The build -to lines coincide with the street right -of -way lines in most cases, with the exception of the areas to the west of the viaduct where a required setback is noted (along 4th and 5th Avenues). In those cases, a setback up to 10' is allowed and is intended to provide privacy for ground -floor uses and to accommodate elements such as porches, stoops, balconies, landscaping and front yards. SETBACKS, STEP -BACKS + ENCROACHMENTS The street -edge property line defines the separation between the public right -of -way and the private realm. The recommended build -to lines define where buildings must be built to. A minimum percentage of the building face must be built to this line. On certain streets, such as Riverfront Street, the build -to line is at the street property line, because a continuous street wall with ground -floor retail or active uses is desirable. 4 Build -to Lines Step -back Zone Above 66' 3.10 'Setback Zone -; Exemption from ' Build do Line with ReliSe of operations Warehoose FIGURE 4 -3: BUILD -TO LINES+ SETBACKS & STEP -BACKS On other streets likely to have a more residential character, a setback of 3'to 10' allows for landscaping, front porches, stoops and balconies and is intended to provide privacy for ground floor residential units as well as allow for level changes between the sidewalk and the ground floor of the building. A step -back is a required change in the plane of the building fa4ade above a certain height. Step -backs are required on the buildings facing Riverfront Street above 60' by a 10' horizontal dimension. This allows a roof -deck or terrace at the 60' level for additional units on the floors above. On high- density opportunity sites, this step -back is required at 40' for buildings over 80' in height. Additional bulk controls also apply. Architectural elements such as balconies, bay windows, arcades, stoops and porches are permitted to encroach into the space beyond the setback or the build -to lines. Their maximum dimensions are defined in the form -based design guidelines.
