VII.1. Approval of Grant Agreement with the Minnesota Pollution Control Agency Central Park; Imihy
CITY OF HOPKINS
City Council Report 2025-114
To: Honorable Mayor and Council Members
Mike Mornson, City Manager
From: Laila Imihy, AICP – Special Projects and Initiatives Manager
Date: April 15, 2025
Subject: Approval of Grant Agreement with MPCA for Central Park
_____________________________________________________________________
RECOMMENDED ACTION
MOTION TO authorize staff to enter into a grant agreement for $4,999,782 with the
Minnesota Pollution Control Agency for Central Park.
OVERVIEW
At the April 15, 2025, City Council Meeting, staff provided an overview of the Central Park
project engagement, planning and status grants which may become available and grant
for which the City and the Nine Mile Creek Watershed District (NMCWD) have applied to.
Since that meeting, the City has been awarded $5 million dollars from the Minnesota
Pollution Control Agency (MPCA) through a Stormwater Implementation Grant to address
flooding and stormwater issues which regularly impact adjacent property, field quality
within the park, and downstream issues for Nine Mile Creek. Combined with the $1 million
dollars pledged by the NMCWD, the City is poised to leverage a minimum of $6 million
dollars of outside funding to transform Central Park.
Conversations with funding partners across the state have indicated to the project team
that grant funding for sustainability and stormwater efforts like we have seen the past
several years are unlikely to continue due to changes at the Federal level. Larger grant
funds which were identified such as Board of Water and Soil Conservation grants and
loans are unlikely to be available as expected. Should the City choose not to accept the
funds from the MPCA another opportunity for funding of this scale is not expected to be
available. In order to utilize the grant from the MPCA, the City must complete the project
by June 30, 2027, meaning that construction documents must begin being drawn up this
fall to prepare to send the project out for bid in early 2026, and begin construction in 2027.
A preliminary engineers estimate, which is attached, calculates the final project cost
conservatively at $13.9 million dollars. This includes a new lighted soccer field, new park
shelters – including a bathroom building on the east end of the park, construction of a
new and accessible playground, path reconstruction and realignment, repaving of parking
lots and the closure of the cut road from Mainstreet to Excelsior Blvd., and significant
stormwater, water quality, flooding and naturalization efforts throughout the park. The
south end of the park will become a formal headwater for the Nine Mile Creek, featuring
educational signage and markers.
Administration
The remaining costs could be paid in a number of ways:
• Bonding dollars which could be paid back through multiple means, such as using
future Park Dedication Funds or Storm Sewer funds. There are both completed
and approved development projects which are estimated to generate between $2
and $5 Million in Park Dedication Funds. The Storm Sewer fee has not been
increased since 2009, and a slight increase in this fee could contribute to bond
payments. Additionally, bonding which was done for Cottageville Park and Burnes
Park are set to be paid off in 2030 and funds which currently pay debt service on
these could be used to pay for Central Park improvements.
• Partnerships or sponsorships with local organizations such as Hopkins Area Little
League, Tonka United or other not yet known partners may be able to offset
smaller costs such as field lighting or field improvements.
• Smaller grants such as DNR Outdoor Recreation Grants, Hennepin County
Brownfields or Hennepin County Youth Activities Grants may be able to help offset
costs like playground equipment.
Tonight, staff will review the proposed park design and discuss the engineer’s estimate
and seek approval from the City Council to enter into an agreement with the MPCA for
the Stormwater Implementation Grant.
