Series Scope and Content Summary

This series primarily contains project proposals, plans, and reports prepared for the improvement of water service and wastewater management within the SMWD. It also includes information on projects that impacted the SMWD.
The Santa Margarita Water District is divided into eight Improvement Districts. The geographic locations associated with projects and proposals in the collection are identified by Improvement District number, and abbreviated, "ID no." Many of the communities now served by the SMWD had not been built at the time of these records, but were part of the expansive Rancho Mission Viejo. The ID numbers on the materials in this collection roughly correspond with the following regions as they existed in the mid-1970s to early 1980s:
  • Improvement District 1 : Mission Viejo
  • Improvement District 2 : Coto de Caza
  • Improvement District 3 : Northern Rancho Mission Viejo
  • Improvement District 4 : Northwestern Rancho Mission Viejo
  • Improvement District 5 : Southern Rancho Mission Viejo
  • Improvement District 6 : Central Rancho Mission Viejo
  • Improvement District 7 : Southwestern Rancho Mission Viejo
Improvement District 8, located at the northern tip of the SMWD, is not defined in these materials.


Projects that affected several regions are listed first, followed by materials pertaining to specific regions.
