Buffer Zones. Requirements for buffer zones, which protect the
site and adjoining communities from man-made radio noise, are described in
NAVELEX 0101,102, Radio Communications Station Design. Registry of this land
under local or state laws that restrict further development of radiation-
sensitive areas is the most desirable means of protecting the site.
Other Considerations. Because of electromagnetic hazards or
security considerations, it may be desirable to isolate buildings from
community facilities, population centers, and public transportation lines. If
hazardous conditions are absent, however, proximity to transportation and to
community recreation facilities can be desirable.
Expansion. Provide for future expansion as required by the BESEP.
If there are no specific requirements, plan for expansion as a matter of
course. Locate support facilities near the boundary of the station to permit
expansion without undue invasion of the antenna area. When the budget
permits, construction of separate structures or self-contained elements is
preferred to expansion by extension of existing facilities.
Siting Procedure. Developing the optimum site configuration
requires coordination of civil engineering and electronic engineering. The
designer will be provided with preliminary site layouts developed by the
electronic system engineering activity. These documents show the site's
dimensions, schematic building layout, utility requirements, access road
layout, direction and number of transmission paths, size and layout of
supporting structures, and special design considerations for optimum
performance of the electronic system.
Site Plan Components. Using the preliminary site layout prepared
by the electronic system engineering activity, information from the site
survey, and the criteria herein, the designer shall prepare a final site plan.
In addition to the location of facility components, the final plan shall show
the site boundary and property lines; the base line and bench marks; access
roads and parking areas; elevation, azimuth, and coordinates for the center of
each antenna; underground utilities; underground services; and existing
buildings and facilities. In general, electronic facilities (structures) are
similar to other Navy shore facilities, and the criteria in the NAVFAC design
manuals are applicable. Characteristics of specific electronic buildings and
site components are discussed in Section 8. Special considerations for
physical security and personnel safety are discussed in Sections 6 and 7.
Site development criteria unique to shore electronic facilities are discussed
Survey Base Line. The construction base line normally is
established by the siting survey performed by the electronic system
engineering activity. Special precautions are required to protect the base
line markers from movement or loss during construction.
Layout. The general location of buildings is established on the
general development map of an activity. Technical details bearing on the
location and orientation of buildings are given in the BESEP and furnished to
the designer for adaptation to the site. The arrangement of facilities at a
communication station varies according to mission. The functions of each
