or sabotage.

STORM DRAINAGE. Design the storm drainage system, including
gutters, drains, inlets and culverts, to carry the anticipated runoff, including runoff
from melting snow. Provide inlets where necessary to intercept surface flow.
The building up of undeveloped areas may have a noticeable effect on
installation drainage facilities; major alterations of extensions to storm sewers
and drainage channels may be required because of the location and design of
new facilities.
2-15
WATER SERVICE. Provide water service loop with proper valving
to maximize reliability.
2-16
SANITARY SEWER. Coordinate hangar elevations with the
existing sanitary sewer elevation to avoid the need for ejection pumps where
feasible. Capture oily wastewater contaminants from the hangar bay trench
system with oil/water separators.
2-17
AFFF CONTAINMENT. Runoff from the hangar bay (OH space)
trenches during activation of the AFFF system should be automatically routed to
a containment system. Overflow from the containment system should be
discharged to either the sanitary sewer system or the storm drain system as
directed by the department overseeing environmental policy for the installation.
Conditions for disposal will depend upon the capability and location of the facility
that would treat the effluent from the discharge site.
2-18
VEHICULAR AND PEDESTRIAN CIRCULATION.
2-18.1
Street System. Coordinate design of the street system with the
overall traffic circulation plans for the installation as well as the adjacent road
system. Provide convenient and safe vehicular access and circulation for
essential services, such as deliveries, trash and garbage collection, fire
protection, and maintenance and repair. Through traffic should be kept to a
minimum. Design in accordance with criteria set forth in UFC 4-010-01.
2-18.2
Sidewalks. Design sidewalks to provide convenient and safe
pedestrian access and necessary circulation. Base the width of walks on
pedestrian traffic volume and accessible route criteria set forth in the current
versions of the UFAS and the ADAAG. The grades of walks will normally follow
the natural pitch of the ground except at locations where physically disabled
access is required.
