Key roadway segments in Spring Lake including Parkland Avenue and Marston Drive will extend and connect into the proposed WRTP Plan Area as described in Chapter 4 of the Specific Plan. Buffered bike lanes and off street Class 1 bike trails will similarly extend into the plan area along Marston and Parkland between Harry Lorenzo and Road B (see Land Use Plan). Parkland Avenue will eventually extend west over Highway 113, but the overpass extension will not take place until future build out of Specific Plan areas “SP-1B” or “SP-1C”, located west of Hwy 113, as described in the 2035 General Plan. All segments of CR25A between CR102 and Hwy 113 will be completed with Plan Area build out, or earlier, including the extension of the urban forest trail on the north side of CR25A.
Circulation planning for the Woodland Research and Technology Park Plan Area took into account potential increased traffic volumes that may impact the Spring Lake neighborhood. Where existing roadway networks within Spring Lake were designed to extend into the Tech Park plan area (Parkland, Marston) roadway design incorporates a variety of design features including roundabouts, signalized intersections, narrow roadway widths, enhanced pedestrian crossings, and on street parking and bike lanes that have the effect of reducing vehicle speeds.
A Traffic Impact Study (“TIS”) was completed for the project in April 2021, which analyzed Level of Service impacts for road segments and intersections throughout the WRTP Plan Area as well as in Spring Lake as a result of Plan Area build out. Level of Service or LOS, is a term used to quantitatively describe the operating conditions of a roadway based on factors such as speed, travel time, and delay. The TIS demonstrated that build out of the WRTP Plan Area will not result in roadway capacity issues in Spring Lake, due to the fact that arterial roadways in Spring Lake were sized in anticipation of future build out of the WRTP to the west. There are two intersections adjacent to Spring Lake that do not meet the General Plan LOS policy goals, the Gibson Road/Pioneer Avenue and Gibson Road/Harry Lorenzo Avenue/bourn Drive intersections. However, these intersections were already projected to not meet the General Plan LOS policy goals with buildout of the south area.
While traffic volume is expected to increase with the build out of Spring Lake and the build out of the WRTP Plan Area, design and traffic calming measures will help maintain appropriate vehicle speeds within both the Tech Park and Spring Lake neighborhoods and discourage cut through traffic through existing and future local roads and neighborhoods.
One of the more extensive circulation related improvements in the Plan Area will include modification to the CR25A / Hwy 113 interchange to accommodate increased traffic volumes and peak hour trips at this facility. City staff will continue to work with Caltrans on the timing, design and construction of necessary improvements.
