Training & Workshops

One and Two Day Workshops
Offering a New Comprehensive Planning and Technological Solution to Urban Stormwater Management, Combined Sewer Overflows, and Sanitary Sewer Overflows


The Low Impact Development Center, Inc., a non-profit 501 (c) (3) organization, offers one- and two-day courses on Low Impact Development Technology. The one-day course offers an overview and introduction to the Low Impact Development (LID) technology. This course gives the participant insight into the philosophy, design and administrative approach, and implications of the technology. Demonstration of the application of the technology is used to allow the participant to gain an understanding of the process.
The two-day seminar expands on the foundation of the one-day seminar by allowing the participant to work through examples and have greater exposure to the technological tools and research that is the basis for LID design.


This workshop will provide a thorough overview of the new Low Impact Development (LID) objectives, economic/ environmental benefits, design principles and management practices. The course will introduce the innovative LID paradigms for protection and restoration of watershed hydrology, stormwater management, protection of receiving waters, Combined Sewer Overflows, and nonpoint pollution control. Attendees will be introduced to a new perspective in urban stormwater management and will gain a practical understanding of how to apply this powerful new technological solution for watershed and water resources protection.

Who Should Attend?

This new technology involves multiple disciplines and has far reaching impacts in urban stormwater management, land use p?lanning, water resources protection, site planning/design, best management practices, building requirements and construction and maintenance of stormwater infrastructure. LID will be of interest to local, state and federal government administrators and regulators; developers, builders, contractors; land use/development planners, civil/environmental engineers, landscape architects; environmental professionals/consultants; environmentalists and interested citizens.

Learning Objectives

Course participants can expect to achieve the following: 1) Understand the economic, environmental and watershed protection limitations of conventional stormwater management and environmental mitigation technology; 2) Understand the new paradigms, principles and practices of LID watershed management technology and public participation in pollution prevention; 3) Understand the application of this new technology to meet the requirements and objectives of federal and state stormwater regulations and for the retrofitting existing urban areas to address CSO’s and protection of receiving waters; and 4) Know where to get more specific information about LID planning and design criteria.


The course will demonstrate how to develop land and maintain the predevelopment hydrologic regime by using new stormwater management principles and practices to create a hydrologically functional landscape. Urban applications will demonstrate and review the principles and practices for retrofit of existing infrastructure to address CSO, SSO, and water quality problems. The Two day session includes working examples and more detailed information on current research findings and applications. During the two-day session participants will receive hands on training through worked examples and calculations.
Attendees will receive copies of the "Low Impact Design Manual" and handouts on public education, bioretention, and presentation materials.


The one-day lecture/participation course presented primarily with instructional and diagrammatic slides, and handouts. Handouts will include outlines of slides and overheads and papers on various aspects of LID technology. Open discussion and questions will be encouraged throughout the session. Participants will work through critical portions of the design approach and application.
The two-day course will expand on the principles and technological base of the first day. Included will be a thorough discussion of the state-of-the art research, training on the use of LID BMPs, and a design charette.
