Chairperson Powell stated there are approvals to be obtained from several other agencies and asked
if those approvals will be conditions of the Commission's approval. Mr. Zweber replied that they
will be conditions of approval and some of those approvals may be obtained by the next meeting.
Chairperson Powell asked if the City has received any feedback from Empire Township. Mr.
Zweber replied that staff has spoken with the chair and the township consultants. He stated that
Empire Township has different issues including that a lot of surface water runs into the Vermillion
River so that their groundwater monitoring will not focus on only well water but the river water
also.
Commissioner Weber asked about the access points hauling away from the mine and how the
additional truck traffic will be handled. Mr. Zweber stated that traffic will not head south on
Biscayne where the paving has ended. Also that the University will be expected to provide a
contribution for improvement of Biscayne Avenue in the future and Dakota Aggregate will not be
expected to contribute at this time. He further stated that Akron Avenue, south of County Road 42
is owned by the University, not the County. Mr. Zweber added that truck traffic will happen north
of the ballfields and will pass ballfield traffic during operation time. The traffic issues can be
discussed by the Planning Commission over the next three meetings.
Chairperson Powell asked if the City could assess for roadway improvements that may be as a result
of the additional truck traffic. Mr. Zweber responded that staff has begun verbal negotiations with
the University and Dakota Aggregates, and the City Attorney is working an agreement to address
those issues.
Mr. Zweber stated that all of the plans have been submitted to Dakota County requesting their
comments and staff should have their comments in time for the meeting on August 28`
Adjournment: There being no further business to come before this Commission, Chairperson
