Pacifica planning panel reapproves Caltrans signs and wireless detectors for State Route 1 after permit lapse

The Pacifica Planning Commission voted to reapprove a coastal development permit that lets the California Department of Transportation (Caltrans) install wireless vehicle detection modules and a variable message sign (VMS) at two locations on State Route 1 in Pacifica.

The commission action on the State Route 1 traffic operations improvements project adopted Caltrans’ May 2021 Initial Study and Negative Declaration for the corridor and approved Coastal Development Permit CDP-468-24, with a motion by Commissioner Ferguson and a second by Commissioner Redfield; the motion passed by recorded tally (motion summary in record).

Caltrans consultant Jacob Garcia presented the application and staff packet, describing it as the same project the commission approved in 2022 that now requires reapproval because the original permit expired before construction began. The reapproved work within Pacifica includes: installation of a small wireless detection module mounted about 25 feet high at the intersection of State Route 1 and Reina Del Mar Avenue (Location 9-1); and a 12-foot-by-5-foot variable message sign (VMS) mounted on two wooden poles, roughly 200 feet of power trenching, a controller and service cabinet on concrete pads, and about 100 feet of guardrail on the northbound shoulder (Location 9-2).

The project’s stated purpose is to improve incident detection and traveler information for emergencies, evacuations and traffic incidents, and to feed recurrent and nonrecurrent congestion data to Caltrans’ Traffic Management Center in Oakland. Nandani Shraddar, Caltrans project manager, told commissioners the systems “work in conjunction with the [traffic management center] and are able to notify that there is congestion,” and that the VMS and detection modules are intended to provide redundant, on‑road information that can reach drivers who are not running navigation apps.

Commissioners and members of the public questioned whether existing Caltrans phone apps and online services (QuickMap) could substitute for permanent roadside signs. Minh Li, a Caltrans technical specialist, agreed those tools provide information but said the road‑side VMS provides a “supplement” for drivers who do not have a navigation app running, and that permanent signs are more visible and useful than portable signs when incidents occur. Shraddar and other Caltrans staff also pointed to response-time advantages for emergency management and the difficulty of getting portable message signs into place quickly during incidents.

Some commissioners pressed Caltrans about siting. Vice Chair Berman and others reiterated an earlier commission request for a southbound sign that would warn Pacifica drivers before they enter the tunnels; Caltrans staff said separate southbound signs exist in other jurisdictions and that the siting for this set of locations was selected to give motorists time to take alternate routes. Commissioner Redfield asked why the earlier permit was allowed to expire; Caltrans staff said delays pushed actual construction into mid-2024 and they failed to request a time extension before expiration.

The commission discussed visual impact choices; Caltrans’ landscape planner Kimberly White said wooden poles were selected in part to reduce perceived visual contrast in the coastal context and had been part of prior Coastal Commission discussions. The staff report describes Caltrans as the CEQA lead agency; Caltrans filed a Notice of Determination on May 11, 2021, adopting the initial study and negative declaration for the broader SR‑1 corridor improvements.

After deliberation the commission found no new evidence requiring additional environmental review, adopted the Caltrans negative declaration for purposes of the city’s responsible‑agency review, and approved the coastal development permit and conditions included in the staff resolution. The staff report and exhibits describe the exact module dimensions (roughly 9 by 7.5 by 7 inches), VMS size (about 12 by 5 feet), guardrail and trenching lengths, and required foundations and pull boxes.

Caltrans representatives said Pacifica work should be completed within weeks once permits are granted and that the VMS will be lit only when needed. Commissioners asked staff to follow up on whether portable message signs seen in the corridor are Caltrans‑ or city‑owned and asked Caltrans to continue considering a southbound permanent sign for Pacifica.
