Commission recommends PD rezone for 29‑acre industrial site with strict buffering, detention and grading conditions

The Planning & Zoning Commission recommended approval of a Planned Development (PD) rezoning to allow light industrial/warehouse uses on roughly 29.36 acres south of North Main Street near Knapp Road, subject to numerous deviations and conditions aimed at protecting adjacent residential areas.

Staff told the commission the PD would permit a base M1 (light industrial) zoning with numerous stipulations and deviations; most deviations increase rather than relax standards. Key staff‑recommended conditions include a 120‑foot buffer adjacent to residential properties (with multi‑layer landscaping and no dock doors facing homes), limits on illumination adjacent to residences, articulation and material standards for facades facing North Main, slope limits for landscape swales to ensure plant survivability (6:1 maximum along Main Street and 10:1 maximum adjacent to residential buffers unless a retaining wall is used), and on‑site detention. Staff said that a fault line required splitting one large building into two and that the project would likely require a traffic analysis and additional infrastructure work.

Applicant representatives (Hanover Companies) explained they will preserve FEMA‑mapped floodway areas, exclude floodway acreage from the open‑space calculation while still preserving it, provide a layered planting buffer (evergreen shrubs, ornamental trees and shade trees) to screen homes, prohibit dock doors toward neighborhoods and keep lighting shielded adjacent to residential areas. The applicant also proposed road improvements to Knapp Road; a development agreement discussed would have the developer front 10% of the road cost with the city funding the remainder under an EDC arrangement.

Nearby residents urged denial or stronger protections. Amy Bright and Victor King described prior flood events on adjacent streets, argued the corridor already floods and said heavy truck traffic and diesel fumes would degrade quality of life. Staff and the applicant responded that detention and roof drainage would be managed on‑site, that stormwater would be directed to a proposed dry pond discharging toward Clear Creek/Main Street, and that project conditions are intended to avoid increased runoff to neighbor yards.

Following discussion, the commission adopted the staff‑recommended PD with the listed conditions and deviations; the motion passed unanimously (6–0). The PD will proceed to City Council under the normal zoning‑change process.
