Santa Rosa details $122.7 million Kalisoga Road rehabilitation, work to run through August 2027

City of Santa Rosa officials detailed the Kalisoga Road Pavement Rehabilitation and Utility Improvement Project at a community meeting, saying construction began June 8 and is expected to be complete in August 2027.

Peter Parado, project manager with the Santa Rosa City Transportation and Public Works Department, said the work will rebuild about 1.1 miles of Kalisoga Road between Monaceto Boulevard and Highway 12, improve ADA curb ramps, upgrade bus stops and add buffered, and in places protected, bike lanes. "This project focuses on improving approximately 1.1 miles of Kalisoga Road between Monaceto Boulevard and Highway 12," Parado said.

The construction cost is estimated at $122.7 million, and Parado said the project is funded in part through the state’s Road Repair and Accountability Act as cited in project materials. The city will use full depth reclamation (FDR) for travel and center lanes — a method that grinds and reuses existing roadway materials — and a mill-and-fill approach for parking and bike lanes. "Because we're recycling and reusing the existing material on site, there is less hauling in and out," construction manager Mike Janet said, describing the environmental and cost advantages of FDR.

Janet gave specific utility quantities: crews will replace and upsize about 7,629 linear feet of water pipe and replace approximately 825 linear feet of sewer pipe before paving begins. He also explained the need to "raise iron" — adjusting manhole frames and valve boxes to match the new roadway elevation after paving.

Work is phased to limit disruption. Janet said crews mobilized the first week and began potholing to locate utilities before major pipeline work. Typical work days will be Monday through Friday, 7:00 a.m. to 5:30 p.m., and the team will provide advance notice of lane closures and major paving operations through a weekly newsletter and the project website.

The city emphasized that emergency access will be maintained and that the contractor and public-safety agencies are coordinating daily to preserve ingress and egress through active work zones. "Emergency access and egress will be maintained at all times throughout the project," Janet said.

Residents can find plans, construction updates, FAQs and sign up for the newsletter at the project website (kalisogarroad.com/kalisogarroadpro and the city's capital projects page), and can contact the project team at info@calisogaroadpro.com or the project information line provided in meeting materials. Staff said slides and a recorded video of the presentation will be posted shortly on the project site.

The city said the work will include new and upgraded crosswalks, bus stop improvements and a two-way protected cycle track near Sequoia Elementary; details including final striping, bollards and locations will be phased by construction segment. The city plans to evaluate post-construction speeds and other conditions and may pursue changes such as speed-limit adjustments once the built improvements are in place.
