Subject: Letter of Authorization
South Street Pump Station Work
Area II Special Assessment Project
Dear Mr. Dahl:
This Letter of Authorization, if approved, directs WVP to revise the drainage design on South Street
between Edison and Marguerite as follows:
• Revise the storm sewer system to drain to a wet-well near South Street and Marguerite.
• Add a de-watering duplex pump station to the wet-well which will pump through a force
main to the 15" storm sewer on Edison Street.
• Revise plan and profile sheets 26, 31, 32 and 33.
• Add a pump station and force main detail sheet.
• Add a special provision to the project specifications for the pump station and force main.
• Furnish to Elgin five copies of the special provision, five prints of the new and revised plan
sheets, one set of reproducibles of the new and revised plan sheets, plus our opinion of
probable construction cost.
WVP will be compensated for this extra work in accordance with our Agreement dated January 14th,
1991, per THE LA AGREES paragraph 6.
WVP will not exceed $5,000 in fee for this work without the additional approval of the City of Elgin.
Approved: Sincerely,
City of Elgin
WVP CORPORATION

MEMORANDUM
TO: Mayor and Members of the City Council
FROM: Larry L. Rice, City Manager
SUBJECT: Area II Special Assessment Project
Storm Sewer Revisions
PURPOSE: This memorandum will provide the Mayor and Council
with information to consider an extension to the original
engineering contract with WVP Corporation to provide additional
emik services to revise the proposed storm sewer in South Street
between Edison and Marguerite.
BACKGROUND: Presently, any storm water on South Street east of
Edison Avenue generally flows in an easterly direction into the
combination sewer system located at the South/Walnut/Marguerite
intersection. In an attempt to comply with the Illinois
Pollution Control Board and keep or divert as much storm water
as possible from the combination sewer system, a dry well system
was proposed for South Street between Edison and Marguerite to
collect the storm water. The reason for the selection of this
system was because we could not get the water to flow by gravity
west into the storm sewer system to be constructed as part of
the street improvements west of Edison.
The Board of Local Improvements at the Public Hearing on January
8, 1992 determined that they would prefer another alternative
that would discharge the storm water into the storm sewer system
located west of Edison Avenue. An alternate would involve the
installation of a small lift station that would pump the storm
water into the gravity storm sewer system located west of Edison.
We contacted the engineering consultant, WVP Corporation, for a
letter outlining the work that needed to be performed to revise
the plans to include the small lift station and force main, with
the associated cost for the work. A copy of that letter is
attached for your consideration. The provision for authorizing
this additional work is contained in paragraph 6 of The Local
Agency Agrees in the Agreement dated January 14, 1991.

the City Council

FINANCIAL IMPACT: The cost for the engineering services for
this additional work is $5,000 . It is estimated that the cost
of the lift station and force main system will be approximately
$60,000. The entire storm system in this project is being paid
for by the City as a public benefit because all of the storm
water in the improvement area is being removed from the
combination sewer system.
RECOMMENDATION: It is recommended that the City Council approve
the proposed lift station and force main, authorize the City
Manager to execute the letter and direct the staff to prepare
the necessary resolution.
