Land development projects
typically replace existing natural ground features with new impervious
surfaces such as driveways, rooftops, sidewalks and streets. Stormwater
runoff occurs when water from snow melt and rain can no longer
infiltrate into the ground. The runoff can carry toxic materials into
our stormwater drainage systems including:
Nutrients (such as phosphorous and nitrogen)
Wetlands, streams, lakes and rivers ultimately receive the discharging waters from all City stormwater systems.
