Council approves Ivy Park rezoning to residential PUD; applicant commits to 8-foot sound wall

The Manassas Park governing body on Oct. 21 approved rezoning (RZ2025‑01) that converts vacant industrially zoned property into a planned-unit residential development (Ivy Park) and granted related zoning and public-facility manual waivers. The applicant’s representative, Janelle Cameron (participating remotely), described minor changes since the planning commission review.

Key commitments from the applicant included a fence along the northern property line adjacent to the city-owned industrial parcel: a minimum eight-foot height and a minimum STC (sound transmission class) rating of 23. Staff and the applicant said the rating reflects VDOT’s minimum for certain sound barriers and that fence density and thickness affect performance; council members queried STC 23’s real-world performance and asked for clarity about materials because STC 23 provides modest attenuation (staff described STC 23 as roughly equivalent to a thin wall/hollow-core door and noted higher ratings would provide materially better sound insulation). The applicant also agreed to reduce the timeline for removal of overhead utility conflicts from 12 months to six months in the proffers.

During the review councilmembers divided on a requested buffer reduction; after discussion the majority approved the package as submitted (the applicant noted the industrial neighbor operates typical daytime hours and that the revised fence commitment reduced noise concerns). Council authorized the rezoning and approved multiple waivers and public-facility manual relief items noted in the motion.

Council directed staff to ensure the sound-wall details and material specifications are reviewed in the final plats and proffers so the wall provides meaningful noise mitigation.
