From our Nephi office, our civil engineering team mobilizes across both states. Distance to outlying counties is reflected in every quote up front — never a surprise on the final invoice.
Utah Civil Engineering
Statewide civil engineering across Utah’s 29 counties. Our home state and where most of our project history lives. Decades of working relationships with Utah municipalities, county engineers, and building departments — which translates to fewer plan-check surprises and faster permit approvals.
- Wasatch Front: Salt Lake, Utah, Davis, Weber counties
- Central Utah: Juab, Sanpete, Sevier, Millard counties
- Mountain West: Wasatch, Summit, Carbon, Duchesne counties
- Southern Utah: Iron, Washington, Garfield, San Juan counties
Wyoming Civil Engineering
Statewide civil engineering across Wyoming. Our crews travel from Nephi to Wyoming projects regularly — including land development engineering for residential and commercial sites, drainage and stormwater work, site engineering, and engineered design for Wyoming counties and municipalities.
- Southwest Wyoming: Uinta, Lincoln, Sweetwater counties
- Central Wyoming: Sublette, Fremont, Carbon counties
- Northwest Wyoming: Teton, Park, Big Horn counties
- Eastern Wyoming: Laramie, Albany, Goshen counties
Most Wyoming work originates from our long-standing Utah client base — developers, builders, and landowners with projects that cross the state line.
Land Development Engineering
Land development engineering is the engineering work that turns raw land into a permitted, buildable site. It’s the discipline that brings together everything else — feasibility, grading, drainage, utilities, road design, and the documentation that gets the project through plan check.
Most land development engineering projects we work on across Utah and Wyoming follow the same overall sequence: feasibility study, schematic site plan, preliminary engineering, detailed engineering, agency submittals, and construction observation. We act as the engineer of record from start to finish — so the same firm that scoped the project sees it through permitting.
Land Development Engineering Firms — How We Compare
Most land development engineering firms in Utah and Wyoming fall into one of two camps: large multi-state firms with high overhead and slow turnaround, or one-person shops with capacity limits. Ludlow Engineering sits in between — we’re large enough to handle full subdivision projects and small enough that the engineer who quoted your project is the one designing it.
What Land Development Engineering Includes
- Site feasibility and yield studies — what can be built, where, and how many units
- Conceptual and preliminary site plans
- Grading design — cut/fill balancing, finished grades, slope analysis
- Drainage and stormwater design
- Utility design — water, sewer, storm
- Road and access design
- Erosion and sediment control plans
- Construction documents stamped by a licensed Professional Engineer
- Plan-check response and revisions until approval
- Construction observation as the project gets built
Drainage Engineering
Drainage engineering is one of the most common requirements on new construction projects across Utah and Wyoming. Almost every county and city in the region requires a drainage plan — even for small residential additions on lots with slope.
Our drainage engineers design site drainage that meets local code, handles the rainfall events specified by the local jurisdiction, and integrates cleanly with the broader civil site design. The deliverable is typically a stamped drainage plan with calculations attached — which is what building departments actually approve.
Common Drainage Engineering Projects
- Site drainage plans for new residential and commercial construction
- Grading plans that route stormwater away from buildings and foundations
- Detention and retention pond design
- Swale design and channel sizing
- Drainage reports for subdivision approval
- Onsite/offsite drainage analysis for permit applications
- Drainage corrections on existing problem sites
Stormwater Engineering
Stormwater engineering is the regulatory-compliance arm of drainage engineering. For any construction project that disturbs more than one acre, federal regulations (Clean Water Act, NPDES) require a Stormwater Pollution Prevention Plan (SWPPP) and ongoing inspections during construction.
Both Utah and Wyoming delegate enforcement of NPDES construction permits to the state Department of Environmental Quality. The requirements look similar between the two states, but the specific permit forms, fees, and inspector expectations differ — knowing the difference matters. We’ve prepared SWPPPs and managed inspections under both regulatory regimes since the permits were first required.
Stormwater Engineering Deliverables
- SWPPP (Stormwater Pollution Prevention Plan) preparation
- NPDES Construction General Permit (CGP) application
- Best Management Practice (BMP) design and specification
- Construction stormwater inspection scheduling
- Post-construction stormwater control design
- Drainage reports and runoff calculations
- Detention/retention basin design
Subdivision Design & Engineering
Subdivision engineering takes a parcel of land and turns it into a recorded subdivision plat — multiple legal lots, dedicated streets, and the infrastructure needed to support them. It’s the most documentation-heavy work civil engineers do, because every utility, every road, every drainage feature has to be designed, engineered, reviewed, and approved before lots can be sold.
Our subdivision engineering work in Utah and Wyoming covers the full sequence: preliminary plat, preliminary engineering, final plat, final engineering, agency approvals, construction documents, and construction observation. We work with developers, county engineers, and city planning departments to keep the project moving without surprises.
What Subdivision Design Includes
- Preliminary site plan and yield study
- Lot layout and dimensioning
- Road design — alignment, geometry, intersections
- Sanitary sewer collection design
- Water distribution design
- Storm drain design and detention
- Grading and erosion control
- Preliminary and final plat documents
- Construction documents and specifications
- County and city approval coordination
Small Water & Sewer System Engineering
Rural Utah and Wyoming properties often need water and sewer engineering that wouldn’t be required in a city setting — well proofs, septic system design, small public water systems, and small community sewer systems. We’ve designed these systems for rural Mountain West projects since the firm was founded in 1975, and the work remains one of our specialties.
Typical small water and sewer engineering projects:
- Well proofs for property transfers and lender requirements
- Onsite wastewater (septic) system design
- Small public water system design and approval
- Small community sewer design
- Water rights documentation support
- Pumping system design and well analysis
Why Choose Ludlow Engineering for Civil Engineering Work
A few reasons clients across Utah and Wyoming keep coming back:
- Family-owned since 1975. Second-generation Ludlows running the firm. The same engineers and surveyors stay on staff for decades. The same drafter who started your project finishes it.
- In-house everything. Civil engineers, drafters, and licensed land surveyors all under one roof. No subcontracting the engineering work to a separate firm and waiting for them to coordinate.
- Two-state familiarity. Licensed and actively working in both Utah and Wyoming. Familiar with the regulatory differences, jurisdictional preferences, and the specific quirks of agencies on both sides of the state line.
- Fixed-fee quotes. Every project is quoted in writing with the scope attached. No hourly billing creep, no surprise charges at the end.
- Rural Mountain West expertise. Most Utah and Wyoming civil engineering work involves rural sites — well proofs, septic, dirt-road access, and small-system water/sewer. We’ve done thousands of them.
Our Civil Engineering Process
Every civil engineering project follows the same general phases. The specific timeline depends on size, complexity, and which agencies need to review it.
Scoping & Feasibility
We meet with you (in person or by phone), review the site, and assess what’s actually possible — zoning, soils, slope, access, utilities, and regulatory hurdles. Output is a feasibility memo and a fixed-fee proposal.
Survey & Site Data
We collect the site data the engineering work requires — typically a boundary survey, topographic survey, and soils information. Our in-house survey crews handle this without subcontracting.
Preliminary Engineering
Schematic site plans, preliminary grading and drainage, conceptual utility layouts. We share drafts for your review and iterate until the concept is right.
Final Engineering & Construction Documents
Detailed engineering across all disciplines — grading, drainage, utilities, paving, erosion control. Construction documents stamped by a licensed Professional Engineer.
Permitting & Plan Check
We submit to the relevant Utah or Wyoming agencies and respond to plan-check comments until approved. You’re not abandoned at the permit counter.
Construction Observation
Periodic site visits during construction to verify the work matches the engineered design. Documentation for final certification and as-built records.

Frequently Asked Questions
Do you actually work in Wyoming?
Yes. Our civil engineering team works statewide across Wyoming — most projects originate from existing Utah clients with land or development interests across the state line, but we also take on direct Wyoming work. Our crews travel from our Nephi, Utah headquarters. Distance to outlying Wyoming counties is reflected in every quote up front.
What civil engineering services do you provide in Wyoming?
Most of our Wyoming work is civil engineering — land development engineering, drainage design, stormwater engineering, site engineering, and subdivision design. Our Wyoming caseload is more weighted toward civil engineering than the survey side of our practice; for survey-only Wyoming work, call us and we’ll help you find the right firm if it’s outside our active capacity.
How are Wyoming projects priced differently from Utah projects?
Civil engineering rates are the same regardless of which state the project is in. The only price difference is mobilization — Wyoming projects in the southwestern part of the state (Evanston, Star Valley) are essentially the same as central Utah from a travel standpoint, while projects in the northeast (Cheyenne, Laramie) require more crew time on the road. We disclose travel costs in every quote so there are no surprises.
What is land development engineering?
Land development engineering is the engineering work that turns raw land into a permitted, buildable site. It includes feasibility studies, grading design, drainage, utilities, road design, and the engineered documentation county and state agencies require for approval. It’s typically the work that comes between a land purchase and the start of construction.
Do you handle drainage engineering for residential projects?
Yes. Most Utah and Wyoming counties require drainage plans for new residential construction — even single-family homes on sloped lots. We provide drainage design, grading plans, and the stamped engineered drawings building departments accept.
What’s the difference between drainage engineering and stormwater engineering?
Drainage engineering is the broader discipline of moving water across a site safely. Stormwater engineering is the regulatory-compliance subset — specifically the SWPPP, NPDES permit, and BMP work required when a project disturbs more than one acre. Most projects need both; the documentation requirements differ.
Do you work with developers on subdivisions in both states?
Yes. Subdivision design is one of our core specialties — we’ve designed dozens of subdivisions across Utah and Wyoming since 1975. Full-service subdivision engineering includes preliminary plat, preliminary engineering, final plat, construction documents, and agency approvals.
How long does a typical civil engineering project take?
It depends on size and agency review timeline. A small site engineering project (residential drainage, small grading plan) typically runs 4–8 weeks total. A full land development project (subdivision design, multiple agency approvals) often runs 6–12 months. Plan-check time at the agency is often the longest single phase — outside our control.
Are you licensed in both Utah and Wyoming?
Yes. Our Professional Engineers hold active licenses in both states. Wyoming professional engineering licenses are issued by the Wyoming Board of Professional Engineers and Professional Land Surveyors; Utah licenses are issued by the Division of Occupational and Professional Licensing.
Can you handle a project that spans the Utah-Wyoming state line?
Yes. Cross-state projects are a regular part of our work — particularly in the southwestern Wyoming / northeastern Utah corridor where rural ranching and development properties straddle the state line. Having engineers and surveyors licensed in both states under one roof eliminates the coordination headaches of working with two separate firms.
Do you provide construction observation?
Yes. Most civil engineering projects benefit from periodic construction observation by the engineer of record. We make periodic site visits, verify the work matches the engineered design, and produce documentation for final certification and as-built records. Construction observation is usually billed separately from the design fee.
How fast can I get a quote?
Most basic quotes go out within 2–3 hours of receiving your project information. Larger or more complex civil engineering projects that require additional research, agency consultation, or a preliminary feasibility look may take 1–2 business days. Either way, the quote is fixed-fee, in writing, with scope of work attached.
