Performance standards
(a) Flexible and creative lot layout and site design is encouraged to promote a mix of residential, commercial, office and public uses in a vibrant pedestrian oriented environment. The following performance standards delineate provisions for site development for uses permitted in the various sub-districts in the waterfront district. Performance standards for adaptive reuse projects are contained within subsection (b) following the table below.
The intent of the performance standards is to control the location of buildings to define and contain the street space, and to concentrate and reinforce pedestrian activity. Buildings in the waterfront district should reinforce the characteristics consistent with urban waterfront areas, with "build to" lines maintained for most of their frontage at the edge of the public right-of-way.

The density proposed for any adaptive reuse project shall be determined to meet all public health and safety standards.
(3) Dimensional requirements.

b. No additional encroachments shall be permitted into any nonconforming setback unless relief is granted by the permitting authority.

Any nonresidential uses proposed as part of an adaptive reuse project must comply with the provisions of section 19-481 for the zoning district in which the structure is located.
