NARRATIVE AND SITE IDA T A The project proposes to construct an 11,500 sf+ commercial building with various outdoor entertainment amenities to include a miniature goff course. an elevated ropes course and a zip -fine feature. Utilities; stormwater management, landscaping and lighting improvements will also be provided to serve the development. The project site is located along the west side of NC 12 at its intersection with Atlantic Drive (SR 1247), in the village of Rodanthe, Kinnakeet Township, Dare County, North Carolina. The property is composed of a single parcel totaling 2.1 acres. The site's topography gently slopes from east to west from NC 12 to the western shoreline with the Pamlico Sound. Elevations range from just over 4 ft mil in the south east corner to less than 0.0 ft msi along the sound shoreline. The property was formerly developed with a motel that has since been demolished- Besides remnant areas of gravel, asphalt and utilities, the parcel is currently vacant. Surrounding land use is primarily commercial. Site Soils are composed of. CoB: Corolla Fine Sand: Described as being nearly level, moderately well drained soils with rapid permeability. On -site soils investigation found high permeability rates of 22.a inlhr and seasonal high water table conditions that fluctuate from depths of 1.25 - 2.3 feet below the surface across the site.

THIS PLAN REPRESENTS MINIMUM SEDIMENTATION AND EROSION CONTROL MEASURES. ADDITIONAL MEASURES AND DEVICES MAY BE REQUIRED AS CONSTRUCTION PROCEED11 S ROLLED EROSION CONTROL MATTING SPECIFICATIONS: All areas identifed on these plans as requiring an erosion control matting shall be lined with a protective covering to minimize erosion and protect seed until permanent vegetation is established. Covering shall be composed of a bio or photo degradable material to minimize long term environmental impacts. Mulching with straw or other organic materials can be utilized only when it will not impede the establishment of permanent vegetation. Mulches must be properly anchored which may be difficult in some environments. An example is straw mulch with jute netting stapled or pinned in place. Pre -manufactured rolled erosion control products (RECP) are highly recommended for this application. RECP's shall be installed according to manufacturer specifications for channel linings. An example is a woven straw or wooden fiber Excelsior matting.

Construct & maintain all erosion & sedimentation control practices & measures in accordance with the approved sedimentation control pion and construction schedule. 2. Remove good topsoil from areas to be graded and filled, and preserve it for use in finishing the grading of all critical areas. 3. Scarify areas to be topsoiled to a minimum depth of 2 inches before placing topsoil. 4. Clear & grub areas to be filled to remove trees, vegetation, roots, or other objectionable material that would affect the planned stability of fill. 5. Ensure that fill material is free of brush, rubbish, rocks, logs, stumps, building debris, and other materials inappropriate for constructing stable fills. 6. Place all fill in layers not to exceed 9 inches in thickness, and compact the layers as required to reduce erosion, slippage, settlement, or other related problems. 7. Do not incorporate frozen material or soft, mucky, or highly compressible materials into fill slopes. 8. Da not place fill on a frozen foundation, due to possible subsidence and slippage. 9. Keep diversions and other water conveyance measures free of sediment during all phases of development. 10. Handle seeps or springs encountered during construction in accordance with approved methods 11. Following completion of any phose of grading, provide a groundcover (temporary or permanent' on ail exposed slopes within 14 calendar days, or 7 calendar days in critical areas identifieIfv d on the plan; and, a permanent groundcaver for all disturbed areas within 15 working days or 90 calendar days (whichever is shorter) following completion of construction or development. 12. Provide adequate protection from erosion for all topsoil stockpiles, borrow areas, and spoil areas. MAINTENANCE Periodically check all graded areas & the supporting erosion & sedimentation control practices, especially after heavy rainfoils. Promptly remove all sediment from diversions and other water--disposoi practices. If washouts or breaks occur, repair them Immediately. Prompt maintenance of small. -eroded areas before they become significant gullies is an essential part of an effective erosion & sedimentation control plan. 0 rol SAFETY RAILING TO BE ATTACHED SECURELY TO BULKHEAD (MEET A-D.A.

These areas must be seeded or planted within 15 working days or 90 calendar days after final grade is reached, unless temporary stabilization is applied - PERMANENT SEEDING SPECIFICATIONS Seeding Recommendations for Summer SEEDING DATES - April to July SEEDING MIXTURE Species Rate Common bermudagrass 10/1,000 sf (sprigs) 1-2 Ib/1,000 sf (seed) SOD (See Sodding Notes) Seeding Recommendations for Early Fall through Early Spring SEEDING DATES - August to March (early fall and spring recommended) Species Rate Kentucky 31 Tail Fescue 6 !b/1,000 sf (broadcast seed) SEEDING NOTES- 1. Sprig or sod. Moisture is essential during initial establishment. Sod must be kept watered for 2-3weeks, but can be planted earlier or later than sprigs. Soil Amendments - it is highly recommended that soils be tested and cirnended as found necessary. If a sois are not tested foliow these recommendations: Apply 3,000 lb/ ocre of ground agricultural limestone and 500 lb/acre of 10-10-10 starter fertilizer, or 50 Ib/ocre nitrogen from turf -type slow -release fertilizer. Add 25-50 lb/acre nitrogen at 2-3 week intervals through midsummer. Sprigging - Plant sprigs in furrows with a tractor -drawn transplanter, or broadcast by hand- (Not recommended for Tall Fescue) Furrows should be 4-6 inches deep and 2 feet apart. Place sprigs about 2 ft. apart ir. a row with one end at or above ground level. Broadcast at rates shown above, and press sprigs into the top 1/2-2 inches of soil with a disk set straight so that sprigs are not brought back toward the surface. Mulch- Do not mulch Bermuda Grass. For Tall Fescce seed, apply 4,000-Ib/acre straw, Anchor straw by tacking with asphalt, netting, or a mulch -anchoring tool. A disk with blades set nearly straight con be used as a mulch -anchoring tool. Maintenance - Water as needed. Mow bermudo to 3/4 to 1-inch height and tall fescue to 2.5 -- 3.5 inch height. Topdress bermudo with 40 lb/acre nitrogen in April, 50 lb in May, 50 lb in June, 50 lb in July, and 25 lb in August. Top dress tail fescue in mid September,again in November and February with turf -grade 3-1-2 or 4-1-2 ratio turf -grade fertilizer. Fertilize with 1 lb of actual nitrogen per 1,000 sf. Do not fertilze tali fescue between Mid March and Early Septr-tuber.

SODDING SPECIFICATIONS Sod Quality -Sod should be machine cut at a uniform depth of 1/2-2 inches -Sod should not have been cut in excessively wet or dry weather. -Sections of sod should be standard size as determined by the supplier, uniform, and untorn. -Sections of sad should be strong enough to support their own weight and retain their size and shape when lifted by one end. -Harvest, delivery, and installation of sod should take place within a period of 36 hours. Soil Amendments - Apply lime and fertilizer according to soil tests or apply 75 lb/1,000 sf of pulverized agricultural limestone and 1,000 !b/ocre 10-10-10 fertilizer in the fall, or 5-10--10 in spring - FOR CENTIPEDE GRASS ONLY -- Apply J ib or nitrogen per 1I,000 s,f. Prior to taying sod, clear the soil surface of trash, debris, roots, branches, stones, and clods larger than 2 inches in diameter. Fill or level low spots in order to avoid standing water. Rake or harrow the site to achieve a smooth and level final grade. Complete soil preparation by rolling or cultipacking to firm soil. Sod Installation- 1. Moistening the sod after it is unrolled helps maintain viability, Store in shade during installation. 2. Rake the soil surface to break the crust just before laying sod. During the summer, lightly irrigate the soil, immediately before laying sod to cool the soil and reduce root burning & dieback. 3. Do not sod on grove, frozen soils, or soils that have been treated recently with steriiants or herbicides. 4. Lay the first row of sod in a straight line with subsequent rows placed parallel to and butting tightly against each other, Stagger strips in a brick -like pattern. Be sure that the sod is not stretched or overlapped and that all joints are butted tightly to prevent voids. Use a knife or sharp spade to trim and fit irregular shaped areas. 5. Install strips of sod with their longest dimension, perpindicuior to the slope. On slopes of 3:1 or greater, or wherever erosion may be a problem, secure sod with pegs or staples. 6. As sodding of clearly defined areas is completed, roll sod to provide good contact between roots and soil. 7. After rolling, irrigate until the soil is wet 4 inches below the sod, S. Keep sodded areas moist to a depth of 4 inches until the grass takes root. This can be determined by tugging on the sod. 9. Mowing should not be attempted until the sod is firmly rooted, usually 2-3 weeks. Sodded Waterways 1. Prepare soil as described above. 2. Lay sod strips perpindicular to the direction of flow, with the lateral joints staggered in a brick -like pattern. Butt edges tightly together. Maintenance - After the first week, water as necessary to maintain adequate moisture in the root zone & prevent dormancy of the sod. Do not remove more than one-third of the shoot in any one mowing. Grass height should be maintained between 2-3 inches unless otherwise specified. After first growing season, established sod requires fertilization, and may also require lime.
