Rancho Santa Fe Roundabouts

Proposed Project Overview

The Rancho Santa Fe Roundabouts project aims to enhance traffic operations, safety, and connectivity in the Rancho Santa Fe area of San Diego County. This capital improvement initiative encompasses the construction of strategically placed roundabouts, providing continuous traffic flow, speed control, and improved accessibility for pedestrians, equestrians, and cyclists. The project also includes stormwater drainage enhancements and the integration of Greenstreets infrastructure, local landscape and aesthetic elements, all while preserving the area’s historic character. With a focus on minimizing impacts to property owners and adhering to current engineering standards, the project seeks to optimize traffic operations and enhance the overall transportation experience. Through community outreach and stakeholder engagement, the project team is working towards achieving a harmonious balance between functionality, safety, and the unique charm of historic Rancho Santa Fe and surrounding communities.

April 2026 Project Update:
 
Eastern Intersection Update: Paseo Delicias / Del Dios Road at El Camino del Norte

As part of the Final Plan Check, we coordinated with the Rancho Santa Fe Fire District to conduct an additional design review of the roundabout and roadway layout at this intersection. This review focused on ensuring the intersection meets fire district requirements for emergency vehicle access and evacuation routing.

Key Design Changes

Following the Fire District's review, two primary changes were made to maximize emergency equipment access:

• All travel lanes have been widened to a minimum of 20 feet.
• The full roadway width has been cleared of all landscaping and obstructions to ensure it is fully traversable during an emergency.

Updated Roadway Layout

The refined design includes:

• A separated emergency shoulder located just outside the travel lane
• All landscaping relocated to outside of the roadway
• Rolled/mountable curbs used exclusively within the roadway

Pedestrian Connectivity

Pedestrian crossings are located on each leg of the intersection with connections to the existing trail network. Each leg of the intersection will have enhanced crosswalks with visibility signage, lighting and push-button flashing yellow lights to alert drivers. The western crosswalk is designed to facilitate equestrian crossings, complete with an extended 10’ trail width and an equestrian push button signal that provides dedicated connectivity to the adjacent equestrian trail as shown in the County Trail Master Plan.  

Roundabout Center Feature

While plantings in the center of the roundabout have been removed to meet emergency access requirements, the Historic Rancho Santa Fe sign will be installed in the center island. The sign will serve as a landmark welcoming drivers into the residential area and signaling reduced speeds ahead.

Project Status:

All three intersections are fully funded for engineering technical studies and design phase of project development.

In 2024 the County Board of Supervisors approved the programming of TransNet funding in fiscal year 2027/2028 for phased construction, and DPW is moving forward to fully construct the eastern roundabout at Paseo Delicias/Del Dios Rd and El Camino del Norte.

Future stages of the project (central roundabout at El Montevideo and westernmost roundabout at Via de la Valle) are currently unfunded for construction.  An additional $15M will be needed to construct the central and west intersection roundabouts, and staff is continuing pursue state, regional, and federal funding opportunities.
