guidance and discussions with DWR, we note that GSPs will be evaluated by hydrogeologists such as
ourselves and must provide the depth of knowledge necessary to stand up to a rigorous technical
assessment.
The GSP is considered the foundation of SGMA compliance and demonstrates sustainable management
for the Subbasin. Our approach for the Yucaipa GSP incorporates the following:

 complies with GSP regulations, incorporating BMPs
 makes best use of existing data
 establishes meaningful sustainability criteria for the YGSA
 coordinates with GSAs in adjacent basins, and
 provides transparency through public outreach/communication with local stakeholders.

The intent of this GSP is effective and adaptive local management, which is allowed by the GSP
regulations to satisfy local values and needs. Accordingly, our approach will be to develop a GSP that
meets GSA needs first, complies with GSP regulations, moves forward with a level of detail
commensurate with available data and basin issues, and considers a long‐term view of adaptive
management. For such a GSP, our team combines local knowledge, working experience with SGMA, and
strong technical expertise.
Assembling the technical information for the GSP is relatively straightforward, but obtaining stakeholder
buy‐in on the GSP can be a challenge. As noted above, we plan to work with stakeholders early and often
to develop a common understanding of basin conditions, define sustainability criteria, and discuss
options. We also recognize that common ground has already been established through your previous
groundwater studies and planning efforts, and that there is a shared resolve to move forward with
projects and management actions. Accordingly, identifying and implementing cost‐effective projects and
management actions that meet local sustainable criteria is a key part of the GSP. In compliance with the
regulations, analyses must demonstrate how these projects achieve and maintain sustainability,
requiring groundwater modeling tools. Based on our experience working in the Basin and elsewhere, we
offer both the expertise and tools to evaluate specific potential projects and management actions (e.g.,
recharge of imported water and stormwater capture in in‐channel and off‐channel locations across the
Basin) for consideration by the YGSA and stakeholders and incorporation into the GSP.

The proposed scope of work to develop the Yucaipa GSP has been divided into eleven (11) tasks, details
of which are presented below. The proposed scope of work covers the tasks identified in the Scope of
Services in the Request for Proposal. It is organized in the same sequence as shown in GSP Work Plan
submitted as part of the GSP grant application with slight modifications to ensure adherence to GSP
regulations. It is noted that at the completion of Tasks 2 through 5, the respective draft chapter of the
GSP will be prepared and submitted to the YGSA for review to solicit comments and encourage early
discussion of key findings and recommendations. Additionally, fact sheets and website postings will be
prepared to support public outreach efforts.

Task 1 – Collect Data and Develop GSP Databases

This task includes the collection, review, and preparation of GSP hydrogeologic datasets and documents
that will be used to develop required components of the hydrogeologic conceptual model (Task 2) and
support preparation of the public outreach plan (Task 8).
