Firestone CO Water Restrictions 2026

Current water restrictions in Firestone, Colorado

Firestone declared Stage 1 Mandatory Water Restrictions in spring 2026 as Colorado's lowest-snowpack winter on record squeezed Front Range water supplies. Outdoor irrigation is limited to two days per week by address parity, with a midday blackout from 10 a.m. to 6 p.m.

Firestone sits in the Carbon Valley area of southern Weld County — a stretch of the Northern Colorado growth corridor between Longmont and Fort Collins along Interstate 25. The town's population has doubled since 2010, driven by master-planned community development including Barefoot Lakes, Booth Farms, and Saddleback. That kind of growth is unusual for any small town and unusually demanding on water infrastructure even in non-drought years.

The combination of explosive growth, snowpack-dependent surface water, and a regional aquifer that has been measurably drawing down since the 2010s development boom puts Firestone in a structural water position that's tighter than many Front Range cities. Stage 1 in 2026 reflects the immediate snowpack reality; the broader concern is what happens in subsequent dry years if growth continues at the recent pace and aquifer levels keep declining.

The Carbon Valley communities — Firestone, Frederick, and Dacono — share infrastructure planning through the Carbon Valley Park and Recreation District and informal coordination on water-resource issues. The three towns face similar conditions but operate independent water utilities with separate rate structures and customer relationships.

Firestone's watering days and hours

Hand watering with a hose and shut-off nozzle is permitted on any day, outside the daytime blackout. Drip irrigation for trees and non-turf plantings is exempt from the day-of-week schedule.

• New sod and seed: 21-day establishment variance available through Firestone Utilities — register before installation.
• Master-planned community common areas: Barefoot Lakes, Booth Farms, and Saddleback common-area irrigation operates on the commercial schedule, with reclaimed water serving select common areas.
• Vegetable gardens: drip and hand watering allowed any day. Sprinkler-based vegetable gardens are scheduled.
• Pools: top-offs to replace evaporation are permitted; new fills require coordination with Firestone Utilities.

Violation fines and enforcement

Firestone enforces Stage 1 through Code Enforcement and Firestone Utilities with a progressive penalty structure under the town's drought ordinance:

• First violation: a written warning, logged against the customer account.
• Second and subsequent violations: escalating civil fines under the town's drought ordinance.
• Persistent or willful violators: Firestone Utilities can pursue service-restriction action.

Master-planned community HOAs are sometimes the first line of compliance enforcement, contacting residents about visible violations before the town is involved. This pre-citation contact is typical in HOA-heavy neighborhoods.

To report a violation, call Firestone Utilities at 303-833-3291 or use the town's online reporting form.

Other outdoor water rules

• Watering during measurable rain: prohibited. Functioning rain sensors required on automatic systems under Colorado law.
• Excessive runoff: water sheeting onto streets, sidewalks, or storm drains is a violation regardless of day or hour.
• Pressure washing: permitted only for surface preparation prior to paint, sealant, or repair.
• Decorative fountains: must recirculate water.
• Vehicle washing: permitted with a hand-held hose with shut-off nozzle, outside the daytime blackout.

How Firestone gets its water

Firestone's water portfolio:

• Colorado-Big Thompson (C-BT) project via Northern Water — Western Slope water delivered through the Adams Tunnel under Rocky Mountain National Park to East Slope allottees. C-BT is the largest single source for Firestone.
• Local groundwater wells in the Carbon Valley aquifer — a productive but declining shallow alluvial aquifer underlying the southern Weld County area.
• Reclaimed water for parks and select master-planned community common areas.

The Carbon Valley aquifer deserves a closer look. Groundwater in this part of southern Weld County is hosted in the alluvial sand and gravel deposits along the South Platte River and tributary drainages, plus underlying bedrock formations. Historic groundwater levels were stable through the mid-20th century; since the 2010s, however, the combination of rapid municipal growth (Firestone, Frederick, Dacono) and continued agricultural irrigation has driven measurable declines. Monitoring wells across the Carbon Valley show drops of several feet over the past decade in many locations, with the steepest declines in zones closest to municipal well fields.

Firestone's response has been to lean more heavily on the C-BT surface-water portion of the portfolio and use groundwater more conservatively. That approach manages the aquifer drawdown but increases dependence on the C-BT system's annual allocation — which is exactly what gets cut during low-snowpack years like 2026. The structural tension between protecting groundwater and depending on snowpack is a defining feature of Carbon Valley water planning.

HOA and brown lawn protections

Colorado Revised Statutes § 37-60-126 protects homeowners from HOA enforcement actions for compliance with declared water-conservation measures. The statute applies in every Firestone master-planned community.

Firestone's HOA-governed neighborhoods — Barefoot Lakes, Booth Farms, Saddleback, and others — historically maintained landscape standards built around irrigated bluegrass. Stage 1 has accelerated revision of those standards toward more drought-tolerant designs in many associations. The statute applies regardless of whether the HOA has updated its design guidelines.

Sample HOA response:

"Dear [HOA Architectural Review Committee], the Town of Firestone and Firestone Utilities have declared Stage 1 Mandatory Water Restrictions limiting outdoor irrigation to two days per week. My lawn reflects compliance with that declaration. Under Colorado Revised Statutes § 37-60-126, the Association may not enforce covenants requiring irrigation inconsistent with the utility's water-conservation measures. Please withdraw the violation. Sincerely, [Your name]"

Keeping your lawn alive on restricted water

Firestone lies in USDA Hardiness Zone 5a/5b. Common turf and landscape options:

Mow on the high end. Bluegrass mowed at 3.5–4 inches retains moisture better than at 2 inches.

Consider buffalograss for new yards. Carbon Valley's combination of declining groundwater and snowpack risk makes buffalograss a practical choice for new homes — it establishes well, needs roughly half the water of bluegrass, and tolerates the area's wind and sun.

Skip summer fertilizer. Fertilizer pushes growth the limited irrigation cannot support.

Mulch beds heavily. Two to three inches of bark mulch dramatically reduces evaporation.

Brown is not dead. Bluegrass goes dormant under heat-and-drought stress and recovers reliably with cooler weather.

Firestone water restriction FAQ

Is Firestone's groundwater running out?

Carbon Valley aquifer levels have declined measurably since the 2010s development boom. Monitoring wells show drops of several feet across the area over the past decade. The town is not running out of water — it is supplementing with C-BT surface water from Northern Water to manage the drawdown — but the long-term trend is real and the structural question of how much growth the aquifer can support is one that Firestone, Frederick, and Dacono are all working through.

What days can I water in Firestone?

Even addresses water Tuesday and Saturday. Odd addresses water Wednesday and Sunday. No watering between 10 a.m. and 6 p.m.

How does Carbon Valley's growth affect water supply?

Population growth has roughly doubled since 2010 across Firestone, Frederick, and Dacono combined. Master-planned communities (Barefoot Lakes, Booth Farms, Saddleback) added thousands of homes with traditional turf-heavy landscaping. The town has expanded both groundwater and C-BT capacity to keep up, but the structural pressure on both sources is real and Stage 1 reinforces the need for permanent demand reduction.

What if I just installed new sod in a new master-planned community lot?

Register with Firestone Utilities for a 21-day establishment variance before installation. The variance allows more frequent watering during the establishment window. After 21 days, the standard schedule applies. Many master-planned community builders coordinate variance registration on behalf of their buyers; ask your builder if it's already been done.

Does Firestone use Denver Water?

No. Firestone is far enough north to be outside Denver Water's service area. The town operates its own utility — Firestone Utilities — sourcing from C-BT via Northern Water and from local groundwater. Denver Water serves the central Denver metro and southern suburbs but does not extend to Carbon Valley.

Can I get a rebate for replacing my lawn with xeriscape?

Firestone offers conservation rebates including smart-controller incentives and turf-conversion programs. Visit the town's utility page or call 303-833-3291 for current program details.

How long will Stage 1 last?

Through at least the 2026 irrigation season. The town reviews status with Northern Water as C-BT allocations and aquifer conditions evolve.

What time can I water in Firestone?

Watering is allowed Not 10am-6pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Firestone?

First offense: Written warning. Repeat violations: Escalating fines. Contact Town of Firestone Utilities for the full enforcement schedule.

When will water restrictions end in Firestone?

Current Stage 1 Mandatory Water Restrictions restrictions are in effect through Until drought conditions improve. Monitor https://www.firestoneco.gov/water for the latest status.

Can I hand water during Firestone water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with Town of Firestone Utilities.

How do I report a water waste violation in Firestone?

Contact Town of Firestone Utilities at 303-833-3291 or visit https://www.firestoneco.gov/water. Most utilities accept online reports and respond within 48 hours.
