Title
Resolution to Petition the Washtenaw County Water Resources Commissioner for the City of Ann Arbor FY16 Tree Planting Project in the Huron River Green Infrastructure Drainage District (Total Cost: $400,000.00; City's Apportionment: $400,000.00)

Since the project focus is on water quality improvement, it is eligible for low-interest (2.0%) State Revolving Fund (SRF) loan funding, and this project has been included on the Project Priority List (PPL) for SRF loan funding. This project has been classified as a "green project," which may result in up to 50% loan forgiveness.
A formal petition from the City is required to move this project to implementation. The Huron River Green Infrastructure Drainage District is an established Chapter 20 County Drain. Therefore, the work to implement control measures falls under the jurisdiction of the Washtenaw County Water Resources Commissioner. As an established drain, the costs of the project are assessed to the governmental entities within the drainage district area. The total cost of this project is estimated at $400,000.00. The City's apportionment of this drainage district is 100% of the district. Therefore, the City's share will b...
