Colorado Conditions That Matter for Events
Across the 113 Colorado places listed here (NOAA 1991–2020 normals by nearest station):
- 10 of 113 listed places average 60+ days a year at 90°F
- None of the 113 listed places are in the wet band (46+ inches a year or 12+ days with an inch)
- All 113 listed places average 30+ nights a year at 32°F
For most of the state, the event season is bounded by freezing weather; winter events rely on units without running water unless winterized models are available.

By Climate Region
By DOE Building America climate region (county level, PNNL guide), the planning focus shifts: Cold (107 places): an outdoor season limited by long freezing winters; Very cold (3 places): the shortest outdoor season, with snow access in winter; Mixed-Dry (3 places): staking against wind and units that cope with cold winters.

How Many Units
The PSAI chart sizes event restrooms by crowd and hours, assuming no servicing during the event:

|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |

| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a five-hour event of 1,000 people, the chart gives 9 units; with alcohol, 10 to 11, and at least 1 accessible unit per cluster.
Who Handles Local Rules
For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, the government to ask depends on where the site is. Of the 113 listed Colorado places, 77 are incorporated, 36 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
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 (at least 5% of each cluster) and hand-wash stations
- Delivery and pickup windows the venue allows
