This document is a set of engineering and survey plans for the 2024 South Naples Construction of Emergency Dunes on Beaches, prepared for the Collier County Board of County Commissioners. The project covers beach restoration from reference monuments R-79 to R-89, located along the Gulf of Mexico coastline in Naples, Florida. The plans include detailed topographical cross-sections, baseline measurements, and elevation profiles for multiple survey monuments, showing existing beach conditions and proposed emergency dune construction. The plans are dated 8/16/24 and prepared by APTIM Environmental & Infrastructure, LLC, with precise geographical coordinates, elevation data, and beach profile measurements for each referenced monument.

The technical drawings provide comprehensive details about the emergency dune construction, including landward and waterward berm crests, toe of fill locations, and mean high water (MHW) elevations. Each monument's cross-section includes specific elevation data, with crest elevations consistently set at 6' NAVD (North American Vertical Datum) and mean high water at +0.33' NAVD. The project appears to be a coastal protection and erosion mitigation effort, with careful documentation of existing beach topography and planned interventions. The plans include aerial imagery showing residential areas, parcel lines, and the proposed construction zones, suggesting a strategic approach to beach restoration that considers both environmental and property considerations.
