Summary

The commission approved multiple preliminary plats and site plans Dec. 4, including the Enclave at Brook Hollow and a five‑lot commercial subdivision at 24 O'Fallon Square, and recommended rezoning and a conditional use permit for Stonebridge Commons to city council. Residents raised safety and traffic concerns during public hearings.

The City of O'Fallon Planning and Zoning Commission on Dec. 4 approved a slate of preliminary plats and site plans and voted to forward a rezoning and conditional‑use permit for the Stonebridge Commons senior and villa development to the city council.

Commission staff presented multiple items on the agenda, and commissioners voted to approve the Enclave at Brook Hollow preliminary plat for a 20‑lot single‑family subdivision at 845 Feis Road and a five‑lot subdivision at 24 O'Fallon Square, among other items. The commission also recommended rezoning approximately 8 acres to R2 and approved the preliminary plat and conditional‑use permit for Stonebridge Commons, with the site plan approved subject to an additional lighting review at the Mexico Road/Old Canals Road corner.

Why it matters: The approvals clear the way for near‑term construction activity — including 20 houses in the Brook Hollow area and a residential and assisted‑living campus at Canal/Mexico — while leaving several conditions (road‑inspection agreements, sidewalk and lighting improvements, and recorded cross‑access covenants) to be satisfied during the improvement plan and permitting stages.

Votes at a glance

- Enclave at Brook Hollow (preliminary plat, 845 Feis Road): motion to approve carried (Mover: Vice chairperson Nunnery; Second: Cascola). The commission approved staff recommendations, with a clarified condition specifying the developer is responsible for repairs for damage occurring after construction documentation.

- 24 O'Fallon Square (preliminary plat): approved; staff required recorded indentures/covenants addressing cross‑access and shared parking.

- Strawberry Farms (display house plat, four lots with parking): approved.

- 100 Highway P (site‑plan grading): approved.

- 7136 South Outer Road 364 (dermatology building addition, site plan): approved.

- Stonebridge Commons (rezoning recommendation to R22; preliminary plat; conditional-use permit for senior overlay; site plan): all motions carried. The site‑plan approval included an added condition that a photometric/street‑lighting plan be reviewed for the Old Canals Road/Mexico Road corner.

Public comment and conditions

Residents raised recurring concerns during several public hearings: the presence and fall zone of an existing radio tower at the Enclave site, potential construction damage to local streets, sidewalk connectivity and traffic increases on Brook Hollow Drive, and the loss of commercially zoned land at the Stonebridge site. Staff and applicants responded that inspections, escrows or maintenance agreements, and required conditions would address many of those concerns, and counsel for the owner described the radio tower as a preexisting use built in 1983 and compliant with current fall‑zone rules.

What happens next: Approved preliminary plats and site plans must still satisfy conditions and proceed through improvement plan submittal and permitting; Stonebridge Commons will be considered before city council in two weeks as the commission forwarded a recommendation on rezoning and the conditional use permit.
