Things to Memorize Flashcards
One acre =
43,560 square feet
Site Slope Percentage = Vertical/Horizontal x 100
flat area - good for all activities =
moderate=
steep,unusable=
very steep, subject to erosion=
flat area - good for all activities = <4%
moderate = 4-10%
steep, unusable = 10-50%
very steep, subject to erosion = +50%
Construction Slope Percentage = Vertical/Horizontal x 100

planted banks =
parking area/lot =
automobile ramps =
sidewalks =
street/paved driveways =
storm drains =0.3%
sanitary sewers = 0.4 - 1.4%
street surface drainage = 0.5% min
planted or large pavers = 1% min
lawns = 25% max
planted banks = 50% max
parking area/lot = 5% max

Eight basic categories of use:
1) Agricultural
2) Commercial
3) Government
4) Industrial
5) Institutional
6) Natural Resources
7) Open/Conservation
8) Residential
4 types of soil:
1) Gravel: well drained and able to bear loads (+2 mm)
2) Sand: well drained and can serve as foundation when graded (0.5 - 2 mm)
3) Silt: stable when dry, swells when frozen, do not use when wet (.002 - .05 mm)
4) Clay: must be removed, too stiff whe dry and too plastic when wet ( < .002 mm)
levels of soil
A level = topsoil
B level = minerals
C level =
Partially weathered/fractured rock
D level = bedrock
survey diagram
Building Efficiency =
Net Area/Gross Area
Floor Area Ratio (FAR) =
Gross Area/Site Area
Net Area =
measured from inside walls
Gross Area =
measured from exterior face of walls
True or False,
Penthouses, fan rooms, and skylights are sometimes allowed to exceed height restrictions.
True
Most efficient layout for parking are
90° perpendicular spaces, which allow for the maximum amount of spaces and two way traffic
The cheapest parking to build is …
… an outdoor lot, then a parking structure, then underground parking
