Plan for sprawling subdivision back on track

After raising concerns last week, board recommends complex sewer plan for 178-acre Stonewall Farms

The Stonewall Farms residential development is back on track after initial disagreements on how sewer infrastructure would be structured for the neighborhood caused a slight delay.

Plans for the development, which will eventually encompass 178 acres and bring an additional 350 housing units to the village, had progressed since initial plans were approved in September 2021, but hit a road block after a Feb. 7 special Board of Public Works meeting.

The meeting was called to discuss a sewer plan submitted by developer Robert Tillman. The plan had sewer infrastructure running only to the north, rather than a portion of it being sent to the south as discussed in early conversations with the village.

The subdivision will be bordered by Highway 60 to the south, West Cedar Creek Road to the north, Keup Road to the west and Green Valley Road to the east, on what is currently agricultural land.

For sewer to be run to the north, several thousands of feet of new pipe would need to be laid, extensive upgrades would need to be made to the Ninth and 11th Avenue lift stations and large portions of existing sewer line would have to be upgraded. Most of the sewer line would also be installed under a wetland area, which requires permission from the Wisconsin Department of Natural Resources, the village would have to acquire easements on portions of the land and the area may present maintenance challenges for utility staff members.

Running sewer to the south would require the installation of a new lift station and upgrades to another lift station.

While Tillman would finance any utility infrastructure installed on the development property, the village will be responsible for long-term maintenance once the development is completed.

Concerned about access to manholes needed to maintain the sewer lines, the Board of Public Works voted against the sewer plans — temporarily putting the project on hold.

The Board of Public Works discussed the project again on Feb. 14.

Public Works Director Amber Thomas said after review of the sewer proposal, village staff members found that running sewer lines to the north rather than the south was the best option — primarily because it would save the village from maintaining a new lift station.

“Staff has come to an agreement that long-term maintenance of a lift station would not be desirable for anyone. That would be costly infrastructure for us to own and maintain on a daily basis,” she said.

While running sewer lines north would be the most cost-effective option, Thomas said village staff members are still concerned about access to manholes, which would require easements for the village to send crews out to.

“The pathway that is currently on the plans is the best path for long-term maintenance but our biggest concern that remains is access,” Thomas said.

Tillman agreed to install gravel roads so utility crews can easily access the manholes for maintenance. The roads will be a minimum of 15-feet wide and consist of compacted materials capable of withstanding 60,000 pounds.

The Board of Public Works unanimously recommended the Village Board approve an amendment to the development’s pre-annexation agreement, which includes details on the sewer infrastructure and utility crew access to it.

The Board of Public Works also recommended approval of a construction inspection services contract. Through the contract, Tillman will hire inspectors from Daar Corp. to inspect sewer infrastructure for the development.

The Village Board will consider both of the recommendations Monday.

Following approval from the Village Board and Wisconsin Department of Natural Resources, construction on the first phase of the development is expected to begin immediately.
