Minnewashta Manor Wetland Maintenance and Restoration -SWMP18D6
Approve Quote
PROPOSED MOTION
"The City Council approves a quote for the Minnewashta Manor Wetland Maintenance and
Restoration from Widmer Construction in the amount of $43,278.25.''
City Council approval requires a simple majority vote of the City Council present.
BACKGROUND
The wetland proposed for maintenance has had significant amounts of sediment accumulation
from stormwater runoff over the past 46 years. This particular basin receives almost all the
stormwater for the Minnewashta Manor neighborhood prior to its discharge into Lake
Minnewashta. Maintenance of this basin is critical to prevent significant pollution from entering
the lake and for flood control.
DISCUSSION
Stormwater treatment is very important as it reduces the pollutants (sediment and phosphorus)
from entering our public waters. With the newly added storm sewer infrastructure as part of the
street reconstruction project in the area, it is imperative this wetland maintenance is completed so
it functions as designed to best treat the stormwater before it enters Lake Minnewashta.
QUOTES RECEIVED
The City of Chanhassen solicited quotes from three contractors on December 8, 2017. Three
quotes were received. The low quote for this project was from Widmer Construction. This
contractor has completed work in Chanhassen in the past and their work has been acceptable.
