Addressing New Stormwater Policies in the Redesign of the National Grove of State Trees at the United States National Arboretum

Title of Document: ADDRESSING NEW STORMWATER POLICIES IN THE REDESIGN OF THE NATIONAL GROVE OF STATE TREES AT THE UNITED STATES NATIONAL ARBORETUM Kory A. Kreiseder, MLA 2012 Directed By: David N. Myers, PhD. PLA, ASLA, Department of Plant Sciences and Landscape Architecture The National Grove of State Trees at the United States National Arboretum is in need of redesign to meet ecological and social needs. The Grove serves as a scientific and cultural landscape and can be repurposed to serve the public as an ecological demonstration for contemporary environmental issues. In an intensive effort to clean up the local rivers of the District of Columbia and the Chesapeake Bay, the two agencies of the District Department of the Environment and DC Water have enacted stormwater runoff fees, based on impervious surface fees, on all property owners located in the District of Columbia. The redesign of the Grove is compounded by the Arboretum’s need to add more parking to the area where the Grove is currently located. The objective of this thesis is to reimagine the design and interpretation of the Grove as well as address the impervious area charge assessments.
