Site Prep First

Court Design & Site Preparation in San Diego County

A court that drains, plays flat, and holds its base for years starts with the ground work done right.

What Goes Wrong

Why courts settle, crack, and pool water within a few years

Each failure traces back to a specific step that was skipped or rushed during ground preparation.

Inadequate Compaction

A subgrade compacted below 95 percent relative density shifts under load, pushing cracks through the base and any surface above it.

Verified Compaction Standard

The builder compacts the subgrade to the required standard before any base material is placed, not after.

No Drainage Slope

A flat or reverse-graded court traps rainwater in low spots, softening the base and accelerating surface wear.

1% Surface Slope

The builder establishes a consistent 1 percent slope in one direction so water clears the court after every rain event.

Unstable Subgrade Soil

Clay-heavy or sandy soil left in place beneath the base moves seasonally, causing the court to heave and settle unevenly.

Excavation to Stable Depth

Organic material and unstable soil are removed down to a stable subgrade before compaction work begins.

Obstacles Left in Place

Buried roots, rocks, or old concrete fragments create pressure points that crack the base from below over time.

Full Site Clearance

Roots, debris, and old slabs are identified in the site plan and removed before excavation reaches final depth.

Ground-Up Preparation

What happens below the surface determines how long the court lasts

Measurement, grading, drainage planning, and compaction all happen before a base material is ever placed.

San Diego County lots often combine sloped terrain, clay-heavy or sandy soil, and limited backyard depth, conditions that require careful assessment before a court footprint is laid out. The builder measures the available space, checks existing grade, and identifies drainage paths. That information shapes the layout and determines how much excavation and slope correction the site actually needs.

Excavation removes organic material and unstable soil down to a stable subgrade. The subgrade is then compacted to a standard that prevents settling, typically 95 percent relative compaction for a concrete base. Skipping or under-compacting this step allows the base to shift over time, which causes surface cracking that no patch repair can permanently resolve.

Drainage planning runs alongside compaction work. The builder establishes a surface slope, usually 1 percent in one direction, so water clears the court after rain rather than collecting in low spots. On coastal and canyon lots, where soil drainage behavior varies, this step is checked twice: once during the evaluation and again after grading is complete.

Why Choose Us

Why San Diego County Sports Courts for design & site preparation?

Ground preparation is where courts are won or lost, here is what makes the difference at this stage.

Evaluation Before Any Estimate

No scope is written until a builder has looked at the ground, the grade, and the drainage in person.

Itemised Written Scope

Base prep, surfacing, and line marking appear as separate line items so nothing is bundled or hidden.

Backyard to Commercial Scale

Site prep is handled the same way whether the court is a backyard half court or an HOA multi-sport facility.

Local Soil & Drainage Knowledge

Builders familiar with San Diego County’s coastal and inland soil conditions assess drainage behavior on site.

Final Walkthrough Included

A sign-off check happens before the job closes, so base readiness is confirmed, not assumed.

Common Questions

Questions about court design & site preparation

Why does my yard need site prep before a sports court is built?

Without proper site prep, the court base will shift, crack, or drain poorly within a few seasons. A stable, level sub-base is what keeps the surface flat and the lines true over time. Skipping it trades short-term savings for expensive repairs later.

Can a court be built if my yard has a slope or low spots?

Yes, most sloped or uneven yards can be graded to a usable level. The amount of cut-and-fill work depends on how steep the grade is and how large the court footprint needs to be. An on-site evaluation confirms what grading is required before any estimate is written.

Do you need to fix drainage before the court goes in?

Yes, drainage is addressed during site prep, not after. Water pooling under a court base causes heaving and surface cracking. The on-site evaluation checks existing drainage patterns, and any corrections are itemised in the written estimate before work begins.

What happens during court site preparation?

Site prep covers clearing the area, grading the ground to the correct slope, compacting the sub-base, and resolving any drainage issues. Each of those steps is scoped during the on-site evaluation and listed in the itemised written estimate so you know exactly what is planned.

Can you build a court if there are trees, roots, or old concrete in the way?

Yes, tree removal, root grinding, and old concrete demolition are all part of site prep. The on-site evaluation identifies what needs to come out, and that work is included in the itemised estimate. Leaving roots or old slabs in place would undermine the base over time.

How much clearing, digging, or demolition is included in site prep?

The scope varies by yard condition and is defined during the on-site evaluation. The written estimate itemises clearing, excavation depth, and any demolition separately so you can see exactly what each phase covers before approving the work.

Will hidden soil or drainage problems change the site work once you start?

They can. If excavation uncovers unexpected soft soil, buried debris, or a drainage issue not visible at the surface, the scope may need to expand. When that happens, the change is documented and reviewed with you before any additional work proceeds.

How do you know if my yard is big enough for the court I want?

The on-site evaluation measures the available space and checks setbacks, slopes, and obstructions against the court dimensions you want. If the full size does not fit, a scaled-down or multi-sport layout is mapped out so you can compare options before committing.
