Wandzia Grycz November 7.1996 t will cost about S52,000 to install a total of 12 new humps, and to remove the hump on Sybil and all four traffic circles. This work can be paid for by available Development Fees for Street Improvement (D.F.S.I.) funds, which has been allocated for neighborhood traffic control devices in Fiscal Year 96-97. Staff requests that the Citv Council authorize the use of these funds. Staff also recommends that the Council considers the guidelines presented at the end of the attached report. These guidelines may serve as a basis for evaluating future programs of traffic calming devices. However, each street segment and neighborhood has concerns that need to be evaluated independently. SUMMARY OF ATTACHED REPORT In September, 1995 staff recommended a pilot program to place one speed hump and traffic circle on Joaquin. Juana, Dolores and Maud Avenues. In response to concerns from residents on Estudillo and Sybil Avenues. the City Council directed staff to expand the program to place a traffic circle on Estudillo and one speed hump on Sybil. During the planning of the pilot program. the community and the City Council established both the goals for the program as well as the constraints on what the program could do. The goals were to reduce the speeds of all traffic in the vicinity of the humps and circles without the need for added police speed enforcement, to determine whether these kinds of traffic controls were effective in reducing speeds. and to determine how these controls would be received by residents. The program also gave staff the opportunity to test the appropriateness of installing a traffic circle on an arterial (Estudillo) with over 13.000 vehicles a day. and a speed hump on different arterial (Sybil) with almost 7,000 vehicles a day. The constraints were that 1) peed reductions should be accomplished without significantly impacting emergency access and 2) the circles nd humps should not result in significant shifts of traffic volume among the streets in the neighborhood. including Estudillo, a residential arterial. The pilot program ,vas not directed to reducing_ speeds along_ the entire street, but just near the devices. The ten month pilot program is complete, and all data have been collected regarding the performance of the trial traffic control devices. A detailed analysis of the data. including the results of an opinion survey. is provided in the attached report, titled "Traffic Calming Pilot Project - Final Report. Estudillo Estates Neighborhood". The report includes sections that describe the development of the pilot protect. the devices installed, changes in volume and speeds, effects on emergency access. public opinion. and staff s recommendations. BACKGROUND As a result of petitions submitted from the Estudillo Estates neighborhood, Citv Council approved a pilot program of neighborhood traffic controls in September, 1995. Three months later, speed humps and traffic circles were installed on Joaquin, Juana, Dolores and Maud Avenues. A temporary traffic circle using cones were installed at the intersection of Estudillo and Morgan Avenues. Within three days, the circle had been utterly destroyed by traffic and was removed. In addition, residents on the comer of Estudillo and Morgan complained that a circle would deflect traffic towards their homes. Observations by staff confirmed this could be a problem, and revealed that a circle could potentially cause rear end and left turn accidents. In January, 1996, a hump was installed on Sybil Avenue. In May, 1996, an opinion survey was conducted by mail to allow residents to express their thoughts on the traffic controls. Of the 339 post cards we sent out. 195 were returned for a response rate of 58%. 119 (or 61%) of the 195 respondents lived within 150 feet of a 22
