Stormwater Quality
Ashwaubenon, Wisconsin

Foth designed and imple-mented plans for a regional stormwater detention pond/wetland complex serving the village of Ashwaubenon and two neighboring communities. The developing areas of these communities, including the towns of Lawrence and Hobart would cause increasing drainage and water quality problems if not properly controlled. Additionally, sewer serviceability could not have occurred in these areas without this facility, as mandated by regulatory authority.

Dutchman’s Creek Stormwater Management

The basin drains approximately 2,300 acres of rapidly developing urban lands into Dutchman’s Creek which flows generally in a northeast direction, discharging into the Fox River.

Challenges:

• With complete development downstream, proper stormwater management was critical to the village of Ashwaubenon from environmental, growth, and flood liability standpoints.
• The project needed to improve water quality and prepare the village for upcoming NR 216 requirements.
• Intergovernmental cooperation, including water-shed area assessments was critical between three separate communities.
• This project included the first major Environmental Sensitive Area (ESA) amendment request presented to Brown County Planning.

Benefits:

• Peak flows controlled to desirable levels.
• Able to develop over three square miles of land in these communities.
• Present and future development protected through control of floodwaters, delineation and confinement of specific floodplain areas, and enforcement of associated floodplain regulations and other local ordinances.
• Stormwater quality for this area improved to meet new regulations through a combination of water quality enhancement features in the detention pond/wetland complex.
• Recreation opportunities created with the addition of over four miles of bike/pedestrian pathway along the regional pond and stream corridor.
• Funding assistance provided through a non-point source Water Quality Grant.
