Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Buffalo, NY station, about 5 miles away.
Conditions for Events
DOE's Building America map puts Erie County in the Cold climate region (IECC 2021 zone 5A, PNNL county guide). Winters in this region are long enough that freezing, not heat, is usually the main limit on units that carry water.
Freezing Nights
About 124 nights a year drop to 32°F or below, more than three in four U.S. places in our data, so freezing weather covers a large part of the year. Winter events here are cold-weather events: standard units without running water are the dependable choice, with sanitizer inside; if you want sinks or a trailer, ask for winterized or heated models.
Outdoor Season
Summer heat is rarely the problem here; cold is. Outdoor events from late fall into spring need units that cope with freezing nights.
Local Settings
For winter events, clear and pack a path for guests and for the service truck before setup.
How Many Units
The Portable Sanitation Association International (PSAI) chart sizes event restrooms by crowd and hours, assuming no servicing during the event:
| Crowd | 1 hr | 2 hrs | 3 hrs | 4 hrs | 5 hrs | 6 hrs | 7 hrs | 8 hrs |
|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |
| 1,000 | 4 | 6 | 8 | 8 | 9 | 9 | 11 | 12 |
| 2,000 | 5 | 6 | 9 | 12 | 14 | 16 | 18 | 20 |
| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a winter event, take 1,000 people over three hours: the chart gives 8 units. If alcohol is served, PSAI adds 10–20%, which is 9 to 10 units after rounding up. For accessibility, 5% of 10 is 0.50, which rounds up to 1 ADA unit in a single cluster; split into 2 clusters of 5, each cluster needs its own, so 2 ADA units in total.
See the PSAI event chart for the full table.
Placement and Access
Put restroom rows on firm, level ground the service truck can reach, away from food prep, with ADA units on an accessible route and hand-wash stations beside the rows.
Snow and Access
Average snowfall is about 95 inches a year, more than nine in ten U.S. places in our data, enough to bury a ground-level path several times a winter. Winter events need a cleared, packed path for guests and for the service truck, and an ADA unit needs that path cleared all the way to its door.
Who to Ask About Local Rules
Amherst is a town, a county subdivision with its own local government rather than an incorporated city. For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, ask the Amherst town government before you book what applies.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours, and whether it runs over several days
- Whether alcohol or food will be served
- ADA units for every cluster (at least 5%, rounded up) and hand-wash stations
- Winterized hand-wash stations for cold-season dates
- A cleared path for guests and the service truck
