About this file

Written by GovTribe AI ·

These are construction drawings for the Broward County, Florida Boulder Reef Construction Project, prepared by Foth Infrastructure & Environment, LLC and APTIM, dated June 4, 2025. The project involves constructing boulder reefs in offshore and nearshore areas of the Atlantic Ocean near Fort Lauderdale and Lauderdale-by-the-Sea. The project area covers approximately 5.97 acres, including 5.52 acres in the nearshore area (3.70 acres of net boulder coverage) and 0.45 acres in the offshore area. The drawings provide detailed specifications for boulder placement, including using clean limestone boulders with diameters of 4-6 feet, placed in a single layer with the flattest surface down and oriented parallel to the existing bottom.

The construction plans include precise geographic coordinates for multiple acceptance sections, detailing wind and wave data, predicted tides for 2026, and specific placement requirements. The boulders will be strategically distributed across different reef zones (inner, middle, and outer reefs), with careful consideration of existing mitigation reefs and hardbottom areas. Construction notes emphasize environmental considerations, such as using clean rocks free of pollutants, minimizing rock stacking, and ensuring rocks are not indiscriminately dumped. The project aims to create artificial reef structures that will potentially support marine ecosystem development while maintaining specific technical and environmental standards.
