as porches, main entrances, and decora-
tive details. The street or sidewalk is
also where the public most often views a
building.
       Work to the rear of a building is
usually reviewed with more flexibility
since it is generally not visible due to
the building’s placement on the lot or
screening by landscape or fences. The
rear of a building is the most appropriate
location for the construction of additional
living space or other major alterations.
Buildings on corner lots are the excep-
tion. Because the rear of a building on a
corner lot is visible from the street, it will
be reviewed with the same provisions for
the sides of buildings.

   Guidelines
Site and Setting


A     urora’s Historic Districts and
      Historic Landmarks developed
from the mid-19th through the mid-20th
centuries. Most blocks in the Districts
retain their original character of site and
setting. In residential neighborhoods
dwellings were built with consistent
street setbacks and with front yards for
landscaping. Typically with the house’s
porch and main entrance were oriented
towards the street. Blocks were laid out
with similar lot dimensions and distances
between houses, creating a consistent
rhythm and pattern in the location of
buildings and the intervening spaces.
      In the downtown areas, commercial
buildings are found that were laid out
and built to form a continuous façade
close to the sidewalk. The consistent
setbacks and similar lot widths set up the
rhythm of the streetscape in these com-
mercial blocks.
      These streetscape characteristics are
retained on most blocks in the Districts
and should be preserved and maintained.
      The following guidelines provide
information on changes and alterations to
a property’s site and setting that could af-
fect not only its architectural appearance
but also that of the District.

B. Ramps should be located at the rear or
   sides of dwellings. If a ramp is placed
   on the front of a building it should
   be of wood construction rather than
   of brick, concrete, or metal. Brick,
   concrete, and metal ramps are more
   acceptable at rear and sides of build-
   ings with interior lots.

C. Ramps should be of simple traditional
   design and configuration or designed
   to match the original porch railing in
   materials, dimensions, and detailing.
   Ramps should be painted to match the
   color of the porch railing or to match
   the overall paint color of the building.

D. Ramps in visible areas should be
   screened with landscaping.

E. When required by code, ramps shall
   adhere to applicable Historic Preser-
   vation provisions of the accessibility
   code.
