This continuing education online PDH course is NY approved. This course is also accepted in the States of AK, AL, AR, DE, FL, GA, IA, ID, IL, IN, KS, KY, LA, MD, ME, MI, MN, MO, MS, MT, NC, ND, NE, NH, NJ, NM, NV, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WI, WV and WY.

This course provides guidelines to assure that landscape planting and vegetation management provide aesthetic and environmental benefits without compromising the reliability of levees, floodwalls, embankment dams, and appurtenant structures.  The dimensions of the vegetation-free and root-free zones defined in this document provide the minimum acceptable buffer between vegetation and flood damage reduction structures.


This online PDH course is intended for civil and hydraulic engineers involved with the design and maintenance of levees, floodwalls, embankment dams, and appurtenant structures.


In this course, you need to review the U.S. Army Corps of Engineers Technical (USACE) Letter No. 1110-2-571, “Guidelines for landscape planting and vegetation management at levees, floodwalls, embankment dams, and appurtenant structures”, dated April 10, 2009, and provided below. Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 3 PDH credits. The quiz will be based on this USACE publication.
