e. The facilities must include a buffer enhancement and management plan that would improve the functional performance of the buffer and associated critical area. f. All site development plans should consider low impact stormwater management techniques where site conditions allow as described in the Low Impact Development Technical Guidance Manual for Puget Sound, January 2005. For Type Np and Ns streams and Category II, III, and IV wetlands, the Planning Director may grant an exception to the outer 25% limitation when the applicant demonstrates that the project would significantly increase wetland or stream function and would not substantially alter stream or wetland hydrology. A significant increase in wetland function shall be defined as no reduction in any individual function as measured by the Western Washington Wetland Rating System, and at least a 5 point overall increase in the combined function score as measured by the Western Washington Wetland Rating System. (This section shall be codified as EMC 19.37.070.) Section 7: Submittal requirement—Supporting information. A. Submittal Requirements. Applications for land uses or developments proposed on lots on or adjacent to critical areas shall be filed with the planning department. The city may waive specific submittal requirements determined to be unnecessary for review of a specific application. All developments proposed on lots which may contain or adjoin critical areas and/or buffers shall be evaluated by the applicant to provide the information necessary for the planning department to determine if and to what extent the site contains critical areas. B. Supporting Information. All land uses and developments proposed on or adjacent to critical areas and their buffers shall include studies which describe the environmental conditions of the site. No activity, including clearing, filling or grading, shall be permitted until the information required by this section is reviewed and approved by the city. Such studies shall be prepared by experts with demonstrated qualifications in the area of concern, who shall prepare the studies in accordance with the requirements of this chapter to the satisfaction of the planning department. The city may retain consultants at the applicant's expense to assist the review of studies and/or conduct site evaluations which are outside the range of staff expertise. The planning director is authorized to develop and maintain a detailed list of required study contents. Section 8: Geologically hazardous areas. A. Designation. Except for geologically hazardous areas regulated by the Shoreline Master Program, the following geologically hazardous areas shall not be altered except as otherwise provided by this chapter: 1. Landslide hazard areas: a. Those areas defined as high, and very high/severe risk of landslide hazard in the Dames and Moore Methodology for the Inventory, Classification and Designation of Geologically Hazardous Areas City of Everett, Washington: July 1, 1991: 14
