NE 192nd Street Culvert Replacement

OCI completed the alternatives analysis design and construction documents (PS&E) for a 60-foot long 12-foot by 7-foot bottomless precast culvert for Little Swamp Creek at the NE 192nd Street crossing in Kenmore, WA. The culvert will relieve persistent flooding and meets WDFW fish passage standards. The project includes: fish passable culvert design, XPSWMM H&H analysis, in-channel grading, franchise and district utility relocation, water and sanitary sewer encasement, restoration planting, permit coordination with WDFW and the Muckleshoot Tribe, and raising the roadway to provide adequate protection of the culvert. The project design documentation will be used by the City to establish a 100-year Base Flood Elevation for Little Swamp Creek. The culvert ribbon cutting ceremony was held in fall of 2017.
