RE: Approval of Purchase of Wetland Mitigation Credits for the James Road Area and the
National Guard Armory Area Storm Water Detention Basins from Wolf River Basin
Mitigation Bank/$96,000
BACKGROUND
The James Road Area Detention Basin and the Armory Area Detention Basin projects require mitigation
of impacts to wetlands. The Wolf River Mitigation Bank has opened up wetland mitigation credits for
general sale. The Wisconsin Department of Natural Resources and the Army Corps of Engineers have
determined that purchasing credits from this wetland bank is an acceptable option for mitigating the
unavoidable impacts to wetlands at both sites.
ANALYSIS
During the design of the James Road Area Detention Basin and the Armory Area Detention Basin, it was
determined that there would be an unavoidable impact to 1.6 acres of wetlands. During the permitting
process for both projects, it was determined that the City would mitigate these impacts through the
creation of wetlands at the James Road Area Detention Basin, as there were no available mitigation
banks within the Wolf River Watershed. Since that time, the Wolf River Mitigation Bank has been
approved to sell mitigation credits. Due to the significant monitoring and maintenance effort required for
the City with wetland mitigation, the Federal and State agencies prefer applicants to purchase mitigation
bank credits rather than performing onsite mitigation.
FISCAL IMPACT
The purchase of these mitigation bank credits will cost$96,000. The purchase of these wetland
mitigation credits allows for the following savings vs. the original plan of permittee-responsible mitigation:
Construction Cost: $173,000
Minimum 8-Year Monitoring Cost (estimated): $60,000
Minimum 8-Year Maintenance Cost(estimated): $40,000
Total Construction /Monitoring /Maintenance Cost: $273,000
Total Cost Savings: $177,000
RECOMMENDATION
Staff recommends approval of the resolution.
