Freeway-frontage pads along I-25 only pay off when the site work is finished before the building is, and that is the sequence we run in Johnstown: mass grading, detention, utilities and interchange-driven access first, then the shell. The Ridge at Johnstown is a 265-acre master-planned mixed-use site at 6424 East County Road 18 with 90 acres of I-25 frontage, access through the Highway 402 interchange and about 100,000 vehicles per day of freeway visibility; 122 acres had been sold to residential developers. For an industrial or commercial owner, that mix of freeway visibility and residential growth sets expectations for how the building looks, how trucks are screened and how the site meets its neighbors.
We build warehouse, flex and service buildings in the I-25 corridor with those expectations in mind, planning truck courts away from the frontage where possible, screening dock sides, and designing detention basins that read as part of the landscape rather than as a hole in the ground. Our work for logistics and distribution owners on this kind of corridor is where those decisions pay back, because a screened, well-organized yard leases and operates better than one that sits in full view of the interstate.
Between Greeley, Loveland and the interstate
Johnstown is a home rule municipality in Weld and Larimer counties at about 4,994 ft elevation, with Greeley about ten miles east-northeast and Loveland about nine miles northwest; its population grew from 9,887 in 2010 to 17,303 in 2020. State Highway 56 is 9.5 miles long and runs from US 287 in Berthoud east to I-25 exit 250 and US 87 in Johnstown. Those distances put a Johnstown building within reach of two labor markets and two regional highways, and the I-25 exit gives access north and south without passing through a downtown.
When a project spans more than one of those places, we price them on equal terms: Greeley for heavier process users and Berthoud for smaller shops along State Highway 56. The comparison covers access, utilities, soil and review path, not only land price.
Site first: grading, utilities and access
On a greenfield parcel with freeway frontage, the building is the smaller part of the work. We start with site clearing and mass grading that balances cut and fill on site where possible, and then install storm, sanitary, water and fire-line infrastructure before the building pad is released. Compaction testing and survey records for each pad are given to the owner and the structural engineer so the foundation design rests on documented ground.
Access is the item most often underestimated. An interchange-driven site may require turn lanes, signals or right-of-way dedication, and those approvals take time. We start the access discussions with the town and state at the beginning of design, not at the end, and include their timeline in the schedule.
Retail, flex and distribution on one corridor
A 2022 report described a Highway 60 and I-25 project in Johnstown planned for more than 1,000 housing units and more than 1 million sq ft of retail with Murdoch's committed, at an interchange passing more than 99,000 vehicles daily. Residential and retail growth at that scale generates demand for the service, supply and delivery businesses that support it. We build retail shells alongside light-industrial and distribution center buildings so that a mixed project is delivered under one schedule.
Because plans for large mixed-use areas change, we price what is approved and keep expansion options in the design. A distribution building can be laid out with a longer side that allows adding bays later, and the utilities can be sized for that expansion.
Traffic, trucks and interstate-adjacent work
Construction beside an interstate interchange requires traffic control, truck routing and care with dust and debris. We prepare a traffic control plan, locate the construction entrance away from the ramps and keep the road clear with sweeping and wheel washing. Crane operations and tilt-panel lifts are positioned so that no boom swings over the road.
Fire protection is installed early. We construct fire water loops and hydrant systems so the fire department has water and access during construction, and the system is tested and accepted before the building is enclosed.
A town on a county line
Johnstown lies in both Weld and Larimer counties. Commercial building codes in Colorado are adopted city by city and county by county rather than as one statewide code, so an owner here should confirm which jurisdiction reviews a parcel and which edition applies. Unincorporated Weld County adopted the 2024 International Building Code effective June 15, 2026, with engineered foundation designs required for most new structures, but town parcels follow the town's own adoption.
We confirm the code basis with the town before we price, write it into the proposal and ask how the town treats projects that are submitted close to an adoption date. Our permitting and entitlements coordination gathers the site, access, drainage and building reviews into one tracked schedule.
Send the parcel and the access plan
Send the parcel, the concept plan and any traffic study. We will return a site and utility scope, an access approval schedule and a building plan for the first phase.
Common Questions
What is The Ridge at Johnstown?
It is a 265-acre master-planned mixed-use site at 6424 East County Road 18 with 90 acres of I-25 frontage and access through the Highway 402 interchange. About 122 acres had been sold to residential developers. We treat it as an indicator of the corridor, not as a project of ours.
Which highways serve Johnstown?
I-25 serves the town with an interchange at exit 250 where State Highway 56 meets US 87, and State Highway 56 runs 9.5 miles west to US 287 in Berthoud. Highway 60 also meets I-25 in the area.
Which building code applies?
Johnstown lies in both Weld and Larimer counties, and codes are adopted locally. Unincorporated Weld County adopted the 2024 International Building Code effective June 15, 2026, but a parcel in town follows the town's adoption. We confirm before pricing.
How do you manage access permits at an interchange?
We open the access review with the town and state early, plan for turn lanes or signals and place the approval dates on the critical path.
Can you build retail and industrial space on the same site?
Yes. We coordinate separate building permits under a single site plan, with shared utilities, detention and access, and we separate truck routes from customer parking.
What does it cost to build detention that looks like part of the landscape?
Usually little more than a standard basin if it is planned from the start. We shape side slopes, set the outlet and spillway for the required volume and let the civil engineer and landscape designer share the layout. Retrofitting a basin after the site is graded costs much more, so we settle it with the grading plan.
