Artificial turf for dog parks, daycares and kennels: the functional-turf question, washdown water and odor

01Can a daycare, kennel or dog park yard be artificial turf here?

The harder question comes with new construction. Since January 1, 2026, Colorado towns may not allow nonfunctional artificial turf in new development or redevelopment on commercial, institutional and industrial property or HOA common property (HB25-1113). Functional turf stays allowed: artificial turf in “a recreational use area or other space that is regularly used for civic, community, or recreational purposes,” such as playgrounds, sports fields and parts of parks. Dog yards aren’t named either way.

A 2025 Western Resource Advocates guide suggests towns ask applicants to “label functional turf and functional artificial turf areas and describe the proposed functional use” (WRA). On a daycare or dog park plan, mark the yard as a dog exercise area.

Town codes that reach a dog yard:

Beyond Dacono’s dog parks, none of these codes says whether a daycare play yard is functional turf, or even landscaping. It depends on the town: in Fort Collins, ask Fort Collins Planning, labeled plan in hand. Other property types are on the commercial turf page.

02What do Colorado’s kennel rules say about a turf yard?

Colorado’s Department of Agriculture licenses boarding and training facilities under the Pet Animal Care and Facilities Act, inspecting each first (CDA). Its rules, 8 CCR 1202-15, never mention artificial turf, so they neither approve it nor rule it out. They set what any yard surface has to do:

• Drain. Outdoor areas must drain excess water “regardless of surfacing material within the area” (Rule 11.12.9), and standing water must be removed from common areas (12.1.8).
• Stay clean. Visible waste comes out of common areas daily or more often (13.3), and a common area is cleaned, then sanitized, after one group of dogs leaves and before the next arrives (13.2).
• Come out when soaked. “Outdoor substrate must be removed or replaced when permeated with urine or fecal matter, or when odors are present” (13.11). Until July 15, 2025, the rule said “gravel, sand, or soil” (earlier text). Substrate plainly covers sand infill and the crushed-rock base under turf; whether it also covers the turf is a question for the PACFA office.
• Have shade. Animals in an outdoor area need shade above 70 degrees unless they can go straight inside (11.12.3, 11.12.6).

One distinction matters. A play yard where dogs mix is a “common area.” A run where a dog eats and sleeps is an “enclosure,” and the floors listed for a dog enclosure don’t include turf by name; one option is an “other surface approved by the Commissioner” (12.1.7). Ask the PACFA office before turf goes into boarding runs.

03Where can the washdown water go?

Not to a storm drain. In Fort Collins, storm sewers carry runoff to the creeks and the Poudre River without treatment, and the city lists pet waste among the pollutants (Fort Collins Utilities). The code bars sending untreated polluted or contaminated water to streets or storm drains, directly or by letting it migrate there (Sec. 26-498). Contaminated water includes “nutrients such as nitrogen and phosphorous” and disease-causing biological agents (Sec. 26-491); NC State Extension notes “the concentrated nitrogen and excess salts in dog urine” (NC State).

The sanitary sewer isn’t automatic either. Fort Collins bars stormwater, surface water and subsurface drainage from it unless the Utilities Executive Director authorizes it in writing (Sec. 26-331), and bars connecting areaway drains or other surface-runoff sources to a sanitary line (Sec. 26-258). An open yard catches rain and snowmelt as well as rinse water, so its drain sits between the two systems. Settle the outlet in writing with whoever provides your sewer service before the base is designed.

Other towns draw the storm-drain line the same way:

Dog parks aren’t exempt. In 2023 Firestone permanently closed two dog parks that sat in detention ponds, citing its state stormwater permit and the bacteria in pet waste (Town of Firestone). Solids: see dog poop on artificial turf.

04How should a busy yard drain on clay?

It carries more liquid than a home dog run. PACFA lets up to 60 dogs share one common area, with a supervisor for every 15 (Rule 14.11). One distributor rates its ordinary turf for 1 to 3 pets and its fully permeable pet turf for kennels and dog parks, warning that liquid held between drainage holes can cause “lingering odors” (Synthetic Grass Warehouse). Some kennel turf, ForeverLawn’s K9Grass for one, needs no infill (spec sheet). See pet turf vs regular turf and turf infill for dogs.

Under the base, much of Northern Colorado is clay. The Colorado Geological Survey says expansive clays can swell up to 20% by volume when wet (CGS), and Longmont notes that its “clay soils absorb water slowly” (City of Longmont). Liquid that gets through the base faster than the clay takes it in runs along the top of the clay to the low side. For a facility yard:

• A planned low point. Slope the ground under the base to a collection point with an agreed outlet, away from the building.
• Zones. Rule 13.11 can mean replacing soaked substrate, so lay out the yard so one corner’s turf and base can come up while the rest stays open.
• Winter. Rinse water that can’t drain freezes in the turf. See does artificial turf freeze.

The base itself is in what base goes under artificial turf and artificial turf on clay soil.

05What cleaning routine keeps a turf yard from smelling?

The smell is ammonia made from the urea in urine, and warmth speeds it: Montana State University Extension, studying the same reaction in fertilizer, says a rise from 45°F to 60°F can double the loss to the air (MSU Extension). NOAA’s Greeley UNC station averages 58.3 days a year at or above 90°F (NOAA normals). More in dog urine smell on artificial turf. The routine below draws on PACFA and one kennel-turf maker’s care guide (K9Grass guidelines):

• Two products, two jobs. The guide says disinfectants kill germs but don’t necessarily remove the source of odor; enzymes break down the source without necessarily killing germs.
• Heat is a poor fit. PACFA’s other sanitizing method raises the surface to at least 160°F, and the same guide says water above 160 degrees shouldn’t be used on its grass.
• Dogs out while you clean. Animals must be protected from water under pressure and cleaning chemicals (13.4). Two yards that rotate make hours-long enzyme treatments workable.

Drought rules can limit hosing: see do you have to water artificial turf. For summer heat, see how hot artificial turf gets.

06What should a daycare or kennel ask before the yard goes in?

• “Where does rinse water go, and has the sewer utility agreed?” A good answer names the outlet and shows the utility’s written reply; a storm inlet is the wrong answer.
• “Does this backing drain across the whole sheet?” With dozens of dogs, it matters.
• “Infill or none, and how does a soaked section get replaced?” A good answer shows how one zone comes up.
• “Which cleaners and water temperatures can this turf take?” Get the maker’s written care guide and check it against your disinfectant’s label.
• “Is the yard labeled as a functional area on the plan?” On new construction, it should be.
• “May I see the spec sheet and PFAS documentation?” Colorado has barred installing turf with intentionally added PFAS since January 1, 2026 (SB24-081).
