At its March 7, 2011 meeting, the Ann Arbor city council approved a $88,250 contract with J.F. New to conduct a study of the Swift Run drain system near the city’s composting facility. The study is prompted by a 2009 Michigan Dept. of Natural Resources and Environment (MDNRE) inspection. The inspection determined that a small pond near the northern compost pad required maintenance.
At that time, the MDNRE also requested improvements to the stormwater management system at the compost facility to reduce the impact of nutrient loading on the Swift Run drain. In 2004, the U.S. Environmental Protection Agency issued a Total Maximum Daily Load (TMDL) for biota in the Swift Run drain.
The concept behind the study is to examine the various interconnected ponds and ditches as a unified system, so that the MDNRE’s concerns can be satisfied. J.F. New was selected from seven engineering firms who responded to the city’s request for proposals.
