Design Principles and Regulatory Requirements for Earthen Dams Presented by Donald W. Lake, Jr., PE The Dam Safety Section of the New York State Department of Environmental Conservation issued new rules and regulations for dams on July 29, 2009. Whether a dam is designed for recreation, fish & wildlife, stormwater management, irrigation or flood protection, the new regulations need to be understood by dam owners, operators, and designers to be in compliance. The presenter will review the new dam regulations in detail discussing the evaluation of hazard class, creation and implementation of emergency action plans, preparation of inspection and maintenance plans and the thresholds and process for applying for an NYSDEC Article 15 Permit. Technical elements presented will include dam site hydrology for structure proportioning, geotechnical design of embankments for stability including site foundation geologic investigations, compaction and drainage, and hydraulic structures for outflow control including gates and valves. Construction specifications will also be reviewed. By the end of the session attendees will be able to establish the Hazard Class of a dam; understand the requirements, regulations, and procedures for the state permitting process in New York; and understand the hydrologic and hydraulic criteria and procedures to establish geometry for earthen dams. Participants will learn key field operations required for sound construction of an earthen dam and learn critical components of the design process in meeting project objectives.
Donald W. Lake, Jr., P.E. graduated from the State University of New York at Buffalo in 1970 with a B.S. degree in Civil Engineering. He is a licensed professional engineer in New York, a Certified Professional in Erosion and Sediment Control (CPESC), and a Certified Professional in Stormwater Quality (CPSWQ). Don “retired” from the USDA-Natural Resources Conservation Service (NRCS) in 1995 after 27 years of service. He served as Engineering Specialist to the NYS Soil & Water Committee from 1996 to 2006 assisting NYS-DEC with the implementation of their stormwater program. During his tenure with the NRCS, he served as a design engineer and as a field Project Engineer in charge of construction of floodwater retarding dams Don has also served as the State Design Engineer overseeing the agency design section, and as the State Conservation Engineer in charge of all engineering operations for NRCS in the state. Don has personally designed and/or constructed over 65 earthen dams throughout his career and authored the NRCS Laboratory Testing Manual for dam construction materials for agency use in the design of dams and inspection control. He received an Outstanding Achievement from USDA-NRCS for his development of an innovative design process to repair damaged embankment spillway conduits. He is an Adjunct Professor at Syracuse University and at The State University of New York. This program qualifies for 7 CE hours for: Programs are 8:30am to 4:00pm and include lunch. NOTE: Ensuring Compliance with the 2010 ADA Standards for Accessible Design and Applicable Building Codes will run until 5:00pm. Registration Fees:
