Integration of Sustainable Infrastructure Into Existing Stormwater Management Practices On Military Lands.

Abstract Executive Order 13514 and the Energy Independence and Security Act (2007) stipulate that all Federal land holding agencies are to immediately implement Sustainable Infrastructure into stormwater systems. The DoD is operating to meet that mandate, even as that mandate presents some unique challenges due to the nature of the military’s scope of activities, scale of operations, and distribution of lands. Currently, there is a need to investigate and develop a methodology for site selection of Low Impact Development (LID) designs and technologies for storm water management particularly in areas where an existing stormwater infrastructure may already exist. The techniques of LID are innovative, site design strategies and practices that work with the biological and physical systems of a site to achieve water management and conservation goals. Small scale, decentralized, close-to-the-source controls provide the means to meet the environmental standards for storm water management under the auspices of National Pollution Discharge Elimination System (NPDES), and Phase II of the Clean Water Act (CWA). As part of the proposed work, the authors conducted GIS analysis, investigations of LID technologies and series of sampling and analysis events of existing soil, water quality and hydrology at military installations to develop a methodology for installations to use for selection of LID technologies and adjustments for optimization of time and cost; and speedier integration into the existing stormwater network. Investigations looked at implementation, costs, environmental and societal benefits. The intent of this project is to provide a methodology for the selection and siting of LID technologies.
