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)
Memorandum
Attached for your approval is a resolution to petition the Washtenaw County Water Resources Commissioner (WCWRC) to undertake a project to design and implement stormwater control measures throughout the City, through a Citywide Tree Planting Project.
These improvements will reduce the amount of stormwater entering the City's stormwater piping network and reduce contaminant loading to the downstream creeks and the Huron River. The proposed improvements will improve water quality and reduce localized flooding in the project areas. The trees will be planted during the fiscal year 2016 (Fall 2015 and Spring 2016).
The Huron River is subject to a total Maximum Daily Load (TMDL) restriction by the state of Michigan for suspended solids, E. coli and phosphorous. 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 be $400,000.00.
As the Water Resources Commissioner will be assessing the City over a maximum of 20 years for this project, the City will not have to expend the full cost of this project at the time of construction. Rather, the reimbursement of the Water Resources Commissioner will be paid over the financing period, with installments not-to-exceed $24,500.00 per year. The first payment will be included in the proposed Storm Water Fund Operation and Maintenance Budget for FY16 and subsequent payments will be included in the annual stormwater budget submittals. The resolution authorizes the annual payment to the County for this project from the Storm Water Fund (Fund 0069) pending annual budget approvals by Council.
