b. Shape exposed soil areas to permit runoff with minimal erosion.
c. Thoroughly moisten surfaces as required to prevent dust nuisance to occupants of existing
building, public, neighboring buildings, and concurrent performance of other work on site.
d. Install safeguards to prevent water pollution from haul roads, work platforms, or other temporary
construction facilities.
e. Inspect, repair, and maintain erosion and sedimentation control measures during construction
until permanent vegetation has been established.
f. Failure to comply with established erosion control measures will result in withholding of progress
payments.
3. Trees and shrubbery to remain or to be relocated:
