In addition to meeting applicable design requirements established in Env-Wt 307, the following design requirements shall apply to water access structures:

2. (b) Hardened shorelines shall remain intact with the exception of material that must be removed for the installation of steps to access the water;
3. (c) Where hardened shorelines do not exist, water access surfaces shall be located at an elevation at least 12 inches landward of the normal high water line;
4. (d) Beaches shall be designed such that the beach surface has zero slope;
5. (e) All water access structures other than beaches shall be sloped away from the adjacent surface water;

6. (f) Steps for access to and from a water access structure shall:

   1. (1) Not exceed 6 feet in width; and
   2. (2) Be constructed or installed such that all portions of the steps are landward of the normal high water line;

7. (g) Stairs constructed to and from a water access structure shall:

   1. (1) Not exceed 6 feet in width; and
   2. (2) If installed or constructed to provide access to the water, be removed from the lakebed prior to ice-in and not be re-installed until ice-out;
8. (h) Water access structures shall be located to avoid and minimize removal of vegetation as required by RSA 483-B:9,V(a);
9. (j) No work shall be conducted in a wetland or PRA, except as provided in Env-Wt 407;
10. (k) No new water access structures and no combination of existing and proposed structures shall use more than 20 percent of the applicant’s contiguous shoreline, up to a maximum of 50 feet; and
11. (l) Appropriate devices for diversion of stormwater away from beaches shall be installed immediately upslope of the beach.
