Common Questions About This Service

Grading decisions in the Lowcountry involve balancing slope requirements with soil conditions that affect how quickly water infiltrates or runs off, so here's what property owners ask before work begins.

  • What slope percentage is needed to prevent standing water?

    Most residential grading requires a minimum two-percent slope moving away from structures, though steeper slopes may be necessary on properties with heavy clay soils in Saint George that don't absorb water quickly.

  • How do you fix drainage without disrupting existing landscaping?

    Grading is planned to minimize disturbance to mature trees, gardens, and hardscaping, using swales and berms to redirect water around areas that need protection, though some rework is unavoidable in severely problematic zones.

  • When should grading be done relative to other site work?

    Rough grading happens after clearing and excavation but before utilities are installed, and finish grading occurs once all subsurface work is complete, just before landscaping or seeding begins.

  • What factors affect the cost of a grading project?

    Cost depends on the acreage being graded, the amount of cut-and-fill required, the distance dirt must be moved, and whether additional drainage features like culverts or French drains need to be installed.

  • Can you grade around septic systems without damaging them?

    Yes, operators mark septic tank lids, drain field boundaries, and distribution lines before grading begins, maintaining clearances that protect the system while improving surface drainage.
