CONTRACTOR SHALL VERIFY DEPTHS OF ALL
EXISTING ONSITE UTILITIES PRIOR TO
CONSTRUCTION TO CONFIRM THERE IS NOT
ANY CONFLICTS WITH OTHER UTILITIES, STORM
SEWERS OR STREETS. CONFLICTS AFTER
CONSTRUCTION BEGINS ARE SOLELY THE
CONTRACTOR'S RESPONSIBILITY.
THE STORM SEWER SYSTEM SHALL BE CONSTRUCTED
PER DESIGN SPECIFIED AND AS APPROVED BY THE CITY
OF CARMEL ON THE FINAL APPROVED CONSTRUCTION
PLANS. DEVIATIONS FROM THE APPROVED DESIGN SHALL
ONLY BE PERMITTED DUE TO SPECIAL CIRCUMSTANCES
OR DIFFICULTY DURING CONSTRUCTION AND WILL
REQUIRE PRIOR FIELD APPROVAL FROM A DESIGNATED
REPRESENTATIVE OF THE CITY OR CARMEL IN ADDITION
TO SUPPLEMENTAL APPROVAL BY THE DESIGN
ENGINEER. AN EXPLANATION OF ANY SUCH DEVIATION
SHALL BE INCLUDED AS A REQUIREMENT ON
AS-BUILT/RECORD DRAWINGS SUBMITTED FOR RELEASE
OF PERFORMANCE GUARANTEES. APPROVED DESIGN
SLOPES IDENTIFIED AS GENERATING VELOCITIES OF 2.5
FPS OR LESS AND 10 FPS OR GREATER (AT FULL FLOW
CAPACITY) SHALL REQUIRE AS-BUILT CERTIFICATION AT
THE TIME OF CONSTRUCTION, PRIOR TO BACKFILLING
THE PIPE. THE CONTRACTOR IS INSTRUCTED TO AS-BUILT
EACH SECTION OF STORM PIPE AS IT IS BEING INSTALLED
TO ENSURE COMPLIANCE WITH THE DESIGN PLANS AND
AS APPROVED BY THE CITY OF CARMEL.

BUT UNDER NO CIRCUMSTANCES SHALL THE COVER ALONG
ANY PART OF THE PIPE FROM THE FINAL PAVEMENT
ELEVATION TO THE TOP OF THE PIPE BE LESS THAN 2.5 FEET.
