HomeMy WebLinkAboutStaff Report to the Traffic Safety C. on February 12, 20142 NATIONAL CITY TRAFFIC SAFETY COMMITTEE AGENDA REPORT FOR FEBRUARY 12, 2014 I ITEM NO. 2014-02 I ITEM TITLE: REQUEST FOR INSTALLATION OF RAISED PAVEMENT MARKERS FOR TRAFFIC CALMING ON DIVISION STREET BETWEEN `aD" AVENUE AND IiiiGHLAND AVENUE (BY C. PELAYO1 PREPARED BY: Stephen Manganiello, City Engineer DISCUSSION: Ms. Claudia Pelayo, resident of 710 E. Division Street, has requested raised pavement makers for traffic calming on Division Street between "D" Avenue and Highland Avenue to reduce the potential for speeding and traffic collisions, Ms. Pelayo's vehicle, which was parked in front of her home on Division Street, was damaged several times over the past year due to drivers losing control of their vehicles and colliding into Ms. Pelayo's vehicle. She has a young child and is concerned about safety. This segment of Division Street between "D" Avenue and Highland Avenue is a divided roadway with a significant change in elevation between eastbound and westbound traffic. Westbound Division Street, which is at a lower elevation, is located within the City of San Diego, while eastbound Division Street is located within the City of National City. This report focuses on eastbound Division Street. Eastbound Division Street between "D" Avenue and Highland Avenue has one 12-foot wide travel lane adjacent to an 8-foot wide striped parking lane. The striped parking lane with reflectors and raised pavement markers was installed in 2011 as a traffic calming measure. Drivers traveling eastbound will experience a series of vertical curves prior to arriving at the traffic signal at Highland Avenue. A "Signal Ahead" warning sign with yellow flashing warning beacon was installed in 2011 to warn drivers of the upcoming traffic signal. The posted speed limit is 30 mph. Comparison of radar speed survey data from 2007 to 2011 indicates a reduction in 85th percentile speeds (speed at or below which 85% of vehicles surveyed were traveiing) of 7 mph (from 36 mph to 29 mph). Review of traffic coiiision history indicates an average of one to two injury and/or property damage collisions per year. On November 21, 2013, staff from the Engineering Department, Police Department and City Manager's Office hosted a Neighborhood Workshop to discuss traffic conditions and residents' concerns on this segment of Division Street. A copy of the letter inviting residents and presentation are attached to this report. After listening to testimony from residents, staff presented several options for traffic calming: 1) Install a series of raised pavement markers at set intervals across the roadway; 2) Install a series of raised concrete buffers in the parking areas; 3) Install a radar speed feedback sign with flashing beacons. Options 1 and 3 were supported by the vast majority of residents. Since funding is not currently available for Option 3, staff recommends implementation of Option 1. Care will be taken as to not place the raised pavement markers in proximity to residents' windows to minimize noise impacts. STAFF RECOMMENDATION: Install a series of raised pavement markers at set intervals across eastbound Division Street between "D" Avenue and Highland Avenue for traffic calming. EXHIBITS: 1.
