f. A mitigation plan is developed and implemented, per the requirements of KCC 17B.05.020E. 8. Increased wetland buffers: The Administrator shall increase wetland buffer zone widths, up to a maximum of two (2) times the standard width in the Table at KCC 17B.05.020G-1, for a development project on a case-by-case basis when a larger buffer is necessary to protect wetland functions and values. Such determination shall be based on site-specific and project- related conditions which include, but are not limited to, the following circumstances: a. Wetland sites with known locations of state priority or federally listed endangered, threatened, or sensitive species for which a habitat management plan indicates a larger buffer is necessary to protect habitat values for such species; or b. The adjacent land is susceptible to severe erosion, and erosion control best management practices will not effectively prevent adverse wetland impacts. 9. Allowed buffer uses: The following uses may be permitted within a wetland buffer without a variance provided they are not prohibited by any other applicable law, are consistent with the provisions of this Program, and they are conducted in a manner so as to minimize impacts to the buffer and adjacent wetland, including wetland functions and values: a. Conservation or restoration activities aimed at protecting the soil, water, vegetation, or wildlife. b. Passive recreation facilities designed in accordance with an approved critical area report, including: i. Walkways and trails; provided that those pathways which are generally parallel to the perimeter of the wetland shall be located in the outer twenty-five percent (25%) of the buffer area, and constructed with a surface that is not impervious to water. Raised boardwalks utilizing non-treated pilings may be acceptable; ii. Wildlife viewing structures less than five hundred (500) square feet in size. c. Stormwater management facilities, limited to stormwater dispersion facilities, outfalls and bioswales, may be allowed within the outer twenty-five percent (25%) of the buffer of Category III or IV wetlands only, provided that: i. No other location is feasible; and ii. The location of such facilities will not degrade the functions or values of the wetland. (Ord. 2016-006, 2016) 17B.05.020H Wetlands – reporting. 1. Reporting requirement: If a proposed use or development is located within three hundred (300) feet of a known or suspected wetland, a wetland critical areas report is required, and shall include the following: a. The category and precise location of the boundary of the wetland(s); and b. All wetlands and required buffers within three hundred (300) feet of the project area shall be depicted on the site plan. Best available information should include, but not be limited to, aerial photos, soils maps, and/or topographic maps; and c. An analysis of the onsite wetland(s) including the following site- and proposal-related information: i. Documentation of any fieldwork performed on the site, including, but not limited to, field delineation data sheets for delineations, the wetland rating forms, and baseline hydrologic data; ii. A description of the methodologies used to conduct the wetland delineations; and
