Wheeler Center Wetland Mitigation OK’d

By

At its Jan. 9, 2012 meeting, the Ann Arbor city council approved a $331,589 contract with TSP Environmental to do maintenance and restoration of a wetland mitigation area at the Ann Arbor Wheeler Service Center located on Stone School Road.

When the Wheeler Service Center was constructed in 2005, the Michigan Department of Environmental Quality (MDEQ) required the creation of 2.59 acres of new wetland – made up of 2.23 acres of forested and 0.16 acres of scrub/shrub wetland. Because the areas have proven to be wetter than anticipated, the required number of trees and shrubs did not survive the original planting.

Correction of the problem includes the installation of new drainage channels and culverts, the armoring of a stormwater swale and removal of sediment. TSP’s bid was the lowest of three received. The other two were from Verdeterre Contracting Inc. ($392,425) and CTI and Associates Inc. ($723,934).

This brief was filed from the city council’s chambers on the second floor of city hall, located at 301 E. Huron. A more detailed report will follow: [link]
