The Onondaga County Save the Rain Program

200 Completed Projects in 10 Years – Lessons Learned and Success Stories

Presentation Overview:

This webinar is focused on the lessons learned and success stories from the construction of over 200 GI projects to date.

Since January 1999, Onondaga County, New York has been complying with an Amended Consent Judgment (ACJ) which includes control of combined sewer overflows (CSO) to the tributaries of Onondaga Lake.

In November 2009, the ACJ was again amended to incorporate green infrastructure (GI) strategies to further reduce wet weather from entering the combined sewer system (CSS). This is the first court order in the country to require the use of green infrastructure. The new program was entitled Save the Rain.

Since 2009, Onondaga County has constructed over 200 projects on a fast track basis, including a wide range of GI technologies. These projects capture more than 130 million gallons of stormwater annually.

Case studies from specific projects will be provided and the following key subject matters will be covered:

  • An overview of the Save the Rain projects constructed to date including the various GI technologies utilized (porous pavements, bioretention, green roofs, infiltration practices, enhanced tree planters, etc.)
  • Advantages and disadvantages of GI technologies and products from ten years of GI implementation and construction in various environments
  • Success stories from the construction of GI, from the standpoint of construction and long-term performance
  • Monitoring results of three distinct GI projects during several varying rainfall events.

Learning Objectives:

  • Learn about the advantages and disadvantages of different GI technologies.
  • Understand what we have learned about construction methods and performance.
  • Find out what we have learned from monitoring over 10 years
