Santa Rosa is about to give two of its neighborhood corridors a serious glow-up. This spring, the city plans to pour millions into Hopper Avenue through Coffey Park and a roughly one-mile stretch of Calistoga Road in Rincon Valley. On the menu: fresh pavement, protected bike lanes, upgraded bus stops, and new water and sewer lines to replace aging infrastructure. The work will roll out in phases, so neighbors can count on lane shifts, temporary bus stop moves, and short detours as crews inch along the routes.
Community members and city officials are set to mark the occasion with a milestone ceremony on April 14 before the heavy equipment shows up, according to The Press Democrat. The outlet reports the two projects together are worth more than $17 million and are backed by a mix of state and local funding that covers both construction and utility upgrades.
Hopper Avenue: Coffey Park’s long-awaited rebuild
The Hopper Avenue overhaul is designed to undo fire and debris-removal damage and restore a key connection between Coffey Park and US-101. Earlier this year, the City Council signed off on a $4.7 million construction contract with Argonaut Constructors. As detailed by the City of Santa Rosa, the project will repave the stretch between the 101 south entrance and Coffey Lane and add landscaped medians, buffered bike lanes separated by bollards, new sidewalks, upgraded crosswalks, and a rapid-flashing beacon near Piner Creek. To keep disruptions in check, the work will be staged to avoid long closures, and the city is holding public meetings before construction kicks off.
Calistoga Road: a deeper rebuild in Rincon Valley
Over in Rincon Valley, the City Council approved a roughly $12.7 million contract to rebuild about 1.1 miles of Calistoga Road, running from Montecito Boulevard up to Highway 12, The Press Democrat reports. This one goes well beyond a basic repave. Crews will replace or upsize underground water and sewer mains, install buffered or protected bike lanes in key segments, bring curb ramps up to ADA standards, and upgrade bus stop infrastructure to improve safety for people walking, biking, and riding transit.
Schedule, technique and what to expect
City planning documents show work on Calistoga Road is scheduled to begin in May 2026 and wrap up around July 2027, with crews using pulverizing and asphalt-recycling methods to turn existing pavement into the base for the new roadway. According to the City of Santa Rosa’s capital projects page, the Calistoga rebuild includes roughly 4,850 linear feet of water-main replacement and about 1,500 linear feet of sewer replacement, with construction staged to keep at least some traffic moving at all times. Residents should prepare for temporary traffic controls, short-term driveway impacts, and regular schedule updates from city staff as the work progresses…
