Inspector Exam Questions With
Verified Answers
\.4 factors influencing erosion - Answer- climate
groundcover (influenced by humans)
soil properties
topography (influenced by humans)
\.county use bonds - Answer- returned within 60 days of adequate stabilization
can't be more than 25% of estimated cost
to cover expenses should the applicant fail conservation action
\.Describe MS-19 after July 1, 2014 - Answer- Requires management of post-development
SW runoff if not under SW program
-If SW into a natural channel, then achieve energy balance
-If into a manmade channel, EB or max 2-yr storm discharge
-If into restored channel, EB or peak discharge is designed parameters
\.Erosion Impact Area - Answer- area of land NOT ASSOCIATED with a current land- disturbing
activity but contributing to sedimentation
