Watersheds & Coastal Water Quality:
Impacts of Development - Impervious Cover
Watersheds & Coastal Water Quality:
Common Pollutants & Problems
• Bacteria: animal waste, septic systems, sediment runoff
• Chemicals: pesticides, chlorine, detergents
• Nutrients: fertilizers, sediment, under-vegetated lawns
• Litter: cigarette butts, trash
• Heavy Metals & Oil: breaks, engines, oil leaks, tire wear
• Natural Debris: yard debris, grass clippings, leaves
“Pollution reduces a community's ability to use waterways for
swimming, fishing, and drinking, and it adversely impacts wildlife
populations. These problems create negative impacts on a
community by reducing livability, suppressing the local economy,
and increasing the cost of using water as a natural resource”
(REALTOR® Magazine).

Questions & Answers
Components of a Stormwater System:
Neighborhood Drainage Features
Basic Definitions:
Swale: Rain falls on the impervious area of a residents property
and runs to the swale at the outer edges of the property.
Catch basins: A structure which captures surface water and acts
as a junction point where pipe segments connect.
Curb inlets: Basically do the same thing a catch basin, except it
captures water from the road rather than a back yard.
Pipes: Once the water falls into the catch basin or curb inlet, it
flows through a gravity fed pipes system falling out into the pond.
Weir: This slow draining is done using a weir structure.

HOAs are the “operators” of their residential stormwater system. An ongoing challenge is to balance
utility verses amenity.
