PR: Stormwater Management Training Series

Cornell Cooperative Extension of Orange County

Announces Stormwater Management Training Series

Cornell Cooperative Extension of Orange County is hosting a Stormwater Management Training series. The first class was held on January 24, and the second class of the series will be held on February 21. The program offers a four-part series of workshops for professionals involved in stormwater management. Professionals will be able to learn about the latest trends and standards along with new techniques and evolving research, policies and performance data change. The trainings are designed to provide private and public sector administrators, consultants, architects, planners and administrators with up-to-date information and state-of-the-art techniques. The program emphasizes the standards in New York State, based on NYS-DEC’s August 2010 Stormwater Design Manual, the NYS-DEC Erosion and Sediment Control Manual, FEMA flood standards, and related permits, and also examines national standards and future trends. All trainings emphasize applications to real-world conditions, and involve hands-on, group, and individual exercises.

Trainings for the workshop series include:

Wet Pond Design – 2/21/2019

Stormwater Ponds have proven to be one of the most popular stormwater management practices employed by designers. And with good reason:ponds are one of the few practices that provide both water quality and quantity treatment. This class will examine the various components of a wet pond system, and review the numerous design elements needed for proper operation of ponds. Working with a specific pond site, we will begin by establishing the tributary drainage areas and its associated hydrology. We will then determine the various pond storage volumes and finally complete the design of an outlet structure to manage the flows. The pond design will follow the uniform sizing criteria in the NYS Stormwater Management Design Manual. Hydrology will be computed using TR-55 methods.

Floodplains and Watershed Hydraulics – 3/21/2019

As climate change continues to influence flooding conditions, it is important to be able to adequately model and predict flood plains and floodways. The HEC-RAS computer program is a powerful tool developed by the USACE to model river, stream and reservoir hydraulics, and is used by FEMA to create the regulatory FIRM’s for each community. This workshop will provide a hands-on introduction to using the HEC-RAS modeling techniques to generate hydraulic profiles and to analyze and map flood plains and floodways, using actual site conditions.

Specific discussion and exercise topics will include:

  • Floodplain and hydraulics terminology
  • Intro to the HEC-RAS model
  • HEC-RAS input and output data
  • Generation of a hydraulic profile of a simple stream
  • Modeling bridges and culverts
  • Establishing floodplains and floodways

Stormwater and the Multi-Sector Permit – 4/17/2019

NYSDEC’s Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activities has just been recently updated. The first time offering of this course will cover all the basic requirements and regulations of the MSP, as well as the changes that have been made to the latest version of the permit. The class, which will be co-presented with NYSDEC and Andy Sansone of Monroe County, will review the specific MSP sectors, SWPPP preparation, and BMP’s. The preparation of the necessary forms to obtain MSP permit coverage (NOI, ACR, and Representative Outfall) will be presented, and the relationship between the MSP and the MS4 permit will be explained. Specific sector, site, and BMP design examples and problems will be provided.

Cost (which includes lunch and materials) is $260 per person, per course, if registered by the deadline; $320 per person, per course after the deadline. Special rebates are offered for municipalities. Deadline for registration is one week prior to each course. All classes are held from 8:30 a.m. until 4:45 p.m. at Cornell Cooperative Extension Orange County, 18 Seward Ave., Third Floor, Middletown, NY 10940.
