BACKGROUND The City Council and Planning Commission has met over 20 times in Joint Workshops and in separate meetings between January 2004 and the end of 2006 to discuss circulation and land use issues. Out of those meetings came an agreement on a "working draft" circulation system and a preferred land use plan. The "working draft" circulation system consists of the existing (through 2006) roadway network and future improvements (changes to intersections, road widenings, and road extensions) as described in Attachment 1 to this staff report. The preferred land use plan consists largely of build out of the land use map adopted with the 1996 General Plan with the addition of approximately 1,400 additional residential units and some "place holder" assumptions for commercial and residential development of east Pleasanton properties (former quarry areas), pending the preparation of a Specific Plan for that area. A listing and map of future residential development is included in Attachments 2 and 3. A summary of additional residential development at build-out, as well as a summary of additional commercial, office, and industrial development is included with the description of the traffic model in Attachment 4. DISCUSSION Existing Conditions: A comprehensive review of existing traffic conditions was provided to the Planning Commission and City Council in a joint workshop on March 22, 2005. The staff report from that meeting is included as Attachment 5 to this report. It should be noted that data from the March 2005 staff report is drawn from the 2003 Baseline Study. Because that data is now over three years old, new traffic counts were taken in Spring 2006 and this latest data has been used to calibrate the model for the analysis discussed in this staff report. The 2006 model data shows: In the morning peak hour: . One intersection is operating at LOS E (Bernal Ave and 1-680 SB off-ramp) . Four intersections are operating at LOS F (Foothill Rd and Foothill High School; Main St and St John/Ray St; First St and Vineyard Ave; Bernal Ave and Main St) Excluding Downtown intersections (which are not held to the LOS "D" standard) one intersection operates at LOS E and one intersection operates at LOS F in the morning peak hour. In the evening peak hour: . Three intersections are operating at LOS E (Hopyard Rd and Stoneridge Dr; Santa Rita Rd and Valley Ave; Bernal Ave and 1-680 SB off-ramp) . Six intersections are operating at LOS F (Hopyard Rd and Owens Dr; Hacienda Dr and Owens Dr; EI Charro and 1-580 EB off-ramp; Valley Ave and Koll Center Pkwy (S); Main St and St John/Ray St; First St and Ray Street! Vineyard Ave) Excluding Downtown intersections, three intersections operate at LOS E and four intersections operate at LOS F in the evening peak hour. Modeling Process: Summarized briefly, the model utilizes a combination of the City's existing and future land uses, and the existing and future roadway network to project traffic volumes. The model routes traffic as necessary to produce "Existing" and "Build- Page 2 of 6
