Five Steps to Building Soil
Best management practices (BMPs) during construction
1. Retain and protect native topsoil and vegetation where practical.
2. Restore distrubed soils to restore healthy functions by
a. Stockpiling and reusing good quality site soil, or
b. Tilling 2 to 3 inches of compost into poor site soils, or
c. Bringing in 8 inches of compost amended topsoil
3. Loosen compacted subsoil, if needed, by ripping to 12-inch depth.
4. Mulch landscape beds after planting.
5. Protect restored soils from erosion or recompation by heavy equipment.
