A. General. Aquifer recharge areas are areas where the prevailing geologic conditions allow infiltration rates which create a high potential for contamination of ground water resources or contribute to the replenishment of ground water.

B. Classification. For the purposes of this chapter, the boundaries of the City’s aquifer recharge areas are:

1. The boundaries of the two highest DRASTIC zones which are rated 180 and above on the DRASTIC index range, as identified in Map of Ground Water Pollution Potential, Pierce County, Washington, National Water Well Association, U.S. Environmental Protection Agency; and

2. The Clover/Chambers Creek Aquifer Basin boundary, as identified in Draft Clover/Chambers Creek Basin Ground Water Management Program and Environmental Impact Statement, Brown and Caldwell for Washington State Department of Ecology.

3. Any site located within the Clover/Chambers Creek Basin boundary or the two highest DRASTIC zone boundaries is included in the aquifer recharge area. [Ord. 362 § 3, 2004.]
