17.10.120 Critical aquifer recharge areas – Identification.
A. Critical Aquifer Recharge Areas (CARAs) Designation. CARAs are those areas with a critical recharging effect on aquifers used for potable water as defined by WAC 365-190-030(3). CARAs have prevailing geologic conditions associated with infiltration rates that create a high potential for contamination of ground water resources or contribute significantly to the replenishment of ground water. In the city of Lynnwood and vicinity, these areas include the following:
1. Wellhead Protection Areas. Wellhead protection areas may be defined by the boundaries of the 10-year time of ground water travel or boundaries established using alternate criteria approved by the Washington State Department of Health in those settings where ground water time of travel is not a reasonable delineation criterion, in accordance with WAC 246-290-135.
2. Susceptible Ground Water Management Areas. Susceptible ground water management areas are areas that have been designated as moderately or highly vulnerable or susceptible in an adopted ground water management program developed pursuant to Chapter 173-100 WAC.
B. Mapping of CARAs. The approximate location and extent of critical aquifer recharge areas are shown on the city critical areas inventory map for CARAs. (Ord. 3193 § 2, 2016)
