DISCUSSION There are 107 segments of roadway in Pleasanton that are required to have valid Engineering and Traffic Surveys completed. Of those recently reviewed, one is recommended for an increase in speed limit and one segment, without a current posted limit, will have a speed limit established. Stoneridge Drive between Kamp Drive and Trevor Parkway Currently, Stoneridge Drive has a 35 MPH posted speed limit between Kamp Drive and Trevor Parkway. The critical speed and roadway conditions do not allow for a 35 MPH speed limit. Our Police Department is unable to enforce the current speed limit by radar as it is a speed trap under the California Vehicle Code. The change to 40 MPH is necessary for speeding citations that are issued in that area to be upheld in court. This section of Stoneridge Drive consists of four lanes divided by a raised concrete median. Parking is not permitted on either side of the roadway but there are bike lanes available for emergency parking. The alignment of this roadway is level with a slight horizontal curve at the midpoint of the segment. The critical speed was measured at 44 MPH. The recommended speed limit is 40 mph. While the critical speed suggests a posted limit of 45 MPH, the California Vehicle Code 21400(B) allows the posted limit to be down to 40 MPH, but prohibits the local authority from reducing the speed limit any further for any reason. The recommended speed limit is 40 MPH. El Charro Road El Charro Road does not currently have a formal speed limit. The segment consists of four divided lanes north of the 1-580 eastbound off-ramp, eight divided lanes (five southbound and three northbound) between the eastbound off-ramp and Stoneridge Drive, and two divided lanes south of Stoneridge Drive. Parking is prohibited on both sides of the roadway. There is a slight horizontal curve both north of the 1-580 eastbound off-ramp and south of the 1-580 westbound ramp. There are also vertical curves that lead to the top of the 1-580 overpass. The critical speed was measured at 41 MPH. The recommended speed limit is 40 MPH. The critical speed supports this recommendation.
