INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for the 82
stall public parking lot within the Historic Millwork District. This parking lot will provide a
portion of the parking included in the development agreement with Novelty Iron Works.
DISCUSSION
The Capital Improvement Budget includes $3,280,151 to begin the development of
public parking within the Historic Millwork District. The parking will be constructed with
concrete curb and gutter and asphalt pavement. The parking lot will have lighting that
matches the street lighting used throughout the District and will be gate controlled.
A Phase I and Phase II Environmental Site Assessments (ESA) were completed for the
area, of the proposed parking lot, in May and June of this year. The Phase II ESA
found two areas that show elevated levels of contaminants above the Statewide
Standard for Contaminants in Soil. The environmental engineer provided the City with a
map documenting the extent of the impacted soils and made recommendations for
disposal of the impacted soils. The recommendation is to dispose of the impacted soils
at a landfill that is able to accept the material.
The Dubuque Metropolitan Area Solid Waste Agency (DMASWA) is capable of
accepting this material. The estimated volume of impacted soils to be disposed at a
landfill is approximately 1,600 tons. DMASWA quoted a price of $76.84 per ton for
disposal. Engineering has estimated that an additional $6.25 per ton would be needed
for trucking to this facility. The total fee per ton is estimated to be $83.09 per ton.
DMASWA does provide a rebate to the City of $6.73 per ton after three months. This
would reduce the fee to$76.36 per ton.
The City is exploring other options for the disposal of the impacted soils, in an attempt
to reduce project costs.
The quantity of impacted soils may vary depending on what is or isn't found during
construction. Excavation, along with additional soil sampling and testing, may find
additional impacted soils or determine a lessor amount of impacted soils needing to be
disposed of at a landfill.
The current construction estimate is based on disposal of the impacted soil at the
DMASWA facility until further testing can be completed during construction.
