EXECUTIVE SUMMARY
This analysis describes the effect of the Natoma Senior Apartments project (the Project) on the motorized and unmotorized transportation systems in Folsom, California' This study has been prepared for the C6y of Folsom (City), Helix Environmental lnc., and FCC 50, LLC. A Planned Development permit and Conditional Use Perrnit are requested by the applicant for the proposed 136 age-restricted affordable apartments'
Proiect Description
Figure ES-l provides a Project vicinity map. The Project consists of 136 one- and two-bedroom affordable, age restricted, apartrnents located across from the main entrance to Folsom State prison at 102 Natoma St, Folsom, CA 95530 (parcel 071-0320-042). Two access points to East Natoma St are planned: a full access driveway aligned with Prison Rd, and a right-in-right-out driveway near the eastern edge of the Project site. One hundred thirty-six parking stalls are included along the drive isle along the southern and eastern edges of the Proiect. A preliminary site plan is provided as Figure ES-2.

Accessible pathways are planned around the building to provide a walking path for residents.

Sidewalks along the Project's East Natoma Sffeet frontage are included from Prison Rd to the edge of the existing sidewalk at Cimmaron Circle. The existing multi-use trail connection from the Oak parkway trail will be preserved, and a pedestrian connection will be added southernly from the Project to the Oak Parkway Trail.

The site is designated Professional-Office (PO) in the General Plan and zoned as Business professional- Planned Development District (BP-PD). With the Planned Development Permit and conditional Use Permit being requested the Prolect is consistent with the adopted General Plan and zoning,

The analysis considers the traffic operations at intersections in Folsom that could potentially be impacted by project traffic. This TIS considers two study scenarios:
o Existing 2022 without Project condition
r Existing 2022 with Project condition
The two driveway intersections (shown in Figure ES-2) were evaluated for conformity to City policies and policies from the adopted Folsom General Plan. lnternal circutation and sight lines, parking supply and fire access were all considered'

2. East Natoma St/Eastern Proiect DrivewaY (sssc)
Findines
Project impacts are anticipated to be less than significant. Ten project specific findings are made' Finding 1{Trip Generatlon}: The Project is anticipated to Senerate 441 daily vehicle trips including 39 AM peak-hour vehicle trips, and 41 PM peak-hour vehicle trips. Fewer than 50 peak-hour project trips are proiected to pass through any intersection' Finding 2 (Level-of-Service): All study intersections are anticipated to operate at level-of-service B or better under all study scenarios. The Project is not projected to create new deficiencies or worsen existing traffic level-of-service, pursuant to General Plan Policy M4.1.3. lmpacts to level- of-service are considered less than significant'
Finding 3 (Vehicle Miles Traveled): Per capita Project VMT is projected to be at least 15% less than regional per capita VMT. Project VMT impacts are considered less than significant' Finding 4 (Parking): The proposed parking supply of 135 spaces (1'00 spaces per unit)' The Project was found to be adequately Parked'
Finding 5 (Minimum Required Throat Depth!: The standards for driveway throat depths are met.

Finding 6 {Emergency vehicle Access): Emergency vehicle access is adequate' Finding 7 {Pedesgian and Bicycle}: The Project does not result in impacts to pedestrian and bicycle facilities. lmpacts to pedestrian and bicycle facilities are considered less than significant.

Finding 8 (Transitf: The Project does not result in impacts to transit facilities. lmpacts to transit facilities are considered less than significant'

Natoma Senior APartments Folsom,
CaliforniaTransportation lmpact Study
Finding 9 (Driveway Geometry): Proposed geometry for access to East Natoma St is adequate' Either a raised median or right-turn channelization should be used to limit the secondary (eastern) driveway to right-in-right-out access' Note that the secondary (eastern) driveway was modeled assuming a shared eastbound through-right turn lane, without a right turn taper or deceleration lane. Anticipated eastbound right turning volume is less than 10 vehicles during the AM and PM peak-hours and neither a right tapper or deceleration lane is required per city of Folsom policy' However, the c1y reserves the right to require either a taper or pocket at the discretion of the City Engineer. Finding 10 (Signal timing): With the addition of a fourth leg to the East Natoma St/Prison Rd intersection, the signal timing and lane geometry was assumed to be configured as follows, or an equivalent plan to the satisfaction of the city Engineer:
r Eastbound: An eastbound right turn pocket was assumed with 150-feet of storage and a 60-foot taper; for a total of one left, one through, and one right turn lane' . Westbound:Awestbound leftturn lanewith 100-foot pocket plus5O-foottaperforatotal of one left and one shared Through-right lane'
. Southbound: The existing exclusive right-turn lane is assumed to be restriped as a through-right turn lane (for a total of one left and one shared through-right)' e Northbound: The northbound approach is assumed to provide one left and one shared through-right lane. The northbound through-right lane is assumed to be in a 70' turn pocket Plus 60'taPer.
o Timing: Eastbound and westbound protected left turn phasing, northbound and southbound split phasing. 150 second cycle length, with 34 second northbound southbound split phases and 20 second eastbound and westbound protected phases, and G2 second eastbound and westbound through phases. Crosswalks are assumed across all legs of the intersection with flashing don't walk phases set to 22 seconds to accommodate a 3 foot per seconding walking speed'
city staff have noted that the East Natoma st/Prison Rd intersection may be an excellent location for protected-permissive left-turn phasing (i.e., "a flashing yellow arrow" to allow left turns during the conflicting through phase). Such phasing would increase the intersection capacity and reduce queuing for the eastbound through movement. lt is our professional judgement that novel phasing plans, such as protected-permissive phasing, have the potentialto confuse elderly drivers and pedestrians, resulting in increased accident rates. Because protected-permissive phasing is not necessary to maintain the General Plan level-of-service goals we do not recommend it for the entrance to age-restricted housing. The project adds a fourth leg to the existing T-intersection, which requires upgrading the traffic signal hardware. At the discretion of the city Engineer, those upgrades may include video vehicle detection, connecting the signal into the City traffic management center, and traffic signal controller upgrades to the satisfaction of the City Engineer' conditions of approval can be limited to the city of Folsom standard conditions plus a requirement to time the traffic signal at East Natoma St/Prison Rd to be consistent with finding 10 above, or a similar timing plan, to the satisfaction of the city Engineer' &I:KHAR \l ! :,:a \t i \"t,|:a. a ; { : I, (. t:.'.t t r

1. INTRODUCTION
This Transportation lmpact Study (TlS) identifies impacts of the proposed Natoma Senior Apartments proiect (the Project) on the motorized and unmotorized transportation systems in Folsom, California. This study has been prepared forthe City of Folsom (City), Helix Environmental lnc., and FCC 50, LLC. A Planned Development Permit and Conditional Use Permit are requested by the applicant.

L.L Project DescriPtion
Figure 1 provides a Project vicinity map. The Project consists of 136 one- and two-bedroom affordable, age restricted, apartments located across from the main entrance to Folsom State prison at 103 E. Natoma St, Folsom, CA 95630 (parcel 071-0320-042). Two access points to East Natoma St are planned: a full access driveway aligned with Prison Rd, and a right-in-right-out driveway near the eastern edge of the Projeci site. One hundred thirty-six parking stalls are included along the drive iste along the southern and eastern edges of the Project.

Accessible pathways are planned around the building to provide a walking path for residents.

Sidewalks along the Project's East Natoma Sfeet frontage are included from Prison Rd to the edge of the existing sldewalk at Cimmaron Circle. The existing multi-use trail connection from the Oak parkway trailwill be preserved, and a pedestrian connection will be added southernly from the Project to the Oak Parkway Trail.

2, SCENARIOS, SETT1NG AND STUDY AREA
The project generates fewer than 50 peak-hour trips which is the City's threshold for requiring the evaluation of project traffic on the level-of-service at potential affected intersections.

Consequently, this TIS evaluates traffic operations at the two Projed driveway intersections.

2.1 Study Scenarios
Four scenarios were identified for inclusion in this TIS through consultation with City staff. These study scenarios were used to evaluate Project impacts relevant to General Plan Policy M4.1'3 relative to level of service. This study determines the weekday AM peak-hour, PM peak-hour, and Sunday peak-hour level-of-service at study intersections under the following scenarios:
r Existing 2022 without Project condition
r Existing 2O22with Project condition
Analysis of the existing condition reflects the traffic volumes and roadway geometry at the time the study began, This scenario quantifies performance measures for the existing condition and serves as a known reference point for those familiar with the study area' These scenarios, with and without the project, identify Project related impacts anticipated to occur if the Project opened in 2020.
2,2 Project Area RoadwaYs
Brief descriptions of the key roadways serving the Project site are provided below' Natoma StlEast Natoma St is a two-lane minor arterial connecting from Folsom Blvd, past Folsom City Hall, and connecting through Green Valley Rd and onto Empire Ranch Rd. From Folsom Blvd to Fargo Way, just east of City Hall, there are sidewalks, curb, and gutter with striped class 2 bike lanes. From Fargo Way to the east, fronting the Project site and Folsom State Prison, there are dirt shoulders without sidewalks until Folsom Crossing Rd, where East Natoma Street becomes a four-lane arterialwith sidewalk, curb, gutter, and striped class 2 bike lanes to Empire Ranch Rd.

At Coloma Street, near City Hall, Natoma St caries about 11,000 vehicles per day. A volume which drops to about L0,000 vehicles per day near the Project Site' prison Rd is a two-lane north-south access road from East Natoma 5t to Folsom State Prison. lt has unpaved shoulders without bike lanes or sidewalks. Prison Road is signed to prohibit stopping or turning within the prison's property'

2.4 Transit
Folsom,s public transportation includes bus and dial-a-ride service provided by the City through Folsom Stage Lines and light rail seruice provided by Sacramento RegionalTransit District {SRTD)' El Dorado County Transit (EDC Transit) also provides limited bus connections to El Dorado County.

Folsom Stage Lines and Dial-A-Ride
The Folsom Stage Line buses, operated by SRTD run Monday through Friday and there is no weekend service available. There are currentlyten buses running on three routes. They are routes 10, 20 and 30 (Figure 3). Routes 10 and 20 intersect at Folsom Lake college. There is no charge to transferfrom one Folsom Stage Line route to another,
r Route 10 - Serves Historic Folsom, E. Bidwell St., the Broadstone Market Place, Broadstone plaza, Folsom Aquatics Center, Folsom Lake College, lntel, Kaiser Permanente, Folsom premium Outlets, Mercy Hospital, Palladio Mall, and CenturyTheatres. lt connects to light rail and with the RT bus service Line 24. Service with a one-hour headway starts at 5:25 AM with the last pickup at 7:25 PM.
r Route 20 - Serves Empire Ranch Road, East Natoma Slreet, Vista del Lago High School, Folsom Lake College and transfers to Route 10. There are one morning and two afternoon buses on Route 20.
e Route 30 - Serves Folsom State Prison, City Hall, and Woodmere Drive during peak-hours (5 a.m. - 8:10 a.m. and 2:35 p.m, - 4:55 p.m.) with four AM peak-period buses and five PM peak-Period buses.

Dial-A-Ride is a curb-to-curb transportation service that operates within the Folsom city limits' lt provides transportation to residents who have a physical, developmental, or mental disability.

Senior citizens who are 55 years of age or older also qualify for this program' Sacramento Regional Transit
SRTD light rail provides light rail service via the Gold Line connecting the Historic Folsom, Glenn, and lron point light rail stations to downtown Sacramento and points in between. Service is Slrnr,qn

Folsom Bikeway Master Planl which provides a framework for the design of a bikeway system that meets the California Street and Highway Code Section 890-894.2 - Bicycle Transportation Act and improves safety and convenience for all users. An updated bike plan is currently being prepared as part of the Folsom Active Transportation Plan. There are four types of bicycle facilities (Class 1, 2,3, and 4) in Folsom.

Class 1 Bike path: A bikeway physically separated from motorized vehicular traffic by an open space or barrier and either within the highway right-of-way or within an independent rlght-of-way (Figure 4).

Class 2 Bike Laner Any portion of roadway designated for bicycle use and defined by pavement marking, curbs, signs, or other traffic-control devices (Figure 4),
Class 3 Bike Route: A designated route through high demand corridors on existing streets and are usually shared with motor vehicles. Are indicated by periodic signs and do not require pavement markings (Figure 4)' A variant on Class lll bikeways, shared lanes, or "sharrow" lanes, are becoming more common, sharrows are a form of class lll bikeways where the general-purpose lane is too narrow for a bicycle and a vehicle to travel safely side-by-side within the same lane. A sharrow symbol painted (Figure 5) on the roadway is used to indicate the likely lateral location of bikes in the lane to inform motor vehicles. class 4 Bikeway (separated Bikeway or "cycle Track") The Protected Bikeways Act of 2o14 (Assembly Bill 1193 - Ting, Chapter 495) established class lV bikeways for California' Class lV bikeways provide a right-of- way designated exclusively for bicycle travel adjacent to a roadway and which are protected from vehicular traffic. Types of separation include, but are not limited to, grade separation, flexible posts, inflexible physical barriers, or on-street parking' An example is shown in Flgure 6.

Figure 7 provides a Folsom bike map. All road segments in the study area include Class 2 bike lanes. There are existing Class 1 trails paralleling the northern edge of East Natoma St (The Johnny Cash Trail, connecting Historic Folsom, Folsom Prison, and Folsom Lake). An existin6 Class ltrail also follows underneath the high voltage line behind the Project site {the oak Parkway Trail).

Grade separated bike/pedestrian tunnels take these trails under Prison Road and East Natoma l Folsom {2007) Bikeway Master Plan,

3. M ETHODOLOGY
This section provides a process overview, describes traffic forecasting, and discusses the methods/criteria used to evaluate level-of-service. Discussion of significance criteria is included.

3.1 Process Overview
The overall analysis process was structured to identifu potential adverse transportation effects related to the project and evaluate consistency with General Plan Policy M4.1'3 relative to traffic leveFof-seruice.
r Traffic volumes and turning movements for the Existing 2022 Condition were determined from observed traffic counts taken Tuesday December 7,2O2t' . Study intersection traffic operations were analyzed both with and without the proposed project to identify any anticipated inconsistencies with General Plan Policy M4.1.3 relative to traffic level of service.
o California Environmental euality Act {CEQA) impacts are based on qualitative vehicle miles of travel (VMT) analysis and significance criteria from the General Plan (Policy NCR

3.1.3), and CEqA guidance from the Governo/s Office of Planning and Research2 3.

3.2 Level-of-service Methodology
LeveFof-service {LOS) is a qualitative indication of the level of delay and congestion experienced by motorists using an intersection. Levels-of-service are designated by the letters A through F, with A being the best conditions and F being the worst (high delay and congestion). Calculation methodologies, measures of performance, and thresholds for each letter grade differ for road segments, signalized intersections, and unsignalized intersections.

Based on guidance from City staff, the following procedures described below for intersection traffic operations analysis were utilized for this TIS' Intersection Traffic Operations Analysis
Signallzed lntersFctions
The methodology from the Highway Capacity Manual (HCM) 6th Editiona, are used to analyze signalized intersections. Level-of-service can be characterized for the entire intersection, each approach, or by lane group. Control delay alone (the weighted average delay for all vehicles entering the intersection) is used to characterize leveFof-service for the entire intersection or an approach. Control delay and volume to capacity ratio are used to characterize level-of-service for lane groups. The average delay criteria used to determine the level-of-service at signalized 2 OpR (2018) Technical Advisory on Evaluating Transportation lmpacts ln CEQA, httul,l*ro,opr,qi!ssrdss.t-ag.L9gg:Zgl-:e$!id- Atl!.isury..pdt' 3 oPR's webinar on sB 743 implementation,4h6/2020'

intersections is presented in Table 2. The HCM 2010 methodology is used as the primary method' HCM 2000 methods are only utilized where the signal phasing is incompatible with HCM 2010 methods.

Poor progression and long cycle lengths may atso contribute to such delay levels'
Note 1l Welghted average of delay on all aPProaches' This is the measure used by the Highway Capacity Manual to determine level-of-service, Any movement with a volume-to-capacity ratio (v/c) greater than 1'0 is considered to be level-of-service F' Source: Transportation Research Eoard (2015) Highway Capacity Manual 6th Edition, Washington D'C' U nsisnalieed lntertections
The methodoloBv from HcM oth Edition is used for the analysis of unsignalized intersections. At an unsignalized intersection, most of the main street traffic is un-delayed and, by definition, have acceptable conditions. The main street left-turn movements and the minor street movements are all susceptible to delay of varying degrees. Generally, the higher the main street traffic volumes, \:,t \,tt.il i 1 (: ;:\{', \1-..( "{it?,ffi rKEAR

the higher the delay for the minor movements. Separate methods are utilized for Two-Way Stop- Controlled (TWSC) i ntersections a nd Al l-Way Sto p-Co ntrol led (AWSC) inte rsections. r TWSC: The methodology for analysis of two-way stop-controlled intersections calculates . an average total delay per vehicle for each minor street movement and for the major street left-turn movements, based on the availability of adequate gaps in the main street through traffic. A level-of-service designation is assigned to individual movements or 'combinations of movements {in the case of shared lanes} babed upon delay, it is not defined for the intersection as a whole. Unsignalized intersection level-of-service is for each movement {or group of movements) based upon the respective average delay per vehicle. Table 3 presents the average delay criteria used to determine the level-of-service at TWSC and AWSC intersections'
o AWSC: At all-way stop-controlled intersections, the level-of-service is determined by the weighted average delay for all vehicles entering the intersection. The methodologies for these types of intersections calculate a single weighted average delay and leveFof-service for the intersection as a whole. The average delay criteria used to determine the levelof- service at all-way stop intersections is the same as that presented in Table 3. Level-of- service for specific movements can also be determined based on the TWSC methodology.

It is not unusual for some of the minor street movements at unsignalized intersections to have level-of-service D, E, or F conditions while the major street movements have level-of-service A, B, or C conditions. ln such a case, the minor street traffic experiences delays that can be substantial for individual minor street vehicles, but the majority of vehicles using the intersection have very little delay. Usually in such cases, the minor street traffic volumes are relatively low. lf the minor street volume is large enough, improvements to reduce the minor street delay may be justified, such as channelization, widening, or signalization.

Level of Service
Consistency wph General Plan level-of-service policies for the proposed Project were determined based on the methods described above and identified as either "conforming" or "non- conforming". General Plan Policy M4.1.3 addresses level of seryice:

Strive to ochieve ot teosttrafflc Level of Service "D" (or better) for local streets and roadwaysthroughoutthe city.ln designing ffansportotion improvements, the City will prioritize use of smart technologies and innovative solutions thot maximize efficiencies and safety while minimizing the physical footprint. During the course of pton buildout, it may occur thot temporclly higher levels-of-service result where roodway improvements hove not been ddequdtely phased os development proceeds. However, this situotion will be minimized bosed on annual tolfic studies and monitaring programs.

For the purposes of this analysis, level-of-service is considered potentially non-conforming if implementation of the Pro.iect would result in any of the following:
r Cause an intersection in Folsom that currently operates (or is projected to operate) at level-of-service D or better to degrade to level-of-service E, or worse; r lncrease the average delay by five seconds or more at an intersection in Folsom that currently operates {or is projected to operate) at an unacceptable level-of-service E or F' Bicycle/Pedestria n/Transit Faci I ities
An impact is considered significant if implementation of the Project would:
o lnhibit the use of bicycle, pedestrian, or transit facilities; r Eliminate existing bicycle, pedestrian, or transit facilities; o prevent the implementation of planned bicycle, pedestrian, or transit facilities.

3.4 Vehicle Miles Traveled Standards of Significance
Under State Law (SB 7431, onJuly 1, 2020, vehicle miles traveled (VMT) will become the only metric for evaluating significant transportation impacts in environmental impact analyses required under the California Environmental Quality Act (CEQA). Without specific General Plan guidance for VMT thresholds, this analysis uses a qualitative screening against The Governors' Office of planning and Research (OPR) guidance of a !5016 per capita VMT reduction and utilizes OPR's suggested exemption for affordable housing proiects' Folsom General Plan policy NcR 3.1.3 addresses VMT, as stated below:
policy NCR 3.1.3 "Encourage efforts to reduce the amount of vehicle miles traveled (VMT).

These efforts could include encouraging mixed-use development promoting a jobslhousing balance, and encouraging alternative transportation such as walking, cycling, and public transit'"
OpR has published guidance recommending a CEQA threshold for transportation impacts of land use projects of a IS%VMT reduction per capita, relative to either city or regional averages fl IKEAR ',1, lrrW I i({}itf i na.CO iYl

based on the California's Climate Scoping Plans. Qualitative assessment of VMT reduction is acceptable to screen Projects6.

Based on these criteria, a project will be considered to have a potentially significant impact if:
o per capita VMT from residential proiects is anticipated to be greater than 85% of the regional average Per capita VMT'
r The project is anticipated to inhibit implementation of planned pedestrian, bicycle, or transit imProvements'

3.5 Analysis Tools
Llvel-of-S-ervice
Control delays and level-of-service for study intersections were calculated using the Synchro 117 analysis software (Version 11.1, build 1, revision 6). synchro implements the rnethodologies of the 6th Edition of the Highway Capacity Manualto modeltraffic controls and vehicle delay.

The software requires data on road characteristics (geometric), traffic counts, and the signal timing data for each analysis intersection. ln general, default parameters were used, except in locations where specific field data are available. Heavy vehicle percentaBes of 2% were assumed during the peak hour.

VMT
ro support jurisdictions' s8743 implementation, The Sacramento Area Council of GovernmentS (SACOG) staff developed thresholds and sffeening maps for residential and office projects, using outputs from the 2016 base year travel demand model run for the 2020 Metropolitan Transportation plan/Sustainable Communities Strategies (MTP/SCS)' SACOG travel demand model is activity/tour based and is designed to estimate an individual's daily travel, accounting for land use, transportation and demographics that influence peoples'travel behaviors.

For residential projects, the threshold is defined as total household VMT per capita achieving L5% ol reduction comparing to regional {or any appropriate sub-area} average' The SACOG screening map uses "hex" geography, with each hex being about 1000feet on edge' Residential VMT per capita per hex is calculated by tallying all household VMTs, including VMT traveling outside the region, generated by the residents living at the hex and divided by the total population in the hex. Hexes are then color coded with green and blue hexes depicting neighborhoods with at least a 15% reduction in residentialvMT relative to the sAcoc region, yellow, orange, pink and red hexes have less tha n a 15% VMT reduction' s OpR (2018) Technical Advisory on Evaluating Transportation lmpacts ln CEQA, b$pflwv/ts;ru

4.2 Assessment of ProPosed Project
Trip Generation
projected traffic generated by the proposed Project was calculated using trip generation factors from the lnstitute of Transportation Engineers (lTE) Trip Generation Manual, 1lth Edition (202L1, and is provided in Table 5 below.

Table 5. Project TriP Generation
Source: ITE (2021) Trip Generation Manual, lnstitute of Transportation Engineers, Washington DC (Higher value of either the average rate or the fitted eguation-based rate for peak hour of generator).

Trip Distribution
Trip distribution was based on observed traffic counts and select zone analysis within the travel demand model. New Project trips were distributed as follows:
c 48%tofirom the west on East Natoma Street
o 48% tofrom the east on East Natoma Street
o 4Yotoffrom the north via Prison Road
Project trip assignment is shown in Figure 9.

Signal Timing and Geometry
With the addition of a fourth leg to the East Natoma St/Prison Rd intersection, the signal timing and lane geometry was assumed to be configured as follows:
o Eastbound: An eastbound right turn pocket was assumed with 150-feet of storage and a 5o-foot taper; for a total of one left, one through, and one right turn lane. r Westbound: A westbound left turn lane with 100-foot pocket plus 5O-foot taper for a total of one left and one shared through-right lane.
r Southbound; The existing exclusive right-turn lane is assumed to be restriped as a through-right turn lane (for a total of one left and one shared through-right)' r Northbound: The northbound approach is assumed to provide one left and one shared through-right lane. The northbound through-right lane is assumed to be in a 70' turn pocket Plus 60'taPer.

62 second eastbound and westbound through phases. Crosswalks are assumed across all legs of the intersection with flashing don't walk phases set to 22 seconds to accommodate a 3 feet per seconding walking speed.

City staff have noted that the East Natoma St/Prison Rd intersection may be an excellent location for protected-permissive left-turn phasing {i.e., "a flashing yellow arrow" to allow left turns during the conflicting through phase). Such phasing would increase the intersection capacity and reduce queuing for the eastbound through movement. lt is our professional judgement that novel phasing plans, such as protected-permissive phasing, have the potentialto confuse elderly drivers and pedestrians, resulting in increased accident rates. Because protected-permissive phasing is not necessary to maintain the General Plan level-of-service goals we do not recommend it forthe entrance to age-restricted housing. The project adds a fourth leg to the existing T-intersection, which requires upgrading the traffic signal hardware. At the discretion of the City Engineer, those upgrades may include video vehicle detection, connecting the signal into the City traffic management centet and traffic signal controller upgrades to the satisfaction of the City Engineer' The eastern proiect driveway was assumed to be configured as right-in-right-out. Because there are fewer than ten peak,hour vehicle trips anticlpated to enter the Project via the eastern driveway, no deceleration lane or taper is necessary'

4.3 Existing 2022 with Proiect Conditions
project peak-hour traffic was added to the Existing 2022 turning volumes at each intersection.

Delay and level-of-service were determined at the study intersections. Figure 8 summarized the turning movements and lane configurations for the Existing with Proiect Condition. Table 7 presents a summary of level-of-service results for the study intersections under Existing Conditions. Allstudy intersectaons operate at level-of-service B or better during the AM, PM, and Sunday peak hours. Calcutation sheets for intersection delay and leveFof-service are provided in Appendix B, Left turn queues are adequately accommodated by the existing left turn storage pockets.

5, PROJECT VMT IMPACTS AND GENERAL PLAN LEVEL-OF-SERVICE

CONFORMITY

5.1 Vehicle Miles Traveled
Folsom General Plan policy NCR 3.1.3 addressed vehicle miles traveled (VMT) as shown below:
policy NCR 3.1.3 "Encourage efforts to reduce the amount of vehicle miles traveled (VMT).

These efforts could include encouraging mixed-use development promoting a jobs/housing balance, and, encouraging alternative transportation such as walking, cycling, and public transit."
The Governors' Office of Planning and Research (OPR) has published guidance recommending a CEQA threshold for transportation impacts of land use projects of a tSYo VMT reduction per capita, relative to either city or regional averages, based on the California's Climate Scoping Plane. Qualitative assessment of VMT reduction is acceptable to screen proiectslo.

Under State Law {SB 743), VMT became the only CEQA threshold of significance for transportation impacts on July t,2OZA. Without specific General Plan guidance for VMT thresholds, this analysis uses qualitative screening against OPR's guidance of a 15% per capita VMT reduction.

To support jurisdictions'SB743 implementation, SACOG developed thresholds and screening maps (Figure 10) for residential projectsll, using outputs from the 2016 base year travel demand model run for the 2020 MTP/SCS. SACOG's travel demand model is activity/tour based and is designed to estimate an individual's daily travel, accounting for land use, transportation and demographics that influence peoples'travel behaviors. For residential projects, the threshold is defined as total household VMT per capita achieving 15% of reduction compared to regional {or any appropriate sub-area) average VMT. The map uses HEX geography. Residential VMT per capita per HEX is calculated by tallying all household VMTs, including VMT traveling outside the region, generated by the residents living at the HEX and divided by the total population in the HEX.

6. OTHER CONSIDERATIONS

6.1 lnternal Ctrculation and Site Plan Review
This section reviews parking, driveway throat-depth, and emergency vehicle access shown on the preliminary site plan shown in Figure 2 (page 3).

Parking Requirements
The C1y does not have an adopted parking standard for age-restricted (senior) multi-family housing or affordable age-restricted multi-family housing. With a Planned Development (PD), parking supply is established through the PD permit process' proposed Project Parking: Proposed Parking consists of 135 spaces (1.00 parking spaces per unit). This exceeds that of many other recently approved age restricted multi-family projects in and around Folsom. The 135 spaces include 8 accessible spaces (i.e., with the adiacent space striped out to provide vehicle access for wheelchairs and/or mobility scooters) and 74 spaces with electric vehicle charging'
parklng Demand: The ITE Parking Generation Manuall2 lists an average peak parking demand of

0.59 vehicles per dwelling unit for Land Use 252 (Senior Adult Housing-Attached), with a standard deviation of g.!2.The ITE sample size is small (three obseruations), yet the proposed parking ratio of 1..00 is more than 3.5 standard deviations greater than the mean parking demand.

Consequently, the proposed parking for the Project is sufficient to meet the anticipated parking demand with a parking ratio of 1.00.

For comparison, Revel Senior Living, a similar project approved by Folsom in 2018 had a parking ratio of 0.81 spaces per dwelling unit. The Revel project conducted a parking survey of six similar Sagamento area facilities. All six facilities were found to use less than 0.60 spaces per dwelling unit during peak parking demand hours (consistent with the ITE parking demand data referenced above.)
Finding: The proposed parking supply of 136 spaces is adequate for the 136 multi-family units proposed in the Project.

M inimum Required Throat-DePth
Minimum Required Throat-Depth (MRTDI: For an 81-150 unit apartment complex, the standard forthe MRTD is 50 feet13. This So-foot length represents vehicle storage equivalents, which means the total required length may be achieved by summlng the throat depths for several access points if more than one access point is to serve the site.

Throat-Depth Provided: As shown on the preliminary site plan in Flgure 2 {page 3), the throat depths for the primary and second driveways exceed 50 feet and 25 feet, respectively. 12 ITE (2010) parking Generation 4th Edition, lnstitute of Transportation Engineers, Washington DC. 13 Folsom (2020) Design and Procedures Manual and lmprovement Standards, site access Table 12-1, !$CI:Jlttyy$rJs_bsaneJd6l{( Exl f ileb a n h/ blq, lrd! qa!!s-l@' S f nEnn wwwtkearrnc.com

03/28/2023 Item No.13.

Natoma Senior APartments Folsom,
CaliforniaTransportation lmoact Studv
Finding: The MRTD of the project driveways meet the standard because the primary drlveway throat depth meets the minimum standard of 50 feet'
Emergency Vehicle Access
The project,s internal drive isles are designed with minimum 25-foot inner and 50-foot turning radii to accommodate fire department access'
Finding: Emergency vehicle access is designed consistent with standards and is adequate.

6.2 Bicycle/Pedestrian/Transit Facilities
The project does not inhibit the use of bicycle or pedestrian facilities; eliminate existing bicycle, or pedestrian facilities; or prevent the implementation of planned bicycle, or pedestrian facilities. The project includes accessible pathways around the building to provide a walking path for residents. path connections are planned to paths internal to the Project site, south to the Oak parkway Trail, and west to the East Natoma St underpass to the Johnny Cash Trail.

Finding: The project has a less-than-significant impact on pedestrians and bicycles' With relocation of the effected bus stop, transit impacts will be less-than-signiflcant'

6.3 Queueing
Anticipated 9sth-percentile left turn queue lengths were reviewed and are anticipated to be less than the supplied storage lengths in the turn bays'
Finding: Existingturn pockets are adequate'
6,4 Driveway GeometrY
City standards requires a 60-foot right turn taper in conditions with ten or more peak-hour right turns into a driveway, and a 150-foot pocket plus 50-foot taper, with 50 or more peak-hour right turns. Neither project driveway is anticipated to have ten or more right turning vehicles into the project during the AM or PM peak-hours. The main driveway at the signalized East Natoma Street/prison Rd intersection includes an eastbound right turn pocket and a westbound left turn pocket accessing the Project, these are adequate to safely accommodate Project traffic without hindering existing traffic.

The secondary (eastern) driveway is restricted to right-in-right-out movements and is anticipated to only have fewer than ten eastbound right-turns into the Project during either the AM or PM peak hours. No turn pockets are necessary, The eastern driveway should be channelized to restrict left turns from entering or existing the Project via the eastern driveway. such channelization may be accomplished by either a triangular island located within the driveway, or by extending the raised median at the East Natoma st/cimmaron cir intersection west-word across the eastern Project drivewaY'
Finding: Drivewaygeometry has been determined to be adequate,leftturns atthe eastern Proiect driveway should be restricted through the use of channelization. 5l f fEnn w\ryw,tkearrnc'corn

6.5 Fire Lane and lnternal Geometry
The project proposes two access points connected by a fire lane which circles the back of the proposed apartments. All internal radii have at least a 25' inner radius and S0'outer radius per City requirements.

6.6 Accident History
potential geometric constraints and safety issues were evaluatedn including driveway spacing, sight triangles, and Statewide lntegrated Traffic Records System (SWITRS) collision data' Driveway spacing, throat depth, and corner sight distance are all adequate. ln the last five years, there have been three accidents proximate to the Project site including:
r One eastbound rear-end collection at the existing traffic light, r Two driving underthe influence (DUl) accidents (one a sideswipe, and the other a single vehicle overturn.)
These are not accident varieties that would be anticipated to be worsened by the Proiect, and the project does not require any project specific traffic safety treatments. r,,r\iirl/ lkei.j rr nc clf t5l rKEAR

7. FINDINGS, MITIGATION, AND RFCOMMENDED CONDITIONS
Finding 1 (Trip Generation|: The Project is anticipated to generate 441 daily vehicle trips including 39 AM peak-hour vehicle trips, and 41 PM peak-hour vehicle trips. Fewer than 50 peak-hour project trips are projected to pass through any intersection.

Finding 2 (Level-of-service): All study intersections are anticipated to operate at level-of-service B or better under all study scenarios. The Project is not projected to create new deficiencies or worsen existing traffic level-of-service, pursuant to General Plan Policy M4.1.3. lmpacts to level- of-service are considered less than significant'
Finding 3 {Vehicle Miles Traveledf : Per capita Project VMT is projected to be at least 15% less than regional per capita VMT. Project VMT impacts are considered less than significant.

Finding 4 (parkingl: The proposed parkinB supply of 136 spaces (1.00 spaces per unit). The Project was found to be adequately parked with either parking ratio.

Finding 5 (Minimum Required Throat Depth): The standards for driveway throat depths are met' Finding 5 (Emergency Vehicle Accessf : Emergency vehicle access is adequate.

Finding 7 (pedestrian and Bicycle): The Project does not result in impacts to pedestrian and bicycle facilities. lmpacts to pedestrian and bicycle facilities are considered less than significant.

Finding 8 (Transit): The ProJect does not result in impacts to transit facilities. lmpacts to transit facilities are considered less than significant'
Flnding 9 (Driveway Geometry): Proposed geometry for access to East Natoma St is adequate.

Either a raised median or right-turn channelization should be used to limit the secondary (eastern) driveway to right-in-right-out access. Note that the secondary {eastern) driveway was modeled assuming a shared eastbound through-right turn lane, without a right turn taper or deceleration lane. Anticipated eastbound right turning volume is less than 10 vehicles during the AM and PM peak-hours and neither a right tapper or deceleration lane is required per City of Folsom policy.

However, the City reserves the right to require either a taper or pocket at the discretion of the City Engineer,
Finding t0 (signal Timingl: With the addition of a fourth leg to the East Natoma St/Prison Rd intersection, the signal timing and lane geometry was assumed to be configured as follows:
r Eastbound: An eastbound right turn pocket was assumed with 150-feet of storage and a 60-foot taper; for a total of one left, one through, and one right turn lane. r Westbound: A westbound left turn lane with 100-foot pocket plus 60-foot taper for a total of one left and one shared through-right lane.
o Southbound: The existing exclusive right-turn lane is assumed to be restriped as a through-right turn lane {for a total of one left and one shared through-right). '.,llww lke.lrtt:c.cli'r5l rr<Ean

03/28/2023 Item No.13.

Natoma Senior APartments Folsom,
CaliforniaTransportati on lmoact Studv
r Northbound: The northbound approach is assumed to provide one left and one shared through-right lane. The northbound through-right lane is assumed to be in a 70'turn pocket Plus 50'taPer'
r Timing: Eastbound and westbound protected left turn phasing, northbound and southbound split phasing. 1.50 second cycle length, with 34 second northbound southbound split phases and 20 second eastbound and westbound protected phases, and 62 second eastbound and westbound through phases. Crosswalks are assumed across all legs of the intersection with flashing don't walk phases set to 22 seconds to accommodate a 3 feet per seconding walking speed.

City staff have noted that the East Natoma St/Prison Rd intersection may be an excellent location for protected-permissive left-turn phasing (i.e., "a flashing yellow arrow" to allow left turns during the conflicting through phase). Such phasing would increase the intersection capacity and reduce queuing for the eastbound through movement. lt is our professional judgement that novel phasing plans, such as protected-permissive phasing, have the potentlalto confuse elderly drlvers and pedestrians, resulting in increased accident rates. Because protected-permissive phasing is not necessary to maintain the General Plan level-of-service goals we do not recommend it for the entrance to age-restricted housing. The proiect adds a fourth leg to the existing T-intersection, which requires upgrading the trafflc signal hardware. At the discretion of the City Engineer, those upgrades may include video vehicle detection, connecting the signal into the City traffic management center, and traffic signal controller upgrades to the satisfaction of the City Engineer. \:( \'t Vi l\. {a, ; 1t \.' {:.C O r.SlIKEAR

The following memorandum summarizes the parking demand analysis that was conducted for the proposed affordable attached senior housing development in the City of Folsom, CA. City staff iroviOeA the following comment in response to the initial site plan application. . Parking: The submitted site plan indicates that l*5 on-site parking spaces are proposed for the 136-unit senior affordable living community (l:l parking ratio). The Folsom Municipal code does npt include any specific parking requirements with regard to senior affordable apartment communities. As a resul7 a iustification for the proposed parking ratio is requested (similar proiects?). As part of the parking analysi5 please provide information on the totalnumber of employees on the proiect site at any one time. Also, will employees have designated parking spaces? Project-specific parking standards for this development can be accommodated through the Planned Development Permit
Project Description
The proposed project is located in Folsom, CA and would include development of up to 136 afforiable attaihed senior housing units with up 136 on-sile parking stalls. The prolect is proposing to provide 98 1-bedroom units and 38 2-bedroom units and would employ 3.5 fulltime employees.

Parking Requirements
The Folsom Municipal Code does not include any specific parking requirements with regard to senior affordable apartment communities, As noted in the City comments, parking requirements are established through the Planned Development Permit process. The purpose of the following analysis is to establish a parking supply for the proposed project based on similar projects and demand rates published in the ITE Parking Generation Manual. previous proposed senior adult aftached housing developments in Folsom have proposed similar parking ratios to the current proposal.

VINTAGE SENIOR APARTMENTS

PARKING DEMAND CASE STUDY ANALVSIS
January ?,2023
Vintage Housing has requested their property management company, FPI Management, to perform case study of real time review of parking demand at seven existing Vintage owned Senior Apartment communities that dre similarly located in suburban settings. The seven senior properties/projects are as follows:

1. Vintage at Bouquet Canyon; Santa Clarita, CA
264 Units & 181 Parking Spaces (0.69 Spaces per Unit)
l-bedroom = 182 & 2-bedroom = 82; Total Bedroom = 345 (0.52 spaces per Bedroom) Z. Vintage atThe Crossings; Reno, NV
23O Units & 175 Parking Spaces {0.76 Spaces per Unit}
1-bedroom = 140 & 2-bedroom = 90; Total Bedroom = 320 (0.55 spaces per Bedroom)

3. Vintage at Sanctuary; Reno, NV
208 Units & 100 Parking Spaces {0'48 Spaces per Unit}
Studio = 3 & 1-bedroom = 205i Total Bedroom = 208 (0.48 spaces per Bedroom)

4. Vintage at Seven Hills; Reno NV
244 Units & 244 Parking Spaces {1'0 Spaces per Unit}
1-bedroom = 70 & 2-bedroom = 1.74; Total Bedroom = 418 {0.58 spaces per Bedroom)

5. Vintage at Bennett Valley; Santa Rosa CA
189 Units & 210 Parking Spaces (1'11Spaces per Unit)
1-bedroom = 125 & 2-bedroom = 54; Total Bedroom = 253 (0.83 spaces per Bedroom)

6. Vintage at NaPa; NaPa CA
115 Units & 52 Parking Spaces (0.54 Spaces per Unit)
1-bedroom = 109 & 2-bedroom = 5; Total Bedroom = 121 (0.51 spaces per Bedroom)

7. Seasons at Laguna; Elk Grove CA
222 Units & 158 Parking Spaces (0.71 Spaces per Unit)
1-bedroom = 150 & 2-bedroom =72;Tolal Bedroom = 294 (0.54 spaces per Bedroom) property Management (Fpl) has been managing all seven properties for many years and is acutely aware of all management items of the seven properties listed above. Based on historical experience the peak demand for parking typically takes place after 8 PM. Property Management (FPl) performed a parking countonthefollowingdatesof September Lg,2122,orNovember L4,zg2z,afterthe8PM hour' Property Management (Fpl) reviewed parking demand and the projects above and reported back on the following questions:
go unused?
Attached to this letter is property Management (FPl) summary findings of Parking Demand at each of the senior Apartment Projects listed above.

Based on review of the Data for each senior Apartment projecl vintage Housing findings are as follows:

03/28/2023 Item No.13.

1. Vintage at Bouquet Canyon; Santa Clarita, CA (0.59 stalls per unit/lO'52 spaces per Bedroom) fropit was noted to have an onsite parking supply issue, not based on parking stalls being provided, however City code requires that 33 spaces (18%) be reserved by guests' Guest parking ip..", at peak demand were going underutilized. FPI working with the City to allow for the use of tire guest parking spaces for overnight parking by residents. FPI ongoinS/continual efforts of collaborating with the City and assigning and enforcing parking rules and regulations parking is adequate with no on-street parking'

2. Vintage at The Crossings; Reno, NV (0.76 stalls per unit//0'55 spaces per Bedroom) project was noted to have no onsite parking supply issues. Based on counts 10-12 spaces go unused in the peak hours. However, it was noted on street parking is allowed and up to 4 residents choose to park on the street based on the proximity of the unit to on-street parking' FPI assigns parking and manages accordingly and FPI does not report any parking demand issues.

3. Vintage at sanctuary; Reno, NV (0.48 stalls per unit//0.48 spaces per Bedroom) f roject was noted to be experiencing a lack of onsite parking supply resulting in resident parking on the adjacent streets. On-Street parking is encouraged and allowed by the City in the zoning district. Fpl does report that onsite parking is assigned, and demand is high for these parking spaces, Through Fpl continual ongoing management and enforcement of parking, residents parking both onsite and/or on-street meets the demand of the project. FPI did note that all units in this project are either Studios or l-Bedroom units'

4. Vintage at seven Hills; Reno NV {1.0 stalls per unit//0'58 spaces per Bedroom) projeit was noted to have no onsite parking supply issues. FPI assigns parking and manages accordingly and FPI does report during peak hours most if not all the parking stalls are utilized.

Fpl did identify this Senior Apartment Community does have a relatively high 2-bedroom unit mix (7t%l and based on this FPI experience the 1- to 1 parking to unit ratio works fine based on the high 2-Bedroom count.
,

5. Vintage at Bennett valley; santa Rosa CA {1.11stalls per unit//0.83 spaces per Bedroom) eroject was noted to have no resident onsite parking supply issues and during peak demand there are several parking stalls not being utilized. FPI experience is that these routinely unused parking stalls do become a bit of a nuisance as these parking stalls tend to attract non-operable vehicles that are in violation of property management rules and in rare instances require towing' FPI did note at the main entry location periodic loading and unloading is an issue that is continually managed bY PropertY management.

5. Vintage at Napa; Napa, CA {0.54 Spaces per Unit //0.51 spaces per Bedroom} project was noted to be experiencing a lack of onsite parking supply' This is resulting in residentslvisitors parking on the adjacent local streets. FPI does report that onsite parking is assigned, and demand is extremely high for these parking spaces. Through FPI continual ongoing r",irg"r"nt and enforcement of onsite parking by residents, FPI is able to manage the parking demand of the project. FPt did note that this project has a relatively high 1-Bedroom count {95% units) and if there were more 2-Bedroom units parking would need to be restricted.

7. seasons at Laguna; Elk Grove, cA {0,71 Spaces per Unit /10.54 spaces per Bedroom) project *", not"d to be experiencing a lack of onsite parking supply resulting in resident parking on the adjacent streets. On-Street parking is currently being allowed by the city' FPI does report

03/28/2023 Item No.13.
that onsite parking is assigned, and demand is high for these parking spaces. Through FPI continual ongoing management and enforcement the parking of residents both onsite and on the street meets the demand of the project. FPI did note that this property has 2 large loading areas on both the west and east side of the and ownership/management discussions have taken place and studies would indicate that an additional 20 onsite parking spaces could be provided.

Vintage Housing review, including assistance from Property Management (FPl), of both historical experience and real time data provided for the seven Case Studies includes a relatively wide range of onsite parking allocation range from the lower end of 0.48 stalls/unit (0.48 stalls/bedroom) to t'tt stall/unit (0.83 stalls/bedroom). ln this review it was noted that any parking analysis should consider both the total number of units and the actual unit mix of l-Bedroom to 2-Bedrooms. ln this review the high percentage of 1-Bedrooms could suppon a lower demand for parking ratio and a high percentage of 2- Bedrooms yielded a higher demand parking ratio. Furthermore, based on zoning districts the City's desire for allowing on-street parking should be considered.

Based on both experience and data provided to determine adequate onsite parking is provided for residents/guests/employees, doing any analysis of parking based on total number of units could be misleading as parking demand for l-bedroom and 2-bedroom can vary widely. lnstead for the purpose of this analysis we used the number of bedrooms to analyze parking demand. Based on the Data provided the average parking to bedroom ratio was 0.57 parking spaces per unit. Vintage Housing upon review of this data inquired with Property Management (FPl) should a parking ratio of 0.60 spaces per bedroom be provided for each of the six projects listed would this resolve any onsite parking demand issues. Property Management {FPl) after performing an analysis of the potential increase in number of parking spaces for six of the seven properties Property Management (FPl) indicated that the additional parking spaces onsite would meet the demand for residents/8uest /employees'
The proposed Natoma Senior Apartments being a 136-unit Senior Residential Apartment {98 1-Bedroom (72%l and 38 2-Bedrooom (28%)) and providing 136 parking spaces at ration of 1-space/1-unit or 0'78 space/bedroom provides more than the 0.60 spaces per bedroom as analyzed above. Natoma Senior Apartment parking ratio provided of 0.78 spaces/bedroom will yield an onsite parking facility that should exceed the demand of the proposed Senior Apartment complex to included residents/guests/employees'

Vintage at Folsom Senior Apartments ISMND

1.0 INTRODUCIION
Vintage at Folsom, Lp (Applicant) proposes to develop the Vintage at Folsom Senior Apartments Project {proposed project), whictr includes construction and operation of a 135-unit, affordable senior (i.e., age- restricted) rental housing community on an estimated 4.86-acre site. The site is located at 103 East Natoma street, approximately 350-feet (ft) northeast of the intersection of Fargo Way and Natoma Street in the City of Folsom.

This lnitial Study addresses the proposed project and whether it may cause significant effects on the environment. These potential environmental effects are further evaluated to determine whether they were examined in the Folsom General Plan 2035 Environmental lmpact Report {ElR; 2018). ln particular, consistent with public Resources code (pRC) 521083.3, this lnitial study focuses on any effects on the environment which are specific to the proposed project, or to the parcels on which the project would be located, which were not analyzed as potentially significant effects in the General Plan ElR, or for which substantial new information shows that identified effects would be more significant than described in the previous ElRs. For additional information regarding the relationship between the proposed project and the previous ElRs, see Section 6 of this lnitial Study' The lnitial Study is also intended to assess whether any environmental effects of the project are susceptible to substantial reduction or avoidance by the choice of specific revisions in the project, by the impoiition of conditions, or by other means IS15152{bx2)l of the California Environmental Quality Act (C|OA) Guidelines. lf such revisions, conditions, or other means are identified, they will be identified as mitigation measures.

This tnitialstudy relies on CEQA Guidelines $15064 and 15064.4 in its determination of the significance of environmental effects. According to 515064, the finding as to whether a project may have one or more significant effects shall be based on substantial evidence in the record, and that controversy alone, without substantlal evidence of a significant effect, does not triSger the need for an ElR.

2.0 PROJECT BACKGROUND
The proposed proiect is comprised of Assessor Parcel Number (APN) 071-0320-042 in Sacramento County, California. The following proJect specific technical reports or surveys were used in preparation of this lnitial Study and are incorporated by reference:
r Biological Resources and Wetland Evaluation Letter Report by HELIX (October 2020)' e Cultural Resources Assessment by HELIX {March 2022}'

3.0 PROJECT DESCRIFTION

3.1 Profecl locqlion
The project site is located at 103 East Natoma Street, approximately 350-ft northeast of the intersection of Fargo Way and Natoma Street, in the City of Folsom (City) in Sacramento County, California. The project site is approximately 4.86-acres and is identified as Assessor's Parcel Number (APN) 071-0320- 042. The project site frontage is along East Natoma Street. The site is located within Rios de los Americanos Land Grant (Mount Diablo Base and Meridian, United States Geological Survey 7.5-minute "Folsom Quadrangle"). Refer to Figure l- for the Vicinity Map, Figure 2 for the Aerial Map, and Figure 3 for the Site Plan (Note: Allfigures are located in Appendix A). The property is owned by Vintage at Folsom, LP.

3.2 Projecl Settlng qnd Surroundlng lqnd Uses
The triangle shaped project site is currently vacant and undeveloped. The project site is considered to be blue oak woodland, surrounded by urban development. Historic aerial imagery shows that the project site has changed little since 1952 and habitat types/vegetation communities in the project site include blue oak woodland and ephemeral and intermittent drainages. The site is moderately disturbed.

There is evidence of recreational use by bicycles and the site has a constructed dirt track with several constructed dirt ramps and jumps for bicycles, presumably constructed by children from the adjacent residential neighborhood. lt also has debris piles and other evidence of use by transients. The terrain in the project site and vicinity is locally flat. The elevation on the project site ranges from 350- to 370-ft above mean sea level (amsl) and has low to moderate slope from east to west.

Folsom State Prison is located immediately north of the site, along Prison Road. East of the project site is single family homes along Cimmaron Circle, and south of the project site is Pacific Gas & Electric (PG&E) powerlines, single-family homes, and duplexes. West of the project, along Fargo Way, is office space and across from Fargo way is the Folsom City Police Department.

Neighboring land uses are summarized in Table 1.

the project site, with no traffic signal control. The main access driveway (36-ft) would wrap around the proposed building and connect with the additional egress/ingress point. The circulation driveway would range from 27- to 36-ft wide with parking spaces on either side. Turnarounds for emergency vehicle access would have an inner turning radius of 25-ft and an outer turning radius of 50-ft.

Oak parkway Trail, a Class I Bikeway, surrounds the proJect site. This biking trail would enter the southwestern corner of the site boundary. Within the site boundary, the Oak Parkway Trail would be realigned and connected to a concrete sidewalk proposed for the project. The conrete sidewalk would extend around the southern parking area and connect to the existing Oak Parkway Trail section located south of the site borindary. The realignment would add a pedestrian connection to the existing Oak parkway Trail. Additional proposed concrete sidewalks would be located at the frontage of the project site and would provide a sidewalk extension to Cimmaron Circle and would connect to internal sidewalks proposed around the building. These concrete sidewalks would provide walking paths for residents.

The proposed project would include 136 parking spaces in asphalt paved areas surrounding the proposed building. The parking supply includes 92 standard spaces {including 37 carport parking spaces), 10 compact parking stalls, 16 standard accessible stalls, four van accessible stalls, 12 standard electric vehicle charging station (EVCS) stalls, and two loading EVCS stalls. The electric vehicle charging spaces would be approximately 10.3 percent of the total parking spaces, which meets the electric vehicle charging station requirement outlined by CalGreen (Title 24, Part 11). Proposed parking is provided at a ratio of spaces per unit of 1:1.

The total parking area square feet excluding the carport areas would be 52,525-sf. The Folsom Municipal Code (FMC, Section t7.57 c (3) Planters, Landscaping) states that tree shall be interspersed through the parking area so that in 1,5 years,40 precent of the parking lot will be in shade at high noon. ln addition, the new California Green Code requires a project's parking lot area needs to provide 50 percent shade coverage within i.5 years. Within the project site. the totalshaded area would be 26,759-sf, which is approximately 50.9 percent of the total parking lot square footage, exceeding the minimum shade requirements of the Folsom Municipal code and the california Green code.

The applicant proposes a parking supply of 136 spaces to correspond to the development being age- restricted to seniors over 60 years of age and occupied with a population that typically has fewer drivers and a lower rate of vehicle ownership compared to conventional{family) multi-family communities, The reduced parking demand of age-restricted communities is also the result of reduced household sizes occupied by residents who no longer drive vehicles or who less frequently drive vehicles. Additionally' The Folsom Municipal Code does not address specific parking standards for senior residential uses.

Formerly approved senior apartments project (for both Market Rate and Affordable) have varied from

0.81 parking stalls per unit to 1.09 parking stalls per unit.

Additionally, the Folsom Municipal Code requires one bicycle parking space for every five residential units. With 136 residential units, the project requires 27 bicycle parking spaces. Bike racks would accommodate 28 bicycle parking spaces on the eastern side of the project site, east of the proposed building.

proposed utilities include domestic water, sewer utilities, fire service line and fire water main, primary anisecondary electricity lines, storm drain line, telephone/cable line, and gas line. Electrical, telephone/cable, and gas lines would be connected to existing facilities within the same vicinity of the project site, on East Natoma Street. All on site sewer utilities and water utilities (fire, domestic, and inigation) are to be privately owned, operated, maintained. All public water within the site boundary *orlU U" constructed in accordance with the City of Folsom water design standards and water construction details as a condition of approval. On-site water supply would be connected to the Zone 3 Cimmaron pressure zone located off-site, On-site sewer utilities would connect with a publicly owned sewer collection system off-site. Proposed fire hydrants are located throughout the project site. Along the frontage of the site, a 1.2.5-ft public utility easement would be installed for overhead or u nderground facilities.

3.3.3. SustqinqbilltY Feolures
The project design incorporates sustainable features consistent with General Plan Goal LU 9'1 and the California Green Building Standards Code (CalGreen). The project would exceed the 2019 California Building Energy Efficiency Standards {Title 24, Part 5) by 15 percent or more. The project provides 10 percenielectiic vehicle parking spaces (14), which is consistent with CalGreen standards. Cool paving features would be incorporated in the project site such as shade trees (39'3 percent), sidewalks/patios (24.9 percent), and parking stall/trash apron (4 percent), for a total reduction of 58'2 percent' This exceeds the minimum 50 percent reduction of nonroof heat islands on the project site, A cool roof would be installed per CalGreen/California Building Code (CBC) and a solar array is proposed for the asym metrical, gabled rooft oPs'

3.3.4. Irosh/RecYcling
A City standard trash enclosure would be enclosed with a trellis cover. The trash enclosure would have refused bins for recyclables, organics, and general waste. The trash enclosure would be located in the southeastern corner of ttre project site. Additionally, a trash room would be located on the ground floor of the proposed apartment building.

3.3.5. Fencing ond Signoge
An g-ft masonry wall is proposed on the eastern side of the project site, behind the single-family residences. The masonry wall would tie into an existing wood fence that runs along the eastern boundary line. A 6-ft-tall monument sign would be placed adjacent to the main access driveway, along East Natoma Street.

3.3.6. Amenllles qnd LondscqPing
Community amenities would include an estimated 2,500-sf community center on the ground floor, as well as a game room, a library room, exercise room and a craft room' Additional amenities on the project site would include outdoor seating and dining areas, perimeter walkways, a bocce ball court, bike racks, picnic tables with umbrellas, outdoor barbeques/ kitchens, and 6-ft benches. The project is 5

located just over one mile to East Bidwell and the Historic Folsom District which offers a variety of shopping centers, mercantile services, restaurants, state parks, and Light Rail Transit Access.

Landscaping would be designed to complement the buildings and make a positive contribution to the overall aesthetic of the site. The project would preserve key open space areas, including existing Oak Groves and portions of perennial creeks, through an interactive landscape design process. Within the property site,30-to 35-ft diameter shade trees, 25-ft diameter shade trees, accent trees, screen shrubs, foundation shrubs, accent shrubs, groundcovers, and bio infiltration species would be planted. Under existing conditions, the runoff from residential properties located east of the property flows onto the property site. This offsite runoff would be intercepted by proposed landscaped swales within 15-ft landscape planters along the eastern boundary of the property. This runoff would then be redirected towards East Natoma Street and would enter the public storm drain system. Additionally, eight bio- retention planters are proposed throughout the project site to manage stormwater runoff'

3.4 Conslrucllon ond Phoslng
The project would be graded and constructed in a single phase. Construction would likely begin in spring 2023 and would take approximately 18 months to complete'

3.5 City Regulolion of Urbqn Developmenl

3.5.1. General Plqn
The site is designated as professionalOffice (Po) in the Folsom 2035 General Plan' The Po designation provides for low-intensity business and professional offices that are compatible with higher-intenslty residential uses.

3.5.2. Zoning Ordinqnce
The zoning designation of the site is in the Business and Professional (BP) District. According to Section L7.Z1.3eof the Folsom MunicipalCode, the BP zoning district generally permits office building and related uses such as banks, doctor's offices, general business office, and general uses, The purpose ofa Bp zoning district is to provide an area for business and professional office and compatible related uses.

This zoning district is intended to promote a harmonious development of business and professional office areas with adjacent commercial or residential development. However, Senior citizens (Age 55+) residential complexes are considered a permitted land use within the BP zoning district upon approvalof a Conditional Use permit by the Planning Commission according to FMC Section 77.22'O3OE\' Entitlement requests for this project include a Planned Development Permit (PD) Permit and a Conditional Use permit. The purpose of the PD Permit is to allow for greater flexibility in the design of integrated developments than otherwise possible through strict application of land use regulations.

Wittr the pD permit, the project's site plan, elevations, and overall project desiSn would be evaluated, and specific development standards would be defined. A Conditional Use Permit is required to allow for development of senior apartments on the project site based on the BP PD zoning designation. 6

6.0 PREVIOUS RETEVANT ENVIRONMENTAL ANALYSIS

6.t Clty of Folsom Generol Plqn
The program EIR for the City of Folsom General Plan (2018) provides relevant policy guidance for this environmental analysis, The EIR evaluated the environmental impacts that could result from implementation of the city of Folsom 2035 General Plan (2035 General Plan) (city of Folsom 2018a)' The program EIR is intended to provide information to the public and to decision makers regarding the potential effects of adoption and implementation of the 2035 General Plan, which consists of a comprehensive update of Folsom's current General Plan. The 2035 General Plan consists of a policy document, including Land Use and Circulation Diagrams'

6.2 Tlering
,,Tiering,, refers to the relationship between a program-level EIR (where long-range programmatic cumulative impacts are the focus of the environmental analysis) and subsequent environmental analyses such as the subject document, which focus primarily on issues unique to a smaller project within the larger program or plan. Through tiering a subsequent environmental analysis can incorporate, by reference, discussion that summarizes general environmental data found in the program EIR that establishes cumulative impacts and mitigation measures, the planning context, and/or the regulatory background, These broad-based issues need not be reevaluated subsequently, having been previously identified and evaluated at the program stage'
Tiering focuses the environmental review on the project-specific significant effects that were not examined in the prior environmental review, or that are susceptible to substantial reduction or avoidance by specific revisions in the project, by the imposition of conditions or by other means. Section 21093tb) of the public Resources code requires the tiering of environmental review whenever feasible, as determined bY the Lead AgencY.
ln the case of the proposed project, this lnitial Study tiers from the EIR for the Broadstone Unit No' 3 specific plan, and the EIR for the city of Folsom General Plan. The Folsom General Plan, as amended, is a project that is related to the proposed project and, pursuant to $15152{a) of the CEQA Guidelines, tiering of environmental documents is appropriate. CEQA Guidelines 515152{e} specifically provides that:

8.0 ENVIRONMENTAT INITIAL STUDY CHECKLIST
The lead agency has defined the cotumn headings in the environmental checklist as follows:

A. ,,potentially Significant lmpact" is appropriate if there is substantial evidence that an effect may be significant even with the incorporation of mitiSation. lf there are one or more "Potentially Significant lmpact" entries when the determination is made, dn EIR is required, B. ,,Less Than Significant with Mitigation lncorporated" applies where the inclusion of mitigation measures has reduced an effect from "Potentially Significant lmpact" to a "Less Than Significant lmpact." All mitigation measures are described, including a brief explanation of how the measures reduce the effect to a less than significant level. Mitigation measures from earlier analyses may be cross-referenced.

C. ,,Less Than Significant lmpact" applies where the project does not create an impact that exceeds a stated significance threshold.

D. ,,No lmpact" applies where a project does not create an impact in that cate8ory. "No lmpact" answers do not require an explanation if they are adequately supported by the information sources cited by the lead agency which show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No lmpact" answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project would not expose sensitive receptors to pollutants, based on a project specific screening analYsis).

The explanation of each issue identifies the significance criteria or threshold used to evaluate each question; and the mitigation measure identified, if any, to reduce the impact to less than significance.

Earlier analyses may be used where, pursuant to the tiering, program ElR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration ICEQA Guidelines Section 15063(cx3xD)1. where appropriate, the discussion identifies the following:
a) Earlier Analyses Used. ldentifies where earlier analyses are available for review. b) tmpacts Adequately Addressed. ldentifies which effects from the checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and states whether such effects were addressed by mitigation measures based on the earlier analysis.
c) Mitigation Measures. For effects that are "Less Than Significant with Mitigation lncorporated," describes the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project' l-5

Environmenlol Setting
The 4.g6-acre parcel proposed for development is currently vacant and undeveloped. Folsom State prison is located immediately north of the site, along Prison Road. East of the project site is single family homes along Cimmaron Circle, and south of the project site is Pacific Gas & Electric (PG&E) utility powerlines, single-family homes, and duplexes' West of the project, along Fargo Way, is office space and across from Fargo Way is the folsom City Police Department. Oak Parkway Trail is located west and south of the site, and Johnny Cash Recreation Trail is located north of the project site. The local setting is characterized by commercial development to the south and west, residential to the east and south, and institutionalto the north. Existing utility lines are located along East Natoma Street and south of the project site.

Evqluolion of Aeslhetics
a) Have a substantial adverse effect on a scenic vista? No impact. Neither the project site nor the surrounding areas are scenic vistas due to the existing nearby commercial, residential developments. Further, neither the project site, nor views to or from the project site, have been designated as important scenic resources by the City or any other public agency' Therefore, the proposed development would not interfere with or degrade a scenic vista, and no impact would occur.

b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?
No impact. The project site is currently vacant and undeveloped. The nearest officially designated state scenic highway is the segment of US Highway 50 from Placerville to Echo Summit, approximately 20 miles east (CalTrans ZOtg). Therefore, the project would not impact scenic resources, such as trees, rock outcroppings or historic buildings within a state scenic highway, and no impact would occur. ln non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). lf the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? Less than significant impact. The proposed project is located within an urbanized area of Folsom, surrounded by commercialand residential development and institutional land. The site is vacant and undeveloped, and the existing character of the site would be modified by the proposed development' The proposed project would construct a 136-unit affordable senior housing development, as well as proposed parting (bicycle and vehicle), landscape, and outdoor and indoor amenities' The apartment building roof height is 34-ft, with architectural elements ranging from 42-ft,5-inches to up to 42-ft' 6' inches above grade, and would be designed with stucco, board and batten, brick veneer, asphalt shingles, and wrought iron railing. The building would be visually compatible with the proposed landicaping throughout the project site. Please refer to Figure 4, Figure 5, Figure 5, and Figure 7 for architectu ral renderings of the proposed project site viewed from Natoma Street and the bike trail' ln order to accommodate for the change in existing character, the proposed project would implement landscape screening, site amenities, and building designs to blend the proposed project with surrounding development and screen the project from residential neighbors' Along the proposed 8-ft masonry *tll on the eaStern boundary, shade, and accent trees, as well aS several evergreen SpecieS would be planted as landscape screening. The landscape screening would be planted in order to block the sightline of homes along Cimmaron Circle and surrounding streets from the third story of the proposed building. tree heilht would range from 15- to 35-ft based on tree type and would supplement ihe existing trees in the neighboring yards. Please refer to Figure 8 and Figure 9 for architectural renderings of the proposed sightline screening. Additionally, landscaped areas with various trees and shrubs would surround the proposed building and parking area, and a bocce ball court, and outdoor seating areas would be included to add to the overall visual aesthetic. The proposed br;ilding would have asymmetricalgabled roofs to add visual interest'
The proposed proJect is consistent with types of uses envisioned and permitted in the Folsom General plan. The project is consistent with the BP zoning distric{ development standards and would be designed consistent with the City's Design Guidelines for Senior Housing Development' Entitlement requests for this project include a pianned Development permit (PD Permit) and a conditional use Permit (CUP). The Conditional Use permit is required to allow for development of a senior residential apartment community on the project site. The proposed land use is consistent with the overall suburban character and ongoing development in the vicinity and is expected to integrate into the existing and planned development of the area. The proposed project would have a less than significant impact on visual character and no mitigation is necessary.

d) create a new source of substantial light or glare that would adversely affect day or nighttime views in the area?
Less than significant impact. The project includes a combination of free-standing, pole-mounted parking lot and walkway lights, recessed carport and elevator lights, and building-mounted lights. To minimize potential lighting-related impacts, free-standing parking lot lights and recessed carport lights would be screened, shielded, and directed downward to minimize glare towards the surrounding properties. New lighting installed with the development of the proposed project would be subject to City standard practices regarding night lighting that would be made a condition of approval of the PD Permit. The proposed units and other project features would comply with design standards outlined in the Folsom irlunicipal Code. The exterior of the proposed apartment buildings would be designed with architectural detailing that would not produce glare and would not affect day or nighttime views, and existing City standards would limit light spillover and intensity. Therefore, impacts would be less than significant, and no mltigation is necessary.

Environmenlol Setting
Climate in the Folsom area is characterized by hot, dry summers and cool, rainy winters, During summe/s longer daylight hours, plentifulsunshine provides the energy needed to fuel photochemical reactions between oxides of nitrogen (NOx) and reactive organic gases (ROG), which result in ozone (Or) formation. High concentrations of Os are reached in the Folsom area due to intense heat, strong and low morning inversions, greatly restricted vertical mixing during the day, and daytime subsidence that strengthens the inversion layer. The greatest pollution problem in the Folsom area is from NOx.

The City of Folsom lies within the eastern edge of the Sacramento Valley Air Basin (SVAB). The Sacramento Metropolitan Air Quality Management District (SMAQMD) is responsible for implementing emissions standards and other requirements of federal and state laws in the project area. As required by the California Clean Air Act (CCAA), SMAQMD has published various air quality planning documents as discussed below to address requirements to bring the District into compliance with the federal and state ambient air quality standards. The Air Quality Attainment Plans are incorporated into the State lmplementation Plan (SlP), which is subsequently submitted to the U.5. Environmental Protection Agency {USEPA}, the federal agency that administrates the Federal Clean Air Act of 1970, as amended in 1990.

Ambient air quality is described in terms of compliance with state and national standards, and the levels of air pollutant concentrations considered safe, to protect the public health and welfare. These standards are designed to protect people most sensitive to respiratory distress, such as people with asthma, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. The USEPA has established national ambient air quality standards (NAAAS) for seven air pollution constituents. As permitted by the Clean Air Act, California has adopted more stringent air emissions standards {California Ambient Air Quality Standards [CMQS]) and expanded the number of regulated air constituents.

The California Air Resources Board (CARB) is required to designate areas of the state as attainment, nonattainment, or unclassified for any state standard. An "attainment" designation for an area signifies that pollutant concentrations do not violate the standard for that pollutant in that area. A "nonattainment" designation indicates that a pollutant concentration violated the standard at least once. The air qualiry attainment status of the SVAB, including the City of Folsom, is shown in Table 4.

Sacramento County is designated as nonattainment for the state and federal ozone standards, the state PMro standards, and the federal PMz.s standards. Concentrations of all other pollutants meet state and federal standards.

Ozone is not emitted directly into the environment, but is generated from complex chemical reactions between ROG, or non-methane hydrocarbons, and NOx that occur in the presence of sunlight. ROG and NOx f,enerators in Sacramento County include motor vehicles, recreational boats, other transportation sources, and industrial processes. PMro and PMz.s arise from a variety of sources, including road dust, diesel exhaust, fuel combustion, tire and brake wear, construction operations, and windblown dust.

Toxic Air Gonlqmlnontg
Toxic air contaminants (TAC) are a diverse group of air pollutants that may cause or contribute to an increase in deaths or in serious illness or that may pose a present or potential hazard to human health.

TACs can cause long-term chronic health effects such as cancer, binh defects, neurological damage, asthma, bronchitis, or genetic damage, or short-term acute effects such as eye watering, respiratory irritation (a cough), runny nose, throat pain, and headaches, TACs are considered either carcinogenic or State of Cellfornla

noncarcinogenic based on the nature of the health effects associated with exposure to the pollutant, For carcinogenic TACs, there is no level of exposure that is considered safe and impacts are evaluated in terms of overall relative risk expressed as excess cancer cases per one million exposed individuals.

Noncarcinogenic TACs differ in that there is generally assumed to be a safe level of exposure below which no negative health impact is believed to occur, These levels are determined on a pollutant-by- pollutant basis.

The Health and Safety Code (939655[a]) defines TAC as "an air pollutant which may cause or contribute to an increase in mortality or in serious illness, or which may pose a present or potential hazard to human health." All substances that are listed as hazardous air pollutants pursuant to subsection (b) of Section 112 ofthe CAA (42 United States Code Sec. 7a12[b]) are designated as TACs. Under State law, the California Environmental Protection Agency {CalEPA}, acting through CARB, is authorized to identify a substance as a TAC if it determines the substance is an air pollutant that may cause or contribute to an increase in mortality or an increase in serious illness, or that may pose a present or potential hazard to human health.

Diesel engines emit a complex mixture of air pollutants, including both gaseous and solid material, The solid material in diesel exhaust is referred to as diesel particulate matter {DPM}. Almost all DPM is L0 microns or less in diameter, and 90 percent of DPM is less than 2.5 microns in diameter (CARB 2022).

Because of their extremely smallsize, these particles can be inhaled and eventually trapped in the bronchiai and alveolar regions of the lung. ln 1998, CARB identified DPM as a TAC based on published evidence of a relationship between diesel exhaust exposure and lung cancer and other adverse health effects. DPM has a notable effect on California's population-it is estimated that about 70 percent of total known cancer risk related to air toxics in California is attributable to DPM {CARB 2022).

Sensillve Receptors
Some land uses are considered more sensitive to air pollution than others due to the types of population groups or activities involved and are referred to as sensitive receptors. Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB and the Office of Environmental Health Hazard Assessment (OEHHA) have identified the following groups of individuals as the most likely to be affected by air pollution:the elderly over 65, children under 14, infants (including in utero in the thlrd trimester of pregnancy), and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis (CARB 2005; OEHHA 2015).

Residential areas are considered sensitive receptors to air pollution because residents {including children and the elderly) tend to be at home for extended periods of time, resulting in sustained exposure to any pollutants present. Children and infants are considered more susceptible to health effects of air pollution due to their immature immune systems, developing organs, and higher breathing rates. As such, schools are also considered sensitive receptors, as children are present for extended durations and engage in regular outdoor activities'
The closest existing sensitive receptors to the project site are the single-family residences that border the project site to the east and the single-family residences located approximately 100-ft south of the project site. Additionally, Vibra Hospital of Sacramento is located approximately 350-ft south of the project site. The closest schools to the project site are Theodore Judah Elementary School and Blanche Sprentz Elementary School, located approximately 1,400-ft to the southwest and 2,000-ft to the southeast, respectively.

Melhodology snd AstumPlions
Criteria pollutant, precursor, and GHG emissions for project construction and operation were estimated using the California Emissions Estimator Model {CalEEMod}, Version 2O2A.4.O. CalEEMod is a statewide land use emissions computer model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify potential criteria pollutant and GHG emissions associated with both construction and operations from a variety of land use projects. The model was developed for the California Air Pollution Control Officers Association (CAPCOA) in collaboration with the California air districts. CalEEMod allows for the use of default data (e'g., emission factors, trip lengths, meteorology, source inventory) provided by the various California air districts to account for local requirements and conditions, and/or user-defined inputs. The calculation methodology and default data used in the model are available in the CalEEMod User's Guide, Appendices A, D, and E (CAPCOA 2021). The CalEEMod output files are included in Attachment A to this letter.

Construction of the project is anticipated to begin as early as January 2A23 and be completed in April 2024. Construction modeling assumes the fotlowing anticipated schedule: site preparation 10 working days; grading 87 working days; building construction 207 working days; paving 2l working days; and architectural coating 22 working days. Construction equipment assumptions were based on estimates from calEEMod defaults. The project would not require an import or export of soil during construction activities. Construction emissions modeling assumes implementation of basic dust control practices (watering exposed areas twice per day)to comply with the requirements of: SMAQMD Rule 403, Fugitive Dust.

Operational mobile emissions were modeled using the project trip generation of 441 average daily trips from the project Transportation lmpact Study (T. Kear Transportation Planning and Management, lnc. 2O2Zl. Operational emissions resulting from energy use, water use, and solid waste generation were modeled using calEEMod defaults with an added 20 percent reduction in water use to account forthe requirementr of tt "
2019 CALGreen, and an additional 25 percent solid waste diversion to account for AB 341 requirements.

Stqndqrds ol Slgniflconce
While the final determination of whether or not a project has a signifiiant effect is within the purview of the lead agency pursuant to CEQA Guidelines Section 15064(b), SMAQMD recommends that its air pollution thresholds be used to determine the significance of project emissions. The criteria pollutant thresholds and various assessment recommendations are contained in SMAQMD's Guide to Air QuoliV Assessrnenf in Sacrsmento County (CEQA Guide; 2020, revised), and are discussed under the checklist questions below.

Evoluollon of Ah QuolltY
a) Conflict with or obstruct implementation of the applicable air quality plan? Less than Significant lmpact. ln accordance with SMAQMD's Guide, construction-generated NOX, PM10, and pM2.5, and operational-generated ROG and NOX (all ozone precursors) are used to determine consistency with the Ozone Attainment Plan. The Guide states:
22

VintaSe at Folsom Senior Apartments ISMND
8y exceeding the District's mass emission thresholds for operotional emissions of ROG, NOX, PM70, or PM2.5, the Woject woutd be considered to conflictwith or obstruct implementotion of the District's air quolity planning efforts.

As shown in the discussion for question 2) below, the project's construction-generated emissions of NOx, PMro, and PMz.sand operation-generated emissions ROG and NOx would not exceed SMAQMD thresholds. The project would not conflict with or obstruct implementation of the applicable air quality plan and the impact would be less than significant. b) Result in a cumulatively considerable net increase of any criteria pqllutant for which the projed region is non- attainment under an applicable federal or state ambient air quality standard? Less than Significant lmpact. The Sacramento region is in non-attainment for ozone {ozone precursors NOx and ROG) and particulate matter (PMz.s and PMro). The project's emissions of these criteria pollutants and precursors during construction and operation are evaluated below.

Construction Em issions
Ca|EEMod version 2O2O.4.0 was used to quantifo project-generated construction emissions. The model output sheets are included in Attachment A. Construction activities were assumed to commence as early as January 2A23 and be completed in April 2O24.The quantity, duration, and intensity of construction activity inftuence the amount of construction emissions and related pollutant concentrations that occur at any one time. As such, the emission forecasts provided herein reflect a specific set of conservative assumptions based on the expected construction scenario wherein a relatively large amount of construction activity is occurring in a relatively intensive manner. Because of this conservative assumption, actual emissions could be less than those forecasted. lf construction is delayed or occurs over a longer time period, emissions could be reduced because of {L) a more modern and cleaner- burning construction equipment fleet mix than assumed in CalEEMo d; andlor (2) a less intensive buildout schedule (i.e., fewer daily emissions occurring over a longer time interva[).

The project's construction period emissions of ROG, NOx, PMro, and PMz.s are compared to the SMAQMD construction thresholds in Table 5. The SMAQMD does not have a recommended threshold for construction-generated ROG. However, quantification and disclosure of ROG emissions is recommended. The SMAQMD considers any emissions of PMro and PMz.r to be significant unless the Basic Construction Emissions Control Practices are implemented, also known as Best Management Practices (BMPs). The project would implement the SMAQMD BMPs to control fugitive dust in accordance with SMAQMD Rule 403. The modeling accounts for emissions reductions resulting from watering exposed surfaces twice daily. As shown in Table 5, the proposed project's construction period emissions of the ozone precursor NOx, PM1s, and PMz.swould not exceed the SMAQMD thresholds. lmpacts related to construction-generated emissions of ROG, NOx, PM19, and PMz.swould be less than significant.

As shown in Table 5 and Table 5, the project's maximum daily construction or operational emissions would not exceed the SMAQMD's thresholds. Therefore, the project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment, and the impact would be less than significant.
c) Expose sensitive receptors to substantial pollutant concentrations? Less than Significant lmpact. CARB and OEHHA have identified the following groups of individuals as the most likely to be affected by air pollution: the eldedy over 65, children under 14, infants (including in utero in the third trimester of pregnanry), and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis (CARB 2005, OEHHA 2015). Some land uses are considered more sensitive to air pollution than others due to the types of population groups or activities involved and are referred to as sensitive receptor locations. Examples of these sensitive receptor locations are residences, schools, hospitals, and daycare centers.

The closest existing sensitive receptors to the project site are the single-family residences that border the project site to the east and the single-family residences located approximately 100-ft south of the project site. Additionally, Vibra Hospital of Sacramento is located approximately 350-ft south of the project site. The closest schools to the project site are Theodore Judah Elementary School and Elanche Sprentz Elementary School, located approximately 1,400-ft to the southwest and 2,000-ft to the southeast, respectively.

The dose {of TAC) to which receptors are exposed is the primary factor used to determine health risk.

Dose is a function of the concentration of a substance in the environment and the extent of exposure a person has with the substance; a longer exposure period to a fixed quantity of emissions would result in higher health risks. Current models and methodologies for conducting cancer health risk assessments are associated with longer-term exposure periods (typically 30 years for individual residents based on guidance from OEHHAland are best suited for evaluation of long duration TAC emissions with predictable schedules and locations. These assessment models and methodologies do not correlate well with the temporary and highly variable nature of construction activities. Cancer potency factors are based on animal lifetime studies or worker studies where there is long-term exposure to the carcinogenic agent. There is considerable uncertainty in trying to evaluate the cancer risk from projects that will only last a smallfraction of a lifetime {OEHHA 2015). ln addition, concentrations of mobile source DPM emissions disperse rapidly and are typically reduced by 70 percent at approximately 500-ft (CARB 2005). Considering this information, the highly dispersive nature of DPM, and the fact that construction activities would occur at various locations throughout the project site, it is not anticipated that construction of the project would expose sensitive receptors to substantial DPM concentrations.

According to the SMAQMD, land use development projects do not typically have the potentialto result in localized concentrations of criteria air pollutants that expose sensitive receptors to substantial pollutant concentrations. This is because criteria air pollutants are predominantly generated in the form of mobile-source exhaust from vehicle trips associated with the land use development project. These vehicle trips occur throughout a paved network of roads, and, therefore, associated exhaust emissions of criteria air pollutants are not generated in a single location where high concentrations could be formed (SMAQMD 2020). Therefore, localized concentration of CO from exhaust emissions, or "CA hotspots," would only be a concern on high-volume roadways where vertical and/or horizontal mixing is substantially limited, such as tunnels or below grade highways. There are no high-volume roadways in the region with limited mixing that would be affected by project generated traffic. Once operational, the 25

03/28/2023 Item No.13.

project would not be a significant source of TACs. Therefore, the project would not expose sensitive receptors to substantial pollutant concentrations, and the impact would be less than significant. d) Result in other emissions {such as those leading to odors) adversely affecting a substantial number of people?
Less than Significant lmpact. The project could produce odors during construction activities resulting from heavy diesel equipment exhaust and VOC released during application of asphalt. The odor of these emissions is objectionable to some; however, emissions would disperse rapidly from the project site and therefore should not be at a levelthat would affect a substantial number of people. Any odors emitted during construction activities would be temporary, short-term, and intermittent in nature, and would cease upon the facility maintenance. As a result, impacts associated with temporary odors during construction are not considered significant.

As an affordable senior rental housing development, operation of the project would not result in odors affecting a substantial number of people. Solid waste generated by the proJect would be collected by a contracted waste hauler, ensuring that any odors resulting from on-site waste would be managed and collected in a manner to prevent the proliferation of odors. The project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people, and the impact would be less than significant.

The entire project site is considered to be blue oak woodland, surrounded by urban development.

Historic aerial imagery shows that the project site has changed little since 1952 and has consisted of oak woodland with a drainage running through the site. The site is moderately disturbed. There is evidence of recreational use by bicycles and the site has a constructed dirt track with several constructed dirt ramps and jumps for bicycles, presumably constructed by kids from the adjacent residential neighborhood, lt also has debris piles and other evidence of use by transients.

Studies conducted in support of the BRE included a special-status species evaluation, an aquatic resources evaluation, and a biological and wetlands reconnaissance survey. An Arborist Report was also concluded.

Specicl-Stotus Specles Evoluolion
For the purposes of the BRE, special-status species are those that fall into one or more of the following categories:

Listed as endangered or threatened under the Federal Endangered Species Act of 1973 (FESA), including candidate species and species proposed for listing; Listed as endangered orthreatened underthe California Endangered Specles Act (CESA), including candidate species and species proposed for listing; Designated as a Species of Special Concern {SSC} or watch-list {WL) species by the California Department of Fish and Wildlife (CDFW), or "Fully Protected" under the California Fish and Game Code {FP), or a sensitive natural community; andlor, Designated by the Catifornia Native Plant Society (CNPS) as California Rare Plant Rank 1A, LB,2A, 28, or 3.
ln order to evaluate special-status species and/or their habitats with the potentialto occur in the project site and/or be impacted by the proposed project, HELIX obtained lists of special-status species known to occur andfor having the potential to occur on the proposed project site and vicinity from the U.S. Fish and Wildlife Seruice (USFWS; USFWS 2020), the California Native Plant Society (CNPS; CNPS 2020), and the California Natural Diversity Database {CNDDB; CDFW 2020), which are included as Appendix D, The potentialfor these regionally occurring special-status species to occur in the project site is analyzed in Appendix D.

A biologicaland wetlands reconnaissance survey was conducted on September 30, 2020 by HELIX principal Biologist Stephen Stringer, M.S. and HELIX Biologist Stephanie Mclaughlin, M.S. between 0830 and 1400 hours. The project site was assessed to identify the habitat type(s) present on-site and the potential to support special-status plant and wildlife species. The survey consisted of a pedestrian survey of the proiect site and the surrounding area. Meandering transects of the site were performed to obtain visual coverage of the site. Plant species were identified to the level necessary to determine whether or not they were a special-status species'
The three-parameter method was used to determine the presence/absence of wetlands, which involves identifying indicators of hydrophytic vegetation, hydric soils, and wetland hydrology according to the Corps of Engineers Wetlands Delineation Monual (USACE 1987l,lhe Regional Supplement to the Corps of Engineers Wettand Delineation Manual: Arid West Region (Version 2.0; USACE 2008), A Field 6uide to the tdentification of the Ordinary High Woter Mork (OHWM) in the Arid West Region of the Western united States (Lichvar and McColley 2008) and the Sfote Wetlond Definition ond Procedures for Discharges af Dredged or Fil! Materialto Wqters of the State prepared by the State Water Resources Control Board and which became effective May 28, 2020. The presence/absence of other non-wetland aquatic resources was determined by searching for the presence of an ordinary high water mark and bed and bank. The extent of waters on the project site were mapped in the field with sub-meter accuracy using a Trimble GeoXT Global Positioning System (GPS) hand-held unit. The GPS data were downloaded from the unit, exported into ArcMap 10.7.10, and used to produce the map of aquatic features in the delineation area and to calculate the acreage of each aquaticfeature, Weather during the survey was clear and warm and hazy conditions. A complete list of plant and animal species observed on the project site during the biological reconnaissance survey is included in Appendix D.

The arborist inventory was conducted on September 24,2020 by HELIX Biologist and ISA Certified Arborist Stephanie McLaughlin, M.S. (WE-12922A). Woody plants in the proiect area with a trunk diameter of at least 4-inches at 4.5-ft above grade {diameter at breast height)were located and assessed, A diameter tape or calipers were used to verify each trunk diameter. The measurement from the trunk to the end of the longest lateral limb was estimated and used as the dripline radius' All accessible trees were numbered with a pre-printed aluminum tag. Approximate trunk locations were mapped using a sub-meter accurate global positioning system (GPS). Approximate tree locations are identified in Figure 3 of the arborist report {Appendix C).

The condition of each tree was rated one a scale of 1to 5, with 1 indicating poor condition, 3 indicating fair condition, and 5 indicating good condition. The rating considers factors health and structural factors such as the size, color, and density of the foliage; the amount of deadwood within the canopy; bud viability; evidence of wound closure; and the presence or evidence of stress, disease, nutrient deficienry, and/or insect infestation; trunk and branch configurationi canopy balance; the presence of included bark and other structural defects such as decay; and the potential for structural failure. 29

State and Federal Endanqered Species Acts
Special status species are protected by state and federal laws. The California Endangered Species Act (CESA; California Fish and Game Code Sections 2050 to 2097) proteEts species listed as threatened and endangered under CESA from harm or harassment. This law is similar to the Federal Endangered Species Act of 1973 (FESA; 15 USC 1531 et seq.) which protects federally threatened or endangered species (50 CFR 1.7.11, and L7.L2; listed species) frorn take. For both laws, take of the protected species may be allowed through consultation with and issuance of a permit by the agency with jurisdiction over the protected species.

Califurnio Code of Regulations ond Californio Fish and Game Code The official listing of endangered and threatened animals and plants is contained in the California Code of Regulations Title 14 5 670,5. A slate candidate species is one that the California Fish and Game Code has formally noticed as being under review by CDFW for inclusion on the state list pursuant to Sections 2A74.2 and 2075.5 of the California Fish and Game Code. CDFW also designates Species of Special Concern that are not currently listed or candidate species.

Legal protection is also provided for wildlife species in California that are identified as "fully protected animals." These species are protected under Sections 3511 (birds), 4700 (mammals), 5050 {reptiles and amphibians), and 5515 (fishes) of the California Fish and Game Code. These statutes prohibit take or possession of fully protected species at any time. The CDFW is unable to authorize incidentaltake of fully protected species when activities are proposed in areas inhabited by these species. The CDFW has informed non-federal agencies and private parties that they must avoid take of any fully protected species. However, Senate Bill (SB) 618 {2011} allows the CDFW to issue permits authorizing the incidental take of fully protected species under the CESA, so long as any such take authorization is issued in conjunction with the approval of a Natural Community Conservation Plan that covers the fully protected species (California Fish and Game Code Section 2835)' Calilornia Native Plant Prctedion Act
The California Native Plant Protection Act of 1977 (Californla Fish and Game Code Sections 1900 to 19L3) requires all state agencies to use their authority to implement programs to conserve endangered and otherwise rare species of native plants. Provisions of the act prohibit the taking of listed plants from the wild and require notification of CDFW at least 10 days in advance ofany change in land use other than changing from one agricultural use to another, which allows CDFW to salvage listed plants that would otherwise be destroYed.

Nesting and Migrutory Birds
Nesting birds are protected by state and federal laws. California Fish and Game Code (93503, 3503,5, and 3800| prohibits the possession, incidental take, or needless destruction of any bird nests or eggs; Fish and Game Code $3511 designates certain bird species "fully protected" (including all raptors), making it unlawful to take, possess, or destroy these species except under issuance of a specific permit.

The Attorney General of California has released an opinion that the Fish and Game Code prohibits incidental take. Under the Migratory Bird Treaty Act (MBTA) of 1918 (16 USF $703-711.), rnigratory bird 30

species and their nests and eggs that are on the federal list (50 CFR $10.13) are protected from injury or dlath, and project-related disturbance must be reduced or eliminated during the nesting cycle' The U,5. court of Appeals for the 9th circuit {with jurisdiction over california) has ruled that the MBTA does not prohibit incidental take (952 F 2d 297 - Court of Appeals, 9th circuit, 1991), City of Folsom Tree Preservotion Ordinance
Requirements related to biological resources also include protection of existing trees and specifies measures necessary to protect both ornamental and native oak trees. Chapter 12.16 ofthe Folsom Municipal Code, the Tree Preservation Ordinance, further regulates the cutting or modification of trees, including oaks and specified other trees; requires a Tree Permit prior to cutting or modification; and establishes mitigation requirements for cut or damaged trees (city of Folsom 2020b)' The Tree preservation ordinance

lurisdictional Woterc
Any person, firm, or agency planning to alter or work in "waters of the U.S.," including the discharge of dredged or fill material, must first obtain authorization from the U.S. Army Corps of Engineers (UsAcE) undei Section 404 of the Clean Water Act (cwA). Section 401 requires an applicant for a federal license or permit that allows activities resulting in a discharge to waters of the U'S' must obtain a state certification that the discharge complies with other provisions of the CWA. The Regional Water Quality Control Board (RWeCB) administers the certification program in California. The RWQCB also regulates discharges of pollutants or dredged or fill material to waters of the State which is a broader definition than waters of the U.S.

The CDFW requires notification prior to commencement of any such activities, and a Lake and Streambed Alteration Agreement (LSAA) pursuant to Fish and Game Code Sections 1601-1503, if the activity may substantially adversely affect an existing fish and wildlife resource.

Hobltqt Types/ Vegetolion Communilles
Habitat types/vegetation communities in the project site include blue,oak woodland and ephemeral and intermittent drainages.

Blue Ook Woodlond
Blue oak woodland is the predominant habitat type in the project site and occupies approximately 4,82- acres within the site. Vegetation in the blue oak woodland habitat consists primarily of blue oak (Quercus douglosii) and interior live oak lQuercus wislizenil, with some non-native species including mulberry lMorus o/bo), Chinese tallow (Triodico sebiferal, Chinese hackberry {Celtis sinensis}, and ornamental cherry (Prunus sp.). The understory is dominated by non-native grasses and forbs, including cultivated oats {Aveno sp.), ltalian rye grass (Festuca perennisl, and yellow star-thistle (Centoureo solstitiolisl. Disturbed areas, such as bike trails and jumps occur beneath the canopy of the oak woodland, and there is a significant amount of trash and debris in these areas. A small segment of the bike trail occurs in this habitat.

Topogrophy
The terrain in the proiect site and vicinity is locally flat. The elevation on the project site ranges from 350- to 370-ft above mean sea level and has low to moderate sloping from east to west. $olls
The project site includes two soil mapping units (NRCS 2O20): Argonaut-Auburn-Urban land complex, 3 to 8 percent slopes and Argonaut-Auburn complex, 3 to 8 percent slopes. Soils on the Nationat Hydric Soils List for Sacramento County (NRCS 2015) are not present in the project site.

Both soils occur on hills and are derived from residuum weathered from metamorphic rock. A typical profile of the Argonaut-Auburn-Urban land complex and Argonaut-Auburn complex, 3 to 8 percent slopes include loam from 0- to 1.4-inches, clay from 14- to 29-inches and bedrock from 29- to 33-inches; the depth to water table is more than 8O-inches.

Speciol-Sfolus Plont Species
No special-status plant species were determined to have the potentialto occur on the project site or be impacted by the proposed project. Of the 17 regionally occurring special-status plant species that were identified during the database queries and desktop review, the majority occur in wetland habitats such as vernal pools or seeps, which are absent from the site. Several others are limited to grassland or 32

cismontane woodland habitats. Although the site contains blue oak woodland, the study area is located in an urban area dominated by non-native species that does not provide suitable habitat for special status plant species. Therefore, no impacts to special-status plants are anticipated as a result of the proposed project,
Specicl-Slotus Wlldlile SPecles
A total of 23 regionally occurring special-status wildlife species were identified during the database searches and desktop review. The majority of the special-status wildlife species are associated with aquatic habitats of the adjacent Sacramento Valley such as rivers, sloughs, and freshwater wetlands, including vernal pools. The remaining species are associated with specific habitats such as bats roosting in rocky habitats, caves or abandoning buildings, which are not present in or near the study area' There are no reported occurrences of special-status animal species on or adjacent to the site' However, the site provides suitable habitat for white-tailed kite {Elanus leucurusl and other nesting migratory birds. These species are discussed briefly below. Species determined to have no potentialto occur on the project site or be irnpacted by the proposed project (Appendix D) are not discussed further in this report.

White-Tailed Kite
White-tailed kite is a year-round resident in coastal and valley lowlands, where it inhabits herbaceous and open stages of most habitat types. lndividuals forage in grasslands, farmlands, and wetlands, preying mostiy on small diurnal mammals. Nests are built near the top of dense tree stands, usually near open foraging areas (Zeiner et al. 1988).

No white-tailed kites were observed during any of the biological surveys conducted for the proposed project. The nearest reported extant occurrence of white-tailed kite in the CNDDB is located approximately 3-miles southwest of the project site near Lake Natoma (CDFW 2020). Nesting habitat is present on the site in large trees and foraging habitat is present in the ruderal vegetation' However, irabitat for white-tailed kite is marginal due to the urban character of the surrounding area' No adverse effects to white-tailed kite foraging habitat are anticipated as a result of the loss of oak woodland habitatthatwould occurdueto developmentof the proposed project. Non-breedingadults could readily avoid contact with construction equipment or personnel by moving out of the construction area. Displacement of non-breeding adults would not be a significant impact. The project has potential for adverse effects to white-tailed kite through nest disturbance leading to destruction of eggs or nestlings if this species were to nest in or adjacent to the project site' Eggs and young still dependent on the nest would be susceptible to injury or mortality through physical contact or through nest abandonment caused by displacement of adults. Destruction of eggs or young would be a violation of the Fish and Game Code and a significant impact'
lmplementation of Mitigation Measure BIO-Ol would reduce impacts to white-tailed kite and other nesting birds to a less than significant level'

The project site provides suitable habitat for nesting migratory birds and raptors. However, migratory and non-game birds are protected during the nesting season by California Fish and Game Code. The project site and immediate vicinity provides nesting and foraging habitat for a variety of native birds common to urbanized areas. Nests were not observed during surveys; however, a variety of migratory birds have the potential to nest in and adjacent to the site, in trees, shrubs and on the ground in vegetation.

Project activities such as clearing and grubbing during the avian breeding season {February 1 - August 3L) could result in injury or mortality of eggs and chicks directly through destruction or indirectly through forced nest abandonment due to noise and other disturbance. Needless destruction of nests, eggs, and chicks would be a violation of the Fish and Game Code and a significant impact.

Aquolic Resource Evoluolion
The project site is located in the City of Folsom in the Upper American River hydrologic unit (HUCL2:
130201110201). NWI mapping shows no aquatic features on the project site' HELIX conducted a routine assessment of waters of the U.S. and State on September 30,202O, generally in accordance with the U.S. Army Corps of Engineers' (USACE) Corps of Engineers Wetlands Delineation Manual and the Regionalsupplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0). A formal delineation of wetlands was not completed. HELIX identified two aquatic resources; an intermittent drainage and an ephemeral drainage totaling 0.04'acre of aquatic resources that are potentially jurisdictional waters of the U,S. and state. The drainage features are depicted on the Habitat and Resource Map, which is included in Attachment A of Appendix D. No other aquatic resources are present on the site.

The intermittent drainage totals 0.03-acre and flows in a southwesterly direction along the northern boundary of the project site. The intermittent drainage is fed by an unnamed emergent wetland swale located north of the site on the Folsom State Prison grounds, via a 24-inch metal culvert that runs beneath Natoma Street to enter the project site. The drainage also receives stormwater runoff from Natoma Street. The water to the site flows intermittently, with water persisting after rain events. The banks of the drainage are incised with a stream channel that is approximately 3-ft wide at the ordinary high-water mark. The intermittent drainage on the project site does not support wetland vegetation, with most of the vegetation within the feature consistent with vegetation in the blue oak woodland vegetation community. Upon leaving the site, the intermittent drainage continues in a southwesterly direction and enters an unnamed tributary to the American Riverllake Natoma west of the prison.

An ephemeral drainage is characterized as a feature with a bed and a bank that channels water from uplands and typically only flows during periods of precipitation. Ephemeral drainages typically do not support wetlands due to their brief hydroperiods, although they typically have an incised bank. ln the project site, there is one ephemeral drainage totaling 0.01-acre that crosses the eastern portion of the site and intersects with the intermittent drainage. The ephemeral drainage in the project site supports vegetation consistent with understory vegetation described in the blue oak woodland and is dominated by weedy grasses and forbs.

Determination of regulatory jurisdiction must be made by the U'S' Army Corps of Engineers (USACE), central valley Regional water Quality control Board (cvRWQcB), and cDFw. lt is likely that impacts to the drainages would occur as a result of the proposed proiect, which would be a significant impact if they are considered waters of the U.S. or state or subject to CDFW iurisdiction' Protecled Trees
A total of 111 trees are present on the site, including 94 blue oaks, seven Fremont's cottonwoods lpopulus fremontiil,four interior live oaks, two Gooding's black willow (Solix gooddingiil , one mulberry, one Chinese hackberry, one Chinese tallow, and one ornamental cherry (Figure 3)' The City of Folsom regulates trees under Section 12,16 of the Folsom Municipal Code {Tree Preservation Ordinance}' A peimit is reguired to remove native oaks {defined as valley oak, blue oak, interior live oak, and coast live oak) rneasuring 6-inches in diameter at standard height (i.e., 54-inches above natural grade, DSH), or a multi-stemmed native oak measuring a total of 2o-inches at DSH. For a tree with a common root system that branches at the ground, DSH is defined as the sum ofthe diameter ofthe largest trunk and one-half the cumulative diameter of the remaining trunks measured at 4.5-ft above natural grade.

A total of 77 trees on the project site are considered protected by Folsom City Code. None of the Fremont,s cottonwood, Chinese hackberry, Chinese tallow, mulberry, ornamental cherry or Gooding's black willow are protected. See Attachment B in Appendix C for additional data on the trees found on the project site.

Table I outlines the number of trees, with their respective DSH, to be impacted or to be retained' The project includes a total of 111 trees on the project site, of which 77 ttees are protected by the Folsom Litv coa". of the total 77 protected trees, 55 protected trees require mitigation (the remaining 12 trees do not warrant mitigation due to poor health). Underthe proposed proiect,30 protected trees, with 473.l-inches at DsH, would be retained. The proposed project would result in direct or indirect impact of the remaining 47 protected trees, which would require 571.3-inches at DSH of mitigation' However, the final mitigation for the impact of protected trees is to be determined by the City Arborist prior to issuance of a City Grading Permit.

a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? Less than significant with mitigation. The trees and understory grassland areas within the project site provide suitable nesting habitat for white-tailed kite and other raptors as well as other native birds and large trees adjacent to the site provide nesting habitat for raptors. Removal of vegetation containing active nests would potentially result in destruction of eggs andlor chicks; noise, dust, and other anthropogenic stressors in the vicinity of an active nest could lead to forced nest abandonment and mortality of eggs and/or chicks. Needless destruction of eggs or chicks would be a violation of the Fish and Game Code and a significant impact. Pre-construction surveys should be conducted prior to project implementation to determine if nesting birds are present on or adjacent to the site, so that measures could be implemented if needed to avoid harming nesting birds. lmplementation of Mitigation Measure BIO-01would reduce impacts to white-tailed kite and other nesting birds to a less than significant level.

Mititation Measure BIO{I1: Avoid and minimize impacts to white-tailed kite and other nesting birds. o lf project {construction) ground-disturbing or vegetation clearing and grubbing activities commence during the avian breeding season (February 1- August 31), a qualified biologist shall conduct a pre-construction nesting bird survey no more than 14 days prior to initiation of project adivities and again immediately prior to construction. The survey area shall include suitable raptor nesting habitat within 500-ft of the project boundary (inaccessible areas outside of the project site can be surveyed from the site or from public roads using binoculars or spotting scopes). Pre-construction surveys are not required in areas where project activities have been continuous since priorto February 1, as determined by a qualified biologist. Areas that have been inactive for more than L4 days during the avian breeding season must be resurveyed prior to resumption of project activities. lf no active nests are identified, no further mitigation is required. lf active nests are identified, the following measure is required; o A suitable buffer (e.g., 500-ft for raptors; 100-ft for passerines) shall be established by a qualified biologist around active nests and no construction activities within the buffer shall be allowed until a qualified biologist has determined that the nest is no longer active (i.e., the nestlings have fledged and are no longer reliant on the nest, or the nest has failed). Encroachment into the buffer may occur at the discretion of a qualified biologist. Any encroachment into the buffer shall be monitored by a qualified biologist to determine whether nesting birds are being impacted.

With implementation of Mitigation Measure BIO-01, impacts to the white-tailed kite and nesting birds would be less than significant.
b) Have a substantial adverse effect on any riparian habitat or other sensitlve natural community identified in local or regional plans, policies or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service?
No impact. No riparlan habitats, sensitive natural communities, or other protected habitats are located on or adjacent to the project site. Therefore, no impact would occur. 36

c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
Less than significant with mitigation. The 0.04-acre of aquatic features located on the project site are potentially regulated by the USACE, CVRWQCB, and CDFW under the Clean Water Act, Porter-Cologne Act, and Section 1500 of the Fish and Game Code. Therefore, removal or fill of the aquatic features would likely require a permit from these agencies. ln order to avoid impacts to jurisdictional wetland and waters, Mitigation Measure BIO-02 would be implemented, mitigating impacts to a less than significant level.

Mitigation Measure BIO-02: Avoid and minimize impacts to jurisdictional wetland and waters Prior to start of construction, the project proponent shall either prepare a formal delineation and submit it to the USACE for verification or obtain verification based on the mapping of aquatic resources in this report as well as contact the USACE, CVRWQCB, and CDFW to determine the need for permits and secure any required aquatic resources permits for impacts to waters of the U.S./State from the USACE, CVRWQCB, and CDFW, pursuant to Sections 404 and 401 of the Clean Water Act, the California Water Code, Section 1600 of the Fish and Game Code, and the State Water Resource Control Board Dredge and Fill Policy. The project proponent shall comply with all conditions of such permits including providing compensatory mitigation at a minimum L:1 ratio as required to achieve no net loss of wetlands or other waters. d) lnterfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
No impact. The project site is surrounded by development including Prison Road and Folsom State Prison to the north, Cimmaron Circle and single-family homes to the east, PG&E powerlines, single family homes, and duplexes to the south, and Fargo Way, Office Space, and Folsom City Police Department to the west. The project site does not provide any wildlife movement corridors or wildlife nursery sites. Therefore, there would be no impacts to wildlife corridors or the use of native wildlife nursery sites as a result of the proposed project.
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?
[ess than significant impact with mitigation. Of the 111trees on the project site, 77 trees are considered protected by Folsom City Code. lf protected trees will be removed by the proposed project mitigation will be required per Section I2.1'6.L50'
Protected trees rated 3,4 or 5 shall be replaced at a ratio of one-inch equivalent for every one-inch of DSH removed as shown in Table 8. Protected trees rated 2 shall be replaced at a ratio of one-half-inch equivalent for every one inch removed. Protected trees rated 0 or 1 require no replacement or any other mitigation. Mitigation for trees can be done through on-site replacement planting payment of in lieu fees, or a combination thereof.

Of the 77 trees protected by Folsom City Code, only 65 trees require potential mitigation based on having a health rating of 5,4,3, or 2. Of those 65 trees potentially requiring mitigation, the proposed project would only result ln direct or indirect impact to 47 protected oak trees, which would require 571,3-inches at DSH of mitigation (Table 7).

The discussion below is based on a cultural resources assessment prepared by HELIX Environmental Planning, lnc. (HEUX 2}22bl, attached to this lnitial Study as Appendix E. This assessment, which addresses both archaeological and architectural resources, is based on the results of an archival records search, Native American coordination, and a pedestrian survey of the project site.

Envlronmentol Setllng
State and federal legislation require the protection of historical and cultural resources. ln 797t, President's Executive Order No. 1L593 required that all federal agencies initiate procedures to preserve and maintain cultural resources by nomination and inclusion on the National Register of Historic Places. ln 1980, the Governo/s Executive Order No. 8-64-80 required that state agencies inventory all "significant historic and cultural sites, structures, and objects under their jurisdiction which are over 50 years of age and which may qualify for listing on the National Register of Historic Places." Section 15064.s{bx1) of the CEQA Guidelines specifies that projects that cause "...physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historic resource would be materially impaired" shall be found to have a significant impact on the environment. For the purposes of CEQA, an historical resource is a resource listed in, or determined eligible for listing in the California Register of Historical Resources. When a project could impact a resource, it must be determined whether the resource is an historical resource, which is defined as a resource that:
(A) is historically or archaeologically significant, or is significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political or cultural annals of California; and,
(B) Meets any of the following criteria: 1) ls associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage; 2) is associated with the lives of persons important in our past; 3) embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or 4) has yielded, or may be likely to yield, information important in prehistory or history. The City of Folsom Standard Construction Specifications were developed and approved by the City of Folsom in May 2004 and updated in 40

April 2015. They include Article L1 - Cultural Resources, which provides direction on actions to be taken in the event that materials are discovered that may ultimately be identified as a historical or archaeological resource, or human remains (City of Folsom 2015).

Cultural Background
The following is a brief overview of the prehistory, ethnography, and historic background of the project area intended to provide a historical context for cultural resources that might be found in the vicinity of the APE. This section is not intended to be a comprehensive review of the current resources available; rather, it serves as a general overview of human occupations and uses of the general project vicinity.

Prehistoric Background
Early archaeological investigations in central California were conducted at sites located in the Sacramento-San Joaquin Delta region. The first published account documents investigations in the Lodi and Stockton area (schenck and Dawson 1929). The initial archaeological reports typically contained descriptive narratives, with more systematic approaches sponsored by Sacramento Junior College in the 1930s. At the same time, University of California at Berkeley excavated severalsites in the lower Sacramento Valley and Delta region, which resulted in recognizing archaeotogical site patterns based on variations of inter-site assemblages. Research during the 1930s identified temporal periods in central California prehistory and provided an initial chronologicalsequence (Lillard and Purves 1936; Lillard et al. 1939). ln 1939, Lillard noted that each cultural period led directly to the next and that influences spread from the Delta region to other regions in central California (Lillard et al. 1939), ln the late 1940s and early 1950s, Beardsley documented similarities in artifacts among sites in the San Francisco Bay region and the Delta and refined his findings into a cultural modelthat ultimately became known as the CentralCalifornia Taxonomic System tCCfS). This system proposed a uniform, linear sequence of cultural succession {Beardsley 1948 and 1954). The CCTS system was challenged by Gerow, whose work looked at radiocarbon dating to show that Early and Middle Horizon sites were not subsequent developments but, at least partially, contemporaneous (Gerow L954, L974; Gerow and Force 1958), To address some of the flaws in the CCTS system, Fredrickson (1973) introduced a revision that incorporated a system of spatial and cultural integrative units. Fredrickson separated cultural, temporal, and spatial units from each other and assigned them to six chronological periods: Paleo-lndian (10000 to 6000 B.C.); Lower, Middle and Upper Archaic (6000 B.C. to A.D. 500), and Emergent (Upper and Lower, A.D. 500 to 1800). The suggested temporal ranges are like earlier horizons, which are broad cultural units that can be arranged in a temporal sequence {Moratto 1984). ln addition, Fredrickson defined several patterns-a generalway of life shared within a specific geographical region. These patterns include:
. Windmiller Pattern or Early Horizon (3000 to 1000 B.C.); r Berkeley Pattern or Middle Horizon (1000 B.C. to A.D. 500); and, . Augustine Pattern or Late Horizon {A.D. 500 to historic period}.

Brief descriptions of these temporal ranges and their unique characteristics are presented below. 4t

Windmiller Pattern or Early Horizon FOAO tu nOA B.C.)
The Windmiller Pattern, or, the Early Horizon culture, was centered in the Cosumnes district of the Delta and emphasized hunting rather than gathering, as evidenced by the abundance of projectile points in relation to plant processing tools. Additionally, atlatl, dart, and spear technologies used typically included stemmed projectile points of slate and chert. Obsidian projectile points, however, are sparingly found on Windmiller sites. The large variety of projectile point types and faunal remains suggests exploitation of numerous types of terrestrial and aquatic species {Bennyhoff 1950; Ragir 1972}. Burials occurred in cemeteries and intra-village graves. These burials typically were ventrally extended, although some dorsal extensions are known with a westerly orientation and a high number of grave goods. Trade networks focused on acquisition of ornamental and ceremonial objects in finished form rather than as raw material. The presence of artifacts made of exotic materials such as quartz, obsidian, and shell indicate an extensive trade network that may represent the arrival of Utian populations into central California. Also indicative of this period are rectangular Holiotis and Olivella shell beads, and charmstones that usually were perforated,
Berkeley Pottern or Middle Horizon (1000 B.C' to A.D' 5AO) The Middle Horizon is characterized by the Berkeley Pattern, which displays considerable changes from the Early Horizon. This period exhibited a strong milling technology represented by minimally shaped cobble mortars and pestles, although metates and manos were still used. Dart and atlatl technologies during this period were characterized by non-stemmed projectile points made primarily of obsidian' Fredrickon (1973)suggests that the Berkeley Pattern marked the eastward expansion of Mi-Wuk groups from the San Francisco Bay Area. Compared with the Early Horizon there is a higher proportion of grinding implements at this time, implying an emphasis on plant resources rather than on hunting.

Typicat burials occurred within the village with flexed positions, variable cardinalorientation, and some cremations. As noted by Lillard, the practice of spreading ground ochre over the burial was common at this time (Lillard et al. 1939). Grave goods during this period are generally sparse and typically include only utilitarian items and a few ornamental objects. However, objects such as charmstones, quartz crystals, and bone whistles occasionally were present, which suggest the religious or ceremonial significance of the individual (Hughes 1994). During this period, larger populations are suggested by the number and depth of sites compared with the Windmiller Pattern. According to Fredrickson (19731, the Berkeley Pattern reflects gradual expansion or assimilation of different populations rather than sudden population replacement and a gradual shift in economic emphasis.

Augustine Pottern or Lote Harizon (A.D.500 to Historic Period) The Late Horizon is characterized by the Augustine Pattern, which represents a shift in the general subsistence pattern. Changes include the introduction of bow and arrow technology; most importantly, acorns became the predominant food resource, Trade systems expanded to include raw resources as well as finished products, There are more baked clay artifacts and extensive use of Haliotis ornaments of many elaborate shapes and forms. Burial patterns retained the use of flexed burials with variable orientation, but there was a reduction in the use of ochre and widespread evidence of cremation (Moratto 1984). Judging from the number and types of grave goods associated with the two types of burials, cremation seems to have been reserved for individuals of higher status, whereas other individuals were buried in flexed positions, Johnson {1976) suggests that the Augustine Pattern represents expansion of the Wintuan population from the north, which resulted in combining new traits with those established during the Berkeley Pattern.

Central California research has expanded from an emphasis on defining chronological and cultural units to a more comprehensive look at settlement and subsistence systems. This shift is illustrated by the early use of burials to identify mortuary assemblages and more recent research using osteological data to determine the health of prehistoric populations (Dickel et al. 1984). Although debate continues over a single model or sequence for central California, the general framework consisting of three temporalcultural units is generally accepted. Having said that, the identification of regional and local variation remains a major goal of current archaeological research.

Ethnographic Background
The cultural groups that occupied the project area at the time of Euro-American contact around 1845 are the Southern Maidu, sometimes called the Nisenan. This group speaks a language related to the Penutian stock, and it is generally agreed that they entered the region sometime after 1750 AD, and that their territory included the Bear River, American River, Yuba River, and southern portions of the Feather River drainages (Wilson and Towne 1978:387). Southern Maidu settlements were often located on ridges that separated parallel streams, or terraces located part way up slopes (Kroeber 1925).

The Southern Maidu village of Yodok was thought to have been originally located on the south side of the American River, in the approximate vicinity of the current town of Folsom (Kroeber 1925:394). Later ethnographers however, depict the village on the north side of the river {Bennyhoff t977:L25, L65; Wilson and Towne 1978:3881, close to the present-day location of the Cliff House Restaurant (located at 9900 Greenback Lane). lt is suspected that additional large settlements existed in the region prior to Euromerican contact which went undocumented due to the speed with which the Southern Maidu way of life was impacted by white settler colonialism.

Ethnographic descriptions ofthe Southern Maidu suggest a varied subsistence strategy based on the exploitation of available resources. They hunted a variety of large and small mammals, (including deer, bear, elk, antelope, and rabbit), fish (salmon, trout, and eel), and birds {waterfowl, crows, and pigeons), and gathered numerous edible seeds, nuts, berries, herbs, and native fruits (Kroeber 1925). The Maidu were nomadic throughout the year, following game and gathering plants. Population movements were predicated upon the changes of seasons in an effort to make subsistence gathering easier. Winter vilfages were formed along drainages at elevations below 2,500-ft (Johnson L982:74-751. Spring, summer, and early fall were spent at higher elevation camps, where resources were gathered, prepared, and stored for winter (Wilson and Towne 1978:388).

Maidu dwellings include a conical structure built out of poles thatched with bark, sticks, leaves, and pine needles. These structures were often built on top of shallowly excavated pits, with dirt built up around their perimeters. These structures measured between 10- and 15-ft in diameter. Larger Maidu villages often included dance houses, which measured between 20- and 40-ft in diameter, as well as other larger structures which functioned as sweat houses and lodges. These larger structures extended down into the subsurface, with 10- to 20-ft high posts used to support a domed roof which consisted of poles and thatched sticks, bark, and pine needles. An outer layer of earth, measuring roughly l-foot thick, was used to sealthe structure against the elements (Kroeber 1925:407-408)' The epidemic of 1833, which was brought by Euromericans into the Folsom area, had terrible ;mpacts on local Maidu populations. Thought to be malaria, this epidemic is estimated to have killed up to 75 percent of the Sacramento Valley native population, Maidu included. Another major impact to the Maidu way of life came with the discovery of gold in Coloma in 1848. This prompted thousands of 43

miners to move into the region and stake claims for mining operations. This carving up of territory gn maps was quickly followed by the removal of trees, and the diversion of rivers and creeks from their natural beds, resulting in the siltation of local streams. Beyond the environmental degradations these activities caused, mining operations radically reduced the hunting and gathering territories of the Maidu and other native American groups all but extinguishing their means of maintaining self-sufficient levels of food collection/production as well as their capacity to collect materials used in the crafting of tools, structures, trade goods, and medical supplies (Levy 1978, Wilson and Towne 1978). By the 1870s, the surviving Maidu were largely working in Euro-American owned mines and ranches or working as day laborers in industrialor agricultural settings (Powers 1975). Still, Maidu people continue to live in the region to this day, and are striving to maintain, reinvigorate, and safeguard their cultural heritage and traditional practices.

Historic Background
The first Europeans to visit the interior of California were Spanish expeditions launched to recapture Native Americans who had escaped from the rule of coastal missions {Heizer and Almquist 1971, McGruder 1950, Napton 1997:5). Catholic missions were the hallmark of the Spanish Period (L796-L8221 in California, during which time 21 missions were established by the Franciscan Order along the coast between 5an Diego {among the earliest of missions} and San Francisco. Among the first Europeans to formally explore the CentralValley was Lieutenant Gabriel Moraga, who led excursions in the area between 1806 and L808 to examine the area's main water ways including what we today call the American, Calaveras, Cosumnes, Feather, Merced, Mokelumne, Sacramento, San Joaquin, and Stanislaus rivers. ln 1813, Moraga again ventured into the Central Valley, this time focusing on the south, and coined the name of the San Joaquin River (Hoover et al. 2002:369). Luis Arguello led the last of the Spanish expeditions into the CentralValley in 1817 when he traveled up the Sacramento River, past current day Sacrarnenlo, and into the mouth of the Feather River before turning back to the coast (Beck and Haase t974:18,20, Grunsky 1989:3-4)'
The Mexican Revolution, which took place between 1810 and 1821, resulted in the end of Spanish rule in modern day California and ushered in Mexican governance in the area, which was marked by an extensive issuance of land grants, mostly of lands in the interior of the state. Californios (or Mexican Citizens in California who were given land grants) were given locations by the Mexican Republic in the interior, with the goal of increasing populations in areas further from the coast where Spanish era settlements had already been established and developed into bustling areas of commerce.

Settlement of the Sacramento area began by late 1830s and early 1840s, when entrepreneurs such as John Sutter and lared Sheldon obtained land grants from the Mexican government in exchange for an agreement to protect Mexican interest in these remote regions. ln 1839, John Sutter built the earliest Euro-American settlement within Sacramento County. Named Sutter's Fort, it was well known outpost that brought with it an increase in Euro-American trappers, hunters, and settlers to the Sacramento area. John Sutter also founded New Helvetia, a trading and agricultural outfit, that was based out of Sutter's Fort, close to the location where the Sacramento and American rivers split, near today's City of Sacramento (Hoover et al. 2002).

The Mexican period was also characterized by exploration of the western Sierra Nevada mountain range by American fur trappers and later, miners. Jedediah Smith, an American trapper, is known to have explored the Sierra Nevadas in 1826 and 1827, entering the Sacramento Valley and traveling along the American and Cosumnes rivers and through the San Joaquin Valley. Soon after other trappers ventured 44
