Board of Public Works approves three stormwater maintenance agreement amendments for local properties
Summary
The Board of Public Works approved three amendments to stormwater maintenance agreements tied to new or replaced stormwater facilities at 411 North River Road, Good Shepherd on Decorah Road, and Wiggle Ware on Schmidt Road; agreements formalize long-term maintenance of new best-management practices required by the city's MS4 permit.
The Board of Public Works voted Aug. 18 to approve three amendments to stormwater maintenance agreements required under the city’s Municipal Separate Storm Sewer System (MS4) permit with the Wisconsin DNR. Staff said the agreements ensure property owners will construct and maintain newly installed stormwater treatment devices to design specifications.
Max (city engineering/stormwater staff) described the first amendment as addressing a previously incomplete stormwater plan at 411 North River Road. The property owner designed a new stormwater feature that includes a biofilter basin with 18 inches of engineered soil; the city issued an amended stormwater management permit and requires a maintenance agreement to ensure long-term upkeep.
The second amendment covers Good Shepherd on Decorah Road, where a surface pond will be replaced by an underground storage-and-treatment device; the new best-management practice requires a new maintenance agreement tied to the amended facility.
The third amendment is for Wiggle Ware along Schmidt Road, where reconstruction of a south parking lot and perimeter pavement will reduce paved area but still requires installation of facilities for total suspended solids (TSS) removal; the maintenance agreement obligates the property owner to ongoing upkeep.
Board members moved and seconded each amendment during the meeting and approved them by voice vote. Staff recommended approval of all three agreements based on plan reviews and the city’s responsibility under its MS4 permit to make sure stormwater facilities are built and maintained.
Why it matters: The amendments formalize long-term maintenance responsibilities for stormwater facilities. Proper construction and upkeep of biofilters, underground storage-treatment devices and TSS removal systems are intended to reduce runoff and pollutant loads to local waterways as required by the MS4 permit.
