BACKGROUND: DATA: Camino Junipero is a four-lane road located in the southeast portion of Carlsbad which previously terminated at Avenida Amapola. The roadway originally opened to traffic in early 2005. Due to development, the road has recently been extended approximately a quarter of a mile to the south. The roadway now terminates at Paseo Encino (see Exhibit 1). The ordinance establishing the current 45 mile per hour speed zone from Rancho Santa Fe Road to Avenida Amapola was adopted in 2006. The ordinance must be revised to extend the speed zone to the roadway's new terminus at Paseo Encino. Camino Junipero is classified as a local/neighborhood street in the Mobility Element in the General Plan. Its cross-section has been modified from the standard cross-section for a major arterial roadway to one having a curb-to-curb width of 64 feet. The road has two traffic lanes in each direction extending to the intersection of Avenida Maravilla where the southbound lane is then reduced to one lane, several hundred feet east of Avenida Maravilla. South of Avenida Amapola there is one lane in each direction. A bicycle lane is striped on each side of the road. Immediately east of Rancho Santa Fe Road, a raised median has been constructed on Camino Junipero for a distance of 150 feet where it terminates and a striped double double yellow median has been installed on the remaining length of Camino Junipero. A traffic signal controls Camino Junipero at its intersection with Rancho Santa Fe Road. Five streets intersect Camino Junipero east of Rancho Santa Fe Road and all are controlled by a stop sign when entering Camino Junipero. Four of the intersecting streets, Avenida Maravilla, Avenida Amapola, Camino Bello, and Paseo Encino are configured as T-intersections. The only four-leg intersection southerly of Rancho Santa Fe Road on Camino Junipero has side streets with two different names. The westerly street is named Camino Cereza and the easterly street is named Corte Romero. Camino Junipero terminates into a T-intersection at Paseo Encino. A trail easement and a San Diego Gas and Electric easement intersect Camino Junipero. Centerline roadway grades on Camino Junipero vary from 1.2% to 6.0%. Concrete sidewalks, curb and gutter, and street lights have been constructed to city standards on each side of the roadway. Parking is prohibited on both sides of Camino Junipero. Staff reviewed the Police Department collision reports for the two-year period from April 1, 2014 through March 31, 2016. There have been no reported collisions. Staff conducted a speed survey on Camino Junipero on April 18, 2016 to obtain data to calculate the critical speed of vehicles. The critical speed, commonly called the 85th percentile speed, is the free flowing speed at which 85 percent of the vehicles are traveling at or below. A sample of 100 vehicles was measured to determine the critical speed. The critical speed is an important factor required to be considered in the evaluation of the appropriate prim a facie speed to post upon a roadway. Staff completed the Engineering and Traffic Survey (attached) for Camino Junipero from Rancho Santa Fe Road to its terminus at Paseo Encino. Results of the speed survey, contained within the Engineering and Traffic Survey that was conducted on Camino Junipero, are summarized in Table A. The pace speed is the 10 mile per hour range of speeds that contain the highest number of observed vehicles. Generally, the critical speed is located within the pace speed. 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. There are not conditions existing along this section of roadway that are not readily apparent to the driver or support a lower speed limit. RECOMMENDATION: Based upon the results of the Engineering and Traffic Survey, the Traffic Safety Coordinating Committee recommends establishing a 45 mile per hour prima facie speed limit upon Camino Junipero from Rancho Santa Fe Road to its terminus at Paseo Encino. NECESSARY CITY COUNCIL ACTION: An ordinance will be required to be adopted by the City Council to establish the 45 mile per hour prima facie speed limit upon Camino Junipero, as recommended.

Traffic Engineer's Recommendation (Explanation): This speed zone satisfies the conditions of Section 627 of the California Vehicle Code and has been prepared and evaluated in accordance with the California Manual on Uniform Traffic Control Devices, effective November 7, 2014, with respect to design and prevailing speeds, accident records, pedestrian and bicyclist safety, intersection and driveway spacing, and roadside and traffic conditions not readily apparent to the driver. A speed limit posting of 45 MPH is found to be annrooriate and iustified. I.
