NOTES:
1. CONTRACTOR SHALL POTHOLE AND VERIFY THE LOCATION, DEPTH, SIZE,
MATERIAL AND CONFIGURATION OF THE EXISTING UTILITIES. VERIFICATION
SHALL BE COMPLETED FAR ENOUGH IN ADVANCE OF THE CONSTRUCTION TO
ADJUST PROPOSED STORM DRAIN SYSTEM TO ACCOMMODATE ACTUAL
CONDITIONS. UNDER NO CIRCUMSTANCES WILL CITY PAY THE CONTRACTOR
ADDITIONAL MONIES TO RELAY STORM DRAIN AND/OR REINSTALL
STRUCTURES AS A RESULT OF THE CONTRACTOR'S FAILURE TO POTHOLE
AND VERIFY EXISTING UTILITIES.
2. THE LOCATION OF EXISTING UTILITIES SHOWN ARE APPROXIMATE. NOT ALL
UNDERGROUND UTILITY DEPTHS ARE KNOWN. THE CONTRACTOR SHALL TAKE
PROPER PRECAUTIONS TO NOT DAMAGE ANY EXISTING UNDERGROUND
UTILITIES. THE CONTRACTOR IS RESPONSIBLE FOR ANY AND ALL DAMAGES
CAUSED DUE TO FAILURE TO LOCATE AND PRESERVE ANY/ALL EXISTING
UTILITIES.
3. SURVEY CONTROL NUMBERS E, SEE DWG G-2.
4. THE MINIMUM REQUIRED CLEARANCE OF CROSSINGS (ABOVE OR BELOW)
BETWEEN THE NEW STORM DRAIN AND EX UTILITIES (WATER, SEWER, GAS,
POWER, PHONE, OR CABLE- MAINS AND SERVICES) IS 12 INCHES FOR UTILITIES
GREATER THAN OR EQUAL TO 6 INCHES IN DIAMETER AND 6 INCHES FOR
UTILITIES LESS THAN 6 INCHES IN DIAMETER. WITH THE ENGINEER'S
APPROVAL, EXCEPTIONS MAY BE ALLOWED PROVIDED THE USE OF
ACCEPTABLE MATERIAL(S) IS USED FOR SEPARATING AND PROTECTING THE
NEW STORM DRAIN AND EXISTING UTILITY. CROSSING CONDITIONS NOT
LISTED SHALL BE APPROVED BY THE ENGINEER, SEE DETAIL 4/C-7.
5. LOCATIONS OF THE SIDE SEWERS SHOWN ARE APPROXIMATE AND MAY NOT
REFLECT ACTUAL LOCATIONS.
6. SEE DRAWING C-1, EXISTING CONDITIONS AND DEMOLITION PLAN, FOR
EXISTING STORM WATER INFRASTRUCTURE REMOVAL AND ABANDONMENT
REQUIREMENTS.
