What's so special about trees and LID?


Use of trees to manage stormwater runoff includes several practices. Tree trenches and tree boxes (collectively called tree BMPs), the most commonly implemented tree BMPs, can be incorporated anywhere in the stormwater treatment train but are most often located in upland of the treatment area, typically in places that have enough room for the tree's roots.

Urban Forests


Urban forms of nature - including trees, parks, gardens, and natural areas - enhance quality of life in cities and towns. The experience of nature improves human health and well-being in many ways. Nearly 40 years of scientific studies tell us how.

As part of a recent revision, a wealth of information about trees as stormwater management techniques has been added to Minnesota's Stormwater Manual. Most of this material can be found as a single collection. This combines several documents related to tree trenches and tree boxes. Individual documents can be viewed by clicking on the appropriate link.
