II. FINANCIAF, IMPACT. The estimated project cost is $5.5 million funded by Utility Tariff fands (36®/x), diverted Rodeo Crockett Transportation Improvement funds(36%), and Redevelopment Agency funds (28%). III. REASONS FOR RECOMMENDATION/BACKGROUND: The Parker Avenue Reconstruction and Undergrounding Project is one of several downtown infrastructure improvements identified in the Rodeo Downtown/Waterfront Specific Pan. The project is needed in order to enhance the appearance and economic viability of the existingcomniercial strip. With the improvements, th e speed of through traffic will be reduced;thereby creating a more pedestrian fi~endly enviroriment that is consistent with the goals of the Specific-Plan. The project is expected to assist in the revitalization of the downtown core area and the re-establishment of Rodeos as a viable commercial and recreational center. The project consists of reducing the number of traveled way lanes to one in each direction with shoulders for parking, undergroundin.g the overhead utilities, incorporating a center median and left turr. lane and incorporating landscaping and other improvements. The protect has been determined to be in compliance with the General Plain, A. mitigated Negative Declaration of environrnental significance pertaining to this project was published on November 25,2002. The Board has considered the mitigated Negative Declaration and litigation Monitoring Program together with all comments received during the public review period. Ike CONSEQUENCES OF NEGATIVE ACTION: Delay in approving the project will result in a delay of design and construction and may jeopardize funding.

Public Resources Code and the "Guidelines for implementation of the California Environmental ental Qua€ity Act of 1970" as amended to date, this is to advise you that the Public Works Department of Contra Costa County has prepared an intim study on the ;following project: The purpose of the Parker Aven:�e project is to enhance the appearance and economic viability of the existing connenercial strip. The projects expected to assist in the revitalization of the downtown core area and the re- establishment of 145dec as a v€a'o le co nmercial and recreational center. The project Dili reduce the number of traveled way lanes to one in each direction with shoulders for parking, underground, the overread utilities, incorporate a center median and :eft turn lane, and incorporate landscaping.. Upgrades to Parker Avenue will include design components such as trenching and undergrounding of overhead utilities, reconstruction of pavement, construction of concrete curb, gutter, and sidewalk, construction of parking bulbs to better delineate parking, and construction of a center median island with textured paving with associated curb ramps, striping, and ;anyscap;nq addition, removal of ex;st,ng concrete paving, trees, and cion ge will also be required. The proposed proJect, will include drainage improverner is along 2"d Street, 4t5 Street and at the Parker Avenue/San Pablo Avenue bridge at rodeo Creel. The project will also include the installation cf a traffic signal at the intersection of barker Avenue and 7th Street to address an existing site distance concern and updating the signals at 2nd and 4th Streets to include new controllers and cabinets. in addition, a mid-block pedestrian-only traffic signal wi':.l be placed between 4" and Ott, Streets, in front of Lefty Gomez Ballpark. A Site Safety and Healt i f ar? certified by an industrial :hygienist will be prepared as part of the undergrounding and reconstruction of Parker Avenue to ensure proper handling, management and disposal of any contaminated soils and groundwater. Undergrounding activities for the project will consist of relocating overhead utility lines beiow the roadway surfaces Existing power poles will be removed and utility services will be reconnected to the new underground system, The utility undergrounding work within the County roadway which includes the main and lateral trenches will be built at no expense to the property owners. The underground .;tility district will also provide up to 100 feet of lateral trenching and conduits or, private property, if needed, to bring service up to the foot of the Wilding wall where the utility service box is located. The property owner will be responsible for the conversion of the electric service box to receive underground service and any lateral trenching and conduit on private property in excess of 100 feet. The cost of converting electric service boxes is dependent upon the building usage and condition of existing equipment. Historically, property owners have been responsible for the cost to convert their power panels in undergrounding prciects throughout the County. However, changes by the Public Utilities Commission (PLIC) in December 1999 will allow Rule 20 funds to contribute in part to the cost of, power panel conversions. This contribution will defray some of the cos; to the property owner lith the Rule 20 contributions, the typical cost for a residential property is approximately 1,50043,000. Commercial properties will cos; approxim, ately $3,000-$3,000. Page I of 2 Ail affected property owners as shown on the last equalized assessment roll and all utilities affected were given notice of the opportunity to attend a public hearing that was heli; on March 14, 2000, regarding the ;utility undergrouinding. At the hearing, all interested persons were provided with the opportunity to voice any concerns regarding the undergrounding. Subsequently, the Contra Costa County Board of Supervisors found that the undergrounding of utilities along Parker Avenue is in the interest of the pubrIc health, safety and welfare. All affected uti`ities and persons owning real property within the underground utility district were notified of the Board Acton and informed that they would be responsible for the costs associated with the conversion of their utility service box to receive underground service, and any lateral trenching and conduit in excess of 100 fee..

The proposed project will include drainage improverments along 2"d Street, 4"h Street and at the Parker Avenue/San Pablo Avenue bridge at Rodeo Creek. The speed of through traffic will be reduced by narrowing the roadway, thereby creating a more pedestrian friendly environment that is consistent with the goals of the Rodeo Downtown/Waterfront Specific Plan. The reduction in capacity is not considered significant based on current and predicted future traffic use. With implementation of the project, sufficient roadway width will be provided to accommodate emergency vehicles, transit, on- street parking, and related maneuvering area. During construction the roadway will be reduced from four ;ares to two lanes with only minor disruption to local traffic based on the current traffic level in the area. There will be at least one lane open in each direction during construction to minimize traffic; impacts. There are also nurmerous parade` streets in the downtown area that will continue to provide access to the downtown area in the evert that detours are necessary. A consultant was hired td determine where :hazardous materials contamination of soil and groundwater may be encountered during construction trenching activities. used upon the consultant's findings, excavated soils and groundwater will likely contain varying concentrations of petroleums hydrocarbons and may contain volatile organic compounds. Data suggest that the highest levels of hydrocarbons in soil and groundwater will likely be encountered it the intersection of Parker Avenue and 4tn Street. Due to the presence of petroleum hydrocarbons and/or certain volatile organic compounds, excavated soils will be tested to determine whether they can be reused as fill material or whether they are contaminated and must be properly disposed of at all,:: appropriately licensed Mass 11 or Mass lil disposal facility. In addition, groundwater encountered during construction will either be tested as encountered or contained in a portable aboveground tank and tested to determine whether it is appropriate to dispose of the water in the sanitary sewer, system. A Site Safety and Health Plan certified by an industrial hygienist will be prepared as part of the undergrounding and reconstruction of Parker Avenue to ensure proper handling, management and disposal of contaminated soils and groundwater. Real Property transactions will be required along the length of the project alignment including right of way acquisition and right of entry to construct standard Americans with Disabilities Act (ADA) curb ramps and associated improvements at the southwest corner of San Pablo Avenue and Railroad Avenue (APN 357-182-004), the area fronting the apartments at 601 Parker Avenue (APN 357-131-000), the south side of San Pablo Avenue/Parker Avenue lust west of 601 Parker Avenue (APN 357-139-306), the southeast corner of Parker Avenue and 1st Street (APN 357-179-090), the northwest, northeast and southwest corners of Parker Avenue and 2"d Street (APIs 357-042-009, 357-971-006, 357-051-003), the southwest corner of Parker Avenue and 3' Street (APN 357-031-001), the northwest and northeast co>rners o Parker Avenue and 4`' Street (APNs 357-03 -0332, 357-951-002), tihe . orthwest corner of Parker Avenue and 69" Street (APIA 357-101-003), and the northwest corner of Parker Avenue and 7th Street (357-111-0}10).

Reconstruction and Frontage I—provemenls Recons-ruction of Parker Avenue is *hie second step, in the revitalization of Parker Avenue and downtown Rodeo, Roadway work will begin upon comp'efion of the undergrounding activities. Parker Avenue wit!, be reconstructed to incorporate the streetscape enhancements identified in the Rodeo Specific Plan. Completion of the roadway reconstruction prclect M111 L. create a visually prominent,nent, tree lined boulevard uniting downtown Rodeo, the waterfront, and t e surrounding community. Beyond the aesthetic quality of new construction, the pavement along Parker Avenue is in need of reconstruction for several reasons. The :most i€nportant of these is the proposed lane reconfiguration of Parker Avenue as outlined in the Rodeo Specific Plan. Parker Avenue, ;n its current configuration, is two lanes in each direction with smoulders for parking plus a center two Way left turn lane between Stn, and 7t". The curb pavement width is nearly 25 meters (80 feet) wide. The proposed configuration will reduce the number of traveled way lanes to one in each direction, with bicycle lames and shoulders for parking. The two-way 'left turn lane would be replaced by a center island median with left turas allowed at intersections. Although most of Parker Avenue is in relatively good pavement condition, another reason full ::. construction s deemed necessary ;s to eliminate the no�oceaole centerline crown}. At one time, Parker Avenue consisted of concrete pavement and in fact, much of the old concrete slab is still burled beneath the existing roadway. It is suspected that this is the ;amain contributing factor to the height of the existing crown, Successive overlay projects in the past have exacerbated the problem. Complete reconstruction will eliminate this crown and restore the roadway Lo a standard two percent cross slope. The Parker Avenue Project will also include the installation of a traffic signal at the intersection of Parker Avenue and 7th Street to address an existing site distance concern and updating the signals at 2" and 4th Streets to include new controllers and cabinets. In addition, at the request of the community, a pedestrian-only traffic signal will be placed between 4t" and 8`" Streets, in front of Lefty Gomez Ballpark, As a con;ponent of the project, drainage improvements will occur along Parker Avenue and some of its cross streets including 2nd Street, Ott' Street and at the San Pablo/Parker Avenue bridge over Rodeo Creek. Along 2"a Street there is an existing culvert that outfalls into Rodeo geek. This outfall is at the appropriate elevation for larger replacement drainage pipes (increased from the existing 12" size to 18,:) to be tied directly into the existing pipe to handle stormwater;lows at this location. The size of the drain pipe is being increased to bring the drainage facilities up to County standard. At the 4tr Street location, in order to more effectively convey stormwater flows to Rodeo geek, the existing outfall will be replaced with Me larger pipe and the outfall will be lowered approximately 1.5 feet. Construction activities at this location will include excavating along 4t" Street to place the neva larger pipe; breaking through the existing grouted rock slope protection� and tying in the drain} pipe at the lower elevation°. used on the height of the outfall above the channel invert and the timing of the construction activities (during the dry season), dewatering will not be necessary at this location. The new culvert at the San Pablo/Parker Avenue bridge will function to drain storm flows to Rodeo geek from drainage inlets located along a newly installed sidewalk along Parker Avenue. The outfall into tine channel will be punched through the existing concrete channel wall roughly five feet above the bed of the channel. The channel invert sits at roughly three feet below sea level; therefore, in this area of the creek, water is continually present, particularly during high tide events, T herefore, in order to facilitate the work on the concrete channel, Rodeo geek may require dewatering. An important component of the 'I rproved visual image of the downtown area is consistency i^ appearance. Nearly the entire frontage length of Parker Avenue is comprised of curb, gutter and sidewalk, The majority of sidewalk is 10 meters ('s u feet) wide, typical for a .......................................... ...................................................................._............_.. ......... ......... ......... ......... ........ ........ ......... ......... ......... ................. __ ......... . ........ ......... ......... ......... ...... ......... ......... ........ ......... ........ ........ ......... ......... ......... ......... ........ ............................................................................................. corr-IrnerCial area. While the Specific Plan calls for fronting sidewalks of 1,5 meters f5 feet; wide, it was not deemed practical: to remove and replace -all of the existing 3.0 meter Ode sidewalk, Instead deficient sections will be replaced. 'Deficient' is defined as any portion of I - or discoloration, or any section offsd curb, gi_ltfer, or sidewa�fk that severe cracking ; :_ewalk constructed by local property owners that weld not be consistent with new, broom fln:sh concrete (e.g. aggregate or tile).

To expand on the Street Tree concept, two 'Landmark "gees' will be placed at select 'oca'�ons.

Aark' can be loosely defined Pabi Avenue, San Pablo Avenue, and Railroad Ave:Avenue, and as any class oftree ororninent enough, in size and shape to prcivxe a visual focal point. A large oak is typical of this kind of tree description. Ground cover and-owering shrubs wili be used to enhance the appearance of the center island medians. As part of the center island median, a meW(2 foot) Strip of colored concrete will be added adjacent to the curb 0.6 =Lion of, the median. Not oniy would this irnprove the aesthetics of the islands, but it would also assist the General Services Department with the maintenance of, t center trees and ground cover. 3.

Utility Under KgRj#� Underg-rournding of unsightly overhead utility lines and removal of existing utility poles along Parker Avenue -will improve the aesthetics of this irsportant corridor in Rodeo and benent the community as a whole. Cor plettGrt of utility undergrourdnng is the first step in the revitalization of Parker Avenue and downtown Rodeo. Can larch. 14, 2444, the C=ounty Board of Supervisors formed an underground utility district for the downtown area of Rodeo. The district lim=as include all parcels ornting Parker Avenue and San Pablo Avenue from Willow Avenue to just east of Railroad Avenue. ria derground ng aot.vn es for the project wi consist o:relocating overhead uti-"y lines below the roadway surface. Existing power poles will be removed and utility services wri:be reconnected to the new underground system. The majority of the ester ated $2.4 million needed to construct this undergrourndnng project will care from utility tariffs HESENegDe-,Rev;sed.doc ?age 2 of 35 September,2002 (PG&E Rule 20 and Pacific Bell Rule 32 funds). The Undergrounding project is being coordinated with PG&E(project nurnber 30160625),Pacific Bell and AT&T Broadband. The utility undergrounding work within the County roadway which includes the main and lateral trenches will be built at to expense to the properly owners. Tl,,,e underground utility district will also pro vide up to 100 feet of lateral trenching and conduits on private property, if needed,to bring service up to the foot of the building wall where the utility service box. —Lne property owner will be responsible for the conversion Wf alae el ectr c service box to receive underground service and any lateral trenching and conduit on, private property in excess of 100 feet. The cost of con=verting electric service boxes is dependent upon,the building usage and condition of existing equipment. Historically,property owners have been responsible for the cost to convert their power panels in undergrounding projects throughout the County. However, changes by the Public Utilities Commission (PLIC)in December 1999 will allow Rule 20 finds to contribute in part to the cost of power panel -conversions, Phis contribution will defray some of the cost to the property owner. With the Rule 20 contributions,the typical cost for a residential property is approximately$1,50043,000. Cor=ercial properties will cost approximately 53,000-$8,000. All affected property owners as show-,on the last equalized assessment roll and all utilities affected were given notice of the opportunity to attend a public bearing that was held on March 14,2000,regarding the utilityundergrounding. At the hearing, all interested persons were provided with the opportunity to voice any concerns regarding the undergrounding. Subsequently,the Contra Costa County Board of Supervisors found that the undergrounding of utilities along Parker Avenue.is in the interest of the public health,safety and welfare. All affected utilities and persons owning real property within the underground utility district were notified of the Board Action and informed that they would be responsible for the costs associated wit"the conversion of their utility service box to receive underground service, and any lateral trenching and conduit in excess of 100 feet. Reconstruction and Frontage Improvements deconstruction of Parker Avenue is the second step in the revitalization of Parker Avenue and downtown Rodeo. Roadway work will begin.upon completion..of the undergrounding activities. Parker Avenue will be reconstructed to incorporate the streetscape enhancements identified in the Rodeo Specific Flan•,. Completion of the roadway reconstruction project will create a visually prominent,tree-lined boulevard :uniting downtown Rodeo,the waterfront, and the surrounding corn munity. Beyond the aesthetic quality of new construction, the pavement along Parker Avenue is in need of reconstruction, for several reasons. The most important of these is the,proposed lame reconfiguration of Parker Avenue as outlined in the Rodeo Specific Plan. Farber Avenue,in its current configuration, is two lanes in each direction with shoulders for parking plus a center two-way left tura lane between 6" and.7�, The club pavernnent=width is nearly 25 meters (80 feet)wide. The proposed configuration will reduce the number of traveled way lanes to one in each direction, with bicycle lanes and shoulders for parking. The two-way left tarn lathe would be replaced by a center island median with left tins allowed at intersections. Alt Lough most of Parker Avenue is in relatively good pavement condition, full reconsts vection is deemed necessary is to eliminate the noticeable centerline crown:. At one time, Parker Avenue consisted of concrete pavement and, in fact, rnuch of the old concrete slab is still!buried beneath the existing roadway. It is suspected that this is the grain contributing factor to the height of the existing crown. Successive overlay projects in the past have exacerbated the problem. Complete reconstruction will e in-irate this crown and restore the roadway to a standard two percent cross slope. HFSENegDecRev;sed.coc Page 3 of 36 September,2002 The Parker Avenue Protect will also include the installation ofatraffic signal atth-int--rsect-,on ,-fPa:,-ker Avenue and 7th Street to address an existing site distance concern and updating the signals at 2`�and 4'-' Streets to include new controllers and cabinets. Im addition, at the recuest of the community, a—. -.id-bock n, eCest—ali-on'y traffic signal wil,l be placed between 4'and 0"r.Streets, in front of Leffty Gomez Ballpark, As a corm)--nent of the project, drainage improvements will occur along Parker Avenue and some of it cross streets inchading 2" Street,4-h Street and at the San Pablo/Parker Avenue bridge over Rodeo Creek. Along 2'Street there is an existing-culvert that outfalls into Rodeo Creek, This outfall is at the appropriate elevation for larger replacement drainage pipes (increased from the existing 12"size to 18")to be'tied directly into the existing pipe to handle sto--,-nwa+,er flows at this location. 71he size of the drain pipe is being increased to b-'rig the drainage facilities up to County standard. At the 4�, Street location, in order to more effectively convey start:water flows to Rodeo Creek, Lrie existing outfal' will be renaced with the larger pipe and the outfall will be lowered approximately 11.5 feet, Construction act?vit; cs at this location will -include excavating along 4" Street to place the new larger pipe, breaking through the existing grouted rock slope protection and ty--ing ir.the drain pipe at the lower elevation, Based on the height ofille outfall, above the channel invert and the timing of the construeftn activities (during the dry season.) dewatering will' not be necessary at this location. The new culvert at the San Pablo/Parker Avenue bridge wi',l function to drain storm flows to Rodeo Creek from drainage inlets located along a newly installed sidewalk along Parker Avenue, The outfall into the chary dl will be puncied thro�igh the existing concrete ciaa>rael wall roughly five feet above the bed ofthe channel, The channel invert sits at roughly three feet below sea level; therefore, in this area of the creek, water is continually present,particularly during high tide events. Therefore, in order to facilitate the work or the concrete channel, Rodeo Creek may require dewatering. An important component of the improved visual irnage o,.rthe downtown area is consistency ire appearance. Nearly the entire frontage length of"Parker Avenue is comprised of curb, gutter and sidewalk. The rnqjority of sidewalk is 3.0 meters (10 feet) wide,typical for a commercial area. W.bile the Sjecific Plan calls for fronting sidewalks of 1.5 meters (5 feet)wide, it was not deerned practical to remove' and replace all of the existing 3.0 meter wide sidewalk. Instead deficient sections will be replaced. 'Deficient* is defined as any portion of curb, gutter, or sidewalk that had severe cracking or discoloration, or any section of sidewalk constructed by local prope.-Ity owners that would not be consistent with new,broom finish concrete (e.g. aggregate finish or tile). I Landscaping will be a critical clornponent of the Parker Avenue revitalization. The main feature of the landscaping pian is the 'Street Tree' concept. The plan proposes trees placed along the curb line on both sides of Parker Avenue and in the-center median island. Street trees will be large,broad-canopied,round- headed deciduous trees such as Chinese Hackbeny(Celtis sinensis) or Raywood Ash (Fraxinu's Or sus "RayiAiood"), planted approximately 50 feet on center. To expand on the tt Tree concept,two Street Landmark Trees' will be placed at select locations. The first location-is the intersection of Parker Avenue and Pacific Avenue, and the second location is the three-way intersection of San Pablo Avenue, San Pablo Avenue, and Railroad Avenue. 'Landmark' can be loosely defied as any class of tree prominent enough in size and shape t visual + o provide a vis I focal point. Alarge oak typical of this kind of tree descrii-P,10-11. Ground cover and flowering shrlabs will be-used to erlance the appearance of the center island ri--ledixis. As part of the center 4island median, a 0.6 rneter(2 foot) strip of colored concrete wi-31 be added ad:acent to ,-he curb portion, of tl e med'an. Not only would this improve the aesthetics of the islands,but-.it would also assist the General Services Department with the maintenance of the center trees and ground cover.

The reconstruction of Parker Avenue will not expose people or property to geologic hazards. Parker Avenue is located within an Alquist-Priolo Earthou�—Oce Ewalt Zone (A-PEFZ). Such zones are delineated by the State along known active faults, The active faults ih the area range front a Maxi=nurns Credible Earthquake(MCE)' of Richter rna.gnbtude 6.5 to 8.3. As a consequence of being located in an area of large, active faults,the rroject site will inevitao.y be exposed to seisiriica,ly induced grour d-sha": g and associated aza.rds.

X SUMMARY: Less Than Significant, As a component of the project, drainage improvements will occur along Parker Avenue and sorne of its cross streets inciudi ng 4 Street and at the San Pablo/Parker Avenue bridge over rodeo geek. Along 4L� Street there is ars exist-Ing culvert that outfalls into Rodeo geek.. The culvert at this loci+ion will be replaced with a larger pipe and lowered approximately 1.5 feet. Based on the existing height of the outfall above the channel invert and the tinning of the construction activities (during the dry season), dewatering will not be necessary at tris location. T:-,.e new culvert at the San Pablo/Parker Avenue bridge will ou+fail into the channel through the existing concrete channel wail roughly five feet above the bed of the channel. The channel invert sits at roughly three feet below sea level; t`^en.-fore,i tElis ea of the creaky water is continually present, particularly da rig high tide events. herefore in order to facilitate the work on the concrete charnel, rodeo Creek may require dewatering. In order to ensure there are no impacts to water quality at either outfall location,the construction of the orutfalls will occur during the suminier months when Rodeo Creek flows are as low as possible. Netting and/or other bar ier—mapterials will be installed to contain debris and silt so they do not.enter the creek as a result of construction activities. Fuelling and servicing of equiprient will occur outside the creek zone and removal of constriction-generated waste will occur on a daily basis. Sta-idard constructions safe+y practices Will by incorporated into the project to reduce the possibility of a spill of gasoline,oil, or other pollutant that could have a significant irnpact on water quality. General construction and grading activities could temporarily cause an increase in site -erosion associated with storm runoff. Sediment laden ranoff entering nearly storm drains is capable of causing in,creased siltation. ^order to ensure that the project does not increase erosion, appropriate best management prac+_ces will be required as part ofthe project specifications. In addition, at the completion of the project, any disturbed exposed areas will be stabilized through the use of landscaping,hydroseeding and/or riu thing as appropriate. According to the Contra Costa County Flood Control District.Flood insurance Rate done Information.Map and the Resource Mapping system, Parker Avenue is located within a FENa Zone A floodplain. However, since Parker Avenue will be constructed at the sane location and grade as t ie existing Farmer Avenue, there will be no increased exposure of people or proper' to flooding.

The roadway connects the Sar.Pablo Avenue/Willow Avenme intersection,Just west of interstate 80,to the continuation of San Pablo Avenue nor#:?of Rodeo. The reconstractioi,of Parke-. .Avenue:s a comDonerA of the redevelop nei:t pian to re vita.ze Downtown Rodeo as a viable comarercial and me-eat oral hub. The plan, adopted in August of 1997,provides a huff and C1rva'ation analysis which assumes the reconstruction of Parker Avenue. The ex3Stiiag traff c counts and future volume projections provided in the plan were used as ttfte basis of the analysis provided in.this report. Traffic volumes are Dredicted to rertnain roughly constant unless unexpected bevels of development occur If unexpected levels of leve'oprnent do occur, the County vvil take' proactive is MSureS to ensure that Cir C;.Ieion impacts remain at a level t-hat iS SeSS than:sign`ificant(see below). ;,,urrentdy, Parker Aaersue is two l:ries in.each direction with enoughl, additionalwidth itch on-street parallel Y parking. In additiosn, a two-way'eft- aria lane is provided between 6 * Street and 7`'Stweet. T e barker Avenue proiect will reduce the roadway to one lane In each d:reCsSor. vvit�on-street parallel parking. The proposed configuration will reduce the number of graveled way lanes to on-,in earl, direction., with bicycle ,anes ariC shoulders f^vr parking, The two-way left turn lane would be replaced by a Center island rr edia"5 with designated left turn lanes at several intersections. _I.e justification for this neve design, is&,ree-fold. First,with tie const--action of the Cunr--digs Skyway Extension:nost local tree traffic and a large percentage of passenger car traffic can divert around the downtown Rodeo area thus reducing traffic volumes on Parker Avenue, Present day traffic counts and ature traffic models indicate that the capacity of a four-lane-facility is not currently necessary and will not be necessary into he future. Second, a two-lane facility with landscaping and a center rnedian featare is considered essential to the overall character of a new downtown area, Pedestrian and bicycle use will be rorty;ted,resulting in a 3"c":.ore desirable downtown Gore area. a hird, a downtown two-'ane facility assures a built-in traffic calming e2fe:Ct. Narrower pavement widths and landscaped sight lines will result in;.ower vehicle sneeds. The Parker Avenue Project will include the instailationof a.tra�IC signal at the intersection of IParker Avenue and 7th Street to address existing site distan ce issues associated with a wall installed as part of an, unrelated development project. she 7'1'Street si al will be interconnected(i.e,,timed)with other signals .n the area so no significant delays are expected to occur as a result of signal installatio n.

AC A1C AVENUE ' IRSECTiO REDESIGN NPACTS ANALYS S Pacific Avenue runs bet-ween Parker Avenue Crust north of 3rd Street) and the marina/recreational area north of Sawn Pablo Avenue. Currently, Pacific Avenue intersects Parker Avenue at an acute angle. Pacifzc .Avenue traffic is udder stop-control with a stop bar located approximately 50 feet north of the Third Street intersection. A n-arked pedestrian crosswalk is located approximately 85 feet behind tile stop bar for pedestrians wising to cross Pacific Avenue. A bus stop is located on the north side of Pacific Avenue. I he existing config=uration.has several disadvantages: s Pacific Avenue-motorists have to turn their heads greater than 90 degrees Lo see oncorning traffic on south bound Parker Avenue; Because the crosswalk is set back, motorists turning onto Pacific Avenue may not see pedestrians immediately; * Pacif c Avenue motorists have to tutu:their vehicles greater than 90 degrees to turn left onto no:,&und Parker Avenue; and * Third Street traffic (a oder stop-control)is required to not only negotiate Parker Avenue traffic (not understop�-contro`)but also Pacific Avenue traffic due to the close proximity of the Pacific Avenue and 3' Street n tersections. As a result of these design.deficiencies, a redesig b for the configuration of the Paeker/Pacif7c Avenue intersection is proposed as a component of the reconstruction.project I igure 4). The proposed reconflauration of t ie Pacific Avenue/Parker Avenue in'ersection provides improvement over tine existing configuration and addresses existing concerns, such as effective pedestrian circulation, as well as the skewed angle and close proxirnity to 3rd Street. The proposed redesign differs from the existing configuration it that only rig:t int s would be allowed tc and from Pacific Avenue. Crosswalk circulation is e_hanced under this option by moving the crosswalk along Parker Avenue and by providing a refuge median,breaking=up the crossing into two segments.

The Safeway shopping center is located or, the vast side ofFarlcer Avenue between "Street and 7'" Street. Two driveways on.. Rarer Avenue and ohne driveway on 7,`' Street provide genera:pSbhic access to the store. With the proposed median design, left taw nis in and oat of the PMESENegDecRevised.doc Page 30 o"36 September,2002 sate would be prohibited from the rorfre_-, driveway on Parker Avenue; however, full access would still be available frorn the southern driveway. This configuration: will accon=odate traffic to and.from either direction on Parker Avenue. The segment of Parker Avenue soul of the median and north of the southbound left-tum':an,e at 7"' Street will be strived as a two-way left-turn fare (TWLTL), as it is today. Withseveral com.rnercial driveways located on the west side of Parker Avenue, this will allow for left=min access to either side of .'ie street. Including the TVFLTL will allow space for motorists on Parker Avenue to wait for a gap ire oncoming traffic without stopping or significantly slowing dowry vehicles approaching from be hied. A gas station is located or,.the east side of Parker Avenue just south of4th Street. Driveways are provided on Parker Avenue and on 4th Street, Because the site is next to the Parker Avenue/4th Street intersection., fill access to and frorr either direction is available. The redevelopment plan designates commercial uses along most of Parker Avenue with some multi-fairly housing between arta an, d 4th Streets. Because the intersections cannot accommodate U-turns, access to most of' sites will be affected by the ir_stallation of a center median. Motorists cvi':l take a slightly more cireu-tous route or nark Blither from tr_e:r destination and walk. Street crossings, we.l-lighted and co itinuous sideways and street furniture, will minimize any pole.tial impacts associated with modified access to a level, of less than significant. Transit Access Western Contra Costa Transportation Authority(WestCAT j provides bus service in downtowmn Rodeo. Installation of a center median along Parker Avenue wall not affect the bus stop locations or the bus route, Sidewalk irniprovements near several bus stops are also planned as part of the Parker Avenue reconstruction, which will enhance conditions for transit riders. With the elimination of a second land in each direction, motorists wishing to pass a stopped transit bus would not have a separate lane to complete this maneuver. T' erefore,the roadway width will be a minimum of 20 feet from the outside edge of curb to the median or center striping at each bus stop to provide enough space for a vehicle to pass a stopped bus. The 20-foot wide lane will be a. dnia*.um of 120 feet long w4 fr a 120-foot curb painted red to prevent parking. Willa fhe inclusion of these design considerations,potential impacts to transit as a result of the project will be rri i l zed to a level that is less than sig.if cant. Emergency Vehicle Access Fire,medical, and police vehicles providing service to Rodeo need adequate access to all locations within Rodeo m the case of an emergency. Emergency vehicles car. use the entire intersection to crake U-turns (not just the left turn:lanes); therefore,only the largest of emergency vehicles (i.e., tractor/trailer fire trucks)will rot be abbe to negotiate U-turns at intersections along Parker Avenue. Since medical providers typically utilize vehicles teat can make U-"erns at the intersections (including ambulances and standard length fire trucks), impacts to emergency access for medical emergencies are not expected to be sighificant. To .=rove fire ernerge ycy response time, additior~a.1 fire hydrants will be installed along Parker Avenue to ensure t.at water is availabiv to emergency crews regardless of where the emergency vehicles are parked. Boti the fire department and the sheriffs office are located in downtown Rodeo;therefore,they should have little difficulty finding alternative routes sir e.e the area is set up as a traditional grid system with no one".-way streets. Medical services will approach f om either?- 0 or San Pablo Avenue and will have the capabiliy to rxake U-turas at the intersections in, order to access locations or,the west side oft arker Avenue. HESEE�egDecRevised.doc ?ago 31 of 35 septecrber,ZJG2 Staff from,both the medical and 4-re response teams have ir?dicated�.that they will i�iave adequate emergency access with the newly configured intersections and median, therefore, signilificant irnpacts to emergency response are not expected(personal cornm-unicatiorn with A. Biagi, Fire Chief,Rodeo-hierc ies Fire Protection District,May 30, 2002). Delivery Vehicle Access Because the Jecific Plarl.calls for=mostly conn"r ercial uses along Parker Avenue,silr" lar to what exists today, it is anticipated that s=mall delivery trues will inak--the majority of the truck trips it he downtown area. Such trucks will=not have diffin culty maneuvering the ctrgh intersections.

In=stallation of a center n iedian m. ay req uire sorne delivery ve'hicles to take a more circu'tous route to thre.r desti nation, however, although traffic patterns wary slightly clue to these modil ed=clines,total delivery truck volume.�xU not change from current levels. Based on the smaller size ofthese trucks(i.e.,bobtail de' very trucks such as overi3ight m afl, services or commercial supply trucks versus tractor-trail-;-tri=ads) and the consistent volume of delivery :rUuck traffic, :he iinnac,to adjacent residential neighborhoods is expected to be negligible. For trucks that will unload or street, identification of loading zones on Parker Avenue wizl provide space for trucks to poll out of the travel way and not impede traff c:now, Large truck t:ps are generated by the exis'dng Safeway store. The trucks enter the site on Parker Avenge iorths of the two general use driveways. The track access driveway extends to the loading dock behind, the grocery store and, continues around the site to 7th Street. Theproposed center median wouldbe in place adjacent to the truck entrance driveway, However, since most trucks co=ne from the direction of b-8C,there wi?l be negligible i=mpact because trucks would continue to enter on Parker Avenue as they do today and exit o: 7th Sheet. PARKING s PA ` S ANALYSIS Existing Parking Inventory An inventory of existing parking within the shady area,(defined as Parker Avenue from California Street to 7th S-eet and one to two blocks on either side ofParker Avenue)was provided by Contra Costa Ccunty and field verified by Fehr&Peers Associates. There are 654 on—street parking spaces and 420 off'-street parking spaces,totaling a supply of l,074 spares in the study area. On A.ixgzst 15, 2001, a block-bydv cck occupancy count was.conducted at 3:00 p.m.to determine the percentage of occupied spaces under typical afternoon conditions. :n total, 178 on-street spaces and 1.61 off-street spaces were occupied,representing a 27 percent occupa=ncy rate f€ar on-street spaces arida 38 percent occupancy rate for off-street spaces within tae study area,. Construction Impacts Dui~rg the reconstruction of Parker Avenue,vehicles will not be able to access portions of Parker. Avenue during different phases of construction;. 'Consequent`y,vehicles currently parking or. portions ofParlker Avenue wain be temporarKy displaced.. however, according to the August 200 1. count, there were few vehicles parked on Parker Avenue and plenty of avai=able alternate parking v ithin one to two blocks. I"°nerefore, a signbifica t parking impact is not expected during reconstruction of Parker Avenue. signage will be provided during constract`_on in order t0 he'p motonists locate alterniative pa=ring. H S NegDe-_Rmsed.dec Page 32 of 36 Septernber,2002 Project Iarplementation Impact As a result of i=Iernentatior of the reconstruction project, a total_of approxirn.ately 17 peKi:>g spaces will be removed due to the installation of roadway irnproverrents {narking bulb-outs} along Farber Avenue. This represents pproxi_nate y 3% of tl:e total on-street parking ava.i'_ab`e i:s the study area, Based on the sr nail percentage reduction and the ow percentage of use, removal off e 17 parking spaces is not expected to significantly impact parkc_ng availability in the downtown area. SUiv`IVA YOF Oi`✓'1VIEN EIS ' ITIGATION MEASURES Zecon^:rnendations for the rnitigation of potential traffic impacts are su=ar zed below. 1mplenientation of these rn-tigation measures will reduce potential transportation and traffic impacts to a level of less than 3igrSiflwailt. ' Left-Turn. QueueLengths linvact. Maximurn left-turn queue lengths for the 1"Street, 2nd Street, ?'d Street, 4`1'Street, 7t'Street, California Street, andSan.Pablo intersections with ParkerAvenue were determined. Under existing conditions, a maximum queue of 50 feet will be adequate. Traffic niodelin.g for predicted futurYe conditions also indicates ,that the proposed queue length is appropriate. However, depending on the uses that move in to the area,full build-out of the Specific Flan area may necessitate lunger turn pockets. Therefore, each location shall be monitored during ongoing Roder redevelopment to confi7-717 that this queue length remains adequate. Mitigation Measures Implement a tr4;ffzc monitoring program to assess the impacts of future redevelopment. The.Public Works Department Traffic Engineer will be responsible for monitoring queue lengths to determine whether congestion is an issue.

Following are responses to your comments (see your attached letter for corresponding question numbers); 1. Ali affected property owners were notified of the opportunity to attend a public . hearing -eld on March 14, 2000, regarding the utility a derg-ounding. At the hearing, all interested persons were provided°with the opportunity to voice any concerns re ardin the un rgrounding. Subsequently, the Contra Costa County Board of Swpervisors found that the undergrounding of utilities along. Parker Avenue Is in the ihterd t f ubli health, safety and welfare' and the underground utility district was formed. Any opposition° to the formation ofthe -underground utility district would need to have been voiced at the larch 4er hearing or in response to the CEQA docume' nt prepared for the formation of the utility district (posted at the County Clerk's office from March, 20, 2000, to April 20, 2000. However, your specific properties located at 222 Pacific Avenue and 224-226-228 Pacific Avenue do not fall within the underground utility district, therefore, you will not be .responsible for any utility conversions associated with the undergroundng project. 2, ReConstruction of Parker Avenue s a critical step in the revitafizatlon of Parker Avenue and downtown Rodeo and is one of several downtown Infrastructure irnprove:—:�ents identified in the Rtodeo Downtown/VV ate rfront Specific Plane ` 'he intent of the undergrounding and reconstruction project is to enhance the appearance and economic viability of the Farber Avenue downtown corridor. A traffic study prepared by Fehr & beers Associates Inc. anal zed the reconstruction of Parker Avenue to one lane in each d°rectioh between street and California Street with on-street parallel parking. The report determined ;hat capacity of the 'fir. Lawrence Leal December 18, 2002 Page 2 reconstructed roadway is expected to be adequate under existing and predicted future conditions. However, according to the study, possible future conditions including full build out of the Specific Plan area may necessitate longer loft tura pockets than currently designed. Therefore, each location will be monitored during ongoing Rodeo DowntownMaterfront redevelopment to confirm that this queue length remains adequate to allow for smooth flowing left tura miovernents, as well as effective throughput along Parker Avenue. The Public Works Department Traffic Engineer will be responsible for monitoring queue lengths to determine whether congestion is an issue. One of the expected benefits of the project is discouraging the use of Parker Avenue as an alternate route to 1-80. The goal of the proposed project is to create a pedekdan4dendly commercial and recreational corridor that would not serve as a convenient alternate for 1-80 commute traffic. Typically, projects that discourage non-local traffic from; using established community roads are generally considered beneficial. In the event thatl-80 is completely shut down, a two-[ane Parker Avenue would still accommodate overflow traffic, albeit with obvious delays. However, even if Parker Avenue remained a four-lane roadway, substantial delays could be expected in the event of a complete closure of 1-80. Analysis of closures on 1-80 is cuts de the scope of this CEQA document.

Following are responses to year comments (see your attaced e-mail Yl- comment inu Lers assigned'). 1. he ubiic Works Departinent haSi t ^c the m pactsof oing 'arcm ffour wanes is two lanes along Parker Avenue. As mentioned in our November 23, 1999 letter to you,. traffic n ud es were.conducted as part of the Rodeo Wate.;rc^U ownfo n Specific plan process. Results of those studies indicate that the proposed improvements will not hamper traffic flow on barker Avenue. In addition, traffic studied constructed for the Cummings Skyway Extension project analyzed 'traffic impacts `with ,alarker Avenue odeied as a two-lane roadway. Results of that study also indicated that capacity along Parker Avenue would not be an issued 2. The Chamber ofcr'merce has been involved in the plan ning process and t-ac had arnple opportunity to bring up opposition to the project. The Chamber of Commierce -has no ca.ed concerns :+h the proposed raiec". :Ahe purpose of the proied is to enhance the appearance and economic viability of the existing Parker.Avenue commercial strip. To help achieve this coal, the roadway will be reconstructed to one [ane in each,; di;ec¢ion between 76" Street and California Street. Although this modification will reduce the available capac€ty of the roadway, a traffic study prepared by 'Fehr & Peers Associates Inc. (March, 2092) analyzed tide reconstruction and determined that capacity of the reconstructed roadway is expected to be adequate under existing and predicted future conditions. However, according to the ]tudy, possible 4: a't€are c n ILlons, inCluding full build-oi : of thepec'fc Plan area, y necessiiate longer left turn pockets than currently proposed. Therefore, each iocation will be monitored during on-going Rodeo .f"DowntC7wnNI alerfront redevelopment to con", "% that this queue length remains adequate to a€lour or smooth flowing left turn movements, as well as effective throughput along Parker Avenue. Tlhe Pubiic Works Department Traffic Engi;-,eer will be responsible for mo;;itoring queue lengths to determine whether concestion is an issue. 4. A number of roadway improvement options were considered early n the planning stages of the writer Avenue Reconstruction Project, These options included repaving the existing roadway, closing Pacific Avenge between 2nd and 3I Streets, modifying Sari Pablo Avenue between Pacific and Parker Avenues, and rerouting Parker between 3`d Street and San Pabic Avenue along the Railroad Avenue corridor.
