SYNOPSIS:
Approval
of Supplemental Agreement No. 6 to the Professional Services Agreement with

West Des Moines, Iowa 50266-1322, for a cost plus fixed fee not to exceed $233,385.86, to provide additional construction
phase services for the I-235 Ingersoll Run Outlet Storm Sewer Phase 2.
This is a Joint City and Iowa Department of Transportation
(IDOT) project. The IDOT has
approved this Supplemental Agreement and its funding.
FISCAL IMPACT:
Amount: $233,385.86
Funding
Source: $128,362.22 – City
of Des Moines portion from the 2009-2010 CIP, Page Street Improvements-20,
I-235 Storm and Sanitary Sewer Improvements, STR197 (Loan payment to the Iowa
Department of Transportation was made in 2008, future payments are anticipated
in 2010, and 2011); and $105,023.64 from the Iowa Department of Transportation.
ADDITIONAL INFORMATION:
On August 31, 2000, by Roll Call
00-3634, the City Council approved a pre-design agreement (Agreement No.
2001-P-028) with Iowa Department of Transportation (IDOT) for Interstate 235
(I-235) from the west city limits to the north city limits. The pre-design agreement with IDOT identified
three storm sewer outlet projects that the City and IDOT are jointly
responsible for, including sharing of funding responsibilities. The three projects are identified as Birds
Run, Deans Lake, and Ingersoll Run Outlet storm sewers.
This supplement will be the sixth
supplement to the Birds Run Professional Services Agreement. The original agreement and Supplemental
Agreements 1, 3 and 4 were for Birds Run storm design, sanitary design, and
construction phase services. Supplemental
Agreements 2 and 5 were for the Ingersoll Run design and construction phase
services. The total cost, including the
proposed supplemental agreement, is not to exceed $2,694,368.08. The total construction cost for the Birds Run
and Ingersoll Run projects is estimated at approximately $20 million.
The I-235
Ingersoll Run Outlet Storm Sewer – Phase 2 project is located along High Street
from 22nd Street and High Street to 34th Street and Woodland
Avenue. This project will separate I-235
storm water, Des Moines storm water and Des Moines sanitary flows into two
separate systems. Currently
storm water runoff from the I-235 interchange at 31st Street drains
into the combined sewer between Ingersoll Avenue and High street along with
storm runoff from a considerable area of Des Moines and also sanitary sewer
flow from this area.
These improvements are necessary
as part of a program to meet Iowa Department of Natural Resources (IDNR)
requirements for combined sewer overflow (CSO) abatement and storm and sanitary
separation through implementation of a long-term control plan which will reduce
localized sanitary sewer backups. The
City of Des Moines is also taking this opportunity to construct additional
capacity in the I-235 Ingersoll Run Outlet Storm Sewer, which will become the
backbone of the storm sewer system needed to separate the Ingersoll combined
sewer in the future as well as help to address the chronic flooding problems in
the Ingersoll Run Subsystem. Future
combined sewer separation projects will be driven by implementation of the long-term
control plan approved by the IDNR and should provide additional flooding relief
within the Ingersoll Run Subsystem.
In 2001, staff recommended
selection of Veenstra & Kimm, Inc. after evaluating submittals for the
design work from nine consulting firms. The
submittals were rated independently by five staff members and approved by IDOT. Veenstra & Kimm, Inc. designed the
Ingersoll Run Storm Sewer project from 22nd and High Street to 34th
and Woodland Avenue; and therefore was selected to perform the construction
administration and inspection.
Staff has negotiated a
Professional Services Supplemental Agreement with Veenstra and Kimm Inc., for a cost plus fixed fee not to exceed
$233,385.86, to provide additional construction phase services for the I-235
Ingersoll Run Outlet Storm Sewer Phase 2.
The IDOT has reviewed and approved
Supplemental Agreement No. 6.
