A perc test takes an average of around two hours, but it can range from one hour up to around six hours. Perc tests that require wider or deeper holes and those that require multiple holes dug throughout your property will take longer because there’s more excavation involved. The actual filling of the hole and monitoring to gauge the rate of percolation should take under an hour per hole.

If you notice small bumps on your lawn, you can flatten them by gently treading them down when the ground is wet. A lawn with larger lumps may need to be regraded by a professional to flatten it out and improve the overall drainage of the yard to prevent future lumps from forming.

Pea gravel is hands down a top pick for managing landscape drainage.  These small stones allow water to flow through easily by creating natural gaps that promote runoff. Beyond functionality, pea gravel also offers visual versatility. Homeowners will find a range of earthy tones like gray, brown, blue, and even red, making it easy to match with different outdoor styles and plantings.

For minor unevenness, you don't necessarily need to remove grass before leveling. You can apply a topdressing mixture to fill in low areas and even out the surface. However, for more significant unevenness or deep depressions, it might be necessary to temporarily remove the grass to ensure proper leveling and soil compaction. After filling and leveling, you can replace the grass or consider reseeding the area.
