RE: Award of Engineering Services Agreement—
Design Services for the City Hall Area Storm Water Detention Basin
AECOM Technical Services (AECOM)
In July 2009, an engineering services contract was awarded to AECOM to perform detailed
planning-level analyses of storm water watersheds in conjunction with the 2010 Capital
Improvements Program. The Division Street Watershed was included in this analysis, as several
streets in the upper reaches of the watershed were scheduled for reconstruction.
The analysis of the Division Street Watershed showed several areas where flooding was a concern
in existing conditions. Several alternatives were analyzed to reduce the impacts of the flooding in
those areas. The components of the alternatives analyzed included: upgrades to existing storm
sewers; installation of new storm sewer systems; diversion of runoff into adjacent watersheds;
detention basins; an underground detention system; and combinations of the aforementioned
components. The recommended alternative included a combination of storm sewer upgrades, new
storm sewer systems, the diversion of a small portion of the upper portion of the watershed into an
adjacent watershed, and an underground detention system on the City Hall/Safety Building property.
Due to their familiarity with the Division Street Watershed, the Department of Public Works
requested a proposal from AECOM for design-related services for the City Hall Area Storm Water
Detention Basin. The services included in this contract include preparing plans and specifications
for the bidding of the underground detention system, the storm sewer from the detention system to
the Fox River, and the City Hall and Safety Building Parking Lot design. The services also include
environmental review, sampling and coordination with Wisconsin Department of Natural Resources
for disposal of anticipated impacted soils and sediment.
The cost of these services is estimated not to exceed $250,682. Funding for these services is
available in the Storm Water Utility budget and the Property Improvements budget of the Capital
Improvements Program.
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a
specialized nature, including engineering services, may be procured without the use of formal,
sealed quotes. I have reviewed the AECOM proposal and in accordance with Section 12-16 of the
Code, I am hereby recommending that the Common Council approve the award of this engineering
services agreement.
