Erie is a fast-growing town of about 40,000 people straddling the Boulder-Weld county line between Boulder, Longmont and I-25, with a coal-era main street on Briggs Street and a ring of master-planned neighborhoods built mostly since 2000. It suits buyers who want a newer house with more room than the US 36 towns offer, pools and trails built in, and a short drive to Boulder or Longmont. It suits people less well if they commute to Denver daily, want to avoid metro district taxes, need transit, or are uncomfortable with active oil and gas development nearby.
To explain Erie I have to go back to my childhood. Growing up, Erie meant one thing: the Colorado National Speedway, just across I-25 at Erie's exit. I've been going since elementary school, when it was a dirt track and my father and I would watch the World of Outlaws throw dirt around the oval. It's paved now and still running. Back then there genuinely wasn't much more to Erie: dirt roads, farmland and a racetrack. So a town of 40,000 that has doubled in 15 years is both cool and a little stunning to me.
Erie sits 25 to 30 minutes north of Denver up I-25 and about 20 minutes from Boulder and Longmont. It's a home-rule town in two counties: in the 2020 census, 58% of residents lived on the Weld side and 42% on the Boulder side. The Census Bureau's 2024 estimates ranked it 15th in the nation for growth, up 9.2% in a year, and the town's own count passed 40,000 at the end of 2024.
Most of what's been built is master-planned, with pools, parks and trails designed in and a metro district paying for them. What makes Erie different from other new towns is the thing it didn't have to build: a real coal-town downtown on Briggs Street. People choose it for three reasons I hear over and over: location, how much house you get on a similar budget, and the Colorado lifestyle they picture.
Erie fills the southwest corner of Weld County and spills west into Boulder County, with Broomfield to the south and Lafayette to the southwest. I-25 is the eastern edge at Exit 232, Erie Parkway the east-west spine, US 287 and Highway 7 the west and south frame.
Erie is Old Town plus a ring of planned communities. The ones buyers ask about most:
The original grid around Briggs Street: the oldest homes, smallest lots and most character, and the only part of Erie where you walk to dinner, so you trade square footage for that. The town has run an urban renewal area here since 2013, and in September 2026 its Urban Renewal Authority board approved an agreement for a 13,000-square-foot restaurant and retail building at Briggs and Maxwell, with construction expected to begin in 2027.
Big and family-heavy, with mountain views to the west and an amenity center with a pool. When people picture Erie, this is what they picture, and it has its own social life, events and pools, a town within the town. There's no elementary school in the neighborhood yet: Colliers Hill Elementary (working name Elementary 29) began construction in August 2026 and is scheduled to open in fall 2027. Metro districts approved in 2007 fund the streets, utilities and parks.
I spent a recent afternoon here. Clubhouse, pool, zip lines, climbing towers, kids outside until they're worn out, and a big park you can walk to. One of Erie's more popular neighborhoods, with Highlands Elementary inside it. Two metro districts formed in 2013 run the pool and clubhouse and enforce covenants.
On the eastern edge, closest to I-25, the pick for people who commute to Denver or fly often, with views west. It's a nearly 800-acre Southern Land Company master plan with about 3,000 homes at buildout. It's also closest to the Draco well pad, and an area about 1,500 feet north of the pad was deeded to the St. Vrain Valley School District. Under the town's conditions of approval from March 2025, well completions must finish by Oct. 15, 2027, after which Erie can no longer withhold certificates of occupancy for Westerly Creek homes within 2,000 feet of the pad. Ask before you fall for a lot.
The westernmost neighborhood, closest to Boulder, with the Flatirons filling the view. A 340-acre Hines development of about 690 homes, on the Boulder County side and in Boulder Valley schools, with Meadowlark PK-8 inside the community.
The golf neighborhood, built around Colorado National Golf Club, which opened in 2003 as Vista Ridge Golf Club and is the University of Colorado's home course. My golfers tend to look here, and the Coal Creek Trail ends at Vista Parkway.
Morgan Hill is another metro-district community, with districts dating to 2008. At Erie Parkway and County Line Road, the town bought a 19-acre Town Center parcel in 2022 and in October 2024 approved an agreement setting terms to sell it to developer Evergreen for a planned grocer, hotel, civic space and housing; Erie Four Corners and Erie Commons next door were under construction as of late 2024. Treat the Town Center as a plan, not an amenity.
Same rule as the rest of the metro: know the whole monthly payment, not just the price.
Overwhelmingly single-family and new: the town's end-of-2024 count put about 95% of residents in single-family homes, and 1,195 housing units were added in 2024 alone. Expect two-story and ranch homes from the 2000s through today in the master plans, bigger lots than the US 36 towns, and new construction in phases that are still building out; ask builders what's available. Apartments cluster at Nine Mile Corner; Old Town has the coal-era cottages and infill, and Erie Air Park has hangar homes with taxiway access.
Two districts, and this trips people up. St. Vrain Valley Schools serves most of Erie, including all of the Weld County side: Erie High School (opened 2005, expanded 2018), Erie Middle School downtown, Soaring Heights PK-8, four elementaries with Erie addresses (Black Rock, Erie Elementary, Highlands and Red Hawk) with Colliers Hill Elementary opening in fall 2027, and the Aspen Ridge Preparatory charter.
Boulder Valley School District serves part of the Boulder County side, including Flatiron Meadows, where Meadowlark PK-8 sits inside the neighborhood. People move here counting on Boulder Valley and end up in St. Vrain, which is well regarded; I get good reviews from Erie families. But if a specific school matters, run the exact address through St. Vrain's address lookup or BVSD's School Finder before you write an offer. Colorado has open enrollment, and in St. Vrain it's a space-available decision. And from the people I talk to, Erie has kept pace on schools and facilities better than most towns growing this fast.
The town's 2019 profile counted 58 miles of trails, 17 parks, two reservoirs, a golf course, a velodrome and two singletrack systems. Erie Community Park is the hub: pump track, skate park, ball fields, playgrounds and a sledding hill, if we get snow, with the 63,000-square-foot Community Center beside it. Thomas Reservoir, at 119th and Austin, is a gravel loop of about two-thirds of a mile with the Front Range sitting on the water; it's Colorado, so don't get too excited about the size, but it's a perfect morning with a coffee and the dog. Erie Singletrack is a free mountain bike park on town open space with a view of the whole Front Range. Volunteers built its Sunset West trails; Sunset East, home to the Green, Blue and Black flow lines, was built by hired trail contractors and paid for with community donations. The Coal Creek Trail runs 14 soft-surface miles from Superior through Louisville and Lafayette to Erie.
The Erie Balloon Festival in July, run by the Chamber, hit its 28th year in 2025, and on the right summer morning you'll see balloons lifting off over Thomas Reservoir. I've only managed it once with my daughter, but if you have little kids, giant balloons rising off a lake with mountains behind them means they never want to leave. Good or bad. Erie Biscuit Day in the fall dates to the 1800s, when it marked miners returning to work, and downtown runs a Thursday farmers market in summer.
Briggs Street is a couple of walkable blocks with six or seven good restaurants. 24 Carrot Bistro is where my family goes. The Old Mine is a cidery in an old mercantile, Echo Brewing and Cellar West pour local beer, and there are coffee shops. On a Saturday evening you see families and dogs on the sidewalk and kids playing. New towns can't build that.
Erie is a bedroom community. The town's 2019 profile listed its largest in-town employers as the Town of Erie, King Soopers, Safeway, Lazy Dog and Aspen Ridge Preparatory School, and the average commute was around 26 minutes as of 2024.
The jobs are in the triangle around it. Boulder's largest employers as of 2022 included the University of Colorado, Boulder Community Health and the federal labs, NCAR and NOAA among them. Longmont's as of 2020 included St. Vrain Valley Schools, Seagate, Intrado, two hospitals and the FAA. Broomfield's largest employers as of 2023 included Oracle, Intermountain Health, BAE Systems, Hunter Douglas, Vail Resorts, Crocs and Broadcom. Denver is the long one.
Two myths. First, "Erie is a Boulder suburb." Pretty mythy. Most of Erie is in Weld County, and you're far enough away that if Boulder isn't your vibe, Erie won't feel Boulder-y. Good or bad. Second, "you get more house for your money in Erie." Undoubtedly true, and not just against Boulder: against Lafayette, Superior or Longmont, Erie still gives you a lot more room on a similar budget.
The honest trade is the drive, the metro district and the drilling. If Denver is a daily destination, test the commute. If a pool and a clubhouse matter, the metro district paid for them and you'll pay it back on the tax bill. If active oil and gas nearby is a dealbreaker, say so early; on the east side it's part of the landscape.
My verdict is the one I gave on camera: Erie is space and newness. Don't be scared off by the growth; it's attracting good people and good neighborhoods. I've been fond of this place since I was a kid waiting for the figure-eight cars to wreck into each other, and I look forward to bringing my family up there. Happy to show you around. Maybe we'll catch a race.

Both. In the 2020 census, 58% of residents lived in Weld County and 42% in Boulder County. The county determines which assessor values your home.
Two. St. Vrain Valley Schools serves most of Erie, including Erie High School. Boulder Valley School District serves part of the Boulder County side, including Flatiron Meadows. Check the exact address with the district before you buy.
No. RTD's JUMP bus serves the Erie Community Center on selected trips from Boulder and Lafayette, and the nearest rail is the N Line at Eastlake/124th in Thornton. Most Erie residents drive.
About 25 to 30 minutes to downtown Denver off-peak via I-25, 40 to 45 or more at rush hour. Boulder and Longmont are about 20 minutes, Denver International Airport about 35.
Yes. Weld County is Colorado's top oil and gas producer, and Erie has legacy wells in town. The Draco pad, 26 horizontal wells next to Erie's eastern neighborhoods, was approved by the state in March 2025 over the town's objection; in June 2026 the Town Council voted 4-3 to sell the town's mineral interest to the operator for cash, a revenue share, land and the plugging of 17 old wells.
Most newer ones do. Colliers Hill, Erie Highlands, Morgan Hill, Westerly and other master-planned neighborhoods sit in metro districts that borrowed to build roads, utilities, parks and pools and repay it through an added property tax levy. Old Town is the main exception.
Yes, a small one. Briggs Street in Old Town is a couple of walkable blocks of coal-era brick with restaurants, a cidery, breweries and coffee, smaller than Louisville's or Lafayette's. An agreement for a new restaurant and retail building there was approved in September 2026, with construction expected to begin in 2027, and a separate Erie Town Center is planned at Erie Parkway and County Line Road.
