This section shall apply to any geologic hazard investigation for the purpose of determining the feasibility of land use approval for a concept plan; preliminary or final plat approval; a commercial, institutional or one-, two- or multi-family dwelling conditional use permit; site plan approval; or for the purpose of exploring, evaluating or establishing locations for permanent improvements. A geologic hazard report shall be submitted to the county as part of the land use application, pursuant to the requirements of this subchapter, for any proposed development in a geologic hazard study area.
(A) (1) Prior to a land use application, the applicant shall schedule a scoping meeting with the county to evaluate the engineering geologist’s or geotechnical engineer’s investigative approach. The investigation approach shall allow for flexibility due to unexpected site conditions. Field findings may require modifications to the work plan. Upon completion of a scoping meeting, an application for an excavation or grading permit, as necessary, may be submitted to the county. At this meeting, the applicant shall present a work plan that includes the locations of anticipated geologic hazards and proposed subsurface exploratory excavations, such as test pits, trenches, borings and cone penetrometer test (CPT) soundings, which meet the minimum acceptable regional standards of practice, this subchapter, the adopted appendices on file with the County Clerk, and includes:
(a) A property location map;
(b) A geologic map;
(c) A topographic map with contours;
(d) A slope map or lidar imagery, if available;
(e) A map showing the location of the proposed development, including structures, roads, depths of basements and foundations and the like; locations of proposed subsurface exploration, such as trenches, borings, test pits and the like; with a description of the proposed development; and
(f) A map showing the slope stability analysis cross-section locations.
(2) The applicant’s professional consultants will find geologic information available from the UGS and other sources useful in planning site development, preparing for the scoping meeting and in performing geologic hazard investigations. Available UGS information includes:
(3) Lidar elevation data are available at (https://gis.utah.gov/data/elevation-and-terrain/) and (http://opentopography.org).
(B) The county will arrange for a state-licensed professional geologist, specializing in engineering geology, to attend the scoping meeting on behalf of the county, at the applicant’s expense. The county’s geologist will provide verbal feedback to the applicant and consultants regarding the proposed work plan and the requirements of this subchapter. Reimbursement to the county for the direct costs of any outsourced staff shall be paid by the applicant prior to the acceptance of a land use or building permit application.
(C) As required by this code and except as otherwise noted herein, no person shall commence or perform any land disturbance, grading, excavation, relocation of earth or any other land disturbance activity, without first obtaining an excavation or grading permit. Application for an excavation or grading permit shall be filed with the county on forms furnished by the county for such purposes only after a scoping meeting has taken place.
(D) The applicant shall specify a primary contact responsible for coordination with the county during the land disturbance activities.
