entrance and windows, intake and exhaust vents) to compensate for these
adverse conditions, including snow. Consider prevailing and seasonal wind
conditions as well.

ACCESSIBILITY FOR THE DISABLED. All exterior routes to the
facility must be accessible to the disabled in accordance with the Uniform
Federal Accessibility Standards (UFAS) and the Americans with Disabilities Act
Accessibility Guidelines (ADAAG). See Chapter 3 for additional discussion
concerning accessibility requirements.

SECURITY FENCING. Limit the use of fencing to enclose and
separate areas within the vicinity of the hangar to those conditions requiring
security or the protection of life, separation of a construction site from operational
facilities, isolation of a hazardous area, or as stipulated by the Base Security
Department.
2-10
LANDSCAPE PLANTING. Make use of low maintenance
landscape plants that are indigenous to the area. Existing mature trees and
vegetation should be retained whenever practical. Landscape design should
avoid planting next to the hangar that would permit concealment in accordance
with criteria set forth in UFC 4-010-01. As hangars are generally in industrial
areas, limit landscaping to entrances and other public areas.
2-11
SOIL AND GROUNDWATER CONDITIONS. Investigate soil and
foundation conditions to assure suitability for economical excavation, site
preparation, building foundations, utility lines, grading, and planting. Test the
bearing capacity for the design of stable and economical facility foundations.
Check groundwater elevations to assure economic methods of construction on
subsurface foundations and utilities. Investigate the potential of contaminated
soils and groundwater within the site to determine if remediation will be required.
2-12
UTILITIES. Consider utilities that are essential to efficient
operation and design of adequate size to serve future requirements in the early
planning stages. Specifically address the adequacy of existing utilities support
and include any additional needs. Plan utility lines to minimize utility easements,
capital investments, and maintenance and repair costs.
2-12.1
Underground Lines. Locate underground utilities to minimize the
cost and effort of performing maintenance. Normally, utility lines of any type
should not be located under hangars, parking lots, sidewalks, and other paved
areas. Locate all underground utility lines, mains, and conduits at the minimum
depth required in accordance with local code, frost line and water table
requirements, and, when possible, in common corridors to allow for ready access
and maintenance. Locate utilities to allow for future expansion of the flightline.

SECURITY. The design, location, visibility and access should be
considered for protective construction measures to reduce vulnerability to action
