The mission of the Hydrology and Low Impact Development (LID) Center of Expertise in Sustainability (CXS) is to provide guidance and technical support for the design and construction of LID features to manage stormwater and reduce the impact of the constructed environment on the surrounding natural resources. The Energy Independence and Security Act (EISA) of 2007, Section 438 requires that any development or redevelopment project involving a Federal facility with a footprint that exceeds 5,000 square feet shall use site planning, design, construction, and maintenance strategies for the property to maintain or restore, to the maximum extent technically feasible, the predevelopment hydrology of the property with regard to the temperature, rate, volume, and duration of flow. LID features can be implemented on projects to meet the requirements of EISA Section 438. Careful planning and development can strategically create areas that reduce quantity of runoff from a site.

The Army Low Impact Development Technical User Guide is provided to assist DoD planners, engineers, and stormwater managers in meeting the requirements of the Energy Independence and Security Act (EISA) of 2007, Section 438, for their facility.
