About this file
This document is a Project Design Criteria (PDC) specification for Activity 1 Shoreline Stabilization projects in Jacksonville/Florida, establishing environmental and technical standards for waterfront construction work. The PDCs govern new shoreline stabilization projects limited to 500 feet in length, with seawalls and footers restricted to 1.5 feet waterward from Mean High Water (MHW) unless alignment with adjacent seawalls is necessary. The criteria cover repair and replacement of existing vertical seawalls without length restrictions, installation of stabilization materials including riprap, articulating blocks, mats, sand cement, and geotextile fabrics that may not extend more than 10 feet waterward of MHW. Additional covered activities include removal and filling of upland cut boat ramps, slips, and basins to restore natural shoreline contours or align with adjacent properties, as well as installation, repair, replacement, and removal of seawall footers.
The PDCs establish specific technical and environmental requirements including backfill limitations to leveling operations necessary for land behind seawalls or riprap, mandatory hand placement of stabilization materials around red mangrove prop roots, and slope requirements of 2:1 Horizontal to Vertical for riprap structures. The criteria explicitly exclude groins, jetties, perpendicular shore structures, and beach nourishment activities, while prohibiting shoreline protection on ocean beaches designated for sea turtle nesting. Within the Florida Keys National Marine Sanctuary (FKNMS) boundaries, riprap placement below MHW requires NOAA permit authorization demonstrating consistency with the Marine Protection, Research, and Sanctuaries Act of 1972, with proof of FKNMS approval required during project-level review.

Project Design Criteria (PDCs) specific to Activity 1 for Shoreline Stabilization
A1.1. Activities covered by this Opinion include:
A1.1.1. New shoreline stabilization: New shoreline stabilization projects cannot exceed 500 ft in length. New seawalls and footers cannot extend any further waterward than 1.5 ft (18 in) from MHW, unless necessary to align a new seawall with 1 or more adjacent seawalls.
Repair or replacement of existing vertical seawalls: The repair, and replacement of seawalls and footers cannot extend any further waterward than 1.5 ft (18 in) from the wet face of the existing seawall or MHW, unless necessary to align with 1 or more adjacent seawalls. The repair or replacement of an existing seawall is not restricted to the 500 ft in length limit in PDC A1.1.1.
A1.1.2. Shoreline stabilization materials may consist of riprap, articulating blocks or mats, and sand cement, geotextile/ filter fabric and mattresses. Installation of new shoreline stabilization materials where none previously existed may not extend more than 10 ft waterward of MHW (including the toe of the riprap). Riprap repair, and replacement may occur at its previous location, upland of, or within 1.5 ft (18 in) waterward of its previous location.
A1.1.3. The Opinion does not cover removal of any length of seawall or other shoreline stabilization materials if such removal would result in an unstabilized shoreline.
A1.1.4. The Opinion covers installation, repair, replacement, and removal of seawall footers.
A1.1.5. This Opinion covers the removal/fill of upland cut boat ramps, slips, and basins to return the shoreline to the natural contour and/or to bring the shoreline into alignment with the adjacent property shorelines.
The following PDCs apply to all the activities described in PDC A1.1 above:
A1.2. Placement of backfill is limited to those situations where it is necessary to level the land behind seawalls or riprap. This includes backfill associated with installation of a seawall or riprap to remove/fill in an upland cut area (e.g., boat slip, boat ramp, boat basins) to return the shoreline to the original shape or to connect to adjacent seawalls to bring the shoreline into alignment with adjacent property shorelines.
A1.3. Shoreline stabilization materials must be placed by hand around red mangrove prop roots.
A1.4. Shoreline stabilization structures, other than vertical seawalls, shall be no steeper than a 2:1 Horizontal: Vertical slope for riprap, or the appropriate slope necessary to ensure shoreline stability while minimizing the total footprint when using materials other than riprap.
A1.5. Installation and/or repairs to groins, jetties, or other structures placed perpendicular to shore, and beach nourishment/renourishment are not covered in this Opinion.
Breakwaters/living shorelines are covered as described in Activity 7.
A1.6. No placement of riprap below MHW is covered under this Opinion within the boundary of the FKNMS unless the FKNMS issues a NOAA permit or authorization that signifies the proposed activity is consistent with Title III of the Marine Protection, Research, and Sanctuaries Act of 1972, as amended. Proof of approval from the
FKNMS is required as part of the project level review submission, described in
Section 2.3, below
A1.7. Shoreline protection shall not occur on ocean beaches used for sea turtle nesting.
A1.7. Shoreline protection shall not occur on ocean beaches used for sea turtle nesting.
