WHAT THEY WANT
(Summarized from the RFP)
Clark County is seeking a qualified consultant team to provide professional engineering design and environmental documentation and permitting services for the NE Allworth Road Rock Creek Crossing Improvements project, located at NE Allworth Road at NE 209th Avenue. The project addresses two deteriorating corrugated metal pipe culverts — a 60-inch and a 36-inch diameter pipe — both with heavily corroded bottoms, severe roadway embankment scour, and visible ground movement. The scope requires replacing these culverts with a new structure spanning Rock Creek that meets 100-year flood hydrologic conditions and fish passage requirements, and rebuilding the roadway surface.
