the review and approval of the County Engineer. 2. Prior to

CONCRETE DAM REMOVAL PLAN & SEQUENCING: /
A PHASE II ENVIRONMENTAL SITE ASSESSMENT (ESA) WAS COMPLETED IN ACCORDANCE WITH MINIMUM ASTM STANDARDS. THE
PHASE II ESA INCLUDES, BUT IS NOT LIMITED TO, SAMPLING AND TESTING OF ACCUMULATED SEDIMENT BEHIND THE DAM THAT / S
EXISTS ON THE PROPERTY. THE CONTRACTOR SHALL COMPLY WITH ALL RECOMMENDATIONS OF THE PHASE II ESA PRIOR TO /
ISSUANCE OF THE FIRST BUILDING PERMIT IN PLEASANT GREEN'S PHASE II. THE CONTRACTOR SHALL ALSO REMOVE
ACCUMULATED SEDIMENT FROM BEHIND THE DAM PRIOR TO DEMOLITION OF THE DAM AND DISPOSE OF THE SEDIMENT, EITHER i /
ON SITE OR OFF SITE, IN ACCORDANCE WITH WITH THE PHASE II ESA RECOMMENDATIONS. `
THE TIMING OF THE CONCRETE DAM's REMOVAL WILL BE DETERMINED BY THE CONTRACTOR SINCE THE SCHEDULE WILL BEST BE
KNOWN BY HIM OR HER. THE CONTRACTOR SHALL INFORM THE COUNTY ESC INSPECTOR AND THE COUNTY ENGINEERING /
DEPARTMENT A MINIMUM OF 5 BUSINESS DAYS PRIOR TO COMMENCING WORK. THE INSTALLATION OF THE CONSPAN STRUCTURE
AND ITS RIPRAP PLACED IN THE STREAM BED MAY LIMIT FLASH RUNOFF FROM EXISTING THE PROPERTY DOWNSTREAM, BUT THIS /
IS NOT A PREREQUISITE TO THE DAM's REMOVAL. THE DAM's DEMOLITION SHALL OCCUR FROM THE TOP TO BOTTOM SO THAT \
IMPOUNDED WATER MAY BE RELEASED MORE SLOWLY OVER A PERIOD OF TIME AND WILL NOT OCCUR ALL AT ONCE. THE DAM's
DEMOLITION SHALL OCCUR AFTER A PERIOD OF 3 CONSECUTIVE DRY WEATHER DAYS. CONSTRUCTION EQUIPMENT & TRAFFIC D / \ SHALL REMAIN ONSITE AT ALL TIMES AND SHALL ORIGINATE FROM THE PROPOSED RAMBLING BROOK LANE ROAD CROSSING /
UNDER CONSTRUCTION. CONSTRUCTION VEHICULAR TRAFFIC SHALL ONLY TRAVERSE POWELL CREEK AT THIS PLAN's APPROVED /
CROSSING. CONSTRUCTION DEBRIS RESULTING FROM THE DEMOLITION OF THE DAM SHALL BE COLLECTED AND REMOVED FROM /
THE STREAM BUFFER. UPON THE COMPLETION OF THE DAM's DEMOLITION AND REMOVAL, THE CONTRACTOR SHALL STABILIZE
THE CHANNEL BANKS WHERE DISTURBANCES OCCURED IN ACCORDANCE WITH DETAIL 1.1 SHOWN ON THIS SHEET.
