A bitterly contested commercial solar project in the California desert was unanimously approved by the Riverside County Board of Supervisors on Tuesday after what one official described as a “doozy” of a public hearing in which retirees begged the board to consider an “environmentally superior” alternative further from their homes. … [S]easonal and full-time residents at Lake Tamarisk vigorously contested the company’s claims and said they remain concerned about heavy construction dust, impacts on a groundwater aquifer and steep declines in property values due to lost scenic views. … Intersect Power’s Senior Director of Environmental and Permitting Camille Wasinger defended the project vigorously during the hearing and pushed back against residents’ concerns, saying more aggressive dust suppression measures would be employed than had been used at Oberon, an earlier large project they built near area homes, and that an expert’s study had shown it would use little water and have no groundwater impact.
