The public is invited to comment on new state subsidence guidelines at three workshops next week. The Department of Water Resources is holding meetings on Sept. 9 in Clovis, Sept. 10 in Delano and Sept. 11 in Willows. The workshops are focused solely on collecting feedback on a recently released draft document that supports one of the goals of the Sustainable Groundwater Management Act — avoiding or minimizing subsidence, land sinking. The document outlines fundamental concepts of subsidence and explains what practices local groundwater agencies should use in their groundwater sustainability plans to halt or minimize subsidence.
