Commercial Site Development Engineering in Central Utah.
Survey, grading, drainage, utilities, access and approvals for commercial sites, from due diligence to the final as-built, by one firm. 142 site plans in our records, from restaurant lots and RV parks in Nephi to apartment sites in Fillmore.
The short version
What Does Commercial Site Development Engineering Include?
Every commercial site needs the same core pieces: a boundary and topographic survey; a grading plan that moves water away from the building; a stormwater design that meets city and state rules; water, sewer or septic, and power coordination; safe access, parking and fire lanes; and a stamped plan set that the jurisdiction approves.
In central Utah, rural conditions such as state highway frontage, wells and septic, and smaller review boards shape how those pieces come together.

01 · The process
Five Phases of a Commercial Site Project
From the first look at a parcel to the certificate of occupancy.
Due diligence
Zoning, access, utilities and a feasibility layout.
Survey
Boundary or ALTA plus topography of the site.
Design
Grading, drainage, utilities, access and parking.
Approvals
City or county review, plus any state permits.
Construction
Staking, inspection support and as-builts.
02 · What we design
The Engineering Behind a Commercial Site
Every item below appears on the stamped plan set your jurisdiction reviews.
Drainage & stormwater
Storm drains, detention or retention, and erosion control that meet city and state requirements. Civil engineering.
Utility design
Water, sewer or onsite wastewater, and coordination with power, gas and communications. Water & sewer design.
Driveways & circulation
Entrances, truck turning, fire access and coordination with UDOT on state routes.
Survey base
Boundary or ALTA and topography, so design starts from accurate ground. Topographic surveys.
Staking & as-builts
Layout for the contractor and final as-builts for city sign-off. Construction staking.
Design starts with accurate ground. Because our surveyors and engineers work together, the topography and boundary go straight into the grading and utility design, and the same team stakes the site when construction starts.
03 · Central Utah specifics
What’s Different About Developing in Central Utah
Rural and small-town sites raise questions that urban projects often don’t.
State route frontage
Many sites front I-15 interchanges, US-89 or US-6, where UDOT access permits apply.
Wells & septic
Sites without city services need water supply and onsite wastewater approved by the local health department.
Water rights & connections
Confirm water rights or connection availability early; it can drive the whole schedule.
One-acre threshold
Disturbing an acre or more generally triggers Utah UPDES construction stormwater permitting.
Farm-to-commercial conversion
Rezoning or conditional use approval may be needed on former agricultural land.
Small-town review boards
Planning commissions meet less often, so submittal timing matters.
04 · Before you close
A Due Diligence Checklist for Commercial Land
These questions decide whether a parcel works for your building, and what it will cost to get there.
- Zoning: is your use allowed, conditional or a rezone?
- Access: city street or state route, and where can driveways go?
- Utilities: water, sewer, power and gas at the property line?
- Drainage: where does water go now, and where must it go?
- Title: easements and encroachments from an ALTA survey.
- Flood zone: any mapped floodplain on the parcel.

Commercial Site Development FAQ
What is commercial site development engineering?
It's the civil engineering that turns a parcel into a buildable commercial site: grading, drainage and stormwater, utilities, access and parking, all shown on a stamped site plan set that the city or county approves before construction.
When should I bring in a civil engineer?
Before you buy, if possible. A quick feasibility review of access, utilities, zoning and drainage can reveal costs that change the deal. At minimum, bring us in before the architect fixes the building footprint.
Do I need a stormwater permit for my commercial site?
In Utah, construction that disturbs one acre or more generally needs coverage under the state's UPDES Construction General Permit and a stormwater pollution prevention plan (SWPPP). Many cities also have their own stormwater requirements for smaller sites.
What if my site fronts a state highway?
New or changed access to a state route usually needs a UDOT access permit, which can affect driveway location, turn lanes and timing. We plan for it early in design.
What if there's no city sewer or water?
Rural commercial sites may need a well or water connection and an onsite wastewater system approved by the local health department. Those systems shape the site layout, so we design around them from the start.
How long does commercial site design and approval take?
It depends on the size of the project and the jurisdiction's review schedule. Smaller central Utah sites can move from survey to approved plans in a few months; larger sites with state permits take longer.
What does a commercial site plan cost?
Small commercial site plans typically run $3,000–$7,500, medium sites $6,500–$15,000, and large sites $12,000–$35,000+. Grading and drainage plans run $2,000–$6,500. Every proposal is a fixed fee in writing.
Do you provide the survey too?
Yes. Our surveyors handle the boundary, ALTA and topographic surveys, then construction staking and as-builts, so design is based on our own data.
What areas do you serve?
Central Utah from our Nephi office: Juab, Sanpete, Millard, Sevier and south Utah County, plus projects elsewhere in Utah by request.
