A bridge spanning the culvert between the H and F neighborhoods in Rohnert Park, CA, has been considered by the city since the 1970s. However, the project repeatedly fell in and out of the city’s Capital Improvement Program plans, and there was no formal study of its feasibility. In 2017, the Northern California wildfires threatened the city’s northern neighborhoods as it moved south from the Sonoma Mountains. The City Council called for a reevaluation of the project, since approximately 260 homes in the neighborhoods only have single points of ingress and egress. SGA was asked by the city to assesses the feasibility of conceptual designs for a crossing between Holly Avenue and Fauna Avenue that could be regularly used by cyclists and pedestrians, while also serving as a single-lane access route for emergency vehicles. Constraints and considerations for a new bridge included adjacent homes, driveways, underground utilities, the channel’s hydraulic capacity, and a creek maintenance access by the city and the Sonoma County Water Agency. Three feasible structure types emerged from SGA’s study (i.e., steel single-span truss bridge, concrete three-span bridge, and concrete double-box culvert), and SGA developed and assessed two conceptual design alternatives for each.
