TO: HONORABLE MAYOR AND MEMBERS OF CITY COUNCIL
FROM: DIRECTOR OF PUBLIC WORKS
DATE: NOVEMBER 16, 2004
SUBJECT: LONGHILL DRIVE AND FLAMING ARROW DRIVE - MULTIWAY STOP CONTROLS
STAFF COORDINATOR: Ron Dragoo, Senior Engineer
The Soleado Elementary School PTA and school staff has requested additional traffic controls in the vicinity of the subject school to address safety issues. Staff met with school representatives and PTA members and discussed several traffic circulation, parking, pick-up and drop-off operations and educational materials. Many of the suggestions involved modifications on school property, prompting the Principal to take them under consideration. Also included was the possibility that multi-way stop controls may be warranted at the intersection of Longhill Drive and Flaming Arrow Drive. Staff evaluated this location to determine if additional traffic controls were appropriate based on general traffic engineering guidelines and practice.
Longhill Drive and Flaming Arrow Drive are single-family residential streets that border Soleado Elementary School with 25 mph residential prima facie speed limits. Flaming Arrow Drive forms the stem of a T-intersection with Longhill Drive, and has a posted "STOP" sign and pavement marking. Flaming Arrow Drive is thirty-six feet wide and there is a yellow school crosswalk on Flaming Arrow Drive. Longhill Drive is thirty-six feet wide with skip yellow centerline. It is not stop controlled at the subject intersection. The east leg of the intersection, on Longhill Drive, fronts Soleado Elementary School while the west leg connects to Silver Arrow Drive.
Previous measurements of traffic at the intersections indicate a peak of 273 vehicles per hour with a prevailing (85th percentile) speed of 34 mph. A review of the accident history at this location disclosed no reported intersection-type accidents during the three-year period ending July 2004.
Peak hour observations revealed that traffic volumes would fall below Federal and State guidelines for the installation of multi-way stop controls. For a prevailing speed of 34 mph, the minimum stopping sight distance per AASHTO (American Association of State Highway and Transportation Officials) standards is approximately 250 feet. Measurements taken on Flaming Arrow Drive looking south indicated that there is 205 feet of visibility. The remaining intersection views have adequate visibility for prevailing conditions. As shown in the City of Rancho Palos Verdes all-way stop control warrants, the limited visibility justifies consideration of multi-way stop control installation.
This information was presented to the Traffic Committee at their regularly scheduled October 25, 2004 meeting. The Committee voted unanimously, concurring with staff’s recommendation, to install a multi-stop intersection at Flaming Arrow Drive and Longhill Drive.
Based on this information, installation of multi-way stop controls at this location is appropriate. To provide adequate advance notification of the stop signs on Longhill Drive, Stop Ahead warning signs and pavement markings should also be installed.
As a courtesy to the neighborhood a notice of this proposal to install stop signs was posted on November 5, 2004 informing them of this meeting.
Adopting Staff’s recommendations will establish three way stop controls at the intersection of Longhill Drive and Flaming Arrow Drive, resulting in improved visibility and traffic safety.
The recommended action results in no negative fiscal impact. All costs related to the installation of three-way stop controls will be paid for from the Traffic Maintenance fund.
Respectfully Submitted, Reviewed,
