Council reviews draft "estate lot" and conservation residential zoning; staff stresses no automatic rezoning

At a city workshop, council members and planning staff discussed draft ordinance language to add two new zoning districts to the city’s code: an R‑1E “estate lot” district and a conservation residential district intended to preserve open space while allowing the same overall dwelling density as conventional development.

Planning staff member Jim told the council that the proposed districts would be added to the zoning ordinance only and would not change any property’s zoning unless a property owner requested application of the new district. “Nobody’s land is being proposed for rezoning at this time,” he said.

The proposed R‑1E district largely copies permitted uses from the existing R‑1 single‑family district but raises development standards. Suzanne, a planning staff presenter, said the draft sets the minimum lot area for R‑1E at 14,000 square feet, compared with 10,000 square feet in R‑1, and increases minimum lot width to 100 feet; the text also includes specific language addressing detached garages and accessory dwelling units (ADUs).

Council members asked whether the new rules would preserve the character of older master‑planned neighborhoods such as Tillman Estates. One council member suggested using an overlay to protect those neighborhoods from down‑zoning or subdivision that would alter long‑established lot patterns; staff said an overlay is an alternative and that the new district is one tool among several to achieve the council’s aims.

The conservation residential district, as described by Jim, is intended to preserve contiguous open space and environmental features while keeping total unit counts similar to conventional subdivisions. Staff proposed a 4 dwelling‑units‑per‑acre maximum, a 15‑acre minimum project size to qualify, and a requirement that at least 35% of a site be preserved as common open space with 60% of that open space in a contiguous tract. The draft would allow a mix of housing types — single‑family, duplexes/semi‑detached units, townhouses and ADUs — while requiring that at least 10% of units be on half‑acre or larger lots and that townhouses remain a small share of the total (10% maximum).

Staff also proposed ADU rules tied to owner‑occupancy: ADUs would count as half a dwelling unit toward overall density, would require at least one parking space and would have a minimum lot size (6,500 square feet) when proposed. Jim said the ADU rules are intended to encourage housing for aging parents or students while preventing short‑term rental conversions: “you would not be able to rent them for a period shorter than 30 days, so that would stop them from becoming short term rentals.”

Council members pressed staff about setbacks, driveway access and whether side setbacks should increase with the larger lot widths to accommodate rear‑loaded garages or ADUs; staff said they would consider changes (for example, increasing side setbacks from 10 to 15 feet) and could include asymmetric options where appropriate.

A recurring question was how to prevent developers from clear‑cutting sites or using administrative variances to avoid tree‑preservation commitments made earlier in the review process. Resident Dana Brown raised that concern directly at public comment, saying she had seen developers go to the BZA for variances that she believed undercut planning commission tree‑saving conditions: “I have repeatedly seen the developers come back through the BZA and ask for a variance to backdoor you guys and undercut all the work that you did and the planning commission did,” she said. Jim responded that the draft district would rely on existing sketch plan requirements and planning commission oversight to identify and protect significant trees and features and clarified that the entire 20‑foot perimeter buffer would be maintained by the development’s homeowners association.

On process, staff told council the draft would be subject to the typical public‑review steps. Council members asked whether the proposal must return to the planning commission; staff said the ordinance has already been reviewed by the planning commission and would not need to go back unless substantial changes were made. Councilmembers indicated they would schedule readings as required.

Next steps for the council include continued refinement of the ordinance text and possible amendments after the first applications or developer feedback. Staff warned that, because the conservation residential option requires a fairly large minimum parcel, the city may see only specialized developers propose such projects, and that some numeric standards (minimum acreage, buffer sizing and open‑space accounting) could be adjusted after practical experience.

The workshop closed after brief public comment and a motion to adjourn.
