NYC’s Approach to Private Property Green Infrastructure

New York City is on the precipice of a major expansion in the amount of stormwater managed on its private properties. This expansion is a result of new innovative incentives and new performance-based stormwater rules. These next generation tools are the culmination of lessons learned over the last ten years of implementing the New York City Green Infrastructure Program and the rapid depletion of opportunities to retrofit publicly owned property. Private property green infrastructure implementation remains the largest challenge facing the Program, but also provides the greatest opportunity for future large-scale increases in onsite stormwater capture. Private property participation in the Program is critical to its success. Private property owners hold more than 50% of NYC’s land area. This presentation explores the next generation of NYC’s incentives and regulations to propel the private sector into participating in NYC’s water quality goals.
