ENG TITLE: ESTABLISH A PRIMA FACIE SPEED LIMIT UPON TAMARACK AVENUE FROM HARWICH DRIVE TO COLLEGE BOULEVARD CITY ATTY & CITY MGR- RECOMMENDED ACTION: Introduce Ordinance No. NS-706 35 mile per hour speed limit from Harwich Drive to its intersection with College Boulevard. to establish upon Tamarack Avenue a prima facie ITEM EXPLANATION: Tamarack Avenue serves as a residential collector road in the Calavera Hills area. With the current single-family home development under construction, Tamarack Avenue was extended from Harwich Drive easterly to College Boulevard. The portion of Tamarack Avenue from Carlsbad Village Drive to Harwich Drive has a previously established speed limit of 35 miles per hour. The subject portion of Tamarack Avenue follows a curvilinear alignment and has centerline grades up to 12%. The road has one traffic lane in each direction separated by double yellow centerline striping with a bicycle lane striped on both sides of the road. Tamarack Avenue has a curb-to-curb width of 40 feet with sidewalks and street lights constructed on each side. A recent traffic count on Tamarack Avenue found a 24-hour two-way average daily traffic (ADT) volume of 492 vehicles near Harwich Drive and 1,144 vehicles near Colleq,e Boulevard. A speed survey conducted on the subject portion of Tamarack Avenue found the 85 percentile speed, commonly called the critical speed, to be 35 miles per hour. The critical speed is the speed at which 85 percent of the vehicles are traveling at or below. Sections 22357 and 22358 of the California Vehicle Code authorize local authorities to establish a prima facie speed limit on the basis of the results of an Engineering and Traffic Survey. The Engineering and Traffic Survey considers such factors as the number of collisions that have occurred on the road segment, roadway features, adjacent land uses, driveway locations, traffic volumes, pedestrian volumes, critical speed, horizontal and vertical alignment, stopping sight distance, and conditions that may not be readily apparent to the driver. At their meeting on May 3, 2004, the Traffic Safety Commission considered the results of the Engineering and Traffic Survey to establish a prima facie speed limit upon Tamarack Avenue. The Commission recommended by a 5-0 vote that a 35 mile per hour prima facie speed limit be established upon Tamarack Avenue from Harwich Drive to its intersection with College Boulevard, thereby extending the existing 35 mile per hour speed zone on Tamarack Avenue. The current version of the Engineering and Traffic Survey is on file in the office of the City Traffic Engineer. FISCAL IMPACT: Installing two speed limit signs upon Tamarack Avenue will cost about $250. EXHIBITS: 1. Location Map. 2.
