Executive Summary
The Highway Safety Improvement Program (HSIP) Cycle 9 – Pedestrian and Median Improvements (Project) is located at 14 intersections in the City of West Sacramento, Yolo County, California. The City of West Sacramento (City) Capital Projects and Transportation Department (CPTD) is planning on making minor pedestrian and median improvements at 14 intersections. The intersection improvements will include upgrades such as crosswalk and crosswalk striping, new signage (stop and yield), improved or new Americans with Disability Act (ADA) accessibility, curb ramps and curb ramp extensions, rectangular rapid flashing beacon (RRFB) pole installation, new sidewalks, installation of raised medians and islands, and elimination of some turning movements to improve safety. The Project will install these improvements at 14 intersections: Lake Washington Boulevard and Southport Parkway, Lake Washington Boulevard and Westbridge Plaza Driveway, Jefferson Boulevard and 15th Street, Jefferson Boulevard at 11th Street, Sacramento Avenue and Sunset Avenue, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Reuter Drive at Andrews Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Quail Road to Columbus Road Shared Use Path, Columbus Road at Stonegate Elementary School and Shared Use Path, and La Jolla Street at Stonegate Elementary School. The purpose of the Project is to enhance the multi-modal transportation network by installing redesigned pedestrian and bicycle crossings. Eight intersections will involve soil disturbance activities and a Preliminary Site Investigation (PSI) was performed to evaluate potential impacts from historical use. The California Department of Transportation (Caltrans) Local Assistance is implementing the safety improvements as part of the HSIP Federal Project No. HSIPL-047, 049, and 050.

WRECO performed a PSI at two of the intersections, where installation of flashing beacons will involve soil disturbance. WRECO reviewed Project improvement plans, historical imagery, and regulatory database sites, to evaluate constituents of concern (COC) at the intersections. Potential COCs include the following:
• Potential aerially deposited lead (ADL) due to leaded gasoline automobile exhaust near roadways with exposed soils prior to 1990;
• Potential organochlorine pesticides (OCP) and organophosphorus pesticides (OPP), heavy metals, and petroleum hydrocarbons (diesel and motor oil) from historical agricultural operations;
• Potential petroleum hydrocarbons (gasoline, diesel, and used oil) and volatile organic compounds (VOC), from leaking underground storage tank (LUST) sites within the Project vicinity; and
• Treated wood utility poles along the roadways have pole-mounted transformers which may contain polychlorinated biphenyls (PCB) and semi-volatile organic compounds (SVOC), and treated wood has metals (arsenic, chromium, and copper) and polynuclear aromatic hydrocarbons (PAH; creosote and pentachlorophenol), which can impact shallow soil.

This report presents the results of the PSI conducted by WRECO for eight intersections, as part of the proposed Project. The PSI was performed in accordance with the American Society for Testing and Materials (ASTM) International Standard E1903-11, Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process and Caltrans ‘Local Assistance Procedures Manual and Caltrans’ Standard Environmental Reference (SER), Volume 1: Guidance Attachment 3

for Compliance, Chapter 10 - Hazardous Materials, Hazardous Waste, and Contamination. The PSI was performed to verify the presence/absence of COC, to evaluate the available options for soil disposal or reuse, and to provide specific guidance for waste management and worker safety during construction.

On August 11, 2021, WRECO conducted a site investigation that included sampling 13 borings, B-1 to B-13, at eight of the 14 intersections based on preliminary analysis of publicly available hazardous materials databases and consultation with Caltrans. The eight intersections include:

Jefferson Boulevard at 11th Street, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Columbus Road at Stonegate Elementary School and Shared Use Path, and La Jolla Street at Stonegate Elementary School. A Direct Push Technology (DPT) rig was used to take continuous core soil samples to 5 feet below ground surface (ft bgs). DPT uses a hydraulically operated percussion hammer along with vehicle weight to advance the sampling barrel with an acetate liner used to contain the soil sample. The liners were cut into specific depth intervals, 0-1, 1-2, and 2-3 ft bgs, per Caltrans protocol for ADL testing, and analyzed for lead and pH using Environmental Protection Agency (EPA) Methods 6020 and 9045C, respectively.

Detectable lead concentrations for sampling depth 0-1 feet ranged from 2.5 to 41 milligrams per kilogram (mg/kg); 1-2 ft ranged from 2.8 to 130 mg/kg; and 2-3 ft ranged from 2.7 to 150 mg/kg.

The pH values ranged from 5.32 to 8.38, which are within the threshold (greater than 2 and less than 12.5) for state waste criteria reuse or disposal to a Class III composite-lined landfill.

Four soil samples (B-5N [comp], B-6S [comp], B-6S [1-2], and B-6S [2-3]) had lead concentrations exceeding 10 times the Soluble Threshold Limit Concentration (STLC) regulatory limit of 5 milligrams per liter (mg/L) and were further analyzed using California Waste Extraction Test (CA WET). Laboratory results indicated that STLC lead concentrations ranged from 2.2 to

7.9 mg/L, and samples B-6S (comp) (5.2 mg/L), B-6S (1-2) (7.9 mg/L), and B-6S (2-3) (7.3 mg/L) exceeded the STLC regulatory limit, and were further analyzed using the toxicity characteristic leaching procedure (TCLP). Laboratory results indicated the TCLP concentrations were below detection limits for all samples from B-6S (as listed above), and the soil can be pre-classified as California hazardous (with respect to lead). Detectable lead concentrations exceeded the Regional Water Quality Control Board (RWQCB) Environmental Screening Levels (ESL) for residential, but not for construction worker or commercial/industrial exposure.

Samples from each boring were homogenized in the laboratory and analyzed for additional COCs that included pesticides (OPP and OCP) (EPA Methods 8141 and 8081), Total Petroleum Hydrocarbons (TPH) as gasoline and diesel (full range) (EPA Method 8015), VOCs (EPA Method 8260), PCBs (EPA Method 8082), SVOCs (EPA Method 8270), PAHs (EPA Method 8310), and California Administrative Metals (CAM) 17 Metals (EPA Method 6000/7000).

All concentrations of metals, pesticides (OCP/OPP), PAHs, TPH (as diesel, hydraulic, kerosene, mineral oil, and gasoline), VOCs, and PCBs were below detection limits. Concentrations of TPH as motor oil ranged from ND (Not Detected) to 420 mg/kg (B-6S [comp]).

Three samples, B-11W (comp), B-12E (comp), and B-13W (comp), had detectable pesticide concentrations of chlordane (55 mg/kg), DDE/DDT (3.5/3.4 mg/kg), and DDE/DDT and dieldrin (13/6 mg/kg and 11 mg/kg), respectively, that exceeded 10 times the STLC and were further analyzed using CA WET. Laboratory results indicated that STLC concentrations were all below detection limits, and the soil in these areas (Poplar Avenue, Columbus Road, and La Jolla Street) is pre-classified as Non-hazardous (with respect to these pesticides). Detectable concentrations did not exceed the RWQCB ESLs for residential, construction worker, and commercial/industrial exposure.

Thirteen composite samples had detectable CAM 17 Metals concentrations of arsenic that ranged from 2.0 to 6.3 mg/kg; barium ranged from 56 to 120 mg/kg; chromium ranged from 31 to 66 mg/kg; cobalt ranged from 8.2 to 48 mg/kg; copper ranged from 7.3 to 38 mg/kg; lead ranged from

5.8 to 110 mg/kg; nickel ranged from 31 to 80 mg/kg; silver ranged from 1.1 to 2.8 mg/kg; vanadium ranged from 30 to 63 mg/kg; and zinc ranged from 30 to 130 mg/kg. Sample B-6S had a detectable mercury concentration of 0.14 mg/kg, and sample B-5N had a detectable cadmium concentration of 1.8 mg/kg.

Seven soil samples (B-3N [comp], B-4S [comp], B-5N [comp], B-9N [comp], B-10S [comp], B11W [comp], and B-12E [comp]) exceeded 10 times the STLC regulatory limit of 5 mg/L for chromium and were further analyzed using CA WET. Laboratory results indicated that STLC chromium concentrations were below detection limits, and the soil in these areas (Solano Street and Sacramento Avenue, Sacramento Avenue and Simon Terrace, Carrie Street, and Poplar Avenue) can be pre-classified as Non-hazardous (with respect to chromium). These samples did not exceed the ESLs for residential, commercial/industrial, and construction worker exposure limits (cancer risk).

Arsenic concentrations for all 13 composite samples exceeded all RWQCB ESLs, and these areas will need to be managed for worker safety during construction.

The Contractor(s) should prepare a project-specific Lead Compliance Plan (CCR Title 8, §1532.1, “Lead in Construction” standard) to minimize worker exposure to lead-containing soil for areas specified along Sacramento Avenue and across the street from Simon Terrace (B-6S). The plan should include protocols for environmental and personnel monitoring, requirements for personal protective equipment, and other health and safety protocols and procedures for the handling of lead-containing soil.

Recommendations from the results of the PSI are summarized below.

PSI Recommendations
Material Description Recommended Actions
ADL –
NonHazardous
Detectable concentrations of lead were
identified in all shallow soils at the PSI
study area. The soil is pre-classified as Nonhazardous.

Borings B-1 through B-5 and B-7 through B-13
did not have lead concentrations that exceeded
regulatory limits and did not exceed the RWQCB
ESLs.

The shallow soils are pre-classified as NonHazardous and can be reused on-site or disposed of at a Class III landfill, consistent with CCR Title
22 §66262.11 waste classification.

ADL- CA
Hazardous
Soil borings B-6S (1-2, 2-3, and composite)
had lead concentrations above the STLC
regulatory limit (5 mg/L) and is preclassified as California Hazardous.

The shallow soil from south of the intersection of
Simon Terrace and Sacramento Avenue are preclassified as California Hazardous.

Soil from these areas will need to be segregated in
stockpiles and disposed of at a Class I Landfill
(per Section 25117/25141 of the California Health
and Safety Code).

Arsenic
NonHazardous
Detectable arsenic concentrations within the
Project intersections are pre-classified as
Non-Hazardous. However, the arsenic
concentrations in soil exceeded all the
RWQCB ESLs.

Worker Safety Training will need to include
exposure to arsenic in soil (above all RWQCB
ESLs).

Dispose of excavated soils as Non-hazardous
waste at Class III landfill.

Chromium
NonHazardous
In addition, six composite samples B-3N, B4S, B-9N, B-10S, B-11W, and B-12E had detectable chromium concentrations below
all the RWQCB ESLs. However, the
chromium levels at these borings exceeded
10 times the Soluble Threshold Limit
Concentration (STLC) any regulatory limits
and are pre-classified as Non-hazardous.

The shallow soils can be pre-classified as nonhazardous and reused on-site or can be disposed of at a Class III landfill, consistent with CCR Title 22
§66262.11 waste classification.

Worker safety during construction will need to be
managed for Chromium.

1 INTRODUCTION
This report presents the results of the Preliminary Site Investigation (PSI) conducted by WRECO, on behalf of the City of West Sacramento for the HSIP Cycle 9 – Pedestrian and Median Improvements (Project) located at 14 intersections in the City of West Sacramento, Yolo County, California. The City of West Sacramento (City) Capital Projects and Transportation Department (CPTD) is planning on making minor pedestrian and median improvements at 14 intersections:

Lake Washington Boulevard and Southport Parkway, Lake Washington Boulevard and Westbridge Plaza Driveway, Jefferson Boulevard and 15th Street, Jefferson Boulevard at 11th Street, Sacramento Avenue and Sunset Avenue, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Reuter Drive at Andrews Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Quail Road to Columbus Road Shared Use Path, Columbus Road at Stonegate Elementary School and Shared Use Path, and La Jolla Street at Stonegate Elementary School. Eight intersections will involve soil disturbance activities and were identified as having potential impacts from historical uses and were the focus of the PSI. The California Department of Transportation (Caltrans) Local Assistance is implementing the safety improvements as part of the HSIP Federal Project No. HSIPL-047, 049, and 050. The Project Location Map is shown as Figure 1, and the Project Vicinity Map is shown as Figure 2.

1.1 Project Description
The Project is intended to reduce collisions and potential collisions by installing cost effective multimodal and pedestrian countermeasures to increase the safety of existing intersections and roadways. The City analyzed existing intersections and collision data with the purpose of identifying intersections that would benefit from improvements. It was found that the deficiencies and conflicts arose from difficult crossing conditions across arterial roads and included roadways with a history of pedestrian crossing-related crashes notably in areas with a higher probability of experiencing crashes due to the existing conditions. The top three factors leading to crashes were pedestrian violations (which means that crash occurred mainly due to pedestrians violating rightof-way), vehicles travelling at unsafe speeds (which means that the speed of the vehicle was not safe given the roadway/environment condition), and wrong way driving (which means that crash occurred due to driving on the wrong direction of the road. Accordingly, the proposed safety improvements are focused on increasing safety through the installation of cost-effective physical measures such as new and improved crosswalks, signalization, raised center medians, etc,. The installation of the new safety features are intended to reduce the overall severity and frequency of collisions between vehicles, bicyclist, and pedestrian within these identified key corridors.

The proposed improvements would occur within a total of 14 intersections listed in the Executive Summary above. This is known as the overall PSI study area. Also, as discussed above, based on preliminary analysis of publicly available hazardous materials databases and consultation with Caltrans, it was determined that eight of the 14 intersections would require additional analysis.

These 8 intersections known as the PSI Study Intersections include Jefferson Boulevard at 11th Street, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Columbus Road at Stonegate Elementary School and Shared Use Path, and La Jolla Street at Stonegate Elementary School.

Removals, Improvements, and Construction
The proposed project would require removal of existing hardscape including sidewalk and asphalt from the roadways, as well as small portions of the adjacent unpaved areas adjacent to the existing sidewalk. Hardscape materials proposed for removal would first be saw cut and then removed using machinery. Removed paving and asphalt would be hauled off-site by dump trucks. Materials would be hauled to a crushing facility to be broken down and recycled for other construction needs such as road base. Removals needed for the improvements would be to a depth of approximately 1-2 feet. Some removals and exaction would exceed this distance if needed to tie into or potentially make horizontal realignments of utilities. Full utility relocations are not anticipated.

After removal of the hardscape within the overall alignment, the proposed project would require minor excavation and earthwork needed to meet finish grades and install the water quality detention basins along the corridor. It is anticipated that grading would be limited to 1-2 feet. The project alignment would occur in areas that contain utilities including phone, electric, power poles, gas, cable, sewer, etc. The majority of utilities and utility boxes would be protected in place, but a few would be adjusted to grade. It is anticipated that most of the utilities, if needed, could be modified using vertical or horizontal alignment but it is not known if relocations would be needed.

As discussed above, the proposed project includes the installation of medians, new cross walks, stop limit lines and yield striping, installation of new RRFB boxes, ADA compliant curb ramps, and new sidewalks adjacent to some the improvement areas. The proposed project does not include any roadway improvements including additional lanes or alignment changes.

Construction of the proposed project would not require complete street closures during construction but may temporarily result in short-term single lane closure to facilitate construction and striping activities. Construction is anticipated to occur over a 12-month period. Construction is anticipated to begin in April of 2022 and be completed in 2022. The PSI was identified in the Preliminary Environmental Study (PES) signed on June 27, 2021 (Appendix A).

2 PROJECT AREA SETTING
The PSI study area is located at the intersections of Jefferson Boulevard at 11th Street, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Columbus Road at Stonegate Elementary School and Shared Use Path, and La Jolla Street at Stonegate Elementary School. The adjacent uses to the intersections are comprised of residential and commercial structures. The roadways where the PSI was conducted are heavily travelled and have a high incidence of collisions.

2.1 Physical Setting

2.1.1 Topography
The average elevation of the PSI study area is relatively flat at approximately 17 feet (ft) above mean sea level (AMSL) as described in the Initial Study/Mitigated Negative Declaration (LSA, 2019). The United States Geological Survey (USGS), West Sacramento, California (7.5-minute) Topographic Quadrangle map was reviewed and indicated that the intersections are moderately sloped to the east towards the Sacramento River (USGS, 2015).

2.1.2 Regional Geology
The PSI study area is in the Great Valley geomorphic province of California, and consists of two valleys, the Sacramento Valley to the north and the San Joaquin Valley to the south. Over the past several thousand years, flooding, erosion and deposition, and movement of the river have left behind a suite of alluvial deposits consisting of sand, silt, clay, and gravel (DWR, 2008). These thick sequences of sediments are derived from marine and non-marine sources. Up to 25,000 ft of sediment is present in the south-central portion of the Great Valley (Norris and Webb, 1990). The geologic formations with that comprise the Great Valley sequence vary from Quaternary to Jurassic aged deposits, with the older deposits derived primarily from marine sources and the younger deposits derived primarily from continental sources. The Regional Geology Map is shown as Figure 7.

2.1.3 Local Geology and Soils
The thick sequences of the older and coarser grained alluvium of the former river channel (and related channel deposits) comprises the underlying, deeper strata. These deeper Quaternary and latest Pleistocene deposits (map unit Qal; Helley and Harwood, 1985) of the river are more conductive to groundwater flow and represent ancestral channel and meandering floodplain sediments deposited sub-parallel to the present-day river direction. The distribution of surficial deposits does not necessarily coincide with those in the subsurface because of changes in river position over time (DWR, 2008). The Quaternary stream channel sediments (map unit Qsc; Helley and Harwood, 1985) are deposits of the open, active channel, without permanent vegetation, and are on the left and right banks of the active river channel. The deposits on the left descending bank of the site are point bar and meander scroll deposits. Because the stream channel deposits represent the active depositional-erosional surface, the morphology within the deposits is constantly changing (DWR, 2008).

2.1.4 Naturally Occurring Asbestos
Naturally Occurring Asbestos (NOA) can occur in serpentine rock and in its parent material, ultramafic rock. These rock types are abundant in the Sierra Nevada foothills. NOA has not been identified in Yolo County with ultramafic rocks have been generally mapped along the eastern side of the Sierra Nevada foothills. The most common forms of naturally occurring fibrous minerals with NOA are chrysotile, actinolite, and tremolite. A review of the “General Location Guide for Ultramafic Rocks in California – Areas Likely to Contain Naturally Occurring Asbestos” (CGS, 2000) indicated that NOA has not been mapped in the vicinity of the PSI study area.

2.1.5 Groundwater Hydrology
The PSI study area is in the Sacramento Valley Basin, Yolo Subbasin (5-021.67), as defined by the California Department of Water Resources (DWR, 2006) and shown in Figure 8. The Sacramento River Basin encompasses approximately 27,000 square miles and is bounded by the Sierra Nevada to the east, the Coast Ranges to the west, the Cascade Range and Trinity Mountains to the north, and the Sacramento – San Joaquin Delta (Delta) to the southeast. The Sacramento River Basin is the largest river basin in California, capturing, on average, approximately 22 million acre-feet of annual precipitation. The Sacramento River is approximately 327 miles long, and its major tributaries are the Pit River and McCloud River, which join the Sacramento River from the north, and the Feather and American Rivers, which are tributaries from the east. The Sacramento Valley portion of the basin contains the largest population, concentrated in the cities of Sacramento, West Sacramento, Chico, Red Bluff, and Redding. The river is regulated by Shasta Dam and several dams on the major tributaries, including Oroville Dam on the Feather River and Folsom Dam on the American River, which provide power generation, flood control, water supply, recreation, fisheries, and wildlife management.

The Yolo Valley Subbasin is located within the southern portion of the Sacramento Valley Basin.

As described by DWR, the subbasin is bounded on the north by the Yolo County line, except where it is broken by the Capay Hills north of Napa Valley. The Yolo Subbasin consists of unconsolidated to semi-consolidated Quaternary and Tertiary sedimentary deposits, including Quaternary alluvium (Q), Pleistocene arkosic alluvium of the Modesto-Riverbank Formations (Qmr), and Pliocene sand, silt, and volcanic rocks of the Tehama Formation (Pt).

Based on a review of GeoTracker groundwater monitoring data near the PSI study area, depth to shallow groundwater ranges from 22.69 to 42.34 ft below ground surface (bgs), as measured by GEI Consultants in 2015. Groundwater flow direction generally ranges based on boring location due to shallow aquifers in the area and slight slope inland towards the Sacramento River (GEI, 2015).

2.1.6 Surface Water Hydrology
The City of West Sacramento is located at the meeting of the Sacramento and American rivers within the Sacramento Valley River Basin (Figure 9). The American River watershed climate is temperate and is characterized by wet winters and dry summers; 95% of the annual precipitation occurs between November and April as both rain and snow at higher elevations as reported in the Environmental Impact Report by ESA (2013). Flows in the Sacramento and American rivers are Attachment 3

influenced by the volume of surface runoff within the respective watersheds, rainfall, the operation of upstream dams, Sierra Nevada spring snowmelt, local groundwater, and tidal action, which extends to the upper extent of the Delta in the Sacramento River at the I Street Bridge, just downstream of the confluence with the American River (ESA, 2013).

Numerous additional tributary streams and creeks flow from the east and west as bounded by the Sacramento River on its northern and eastern borders, and the Sacramento River Deep Water Channel and Yolo Bypass on its western border. The City of West Sacramento is surrounded by levees, and to the west of the City is an undeveloped riparian area consisting of permeable surfaces.

3 PRELIMINARY SITE INVESTIGATION

3.1 Soil Sampling Methods and Procedures
On August 11, 2021, WRECO conducted a PSI that consisted of collecting shallow soil samples from 13 borings the PSI study area that includes the eight intersections proposed for pedestrian and median improvements that will incur soil disturbance. The PSI was performed within the landscaped or unpaved areas located at the intersections of Jefferson Boulevard at 11th Street, Sacramento Avenue at Solano Street, Sacramento Avenue at Simon Terrace, C Street at 6th Street, Carrie Street at Bryte Park, Poplar Avenue at Westfield Village Elementary School, Columbus Road at Stonegate Elementary School and Shared Use Path, and LaJolla Street at Stonegate Elementary School. The PSI Study was performed to verify the presence/absence of COCs from historical use, evaluate the options for soil disposal or reuse, and to provide guidance for waste management and worker safety during construction.

Prior to field work being performed, the sample locations were marked in white paint, and USA North 811 was contacted to mark utilities near the boring locations. An encroachment permit was not required to work within the City’s right-of-way in West Sacramento. The shallow soil investigation was performed using direct push technology (DPT) methods to take continuous core soil samples at specific locations as shown on Figure 10, Figure 11, and Figure 12. DPT uses a hydraulically operated percussion hammer along with vehicle weight to advance the sampling barrel with an acetate liner used to contain the soil sample.

Environmental Control Associates of Sacramento, California used a Geoprobe® 54LT Track Rig to advance 13 soil borings (B-1 through B-13) at eight of the Project intersections using a 5-ft continuous coring sampler with an acetate liner. Because the diameter of the DPT is only 2.25 inches, minimal drill cuttings were generated, thereby lowering the amount of investigation derived waste produced. Soil samples were contained in the 5-ft acetate liner, and the liner was cut at specific intervals of 0-1, 1-2, and 2-3 ft bgs, capped at each end with a Teflon sheet and plastic lid, labeled, and placed into an ice chest with ice. The chain of custody was completed in the field and relinquished to laboratory staff upon delivery to California Laboratory Services (CLS) Laboratory in Rancho Cordova, California.

Soil encountered during sampling consisted of sandy clay. The borings were backfilled with grout and capped with native soil. All the soil samples collected were analyzed for lead using EPA Method 6010B and pH using EPA Method 9045C. Samples from each boring were homogenized in the laboratory and analyzed for additional COCs that included pesticides (OPP and OCP) (EPA Methods 8141 and 8081), Total Petroleum Hydrocarbons (TPH) as gasoline, diesel, and motor oil (EPA Method 8015), VOCs (EPA Method 8260), PCBs (EPA Method 8082), SVOCs (EPA Method 8270), PAHs (EPA Method 8310), and California Administrative Metals (CAM) 17 Metals (EPA Method 6000/7000). Soil boring sampling details are summarized in Table 1 and locations in Figure 10, Figure 11, and Figure 12.

3.2 Analytical Results
Thirty-nine (39) soil samples (with sampling depths of 0-1 ft, 1-2 ft, and 2-3 ft), collected from 13 borings, were analyzed for total lead and pH. Detectable lead concentrations for sampling depth 0-1 ft ranged from 2.5 to 41 milligrams per kilogram (mg/kg); 1-2 ft ranged from 2.8 to 130 mg/kg; and 2-3 ft ranged from 2.7 to 150 mg/L. The pH of the 39 soil samples analyzed ranged from 5.32 to 8.38, which is within the threshold (greater than 2 and less than 12.5) for state waste criteria reuse or disposal to a Class III composite-lined landfill (RCDWM, 2019).

Four soil samples (B-5N [comp], B-6S [comp], B-6S [1-2], and B-6S [2-3]) had lead concentrations exceeding 10 times the Soluble Threshold Limit Concentration (STLC) regulatory limit of 5 milligrams per liter (mg/L) and were further analyzed using California Waste Extraction Test (CA WET). Laboratory results indicated that STLC lead concentrations ranged from 2.2 to

7.9 mg/L, and samples B-6S (comp) (5.2 mg/L), B-6S (1-2) (7.9 mg/L), and B-6S (2-3) (7.3 mg/L) exceeded the STLC regulatory limit and were further analyzed using the toxicity characteristic leaching procedure (TCLP). Laboratory results indicated the TCLP concentrations were below detection limits for all samples from B-6S, and the soil can be pre-classified as California hazardous (with respect to lead). Detectable lead concentrations exceeded the Regional Water Quality Control Board (RWQCB) Environmental Screening Levels (ESL) for residential, but not for construction worker or commercial/industrial exposure. Analytical results for the lead and pH soil screening are summarized in Table 2.

Samples from each boring were homogenized in the laboratory and analyzed for additional COCs that included pesticides (OPP and OCP) (EPA Methods 8141 and 8081), Total Petroleum Hydrocarbons (TPH) as gasoline and diesel (full range) (EPA Method 8015), VOCs (EPA Method 8260), PCBs (EPA Method 8082), SVOCs (EPA Method 8270), PAHs (EPA Method 8310), and CAM 17 Metals (EPA Method 6000/7000). All concentrations of metals, pesticides (OCP/OPP), PAHs, TPH (as diesel, hydraulic, kerosene, mineral oil, and gasoline), VOCs, and PCBs were below detection limits. Concentrations of TPH as motor oil ranged from ND to 420 mg/kg (B-6S).

Acetone was detected in sample B-11W (comp) at a concentration of 250 ug/kg.

Three samples, B-11W (comp), B-12E (comp), and B-13W (comp), had detectable pesticide concentrations of chlordane (55 ug/kg), DDE/DDT (3.5/3.4 ug/kg), and DDE/DDT and dieldrin (13/6 ug/kg and 11 ug/kg), respectively, that exceeded 10 times the STLC and were further analyzed using CA WET. Laboratory results indicated that STLC concentrations were all below detection limits, and the soil in these areas (Poplar Avenue, Columbus Road, and La Jolla Street) is pre-classified as Non-hazardous (with respect to these pesticides). Detectable concentrations did not exceed the RWQCB ESLs for residential, construction worker, and commercial/industrial exposure.

Thirteen composite samples had detectable CAM 17 Metals concentrations of arsenic that ranged from 2.0 to 6.3 mg/kg; barium ranged from 56 to 120 mg/kg; chromium ranged from 31 to 66 mg/kg; cobalt ranged from 8.2 to 48 mg/kg; copper ranged from 7.3 to 38 mg/kg; lead ranged from

5.8 to 110 mg/kg; nickel ranged from 31 to 80 mg/kg; silver ranged from 1.1 to 2.8 mg/kg; vanadium ranged from 30 to 63 mg/kg; and zinc ranged from 30 to 130 mg/kg. Sample B-6S had Attachment 3

a detectable mercury concentration of 0.14 mg/kg, and sample B-5N had a detectable cadmium concentration of 1.8 mg/kg.

Seven soil samples (B-3N (comp), B-4S (comp), B-5N (comp), B-9N (comp), B-10S (comp), B11W (comp), and B-12E (comp)) exceeded 10 times the STLC regulatory limit of 5 mg/L for chromium and were further analyzed using CA WET. Laboratory results indicated that STLC chromium concentrations were below detection limits, and the soil in these areas (Solano Street/Sacramento Avenue, Sacramento Avenue/Simon Terrace, Carrie Street, and Poplar Avenue) can be pre-classified as Non-hazardous (with respect to chromium). These samples did not exceed the ESLs for residential, commercial/industrial, and construction worker exposure limits (cancer risk). Therefore, the soil in the areas of the 13 composite samples at the eight intersections need to be managed for worker safety during construction for chromium.

Arsenic concentrations for all 13 composite samples exceeded all RWQCB ESLs, and these areas will need to be managed for worker safety during construction.

The analytical results for the ADL samples are summarized in Table 2, and analytical results for the composite samples are summarized in Table 3. Concentrations of lead and chromium exceedances in soil are shown in Figure 13 to Figure 17. Laboratory Reports are provided in Appendix B.

3.3 Hazardous Waste Determination Criteria
Due to the historical use of lead in gasoline formulations, lead contamination is common in surface soils along roadways. ADL-impacted soils are regulated at both the federal and state levels, because they can be classified as federal hazardous waste, or they are subject to state regulations when not classified as federal hazardous waste, and they may represent a health risk to construction workers that will be excavating shallow soil for the Project intersection improvements.

Regulatory criteria to classify a waste as “California Hazardous” for handling and disposal purposes are contained in the California Code of Regulations (CCR), Title 22, Division 4.5, Chapter 11, Article 3, § 66261.24.

For solid wastes (soil) containing lead, the waste is classified as California Hazardous when:
• Total lead concentrations equal to or exceeding 1,000 mg/kg, the TTLC, are classified as Hazardous waste.
• Soluble lead concentrations (assessed using CA WET procedures) equal to or exceeding

5.0 mg/L, the STLC, are classified as California Hazardous under California law. • California hazardous materials must be transported under a hazardous waste manifest and disposed of at an appropriately permitted facility.
• Wastes with lead concentrations less than both the TTLC and the STLC are NonHazardous waste and may be disposed of at a Class III facility, provided that site-specific disposal facility requirements are satisfied.

A waste may have the potential of exceeding the STLC when the waste’s total metal content (as TTLC) is greater than or equal to 10 times the respective STLC value, since the WET uses a 1:10 dilution ratio. Hence, when a total metal is detected at a concentration greater than or equal to 10 times the respective STLC, and assuming that 100% of the total metals are soluble, soluble metal analysis is required.

Criteria to classify a waste as “Resource, Conservation, and Recovery Act (RCRA) Hazardous” are contained in Chapter 40 of the Code of Federal Regulations (40 CFR), § 261.

The above regulatory criteria are based on chemical concentrations. Wastes may also be classified as hazardous based on other criteria such as ignitability and corrosivity; however, for the purposes of this investigation, toxicity (i.e., representative lead concentrations) is the primary factor considered for waste classification since waste generated during the construction activities would not likely warrant testing for ignitability or corrosivity. Waste that is classified as either Californiahazardous or RCRA-hazardous requires management as a hazardous waste.

3.4 Results and Findings
The PSI was performed to verify the presence/absence of potential COCs, to evaluate the available options for soil disposal or reuse during construction, and to provide specific guidance for waste management and worker safety during construction.

• On August 11, 2021, 13 soil borings were sampled from DPT borings (B-1 to B-13) at depth intervals of 0-1, 1-2, 2-3 ft bgs (39 soil samples collected). • All 39 soil samples collected were analyzed for lead and pH. Detectable lead concentrations for sampling depth 0-1 ft ranged from 2.5 to 41 mg/kg; 1-2 ft ranged from

2.8 to 130 mg/kg; and 2-3 ft ranged from 2.7 to 150 mg/kg. The pH ranged from 5.32 to

8.38, which is within the threshold (greater than 2 and less than 12.5) for state waste criteria reuse or disposal to a Class III composite-lined landfill. • Detectable lead concentrations at B-5N (Comp), B-6S (1-2), (2-3), and B-6S comp exceeded STLC regulatory limits and were further analyzed for CA WET. • Laboratory results indicated that the STLC lead concentrations ranged from 2.2 to 7.9 mg/L, and samples B-6S Comp (5.2 mg/L), B-6S (1-2) (7.9 mg/L), and B-6S (2-3) (7.3 mg/L) exceeded the STLC regulatory limit and were further analyzed using the toxicity characteristic leaching procedure (TCLP).
• Laboratory results indicated the TCLP concentrations were below detection limits for all samples from B-6S, and the soil can be pre-classified as California hazardous (with respect to lead).
• Detectable lead concentrations exceeded the ESLs for residential, but not for construction worker or commercial/industrial exposure.
• Thirteen composite samples had detectable CAM 17 Metals concentrations of arsenic that ranged from 2.0 to 6.3 mg/kg; barium ranged from 56 to 120 mg/kg; chromium ranged from 31 to 66 mg/kg; cobalt ranged from 8.2 to 48 mg/kg; copper ranged from 7.3 to 38 mg/kg; lead ranged from 5.8 to 110 mg/kg; nickel ranged from 31 to 80 mg/kg; silver ranged from 1.1 to 2.8 mg/kg; vanadium ranged from 30 to 63 mg/kg; and zinc ranged from 30 to 130 mg/kg. Sample B-6S had a detectable mercury concentration of 0.14 mg/kg, and sample B-5N had a detectable cadmium concentration of 1.8 mg/kg. • Seven soil samples, B-3N (comp), B-4S (comp), B-5N (comp), B-9N (comp), B-10S (comp), B-11W (comp), and B-12E (comp) exceeded 10 times the STLC regulatory limit of 5 mg/L for chromium and were further analyzed using CA WET. • Laboratory results indicated that STLC chromium concentrations were below detection limits, and the soil in these areas (Solano Street and Sacramento Avenue, Sacramento Avenue and Simon Terrace, Carrie Street, and Poplar Avenue) can be pre-classified as Non-hazardous (with respect to chromium). These samples did not exceed the ESLs for residential, commercial/industrial, and construction worker exposure limits (cancer risk). • Arsenic concentrations exceeded all ESLs; Soil in the intersections sampled should be managed for worker safety during construction for lead, chromium, and arsenic. • Three composite samples had detectable OCP concentrations of 4,4-DDE that ranged from

0.0035 to 0.013 mg/kg, 4,4-DDT that ranged from 0.0034 to 0.06 mg/kg, dieldrin was detected in two borings (B-12E and B-13W) ranging from 0.0055 to 0.0011 mg/kg, and chlordane was detected in one boring (B-11W) at 0.055 mg/kg. • All concentrations of metals, pesticides (OCP/OPP), PAHs, TPH (as diesel, hydraulic, kerosene, mineral oil, and gasoline), VOCs, and PCBs were below detection limits.

Concentrations of TPH as motor oil ranged from ND to 420 mg/kg (B-6S). Acetone was detected in sample B-11W (comp) at a concentration of 250 ug/kg.

4 CONCLUSIONS AND RECOMMENDATIONS
WRECO analyzed soil for COCs and screened the results against RWQCB ESLs that take into consideration risks of direct and indirect exposure to construction workers (as well as residential and commercial/industrial uses). Under most circumstances, the presence of a chemical in soil, soil gas, or groundwater at concentrations below the corresponding ESL can be assumed to not pose a significant threat to human health, water resources, or the environment.

Laboratory results indicate that shallow soil may contain levels of arsenic, chromium, and lead.

Worker safety measures should follow Cal/OSHA regulations to limit exposure and hazards to construction workers during soil disturbance for the roadway improvements. The ESLs are criteria that are used for determining human exposure limits and will be used for worker safety requirements during Project construction.

4.1.1 Arsenic in Soil
The PSI study area is contained within a former agricultural region of Yolo County, and the use of phosphate and micronutrient fertilizers contain potentially harmful trace elements such as arsenic, chromium, and lead. Arsenic occurs naturally in soil and minerals and may enter the air, water, and land from wind-blown dust and may get into water from runoff and leaching. Sample results indicated that arsenic concentrations ranged from 2 to 6.3 mg/kg, which exceed all RWQCB ESLs.

Background arsenic levels in California tend to be higher than the RWQCB ESLs used for evaluation of a soil’s hazardous classification, and various studies have shown much higher levels in soil. The United States Geological Survey (USGS, 1984) provided a regional estimate for arsenic of 18 mg/kg and cobalt of 23 mg/kg (both upper estimates). The Lawrence Berkeley National Laboratory (LBNL, 2009) provided upper estimates of background levels (based on statistical analysis) of arsenic and cobalt. The LBNL study indicated concentrations of arsenic and cobalt at 24 mg/kg and 25 mg/kg, respectively. Due to the high capacity of clay and organic matter to adsorb metallic ions, arsenic concentrations tend to be highest in soils that contain high percentages of clay and organic material (e.g., clay and clay loamy soils, organic light [or rich] soils) (NAVFAC, 2002). Therefore, it is expected that finer-grained depositional environments within the Bay Area would likely have higher natural concentrations of arsenic relative to sandy or gravelly soils. Soils containing arsenic in the PSI study area needs to be managed for worker safety during construction.

4.1.2 Chromium in Soil
Six samples, from borings B-3N, B-4S, B-9N, B-10S, B-11W, and B-12E, had chromium concentrations that exceeded 10 times the STLC and were analyzed using CA WET, which yielded non-detectable concentrations below the STLC regulatory limit. Therefore, the soil is preclassified as Non-hazardous. Total chromium concentrations in U.S. soils range from 1 to 2,000 mg/kg, with a mean of 37.0 mg/kg (USGS, 1984). Human exposure to chromium occurs from both natural and anthropogenic sources. Natural chromium sources come from the Earth's crust with continental dust present in the environment, primarily as chromium (III). Chromium is released into the atmosphere by anthropogenic sources, including industrial, commercial, and residential fuel combustion, via the combustion of natural gas, oil, and coal, and metal industries including Attachment 3

chrome plating and steel in the hexavalent form, chromium (VI). Chromium (VI) in soil can be rapidly reduced to chromium (III) by organic matter. Soils containing chromium in the PSI study area needs to be managed for worker safety during construction.

4.1.3 Lead in Soil
All the lead concentrations were below the commercial/industrial RWQCB ESL of 320 mg/kg, however, concentrations in some borings exceeded the residential ESLs (80 mg/kg) however, soil containing lead is still below the TTLC (1,000 mg/kg) and is considered Non-hazardous.

Detectable lead concentrations exceeded the ESLs for residential. But not for construction worker, or commercial/industrial exposure. The soil in these areas may be pre-classified as CA Hazardous.

4.1.4 Organochlorine Pesticides in Soil
Low concentrations of DDE, DDT, Dieldrin, and chlordane, were found in the borings near Columbus Road and La Jolla Street. Pesticides are a group of chemicals used for the destruction of insects, weeds, fungi, bacteria, etc. They are generally called insecticides, fungicides, bactericides, herbicides, or rodenticides. Most of the pesticides have the ability to destroy a wide variety of pests or weeds, but some are developed against specific pests or pathogens.

Organochlorine pesticides (chlordane, dieldrin, DDT, DDD, and DDE) are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in agriculture and mosquito control. Organochlorine pesticides are synthetic pesticides that accumulate in the environment and may be a significant source of contamination of the air, water, and soil. They are very persistent and move long distances in surface runoff or groundwater. These compounds are known for their high toxicity, slow degradation and bioaccumulation. Agricultural use of pesticides includes heavy metals such as iron, lead, sulphur, arsenic, mercury, zinc, and tin. Organochlorine pesticides can enter the environment through pesticide applications, polluted wastes discarded into landfills, and discharges from industrial units that synthesize these chemicals. They are volatile and stable; some can adhere to the soil and air, thus increasing the chances of high persistence in the environment, and are identified as agents of chronic exposure to animals and humans. Long-term exposure to organochlorine pesticides may damage the liver, kidney, central nervous system, thyroid, and bladder. Many of these pesticides have been linked to elevated rates of liver or kidney cancer in animals. There is some evidence indicating that organochlorine pesticides may also cause cancer in humans (Jayaraj, R., 2017).

Dieldrin is the common name of a persistent, non-systemic organochlorine insecticide used for control of public health insect pests, termites, and locusts. Another source of dieldrin in the environment other than from direct use of dieldrin stems from the quick transformation of aldrin, also an organochlorine pesticide, to dieldrin. Both dieldrin and aldrin usage peaked in the mid1960s and declined in the early 1970s, when all dieldrin products were banned (including aldrin) on March 18, 1971. Endrin is the common name of a wide-ranging organochlorine insecticide/rodenticide. It has been used with a variety of crops including cotton, tobacco, sugar cane, rice, and ornamentals. One of its major uses in the U.S. was for control of Lepidoptera larvae on cotton. During the 1970s and early 1980s, its use was increasingly restricted until it was banned on October 10, 1984.

4.2.1 Project Specific Concerns
Arsenic - Arsenic is a naturally occurring element that is often detected in soil at concentrations that equal or exceed regulatory screening levels for both residential and industrial soil. The DTSC is aware of the ubiquitous nature of arsenic in California soil and generally does not consider concentrations of arsenic within the range of naturally occurring background levels to be a concern.

Soil cleanup guidelines for arsenic vary widely in the U.S., ranging from 0.039 to 40 mg/ kg. The PSI study area had arsenic values ranging from 2.0 mg/kg to 6.0 mg/kg. The arsenic concentrations were below the STLC regulatory limit, and the soil is pre-classified as Non-hazardous for reuse at the Project site or disposal at a Class III Landfill, consistent with CCR Title 22 §66262.11 waste classification in regard to the arsenic levels. Arsenic concentrations in soil will need to be managed during construction for worker safety.

Chromium - Chromium is a naturally occurring element in rocks, animals, plants, soil, and volcanic dust and gases. Chromium occurs in primarily in two valence states, trivalent chromium (Chromium III) and hexavalent chromium (Chromium VI). Exposure may occur from natural or industrial sources of chromium. Chromium III is recognized as a trace element that is essential to both humans and animals.

Chromium VI compounds are toxic and inhaled Chromium VI is recognized as a human carcinogen. The body can detoxify some amount of Chromium VI to Chromium III. Chromium compounds in soil can be inhaled and result in airway irritation, airway obstruction, and lung, nasal, or sinus cancer. Chromium concentrations were below the STLC regulatory limit (CA WET analysis) and the soil is pre-classified as Non-hazardous with respect to Chromium for reuse at the Project site or disposal at a Class III Landfill. Chromium concentrations in soil will need to be managed during construction for worker safety.

Aerially deposited lead - ADL is typically found within the top 3 ft of soil in unpaved areas along roadways. Lead concentrations were below the STLC regulatory limit and the soil is pre-classified as Non-hazardous for reuse at the Project site or disposal at a Class III Landfill. Lead concentrations in shallow soil will need to be managed during construction for worker safety. • Caltrans Standard Special Provisions (SSP) 7-1.02K(6)(j)(iii) (DOCX) (10/19/2018) - Earth Material Containing Lead - Requires a lead compliance plan for soil disturbance when lead concentrations are non-hazardous.
• Caltrans Standard Specification 14-11.08 Regulated Material Containing ADL (2018). • Caltrans Standard Specification 14-11.09 Minimal Disturbance of Regulated Material Containing ADL (2018).

4.3 Waste Classification and Disposal Options
Waste classification and disposal for Project sites that generate soil containing COCs that exceed regulatory requirements for soil reuse, should follow the decision options shown in Figure 18.

personnel monitoring, requirements for personal protective equipment, and other health and safety protocols and procedures for the handling of lead-containing soil.

4.4 PSI Recommendations
Based on the results of the PSI, WRECO has summarized the following recommendations in the table below.

RECOMMENDATIONS SUMMARY
Material Description Recommended Actions
ADL –
Non-Hazardous
Detectable concentrations of
lead were identified in all
shallow soils at the PSI study
area. The soil is pre-classified
as Non-hazardous.

Borings B-1 through B-5 and B-7 through B-13 did not
have lead concentrations that exceeded regulatory limits and did not exceed the RWQCB ESLs.

The shallow soils are pre-classified as Non-Hazardous and can be reused on-site or disposed of at a Class III landfill, consistent with CCR Title 22 §66262.11 waste
classification.

ADL- CA
Hazardous
Soil borings B-6S (1-2, 2-3, and
composite) had lead
concentrations above the STLC
regulatory limit (5 mg/L) and is
pre-classified as California
Hazardous.

Soil from boring B-6S in samples B6S (Comp) (5.2 mg/L), B6S (1-2) (7.9 mg/L), and B6S (2-3) (7.3 mg/L) exceeded the STLC regulatory limit, south of the intersection of Simon Terrace and Sacramento Avenue, and can be preclassified as California Hazardous.

Soil from these areas will need to be segregated in
stockpiles and disposed of at a Class I Landfill (per Section 25117/25141 of the California Health and Safety Code).

Arsenic
Non-Hazardous
Detectable arsenic
concentrations within the PSI
study intersections are preclassified as Non-Hazardous.

However, the arsenic
concentrations in soil exceeded
all the RWQCB ESLs.

Worker Safety Training will need to include exposure to arsenic in soil (above all RWQCB ESLs).

Dispose of excavated soils as Non-hazardous waste at
Class III landfill.

Chromium
Non-Hazardous
In addition, six composite
samples B-3N, B-4S, B-9N, B10S, B-11W, and B-12E had
detectable chromium
concentrations below all the
RWQCB ESLs. However, the
chromium levels at these
borings exceeded 10 times the
Soluble Threshold Limit
Concentration (STLC) any
regulatory limits and are preclassified as Non-hazardous.

The shallow soils can be pre-classified as non-hazardous and reused on-site or can be disposed of at a Class III landfill, consistent with CCR Title 22 §66262.11 waste
classification.

Worker safety during construction will need to be managed for Chromium.

5 LIMITATIONS
The scope of a PSI includes verification of potential COCs by collecting and analyzing shallow soil samples from areas that will incur soil disturbance. The potential exists for unknown contamination to be revealed during construction. The PSI study area located in the City of West Sacramento, California, was performed in general accordance with the ASTM E1903-11 Standard.

All readily available materials pertaining to the PSI study area were reviewed prior to performing the investigation and used to help prepare this report. This assessment is not a full-scale environmental site investigation to prove that the PSI study area is environmentally devoid of hazardous or toxic materials. Samples were collected in specific locations for the intersection improvements to determine baseline concentrations of potential COCs.

This PSI consists of professional opinions and recommendations made in accordance with generally accepted environmental principles and practices. The conclusions are based upon an evaluation of the information gathered and analytical data from the soil samples collected from the PSI study area. This PSI does not provide any implied or expressed guarantees regarding the characteristics or environmental conditions at the PSI study area.

The findings and conclusions in this report are based solely on the limited scope of the PSI, and it is not warranted that the PSI study area does not include hazardous materials or petroleum hydrocarbon releases in areas that were not tested or discussed in this report.

This PSI is not intended to identify ALL hazards or unsafe conditions, or to imply that others do not exist. This soil sampling and testing investigation was planned and implemented based on a mutually agreed scope of work and WRECO’s experience in performing this type of assessment.

WRECO has performed this investigation in a professional manner using the degree of skill and care exercised for similar projects under similar conditions, by reputable and competent environmental consultants. WRECO shall not be responsible for conditions or consequences arising from relevant facts that were not identified or disclosed at the time that this investigation was conducted.

WRECO further states that no warranties, expressed or implied are made regarding the quality, fitness, or results to be achieved because of this report or impacted by information not properly disclosed to WRECO at the time of this report. In addition, no responsibility is assumed for the control or correction of conditions or practices existing at the at the PSI study area.

Verification of material quantities is the responsibility of the contractor that will be performing construction activities at the PSI study area. It is the responsibility of the construction Contractor to determine the appropriate waste management and disposal actions for shallow soil within the PSI study area. Hazardous materials must be handled in strict accordance with the various federal, state, and local regulations. Failure to abide by these regulations can result in penalties to both the contractor as well as the Client.

(May Also Include Continuation of Detailed Project Description) Project Location
The project area is entirely within the City of West Sacramento (City)within existing roadways and intersections. The City is located in Yolo County, California. The proposed project would make minor pedestrian and median improvements to 14 roadways and intersections within the City. The intersections include Intersection 1) Lake Washington Boulevard and Southport Parkway; 2) Intersection of Lake Washington Boulevard and Westbridge Plaza Driveway, Intersection 3) Jefferson Boulevard and 15th Street; Intersection 4) Jefferson Boulevard at 11th Street , Intersection 5) Sacramento Avenue and Sunset Avenue; Intersection 6) Sacramento Avenue at Solano Street, Intersection 7) Sacramento Avenue at Simon Terrace, Intersection 8) C Street at 6th Street; Intersection 9) Reuter Drive at Andrew’s Street; Intersection 10) Carrie Street at Bryte Park, Intersection 11 Poplar Avenue at Westfield Village Elementary School; Intersection 12) Quail Road to Columbus Road Shared Use Path, Intersection 13) Columbus Road at Stonegate Elementary School and Shared Use Path, and Intersection 14) La Jolla Street at Stonegate Elementary School.

Purpose and Need
The purpose of the project is to reduce collisions and potential collisions by installing cost effective multimodal and pedestrian countermeasures to increase the safety of existing intersections and roadways. The City analyzed existing intersections and collision data with the purpose to identify intersections that would benefit from improvements. The analysis focused on the following initial objectives:
• Identify a list of traffic safety projects to implement based on the data-driven collision analysis, feasibility, cost, and schedule constraints while maintaining a benefit cost-ratio that is competitive for Highway Safety Improvements Program (HSIP) Cycle 9 grant applications;
• Identify project which will improve safety of vehicles, bicyclists and pedestrian on local facilities throughout the City;
• Prioritize key corridors where safety can be improved through cost-effective countermeasures; and • Secure funding to implement safety improvements through the HISP funded by the Federal Highway Administration (FHWA).

To meet the objections, the City used and analyzed information in the data sets for each reported collision and developed a strategy including physical improvements that would improve safety. Information analyzed included thedate, time, location, traffic control, weather, severity of the collision, primary collision factor, lighting, and California Highway Patrol (CHP) notes.

The findings of the analysis were used to develop an initial set of identified projectsthat were further refined by the Citystaff.

Projects were filtered by cost, feasibility, constraints, competitiveness of Benefit Cost Ratio (BCR), field observations, and potential safety benefits. West Capitol Boulevard was identified as the highest priority but had already received funding and was ineligible. This left the City with a final list of projects that were identified to be competitive and implementable through the HSIP Cycle 9 grant process. These work efforts lead to the proposal to implement the14 projects discussed in this document and help meet the overall purpose of improving roadway safety and enhancing pedestrian and multimodal-travel opportunities.

As discussed above, one of the purposes of the proposed project is to increase the safety of intersections and travel ways. All proposed improvements were identified based on a combination of intersections deficiencies. Another purpose of the project is to remedy these deficiencies by resolving conflicts and difficult crossing conditions across arterial roads, roadways with a history of pedestrian crossing-related crashes, and areas with a higher probability of experiencing crashes due to present conditions. As discussed, while some ofthe locations did not have a history of crashes, some of the improvements are proposed to construct improvements and facilitate safer crossings of arterials that have long distances to the nearest signalized crossing; heavier traffic from trip generators; and have the potential for significant pedestrian related crashes.

The evaluation ofthe crash records for the city’s roadway network proved that the needed for the intersection improvements.

The crash records revealed there were 23 fatal crashes and 42 severe injury crashes in the City. This respectively made up

0.67% and 1.23% of all crashes. While this was an overall low percentage of total crashes, the significance of death and severe injury accidents define and justify the need to improve safety. It was also noted that pedestrian crashes made up 30.7% of the total equivalent property damage only (EPDO)score, and bicycle crashes comprised 12.1%. Ranked by the EPDO score, the Attachment 3

top three factors leading to crashes were pedestrian violations (which means that crash occurred mainly due to pedestrians violating right-of-way), vehicles travelling at unsafe speeds (which means that the speed of the vehicle was not sa fe given the roadway/environment condition), and wrong way driving (which means that crash occurred due to driving on the wrong direction of the road).

To satisfy the need of reducing these causative factors, the proposed project includes numerous pedestrian improvements including new and improved crosswalks, signalization, raised center medians, etc.. The project is needed to reduce overall collisions, and reduce the overall severity and frequency of collisions at the identified intersection. Table 1 – Viable Project List is taken from the West Sacramento Systemic Safety Analysis Final Report (WSSSAR), which summarized basic improvements at the project intersections and roadways that are needed for the purpose of increasing safety of the transportation system.

Project Description
Overview
Consistent with efforts of the City to improve safety on some of its major arterials, the proposed project would enhance the multi-modal transportation network by installing redesigned pedestrian and bicycle crossings of both major and local neighborhood streets, and also by reducing some currently allowable vehicular travel and turning movements. The improvements are based on a review of city-wide crash data that included unsignalized intersectionsthat were not previously funded for improvements. Sacramento Avenue/C Street and Jefferson Boulevard were identified as focus corridors for bicycle and pedestrian safety. The focus on this corridor resulted in 4 proposed improvements to remedy the safety issues that arise due to the configuration of the 5-lane arterials that have long distances between signalized crossing opportunities. Other considerations such as curved street radius and limited sight lines were considered. Some of the safety measures at these and other proposed improvement’s locations are raised medians, refuge islands, pedestrian crossings at uncontrolled locations, curb extensions, new crosswalk markings, additional crossing signage, center median islands (refuge for pedestrians), new ADA curb ramps, and RRFBs.

The proposed treatments at each of these locations are anticipated to reduce collisions by increasing the visibility of the crossing pedestrians and helping to alert drivers of the pedestrians' presence. While some improvements discussed would introduce signage and clearly identify crossings, other improvements are meant to reduce the exposure experienced by pedestrian. This would be accomplished by visually narrowing the roadway to help reduce speeding, and adding sidewalks, Attachment 3

the curb ramps, and addingcenter raised medians in selected locations, generally at the wider five and four lane roadways. At these locations with numerous lanes, thepedestrian refuge islands that allow people to cross the street as two discrete crossing actions by enabling them to only need to account for one direction of traffic at a time. This has an added benefit of not having to alter through-lanes. Lastly, the presence of RRFBs will provide increased yielding and stopping by drivers and is a systematic improvement throughout the area. Specific improvements for each proposed project improvements is provided immediately below.

Project Improvements

1. Intersection of Lake Washington Boulevard and Southport Parkway – This intersection would be improved with raised medians to replace the existing painted medians on Lake Washington Boulevard. The medians would extend approximately 200 feet north of the intersection and approximately 200 feet south of the intersection.

2. Intersection of Lake Washington Boulevard and Westbridge Plaze Driveway -This intersection would be improved with a single raised median that would be approximately 205 feet in length. This median would prevent cross lane vehicle movements to enter or exit the driveway. Turning movements would be limited to right in and right out from Lake Washington Boulevard.

3. Intersection of Jefferson Boulevard and 15th Street- This intersection would be improved with raised medians to replace the existing painted medians on Jefferson Boulevard. The medians would extend approximately 190 feet north of the intersection and approximately 285 feet south of the intersection.

4. Intersection of Jefferson Boulevard at11th Street. – The project improvements at this intersection would occur within Jefferson Boulevard. North bound and southbound lanes would be painted with a yield bar and receive new yield signs. A new crosswalk from the corner of Jefferson Boulevard at Drever Street to the northerly side of 11th Street would be painted. Improvements also include RRFB poles, curb extensions and ADA compliant ramps at each corner, and a raised center median to facilitate crossing of the two-lane traffic (each direction).

5. Intersection of Sacramento Avenue and Sunset Avenue – This intersection would be improved with three new raised medians. Two medians would be within Sacramento Avenue, would prevent U-turns, would prevent left turns from southbound Sunset Avenue to eastbound Sacramento Avenue. Left turns from Sacramento Avenue to Sunset Avenue would be protected by the median.

6. Intersection of Sacramento Avenue at Solano Street – This “T” intersection would be improved with a new painted pedestrian crosswalk that would span Sacramento Avenue but have a raised center median to facilitate crossing of the four-lane roadway (two lanes in each direction). Curb and sidewalk improvements would be made on the northerly side of the roadway and improved ADA curb ramps would be installed on the southerly side of the street.

RRFB poles would be installed. Sacramento Avenue also would be painted with yield bars and a yield sign would be installed.

7. Intersection of Sacramento Avenue at Simon Terrace – This “T” intersection would be improved with a new painted pedestrian crosswalk that that would span Sacramento Avenue but have a raised center median, with RFB poles, to facilitate crossing of the four-lane roadway (two lanes in each direction). Curb and sidewalk improvements would be made on the northerly side of the roadway and extend up Simon Terrace. Both the northerly and southerly sides of the crosswalk would be improved with ADA curb rampsand RRFB poles on both sides. Sacramento Avenue also would be painted with yield bars and a yield sign installed.

8. Intersection of C Street at 6
th Street – Thisintersection would be improved with painted yield bars and yield signage for northbound and southbound traffic on 6th Street. Southbound lanes would be striped with solid lines and dashed lane indicators. The westerly and easterly sides of 6th Street would be connected with a new painted pedestrian crosswalk, RRFB poles, and ADA compliant curb ramps on both sides of the street. Crosswalk and bulb out may be shifted approximately 50 to the north from what is shown in Figure 10 to better accommodate improvements (existing driveways and utilities).

9. Intersection of Reuter Drive at Andrew Street- This intersection is a four-way stop controlled intersection. The intersection would be painted with four new pedestrian crosswalks. The stop bar would be relocated and stop legends would be pulled back from the intersection. All existing curb ramps would be preserved. xType text here

OB 13-02 March 14, 2013

10. Carrie Street at Bryte Park – This section of roadway would retain the existing ADA curb-ramps, the RRFB would be replaced behind the back of the walk next to the ramp landing and the northerly side would be improved with new RRFB poles.

11. :Poplar Avenue at Westfield Village Elementary School – Poplar Street at this location would be improved with a refreshed painted crosswalk, and new upstream and downstream curb extensions on all four corners of the crosswalk.

Existing ADA curb ramps would be maintained.

12. Quail Road to Columbus Road Shared Use Path – This section of shared use path would be improved with three new ADA curb ramps. Two ADA curb ramps would be installed on the easterly and westerly side of Columbus Road at the intersection with Alturas Court. The third ADA curb ramp would be on the easterly side of Quail Road near the intersection of Goldhill Street.

13. Columbus Road at Stonegate Elementary School and Shared Use Path – this area would be improved by removal of the existing crosswalk and curb ramps on the westerly segment of Columbus Road. This crosswalk would be relocated approximately 100 feet to the east and repainted in more logical location and installed with northerly and southerly ADA compliant curb ramps.

14. La Jolla Street at Stonegate Elementary School – This area would be improved with the removal of the existing cross walk at the intersection of Redding Road and La Jolla Street. The crosswalk would be repainted approximately 50 feet to the north.Both sides of the crosswalk would be improved with ADA compliance curb ramps and signage.

Removals and Excavation
The proposed project would require removal of existing hardscape including sidewalk and asphalt from the roadways, as well as small portions of the adjacent unpaved areas adjacent to the existing sidewalk. Hardscape materials proposed for removal would first be saw cut and then removed using machinery. Removed paving and asphalt would be hauled off-site by dump trucks. Materials would be hauled to a crushing facility to be broken down and recycled for other construction needs such as road base. Removals needed for the improvements would be to a depth of approximately 1-2 feet. Some removals and exaction would exceed this distance if needed to tie into or potentially make horizontal realignments of utilities. Full utility relocations are not anticipated.

After removal of the hardscape within the overall alignment, the proposed project would require minor excavation and earthwork needed to meetfinish grades and install the water quality detention basins along the corridor. It is anticipated that grading would be limited to 1-2 feet. The project alignment would occurin areas that contain utilities includingphone, electric, power poles, gas, cable, sewer, etc. The majority of utilities and utility boxes would be protected in place, but a few would be adjusted to grade. It is anticipated that most of the utilities, if needed, could be modified using vertical or horizontal alignment but it is not known if relocations would be needed.

Improvements and Construction
As discussed above, the proposed project includes the installation of medians, new cross walks, stop limit lines and yield striping, installation of new RRFB boxes, ADA compliant curb ramps, and new sidewalks adjacent to some the improvement areas. The proposed projectdoes not include any roadway improvements including additional lanes or alignment changes.

Construction of the proposed project would not require complete street closures during construction but may temporarily result in short-term single lane closure to facilitate construction and striping activities. Construction is anticipated to occur over a 12-month period. Construction is anticipated to begin in October of 2021 and be completed in 2022.

Brief Explanation of How Project Complies, or Will Comply with Applicable Federal Mandate (Part A):

March 14, 2013 OB 13-02

1. The proposed projectincludes 14 areas within existing City roadway and right-of-way that are proposed for upgrades to medians and pedestrian facilities. The improvements are intended to improve vehicular and pedestrian safety through installation of new medians, crosswalks, stop and yield signage and striping, ADA compliant curb ramps, and, and Rectangular Rapid Flashing Beacons (RRFBs). The proposed project is responsive to and based on deficiencies addressed in the City of West Sacramento Systemic Safety Analysis Final Report (WSSSA) published in December 2018. Allimprovements are in logicallocationbased on the study and all would function independently.

None would require any additional improvements to fully function on their own. In addition, none of the improvement would hinder any future improvements as part of this project or future projects.

2. The proposed project was included in the WSSSA which was adopted by the City in 2018. The WSSSA was developed after a thorough safety analysis that identified numerous pedestrian and safety improvements needed for roadways and intersections within the City. The proposed project focuses on pedestrian safety and would occur within and near both commercial, residential, schools, and recreational areas. The proposed project also helps fulfil City goals to provide safe and efficient multimodal transportation alternatives. Overall,the proposed project would make a substantial contribution to the safety of local roadways, which would be considered a benefit to residents. As such, the proposed project would not generate public controversy.

3. The proposed project includes minor construction at 14 intersections and roadway segments that are designed to enhance safety and access for pedestrians and vehicles.The proposed project does not meet the definition of a Type I project, as it would not reconfigure any roadways to accommodate the proposed improvements. The proposed project would not add any lanes, or increase truck or bus traffic.The proposedimprovements also would not alter the existing vertical or horizontal alignment of any roadway. Lastly, the proposed projectwould not increase or decrease the number of traffic lanes, would not encourage additional vehicle trips, or result in the generation of substantial new noise sources post construction.

4. The proposed project involves construction related activities needed to remove hardscape and reinstall materials at the 14 intersections and roadway sections. The proposed project is anticipated to require some saw cutting and removal of hardscape using machinery and trucks to haul concrete and asphalt debris. The proposed project, however, does not include pile driving or other construction techniques that would result in excessive construction-related noise. Some of the removed materials are anticipated to be broken up on site to facilitate loading into dump-trucks before beinghauledoff-site to be crushed and recycled. Removal of hardscape could generate excessive noise over temporary and short periods of time. All construction operations including saw cutting, excavation, and loading of trucks, would be limited to the hours of 7:00 a.m. to 6:00 p.m. Monday through Friday and 8:00 a.m. to 5:00 p.m on weekends in accordance with City requirements. Approval from the City would be required for work before or after hours. While some of the proposed improvements would occur in commercial and residential areas, theproject areas are small and discrete, and noise generated is considered typical of small improvement projects and construction noise would not make a substantial contribution to the existing noise environment. .

5. The proposed projectis in a NAAQS non-attainment or maintenance area for ground level 1-hour and 8-hourOzone (O3) and fine particulates (PM10) (Yolo County, 2020). The County is out of attainment for the state standard for 1- hour and 8 hour, unclassified for PM10, and out of conformance for the 24 hours PM2.5 (Yolo Air Pollution Control District, 2020). The proposed project would not change vehicular travel routes or roadway capacity, but would improve pedestrian safety and enhance the multimodal transportation network.

6. The proposed projectis considered exempt from the requirement of conformity, as it falls under the “bicycle and pedestrian facilities projects” category shown in 40 CFR 93.126 Table 2.

7. The projecttype is listed in Table 2 of 40 CFR 93.126; therefore, this is not applicable

8. The projecttype is listed in Table 2 of 40 CFR 93.126; therefore, this is not applicable Attachment 3

9. The proposed project includes 14 sites that would undergo pedestrian and roadways improvements including installation of new medians to restrict turning movements aimed at improvingvehicle and pedestrian crossing safety.

Other improvements include restriping and painting, installation of new ADA compliant curb ramps, some replacement of adjacent sidewalks and installation of RRFB crossing boxes. The proposed project would include removal of overlying hardscape and does not propose or require substantial excavation to achieve finished grades.

As such, the risk of upset of unknown hazardous materials is minimal. The California Waterboards Geotracker Website and Department of Toxic Substances Control (DTSC) were used to determine the number of location of listed hazardous materials sites that may occur within or immediately adjacent to a construction area. Each location of project improvements was evaluated, and the findings are listed below.

Intersection1: Lake Washington Boulevard and Southport Parkway –There is a permitted underground storage tank for Takahar West AM/PM listed near the location on the Geotracker webstite. No listing appears on Envirostor. No violations are listed.

Intersection 2: Intersection of Lake Washington Boulevard and Westbridge Plaza Driveway -There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area Intersection 3: Jefferson Boulevard and 15th Street-There is one site (Ricky’s Beacon) located at 45 15th Street listed as a leaking underground storage tank (LUST) site but that closed as of 10.4, 2011. A second site (Kamboj Oil Inc) a smog check station has a permitted underground storage tank (UST). No violations are noted. Neither site is listed on the Envirostor database.

Intersection 4: Jefferson Boulevard at 11th Street. There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 5: Sacramento Avenue and Sunset Avenue – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 6: Sacramento Avenue at Solano Street -There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 7: There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 8: 6th Street and C Street – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 9: Reuter Drive at AndrewStreet-There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 10: Carrie Street at Bryte Park – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 11: Poplar Avenue at Westfield Village Elementary School – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area Intersection 12: Quail Road to Columbus Road Shared Use Path – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 13: Columbus Road at Stonegate Elementary School and Shared Use Path – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Intersection 14: La Jolla Street at Stonegate Elementary School – There are no listed sites on either the Geotracker or Envirostor website within or immediately adjacent to this project area.

Due to location of the proposed improvements and lack of hazardous materials sites within areas proposed for disturbance, construction is not anticipated to encounter any hazardous materials or result in upset conditions.

10. The proposed project would occur entirely within existing roadway right of way and is not located within or adjacent to any water resources rivers, streams, bays, inlets, lakes, or drainage sloughs, vernal pools, or any other water resource. The proposed project does not include the removal or discharge of any fill to any water.

11. The proposed project is located in the City of West Sacramento in Yolo County and is not in the vicinity of a solesource aquifer. According to the United States Environmental Protection Agency (EPA), the nearest sole source aquifer is the Santa Margarita in Scotts Valley aquifer approximately 107 miles to the southwest (EPA, 2020).

12. The proposed project is not in a Coastal Zone. The nearest coastal zone is located approximately 78 milesto the east.

13. According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRM) Panel Number 0607280005B, (effective 01/19/1995)(FEMA, 1995), the proposed project improvements are located in an area with no digital data available. The City is located adjacent to the Sacramento River and flood protection is provided by a series of levees. The West Sacramento General Plan (WSGP) does identify that the City is within a 200-year floodplain. The City website notes that most of West Sacramento is currently designated Flood Zone X, which meansthere is not a statutory requirement for flood insurance. New construction and expansion of existing structures are allowed in Flood Zone X without being subject to elevation and flood-proofing requirements. FEMA is currently evaluating the existing designation and it is possible they will change the designation to a Special Flood Hazard Area (City of West Sacramento, 2020).

The City of West Sacramento Flood Project also is working to meet flood control standards by 2025 that have been imposed by the State.Thecities efforts are intended to continue to make levee improvements and achieve a 200-year level of flood protection (City of West Sacramento, 2020). The proposed project would not interfere with any improvements or affect flood flows or floodplain designations. The proposed project includes improvements to existing roadways and sidewalks and would install ra ised medians, restripe crosswalks, and improve stop controls, intended to enhance pedestrian safety. All improvements would occur within existing right of way and occur in areas with existing hardscapes. The proposed project does not propose any new structuresandwould not induce growth to a flood zone. The proposed project also would not encroach into any existing regulatory floodway, and would not affect existing drainage patterns.

14. The City of West Sacramento is on the western bank of the Sacramento River. A portion of the American River that flows into the Sacramento River from its eastern side is mapped as a wild and scenic river. The confluence is approximately 0.12 miles from the City of West Sacramento and greater than 0.25 miles from any of the proposed improvements. The proposed project consists of pedestrian improvements within existing roadways and sidewalks largely in the interior of the City. None of the improvements are in, across, or adjacent to the river, and none of the improvements would be visible from the American River or obstruct views of the American River.

15. The proposed improvements are located within the existing rights-of-way and adjacent sidewalks and would not encroach on any undeveloped or previously undisturbed area. The proposed project would not directly impact any native habitat or critical habitat that would be used by a federally listed threatened or endangered species.The area surrounding the proposed improvements is highly urbanized with commercial and residential uses. The proposed project site would occur entirely in paved areas and would not disturb any aquatic resources or fish habitat. The project sites do not provide habitat linkages andthe project area does not provide logical connectivity to anyoff-site undisturbed habitat areas. Special status species that were determined to have the potential to occur in the vicinity of the project site and that could be affected was prepared by the United States Department of the Interior – Fish and Wildlife Service (USFWS) based on an Information for Planning and Consultation (IPac) website. These species include least Bell’s Vireo (Vireo Bellii pusillus), Giant Garter snake (Thamnophis gigas), California Red-legged Frog (Rana draytonii), Calfironia Tiger Salamander (Ambystoma californiense), Delta Smelt (hypomesus tranpacificus), Valley Elderberry Longhorn Bettle (Democerus californincus dimophus), Vernal pool Fairy shrimp (Banchinecta lyunchi), and Vernal Pool Tadpole Schrimp (Lepidurs packardi). The project area also is shown in critical habitat for the Delta Smelt. As discussed above, the proposed project would occur entirely within existing roadways and roadway right-of-way, adjacent sidewalks, and areas dominated by hardscape and that are heavily disturbed. The project site does not provide any areas that would provide habitat for any of the listed species.

16. As discussed in sub 15), the project site occurs in a highly urbanized and disturbed environment and would not remove any native vegetative habitats. Some of the project areas are located adjacent undeveloped areas with nonnative landscaping, including trees, and upland ruderal vegetation. The proposed projectwould not remove any trees, and the proposed project is unlikely to affect any migratory or nesting birds. None-the-less prior to project implementation if construction occurs during the nesting season, as a part of the standard permitting conditions, a nesting bird survey would be conducted by a qualified biologist and appropriate measures to minimize disturbance would be implemented if needed.

17. As discussed in sub 15) and 16) above, the project site is highly urbanized, and improvements would occur within existing paved right-of-wayand/or previously disturbed areas. There are no waters in the project site andthe National Wetlands Inventory surface water and wetlands mapping tool, does not identify any waters within or adjacent to the project sites(USFWS, 2020).

18. The proposed project would occur in a completely urbanized environment and there is no agricultural land within, adjacent to, or surrounding the project site. No agricultural wetlands would be disturbed.

19. Construction equipment needed for the proposed projectwould be staged in an area to be determined after issuance of the construction contract. The project site consists of paved hardscape in existing right-of-way and access through or use of undeveloped areas containingnon-native weedy species would not be required.All construction equipment would be washed prior to reaching and entering any area of the construction sites. The potential for the proposed project to result in the spread of non-native noxious weeds is remote.

20. The proposed project site is within a highly urbanized areas and within the existing right-of-way. The areas surrounding the proposed improvement areas are largely characterized by commercial, and residential sites. Only one of the sites, Intersection 10 at Carrie Street, would be located a djacent to an existing public park. Improvements at this site would retain the existing ADA curb-ramps, and a RRFB would be installed and the crosswalk would be restriped. These project elements would improve connectivity between the park on the north, the Alyce Norman Elementary School, and Alyce Norman Educational Center, and improve access to these recreational resources from surrounding residential areas. All project improvements would occur in previously disturbed and paved areas and the proposed project would not negatively impacts any publicly owned parks, recreation areas, wildlife or waterfowl refuges.

21. The proposed project would not occur in an area using National Park Service (NPS) Land and Water Conservation Funds (LWCF). The proposed projectis not shown on the most current LWCF map provided by the LWCF coalition website. (LWCF, 2020).

22. The proposed project is within existing roadway rights-of-way and areas that have been heavily disturbed and are characterized by hardscape. Many of the areas have existing pedestrian facilities and these would be improved and enhanced for safety, including raised medians within some of the existing roads and right-of-way. The proposed project does not include removals of existing vegetation, and does not include the installation of any elevated structures that could obstruct viewsheds or block site lines. The existing topography of the project areas is flat and there would be no changes to any significant landforms, existing structures, nor does the proposed project include obtrusive signage or lighting. The proposed project scored a 7 using the Visual Impact Assessment Questionnaire (refer to Appendix E) (Caltrans, 2020b). Visual changes would be minimal and would not change substantially change the existing urbanized landscape.

23. The proposed project is located entirely within existing disturbed and paved right-of-way. The proposed project would not require the take or relocation of any structures, businesses, or homes.

24. The proposed project would occur within the existing travel lanes and sidewalks of project related roadways and intersections. The proposed project would not require any full or partial takes of any non-public right-of-way.The proposed improvements may require the lateral movement of some utilities, but utility relocations area not anticipated.

25. The proposed project would be consistent with the City of West Sacramento Highway Safety Improvement Plan (HSIP). The HSIP was prepared by the City for the purpose of identifying intersection improvement that would result in increased pedestrian safety. All of the proposed improvements were specifically called out and described in the HSIP. Therefore, the proposed project is consistent with this City document as well as the City of West Sacramento General Plan (WSGP). The WSGP discusses the multimodal transportation system to include connectivity, safety, and integration, for vehicles, pedestrian, bicycles, and connections to residential, commercial, employment, and transportation centers (West Sacramento, 2035).

26. The proposed projectincludes the construction of newpedestrian safety improvements that would improve the multimodal transportation network in 14 locations. The proposed project would increase accessibility through theseareas by improvement safety and thereby encouraging connectivity and cohesion within surrounding neighborhoods and communities. The proposed project would not impair the economic vitality of any businesses or reduce accessibility to community resources such as parks, shopping areas, or emergency services. The proposed project is in a highly urbanized areas, would occur within existing right-of-way and therefore, and would not result in the physical division of any neighborhoods or communities. The proposed project would promote and provide a new alternative multimodal transportation connectionbetween neighborhoods and communities, commercial areas, recreational areas.

27. The proposed project would provide improved pedestrian road crossing and encourage the future development of a multi-modal transportation network. No residences or businesses would be relocated, the proposed projectwould be located at 14 locations throughout the City, overall is considered to be a beneficial use, and it would not disproportionately affect low-income and/or minority populations.

28. The proposed project would require removal of existing hardscape and minor excavation to install some of the new improvements. In some locations there may be shallow utilities. In these locations, construction may necessitate horizontal movements or adjustment of existing utilities to finished grades. Utilities that may require adjustments could include electrical, water, natural gas, telephone, storm drain, and sanitary sewer. All utility adjustment would occur within existing right-of-way and are anticipated to only include, when required, minor modifications to horizontal or vertical alignment. Utility relocations are notanticipated.

29. The proposed project includes the improvements at 14 intersections and roadway locations within the City. As discussed above, the proposed project would improve pedestrian safety and vehicle turning movements across lanes of traffic. All improvements would occur within existing roadways and adjacent right-of way. The proposed project would continue the prohibition ofthe southerly left turn to Westbridge Plaza using temporary flexible bollardsfrom Lake Washington Boulevard. The prohibition of the left turn from the same driveway to southbound Lake Washington Boulevard also would be continued. This change is not considered substantial and the driveway would remain usable for ingress and egress. Two other full access driveway on Southport Boulevard would remain available.

The proposed improvements at C Street and 6th Street (crosswalk bulb out) may be shifted approximately 50 to the north from what is shown in Figure 10 to better accommodate improvements (existing driveways and utilities.

Therefore, access to adjacent properties would not be substantially affected. All other improvements are primarily adjacent to existing residential areas and would increase pedestrian safety and access to and through these areas.

30. The locations of the 14 proposed improvements do not occur in proximity to any state highway system and would not affect the operation of any on- or off-ramps to the state highway system. The project would not affect any other connection point, or interfere within any mainline freeway lanes.

31. The proposed project would be implementedso that no road closures are required. The proposed projectmay require temporary closure of a single lane(s), but access to through traffic at all the project sites would be maintained. As such no detours would be required. Lastly, the proposed project does not occur in proximity to the state highway system and no ramp closures would be required.

32. The proposed project would occur within the existing right-of-way of existing streets and intersections and would not result in loss of parking. The proposed project would result in the removalof approximately 12 feet of curb-space on the easterly side of La Jolla Street. The entire curb between residential driveways, however, is approximately 28 feet and is not adequate to provide parking for two vehicles. With the project, adequate parking for a single vehicle would remain. In addition, the existing crosswalk and curb ramps at the corner of La Jolla Street and Redding Road would be removed and replaced with a solid curb. This would increasethe curb distance at this location and provide adequate space to enable curbside parking for one additional vehicle. Thus, no parking at the location of improvements would be lost.

33. The proposed project is located within existing disturbed and paved areas, within existing City right-of-way. The proposed project would not occur on any state or federal land.

34. The proposed project is in an urbanized area and almost entirely within existing paved right-of-way. There is no farmland within or adjacent to the project site. The California Department of Conservation (CDOC)-California Important Farmland Finder does not identify any Prime Farmland, Farmland of Statewide Importance, or Unique Farmland within or adjacent to the proposed project. The proposed project is in an areas shown as Urban and Built up land. The proposed project would not convert any farmland (CDOC, 2016).

35. A Cultural Resources Study will be undertaken by professionally qualified staff (PQS) in order to satisfy the requirements of Section 106 Programmatic Agreement.

36. The proposed project is located within existing disturbed and paved areas, within existing right-of-way. The proposed project is not within or adjacent to Tribal Land.

Consultation Code: 08FBDT00-2021-SLI-0013
Event Code: 08FBDT00-2021-E-00036
Project Name: West Sacramento HSIP - Area 1 (SW)
Subject: List of threatened and endangered species that may occur in your proposed project location, and/or may be affected by your proposed project To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).

New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list.

The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.

▪
A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at:
http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html.

We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Event Code: 08FBDT00-2021-E-00040
Project Name: West Sacramento HISP (east central)
Subject: List of threatened and endangered species that may occur in your proposed project location, and/or may be affected by your proposed project To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).

New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list.

The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.

▪
A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at:
http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html.

We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

10/20/2020 Questionnaire to Determine Visual Impact Assessment (VIA) Level | Caltrans https://dot.ca.gov/programs/design/lap-visual-impact-assessment/lap-via-questionnaire 1/5 Home Programs Design Visual Impact Assessment VIA Questionnaire Questionnaire to Determine Visual Impact
Assessment (VIA) Level
Use the following questions and subsequent score as a guide to help determine the appropriate level of VIA documentation. This questionnaire assists the VIA preparer (i.e. Landscape Architect) in estimating the probable visual impacts of a proposed project on the environment and in understanding the degree and breadth of the possible visual issues. The goal is to develop a suitable document strategy that is thorough, concise and defensible.

Enter the project name and consider each of the ten questions below. Select the response that most closely applies to the proposed project and corresponding number on the right side of the table. Points are automatically computed at the bottom of the table and the total score should be matched to one of the five groups of scores at the end of the questionnaire that include recommended levels of VIA study and associated annotated outlines (i.e., minor, moderate, advanced/complex).

This scoring system should be used as a preliminary guide and should not be used as a substitute for objective analysis on the part of the preparer. Although the total score may recommend a certain level of VIA document, circumstances associated with any one of the ten question-areas may indicate the need to elevate the VIA to a greater level of detail. For projects done by others on the State Highway System, the District Landscape Architect should be consulted when scoping the VIA level and provide concurrence on the level of analysis used.

The Standard Environmental Reference, Environmental Handbook, Volume I: Chapter 27-Visual & Aesthetics Review lists preparer qualifications for conducting the visual impact assessment process.

Landscape Architects receive formal training in the area of visual resource management and can appropriately determine which VIA level is appropriate.

Preparer Qualifications:
"Scenic Resource Evaluations and VIA's are performed under the direction of licensed Landscape Architects. Landscape Architects receive formal training in the area of visual resource management with a curriculum that emphasizes environmental design, human factors, and context sensitive solutions. When recommending specific visual mitigation measures, Landscape Architects can appropriately weigh the benefits of these dierent measures and consider construction feasibility and maintainability."

1. Will the project result in a noticeable change in the physical characteristics of the existing environment?
Consider all project components and construction impacts - both permanent and temporary, including landform changes, structures, noise barriers, vegetation removal, railing, signage, and contractor activities.

No Noticeable Change (0 points)

2. Will the project complement or contrast with the visual character desired by the community?
Evaluate the scale and extent of the project features compared to the surrounding scale of the community. Is the project likely to give an urban appearance to an existing rural or suburban community? Do you anticipate that the change will be viewed by the public as positive or negative? Research planning documents, or talk with local planners and community representatives to understand the type of visual environment local residents envision for their community.

High Compatibility (1 point)

3. What level of local concern is there for the types of project features (e.g., bridge structures, large excavations, sound barriers, or median planting removal) and construction impacts that are proposed?
Certain project improvements can be of special interest to local citizens, causing a heightened level of public concern, and requiring a more focused visual analysis.

Negligible Project Features (0 points)

4. Will the project require redesign or realignment to minimize adverse change or will mitigation, such as landscape or architectural treatment, likely be necessary?
Consider the type of changes caused by the project, i.e., can undesirable views be screened or will desirable views be permanently obscured so a redesign should be considered? No Mitigation Likely (0 points)

5. Will this project, when seen collectively with other projects, result in an aggregate adverse change (cumulative impacts) in overall visual quality or character?
Identify any projects (both Caltrans and local) in the area that have been constructed in recent years and those currently planned for future construction. The window of time and the extent of area applicable to possible cumulative impacts should be based on a reasonable anticipation of the viewing public's perception.

Cumulative Impacts Unlikely to Occur (1 point)

10/20/2020 Questionnaire to Determine Visual Impact Assessment (VIA) Level | Caltrans https://dot.ca.gov/programs/design/lap-visual-impact-assessment/lap-via-questionnaire 3/5 Viewer Sensitivity

1. What is the potential that the project proposal will be controversial within the community, or opposed by any organized group?
This can be researched initially by talking with Caltrans and local agency management and sta familiar with the aected community's sentiments as evidenced by past projects and/or current information.

Low Potential (1 point)

2. How sensitive are potential viewer-groups likely to be regarding visible changes proposed by the project?
Consider among other factors the number of viewers within the group, probable viewer expectations, activities, viewing duration, and orientation. The expected viewer sensitivity level may be scoped by applying professional judgment, and by soliciting information from other Caltrans sta, local agencies and community representatives familiar with the aected community's sentiments and demonstrated concerns.

Low Sensitivity (1 point)

3. To what degree does the project's aesthetic approach appear to be consistent with applicable laws, ordinances, regulations, policies or standards?
Although the State is not always required to comply with local planning ordinances, these documents are critical in understanding the importance that communities place on aesthetic issues. The Caltrans Environmental Planning branch may have copies of the planning documents that pertain to the project. If not, this information can be obtained by contacting the local planning department. Also, many local and state planning documents can be found online at the California Land Use Planning Network.

High Compatibility (1 point)

4. Are permits going to be required by outside regulatory agencies (i.e., Federal, State, or local)?
Permit requirements can have an unintended consequence on the visual environment.

Anticipated permits, as well as specific permit requirements - which are defined by the permitted, may be determined by talking with the project Environmental Planner and Project Engineer. Note:
coordinate with the Caltrans representative responsible for obtaining the permit prior to communicating directly with any permitting agency.

No (1 point)

5. Will the project sponsor or public benefit from a more detailed visual analysis in order to help reach consensus on a course of action to address potential visual impacts?
Consider the proposed project features, possible visual impacts, and probable mitigation recommendations.

No (1 point)
