Typical Practices and Controls
Planning practices include several related approaches that were developed independently by various practitioners. These differently named approaches include similar concepts and share similar goals in protecting water quality.
- Conservation design, also called Conservation Development
- Better Site Design
- Green Infrastructure.
Planners select structural LID practices for an individual site in consideration of the site's land use, hydrology, soil type, climate and rainfall patterns. There are many variations on these LID practices, and some practices may not be suitable for a given site. Many are practical for retrofit or site renovation projects, as well as for new construction. Frequently used practices include:
- Bioretention cells, also known as rain gardens
- Cisterns and rain barrels
- Green roofs
- Pervious concrete, also called "porous pavement", similar to Permeable paving
- Grassed swales, also known as bioswales.
- Commercially manufactured stormwater management devices that capture pollutants (e.g., media filters) and/or aid in on-site infiltration

Famous quotes containing the words typical, practices and/or controls:
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
“To learn a vocation, you also have to learn the frauds it practices and the promises it breaks.”
—Mason Cooley (b. 1927)
“Comparatively, we can excuse any offense against the heart, but not against the imagination. The imagination knows—nothing escapes its glance from out its eyry—and it controls the breast.”
—Henry David Thoreau (1817–1862)
