Stormwater Best Management Practice Design: Vegetative Biofilters

COURSE NO: C10-003
COURSE PROVIDER: Michael Nilsson, P.E.
Stormwater Best Management Practice Design: Vegetative Biofilters
Course Highlights

This online engineering PDH course provides design guidance for BMPs referred to as vegetative biofilters.  Three different types of these on-site BMPs are described in this course and include grass swales, vegetated filter strips and bioretention cells.


The goals and objectives of best management practice (BMP) for stormwater management are as diverse as the situations to which they are applied.


This 10 PDH online course is applicable to civil and geotechnical engineers, site developers, and contractors as well as design and construction personnel involved with the planning and design of stormwater systems.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Overview of grass swales, vegetated filter strips and bioretention cells
  • Review general design considerations associated with vegetative biofilters
  • Analytical procedures for runoff volumes and rates, and sediment and nutrient loading (runoff and loading calculation examples included)
  • Factors affecting vegetative filter strips
  • Design guidance and procedures for vegetative filter strips
  • Grass swale design guidance and considerations
  • Guidance on bioretention cells
Course Document

In this professional engineering CEU course, you need to review Sections 1 through 7 of the US Environmental Protection Agency (EPA) Publication EPA/600/R-04/121A, "Stormwater Best Management Practice Design Guide: Volume 2 Vegetative Biofilters".
