Controlling surface erosion

During the course of your project, you need to manage your site with soil protection in mind. For many reasons, you want to expose the least amount of soil possible. Naked soil can easily wash away, blow away, or become a slippery, muddy mess. When major grading is inevitable, here are some strategies you can use (see Figure 14-1 for an overview):

  • Make sure that all grading, whether temporary or permanent, directs water where it can be controlled.
  • Maintain natural landforms where possible.
  • Avoid concentrating water in one big stream. Spread water out, and look downstream to pinpoint where your water is going.
  • Filter runoff with erosion control fabric, straw wattles, silt fencing, and other strategies so that only clear, clean water leaves the site. (I explain these strategies in the following sections.)
  • If you expect slopes to go through a rainy season before permanent landscaping is established, seed or hydroseed them with suitable temporary plantings, or mulch them with straw or hay. (For more information, see the section on hydroseeding later in this chapter.)
  • Where the risk of runoff problems is low (stable soil and gentle slopes, for y^JV example), a 3- to 4-inch layer of ordinary recycled organic mulch, available 1^11 from local recyclers or municipalities, can be spread on the area and simply left in place after planting is done.
