TREE PROTECTION NOTES
BEFORE WORK BEGINS:
TREE TO MINIMIZE COMPACTION. A TARP OR PLYWOOD BENEATH THE PILE WILL PREVENT CUTTING INTO SOIL SURFACE WITH
BACKHOE OR DOZER BLADE WHEN REFILLING THE TRENCH,
1.
AGREEMENT WILL BE REACHED WITH GENERAL CONTRACTOR, UNC FACILITIES DEPARTMENT, AND UNIVERSITY ARBORIST ON
SPECIFIC TREES THAT WILL BE PRESERVED. COMMUNICATION BETWEEN GENERAL CONTRACTOR, UNC FACILITIES DEPARTMENT,
3.
REFILL OPEN TRENCHES AS SOON AS POSSIBLE. ROOT DEATH CAN OCCUR IN 10 MINUTES IN UNFAVORABLE WEATHER
AND UNIVERSITY ARBORIST IS ESSENTIAL FOR SUCCESS UNTIL PROJECT IS COMPLETED.
CONDITIONS, EXPOSED ROOTS IN OPEN TRENCHES MUST BE KEEP MOIST WITH A HOSE OR SPRINKLER.
2,
CONSIDER AND AGREE UPON SITE ACCESS ROUTES AS THEY RELATE TO DESIGNATED TREES.
4.
RAISING THE GRADE MORE THAN 6" AROUND A TREE TO BE PRESERVED WILL REQUIRE A RETAINING WALL BEYOND THE
EXISTING DRIP LINE.
3.
CONSTRUCTION FENCING WILL BE ERECTED JUST BEYOND THE DRIP LINE OF DESIGNATED TREES AND WILL NOT BE REMOVED
UNTIL COMPLETION OF PROJECT,
S.
IF GRADE MUST BE LOWERED, TERRACING AS FAR FROM THE TREE TRUNK AS POSSIBLE WILL BE REQUIRED TO PRESERVE AS
MANY ROOTS AS POSSIBLE. THIS CAN BE DONE IN STEPS FOR A MORE NATURAL GRADE. WHEN THE GRADE MUST BE LOWERED
4.
WOOD CHIPS AT A DEPTH OF 6-12" SHALL BE USED IN ROOTING ZONE, BEYOND CONSTRUCTION FENCING, WHERE EQUIPMENT
COMPLETELY, CONSTRUCTION OF AN ISLAND ATTHE DRIP LINE WILL BE REQUIRED,

6.
A HEAVY PLASTIC TARP MUST BE SPREAD IN CONCRETE MIXING AREAS AND AREAS WHERE SHEETROCK WILL BE CUT. THE
5.
HEAVY EQUIPMENT WILL BE PARKED AWAY FROM THE ROOT ZONE OF THESE TREES. TEMPORARY "CONSTRUCTION PARKING"
ALKALINITY OF THESE MATERIALS CAN CHANGE SOIL PH.
SIGNS WILL BE ERECTED TO DIRECT OPERATORS. NO SIGNS WILL BE NAILED TO TREES.
7,
PAINT BRUSHES AND TOOLS WILL NOT BE CLEANED OVER TREE ROOTS.
6.
WATER AND UTILITY LINES WILL BE ROUTED AROUND ROOTS OF DESIGNATED TREES WHEN POSSIBLE. TUNNELING WILL BE
MANDATORY WITHIN THE DRIP LINE OF TREES TO BE PRESERVED, TO PREVENT CUTTING OF LARGE ROOTS.

Section 2721
Engineered Surface Drainage Products
GENERAL
PVC surface drainage inlets shall include the drain basin type as indicated on the contract drawing and referenced within the contract specifications. The ductile
iron grates for each of these fittings are to be considered an integral part of the surface drainage inlet and shall be furnished by the same manufacturer. The
surface drainage inlets shall be as manufactured by Nyloplast a division of Advanced Drainage Systems, Inc., or prior approved equal.
MATERIALS
The drain basins required for this contract shall be manufactured from PVC pipe stock, utilizing a thermoforming process to reform the pipe stock to the specified
configuration. The drainage pipe connection stubs shall be manufactured from PVC pipe stock and formed to provide a watertight connection with the specified
pipe system. This joint tightness shall conform to ASTM D3212 for joints for drain and sewer plastic pipe using flexible elastomeric seals. The flexible elastomeric
seals shall conform to ASTM F477. The pipe bell spigot shall be joined to the main body of the drain basin or catch basin. The raw material used to manufacture
the pipe stock that is used to manufacture the main body and pipe stubs of the surface drainage inlets shall conform to ASTM D1784 cell class 12454.
The grates and frames furnished for all surface drainage inlets shall be ductile iron for structure sizes 8", 10", 12", 15", 18", 24", 30" and 36" and shall be made
specifically for each basin so as to provide a round bottom flange that closely matches the diameter of the surface drainage inlet. Grates for drain basins shall be
capable of supporting various wheel loads as specified by Nyloplast. 12" and 15" square grates will be hinged to the frame using pins. Ductile iron used in the
manufacture of the castings shall conform to ASTM A536 grade 70-50-05. Grates and covers shall be provided painted black.
INSTALLATION
The specified PVC surface drainage inlet shall be installed using conventional flexible pipe backfill materials and procedures. The backfill material shall be
crushed stone or other granular material meeting the requirements of class 1, class 2, or class 3 material as defined in ASTM D2321. Bedding and backfill for
surface drainage inlets shall be well placed and compacted uniformly in accordance with ASTM D2321. The drain basin body will be cut at the time of the final
grade. No brick, stone or concrete block will be required to set the grate to the final grade height. For load rated installations, a concrete slab shall be poured
under and around the grate and frame. The concrete slab must be designed taking into consideration local soil conditions, traffic loading, and other applicable
design factors. For other installation considerations such as migration of fines, ground water, and soft foundations refer to ASTM D2321 guidelines.
