The project-specific information required by Env-Wt 310.01(c)(1) or Env-Wt 311.03(b)(11), as applicable, for a bank/shoreline stabilization project shall be as follows:

1. (a) A narrative and photos that:

   1. (1) Describe and illustrate existing conditions and locations where shoreline vegetation currently exists;
   2. (2) Identify all known causes of erosion to the bank/shoreline in that location;
   3. (3) Identify information and, for minor and major projects, engineering standards used to determine the appropriateness of the proposed bank stabilization treatment or practice;
   4. (4) Explain the design elements that have been incorporated to address erosion, by eliminating or minimizing the causes therefor; and
   5. (5) For minor and major bank/shoreline stabilization projects or minimum impact bioengineering stream bank projects, identify the flood risk tolerance of the proposed treatment or practice using the appropriate technical guidance or national engineering handbook;

2. (b) A cross-section plan that shows:

   1. (1) The difference in elevation between the lowest point of the bank/shoreline slope to be impacted by the construction and the highest point of the bank/shoreline slope to be impacted;
   2. (2) The linear distance across the proposed project area as measured along a straight line between the highest and lowest point of the bank/shoreline slope to be impacted;
   3. (3) The existing and proposed slope of the bank/shoreline; and
   4. (4) The normal high water line or ordinary high water mark, as applicable;

3. (c) Hard-scape, rip-rap, or unnatural design plans shall include:

   1. (1) Designation of minimum and maximum stone size;
   2. (2) Gradation;
   3. (3) Minimum rip-rap thickness;
   4. (4) Type of bedding for stone;
   5. (5) Cross-section and plan views of the proposed installation;
   6. (6) A description of anticipated turbulence, flows, restricted space, or similar factors that would render vegetation and bioengineering stabilization methods physically impracticable;
   7. (7) Engineering plans for rip-rap in excess of 100 LF along the bank or bed of a watercourse, including in-stream revetments, stamped by a professional engineer; and
   8. (8) If the project proposes rip-rap adjacent to great ponds or other surface waters where the state holds fee simple ownership to the bed, a stamped surveyed plan showing the location of the normal high water line and the footprint of the proposed project; and

4. (d) Design plans for a wall shall include:

   1. (1) Cross-section and plan views of the proposed installation and sufficient plans to clearly indicate:

      1. a. The relationship of the project to fixed points of reference, abutting properties, and features of the natural shoreline; and
      2. b. The dimensions of the existing wall, if any, and of the proposed wall; and
   2. (2) If the application is for a wall adjacent to a great pond or other surface water where the state holds fee simple ownership to the bed, a surveyed plan, stamped by a licensed land surveyor, showing the location of the normal high water line and the footprint of the proposed project.
