ADDITIONAL CONDITIONS Permit #32-88 Page 2 are placed closer than a line sixty times the annual erosion rate from the most seaward line of stable natural vegetation, all pilings shall have a tip penetration of at least five feet below mean sea level or sixteen feet below average original grade, whichever is least. (5) All foundations shall be adequately designed to be stable during applicable fluctuations in ground elevation and wave forces during a 100 year storm. Cantilevered decks and walkways shall meet this standard or shall be designed to break-away without structural damage to the main structures. (6) All pilings shall be appropriately treated to resist decay, insects and corrosion. (7) The lowest portion of the structural member of the lowest floow (excluding the pilings or columns) shall be elevated above the 100 year storm elevation plus wave height addition. (8) All exposed structural connections shall be adequately rustproofed or enclosed. (9) All utility systems shall be located and constructed so as to minimize or eliminate storm damage. (10) All walls below 100 year base flood level shall be designed and installed to: (A) allow storm waters to rise and flow freely under the structure. (B) not permit the breakaway walls themselves to become water-borne debris, and . (C) not cause the accumulation of water-borne debris. Break-away walls shall be intended to collapse under stress without jeopardizing the structural support of the structure. (11) No impermeable (such as asphalt or cement) surfaces shall be allowed over any functional part of a complete septic tank system. (12) The dune crossovers will be exclusively for pedestrian use, less than six feet in width and raised on pilings of five feet or less depth so that wherever possible, only the pilings touch the frontal dune. (13) Any areas of dune vegetation that are disturbed will be revegetated as soon feasible. (14) No work shall begin until the oceanfront setback location can be established. When the permittee is ready to begin construction, he shall arrange a meeting with the appropriate DCM Field Representative at the site to determine the vegetation line to set the oceanfront setback. This determination shall replace the one done at the time the permit was processed and approved and construction must begin within a period of 60, days from the date of that meeting (otherwise a remeasurement is required). Ships Watch, Inc. ADDITIONAL CONDITIONS Permit #32-88 Page 3 (15) All pumps and structures (other than necessary buried pipes) associated with the oceanfront wells shall be located outside the setback area. The permittee must, at all times, retain sites for 100% replacement of the ocean- front well fields. The oceanfront pipes located within the setback area may not be protected from erosion by shoreline stabilization. (16) The disturbed areas will be properly graded and provided a ground cover sufficient to restrain erosion within thirty (30) days or project completion. NOTE: In signing this permit, the applicant acknowledges the risks associated with development in the Ocean Hazard AEC and the limited suitability of this area for permanent structures. By granting permits, the Coastal Resources Commission does not guarantee the safety of the development and assumes no liability for future damage to the development. NOTE: The Division of Environmental Management issued Section 401 Water Quality Certification No. 2070 for this project for isolated wetland fill approved by a Corps of Engineers Nationwide permit. NOTE: The permittee is reminded that plans and specifications for the water system must be approved by the Potable Water Supply Branch, Division of Health Services prior to initiation of construction. NOTE: Retention and detention areas for stormwater runoff using man-made or natural swa es, either vege ated or unvegetated, can create mosquito breeding sites capable of producing large numbers of very pestiferous mosquitoes. Those who construct or use such areas should be aware of this problem and of their responsibility to control these mosquitoes, which readily migrate to other places also. Mosquito production in these areas can be reduced by designs 'which allow water to stand for no more than three days. Chemicals can also be used judiciously to control mosquito larvae. A good system of regular inspections (at least weekly during the warm months) can provide the information needed to manage these pests properly. The staff of the Vector Control Branch, (919) 733-6407, is available to inspect such areas and offer advice on how best to control mosquitoes there. DIVISION OF ENVIRONMENTAL MANAGEMENT Water Quality:Section February 1, 1988 M E M O R A N D U M TO: Jo n Parker FROM: ill Mills SUBJECT: Application for CAMA Permit - Revised Shipswatch Currituck County The Subject revised application has been reviewed for water quality impacts and the following comments are offered: a. Concerns regarding the suitability of the site and available setbacks for sewage disposal at Shipswatch have been resolved. The site is suitable for the type and size of sewage disposal now proposed based upon revised layout and other supporting information received January 27, 1988. BM/dkb cc: Jim Mulligan MEMORANDUM 11A NI 19 1988 TO: Bill Mills 1! _ ;cC1101`' FROM: John Park SUBJECT: Ships Watch, Inc. DATE: January 19, 1988 This office has been informed by Bill Gilbert, who represents the applicant and Al Hodge of your Division, that materials have been submitted that are sufficiently adequate to allow DEM to submit a final comment for the CAMA review. I advised both gentlemen that I would review the file and initiate a request to your office for final comment. I have requested, for the CAMA file, new plats to show any site plan changes that may have taken place. Assuming the new materials are adequate for DEM to inform this office that the waste load in the CAMA application can be treated by the proposed method on the proposed site, we would appreciate your final comment at the earliest possible time, preferably during the week of the 18th. JP/aw DIVISION OF ENVIRONMENTAL MANAGEMENT Water Quality Section December 8, 1987 M E M O R A N D U M TO: John Parker FROM: Bill Mills SUBJECT: Application for CAMA Permit Shipswatch, Inc. Currituck County As you have requested, we have reviewed the information which has been submitted on the sewage disposal system for the subject project to determine whether the site will be suitable for the type and size of sewage treatment system proposed and will accommodate the wastewater expected to be generated from the development which is proposed in the CAMA application. Evaluation earlier this year by our regional office indicated that the disposal by rotary distributors would be acceptable for this site. Final plans and specifications, application forms, and application fees were received for sewage disposal at this site on November 9, 1987. By letter dated November 19, the application was acknowledged and the applicant advised that certain information would have to be submitted before any further review of the application could be made. The applicant was advised to respond to the requested information before January 19, 1988 to prevent the application from being returned as incomplete. Several items related to the suitability of the site to accommodate the 70,000 gpd of wastewater expected to be generated from the units represented in the CAMA application. Items related to the site which must be resolved are as follows: 1. The proposed rotary distributors as located do not conform to the separation of 100 feet from property lines that is required by 2H .0200. 2. The 100-year flood level with respect to the treatment and disposal facilities must be identified. 3. The applicant has also been asked to describe the type of development on properties adjacent to the treatment and disposal facilities. Until these items have been resolved we cannot advise that the site is suitable for the type, location, and size facilities described in the CAMA application.

SHIPS WATCH, INC. BIO REPORT PAGE 2 SITE DESCRIPTION Submitted by: George H. Wood Date: May 19, 1987 The applicant owns a 70.8 acre tract on the Currituck Outer Banks just south of Whalehead Subdivision which extend$ from the Atlantic Ocean to the Sound. The property rises from the Atlantic Ocean to a primary dune ridge 15 to 20 feet high. -The erosion rate in this area was adjusted by the Coastal Resources Commission in November of 1986 to extend the seven foot rate along the entire development making the setback for single family structures 210 feet from the first line of stable natural vegetation. Extending towards Ocean Trail are 51.5 acres of rolling sandy property which will be subdivided into 101 single family lots, primary well field, two outdoor tennns courts, recreation center, four retention ponds,.roads and parking areas. Reserved well fields are shown to be located along the crest of the primary dune ridge. The sound side of Ocean Trail is 19.3 acres of land. Approximately 5.8 acres have been identified as wooded swamp or coastal wetlands and are delineated by the "404 line" which was verified 1/15/87. A small isolated wetland (.37 acre) was authorized to be filled by Nationwide permit from the Corps and this work has been accomplished. All the development on the sound side except for a 6 foot wide pier extending 250 feet into the sound with a 500 square foot "T" head, will be landward of the "404" line. Proposed on this side of the development are: - 8 apartments to house employees. - A restaurant. - Convenience store. - Sales office. - Seven retail buildings. - A 70,000 G.P.D. waste treatment facility. Parking and drives. ANTICIPATED IMPACTS The proposed development will result in the disturbance of 40 acres of sandy highground during the construction of the subdivision. The ocean front single family lots are platted 210 feet from the first line of stable natural vegetation. No wetlands are proposed to be excavated or filled. The review of this proposal should assess the availability of potable water to supply the development and the adequacy of the 70,000 G.P.D. waste treatment facility. The need for increased municipal service should be addressed by the county. CAMA REVIEW The project site is classified as transition in the Currituck County LUP. A copy of this proposal is being forwarded to the county.

The applicant is seeking a CAMA Permit for a proposed planned unit development (P.U.D.) located on the Currituck County Outer Banks approximately five (5) miles south of Corolla, North Carolina. The Ships Watch - Currituck P.U.D. consists of 70.8 acres which extends from the Atlantic Ocean to the Currituck Sound. Ocean Trail bisects the property leaving 51.5 acres on the east side of the road and 19.3 acres on the west side. The enclosed plat (sheet 2 of 4) shows the proposed development including a chart with the break down of land use areas. The east side of Ocean Trail will be developed as single family lots with a recreation center located by the entrance while the west side of the road will be developed as a commercial site (retail, restaurant, office, etc.) including a wastewater treatment plant and disposal area that will serve the entire development. The ocean front erosion rate in the development area is 7 ft./yr. Therefore, the setback for the single family homes will be 210 ft. (30 x erosion rate). The only construction within the 210 ft. setback will be the secondary wellfields and elevated boardwalks as shown on the enclosed plat (sheet 2 of 4). The approximate shoreline and marshline adjacent to the Currituck Sound (classified as SC waters) is shown on the plat. The only development in the Area of Environmental Concern will be an elevated boardwalk (less than 6' wide) across the wetlands which will extend approximately 250 ft. into the sound and have an open deck, at the end, less than 500 square feet in size. The closest commercial buindings will be 650' to 800' away from the Currituck Sound. A. U.S. Army Corps of Engineers Jurisdictional Areas: In conjunction with Alison Arnold of the U.S. Army Corps of Engineers we have located the 404 jurisdictional area. The boundary of this area is shown on the enclosed plat. The wetlands are adjacent to the Currituck Sound and extend 450 ft. to 900 ft. east of the shoreline. The 404 line was verfied on-site 12/11/86. Enclosed is a copy of the verification letter dated 1/5/87. Kitty Dunes Professional Center 41/Q Milepost - 158 Bypass P.O. Box 1334, Kill Devil Hills, N.C. 27948 I? The only structure to be constructed over any wetlands is an elevated walkway less than 6 ft. wide which will extend into the sound and end with a less than 500 sq. ft. open platform. A profile and plan view of the pier is shown on the detail sheet (page 4 of 4). ' Enclosed is a copy of the Nationwide Permit No. 26, dated 4/22/87, which was received from the U.S. Army Corp of Engineers. In conjunction with this permit, a ' certification pursuant to Section 401 of the Federal Clean Water Act (Certification No. 2070) was received from the North Carolina Department of Natural Resources and Community Development, Division of Environmental Management. A copy of this certification is also enclosed. ' B. Sedimentation & Erosion Control: A sedimentation and erosion control plan has been ' filed and approved by the North Carolina Department of Natural Resources and Community Development, Division of Land Resources, Land Quality Section. A copy of the approved sedimentation and erosion control plan is enclosed (sheet 3 of 4). Also enclosed is a copy of the letter of Approval dated 4/7/87. ?1 The existing dune which runs north-south through the commercial area (west side of Ocean Trail) will remain intact with natural vegetation except for two road cuts to provide vehicular access to the westernmost commercial area. These road cuts will be stabilized by bulkheads. The areas designated as "proposed ponds" will be excavated with the total amount of material to be removed consisting of approximately 27,000 cubic yards. The excavated material will be used on-site to build up a road base, to fill the Wastewater Treatment Plant Rotary Distributor areas, to build tip commercial building sites, and to fill any low areas on individual building sites. All disturbed areas will be seeded to prevent erosion. The majority of the project will be constructed at or near existing grade to minimize land disturbing activities. t I D. Stormwater Runoff: This project has been reviewed by William Moore of the North Carolina Department of Natural Resources and Community Development, Division of Environmental Management, Water Quality Section in reference to the recently adopted stormwater regulations. Mr. Moore concluded that this project does not fall under their guidelines, therefore a stormwater management plan is not required by the Water Quality Section. However, we have addressed stormwater runoff from the development. Swales are planned adjacent to proposed roads to intercept any runoff. As water is intercepted by the swales, infiltration will begin immediately in this very permeable soil with infiltration rates of 20 inches per hour and greater. Any runoff which does not infiltrate in the swales will be directed into the proposed ponds which will. act as settling basins as well as detention areas. In the commercial area on the west side of Ocean Trail an overflow swale will be constructed which will direct any overflow from the pond toward the wetlands in the form of overland sheet flow. The wetlands will provide a 500' plus natural vegetative buffer between the development and the Currituck Sound which is designated as SC waters. The larger ponds in the interconnected with the Ocean Trail to provide high water table. Water Supply: residential area will be ponds on the west side of relief in case of an unusually The water requirements for the PUD will be supplied from three separate well fields shown on the enclosed plat (sheet 2 of 4). The primary well field, which will be constructed immediately, runs in a north-south direction and is located approximately 1,300 ft. west of the Atlantic Ocean adjacent to the northern property line. The two secondary well fields are located along the frontal dune within the Area of Environmental Concern. A future raw water line from these secondary ' well fields is shown on the plat and is located westerly of the 210 ft. setback line. On October 1, 1986, David Bissette of the North Carolina Department of Human Resources, Public Water Supply Branch, Environmental Health Section visited the site to investigate the proposed well sites. These sites were approved and the letter of approval, dated October 3, 1986, is enclosed. On March 3, 1987 Well Construction Permit No. 26-0057-WS-0018 was received from the North Carolina Department of Natural Resources and Community Development, Division of Environmental Management. This permit is for the construction of the 4 wells in the primary wellfield, and is enclosed with this letter. On 10/27/87 Mark Bissell, Ken Stuart, and Tim Thornton met with Dave Owens and his staff to discuss this project. In reference to the secondary well field Mr. Owens foresaw no problem with its location within the 210' AEC setback. ' Recommendations from the project hydrogeologist are attached to this application. From USGS information the 100 year flood elevation is below the 10' elevation. Therefore, the reserve well field will be well above ' this level. E. Wastewater Treatment: The wastewater from the development will be collected and treated on- site. A tertiary wastewater treatment package plant is currently being designed which will handle the daily sewage flow. The wastewater will be treated in accordance with the North Carolina Division of Environmental Management Coastal Regulations and the treated effluent will be disposed of by the use of two rotary distributors,or low head sprinkler beds., The proposed location of the wastewater treatment plant and the rotary distributors is on the western side of Ocean Trail on the far northern edge of the property,as shown on the plat. (sheet 2 of 4) Al Hodge from the North Carolina Division of Environmental Management has visited the site and given tentative approval of the site for wastewater disposal. Enclosed is correspondence from Mr. Hodge dated 2/25/87 in reference to the proposed wastewater treatment facility. A hydrogeological report covering wastewater disposal for this project is enclosed. The required number of copies of the supporting data are included, and a copy has been submitted to the Corps of Engineers for concurrent review.

We have retained one copy of the survey for our files. The "Jurisdictional Area" was flagged by Mr. Chris Marsh of Environmental Services, Inc., with guidance from Ms. Alison Arnold of my staff. Ms. Arnold visited the site on October 2, 1986, November 13, 1986, and December 11, 1986. She has verified the accuracy of the placement of the line and that of the survey. The discharge of dredged or fill material within the "Jurisdictional Area" shown on the enclosed survey would require prior Department of the Army approval under Section 404 of the Clean Water Act. In addition, any structures or work below the mean high water mark of Currituck Sound would require prior Department of the Army approval under Section 10 of the Rivers and Harbors Act. To prevent an unintentional violation of Federal law, any land disturbing activities within the "Jurisdictional Area" should be reviewed by this office prior to the start of work. Rules and policies of the Corps of Engineers regulatory program are subject to change, as is the physical nature of the property. Work on the property should not be affected by any such changes if completed within 1 year from the date of this letter. If such work is not completed within 1 year, then you should contact this office for verification of this jurisdictional determination prior to further construction.

Box 1334 Kill Devil Hills, NC 27948 ' RE: Proposed Well Sites Sea Watch Development Currituck County Dear Mr. Gilbert: 1 This letter will acknowledge our October 1 meeting and investigation regarding three proposed well sites on which wells are to be constructed to provide potable water to the Sea Watch Development. ' The proposed primary well field number 1 is located adjacent to Albacore Street approximately 900 feet east of the intersection with Ocean Trail. Reserve well field number 1 is located on the dune line approximately 400 feet south of Albacore ' Street. Reserve well field number 2 is also located on the dune line approxi- mately 750 feet south of reserve well field number 1. The exact locations of the well sites are shown on the attached drawing which is being forwarded to our Plan ' Review Section of the Public Water Supply Branch for reference and identification purposes. The above described sites are adequate in size, and wells located as shown on the drawing can be protected within the required 100-foot radius. No potential sources of pollution are presently located on the sites, and surface water drainage appears satisfactory. We again bring to your attention that no drainage ditches, sewer lines, or other sources of pollution will be allowed within 100 feet of the well site locations. The above described sites are hereby approved by the Division of Health Services, North Carolina Department of Human Resources, as sites on which wells may be constructed in order to provide potable water for the Sea Watch Development, Currituck County, North Carolina. Mr. Bill Gilbert Page 2 October 3, 1986 ' Approval of the water quality will be based on analysis of water from each well which must be performed by a properly certified laboratory. It is also necessary that 24-hour pumping tests be conducted on each well upon completion. Prior to 1 completion of the wells, all collected data must be forwarded to our Plan Review Section for review and approval. 1 In addition to our approval, if the yield of a single well is 70 gallons per minute or greater or if the combined yield of two or more wells is 70 gallons per minute or greater, you must obtain a well construction permit from the Department of Natural Resources and Community Development prior to drilling the wells. If you desire additional information regarding this matter or if this office can be of further service, please do not hesitate to call on us. Sincerely, David W. Bissette Environmental Engineer !

Bissell Associates P. 0. Box 1334 Kill Devil Hills North Carolina 27948 Re: Water Supply Ships Watch Currituck January 25, 1987 Dear Mr. Bissell: J L n i This letter report contains models of possible well configurations, similar to those that we discussed for Ships Watch Currituck (Figure #1, Location Map). It appears that the water table aquifer is thick and homogeneous relative to other locations along the barrier island. The basic design and planning constraints are based primarily on water quality limitations. These water quality limitations are divided into two groups. The first group consists of water quality parameters such as iron, color and hydrogen sulfide concentrations, which vary within the water table aquifer relative to sources of the contaminants. The second group consists of high chloride and correlated high sodium concentrations, which serve as water quality and density boundaries to the water table aquifer. Water quality analysis of the lest well # 4, near the proposed well field (Figure # 2, Site Map), indicates that chloride concentrations are sufficiently low (less than 50 mg/1) to support the development of a 100 gallon per minute supply using three or four wells. The depth to the underlying salt water was not defined in the test wells, which were drilled to 60 feet below land surface. Water samples from various depths, reveal that iron concentrations appear to vary at different depths (Table # 1, Water Quality Characteristics). The water sample collected from 30 to 40 feet below land surface indicated iron concentrations greater than 8 mg/I (test well # 4). Potable supply wells screened either above or below these high concentrations are likely to experience iron deterioration with pumping. Even though samples above and below this zone contained iron concentrations between 0.3 to 1.0 mg/I, the use of sequestriants is not reliable. It is expected that the 250 mg/I isochlore (salt water boundary) is P Mr. Bissell, P.E. January 15, 1987 Pg. 2 at Ieast100 feet below land surface, based on the analysis of deep well transects ' at Kitty Hawk, North Carolina (The Impacts of Wastewater Disposal Practices on the Hydrogeology of the North Carolina, Volume 1, July 1985). Therefore, analyses of several pumping scenareos (Table # 2, Salt Water Intrusion t Model) indicate that upconing of saltwater should not interfere with seasonal use. High chloride concentrations that bound the fresh water aquifer laterally, should not substantially affect seasonal use, if the welt field is located as shown on the site map (Figure # 2, Site Map). ' The location of an additional well behind the dune line as an alternate supply, will help to offset some of the impacts of changed water duality t due to extended pumping. The extended pumping of the primary will induce poorer quality water (specifically high chloride concentrations). Being able to rest a portion of the well field, by using an alternate source, the water ' quality should improve. If two 50 gallon per minute wells are located at the primary location, the wells should be at least 100 feet apart. The impact an maintainability ' of the wells will be enhanced, if three 33 gallon per minute wells are used. Hydrologic drawdown models (Table # 3, Wellfield Simulations) show that the maximum drawdown will be less for three 33 gallon per minute wells, t compared to two 50 gallon per minute wells. Subsequently, the possibility of upconing will be reduced (Table # 2, Salt Water Intrusion Model). A recommended well field configuration consists of three wells in a North South line, discharging 33 gallons per minute each. The two end wells should be drilled to a depth of approximately 60 feet and the center well ' should be drilled to 40 feet. The shallow well should be screened between 20 to 30 feet with a tail pipe to approximately 40 feet below land surface. If a submersible pump is used in the shallow well, a shroud is needed to insure adequate cooling for the motor (if the pump is set into or below ' the well screen). The well screen and gravel pack selection for the well construction should be based on sieve analyses of the screened formation, at each well site. Analysis at the test hole site revealed that the median ' grain size is roughly 0.15 mm, and the 90 per cent retained of the formation was roughly 0.1 mm, therefore, the median grain size of the gravel pack should be .40 to .45 mm. It is expected that the recommended screen opening should be 0.25 or 0.3 mm. An appropriate gravel pack material is Jesse Morie Gravel # 1 , to be used with a 25 slot screen. It should be understood that beach sands are bimodal (two distinct grain sizes) and that the deeper a hole is drilled in a regressive beach sequence, the finer the grain size. ' It may be difficult to construct an efficient well greater than 33 gallons per minute in this environment (probably due to the bimodality), therefore, 1 Mr. Bissell, P.E.

A loading rate of seven and one half gallons per day per square foot is safe and reasonable, because of the very permeable sandy soil and the sufficient depth to the water table surface at elevations greater than 8.5 feet above mean sea level. ' In order to safely discharge 70,000 gallons per day (GPD), it is recommended that a canal or pond be constructed within 400 ' feet of the discharge. The estimated ground water mound beneath ' the discharge is approximately 1 .5 feet above the water table surface at the center of the discharge. 1 INTRODUCTION The hydrodeologic site investigation of the proposed wastewaler disposal facility for Sea Watch I)evelupinenl, Currituck County, Ouler Banks, North Carolina (f=igure # 1, Site Location Map), focuses on the ability of the water table acluift'r to IrInsporl and discharge the rnaximurn daily effluent volume lhroucthoul the year(*rnole: Sea Watch was inilially named Currituck Dunes, Therefore, some figures and tables are so labeled) . The discharge will be up to 70,000 gallons per clay of lerl i.rry I realvd of l luent , which will be discharged using low head sprinklers in a high rate spray field. The use of spray beds versus the conventional rotary dislribulor syslem will provide for better conformity to landforms related to regressive beach ridge formalion. In order to discharge this volmne of Ireated effluent in a central location without adversely affecting surrounding surface water, a "high rate land application syslem" is recommended. Al several localions along the barrier islands, rotary distributors are used for high role discharges from 5 to 10 gallons per clay per square fool , I hroughout 1 he summer ,toil( hs .

X y1 Y ro A i analysis show that the site can effectively disperse, diffuse and transport (advection) effluent off of site. An analysis of the ability of the water table aquifer to transmit the total volume of the desired discharge was made using the Darcy Equal ion. This revealed that a discharge of 70,000 gallons per day could be made based on a 250 fool. line sink located w ithin 400 feet o f the discharge. All of the hydrologic analyses and calculations are made using maximum daily discharges for 365 day r pe year. The measured depth to the water table was 2.7 feet 10 with an expected increase of approximately one foot in the winter months. Sufficient elevation will be needed to insure an unsaturated buffer above the ground water mound. 7- 17 LI -5- IL, 4 IL HYDROGEOLOGY The determination of loading rate is based on the hydraulics of the unsaturated zone. The unsaturated zone is described as the area beneath the discharge, where gravity drainage occurs, i this area is located above the seasonal high water table, the resultant round water mound and the c r ill M t f th g ap a y zo ne. easuremen s o e infiltration rates at 1 foot and two feet below land surface using double ring infiltrometers resulted in rate s greater than 75 inches per hour. Even after attempted pre-saturation the measured infiltration rates are high because of the relationship of the wetted front which has a large vecloral component in the horizontal direction. During a continuous large (70,000 gallon per day) discharge the infiltration rate will be reduced in proportion to the loss in lateral flow direction. For the purpose of planning the infiltration rate should be estimated under discharge conditions to be 20 inches per hour. Short term or intermiltant discharges will more closely reflect [lie measured infiltration rate. -6- IL C1 14 k a L L L IL 0.4 1 The measured rates are: Site depth infillralion rate DR--I surface 94.2 in. /hr. 1 fool 77.4 in./hr. 2 ft. 129.6 in./hr. 2.5 feet 118.11 in. /hr.

GEOLOGY AND SOILS The predominant soil series encountered ill the proposed waste lrealmenl area are the Newhan Corolla, thmeland Newhall, mid the Dmkslon line sand series. u i(pire # 3, Soil Mal) )(Tahle # 1, SCS Dif It Skeels, Appendix). The Newkan Corolla series (which consists of two soils) occupies Ike Iransilional zone between the higher lying dunes to the east and the broad flals to the west. Il consists of low dunes wilh short complex slopes and the nearly level intervening basins Ikat separale the dunes. They arc formed in slralified sandy deposits Ihal contain mostly coarse sand and varying anwunts of shell fracpmenls. The Durieland-Newhan series (which also consists of two soils) is in Ike area of dunes Ihal parallels the ocean. This deposit is periodically affecled by wind and is typical of a regressive beach ridge sequence. Finally, the Dmkston fine sands occur along flals along the edge of the fresh waler inarshes. They are in the smaller depressions between the higher lying arel-is of the Newhan Corolla soils, and have been formed in sandy marine scdimcnls. According to the SCS Data Sheets, all these sands are well drained. -8-- nyl y 20 % lh?'11 A NiP ?,1 +? r , r ,sr,• 4 jt9' + T ?? 1 .?i i' ?

However, field investigation revealed significantly higher values, which were measured in an unsaturated condition using a double ring infiltrometer. A double rind infiltrometer will reflect the horizontal component of flow due to diffusion during gravity drainage. This will simulate actual conditions encountered from a low pressure spray field (hie to grdvily drainage (salurated flow regime is analysed in the Aduifer Ilydrolocly sect ion of this report).

There were no significant restrictive layers present that would inhibit vertical flow. Lateral flow will occur in the saturated zone toward the west (the Sound acting as a line sink). The geology and soil across the site appears to be homogeneous and isotropic (Figure 3A, Grain Size Distribution Analyses). These analyses indicate that the median grain size is (generally greater than 0.2 nun (fine to medium sand) and that the slope of the cumulative frequency curve indicates a very well sorted sand. -11- 1 i 11 J U AQUIFER HYDROLOGY In order to define the aquifer characteristics of the water table aquifer, a twenty four hour aquifer test was performed to determine Transmissivity (T) and Specific Yield (SY)(Table # 3, Aquifer Test Results); however, tidal fluctuation distortion after 4 hours of testing obfuscated the water level decline due to pumpage. The measured thickness of the water table aquifer is estimated to be 40 feet. The test consisted of one 40 foot deep observation well, one 40 foot deep pumping well, one Stevens Recorder, one Keck Instrument, and over 300 feet of discharge line. The distance from the observation well to the pumping well is 36 feet. Using Boulton type curves resulted in a range of Transmissivity from 3500 to 4300 ft2/day. The TY calculation resulted in a T = 3547.72 ft2/day. The pumping rate was 17.6 gallons per minute, which resulted in a total drawdown of 0.42 feet after 240 minutes. After 240 minutes, fluctuations distorted the drawdown measurements. The analysis of the early portion of the test provides an accurate determination of Transmissivity; however, Specific Yield can not be calculated. The Transmissivity is measured over -12- 1 1 1 1 1 1 L?'

For the purpose of conservative analysis, Transmissivity will be used at 2500 fl2/day and Specific Yield at 0.15. (Experience in other beach environments shows a Specific Yield from 0.12 to 0.30). The ability of the water table aquifer to transport the discharged effluent off of the site is the limiting hydrologic: factor that determines the maximum volume that can be loaded onto the site (loading capacity). In this analysis, it is necessary to determine if the maximum safe loading capacity is greater than the desired discharge of 70,000 gallons per day. For this 70,000 gallons per day discharge to operate satisfactorily, the water table aquifer must discharge to a neighboring surface water or a 'drainage system at a su,fficienl rate over a sufficient stream length in order to prevent hydraulic failure on the site. In order to calculate the maximum safe volume, the Darcy Equation J 1 I A a is used to define the expected conditions for the designed infiltration basins. The Darcy Equation is expressed as: DARCY EQUATION Q=T*W*dh/dl -15- 1 C u J 1 1 1 1 1 i i Desired Q = 70,000 gallons per day or 9,358.3 f t 3 /day Transmissivity (T) = 2500 sq. ft/day Stream Width (W) = 200 feet Maximum Water Level (dh) = 8 ft. above road ditch elevation Distance to line sink = '100 feel. 2500 * 200 * 0.02 = 10,000 ft3/day, which is greater than the recommended loading capacity of 9358.3 ft3/day. In order to increase the site loading, enhanced subsurface drainage is needed within 400 feet from the discharge. The determination of the time to steady shape or to steady state is derived using the distance to the line sink or surface water and the distance to the interception of length (W) respectfully. TIME EQUATION to = Sro2/2.25 T -16- i 1 1 1 1 i 1 i 1 1 I S = 0. 15 to to steady state is based on ro= 400 feet. Time to steady state is 4.27 days. The result of a discharge from a 70,000 GPD spray bed is a ground water mound. For this initial discharge, at the steady state conditions of 4.27 days, . the ground water mound directly beneath the spray bed is less than 2.0 feel above the water table surface (Table # 4, Computer Derived Mound Analysis after liantush). The seasonal high water table is approximately 2.0 feet below land surface at elevation 8.5 feet. In order to accommodate the mound height with the seasonal high water table at two feet below land surface, the use of hydraulically compatible fill will be necessary to reduce the risk of breakout at elevations less than 8.5 feet, beneath the discharging spray beds. The fill should be sufficient to account for seasonal high water table, depression areas, the ground water mound, which will be less than 1.5 feet at the center of the spray bed, and a buffer. In other words, low lying areas (less than 8v5 feel m.s.l.) will probably have to be raised, in the area of the discharge basins. The fill should be contoured from ' the edge of the discharge basins, using the mound height contours and adding approximately one foot of buffer for areas between spray beds and -17- COMPUTER ANALYSIS Currlluck Dunes Ground water mound calculation (Ilantush, 1967) 1rlt .nfl 111.1 rrl!allrl nlrn ruin11'r (FT1 F,.f.76.0' Crirl "Note: the use of exponents 11^•nrrl 14111. u:Igww r r)• •,.

The fill should be clean, well sorted (less than 2.0 sorting coefficient) with a medium grain size greater than 0.2 mm). This estimation is based on the results of the computer analysis for an initial high rate spray bed with an area of 111,000 square feet, and a loading rate of 5.0 gallons per day per square foot. The computer model is based on a discharge from a circular area with a radius of 66.76 ft. (111,000 square feet). It appears from initial calculations that it is feasible to discharge 70,000 gallons per clay provided the discharge basin is located or elevated (using well sorted very permeable medium sand) to an elevation greater than 10 feet above MSL. It is recommended that additional line sink length be located nearer than 1100 feet from the discharge. The use of drain tile surrounding the discharge area draining to the line sink may be a perferred way to control the ground water mound height. This analysis is a complete predictive hydrologic analysis. However , as a predictive analysis, it is understood that actual conditions may vary. I expect that the ground water mound will be less than predicted and with careful observation the fluctuations of the water table and the effectiveness of the line sinks can be determined. Therefore, I recommend carefcll hydrologic monitoring, together with the required water quality monitoring. t A ' -19- L ti ti ti ti ti ti y y CONCLUSIONS AND RECOMMENDATIONS Based on the hydrogeologic site evaluation at the Sea Watch Development it appears that the site is suitable for a moderate volume (70,000 gallon per day) discharge at a high loading rate (7.5 to 10 gallons per day per square foot). The ground water mound height from the discharge is approximately 1.5 feet at the center of the discharge, therefore, the risk of breakout is low even though the estimated seasonal high water table is two feet below land surface at the test site. It is recommended that the site be elevated to at least three El 1 feet above the seasonal high water table and that line sinks (ponds) be installed within the four hundred feet used in (his analysis. If possible a line sink longer than 300 feet, oriented North-South should be constructed, combined with a drain the system closer to the discharge area. It will also be necessary to have the effluent treated so that Synthetic Organic Compounds (SOC) will not be discharged to the ground water. Land application in beach ridge sand formations does not effectively treat Synthetic Organic Compounds. - 20- 1 u C l 1 1 1 r. D
