facility, as discussed in Section 8, should be considered in planning the
layout. Detailed siting criteria for specific electronics facilities may be
found in the appropriate Naval Shore Electronics Criteria Manual, 0101 Series.
Antenna spacing and siting, which usually receive first consideration, are
discussed in NAVELEX 0101,104, HF Radio Antenna Systems; the locations of
buildings are determined in relation to the antenna locations.
Operating buildings, such as transmitter and receiver buildings,
and the terminal point of transmission lines should be as near the center of
the station or antenna field as possible. Support buildings should be near
the station boundary. Where radio interference is a problem, locate roads and
parking areas so that traffic will not interfere with reception at receiver
stations. Insofar as operating and security requirements permit, buildings
should be oriented to provide maximum economy in heating and cooling and to
keep paving to a minimum. Figure 1 is a schematic representation of a typical
major communication station system.
Site Security Considerations. Facility layouts must be compatible
with an overall installation security plan and must consider the location of
guard posts, patrols, and security response forces; the location and
characteristics of intrusion detection systems; facility access control; and
natural factors. Security factors that influence exterior layouts are
discussed in MIL-HDBK-1013/1, Design Guide Lines for Physical Security of
Fixed Land-Based Facilities. Security at electronic facilities is discussed
in greater detail in Section 6.
Surface and Subsurface Drainage. The requirements of NAVFAC DM-
5.03, Drainage Systems, shall apply, except as follows:
Runoff. Calculation of storm water runoff shall be based on a
storm with a 50-year design frequency.
Pipes. Metallic pipe and reinforced concrete pipe are
inappropriate at some sites. Their use will be determined by project
Drainage. Swale drainage shall be used to the greatest extent
possible. Minimal design velocities shall be maintained to avoid damage of
Exceptions. Storm drain pipe shall not be used through an antenna
Paved Areas. The requirements of NAVFAC DM-5.5, General Provisions
and Geometric Design for Roads, Streets, Walks, and Open Storage Areas, shall
govern, except as follows:
Traffic Areas. Parking areas, pedestrian walks, and other traffic
areas adjacent to buildings shall be surfaced with bituminous concrete or
portland cement concrete.
Roads. Access roads shall be all-weather roads, with surface
courses adequate for design traffic loads.
