Santa Rosa Downtown Station Area Specific Plan (DSASP) Update

The City of Santa Rosa has entered into a Development Agreement with Museum on the Square, LLC for the adaptive reuse or redevelopment of the City Hall Campus. This project involves approximately 5.96 acres of city-owned property located at 90 Santa Rosa Avenue, 631 1st Street, 655 1st Street, and a portion of 100 Santa Rosa Avenue. While no site-specific development proposal is currently in place, the agreement is designed to be consistent with the Downtown Station Area Specific Plan. For environmental analysis purposes, the project conservatively assumes the potential demolition of 13 existing buildings totaling approximately 97,811 square feet along with associated site improvements. The project is subject to the California Environmental Quality Act and the Public Resources Code, with the City of Santa Rosa serving as the lead agency. A Supplemental Environmental Impact Report is being developed to evaluate potential impacts on historical resources and to determine if additional mitigation measures are required. This process includes an Initial Study and a Real Property Exchange Agreement, both of which were processed in August 2026. The overall scope of work is governed by the goals, policies, and standards established in the Downtown Station Area Specific Plan.
