All applications for permits to conduct activities having a possible significant impact on critical areas that are located on or near a project site must identify the areas affected and make an estimate of the probable impact. The city of Cle Elum shall deny all requests for permits which would result in activities degrading a wetland or fish and/or wildlife habitat conservation area, which would put people or property in a position of unacceptable risk with respect to floods or geologic hazards, which would tend to aggravate geologic hazards, or which would harm critical recharging areas for aquifers. The city of Cle Elum may, however, grant permits which include mitigation measures if the mitigation measures adequately protect the critical area and people involved. In granting a permit that includes mitigation measures, best available science, which shall be determined utilizing the criteria set out in WAC 365-195-900 through 365-195-925, shall be used to develop and approve the mitigation measures. Applicable permit fees, as set forth by resolution of the city council, are due at the time of application.
