Green Canyon signal goes live after eight years

After eight years in the process, the traffic light on South Mission and Green Canyon went active on Tuesday, Nov. 22. Community requests to have a signal at Green Canyon stemmed from multiple accidents and deaths at the intersection.

The proposed signal at Green Canyon and South Mission Road was first slated to be discussed during a Department of Public Works (DPW) Traffic Advisory Committee (TAC) in December 2014 but was pulled off that agenda to allow the Fallbrook Community Planning Group to provide input. Although the intersection met signal warrants in 2014, the planning group was concerned about potential adverse impacts to the traffic flow and recommended that the DPW consider potential alternatives to signalization.

A multi-day October 2014 traffic survey revealed a two-way average daily volume of 10,570 northbound vehicles on South Mission Road south of Green Canyon Road; 10,230 southbound vehicles on South Mission Road north of Green Canyon Road, and 1,160 westbound vehicles on Green Canyon Road east of South Mission Road.

The speed limit on South Mission Road at Green Canyon Road was 50 mph. South Mission Road was classified as a Boulevard in the Mobility Element network of the county's general plan.

Two years later, on Oct. 28, 2016, the county's TAC recommended that the intersection of South Mission Road and Green Canyon Road be placed on the county's Traffic Signal Priority List. Caltrans passed the project with eight members present and voting in support of the signal, which sent the proposal to the county board of supervisors for a final vote.

On Jan. 11, 2017, the supervisors added the Green Canyon/South Mission Road project to the list of intersections where traffic signals would be installed when funding and design issues allowed.

This added the signal to the Traffic Signal Priority List, which is based on priority points rather than the length of time on the list determining the next intersection to be signalized when funding becomes available.

Priority points are based on vehicular volume, pedestrian volume, flow interruption reduction, hazard reduction, coordinated movement potential, and special conditions. The county's DPW reviews intersections on the priority list annually to revise priority points. Design readiness issues may allow a lower-ranked intersection to be signalized first, as can grant funding for a specific intersection.

During that Jan. 11, 2017 Board of Supervisors meeting, Jeannine Huffman spoke about losing her father in an accident at that intersection.

Village News reported that on the morning of Dec. 15, 2016, Bonsall resident Patrick Germon was killed when he attempted to make a left turn from Green Canyon Road onto South Mission Road and was hit by a vehicle traveling along South Mission Road.

"We ask that you pass it for Fallbrook," said Huffman. "We've lost too many lives."

Germon and his wife, Elizabeth, had been married for 45 years. "This is something not only for us, but anybody who goes there," Elizabeth Germon said. "There are quite a few people in Fallbrook that are very concerned about this."

Huffman informed the supervisors that two additional accidents at that intersection occurred after her father's death.

On Aug. 25, 2020, the Board of Supervisors approved San Diego County's fiscal year 2020-2021 budget which included funding for traffic signals at the intersections of East Mission Road and Santa Margarita Drive, South Mission Road and Green Canyon Road, and Old Highway 395 and Rainbow Glen Road.

The Old Hwy. 395 and Rainbow Glen Road signal, as of printing, was supposed to go live on Thursday, Dec. 1, 2022.

The traffic signal at Green Canyon has caused many traffic backups, sometimes from the signal all the way down to River Village and Hwy 76.

The next story will include what DPW is doing to calibrate or set the timing on the signals to decrease traffic on South Mission.
