Planning commission backs code changes that shrink residential buffers, revise subdivision process

The Columbia County Planning Commission on Wednesday recommended approval of three text amendments to the county code that would change how concept plans are handled, halve the typical residential buffer and update landscaping standards.

Planning staff and commission members said the package is intended to streamline subdivision review and ease development friction while preserving review safeguards. "The biggest thing here is that the 50 foot buffer is getting cut in half to 25 feet on residential properties," Will, a county planning staff member, told the commission during the discussion. He said the change would be paired with a requirement that buffers be owned and maintained separately — typically by a homeowners association — rather than being placed on individual lots.

Why it matters: The buffer change drew the most debate at staff and community meetings before Wednesday’s hearing because it alters a long-standing standard that affects lot layout, tree preservation and future lot owners’ maintenance obligations. Staff said the change aims to balance post-storm safety concerns, development feasibility and the long-term preservation of green space by placing buffers on dedicated, maintained parcels rather than individual lots.

Key details: The commission voted to recommend changes to three code sections: Chapter 74 (subdivision procedures and concept-plan handling, referenced in the meeting as Section 74-36), Chapter 90 Section 90-139 (buffers and screening), and Chapter 90 Section 90-140 (landscaping requirements). Staff said the Chapter 74 revisions will allow staff to not return a concept plan to the commission if the rezoning already included a concept plan and subsequent plats do not substantially change that plan. Chapter 90 changes clarify buffer ownership, allow plan-review flexibility for berms and adjust street-tree spacing from 40 to 45 feet (25 feet for smaller street trees), staff said.

Discussion and safeguards: Staff and commissioners repeatedly stressed that some code provisions remain: more intensive projects that trigger major site grading will still be subject to technical engineering review, and use of adjacent non-developable areas (floodplain, publicly owned land) as part of a buffer would be reviewed case-by-case. "We will look at that in plan review," Will said. Public safety, sightlines at intersections and fire-code requirements will continue to be enforced through site plan and permitting review, staff added.

Next steps: The commission’s recommendation is advisory; the package will go to the Columbia County Board of Commissioners for final consideration at its May 6 meeting, staff said.

Despite the changes the commission approved, staff and commissioners said development reviews and engineering checks remain in place to verify grading, drainage and sight-line safety during permit and site-plan reviews.
