   -existing and new slopes
   -drainage area and patterns
   -hydrology
   - soil types
2. Resources
   -onsite vegetation to protect
   -onsite/offsite water bodies to protect
   -Pre-existing improvements to protect and use
3. Risk

2. Plans for phasing and sequencing (work)
3. Plans for diversion and dewatering (water)
4. Plans to limit and delay disturbance (sequencing)
5. Plans to achieve permanent stabilization (erosion)
6. Plans to capture sediment during active work (sediment)

Question 7

7 phases of construction?

Answer 7

Preserve as much existing veg as possible

Question 9

BMP for mass grading phase?

Answer 9

Principle basins, traps and barriers

Question 10

BMP for site access and off-hauling phase?

Answer 10

Stabilize and limit ingress/egress points

Question 11

BMP for mass grading phase?

Answer 11

Stabilize basins, manage concentrated run on and runoff through the site

Question 12

BMP for channel construction?

Answer 12

Monitor weather, install grade controls, stabilize stream banks early

Question 13

BMP for final stabilization phase?

Answer 13

Apply temporary or permanent stabilization measures immediately on disturbed areas

Question 14

BMP for vertical construction phase?

Answer 14

• Protect existing measures
• modify plans to show new conditions and updated measures

2. inspect and maintain the practices
3. maintain records of activities
4. Update the SWPPP
5. Respond to spills
6. Ensure plan is accessible
