LDP - -Land Developing Projects - altering
landscape for projects such as agriculture or
housing ect. Large Land Development - --strips off all
existing vegetation a.k.a site carving
-usually on hillsides and steep slopes
-installation of untilities that tear up large areas of
NPDES - -National Pollutant Discharge land
Elimination System
- section of the CWA (Clean Water Act) to permit
stormwater discharges associated w industrial Vertical Projects - -- Homebuilding, smaller
activities PER permit residence construction projects
-usually multiple subcontractors
-requires lots of housekeeping = mass choas
CWA Penalty Types - -Adminstrative
Class I. Neglegent
Class II. Knowlingly = greater fines Bix Box Projects - --commercial buildings
-mass grading and mass choas
-highly visible w/ fairly large footprint
What documents are required on site? - --
SWPPP
- CGP Linear Projects - --roadways, utilities, and
- Site Map stream corridors
- Drawings and Key -long narrow sites and mass choas
- All inspection reports -limites site access and continually changing
- Any amendments to SWPPP (high activity)
Who is the "operator"? Also the LRP. - - What is erosion? - -The process by which
Usually the OWNER of the site, not the soil particle get displaced by the act of wind of
contractor, unless authorized by the owner to water.
general contractor to have day-to-day
operational control!
What are the three types of Wind Erosion? -
-1. Creep - causes sand dunes
When do you need permit coverage? - - <10%
Required from start to end of project. "End" being -large particle that roll across a terrain
the final vegetative/non-vegetative (concrete)
stabilization occuring. 2. Saltation - bouncing particles that DISLODGE
more particles, then fall back down
For any project one acre or greater. ~50-80%
- stay relatively close to ground

3. Suspesion - suspended way up into the
atmosphere What factors impact rainfall erosion? - --
~ 5-25% Climate events
-light weight soil particles dusted in the air -Soil erodibility
-The length of flow over a distance/ How Far
-Rate of flow
-The angle of the slope
Which method of wind erosion moves the most -Vegetative cover
soil? - -Saltation -Erosion and Sediment controls (BMPs)
What are the types of water erosion? - - What is Sediment? - -The eroded material
Raindrop erosion that settles in water or air.
Sheet erosion
Rill and Gully erosion
Stream and Channel erosion
What is sedimentation? - -The process by
Shoreline erosion - by the act of waves which eroded soil particles in water or air are
Landslides - difficult to prevent deposited in NEW locations.
Raindrop Erosion - -dislodges many soil Rate soils from Most Erodible to Least. - -1.
particles Silt = big particle/more erodible k~0.57
2. Sand/Loam = medium
3. Clay = very small particles/least erodible
k~0.10
Sheet Erosion - -stripping away a thin
sheet of topsoil from the surface of the land
-flat lands where water flows ontop due to runoff
-can transport large amounts of soil Which direction does water flow? - -High
-causes additional erosion points to low.
Through the mouth of the "V" from the back- up.
Rill and Gully Erosion - -If the runoff is
allowed to concentrate and gain velocity or
energy, it will cut rills and gullies as it detaches Basin divides - -Separates flows
more soil particles -water that goes from low point to high. To extend
the time of concentration
Rills: < or = to 3in. deep
Gullies: Three of more rills that convered to
greater than 3in. deep
What is a hydrograph? - -a "picture" of
2/7
