Horizontal/Vertical Control Networks

In 1995, city surveyors, the custodians of survey monuments, filed Record of Survey (RoS) 14841 that officially established the foundation for the city's Survey Control Network. This network was critical for the creation of basemap layers planned for the city's new GIS program. It was particularly important because the city was entering an era of significant growth at the same time.

Subsequent to RoS 14841, a subdivision manual was written that incorporated the standards for the city's Survey Control Network. In conjunction with the subdivision manual, the city of Chula Vista's municipal code requires that development perpetuate and extend the city's horizontal-vertical control to a one-half-mile and one-quarter-mile density, respectively.

The horizontal control is First Order-C category and the vertical control is Third Order. In partnership with GIS staff, city survey staff designed a Microsoft Access database to create event themes that depict the current network on existing and planned development. This six-month effort was subsequently used to inform developers of their fair share contribution to the network. The long-term goal of this endeavor will be to make this information available to the public via the city's Internet site. This map is intended to depict the relationship of survey monuments to current and future residential growth in eastern Chula Vista.
