6h Review of Crellin Road Pilot Proaram and consideration of soeed bumDS and radar soeed sians. (SR 05:223) Mike Tassano, Assistant Traffic Engineer, presented the staff report. Mr. Sullivan believed the speed lumps on Crellin Road resulted in a decrease of speeding with fewer vehicles using this roadway and more vehicles shifting over to Arbor Drive with an increase in exceeding the speed limit. He asked if the critical speed on Arbor Drive would decrease if speed lumps were installed? Mr. Tassano said yes. Mr. Thorne asked if less speed lumps would be as effective on Crellin Road? Mr. Tassano said no. He believed the spacing between the six speed lumps on Crellin Road was adequate in suppressing the critical vehicle speed. Ms. McGovern noted that the staff report mentioned the latest traffic count with radar speed signs was taken in July when school was not in session. She wanted staff to conduct another traffic count with radar speed signs when school was in session because she believed speeding is more common during this time. Mayor Hosterman recalled that a radar speed sign was mounted at the top of Touriga Drive at one point during the school year. Mr. Tessano said a radar speed sign was mounted at the top of Touriga Drive during the school year and the before and alter speed studies showed that with a residential location the variance was smaller, whereas, installation of radar speed signs on West Las Positas is more significant. Ms. McGovern referred to the City's Traffic Calming Program brochure, which mentions that maintenance agreements with homeowners are an option for deferring the City's cost of such options. She asked if a homeowners association would be charged for maintenance. Mr. Tassano said staff has not assessed any maintenance charges to date. Mr. Fialho said there is a potential of establishing a district or a mechanism that would ensure there is a standard applied for maintenance requirements, which would be related to traffic circles and the landscaping within them, medians and other items listed in the toolbox. Ms. McGovern asked if traffic lights with radar would be used more frequently in the Traffic Calming Program? Jeff Knowles, Deputy DirectorfTransportation, noted that when intersection measures are discussed in the General Plan update process, there are four locations where Council will hear the proposed removal of existing four-way stops and replacing them where speed is an issue with speed sensitive traffic signals. Mr. Brozosky referred to the staff report, which indicated that 2/3 of the Crellin residents liked the speed lumps and about 50 percent believed it was not enough.
