PROJECT DESCRIPTION
THE PURPOSE OF THIS PROJECT IS FOR THE CONSTRUCTION OF THE NEW TOWN CREEK MIDDLE" SCHOOL AND EXPANSION OF
THE EXISTING TOWN CREEK ELEMENTARY SCHOOL OFF OF LAKE PARK DRIVE SE ON APPROXIMATELY 60.66 ACRES OF WHICH
21.28 ACRES IS THE CURRENT TOWN CREEK ELEMENTARY SCHOOL SITE AND 39.38 ACRES 15 THE CURRENT TOWN CREEK
MIDDLE SCHOOL SITE. THE PROJECT IS TO BE PHASED AS SHOWN ON THE PLANS.
THE PROPOSED 7,607 SF TOWN CREEK ELEMENTARY SCHOOL BUILDING EXPANSION IS TO BE LOCATED ALONG THE SOUTHERN
WING OF THE EXISTING SCHOOL BUILDING. THE EXPANSION CONSISTS OF SIX (6) CLASSROOMS, VESTIBULE, GIRLS RESTROOM
FACILITY, AND BOYS RESTROOM FACILITY.
THE PROPOSED 2-STORY TOWN CREEK MIDDLE SCHOOL BUILDING: ROADWAYS, PARKING LOTS, SIDEWALKS, ATHLETIC FIELDS,
AND ASSOCIATED FACILITIES ARE TO BE LOCATED OFF OF LAKE PARK DRIVE SE NORTHEAST OF THE TOWN CREEK
ELEMENTARY SCHOOL BUILDING WITH SHARED ACCESS ROADWAYS, BUS PARKING, AND WALKWAYS BETWEEN THE SCHOOLS.
THE PROPOSED BUILDING STRADDLES THE EXISTING SCHOOL PROPERTY LINE. THE SHARED PROPERTY LINE SHALL BE
VACATED AND THE PARCELS COMBINED.
159A ACRES WILL BE DISTURBED AS PART OF THIS PROJECT. THE LIMITS OF DISTURBANCE ARE DEFINED ON THE PLANS BY THE
LOCATION OF THE SILT FENCE (SF), TREE PROTECTION (TP), AND/OR CONSTRUCTION FENCE.
ADJACENT PROPERTY
THE PROJECT IS BOUND TO THE NORTH BY A LARGE PARCEL ZONED Cl THAT INCLUDES FORESTED AREA NEAREST THE
PROPOSED PROJECT, AGRICULTURAL AREA, AND A MOBILE HOME OFF OF GOVERNORS ROAD. THE PROJECT IS BOUND TO THE
SOUTH AND EAST BY A LARGE, VACANT PARCEL ZONED R75, PLANS FOR DEVELOPMENT OF THIS VACANT PARCEL WERE
SUBMITTED TO BRUNSWICK COUNTY IN 2007 AND THE STATUS OF THE DEVELOPMENT IS UNKNOWN. THE PROJECT IS BOUND
TO THE WEST BY A LARGE, VACANT PARCEL ZONED R75 AND THE TOWN CREEK PARK ZONED CP.
EXISTING SITE CONDITIONS
THE EXISTING TOWN CREEK ELEMENTARY SCHOOL SITE IS CURRENTLY DEVELOPED AND CONTAINS THE SCHOOL BUILDING,
ASPHALT PARKING LOTS, WALKWAYS, PLAYGROUND STRUCTURES, AND ASSOCIATED FACILITIES. A PORTION OF THE SITE IS
UNDISTURBED WOODLANDS. THE PROJECT AREA CONTAINS GRADUAL TO MODERATE SLOPES. IN GENERAL, THE SITE SLOPES
AWAY FROM THE BUILDING TO THE PERIMETER OF THE PROPERTY.
THE EXISTING TOWN CREEK MIDDLE SCHOOL SITE IS CURRENTLY UNDEVELOPED AND CONTAINS DENSE VEGETATION. THE
PROJECT AREA CONTAINS GRADUAL TO MODERATE SLOPES. IN GENERAL, THE SITE SLOPES TO THE NORTH AND EAST.
THE PROPOSED OFF -SITE AREAS OF WORK FOR THIS PROJECT ARE LOCATED WITHIN THE LAKE PARK DRIVE SE RIGHT OF WAY
AND INCLUDE UTILITY EXTENSIONS AND ROADWAY AND ENTRANCE IMPROVEMENTS.
SOILS
A SOIL BORING REPORT WAS PERFORMED BY ECS SOUTHEAST, LLP DATED DECEMBER 2017 AS PART OF THIS WORK. WHILE
BORING RESULTS VARIED, THE SHWT WAS FOUND APPROXIMATELY 10" - 24" BELOW EXISTING GRADE. AREAS OF SIGNIFICANT
SURFACE WETNESS MAY BE ANTICIPATED THROUGHOUT THE PROJECT AREA DURING CONSTRUCTION. EIGHT SOIL
PERMEABILITY TESTS WERE PERFORMED AND DID NOT SUPPORT THE USE OF INFILTRATION. SEE REPORT FOR DETAILS.
CRITICAL AREAS
THE CRITICAL AREAS OF THIS PROJECT ARE THE 404 WETLANDS & +/-1,200 LF POTENTIAL WATERS OF THE U.S. LOCATED
ALONG THE EASTERN BOUNDARY. APPROXIMATELY 2,169 SF OF WETLANDS 'A' AND 3,546 SF OF WETLANDS 'C' WILL BE
DISTURBED FOR THE INSTALLATION OF THE FIRE LANE AND SIDEWALK AS PART OF THIS WORK. PERMITTING BY THE US ARMY
CORPS OF ENGINEERS BY OTHERS.
EROSION & SEDIMENT CONTROL MEASURES
UNLESS OTHERWISE INDICATED, ALL VEGETATIVE AND STRUCTURAL EROSION & SEDIMENT CONTROL PRACTICES SHALL BE
CONSTRUCTED AND MAINTAINED ACCORDING TO MIN. STANDARDS AND SPECIFICATIONS OF THE NORTH CAROLINA EROSION &
SEDIMENT CONTROL PLANNING AND DESIGN MANUAL. THE CONTRACTOR SHALL SECURE AND MAINTAIN ON SITE A COPY OF
EACH PUBLICATION AND ADHERE TO ALL PRACTICES CONTAINED THEREIN WHICH MAY BE PERTINENT TO THIS PROJECT.
STRUCTURAL PRACTICES
1. TOPSOILING / STOCKPILE - 6.04: TOPSOIL IS TO BE STRIPPED FROM THE AREA OF CONSTRUCTION AND STOCKPILED IN
DESIGNATED AREAS AND STABILIZED AS REQUIRED.
2. TREE PROTECTION - 6.05: TREE PROTECTION FENCE IS TO BE USED TO IDENTIFY AND PROTECT VEGETATION ON SITE
FROM DAMAGE DURING CONSTRUCTION AS SHOWN ON THE PLANS. IT IS ALSO TO PREVENT THE UNNECESSARY REMOVAL
OF VEGETATION DURING CONSTRUCTION. LIMITS OF TREE PROTECTION MAY BE MODIFIED THROUGHOUT CONSTRUCTION
TO ENSURE THE SURVIVAL OF THE VEGETATION DESIGNATED ON THE PLANS.
3. CONSTRUCTION ENTRANCE - 6.06: TEMPORARY CONSTRUCTION ENTRANCES ARE BE INSTALLED AND MAINTAINED
THROUGHOUT CONSTRUCTION. A TEMPORARY CONSTRUCTION ENTRANCE SHALL BE PROVIDED FOR ANY PHASE OR
PORTION OF A PHASE CONNECTING TO A PAVED ROADWAY. ANY AND ALL MATERIAL OR DEBRIS TRACKED ONTO A PUBLIC
OR PRIVATE ROAD WILL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM
ROADS BY SHOVELING OR SWEEPING AND MAY BE TRANSPORTED TO A SEDIMENT CONTROLLED DISPOSAL AREA.
4. TEMPORARY SEEDING - 6.10: ALL DENUDED AREAS LEFT DORMANT FOR EXTENDED PERIODS OF TIME SHALL BE SEEDED
WITH FAST GERMINATING VEGETATION, SELECTION OF THE SEED WILL DEPEND ON THE TIME OF YEAR IT IS APPLIED.
5. PERMANENT SEEDING - 6.11: ALL AREAS NOT OTHERWISE DENUDED ON THE PLAN WITHIN THE LIMITS OF CONSTRUCTION
OR WITHIN STORMWATER CONVEYANCE SYSTEMS LOCATED IN DRAINAGE EASEMENTS RECEIVING RUNOFF FROM
CONSTRUCTION ACTIVITIES ARE TO BE SEEDED WITH APPROVED VEGETATION. SELECTION OF SEED WILL DEPEND ON TIME
OF YEAR IT IS APPLIED.
6. ROLLED EROSION CONTROL PRODUCTS - 6.17'. ROLLED EROSION CONTROL MATS AND BLANKETS ARE INTENDED TO
PROTECT SOIL AND HOLD SEED AND MULCH IN PLACE ON SLOPES AND IN CHANNELS SO THAT THE VEGETATION CAN
BECOME WELL ESTABLISHED. MATTING IS TO BE INSTALLED AS SHOWN ON PLAN.
7. HARDWARE CLOTH AND GRAVEL INLET PROTECTION - 6.51: CLOTH AND GRAVEL INLET PROTECTION WILL BE INSTALLED AS
SHOWN ON PLANS TO PREVENT SEDIMENT FROM ENTERING YARD INLETS, GRATED STORM DRAINS, OR DROP INLETS
DURING CONSTRUCTION. UTILIZING INLET PROTECTION ALLOWS EARLY USE OF THE STORM DRAIN SYSTEM.
8. TEMPORARY SEDIMENT TRAP - 6.60: TEMPORARY SEDIMENT TRAPS) ARE TO BE USED TO DETAIN SEDIMENT -LADEN
RUNOFF AND TRAP THE SEDIMENT TO PROTECT RECEIVING STREAMS; LAKES, DRAINAGE SYSTEMS, AND PROTECT
ADJACENT PROPERTY. SEDIMENT TRAP(S) WILL BE INSTALLED AS SHOWN ON THE PLAN.
9. TEMPORARY SEDIMENT BASIN - 6.61: TEMPORARY SEDIMENT BASIN(S) ARE TO BE USED TO DETAIN SEDIMENT -LADEN
RUNOFF AND TRAP THE SEDIMENT TO PROTECT RECEIVING STREAMS, LAKES, DRAINAGE SYSTEMS, AND PROTECT
ADJACENT PROPERTY. SEDIMENT BASIN(S) WILL BE INSTALLED AS SHOWN ON THE PLAN.
10. SILT FENCE BARRIER - 6.62: SILT FENCE SEDIMENT BARRIERS WILL BE INSTALLED AS SHOWN ON PLAN. UNLESS
OTHERWISE SPECIFIED, THE SILT FENCE WILL ALSO REPRESENT THE LIMITS OF CONSTRUCTION AND DISTURBANCE.
11. WATTLES - 6,66: WATTLES ARE USED TO TRAP SEDIMENT AND OTHER POLLUTANTS IN RUNOFF WATER AS IT PASSES
THROUGH IT. IT ALSO ALLOWS FOR THE DEPOSITION OF SUSPENDED SOLIDS BY TEMPORARILY PONDING THE WATER
BEHIND IT. WATTLES ARE TO BE INSTALLED AS SHOWN ON PLAN.
12. ROCK CHECK DAMS - 6.83: ROCK CHECK DAMS ARE TO BE MAINTAINED AS SHOWN ON THE PLANS TO REDUCE THE
EROSION IN DITCHES AND SWALES FROM CONCENTRATED RUNOFF FLOWS DURING CONSTRUCTION AND TO PREVENT
ACCUMULATION OF SEDIMENT IN EXISTING PIPES AND ENVIRONMENTALLY SENSITIVE AREAS.
MANAGEMENT STRATEGIES
1. LAND DISTURBING ACTIVITIES SHALL BE PLANNED & CONDUCTED TO LIMIT EXPOSURE TO THE SHORTEST FEASIBLE TIME,
2. INSPECT AND REPAIR ALL EROSION CONTROL MEASURES.
3. INSTALL ADDITIONAL EROSION CONTROL MEASURES AS NEEDED THROUGH THE LIFE OF THE PROJECT,
4. STABILIZE ALL DISTURBED AREAS IN ACCORDANCE WITH GENERAL PERMIT NCG 010000,
5, MAINTAIN ALL FACILITIES THROUGHOUT THE CONSTRUCTION OPERATION.
6. UPON ESTABLISHMENT & STABILIZATION OF VEGETATION, REMOVE ALL EROSION CONTROL MEASURES AND STABILIZE.
PERMANENT STABILIZATION
AFTER CONSTRUCTION ALL GRASSED AREAS ARE TO BE PERMANENTLY STABILIZED WITH TOPSOIL AND SEEDING UNLESS
SODDING OR SPRIGGING IS OTHERWISE SPECIFIED, SEEDING IS TO FOLLOW THE GUIDELINES AS FOUND ON THIS PLAN. ANY
CUT AND FILL SLOPES FOUND TO BE EXCESSIVELY ERODING AFTER PERMANENT STABILIZATION SHALL BE PROVIDED WITH
ADDITIONAL STABILIZATION MEASURES UNTIL THE PROBLEM IS CORRECTED. IF ADDITIONAL STABILIZATION MEASURES ARE
REQUIRED; EROSION CONTROL MATTING AND/OR SOD MAY BE USED.
STORMWATER MANAGEMENT
SELECTION OF EROSION & SEDIMENT CONTROL PRACTICES AND STORMWATER CONTROL MEASURES TAKES INTO ACCOUNT
THE EXISTING TOPOGRAPHY AND VEGETATION AS WELL AS THE SOIL BORING REPORT AND INFILTRATION TEST RESULTS.
THE PRIMARY EROSION CONTROL PRACTICES FOR THIS PROJECT ARE SILT FENCE AND TEMPORARY SEDIMENT BASINS/ TRAPS.
A HIGH DENSITY STORMWATER PERMIT, SW8 071210, WAS ISSUED BY THE NCDENR FOR THE TOWN CREEK ELEMENTARY
SCHOOL PROJECT IN 2007 AND MODIFIED ON JUNE 16, 2010. THE STORMWATER RUNOFF FROM THE EXISTING ELEMENTARY
SCHOOL IS CONVEYED BY OPEN CHANNEL AND CLOSED CONVEYANCE SYSTEMS TO AN EXISTING STORMWATER WET POND.
NO NET INCREASE IN IMPERVIOUS AREAS OR STORMWATER RUNOFF TO THE EXISTING STORMWATER WET POND ARE
PROPOSED AS PART OF THIS WORK. THE EXISTING OFF -SITE STORMWATER WET POND WAS DESIGNED AND APPROVED TO
HANDLE 246,395 SF OF IMPERVIOUS AREA WITH NO ADDITIONAL CAPACITY, NO MODIFICATIONS TO THE EXISTING TOWN CREEK
ELEMENTARY SCHOOL STORMWATER WET POND ARE PROPOSED AS PART OF THIS WORK.
ALL STORMWATER RUNOFF FROM THE TOWN CREEK ELEMENTARY SCHOOL EXPANSION AND THE TOWN CREEK MIDDLE
SCHOOL SITE WILL BE DIRECTED TO NEW STORMWATER CONTROL MEASURES (SCM). THE PRIMARY STORMWATER CONTROL
MEASURES FOR THE ELEMENTARY SCHOOL ADDITION ARE A DRY POND LOCATED WITHIIN THE EXISTING OFF -SITE WET POND
DRAINAGE AREA. THE PRIMARY CONTROL MEASURE FOR THE MIDDLE SCHOOL IS A WET POND. SOIL TESTS DID NOT SUPPORT
THE USE OF INFILTRATION.
MAINTENANCE
IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED WEEKLY AND AFTER EACH SIGNIFICANT
RAINFALL. THE FOLLOWING ITEMS WILL BE CHECKED IN PARTICULAR:
1. THE SILT FENCE BARRIER WILL BE CHECKED REGULARLY FOR UNDERMINING OR DETERIORATION OF THE FABRIC.
SEDIMENT SHALL BE REMOVED WHEN THE LEVEL OF SEDIMENT DEPOSITION REACHES 3 HEIGHT TO THE TOP OF THE
BARRIER.
2. CHECK CONSTRUCTION ENTRANCES TO ENSURE STONE AREA IS SUFFICIENT TO REDUCE TRACKING OF MATERIAL OFF
SITE. PAVEMENT SHALL BE KEPT CLEAN DURING CONSTRUCTION OPERATIONS.
3. AREAS OF FINISHED GRADING SUCH AS GRASSED SWALES OR PERMANENTLY GRASSED AREAS ARE TO BE INSPECTED TO
VALIDATE EROSION HAS NOT OCCURRED UP TO THE TIME THAT THE AREAS HAVE BEEN NATURALLY STABILIZED BY THE
USE OF SEEDING. AREAS OF OBSERVED EROSION ARE TO BE RESTORED TO MATCH THE PROPOSED PLAN AND STABILIZED.
4. TEMPORARY SEDIMENT BASINS/TRAPS SHOULD BE CHECKED REGULARLY TO ENSURE THAT THEY ARE STRUCTURALLY
SOUND AND HAVE NOT BEEN DAMAGED BY EROSION OR CONSTRUCTION EQUIPMENT. THEY SHOULD BE CHECKED AFTER
EACH RUNOFF PRODUCING RAINFALL FOR SEDIMENT CLEANOUT, SEDIMENT SHALL BE REMOVED AND PROPERLY
DISPOSED OF.

NOTES:
1. PREPARE SOIL BEFORE INSTALLING ROLLED EROSION CONTROL PRODUCTS (RECP'S), INCLUDING ANY NECESSARY APPLICATION OF LIME, FERTILIZER, AND
SEED.
2. BEGIN AT THE TOP OF THE CHANNEL BY ANCHORING THE RECP'S IN A 12" DEEP X 6" WIDE TRENCH WITH APPROXIMATELY 12" OF RECP'S EXTENDED
BEYOND THE UP —SLOPE PORTION OF THE TRENCH. ANCHOR THE RECP'S WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12" APART IN THE BOTTOM
OF THE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING. APPLY SEED TO COMPACTED SOIL AND FOLD REMAINING 12" PORTION OF
RECP'S BACK OVER SEED AND COMPACTED SOIL. SECURE RECP'S OVER COMPACTED SOIL WITH A ROW OF STAPLES/STAKES SPACED APPROXIMATELY
12" APART ACROSS THE WIDTH OF THE RE-CP'S.
3. ROLL CENTER RECP'S IN DIRECTION OF WATER FLOW IN BOTTOM OF CHANNEL. RECP'S WILL UNROLL WITH APPROXIMATE SIDE AGAINST THE SOIL
SURFACE, ALL RECP'S MUST BE SECUREL.,Y FASTENED TO SOIL SURFACE BY PLACING STAPLES/STAKES PER MANUFACTURER'S RECOMMENDATIONS.
4. PLACE CONSECUTIVE RECP'S END OVER END WITH A 4" — 6" OVERLAP. USE A DOUBLE ROW OF STAPLES STAGGERED 4" "APART AND 4" ON CENTER
TO SECURE RECP'S
5. FULL LENGTH EDGE OF OF RECP'S AT 10,POF SIDE SLOPES MUST BE ANCHORED WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12" APART IN A 6"
DEEP X 6" WIDE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
6. ADJACENT RECP'S MUST BE OVERLAPPED APPROXIMATELY 2" — 5" (DEPENDING ON TYPE) AND STAPLED.
7. IN HIGH FLOW CHANNEL APPLICATIONS, A STAPLE CHECK IS RECOMMENDED AT 30 TO 40 FOOT INTERVALS. USE A DOUBLE ROW OF STAPES
STAGGERED 4" APART AND 4" ON CENTER OVER ENTIRE WIDTH OF CHANNEL.
6. THE TERMINAL END OF THE RECP'S MUST BE ANCHORED WITH A ROW OF STAPLE/STAKES APPROXIMATELY 12" APART IN A 6" DEEP X 6" WIDE TRENCH.
BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
9. IN LOOSE SOIL CONDITIONS, THE USE OF 'TAPLE OR STAKE LENGTHS GREATER THAN 6" MAY BE NECESSARY TO PROPERLY SECURE THE RECP'S.

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 stack 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 Mastic 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 ASTIVI D1784 cell class 12454.
The grates and frames furnished for all surface drainage inlets shall be ductile iron for sizes 8", 10", 12", 15", 18", 24" and 30" 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. gates 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 A535 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 ASTIVi D2321 guidelines.
