The building is presently no longer used. Renovation plans are in the design process for converting the building and the site into use as the location of the base's college programs. The building and its associated surrounding sidewalks will remain in their present configuration. The front parking area will be demolished, regraded, repaved and enlarged. An additional parking area will be constructed on the northern side of the site. The existing Building 825 has a roof drainage system which collects roof runoff and discharges to the rear of the building away from the drainage watershed associated with the new construction. The runoff from the front parking and drive areas, the front grassed areas, the side parking area and the western lane of the existing Stone Street are all collected for treatment. The project built -upon area is 56.6%. The stormwater treatment system for the site is a wet detention pond sired for 90% TSS removal. The pond will have a four foot permanent pool depth. The minimum required permanent pool surface area is 22,595 square feet. The provided surface area is 25,600 square feet. The pond is designed to treat the runoff associated with the one -inch storm in less than five days. The pond outlet structure will discharge into a 3:1 side sloped grassed swale prior to discharge into an existing manmade drainage ditch. The stormwater detention pond is designed with a 3:1 length to width ratio and will incorporate a single forebay. All runoff will enter on the opposite end from where it will discharge. Approximately 60% of the stormwater runoff from this project will be pretreated in grass lined drainage swales prior to discharging into the stormwater detention pond. Section 404 Wetlands exist approximately 90 feet east of the proposed stormwater detention pond. This project will not adversely impact these wetlands. AVOLIS ENGINEERING, P.A.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: Please specify the wetland species to be planted on the 6:1 shelf of the pond. 2. Please provide dimensions on the pond and label the permanent pool elevation. Please provide dimensions and bearings on the property lines. Please provide separate tables for the forebay and main pool elevations, areas, and volumes. I am unsure if the table in the calculations is for the entire pond or just the main pond. 5. On Item 4 of Section III of the Wet Detention Basin Supplement, please provide the actual depth, not the elevation, of the sediment removal. This will allow the sediment depth to be determined without needing a reference elevation. I am returning the original application to the engineer for this change to be made. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to July 5, 2003, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. N. C.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: I . Please specify the wetland species to be planted on the 6:1 shelf of the pond. 2. Please provide dimensions on the pond and label the permanent pool elevation. Please provide dimensions and bearings on the property lines. 4. Please provide separate tables for the forebay and main pool elevations, areas, and volumes. I am unsure if the table in the calculations is for the entire pond or just the main pond. On Item 4 of Section III of the Wet Detention Basin Supplement, please provide the actual depth, not the elevation, of the sediment removal. This will allow the sediment depth to be determined without needing a reference elevation. I am returning the original application to the engineer for this change to be made. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to July 5, 2003, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. N. C.

Excavate borrow pits to afford adequate drainage. Overburden and other soil material shall be used for special purposes. 3.5 FILLING AND BACKFILLING 3.5.1 Subgrade Preparation Scarify the underlying subgrade surface to a depth of 6 inches before the fill is started. Step, bench, or break up sloped surfaces steeper than one vertical to 4 horizontal so that the fill material will bond with or be securely keyed to the existing material. Scarify existing surface to a minimum depth of 6 inches if subgrade density is.less than the degree of compaction specified and recompact. When the subgrade is part fill and part excavation or natural ground, scarify the excavated or natural ground portion to a depth of 6 inches and recompact as specified for the adjacent or overlying fill. Compact with equipment well suited to the soil being compacted. Moisten or aerate material as necessary to provide the moisture content that will readily facilitate obtaining the specified compaction with the equipment used. . 3.5.2 Fill and Backfill Beside Structures Place required backfill material adjacent to structures and compact in a manner that prevents wedging action or eccentric loading upon or against SECTION 02301 Page 9 CONSTRUCT PARKING LOTS, BUILDING 825, MCB CAMP LEJEUNE 05023543 the structures. Step or serrate slopes bounding or within areas to be backfilled to prevent sliding of the fill. Moisten or aerate material as necessary to provide the moisture content that will readily facilitate obtaining the specified compaction with the equipment used. Do not place material on surfaces that are muddy, frozen, or contain frost. Do not use equipment for backfilling operations or for the formation of embankments against structures that will overload the structure. 3.5.3 Controlled Fill and Controlled Backfill Place controlled fill and controlled backfill under concrete slabs not pile supported, and pavements in loose lifts of 6 inches. Do not place material on surfaces that are muddy, frozen, or contain frost. Compact with equipment well suited to the soil being compacted. Moisten or aerate material as necessary to provide the moisture content that will readily facilitate obtaining the specified compaction with the equipment used. Compact each lift as specified herein before placing the overlaying lift. Compaction shall be accomplished continuously over the entire area. Sufficient passes shall be made to ensure that specified density is obtained. 3.5.4 General Fill, and General Backfill Construct fill, backfill and embankment at the locations and to lines and grades indicated. Use only approved materials in constructing fill on the prepared subgrade. Place satisfactory material in horizontal lifts not exceeding 8 inches in loose depth. Do not place material on surfaces that are muddy, frozen, or contain frost. Compact with equipment well suited to the soil being compacted. Moisten or aerate material as necessary to provide the moisture content that will readily facilitate obtaining the specified compaction with the equipment used. Compact each lift as specified before placing the overlaying lift. 3.5.5 Final Backfill for Utilities Construct backfill (final backfill) for storm drains, manholes, utility lines, and other utility appurtenances using the material and compaction requirements specified herein for the adjacent or overlying work. 3.5.6 Weather Limitations Fill and backfill shall not be constructed when weather conditions detrimentally affect the quality of the finished course. Place fill and backfill only if the atmospheric temperature is above freezing in the shade and is rising. Do not construct fill and backfill in the rain or on saturated subgrades. If weather conditions are windy, hot or arid, with high rate of evaporation, schedule the placement in cooler portions of the day and furnish equipment to add moisture to the fill or backfill during and after placement. 3.6 BORROW Strip the top 12 inches of soil material from designated borrow area and stockpile.

Seeding and mulching shall be performed on all earth areas disturbed by construction. Provide seeding and mulching of all areas. The Contractor shall adapt his operations to variations in weather or soil conditions as necessary for the successful establishment and growth. The quantity of mowing to be performed will be conditions which occur during the construction quantity of mowing may be increased, decreased, the direction of the Contracting Officer. Such not be considered as alterations in the details in the character of the work. PART 2 PRODUCTS 2.1 FERTILIZER affected by the actual of the project. The or eliminated entirely at variations in quantity will of construction or a change The quality of all fertilizer and all operations in connection with the furnishing of this material shall comply with the requirements of the North Carolina Fertilizer Law and with the rules and regulations, adopted by the North Carolina Board of Agriculture in accordance with the provisions of said law, in effect at the time of sampling. Fertilizer shall be 10-10-10. Dry fertilizer shall have been manufactured from cured stock. Liquid fertilizer shall be stored and cared for after manufacture in a manner that will prevent loss of plant food values. 2.2 LIMESTONE The quality of all limestone and all operations in connection with the furnishing of this material shall comply with the requirements of the North Carolina Lime Law and with the rules and regulations adopted by the North Carolina Board of. Limestone shall be agricultural grade ground Dolomitic limestone. All limestone shall contain not less than 90 percent calcium carbonate equivalents. Dolomitic limestone shall contain not less than 10 percent of magnesium. Dolomitic limestone shall be so graded that at least 90 percent will pass through a U.S. Standard 20 mesh screen, and at least 35 percent will pass through a U.S. Standard 100 mesh screen. 2.3 SEED The quality of all seed and all operations in connection with the furnishing of this material shall comply with the requirements of the North Carolina Seed Law and with the rules and regulations adopted by the North SECTION 02823 Page 1 CONSTRUCT PARKING LOTS, BUILDING 825, MCB CAMP LEJEUNE 05023543 Carolina Board of Agriculture. Seed shall have been approved by the North Carolina Department of Agriculture before being sown. No seed will be accepted with a date of test more than 8 months prior to the date of sowing, excluding the month in which the test was completed. Seed mix by weight shall be 50% KY-31 Fescue, 20% Annual Rye, 30% Unhulled Bermuda. 2.4 MULCH FOR EROSION CONTROL Mulch for erosion control shall consist of grain straw or other acceptable material, and shall have been approved by the Contracting Officer before being used. All mulch shall be reasonably free from mature seed bearing stalks, roots, or bulblets. Material for holding mulch in place shall be asphalt or other approved binding material. 2.5 MATTING FOR EROSION CONTROL 2.5.1 General Matting for erosion control shall be or excelsior matting. Other acceptable material manufactured especially for erosion control may be used when approved by the Contracting Officer in writing before being used. Matting for erosion control shall not be dyed, bleached, or otherwise treated in a manner that will result in toxicity to vegetation. 2.6 WATER Water used in the planting or care of vegetation shall meet the requirements of Class C fresh waters as defined in 15 NAC 2B.0200. PART 3 EXECUTION 3.1 GENERAL REQUIREMENTS The work shall be performed immediately upon completion of earthwork areas. No exception will be made to this requirement unless otherwise permitted in writing by the Contracting Officer. Upon failure or neglect on the part of the Contractor to coordinate his grading with seeding and mulching operations and diligently pursue the control of erosion and siltation, the Contracting Officer may suspend the Contractor's operations until such time as the work is coordinated in a manner acceptable to the Contracting Officer. 3.2 SEEDBED PREPARATION The Contractor shall cut and satisfactorily dispose of weeds or other unacceptable growth on the areas to be seeded. The soil shall then be scarified or otherwise loosened to a depth of not less than 3 inches except as otherwise provided below or otherwise directed by the Contracting Officer. Clods shall be broken and the top 2 to 3 inches of soil shall be worked into an acceptable seedbed by the use of soil pulverizers, drags, or harrows; or by other methods approved by the Contracting Officer. All rock and debris 3 inches or larger shall be removed prior to the application of seed and fertilizer. On cut slopes that are 2:1 and steeper, both the depth of preparation and the degree of smoothness of the seedbed may be reduced as permitted by the Contracting Officer, but in all cases the slope surface shall be scarified, grooved, trenched, or punctured so as to provide pockets, ridges, or trenches in which the seeding materials can lodge. On cut slopes that are either 2:1 or steeper, the Contracting Officer may permit the preparation of a partial or complete seedbed during SECTION 02823 Page 2 CONSTRUCT PARKING LOTS, BUILDING 825, MCB CAMP LEJEUNE 05023543 the initial grading of the slope. If at the time of final seeding and mulching operations such initial preparation is still in a condition acceptable to the Contracting Officer, additional seedbed preparation may be reduced or eliminated. Seedbed preparation within 2 feet of the edge of any pavement shall be limited to a depth of 2 to 3 inches. The preparation of seedbeds shall not be done when the soil is frozen, extremely wet, or when the Contracting Officer determines that it is an otherwise unfavorable working condition. 3.3 LIMESTONE AND FERTILIZER Limestone may be applied as a part of the seedbed preparation, provided it is immediately worked into the soil. If not so applied, limestone and fertilizer shall be distributed uniformly over the prepared seedbed and then harrowed, raked, or otherwise thoroughly worked into the seedbed. Apply fertilizer at the rate of 25'pounds per 1000 square feet. Apply lime at the rate of 40 pounds per 1000 square feet. Application equipment for liquid fertilizer, other than a hydraulic seeder, shall be calibrated to ensure that the required rate of fertilizer is applied uniformly. 3.4 SEEDING Seed shall be distributed uniformly over the seedbed at the rate of 2 pounds per 1000 square feet. Seed shall be harrowed, dragged, raked, or otherwise worked so as to cover the seed with a layer of soil. The depth of covering shall be 1/4 inch. when a hydraulic seeder is used for application of seed and fertilizer, the seed shall not remain in water containing fertilizer for more than 30 minutes prior to application unless otherwise permitted by the Contracting Officer. Immediately after seed has been properly covered the seedbed shall be compacted in the manner and degree approved by the Contracting Officer. 3.5 MULCHING All seeded areas shall be mulched. Grain straw or excelsior mat may be used as mulch at any time of the year. Mulch shall be applied within 24 hours after completion of seeding unless otherwise permitted by the Contracting Officer. Care shall be exercised to prevent displacement of soil or seed or other damage to the seeded area during the mulching operations. Mulch shall be uniformly spread by hand or by approved mechanical spreaders or blowers which will provide an acceptable application. An acceptable application will be that which will allow some sunlight to penetrate and air to circulate but also partially shade the ground, reduce erosion, and conserve soil moisture. 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 Contracting Officer. Where the binding material is not applied directly with the mulch it shall be applied immediately following the mulch application. During the application of binding material, adequate precautions shall be taken to prevent damage to vehicles, structures, guardrails, and devices. Areas where seeding and mulching have been performed shall be maintained in a satisfactory condition until final acceptance of the project. Maintenance shall include mowing at the location and times directed by the Contracting Officer. Areas of damage or failure due to any cause shall be corrected by being repaired or by being completely redone as may be directed by the Contracting Officer. Excelsior matting shall be installed on all seeded slopes greater than 3:1 (h:v). Install the matting per the manufacturer's printed instructions.
