GRAND RAPIDS (WZZM) -- The city is now in the second phase of its "MyGRCityPoints" program, which rewards residents who volunteer.

Mayor George Heartwell and city manager Greg Sundstorm demonstrated how the program works at an event Tuesday morning.

Residents can earn points by volunteering at approved non-profit events. Those points can be redeemed for discounts at locally-owned businesses.

People can also donate the points to a city park. The park that receives the most points will receive $50,000 in improvements.
