RE: Approve Professional Services Agreement with Strand Associates, Inc.
(Strand) for Engineering Design Services for Sawyer Creek Rural II
Detention Basin ($495,000)
BACKGROUND
The City of Oshkosh was awarded a construction grant from the Wisconsin Department
of Natural Resources (WDNR) Municipal Flood Control Grant Program for the
construction of the Sawyer Creek Watershed Rural II Detention Basin. The
approximately 55-acre dry detention basin will have the ability to store approximately
300 – 400 acre-feet (approximately 114 million gallons) of storm water and will be
constructed similar to the James Road Detention Basin.
The Department of Public Works requested a proposal from Strand for assistance with
engineering design services for the Sawyer Creek Rural II Detention Basin. The services
to be provided will include collecting survey information necessary for design drawings;
modifying the Federal Emergency Management Agency (FEMA) effective hydrologic
and hydraulic models in accordance with FEMA and the WDNR Guidelines to review
the floodplain area under multiple conditions; providing floodway delineation of the
City-selected condition; providing a basin failure analysis for the Project basin;
communicating with the WDNR regarding breach geometry and criteria to use in the
basin failure analysis model; preparing a Hydraulic, Hydrologic, and Stability Analysis
Report in accordance with WDNR regulations; preparing a storm water management
plan for the 80-acre fill site located south of the Project basin; preparing bidding
documents for the Project; preparing Opinion of Probable Construction Costs (OPCC)
based on sixty percent (60%) drawing and updating the OPCC based on final Project
drawings; providing assistance during bidding; providing permitting assistance; and
providing Plans and Specifications, AutoCAD files of Project survey and design, ESRI
ArcGIS files created or updated for the Project, and model files generated for the Project.

ANALYSIS
Strand was chosen for these services due to their staff familiarity with the City of
Oshkosh, the Sawyer Creek Watershed, and previous work within this watershed.
FISCAL IMPACT
The cost of these services is estimated not to exceed $495,000. The cost for these services
was included in the Storm Water section of the 2022 Capital Improvements Program
(Account #03210410-6804-04115/Contract Control-Storm Sewer-21-15 Sawyer Creek
Watershed Detent).
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh (Code) provides that professional
services of a specialized nature, including engineering services, may be procured without
the use of formal, sealed quotes. I have reviewed this agreement and in accordance with
Section 12-16 of the Code, I am hereby recommending that the Common Council approve
the award of this professional services agreement.
Approved,
Mark A. Rohloff
City Manager
