If you run a contracting or home building company that offers complete packages including everything from site preparation to the finishing details on the house, you need to make a plan for controlling erosion on each building site you agree to handle. Even when you partner with a grading company instead of doing the bulldozer work yourself, you're likely left with the responsibly of either hiring a landscaping crew or tackling erosion yourself. Use these four tips whether you do it or hire a team for help.
Reserve the Topsoil
While it's always necessary to scrape away the loose topsoil where the foundation is being built or poured, some grading companies choose to clear the entire property of topsoil to sell it. Ask your team mates to leave behind as much topsoil as possible after cutting down and uprooting the trees. This decomposing mix of leaf litter, bark, and other organic matter helps new grass and landscaping plants get established faster and grow stronger for years to come.
Minimize Grade Levels
Most sites need at least a little leveling of the dirt that will support the house you plan to build. Whether you are working in a hilly area or a flat one, try to plan the site around minimal grade changes to cut down on the number of raw dirt slopes. Explain to your customers why a specific spot works best for their house to cut down on the risks of erosion that kills your landscaping plants, mudslides, and foundation damage too.
Plant Temporary and Permanent Grasses
No amount of plastic webbing or rope nets work quite as well as the natural root mats of grasses. Try seeding a layer of ryegrass, barley, or tall fescue the day after grading is complete to get an immediate layer of vegetation to keep rain drops from throwing loose soil into the air. These temporary crops can be cut down to die after a few months, allowing the landscaping crew to start a lush turf lawn right away by planting into the residue of the first grasses.
Are there areas with loose dirt that still feature quite a few trees left for shading the new house? Mulching can work better around wooded areas and edges than grass, and it also offers great erosion control right around the foundation without the long wait for establishing plants. Stick with organic materials like wood chips and pine straw so the mulch breaks down eventually and keeps enriching the soil after the homeowners move in and take over the yard maintenance.
