17.140.010 Establishment of drinking water source protection zones.
There are hereby established use districts to be known as zones one, two, three, and four of the drinking water source protection area, or alternatively the management area. These zones shall have the approval of the state of Utah, Division of Drinking Water, as described in R309-600, Source Protection: Drinking Water Source Protection for Ground Water Sources, and are identified and described as follows:
A. Zone one is the area within a 100-foot radius from a wellhead or margin of the collection area.
B. Zone two is the area within a 250-day ground water time of travel to a wellhead, the boundary of the aquifer(s) which supplies water to the ground water source, or the ground water divide, whichever is closer, as specified on the “Drinking Water Source Protection Zone Map” on file with the city.
C. Zone three (waiver criteria zone) is the area within a three-year ground water time of travel to a wellhead or margin of the collection area, the boundary of the aquifer(s) which supplies water to the ground water source, or the ground water divide, whichever is closer, as specified on the “Drinking Water Source Protection Zone Map” on file with the city.
D. Zone four is the area within a 15-year ground water time of travel to a wellhead, the boundary of the aquifer(s) which supplies water to the ground water source, or the ground water divide, whichever is closer, as specified on the “Drinking Water Source Protection Zone Map” on file with the city. In some cases, such as bedrock areas, zones two, three, and four are overlapping, due to the inability to determine time of travel. These are sensitive areas. In these cases, the zone should be protected as for zone two.
E. “Management area” means the area outside of zone one and within a two-mile radius where the optional two-mile radius delineation procedure has been used to identify a protection area, as described in the Utah Division of Drinking Water R309-600, Source Protection: Drinking Water Source Protection for Ground Water Sources. This area shall be treated as for zone two. [Ord. 08-17-2021B § 2 (Exh. A)].
