Why does flood-prone ground matter for a portable toilet?
A portable toilet is light when empty, so water or wind can move it. Do not place a unit in a low spot or on ground that holds water, and ask the provider about anchoring on soft or sloping ground. Riverside sites in the region have a history of flooding.
Conshohocken lies on the Schuylkill and has a Flood Plain Overlay District. USGS reports map Schuylkill flooding from Conshohocken to Philadelphia for the August 24, 1933 and August 19, 1955 floods. Darby Creek in Delaware County has flooded repeatedly in more recent storms. None of that means a given trail event will flood. It means the question belongs on your checklist before the units arrive.
The practical steps are simple. Choose the highest firm ground the landowner allows, keep units away from the water's edge, and tell the provider about the surface. Do not assume a unit that sits securely on a dry afternoon will stay put after a storm. If heavy rain is forecast for the event, call the provider early; do not try to move units yourself.
What waterfront venues and events around Philadelphia draw crowds?
The Camden waterfront has the 25,488-capacity Freedom Mortgage Pavilion, which hosts about 40 headline acts and festivals a year. Chester's Subaru Park holds 18,500 for soccer and 26,000 for concerts. The Schuylkill hosts the Dad Vail Regatta, usually in May, and Fishtown's Penn Treaty Park hosts community events.
The Freedom Mortgage Pavilion at 1 Harbour Blvd in Camden is an outdoor amphitheater that works in summer. Subaru Park sits beside the Commodore Barry Bridge in Chester, and a 100-acre waterfront master plan is changing the ground around it. On the Schuylkill, the Dad Vail Regatta has been listed with more than 3,000 competitors from 125 colleges, in a 2018 listing, and is usually held in May.
Penn Treaty Park in Fishtown marks William Penn's 1682 meeting with Chief Tamanend, and its Friends group and others use it for events. Cherry Street Pier hosts The Foundry. These sites are smaller, but a crowd on a park lawn needs toilets just as surely as a stadium does. For stadium-day demand see concert and stadium-area toilets.
How are units secured in wind and on soft ground?
On soft ground, slopes or exposed sites a unit must be anchored or ballasted, because an empty unit is light enough to go over. The provider decides how, after you describe the surface and exposure. Never try to secure, tip or empty a unit yourself.
Waterfront parks are open by design, and a breeze that nobody notices on a street can push on a tall plastic box. Describe the exposure plainly: a bare lawn, a pier, a hilltop trail section. The more the provider knows, the better it can choose a spot and a way to hold the units down.
Keep units clear of the walkways crowds use, of exits and of any accessible route. Ask the provider to check the site before the event, if that is possible, and call again if rain changes the ground the night before.
Do riverfront building sites need the same planning?
Yes, with a longer horizon. Chester's waterfront master plan is transforming 100 acres, and University City sits on the Schuylkill's east bank, where Schuylkill Yards is a multi-year build. Long projects need standing units, scheduled servicing and placement above any ground that has flooded.
Event planning is about a day or a weekend. A riverfront construction site is about months, and the same questions apply for longer: is the spot above the high-water line, can the service truck reach it in wet weather, and who confirms placement with the landowner? Conshohocken's Flood Plain Overlay District shows that zoning itself treats riverfront ground as a special case.
For multi-month projects, see long-term portable toilet rental, and for the crew-size rule that governs most building sites, see construction site portable toilets. Tell the provider early that the site is beside a river so it can plan for it.
