Course Description

This course addresses the concept of unit processes and operations as applied to stormwater management. Students will learn a simplified framework for facilitating communication between stormwater management professionals and how to promote the development of a site-level stormwater management strategy that serves as a blueprint for the design process. The importance of basin volume and the five categories of stormwater controls will also be covered.

Learner Outcomes

Upon completion of Stormwater I and II and Stormwater Management Hydraulics and Hydrology I and II, students are prepared to take the American Public Works Association (APWA) Certified Stormwater Manager (CSM) certification exam.

To demonstrate eligibility, candidates must submit an application documenting the completion of one of the following pathways:

  • High school graduation or equivalent and seven years of relevant work experience
  • Associate degree or equivalent trade school certificate and five years of relevant work experience
  • Bachelor’s degree and three years of relevant work experience
  • Master’s degree and two years of relevant work experience
  • Doctoral degree and one year of relevant work experience

Relevant work experience is that performed within or for a public entity in one or more aspects of stormwater management as defined in the CSM target audience description and illustrated in the CSM Content Outline.

Please note that individual state requirements may vary. Students are responsible for checking with their state’s governing body for state-specific requirements.
