for snakes and other ground-dwelling animals from being caught in the orange construction fencing, the fencing will be placed with at least a 1-foot gap between the ground and the bottom of the orange construction fencing. The exception to this condition is where construction barrier fencing overlaps with erosion control fencing and must be secured to prevent sediment runoff.

Barrier fencing will be installed before construction activities are initiated, maintained throughout the construction period, and removed after completion of construction.

Mitigation Measure BIO-2: Conduct Environmental Awareness Training for Construction Employees
The project proponent will retain a qualified biologist to conduct environmental awareness training for construction crews before project implementation. The awareness training will be provided to all construction personnel and will brief them on the need to avoid effects on sensitive biological resources (e.g., native trees, riparian habitat, and special-status species habitats in and adjacent to the construction area). The education program will include a brief review of the special-status species with the potential to occur in the project area (including their life history, habitat requirements, and photographs of the species). The training will identify the portions of the project area in which the species may occur, as well as their legal status and protection. The program also will cover the restrictions and guidelines that must be followed by all construction personnel to reduce or avoid effects on these species during project implementation. This will include the steps to be taken if a sensitive species is found within the construction area (i.e., notifying the crew foreman, who will call a designated biologist). In addition, construction employees will be educated about the importance of controlling and preventing the spread of invasive plant infestations. An environmental awareness handout that 420
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-4
January 2023
ICF 104242
describes and illustrates sensitive resources to be avoided during project construction and identifies all relevant permit conditions will be provided to each crew member. The crew foreman will be responsible for ensuring that crew members adhere to the guidelines and restrictions. Education programs will be conducted for appropriate new personnel as they are brought on the job during the construction period.

Mitigation Measure BIO-3: Conduct Periodic Biological Monitoring The project proponent will retain a qualified biological monitor for the project who will visit the site a minimum of once per month to ensure that fencing around environmentally sensitive areas is intact and that activities are being conducted in accordance with the agreed upon project schedule and agency conditions of approval. The monitor will provide the project proponent with a monitoring log for each site visit. Certain activities will require a biological monitor to be present for the duration of the activity or during the initial disturbance of an area to ensure that impacts on special-status species are avoided.

Mitigation Measure BIO-4: Conduct Preconstruction Surveys for Crotch Bumble Bee and Western Bumble Bee and Avoid Active Nests
Pre-construction surveys for active bee nest colonies and associated floral resources (i.e., flowering vegetation on which bees from the colony are observed foraging) no more than 30 days prior to any ground disturbance between March and September. The purpose of this preconstruction survey would be to identify active nest colonies and associated floral resources in impact areas that could be avoided by construction personnel. The project biologist would establish, monitor, and maintain no-work buffers around nest colonies and floral resources identified during surveys. The size and configuration of the no-work buffer would be based on best professional judgment of the project biologist. At a minimum, the buffer would provide at least 20 feet of clearance around nest entrances and maintain disturbance-free airspace between the nest and nearby floral resources. Construction activities would not occur within the no-work buffers until the colony is no longer active (i.e., no bees are seen flying in or out of the nest for three consecutive days indicating the colony has completed its nesting season and the next season’s queens have dispersed from the colony).

Mitigation Measure BIO-5: Protect Crotch Bumble Bee and Western Bumble Bee Food Plants from Herbicide and Pesticide Use
To minimize impacts on Crotch bumble bee and western bumble bee from pesticide and herbicide drift, application of these chemicals will be limited to the extent feasible and will be conducted using handheld equipment. Herbicides and pesticides will be applied only by applicators with current licenses and/or certifications from the California Department of Pesticide Regulation. The applicator will follow the pesticide and herbicide label directions.

Spray nozzles will be kept within 24 inches of target areas during spraying. The most current information on pesticide and herbicide toxicity on wildlife will be used to inform future decisions about their use during project operation.

Mitigation Measure BIO-6: Revegetate Temporary Impact Areas within Crotch Bumble Bee and Western Bumble Bee Habitat
The project proponent will include suitable native nectar- and pollen-producing plants commonly used as food sources by Crotch bumble bee and western bumble bees in on-site 421
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-5
January 2023
ICF 104242
revegetation and erosion control plans. Native plants of the following genera are appropriate for Crotch bumble bee: Antirrhinum, Asclepias, Phacelia, Chaenactis, Clarkia, Dendromecon, Eriogonum, Eschscholzia, Lupinus, Medicago, and Salvia. Native plants of the following taxa are appropriate for western bumble bee: Asteraceae, Ceanothus, Centaurea, Chrysothamnus, Cirsium, Eriogonum, Geranium, Grindelia, Lupinus, Melilotus, Monardella, Rubus, Penstemon, Solidago, and Trifolium.

Mitigation Measure BIO-7: Conduct Preconstruction Surveys for Western Pond Turtle and Allow Turtles to Leave Work Area Unharmed
To avoid potential injury to or mortality of western pond turtles, the project proponent will retain a qualified biologist to conduct a preconstruction survey for western pond turtles immediately prior to construction activities (including vegetation removal) along the banks of the Sacramento River. The biologist will survey riparian and ruderal habitat within the construction area immediately prior to disturbance if a western pond turtle is found within the immediate work area during the preconstruction survey or during project activities, work will cease in the area until the turtle is able to move out of the work area on its own. Information about the location of turtles seen during the preconstruction survey will be included in the environmental awareness training (Mitigation Measure BIO-2, Conduct Environmental Awareness Training for Construction Employees) and provided directly to the construction crew working in that area to ensure that areas where turtles were observed are inspected each day prior to the start of work to ensure that no turtles are present. Workers will cover open trenches and holes associated with construction activities or design the trenches and holes with escape ramps that can be used during non-working hours. The contractor will inspect open trenches and holes prior to filling and contact a qualified biologist to remove or release any trapped wildlife found in the trenches or holes. If a western pond turtle nest is discovered during the preconstruction survey or during project construction, the project proponent will coordinate with CDFW to determine whether additional avoidance measures (e.g., no-disturbance buffer or monitoring) is prudent.

Mitigation Measure BIO-8: Conduct Preconstruction Surveys for Nesting Migratory Birds, Including Special-Status Birds, and Establish Protective Buffers The project proponent will retain a qualified wildlife biologist to conduct nesting surveys before the start of construction. These nesting surveys will be conducted in conjunction with the Swainson’s hawk and white-tailed kite nesting surveys (see Mitigation Measure BIO-10, Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction) and will include a minimum of three separate surveys to look for active nests of migratory birds, including raptors. Surveys will include a search of all structures, trees, shrubs, ruderal areas, and grassland vegetation that provide suitable nesting habitat within a 0.25-mile (raptors) and a 500-foot (non-raptors) radius around disturbance areas. Surveys should occur during the height of the breeding season (March 1 to June 1), with one survey occurring in each of the 2 consecutive months within this peak period and the final survey occurring within 1 week of the start of construction. If no active nests are detected during these surveys, no additional measures are required. If an active nest is found in the survey area, a no-disturbance buffer will be established to avoid disturbance or destruction of the nest site until the end of the breeding season (September 15) or until after a qualified wildlife biologist determines that the young have fledged and moved out of the construction area (this date varies by species). The extent of 422
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-6
January 2023
ICF 104242
these buffers will be determined by the biologist in coordination with CDFW and will depend on the level of noise or construction disturbance taking place, line-of-sight between the nest and the disturbance, ambient levels of noise and other non-project disturbances, and other topographical or artificial barriers. Suitable buffer distances may vary between species. Fish and Game Code protections for nesting and migratory birds apply regardless of the time of year, and some bird species may nest during the winter and fall months. If an active nest is discovered outside of the typical nesting season, it will be avoided using the same avoidance measures that would be applied during the typical nesting season until such time a qualified wildlife biologist determines that the young have fledged.

Mitigation Measure BIO-9: Conduct Tree Removal during Non-Sensitive Periods for Wildlife
The project proponent will remove or trim trees during the non-breeding season for treenesting migratory birds and raptors, and prior to periods when bats would be hibernating (generally between September 15 and October 31). If tree removal cannot be confined to this period, the project proponent will retain a qualified wildlife biologist with knowledge of the wildlife species that could occur in the project area to conduct the appropriate preconstruction surveys and establish no-disturbance buffers for sensitive wildlife species as described under mitigation measures for Swainson’s hawk and white-tailed kite, nesting birds, and roosting bats (see Mitigation Measures BIO-8 and BIO-10 through BIO-13). Implementation of the following measures will avoid and minimize impacts on purple martins, as well as other nesting birds and bats that use the approach structures.

Mitigation Measure BIO-10: Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction
The project proponent will retain a wildlife biologist experienced in surveying for Swainson’s hawk and white-tailed kite to conduct surveys for these species in the spring/summer prior to construction. The surveys will be conducted within the limits of disturbance and in a buffer area up to 0.25 mile from the limits of disturbance. The size of the buffer area surveyed will be based on the type of habitat present and the line-of-sight from the construction area to surrounding suitable breeding habitat. Surveys will follow the methods in Recommended Timing and Methodology for Swainson’s Hawk Nesting Surveys in California’s Central Valley (Swainson’s Hawk Technical Advisory Committee 2000). A minimum of six surveys will be conducted according to these methods. If a variance of the survey distance or number of surveys is necessary, the project proponent will coordinate with CDFW regarding appropriate survey methods based on proposed construction activities. Surveys generally will be conducted from February to July. Survey methods and results will be reported to the project proponent and CDFW.

Mitigation Measure BIO-11: Monitor Active Swainson’s Hawk and White-Tailed Kite Nests during Construction Activities
The proposed project is in an urban area subject to noise and disturbance from vehicle and pedestrian traffic on the existing I Street Bridge and surface streets, and from boat traffic along the Sacramento River; therefore, if Swainson’s hawk or white-tailed kite are present in the project area, they are already exposed to a relatively high level of disturbance under existing conditions. Although the monitoring and non-disturbance buffers prescribed by the Yolo 423
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-7
January 2023
ICF 104242
HCP/NCCP are 1,320 feet, because of the existing noise and disturbance in the project area, the monitoring and non-disturbance buffers of 600 feet under the proposed project would be sufficient to avoid take and adverse effects, consistent with the intent of Yolo HCP/NCCP AMM 16, Minimize Take and Adverse Effects on Habitat of Swainson’s Hawk and White-Tailed Kite.

Active Swainson’s hawk and white-tailed kite nests within 600 feet of the study area will be monitored during construction. Monitoring will be conducted by a wildlife biologist with experience in monitoring Swainson’s hawk and white-tailed kite nests. The monitor will document the location of active nests, coordinate with the project proponent and CDFW, and record all observations in a daily monitoring log. The monitor will have the authority to temporarily stop work if activities are disrupting nesting behavior to the point of resulting in potential take (i.e., eggs and young chicks are still in the nest, and adults appear agitated and could potentially abandon the nest). The monitor will work closely with the contractor, the project proponent, and CDFW to develop plans for minimizing disturbance, such as modifying or delaying certain construction activities.

A minimum non-disturbance buffer of 600 feet (radius) will be established around all active Swainson’s hawk and white-tailed kite nests. No entry of any kind related to construction will be allowed within this buffer while the nest is active, unless approved by CDFW through issuance of an incidental take permit or through consultation during project construction. The buffer size may be modified based on site-specific conditions, including line-of-sight, topography, type of disturbance, existing ambient noise and disturbance levels, and other relevant factors. Entry into the buffer for construction activities will be granted when the biological monitor determines that the young have fledged and are capable of independent survival, or that the nest has failed and the nest site is no longer active. All buffer adjustments will be approved by CDFW.

Mitigation Measure BIO-12: Avoid and Minimize Impacts on Purple Martins during Construction Activities
No construction activity that results in ground disturbance, loud noises, and/or vibrations will be conducted within 100 feet of the edge of the purple martin colony during the purple martin nesting season (March 15 to August 15). In addition, no construction-related vehicles or machinery shall be operated or stored beneath the colony during this period or until a qualified biologist determines that the purple martins have completed nesting and are no longer occupying the structure.

Mitigation Measure BIO-13: Conduct Preconstruction Surveys for Tree Roosting Bats and Implement Protective Measures
To avoid and minimize potential impacts on pallid bat, western red bat, and non-special-status bat species from the removal of trees and construction noise and vibration, the project proponent will implement the following actions.

Preconstruction Surveys
One month prior to tree trimming or removal, a qualified biologist will examine trees to be removed or trimmed and trees or structures within the vicinity of construction activities (a minimum of 100 feet) for suitable bat roosting habitat. High-quality habitat features (e.g., crevices, large tree cavities, basal hollows, loose or peeling bark, larger snags) will be identified, and the area around these features searched for bats and bat sign (e.g., guano, culled insect 424
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-8
January 2023
ICF 104242
parts, staining). Riparian woodland and stands of mature broadleaf trees will be considered potential habitat for solitary foliage-roosting bat species.

If suitable roosting habitat and/or bat sign is detected, biologists will conduct an evening visual emergence survey of the source habitat feature, from a half hour before sunset to 1–2 hours after sunset for a minimum of 2 nights. Full-spectrum acoustic detectors will be used during emergence surveys to assist in species identification. If site security allows, detectors should be set to record bat calls for the duration of each night. All emergence and monitoring surveys will be conducted during favorable weather conditions (calm nights with temperatures conducive to bat activity and no precipitation predicted). The biologist will analyze the bat call data using appropriate software and prepare a report that will be submitted to the project proponent and CDFW.

Protective Measures
Protective measures may be necessary if it is determined that bats are using trees in the study area as roost sites, or if sensitive bats species are detected during acoustic monitoring. The following measures will be implemented when roosts are found within trees planned for removal according to the timing discussed above. Specific measures will be approved by the project proponent and CDFW prior to excluding bats from occupied roosts.  Trees planned for removal will have exclusion devices installed between September 15 and October 31 to avoid affecting maternal and hibernating bat roosts. The exact timing of removal and demolition will be determined based on preconstruction surveys of trees.  Exclusion from roosts will take place late in the day or in the evening to reduce the likelihood of evicted bats falling prey to diurnal predators and will take place during weather and temperature conditions conducive to bat activity.  Biologists experienced with bats and bat evictions will carry out or oversee the exclusion tasks and will monitor tree trimming and removal.
 Trees that provide suitable roost habitat will be removed in pieces, rather than felling the entire tree and should be done late in the day or in the evening to reduce the likelihood of evicted bats falling prey to diurnal predators and will take place during warm weather conditions conducive to bat activity.
 Structural changes may be made to a known roost proposed for removal, to create conditions in the roost that are undesirable to roosting bats and encourage the bats to leave on their own (e.g., open additional portals so that temperature, wind, light and precipitation regime in the roost change).
 Structural changes to the roost will be authorized by CDFW and will be performed during the appropriate exclusion timing (listed above) to avoid harming bats.  Non-injurious harassment at the roost site, such as ultrasound deterrents or other sensory irritants, may be used to encourage bats to leave on their own.  One-way door devices will be used where appropriate to allow bats to leave the roost but not to return.
 Prior to tree removal/trimming and after other eviction efforts have been attempted, any confirmed roost site will be gently shaken or repeatedly struck with a heavy implement such as a sledgehammer or an axe. Several minutes should pass before felling trees or trimming 425

ICF 104242
limbs to allow bats time to arouse and leave the roost. A biological monitor will search downed vegetation for dead and injured bats. The presence of dead or injured bats will be reported to CDFW. Injured bats will be transported to the nearest CDFW-permitted wildlife rehabilitation facility.
 No construction activity that results in ground disturbance, loud noises, and/or vibrations will be conducted within 100 feet of the edge of occupied roosts during the maternity season (April 1 to September 15). In addition, no construction-related vehicles or machinery shall be operated or stored beneath the colony during this period or until a qualified biologist determines that the purple martins have completed nesting and are no longer occupying the structure.
 Biologists experienced with bats will monitor construction activities within 100 feet of identified roosts to ensure that roosting bats are not disturbed.

Mitigation Measure BIO-14: Avoid the Introduction and Spread of Invasive Plants The project proponent or its contractor will be responsible for avoiding the introduction of new invasive plants and the spread of invasive plants previously documented in the project’s study area. The following measures will be implemented during and after construction.  Educate construction supervisors and managers on weed identification and the importance of controlling and preventing the spread of invasive weeds.  Dispose of invasive species material removed during project construction offsite at an appropriate disposal facility to avoid the spread of invasive plants into natural areas.  Minimize surface disturbance to the greatest extent feasible to complete the work.  Restore to pre-project conditions all temporarily disturbed areas, including project staging areas, within one year of completion of project construction.  Use weed-free imported erosion-control materials (or rice straw in upland areas).  Use locally grown native plant stock and native or naturalized (noninvasive) grass seed during revegetation.
 If feasible, remove black locust trees from the riparian forest in and adjacent to the impact area on the Sacramento side of the bridge and any red sesbania trees in or adjacent to the impact area on the West Sacramento side.

Mitigation Measure BIO-15: Compensate for Loss of Protected Trees Within 1 year prior to construction, the project proponent will conduct a preconstruction inventory of all protected trees to be removed within the project area. The inventory will include the location, species, diameter of all trunks, approximate height and canopy diameter, and approximate age, in support of a tree permit for removal of the protected trees. All conditions of the tree permit will be implemented.

The project proponent will mitigate for the loss of protected trees using one or a combination of the two following options.
 If feasible, plant replacement trees at or near the location of the tree removal. Replacement trees will be required at a ratio of 1:1 (i.e., 1-inch diameter of replacement tree planted for 426
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-10
January 2023
ICF 104242
every 1-inch diameter of tree removed). Replacement trees will be of the same species.

Mitigation will be subject to approval by the City’s tree administrator and will take into account species affected, replacement species, location, health and vigor, habitat value, and other factors to determine fair compensation for tree loss. Replacement trees will be monitored annually for 3 years to document vigor and survival. If any of the replacement trees die within 3 years of the initial planting, the project proponent will plant additional replacement trees and monitor them until all trees survive for a minimum of 3 years after planting.
 If adequate space is not available in the project area for tree planting after construction, pay an in-lieu fee to the City of West Sacramento, which would be used to purchase and plant trees elsewhere in West Sacramento, following the same replacement ratio, species, monitoring, and tree survival requirements described for the option above.

Mitigation Measure CUL-1: Implement Measures to Protect Previously Unidentified Cultural Resources
 Construction shall stop if potential cultural resources are encountered. It is possible that previous activities have obscured surface evidence of cultural resources. If signs of an archeological site, such as any unusual amounts of stone, bone, or shell, are uncovered during grading or other construction activities, work will be halted within 100 feet of the find and the City of West Sacramento will be notified. A qualified archeologist will be consulted for an onsite evaluation. If the site appears to be eligible for listing in state or federal registers, additional mitigation, such as further testing for evaluation or data recovery, may be necessary.
 In the event resources are discovered, the City of West Sacramento will retain a qualified archaeologist to assess the find and to determine whether the resource requires further study. Any previously undiscovered resources found during construction will be recorded on appropriate California Department of Parks and Recreation 523 forms and evaluated for significance under all applicable regulatory criteria.
 All work will stop in the immediate vicinity of the find, and, if the find is determined to be an important cultural resource, the City of West Sacramento will make available contingency funding and a time allotment sufficient to allow recovery of an archaeological sample or to implement an avoidance measure. Construction work may continue on other parts of the project while archaeological mitigation takes place.

Mitigation Measure CUL-2: Implement Measures if Construction Activities Inadvertently Discover or Disturb Human Remains
 If human remains are discovered during any phase of construction, including disarticulated or cremated remains, the construction contractor will immediately cease all grounddisturbing activities within 100 feet of the remains and notify the City of West Sacramento.  In accordance with California State Health and Safety Code Section 7050.5, no further disturbance will occur until the following steps have been completed.  The County Coroner has made the necessary findings as to origin and disposition pursuant to Public Resources Code Section 5097.98.
427
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-11
January 2023
ICF 104242
 If the remains are determined by the County Coroner to be Native American, NAHC will be notified within 24 hours, and the treatment and disposition of the remains will comply with NAHC guidelines.
 It is further recommended that a professional archaeologist with Native American burial experience conduct a field investigation of the specific site and consult with the Most Likely Descendant (MLD), if any, identified by NAHC. As necessary and appropriate, a professional archaeologist may provide technical assistance to the MLD, including excavation and removal of the human remains.

Mitigation Measure GEO-1: Stop Work if Substantial Fossil Remains are Encountered during Construction
If substantial fossil remains (particularly vertebrate remains) are discovered during earth disturbing activities, activities will stop immediately until a qualified professional paleontologist can assess the nature and importance of the find and can recommend appropriate treatment.

Treatment may include preparation and recovery of fossil materials so that they can be housed in an appropriate museum or university collection and may also include preparation of a report for publication describing the finds. The project proponent will be responsible for ensuring that recommendations regarding treatment and reporting are implemented.

Minimization Measure GHG-1: Implement SMAQMD’s Recommended Construction GHG BMPs
The project proponent will implement the following SMAQMD’s recommended GHG reduction measures, to the extent feasible.
 Improve fuel efficiency from construction equipment.
 Minimize idling time either by shutting equipment off when not in use or reducing the time of idling to no more than 3 minutes (5-minute limit is required by the state airborne toxics control measure [Title 13, Sections 2449(d)(3) and 2485 of the California Code of Regulations]). Provide clear signage that posts this requirement for workers at the entrances to the site.
 Maintain all construction equipment in proper working condition according to manufacturer’s specifications. The equipment must be checked by a certified mechanic and determined to be running in proper condition before it is operated.  Train equipment operators in proper use of equipment.  Use the proper size of equipment for the job.
 Use equipment with new technologies (repowered engines, electric drive trains).  Perform onsite material hauling with trucks equipped with on-road engines (if determined to be less emissive than the off-road engines).
 Use alternative fuels for generators at construction sites, such as propane or solar, or use electrical power.
 Use a CARB-approved low carbon fuel for construction equipment. (NOx emissions from the use of low carbon fuel must be reviewed and increases mitigated.) 428
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-12
January 2023
ICF 104242
 Encourage and provide carpools, shuttle vans, transit passes and/or secure bicycle parking for construction worker commutes.
 Reduce electricity use in the construction office by using compact fluorescent bulbs, powering off computers every day, and replacing heating and cooling units with more efficient ones.
 Recycle or salvage non-hazardous construction and demolition debris (goal of at least 75 percent by weight).
 Use locally sourced or recycled materials for construction materials (goal of at least 20 percent based on costs for building materials, and based on volume for roadway, parking lot, sidewalk and curb materials). Wood products utilized should be certified through a sustainable forestry program.
 Minimize the amount of concrete for paved surfaces or utilize a low-carbon concrete option.  Produce concrete on-site if determined to be less emissive than transporting ready mix.  Use SmartWay certified trucks for deliveries and equipment transport.  Develop a plan to efficiently use water for adequate dust control.

Mitigation Measure HAZ-1: Develop and Implement a Health and Safety Plan The project proponent will develop and implement a health and safety plan to address worker safety when working with potentially hazardous materials, including potential ADL, TPHs, PCBs, and other construction-related materials within the ROW during any soil-disturbing activity.

The plan will include identification of appropriate fueling and maintenance areas for equipment, daily equipment inspection schedule, a spill response plan, spill response supplies to be maintained on site, and a complete list of the agencies to be notified (with their telephone numbers).

Mitigation Measure HAZ-2: Perform Soil Testing and Appropriately Dispose of Soils Contaminated with ADL
The project proponent will conduct soil testing for ADL contamination in the project area along C Street, 2nd Street, and at the bridge approach/viaduct leading from C Street in West Sacramento, and within the proposed project limits in Sacramento at the bridge approach leading from I Street. If soils contain ADL in excess of established thresholds, soils will be handled in a manner compliant with the County Certified Unified Program Agency regulatory requirements and disposed of properly. The testing may be conducted in conjunction with testing required for the separate I Street Bridge Replacement Project.

Mitigation Measure HAZ-3: Perform a Phase II Environmental Site Assessment Prior to Construction Activities and Remediate if Necessary
Prior to construction, the project proponent will conduct a Phase II environmental site assessment in conformance with the American Society for Testing and Materials Standard Practice E1527-05. All environmental investigation, sampling, and remediation activities associated with the project will be conducted under a work plan approved by the regulatory oversight agency and will be conducted by the appropriate environmental professional consistent with Phase II environmental site assessment requirements. The environmental site 429
I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration MND-13
January 2023
ICF 104242
assessment may occur in conjunction with the Phase II assessment conducted for the separate I Street Bridge Replacement Project.

The Phase II environmental assessment will include sampling and laboratory analysis to confirm the presence of hazardous materials and may include the following.  Collection of original surface and/or subsurface samples of soil, groundwater to analyze for quantities of various contaminants.
 Subsurface soil borings.
 An analysis to determine the vertical and horizontal extent of contamination (if the evidence from sampling shows contamination).

If contamination is uncovered as part of Phase II environmental site assessment, remediation will be required. Any contaminated soil identified on a project site must be properly disposed of in accordance with DTSC regulations in effect at the time.

If, during construction, soil or groundwater contamination is suspected, construction activities will cease and appropriate health and safety procedures will be implemented, including the use of appropriate personal protective equipment (e.g., respiratory protection, protective clothing, helmets, goggles).

Mitigation Measure TCR-1: Implement Measures to Protect Previously Unidentified Tribal Cultural Resources
If any suspected tribal cultural resources are discovered during ground disturbing construction activities, all work shall cease within 100 feet of the find, or an agreed upon distance based on the project area and nature of the find. A Tribal Representative from a California Native American tribe that is traditionally and culturally affiliated with a geographic area shall be immediately notified and shall determine if the find is a tribal cultural resource (Pub. Resources Code Section 21074). The Tribal Representative will make recommendations for further evaluation and treatment as necessary.

When avoidance is infeasible, preservation in place is the preferred option for mitigation of tribal cultural resources under CEQA, and every effort shall be made to preserve the resources in place, including through project redesign, if feasible. Culturally appropriate treatment may be, but is not limited to, processing materials for reburial, minimizing handling of cultural objects, leaving objects in place within the landscape, or returning objects to a location within the project area where they will not be subject to future impacts. Permanent curation of tribal cultural resources will not take place unless approved in writing by the California Native American tribe that is traditionally and culturally affiliated with the project area.

The contractor will implement any measures deemed by the City of West Sacramento to be necessary and feasible to preserve in place, avoid, or minimize impacts to the resource, including, but not limited to, facilitating the appropriate tribal treatment of the find, as necessary. Treatment that preserves or restores the cultural character and integrity of a Tribal Cultural Resource may include Tribal Monitoring, culturally appropriate recovery of cultural objects, and reburial of cultural objects or cultural soil.

Work at the discovery location cannot resume until all necessary investigation and evaluation of the discovery under the requirements of the CEQA, including AB 52, have been satisfied. 430

MITIGATION MONITORING PLAN
Introduction
Public Resources Code section 21081.6 and section 15097 of the California Environmental Quality Act (CEQA) Guidelines require public agencies to establish monitoring or reporting programs for projects approved by a public agency whenever approval involves the adoption of either a mitigated negative declaration or specified environmental findings related to environmental impact reports.

The following is the Mitigation Monitoring Plan (MMP) for the I Street Bridge Deck Conversion for Active Transportation project (proposed project). The intent of the MMP is to aid the City of West Sacramento in its implementation and monitoring of mitigation measures adopted from the I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration.

Mitigation Measures
The mitigation measures are taken from the I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration. The MMP describes the actions that must take place to implement each mitigation measure, the timing of those actions, and the entities responsible for implementing and monitoring the actions.

MMP Components
The components of the attached table, which contains applicable mitigation measures, are addressed briefly, below.

Mitigation Measure: All mitigation measures identified in the I Street Bridge Deck Conversion for Active Transportation Mitigated Negative Declaration.

Action(s): For every mitigation measure, one or more actions are described. The actions delineate the means by which the mitigation measures will be implemented, and, in some instances, the criteria for determining whether a measure has been successfully implemented. Where mitigation measures are particularly detailed, the action may refer back to the measure.

Implementing Party: This item identifies the entity that will undertake the required action.

Timing: Implementation of the action must occur prior to or during some part of project design or construction, or on an ongoing basis. The timing for each measure is identified.

Monitoring Party: The City of West Sacramento is primarily responsible for ensuring that mitigation measures are successfully implemented. Within the City of West Sacramento, a number of departments and divisions would have responsibility for monitoring some aspect of the overall project. Other agencies, such as the Yolo-Solano Air Quality Management District, may also be responsible for monitoring the implementation of mitigation measures. As a result, more than one monitoring party may be identified.

Mitigation Measure AIR-1: Implement Additional Control Measures for Construction Emissions of Fugitive Dust
Additional measures to control dust in Yolo County will be borrowed from YSAQMD’s recommended list of dust control measures and implemented to the extent practicable when the measures have not already been included in and do not conflict with the requirements or other permits and authorizations issued for the project. The following measures are taken from YSAQMD’s Construction Dust Mitigation Measures (YoloSolano Air Quality Management District 2007).  Water all active construction sites at least twice daily. Frequency should be based on the type of operation, soil, and wind exposure.
 Haul trucks shall maintain at least 2 feet of freeboard.  Cover all trucks hauling dirt, sand, or loose materials.  Apply non-toxic binders (e.g., latex acrylic copolymer) to exposed areas after cutand-fill operations and hydroseed area.  Apply chemical soil stabilizers on inactive construction areas (disturbed lands within construction projects that are unused for at least 4 consecutive days).  Plant tree windbreaks on the windward perimeter of construction projects if adjacent to open land.
 Plant vegetative ground cover in disturbed areas as soon as possible.  Cover inactive storage piles.
 Sweep streets if visible soil material is carried out from the construction site.  Treat accesses to a distance of 100 feet from the paved road with a 6- to 12-inch layer of wood chips or mulch.
 Treat accesses to a distance of 100 feet from the paved road with a 6-inch layer of gravel.

Additional measures to control dust in Sacramento County will be borrowed from SMAQMD’s recommended list of dust control measures and implemented to the extent practicable when the measures have not already been included in, and do not conflict with, the requirements of other permits and authorizations issued for the project. The following measures are taken from SMAQMD’s (2021) Guide to Air Quality Assessment in Sacramento County and represent their basic control measures for fugitive dust.  Water all exposed surfaces two times daily. Exposed surfaces include, but are not limited to soil piles, graded areas, unpaved parking areas, staging areas, and access roads.
 Cover or maintain at least 2 feet of free board space on haul trucks transporting soil, sand, or other loose material on the site. Any haul trucks that would be traveling along freeways or major roadways should be covered.

 Use wet power vacuum street sweepers to remove any visible track out mud or dirt onto adjacent public roads at least once a day. Use of dry power sweeping is prohibited.
 Limit vehicle speeds on unpaved roads to 15 mph.
 All roadways, driveways, sidewalks, and parking lots to be paved should be completed as soon as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.

Biological Resources
Mitigation Measure BIO-1: Install Orange Construction Fencing between the Construction Area and Adjacent Sensitive Biological Resources The project proponent and/or its contractor will install orange construction fencing between the construction area and adjacent sensitive biological resource areas.

Sensitive biological resources that occur adjacent to the construction area that could be directly affected by the project include natural communities of special concern; specialstatus wildlife habitats for valley elderberry longhorn beetle; nest sites of Swainson’s hawk, purple martin, or other migratory birds; roosting bats; and protected trees to be avoided. Barrier fencing around sensitive areas will be installed as one of the first orders of work and prior to equipment staging. Before construction begins, the construction contractor will work with the project engineer and a resource specialist to identify the locations for the orange construction fencing and will place stakes around the sensitive resource sites to indicate these locations. Where buffers prescribed by the Yolo HCP/NCCP are not feasible, such as a 100-foot buffer from riparian canopy drip line, buffers appropriate for this active transportation project that connects to an existing bridge crossing will be used as long as they are consistent with the other project mitigation measures (e.g. species-specific non-disturbance buffers) adopted to avoid significant impacts. The protected areas will be designated as environmentally sensitive areas and clearly identified on the construction plans and described in the specifications. To minimize the potential for snakes and other ground-dwelling animals from being caught in the orange construction fencing, the fencing will be placed with at least a 1-foot gap between the ground and the bottom of the orange construction fencing. The exception to this condition is where construction barrier fencing overlaps with erosion control fencing and must be secured to prevent sediment runoff. Barrier fencing will be installed before construction activities are initiated, maintained throughout the construction period, and removed after completion of construction.

Mitigation Measure BIO-2: Conduct Environmental Awareness Training for Construction Employees
The project proponent will retain a qualified biologist to conduct environmental awareness training for construction crews before project implementation. The awareness training will be provided to all construction personnel and will brief them on the need to avoid effects on sensitive biological resources (e.g., native trees, riparian habitat, and special-status species habitats in and adjacent to the construction area).

potential to occur in the project area (including their life history, habitat requirements, and photographs of the species). The training will identify the portions of the project area in which the species may occur, as well as their legal status and protection. The program also will cover the restrictions and guidelines that must be followed by all construction personnel to reduce or avoid effects on these species during project implementation. This will include the steps to be taken if a sensitive species is found within the construction area (i.e., notifying the crew foreman, who will call a designated biologist). In addition, construction employees will be educated about the importance of controlling and preventing the spread of invasive plant infestations. An environmental awareness handout that describes and illustrates sensitive resources to be avoided during project construction and identifies all relevant permit conditions will be provided to each crew member. The crew foreman will be responsible for ensuring that crew members adhere to the guidelines and restrictions. Education programs will be conducted for appropriate new personnel as they are brought on the job during the construction period.

Mitigation Measure BIO-3: Conduct Periodic Biological Monitoring The project proponent will retain a qualified biological monitor for the project who will visit the site a minimum of once per month to ensure that fencing around environmentally sensitive areas is intact and that activities are being conducted in accordance with the agreed upon project schedule and agency conditions of approval.

The monitor will provide the project proponent with a monitoring log for each site visit.

Certain activities will require a biological monitor to be present for the duration of the activity or during the initial disturbance of an area to ensure that impacts on specialstatus species are avoided.

Mitigation Measure BIO-4: Conduct Preconstruction Surveys for Crotch Bumble Bee and Western Bumble Bee and Avoid Active Nests
Pre-construction surveys for active bee nest colonies and associated floral resources (i.e., flowering vegetation on which bees from the colony are observed foraging) no more than 30 days prior to any ground disturbance between March and September.

The purpose of this pre-construction survey would be to identify active nest colonies and associated floral resources in impact areas that could be avoided by construction personnel. The project biologist would establish, monitor, and maintain no-work buffers around nest colonies and floral resources identified during surveys. The size and configuration of the no-work buffer would be based on best professional judgment of the project biologist. At a minimum, the buffer would provide at least 20 feet of clearance around nest entrances and maintain disturbance-free airspace between the nest and nearby floral resources. Construction activities would not occur within the nowork buffers until the colony is no longer active (i.e., no bees are seen flying in or out of the nest for three consecutive days indicating the colony has completed its nesting season and the next season’s queens have dispersed from the colony).

Mitigation Measure BIO-5: Protect Crotch Bumble Bee and Western Bumble Bee Food Plants from Herbicide and Pesticide Use
To minimize impacts on Crotch bumble bee and western bumble bee from pesticide and herbicide drift, application of these chemicals will be limited to the extent feasible and will be conducted using handheld equipment. Herbicides and pesticides will be applied only by applicators with current licenses and/or certifications from the California Department of Pesticide Regulation. The applicator will follow the pesticide and herbicide label directions. Spray nozzles will be kept within 24 inches of target areas during spraying. The most current information on pesticide and herbicide toxicity on wildlife will be used to inform future decisions about their use during project operation.

The project proponent will include suitable native nectar- and pollen-producing plants commonly used as food sources by Crotch bumble bee and western bumble bees in on-site revegetation and erosion control plans. Native plants of the following genera are appropriate for Crotch bumble bee: Antirrhinum, Asclepias, Phacelia, Chaenactis, Clarkia, Dendromecon, Eriogonum, Eschscholzia, Lupinus, Medicago, and Salvia.

Native plants of the following taxa are appropriate for western bumble bee: Asteraceae, Ceanothus, Centaurea, Chrysothamnus, Cirsium, Eriogonum, Geranium, Grindelia, Lupinus, Melilotus, Monardella, Rubus, Penstemon, Solidago, and Trifolium.

Mitigation Measure BIO-7: Conduct Preconstruction Surveys for Western Pond Turtle and Allow Turtles to Leave Work Area Unharmed
To avoid potential injury to or mortality of western pond turtles, the project proponent will retain a qualified biologist to conduct a preconstruction survey for western pond turtles immediately prior to construction activities (including vegetation removal) along the banks of the Sacramento River. The biologist will survey riparian and ruderal habitat within the construction area immediately prior to disturbance if a western pond turtle is found within the immediate work area during the preconstruction survey or during project activities, work will cease in the area until the turtle is able to move out of the work area on its own. Information about the location of turtles seen during the preconstruction survey will be included in the environmental awareness training (Mitigation Measure BIO-2, Conduct Environmental Awareness Training for Construction Employees) and provided directly to the construction crew working in that area to ensure that areas where turtles were observed are inspected each day prior to the start of work to ensure that no turtles are present. Workers will cover open trenches and holes associated with construction activities or design the trenches and holes with escape ramps that can be used during non-working hours. The contractor will inspect open trenches and holes prior to filling and contact a qualified biologist to remove or release any trapped wildlife found in the trenches or holes. If a western pond turtle nest is discovered during the preconstruction survey or during project construction, the project proponent will coordinate with CDFW to determine whether additional avoidance measures (e.g., no-disturbance buffer or monitoring) is prudent.

Mitigation Measure BIO-8: Conduct Preconstruction Surveys for Nesting Migratory Birds, Including Special-Status Birds, and Establish Protective Buffers The project proponent will retain a qualified wildlife biologist to conduct nesting surveys before the start of construction. These nesting surveys will be conducted in conjunction with the Swainson’s hawk and white-tailed kite nesting surveys (see Mitigation Measure BIO-10, Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction) and will include a minimum of three separate surveys to look for active nests of migratory birds, including raptors. Surveys will include a search of all structures, trees, shrubs, ruderal areas, and grassland vegetation that provide suitable nesting habitat within a 0.25-mile (raptors) and a 50-feet500-foot (non-raptors) radius around ofdisturbance areas. Surveys should occur during the height of the breeding season (March 1 to June 1), with one survey occurring in each of the 2 consecutive months within this peak period and the final survey occurring within 1 week of the start of construction. If no active nests are detected during these surveys, no additional measures are required. If an active nest is found in the survey area, a no-disturbance buffer will be established to avoid disturbance or destruction of the nest site until the end of the breeding season (September 15) or until after a qualified wildlife biologist determines that the young have fledged and moved out of the construction area (this date varies by species). The extent of these buffers will be determined by the biologist in coordination with CDFW and will depend on the level of noise or construction disturbance taking place, line-of-sight between the nest and the disturbance, ambient levels of noise and other non-project disturbances, and other topographical or artificial barriers. Suitable buffer distances may vary between species. Fish and Game Code protections for nesting and migratory birds apply regardless of the time of year, and some bird species may nest during the winter and fall months. If an active nest is discovered outside of the typical nesting season, it will be avoided using the same avoidance measures that would be applied during the typical nesting season until such time a qualified wildlife biologist determines that the young have fledged.

Mitigation Measure BIO-9: Conduct Tree Removal during Non-Sensitive Periods for Wildlife
The project proponent will remove or trim trees during the non-breeding season for tree-nesting migratory birds and raptors, and prior to periods when bats would be hibernating (generally between September 15 and October 31). If tree removal cannot be confined to this period, the project proponent will retain a qualified wildlife biologist with knowledge of the wildlife species that could occur in the project area to conduct the appropriate preconstruction surveys and establish no-disturbance buffers for sensitive wildlife species as described under mitigation measures for Swainson’s hawk and white-tailed kite, nesting birds, and roosting bats (see Mitigation Measures BIO-8 and BIO-10 through BIO-13. Implementation of the following measures will avoid and minimize impacts on purple martins, as well as other nesting birds and bats that use the approach structures.

Mitigation Measure BIO-10: Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction
The project proponent will retain a wildlife biologist experienced in surveying for Swainson’s hawk and white-tailed kite to conduct surveys for these species in the spring/summer prior to construction. The surveys will be conducted within the limits of disturbance and in a buffer area up to 0.25 mile from the limits of disturbance. The size of the buffer area surveyed will be based on the type of habitat present and the line-ofsight from the construction area to surrounding suitable breeding habitat. Surveys will follow the methods in Recommended Timing and Methodology for Swainson’s Hawk Nesting Surveys in California’s Central Valley (Swainson’s Hawk Technical Advisory Committee 2000). A minimum of six surveys will be conducted according to these methods. If a variance of the survey distance or number of surveys is necessary, the project proponent will coordinate with CDFW regarding appropriate survey methods based on proposed construction activities. Surveys generally will be conducted from February to July. Survey methods and results will be reported to the project proponent and CDFW.

Mitigation Measure BIO-11: Monitor Active Swainson’s Hawk and White-Tailed Kite Nests during Construction Activities
The proposed project is in an urban area subject to noise and disturbance from vehicle and pedestrian traffic on the existing I Street Bridge and surface streets, and from boat traffic along the Sacramento River; therefore, if Swainson’s hawk or white-tailed kite are present in the project area, they are already exposed to a relatively high level of disturbance under existing conditions. Although the monitoring and non-disturbance buffers prescribed by the Yolo HCP/NCCP are 1,320 feet, because of the existing noise and disturbance in the project area, the monitoring and non-disturbance buffers of 600 feet under the proposed project would be sufficient to avoid take and adverse effects, consistent with the intent of Yolo HCP/NCCP AMM 16, Minimize Take and Adverse Effects on Habitat of Swainson’s Hawk and White-Tailed Kite. Active Swainson’s hawk and white-tailed kite nests within 600 feet of the study area will be monitored during construction. Monitoring will be conducted by a wildlife biologist with experience in monitoring Swainson’s hawk and white-tailed kite nests. The monitor will document the location of active nests, coordinate with the project proponent and CDFW, and record all observations in a daily monitoring log. The monitor will have the authority to temporarily stop work if activities are disrupting nesting behavior to the point of resulting in potential take (i.e., eggs and young chicks are still in the nest, and adults appear agitated and could potentially abandon the nest). The monitor will work closely with the contractor, the project proponent, and CDFW to develop plans for minimizing disturbance, such as modifying or delaying certain construction activities.

A minimum non-disturbance buffer of 600 feet (radius) will be established around all active Swainson’s hawk and white-tailed kite nests. No entry of any kind related to construction will be allowed within this buffer while the nest is active, unless approved by CDFW through issuance of an incidental take permit or through consultation during project construction.

including line-of-sight, topography, type of disturbance, existing ambient noise and disturbance levels, and other relevant factors. Entry into the buffer for construction activities will be granted when the biological monitor determines that the young have fledged and are capable of independent survival, or that the nest has failed and the nest site is no longer active. All buffer adjustments will be approved by CDFW.

Mitigation Measure BIO-12: Avoid and Minimize Impacts on Purple Martins during Construction Activities
No construction activity that results in ground disturbance, loud noises, and/or vibrations will be conducted within 100 feet of the edge of the purple martin colony during the purple martin nesting season (March 15 to August 15).

Mitigation Measure BIO-13: Conduct Preconstruction Surveys for Tree Roosting Bats and Implement Protective Measures
To avoid and minimize potential impacts on pallid bat, western red bat, and nonspecial-status bat species from the removal of trees and construction noise and vibration, the project proponent will implement the following actions.

Preconstruction Surveys
One month prior to tree trimming or removal, a qualified biologist will examine trees to be removed or trimmed and trees or structures within the vicinity of construction activities (a minimum of 100 feet) for suitable bat roosting habitat. High-quality habitat features (e.g., crevices, large tree cavities, basal hollows, loose or peeling bark, larger snags) will be identified, and the area around these features searched for bats and bat sign (e.g., guano, culled insect parts, staining). Riparian woodland and stands of mature broadleaf trees will be considered potential habitat for solitary foliage-roosting bat species.

If suitable roosting habitat and/or bat sign is detected, biologists will conduct an evening visual emergence survey of the source habitat feature, from a half hour before sunset to 1–2 hours after sunset for a minimum of 2 nights. Full-spectrum acoustic detectors will be used during emergence surveys to assist in species identification. If site security allows, detectors should be set to record bat calls for the duration of each night. All emergence and monitoring surveys will be conducted during favorable weather conditions (calm nights with temperatures conducive to bat activity and no precipitation Retain a qualified

Protective Measures
Protective measures may be necessary if it is determined that bats are using trees in the study area as roost sites, or if sensitive bats species are detected during acoustic monitoring. The following measures will be implemented when roosts are found within trees planned for removal according to the timing discussed above. Specific measures will be approved by the project proponent and CDFW prior to excluding bats from occupied roosts.  Trees planned for removal will have exclusion devices installed between September 15 and October 31 to avoid affecting maternal and hibernating bat roosts. The exact timing of removal and demolition will be determined based on preconstruction surveys of trees.
Exclusion from roosts will take place late in the day or in the evening to reduce the likelihood of evicted bats falling prey to diurnal predators and will take place during weather and temperature conditions conducive to bat activity.  Biologists experienced with bats and bat evictions will carry out or oversee the exclusion tasks and will monitor tree trimming and removal.  Trees that provide suitable roost habitat will be removed in pieces, rather than felling the entire tree and should be done late in the day or in the evening to reduce the likelihood of evicted bats falling prey to diurnal predators and will take place during warm weather conditions conducive to bat activity.
 Structural changes may be made to a known roost proposed for removal, to create conditions in the roost that are undesirable to roosting bats and encourage the bats to leave on their own (e.g., open additional portals so that temperature, wind, light and precipitation regime in the roost change).
 Structural changes to the roost will be authorized by CDFW and will be performed during the appropriate exclusion timing (listed above) to avoid harming bats.  Non-injurious harassment at the roost site, such as ultrasound deterrents or other sensory irritants, may be used to encourage bats to leave on their own.  One-way door devices will be used where appropriate to allow bats to leave the roost but not to return.
 Prior to tree removal/trimming and after other eviction efforts have been attempted, any confirmed roost site will be gently shaken or repeatedly struck with a heavy implement such as a sledgehammer or an axe. Several minutes should pass before felling trees or trimming limbs to allow bats time to arouse and leave the roost. A biological monitor will search downed vegetation for dead and injured bats. The presence of dead or injured bats will be reported to CDFW. Injured bats will be transported to the nearest CDFW-permitted wildlife rehabilitation facility.  No construction activity that results in ground disturbance, loud noises, and/or vibrations will be conducted within 100 feet of the edge of occupied roosts during the maternity season (April 1 to September 15). In addition, no construction-related vehicles or machinery shall be operated or stored beneath the colony during this 441

period or until a qualified biologist determines that the purple martins have completed nesting and are no longer occupying the structure.  Biologists experienced with bats will monitor construction activities within 100 feet of identified roosts to ensure that roosting bats are not disturbed.

Mitigation Measure BIO-14: Avoid the Introduction and Spread of Invasive Plants The project proponent or its contractor will be responsible for avoiding the introduction of new invasive plants and the spread of invasive plants previously documented in the project’s study area. The following measures will be implemented during and after construction.
 Educate construction supervisors and managers on weed identification and the importance of controlling and preventing the spread of invasive weeds.  Dispose of invasive species material removed during project construction offsite at an appropriate disposal facility to avoid the spread of invasive plants into natural areas.
 Minimize surface disturbance to the greatest extent feasible to complete the work.  Restore to pre-project conditions all temporarily disturbed areas, including project staging areas, within one year of completion of project construction.  Use weed-free imported erosion-control materials (or rice straw in upland areas).  Use locally grown native plant stock and native or naturalized (noninvasive) grass seed during revegetation.
 If feasible, remove black locust trees from the riparian forest in and adjacent to the impact area on the Sacramento side of the bridge and any red sesbania trees in or adjacent to the impact area on the West Sacramento side.

Mitigation Measure BIO-15: Compensate for Loss of Protected Trees Within 1 year prior to construction, the project proponent will conduct a preconstruction inventory of all protected trees to be removed within the project area. The inventory will include the location, species, diameter of all trunks, approximate height and canopy diameter, and approximate age, in support of a tree permit for removal of the protected trees. All conditions of the tree permit will be implemented.

The project proponent will mitigate for the loss of protected trees using one or a combination of the two following options.
 If feasible, plant replacement trees at or near the location of the tree removal.

Replacement trees will be required at a ratio of 1:1 (i.e., 1-inch diameter of replacement tree planted for every 1-inch diameter of tree removed). Replacement trees will be of the same species. Mitigation will be subject to approval by the City’s tree administrator and will take into account species affected, replacement species, location, health and vigor, habitat value, and other factors to determine fair compensation for tree loss. Replacement trees will be monitored annually for 3 years to document vigor and survival. If any of the replacement trees die within 3 years of the initial planting, the project proponent will plant additional replacement trees and monitor them until all trees survive for a minimum of 3 years after planting.

Cultural Resources
Mitigation Measure CUL-1: Implement Measures to Protect Previously Unidentified Cultural Resources
 Construction shall stop if potential cultural resources are encountered. It is possible that previous activities have obscured surface evidence of cultural resources. If signs of an archeological site, such as any unusual amounts of stone, bone, or shell, are uncovered during grading or other construction activities, work will be halted within 100 feet of the find and the City of West Sacramento will be notified. A qualified archeologist will be consulted for an onsite evaluation. If the site appears to be eligible for listing in state or federal registers, additional mitigation, such as further testing for evaluation or data recovery, may be necessary.  In the event resources are discovered, the City of West Sacramento will retain a qualified archaeologist to assess the find and to determine whether the resource requires further study. Any previously undiscovered resources found during construction will be recorded on appropriate California Department of Parks and Recreation 523 forms and evaluated for significance under all applicable regulatory criteria.
 All work will stop in the immediate vicinity of the find, and, if the find is determined to be an important cultural resource, the City of West Sacramento will make available contingency funding and a time allotment sufficient to allow recovery of an archaeological sample or to implement an avoidance measure. Construction work may continue on other parts of the project while archaeological mitigation takes place.

If any suspected tribal cultural resources are discovered during ground disturbing construction activities, all work shall cease within 100 feet of the find, or an agreed upon distance based on the project area and nature of the find. A Tribal Representative from a California Native American tribe that is traditionally and culturally affiliated with a geographic area shall be immediately notified and shall determine if the find is a tribal cultural resource (Pub. Resources Code Section 21074). The Tribal Representative will make recommendations for further evaluation and treatment as necessary.

When avoidance is infeasible, preservation in place is the preferred option for mitigation of tribal cultural resources under CEQA, and every effort shall be made to preserve the resources in place, including through project redesign, if feasible. Culturally appropriate treatment may be, but is not limited to, processing materials for reburial, minimizing handling of cultural objects, leaving objects in place within the landscape, or returning objects to a location within the project area where they will not be subject to future impacts. Permanent curation of tribal cultural resources will not take place unless approved in writing by the California Native American tribe that is traditionally and culturally affiliated with the project area.

The contractor will implement any measures deemed by the City of West Sacramento to be necessary and feasible to preserve in place, avoid, or minimize impacts to the resource, including, but not limited to, facilitating the appropriate tribal treatment of the find, as necessary. Treatment that preserves or restores the cultural character and integrity of a Tribal Cultural Resource may include Tribal Monitoring, culturally appropriate recovery of cultural objects, and reburial of cultural objects or cultural soil.

Re: Public Comments Received Regarding I Street Bridge Deck Conversion for Active Transportation Initial Study/Proposed Mitigated Negative Declaration Introduction
The City of West Sacramento (City) is evaluating the proposed conversion of the upper deck of the I Street Bridge so it can be used only for active transportation. The project would include construction of new Americans with Disabilities Act (ADA)-compliant access ramps to the upper deck and connections to the existing pedestrian, bicycle, and trail network on each side of the Sacramento River. The City prepared an Initial Study/proposed Mitigated Negative Declaration1 to provide the public, responsible agencies, and trustee agencies with information about the potential environmental effects of the I Street Bridge Deck Conversion for Active Transportation project (proposed project). The document was prepared following the requirements of the California Environmental Quality Act of 1970, as amended (CEQA) (Public Resources Code Section 21000 et seq.) and the State CEQA Guidelines (Title 14 California Code of Regulations Section 15000 et seq.).

The Initial Study and proposed Mitigated Negative Declaration were circulated for public review and comment from October 14 to November 14, 2022.

13 Discussion of Comments from Sacramento Metropolitan Air Quality Management District, Letter
Comment 1
The commenter suggests that the mitigation measures adopted to reduce the impacts of development described in the Railyards Specific Plan in Sacramento are applicable to the Sacramento portion of the proposed project. The comment also suggests that the mitigation measure AIR-1 in the Initial Study and Mitigated Negative Declaration included to reduce the air quality impacts of the proposed project to less than significant levels be supplemented with the contents of specific mitigation measures in the Railyards Specific Plan Update Environmental Impact Report (EIR). While located within the southwestern portion of the specific plan area, the proposed project is not a component of the Railyards Specific Plan Update project and therefore was not part of the impact analysis described in the Railyards Specific Plan Update Environmental Impact Report.

Further the environmental analysis for the proposed project does not tier from the Railyards Specific Plan Update EIR. The mitigation measures included in the Initial Study and proposed Mitigated Negative Declaration reduce the impacts of the proposed project to less-than-significant levels. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 2
This comment recommends that the agency responsible for contracting the proposed project coordinate with Sac Metro Air District regarding the implementation of a mitigation measure applicable to the Sacramento Railyards Specific Plan Update EIR. The proposed project is not part of the Sacramento Railyards Specific Plan Update project. The mitigation measures included in the Initial Study and proposed Mitigated Negative Declaration reduce the impacts of the proposed project to less-than-significant levels. The proposed project will comply with the Sac Metro Air District rules that are in effect at the time of construction. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 3
Sac Metro Air District recommends that air quality mitigation measures be included in project construction bid specifications. This recommendation is acceptable. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 4
This comment references the list of the most common Sac Metro Air District rules currently in effect that are applicable to construction activities. Mitigation measure AIR-1 in the Initial Study and proposed Mitigated Negative Declaration, includes measures from SMAQMD’s (2021) Guide to Air Quality Assessment in Sacramento County and represent their basic control measures for fugitive dust which, when implemented, will reduce air quality impacts to less-than-significant levels. The proposed project will comply with the applicable Sac Metro Air District rules that are in effect at the time of construction. No changes to the Initial Study or Mitigated Negative Declaration are necessary. 460

17 Discussion of Comments from California Department of Fish and Wildlife Comment 1
This comment is introductory and describes the regulatory role of the California Department of Fish and Wildlife (CDFW) and summarizes the proposed project. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 2
This comment describes the regulatory protections for nesting and migratory birds and birds of prey.

The comment reiterates some of the content of proposed Mitigation Measure BIO-8 (Conduct Preconstruction Surveys for Nesting Migratory Birds, Including Special-Status Birds, and Establish Protective Buffers) and the survey area proposed in it. The comment recommends a larger preconstruction survey area and other revisions to the measure. To address this comment the text of Mitigation Measure BIO-8 in the Mitigated Negative Declaration is revised as follows, with revisions shown using underline for additions and strikethrough for deletions.

Mitigation Measure BIO-8: Conduct Preconstruction Surveys for Nesting Migratory Birds, Including Special-Status Birds, and Establish Protective Buffers The project proponent will retain a qualified wildlife biologist to conduct nesting surveys before the start of construction. These nesting surveys will be conducted in conjunction with the Swainson’s hawk and white-tailed kite nesting surveys (see Mitigation Measure BIO-10, Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction) and will include a minimum of three separate surveys to look for active nests of migratory birds, including raptors. Surveys will include a search of all structures, trees, shrubs, ruderal areas, and grassland vegetation that provide suitable nesting habitat within a 0.25-mile (raptors) and a 50- feet500-foot (non-raptors) radius around ofdisturbance areas. Surveys should occur during the height of the breeding season (March 1 to June 1), with one survey occurring in each of the 2 consecutive months within this peak period and the final survey occurring within 1 week of the start of construction. If no active nests are detected during these surveys, no additional measures are required. If an active nest is found in the survey area, a no-disturbance buffer will be established to avoid disturbance or destruction of the nest site until the end of the breeding season (September 15) or until after a qualified wildlife biologist determines that the young have fledged and moved out of the construction area (this date varies by species). The extent of these buffers will be determined by the biologist in coordination with CDFW and will depend on the level of noise or construction disturbance taking place, line-of-sight between the nest and the disturbance, ambient levels of noise and other non-project disturbances, and other topographical or artificial barriers. Suitable buffer distances may vary between species. Fish and Game Code protections for nesting and migratory birds apply regardless of the time of year, and some bird species may nest during the winter and fall months. If an active nest is discovered outside of the typical nesting season, it will be avoided using the same avoidance measures that would be applied during the typical nesting season until such time a qualified wildlife biologist determines that the young have fledged.

Comment 3
The portion of the project in the city of West Sacramento is within the Yolo Habitat Conservation Plan/Natural Communities Conservation Plan (Yolo HCP/NCCP) planning area. This comment 464
Public Comments Received Regarding I Street Bridge Deck Conversion for Active Transportation Initial Study/Proposed Mitigated Negative Declaration
18 recommends including the full text of avoidance and minimization measures (AMMs) from the Yolo HCP/NCCP that apply to the proposed project and an explanation of how the project mitigation measures incorporate aspects of the Yolo HCP/NCCP AMMs. The comment also recommends revisions to mitigation measures to include requirements from Yolo HCP/NCCP AMMs 14 and 16, which address minimization of take of western pond turtle and adverse effects on habitat of Swainson’s hawk and white-tailed kite.

The Yolo HCP/NCCP includes 21 AMMs, 11 of which are applicable to the proposed project (AMM1, Establish Buffers, AMM3, Confine and Delineate Work Area, AMM4, Cover Trenches and Holes during Construction and Maintenance, AMM5, Control Fugitive Dust, AMM6 Conduct Worker Training, AMM7, Control Nighttime Lighting of Project Construction Sites, AMM8, Avoid and Minimize Effects of Construction Staging Areas and Temporary Work Areas, AMM9, Establish Buffers around Sensitive Natural Communities, AMM10 Avoid and Minimize Effects on Wetlands and Waters, AMM14, Minimize Take and Adverse Effects on Habitat of Western Pond Turtle, AMM16, Minimize Take and Adverse Effects on Habitat of Swainson’s Hawk and White-Tailed Kite).

The measures included in the Mitigated Negative Declaration as mitigation for biological impacts of the project are consistent with the relevant measures in the Yolo HCP/NCCP to reduce impacts on special-status species.

To help clarify the consistency with the Yolo HCP/NCCP, six mitigation measures were revised in the Mitigated Negative Declaration. Mitigation Measure BIO-1 (Install Orange Construction Fencing between the Construction Area and Adjacent Sensitive Biological Resources) is revised to clarify the approach to buffers for this active transportation project that connects to an existing bridge crossing as compared to the Yolo HCP/NCCP. Mitigation Measure BIO-7 (Conduct Preconstruction Surveys for Western Pond Turtle and Allow Turtles to Leave Work Area Unharmed) is revised to include specific language from Yolo HCP/NCCP AMM 14 (Minimize Take and Adverse Effects on Habitat of Western Pond Turtle). Mitigation Measure BIO-9 (Conduct Tree Removal during Non-Sensitive Periods for Wildlife) is revised to specifically mention white-tailed kite. Mitigation Measures BIO-10 and BIO-11 (Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction; Monitor Active Swainson’s Hawk and White-Tailed Kite Nests during Construction Activities) also are revised to specifically mention white-tailed kite (these measures were previously specific to Swainson’s hawk). Mitigation Measures BIO-10 and BIO-11 are consistent with the Yolo HCP/NCCP AMM 16 in that they both implement measures to avoid and minimize take and adverse effects on both white-tailed kite and Swainson’s hawk. However, because the project is in an urban area that is subject to noise and disturbance from vehicle and pedestrian traffic on the existing I Street Bridge and surface streets, and from boat traffic along the Sacramento River, a 600 foot monitoring and non-disturbance buffer are assumed to be sufficient to avoid and minimize take, avoid adverse effects on these species, and reduce the impact to less-than-significant levels because if Swainson’s hawk or white-tailed kite are present in the project area, they are already exposed to a relatively high level of disturbance under existing conditions. Mitigation Measure BIO-14 (Avoid the Introduction and Spread of Invasive Plants) is revised to include restoration of all temporarily disturbed areas to pre-project conditions within one year of completion of project construction.

Revisions to the mitigation measures are shown below, with revisions shown using underline for additions and strikethrough for deletions.

19 Mitigation Measure BIO-1: Install Orange Construction Fencing between the Construction Area and Adjacent Sensitive Biological Resources
The project proponent and/or its contractor will install orange construction fencing between the construction area and adjacent sensitive biological resource areas. Sensitive biological resources that occur adjacent to the construction area that could be directly affected by the project include natural communities of special concern; special-status wildlife habitats for valley elderberry longhorn beetle; nest sites of Swainson’s hawk, purple martin, or other migratory birds; roosting bats; and protected trees to be avoided. Barrier fencing around sensitive areas will be installed as one of the first orders of work and prior to equipment staging. Before construction begins, the construction contractor will work with the project engineer and a resource specialist to identify the locations for the orange construction fencing and will place stakes around the sensitive resource sites to indicate these locations. Where buffers prescribed by the Yolo HCP/NCCP are not feasible, such as a 100-foot buffer from riparian canopy drip line, buffers appropriate for this active transportation project that connects to an existing bridge crossing will be used as long as they are consistent with the other project mitigation measures (e.g. species-specific non-disturbance buffers) adopted to avoid significant impacts. The protected areas will be designated as environmentally sensitive areas and clearly identified on the construction plans and described in the specifications. To minimize the potential for snakes and other ground-dwelling animals from being caught in the orange construction fencing, the fencing will be placed with at least a 1-foot gap between the ground and the bottom of the orange construction fencing. The exception to this condition is where construction barrier fencing overlaps with erosion control fencing and must be secured to prevent sediment runoff.

Barrier fencing will be installed before construction activities are initiated, maintained throughout the construction period, and removed after completion of construction.

Mitigation Measure BIO-7: Conduct Preconstruction Surveys for Western Pond Turtle and Allow Turtles to Leave Work Area Unharmed
To avoid potential injury to or mortality of western pond turtles, the project proponent will retain a qualified biologist to conduct a preconstruction survey for western pond turtles immediately prior to construction activities (including vegetation removal) along the banks of the Sacramento River. The biologist will survey riparian and ruderal habitat within the construction area immediately prior to disturbance if a western pond turtle is found within the immediate work area during the preconstruction survey or during project activities, work will cease in the area until the turtle is able to move out of the work area on its own. Information about the location of turtles seen during the preconstruction survey will be included in the environmental awareness training (Mitigation Measure BIO-2, Conduct Environmental Awareness Training for Construction Employees) and provided directly to the construction crew working in that area to ensure that areas where turtles were observed are inspected each day prior to the start of work to ensure that no turtles are present. Workers will cover open trenches and holes associated with construction activities or design the trenches and holes with escape ramps that can be used during non-working hours. The contractor will inspect open trenches and holes prior to filling and contact a qualified biologist to remove or release any trapped wildlife found in the trenches or holes. If a western pond turtle nest is discovered during the preconstruction survey or during project construction, the project proponent will coordinate with CDFW to determine whether additional avoidance measures (e.g., no-disturbance buffer or monitoring) is prudent.

20 Mitigation Measure BIO-9: Conduct Tree Removal during Non-Sensitive Periods for Wildlife
The project proponent will remove or trim trees during the non-breeding season for treenesting migratory birds and raptors, and prior to periods when bats would be hibernating (generally between September 15 and October 31). If tree removal cannot be confined to this period, the project proponent will retain a qualified wildlife biologist with knowledge of the wildlife species that could occur in the project area to conduct the appropriate preconstruction surveys and establish no-disturbance buffers for sensitive wildlife species as described under mitigation measures for Swainson’s hawk and white-tailed kite, nesting birds, and roosting bats (see Mitigation Measures BIO-8 and BIO-10 through BIO-13). Implementation of the following measures will avoid and minimize impacts on purple martins, as well as other nesting birds and bats that use the approach structures.

Mitigation Measure BIO-10: Conduct Focused Surveys for Nesting Swainson’s Hawk and White-Tailed Kite prior to Construction
The project proponent will retain a wildlife biologist experienced in surveying for Swainson’s hawk and white-tailed kite to conduct surveys for these species in the spring/summer prior to construction. The surveys will be conducted within the limits of disturbance and in a buffer area up to 0.25 mile from the limits of disturbance. The size of the buffer area surveyed will be based on the type of habitat present and the line-of-sight from the construction area to surrounding suitable breeding habitat. Surveys will follow the methods in Recommended Timing and Methodology for Swainson’s Hawk Nesting Surveys in California’s Central Valley (Swainson’s Hawk Technical Advisory Committee 2000). A minimum of six surveys will be conducted according to these methods. If a variance of the survey distance or number of surveys is necessary, the project proponent will coordinate with CDFW regarding appropriate survey methods based on proposed construction activities. Surveys generally will be conducted from February to July. Survey methods and results will be reported to the project proponent and CDFW.

Mitigation Measure BIO-11: Monitor Active Swainson’s Hawk and White-Tailed Kite Nests during Construction Activities
The proposed project is in an urban area subject to noise and disturbance from vehicle and pedestrian traffic on the existing I Street Bridge and surface streets, and from boat traffic along the Sacramento River; therefore, if Swainson’s hawk or white-tailed kite are present in the project area, they are already exposed to a relatively high level of disturbance under existing conditions. Although the monitoring and non-disturbance buffers prescribed by the Yolo HCP/NCCP are 1,320 feet, because of the existing noise and disturbance in the project area, the monitoring and non-disturbance buffers of 600 feet under the proposed project would be sufficient to avoid take and adverse effects, consistent with the intent of Yolo HCP/NCCP AMM 16, Minimize Take and Adverse Effects on Habitat of Swainson’s Hawk and White-Tailed Kite.

Active Swainson’s hawk and white-tailed kite nests within 600 feet of the study area will be monitored during construction. Monitoring will be conducted by a wildlife biologist with experience in monitoring Swainson’s hawk and white-tailed kite nests. The monitor will document the location of active nests, coordinate with the project proponent and CDFW, and record all observations in a daily monitoring log. The monitor will have the authority to temporarily stop work if activities are disrupting nesting behavior to the point of resulting in 467

21 potential take (i.e., eggs and young chicks are still in the nest, and adults appear agitated and could potentially abandon the nest). The monitor will work closely with the contractor, the project proponent, and CDFW to develop plans for minimizing disturbance, such as modifying or delaying certain construction activities.

A minimum non-disturbance buffer of 600 feet (radius) will be established around all active Swainson’s hawk and white-tailed kite nests. No entry of any kind related to construction will be allowed within this buffer while the nest is active, unless approved by CDFW through issuance of an incidental take permit or through consultation during project construction. The buffer size may be modified based on site-specific conditions, including line-of-sight, topography, type of disturbance, existing ambient noise and disturbance levels, and other relevant factors. Entry into the buffer for construction activities will be granted when the biological monitor determines that the young have fledged and are capable of independent survival, or that the nest has failed and the nest site is no longer active. All buffer adjustments will be approved by CDFW.

Mitigation Measure BIO-14: Avoid the Introduction and Spread of Invasive Plants The project proponent or its contractor will be responsible for avoiding the introduction of new invasive plants and the spread of invasive plants previously documented in the project’s study area. The following measures will be implemented during and after construction.  Educate construction supervisors and managers on weed identification and the importance of controlling and preventing the spread of invasive weeds.  Dispose of invasive species material removed during project construction offsite at an appropriate disposal facility to avoid the spread of invasive plants into natural areas.  Minimize surface disturbance to the greatest extent feasible to complete the work.  Restore to pre-project conditions all temporarily disturbed areas, including project staging areas, within one year of completion of project construction.  Use weed-free imported erosion-control materials (or rice straw in upland areas).  Use locally grown native plant stock and native or naturalized (noninvasive) grass seed during revegetation.
 If feasible, remove black locust trees from the riparian forest in and adjacent to the impact area on the Sacramento side of the bridge and any red sesbania trees in or adjacent to the impact area on the West Sacramento side.

26 Discussion of Comments from Department of Toxic Substances Control Comment 1
This comment summarizes the requirement to obtain prior written approval from the Department of Toxic Substances Control (DTSC) before conducting any soil disturbing activities within the study area of a DTSC cleanup site. It also notes that the project intersects multiple DTSC cleanup sites in the Sacramento Railyards property. The Initial Study acknowledges this on pages 2-90 to 2-92 and states that any project work conducted in this area must and would comply with the land use covenants (LUC). According to the 2015 LUC for the Sacramento Railyards property and the DTSC, the area, as remediated and when used in compliance with the environmental restrictions of the LUC, does not present an unacceptable risk to present and future human health or safety or the environment. The project will be constructed in compliance with all applicable regulatory requirements. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 2
This comment suggests that regulatory concurrence from an environmental regulatory agency indicating the project site is safe for construction and the proposed use be obtained. The project will be constructed in compliance with all applicable regulatory requirements. The at-grade portions of the project site are currently in use as, or are part of separate approved projects for, active transportation or general pedestrian facilities (North Riverwalk Trail. Sacramento River Parkway, pathways within Sacramento Valley Station). No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 3
This comment requests the Initial Study identify mechanisms to initiate any required investigation and/or remediation and the government agency who will be responsible for providing appropriate regulatory oversight. Mitigation Measure HAZ-3 requires that prior to construction, a Phase II environmental site assessment be conducted in conformance with the American Society for Testing and Materials Standard Practice E1527-05. It further requires that all environmental investigation, sampling, and remediation activities associated with the project be conducted under a work plan approved by the regulatory oversight agency and will be conducted by the appropriate environmental professional consistent with Phase II environmental site assessment requirements. The specific oversight agencies will be identified in the Phase II assessment and the project will be constructed in compliance with all applicable regulatory requirements. The mechanisms to initiate investigations identified as needed during project ground disturbing activities will be included in the Health and Safety Plan required by Mitigation Measure HAZ-1. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 4
This comment notes the potential for polychlorinated biphenyl (PCB) caulk to be present on the existing bridge. This possibility is acknowledged. The Phase II environmental site assessment required by Mitigation Measure HAZ-3 will include sampling and laboratory analysis to confirm the presence of hazardous materials in the project limits. The project will be constructed in compliance with all applicable regulatory requirements. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

30 Discussion of Comments from Sacramento Municipal Utility District Comment 1
This comment requests that the Initial Study acknowledge potential impacts related to transmission and distribution line easements, utility line routing, electrical load needs/requirements, energy efficiency, climate change, cumulative impacts related to increased electrical delivery and the potential need to relocate SMUD infrastructure. Each utility supplier will be contacted during final design of the project to coordinate issues such as the need for transmission line easements and utility line routing in the project limits, electrical loading, and to avoid or minimize service interruptions during project construction. Increased electrical delivery to serve this project is not anticipated.

Potential impacts of the project relating to climate change are discussed in the Initial Study, starting on page 2-83. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 2
This comment suggests the addition of specific text to the Initial Study so that the provided details related to SMUD’s existing electrical infrastructure in the city of Sacramento are included. The infrastructure within the project’s limits of permanent and temporary disturbance, as noted in the letter, is recognized. The City will coordinate with utility service providers during preparation of the final project design, and prior to and during construction, to resolve issues such as the need for transmission line easements and utility line routing in the project limits, and electrical loading. No changes to the Initial Study or Mitigated Negative Declaration are necessary.

Comment 3
This comment requests that SMUD be involved in discussions related to electrical utilities and asks that their comments be shared with project planners and project proponents. As mentioned above, the City will coordinate with utility service providers prior to and during construction. No changes to the Initial Study or Mitigated Negative Declaration are necessary. 477
