A town that spans the Weld and Boulder county line puts extra work on the survey, the drainage study and the utility records before a single footing is dug, and we build that work into the front of every Erie project. At the 2020 census, 17,387 residents (58 percent) lived in Weld County and 12,651 (42 percent) in Boulder County, so an industrial owner here may find that records, special districts and neighboring parcels sit under different county files. We resolve those questions in preconstruction so the building permit set describes one site clearly.
Erie is also positioned for owners who need highway and air access in a small package. I-25 runs along the eastern edge with Exit 232 serving the town, E-470 lies to the south, and State Highways 7 and 52 and U.S. 287 on the west also serve the area. We build flex and light-industrial space, contractor facilities and storage buildings that make use of that network, and we plan truck courts, entrances and detention basins for the delivery vehicles the tenant actually runs.
Flex, storage and aviation-adjacent buildings
Erie Municipal Airport (EIK) is town-owned and operated about three miles west of I-25 on Colorado Highway 7, with a concrete main runway listed as 4,700 feet long. A small public airport changes the mix of buildings an industrial contractor is asked to build: hangars, aviation-service shops, equipment storage and flex units for companies that want to be near the field. We build aircraft hangars with clear-span framing, large door openings and slab designs for the aircraft and ground equipment the owner expects.
Door size drives the structure: a wide hangar door needs a stiff header and a defined load path, and the slab edge at the door needs to resist repeated wheel loads. We design those details with the owner and the structural engineer before ordering the building package, and we verify airport height and setback limits with the town before design is final.
Flood history and the drainage problem
Major floods hit the Erie area in 1890, 1921 and 1972, and after the 1972 flood a dike was built around nearby Coal Creek. The record is a good reason to check floodplain and drainage conditions before a site is purchased, because creek corridors in this part of the county can influence pad elevation, outfall locations and downstream capacity. We ask for the floodplain determination, review the geotechnical report for groundwater and set the building finished floor accordingly.
Our stormwater detention and drainage design is coordinated with the town and any applicable district, and we verify the as-built grades and outlet structure in the field. Where a site drains toward a creek, we also plan erosion control during construction, because a rain event on exposed soil can create downstream complaints and delay inspections.
Costs that tend to separate Erie projects
On a small-town site, utilities and access often cost more than the building. Extending water, sewer and electrical service, building turn lanes at a state highway and constructing a detention basin can equal a large share of the project budget. We price those items early with allowances, because an owner who buys land without knowing the cost of utilities can exceed the pro forma before any steel is ordered.
Foundation costs follow the soil. Front Range clay soils often call for engineered foundations, and unincorporated Weld County, which adopted the 2024 International Building Code effective June 15, 2026, requires engineered foundation designs for most new structures. Even inside town limits, we plan for an engineered foundation and verify the soils through borings before pricing.
2021 IBC today, a decision pending
The Home Builders Association of Metro Denver tracker dated January 20, 2026 lists Erie as enforcing the 2021 IBC, with the town evaluating a mid-2026 move either to the full 2024 I-Codes plus the State Low Energy and Carbon Code or to retaining the 2021 I-Codes plus that state code. The tracker is not an official source, so we verify the status with the building department. An undecided adoption affects any project in design now, and we write the alternative requirements into the code memo for owners to review.
State law under HB22-1362 sets an energy benchmark for jurisdictions that update their codes, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. For a project with a long design phase, that is an important date, and we flag it at the first meeting.
Distribution and service users on the I-25 corridor
Owners who value I-25 access often run distribution, delivery or service businesses, and we serve them with ecommerce fulfillment buildings and smaller warehouses sized to a regional route. These users want an efficient dock layout, enough trailer or van parking and a yard that can expand.
The same site can be planned in phases: a first building now, pad-ready land for a second later, with utilities sized for both. Compare with Firestone or Frederick in the same I-25 corridor and the main differences are the code basis and the jurisdiction, which is why we keep our proposals clear on both.
Send the parcel and the county records
Send the survey, the county or town records and your target use. We will return a drainage and utility allowance, a code memo for the current and proposed editions and a schedule for the permit path.
Common Questions
Does a site in Erie fall under Weld County or Boulder County?
The town lies in both counties, with 58 percent of its 2020 residents in Weld County and 42 percent in Boulder County. We check the parcel's county, special districts and recorded records at the start of the project, and we confirm which jurisdiction processes each approval.
Can you build a hangar near Erie Municipal Airport?
We build hangar structures with clear-span framing, large doors and slabs designed for aircraft loads. Airport height, setback and use rules are confirmed with the town before design is final.
Which building code is Erie using?
A January 20, 2026 tracker from the Home Builders Association of Metro Denver lists the 2021 IBC, with the town evaluating a mid-2026 move to the 2024 I-Codes plus the State Low Energy and Carbon Code, or retaining the 2021 I-Codes plus the state code. We confirm with the building department.
How does flooding history affect design?
Floods in 1890, 1921 and 1972 and the dike built around Coal Creek afterward are reasons to check the floodplain, groundwater and drainage before buying land. We set finished floor elevations and detention design from that review.
What is the biggest cost surprise on small-town industrial sites?
Utilities and access. Extending services, turn lanes and detention basins can take a large share of the budget, so we price allowances for them during preconstruction.
How do you plan a first building so a second can follow?
We size the utilities, the detention basin and the entrance for both buildings, rough in the second pad grading where it saves money and keep the yard layout open for expansion. The first building is permitted and built on its own, so the owner is not paying for the second before it is needed.
