FRONT PLAN VIEW VER: 201407 Key' for Construction Conditions for Docks or Other Minor Structures Constructed in or Over Johnson's Seagrass (Halophila johnsonii) National Marine Fisheries Service/U.S. Army Corps of Engineers October 2002 la. The construction site is within the known range of Johnson's seagrass occurrence (Sebastian Inlet to central Biscayne Bay in the lagoonal systems on the east coast of Florida). Go to 2. lb. The construction site is not within the known range of Johnson's seagrass occurrence but submerged aquatic vegetation (SAV) is present at the site. Use `Dock Construction Guidelines in Florida for Docks or Other Minor Structures Constructed in or over Submerged Aquatic Vegetation, Marsh or Mangrove Habitat" - U.S. Army Corps of Engineers/National Marine Fisheries Service, August 2001. lc. The construction site is not within the range of Johnson's seagrass and SAV is not present at the site: No construction conditions for SAV are necessary. 2a. Seagrass survey for Johnson's seagrass is performed at the proposed site during the April 1— August 31 growing season. Go to 3. 2b. No survey for Johnson's seagrass is performed at the proposed site during the growing season, or a survey is performed at the proposed site but is outside of the growing season. Go to 4. 3a. Johnson's seagrass is present at the proposed construction site. Go to 5. 3b. Johnson's seagrass is not present at the proposed construction site. Go to 6. 4a. The construction is in an area designated by the National Marine Fisheries Service - Protected Resources Division (NMFS-PRD) as critical habitae for Johnson's seagrass.

'- Light -transmitting materials are made of various materials shaped in the form of grids, grates, lattices, etc., to allow the passage of light through the open spaces. All light -transmitting materials used for dock construction in the known range of Johnson's seagrass shall have a minimum of forty-three (43) percent open space.
