§ 22.52.140. Groundwater Recharge.

A.

Requirements. Groundwater recharge elements must be included in the project design to mitigate the impacts on recharge caused by the reduction in the permeability of soil areas on the site, except when any of the following site characteristics exist:

1.

High groundwater in the area limits the effectiveness of recharge efforts or enhancing groundwater recharge would create additional problems related to high groundwater.

2.

The entire site being developed is shown to contain impervious soils that would not benefit from recharge efforts.

3.

There is a known geologic instability that would be negatively impacted by increased groundwater recharge.

4.

It can be demonstrated that no additional runoff will occur from the development.

5.

Federal or state regulations prohibit recharge.

B.

Groundwater recharge. All areas on the project site that will become impervious or will have their soil permeability impaired (such as compaction of soil under an all weather driveway) must be mitigated to the maximum extent practicable with recharge enhancement elsewhere on the parcel. Offsite mitigation is a secondary alternative
