A. Severe Constraint Lands are extremely sensitive to development, surface disturbance such as grading, filling, or vegetation removal has high potential to threaten life or property, whenever possible, alternative development should be considered.
B. New structures are not allowed on Severe Constraints Lands.
C. Other development of land or approval for a Planning Commission action shall be allowed only when the following study has been accomplished. An engineering geologic study approved by the Wellsville City Engineer establishes that the site is stable for the proposed use and development. The study shall include the following:
1. Index map.
2. Project description to include location, topography, drainage, vegetation, and discussion of previous work and discussion of field exploration methods.
3. Site geology, based on a surficial survey, to include site geologic maps, description of bedrock and surficial materials, including artificial fill, locations of any faults, folds, etc., and structural data including bedding, jointing and shear zones, soil depth and soil structure.
4. Discussion of any off-site geologic conditions that may pose a potential hazard to the site, or that may be affected by on-site development.
5. Suitability of site for proposed development from a geologic standpoint.
6. Specific recommendations for cut slope stability, seepage and drainage control or other design criteria to mitigate geologic hazards.
7. If deemed necessary by the engineer or geologist to establish whether an area to be affected by the proposed development is stable, additional studies and supportive data shall include cross-sections showing subsurface structure, graphic logs with subsurface exploration, results of laboratory test and references.
8. Signature and registration number of the engineer and/or geologist licensed as professional engineer in the State of Utah.
9. Additional information or analyses as necessary to evaluate the site.
D. Prohibited Actions: Notwithstanding any other provision of these Ordinances it shall be unlawful to clear, "grub," grade, fill, or excavate any land in any manner which presents an unreasonable risk of erosion, flooding, landslide, or any other unsafe condition; and it shall be unlawful to erect any structure which will not be reasonably safe for use as a human habitation because of:
1. Proximity to a high water table (water close to the ground surface);
2. Surface water;
3. Expansive soils;
4. Collapsible soils;
5. Proximity to a potential landslide area;
6. Proximity to a secondary fault;
7. Proximity to an alluvial fan;
8. Proximity to an active landslide;
9. Proximity to a primary Wasatch Fault zone;
10. Any other unsafe condition, as determined by the City. (Ord. 2019-04, 10-16-2019)
