9.
|
Bedrock greater than 60 inches below the soil surface is not considered a soil

|
|
10.
|
Fragipans and dense glacial till can limit the function of septic tank
absorption fields.
|
|
11.
|
A good sit for buildings with basements is in nearly-level or gently-sloping

12.

other body of water.
|
|
13.
|
Clayey surface soil textures are good for roads and streets because they are

|
|
17.
|
A moderately sloping soil is considered to be a 12-18% slope.
|
|
18.
|
Slopes greater than 6% can create erosion hazards that might cause driveways to

|
|
19.
|
Gray streaks found in the substratum of soils formed in glacial till and lakebed
sediments are known as mottles.
|
