About this file
This is a technical reference guide attachment for a Navigational Aid Repair Project issued by Sarasota County, Florida. The document provides detailed construction diagrams and specifications for various water navigation markers used within County waterways. The guide includes specifications for six navigational aid markers comprising three markers in the San Remo Channel, one marker in the Big Pass Channel, and two regulatory markers in the Lido Key Channel near Big Pass. The markers detailed in the diagrams include small green dayboards, small red dayboards, large red dayboards, large green dayboards, and regulatory sign combinations, with each type illustrated with specific dimensional and material requirements. The project must be completed within thirty (30) days of the County's Notice to Proceed.
The diagrams specify construction materials and components for each marker type, including pressure-treated lumber (2"x4" and 4"x4"), plastic or wood pilings, 316 stainless steel through bolts, plastic wrap, reflective strips, and caps. Marker heights range from 6 feet to 6 feet 6 inches above the mean high water line, with 8-inch diameter pilings and various cross-member hardware specifications. The reference guide serves as the technical standard for construction and replacement of these navigational aids, ensuring consistency and compliance with waterway navigation requirements across Sarasota County's specified channels.
