BOOK OF ABSTRACTS
Tuesday, Monday, October 27 23
Concurrent Sessions I 10:00–11:30
Track A: Innovative Storm Water BMPs: A Surf ‘n’ Turf Special
A Cooperative Approach to Innovative Stormwater Management
Todd Shoemaker, Wenck Associates, Inc., tshoemaker@wenck.com; Mike Wyatt, Minnehaha Creek Watershed District
The City of Mound is undergoing a redevelopment of its downtown area which encompasses a large amount of
shoreline on both Lake Minnetonka and Langdon Lake. The Minnehaha Creek Watershed District (MCWD) is
leading a partnership with the City of Mound and developer to reduce the overall amount of nutrient loading
entering Lost Lake, Langdon Lake and ultimately Cooks Bay on Lake Minnetonka. The project includes the
following components:
■■
■■
■■
Identification of partnership opportunities
Engineering and design of improvements
Shared implementation of improvements
MCWD identified this project as a significant opportunity to achieve its long-term loading goals for the area.
The project incorporates innovative stormwater treatment measures (pervious concrete, filtration basins,
pervious pavers, and a biofiltration trench) into the downtown redevelopment to minimize the loading of
nutrients into adjacent waters. The presentation will discuss the project goals, the partnership framework,
treatment measure design, installation pitfalls, and monitoring data.
City of St. Anthony Water Reuse Facility
Todd Hubmer, WSB & Associates, Inc., thubmer@wsbeng.com; Paul Hudalla, WSB & Associates, Inc.
Water reuse projects in Minnesota are a viable means to offset runoff volume and pollutant load increases that
occur due to development. Furthermore, recent studies suggest that projected groundwater demands in the
metro area may be unsustainable. Therefore, water reuse facilities are an important BMP to consider when
planning water resource infrastructure.
This presentation will focus on a case study of the St. Anthony Water Reuse Facility Project. The project
captures stormwater runoff and backwash water from treatment plant filters in an underground storage tank
and uses the water to irrigate a 20-acre park. The facility substantially reduces runoff volumes and pollutant
loads discharged to Mirror Lake and the Mississippi River, and conserves ground water resources of the region.
This presentation will provide information regarding site selection considerations for water reuse projects, as
well as the water budget analysis and design features of the St. Anthony facility.
