State Route 227 and Los Ranchos Road Intersection Operational Improvements Project
The County of San Luis Obispo Department of Public Works, San Luis Obispo Council of Governments (SLOCOG), and Caltrans are in the preliminary engineering phase of a project to improve operations at the State Route 227 and Los Ranchos Road intersection. To determine the best solution at this intersection, the study team commissioned a detailed traffic analysis of the State Route 227 corridor from Aero Drive to Price Canyon Road, known as the 2021 State Route 227 Corridor Traffic Study.
October 12, 2021 - Virtual Public Meeting on DRAFT 2021 Corridor Traffic Study.
September 29, 2021 – Draft 2021 Corridor Traffic Study completed
May-June 2021 – Consultant continues efforts on traffic analysis and County is on schedule to present the findings to the community this fall/winter. Conducted public outreach ahead of the DRAFT 2021 State Route 227 Corridor Traffic Study via six focus groups, which included stakeholders that work in emergency response, air quality, agriculture, business, tourism, biking, Los Ranchos Elementary, and affected neighborhoods.
July 14, 2020 - The topographic survey, geotechnical explorations, and traffic forecasting is complete. Work continues to analyze each corridor alternatives under current and future traffic volumes. The County hopes to present the findings of the traffic analysis to the community this fall/winter 2021.
November 19, 2019 - The San Obispo County Board of Supervisors approved Phase 1 of a professional consultant services contract with Rick Engineering Company.
March 20, 2019 - The first townhall meeting was held at Los Ranchos Elementary School. Representatives from the County, Caltrans, and San Luis Obispo Council of Governments (SLOCOG) were present to inform the public about the proposed project and listen to comments and concerns.
The Project is funded through federal Congestion Mitigation Air Quality (CMAQ) program funds and State Highway Account (SHA) funds programmed through the San Luis Obispo Council of Governments (SLOCOG).
2021 Corridor Traffic Study & Public Meeting
As part of the preliminary engineering phase of this project, the study team commissioned a detailed traffic analysis of the State Route 227 corridor from Aero Drive to Price Canyon Road to assess the congestion and safety benefits of various project alternatives at high priority intersections, including: Farmhouse Lane, Buckley Road, Crestmont Drive, Los Ranchos Road, and Biddle Ranch Road.

In 2015, the San Luis Obispo Council of Governments (SLOCOG) initiated a corridor study to develop solutions to growing congestion on State Route 227 between Tank Farm Road and Price Canyon Road. The study included analysis of the following two possible solutions for the corridor:
1. Widening of State Route 227 to 2-lanes in each direction and upgrading the signals at various intersections
2. Constructing a series of roundabouts at key intersections
SLOCOG held three workshops during the development of the study to gain input from the public regarding the two alternatives. To improve operations by relieving existing and future congestion, the study recommended constructing a series of roundabouts, starting with Los Ranchos Road as a priority project, followed by Buckley Road.
The SLOCOG Board approved the operations study and technical appendices in January of 2017.
November 19, 2015 - SLOCOG Public Workshop #1
May 24, 2016 - SLOCOG Public Workshop #2
September 15, 2016 - SLOCOG Public Workshop #3
January 17,2017 – SLOCOG’s State Route 227 Operations Study was adopted. For details, see the Project Background section below.

Frequently Asked Questions
Roundabouts are proven to reduce injury and fatal crashes compared to traditional intersections. Roundabouts are effective at slowing down traffic so that when crashes do occur, they usually occur at low speeds and are unlikely to cause injury or major damage. Roundabouts are also able to prevent head-on and T-bone types of crashes.
- If you have not entered the roundabout, pull over and allow emergency vehicles to pass.
- If you have entered the roundabout, proceed to your desired exit, exit the roundabout, and the pull over to allow the emergency vehicle to pass.
- Avoid stopping in the roundabout since this could prevent emergency vehicles from passing and other vehicles from exiting.
Pedestrians should follow a few rules when crossing any roundabout:
- Cross the road to the median, using it as a refuge area to wait for a safe gap.
- Always look for vehicles and make sure that all motorists can see you. Never assume that a motorist can see you or intends to stop for you.
Stay on the sidewalk. Never walk in the roundabout or cross to the circular island.
There are no bicycle lanes within a roundabout. When the bike lane ends, bicycles have two options when approaching a roundabout depending on their comfort level:
- Bicyclists may merge with vehicular traffic and travel around the roundabout following all the same rules as a vehicle.
- Bicyclists may exit using the shared-use paths and crosswalks, following the same rules as pedestrians.
