Unless associated with another critical area, the planning director, <br />using the review process described in BMC Titlei5, Urn] Project Review Procedures, may <br />allowaltemtionof an area identified as ageologically hazardous area or <br />the setback buffers specified in the IBC if an approved geotechnicsl report demonstrates that: <br />1. The proposed development will not create a hazard to the subject property, surrounding <br />properties or rights -of -way, or erosion or sedimentation to off -site properties or bodies of water; <br />2. The proposal addresses the existing geological constraints of the site, includingan assessment <br />of soils and hydrology; <br />3. The proposed method of construction will reduce erosion potential, landslide and seismic <br />hazard potential, and will improve or not adversely affect the stability, of slopes; <br />q. The proposal uses construction techniques which minimize dismption of existing topography <br />and natural vegetation; <br />5. The proposal is consistent with the purposes and provisions of this chapter and mitigates any <br />permitted imports to critical areas in the vicinity oftheproposal; <br />6. The proposal mitigates all impacts identified in the gemeeloweal letteror geotmimical report; <br />y. All utilities and access roads or driveways to and within the site are located an as to require <br />the minimum amount of modificetionto slopes, vegetation or geologically hazardous areas; and <br />8.
