Dear Mr. Samara,
Maddaus Water Management Inc. (MWM) is pleased to present this outline of a phased proposal to provide
technical services for the City of El Segundo (City) to develop a revised Water Supply Assessment (WSA).
Considering MWM's previous experience with West Basin Water District's water data and demand forecasts,
along with our extensive experience developing WSAs, Urban Water Management Plans, and Water Supply
Master Plans, we are confident we can provide cost-efficient and high -quality support forthe development of
the City's WSA. This letterproposal presents MWM's understandingof the City's needs alongwith an outline of
anticipated tasks in each phase, schedule and estimated fees.
IINT1° OD1,IC-1 10 T
The City is in the process of developinga Downtown Specific Plan (DSP). The current DSP was adopted in 2000
with a 10-yearvision. 20 years have passed, and theCity is lookingto confirm and enhance the vision. The project
would revise the existing DSP planning districts, amend General Plan and zoning designations on eight parcels,
and include mobility enhancements. The project would also include public improvements and streetscape
guidelines, private urban form criteria, permitted land uses, development standards, mobility and infrastructure
improvements, an implementation plan, and administration processes. MWM understands that per Water Code
Section 10910 the City must prepare a Water Supply Assessment (WSA)forthe DSP. MWM proposes to support
the City with the development of a WSA using a phased approach presented in the outline below. It is MWM's
preference to prepare a Scope of Work prior to the initiation of each phase to ensure that MWM and the City
have confirmed all expected deliverables, are aware of which tasks will be the most resource intensive, and that
any requests or changes resulting from the prior phase is incorporated moving forward. The first 4 Phases were
completed before the commencement of this WSA revision project.

To calculate the demand estimates for the Smoky Hollow development, MWM will determine the net increase
in demand compared to the demand associated with existing developmentthat was already included in the EIR.
MWM will utilize the unit water use for the projected building uses using City data supplied in Phase 1, as well
as referencing our more than 20 years of experience conducting audits of commercial buildings throughoutthe
United States.

format.
Td sk 2 ...... Sijr)ply vim Demand Comparison Revision

City's recentAmerican Water Works Association Water Loss Audits and will evaluate demand reduction due to
passive and active conservation.

MWM with track changes. MWM will revise the WSA one time, based on the comments received from the City,
and provide the Citywith a Final report. If the proposed development project parameters change (i.e., the square
footage orthe specified use of buildingspace changes) in a mannerthat requires revision tothe WSA, additional
scope and budget would be needed for MWM to revise the WSA. The WSA that needs revision is 27 pages in
length and will only be updated in the text and tables that are changed due to the Smoky Hollow project update.
