Watershed Existing Conditions StudyCreeks

In 2004, Questa Engineering was hired to prepare a Watershed Existing Conditions Technical Study for the Arroyo Burro, Mission and Sycamore Creek watersheds. 

The purpose of the existing conditions study is to integrate information on watershed characteristics such as natural resources, creek hydrology, water quality, cultural resources, urban infrastructure management, land use, and jurisdictional policies. The study also analyzes how historical activities, including land development, have contributed to current conditions, and identifies any critical information gaps.

The study was expanded in 2005 to include the Laguna Watershed.
