Basic Wetland Delineation is a 40-hour training course that focuses on procedures used to delineate wetland boundaries using the 1987 Corps Wetland Delineation Manual (Technical Report Y-87-1) and the Regional Supplement: Arid West Region (2008). The course will also discuss the Regional Supplement: Western Mountains, Valleys, and Coast Region (2010). The main objective of this training is to provide participants with a comprehensive and hands-on introduction to delineation of jurisdictional wetlands in California. Field demonstrations of proper procedures to identify wetland vegetation, hydric soils, and wetland hydrology indicators will be covered. Examples of challenging delineations will be discussed – atypical situations, problem areas, difficult wetland situations in the Arid West, and delineations for restoration projects. This course will consist of 50% lecture and 50% field excursions and laboratory exercises, emphasizing a hands-on approach. Participants will work closely with instructors in small groups to learn how to delineate extent of jurisdictional wetlands in the field. Various approaches to delineation of different wetland types and sizes will be discussed and demonstrated. After successful completion of this course, participants will receive certification that documents 40-hours of training in the use of the 1987 Corps of Engineers Wetlands Delineation Manual and two Regional Supplements: Arid West Region/Western Mountains, Valleys, and Coast Region.

To be able to complete a wetland delineation using the guidelines and methods used by the Corps of Engineers according to Section 404 of the Clean Water Act.
1. Understand and apply the delineation methods provided by the Corps
2. Understand the field observations necessary to recognize the three wetland indicators and complete a delineation
3. Develop an awareness of the issues that affect jurisdictional determinations and identify how these issues may affect the outcome of a delineation

Lastly, we will present examples from actual delineations and permitting scenarios to demonstrate successful techniques to get a verified delineation and discuss the “grey areas” of regulatory permitting.

—please bring questions-


Training will be led by bay area delineation experts Aaron Arthur, MS, Tanner Harris, MS/PWS

1st three days will be primarily classroom and lab based in Tiburon.

4th and 5th days we will visit sites in Marin County to apply discussion topics to real situations as well as perform a delineation in teams.
