Addison planning commissioners debate UDC adoption amid concerns over timing, impervious cover and nonconformity rules

The Addison Planning and Zoning Commission spent the bulk of its Feb. 18 work session debating whether to recommend a new Unified Development Code to the City Council, with commissioners raising questions about timing relative to the town’s comprehensive plan, inspection authority and rules governing impervious cover and nonconforming properties.

Staff presented the UDC draft and told commissioners it had received two public-comment submissions shortly before the meeting: one from Jimmy Neiman and a stapled set from Lee and Roseanne Hopwood, who asked to speak at the regular meeting. “We received, as of 45-ish minutes ago, two public comments,” Leslie Knipe, director of development and neighborhood services, said while introducing the UDC agenda item.

Several commissioners said they were sympathetic to waiting until the town’s updated comprehensive plan is adopted before finalizing the UDC. “Comprehensive plans are done so infrequently and we’re just about to approve one,” a commissioner (S2) said, calling it reasonable to consider delaying a final recommendation to avoid a future conflict. Staff replied that the draft UDC complies with the current comprehensive plan and that both documents can be amended later if needed.

Commissioners pressed staff on specific technical and legal points. A staff member who reviewed the draft (S9) said the inspection language allows entry only with consent, exigency or an administrative warrant and added, “warrantless inspection is not going to be proper,” indicating the draft includes procedures for obtaining a warrant when required. Knipe and staff said the town does not employ an in-house surveyor and that a “chief city surveyor” title was removed from the draft; third-party engineering or developer-submitted certifications would be used for survey-related determinations.

A recurring and detailed point of disagreement centered on the UDC’s treatment of nonconforming properties and which party carries the burden to prove nonconformity. One commissioner (S2) urged changing the language so the town must prove nonconformity rather than placing the burden on the property owner, saying the current draft reads as if owners must prove they are conforming. “You’re presumed until the town asserts otherwise and goes through an administrative process,” that commissioner said. Staff and other commissioners responded that administrative and court processes already require staff to identify the specific code section violated and to provide evidence if the town pursues enforcement, and they noted practical constraints — such as the need for sealed surveys or site plans to certify conformance.

Commissioners also focused on impervious-cover standards. Staff explained the draft removed an explicit impervious-cover percentage in some single-family areas to avoid creating widespread nonconforming situations on small lots, replacing it with other dimensional and driveway-approach standards and relying on the town’s stormwater code for runoff management. A commissioner worried this could allow front-yard paving to increase and asked where protections for neighbors appear in the UDC; staff said standards limiting driveway approaches and other dimensional controls remain and that stormwater regulations elsewhere in town code address runoff concerns.

On process, staff outlined options the commission could adopt: recommend approval as drafted, recommend denial, or recommend approval with specific conditions or language changes to be forwarded to council. Commissioners discussed whether they could recommend approval “with staff review” on wording; staff said a recommendation with suggested language is acceptable and council retains final authority.

The transcript records a nomination and a second for the vice-chair position (Chelsea). That nomination was made and seconded during the work session but the transcript does not record the final roll-call vote on that leadership item. The UDC discussion likewise produced no recorded final vote or formal recommendation in the work-session transcript.

The commission ended the work session and took a short recess before the regular meeting; the UDC item was left with staff to provide clarifying edits and possible language changes to address the commissioners’ concerns before any formal recommendation is reflected in the minutes or forwarded to City Council.
