Maddaus Water Management Inc. completed a Los Osos Water Offset Study in June 2023 to evaluate the "retrofit-to-build" program and inform ongoing land use and water resources planning efforts for the community. The study includes updated estimates of average annual residential water use in Los Osos; an estimate of remaining water savings potential, considering historic conservation measures and remaining indoor and outdoor water efficiency retrofits; and recommendations for increasing program reliability. The Department may recommend amendments to the retrofit-to-build program policies based on the study findings, which would be subject to approval by the County Board of Supervisors at a public hearing.
