Schuppert Mark -- Grossmont Mt. Helix Improvement Association (GMIA)
The Grossmont - Mt. Helix Improvement Association (GMIA) is one of the oldest and largest associations of its type in San Diego County. It was formed in 1938 as a result of community concern for the lack of adequate land use (planning and zoning) type requirements. It is a non-profit corporation to benefit the community that represents thousands of families residing in the large unincorporated area of the County. The boundaries extend from east of Bancroft Drive, south of El Cajon, generally north of SR94 and Rancho San Diego, and west of SR54/Jamacha Rd. The GMIA area contains over 7,000 single-family residences with a population approximating 20,000 people.
