These engineering and construction documents are for the Oregon Department of Transportation (ODOT) Sylvan Maintenance Station New Fuel Tank project located at 6000 SW Raab Rd in Portland, Oregon. The project involves constructing a new 12,000 gallon underground fuel tank with multiple compartments, including installations for diesel and regular fuel, along with associated site improvements such as stormwater management, drainage systems, utility infrastructure, landscaping, and site demolition. The comprehensive plan includes detailed specifications for site preparation, tank foundation, utility trenches, concrete work, erosion control, and environmental compliance measures.

The project documents outline specific technical requirements for fuel tank performance, including specifications for tank materials, leak detection, venting systems, and environmental protections. The plans indicate considerations for site-specific challenges such as existing utilities, topographical constraints, and stormwater management. The drawings provide intricate details on construction methods, including catch basin designs, planter installations, pavement sections, and utility trenching. While no specific budget is explicitly stated in the documents, the level of detail suggests a significant infrastructure investment focused on meeting strict engineering, safety, and environmental standards for a state transportation maintenance facility.
