  • Municipalities 
  • Engineers 
  • Contractors 
  • Consultants 
  • Non-regulatory 3rd Party Inspectors 
  • Civil Consultants/Students 
  • Environmental Consultants/Students 
  • Landowners, Permittees, and Construction Site Operators 

Curriculum: Intro to Basic Stormwater Calculations

This course consists of stormwater calculations associated with designing a bioretention basin for a suburban site. 

Topics include the following: 

  • Conceptual design using a bioretention case study 
  • Calculating total storm volume,  
  • Calculating basin storage,  
  • Determining peak flow rates,  
  • Pipe sizing, and  
  • Basic bioretention design. 

Learning Objectives

The main objective of this course is to provide you with an introduction to basic stormwater calculations associated with designing a bioretention basin for a suburban site. 

  • Demonstrate how to calculate total stormwater volume from a design storm (using the Simple Approach and the Curve Number Method). 
  • Describe peak flow rates and how to size for them (using the Rational Method and Manning’s Equation).
  • List the basic considerations of bioretention sizing and design.
