IT IS THE CONTRACTOR'S RESPONSIBILITY TO NOTIFY THE 1-800-ONE-CALL PRIOR TO ANY EXCAVATION. 3. THE CONTRACTOR SHALL CONFIRM THE LOCATION AND DEPTH OF THE EXISTING UTILITY TO WHICH THE CONNECTION IS BEING MADE BEFORE LAYING PIPE, CONDUIT, AND ORDERING PRECAST STRUCTURES, ETC. AS NECESSARY. ANY DISCREPANCY SHALL BE REPORTED TO THE DESIGN ENGINEER. IN CASES WHERE THE CONSTRUCTION OF ITEMS MEET EXISTING STRUCTURES, SUCH AS CURB, PAVEMENT, SIDEWALK, UTILITIES, ETC. THE CONTRACTOR OR SURVEYOR STAKING SUCH ITEMS SHALL VERIFY THE ELEVATION & LOCATION

IN CASES WHERE THE CONSTRUCTION OF ITEMS MEET EXISTING STRUCTURES, SUCH AS CURB, PAVEMENT, SIDEWALK, UTILITIES, ETC. THE CONTRACTOR OR SURVEYOR STAKING SUCH ITEMS SHALL VERIFY THE ELEVATION & LOCATION OF THE EXISTING FEATURE PRIOR TO CONSTRUCTION. ANY AND ALL DISCREPANCIES OR QUESTIONS SHALL BE BROUGHT TO THE ATTENTION OF THE ENGINEER. 4. EXCAVATED SOIL NOT USED FOR RE-GRADING AS SHOWN ON THE PLANS SHALL BE REMOVED AND DISPOSED OF OFF-SITE. 5. ALL AREAS WHERE SOIL IS BEING SPREAD ACROSS THE YARD SHALL BE TOP-SOILED (4-INCH MINIMUM) AND SEEDED IMMEDIATELY FOLLOWING GRADING OPERATIONS. 6.

THE CONTRACTOR AND OWNER SHALL CONTACT MARUCCI ENGINEERING ASSOCIATES, LLC AND/OR THE TOWNSHIP'S ENGINEERING DEPARTMENT WITH THE SOILS RESULTS TO CONFIRM THE DRAINAGE DESIGN AS SHOWN HEREIN. ADJUSTMENTS TO THE DRY WELL DESIGN OR ALTERNATIVE CONNECTIONS TO AVAILABLE TOWNSHIP STORMWATER SYSTEMS MAY BE REQUIRED AS A RESULT OF THE SOIL CONDITIONS. SOIL TEST PIT RESULTS SIGNED & SEALED BY A NEW JERSEY LICENSED PROFESSIONAL ENGINEER MAY BE REQUIRED AND SUBMITTED TO THE TOWNSHIP ENGINEER PRIOR TO COMMENCING CONSTRUCTION OF THE DRY WELL. THE SOIL TESTS SHALL DETERMINE THE DEPTH TO GROUNDWATER AND INCLUDE A CALCULATION TO ILLUSTRATE THE PROPOSED DRY WELL WILL DRAIN WITHIN 72 HOURS. IT IS THE RESPONSIBILITY OF THE OWNER/ CONTRACTOR TO CONTACT THE UNDERSIGNED IMMEDIATELY FOR ANY CONCERNS RELATED TO SOIL CONDITIONS ENCOUNTERED DURING EXCAVATION. GRADING, DRAINAGE, & UTILITY NOTES : 1.
