(3) Setbacks (see figure 4-1).
(4) Facility Proximity. A building should be located in accordance with its spatial and
functional relationship to its support facilities and to other primary facilities.
(5) Buildable Area. The buildable area is that area established on the site survey for
the location of a structure or structures determined in the site analysis and the following
guidance (see figure 4-1).
b. Environmental Factors. The location and condition of such elements as geology,
soils, drainage, and vegetation may create areas that should be excluded from development
because:
(1) They are unbuildable for structural, economic or environmental reasons.
(2) They require protection.
(3) They require preservation.
c. Orientation Factors. Building location may be influenced by orientation to enhance
energy conservation.
(1) Solar. Energy conservation criteria is provided in the AEI. Life Cycle Cost
Analyses (LCCA) should be provided as required. Special energy conservation studies for
nonrenewable resources should be accomplished as required. As illustrated in figure 4-2,
these analyses and studies should provide an orientation for facilities to be energy efficient.
(2) Other Siting Factors. Other site-specific conditions can influence building
alignment.
(a) Ability to accomplish the mission.
(b) Ability to minimize travel time.
(c) Ability to control access.
(d) Orientation to a slope (figure 4-3).
(e) Orientation to take advantage of or reduce the impact of prevailing winds
(figure 4-4).
(f) Microclimate impacts.
d. Visual Factors. The visual survey accomplished during the site visit should provide
requirements to reduce negative visual impressions. The elements to be retained or enhanced
should be included in the design. The AEI and IDG provide additional guidance (figure 4-5).
4-3. VEHICULAR CIRCULATION AND PARKING. Circulation should promote safe and
efficient movement of vehicles and pedestrians. Maintaining maximum separation of vehicles
