SUBJECT: ENGINEERING SERVICES PROPOSAL REGARDING RIVERSIDE
DRIVE LIFT STATION RELOCATION
Dear Mr. Papagolos:
As you are aware, Engineering Resources of Southern California, Inc. (ERSQ is currently
a member of a consulting team designing the widening Riverside Drive, also State Highway
74, in conjunction with and adjacent to the La Laguna RV Resort. In the area of widening,
there exists a lift station designated A-4 by the current owner, Elsinore Valley Municipal
Water District (District). The lift station was constructed for the City as Pump Station No. 3
in 1970. Wastewater delivered by three sewers is collected in the pump station wet well and
discharged to a 10 -inch force main constructed in 1997, by the District. The lift station
includes a prefab duplex pump chamber wet well, electrical service, motor control center, and
standby generator. Existing pump station base is approximately 27 feet below the surface.
Prospective project, then, involves the design of a replacement lift station to the southeast
into the La Laguna RV Resort. Issues to be considered are that of the depth of the pump
station, force main and sewer, possible dewatering required during construction, odor from
wet well vents, and adequate maintenance access.
PROPOSED ENGINEERING SERVICES
Services required and proposed to be conducted will involve civil, mechanical, and electrical
design for preparation of plans, specifications, and estimates for a replacement lift station. It
is anticipated these will need to be conducted to current standards of the District. District
representative indicates that standard design now is for construction of a single/combined
pump chamber/wet well, different from the existing dry pump chamber/wet well. Basis of our
proposed design and PS&E preparation effort will be the District's standard and that capacity
of the replacement lift station will be the same as the existing facility.
Proposed tasks to be performed include the following:

Conduct research and consult with the City and the District regarding current
design standards and requirements for lift station design.
2. Research the design and sizing of the existing lift station and verify design
criteria applicable for the new lift station.
3. Select a suitable site for the replacement lift station, anticipated to be within
the Park and potentially at the site of the existing Boat Launch Lift Station.
Effort will include consultation and involvement of both the City and the
District.
4. Obtain elevation of the existing sewer invert in Riverside Drive by a sub
consultant.
5. Coordinate conduct of a geotechnical investigation by a sub consultant
retained by the City.
6. Review opportunities for the collection of Park wastewater, from existing
sewered area(s) and proposed; finalize station capacity and sizing of pumps,
motor, and generator.
7. Coordinate with architect's sub consultant regarding electrical service design
for the replacement lift station.
8. Prepare plans, specifications, and estimates that is PS&E for the civil and
mechanical features including the lift station and appurtenant facilities, gravity
sewer and force mains.
9. Submittals will be made to the appropriate agencies, either the District and/or
the City, at preliminary concept and at the 30%, 50%, 90%, and 100%
completion stages; final submittals will be made of stamped and signed plans
and specifications for City and District approval.
PROJECTPERSONNEL
Oversight and coordination with the City concerning the design effort will be the
responsibility of Matt Brudin, P.E. who holds a similar position concerning ERSC' efforts
for the La Laguna project.

Project Manager for the design effort will be Mr. John Egan, P.E. In his many years of
experience, Mr. Egan has been responsible for design and/or modifications of numerous lift
stations for Crestline Sanitation District and the County of San Bernardino.
Mr. Ron Worthington, P.E., will provide oversight of the design as well as quality
assurance/quality control reviews and detailed review of pians and specifications.
Electrical design, as indicated, will be conducted by the firnn. of T -Squared Engineering of
Vista, the current electrical consultant for the La Laguna project. Specifically responsible for
the electrical design is Mr. Farzad Tadayon, P.E., of the firm.
Geotechnical investigation will be the responsibility of Inland Foundation Engineering
through the City.
PROPOSED ENGINEERING FEE
ERSC will complete the design services for the replacement lift station as described for a
lump sum amount of $42,340. Derivation of the fee amount is shown on the accompanying
spreadsheet.
We appreciate the opportunity of submitting our proposal and engineering qualifications to
the City for the replacement lift station project. Should there be any questions, please contact
the undersigned.
Respectfull Submitted,
