Land Development Infrastructure in Casper, Wyoming

Mills grew from 3,461 residents in 2010 to 4,034 in the 2020 census, and Bar Nunn grew about 35 percent over the same ten years. Growth like that does not arrive as buildings. It arrives as lots, and every lot needs a street, a water service, a sewer connection, storm drainage and fiber before anyone can build on it.

Land development infrastructure is that bundle of work: mass grading, utilities, curb and street, drainage and the erosion controls that go with them. The deliverable is a set of finished lots that a builder can pull a permit for. The developer's margin depends on how quickly and cheaply that happens, so we plan the sequence around lot delivery, not around our own convenience.

We work for commercial developers, residential developers and public agencies. Our scope can be a single utility extension or a whole subdivision from clearing to final acceptance.

What growth in the metro asks for

The Casper metropolitan area includes towns that are small on their own and large together. Mills has franchise agreements with several telecom providers to build fiber networks, and its public works department runs a water treatment facility. In the airport area, the Wyoming Business Council approved $617,483 in grant funding for roughly 30,000 linear feet of fiber optic cable in and around the business park. Both facts point the same direction: new development needs fiber in the ground beside the water and sewer.

We coordinate with each town's public works department and with the utility owners. The construction trade partners in Mills and Bar Nunn know that each jurisdiction has its own standards, plan reviewers and inspection habits. That local knowledge shortens the learning curve for every phase.

The full package

A typical package starts with clearing and topsoil stripping, then mass grading to the street and lot grades. Utilities follow: water mains, sanitary sewers, storm drains and dry utilities in joint trench. Street subgrade and base go in after the trenches are tested and backfilled, then curb, gutter and paving.

Detention or retention facilities are built early, so they can serve as sediment traps. Erosion controls go in before the first cut and stay until the final stabilization. At the end, we complete the punch list, file as-builts and walk the inspectors through for final acceptance.

Approvals that gate the work

Casper commercial permits often require a life-safety plan, engineered drawings and planning and zoning approval, and an issued permit is good for 180 days. Subdivision work usually involves plan approval from the city or town, utility owner approval and a stormwater permit. Each approval has its own timing, and a late approval can idle a crew.

The City of Casper's industrial revenue bond policy, adopted by City Council on December 16, 2025, considers bonds only for projects over $2 million that create employment, expand the tax base and promote Wyoming products, with committee review taking about two months. Developers who plan to use that tool should start the application early, because site work often waits for financing decisions.

What we manage as one scope

We coordinate the earthwork, trenching, pipe installation and subgrade preparation that make up the largest part of a development contract. Keeping those trades under one contract means one schedule, one superintendent and one safety program. When the utility crew is ready, the earthwork crew has already finished the grade.

Specialty items, such as fiber pulling, electrical gear and landscaping, are coordinated with the owners and their contractors. We provide the trenches, conduit and compacted backfill they need. The coordination matters as much as the digging, because a trench closed before the fiber crew arrives costs money to reopen.

Phasing lots to meet builders

Developers sell lots in phases. We phase the work so each section is complete and accepted before the builder arrives. That means finishing the utilities, the road base and the curb first, and leaving the top lift of paving for after builders' heavy traffic. A temporary construction entrance protects finished streets.

Season is the other constraint. We aim to do earthwork and utilities in the warm months and to leave final paving for the first stable weather. Winter shutdown plans protect open trenches and stockpiles. If a phase has to run into the cold, we price cold-weather protection openly and explain what it buys.

What moves a development budget

The largest items are earthwork, underground utilities and paving. Within them, the swing factors are the soil conditions, the depth of the utilities, the length of the streets and the number of lots per acre. Compact lot layouts reduce street and pipe length per lot, while large lots stretch them.

We give unit prices for each element so the developer can compare layouts. For a multifamily or mixed-use project, we also price the phasing, since buildings often start before streets finish.

Developers and agencies we work for

The calls come from commercial developers planning business parks, from homebuilders and multifamily developers who need finished lots, and from public agencies extending service. Each buyer has a different appetite for risk and a different way of paying. We adapt the contract format, but not the standards.

The sequence of money matters as much as the sequence of work. A developer who sells lots in phases wants infrastructure costs spread to match, and a public agency wants unit prices it can audit. We break the work into bid items that follow the plat: grading by phase, each utility by footage, streets by block. That structure makes pay applications easy to check and change orders easy to price when a conflict turns up in the ground. Where an owner is pursuing financing, we also give the lender a schedule of values that matches the draw requests.

Send the plat and the utility plan

We will price the grading, the underground and the street package as separate items, give you a sequence that gets lots to final grade and tell you which approvals gate each phase.

Questions Owners Ask

Can you build a subdivision in phases?

Yes, and phased work is normal. Each phase has its own grading, utilities and streets. We build it so the completed phase works on its own: it drains, is accessible and meets the city's acceptance requirements.

Who coordinates the utility companies?

The developer or the engineer usually leads, and we support with schedules, locates and joint trenches. We talk to the gas, power and fiber owners early to prevent conflicts in the trench.

What approvals do we need before work starts?

Plan approval from the city or town, a stormwater permit and utility owner approvals. Some projects need zoning actions. We list the approvals we need in our proposal.

How long does a typical development take?

A small commercial park may take a season. A multi-phase subdivision can take two or more. Approvals, weather and utility lead times are the main variables.

Do you provide as-built drawings?

Yes. We record the location, depth and elevation of every utility as it is installed, and we give the engineer the survey for the as-builts. Cities need these for acceptance.
