Stormwater Management Plan: Phase I & II

Stormwater is water from rain or melting snow that does not immediately soak into the ground. Instead, stormwater flows across hard surfaces such as concrete, asphalt pavement, or roofs and can pick up pollutants like lawn chemicals, automobile oil and grease, airborne dust and sediment, and pet waste.

Unlike the water we use in our homes, stormwater does not go to a wastewater treatment plant. Instead, stormwater flows directly to the Boise River or seeps into the groundwater.
