This document discusses green infrastructure approaches for ecosystem and water resources restoration, including alternative cul-de-sacs, stormwater planters that provide pollutant uptake and peak flow reduction, and bioswales in rights-of-way. It also references NYC green infrastructure design criteria and shows photos of preserved historic roads and a water table map with groundwater flow arrows. The presentation encourages the use of green infrastructure as an alternative to traditional infrastructure development.

• Vegetative uptake of
stormwater pollutants
• Pretreatment for
suspended solids
before they reach water-
treatment facilities
• Aesthetically pleasing
• Reduction of peak
