MIL-HDBK-1027/4A
Outdoor pedestrian-oriented spaces are often useful for building
entry plazas, for break and lunch areas, and to provide pleasant views from
the building interior. Design outdoor areas to harmonize with the
architectural and natural site character of their surroundings, but to also
moderate environmental and climatic extremes, such as noise, sun, wind and
seasonal precipitations.
3.2.3.1
Site Analysis and Development Concept. If the analysis and
development is successful, the biological integrity of the site will be
retained or improved, while successfully meeting the program needs of the
user in a comfortable, attractive and functional setting. Minimize clearing
of existing vegetation and avoid excessive grading.
3.2.3.2
Planting. Guidance for planting design is provided in NAVFAC
P-905, Planting and Establishment of Trees, Shrubs, Ground Covers and Vines.
Plantings can provide a pleasant setting and visual asset, and minimize the
environmental impact of development. The following is a list of minimum
guidelines to be considered in implementing new planting schemes for the
facility:
a) Preserve Existing Vegetation. Existing mature stands of trees
or other significant vegetation are to be preserved and enhanced, where
possible.
b) Select Indigenous Plant Materials.
Plant materials chosen will
be indigenous to the site.
c)
Design for Minimum Maintenance.
d) Define Space and Screen Conflicting Uses. Select plant
material to define space and screen visually conflicting uses, where
appropriate. See section on screens and walls below.
e) Promote Energy Conservation. Plant materials are to be used to
reduce energy requirements, where possible, such as shading with deciduous
trees. Enhance any desirable climatic effects, such as clear areas at large
glass areas oriented for winter sun heat gain.
f) Establish Unifying Elements.
Provide planting as a means to
unify different elements of an installation.
3.2.3.3
Landscape Lighting. The creative use of lighting can greatly
improve the visual character of a project landscape, while providing the
nighttime functions of safety, security and path finding. In addition to
simply achieving a higher level of illumination, the lighting levels, color,
patterns and style should be energy efficient, attractive and functional in a
coordinated landscape scheme.
3.2.3.4
Exterior Signs.
Conform to requirements of the BEAP.
3.2.3.5
Utilities. Grouping in corridors, underground placement, and
screening and grading can de-emphasize the impact of utilities on a site.
Flow tests must be conducted to determine the available water supply for fire
protection. Indicate a static pressure and a residual pressure at a certain
flow.
