Planning commission postpones 19 Iva Street subdivision after staff recommends denial and public record concern

The Hilton Head Island Planning Commission postponed a public hearing on a proposed subdivision at 19 Iva Street after staff recommended denial and a member of the public told the commission he had information suggesting the lot might already have been subdivided.

Trey Lyle, Development Services program manager, told the commission that the applicant proposes splitting the parcel at 19 Iva Street into two lots to allow construction of a second dwelling; a 4,981-square-foot home is currently under construction on the property. Lyle said the property falls in the RSF-5 zoning district and the Forest Beach overlay, which imposes a 0.45 floor-area-ratio (a 5,000-square-foot cap for single-family lots). He said a variance to exceed the cap was denied by the Board of Zoning Appeals in June 2024 and that staff’s analysis concluded adding one lot would “result in additional vehicle trips” and would decrease the utility of community rights-of-way — findings that led staff to recommend denial under the commission’s five review criteria for deviations from previously approved major subdivisions.

The five criteria, explained to commissioners by planning staff member Shay, require a finding that a proposed change “is not detrimental to the reasonable investment-backed expectations of owners of lots” and direct reviewers to consider off-site parking and utility burdens, impacts to subdivision amenities, overcrowding, noise and traffic, and diminished utility of open space or rights-of-way. Shay also noted that the current process — adopted in March 2023 — routes deviations to the planning commission and adds mailed and posted notice for adjacent properties; she reminded the commission that appeals of planning decisions must be filed in circuit court within 30 days of notice of the decision.

Commissioners asked several technical questions about how density is counted in the subdivision, how remaining density units are allocated, and whether exemptions for single-family dwellings affect calculations of pervious versus impervious area in the overlay. Lyle said lot size and zoning determine allowable dwelling units and reiterated that single-family lots in the overlay are generally exempt from a specific impervious-area percentage except for pools and decks.

During public comment, Curtis Coltrane said he had recently received information indicating the lot in question may already have been subdivided and asked the commission to postpone the hearing so staff could verify the records. Coltrane said the subdivision “appears to have been approved by the town” long ago. The applicant agreed to the delay.

Following that exchange, the commission voted unanimously to postpone consideration of the 19 Iva Street application to the Jan. 15 meeting so staff can check records and the parties can prepare. The meeting packet shows staff recommended denial based on increased trips and decreased utility of rights-of-way under the commission’s adopted criteria; no final decision on the subdivision was made.

What happens next Staff will verify deed and subdivision records for 19 Iva Street and provide updated information to the commission ahead of the Jan. 15 meeting. The commission’s next scheduled meeting on that date will include public notice and full consideration of the matter unless the applicant withdraws or another procedural change is requested.
