Attachment_3_Additional_Navigational_References2.pdf

Attachment 3 is a technical document titled "Additional Navigational References" from Sarasota County, Florida, containing six detailed engineering diagrams for waterway markers and navigational aids (ATON). The diagrams provide comprehensive technical specifications for various sizes and types of navigational markers, including small and large ATON configurations, uniform waterway marker details, single and double pile installations, and special signage like a "Dangerous Inlet" marker. The drawings include precise measurements, materials specifications (such as stainless steel bolts, reflective strips, composite or wood piling), and installation guidelines for marine navigation infrastructure.

The technical drawings are part of a project for repairing navigational markers in Sarasota Bay and Lemon Bay, with detailed engineering specifications that appear to be supporting documentation for a county contract opportunity. The diagrams specify technical requirements for marker construction, including dimensions ranging from 3'x4' to 5'x7', with variations in pile configuration, mounting hardware, and surface treatments. The drawings include notations about substrate conditions, water line references, and installation considerations for different marine environments, suggesting a comprehensive approach to navigational marker design and deployment that accounts for varying geographical and maritime conditions.
