From and after the first day of the first full fiscal year of the Corporation, the Annual General Assessment and the Access Street Annual Assessment may be increased upon the vote of a majority of the Board of Directors of the Corporation by no more than ten percent (10%) of the Annual General Assessment or the Access Street Annual Assessment, as the case may be, for the preceding year. p. Any increase of the Annual General Assessment or the Access Street Annual Assessment exceeding ten percent (10%) of the Annual General Assessment or the Access Street Annual Assessment, as the case may be, for the preceding year must be approved by the Owners of at least two-thirds (2/3) of the hots subject to said assessment who are voting in person or by proxy at a special meeting called solely for this purpose. q. Once the Annual General Assessment or Access Street Annual Assessment has been set, notice of the Annual General Assessment and the Access Street Annual Assessment shall be given to all Lot Owners subject to said assessments. It is provided, however, that no Owner is relieved from the obligation to pay the applicable assessment because of failure to give such notice. After the initial notice of the applicable assessment, no bills for such assessment will be forwarded to any Owner but such assessment thereafter shall become due and payable as provided by the Board of Directors. r. The Corporation shall maintain the Access Streets Annual Assessments and the Access Streets Special Assessments in an account separate from all other IC funds of the Corporation. Any other provision of these Restrictions, the Articles and the Bylaws notwithstanding, said Access Street Annual Assessments and Access Street Special Assessments may be expended by the Corporation solely for the purpose of maintenance and repair of the Access Streets. From and after the time, if ever, any Access Street is accepted for public maintenance by the North Carolina Department of Transportation or another governmental entity, said Access Street shall cease to be an Access Street as that term is used in these Restrictions, and the Access Street Lots contiguous to said Access Street shall cease to be Access Street Lots as that term is used in these Restrictions, and thereafter shall not be subject to the Access Street Annual Assessment or Access Street Special Assessment. However, all such Access Street Annual Assessments or Access Street Special Assessments previously paid to the Corporation by the Owners of such Lots shall remain the property of the Corporation for use in maintaining, repairing, replacing and insuring the remaining Access Streets. From and after the time, if ever, the last Access Street is accepted for public maintenance by the North Carolina Department of Transportation or another governmental entity, all Access Street assessment funds of the Corporation, including any past due assessments subsequently collected, shall become general funds of the Corporation available for any proper purpose under these Restrictions, the Articles or the Bylaws. t. The Corporation shall, upon demand, and for a reasonable charge, furnish a certificate signed by an officer of the Corporation setting forth whether the assessments or charges levied against and constituting a lien upon a specified Lot have been paid. A properly executed certificate of the Corporation as to the status of assessments or charges upon on a Lot shall be binding upon the Corporation as of the date of its issuance. U. As provided in the Bylaws, and subject to the restrictions and limitations provided herein, the Board of Directors shall establish an Annual Budget at least sixty (60) days before the beginning of each fiscal year of the Corporation. The Annual Budget shall project all expenses for the forthcoming fiscal year which may be required for the proper 17 operation, management and maintenance of the Corporation, the Common Areas, including the Stormwater Management Facilities located thereon, and the Streets, including a reasonable allowance for contingencies, reserves and the purchase of such casualty and liability insurance as the Board of Directors, in its discretion, deems appropriate. The Annual Budget shall state separately the projection of expenses of the Corporation for the Access Streets. The Annual Budget shall take into account any projected or anticipated income. Upon adoption of the Annual Budget by the Board of Directors and at least thirty (30) days before the beginning of each fiscal year of the Corporation, copies of the Annual Budget shall be delivered to each Owner together with a statement of the assessment or assessments for each Lot as provided herein, based upon such Annual Budget; however, the non -delivery of a copy of the Annual Budget shall not affect the liability of any Owner for such assessment or assessments. The Annual Budget, not including projected expenses for the Access Streets, shall be divided by the number of Lots subject to the Annual General Assessment at the time of the annual meeting of the members and the quotient shall be the Annual General Assessment per Lot for the succeeding fiscal year. The projected expenses for the Access Streets shall be divided by the number of Access Street Lots at the time of the annual meeting of the members and the quotient shall be the Access Street Annual Assessment per Lot for the succeeding fiscal year. V. The failure or delay of the Corporation to prepare or adopt an Annual Budget for any fiscal year shall not constitute a waiver or release in any manner of an Owner's obligation to pay the allocable share of the expenses of the Corporation as herein provided whenever the same shall be determined. In the absence of any Annual Budget, each Owner shall continue to pay assessments at the rate established for the previous fiscal year until notified by the Corporation of the new payment and the due date of said new payment as determined by the Corporation, which due date shall be not less than thirty (30) days after the Owner receives notice of such new Annual Budget. w. All monies collected by the Corporation shall be treated as the separate property of the Corporation and such monies may be applied by the Corporation to the payment of any expense (subject to the restriction on the use of Access Street assessments as provided herein) of operating and managing the Corporation or the proper undertaking of all acts and duties imposed upon it by virtue of this Declaration, the Articles and the Bylaws. As monies for any assessment or other charges are paid into the Corporation by any Owner, the same may be commingled with monies paid to the Corporation by the other Owners (subject to the restriction on the segregation of Access Street assessments from other monies of the Corporation as provided herein). Although all funds and any increments thereto or profits derived therefrom shall be held for the benefit of the members of the Corporation, no member of the Corporation shall have the right to assign, hypothecate, pledge or in any manner transfer said Owner's membership interest therein, except as an appurtenance of said Owner's Lot. When the Owner of a Lot shall cease to be a member of the Corporation by reason of said Owner's divestment of ownership of such Lot, by whatever means, the Corporation shall not be required to account to such Owner for any share of the fund or assets of the Corporation, including any monies which said Owner may have paid to the Corporation, as all monies which any Owner has paid to the Corporation shall be and constitute an asset of the Corporation which may be used in the operation and management of the Corporation. X. Written notice of any meeting called for the purpose of taking any action requiring a meeting of all members or all members who are Access Street Lot Owners shall be sent to all members or all members who are Access Street Lot Owners, as the case may be, not less than thirty (30) days, nor more than sixty (60) days in advance of the meeting. At the first such meeting called, the presence of members or of proxies entitled to cast thirty percent (30%) of the votes of all members or all members who are Access Street Lot Owners, as the case may be, shall constitute a quorum. If the required quorum is not present, another meeting may be called subject to the same notice requirement, and the required quorum at the subsequent meeting shall be one-half (Y2) of the required quorum at the preceding meeting. No such subsequent meeting shall be held more than sixty (60) days following the preceding meeting. 19 y. Any Annual General Assessment, General Special Assessment, Access Street Annual Assessment or Access Street Special Assessment, or other charges assessed against a Lot or the Owner of a Lot pursuant to these Restrictions, if not paid within thirty (30) days after the date such assessment is due, together with interest at the rate of ten percent (10%) per annum, costs of collection, court costs, and reasonable attorneys' fees shall constitute a lien against the Lot upon which such assessment is levied. The Corporation may record notice of the same in the Office of the Clerk of Superior Court of ONSLOW County or file a suit to collect such delinquent assessments and charges. The Corporation may file Notice of Lis Pendens, bring an action at law against the Owner personally obligated to pay the same and/or bring an action to foreclose the lien against the Property. Except as provided below, the sale or transfer of any Lot shall not affect the assessment lien, however, no Owner shall be liable for the payment of any assessment imposed subsequent to the date of recordation of a conveyance by such Owner in fee of such Lot. Prior to or at the time of any such conveyance, all liens, unpaid charges and assessments shall be paid in full and discharged. Any other provision of these Restrictions notwithstanding, the sale or transfer of any Lot pursuant to foreclosure of a first mortgage or any proceeding in lieu therefor, shall extinguish the lien of such assessments and charges as to payments which became due prior to such sale or transfer; provided, however, that if the proceeds of a foreclosure exceed the total amount due to the mortgagee, the excess shall first be paid to the Corporation and applied to the satisfaction of the lien. No sale or transfer shall relieve such Lot from liability for any assessments thereafter becoming due or from the lien thereof. The lien of any assessment provided for herein shall be subordinate to the lien of any first mortgage. 25. Nothing contained herein shall be construed as a dedication to public use of any Common Areas located in the Subdivision and shown on the Map, nor shall it be construed to prevent the Corporation from permitting public access to or use of any such Common Areas. 26. The Declarant, by written and recorded instrument specifically referring to this Declaration may, but is not required to, transfer to the Corporation or to a subsequent owner 20 of property now owned or acquired by Declarant in the Subdivision or adjacent to the Subdivision, any of the rights herein reserved by Declarant. 27. The Declarant or the Corporation with the written consent of the Declarant, may allow reasonable variances and adjustments of these Restrictions in order to overcome practical difficulties and prevent unnecessary hardships in the application of the provisions contained herein; provided, however, that such is done in conformity with the intent and purpose of the general development scheme, that in every instance such variance or adjustment will not be materially detrimental or injurious to other property or improvements in the Subdivision and that in each instance such variance or adjustment complies with the requirements of the Permit. Any such variance shall be recorded in the office of the Register of Deeds of ONSLOW County. 28. The owner of any Lot subject to these Restrictions, by acceptance of a deed conveying title thereto, accepts such deed subject to each and all of these Restrictions and agreements herein contained, and subject to the jurisdiction, rights and powers of the Corporation. The owner of any Lot subject to these Restrictions, by acceptance of a deed conveying title thereto, shall for said owner, said owner's heirs, personal representatives, successors and assigns, covenant, consent and agree to and with the Corporation, the Declarant and the owners and subsequent owners of each of the Lots within the Subdivision, to keep, observe, comply with and perform said Restrictions and agreements. In the case of failure of a Lot owner to comply with the terms and provisions contained in these Restrictions, the Articles or the Bylaws of the Corporation, the following relief shall be available: a. The Declarant (whether or not the Declarant is the owner of any Lot), the Corporation, any Lot owner and any party to whose benefit these Restrictions inure, including, but not limited to the State of North Carolina or its assignees with respect to the provisions of Paragraph 14 hereof, may proceed at law and in equity to prevent the violation of any of these Restrictions, the Articles and Bylaws and also recover damages for such violation and the court in any such action may award the successful parry said party's reasonable expenses and costs in prosecuting such action, including reasonable attorney's fees. 21 b. The remedies hereby specified are cumulative and this specification of them shall not be taken to preclude an aggrieved party's resort to any other remedy at law, in equity or under any statute. No delay or failure on the part of the Corporation, the Declarant or an aggrieved party to invoke an available remedy with respect to a violation of any of these Restrictions, the Articles and Bylaws shall be held to be a waiver by that party of (or an estoppel of that party to assert) any right available to that party upon the reoccurrence or continuation of said violation or the occurrence of a different violation. 29. The owner of any Lot subject to these Restrictions, by acceptance of a deed conveying title thereto, agrees to assume, as against the Corporation and the Declarant, their successors or assigns, all the risks and hazards of ownership or occupancy attendant to such Lot. 30. Declarant shall have the right, but not the obligation, to annex additional property into the Subdivision upon such terms as Declarant, in its sole discretion, determines. From and after the date of such annexation, the annexed property shall be subject to these Restrictions and the jurisdiction of the Corporation and the Owners of Lots located on the annexed property shall be members of the Corporation. 31. Invalidation of any one or more of these covenants by judgment or court order shall not be deemed to affect any of the other provisions which shall remain in full force and effect. IN TESTIMONY WHEREOF, the Declarant has caused this instrument to be executed in such a manner as to be binding. THE NEIGHBORHOODS OF HOLLY RIDGE, LLC (SEAL) By: (SEAL) Scott H.

Cavanaugh has reviewed the RFI and has addressed each item. DWQ's comments are repeated in bold, and the responses and corrections are italicized. 1) Please provide documentation of your status as a member of Neighborhoods of Holly Ridge, LLC. The LLC is a member - managed LLC, therefore, only a member can sign the permit application. The Articles of Incorporation submitted on February 16, 2005, only indicate that you are the initial registered agent. The complete Articles of Incorporation have been included with this response to the RFI. 2) The `sample' of the deed restrictions you provided is not acceptable. Please provide a full copy of the proposed covenants applicable to this subdivision wit the correct permit number and BUA per lot referenced. A permit cannot be issued until correct deed restrictions are provided. The complete convents have been included with this response to the RFI. The correct permit # and BUA per lot are referenced. 3) The use of .05 vs. .07 as a factor in the calculation of required surface area is based on the use of a vertical sand filter. Per Section 4.3 of the BMP Manual, the vertical sand filter is not encouraged for use in NC because it allows for the potential short-circuiting of the bio-retention basin. Please remove the vertical sand filter from the basin details and use .07 to determine o the minimum surface area. All minimum areas are provided, even � with the use of .07. ' `IZ The design of each bioretention area has been modified to not incorporate the use of a sand filter. Subsequently, the minimum areas �w for the bioretention areas have been recalculated using a factor of 0.07 �.; instead of 0.05. All changes have been updated in the plan set as well. Gf� Please see the attachment for details. Stormwater Application No. SW8 050213 1 of 2 2/25/2005 4) The design storm has been reduced to 1.5", and the required 50' vegetated filters need to be labeled and detailed on the plans. A vegetated filter is NOT a swale or ditch. It is a horizontally flat, preferably on natural contour, grassed area with a flow spreader mechanism to promote sheet flow across the width of the filter. The volume for each bioretention area has been modified to treat the first 2" of rainfall, thus eliminating the need for a vegetated filter. All changes in ponding depth and pond volume have been incorporated in the plans. Please see attachment for details. . 5) For the bypass line leaving BA #2, please delete the catch basins and provide manholes. Runoff from the lots may not directly enter the bypass lines. Catchbasins # 1 and #2 have been modified to be junction boxes with solid standard manhole lids marked 'storm sewer,' and have been updated in the plans. 6) Please add a note to the rock bypass weir for BA #1 to reference the clay keyway detail. A note referencing the clay keyway detail has been attached to the rock bypass weir for bioretention area # 1. Thank you, Eaward 'I ed° Burke, E.I.

Front Street, Suite 202, Wilmington, North Carolina 28401, Phone 910/392-4462, Fax 910/392-4612 Narrative Site Description The site, located in the Town of Holly Ridge approximately 1.4 miles south along NC Highway 50 from the intersection of US Highway 17 and NC Highway 50, will serve as the location for the Neighborhoods of Holly Ridge development. Phase I of this development is a 12.2-acre parcel of undeveloped land. The topography of the land in Phase I can be generally described as having a crown in the middle, with either side draining to the north and south ends of the property respectively,- thus creating two natural drainage basins. This middle crown has an approximate elevation of 30.0-ft MSL. Currently, the runoff to the south of this crown drains to the south end of the property (approximate elevation of 27.0-ft MSL) which is bordered by a natural wetland area. All wetlands on site have been delineated and were reviewed by the USACE on September 28th, 2004. The runoff to the north of this crown drains to the north end of the property (approximate elevation of 27.0-ft MSL) which is bordered by an unnamed tributary of County -Line Branch. County -Line Branch has a water classification of SA:HQ waters. The site however, is located less than a'/2 mile from these waters. * Currently, there have been no onsite improvements. Therefore the relative impervious area is zero percent. *see attached location map Project Description This Stormwater Management Plan accounts for Phase One of the proposed development of the site. The proposed development, consisting primarily of two asphalt roadways, sidewalk, and 48 houses and driveways, would increase the impervious area from 0% to approximately 37%.* Lots will be deeded with restrictive covenants for 2,800 sq.ft. per lot. Stormwater runoff generated by the proposed development will be treated utilizing four (4) bioretention areas. To effectively handle this quantity of runoff, we divided the site into 4 separate drainage areas. Stormwater will be collected via sheet flow from each respective drainage area into curbing and, from curb inlets, conveyed through HDPE DR32.5 (51 psi) pipe to the appropriate bioretention area. * TOTAL IMPERIVOUS AREAS Asphalt Roadway: 1.23 acres Sidewalk: 0.17 acres Houses, driveways: 3.10 acres (2,800 sq.ft. per lot) Calculation 1.23 + 0.17 + 3. 10 = 4.5 acres 4.5 acres (impervious)/12.5 (total) = 0.37 4 37% The Neighborhoods of Holly Ridge: Phase l Stormwater Management High Density Permit Application Stormwater Management Plan Collection The lots will be graded in such a manner that the new impervious areas will drain towards the street. The stormwater to be treated will be collected via sheet flow into curb along each side of the roadway surface. This water will be collected through 11 curb inlets and one curb cut. Conveyance Stormwater from the impervious areas will be conveyed to the respective bioretention areas through 1,567 linear feet of HDPE DR32.5 (51 psi) pipe. The diameter and lengths of pipe are listed as follows: 14": 590 LF 18": 300 LF 24": 370 LF 30": 307 LF Treatment Since our project site is located in a coastal county, and lies within one half mile of SA:HQ waters, the method of treatment must utilize infiltration. After discussions with North Carolina Department of Environment and Natural Resources, Division of Water Quality's staff, it was determined the best option for stormwater treatment for this project is bioretention areas. Bioretention Areas For Phase I of this project, four (4) Bioretention Areas were designed in accordance with NCDENR's Stormwater Management Best Management Practices manual, to treat the proiect drainage areas' runoff. The manual requires the treatment of the volume of water generated by the "first flush" of a 10-year storm event. This volume is calculated by multiplying the net impervious surface area times a depth of 2"(typical). Phase One's impervious areas include the roadway, grass, side walks, and all impervious area on each lot. Restrictive covenants set forth by the developer set each lot's net impervious area at a maximum of 2,800 sq.ft..* This area is to include the house, driveway, and any other impervious surfaces on each lot. *see attached restrictive covenants Upon collection and conveyance of this runoff, the stormwater is directed across a rip -rap apron and discharged into a root zone area. Each of these components was sized according to the respective volume of water they will encounter. Also, as required by DENR regulations, each system was designed to function as an "off line system". This means that all stormwater up to the 2" storm event is The Neighborhoods of Holly Ridge: Phase I Stormwater Management High Density Permit Application collected and treated in the bioretention area, however for greater volumes an elevation controlled bypass allows additional water to be carried away without overflowing the system. In order to model the properties of a terrestrial forest community ecosystem, each area was designed to incorporate approved plants according to a planting schedule laid out in DENR BMP. The plant species were selected based on their ability to tolerate urban stresses such as pollutants, variable soil moisture and ponding fluctuations. Plant placement was made in such a manner to appear natural. Plants were not placed in the immediate areas where water flow will be entering. Also, trees were planted primarily on the perimeter of the bioretention area to maximize shading. The following list describes more specific sizing details and elevations for each Bioretention Area. Bioretention Area # 1: Located at the south end of the project, this area was designed to treat runoff from Drainage Basin #1 (54,777 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 2" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 6,399 c.f. of stormwater. Soil borings taken in the vicinity of this location determined the water table elevation to be approximately 23.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 25.00' MSL and the maximum ponding elevation at 25.99' MSL. This area was designed with a planting schedule that includes 98 shrubs and 39 trees. Bioretention Area # 2: Also located at the south end of the project and on the west side of Belvedere Drive, this area was designed to treat runoff from Drainage Basin #2 (24,191 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 2" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 3,112 c.f. of stormwater. Soil borings taken in the vicinity of this location determined the water table elevation to be approximately 24.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 26.00' MSL and the maximum ponding elevation at 26.99' MSL. This area was designed with a planting schedule that includes 45 shrubs and 18 trees. Bioretention Area # 3: Located approximately halfway down Belvedere Drive, on the west side, this area was designed to treat runoff from Drainage Basin #3 (17,144 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 2" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 2,011 c.f. of stormwater. Soil borings taken in the. vicinity of The Neighborhoods of Holly Ridge: Phase I Stormwater Management High Density Permit Application this location determined the water table elevation to be approximately 25.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 27.00' MSL and the maximum ponding elevation at 28.00' MSL. This area was designed with a planting schedule that includes 28 shrubs and 11 trees. Bioretention Area # 4: Located adjacent to Azalea Drive, at the north end of the project, this area was designed to treat runoff from Drainage Basin #4 (205,710 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 2" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 20,189 c.f. of stormwater. Soil borings taken in the vicinity of this location determined the water table elevation to be approximately 20.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 22.00' MSL-and the maximum ponding elevation at 22.98' MSL. This area was designed with a planting schedule that includes 331 shrubs and 133 trees. This site posed some interesting challenges in regard to water table depths. The BMP design criteria for Bioretention areas require that there be two feet of separation from the bottom of the system and the existing water table. Independent soils testing revealed that the true water table depths in the vicinity of the proposed bioretention areas for the site were between 42"-54". (see attached soils data). Mr. Vincent Lewis of NCDENR visited the site to perform hand auger bores to estimate what he believed to be the water table depths. (see attached DENR site sketch) Mr. Lewis determined the water table depths to range from 40"-43" with the exception of the location for Bioretention area #4, located at the north end of the project. Saturated soils were being encountered at 24" below grade therefore that is where Mr. Lewis designated the water table as being. He further explained, however, that this was due to a perching effect and that poorly draining clay material was believed to be the cause. To be prudent, representatives from the independent testing firm, Cavanaugh & Associates, and Mr. Lewis all met for a second site visit to reevaluate the situation. It was agreed by all parties that the natural water table was 6'-7' below existing grade. This is supported by the fact that there is an adjacent creek and wetland at an elevation of approximately 7 feet lower than existing grade. In addition to this, a pre-existing sediment trap that had been constructed only a few feet away had very little water in the bottom. After further discussion with officials from NCDENR, it was agreed that in the areas where a perched water table was an issue, excavation of these poorly draining soils down to the true water table depth and backfilling with appropriately draining material would satisfactorily eliminate the perching effect of the existing soils. The Neighborhoods of Holly Ridge: Phase I Stormwater Management High Density Permit Application Discharge/Bypass Each of these bioretention areas were designed to have a bypass system that will re-route rainfall above the 2" storm event, including the 100-year storm event. Three of the four (4) bioretention areas' (BA#1,#2,#3) bypasses will discharge into a 50' vegetated swale that ultimately terminates in the adjacent wetlands. These swales will add additional treatment of the stormwater. The bypass system for bioretention area #4 will not utilize a vegetated swale and will be discharged via drainage pipe over a rip rap apron and terminate in an adjacent tributary to County Line Branch. Maintenance and Monitoring A maintenance plan*, as listed below, was.developed to maintain proper functionality and longevity for each Bioretention Area. In addition to this, 6" PVC monitoring wells will be placed adjacent to each Bioretention Area to allow water table elevations to be monitored. Maintenance Plan The plant material will be watered every day for fourteen consecutive days, and after planting has been completed. As Needed: 1. Treat all diseased trees, shrubs and vegetation. 2. Replace deficient, defective or rotted support stakes. Monthly: 1. Inspect and repair any eroded areas. 2. Remulch any void areas. 3. Inspect and repair any eroded areas. 4. Remulch any void areas. Twice a Year: 1. Remove and replace dead and/or untreatable diseased vegetation. 2. Replace support stakes as needed in the spring. Yearly- 1. Apply a new layer of mulch in the spring.

Director Division of Water Quality February 18, 2005 Mr. Scott Cook Neighborhoods of Holly Ridge, LLC 429 Long Leaf Drive Hampstead, NC 28443 Subject: Request for Additional Information Stormwater Project No. SW8 050213 Neighborhoods of Holly Ridge Onslow County Dear Mr. Cook: The Wilmington Regional Office received a Stormwater Management Permit Application for Neighborhoods of Holly Ridge on February 16, 1005. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Please provide documentation of your status as a member of Neighborhoods of Holly Ridge, LLC. The LLC is a member -managed LLC, therefore, only a member can sign the permit application. The Articles of Incorporation submitted on February 16, 2005, only indicate that you are the initial registered agent. 2. The "sample" of the deed restrictions you provided is not acceptable. Please provide a full copy of the proposed covenants applicable to this subdivision with the correct permit number and BUA per lot referenced. A permit cannot be issued until correct deed restrictions are provided. 3. The use of .05 vs. .07 as a factor in the calculation of required surface area is based on the use of a vertical sand filter. Per Section 4.3 of the BMP Manual, the vertical sand filter is not encouraged for use in NC because it allows for the potential short-circuiting of the bio-retention basin. Please remove the vertical sand filter from the basin details and use .07 to determine the minimum surface area. All minimum areas are provided, even with the use of .07. 4. The design storm has been reduced to 1.5", and the required 50' vegetated filters need to be labeled and detailed on the plans. A vegetated filter is NOT a swale or ditch. It is a horizontally flat, preferably on natural contour, grassed area with a---� flow spreader mechanism to promote sheet flow across the width of the filter. 5. For the bypass line leaving BA #2, please delete the catch basins and provide manholes. Runoff from the lots may not directly enter the bypass lines. 6. Please add a note to the rock bypass weir for BA #1 to reference the clay keyway detail.

All calculation data is respective to bioretention area 1. The drainage basin for each bioretention area was broken up into its type of surface, total area, its corresponding "C" value, and "C" x Area (weighted Area). The main types were roadway (C=0.90), Sidewalk (C=0.90), Lot Impervious (C=0.90), and Grass (C=0.25). This was modeled from page 39 of the Stormwater Best Management Practices, April 1999 Edition. Bioretention Area 1 Development Area C C x Area [name] [sq ft] [factor] [sq ft] Roadway 8,816 0.90 7,934 Lot Impervious 30,800 0.90 27,720 Grass 15,161 0.25 3,790 Totals 54,777 --- 39,445 The bioretention areas were designed to use a sand bed so the formula on page 39 indicates that the minimum bioretention area size is 5% of the sum of C x Area for each bioretention area: BA = 0.05 * E(C x A) For bioretention area 1, the minimum area is: BA Minimum Area = ( 0.05 ) * ( 39,445sf ) = 1,972 square feet The area designed in bioretention area 1 is 4,380 square feet which gives a design factor of 2.20 ( 4,380sf / 1,972sf ). The minimum design volume for each bioretention area was calculated from the Scheuler Simple method. It states that the volume to retain is a product of the design rainfall (P), the drainage area (Ad), and the runoff coefficient (Rv). Rv is the summation of 0.009 times the percent impervious ( I ) and 0.05. Rv = 0.05 + 0.009 * (1) I = 100 * (8,816 + 30,800) / 54,777 = 72.3% Impervious Rv=0.05+0.009*(72.3%) =0.701 V=(P)*(Rv)*(Ad) V = (1.50in ) * ( 0.701 ) * ( 54,777sf) * ( 1 ft / 12in) = 4,799cf The volume designed in this bioretention area was determined from the trapezoidal method of contour volumes. The contours areas for the bottom elevation and the 1' volume were 4,380sf and 5,219sf respectively. This gave a volume within that 1' contour to be: Volume in 1 foot = ( 1ft ) * (4,380sf + 5,219sf ) / 2 = 4,800cf The volume designed in bioretention area 1 is 4,800cf, which gives a design factor of 1.00 ( 4,800cf / 4,799cf )-. In addition to the design volume described above, one foot of free board was added to bioretention area 1. The ponding elevation of the first 1.50 inches of rainfall was determined from a simple mass balance in the bioretention area. It was assumed that the bioretention area is to experience an instantaneous volume of 4,799 cubic feet of stormwater. The losses to the system are infiltration in the root zone, infiltration in the sand filter, and evapotranspiration from the flora. Evapotranspiration data was gathered from page 43 of the Stormwater Best Management Practices Manual. The depth was algebraically determined assuming a linear average volume increment for the first foot of storage in the bioretention area. For bioretention area 1, 1he volume flow, 4,799cf, corresponds to a depth of 1.0ft, the maximum allowable depth as per DENR, DWQ, Wilmington Regional Office. Infiltration rates of 2.41 in/hr and 8.27in/hr (pg 43 BMP Manual) were used for the root zone and sand filter respectively. The volume per hour infiltration rate was determined from the product of the area of each zone multiplied by the infiltration rate. This gave loss rates of 68.9cf/hr for the sand filter and 880cf/hr for the root zone. Evapotranspiration rates from April to October for Alfalfa, the reference crop, were obtained from page 43 of the BMP Manual. The manual indicated that bioretention area flora will have evapotranspiration rates that are 85% of the rate for Alfalfa. The lowest evapotranspiration rate (October, 2.24in/mo) was used for the design of the bioretention areas. The evapotranspiration rates were then converted to volume rates by multiplying the evapotranspiration rate by the surface area of the bioretention area root zone. This calculated vale for bioretention area 1 was determined to be 1.10cf/hr. Additions = 4,799cf Losses = 68.9cf + 880cf + 1.10cf = 950cf Volume after 1 hour = 4,799 - 950cf = 3,849cf The depth associated with a volume of 3,849cf was determined in the same manner that the initial depth was determined. This gave the depth in the bioretention area after 1 hour. The process was continued until the volume in the bioretention area = 0, in which the total drawdown time was determined to be 6 hours.

Front Street, Suite 202, Wilmington, North Carolina 26401, Phone 910/392-4462, Fax 910/392-4612 Narrative Site Description The site, located in the Town of Holly Ridge approximately 1.4 miles south along NC Highway 50 from the intersection of US Highway 17 and NC Highway 50, will serve as the location for the Neighborhoods of Holly Ridge development. Phase I of this development is a 12.2-acre parcel of undeveloped land. The topography of the land in Phase I can be generally described as having a crown in the middle, with either side draining to the north and south ends of the property respectively, thus creating two natural drainage basins. This middle crown has an approximate elevation of 30.0-ft MSL. Currently, the runoff to the south of this crown drains to the south end of the property (approximate elevation of 27.0-ft MSL) which is bordered by a natural wetland area. All wetlands on site have been delineated and were reviewed by the USACE on September 28th, 2004. The runoff to the north of this crown drains to the north end of the property (approximate elevation of 27.0-ft MSL) which is bordered by an unnamed tributary of County -Line Branch. County -Line Branch has a water classification of SA:HQ waters. The site however, is located less than a'/2 mile from these waters. * . Currently, there have been no onsite improvements. Therefore the relative impervious area is zero percent. *see attached location map Project Description This Stormwater Management Plan accounts for Phase One of the proposed development of the site. The proposed development, consisting primarily of two asphalt roadways, sidewalk, and 48 houses and driveways, would increase the impervious area from 0% to approximately 37%.* Lots will be deeded with restrictive covenants for 2,800 sq.ft. per lot. Stormwater runoff generated by the proposed development will be treated utilizing four (4) bioretention areas. To effectively handle this quantity of runoff, we divided the site into 4 separate drainage areas. Stormwater will be collected via sheet flow from each respective drainage area into curbing and, from curb inlets, conveyed through HDPE DR32.5 (51 psi) pipe to the appropriate bioretention area. * TOTAL IMPERIVOUS AREAS Asphalt Roadway: 1.23 acres Sidewalk: 0.17 acres Houses, driveways: 3.10 acres (2,800 sq.ft. per lot) Calculation 1.23 +0.17+3.10=4.5 acres 4.5 acres (impervious)/12.5 (total) = 0.37 -i 37% The Neighborhoods of Holly Ridge: Phase l Stormwater Management High Density Permit Application r Stormwater Management Plan Collection The lots will be graded in such a manner that the new impervious areas will drain towards the street. The stormwater to be treated will be collected via sheet flow into curb along each side of the roadway surface. This water will be collected through 11 curb inlets and one curb cut. Conveyance Stormwater from the impervious areas will be conveyed to the respective bioretention areas through 1,470 linear feet of HDPE DR32.5 (51 psi) pipe. The diameter and lengths of pipe are listed as follows: 14" : 636 LF 18" : 300 LF 24" : 370 LF 30" : 164 LF Treatment Since our project site is located in a coastal county, and lies within one half mile of SA:HQ waters, the method of treatment must utilize infiltration. After discussions with North Carolina Department of Environment and Natural Resources, Division of Water Quality's staff, it was determined the best option for stormwater treatment for this project is bioretention areas. Bioretention Areas For Phase I 'of this project, four (4) Bioretention Areas were designed in accordance with NCDENR's Stormwater Management Best Management Practices manual, to treat the project drainage areas' runoff. The manual requires the treatment of the volume of water generated by the "first flush" of a 10-year storm event. This volume is calculated by multiplying the net impervious surface area times a depth of 1.5". Phase One's impervious areas include the roadway, grass, side walks, and all impervious area on each lot. Restrictive covenants set forth by the developer set each lot's net impervious area at a maximum of 2,800 sq.ft..* This area is to include the house, driveway, and any other impervious surfaces on each lot. *see attached restrictive covenants Upon collection and conveyance of this runoff, the stormwater is directed across a rip -rap apron, followed by a sand filter strip, and finally discharged into a root zone area. Each of these components was sized according to the respective volume of water they will encounter. Also, as required by DENR regulations, each system was designed to function as an "off line system". This means that The Neighborhoods of Holly Ridge: Phase 1 Stormwater Management High Density Permit Application all stormwater up to the 1.5" storm event is collected and treated in the bioretention area, however for greater volumes an elevation controlled bypass allows additional water to be carried away with out overflowing the system. In order to model the properties of a terrestrial forest community ecosystem, each area was designed to incorporate approved plants according to a planting schedule laid out in DENR BMP. The plant species were selected based on their ability to tolerate urban stresses such as pollutants, variable soil moisture and ponding fluctuations. Plant placement was made in such a manner to appear natural. Plants were not placed in the immediate areas where water flow will be entering. Also, trees were planted primarily on the perimeter of the bioretention area to maximize shading. The following list describes more specific sizing details and elevations for each Bioretention Area. Bioretention Area # 1: Located at the south end of the project, this area was designed to treat runoff from Drainage Basin #1 (54,777 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 1.5" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 4,799 c.f. of stormwater. Soil borings taken in the vicinity of this location determined the water table elevation to be approximately 23.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 25.00' MSL and the maximum ponding elevation at 26.00' MSL. This area was designed with a planting schedule that includes 72 shrubs and 29 trees. Bioretention Area # 2: Also located at the south end of the project and on the west side of Belvedere Drive, this area was designed to treat runoff from Drainage Basin #2 (24,191 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 1.5" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 2,334 c.f. of stormwater. Soil borings taken in the vicinity of this location determined the water table elevation to be approximately 24.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 26.00' MSL and the maximum ponding elevation at 26.83' MSL. This area was designed with a planting schedule that includes 40 shrubs and 15 trees. Bioretention Area # 3: Located approximately halfway down Belvedere Drive, on the west side, this area was designed to treat runoff from Drainage Basin #3 (17,144 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 1.5" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 1,508 c.f. of stormwater. Soil borings taken in the vicinity of The Neighborhoods of Holly Ridge: Phase I Stormwater Management High Density Permit Application this location determined the water table elevation to be approximately 25.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 27.00' MSL and the maximum ponding elevation at 27.91' MSL. This area was designed with a planting schedule that includes 17 shrubs and 7 trees. Bioretention Area # 4: Located adjacent to Azalea Drive, at the north end of the project, this area was designed to treat runoff from Drainage Basin #4 (205,710 sq.ft.). In accordance with the BMP manual, this bioretention area was sized to treat and store the first 1.5" of runoff. Utilizing the Scheuler Method, this equates to a treatment volume of 15,538 c.f. of stormwater. Soil .borings taken in the vicinity of this location determined the water table elevation to be approximately 20.00' MSL. From this elevation, the bottom of the bioretention area was set at an elevation of 22.00' MSL and the maximum ponding elevation at 23.00' MSL. This area was designed with a planting schedule that includes 240 shrubs and 96 trees. This site posed some interesting challenges in regard to water table depths. The BMP design criteria for Bioretention areas require that there be two feet of separation from the bottom of the system and the existing water table. Independent soils testing revealed that the true water table depths in the vicinity of the proposed bioretention areas for the site were between 42"-54". (see attached soils data). Mr. Vincent Lewis of NCDENR visited the site to perform hand auger bores to estimate what he believed to be the water table depths.(see attached DENR site sketch) Mr. Lewis determined the water table depths to range from 40"-43" with the exception of the location for Bioretention area #4, located at the north end of the project. Saturated soils were being encountered at 24" below grade therefore that is where Mr. Lewis designated the water table as being. He further explained, however,. that this was due to a perching effect and that poorly draining clay material was believed to be the cause. To be prudent, representatives from the independent testing firm, Cavanaugh & Associates, and Mr. Lewis all met for a second site visit to reevaluate the situation. It was agreed by all parties that the natural water table was 6'-7' below existing grade. This is supported by the fact that there is an adjacent creek and wetland at an elevation of approximately 7 feet lower than existing grade. In addition tothis, a pre-existing sediment trap that had been constructed only a few feet away had very little water in the bottom. After further discussion with officials from NCDENR, it was agreed that in the areas where a perched water table was an issue, excavation of these poorly draining soils ,down to the true water table depth and backfilling with appropriately draining -material would satisfactorily eliminate the perching effect of the existing soils. The Neighborhoods of Holly Ridge: Phase I Stormwater Management High Density Permit Application Discharge/Bypass Each of these bioretention areas were designed to have a bypass system that will re-route rainfall above the 1.5" storm event, including the 100-year storm event. As required by the BMP manual, each of the four (4) bioretentior. areas' (BA#1,#2,#3,#4) bypasses will discharge into a 50' vegetated swale that ultimately terminates in the adjacent wetlands. This swale adds additional treatment to the stormwater. Maintenance and Monitoring A maintenance plan*, as listed below, was developed to maintain proper functionality and longevity for each Bioretention Area. In addition to this, 6" PVC monitoring wells will be placed adjacent to each Bioretention Area to allow water table elevations to be monitored. Maintenance Plan The plant material will be watered every day for fourteen consecutive days, and after planting has been completed. As Needed: i . Treat all diseased trees, shrubs and vegetation. 2.

Neighborhoods of Holly Ridge Holly Ridge, North Carolina Dear Mr. Cook: October 22, 200A ECS, Ltd. Project No. i 1081 Engineering Consulting Services, Ltd. (ECS) recently conducted an infiltration evaluation for the proposed commercial site located near the intersection of NC Hwy 17-and NC Hwy 50 in Holly Ridge, North Carolina This letter, with attachments, is the report of our investigation. Field Investigations On October 20, 2004, ECS conducted an investigation of the subsurface soil and ground water conditions at the approximate locations indicated on the provided Site Sketch. The purpose of our investigation was to determine the subsurface soils and the infiltration rate of the subsurface soils. We investigated the subsurface soil and ground water conditions by drilling seven hand auger boring to a depth of approximately five to seven feet below the existing ground surface at the approximate locations indicated on the site sketch. The test locations were selected by Mr. Jeff Holland of Cavanaugh and Associates. We visually classified the subsurface soils: The attached Infiltration Evaluation Form provides a summary of the subsurface conditions encountered at the hand auger boring locations and the result of our infiltration tests. Our field classifications indicate that the subsurface soils at the test locations consisted of silty fine to medium sands, fine to medium Sands, and. clay strata,. Ground water was encountered depths ranging from 6 to 60'inches below present site grade. We conducted five infiltration tests near hand auger boring locations #1, #2, #3, #6 and #7. Infiltration tests were not conducted at locations #4 and #5 due to shallow groundwater.

Infiltration test #2 was performed at a depth of approximately 24 inches below existing grade and indicated an infiltration rate of 0.075 inches per minute (4.5 in/hr). Infiltration test #3 was performed at a depth of approximately 24 inches below existing grade and indicated an infiltration rate of 0.225 inches per minute (13.5 in/hr). Infiltration test #6 was performed at a depth of approximately 24 inches below existing ,grade and indicated an infiltration rate of 0.05 inches per minute (3 in/hr). Infiltration test #7 was performed at a depth of approximately-6 inches below existing grade and indicated an infiltration rate of 0.025 inches per minute (1.5 in/hr). Please see the attached site sketch for the infiltration test location. Evaluations Based on observations in the hand auger borings, it is our opinion that the seasonal high ground water level at the infiltration test locations ranges from a depth of approximately 30 inches to 54 inches below existing grade. The lower stratum of relatively free -draining fine to medium sands is expected to have infiltration rates considerably greater than the controlling infiltration rates for the shallow soils. It is also likely that the seasonal high groundwater conditions and infiltration rates can vary across the site due to naturally occurring soil type and because of the surface topography.

Highway 50 in the Town of Holly Ridge, about one and a half mile south of the intersection of N.C_ Highway 50 and U.S. Highway 17. The Neighborhoods of Holly Ridge Phase 1 Construction incorporates the full development of approximately 13 acres of heavily wooded virgin land that has wetlands bordering on 3 full sides. The 13 acre site will be rough graded according to the Erosion and Sedimentation Control Plan, yielding approximately 5,000 cubic feet of soil to be removed from the site. Forty eight lots with water, sewer, electric, and cable utilities are planned for phase one construction. A pump station is also needed to pump the sewage from the project site approximately 4,600 linear feet to an existing manhole at Borrough's Lane. The water will also be acquired from tapping into an existing waterline along Borrough's Lane. Stormwater will be collected in catch basins along the road and delivered to 4 stormwater bioretention areas located at opposite ends of the site. Approximately 1,600 linear feet of roadway for Belvedere Drive and approximately 350 linear feet of roadway Azalea Drive, the entrance, will be constructed as well. A turn lane built to N.C.D.O.T. standards will be required off of N.C. Highway 50 to enter the site. 1. PROJECT DETAILS: A.

SCOPE. This section covers field hydrostatic pressure and leakage testing and disinfection of the pipelines set forth herein. 2. GENERAL. Unless otherwise specified, testing of pipelines shall be completed prior to final cleaning and disinfection. The Engineer shall be present during- the performances of all testing work and shall be notified of the time and place of testing at least 3 days prior to commencement of the work. All work shall be performed to the satisfaction of the Engineer. A. Water. Water shall be conserved through collection and reuse in subsequent testing work. Following completion of testing work, the water shall be disposed of in a manner acceptable to the Engineer. Unless otherwise permitted, the water shall not be allowed to enter other parts of the pipeline system. B. Filling and Venting. When filling the line with water, care shall be taken to ensure that all air valves and other venting devices are properly installed and in the open position. Hand -operated vent valves shall not be closed until water flows in an uninterrupted stream from each valve. Care shall be taken to ensure that the rate at which the line is filled with water does not exceed the venting capacity of the system. C. Blocking and Backfilling. Piping shall be adequately blocked, anchored, and supported before the test pressure is applied. D. Test Equipment. All necessary piping connections between the line to be tested and the water source, together with pumping equipment, water meter, pressure gauges, and all other equipment, materials, and facilities required to perform the specified tests, shall be provided. All flanges, valves, bulkheads, bracing, blocking, and other sectionalizing devices required shall also be provided. All temporary -sectionalizing devices shall be removed upon completion of testing.

Testing pressures shall be applied by means of a force pump sized to provide and maintain the required pressure without interruption during the testing. Water meters and pressure gauges shall be accurately calibrated and shall be subject to review and acceptance by the Engineer. 3. PRESSURE AND LEAKAGE TESTING. After the line to be tested has been filled with water, the test pressure shall be applied and maintained without interruption for 2 hours plus any additional time required for the Engineer to examine all piping undergoing the test and for the Contractor to locate all defective joints and pipe materials. A. Test Pressure. Unless otherwise noted, the designated piping system shall be The Neighborhoods of Holly Ridge Technical Specifications TS-10 Phase 1 Construction subjected to a test pressure of 150-psi measured at the lowest point in the line. B. Leakage Measurement. Measurement of leakage shall not be attempted until all rapped air has been vented and a constant test pressure has been established. After the pressure has stabilized, line leakage shall be measured by means of a suitable water meter installed in the pressure supply piping on the pipeline side of the force pump. C. Allowable Leakage. The term "Leakage", as used herein, shall be the total amount of water which must be introduced into the line during the leakage test to maintain the test pressure. No pipeline shall be accepted if and while it exhibits a leakage rate in excess of that determined by the following formula: Where Q = 0.0075 DLN Q = allowable leakage in gallons per hour D = nominal diameter of pipe in inches L length of section tested in thousand feet N square root of average test pressure in psi Whenever the pipeline to be tested contains pipe of different. diameters, the allowable leakage shall be calculated separately for each diameter and corresponding length of line. The resulting allowable leakage rates shall be added to obtain the total allowable leakage for the entire pipeline. All joints in piping shall be watertight and free from visible leaks during the leakage test. Each leak which is discovered within the correction period stipulated in the General Conditions shall be repaired by and at the expense of the Contractor regardless of any amount that the total line leakage rate, during the leakage test, may have been below the specified allowable leakage rate. If the leakage test indicates a line leakage rate exceeding the allowable, the Contractor shall locate and repair leaking joints and other defective items of work to the extent necessary to reduce the line leakage to an acceptable amount. 4.

The Contractor shall submit shop drawings of the proposed magnetic flowmeter for Engineer's approval. Installation shall be in accordance with manufacturer's recommendations. Materials shall include: Tube: carbon steel epoxy coated Sensor Material: Polyurethane Electrodes: 316 Stainless Steel I. Wet Well and Valve Vault Access Rungs Access shall be by means of aluminum manhole rungs cast in the concrete wet well wall. The manhole rungs shall be serrated for traction and a minimum of 12" wide. The top rung shall be maximum of 12" from the outside of the valve vault. Subsequent rungs shall be set in line vertically and spaced 12" on center within a maximum of 18" from the bottom of the valve vault. The Neighborhoods of Holly Ridge Technical Specifications TS-28 Phase 1 Construction SECTION 10 ELECTRICAL 1. GENERAL A. Electrical specifications for pump station only. B. Installation shall comply with the latest edition of the North Carolina State Building Code, Volume I and Volume X, National Electric Code, local building codes and ordinances and other national codes and ordinances.

The Neighborhoods of Holly Ridge Technical Specifications TS-29 Phase 1 Construction SECTION 11 EARTHWORK 1. GENERAL The work in this Section covers the furnishing of all labor, equipment and materials required to complete all excavation, backfilling, sheeting and shoring, dewatering, compacting, and disposal of excavated material to complete the work as indicated on the drawings and specified herein, and as directed by the Engineer. Provisions of this Section shall apply to all pipe work and be performed with requirements of local and state codes, with requirements of OSHA, and in accordance with federal requirements. 2. CHARACTER OF EXCAVATED MATERIAL The Contractor shall satisfy himself as to the nature of material that will be encountered during the course of the project. The submission of a Proposal shall be conclusive evidence that the Contractor has investigated the site and is satisfied as to the conditions to be encountered, as to the character, quality, and quantities of work to be performed and materials to be furnished, and as to the requirements of the Contract Documents. All excavation shall be unclassified regardless of the material encountered. 3. EXISTING UTILITIES Existing underground utilities and structures which are indicated on the drawings shall be located by the Contractor before any earthwork operations are begun in order to avoid conflicts and costly repairs of any utility. If utilities are to remain in place, adequate means of protection shall be provided during earthwork operations. Where unforeseen or incorrectly located utilities are encountered during excavation the Engineer or his representative must be informed immediately for conflict resolution. Where it is impossible to avoid conflict with existing utilities, the new construction shall be performed in a manner that will cause the least amount of interruption to the existing facility. The Contractor shall cooperate with the Owner, and public and private utility companies, in keeping their respective services and facilities in operation. 4. DEWATERING Pumping equipment shall be provided and employed to prevent water and subsurface or groundwater from accumulating or flowing into excavations and from flooding the project site and surrounding area. Water shall not be allowed to accumulate in excavations, as this could result in the softening of foundation bottoms, undercutting footings, and soil changes detrimental to stability of subgrades and foundations. The Contractor shall provide and maintain pumps, sumps, well points, suction and discharge lines, and other dewatering system components necessary to convey water away from the excavations. The disposal of conveyed water shall be diverted in such a manner that the natural drainage of the The Neighborhoods of Holly Ridge Technical Specifications TS-30 Phase 1 Construction area shall not be disturbed. All gutters, drains, sewers, storm drains and culverts shall be kept clean from surface drainage. 5. SHEETING, SHORING, AND BRACING The Contractor shall provide sheeting and bracing where necessary to prevent movement of the walls of excavation and/or to comply with regulations of the Occupational Safety and Health (OSHA) Act of 1970. Failure to adequately sheet and brace the walls of excavations shall be at the Contractor's risk and the Contractor shall be responsible for any damages to persons, pipelines, equipment, structures, or adjacent property caused by movement of the walls. When sheeting is used, additional width of trench shall be permitted to accommodate the thickness of the sheeting and to obtain the minimum sidewall clearance. Sheeting and Bracing are considered incidental to the construction of the sewer improvements. 6. EXCAVATION (General) Excavation for trenches and utility structures shall be made to indicated alignment and grade as required by field conditions. Vertical cuts shall be used whenever possible, but in unstable soils, trenches may be sloped from the top of the excavation to a point 3.0 feet above the top of the pipe with the width of the trench from this depth to the bottom of the ditch governed by A below. The bottom four inches of the excavation shall be excavated by hand. Bell holes shall be excavated by hand to insure that the pipe is properly supported for its entire length. A. Trench Width The maximum width of the trench shall be 24" plus the outside diameter of the pipe. This width shall also apply to sloped trenches for the last three feet above the top of the proposed pipe. B. Excavated Material Material excavated from the ditch shall be placed (whenever possible) in piles, a suitable and safe distance from the edge of the trench and along the side of the trench. When it is necessary to stockpile excavated material, it shall be the Contractor's responsibility to secure the stockpile areas. No classification of excavated materials will be made. Excavation and trenching work shall include the removal and subsequent handling of all materials excavated or otherwise removed in performance of the contract work, regardless of the type, character, composition, or condition thereof. Whenever the bottom of the trench is unstable and does not afford a good foundation., the Contractor shall immediately inform the Engineer or his The Neighborhoods of Holly Ridge Technical Specifications Ts-31 Phase 1 Construction representative, who will determine the method to be followed for removing such material as may be necessary and it's replacement with stabilization washed stone (#57). Subgrades for concrete structures and trench bottoms shall be firm, dense, and thoroughly compacted and consolidated, free from fines, muck and mud and sufficiently stable to remain firm and intact under the feet of the workers. Excavation for manholes and other appurtenances shall be sufficiently large to leave at least 12" clear between their outer surfaces and the line of the excavation or supporting timber. Any unauthorized excavation below the pipe or structure shall be filled with sand, gravel, or concrete at the expense of the Contractor. 7. BACKFILLING Back -filling shall progress as rapidly as the pipe laying, structural work, and testing permits. The trench shall be backfilled with approved material free from large clods or stones, (<2" spherical diameter). The initial backfill shall be carefully placed on both sides of the pipe at the same time and thoroughly tamped around the barrel of the pipe until enough material has been placed to provide two feet of cover above the top of the pipe. The remainder of the backfill shall be placed in well compacted, 6-inch layers using approved mechanical tampers. In no case shall the backfill material be placed in unequal layers on one side of the pipe that might cause pipe displacement. Backfilling of structural excavations shall not progress until the Engineer or his representative has reviewed and accepted the construction below finish grade including, where applicable, dampproofing, waterproofing, foundation subdrainage, perimeter insulation, removal of concrete formwork, shoring and bracing, and trash and debris, and the inspection, testing, approval and recording locations of underground utilities. TABLE 02.1 - ASTM 698 Fill, Embankment and Backfill Density Under Pavement 98% Standard Under structures and sidewalks 95% Standard Under grassed areas 90% Standard Adjacent to structures 90% Standard The Engineer shall decide, based upon laboratory tests, if warranted, the suitability of all material encountered. The top elevation of the trench shall be graded to the original grade that existed before excavation. In no case shall material such as old pavement, curbs, bricks or blocks be placed in the backfill. The Contractor shall be responsible for all settlement of backfill, fills, and embankments, which may occur within the one-year The Neighborhoods of Holly Ridge Technical Specifications TS-32 Phase 1 Construction warranty period. Any structures damaged by settlement shall be restored to their original condition by the Contractor at the Contractor's sole expense. A. Rock Cut: If rock is encountered in excavation, rock shall be removed to a depth of 8" below the bottom of the pipe. This 8 inches shall be refilled with select material. No additional payment will be made for rock or select backfill material but shall be considered incidental to installation of pipe. B. Muck: When it is encountered, and when ordered by Engineer's Representative, the Contractor will haul away and dispose of this unsuitable material. Approved backfill material shall be hauled in by the Contractor at his expense. Stabilization stone may be ordered and or authorized by the Engineer or his representative. 8. EXCESS MATERIAL Excess material that is suitable for backfill shall be disposed of at sites obtained by the Contractor. Should either the quantity or the composition of any excess or unsuitable material dictate that it be removed from the site, the Contractor shall obtain a place to accommodate it. Prior to removing the excess or unsuitable material to another site, the Contractor shall transmit to the Owner, with a copy to the property owner and the Engineer, a signed statement that suitable arrangements have been made with the property owner for placing the excess or unsuitable material. Neither the Owner nor the Engineer shall be held liable for noncompliance with the arrangement. 9. BORROW When the material excavated is not sufficient to meet the requirements for fill material, borrow shall be obtained by the Contractor. Borrow material shall be approved by the Engineer prior to placement. All imported materials will be the responsibility of the Contractor to locate, sample and testing by a qualified commercial testing laboratory. 10. SOIL TESTING AND INSPECTION SERVICE The Owner and the Engineer may check compaction of the backfill at anytime. For compacted earth and granular backfill in trenches and around structures, the Owner may employ an independent testing laboratory to make tests on site and will pay all costs for the first set of tests performed per lift. If compaction fails to meet specifications, all succeeding tests for that lift shall be at the Contractor's expense. The Neighborhoods of Holly Ridge Technical Specifications TS-33 Phase 1 Construction SECTION 12 EROSION AND SEDIMENT CONTROL 1. GENERAL The Contractor shall provide all labor, materials, tools and other items necessary to furnish and install silt fence and/or other sediment measures as shown on the erosion control plans. The Contractor shall also comply with the applicable regulations of all legally constituted authorities relating to pollution prevention, erosion and sediment control. The Contractor shall keep himself fully informed of all such regulations which in any way affect the conduct of the work, and shall at all times observe and comply with all such regulations. In the event of conflict between such regulations and the requirements of the specifications, the more restrictive requirements shall apply. The Engineer will limit the area over which construction operations are performed whenever the Contractor's operations do not make effective use of construction practices and temporary measures which will minimize erosion, or whenever construction operations have not been coordinated to effectively minimize erosion, or whenever permanent erosion control features are not being completed as soon as permitted by construction operations. The control measures shall begin prior to land disturbing activity, shall continue during construction with necessary maintenance until the disturbed land is stabilized. All areas of the site, which are disturbed, shall be protected. Temporary erosion control measures shall be removed at the conclusion of the project. Contractor shall provide ground cover within 30 calendar days after completion of construction within areas not otherwise used for storage of materials or construction of project. All work under this Section shall be in full compliance with the North Carolina Sedimentation Pollution Control Act of 1973 and all Rules and Regulations promulgated pursuant to the provisions of this act. A. EROSION AND SEDIMENT CONTROL MEASURES The Contractor shall take all measures as required to control erosion and sedimentation at the construction site, including borrow and waste areas and temporary access roads, and at off -site areas especially vulnerable to damage from erosion and sedimentation. All erosion and sediment control measures will be subject to approval by the Engineer. Control measures shall be provided as indicated on drawings and specified herein. Contractor shall maintain and/or replace erosion control measures throughout duration of project as may be required due to accumulation of sediment or deterioration of control devices. The minimum requirements for erosion control, as shown on the Drawings, have been approved by the Land Quality Section of the North Carolina Department of Environment and Natural Resources (NCDENR). Other methods of protecting The Neighborhoods of Holly Ridge Technical Specifications TS-34 Phase 1 Construction structures and facilities may be used at the option of the Contractor and subject to the approval of the NCDENR. Additional measures may become necessary upon field inspection by the NCDENR or other authorities having jurisdiction over the proiect. The Contractor shall acquire and maintain at the job site throughout the construction period a copy of Erosion and Sediment Control Planning and Design Manual published by the N.C. Sedimentation Control Commission and the Department of Natural Resources and Community Development (now NCDENR). Any changes required to accommodate subsequent conditions that may develop or become evident will be compensated for by a duly processed change order. 1) Critical areas to be protected from damage due to severe erosion and sedimentation, but not limited to, are as follows: a) Exposed and disturbed areas b) Steep cuts and fills c) Open piles of unstable excavated material d) Existing slopes e) Wetlands 2) Exposed Areas Work shall be scheduled so that areas subject to erosion are exposed for the shortest possible time. Only those trees, shrubs, and grasses shall be removed that are necessary for construction; those remaining shall be protected to preserve the aesthetic and erosion control values. Temporary on - site erosion structures or devices shall be located to preserve the existing landscape and to minimize erosion, including that from construction traffic. 3) Disturbed Areas Temporary protection shall be required for disturbed areas until final grading is completed and permanent vegetation is established, and shall consist of planting temporary grass cover or other vegetation when feasible. Other short- term protection shall include covering disturbed areas and topsoil piles with a mulch of hay, straw, or wood chips, stabilizing with netting, or covering with plastic sheets. Graded slopes and fills shall be limited to an angle and to lengths that will maintain stability and allow easy maintenance. Construction equipment shall not be operated in a way to make the land more susceptible to erosion, such as leaving tracks up and down slopes. Access roads shall be located and constructed so as to prevent erosion. 4) Stockpiles Stockpile areas shall also be selected and maintained by on -site personnel. Site selections and stockpile design shall incorporate sediment and erosion control considerations to prevent the potential direct production and delivery of The Neighborhoods of Holly Ridge Technical Specifications TS-35 Phase 1 Construction sediment to water ways, damage to vegetation that is part of the total sediment and erosion control plan, and the unnecessary destruction of trees that are selected for preservation. Temporary or interim stabilization of soil stockpiles shall be promptly instituted. The existence of critical slopes on stockpiles shall be avoided. Stockpiling in or immediately adjacent to diversion channels shall not be allowed because the stockpiled material will provide a direct and high volume source of sediment to storm runoff. Structural practices shall be installed on large stockpiles. Their design and implementation shall be accomplished by competent on -site personnel. 5) Dust Control The Contractor shall control dust throughout the life of the project within the project area and at all other areas affected by the construction of the project, including, but not specifically limited, unpaved secondary roads, haul roads, access roads, disposal sites, borrow and material sources, and production sites. Dust control shall not be considered effective where the amount of dust creates a potential or actual unsafe condition, public nuisance, or condition endangering the value, utility, or appearance of any property. The Contractor will not be directly compensated for any dust control measures necessary, as this work will be considered incidental to the work covered by the various contract items. B. SEDIMENT CONTROL MEASURES 1) Silt Fence Silt fencing may be constructed using standard strength synthetic filter fabric. Synthetic filter fabric shall be manufactured of propylene, nylon, polyester or ethylene yarn and shall be certified by the manufacturer or supplier as conforming to the following requirements: Physical Property Filtering Efficiency Tensile Strength Extra Strength (max.) Elongation Standard Strength Flow Rate Requirements 75% (min.) 20% 50lbs./ lin. in. (min.) 30lbs./ lin. in. (min.) 0.3 gal./sq.ft./min. (min.) *Requirements reduced by 50 percent after 6 months of installation. The Neighborhoods of Holly Ridge Technical Specifications TS-36 Phase 1 Construction Synthetic filter fabric shall contain ultraviolet ray inhibitors and stabilizers to provide a minimum of 6 months of expected usable construction life at a temperature range of 0-degree F to 120 degrees F. If burlap is used, it shall be 10-ounce per square yard fabric; and shall require hogwire backing on its entire length for stability. Posts for silt fences shall be either 4-inch diameter wood or 1.33 pounds per linear foot steel with a minimum length of 5 feet. Steel posts shall have projections for fastening wire to them. Silt fences shall be inspected immediately after each rainfall and at least daily during prolonged rainfall. Any required repairs shall be made immediately. Should the fabric on a silt fence decompose or become ineffective prior to the end of the expected usable life and the fence still be necessary, the fabric shall be replaced promptly. C. CHECK DAMS Rock check dams should be constructed according to the detail contained in the site work details in the drawings. Hand or mechanical placement will be necessary to achieve complete coverage of the ditch or swale and to ensure that the center of the dam is lower than the edges. While this practice is not intended to be used primarily for sediment trapping, some sediment will accumulate behind the check dams. Sediment should be removed from behind the check dams when it has accumulated to one-half of the original height of the dam. Check dams must be removed when their useful life has been completed. In temporary ditches and swales, check dams should be removed and the ditch filled in when it is no longer needed. In permanent structures, check dams should be removed when a permanent lining can be installed. In the case of grass -lined ditches, check dams should be removed when the grass has matured sufficiently to protect the ditch or swale. The area beneath the check dams should be seeded and mulched immediately after they are removed. Check dams should be checked for sediment accumulation after each significant rainfall. Sediment should be removed when it reaches one-half of the original height or before. Regular inspections should be made to ensure that the center of the dam is lower than the edges. Erosion caused by high flows around the edges of the dam should be corrected immediately. D. RIP RAP The rip rap shall be composed of a well -graded mixture down to the 1-inch size particle such that 50 percent of the mixture by weight shall be larger than the d50 The Neighborhoods of Holly Ridge Technical Specifications TS-37 Phase 1 Construction size as determined from the design procedure. A well -graded mixture as used herein is defined as a mixture composed primarily of the larger stone sizes but with a sufficient mixture of other sizes to fill the progressively smaller voids between the stones. The diameter of the largest stone size in such a mixture shall be 1.5 times the d50 size. The minimum thickness of the rip rap layer shall be 1.5 times the maximum stone diameter but not less than 6 inches. Stone for rip rap shall consist of field stone or rough unhewn quarry stone of approximately rectangular shape. The stone shall be hard and angular and of such quality that it will not disintegrate on exposure to water or weathering and it shall be suitable in all other respects for the purpose intended. The specific gravity of the individual stones shall be at least 2.5. A filter blanket is a layer of material placed between the rip rap and the underlying soil surface to prevent soil movement into or through the rip rap. Filter blankets should always be provided where seepage from underground sources threatens the stability of the rip rap. The subgrade for the rip rap or filter shall be prepared to the required lines and grades. Any fill required in the subgrade shall be compacted to a density approximating that of the surrounding undisturbed material. Brush, trees, stumps and other objectionable material shall be removed. Placement of the filter blanket should be done immediately after slope preparation. For granular filters the stone would be spread in a uniform layer to the specified depth. Where more than one layer of filter material is used, the layers should be spread so that there is minimal mixing of the layers. Placement of rip rap should follow immediately after placement of the filter. The rip rap should be placed so that it produces a dense well -graded mass of stone with a minimum of voids. The desired distribution of stones throughout the mass may be obtained by selective loading at the quarry, controlled dumping of successive loads during final placing, or by a combination of these methods. The rip rap should be placed to its full thickness in one operation. The rip rap should not be placed in layers. The rip rap should not be placed by dumping into chutes or similar methods that are likely to cause segregation of the various stone sizes. Care should be taken not to dislodge the underlying material when placing the stones. The finished slope should be free of pockets of small stone or clusters of large stones. Hand placing may be necessary to achieve the required grades and a good distribution of stone sizes. Final thickness of the rip rap blanket should be within plus or minus one quarter of the specified overall thickness. Once a rip rap installation has been completed, it should require very little maintenance. It should, however, be inspected periodically to determine if high flows have caused scour beneath the rip rap or dislodged any of the stone. If repairs are needed, they should be accomplished immediately. The Neighborhoods of Holly Ridge Technical Specifications TS-38 Phase 1 Construction E. EARTH BERMS AND/OR DIVERSION DITCHES AND/OR INTERCEPT DITCHES The primary purpose of these structures is to divert stormwater runoff to sediment traps or basins, thus preventing sediment from reaching streams, etc. The berm/ditch is usually constructed simultaneously by compacting the material just excavated from the ditch to form the berm. Earth berm/diversion ditches are normally 12 in. to 18 in. in width and have an average depth of 12 in. to 18 in. Side slopes should not exceed 2 horizontal to 1 vertical. If ditch slopes exceed 4 percent, they shall be stabilized with crushed stone. Whether the berms are temporary or permanent, they shall be stabilized immediately with seed or other acceptable stabilizer. The temporary sediment traps shall be removed, the areas regraded and reseeded permanently. F. SEDIMENT TRAPS Sediment traps are depressions which intercept sediment -laden runoff and retain sediment. The construction is mostly excavating to form a more shallow type earth containment system. Generally, a crushed stone filter berm outlet is sufficient for these traps. If earth berms are constructed, they shall be stabilized immediately. Where trenching occurs across an existing side slope, excavated materials shall be placed on the higher side of the trench in order for the open trench to assist in trapping of sediment. G. MAINTENANCE Sediment and erosion control practices will not function properly throughout their designed life span if they are not maintained. Periodic inspection shall be made at sufficiently frequent intervals to detect any impairment in the ability of the erosion control facilities installed as part of this plan to continue to function effectively. Responsibility for maintenance shall be assigned to an individual who has access to equipment, material and funds required to sustain the maintenance schedule. Most control structures require work to restore them after each storm. This maintenance shall be performed to allow the structure to continue to perform the function for which it was designed. Vegetative practices require maintenance. Vegetative cover established in the sediment and erosion control program shall not be allowed to deteriorate and become ineffective. A fertilization and reseeding program shall be established and carried out as the construction proceeds. Areas where failures have been The Neighborhoods of Holly Ridge Technical Specifications TS-39 Phase 1 Construction experienced in the establishment of vegetative protection shall be promptly treated. The re-establishment of permanent vegetative cover shall be initiated as soon as possible in an effort to keep the area requiring maintenance work to a minimum. Information shall be distributed to all persons on the construction site describing and stressing the importance of the proper installation and maintenance of the erosion and sediment control procedures included in this plan. The actions and language of supervisors on the project shall continually emphasize the seriousness and importance of sound erosion and sediment control procedures. The approved erosion and sediment control plan must be submitted by Contractor and any standard conditions relating to Soil Erosion and Sediment Control issued as part of any permits shall be available at the immediate site of construction activity at all times. Once permanent vegetative cover has been established, control devices including silt fences and stone dams shall be removed. After the construction phase is complete, permanent vegetation on the areas that have been disturbed shall be re- established as rapidly as possible. If the completion of the construction activities does not coincide with a season in which permanent vegetation can be started, an interim or temporary program is required. This shall include soil stabilization, mulching, or the establishment of filter strips. In any case, sediment and erosion controls shall be installed promptly and their maintenance assured. H. SANCTIONS Failure of the Contractor to fulfill any of the requirements of this article may result in the Engineer ordering the stopping of construction operations until such failure has been corrected. Such suspension of operations will not justify an extension of contract time. Failure on the part of the Contractor to perform the necessary measures to control erosion, siltation, and pollution will result in the Engineer notifying the Contractor to take such measures. In the event that the Contractor fails to perform such measures within 24 hours after receipt of such notice, the Engineer may suspend the work as provided above, or may proceed to have such measures performed. All erosion and sediment measures maintenance will be the responsibility of the Contractor. The Neighborhoods of Holly Ridge Technical Specifications TS-40 Phase 1 Construction SECTION 13 SEEDING AND TURFING 1. SCOPE This section shall include the furnishing of all labor, materials, equipment, and incidental items to seed and establish a turf on all areas disturbed by the pipe laying operations or any other earth disturbing operations. All materials shall be of the best commercial quality available for the purposes specified. Work consists of soil preparation, liming, fertilizing and seedbed preparation, grass seeding and mulching, complete, for all areas within limits of grading in accord with specifications and applicable drawings. 2. GRADING Rough grading shall be done as soon as all excavation required in the area has been back -filled. The necessary earthwork shall be accomplished to bring the existing ground to the desired finish elevations. Fine grading shall consist of shaping the final contours for drainage and removing all large rock, clumps of earth and waste construction material. It shall also include thorough loosening of the soil to a depth of 6-inches by plowing, discing, harrowing or other approved methods until the area is acceptable as suitable for subsequent seeding operations. 3. TOPSOIL After the subgrade has been fine graded to the satisfaction of the Engineer, topsoil shall be spread over the area to a uniform depth and density. The soil shall be uniformly compacted by a light roller to a depth not less than 4-inches, unless other depths are shown on the Plans. When finished, the surface shall conform to the finished grade shown or required and shall have a smooth pulverized surface at the time of seeding. Any irregularities shall be corrected before the fertilizer and seed is placed. Any settlement or displacement of the topsoil shall be restored to the established lines and grades at the Contractor's own expense. Topsoil removed from the excavations, which is approved by the Engineer for use, shall be placed in the locations and to the depth shown, specified or directed. In the event the topsoil removed during excavation is unsatisfactory or is inadequate to cover the requested areas, the Contractor shall furnish the required quantity of satisfactory topsoil from approved sources off the site. Topsoil furnished from areas off the site shall be a friable clay loam free from stones, roots, sticks, and other foreign substances. Such topsoil shall pass a 1/4-inch screen. Topsoil shall not be delivered or placed in a frozen or muddy condition. 4. LIME The quality of lime and all operations in connection with furnishing this material shall comply with the requirements of the North Carolina Department of Agriculture. The Neighborhoods of Holly Ridge Technical Specifications TS-41 Phase 1 Construction During the handling and storing, the lime shall be cared for in such a manner that it will be protected against hardening and caking. Any hardened or caked lime shall be pulverized to its original condition before being used. No lime, fertilizer, or seed shall be applied when the wind is strong or when the soil is extremely wet or otherwise unworkable. No rolling shall be done if precipitation after seeding should make the operation detrimental to the seedbed. Liming shall be done immediately after grading has reached the final "smoothing" stage, even though actual seeding may not be done until several months later. Lime shall be used at 2 tons per acre and shall be spread evenly by means of approved mechanical spreaders or distributors. When lime is distributed by commercial liming dealers, sales slips showing the tonnage delivered shall be filed with the Engineer and shall show the full tonnage required for the acres treated. Lime shall be incorporated in the top 2 to 3 inches of soil by harrowing, disking, or other approved means. Lime shall be agriculture grade ground dolomitic limestone. It shall contain not less than 85 percent of the calcium and magnesium carbonates and shall be of such fineness that at least 90 percent will pass a Number 10 sieve and at least 50 percent will pass a Number 100 sieve. 5. FERTILIZER Fertilizer shall be spread not more than two weeks in advance of seeding. Fertilizer shall be of a formula specified at the rate of 1000 pounds per acre, for 10-10-10. To assure full application rate, the acreage in an area to be fertilized during the day shall be determined, and the required fertilizer delivered to the area. All such fertilizer shall be protected from damage by weather or otherwise until used. Lump fertilizer shall be thoroughly pulverized before placing in the distributor. Even distribution shall be accomplished with approved mechanical spreaders, by spreading half of the rate in one general direction, and the other half at right angles to the first. Within 24 hours after spreading, the fertilizer shall be incorporated into the top 2 to 3 inches of soil by disking, harrowing or other approved methods to provide an adequate seedbed. Upon written approval of the Engineer a different grade of fertilizer may be used, provided the rate of application is adjusted to provide the same amounts of plant food. 6. SEEDING The mixture of seed in all disturbed area shall be the following: 1. April 1 —July 15: 100 pounds/acre Pensacola Bahiagrass Seed shall have been approved by any agency approved by the Engineer before being sown, and no seed will be accepted with a date of test more than eight months prior to the date of sowing. Such testing, however, will not relieve the Contractor from responsibility of furnishing and sowing seed that meets these specifications at the time of sowing. When a low percentage of germination causes the quality of the seed to fall below the minimum pure live seed specified, the Contractor may elect, subject to the The Neighborhoods of Holly Ridge Technical Specifications TS-42 Phase 1 Construction approval of the Engineer, to increase the rate of application sufficiently to obtain the minimum pure live seed content specified, provided that such an increase in the rate of application does not cause the quantity of noxious weed seed per acre or square yard, as the case may be, to exceed the quantity that would be allowable at the regular rate of application. During handling and storing, the seed shall be cared for in such a manner that it will be protected from damage by heat, moisture, rodents, or other causes. Immediately following preparation of the seedbed, the seed shall be uniformly applied by a mechanical spreader. The seed shall be raked lightly into the surface and rolled with a light hand lawn roller weighing not more than 100 pounds per foot of width. Seeded areas shall be sprinkled with a fine spray in such a manner as not to wash out the seed. Seeding shall be done on a "calm" day and only with the approval of the Engineer or his representative. The Contractor shall water as necessary and keep all seeded areas in good condition, and re -seed if and when necessary, until a smooth and uniform grassed area is established over the entire area seeded and shall maintain these areas in an approved condition until final acceptance of the Contract. On slopes, the Contractor shall provide against washouts by an approved method. Any washouts which occur shall be re -graded and re -seeded until a grass area is established. 7. MULCHING Straw mulch shall be threshed plant residue of oats, wheat, rye, free from matured seed of obnoxious weeds or other species that would grow and be detrimental to the specified grass. It shall be spread uniformly at a rate of two (2) tons per acre in a continuous blanket over the areas specified not later than two (2) days after seeding. Thickness of the covering shall be adequate to hold the soil but sufficiently loose and open to favor the development of the grass. Mulch shall be held in place by applying a sufficient amount of asphalt or other approved binding material to assure that the mulch is properly held in place. The rate and method of application of binding material shall meet the approval of the Engineer or his representative. Where binding material is not applied directly with the mulch, it shall be applied immediately following the mulch application. An extra application may be necessary in the bottom of drainage swales to prevent erosion. 8. MAINTENANCE Begin maintenance immediately after each portion of grass is planted and continue for eight (8) weeks after all grass planting is completed. The Contractor shall be responsible for maintenance, protection, repairing and resulting reseeding and refertilization at the end of the eight (8) week grass maintenance period. No direct payment will be made for any maintenance. The Neighborhoods of Holly Ridge Technical Specifications TS-43 Phase 1 Construction 9. FINAL ACCEPTANCE All areas grassed will be acceptable provided all requirements, including maintenance, have been complied with and a healthy, uniform stand of specified grass has been established, free of weeds, bare spots, and surface irregularities. The Engineer and the Contractor shall inspect the seeding work at the time of the final inspection of the project. The condition of the seeded areas will be noted and a determination will made whether maintenance shall be continued in any part beyond the date of final acceptance. The Neighborhoods of Holly Ridge Technical Specifications TS-44 Phase 1 Construction SECTION 14 CAST -IN -PLACE CONCRETE 1.

WEATHER LIMITATIONS -Stabilized aggregate base courses shall not be constructed when the atmospheric temperature is below 35 degrees F. When the temperature falls below 35 degrees F., it shall be the responsibility of the Contractor to protect all areas of completed base course against any detrimental effects, by methods approved by the Engineer. Any areas of completed base course that are damaged by freezing shall be reconditioned, reshaped and recompacted by the The Neighborhoods of Holly Ridge Technical Specifications TS-61 Phase 1 Construction Contractor in conformance with the requirements of this specification without additional cost to the Owner. 04. PREPARATION OF SUBGRADE Prior to constructing the base course, the previously constructed subgrade shall be dry and cleaned of all foreign substances. The surface of the subgrade will be inspected by the Engineer for adequate compaction and surface tolerances. Any ruts or soft -yielding spots that may appear in the subgrade, any areas having inadequate compaction, and any deviations of the surface from the requirements set forth therein shall be corrected by loosening, removing, and adding approved material, reshaping and recompacting the affected areas to line and grade, and to the specified density requirements at the Contractor's expense. Any unsuitable material or subgrade will be included in the unit price of respective pavement. 05. PLACING AND MIXING OF MATERIAL The base material shall not be dumped directly onto the subgrade from trucks. Dumping shall be either on old pavement or on material already dumped and spread, and material shall be spread by means of bulldozers or graders of a size suitable for such spreading. Spreading will begin at the point nearest the source of supply and all hauling shall be over the material dumped and spread. Constant machining shall accompany the traffic in order to prevent rutting and to provide for even compaction. Hauling shall be distributed over the entire width of the street. Any portions of the layer spread that become segregated shall be remixed by scarifying and the addition of new material to produce a satisfactory blend of materials. 06. MANIPULATION AND COMPACTION After sufficient material has been placed on the subgrade to obtain the specified thickness of base, it shall be well rolled and machined until thoroughly compacted. Frequent template checks shall be made to insure that a minimum amount of patching is necessary after complete compaction is secured. If patching is required, the base material in place shall be scarified to insure adequate bonding together of previously placed base and new material. The base course shall be compacted its full depth to the minimum density requirements listed in Table 610-4 of the DOT Standard Specifications for Asphalt Bases and Pavements and density at optimum moisture, as determined by ASTM D698, latest revision.

The Neighborhoods of Holly Ridge Technical Specifications TS-62 Phase 1 Construction 07. TRANSPORTATION OF BITUMINOUS MIXTURE The bituminous mixture shall be transported from the paving plant to the site in trucks having tight, clean, smooth beds which have been oiled with a minimum amount of approved thin oil to prevent adhesion of the mixture to the truck bodies. Each load shall be covered with canvas or other suitable material of ample composition and size to protect it from the weather and to prevent the loss of heat. ' Deliveries shall be made so that spreading and rolling of all the mixture prepared for a day's run can be completed during daylight, unless artificial light satisfactory tot he Engineer is provided. The mixture shall be delivered to the area to be paved in such manner that the temperature at the time of dumping into the spreader will not be less than that hereinafter specified. Any loads wet excessively by rain will be rejected by the Engineer. Hauling over freshly laid material will not be permitted. 08. PLACING ASPHALTIC SURFACE COURSE The Contractor shall furnish all equipment, tools, machinery and plant necessary for handling, preparing, manufacturing and executing completion of this work. No surface course shall. be laid when the temperature is less than 35 degrees F. in the shade away from artificial heat. Prior to delivery of surface course materials, the base course shall be completed for receiving the surface course material, and shall be kept free from traffic, with the exception of the mixture vehicles and those other vehicles necessary for the placing of the pavement. The pavement shall be placed only when weather conditions are suitable. Upon arrival on work, the mixture shall be laid by an approved type paving machine and finished to the proper grade for rolling. Asphalt mixtures that have temperatures of less than 225 degrees F., when dumped into the mechanical spreader, will be rejected. The mechanical spreader shall be adjusted and the speed regulated so that the surface of the course will be smooth and of such depth that, when completed, it will conform to the cross section, grade and contour shown on the drawings or as specified. Placing of the mixture shall be as nearly continuous as possible. A sufficient number of experienced shovelers and rakers shall follow the spreading machine, adding hot mixture and raking the mixtures as required to produce a course that, when completed, will conform to all requirements specified herein. In areas where the use of machine spreading is impractical, the mixture may be spread by hand. The mixture shall be distributed into place from the dump beds by means of hot shovels and then spread with hot rakes in a uniformly loose layer of such thickness that, when compacted. it will conform to the required grade and thickness. The loads shall not be dumped any faster than they can be properly handled by the shovelers and rakers. Prior to the placing of additional asphalt to bring up to grade low places in the surface existing after the initial placing of asphalt, the area to be filled shall be thoroughly scarified by asphalt rakes. After additional mixture is placed it shall be raked carefully so as to be slightly higher than the surrounding area, so that when properly compacted, it will be at the same grade as the surrounding area. The Neighborhoods of Holly Ridge Technical Specifications TS-63 Phase 1 Construction Contact surfaces of forms, curbing, gutters, manholes, etc., shall be painted with a thin uniform coating of cut back asphalt just before the surface mixture is placed against them. Immediately adjacent to the headers, flush curbing, gutters, liners, and other structures the surface course rnixture shall he spread uniformly high so that after compression it will be slightly above the edge of such structures. 09. COMPACTION ASPHALT SURFACE COURSE The compression and compaction of the course shall be secured with a ten -ton tandem roller. All rollers used shall be in first class condition and shall weigh not less than 200 pounds to the inch width of wheel tread (Contact surface). Each roller shall be in the charge of a competent and experienced roller operator and shall be kept in continuous operation during the placing and finishing of the asphalt surface course until cooled. Rolling will start longitudinally at the side and proceed towards the center of the pavement, overlapping on successive trips at least one-half the width of the roller. The pavement surface shall, after initial compaction, be subjected to diagonal rolling in a weaving fashion so that tall areas are rolled in two directions in addition to the initial longitudinal sealing. In large areas where the width permits, the pavement shall also be rolled at right angles to the original longitudinal sealing. Rolling shall be continued until all roller marks are elirininated. The motion of the roller shall at all times be slow enough to avoid displacement of the hot mixture, and any displacement occurring as a result of the roller or from any other cause shall at once be corrected by the use of rakes, replacing the mixture where necessary. Rolling shall proceed immediately after placing in order to obtain maximum compression and density and, in the event that the rolling operation is not able to properly keep up with the placing, the mechanical spreader shall stop and no pavement shall be laid until the rolling is caught up. It is suggested that two rollers, at a minimum, be in operation during the placing of pavement and more, if required. Along curbs, headers and similar structures and all places not readily accessible to the roller, the surface mixture shall be thoroughly compacted with hot tamps, small rollers, smoothing irons, etc., in order to produce the desired finish and seal joints. Joints shall be made at the end of the day's run by use of header planks, and additional planks, shall be placed on the base course beyond this header in such a fashion as to support the roller off the base course, sand or any other surface during the compaction stage. 10. TACK COAT A tack or squeegee coat of hot asphalt grade RS-1 h shall be applied to existing pavement surface where and as directed by the .Engineer prior to placing the surface course thereon. This coat shall be applied in quantity not to exceed 1/10 gallon per square yard and in a manner which has been approved by the Engineer. All castings, the gutter edge and other surfaces which payment rests against shall be painted with tack coat material by way of a hand brush prior to the placing of the surface course. All asphaltic cement or other materials which discolor the surface of concrete structures and items which are spilled or placed The Neighborhoods of Holly Ridge Technical Specifications Ts-64 Phase 1 Construction on such surfaces shall be removed at the Contractor's expense, and his inability to remove such foreign and disfiguring stains shall result in the complete removal of the structures so stained or disfigured, and these removed structures or surfaces shall be replaced at his expense. Particular care shall be taken to prevent tack coat from getting on gutter areas. When resurfacing existing pavements, the existing pavement shall be tacked with RS - 1 h asphalt at the rate of 0.03 gallons per square yard to 0.10 gallons per square yard. Application of the tack coat shall be allowed sufficient time to "break" prior to beginning the resurfacing operation. 11 PRIME COAT All base materials shall receive a prime coat of RC - 30 or MC - 30 asphalt. Application rate shall be from 0.2 to 0.3 gallons per square yard (application temperature 90 to 130 degrees F.) This prime coat shall be applied at least 24 hours prior to laying asphaltic concrete surface. If, at the end of 24 hours the prime coat has not cured properly, additional time shall be allowed so that the prime coat does not "pick-up" when driven on. Sufficient moisture shall be applied to the base prior to the priming to insure proper penetration of prime coat, and to avoid conglobating of prime coat on extremely dusty areas of base. 12 CONNECTIONS WITH EXISTING FACILITIES Where the bituminous pavement is to be connected with an existing driveway and/or roadway surface, or other facility, the Contractor will be required to modify the existing grade in such a manner as to produce a smooth connection. Where it is necessary to remove existing asphalt surfaces or concrete surfaces to provide proper meet lines and riding surfaces, the Contractor shall burn or chip the existing surface so that there will be sufficient depth to provide a minimum of 1 inch of asphalt concrete, and the waste material shall be disposed of to the satisfaction of the Engineer. Prior to placing the asphalt concrete, these areas shall be tacked. Meet lines shall be straight and the edges be vertical. The edges of meet line cuts shall be painted with liquid asphalt or emulsified asphalt prior to placing asphalt concrete. After placing the asphalt concrete, the meet line shall be sealed by painting with a liquid asphalt or emulsified asphalt and immediately covered with clean, dry sand. Prior to laying the second strip of asphalt concrete pavement, the edge of the first strip laid and other contact surfaces such as curbs, manhole frames, and similar materials shall be painted with emulsified asphalt or liquid asphalt to provide closely bonded watertight joints. This work shall be done in a manner that will prevent staining adjacent surfaces not intended to be coated. The Neighborhoods of Holly Ridge Technical Specifications Ts-65 Phase 1 Construction 13. ADJUSTMENT OF EXISTING MANHOLES, MONUMENT BOXES, VALVE BOXES Work covered in this section shall consist of raising or lowering existing manhole covers, monument boxes, valve boxes, sewer clean -out boxes and inlet frames to match the grade of the propose* o�.eday. The walls of existing manholes shall be removed to sufficient depth to provide for adjustment and the adjustment shall be made with masonry brick, mortar and portland cement concrete. Water valve and sewer service clean -out boxes shall be adjusted and placed on a footing as per the Standard Detail. Sewer main line clean -outs shall be adjusted and placed on a footing as per Standard Details. Monument boxes shall be adjusted and placed on a footing as per Standard Details. 14. PROTECTION AND TESTING OF ASPHALTIC SURFACE COURSE Sections of newly placed and compacted surface course shall be barricaded and protected from all defects for a period of at least eight hours until they have become properly hardened by cooling. The finished surface of the pavement shall be smooth and true to the established crown and grade. Any defective places shall be corrected after the first roller pass. When a deficiency is located, sufficient checks in the area immediately surrounding it shall be made to determine its exact limits. Depressions shall be corrected by loosening the material with rakes to a depth of approximately one-half inch. Hot material from the bin of the finishing machine or a full hot truck shall be added, raked, smooth, and compacted. Where the irregularity is in the form of a knot, the material shall be loosened to a depth somewhat greater than the final desired grade, the excess material removed, the area raked smooth and compacted. The surface shall be checked by use of a ten foot straight edge applied parallel to the center of the pavement and any place or areas that very more than one-fourth of an inch as measured from the bottom of the straight edge to the surface shall be corrected as herein before specified. After completion of the final rolling, the smoothness of the pavement shall be checked, and any irregularities that exceed the specified tolerances or that retain water on the surface shall be corrected by removing the defective work and replacing with new material, as directed by the Engineer, without additional cost to the Owner. A. PAVEMENT SAMPLES The Contractor shall furnish for test, a sample cut from each completed street. The areas of base and surface courses so removed shall be replaced with new mixture and finished so as to conform with the surrounding pavement by the Contractor at no additional cost. The Neighborhoods of Holly Ridge Technical Specifications Ts-66 Phase 1 Construction 15. MEASUREMENT AND PAYMENT No separate measurement and payment will be made for restoration of disturbed asphalt (such as raising manhole cover, meter boxes, and valve boxes, as a result of construction or for the :carious depths of stone subgrade. The mix design, subgrade thickness and asphalt testing, as specified, shall be included in the Lump Sum Bid for the project.

Pr jcet: No. 11081 Subject: Infiltration Testing. Neighborhoods of Holly Ridge Holly Ridge, North Carolina Dear Mr. Cook: Engineering C:onsuiting Scxvices, Ltd. (ECS) recently conducted an. infiltration evaluation for the proposed commercial site located near the intersection of NC Hwy 17 and NC Hwy 50 in IToily Ridge, North Carolina. This letter, with attachments, is the report of our investigation. Ne➢d lirivestigation,s On October 20, 2004, ECS conducted an investigation of the subsurface soil and ground water conditions at: the approximate locations indicated on the provided Site Sketch. The purrose of our invcstigation was to determine the subsurface; soils and the infiltration rate of the subsurface; soils. We investigated the subsurf.'ace soil and ground water conditions by drilling seven hand auger boring to a depth of approximately five to seven feet below the existing ground. surface at t:he approximate locations indicated on lho site sketch. The test locations were selected by Mr. Jeff Holland of Cavanaugh and Associates. We visually'classifed the subsurface aoi,ls, The atutched Infiltration Evaluation :Form provides a summary of the subsurface conditions encountered at the hand auger boring locations and the result of our infiltration tests. Our field classifica.ti.ons indicate that, the subsurface soils 3.1. the test locations consisted of silty fine to medium sands, fine to meditate sands, acid claystraw. Ground water was encountered deptbs ranging from 6 to 60'inches below prescut: site grade. We conducted five infiltration tests near hared auger boring locations #1, #2, #3, ##6 and 47. Infiltration tests were not conducted at locations JA and #5 due to shallow gmundwater. The infiltration test was conducted within. the upper stratum of sands at 24 inches above seasonal high ground water levels. The result of the test is suni.marized on the attached lnfiltl•ation Evaluation sheet and is also listed below. P. O. Box 10434, Wilmington, NC 28404 a (910) 686-9114 9 FAX (910) 686-9666 .

Infiltration test #2 was performed at a depth of, approximately 24 inches below existing grade and indicated an infiltration rate of 0.075 inches per minute (4.5 in/hr). Infiltration test. #3 was perforrtled at a depth of approximately 24 inches below existing gra(I.e and indicated an infiltration ,rate of 0.225 inches per minute (I3.5 in%hr). Infiltration test #6 was performed at a depth of approximately 24 inches below existing grade anal indicated an infiltration rate of 0.05 inches Per minute (3 inlhr). Infiltration (.est #7 was performed at a depth of approxitria,(vly-G inches below existing grade and indicated an infiltration rate of 0.025 inches per minute (1.5 in/hr). Please see the attached Sttc sketch for the infiltration test location. Evaluations :Based on observations in the hand auger borings, it is our opi')JOn that the seasonal high groulad water level at the infiltration test locations ranges from a. depth of approximately 30 inches to 54 inches below existing grade. The lower strattxtn of relatively free -draining .fine to inediuln sands is expected to have infiltration rates considerably greater than the controlling infiltration rates .for the shaDow qoils. Tt: is s.lso likely that the seasonal high groundwater conditions and in.(il.lrtition rates can vaiy across the site due to naturally occurring soil type and because of (.he surface topography.
