About this file
This is a Scope of Work document for the Okaloosa County, Florida Tourist Development Department's John Beasley and Ross Marler Parking Expansion project, detailing stormwater gravity piping specifications and installation requirements. The project encompasses stormwater management infrastructure necessary to support the expansion of parking facilities at both parks, with 114 additional parking spaces planned for John Beasley Park and 113 additional spaces for Marler Park in anticipation of a new splashpad facility. The scope of work specifies the design, materials, and installation standards for gravity piping systems that will manage stormwater runoff from the expanded parking areas, including detailed specifications for pipe sizing, placement, connections, and compliance with applicable engineering standards and local regulations.
The document establishes technical requirements for stormwater gravity piping including pipe material specifications, installation methodology, depth requirements, and quality assurance standards. Contractors are required to comply with all applicable Florida Department of Environmental Protection standards and Okaloosa County ordinances governing stormwater management. The piping system must be designed to accommodate anticipated stormwater volumes from the expanded impervious surfaces while maintaining proper drainage and environmental protection. All work must be performed by qualified contractors with experience in stormwater infrastructure installation, and materials must meet specified durability and performance standards to ensure long-term functionality of the stormwater management system supporting the parking expansion project.
