NATURAL HABITAT BUFFER ZONES
1.THE SIZE, TYPE AND LOCATION OF ALL KNOWN UNDERGROUND UTILITIES ARE
APPROXIMATE WHEN SHOWN ON THESE DRAWINGS. IT SHALL BE THE
RESPONSIBILITY OF THE CONTRACTOR TO VERIFY THE EXISTENCE OF ALL
UNDERGROUND UTILITIES IN THE AREA OF THE WORK. BEFORE COMMENCING NEW
CONSTRUCTION, THE CONTRACTOR SHALL BE RESPONSIBLE FOR LOCATING ALL

3.PIPE LENGTHS ARE CALCULATED FROM THE CENTER OF MANHOLES AND INLET BOX
STRUCTURES. SPECIFIED LENGTH OF PIPE INCLUDES THE LAYING LENGTH OF
FLARED END SECTIONS.
4.WATER SERVICE MUST HAVE MINIMUM OF 4.5' COVER AND MINIMUM OF 18" VERTICAL
CLEARANCE FROM STORM SEWER. ANY STORM SEWER SHALLOWER THAN 5.0' WILL
REQUIRE THE WATER SERVICE TO BE INSTALLED UNDER THE PROPOSED STORM
