Section 8-523 Potentially Unstable Slopes
The following regulations apply in areas of potentially unstable slopes:
8-523.A. Required Practices. Any development proposal in a potentially unstable slope area shall evaluate the severity of slope instability. Geophysical or subsurface investigation shall be required in this evaluation. In extremely hazardous areas development shall be discouraged. In areas determined by Permit Authority to be of moderate hazard, development shall only be permitted if the applicant provides an engineered design and construction stabilization plan and appropriate maintenance measures as approved by a qualified professional geotechnical engineer or engineering geologist registered in the state of Colorado and as approved in the site plan, and if the applicant assumes the risk of damages to adjoining property or structures.
8-523.B. Prohibited Practices. Any land use in a potentially unstable slope area shall not be allowed to:
8-523.B.1. Cut into the slope without providing adequate mechanical support where necessary;
8-523.B.2. Add water to the slope that would significantly cause decreasing stability;
8-523.B.3. Provide inadequate surface and subsurface drainage;
8-523.B.4. Remove vegetation from the slope without adequate revegetation; or
8-523.B.5. Over steepen slopes by cut or fill.
