How to Grade and Level a Yard for Proper Drainage (DIY Guide)

By the team at Beehive Rental & Sales — Serving Southern Utah's contractors and homeowners since 1994.

Improper yard grading is one of the most expensive problems a homeowner can ignore. Water that pools against your foundation, saturates your landscaping, or floods your patio did not get there by accident --- it got there because the ground is directing it to the wrong place. Regrading a yard corrects the slope so water moves away from structures and toward appropriate drainage points, protecting your foundation and your investment.

“

Quick Answer: Proper yard grading requires a minimum slope of 1 inch per 8 feet away from your foundation, achieved by stripping topsoil, establishing rough grade with a skid steer or compact track loader, fine grading, and compacting. BeeHive Rental & Sales in St. George rents skid steers with box blades, plate compactors, and laser levels for DIY grading projects. Call (435) 628-6663 for equipment availability.

Key Takeaways

• •Minimum drainage slope is 1 inch per 8 feet (1% grade) away from your foundation --- anything less and water pools against the structure, risking foundation damage over time
• •A skid steer with a box blade is the primary grading tool for residential projects, letting you cut high spots and fill low spots efficiently across your entire yard
• •Southern Utah's desert soil compacts differently than clay-heavy soils in wetter climates --- you need to add water during compaction to achieve proper density in our dry, sandy conditions

Why Yard Grading Matters

Yard grading is not cosmetic. It is structural. The grade of your yard determines where water goes during every rainstorm, every irrigation cycle, and every monsoon season downpour. Get it wrong and you face real, expensive consequences.

Foundation Protection

Water pooling against your foundation is the leading cause of foundation problems in residential construction. In Southern Utah, our expansive soils swell when wet and shrink when dry, creating heaving and settlement cycles that crack foundations. Proper grading moves water away from the foundation before it can saturate the soil.

Landscape Health

Standing water drowns grass, kills plants, and creates mosquito breeding habitat. Most landscape plants --- especially those suited to Southern Utah's climate --- need well-drained soil. Regrading eliminates low spots where water collects.

Erosion Prevention

Without proper grade, water concentrates in uncontrolled paths across your yard, cutting channels and washing away topsoil. This gets worse with each rain event. Proper grading distributes water flow evenly, reducing erosion.

Property Value

A well-graded, properly drained yard is a selling point. A yard with visible drainage problems, standing water, or foundation staining is a red flag that costs thousands in buyer negotiations.

How to Assess Your Current Grade

Before renting equipment and moving dirt, you need to know where you stand. Here is how to assess your existing grade using the string level method.

The String Level Method

1. •Drive a stake against your foundation wall at the highest point of your yard
2. •Drive a second stake 8-10 feet away from the foundation
3. •Tie a string between the stakes at the same height
4. •Use a line level (a small level that clips onto the string) to get the string perfectly level
5. •Measure the distance from the string to the ground at both stakes

The ground at the far stake should be lower than the ground at the foundation stake by at least 1 inch per 8 feet of distance. If the far measurement is the same or higher, your grade is flat or negative --- and water is flowing toward your foundation.

Repeat this process at multiple points around your home to identify the worst areas and establish priorities.

Using a Laser Level

For larger properties or more precise measurements, a laser level (also called a transit or builder's level) provides accurate grade readings across your entire yard. Set up the level at a central point, take a rod reading at the foundation, then take readings at 10-foot intervals moving away. Each reading should show progressively lower elevation.

BeeHive Rental & Sales rents laser levels that make this measurement straightforward even for first-time users.

Equipment You'll Need

Yard grading requires equipment that can move, spread, and compact soil across a large area. Here is the essential equipment list.

Skid Steer with Box Blade (Primary Grading Tool)

A skid steer equipped with a box blade attachment is the most efficient tool for residential yard grading. The box blade cuts high spots, carries material to low spots, and spreads it in controlled, even layers. You can rough grade an average residential yard in a single day with a skid steer.

Alternative: A compact track loader provides the same grading capability with better traction on soft or sandy soil. In Southern Utah, track loaders often outperform wheeled skid steers because our soil tends to be loose and sandy.

Recommended: Bobcat S450 with box blade attachment, or T450 track loader for soft-ground conditions. Available at BeeHive Rental & Sales.

Plate Compactor

After establishing your grade, you need to compact the soil to prevent future settling. A plate compactor delivers consistent compaction force across the graded surface. Without compaction, your carefully established grade will settle unevenly over the first few months, creating new low spots.

Laser Level or Builder's Transit

Accurate grading requires accurate measurement. A laser level lets you establish and verify grade across your entire yard, ensuring consistent slope in the right direction. Trying to grade by eye results in subtle low spots that only reveal themselves during the first heavy rain.

Hand Tools

A landscape rake (the wide, flat-tined type), a shovel, stakes, string, and a tape measure round out your toolkit. The landscape rake handles fine grading after the skid steer establishes rough grade.

Step-by-Step: Grading Your Yard

Step 1: Survey and Mark Your Grade

Before moving any dirt, establish your target grade on paper.

1. •Identify all structures (house, garage, shed, patio) that need positive drainage away from them
2. •Identify your drainage outlets --- where does water ultimately go? (Street, storm drain, drainage swale, dry well)
3. •Set stakes at your foundation and at your target drainage points
4. •Calculate the required elevation change: minimum 1 inch per 8 feet, but 2 inches per 8 feet is better if you have the room

Call 811 before you start. Utility locate is free and legally required before grading work that involves any excavation or soil disturbance.

Step 2: Strip and Stockpile Topsoil

If you have existing landscaping, strip the top 4-6 inches of topsoil and stockpile it to one side. Topsoil is valuable --- you will replace it after establishing your rough grade on the subsoil beneath.

Use the skid steer with a bucket attachment for this step. A box blade is not ideal for stripping --- switch to the bucket, strip the topsoil, then switch back to the box blade for grading.

Step 3: Establish Rough Grade

This is where the skid steer with box blade earns its rental fee.

1. •Start at the foundation (your highest point)
2. •Work outward toward your drainage points (your lowest points)
3. •Cut high spots and push material into low spots
4. •Work in parallel passes, overlapping slightly
5. •Check grade with the laser level every 3-4 passes
6. •Continue until the entire yard slopes consistently from foundation to drainage points

Tip: In Southern Utah, the native subsoil is often quite hard and compact. If your box blade is skating across the surface without cutting, lower the scarifier teeth (the adjustable teeth on the back of the box blade) to break up the surface before making your grading pass.

Step 4: Fine Grade

After rough grading, switch from the skid steer to hand work with a landscape rake.

1. •Walk the entire graded area looking for subtle high and low spots
2. •Rake material from high spots into low spots
3. •Check with the laser level at close intervals (every 4-5 feet)
4. •Fill and smooth any skid steer tracks or depressions

Fine grading takes patience. Spend the time here --- this is the finished product beneath your topsoil.

Step 5: Compact the Subgrade

Run the plate compactor over the entire graded area in overlapping passes.

Southern Utah specific: Our dry desert soil does not compact well when it is bone dry. For proper compaction, you need to add moisture. Lightly water the graded area and let it soak in for 15-20 minutes before compacting. The soil should be damp but not muddy --- think of the consistency of soil after a light rain. Make at least 3 passes with the plate compactor over the entire area.

Step 6: Replace Topsoil

Spread your stockpiled topsoil back over the compacted subgrade in a uniform layer, maintaining the established slope. Use the landscape rake to distribute it evenly.

If you need additional topsoil, order it before your equipment rental starts so it is on-site and ready to spread.

Step 7: Final Compaction and Seeding

Lightly compact the topsoil layer (one pass with the plate compactor or a lawn roller). Seed or sod immediately to prevent erosion of your newly graded surface. In Southern Utah, fall (October-November) or spring (March-April) are the best times for lawn establishment.

Common Grading Mistakes

Grading Toward the Foundation

This sounds obvious, but it happens more often than you would expect --- especially in areas where previous landscaping has built up soil against the house. Always verify slope direction with a level, not by eye.

Insufficient Slope

A slope of 1 inch per 8 feet is the bare minimum. Where practical, aim for 2 inches per 8 feet. Water will find the path of least resistance, and barely-adequate slopes become inadequate slopes after soil settles.

Skipping Compaction

Uncompacted soil settles 10-15% over the following months. Your carefully established grade becomes a collection of random low spots. Compact properly and you avoid regrading the same yard next year.

Ignoring Existing Drainage Patterns

Work with your property's natural drainage patterns, not against them. If water naturally flows to the east side of your yard, grade to guide it efficiently in that direction --- do not try to push it uphill to the west.

Forgetting About Hardscape Transitions

Where your yard meets a driveway, sidewalk, patio, or fence, the grade transition needs to be smooth and maintain proper slope. Abrupt grade changes next to hardscape create channeling and erosion.

Southern Utah Grading Considerations

Desert Soil Compaction

Southern Utah soil is predominantly sandy with rocky inclusions. Unlike clay soils that compact readily, sandy soil requires moisture to achieve density. Always pre-wet before compacting. Without moisture, you are essentially just rolling the top surface while leaving voids beneath.

Drainage Patterns in Red Rock Terrain

Many St. George area neighborhoods are built on terrain that was originally desert wash drainage. Developers grade and redirect these flows, but heavy monsoon rains can overwhelm engineered drainage. Understand where water flowed naturally before development, and avoid grading your yard into the path of these historic drainage patterns.

New Subdivision Grading Issues

Newer subdivisions in the St. George area frequently have grading problems that become apparent within the first 1-2 years as builder-grade grading settles. If you are in a newer neighborhood and noticing pooling water, you are not alone --- this is one of the most common reasons homeowners rent grading equipment from BeeHive Rental & Sales.

Monsoon Season Flooding

Southern Utah's monsoon season (July through September) brings intense, short-duration rainstorms that dump significant water in minutes. Proper grading is your first line of defense against monsoon flooding. Grade your yard before monsoon season, not during it.

Cost Comparison: DIY vs. Hiring Out

For a typical St. George residential yard (3,000-5,000 square feet), DIY grading with rental equipment saves $500-$4,000 compared to professional grading services. The work is straightforward with the right equipment --- no specialized skill is required beyond patience and willingness to check your measurements repeatedly.

FAQ

What slope should a yard have for proper drainage?

The minimum recommended slope is 1 inch of fall per 8 feet of horizontal distance (approximately 1% grade) away from your foundation. A slope of 2 inches per 8 feet (approximately 2% grade) is preferable where site conditions allow. This slope should extend at least 6-10 feet from the foundation before transitioning to a gentler grade across the rest of the yard.

Can I grade my yard without a skid steer?

For small areas (under 500 square feet), you can grade by hand with a landscape rake, shovel, and wheelbarrow. For anything larger, a skid steer with box blade attachment is dramatically more efficient and produces more consistent results. BeeHive Rental & Sales in St. George rents skid steers on daily and weekly rates that make mechanized grading accessible for any budget.

How do I know if my yard has a grading problem?

Common signs include water pooling against your foundation after rain, standing water in the yard more than 24 hours after a storm, erosion channels forming in the yard, damp or wet basement or crawl space walls, and cracks in your foundation. If you see any of these, assess your grade using the string level method described in this guide.

When is the best time to grade a yard in Southern Utah?

The ideal time for yard grading in St. George is fall (October-November) or early spring (February-March) when temperatures are moderate and you can seed or sod immediately after grading. Avoid grading during summer months when temperatures exceed 100 degrees --- the heat makes physical labor dangerous and dry soil resists compaction. Avoid monsoon season (July-September) as intense rains can wash away freshly graded soil before it is established.

Do I need a permit for yard grading in St. George?

Standard residential yard grading typically does not require a permit in St. George. However, if your grading project involves changing the drainage pattern that affects neighboring properties, significant fill or excavation (more than 2 feet of grade change), or work near a wash or flood zone, contact the City of St. George Building Department at (435) 627-4830 to confirm permit requirements.
