f) Requirement of a performance bond, when necessary, to ensure completion and success of proposed mitigation. x. Mitigation of alterations to habitat conservation areas shall achieve equivalent or greater biologic functions, and shall include mitigation for adverse impacts from the proposed development as appropriate. Mitigation shall address each function affected by the alteration to achieve functional equivalency or improvement on a per-function basis.
i. Forms one contiguous tract that connects on-site high value habitat areas to other on-site or off-site high value habitat areas; ii. New development proposals shall provide a minimum fish and wildlife habitat corridor width of 300 feet or a corridor width that is consistent with an approved habitat management plan; iii. In addition to the provisions of SDC 21.03.020G., development proposals on sites constrained by a fish and wildlife habitat corridor and where development already exists shall maintain a minimum fish and wildlife habitat corridor width of 300 feet unless, through an approved habitat management plan, it can be shown that a lesser habitat corridor width supports and maintains the corridor’s function and value; iv. Be contiguous with and include and/or connect critical areas, buffers, and open space tracts or wooded areas on site or on adjacent properties, if present; and v. The director may modify corridor widths based on supporting documentation from an approved habitat management plan. d. Fish and wildlife habitat corridors do not parallel Type Np streams, except as required to provide a connection between two features as described above. e. A management plan for the wildlife corridor contained within a tract or tracts shall be prepared that specifies the permissible extent of recreation, forestry or other
2. Fish and wildlife habitat corridors
On development proposal sites that contain Type F or Np streams and/or wetlands with a high habitat score greater than or equal to eight, that are also located within 200 feet of an on-site or off-site Type F or Np stream and/or wetland with a high habitat score greater than or equal to eight, a fish and wildlife habitat corridor shall be set aside and protected as follows: a. Subdivisions and short subdivisions shall either place the corridor in a contiguous permanent open space tract with all developable lots sited on the remaining portion of the project site, or shall design the lots so that conservation easements on individual lots can form a contiguous easement covering the corridor. b. Individual lots shall place the corridor in a conservation easement. c. The fish and wildlife habitat corridor shall be sited on the property in order to meet the following conditions, where feasible:
