public works departments may be utilized for consistent
appearance or for ease of construction.
3.2.3.3.5 Aprons should be sized to allow parking of at least
one vehicle; the apron size will depend upon the typical vehicles
for the location. Aprons at loading docks, dumpster pads and
wash bay platforms shall be sized to incorporate the areas in
which concentrated wheel turning movements of heavy vehicles
or trucks occur and where heavy wheel loads repeatedly occur.
Aprons outside maintenance shops workbays must be concrete,
and 11 meters (36 ft) long.

3.2.3.4 Additional Paving Considerations
Parks, California
3.2.3.4.1 Some recommended sustainable design measures are
intended to reduce heat islands, including use of light-colored
materials for impervious surfaces, or open grid pavement
systems. Open grid modular paving units are available on the
commercial market and may be investigated for use, but the
availability and cost of these systems may vary widely based on
locale. Practicality and serviceability of this type of system in
snow areas should be carefully considered.
3.2.3.4.2 Special aggregates, toppings and coatings other than
typical maintenance items (seal coatings, sealers) may be
considered, but these may have high initial or maintenance
costs. PCC is light in color, but usually introduces a substantial
cost increase over AC pavement. Alternate pavement design,
such as "resin modified pavement" may be used in special
cases, cost control and quality control parameters can be
achieved. Resin modified pavement is suitable for fuel resistance
on aprons that are nearly flat. Machine finished pavement is
slick when wet.
3.2.4 Civil Layout
3.2.4.1 Roadway Geometrics
checked for adherence to the AT/FP requirements for spacing
and setbacks at buildings. Consideration in design should also
be given to the using vehicles from off-site sources, such as
delivery trucks and maintenance or service vehicles.
3.2.4.1.2 Geometrics at the access drive will need to be
coordinated with the agency responsible for the public or
Government installation roadway which is being accessed. If
