DESCRIPTION: California Vehicle Code (CVe) Section 22358 provides that a local agency may, by ordinance, adopt a speed limit which is "appropriate to facilitate the orderly movement of traffic and is reasonable and safe" CVC Section 40802 provides that in order to use radar for enforcement of speed limits on roadways which do not meet certain conditions, a local agency shall conduct engineering surveys to support the posted speed limits. The conditions under which engineering surveys are NOT required are: roadway width of 40 feet or less, less than one half mile of uninterrupted length, and not more than one lane in each direction. Neither Gleason Drive nor Grafton Street meets all three conditions, and engineering surveys are therefore required. On December 7,2004, the Dublin City Council accepted Gleason Drive as constructed between Tassajam Road and Fallon Road, as well as the portion of Grafton Street constructed between the boundary of Dublin Ranch Phase I and Gleason Drive. It is now appropria,te for the City Council to review the --------------------~-----------------_.--~-------------------- g:\"8"""';"'. gleason It. grafton spe<d limits COPIES TO: Co . 3 19J~ ITEM NO. engineering survey results and adopt speed limits for the new portions of both Gleason DrivJ ~ ~rafton Street. Gleason Drive Speed surveys were conducted for segments between Tassajara Road and Grafton Street and between Grafton Street and Fallon Road. The 85tl¡ pereentile or eritieal speed was measured at 44 mph between Tassajara Road and Grafton Street and at 46.3 mph between Grafton Street and Fallon Road. The 85th percentile or critical speed is generally regarded as a "safe" speed. Eighty-five percent of the vehicles in the survey sanlple were traveling at the eritieal speed or less. An engineering survey also evaluates roadway conditions sueh as geometrics, land use, and proximity to schools. Based on the measured critical speed and the existing speed limit of 40 mph on Gleason Drive west of Tassajara Road, Staff feels that a speed limit of 40 mph is appropriate on both segments of Gleason Drive between Tassajara Road and Fallon Road. Grafton Street The new portion of Grafion Street was extended from the Tract 6959 boundary to Gleason Drive. Within Tract 6959, Grafton Street is a residential neighborhood street. The Grafton Street extension serves the new Fallon Middle School, wbieb is presently under construction. Since this portion of Grafton Street exceeds 40 feet in widtb, an cngineering survey is required. The 85th percentile or critical speed was measured at 35 mpb. Since this street is in proximity to residential areas and serves the frontage of a school, the survey recommends a speed limit of 25 mph as appropriate. Staff recommends that the City Council eonduet a public hearing, deliberate, waive the reading and introduce the Ordinance (Attacluncnt 1) approving speed limits for Gleason Drive between Tassajara Road and Fallon Road, and for Grafton Street between Gleason Drive and Antone Way.
