Erosion Control
EROSION & SEDIMENT CONTROL
- A single entry or exit to the site reduces the sediment that is tracked off site to surrounding roadways.Stormwater runoff can be controlled and directed to a sediment control area by constructing a raised barrier at the entrance as well.
- Locate materials and soil stockpiles away from runoff or drainage paths and use tarps to cover and protect them. Divert runoff around stockpiles unavoidably located in drainage paths using a perimeter bank uphill.
- Use biodegradable erosion control mats to protect exposed earth. These are particularly useful on high risk soils and steep sites where there is a delay in building or site rehabilitation.
- Use barriers to trap coarse sediment at all points where stormwater leaves the site, before it can wash into gutters, drains and waterways. Install sediment fences down slope of the disturbed area, usually along the lowest site boundary with the ends returning uphill. Inspect barriers after storms and remove sediment.
- Regularly sweep adjacent streets and gutters clean - do not hose them. Relocate sediment on site or dispose of it suitably. Remove accidental spills of soil or other material immediately.
- Maintain curbside vegetation in a healthy state as it can function as an additional filter for sediment.
- Cut brick, tile or masonry on a pervious surface such as grass or loosened soil within the property boundary. The same applies when cleaning equipment. Waste concrete, paint and other solutions used on site should be properly disposed of so they do not contaminate stormwater.
- Reduce the water you use inside and outside your home through improved water use efficiency, by using rainwater and designing your garden to need less water.
Indoor plants can be used to filter and improve indoor air quality
- - Vegetation can be used for screening, as a windbreak and to frame select views.
- - The topography of a garden should ideally reflect the original relief to minimise the impact on drainage patterns but bunds can sometimes be created to enhance visual and/or acoustic privacy.
