Normally, this is not these forums are not the place for politics but weakening the SNAD protection in Riverdale would very clearly allow development to run rampant in a part of the neighborhood where the rock outcroppings, natural slopes, and tall old trees give a sense of the natural history of the area.
When I taught at P.S. 24, we used the rock outcroppings and boulders of Fieldston as a means to teach/learn about geology. From the sidewalks you can see evidence of plate tectonics and the movement of glaciers. We also used neighborhood trees as specimens for study (the students were intrigued to learn that the spiky thorns of Black Locust trees were very likely an evolutionary adaptation to prevent the tree from mastodons). SNAD protections have been helpful in preserving these natural elements, which are a part of the neighborhood’s character and natural history.
