The two most common ways to cover bare ground and stabilize erodible slopes are hydro-seeding and blanket. Hydro-seeding is often used on larger areas, by applying a slurry of seed and mulch that is sprayed in a uniform layer on a slope. Erosion blanket, available in many forms and made of different biodegradable material, provide instant protection, anchored with staples, particularly the edges and the up-slope side, overlap joining sections to ensure site protection.
Straw wattles installed, help to stabilize slopes by shortening the slope length and by slowing, spreading and filtering overland water flow. This helps to prevent sheet erosion as well as rill and gully development, both of which occur when runoff flows uninterrupted down a slope. Storm water runoff carries sediment and seeds off slopes as it gathers velocity, but straw wattles capture that sediment and hold it on site, enabling seeds to settle and germinate, aiding the re-vegetation process..
Whenever possible, slope should be planted with plants native to the area; plants will already be adapted to the soil conditions and will need the least amount of maintenance. Native grasses often installed using plugs are our most common choice for long-term stability.
Slope Irrigation: plants need water initially. To insure the irrigation system, a master value is installed ahead of main control to assure proper valve function. A flow controller can be installed to monitor the amount of water flowing thru the system. 1 GPH emitters are used for deep watering.
