The City of Grand Island follows a Stormwater Management Program (SWMP) that has been designed to reduce the impact of our activities to the maximum extent practicable. The City also abides by an NPDES permit which prohibits non-stormwater discharges into our local waterways. Our SWMP includes pollution reduction practices for active construction sites, completed construction sites, illegal discharges, illicit connections, new developments, and daily municipal operations. The program also includes education initiatives for the public, businesses, industries, and municipal workers.
