The Assessment evaluates the change in delay with "all sites" as opposed to evaluating the impact of the 25 housing sites individually. Therefore, some interpretation is required to identify which housing sites contribute to an intersection's increased delay. The Assessment shows that depending on the timeframe analyzed, anywhere between four and nine intersections operate at an unacceptable level of service in the future, if all 25 sites were to be developed at maximum density. It is important to note that many of these intersections operate at an unacceptable level of service even without the Housing Element update; in these locations it is important to evaluate the relative increase in delay caused by the housing development. Of the nine intersections that fail the level of service threshold established in the General Plan, the four most impacted by the Housing Element include: 1. Santa Rita Road at Pimlico Drive / 580 Eastbound ramps; 2. Santa Rita Road at Stoneridge Drive; 3. Santa Rita Road at Valley Avenue; and 4. Stoneridge Drive at Stoneridge Mall Road. The other five intersections include: 1. Hopyard Road at Owens Drive; 2. Sunol Boulevard at 1-680,- 3. -680;3. Stanley Boulevard at Valley/Bernal Avenue; 4. Hopyard Road at Stoneridge Drive; and 5. Hopyard Road at 1-580 Eastbound ramps. These five have modifications identified in the Traffic Impact Fees (TIF) to return them to an acceptable level of service (though the Assessment evaluates level of service prior to any modifications). The four intersections impacted by the Housing Element experience an increase of more than 10 seconds per vehicle with the Housing Element update. Some sites, while proximate to these intersections, result in a decrease in traffic due to existing uses on the site that generate more traffic than a hypothetical housing project. Area 16 (Tri- Valley Inn) and Area 18 (Valley Plaza) are both examples of sites where this occurs. The sites most directly associated with the increase in vehicle delay include: • Area 11 (Old Santa Rita): this site was evaluated with a maximum of 1,311 units which adds 730 trips to the PM roadway network. These added trips increase delay to both Santa Rita Road at Pimlico Drive, and Santa Rita Road at Stoneridge Drive. • Area 20 (Boulder Court) and Area 21 (Kiewit): these two sites have a combined count of 1,138 units which add 634 trips to the PM roadway network. These trips impact the intersection of Santa Rita Road and Valley Avenue. It should be noted, however, that the "East Pleasanton Specific Plan Assumptions" as reflected in the Citywide Traffic Model were included in addition to these sites and reductions in those future assumptions (which include up to 530,000 square feet of future industrial development) would lessen the sites' impacts.
