Demand the NO ACTION option for SNAD
August 27th, 2019 Posted in Environmental Reviews, Front Page News, Green Infrastructure, Harlem River Working Group, Hudson River Watershed Projects, Living Ecological Green Infrastructure, Low Impact Development, NYC Parks Department, Project Green, Resiliency and SustainabilityThe Special Natural Areas District (SNAD) in the Bronx is being changed by City Planning.
The proposed change would allow construction of impervious surfaces and lawns within buffers can impair buffer function by clearing trees, altering existing wetland hydrology, and increasing thermal impacts. As you know, grass lawns and landscaped areas can hamper infiltration, increase storm water runoff velocity and, due to residential and/or commercial fertilizer use, dramatically increase nutrient loading to wetlands and waters.
The proposal would relax restrictions and allow widespread development in areas previously determined ecologically sensitive, such as Alder Brook, Harlem and Hudson Rivers, Riverdale and Raoul Wallenberg Parks.
It would allow development on properties of less than one acre in affected areas to avoid City Planning review and the public participation which it entails, in favor of Buildings Department approval.
Finally, it would allow community facilities to build more and preserve less than what is required of homeowners, and eliminate environmental review for certain institutional projects.

Thank you
We want to thank you for helping to preserve and restore our environment. The City of New York is already 72% impervious! The Bronx side of the Harlem River Watershed is 66% which is better but more can be done. We estimate that the SNAD is about 50% but that is not mentioned in the DEIS. (CEQR 19DCP083Y)
We can classify stream quality levels by percent imperiousness. Streams in an area of ranging from 1 to 10% impervious cover are “stressed streams.” In 11 to 25% impervious cover areas, streams are impacted. And in areas of 26 to 100% impervious cover, streams are degraded. In fact, research indicates that watersheds are demonstrably and irreversibly degraded when as little as 10% of their surface area is covered by impervious surfaces.
