Planning Commission gives preliminary approval to Alluvium subdivision with staff conditions

The Dickson County Planning Commission voted to recommend approval of the preliminary plat for the Alluvium subdivision, a mixed-lot proposal at 660 Piney Road, with conditions and staff corrections to be addressed before final platting. The roll-call vote was 7–2 in favor.

The recommendation matters because the proposal converts a large tract along the Piney River corridor into smaller residential lots—1.5-acre lots at the front and 5-acre lots at the rear—with a homeowners association and new road and water infrastructure proposed. Commissioners said the subdivision replaces a previously considered RV-park plan and raised traffic, floodplain and septic concerns that staff must resolve before final approval.

Commissioners and staff listed outstanding corrective items: confirm FEMA flood-map citations for flood-prone parcels; provide a clear answer on whether individual lots will use septic or community systems; replace an incorrect form submitted for planning-commission review; and include sight-distance assessments where new driveways or roads are proposed. Planning staff said they will enforce all applicable subdivision regulations and will review any proposed HOA bylaws before final approval.

Several commissioners urged caution about construction impacts on narrow local roads. One commissioner said the area’s roads “are not designed for semis, cement trucks, grama trucks,” citing potential congestion and safety problems during build-out. Commissioners also noted Lot 5 contains roughly an acre of buildable land above the floodplain and identified a suitable building envelope there.

Staff reported a preliminary hydrology review and that the applicant had provided a FEMA flood-map citation; a more detailed hydrology and septic review will be required at site-plan stage. The commission added as a condition that staff comments and commissioner stipulations be addressed and that the applicant submit any required letters from the Water Authority of Dickson County before recording.

The commission’s recommendation now goes to the Dickson County Commission, with final plat approval conditioned on the technical corrections and documentation requested by staff and commissioners.
