that is not well developed. This small exception at the edge of the density boundary
may be the cause for an exception to the summation of area densities, especially if the
density is appropriate in other areas outside the circle. This might still meet the intent
of the credit. The site itself may sometimes not meet the full density criterion, but if
perhaps taken together with other neighboring campus facilities with more than
adequate densities, it may still meet the intent. Existing single-family housing and
historic sites may not have to be included in the calculations as they are usually
considered to be valuable assets to a community. Stadiums may also be exempt if they
exist in pedestrian-friendly urban areas. In addition, future development may be used
in the calculations if there is sufficient documentation that these types of facilities will
be built, but this has not been specifically addressed in the LEED 2009 Reference
Guide.

Option 2 The submittal requirements for Option 2 of credit SSc2 include the
following:

• A site vicinity map showing the parcel and building in question (project site)
with a ½-mi-radius circle drawn from the main entrance, or the drawing scale
noted on the map. The location of all services within this circle shall be shown.
The location of the residential neighborhoods shall also be shown with the
dense residential neighborhood of at least 10 units per acre noted. Many types
of maps may be used including aerial photographs, sketches, and assessor
maps. LEED 2009 allows for consideration of multiple main entrances on single
or multiple building projects. A ½-mi-radius circle may be drawn from each of
these main entrances and the entire area within the circles considered. An
example in a very urban area of a project with a single main entrance is given in
Fig. 2.2.2.
• A listing of all the community services within this circle including business
name and type. Even though there may be multiples of many of the basic
services within this circle, only one of each type may be used for this credit,
except for restaurants, for which multiple restaurants may count for 2 of the
minimum 10 services. List only those services for which there is pedestrian
access to the site. Do not list any that are blocked by highways, waterways, and
other areas that hinder access. Up to two future developments may be used in
the calculations if there is sufficient documentation that these types of facilities
will be available within one year of occupance of the subject project. In mixed
use projects, one of the services for the project in question can be included as
one of the 10.
• The project site and building area in square feet. [See the definitions of site area
and square footage of a building (GFA) given in App. B.]

Special Circumstances and Exemplary Performance
If there are special circumstances for either of the options, a narrative must be submitted
describing these circumstances.
The criteria which must be met for exemplary performance for Option 1 were
listed under the Option 1 section. There is no EP point available for SS Credit 2
Option 2.
