Under existing conditions, long southbound traffic backups occur during the peak afternoon school and <br />commute hours extending north from the intersection of Main Street and Ray Street (which operates at <br />LOS F), over the Arroyo Del Valle bridge, and through the intersection at Del Valle Parkway. The 1996 <br />General Plan assumed that Stanley Boulevard would be widened to provide two westbound left turn <br />lanes and one through/right lane. To help ease existing and future traffic congestion, the #1 southbound <br />through lane at Stanley Boulevard could be converted to a second southbound left turn lane. This would <br />eliminate the existing southbound merge of two lanes down to one lane over the Arroyo Del Valle <br />bridge, and help reduce congestion at Main Street and Ray Street by drawing away some of the <br />southbound left turn traffic. <br /> <br />Santa Rita Road at Stoneridge Drive <br />Mitigation - Construct a southbound right turn lane, convert the #1 northbound through lane into a left <br />turn lane (Alternatives A & B), convert the #1 eastbound right turn lane into a third through lane <br />(Alternative C). <br />All Year 2025 alternatives assume the construction of a new southbound right turn only lane at this <br />intersection. <br /> <br />Alternative Networks A and B assume that the #1 northbound through lane will be restriped as a new <br />left turn lane. About 30% of northbound traffic tums left from Santa Rita Road to Stoneridge Drive <br />during both the peak morning and evening commute periods. This results in significant delays, with <br />drivers often waiting for multiple green lights to get through the intersection even under existing <br />conditions. The two remaining northbound through lanes are forecast to operate at LOS D or better <br />through the year 2025. <br /> <br />Alternative C includes the Stoneridge Extension, which reduces the northbound left turn and eastbound <br />right turn volumes at this intersection. Congestion and delay is reduced in this Alternative by <br />maintaining the existing three northbound through and double left turn lane configuration, and <br />converting the #1 eastbound right turn lane (one of two eastbound right turn only lanes) into a third <br />eastbound through lane. This also improves pedestrian safety in the south crosswalk. <br /> <br />Santa Rita Road at Valley Avenue <br />Mitigation - Add a third southbound and second westbound left turn lane <br />All traffic model forecasts of future traffic conditions assume that a third southbound left turn lane and a <br />second westbound left turn lane will be constructed at this intersection. This project was included in the <br />1996 General Plan and has been in design since the year 2000. This project involves reconstructing the <br />existing raised medians on Santa Rita Road and widening portions of Valley Avenue east of the <br />intersection. Funding for this project primarily comes from excess NPID traffic mitigation funds. <br /> <br />Stanley Boulevard at Valley/Bemal Avenue <br />Mitigation - Widen Stanley Boulevard to accept a third eastbound through lane <br />Widening Stanley Boulevard by one lane when the now vacant southeast corner property develops will <br />significantly reduce delay at the intersection. This will allow the lightly used eastbound right turn only <br />lane to be converted into a through/right option lane. Having three eastbound lanes at this intersection <br />was included in the 1996 General Plan. <br /> <br /> <br />
