Reference: Huset Park Stormwater Management and Harvesting System Preliminary Report
Dear Kevin,
In our September 18, 2018 meeting, you indicated that the City of Columbia Heights would like to plan for
potential irrigation improvements to one or two of the fields in Huset Park, using water from the existing
Zurek Pond. In subsequent discussions with you and with Doug Snyder, it was indicated that the
Mississippi Watershed Management Organization (MWMO) would have an interest in building on this
project to improve water quality as well as reduce flooding issues downstream in Minneapolis.
As a first step, the City needs to determine the feasibility and desirability of this project. Staniec proposes
to assist the City in this effort by preparing a preliminary report that evaluates stormwater management
options, provides an initial recommended design concept, and estimates the cost of this potential project.
Options to be evaluated include:
•Pumping from Zurek Pond to irrigate the fields
•Providing a pond outlet that could draw down the Zurek Pond level, thereby increasing the effective
flood storage. It is our understanding that expanding the pond size is not an option, due to space
constraints within the park.
•Providing additional pond storage in Huset Park at a location other than Zurek Pond
•Providing a filtration bench along the pond, enhanced with iron filings to remove dissolved
phosphorus, and potentially including a recirculating pump in a pump station
The tasks to prepare this preliminary report will include:
1.Stormwater Modeling. Stantec will build on the MWMO's XPSWMM model of the area to create a
model of the drainage area, including Huset Park and Zurek Pond, to a downstream outlet point at
5th Street NE and Columbia Way in Minneapolis. The model will be used to estimate existing
flooding conditions in the residential area northeast of the 5th StreeUColumbia Way intersection as
well as various flood control options.
The primary flood control options include drawdown within Zurek Pond and additional flood storage
within Huset Park. Staniec will use the XPSWMM model to evaluate the effectiveness at reducing
flooding in the downstream residential area in Minneapolis. Drawdown in Zurek Pond will assume
Design with community in mind
