Considering critical aquifer recharge areas when revising an urban growth area.

HB 2358 requires counties to consider critical aquifer recharge areas (areas that replenish groundwater) when revising urban growth areas (UGAs), which are designated zones for future development. This directly affects counties and cities with UGAs needing boundary revisions under Washington's growth management laws. The key provision mandates that any expansion of UGAs must avoid encroaching on critical aquifer recharge zones, protecting groundwater sources from development pressure. Counties must ensure revisions comply with this requirement during their scheduled plan reviews.
