Planning staff presents proposed subdivision control changes on open space, sidewalks and lot frontage

Jeff Burton of the Planning Department presented revisions to the city's Subdivision Control Ordinance at the Feb. 4 Columbus City Common Council meeting, laying out a three-tier open-space requirement, changes to sidewalk timing, and revisions to lot-frontage and replat procedures.

Burton said the Planning Commission formed a working group with planning and parks staff and recommended the changes unanimously. The proposed open-space requirements apply only to new residential subdivisions and are tiered by size: subdivisions of 1'49 lots would see no new requirement; subdivisions of 50'299 lots would be required to set aside common open space starting at one-half acre for 50 lots and increasing by a half acre for each additional 50 lots; and subdivisions of 300 or more lots would generally require a neighborhood park with a five-acre minimum, scalable by the number of homes.

The draft disqualifies unusable land such as floodway areas or stormwater retention basins from qualifying as required open space. The proposal envisions that, for most small and medium developments, the open space would be maintained by homeowners associations; the ordinance also allows an initial option for a developer to offer the land for dedication to the city, and gives the city or Columbus Parks Foundation a first right of refusal if an HOA later seeks to convert the open space to lots after a set period (the draft referenced a five-year period for HOA decision-making).

Burton said the draft includes a half-mile walking-distance exemption: if a proposed subdivision is within a half-mile walkable distance of an existing public park and that park is actually reachable (including via sidewalks or pathways built by the subdivider), the open-space requirement may not apply. He emphasized that a park required under this same ordinance for one subdivision would not count as the exemption for neighboring subdivisions.

Planning commission changes also remove the longstanding requirement that someone proposing a lot split in an existing subdivision obtain signed consent from 75% of other owners; that consent requirement would be replaced by a set of considerations the Planning Commission must weigh (infrastructure, character of the neighborhood, and similar impacts). The draft also clarifies sidewalk rules for minor subdivisions (requiring sidewalks before recording where no financial guarantee is posted) and makes that practice consistent with planning commission precedent.

Burton and commissioners discussed serial subdivisions and how the ordinance counts cumulative lots if the same subdivider files adjacent plats over time; the draft does not attempt to address cumulative development by a succession of different subdividers on adjacent parcels. Residents and council members asked about how the rules apply to existing large plats with later additions, and staff said the draft contains specific applicability language for those scenarios. Public comment included questions from a Claremont Drive resident about parks in sparsely developed corridors; planning staff offered to follow up during master-planning efforts.

No formal council vote on the subdivision revisions was recorded at the meeting; the item was presented for first reading and discussion with a planning commission recommendation.
