GENERAL DESIGNS CONSIDERATIONS
DG 1110-3-112 May 1979
3-3 SITE DEVELOPMENT (cont'd)
b. PEDESTRIAN AND VEHICULAR SYSTEM. A safe and convenient pedestrian and vehicular
system must be established. The system should separate pedestrian and vehicular activities as much
as possible and incorporate requirements for the physically handicapped in accordance with EM
1110-1-103.
(1) Walkways. The pedestrian system is essentially established by the pattern of walkways
designed to support access and egress to and from usable entrances of the ACES Center. Generally,
walkways should be designed to complement the natural flow of pedestrian traffic, be 6' wide, and
slope no more than 1 in 24 blending to a common level with other surfaces. Where significant level
changes are required, both steps and ramps should be provided. Walks crossing roadways must be
marked and provided with curb ramps, if curbs are used.
(2) Roadways. Vehicular arterials should not run through the ACES Center grounds or between the
Center and closely related facilities such as the library. A pedestrian drop-off and pick-up zone should
be provided near the main entrance to the Center, and be designed to be barrier free.
(3) Parking. A principal part of the vehicular system involves parking facilities for the cars and
motorcycles of students and staff. The number of parking spaces required shall be based on a traffic
analysis at the installation, taking into consideration time and space intervals related to the ACES
instructional activities, and available mass transportation, car pooling, etc. A portion of the car parking
spaces will be designed for use by handicapped drivers and carefully located to avoid having to cross a
roadway to gain access to the building. Parking should be orderly and if possible dispersed and
accented with landscape features.
(4) Service Access. Service roads and areas should be separated whenever possible from
pedestrian oriented roadways, parking and walkways. In the outside areas related to vocational
training; service requirements, car storage and parking may be combined. However, it is essential that
the vehicular system provide access for fire fighting equipment, trash removal and other servicing
equipment as well as for deliveries. Service areas and service roads must be sized to accommodate
the turning radii and maneuvering requirements of the largest vehicles. At the same time, the extent of
paving should be minimized. Screening for service areas should be accomplished in conjunction with
the screening of utilities features.
c. LANDSCAPING AND SIGNAGE PLAN. In conjunction with establishing the building-site
relationship and the pedestrian-vehicular system, a landscaping and signage plan will be developed.
(1) Signage. Direction signs and signs identifying buildings, parking areas, service areas, and
facilities for the handicapped are required and shall be developed as an overall system together with
the signage required for the building. Design shall conform to the signage criteria discussed under
Building Design.
