## What renting a porta potty in Boulder is actually like

Boulder sits right against the Flatirons, and it is not Denver, Fort Collins, or Lakewood, so we do not service it like any of them. Three local realities shape almost every Boulder order: a regulated floodplain along 16 major drainageways that covers about 15 percent of the city, the same creeks that took more than 17 inches of rain in one September week in 2013; downslope windstorms that the National Weather Service says can reach 60 to near 100 miles per hour in and near the foothills; and a city right-of-way that cannot be fenced off for private use, where containers and materials need a permit. Here is how each one changes what we recommend.

### Why Boulder's foothill wind and heavy snow change how a unit is set and serviced

Wind is the first thing we plan for in Boulder. The National Weather Service office here says the areas around Boulder are especially prone to extreme downslope wind, warm, dry Chinook winds that come down off the mountains at 60 to near 100 miles per hour in and near the foothills and can top 100 in extreme cases, mostly in the cold season. A standard portable toilet is tall and light when its tank is low, so on open lots, new foundations, and park lawns we set units in the lee of a building or fence where we can, stake or strap them, face doors away from the west, and keep them off slopes. When a high wind warning goes out, we can check and re-secure units before the gusts arrive.

Snow is the second. The city's long-record weather station averages about 93 inches of snow a season and about 138 nights at or below freezing, far more snow than the plains cities east of here. We winterize units with a non-toxic antifreeze charge from fall into spring, swap running-water hand-wash stations for sanitizer when it freezes hard, and set units near the driveway or a cleared path so the pump truck can reach them after a storm. Summers are warm and dry, with about 33 days a year at 90 degrees or more, so from June through August we add a mid-week visit for large crews and busy events.

### Boulder's floodplain: 16 drainageways and the lesson of September 2013

Boulder was built where creeks leave the mountains, and the city regulates a floodplain along 16 major drainageways that covers about 15 percent of Boulder and more than 2,500 structures. September 2013 showed why. At the city's weather station, 9.08 inches of rain fell in a single observation day, and more than 17 inches fell from September 9 through 16. That is the kind of rain the floodplain rules are written for, and water moves fast on a foothill slope.

That changes where a unit goes. Boulder's floodplain code exempts temporary items not attached to the ground, like tents and traffic control devices, from a floodplain development permit only if they will not affect the flow of the conveyance zone or high hazard zone, or if they stay no more than 30 days, and it bars obstructions in the conveyance zone. So for a job or event near a creek or a creekside path, we set units outside the mapped conveyance and high hazard zones, on high, firm ground, and tell you if a longer rental near the water needs a check with the city's floodplain staff. Big event days, like the BOLDERBoulder 10K on Memorial Day, get the same treatment: units on high ground, away from drainage paths, with a lane left for the service truck.

### Placement and the City of Boulder right-of-way permit

On private property with clear truck access, a driveway, a fenced jobsite, or a private lot, you generally do not need a city permit for a portable toilet. Boulder is strict about anything beyond that line. The City of Boulder says rights-of-way belong to the city, not the adjacent owner, and cannot be fenced off for private use, and that storing construction materials there requires a permit. Its code says trash dumpsters, materials, storage trailers, and construction trailers may not be placed in the right-of-way unless approved with a right-of-way permit, only a licensed right-of-way contractor may apply, a traffic control plan is required, and right-of-way work normally runs from 7 a.m. to 5 p.m.

Portable toilets are not named in those rules, so we plan every Boulder job to keep units on private ground first: in the driveway, inside the fence line, or on the lot, never on a sidewalk, bike path, or curb ramp. Many Boulder lots are tight and sloped toward the mountains, so we look for a level spot the truck can back up to. If the street is the only option, tell us the exact address and we confirm what it needs and coordinate with the City of Boulder Planning and Development Services right-of-way staff before delivery.

## Porta potty rental in Boulder, CO: FAQs

### How much does a porta potty rental cost in Boulder?

A standard portable toilet in Boulder, CO starts at $270 for a weekend rental (up to 7 days) or $320 per month, with 4 service visits included in every 28-day rental. Upgrades: deluxe flushing units run $374/weekend, ADA-accessible units $374/weekend, luxury restroom trailers from $1610/weekend. Every Boulder rate is all-inclusive: delivery, pickup, fuel, and environmental and local fees are built into the one price, so there are no surprise line items. Online orders are $0.39 higher than the phone price; either way, we deliver and service the unit ourselves. Enter your ZIP for your exact Boulder rate.

### How many porta potties do I need for a Boulder jobsite (OSHA)?

OSHA's construction sanitation rule, 29 CFR 1926.51(c)(1), sets the floor: 1 toilet for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers from 20 up to 200; and 1 toilet seat and 1 urinal per 50 workers above 200. OSHA also expects a worker to reach a toilet within about a 10-minute walk. On a Boulder jobsite we recommend sizing above the OSHA minimum, anchoring units against downslope winds that can reach 60 to near 100 miles per hour, and winterizing through about 138 freezing nights a year. Tell us the crew size and we will size the order to the standard.

### How often should portable toilets be serviced in Boulder?

Our standard Boulder monthly rental includes 4 service visits over the 28-day period, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and hand sanitizer. In summer we add a mid-week visit for large crews and busy events. From fall into spring we winterize, since Boulder averages about 93 inches of snow and about 138 freezing nights a year, and we check anchoring on each visit because a unit with a low tank is easiest for the wind to move. Service is built into the rate, so compliance never depends on anyone remembering to call.

### Do I need an ADA-accessible unit for my Boulder event?

For an event open to the public, yes. The 2010 ADA Standards for Accessible Design require that at least 5 percent of the single-user portable toilets in each cluster be accessible, with a minimum of one, and each accessible unit is marked with the International Symbol of Accessibility. (Units provided only for construction workers are exempt.) In practice a small Boulder event needs at least one accessible unit; a larger one needs one per every 20 standard units. ADA units in Boulder run $374 for a weekend. The accessible unit has ground-level entry, interior grab bars, and a full wheelchair turning radius, and it needs firm, level ground with a clear approach path. Tell us your guest count and we will build the right ratio in.

### Do I need a permit for a porta potty in Boulder, Colorado?

On private property in Boulder, a driveway, a fenced jobsite, or a private lot with clear truck access, you generally do not need a city permit for a portable toilet. The right-of-way is different. The City of Boulder says rights-of-way cannot be fenced off for private use and that storing construction materials there requires a permit, and its code bars trash dumpsters, materials, and storage or construction trailers from the right-of-way unless approved with a right-of-way permit, which only a licensed right-of-way contractor can request, with a traffic control plan. Portable toilets are not named, so tell us the exact address and we confirm what your spot needs and coordinate it with the City of Boulder before delivery. Near a creek, we also check the floodplain map.

### What is the difference between a standard, deluxe, and restroom trailer in Boulder?

A standard unit is the jobsite and everyday-event workhorse: enclosed, stocked, and cost-effective at $270/weekend. A deluxe flushing unit adds a foot-pump flushing bowl and an in-unit sink for guest-facing events like weddings and corporate functions at $374/weekend. A luxury restroom trailer is a climate-controlled, multi-stall unit with porcelain toilets, running-water sinks, and mirrors, indistinguishable from a fine-venue bathroom, from $1610/weekend. Pick by how guest-facing the site is and how long the rental runs.

### Can I get same-day or weekend porta potty delivery in Boulder?

Yes. We deliver and service portable toilets throughout Boulder and the surrounding Boulder County area, with same-day and next-day drop-offs available in most of the area when you book early. Weekend event units are delivered clean before your event and picked up after. Enter your ZIP or call (866) 858-3867 and we will confirm the soonest available delivery for your address.

### Do you rent hand-wash stations in Boulder?

Yes. A freestanding hand-wash station pairs with any toilet unit and needs no power or water hookup: it has a foot-pump faucet, soap, and paper towels, stocked at delivery and every service visit. One station serves roughly four toilet units, the ratio most health departments expect. For food and drink events in Boulder, plan a station near the vendors and one near the toilets to cover both inspection points.

### Can a portable toilet go near a creek or in the floodplain in Boulder?

Sometimes, but we plan it carefully. About 15 percent of Boulder sits in the regulated floodplain along 16 major drainageways, and the city's code bars obstructions in the conveyance zone. Temporary items that are not attached to the ground are exempt from a floodplain development permit only if they will not affect the flow of the conveyance or high hazard zone, or if they stay no more than 30 days. So we place units outside those zones on high, firm ground whenever we can, and for longer rentals close to a creek we tell you when a check with the city's floodplain staff makes sense. September 2013, when more than 17 inches of rain fell at the city's station in a week, is why we do not take chances near the water.
