Project Summary

The latter project will be located on property owned by the City of North Mankato immediately adjacent to Caswell Park. 

Project Description

Total project cost is $16.5 million dollars.  Local revenue available for the project is $6 million dollars generated from an existing sales and use tax extended by voters in 2016 and approved by the Legislature in 2017. The remaining $10.5 million dollars needed for the project is requested to come from a state of Minnesota bonding appropriation. 

$3.0 million dollars will complete upgrades to the existing Caswell Regional Sporting Complex (concession upgrades, restroom upgrades, parking lot addition, replace fencing, replace field lights, replace scoreboards, perform necessary site work, increase size of four fields to 300 feet, install knee wall and backstop nettings, provide additional spectator seating, replace the public announcement system, add gateway signage, and install turf field at Caswell North soccer complex.  The softball portion of Caswell Park is located on a 27 acre parcel (1,176,120 square feet of which 4,000 square feet is concessions).  The soccer portion of Caswell Park is located on a 17.5 acre parcel (762,300 square feet).  

$13.5 million dollars will be used to construct a 90,000 square foot indoor field house. The field house will include four full sized basketball courts and six tennis courts. The basketball portion of the facility can be converted into eight youth sized basketball courts or eight full sized volleyball courts. The tennis courts can be converted into 12 pickle ball courts.
