USACE Safeguarding Ecosystems in the Antilles - Humacao Natural Reserve, Río Antón Ruíz restoration project
Each weir will have a 16 x 22 inch concrete cap and a 3 x 15 foot notch, allowing for continued vessel and fauna transit. The advantage of the design is that it can be adapted for sea level rise by constructing additional height uniformly across the entire length of the respective weir.
