ANY CONSTRUCTION THAT WILL RESULT IN DISTURBED AREAS ON OR WITHIN A CRITICAL AREA OR ASSOCIATED BUFFER, SHALL BE SUBJECT TO THE "CRITICAL AREA RESTRICTIONS" CONTAINED IN THE ESC STANDARDS. THESE PROVISIONS INCLUDE PHASING THE PROJECT WHENEVER POSSIBLE SO THAT CONSTRUCTION IN THESE AREAS IS LIMITED TO THE DRY SEASON. 2. DURING CONSTRUCTION, ESC PLANS SHALL BE REVISED AS NECESSARY BY THE ESC SUPERVISOR OR AS DIRECTED BY THE CITY TO ADDRESS CHANGING SITE CONDITIONS, UNEXPECTED STORM EVENTS, OR NON-COMPLIANCE WITH THE ESC PERFORMANCE CRITERIA IN SECTION D.4.1 (P. D-69). IF NON-COMPLIANCE WITH THE ESC PERFORMANCE CRITERIA OCCURS, THE PLAN MUST BE UPDATED WITHIN 48 HOURS (FAILURE TO DO SO COULD RESULT IN A "STOP WORK" ORDER AS DETERMINED BY THE CITY INSPECTOR) OF INSPECTIONS OR INVESTIGATIONS. IMPLEMENTATION OF THE ONSITE CHANGES MUST OCCUR WITHIN 5 DAYS. 3. ALL ESC MEASURES SHALL BE MAINTAINED AND REVIEWED ON A REGULAR BASIS AS PRESCRIBED IN THE MAINTENANCE REQUIREMENTS FOR EACH BMP AND IN THIS SECTION. THE ESC SUPERVISOR SHALL REVIEW THE SITE AT LEAST WEEKLY DURING THE WET SEASON, AND WITHIN 24 HOURS OF SIGNIFICANT STORMS. IN GENERAL, A SIGNIFICANT STORM IS ONE WITH MORE THAN 0.5 INCHES OF RAIN IN 24 HOURS OR LESS. THE CITY MAY REQUIRE THAT A WRITTEN RECORD OF THESE REVIEWS BE KEPT ON SITE WITH COPIES SUBMITTED TO THE CITY WITHIN 48 HOURS. GLADCO DEVELOPMENT, L.L.C.
