Attached for your review and approval is a resolution to award a construction contract to Erie Construction, LLC in the amount of $79,556.00 for the Wetland Mitigation at Leslie Park Golf Course Project.
In the summer of 2017, a modern roundabout was constructed at the intersection of Dhu Varren Road, Green Road, and Nixon Road to improve the intersection's capacity, operational efficiency, and road safety for all users.

However, since the bank is located outside of the City of Ann Arbor, the local mitigation at a 1:1.5 ratio located with the city limits was required to meet the City of Ann Arbor wetland mitigation ordinance. To ensure proper wetland function and value replacement, the local mitigation was proposed within the same sub-watershed as the impacts (Traver Creek) by means of wetland creation at the City of Ann Arbor owned Leslie Park Golf Course. In addition to the 1:1.5 ratio, an additional 10% of the impacted area is to be created to ensure the suitable area requirements are achieved and to guarantee no net loss of wetland resources within the City of Ann Arbor.
