Box 1327 Nags Head, NC 27959 i Subject: Stormwater Review SW7071013 Belhaven Fish & Oyster Beaufort County Dear Mr. Dixon: This office received a Coastal Stormwater permit application and plans for the subject project on October 18, 2007. A preliminary review of the project indicates that before a State Stormwater permit can be issued the following additional information is needed. 1 1. Our search of the North Carolina Department of the Secretary of State website didn't find any results for Dixon & Hoyle Partnership registration. Please advise if applicant name is correct or provide the registration information; i 2. The Stormwater Calculations and Narrative shows required volume for Infiltration basin of 115 c.f., while the supplement calls for 106 c.f.. Please revise the Supplement for Infiltration Basin 2 to reflect this change; V/ 3. Revise the vegetated filter and level spreader width to at! least 13 feet, to comply with the minimum level / spreader length; V 4. As proposed, the D.I. #1 will be used as an off-line bypass, however by setting the top elevation of said D.I. to 4.5' and having the bottom elevation of Infiltration basin #1 at 4.3', the effective storage will be only 0.2' before the stormwater start to bypass the system. Revise the top elevation of D.I. #1; i 5. Ideally, the sides of an open infiltration basin should be vegetated, but could be stabilized with pretty much any suitable material as long as it didn't create a nuisance condition and prevented erosion of the slopes into the basin. As proposed, 4" of #57 stone over filter fabric on the side slopes of an infiltration basin would be acceptable, however the bottom should be left with a 4" sand layer, unvegetated with no rock or gravel or /filter fabric. Please revise; 6. Provide two sets of signed and sealed calculations, plan shleets and documents. The above requested information must be received in this office prior to November 2, 2007 or your application will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the application fee. If you need additional time to submit the required information, please mail or fax your request for time extension to this office at the Letterhead address. You should also be aware that the Stont water Rules require that the permit be issued prior to any development activity. Construction without a permit is a violation of 15A NCAC 2H.1000 and North Carolina General Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.

J:\WPDATA\WQS\State SW-TMA\SW Application Review Checklist revised (Updated 6/18107) PROJECT TYPES AND A. Low Density: Supplement SWU-104 or SWU-105 Applicability: ■ Low density projects may not result in built -upon surfaces in excess of 25% or 30%, depending on the classification of the receiving stream. For calculating density with wetlands, see guidance memo (reference document and location). ■ In low density projects, stormwater is conveyed primarily via sheet flow and swales with limited piping for under road conveyance. Curb outlet systems may also be used in a low density project. ■ No area of the project may be configured such that it 'constitutes a pocket of high density. In other words, if development is concentrated such that the undeveloped land does not significantly impact treatment of the stormwater runoff from the developed or impervious surfaces, the low density option may not be applied to the overall project. • Low density projects must maintain a 30 foot wide vegetative buffer. That is, any impervious surfaces must be at least 30 feet from surface waters, measured horizontally from the structure to the mean high water line of the surface water. • All swales and related vegetated slopes must be 3:1 (horizontal to vertical) or flatter. • Regulatory References: NCAC Title 15A, 02H.1005,IO2H.1008(g). SWU-104 is required for low density projects for which lot subdivision and selling is intended. All sections of the supplement should be completed including the built -upon area per lot calculation. Deed restrictions are required. SWU-105 is required for low density projects in which curb and gutters are incorporated. All sections should be completed including swale design, Table 11. Supporting calculations should also be supplied. The maintenance agreement contained within the supplement must be signed and notarized. I 4 Applicability: • General permits may be issued for certain groups of (1) construction of single family residences (SWG( (2) bulkheads and boat ramps (SWG02), (3) clearing and grading (SWG03), and (4) linear utility projects (SWG04). • For these types of projects, a Notice of Intent should Certificate of Coverage will be issued covering the a ■ Regulatory Reference: NCAC Title 15A, 02H.1013.

The most current policyOctober 5 2006 re ardln the amount of wetlands that can be included In the site area Is ictaed by whichever of the following two calculation methods yields the least amount of site area: Method 1: Calculate the acreage of the wetlands.Divide the wetland acreage by the total site acreage. If the result is 25% or less, thenithe total project area Is the total site acreage. If the result is more than 25%, then calculate the amount of wetland to Include such that no more than 25% of the site area acreage consists of wetlands in this manner: subtract the entire wetlands' area from the site area to get the uplands area, then divide the uplands area by 0.75. Method 2: Calculate the area of a 100 foot wide strip of wetlands measured from the uplands area into the wetland. Compare the two numbers, and choose the one that EXAMPLE A: Total site area = 55 acres Total wetland area = 15 acres ►100' wide strip of wetland area = 5 acres Method 1: 15 acres wetlands / 55 acres 55 acres site —15 acres wetla Project area for calculating de Method 2: 55 — 15 = 40 Project area for calculating de Since 45 < 53.33, use area derived via Method EXAMPLE B: Total site area = 55 acres Total wetland area = 10 acres 0-100' wide strip of wetland area = 5 acres Method 1: 10 / 55 = 18.2% (<25%) Project area for calculating den Method 2: 55 — 10 = 45 acres Project area for calculating der Since 50 < 55, use area derived via Method 2 EXAMPLE C Total Site Area = 55 acres Total Wetland Area = 40 acres Do- 100' strip of wetland area = 15 acres Method 1: 40 / 55 = 73% (>25%) 55 — 40 = 15 acres Project area for calculating the smallest project area. 27.3% (> 25%) = 40 acres uplands = 40 / .75 = 53.33 acres = 40 + 5 = 45 acres to calculate the allowable density. = 55 acres y = 45 + 5 = 50 acres calculate the allowable density. = 15 / .75 = 20 acres Method 2: 55 — 40 = 15 1 Project area for calculating density = 15 + 15 = 30 acres Since 20 < 30, use area derived via Method 1 for calculating the allowable density. ®The 1 00'wetland strip is measured from the 401/404 line waterward (into the wetlands) of the project for a distance of 100', or to the mean high water, (MHW) line or to the property line, whichever comes first. No credit for wetlands located outside of the property line or beyond the MHW line can be given. By definition, the project area includes only that area above the MHW Line. I S:\WQS\STORMWATER\FORMS\WETLANDS POLICY AND EXAMPLE CALCS Last updated 10/05/2006 ,egiltto?r•� C7 •�cSv11J!I ` • Stormwater Management Plan Narrative . Q SEA" Belhaven Fish & Oyster Q;y5158 September 28, 2007 General The following narrative will detail the stonnwater management plan for the proposed redevelopment of the Belhaven Fish & Oyster site in Belhaven, NC. Belhaven Fish & Oyster is a proposed multifamily residential housing development to be located on 0.88 acres of previously developed land located on the south side of Water Street immediately south of the intersection of Pamlico Street and Water Street. The site's improvements have been razed and the site is currently being utilized for storage of boats, construction equipment, and shipping containers. Significant remnants of previous development remain buried shallow (2' or less) beneath the current ground surface. This application proposes to redevelop this property as a small (single building with 10 units) multifamily residential housing development. As per state regulations, a high density permit is being pursued. i I The proposed stormwater management method will consist of two infiltration basins with enough storage capacity to hold the runoff generated by a 1.19 inch rainfall event. The following narrative, application and calculations will demonstrate the parameters of this design which will illustrate an effective stormwater management system in full compliance with all state regulations. Summary of Existing Conditions The subject parcel is located on the south side of Water Street immediately south of the intersection of Pamlico Street and Water Street and consists of 0.88 acres of previously developed land. The site's improvements have been razed and the site is currently being utilized for storage of boats, construction equipment, and shipping containers. Significant remnants of previous development and other debris remain buried shallow (2' or less) beneath the current ground surface. Additionally, the existing site is currently covered with approximately 3,250 sf of impervious cover compacted gravel) near the Water Street Frontage. There are no discernable existing stormwater controls and the bulk of stormwater runs off the site to the perimeter property lines without treatment from BMP's. Summary of Proposed Conditions i The Belhaven Fish & Oyster project will consist of demolition of remaining above ground improvements, removal of subgrade improvements and debris within the development footprint, and redevelopment with a single multifamily dwelling structure with associated parking and utility infrastructure. Ass part of the new development, stormwater BMPs in the form of dry infiltration basins are proposed to provide infiltration for runoff from collected areas within the site. Complete storage and disposal of the l" rainfall event will be' provided within the infiltration basins with the collection system providing an off-line bypass and 30' vegetated filter at the system outfall. OCT 1 8 2007 DWQ- ARQ Site Summary Table Total Impervious Coverage (above grade) Stormwater Measures Existing Conditions 3,250 sf of coverage None Proposed Conditions 17,524 sf of coverage Complete storage and infiltration of 1 inch rainfall event Stormwater Collection, Treatment, Storage and Disposal Collection The stormwater runoff will be collected and directed via site grading, curb and gutter, and drop inlets which convey runoff to the infiltration basins via storm sewer. Treatment The basins will offer several methods of stormwater runoff treatment prior to release. Runoff from paved areas will sheet flow to drop inlets and be directed to the wet detention basin via a storm sewer system. Large particulates and debris will accumulate at the drop inlet grates. Runoff will discharge from the storm sewer system via upwelling within drop inlets placed within each basin. These drop inlets are provided with sumps and this upwelling will also serve to trap large debris and sediment within the drop inlets (which will need to be cleaned periodically as part of the maintenance of the system). The exposed basin bottoms will be grassed according to the general seeding specifications and maintained according to the operation and maintenance plan and the basin bottom under the building will be topped with a layer of clean sand. The runoff will undergo filtration of fine particulates and pollutants by the vegetation within the basin bottoms and side slopes as well as filtration by the surface sand within the basins. If the weather yields precipitation that exceeds the storage capability of the basin system then the accumulated runoff will overflow the storm sewer via upwelling within a drop inlet located on the west side of the propertylwhich discharges to a 30' vegetated filter. A secondary treatment method is also available when the stormwater (runoff infiltrates into the subsurface. When the water passes through the void spaces between the particles of soil material particulates and pollutants that have a particle or grain size larger than the void size will be filtered out. In addition some pollutants will adsorb to the surface of the soil particles. The benefit of this adsorption will prevent the pollutants from reaching the water table and in some nutrient and microbe rich areas existing within the subsurface the pollutants will be consumed as food and undergo a natural biodegradation. Sty This infiltration basin system will offer a portion of storage above the ground surface and a portion of storage within the void spaces available in the subsurface. Within Drainage Area I, the runoff generated by a I inch storm will require 1,337 ft' of storage. The storage available above the ground surface is 1,455 ft3 (equivalent to runoff generated by 1.09 inch storm). Additional storage is available within the subsurface in the two (2) feet of separation between the basin bottom and the seasonal high water table and the additional separation between the submerged basin side -slopes and the seasonal high water table. A more detailed discussion of subsurface storage volume can be found within the soils section of this narrative. I Within Drainage Area 2, the runoff generated by a 1 inch storm will require 115 ft} of storage. The storage available above the ground surface is 275 ft' (equivalent to runoff generated by 2.4 inch storm). Additional storage is available within the subsurface in the two (2) feet of separation between the basin bottom and the seasonal high water table and the additional separation between the submerged basin side -slopes and the seasonal high water table. A more detailed discussion of subsurface storage volume can be fo�lund within the soils section of this narrative. Disposal As discussed in previous sections the majority of stormwater runoff entering this management system will be infiltrated, therefore infiltration will be the primary source of disposal. The system has been designed with storage so that this site will have the capability to handle in excess of a 1 inch storm event. At such time that the capacity were to be exceeded the system will then overflow into the adjacent vegetated filter via upwelling within a drop inlet structure. Soils II Quible & Associates performed on -site soil borings to verify soil type and determine elevation of mean high groundwater. Information collected on site indicates that the soils found throughout this site are composed of a mixture of sands, silts, clays, and debris which have been deposited and modified significantly over time through the urban development of this area. These findings generally correlate with the description mapped and discussed in the United States Department of Agriculture, Soil Conservation Service,) Soil Survey of Currituck County, North Carolina, which map the soil for this site as follows: Ur - Urban land, Urban areas which have generally been greatly alte�ied by cutting, filling, grading and shaping Infiltration rates can vary wildly within these soils. A significant layer of debris was encountered approximately 2' below the ground surface at all boring locations within this site which prevented deeper exploration. Pursuant to this finding„ Quible & Associates has referred to exploratory information and experience on a neighboring site, Day Beacon #9 (NCDENR Stormwater Permit #SW7051 110). The Day Beacon #9 site is located approximately 150' to the east / southeast of the subject site and has a similar site history with similar site layout, topography, and geography. At the Day Beacon #9 site, Quible & Associates performed multiple soils borings and slug tests to verify minimum adequacy of the soils with respect to infiltration. Similar to the project site, there were locations where borings were not able to penetrate due to subsurface debris, but enough borings were able to be made to gather the information to produce a design. Soils boring logs from that site are included in the appendix of this narrative. As with the Day Beacon #9 site, this project proposes to remove all in -situ soils and debris from within the infiltration basin footprint down to an elevation of Off (and deeper if a visual inspection by the engineer dictates that it be excavated further) with backfill of the excavation utilizing a porous sand. This construction process was implemented on the Day Beacon #9 site and the infiltration basins are in place and functioning as anticipated. In order to provide a conservative result, a minimal infiltration rate of 0.52 inches per hour was assigned to the backfilled soil for the purposes of calculating drawdown times. It is anticipated that the actual infiltration rate will be much higher. i As mentioned in the storage section of this narrative a more detailed description of the method of determining the subsurface storage volume available as a function of the soils would be discussed in this section. The following determination of the volume available in the subsurface is based on the definition of Porosity: The ratio of volume of void spaces in a rock or sediment to the total volume of the rock or sediment. Porosity = q = Volume of pore space x 100 Vohmteof ba'lksolid Table 10.3.

This value should be considered conservative. A distance of two vertical feet is to be maintained between the infiltration basin bottom and the seasonal high water table elevation. Soil borings and other infonnation (as discussed above) indicate a conservative seasonal li igh water table of approximately 2.0 feet MSL. The proposed infiltration basin bottom elevation was designed at an elevation of 4.3 MSL, providing for a vertical separation of 2.3 feet. Within this separation distance exists a volume of soil containing a minimum of approximately 20% void space. This void space will become filled with water and provides for an additional volume for stonnwater runoff storage. Calculations A set of sample calculations can be found within the appendix portion of this narrative. Conclusions The proposed stormwater management plan for this site will handle tin excess of the 1.0 inches of stormwater runoff generated by all surfaces, pervious and impervious located within thIe drainage area by incorporating two infiltration basins. The proposed system will offer preliminary, primary and secondary methods of treatment as well as an alternate method of disposal should the capacity be exceeded. The construction plans produce infiltration basins with infiltration rates approximately 0.52 inches per hour, conditions ideal for an infiltration basin system. This proposed design will more than adequately serve the stormwater management requirements of this site. I David M.

Marchello. PLS. This letter and information package serve as a report summarylof groundwater data collected on December 6, 2005 at the Daybeacon #9 Site in Belhaven, North Carolina (Figure 1). Groundwater data was gathered from two temporary monitoring wells installed on December 6, 2005 for the purpose of discerning the infiltration rates expected in the location of the proposed infiltration basin depicted on the enclosed copy of the site plan (Figure 2). One temporary well SW -IC (third attempt) was installed in the location depicted on the enclosed Figure 2 to a depth of nine feet below ground surface. A copy of Aquifer Protection Section Form GW-1 b has been have been included as Appendix A. An additional temporary monitoring well SW-213 (second attempt) was installed in the location depicted on the enclosed Figure 2 to a depth of eight and a half feet below ground surface. A copy of Aquifer Protection Section Form GW-lb has been included as Appendix A. Based on the lithology recorded during the installation of the temporary monitoring wells, an impermeable surface of compacted oyster shells, gravels and asphalt was discovered in five separate borings in the vicinity of the proposed stormwater basin. The layer of oyster shells and fill was immediately underlain by silts and clays. This layer of compacted oyster shells, asphalt and fill material was recorded at a consistent depth of one to two feet below the ground surface. Detailed boring logs and stratigraphy are presented in Appendix B. j I Agtesoly® software was used to calculate hydraulic conductivitylat the site. In -Situ@ mini -Troll data loggers, calibrated to manufacturers specifications, were inserted in the test wells (SW -IC and SW-213) and subsequently a slug of water was removed from each well using a 36" disposable polyethylene bailer. A depth to water measurement was recorded at predetermined intervals for the duration of each test. The data from each test was downloaded into the Aqtesolv® software land used to calculate hydraulic conductivity (K) based on the Bouwer-Rice Method for unconfined aquifers. The Aqtesolv@ software automatically matches a best fit line base d on the total number of points for the entire test. However, the initial portion of the curve (displacement vs. time) is actually the water from the filter pack rushing into the well. Therefore, a visual match solution is preferred to account for the initial instantaneous recharge from the surrounding sand filter pack. Based on data collected from the slug tests conducted on September 6, 2005 and analyzed using the unconfined Bouwer-Rice Method, the hydraulic conductivity at the site ranges from 5.471E `ft/min in SW-1C to 3.451E 3ft/min in SW-2B. This translates to a range of 0.39 in/hr in SW -IC to 2.48 in/hr in SW-2B. Slug test data for each test has been included as Appendix C. It is recommended that the impermeable surfaces encountered in each of the borings be excavated and removed from the site. Please note, these impermeable surfaces or horizons were reportedly removed during site demolition activities. However, Dixon -Hoyle switched contractors prior to the completion of the demolition and subsequent filling of the site. Therefore, it is assumed that the old asphalt entrance and sub -grade is still intact at the site.
