When there is a reasonable probability that a project will affect or be affected by carbonate geologic hazards, the Board of Supervisors shall require submission of a hydrogeologic report. In reaching a determination of whether a project will affect or be affected by carbonate geologic hazards, the Board of Supervisors shall consider the presence or absence of carbonate features in the vicinity of the project, the testimony of qualified expert witnesses, and such other reasonable information as may be available. When a hydrogeologic report is required, an aquifer test (see §
160-65) shall also be required. All hydrogeologic reports shall be prepared at the applicant's expense by a licensed geologist qualified in such matters. Each hydrogeologic report shall contain:
A. A map showing all sinkholes, depressions, lineaments, faults, outcrops,
springs, drainage entering the ground, water table, soil mottling
and ghost lakes, and all features that may relate to the quality and
availability of groundwater within 200 feet in all directions from
the subject tract.
B. A map outlining all private wells within a radius of 200 feet of
the subject tract and all public water supplies, associated pipes,
hydrants, and future service areas within 200 feet in all directions
of the subject tract provided such information is available from public
sources or documents.
C. A listing of all referenced data, published and otherwise.
D. A topographic site map with the site clearly outlined.
E. A map indicating the location and design of all on site wastewater
disposal systems and secondary systems.
F. A description of anticipated water quality impacts to areas located
downgradient and areas located along the geologic strike.
G. A description of on site mitigation measures that could be applied
to minimize impacts of the project or to correct existing problems.
All applicants proposing the creation of lots which would be served by individual wells or new community water systems shall meet all requirements of Chapter
181, Water.
