Wayne Rasmussen July 25, 2013 /1145' Page 9 of 11 Boulevard. Traffic traveling on El Charro Road, destined for Stanley Boulevard would also increase their travel distance by traveling through the EPSP. Option 4 would provide the most direct connection between El Charro Road and Valley Avenue, via both Busch Road and Boulder Street (requiring left and right turns depending on the direction of travel). Option 1 provides the least direct connection between El Charro Road and Valley Avenue. The curvilinear network has disadvantages for pedestrian and bicycle travel through the EPSP by increasing the distance between uses, potentially discouraging non-automobile trips. The curvilinear nature of the primary streets can also result in more cul-de-sac streets which potentially further increases walking/biking distances if they are not designed to provide a non- motorized connection. Curvilinear streets create angled intersections that can have sight distance and other operational issues and can also result in irregularly shaped parcels that can be difficult to fully utilize. Two Options (Option 1 and 4) include a crisscrossing of Busch Road Boulder Street, with Boulder Street becoming the more northerly roadway. This creates a circuitous roadway network and could increase the level of traffic turning at each of the resulting intersections, potentially requiring additional capacity for vehicles. Option 1 also includes a T-intersection of Boulder Street into Busch Road at a curve in the roadway. A likely fourth leg of this intersection would serve a commercial parcel. Right-turns on red lights may need to be prohibited at this intersection for some movements due to sight distance constraints, reducing its overall capacity. The intersection would be approximately 1/4—mile from the El Charro Road at Busch Road intersection. Options 5 and 6 include a curved Boulder Street that intersects with Busch Road. It is anticipated the resulting intersection would need to be signalized under either option. In Option 5, the potential connection is fairly close to a trail crossing that may also need to be signalized. In Option 6, the Boulder Street connection at Busch Road is approximately 750 feet from the El Charro Road at Busch Road intersection. The final roadway layout should consider how closely spaced intersections would operate as vehicle queue spillback from one intersection could affect the operations of the adjacent intersection. Modifying roadway network Option 6 to relocate the intersection of Boulder Street at Busch Road approximately equidistant between the trail crossing and El Charro Road would permit better
