Riverview Park Bridge Replacement, Cedar River

City of Renton, Washington

Hart Crowser prepared the local, state, and federal permitting documents for a pedestrian bridge crossing the Cedar River leading to the Cedar River Trail. We prepared a Biological Evaluation necessary for federal Endangered Species Act concurrence and a Stream Assessment/Critical Areas Report required under the Renton Municipal Code. Specifically, shoreline projects must demonstrate no net loss of ecological functions. To meet these requirements, a comprehensive evaluation of ecological functions within the project footprint was undertaken, including a characterization of the riparian zone, stream bank and slope stability, and all biological functions within the stream channel. Data were used to guide the design of the new bridge and develop conservation measures to mitigate for losses of riparian function.

We worked closely with engineers and City of Renton planners to produce a final design that successfully met all City, as well as state and federal requirements.  The project was successfully permitted and construction is complete.
