Williamsport is an incorporated town, so Town Hall handles planning, zoning and building permits rather than Washington County. The town site posts a building permit application, a zoning ordinance and a zoning map. No special-event or temporary-structure rule turned up, and its pages are silent on the historic district and floodplain. Byron Park pavilions and Springfield Barn are reserved in person with a contract and hold-harmless form. The Washington County Health Department's event requirements could not be verified.
- Pavilions and the barn are booked through Town Hall with a rental contract and hold-harmless form.
- Williamsport Historic District has been on the National Register since 2001.
- Cushwa Basin and the towpath are part of C&O Canal National Historical Park.
Ask Town Hall which part of Byron Memorial Park is open to a trailer before the event date, and check the live Canal Days dates, since two town pages disagreed.
