Dear Mr. Jones:
On behalf of the Dudek team that you and the Yucaipa Groundwater Sustainability Agency (GSA) met during our
interview on August 9, 2018, I’d like to express our sincere gratitude in the GSA selecting Dudek to develop the
Groundwater Sustainability Plan (GSP) for the Yucaipa Basin. Per the request of the Yucaipa GSA, we have revised
our scope of work and project assumptions to streamline the GSP development process at a reduced cost, but
still provide a plan that will be compliant with the regulatory requirements of the Department of Water Resources
and beneficial for all users in the basin. The following bullet items summarize the modifications made to our
original scope of work and fee:

• The project timeline for preparing a draft GSP for public review was reduced from 36 months to 28
months. Consequently, this reduced the cost in project management by $34,000 with a reduction in the
number of meetings with the GSA from 36 to 8, monthly progress reports, and weekly update phone
calls. Dudek will allocate two (2) hours per week for the update phone calls and additional
communication, and six (6) hours per month to prepare progress reports and invoices.

• We have reduced the number of labor hours for the project by 32% after removing four personnel (a
$155,000 savings in cost) and redistributing fewer hours to more experienced staff. The overall
reduction in labor cost is $366,000. The following items provide more detail in how Dudek reduced the
labor cost.

o The original scope of work identified thirteen (13) Technical Advisory Committee (TAC) meetings
that Dudek personnel would participate in at a cost of $132,000. The revised scope identifies
eight (8) meetings with the GSA, four (4) meetings with the TAC, and two (2) public meetings. The
project manager, Mr. Stuart, will attend these meetings and be accompanied by Dr. Weinberger
or other staff pertinent to the specific meeting topic at that time. The revised fee for Dudek to
participate in these meetings is $120,000.

o Per the GSA Board, the task to establish the Governance of the GSA was removed and the cost
allocated to infiltration testing was reduced by 90%, resulting in a cut of $35,500 from the
original budget with these two modifications. Dudek understands that Todd Groundwater will
perform the infiltration testing and analysis. Dudek anticipates receiving the results from Todd
Groundwater and SBVMWD and will incorporate the findings into the GSP and, if applicable, the
numerical model to evaluate the potential impacts of implementing additional artificial recharge
in the basin.
