Attachment_4_-_Waterway_Zone_3_(Tasks_1-3).pdf

This is a geographic information system (GIS) map document produced by Sarasota County, Florida, depicting Waterway Zone 3 and associated navigation task locations within County waterways. The map illustrates the project area encompassing Roberts Bay, Sarasota Bay, and related waterway zones, with specific task designations numbered 1 through 3 within Zone 3. The map is based on aerial imagery provided by Pictometry International with 3-inch resolution, captured between December 1, 2024, and January 13, 2025. The underlying project involves the replacement of six navigational aid markers across multiple channels: three markers in San Remo Channel, one marker in Big Pass Channel, and two regulatory markers in Lido Key Channel near Big Pass. The County has established an expedited project timeline with a required completion date of thirty days from the Notice to Proceed.

The map serves as a reference document for bidders and contractors to identify the specific geographic locations and zones where navigational aid repair and replacement work must be performed. The document carries a disclaimer that the information is representative only and does not warrant completeness or accuracy, and should not be used for navigation purposes. The coordinate system is referenced to NAD 1983 HARN State Plane Florida West (FIPS 0902) in U.S. Survey Feet, ensuring precise geographic location data for project execution and coordination among contractors and County personnel managing the waterway maintenance initiative.
