Summary
Adams County treats any amplified sound in its parks, trails, and open-space areas as an automatic "general nuisance" under Rule 12(a), unless the sound is part of a leased event at Riverdale Regional Park or the user first gets consent from the POSCA Department. A citation is a $100 civil infraction, and rangers can eject offenders on the spot.
It is unlawful for any person to engage in any conduct or activity within an Adams County park, trail, waters, or open space area, or facility which a person knows, or reasonably should know, will substantially interfere with the use and enjoyment of such places by others, the health, safety, and welfare of users or neighbors nearby, or which may constitute a general nuisance. As used herein, "general nuisance" means an unreasonable or unlawful use of the area, including but not limited to any noise, action or odor that could substantially interfere with any other person's lawful use or enjoyment of the area. The use of amplified sound shall constitute a general nuisance under this Rule unless it is made for leased events at the Riverdale Regional Park or consent has been obtained from the Adams County POSCA Department.
Full Breakdown
Rule 12 of the county's POSCA Rules and Regulations, Resolution 2022-649, bans any conduct in an Adams County park, trail, waters, or open-space area that a person knows or reasonably should know will substantially interfere with others' use and enjoyment, with health, safety, and welfare, or that otherwise amounts to a "general nuisance," defined to include noise, action, or odor causing substantial interference. Amplified sound is singled out for stricter treatment: Rule 12(a) declares that its use "shall constitute a general nuisance under this Rule" automatically, without requiring proof that it actually disturbed anyone, unlike the broader noise/action/odor language that still needs an interference showing.
The only two ways around the ban are a leased event at Riverdale Regional Park or advance consent from the Adams County POSCA (Parks, Open Space and Cultural Arts) Department. § 29-7-101(2)-(3), with jurisdiction in Adams County Court.
Violations & Fines
A Rule 12(a) amplified-sound violation is a civil infraction under C.R.S. § 29-7-101(2) and § 16-2.3-102(1)(a), carrying a $100 fine per violation plus court fees and surcharges. Article IV.6 also lets a Park Ranger or deputy eject the violator from the area immediately, on top of any fine.
