Rainwater runoff and low impact development
Rain either soaks into the ground or runs off of hard surfaces to be collected in a feature, such as a catch basin or stormwater drain. Collected runoff may evaporate back into the air, but most of it continues its journey to our local creeks, streams and rivers. As rainwater runs across surfaces, it can pick up dirt, oil, grease, trash and other contaminants that are harmful to aquatic life and water quality.
Clark County has regulations in place that help collect rainwater and treat it to remove contaminants and allow the water to soak back into the ground. Some of these features are called Low Impact Development (LID), while others are referred to as stormwater facilities. LID features include rain gardens, bioretention, green roofs, pervious pavement and design layouts that protect natural areas and vegetation. Stormwater facilities include detention ponds, infiltration basins, vaults and drywells.
You may have LID or stormwater facilities in your neighborhood. In some cases, homeowners are responsible for maintaining their neighborhood stomrwater facilities and LID.
