Author Greg Dwyer Organization City of Santa Rosa Address 69 Stony Circle Santa Rosa, CA 95401 Phone 707-543-3838 Project Description The project is located on Chanate Rd between Mendocino Ave and Terra Linda Dr in northeast Santa Rosa. The existing sewer pipeline was over 60 years old, difficult to maintain and located along Paulin Creek, making it susceptible to failures and sanitary sewer overflows. The sewer main was relocated to Chanate Road requiring excavation to depths of 30 feet or more. Innovative trenchless micro-tunneling technology was utilized to expedite this work, which also brought additional challenges due to the large diameter bore pits needed. There was only space for one-way traffic flow requiring a full westbound […]

Location 170 Intersection throughout Santa Rosa, CA City or County Responsible for Project Santa Rosa Author Grant Bailey Organization City of Santa Rosa Transportation and Public Works Address 69 Stony Circle Santa Rosa, CA 95401 Phone 707-543-4508 Project Description In 2021, the City of Santa Rosa completed the Battery Backup Retrofit at Various Traffic Signals project which retrofitted 170 existing traffic signal controller cabinets with a battery backup system (BBS) to provide emergency power to traffic signals in the event of a power loss. The majority of traffic signals in the City of Santa Rosa are located on collector and arterial streets that manage high volumes of traffic and also serve as emergency response and evacuation routes.
