Low-impact development for impervious surface connectivity mitigation: assessment of directly connected impervious areas (DCIAs)

W Sohn, JH Kim, MH Li - Journal of Environmental Planning and …, 2017 - Taylor & Francis
Urbanization increases directly connected impervious area (DCIA), the impervious area that
is hydraulically connected to downstream drainage by closed pipelines. Although the
benefits of low-impact development (LID) have been examined in other studies, its effect on
alleviating DCIA levels has seldom been assessed. This study measured the DCIA of urban
watersheds in Houston, TX, USA. Five land-use types were categorized and the contribution
of LID facilities to reducing DCIA in each type was estimated by using Sutherland's …
