Lone % Based on this analysis, recommendations have been developed to refine the methodology used in the next regional update project to further improve the next iteration of the regulatory plan. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above.
