Use of trees to manage stormwater runoff encompasses 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 areas of the treatment train.
Tree BMPs are one component of urban forestry. Urban forestry is a broad term that applies to all publicly and privately owned trees within an urban area, including individual trees along streets and in backyards, as well as stands of remnant forest (Nowak et al. 2001). This page includes three sections covering general information about trees, tree trenches and tree boxes as BMPs, and urban forestry.
The following pages address incorporation of trees into stormwater management under paved surfaces. These pages may be viewed as a single article
