8 | Groundwater Sustainability Plan for the Yucaipa Basin Area | San Bernardino Valley Municipal Water District

monitor for potential land subsidence in the groundwater basin. The initial data assessment may or may
not disclose evidence for historical subsidence in the Valley. However, we will prepare a step-by-step
approach to develop a defendable and cost-effective monitoring program for subsidence.

The scale and frequency of the monitoring plan will be formulated to provide a cost-effective means to
evaluate if the on-going water quality conditions are consistent with water quality objectives defined
in the Basin Plan and to track progress towards achieving sustainability goals for the subbasins. As
appropriate, the monitoring plan will include a recommendation to install pressure transducers in several
key wells to allow collection of data between quarterly monitoring events which will allow evaluation
of the interaction of surface water and groundwater seasonal events. The extent of monitoring will
be dependent upon site-specific conditions investigated as a part of this work. The basin conditions
identified by our team will be used to prepare rationale for the scale, location, and frequency proposed
in the monitoring and sampling plan.

Deliverables: TM that will become the “Existing and Planned Monitoring” chapter of the Yucaipa GSP.

TASK 11.0 DEVELOP FRAMEWORK FOR DATA MANAGEMENT SYSTEM
Our team will upload data into your database as directed by the GSA. If a GSP database has not yet been
established as a platform for your SGMA projects, we would recommend considering Earthsoft’s EQuIS
geospatial database used in conjunction with ArcMap GIS. EQuIS is the industry standard for geospatial
water quality and water level electronic data and has a library of standard Electronic Data Delivery
(EDD) formats used to directly upload electronic water quality data and level data without the need
to reformat. EDD standards have been adopted by numerous agencies including EPA Region 9 and the
California Department of Water Resources. This platform is industry standard and can be configured for
web-based access.

Deliverables: TM that will become the “DMS Memorandum” chapter of the Yucaipa GSP.

TASK 12.0 DRAFT AND FINAL GSP
Administrative Draft

The team will prepare a comprehensive Administrative Draft GSP that will incorporate all of the GSP
elements and combine previously reviewed technical memorandums generated at the conclusion of each
task. The Administrative Draft will be provided for review by the Yucaipa Basin GSA.
Draft GSP

The comments from the administrative draft will be addressed and edits will be incorporated in a Draft
GSP document. The Draft GSP will be reviewed by the GSA, local stakeholders, and the general public.
Draft comments will be compiled, organized, and responded to in a comments and responses document.

Final GSP
The Draft GSP comments will be incorporated into a Final GSP document. The Final GSP will be submitted
to the Yucaipa GSP for adoption.

TAC Meetings Deliverables: Prepare draft GSP,
• Administrative Draft GSP– Review Admin Draft and provide respond to comments, and prepare
comments final Yucaipa GSP.
• Draft GSP– Review Draft GSP
