jonathan.daly@ci.corona.ca.us A specific effort was successful development of an application to DWR
to modify the boundaries of the Temescal Basin and adjoining Elsinore
Key Todd Staff:
Basin; this was a collaborative effort by the City, Elsinore Valley
Phyllis Stanin, Chad Taylor, and Iris Municipal Water District (EVMWD), and Temescal Valley Water District
Priestaf (TVWD). The modification involved delineation of the southern
Temescal boundary, partition of the northernmost Elsinore Basin—
creating a new Bedford‐Coldwater Basin—and improved alignment of basin boundaries with alluvium.
Justification of the boundary changes was based on scientific evidence and explanation of how the modifications
would enhance local management. Todd Groundwater organized and synthesized substantial information and
assisted with submittal of the application, which was approved by DWR.
The City of Corona, City of Norco, and Home Gardens County Water District have formed a GSA for the Temescal
Basin and are coordinating to prepare a GSP before 2022. Todd Groundwater assisted the Temescal GSA with
preparation of a successful Sustainable Groundwater Planning grant application. Todd Groundwater also has
assisted in tracking and reviewing SGMA activities in adjacent groundwater basins that potentially could affect
the City. This has included analysis of suggested basin boundary revisions and review of an Alternative Plan
(prepared by Orange County Water District).
Phyllis Stanin is the Project Manager leading the project; Chad Tayler is the Project Hydrogeologist mapping GSA
boundaries, describing the managed area, and identifying stakeholder; and Iris Priestaf is providing overall
technical review.
