(a) Reducing slope gradients.
(b) Using geotextiles as filtering fabrics.
(c) Establishing or reestablishing vegetative cover.
(d) Introducing mechanical controls such as riprap, gabions, terracing and
cribbing.
(3) Banks with steeper than 3:1 slopes are discouraged because they increase the
rate of runoff and erosion. When an area involves steep grades, solutions such as retaining
walls should be used to reduce erosion and maintenance. Figure 4-14 illustrates methods of
erosion control.
4-6. UTILITY SYSTEMS DESIGN. Utility systems should minimize impact to the natural site
while meeting basic economic and functional criteria. The AEI provides guidance concerning
utility design. Utility systems should be located as follows:
a. Utility corridors should be used to minimize environmental disturbance and simplify
maintenance. These corridors should be located along a site's perimeter and not cross a site
diagonally or indiscriminately because future realignment of existing systems will increase the
costs of future development.
b. Utilities should be placed underground wherever possible to:
(1) Avoid conflicts with vegetation
(2) Provide protection from storm damage.
(3) Enhance the visual quality of the installation
c. To simplify maintenance, utility lines should not be placed under paved areas, but
located at the back of the roadway curb. It is extremely important to determine the potential for
future expansion and to allow for upgrading the system when locating utilities.
d. Utility transformers and transclosures for underground utilities shall be located to
ensure ease of access for maintenance but not obstruct site primary visual relationships. They
should be located with adequate setbacks from vehicular circulation and parking areas.
4-7. LIGHTING DESIGN. Outdoor lighting allows such activities as driving and walking to
continue at night under safe conditions. On most sites, only enough light to illuminate these
functions is necessary. Where physical security is a concern, more lighting may be required.
Different types of lighting should be used to meet the needs of the site. The AEI provides
guidance concerning electrical design.
4-8. LANDSCAPE DESIGN. Landscape design includes the preservation and enhancement
of the environmental and visual quality including plant material, hardscape, lighting and
signage. Landscape design is discussed in TM 5-803-13. The Installation Design Guide
provides guidelines for installation preferences and establishes goals and objectives for the
