  5. Post a copy of the construction site notice (CSN) at the site entrance .
  6. Complete the site inspections at least once every 7 days OR at least once every 14 days AND after a rain event of 1/2" or more. (Some local agencies may require more stringent inspection frequencies; such as weekly AND post rain inspections.
