THE SETTING 1.1 Project Description The developer proposes the contruction of a professional office building containing 31,400 square feet of gross floor area. The site is located on a parcel of land on the west side of S. Bascom Avenue, between Apricot Avenue and Campbell Avenue, in Campbell. The development is city project No. S 83-19. 1.2 The Existing Transportation System Bascom Avenue is a six-lane arterial street that runs parallel to the Route 17 freeway between Los Gatos and San Jose. The section of Bascom Avenue adjoining the site has a continuous two-way left turn lane to facilitate left turns in and out of the numerous driveways along this section of the street. In the future, a median island may be installed in Bascom Avenue. Union Avenue is a four-lane arterial street in San Jose and a two-lane arterial street north of Bascom Avenue in Campbell. Campbell Avenue is a four-lane arterial street west of Bascom Avenue and a two-lane residential street east of Bascom Avenue. Public Transportation is provided by the Santa Clara County Transit System. Local bus service is available on Bascom Avenue and on Campbell Avenue. Express bus service is available on Bascom Avenue south of Campbell Avenue and on Campbell Avenue west of Bascom Avenue. 2. TRAFFIC IMPACTS 2.1 Trip Generation and Distribution Trip generation for the project has been calculated using rates given in the Transportation and Traffic Engineering Hand- book, 2nd Edition, for general office buildings. Table 10-22 from the handbook, Vehicle Trip Generation of Urban Land Use, is attached as Exhibit A. Trip generation rates are 12.3 daily trips per 1000 square feet of gross floor area, 2.3 AM peak hour trips and 2.2 PM peak hour trips per 1000 square feet of gross floor area. Based on these rates, the project will generate 386 daily trips, 72 AM peak hour trips and 69 PM peak hour trips. 1 Project generated traffic has been distributed to the local street system in accordance with existing travel patterns. Project traffic assignment for AM and PM peak hour traffic is shown on Figures 1 and 2 respectively. 2.2 Project Traffic Increases Project traffic increases on Bascom Avenue will be as follows: Bascom Avenue Existing Traffic* Project Traffic Ex + proj . Traffic % Increase N. of site AM Peak Hour PM Peak Hour 1941 3258 14 13 1955 3271 0.7% 0.4% S. of site AM Peak Hour PM Peak Hour 1941 3258 28 26 1969 3284 1. 4% 0.8% * From Counts furnished by the city of Campbell, made on July 30, 1981, at the Campbell Avenue-Bascom Avenue intersection, and with a 1.2% per year growth factor added. Project traffic increases on Bascom Avenue are less than two percent in the AM peak hour and less than one percent in the PM peak hour. Note that actual traffic volumes on Bascom Avenue south of Campbell Avenue are 68 percent higher in the PM peak hour than in the AM peak hour. 2.3 Intersection Levels of Service Intersection levels of service have been calculated for PM peak hour traffic conditions. Clearly, these are the controlling conditions. For the intersection of Bascom Avenue and Campbell Avenue, the city furnished level of service calculation sheets that had been used to evaluate traffic conditions from development of the Prometheus project. These sheets show conditions as follows: 1. Existing Traffic: 2. Existing Traffic Projected to 3. With Traffic from the Ainsley Project Added: 4. With Traffic from 460,000 sq. of additional development {Prometheus Project}: Level of Service 93% of Level of Service E 1986: 99% of Level of Service E 100% of Level of Service E ft. 104% of Level of Service E Condition 2 We calculated two additional conditions per information received from the city of Campbell's Public Works staff (Keith Manley.) : Condition Level of Service 5. With mitigation of Condition 4 by installation of a double left turn lane on Northbound Bascom Avenue: 95% of Level of Service E 6. With traffic added from Project No. S83-l9: 95% of Level of Service E Calculation sheets are included in the report appendix. These calculations show the project traffic will have no impact on levels of service at the Bascom Avenue-Campbell Avenue inter- section. For level of service calculations at the intersection of Bascom Avenue and Union Avenue, we used traffic counts supplied by the City of Campbell, and approved development trips for other developments supplied by the City of San Jose. Since this is a city of San Jose intersection, calculations were made according to San Jose's approved methods. Calculation sheets, included in the appendix, show as follows: Condition VOlume/Capacity Ratio & Level of Service Percent Increase Critical Movements Existing Traffic 0.851 D Exist + Apl?r9Y~~ Deve19nmp-n1;j~ Q el;iS D ~xist + Annr + ~rQj~~~ S~J-]9.._Q,R76 .".-V o.oo&/i. with Traffic added from the Prometheus development: 0.890 D 1.2% 0.5% 2.2% TQf>~p("rtlr.lllrt+;nn ~'hnw that nroject traffic will nrd- n;nr<=> .s siC]ni f; ("'iiln't imr::ll""+ on Levels of ~l='nT; ("I=' rt+ t'hP- intersection of Ba~("nm AVP-nllP rtnn Tln;nn Avenue. 2.3 Summary of Project Traffic Impacts Levels of service during the PM peak traffic hour at the analyzed intersections will not change due to the addition of project traffic. Intersection levels of service will remain at Level of Service E at the intersection of Bascom Avenue and Campbell Avenue, and at Level of Service D at the inter- section of Bascom Avenue and Union Avenue. 3 CAMPBELL A VENUE 8 t ! 3 _1 2- 10 t l 4 B APRICOT AVENUE ..u ::::> z ..u > < z o H z :::> 8 t ~ 20 ~ ~ ~ "\ 7 ~ I~ ~ J 18 DRY CREEK ROAD -""2 l~ FIGURE 1 AM PEAK HOUR PROJECT TRAFFIC CAMPBELL AVENUE 2 , 1 8 -2 1- 3 t ! 10 B APRICOT AVENUE ~ :::> z ~ >- <t: Z o ...... z :::> 20 i ~ 6 DRY CREEK ROAD '" 2 --... 1 FIGURE 2 PM PEAK HOUR PROJECT TRAFFIC APPENDIX A Traffic Counts (AM & PM) : (4 sheets) Bascom Ave. - Campbell Ave. Bascom Ave. - Union Ave. Approved Trips Inventory (city of S.J.): (1 sheet) Bascom Ave. - Union Ave. Intersection Levels of Service: (6 sheets) Bascom Ave. - Campbell Ave. Intersection Levels of Service: (4 sheets) Bascom Ave. - Union Ave. , ,.,. ii' ,j ( , I A ~ ,_.- - d - ~ () ('(\ r'\ f'- -.9 0 ('(', c;-- ~ ~ r- O(j - ~ >- \J' ('I\ l'- ~ ~ == - r r . i- - '\' 0 (I) J \l) 0::' t- ~I ~ ~ " ~ WZ~ 'D \II \rI <:1:l "- "- ~ ~ M l' ~ ~O~ N "- N N "- "- \91 :::::> ~ .-- - ! <l ,J ~ai~ cri Il \l t;) l:l "I I I- \l \J .

Szewczyk Nowack & Associates, Inc. 477-A Gianni Street Santa Clara, CA 95054 SUBJECT: PLANS FOR STORM DRAINAGE FOR MITCHELL MERCER & COMPANY OFFICE CENTER AT 2155 SOUTH BASCOM AVENUE, 'McG(23b) Dear Mr. Szewczyk: We have reviewed subject plans. We find the drainage plans for both onsite and offsite to be acceptable, I~heet 1 of 1 sheet~'of the Public Storm Drain sheet needs two corrections: 1) The profile shows 1921 M.H.#2 and M.H.#3. This should be 1191, as shown on the plan view. 2) The approval and signature 1 ines for the City Engineer should be removed. This installation is considered to be a part of the off- site improvements to be installed by the developer. Plan approval and authority to construct will be given via the Public Works per- mit process, Please be aware that separate Public Works permits will be required for the offsite storm drain work and for offsite surface work. Please call the undersigned if there are questions. Very truly yours, Joseph Ell iott Director of Public Works David N. ~~ar Associate Civil Engineer DNV/le cc: DOn King, Engineering Technician 20 FOOT PRIVATE STORM DRAIN EAS:EMENT TO BE GRANTED BY JAMES BAKER, :RT UX TO MITCHELL MERCm COMPANY UESCRIPTION All of that certain real property situate in the City of Campbell, County of Santa Clara, State of California, and being a strip of land 20 feet in width, described as follows: The westerly 270.00 feet of the southerly 20 feet of that certain pa.rcel of land granted to James Baker, et ux by C.
