Plan Commission sends Illinois Street townhomes rezoning to committee after tree, buffering and design questions

John Davosiewicz, land-use professional with Nelson & Frankenberger, representing Pulte Homes of Indiana, asked the Carmel Plan Commission on Oct. 23 to rezone a 4.4-acre triangular infill parcel along Illinois Street and U.S. 31 for a planned-unit-development of three-story townhomes.

The developer has revised the proposal since the public notice: the application materials initially advertised 31 townhomes but the concept under discussion was reduced to 28 units, Davosiewicz said. He described the site as an infill parcel north of 106th Street, adjacent to commercial uses to the north and south and the Spring Mill Heights single-family neighborhood across Illinois Street to the west.

The commission’s staff report identified potential benefits and outstanding issues. “This development addresses several comprehensive-plan goals: variety of housing types, walkability, and preservation of mature trees,” said Steph, a Department of Community Services planner. Staff noted the proposed street would have a sidewalk on only one side and no street trees in the initial submission, requested a woodland evaluation and asked that the PUD text commit to specific tree-preservation and planting requirements and to the correct parking standard required by the UDO.

Commissioners pressed the petitioner on several areas: tree preservation and additional plantings, whether garages could be located at the rear instead of front-loading on the new street, and how to buffer new homes from adjacent commercial parcels such as Forte and Indiana Farmers Mutual Insurance. Several commissioners suggested the design should aim for a strong streetscape and more tree lawn if engineering will allow a narrower street cross-section.

Davosiewicz responded that the site is tightly constrained north–south by two stream corridors, an existing sanitary easement and a 25-foot floodplain setback, which pushes buildable area north and limits space for a standard tree lawn on both sides of the new street. He said stormwater would be handled by a dry pond outside the flood zone, and that the developer will submit a woodland evaluation and work with staff on revised architectural and landscaping details for committee review.

Commissioners also discussed noise from U.S. 31 and asked whether the developer would consider internal sound-mitigation measures inside the units or a contractual mechanism to oppose future state sound-wall installations. Davosiewicz said the petitioner would consider ways to document preferences (for example, via CCRs) and explore building-level mitigation.

After discussion, Commissioner Debbie Buckler moved to send the docket (PZ-2025-00184) to the Committee of the Whole for further discussion and review and to return it to the full commission; the motion carried. Staff and the petitioner said they will provide an updated tree inventory and more detailed plans for architecture, sidewalks, and buffering at the Nov. 4 committee meeting.

The petition remains under discretionary review; no rezoning or final approvals were granted on Oct. 23.
