A 400-acre strip of land commonly referred to as the “Locke Ranch” area intersects the District. The “Locke Ranch” area consists of mostly residential dwellings with commercial centers at Yorba Linda and Fairmont Boulevards, and on Esperanza Road at Fairlynn Avenue. The area was originally outside of the District’s boundaries, but now lies in the middle of the District’s service area. The Golden State Water Company serves water to residents of this area, while the District owns and maintains the sewer system.
