For those professionals involved in Stormwater management, keeping up with the latest trends and standards can be a challenging task. New techniques, standards, and regulations are evolving as research, experience, policies and performance data change.

This series of Stormwater trainings is designed to provide private and public sector engineers, architects, administrators, planners and consultants with up-to-date techniques for understanding, evaluating, designing and reviewing Stormwater management plans and practices. The program emphasizes the standards in New York State, based on NYS-DEC’s January 2015 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. NOTE: Registration with payment is required. Deadline for registration is ONE WEEK prior to each course. 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. Discount of 10% when registering with payment for all four training courses by January 10, 2020.

PDH’s, LU’s, and CEU’s have been requested for each course. The course provides 7 contact hours for landscape architects towards their CEU credits. Code Enforcement Officer Credits may be available for some courses. Questions? Contact Erik Schellenberg at or 845-344-1234. Register online or contact Marie at 845-344-1234 or or call 845-344-1234.

Green Infrastructure - Wednesday, January 22, 2020

Deadline: January 15, 2020

Green Infrastructure (GI) practices have become the newest stormwater management tools. Even though it may still be considered an evolving technology, the benefits of GI over more conventional “hard” management techniques are well known. In particular, GI’s ability to reduce runoff and provide climate change resilience has been firmly established. Many GI practices are now in place, and are performing with varying levels of success. Future design can benefit from some of the “lessons learned.” This class will examine the design details, practical applications, and critical elements of the various GI practices that are necessary for long term performance. 

 Re-Development and Retrofits - Wednesday, February 19, 2020

Deadline: February 12, 2020

This class will cover two specific applications of stormwater Management and Land Planning: Redevelopment and Retrofits.

Redevelopment: Chapter 9 of the NYSDEC Stormwater Management Design Manual is dedicated to the unique design standards on re-development sites. The section of the class will provide design examples, class exercises and case studies.

Retrofits: The class will explore the numerous retrofitting opportunities and the techniques that can be employed to transform the conventional, hardscapes of developed areas to a more resilient form. Design examples, class exercises and case studies will be presented along with the components of a successful municipal retrofitting program.

The Stormwater Construction Permit - Wednesday, April 1, 2020

Deadline: March 25, 2020

The Stormwater Construction permit is the template for designing Stormwater Pollution Prevention Plans (SWPPPs) for development projects. This comprehensive class will guide participants through the many permit conditions and requirements pertaining to various development scenarios, as well as the steps of site planning, design, evaluation and reporting necessary for obtaining NYSDEC stormwater permit coverage in New York. The class will begin with a thorough review of the latest version of the permit by NYSDEC personnel from Central Office.Then, beginning with the evaluation of pre-developed conditions and project objectives, the sequential process of site planning, stormwater practice selection Erosion & Sediment Control designand SMP design will be reviewed. Hydrology computations for WQv, CPv,OBv,ExSv, and RRv will then be covered. The class will conclude with a review of the SWPPP outline, the Notice Of Intent (NOI), and the establishment of maintenance programs. The class provides a unique opportunity for participants to interact directly with the regulatory agency on issues relating to the NYSDEC SPDES General Permit for Stormwater Discharges from Construction Activities Permit and Stormwater Management Design Manual.

Minimum Measures 3 and 6 and the MS4 Permit - Wednesday, April 22, 2020

Deadline: April 15, 2020

Two critical obligations –known as Minimum Control Measures/MCM- required by the NYSDEC SPDES General Permit for Municipal Separate Storm Sewer System (MS4) operators are to prevent illicit stormwater discharges within their jurisdiction (MCM 3 – Illicit Discharge Detection and Elimination; IDDE), and to prevent pollution from municipal facilities and operations (MCM 6 – Good Housekeeping and Pollution Prevention; GH/PS). Although simple in their objectives – to detect and eliminate non-stormwater discharges to the MS4 through mapping and continuous inspection; and, prevent stormwater pollution from facilities and field operations, to the maximum extent practicable- have broad applicability and complex, technical aspects to achieving compliance.This class will focus on the fundamental requirements of both MCMs, including proven strategies for compliance, as well as highlight some of the more advanced strategies and technologies being applied to attaining compliant IDDE and GH/P2 Permit Programs at economies of scale and cost.

This class co-instructed with Andy Sansone of Monroe County, will review the elements ofsuccessfulmunicipal IDDE and GH/P2 programs , with case studies, design examples and class and field exercises.

DEC personnel from Central Office will also be present to provide a brief update and summary of the pending updates to the MS4 general permit.


$260 per person, per course, if registered by the deadline; $320 per person, per course after the deadline. Discount of 10% when registering with payment for all four training courses by January 10, 2020.
