Council approves stormwater maintenance agreement for Creek Edge Phase 1 subdivision

WEST BEND, Wis. — The Board of Public Works on Sept. 22 approved a stormwater maintenance agreement tied to a stormwater management permit for Creek Edge Phase 1, a proposed subdivision that will create 11 single-family lots and an outlot containing stormwater facilities.

Max (city engineering staff) told the board these maintenance agreements are standard whenever a new development receives a stormwater permit, and that they help the city comply with its Wisconsin DNR MS4 permit obligations. The proposed development, an extension of Daisy Drive labeled Daisy Place, will direct on-site runoff to an east-side wet pond and a drainage swale along the south property line. "This plan collects all the water from those properties in the development and directs it to the east," Max said, adding the design releases runoff at the same or lower rate than predevelopment to manage quantity and quality.

Aldermen asked whether the new pond and swales would reduce water intrusion on back yards of existing properties on Creek Road; Max said the swale along the south end of the new lots will intercept runoff from the development and direct it to the pond, likely reducing flows toward those neighboring lots.

The board voted to approve the stormwater maintenance agreement; there were no recorded nay votes. The agreement references compliance with Chapter 23 of the municipal code and Wisconsin NR 151 requirements.

Why it matters: The permit and maintenance agreement obligate the developer and future property owner to construct and maintain stormwater facilities designed to preserve predevelopment runoff rates and manage water quality, which can reduce neighborhood flooding and help the city meet MS4 permit requirements.
