Full Breakdown
m. ' This provision sits within Chapter 13-1's broader park use rules; a companion general provision, Section 13-1-5(A)(5), separately bars disturbing 'the peace and quiet of other users with unreasonable noise, indecent behavior, or offensive conduct' at all city parks, but only the Standley Lake section fixes a specific decibel limit and clock hours. Standley Lake Regional Park is additionally closed to the public from sunset to sunrise except for authorized camping under Section 13-1-16(F), so the quiet hours largely overlap with the park's separate overnight closure for day users while applying around the clock to campers.
Violations & Fines
Violating the quiet-hours or decibel limit is enforced under the general Chapter 13-1 penalty, Section 1-8-1, W.M.C., per Section 13-1-4(B), and Standley Lake Regional Park staff or law enforcement officers may eject a violator under Section 13-1-3(B). Anyone in the park after the sunset-to-sunrise closure is additionally subject to citation for trespassing under Section 6-3-5, W.M.C.
