The Chester Creek culvert underneath Northern Lights Blvd failed during the winter of 2020. As a fast paced, emergency repair project, CRW provided design for long-term replacement. Some of the services performed were hydraulic analysis, permitting and environmental impact analysis, flood hazard analysis, stream realignment, rip rap, fish habitat permitting, traffic control analysis, utility impact analysis, relocation of the water main which runs below the culvert, and plans, specifications, and cost estimate. Construction was completed during the allowed fish window. The high-power, overhead electric transmission lines were able to remain in place during construction, saving both time and money.
