Nutrient Processing. Surface water runoff in urban areas can include
significant quantities of chemical nutrients, particularly nitrogen and phosphorous.
When these nutrients reach local water bodies, they can contribute to eutrophication.
(Eutrophication is a naturally occurring process in which nutrients accumulate in a body
of water over time; the term is often used to signify acceleration of this process by
human activity.) Several of the LID components described in this UFC (see Chapter 8)
filter out these nutrients to various degrees of effectiveness, depending on the design.
LID approaches that utilize vegetation not only filter nitrogen and phosphorous out of
