Wow, tough crowd. A transition area is an area between residential and some other more intense use, such as commercial or industrial. For instance, Battery Park has traditional residences on one side, industrial on two sides (one industrial building has since been converted to lofts), and railroad tracks and the lake on the fourth side. The developer built detached homes on the street facing the older traditional homes and then attached townhouses further in. The W. 117th St. proposal again is an area of transition with commercial on the back side, it is also a block to itself, and has townhouses across in Lakewood. The fact that some doubles or apartment buildings are in my area does not make this an area of transition. Those structures are historic existing conditions, but should not effect our modern zoning districts and laws.
My neighbors and I are not against development, but think it should be done with an eye towards the quality of life of residents, and its fit with the character of the neighborhood. Twelve units is just too dense for this site. Neighborhood concerns include quality of life, privacy, peaceful enjoyment, property values and fit with the character of the neighborhood. While abutting properties will of course be the most dramatically affected, it will also affect the neighborhood as a whole. How would you feel about a three story wall of townhouses with rooftop stairway penthouses and decks being built along your property line, taking away any privacy, and increasing traffic, noise and other nuisances? I think everyone would take steps to protect their home, and their quality of life...
