Memorandum
Date: June 4, 2014
To: HCP Team
Cc: Bob Tincher, San Bernardino Valley Municipal Water District
From: Lucas Bare, Scott Fleury, Mike Romich; ICF International
Subject: Revised Proposed Plan Area for the Upper SAR HCP
During Phase 1 of the Upper Santa Ana River Habitat Conservation Plan (Upper SAR HCP or Plan),
the HCP Team identified a proposed Plan Area. The Plan Area is based on several criteria, as
described in the Phase 1 Report, including where HCP Team water resource agencies currently
operate and anticipate constructing and infrastructure in the future and areas where HCP
conservation activities may occur.
Since the proposed Plan Area was identified, Western Municipal Water District of Riverside County
(Western) noted areas within its Retail Service Area but outside the previous draft Plan Area where
it would be conducting activities that could potentially be covered by the Plan. Therefore, the
proposed Plan Area was revised to include this new area. This memo describes the revised Plan
Area.
Description of the Revised Plan Area The methods used to define the Plan Area boundary described in the Phase 1 report, including
overlay of Geographic Information System (GIS) layers including HCP Team water resource agency
service area boundaries, jurisdictional or land use boundaries, and USGS level 12 sub-watersheds.
Figure 1 shows the revised proposed Plan Area. The revised Plan Area boundary continues
southeast from Prado Dam along the San Bernardino-Orange County line as it crosses Highway 91. It
follows this county boundary generally along the crest of the Santa Ana Mountains until
approximately 5 miles north of Ortega Highway (SR 74), where the Plan Area boundary turns
eastward along the Santa Ana River watershed southern boundary. The Plan Area boundary
continues east and then north along this watershed boundary except in two instances where
Western’s boundary extends east of the watershed. The Plan Area corresponds to Western’s

boundary in these instances, until it rejoins the previous draft proposed Plan Area boundary, as
described in the Phase 1 Report.
The revised Plan Area includes all or a portion of the following USGS HUC level 12 sub-watersheds
plus all of the area covered by the previous draft Plan Area included in the Phase 1 Report:
Lake Norconian-Temescal Wash
Main Street Wash-Temescal Wash
Bedford Wash-Temescal Wash
Dawson Canyon-Temescal Wash
Arroyo Del Torro-Temescal Wash
Railroad Canyon Reservoir-San Jacinto River
Perris Reservoir
Lake Matthews
Hole Lake
As described in the Phase 1 Report, portions of the Plan Area still may be adjusted throughout the
development of the Upper SAR HCP, as other Plan elements are completed, including further
refinement of the descriptions of the covered activities and covered species.
