REQUIREMENTS TO MEET ANTICIPATED SITE CONDITIONS. AS CONSTRUCTION
PROGRESSES AND UNEXPECTED OR SEASONAL CONDITIONS DICTATE, THE APPLICANT
SHALL ANTICIPATE THAT MORE ESC BMPS WILL BE NECESSARY TO ENSURE COMPLETE
SILTATION CONTROL ON THE PROPOSED SITE. DURING THE COURSE OF
CONSTRUCTION, IT SHALL BE THE OBLIGATION AND RESPONSIBIUTY OF THE
APPLICANT TO ADDRESS ANY NEW CONDITIONS THAT MAY BE CREATED BY THE
ACTIVITIES AND TO PROVIDE ADDITIONAL ESC BMPS, OVER AND ABOVE MINIMUM
REQUIREMENTS, AS MAY BE NEEDED, TO PROTECT ADJACENT PROPERTIES AND WATER
QUAUTY OF THE RECEIVING DRAINAGE SYSTEM.
