feature or its designated buffer area. <br />2. Determination of Sensitive Area. To assist with the administration of these <br />provisions, the City has prepared a map indicating sites that appear to meet the above criteria. The <br />Public Work's Director, or designee, shall use this map to make a preliminary determination of a <br />site's sensitive area status. The map is on file at the City's Public Works Engineering Department <br />(858 Pearl Street) and Permit & Information Center (99 West 10th Avenue). <br />An applicant may challenge the Director's preliminary determination that a site is a sensitive <br />area through submission of actual field or site information that demonstrates to the City's satisfaction <br />that the site's existing physical features, such as a continuous vegetative perimeter buffer which <br />prevents discharge of sediments, mitigate potential stormwater quality impacts, and the Director shall <br />thereafter make a final determination of whether the site is a sensitive area. <br />If an applicant chooses not to contest-the designation or is unable to satisfy the above criteria, <br />the site shall be considered a sensitive area and an erosion prevention permit shall be required. <br />3. Appeal of designation. An applicant who disagrees with the Director's final <br />determination may appeal that decision within the time and manner prescribed in section R-6.645- <br />F.11 of these Rules. <br />R-6.645-F Erosion Prevention Permits. <br />1.
