El Dorado Irrigation District’s territory extends across the county line to a small piece of Folsom — a total of 190 acres. A developer is planning to turn that acreage into a subdivision. Currently the property is all range land and there is no request for water service. The earliest that water service could be requested may not be until 2023. El Dorado Irrigation District has been a multi-county agency since the early 1980s, according to Jesse Saich, EID communications manager.
