(1) All new major development within Class II wildlife habitat conservation areas may require the filing of a habitat management plan (HMP). An HMP shall consider measures to retain and protect the wildlife habitat and shall consider effects of land use intensity, buffers, setbacks, impervious surfaces, erosion control and retention of natural vegetation. The requirement for an HMP shall be determined during the SEPA threshold determination on the project and/or by the review authority.

(2) Land Disturbing Activities. Land disturbing activities located within the jurisdiction of critical areas shall obtain a certificate of compliance and provide for storm water quality and quantity control, including preparation of a temporary erosion and sediment control plan and permanent drainage plan, consistent with the Stormwater Management Manual for the Puget Sound Basin, prepared by the State Department of Ecology, February, 1992, as amended. This requirement may be waived by the Administrator upon determination that the proposal will not affect the critical area.

(3) Zoning or Comprehensive Plan Amendment. Prior to taking action on a zoning or comprehensive plan map amendment, the applicant shall complete an environmental assessment that shall be approved by Clallam County, to confirm the nature, extent and rating of critical areas on the property; determine if the subsequent development proposal would be consistent with this chapter; and determine whether mitigation or other measures would be necessary if the proposal were approved. Such review shall occur prior to any SEPA threshold determination pursuant to Chapter 27.01 CCC, Clallam County Environmental Policy. Findings of such review may be used to condition or mitigate the impact through the SEPA threshold determination or to deny the proposed zoning or comprehensive plan map amendment if the impacts are significant and cannot be mitigated.
