November 25, 2018 (San Diego’s East County) -- The new owner of Cottonwood Golf Club wants to turn the site into a sand mine along the Sweetwater River in Jamacha Valley over the next 10 years.  If approved, the project in the Rancho San Diego area of unincorporated El Cajon would mine an estimated 5.8 million tons of sand from 198 acres of the 280-acre site.
