The Water Quality category encompasses actions that a shoreline landowner can take to reduce or eliminate the amount of sediment, chemical and organic pollutants that are discharged to lakes and marine waters directly or in surface runoff.
The runoff associated with rain events is typically referred to as “stormwater,” but it is important to recognize that the majority of surface runoff is from light, steady rainfall and not just occasional storms. Therefore, in this credit, we use the term “rainwater management” in addition to stormwater to refer to the runoff from regular rainfalls as well as bigger storms.
In this section:
This credit applies to actions that minimize the amount of impervious surface area and encourages the use of low impact development measures where feasible to further reduce the quantity and improve the quality of surface runoff.
This credit awards points to discourage using toxic chemicals or chemically treated wood in the construction and maintenance of overwater structures, or landscaping structures in riparian areas.
This credit encourages removal of creosote-treated pilings and creosoted beach debris.
This credit discourages use of synthetic or inorganic herbicides, pesticides, or fertilizers in routine landscape maintenance.
This credit applies to design of onsite sewage treatment systems in order to minimize the release of pollutants to downstream receiving waters.
