BACKGROUND: This request was initiated by the Police Department Traffic Division based upon traffic operations in the vicinity of La Costa Canyon High School. The Police Department has observed the illegal use of the existing parking/bike lane area of eastbound Camino de los Coches as a vehicle through lane between Calle Timiteo and Maverick Way during the morning hours prior to the start of the high school. Based on these observations and considering the high volume of vehicular traffic entering the La Costa Canyon High School in the morning, the Police Department has requested that the Engineering Department Transportation Division investigate the possibility of re-striping this portion of Camino de los Coches, increasing the number of eastbound through lanes from one to two. DATA: Camino de los Coches is classified as a secondary arterial and has a curb to curb width of 64 feet. This roadway is fully improved with curb/gutter, sidewalks and streetlights on both sides of the road. There are two travel lanes in each direction from Rancho Santa Fe Road to Calle Timiteo. East of Calle Timiteo, eastbound Camino de los Coches transitions from two travel lanes to a single travel lane with a parking lane and bicycle lane provided. The eastbound parking lane and bicycle lane ends approximately 300' west of Maverick Way in order to accommodate a RIGHT TURN ONLY lane that serves the high school. In the westbound direction, there is a single travel lane, a parking lane and a bicycle lane from Maverick Way to approximately 335' east of Calle Timiteo. From approximately 335' east of Calle Timiteo to Rancho Santa Fe Road, there are two westbound travel lanes. Exhibit 1 shows the project location. Traffic control on this portion of Camino de los Coches is provided by traffic signals at Rancho Santa Fe Road, Calle Timiteo, Calle Acervo, and Maverick Way. The average daily traffic volume on Camino de los Coches east of Rancho Santa Fe Road is 9,790 as measured on May 9, 2006. Camino de los Coches serves as the only access to Stagecoach Park and as the primary access to La Costa Canyon High School. The normal school hours for La Costa Canyon High School are from 7:45 a.m. to 2:30 p.m. ( CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: December 3, 2007 ( continued) ITEMNO. 6B The mid-block collision rate, as measured from September 1, 2005 to August 31, 2007, is 1.68 accidents per million vehicle miles. This compares favorably to the statewide averages of 2.03 and 2.14 accidents per million vehicle miles for 2 lane roadways and 4 lane divided roadways, respectively. On a typical school morning, vehicles from the west utilize the parking/bike lane area of eastbound Camino de los Caches to access La Costa Canyon High School at Maverick Way. The eastbound queue in the parking/bike lane area of Camino de los Caches resulting from the right turning vehicles into the school driveway has been observed to extend to Calle Timiteo and beyond. As typical with most schools, the majority of the congestion is confined to a relatively short period of time, with the peak being observed to be approximately 7:15 a.m. to 7:45 a.m. Vehicles from the east use the westbound left turn lane on Camino de las Caches at the traffic signal to enter the school grounds. A number of students also access the school from Stagecoach Park. The majority of these students turn right into Stagecoach Park from westbound Camino de los Caches and either use the parking lot to make a u-turn and access the school from the southbound approach of the Stagecoach Park driveway, or they park in the Stagecoach Park parking lot and walk to school. The proposed re-striping would encompass approximately 1400 linear feet of roadway and require the removal of existing striping, new striping, signing modifications and reconfiguration of the video detection zones on eastbound Camino de los Coches at Calle Acervo. The proposed re-striping would eliminate on-street parking on the south side of Camino de los Coches between Calle Timiteo and Maverick Way. Currently, there is approximately 565 feet of curb available for parking on the south side of Camino de los Caches. Assuming an average parallel parking space of 25 feet, this is equivalent to approximately 22 parked vehicles. The north side of Camino de los Coches would be unaffected by the proposed re-striping and the existing on-street parking would remain. There is approximately 915 feet of curb available for parking on the north side of Camino de los Caches between Calle Timiteo and Maverick Way, which can accommodate approximately 36 parking spaces. Exhibit 2 shows the existing striping on Camino de los Coches as well as the proposed striping changes. The on-street parking demand on the subject segment of Camino de los Caches is relatively light, especially on the south side. The only parking generators in the vicinity, Stagecoach Park and La Costa Canyon High School, both have off-street parking. Based on staff observations, the parking area along the south side of Camino de los Caches is minimally utilized. However, special events at Stagecoach Park do result in on-street parking to be fully utilized. The City of Carlsbad has an annual pavement management program that either provides an asphalt overlay or slurry seal on designated streets. Camino de los Coches is not scheduled to be overlayed or slurry sealed for approximately four years. ( ( CITY OF CARLSBAD TRAFFIC SAFETY COMMISSION STAFF REPORT COMMISSION MEETING OF: December 3, 2007 ( continued) RECOMMENDATION: ITEMNO. 6B Based on these findings, the Traffic Safety Coordinationg Committee recommends that eastbound Camino de los Coches be re-striped between Calle Timiteo and Maverick Way to increase the number of eastbound travel lanes from one to two. This proposed striping will result in two eastbound travel lanes on Camino de los Coches, from Rancho Santa Fe Road to Maverick Way, with the new lane terminating at the existing RIGHT TURN ONLY lane on eastbound Camino de los Coches at Maverick Way. NECESSARY CITY COUNCIL ACTION: City Council approval of establishing the no parking zone on the south side of Camino de los Coches that will result by re-striping the road will be required by adoption of an ordinance.
