Oakland County will plant five trees donated by The Detroit Zoo in Mack-Rowe Park in Royal Oak Township on Earth Day. The tree planting is part of the OAKSTEM tree planting grant program initiated by Oakland County Executive Dave Coulter’s administration and the Oakland County Board of Commissioners which seeks to improve the environment by supporting storm water management planting trees throughout the George W. Kuhn Drainage District. Royal Oak Township is among 14 communities in the district, all of which have encountered significant flooding during heavy rains in recent years. Oakland County Water Resources Commissioner Jim Nash donated the $10,000 matching funds to Royal Oak Township from his 501(c)(3), Pure Oakland Water.
