a. The geological assessment shall be submitted in the form of a geotechnical letter when the geologist finds that no active geological hazard area exists on or within two hundred feet of the site.The geotechnical letter shall meet the minimum required content and shall be in the format established by the director. b. The geological assessment shall be submitted in the form of a geotechnical report when the geologist finds that an active geologically hazardous area exists on or within two hundred feet of the proposed project area.The geotechnical report shall meet the minimum requirements established by the director pursuant to Section 19.37.070 of this chapter. 12. Geological assessments shall be submitted to the department for review and approval as part of the integrated permit review process described in EMC Title 15, Local Project Review Procedures. The department shall review the geological assessment and either: a. Accept the geological assessment; or b. Reject the geological assessment and require revisions or additional information. Th. 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. 34. 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 knowledg able about the area,etc. 6. A geological assessment shall include the following minimum information and analysis: a. An evaluation of any ar as on the site or within two hundred feet of the site that are geologically hazardous as set forth in subsection A of this section, Designation. 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 ar as,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 preexisting level of risk to the 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 ecommendatio c. 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. EMC Title 19.37 (Critical Areas) Page 26
