Nlslctr(y 1 CONSENT CALENDAR DATE: July 13, 1993 SUBJECT: ALTA MADERA ROAD - ESTABLISHING A PRIMA FACIE SPEED LIMIT Resolution No. 93-95 DEPARTMENT: Community Development BACKGROUND The Traffic Engineering Section received a request from the Sheriff's Department to conduct an Engineering and Traffic Survey to establish the prima facie speed limit on Alta Madera Road. The street is currently posted with 35 miles per hour speed limit signs at each end, however, the speed limit Is not justified by a traffic study. The California Vehicle Code requires that the study be performed every five years where enforcement Involves the use of radar or another electronic device which measures the speed of moving vehicles. The 85 percentile speed, the speed at or below which 85 percent of motorists travel, was, determined to be 40 miles per hour. The speed limit is normally established at the 85 percentile speed. However, the California Vehicle Code allows a 5 mile per hour reduction of the 85 percentile speed based on previous accident history, or highway, traffic, and roadside conditions not readily apparent to the driver. There have been no reported accidents on this street during the past two years. However, based on the existing curvature of the roadway, the proximity of Almendra City Park, the location of a recreation/swimming pool facility, and a pedestrian paseo, it Is recommended that the 85 percentile speed be reduced by 5 miles per hour. Based on the Engineering and Traffic Study, staff recommends a 35 miles per hour speed limit on Alta Madera Road between Avenida Navarre and Avenida Velarte. This speed limit is also compatible with other roadways in the area. RECOMMENDATION That the City Council adopt Resolution No. 93.95 , establishing a Prima Facie Speed Limit of 35 miles per hour on Alta Madera Road between Avenida Navarre and Avenida Velarte.

The street is presently posted with a 35 mph sign without an engineering and. traffic survey justification. RECOMMENDATION Based on the result of the Engineering and Traffic Survey, the recommended prima facie speed limit on Alta Madera Road between Avenida Navarre and Avenida Velarte Is 35.mph. EXISTING CONDITION Alta Madera Road is a residential collector road with a 40 ft. width. The street has one travel lane In each direction and on -street parking is allowed on both sides of Alta Madera Road. The street has an existing sidewalk, curb and gutter on both sides. The alignment of Alta Madera Road has horizontal curves and several local streets connect as'T' or4-way intersection. Also, the roadway Is within a residential area and adjacent to Almendra City Park, Valencia South Valley Homeowners recreation/pool area and paseo. The review of the accident history within the 24 month period from. January 1, 1991 to December 31, 1992 on Alta Madera Road, from Avenida Navarre to Avenida Velarte, showed no reported Intersection and mid -block accidents. DISCUSSION Alta Madera Road was divided Into two segments for.the purpose of the study, segment #1 from Avenida Navarre to Maravilia Court and segment #2 from Maravilla Court to Avenida Velarte. Data was collected on April 6 and 8, 1993, respectively. The results of the traffic survey were as follows: Anthony J. Nisich, City Engineer June 29; 1993 Page 2 SEGMENT NO. 1 NO. 2 LIMITS 85TH PERCENTILE 10 MPH PACE (% OF VEH.) Ave. Navarre to 40 mph 29.38 mph Maravilla Ct. (76.4%) Maravilla Ct. to 40 mph 3241 mph Ave. Velarte (82.9%) Field observations indicated that the existing horizontal curve limits the sight distance coming out of some of the side streets. Also, pedestrians were observed crossing Alta Madera Road to access the park, recreation/pool area and the paseo. Based on the data collected, the existing conditions and observations mentioned above, staff recommends to reduce the 85th percentile speed by 5 mph and establish a prima facie speed limit of 35 mph on Alta Madera, between Avenida Navarre and Avenida Velarte. This speed zone is compatible with the other roadways in the surrounding area (see attached vicinity map.)
