Chapter 3 - Special Southern Roosevelt Island District (SRI)
GENERAL PURPOSES
The “Special Southern Roosevelt Island District” established in this Resolution is designed to promote and protect public health, safety and general welfare. These general goals include, among others, the following specific purposes:
(a) to provide opportunities for the development of an academic and research and development campus in a manner that benefits the surrounding community;
(b) to allow for a mix of residential, retail and other commercial uses to support the academic and research and development facilities and complement the urban fabric of Roosevelt Island;
(c) to establish a network of publicly accessible open areas that take advantage of the unique location of Roosevelt Island and that integrate the academic campus into the network of open spaces on Roosevelt Island and provide a community amenity;
(d) to strengthen visual and physical connections between the eastern and western shores of Roosevelt Island by establishing publicly accessible connections through the Special District and above-grade view corridors;
(e) to encourage alternative forms of transportation by eliminating required parking and placing a maximum cap on permitted parking;
(f) to provide flexibility of architectural design within limits established to assure adequate access of light and air to the street and surrounding waterfront open areas, and thus to encourage more attractive and innovative building forms; and
(g) to promote the most desirable use of land in this area and thus conserving the value of land and buildings, and thereby protecting the City’s tax revenues.
