18.39.010 Intent.
The intent of the aquifer protection (AQP) overlay zone district is to identify, classify, and protect vulnerable and/or critical aquifer recharge areas within the city and urban growth area. Protection is to be accomplished by controlling the use and handling of hazardous substances and uses of land that pose a threat to groundwater. This district imposes additional restrictions on development in order to protect public health and safety by preserving the existing and future groundwater supply for the city and urban growth area.
