1. REFERENCE IS HEREBY MADE TO THE FOLLOWING PLANS FROM WHICH INFORMATION WAS TAKEN: A. "EXISTING CONDITIONS PLAN, BROAD BROOK RESERVOIR DAM, A. "EXISTING CONDITIONS PLAN, BROAD BROOK RESERVOIR DAM, PREPARED FOR TOWN OF EAST WINDSOR, RESERVOIR ROAD, EAST WINDSOR, CONNECTICUT, SCALE: 1" = 10', DATE: NOV. 2013", PREPARED BY J.R. RUSSO AND ASSOCIATES, LLC. 2. NORTH AS SHOWN HEREON IS BASED ON THE ABOVE REFERENCED PLAN. 3. ELEVATIONS SHOWN HEREON ARE BASED ON THE ABOVE REFERENCED PLAN AND ARE BASED ON THE 1988 NORTH AMERICAN VERTICAL DATUM (NAVD 88). 4. THE CONTRACTOR MUST CONTACT CALL-BEFORE-YOU-DIG . THE CONTRACTOR MUST CONTACT CALL-BEFORE-YOU-DIG (1-800-922-4455) FOR UNDERGROUND UTILITY LOCATIONS PRIOR TO ANY EXCAVATION OR CONSTRUCTION AT THIS SITE. IN ADDITION TO POTENTIAL IN ADDITION TO POTENTIAL UNDERGROUND UTILITIES, CAUTION AND PROPER SAFETY MEASURES MUST BE EXERCISED AND INSTITUTED TO AVOID CONTACT WITH OVERHEAD WIRES IN THE DIRECT AND GENERAL VICINITY OF THE WORK. 5. ANY WORK DONE ON THE DAM THAT MAY REQUIRE ACCESS FROM ROUTE 191 (MAIN STREET) MAY ALSO REQUIRE AN ENCROACHMENT PERMIT FROM THE STATE OF CONNECTICUT DEPARTMENT OF TRANSPORTATION. AS NOTED UNDER TRAFFIC CONTROL IN THE CONTRACT DOCUMENTS, SUCH PERMIT WILL BE THE CONTRACTOR'S RESPONSIBILITY.

AutoCAD SHX Text

GENERAL NOTES

AutoCAD SHX Text DEWATERING OPERATIONS ARE THE RESPONSIBILITY OF THE CONTRACTOR AND A DEWATERING PLAN, AS NOTED IN THE SPECIFICATIONS, MUST BE SUBMITTED PRIOR TO BEGINNING CONSTRUCTION. IT IS EXPECTED THAT, IN ORDER TO BEST ACCOMPLISH THE CONSTRUCTION NOTED ON THESE PLANS, A REDUCTION IN NORMAL WATER SURFACE OF A MINIMUM OF 3 FEET WILL BE REQUIRED. SUCH REDUCTION MUST BE APPROVED BY THE DEEP THROUGH THE PERMITTING PROCESS AND OVERSEEN BY THE ENGINEER DURING CONSTRUCTION. THE IMPLEMENTATION PROCEDURE FOR THE DEWATERING OPERATION, INCLUDING CONSTRUCTION OF ANY NECESSARY BYPASS PIPING, OPERATION OF THE EXISTING GATE STRUCTURE AND INSTALLATION OF COFFERDAMS, MUST BE INCLUDED IN THE CONTRACTOR'S SUBMITTAL.
