The Township is under a federal mandate to reduce phosphorus levels in Ford Lake in order to meet water quality standards.
Runoff from residential lawn fertilization is the primary source of phosphorus entering Ford Lake. By limiting the unnecessary application of phosphorus to lawns, the Township can reduce the amount of phosphorus entering the lake.
To achieve that goal, Ypsilanti Township passed an ordinance to eliminate the use of phosphorus in manufactured lawn fertilizers, effective January 2010.
Article IV Manufactured Fertilizer Ordinance
Sec. 66-76 Exemption for the use and application of manufactured fertilizer containing phosphorus
