Developer introduces Custer Lane PRD proposal; commissioners flag sewer and stormwater questions ahead of Nov. 12 public hearing

Developer Luke Kolbeck introduced a conceptual planned residential development (PRD) for a roughly 12-acre parcel at N80 W18303 Custer Lane (tax key 62.989), describing a clustered layout with 10 duplex-style condominium units (20 condominium units total) and one to three future single-family lots on the southern portion of the site.

Planner Amy Bennett said the property is currently zoned A-1 Agricultural and the applicant seeks a comprehensive-plan amendment to change the land use from institutional to low-density residential and subsequent rezoning to a PRD. The planning commission took the item as an introduction; there was no action tonight. Bennett said the required public hearing for the comp-plan amendment will be at the Planning Commission on Nov. 12 and that rezoning would proceed later to the Village Board.

Commissioners and staff raised several technical and policy questions. Key issues included sewer allocation (staff's materials noted a sewer allotment or capacity reference of 20 units), stormwater management and discharge (staff and the applicant noted Custer Lane is about 14'2 feet higher than the rear of the property and that conveying stormwater uphill to that right of way poses design challenges), and wetland delineation and permitting for a mapped tributary to the Fox River that crosses the site. The applicant said wetlands were mapped and that the tributary is not a navigable waterway; commissioners asked for documentation on jurisdictional determinations and noted permitting would be required to alter wetlands.

Kolbeck said the developer's intent is to keep the south portion as open space until development of adjacent properties (the Herb Gross parcel) proceeds and that the condo layout was chosen to minimize impacts on neighboring backyards. He also said the applicant had discussed price and unit sizes in the materials: the ordinance draft cites estimated average sale prices in the $500,000 to $650,000 range and unit sizes around 1,700 square feet.

Ending: The commission took the application as an introduction with a public hearing on the comprehensive-plan amendment set for Nov. 12; staff and the applicant will address sewer allocation, stormwater strategies and wetland-permitting questions as the project advances.
