Derby planning commission advances wide-ranging zoning, subdivision amendments; schedules public hearing

The Derby Planning Commission reviewed a package of proposed amendments to the city's zoning and subdivision regulations at its March 2025 meeting and voted to set a public hearing for 6:30 p.m. on April 3, 2025, to consider formal adoption.

Planning staff presented a draft package that would change how Derby treats window signs, temporary signage, certain commercial uses, driveway landscaping requirements, screening of mechanical equipment, accessory-structure height limits, special-use review for mini-storage east of Rock Road, design criteria for duplexes, and drainage review for planned unit developments (PUDs). "We don't exempt window signs," planning staff said, explaining the proposal would treat window signage like wall signage and limit coverage to the same area rules that apply to wall-mounted signs.

The package includes several numeric clarifications staff said were intended to resolve recurring enforcement problems. Under the draft, temporary signs would be allowed for 45 days (same for residential and nonresidential properties), with staff authorized to grant extensions of up to 30 days. Staff also proposed requiring that, when a driveway crosses a street-yard planting area, the required planting or ground-cover on the right-of-way side still be installed and shown on site plans.

Other proposed changes would: - Create an "office/retail flex" use permitted in the B-3 district with design limits (to allow storefronts that combine office and storage/workspace where B-5 and M-1 zoning is not present on the east side of Derby); - Require clearer screening of ground-mounted mechanical equipment so such equipment is concealed by planting or compatible screening materials; - Increase allowable height for accessory structures in certain cases so a two-story accessory building (for example, a dwelling unit above a garage) can be permitted; - Prohibit large temporary gatherings within the accident potential zone (APZ) of McConnell Air Force Base where current regulations otherwise allowed broad temporary-use permits, after staff said it found the code could be interpreted to authorize unlimited gatherings in that zone; - Add a special-use process option for mini-storage proposals on the east side of Derby so such uses can be considered case by case without rezoning the corridor; and - Add explicit drainage review language to PUD provisions so increased density and altered building layouts trigger drainage impact review.

Commissioners asked clarifying questions during the staff presentation. Commissioner Ryan asked whether the required ground-cover in street-yard planting strips would be specified on site plans; planning staff replied that applicants must show what they will install so staff can approve or reject it during site-plan review. Commissioner Heseltine asked, "When's the last time you've had communications with McConnell Air Force Base on their APZ to see if that has changed?" Planning staff said they met with the base's consultant the prior year and that the APZ limitation arose after staff observed temporary gatherings at a private site that could occur within the APZ.

The meeting also included a previously submitted, unsigned letter read aloud by planning staff that asked, "Why are you adding another housing area to Derby?" Planning staff responded that the comprehensive-plan implementation and recent housing study show projected demand for additional housing, and noted the comprehensive plan was adopted by the planning commission and the city council.

Commissioner Eamon, speaking during the public forum portion, urged residents to participate and defended the commission's work, saying, "There's no kickbacks here," and encouraging residents to attend meetings and use the public-comment process.

The commission voted to set a public hearing for the proposed zoning and subdivision regulation amendments on April 3, 2025, at 6:30 p.m., and directed the secretary to publish notice in the official city newspaper at least 20 days before the hearing. The meeting record shows a separate earlier vote to accept the February 20, 2025, meeting minutes (7 in favor, 2 abstentions). The commission noted its next regular meeting is scheduled for March 20, 2025.

A public hearing and a formal recommendation to city council will follow the April hearing; staff emphasized that no regulatory changes were adopted at the March meeting and that the purpose of the session was to set the hearing and receive feedback on the draft amendments.
