DESCRIPTION: This is the second reading of a proposcd ordinance that was introduccd at the January 18th City Council meeting. California Yehicle Code (CYC) Section 22358 provides that a local agency may, by ordinance, adopt a speed limit which is "appropriate to tacilitate the orderly movement of traffic and is reasonable and safe," eye 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 cngineering surveys to support the posted speed limits. The conditions under which engineering surveys are NOT required are: roadway width of 40 fcet 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 arc thcrefore required. On December 7,2004, the Dublin City Council accepted Gleason Drive as constructed between Tassajara Road and Fallon Road, as well as the portion of Grafton Strcet constructcd between the boundary of Dublin Ranch Phase I and Gleason Drive. It is now appropriate for the City Council to review the ø______________________________________________________________ g:\agenmisc\a.gst gleason & gralluD speed limits COPIES TO: ITEM NO.~ liJ'oL !Y engineering survcy results and adopt speed limits for the new portions of both Gleason Drive and Grafton Street. Glcason Drive Speed surveys were conducted for segments betwecn Tassajara Road and Grafton Strcct and bctween Grafton Street and Fallon Road. The 85th percentile or critical 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 sample were traveling at thc critical speed or less. An engineering survey also evaluatcs roadway conditions such 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 believes that a speed limit of 40 mph is appropriate on both segments of Gleason Drive bctwecn Tassajara Road and Fallon Road. Grafton Street The new portion of Grafton Street was extcnded from the Tract 6959 boundary to Gleason Drive. Within Tract 6959, Grafton Street is a residential neighborhood strcet. The Grafton Street extension scrves the ncw Fallon Middle School, which is presently under construction. Since this portion of Grafton Street exceeds 40 fcet in width, an enginccring survcy is required. The 85th percentile or critical speed was measured at 35 mph. Sinee this strcet is in proximity to residcntial areas and serves the frontage of a school, the survey recommcnds a speed limit of 25 mph as appropriate. Staffrecommends that the City Council conduct a public hearing, deliberate, waive the reading and adopt the Ordinance (Attachment I) approving speed limits for Gleason Drive between Tassajara Road and Fallon Road, and for Grafton Street between Gleason Drive and Antone Way.
