hardscape includes an ADA compliant wheelchair cutout and that ADA ramps now cost approximately $5,500 each. Mayor Thorne closed public comment. Traffic Engineer Tassano explained that the extension of Stoneridge Drive presents a number of changes to the circulation pattern in general, one of which is a reduction in the traffic volume turning right onto southbound Santa Rita as a result of the third and likely more convenient option of continuing down Stoneridge into Livermore is made available. He also explained that the bus pullout would be shifted over so as to be almost completely behind the adjacent sound wall. He said he did not anticipate an obstruction related to the bus stop or any decreased dealy in lefthand turning abilities but would continue to monitor the location. Vice-Mayor Cook-Kallio asked whether the intersection of Suttergate and Santa Rita is troublesome in terms of accidents and whether preventing lefthand turns at this location would be appropriate. Mr. Tassano said the collision pattern there is not as poor as in locations where they have elected to install medians preventing lefthand turns. He said that if the collision pattern were to continue or increase, that sort of improvement would be preferrable to a full traffic signal. MOTION: It was m/s by Cook-Kallio/Pentin to approve plans and specifications, award and authorize the City Manager to execute a contract with Carone and Company, Inc. in the amount of $1,025,523.40 for the Staples Ranch: Stoneridge Drive and Santa Rita Road Intersection Improvements project, CIP No. 115034; authroized the Director of Community Development to approve and execute change orders in an amount not to exceed $102,550 and the transfer of $150,000 from the Bus Pullout — Santa Rita Road Stoneridge Drive project CIP 105034 to said CIP 115034. Motion carried by the following vote: Ayes: Councilmembers Brown, Cook-Kallio, Pentin, Mayor Thorne Noes: None Absent: One Vacancy 11. Introduction of Ordinance to amend Title 11, Chapter 11.20, Section 11.20.010 of the Pleasanton Municipal Code changing various speed limits on City of Pleasanton streets as part of the speed limit review and update of engineering and traffic surveys Mr. Tassano presented the staff report. He explained that the California Vehicle Code establishes a select number of universal speed limits, generally 25 mph on residential streets, 65 mph on freeways, 55 mph on two lane roadways, and 15 mph in alleyways. For roadways not falling under these specific requirements, the code allows local agencies to determine the appropriate speed through the preparation of an engineering traffic survey that must be updated every 7 years. The requirements outlined in the code are intended to reflect the premise that most people observe a reasonable speed and that 80% of accidents are caused by the fastest 15% of drivers. The primary purpose of the traffic survey is to determine critical speed, as represented by 85th fastest speed out of 100 vehicles. Critical speed is then rounded to the nearest 5 mph increment, with the exception of certain unusual elements that allow another 5 mph reduction to the posted speed. The code also establishes the difference between local and arterial roadways and provides guidelines in terms of where the City might best adjust speeds when transitioning between these areas. He noted that any posted speed limits not complying with these guidelines are not enforceable via radar. Mr. Tassano reported a total of 130 reportable segments within the City, 25 of which are discussed in the attached report. He noted that the statistics provided cover a number of years and explained that while he would normally bring changes forward more frequently, there have been changes to state law City Council Minutes Page 6 of 10 March 5, 2013
