About the workshop:

The Storm-EZ Permitting Tool has been developed by Withers & Ravenel in partnership with NCDENR, NCSU-BAE, the NC Coastal Federation, and the NC LID State Technical Review Team. Storm-EZ is an Excel spreadsheet-based stormwater permitting tool with computations based on the SCS Discrete Curve Number Method and current research findings on hydraulic and hydrologic performance of BMPs. Designers enter pre-development and post-development land use data and design data for stormwater practices. Then, Storm-EZ reports whether the project meets stormwater regulations and also quantifies where the project falls in the conventional-to-low impact spectrum.

When Storm-EZ is finalized, it will replace the general state stormwater permit application form, the separate BMP Supplement Forms (currently one per device is required), and the Operation and Maintenance agreements.

The new Storm-EZ tool will be debuted and participants will learn how to use Storm-EZ to analyze site plans and estimate the conventional versus low impact fates of runoff to determine if a site meets the state's new LID defnition. Workshop participants are encouraged to bring a laptop with Excel to class.

The training will be from 9:00am to 4:30pm on day 1 with an optional practice session on day 2 from 2:00-4:00pm. Detailed agenda will be posted shortly.
