ISSUE
The City of Rosemount developed a Stormwater Management Plan in August 2007 to meet local
watershed management planning requirements of the Metropolitan Surface Water Management Act and
Board of Water and Soil Resources Rules 8410. It was also developed to be in compliance with the
requirements of the local Watershed District and Watershed Management Organizations, Metropolitan
Council requirements and applicable State and Federal Laws. Wachter is a stormwater collection pond for
th
the drainage area west of Robert Trail, roughly south of 140 St W and north of Chippendale Ave W.
BACKGROUND
Wachter Pond currently does not have an outlet for stormwater. It has an 8-foot “bounce” in typical water
to the high water elevation. With the recent wet weather over the past couple of years, the water elevations
in Wachter (along with most other stormwater ponds in Rosemount, have risen, sometimes dramatically.
The stormwater ponds are operating in the manner they were designed and expected to, from an
operational perspective. However, from a resident perspective, the pond water levels are rising and
creating dead growth, added, wet areas, increased trash, etc.
Many residents view and use our larger stormwater ponds as an amenity and have higher level of
expectations for maintenance. As staff continues to review the stormwater program, we are working with
residents to define the intent, use and maintenance of stormwater ponds, along with identifying
opportunities to partner and develop ways to both continue effectively maintaining stormwater functions
while providing residents means to provide their own higher level of maintenance as an amenity.
Staff has met with residents along Wachter Pond and have partnered on some cleanup activities. We
continue to have dialog on how to develop and enhance procedures as a “trial” project partnering with
residents and hope to utilize this process on additional stormwater ponds and facilities in the future.
