Geologically Hazardous Areas. Areas that, because of their susceptibility to erosion, sliding, earthquake, or other geological events, pose unacceptable risks to public health and safety and may not be suited for commercial, residential, or industrial development.
Geologically Hazardous Areas. I. Structures and improvements shall minimize alterations to the natural contour of the slope, and foundations shall be tiered where possible to conform to existing topography. 2. Structures and improvements shall be located to preserve the most critical portion of the site and its natural landforms and vegetation. 3. The proposed development shall not result in greater risk or a need for increased buffers on· neighboring properties. 4. Development shall be designed to minimize impervious surfaces within the critical area and critical area buffer. See B.1.a-h. of the submitted SEPA checklist.
Geologically Hazardous Areas. Based on published geologic maps, the site and surrounding vicinity consists of almost entirely of mass-wasting deposits resulting from significant landslide events. Geomorphic features noted at the project site during our preliminary research and confirmed during field reconnaissance are consistent with large scale slump-block landslides. The classic characteristics of landslides can be readily seen, including clearly identifiable head scarps, rotated slump blocks, and hummocky topography of the slide mass. It is believed that the landslide events occurred under notably different geologic and climactic conditions during the end of the Pleistocene Epoch. The noted slump-block failures and surrounding mass wasting deposits from older landslide events appear to be relatively stable under the modern day geologic and climate conditions. A full report has been completed as is found in Appendix F. Additional site-specific exploration and analyses will be performed as part of the development phases of this project and will comply with the requirements of CCC 11.86.

A full report has been completed as is found in Appendix F. We have also included a geotechnical memorandum dated December 19, 2019 along with a Site Features and Geologic Constraints map in response to comments received from Chelan County as part of the previous submittal of this project. Additional site-specific exploration and analyses will be performed as part of the development phases of this project and will comply with the requirements of CCC 11.86.
Geologically Hazardous Areas. The provisions of PCC Section 18E.080 (effective July 16, 2012) shall apply except as modified below. Due to site geologic conditions documented from extensive site-specific study, the 30 percent or steeper slope criterion for landslide hazard area determination in PCC 18E.80.shall be changed to 40 percent as it applies to the Project Site and requirements of the code.
