Rue Creek Culvert Replacement
The Pacific Conservation District received a Washington Coastal Restoration Initiative grant from the Washington State Recreation and Conservation Office. Hart Crowser assisted the District with the replacement of culverts at two locations on Rue Road in Pacific County. These culverts are fish passage barriers and occasionally flood Rue Road and surrounding residences. We provided project management and coordination, site investigations to support project design and permitting, permitting and compliance assistance, and geotechnical engineering.
Fish passage and flow conveyance capacity were restored at each site by removing the existing culverts and overlying fill, and installing a single larger, open-bottom arch or precast box culvert that meet the design requirements specified in WDFW’s Water Crossing Design Guidelines and WSDOT’s Standard Specifications for Road, Bridge and Municipal Construction and Design Manual. Hart Crowser worked closely with the project engineer to use the stream simulation approach to culvert design to ensure that the pattern, dimensions, and other features of the stream channel were preserved at the crossing, thereby enabling safe passage of juvenile and adult salmonids in up- and downstream directions.
