Argyle planners approve narrower nonresidential noise limits, retain prohibited-activities list
Summary
The Planning & Zoning Commission approved an amendment splitting residential and nonresidential noise rules, setting a 62 dB property-line standard for nonresidential uses (5-minute measurement) with a 1-minute 15 dB spike violation and keeping a list of prohibited activities for enforcement.
The Argyle Planning & Zoning Commission on May 6 approved revisions to Article 8.02003 (noise) that preserve existing residential and agricultural noise limits while creating a distinct nonresidential section with stricter, uniform standards.
Harrison, town planning staff, explained the rewrite separates dash 1 (residential/agricultural; unchanged) from dash 2 (nonresidential). For nonresidential uses the draft sets a single property-line standard of 62 decibels (conversational level at about three feet) measured over a five-minute period. Staff also adopted a one-minute 15-decibel spike rule for short-duration loud events: if a sound meter shows 15 dB above the 62-dB standard (about 77 dB) for one continuous minute, that would constitute a violation even if the five-minute average meets the standard.
Staff said the commission chose to keep a list of prohibited activities (section D) so that enforcement remains possible when environmental conditions or meter placement prevent an accurate measurement. The ordinance also includes speaker/equipment restrictions for nonresidential sites, such as requiring speakers to be oriented inward and not toward adjacent residential properties.
Commission discussion focused on enforcement practicality, equipment availability and edge cases (for example, construction sites, county maintenance yards or private amenities that straddle residential and nonresidential uses). A commissioner noted that retained prohibited-activity language helps enforcement when wind or other conditions prevent reliable meter placement.
Commissioner Uvic moved to approve the ordinance amendment; Commissioner Nelson seconded. The motion carried 6-0.
The approved changes will be forwarded to Town Council for consideration (as part of the ordinance amendment process). Staff advised that the nonresidential limits are intended to protect adjacent residences from perceived loudness increases while giving code enforcement tools for short, high-intensity events.
