§ 155.031 DETERMINATION OF SITES WITH ENVIRONMENTAL CONSTRAINTS.

   (A)   Identification of environmental constraints. Applications for land disturbing activities not exempted in § 155.017 shall include a checklist indicating the presence or absence of the following features on the site to be developed:

      (1)   Local regulatory conveyance zone/regulatory flood plain, as defined by local ordinance;

      (2)   Protected waterways subject to the protection standards in §§ 155.065 through 155.071;

      (3)   Lakes and impoundments of one acre or greater;

      (4)   Wetlands with a surface area of 0.1 acre or greater and subject to the protection standards in §§ 155.065 through 155.071;

      (5)   Karst features subject to development restrictions as defined in §§ 155.085 through 155.092; and

      (6)   (a)   Steep slopes 20% or greater.

         (b)   Unstable soils as determined by the Natural Resources Conservation Service and depicted on Core Graphic 5.

         (c)   The presence of any of these environmentally constrained features shall be confirmed by reference to the best available federal, state, or county mapping and resources (for example, floodplain or LOJIC maps) as determined by the Planning Director or as confirmed by a site-specific survey conducted by a qualified professional.

   (B)   Determination of sites with environmental constraints. A development site that contains one or more of the environmentally constrained features listed in division (A) above shall be designated a “site with environmental constraints.”

   (C)   Approval required. The Planning Director, or designee, shall approve all determinations of sites with environmental constraints. The Director may require a site-specific survey if the Director determines that the magnitude of the development, its potential environmental impacts, or inadequacy of the best available mapping justify more detailed identification of constrained areas.
