What Is Stormwater?Stormwater is rainwater that runs off surfaces such as rooftops, lawns, driveways, paved streets, and parking lots. Urbanization has two major impacts on stormwater runoff. First, it increases the rate and volume of runoff relative to a predeveloped condition. The increased runoff rate increases the flow rate in rivers and streams causing streambed scouring, streambank erosion and increased turbidity. Second, when runoff flows over roads, parking lots, driveways and lawns it picks up harmful pollutants such as oils, greases, pesticides, fertilizers, pet waste, toxic metals, and other chemicals. This polluted runoff enters the stormwater conveyance system. Much of downtown Granite Falls discharges to Lake Gardner, prior to draining to the Pilchuck River.

- The Washington Department of Ecology, developed a new Stormwater Management Manual in 2019. This manual, which has been adopted by Granite Falls, provides significant information, and sets minimum standards regarding Stormwater treatment and detention as well as issues related to erosion control during construction.
- The Washington Department of Ecology adopted the NPDES Western Washington Phase II Stormwater Permit on January 17, 2007 . This permit was issued to 80 Cities and 5 Counties in Western Washington . The Phase I permit is for larger Cities and Counties and a Phase II Permit for small jurisdictions like Granite Falls . The main goal of the NPDES program is to effectively prohibit non-stormwater discharges into “waters of the state” and to reduce the discharge of pollutants into the stormwater conveyance system.
- Public education and outreach
- Public involvement and participation
