THE CORNERSTONE GROUP
SPRING PARK, MINNESOTA
CLEANUP
PROJECT SUMMARY
|
|
|
To clean up this 9-acre property on Lake Minnetonka, Landmark
prepared and received rapid approval from the Minnesota Pollution Control Agency of the Voluntary Response Action Plan and
Environmental Contingency Plan. Rapid approval was required to demolish buildings and remediate soil prior to constructing
two multi-story retail (1st floor) and residential (2nd, 3rd and 4th floors) buildings with underground parking at this waterfront
Property.
|
|
In addition to the excavation and disposal of contaminated soil
on this fast-paced redevelopment project, the remedial design included a system to prevent migration of vapors from volatile
organic compounds in groundwater into the two buildings: installing a vapor barrier and passive venting system beneath the
buildings.
|
|
|
During remediation and construction, Landmark dealt with several
environmental contingencies including the removal of eight underground storage tanks. Landmark staff prepared a successful
grant application to Hennepin County’s Environmental Response Fund, which paid for $48,000 of the environmental cleanup costs
related to the vapor barrier and passive venting system.
