This file is a CCTV inspection video documenting the 45th Ave SW culvert in southwest Seattle, Washington, captured as part of the project assessment for the 45th Ave SW Culvert Replacement and Habitat Restoration initiative. The video provides a downstream to upstream visual inspection of approximately 201.5 feet of the culvert located at 9144 45th Ave SW, between SW Director Street on the north and SW Wildwood Place on the south. This inspection serves as supporting documentation for the project planning and bidding process, enabling contractors and project stakeholders to assess the existing culvert condition prior to replacement.

The project encompasses comprehensive civil demolition, in-stream bypass installation, tree protection measures, site work, stream work, grading, utilities (drainage and water), roadway paving, landscaping, and structural components including soldier pile shoring, cast-in-place concrete footings, shotcrete walls, and precast concrete covers, along with electrical work. The Engineer's Estimate for the complete culvert replacement and habitat restoration project is $30,250,000, with the CCTV inspection video serving as critical baseline documentation for bid preparation and project scope validation.
