Low Impact Development (LID) Applications for Water Resource Management (PDF)

Purpose and Background

Low Impact Development (LID) is an innovative approach to storm water management that is being implemented by federal agencies, as well as state, and local governments for aquatic resource protection and regulatory compliance. LID is a site-level storm water management approach with an objective of maintaining the hydrologic cycle or meeting targeted watershed objectives. This is accomplished by combining planning and design strategies, which use conservation approaches and techniques to reduce site development impacts, with Integrated Management Practices (IMPs).

LID is implemented and used because of the potential life cycle cost savings, superior environmental protection, and ability to leverage funds from other programs, such as maintenance budgets, to construct IMPs. This approach is useful for urban redevelopment, and is being used in Combined Sewer Overflow (CSO) control programs in large cities. LID is also being used in rural and smaller communities for Phase II NPDES permits because of the flexibility in construction and the ability to phase the implementation of the program. ASCE’s LID seminar focuses on the engineering and technical issues associated with the planning, engineering, construction, and determining the effectiveness of LID. It will give the practicing engineer a foundation to begin to design and incorporate LID.
