Site Planning & Design Utah
Civil site plans for Utah residential, commercial and land-development projects—coordinating the property boundary, building layout, grading, drainage, utilities, access, parking and permit documentation into one buildable plan.
A good site plan answers the question: “How does this project
actually fit on this property?”
Ludlow can take a project from the initial boundary and topographic
survey through site layout, grading, drainage, utility design,
permit drawings and construction staking.

Direct answer
What Is a Civil Site Plan?
A civil site plan is an engineered drawing showing how proposed development fits onto a specific parcel of land. It combines the property boundary and existing conditions with the proposed building, setbacks, parking, access, grading, drainage, utilities and other site improvements needed for design, permitting and construction.

Utah Site Planning & Design Services
The scope should match the actual project. A residential building permit does not need the same engineering package as a multi-acre commercial development or subdivision.
Commercial Site Plans
Engineered plans for retail, office, restaurant, industrial and multi-tenant developments including parking, circulation, grading, drainage and utility coordination.
Subdivision Site Design
Lot layout, street concepts, grading, drainage and utility planning coordinated with the survey and subdivision-plat process.
Grading Plans
Existing and proposed contours, finished grades, building-pad elevations, driveway slopes and cut-and-fill concepts.
Drainage Design
Design how runoff moves through and away from the project while protecting buildings, adjoining property, streets and infrastructure.
Utility Coordination
Plan water, sanitary sewer, storm drain and other utility connections around the building layout, grading and existing systems.
Site planning is constraint solving
The Best Building Location Is Not Always the Most Obvious One.
Property lines, setbacks, easements, slope, access, utilities, stormwater and grading can all change what portion of a parcel is realistically buildable. Good site planning identifies those constraints early—before architecture, permitting or construction commits the project to a poor layout.
02 · Existing + proposed conditions
What Goes on a Civil Site Plan?
The exact checklist changes by project and jurisdiction, but these are the major components commonly coordinated in Ludlow's Utah site-plan work.
Property Boundary
Property lines, dimensions, bearings, easements and available survey information establish the legal framework of the site.
Buildings, Contours & Improvements
Existing structures, paving, walls, visible utilities, topography and other relevant physical conditions.
Building Location & Setbacks
The proposed footprint is positioned relative to property lines, required setbacks, easements and other site constraints.
Access, Drives & Parking
Driveways, fire access, parking stalls, accessible spaces, loading and internal circulation where applicable.
Grading & Finished Elevations
Proposed contours, building-pad elevations, slopes, retaining conditions and transitions to surrounding property.
Drainage & Runoff
Surface drainage patterns, stormwater facilities and routing needed to manage runoff from the proposed improvements.
Water, Sewer & Utilities
Existing and proposed utility locations, connections and coordination with the site layout.
Notes, Details & PE Stamp
Applicable engineering notes, construction details and Professional Engineer certification where required by the project.
03 · The site plan becomes the coordination drawing
One Plan Has to Make the Entire Site Work Together.
A building cannot be designed in isolation from the land around it. Moving the footprint can affect driveway slope, utility length, retaining walls, parking, drainage and required setbacks. Changing the grading can affect stormwater routing and adjoining property.
The site-planning stage is where those systems are coordinated before detailed construction proceeds.
Best practice: complete the necessary boundary and
topographic survey before final site engineering. Designing from an
approximate parcel map or assumed elevations can create expensive
redesign later.
04 · Different projects, different site constraints
Projects We Design Site Plans For
The same planning principles apply across project types, but the level of engineering increases as the site, infrastructure and approval requirements become more complex.
New Homes
Building placement, setbacks, driveway, finished-floor elevation, grading, drainage and utility connections.
Additions & ADUs
Fit new construction onto an already developed property while respecting setbacks, access, drainage and existing utilities.
Commercial Buildings
Coordinate the building with parking, accessible routes, vehicle circulation, landscaping, utilities and drainage.
Warehouses & Shops
Large building pads, truck circulation, loading, parking, yard areas, drainage and utility service.
Subdivisions
Coordinate lot layout, streets, grading, stormwater and utilities with preliminary and final platting.
Municipal & Community Projects
Site layout and civil design for facilities requiring coordinated access, grading, drainage and public infrastructure.
05 · Survey first, design second
The Site Plan Is Only as Reliable as the Base Information Under It.
For many projects, Ludlow begins with boundary and topographic surveying. The boundary tells the engineer where the site legally begins and ends. Topography shows how the ground actually slopes and where existing improvements and drainage features are located.
Boundary survey:
establishes reliable property lines, corners and legal site limits.
Topographic survey:
provides contours, spot elevations and existing-condition mapping.
Existing utilities:
help establish feasible connection points and potential conflicts.
Easements:
can restrict building placement, access or utility design.
Survey + engineering:
Ludlow can keep both phases inside one coordinated project team.
Feasibility Comes Before Final Engineering.
Before a developer invests in detailed plans, the site can be tested for realistic lot yield, access, grading, utility service and other major constraints.
The Design Eventually Has to Work on the Ground.
Road geometry, lot layout, drainage and utilities move from the site plan into construction drawings and ultimately construction staking.

Often 1–2 weeks4
Final Engineering
Complete detailed grading, drainage, utility and site-plan drawings for the selected design.
Often 2–4 weeks5
Permit Review
Submit the required documents and respond to applicable city or county review comments.
Jurisdiction schedule varies
07 · 2026 Ludlow planning ranges
How Much Does Site Planning Cost in Utah?
Price depends on project type, acreage, jurisdiction, survey requirements, grading complexity, drainage, utilities and the level of permit engineering required.
| Project Type | Typical Scope | Planning Range |
|---|---|---|
| Residential site plan | New home, addition, ADU or similar project on an existing lot | $1,500–$3,500 |
| Small commercial site plan | Generally under 1 acre with one primary building | $3,000–$7,500 |
| Medium commercial site | Approximately 1–5 acres with more extensive parking, grading or utilities | $6,500–$15,000 |
| Large commercial / industrial | 5+ acres or complex grading, stormwater, utilities and circulation | $12,000–$35,000+ |
| Grading & drainage plan | Stand-alone grading or drainage engineering for an existing property | $2,000–$6,500 |
| Subdivision engineering | Lot layout, streets, utilities, drainage and plat coordination | Quoted by scope |
| Additional permit revisions | Scope beyond included review rounds or material owner-directed changes | Included or hourly by proposal |
Boundary and topographic surveys may be separate from the engineering fee when new survey work is required. Ludlow can quote the survey and site-design phases together so the full project scope is clear before work begins.
08 · Permit-ready civil drawings
Site Plans for Utah Building & Development Review
Many Utah residential projects and most substantial commercial development projects require a site plan as part of local review. The exact checklist varies by city, county and project type.
Instead of using one generic plan everywhere, Ludlow designs the drawing package around the site and the jurisdictional requirements that apply to that project.
Common Review Items
Property dimensions and setbacks
Existing and proposed buildings
Grading and finished-floor elevations
Drainage and stormwater
Water and sewer connections
Parking and accessible spaces
Driveway and fire access
Easements and rights-of-way
Erosion-control information where required
Professional Engineer stamp where required

Site Planning vs. Civil Engineering vs. Land-Use Planning
These services overlap, but they answer different questions. Separating them early helps keep both the design process and the Ludlow site architecture clear.
Site Planning & Design
Answers: Where do the building, parking, access, grading, drainage and utilities go on this specific property?
Civil Engineering
Covers the deeper engineering behind grading, drainage, roads, water, sewer, stormwater, infrastructure and land development.
Land-Use Planning
Addresses whether a proposed use, density or development pattern is permitted and what entitlement, rezoning or planning approval may be required.
From paper back to the ground
Survey → Site Plan → Civil Design → Construction Staking.
Ludlow can carry the same project information from the original property survey through engineered site design and into construction staking. Keeping the phases coordinated reduces handoff problems and gives the field crew a direct connection to the approved design.

Utah Site Planning FAQ
Common questions from homeowners, builders, commercial owners and developers preparing a Utah property for design and permitting.
How much does a site plan cost in Utah?
Ludlow residential site plans generally plan around $1,500–$3,500. Small commercial projects commonly run $3,000–$7,500, while medium commercial sites may run $6,500–$15,000 and large or complex developments can exceed $12,000.
What is included in a civil site plan?
Depending on scope, a site plan can include the property boundary, existing conditions, proposed building, setbacks, access, parking, grading, drainage, utilities, easements and the engineering notes or details required for review.
Do I need a survey before a site plan?
Many projects do. A current boundary establishes the legal site limits, while a topographic survey provides the elevations and existing conditions needed for grading and drainage design.
Do I need a topographic survey?
Topographic surveying is especially important where the project involves new buildings, significant grade changes, drainage, retaining walls, road or driveway design, commercial development or subdivision engineering.
How long does a residential site plan take?
Many straightforward residential site plans can be designed in roughly two to four weeks once the required survey and existing site information are available.
How long does a commercial site plan take?
A typical commercial design may require approximately four to eight weeks before jurisdictional plan review, depending on site size, survey availability, grading, drainage and utility complexity.
Does a site plan need an engineer's stamp?
That depends on the project and local requirements. Significant commercial, grading, drainage and civil engineering work commonly requires drawings prepared and stamped by a Utah-licensed Professional Engineer.
Can Ludlow do the land survey and site plan?
Yes. Ludlow has Professional Land Surveyors and Professional Engineers, allowing the same firm to coordinate boundary and topographic survey work with the subsequent site engineering.
Can Ludlow design the grading and drainage?
Yes. Grading and drainage are core parts of Ludlow's site-planning and civil-engineering work when included in the project scope.
Can you design a subdivision?
Yes. Ludlow provides surveying, lot layout, subdivision platting, roads, grading, drainage, utility engineering and construction staking for Utah subdivision projects.
What should I send for a site-plan quote?
Send the property address or parcel number, city or county, a description of the proposed development, any architectural plans or sketches, available survey information and your project deadline.
Does Ludlow help with permit-review comments?
Yes. Where included in the proposal, Ludlow can respond to engineering and site-plan review comments and revise the plan package as required through the review process.
