Demolition shall mean any intentional or unintentional act of dismantling, pulling down,

thereof. For the purposes of demolition review as described in article IX, demolition is defined

Exception: Minor repair and routine maintenance.
Significant structure shall mean any structure or portion thereof that in whole or in part meets one

Section 5-134(h): The architectural review board shall consider the following criteria when
determining the significance, as defined in this chapter, of existing structures:
(1) Was the structure designed by a noted architect?
(2) Has the structure been listed as having historic significance by any local, regional,
state or historic agency or society?

3. (3) Does the structure exhibit characteristics of a distinct architectural style?
(4) Does the structure belong to a distinctive set of buildings, such as a single structure
belonging to a row of similar structures?
(5) Is the structure a significant part of the fabric of the community due to its age, unique
architecture, historical significance or physical placement?
Compatibility shall mean harmony with the existing neighborhood, site configurations,
development patterns, and the character of the development envelope found within the adjacent
and immediate block area, as demonstrated in the demolition review application, including roof
pitch, scale, massing, garage and driveway location and setbacks. Adjacent and immediate block
area shall include but not be limited to all properties along:
(1) The specific block where the project is proposed;

17, 2023, the Architectural Review Board considered the request and voted unanimously to
declare the existing main structure as not significant and recommended approval of the design as
compatible.
