2010 Pond Cleanout Project No. SWMP18D: Approve Quotes and
A ward Contract
PROPOSED MOTION
"The City Council approves the quotes and awards a construction contract in the
amount of $66,852.50 with Kusske Construction Company for the 2010 Pond
Cleanout Project No. SWMP18D-09-01."
City Council approval requires a simple majority vote of the City Council present.
BACKGROUND
In order to meet water quality treatment and rate control standards, it is necessary
to maintain a minimum volume within a given pond. Ponds are designed to trap
sediment and this entrapment of sediment leads to a reduction in volume within
the pond necessitating regular maintenance of the ponds. Based upon field review
by City staff as well as resident concerns, eleven ponds were sampled in 2009
according to MPCA protocols for possible dredging. These ponds are shown on
the attached map.
In addition, Chanhassen is an MS4 City permitted under the National Pollution
Detection and Elimination System (NPDES). Under our NPDES permit, we are
required to inspect 20% of our ponds annually and maintain these ponds to their
design parameters.
On January 14,2009, quotes for this cleanout were requested from Kusske
Construction Company, Minger Construction Company and Parrott Contracting.
The three quotes received are summarized as follows:

Base Bid $47,862.50 $51,689.90 $66,734.50
Bid Aft 1 $13,355.00 $17,498.80 $16,104.50
Pond 9 $5635.00 $23,782.30 $7,188.50
Total Bid $66,852.50 $92,971.00 $90,027.50
Based upon the three quotes received and the previous work performed by Kusske Construction
Company in the City of Chanhassen, staff is recommending approving the lesser quote submitted
by Kusske Construction Company and authorizing the pond cleanout work be performed by
Kusske Construction Company. Staff is recommending that five of the eleven tested ponds be
cleaned this year. The remaining six ponds will receive top priority in next year's dredging
schedule.
DISCUSSION
Staff is requesting the Council approve the quotes and authorize the construction contract with
Kusske Construction Company. These ponds are high priority ponds and staff has received
numerous comments on the need to clean these ponds.
Braun Intertec sampled each of the ponds included on the map. In all cases the ponds were
found to be below the threshold for Soil Resource Value (SRV) 1. Therefore the excavated pond
sediments may be reused without restrictions.
FUNDING
The project is planned to be funded with the Surface Water Management Plan (SWMP) funds
and was identified in the 2010 CIP SWMP-032. Staffhad budgeted $25,000 from SWMP funds
for the project. The proposed road improvement project on Audubon Road has made the need
for adequate storage and treatment of increased importance in this area. Because of this need
pond location #7 was included in the base bid. This pond is by far the largest pond requiring the
largest volume of sediment removal. This pond alone accounts for nearly 60 percent of the
project cost and over 70 percent of the volume of sediment to be removed. Staff is
recommending that funding for pond location #7 come out ofthe Fees for Services budget in the
Surface Water Management Fund as this pond would likely not have been included in the
scheduled pond cleanout were it not for the timing ofthe proposed Audubon Road project.

Description I Total Project Cost: $205,000
This project will provide inspection and cleaning if required of all City stormwater ponds on a rotating four (4) year schedule, to identify any
management needs and perform needed repairs and improvements. This may include sediment removal, placement of blanket, rip-rap or other
erosion control BMP's, vegetation management and assessment, repair and replacement of inlet and outlet structures.
Justification I
There are over 170 stormwater ponds in the City of Chanhassen, all requiring regular maintenance to assure they function to National Urban
Runoff Program recommendations. This measure has also been identified in Chanhassen's National Pollution Discharge Elimination Municipal
Separate Storm Sewer System permit.
