Landscape architects are often responsible for the design of stormwater systems. The US EPA National Stormwater Calculator is a new planning and design tool to document estimated performance (stormwater runoff reductions) of green infrastructure stormwater best management practices (BMPs). The National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). Estimates are based on local soil conditions, land cover, historic rainfall records, future climate change scenarios, and BMP designs. It is designed to be used by anyone interested in reducing runoff from a property, including: site developers, landscape architects, urban planners, and homeowners. Landscape architects will learn how to use the National Stormwater Calculator for potential projects. Attendees will also learn about future updates to the calculator.

Learning Objectives:

  • Learn about urban stormwater management planning and design tools & models.
  • Learn how to use US EPA’s National Stormwater Calculator, including potential applications for regulatory and voluntary projects.
  • Learn about green infrastructure (stormwater BMPs) climate resiliency planning and future updates to the National Stormwater Calculator.

The EPA Stormwater Calculator Tool will be very useful. The Tool was well presented by Jason Berner. A general comment for all topic exams is that it would be helpful to know which exam questions were not answered correctly to facilitate learning from mistakes.
