I I, CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT ._) COMMISSION MEETING OF: November 2, 1992 LOCATION: Park Drive -Hillside Drive to Marina Drive ITEM NO. 6A INITIATED BY: Sgt. Metcalf, Carlsbad Police Department REQUESTED ACTION: Evaluate the subject segment of Park Drive and conduct an Engineering and Traffic Survey to establish a prima facie speed limit. BACKGROUND: DATA: The subject segment of Park Drive is currently posted as a 25 mile per hour speed zone. Due to the high critical speeds in this road segment, the 25 mile per hour speed zone may not be justified. Park Drive is a two lane, local road 2.55 miles in length between Westhaven Drive and Via Marta. At a location approximately 150 feet south of Hillside Drive, Park Drive has an Average Daily Traffic (ADT) volume of 1,420 vehicles based upon a recent traffic count. The roadway follows a curvilinear alignment and is characterized by varying sections of the roadway having adjacent single-family residential units, apartments, condominiums or open space. Numerous streets intersect the road and many driveways are located on Park Drive. Curb and gutter, sidewalks and street lights are located on some segments of Park Drive. The roadway has not been constructed to its ultimate local street standard in all locations. At the present time, two speed zones exist on Park Drive as indicated on Exhibit 1 and these zones have been established in the Carlsbad Municipal Code. Regulatory speed limit signs are posted on Park Drive also as shown on Exhibit 1. The 25 mile per hour speed zone between Westhaven Drive and Marina Drive was established years ago after a study indicated that this segment meets the residence district definition of the California Vehicle Code for the roadway between those limits. However, for most of the 0.50 mile segment of Park Drive between Hillside Drive and Marina Drive the adjacent land use is vacant parcels or condominiums. Two speed surveys were recently conducted on Park Drive. The survey conducted south of Hillside Drive and the survey south of Cove Drive indicate critical speeds of 40 miles per hour and 39 miles per hour, respectively. The pace speed south of Hillside Drive was 30 to 40 miles per hour with 75 % of the vehicles in the pace. South of Cove Drive the pace speed was 31 to 41 miles per hour with 85% of the vehicles in the pace. CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: November 2, 1992 ( continued) ITEM No. 6A There have been four traffic collisions reported on the road segment of Park Drive between Hillside Drive and Marina Drive in the last five years. Two of the four collisions had been exceeding the safe speed as the primary collision factor as indicated on Figure 2. RECOMMENDATION: Based upon the results of the engineering and traffic survey, the Traffic Safety Coordinating Committee recommends that a 35 mile per hour prima facie speed limit be established on Park Drive from Hillside Drive to its intersection with Marina Drive. The Traffic Safety Coordinating Committee further recommends that the other speed zones remain as currently posted. NECESSARY CITY COUNCIL ACTION: An ordinance is required to be adopted by the City Council to establish the prima facie speed limit as recommended. AVE.
