3. When the geological assessment has been accepted, the Department shall issue a decision on the land use permit application as provided for in EMC Title 15, Local Project Review Procedures. 4. A geological assessment for a specific site may be valid for a period of up to five years when the proposed land use activity and site conditions affecting the site are unchanged. However, if any surface and subsurface conditions associated with the site change during that five-year period or if there is new information about a geological hazard, the applicant may be required to submit an amendment to the geological assessment. 5. A geological assessment shall include a field investigation and may include the use of historical air photo analysis, review of public records and documentation, and interviews with adjacent property owners or others knowledgeable about the area, etc. 6. A geological assessment shall include the following minimum information and analysis: a. An evaluation of any areas on the site or within 200 feet of the site that are geologically hazardous as set forth in subsection A: Geologically Hazardous Area Designation [37.080(A)].. b. An analysis of the potential impacts of the proposed development activity on any geologically hazardous area. The analysis shall include information regarding any potential geological hazard that could result from the proposed development either on site or off-site. For landslide hazard areas, the analysis shall consider the run -out hazard of landslide debris to the proposed development that starts upslope, whether the slope is part of the subject property or starts off-site. c. Identification of any mitigation measures required to eliminate potentially significant geological hazards both on the proposed development site and any potentially impacted off-site properties. When hazard mitigation is required, the mitigation plan shall specifically address how the proposed activity maintains or reduces the pre- existing level of risk to the site and adjacent properties on a long term basis. The mitigation plan shall include recommendations regarding any long term maintenance activities that may be required to mitigate potential hazards. d. The geological assessment shall document the field investigations, published data and references, data and conclusions from past geological assessments, or geotechnical investigations of the site, site-specific measurements, tests, investigations, or studies, as well as the methods of data analysis and calculations that support the results, conclusions, and recommendations. e. The geological assessment shall contain a summary of any other information the geologist identifies as relevant to the assessment and mitigation of geological hazards. 7. Geological assessments shall be prepared under the responsible charge of a geologist, and signed, sealed and dated by the geologist. (This section shall be codified as EMC 19.37.080.)
