determined through the site-specific geological assessment, but in no case shall be less than twenty- five feet from the top of slopes of twenty-five percent and greater. 2. Any proposed alteration that would result in the creation of or which would increase or exacerbate existing geological hazards,or which would result in substantial unmitigated geological hazards either on-site or off-site shall be prohibited. F. Geological Assessment.A geological assessment is a site investigation process to evaluate the on- site geology affecting a subject property and contiguous properties and the extent to which geological factors may be impacted by the proposed development activity. 1. A field investigation and geological assessment shall be completed under the responsible charge of a geologist to evaluate whether or not an active geological hazard arca exists within two hundred feet of the site. a. The geological assessment shall be submitted in the form of a geotechnical letter when the geologist finds that no active geological hazard arcya 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. geologist finds that an active geologically hazardous argia 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. 2--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. 2.. 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. photo analysis, review of public records and documentation,and interviews with adjacent property owners or others knowledgeable about the area, etc. hazardous as set forth in subsection A of this section, Designation. 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 eetld-result from the proposed development either on site or off site. For lane 'e . . - - -- , •- 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. 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 site and adjacent properties on a long term Planning Commission Resolution 19-04 Page 28 Critical Areas March 19, 2019
