Approximately 57 townhomes and a clubhouse are proposed for construction The townhome project is to be located on the site of a former mobile home park. The property is mostly flat, with some trees located on the property. The Town of Swansboro recently rezoned the property to R-6 Residential District to allow construction of the townhome project and has given preliminary subdivision approval to the project. The development will be served by municipal water and sewer service. The Hammocks at Port Swansboro has received a sewer allocation for the project, and adequate water capacity is currently available. There are no local stormwater or erosion control agencies or ordinances with jurisdiction over the project site. The applicants are pursuing express permits to develop the project. In addition to stormwater and erosion and sedimentation control approvals, the project will require appropriate authorization to extend municipal water and sewer facilities to the site. There are no CAMA AECs located on the property and only a limited area of wetlands. The US Army Corps of Engineers (USACE) has concurred with the delineation of a small area of jurisdictional wetlands on the southwestern corner of the property. A very small area of wetlands (approximately 100 square feet) will be impacted by the i installation of a sewer line. An on -site meeting has occurred with an USACE representative, who has confirmed that the proposed activity is eligible for a Nationwide Permit. An On -site evaluation by the Division of Water Quality has determined that the project site is within one-half mile of and draining to SA waters or unnamed tributaries to SA waters. The project proposes to manage stormwater in accordance with requirements for high -density development. An infiltration system designed to control the runoff from all surfaces generated by one and one-half inches of rainfall is the primary stormwater management mechanism included in the project_ Stormwater containment and subsequent recharge within the infiltration system will be facilitated by use of the "Storm Chamber" system (or equal) manufactured by Hydrologic Solutions. Additional information regarding stormwater management is included in the Stormwater Management Narrative included with the Stormwater Management Permit Application Form. RECP' INTr;L-) OCT I P Z006 BY: Stormwater Management Narrative The Hammocks at Port Swansboro 1143 Hammocks Beach Road Onslow County Swansboro, NC 28584 The Hammocks at Port Swansboro is a proposed 6.57 acre, 57 unit, townhouse development. The project is within a coastal county and, per an on -site evaluation by NCDENR personnel, determined to be "within one-half mile of and draining to SA waters or unnamed tributaries to SA waters". The project is to manage storm water in accordance with the North Carolina Administrative Code, section I SA NCAC 2H.1005 (2) (b)), regarding high density development. An infiltration system designed "to control the runoff from all surfaces generated by one and one-half inches of rainfall" is the primary storm water management mechanism included in the project. An evaluation of the infiltration area as to the site's suitability for the intended purpose was performed and is included with this submittal. Stormwater containment and subsequent recharge within the infiltration area is to be facilitated by the use of the "Storm Chamber" system (or equal) manufactured by Hydrologic Solutions. The system is to be installed such that its bottom is a minimum of two feet above the seasonal high water table. This level is approximately at the existing infiltration site grade. The Storm Chambers and associated stone, et cetera will be installed within fill material placed above this elevation. Therefore, the required design storm water volume shall be collected in other areas and pumped into the elevated Storm Chambers. The project site has been divided into two drainage areas each with its own runoff collection system. In each of the drainage areas stormwater is to be collected from the surface by catch basins adjacent or within the project streets. The storm water is then to be conveyed via gravity flow through piping from the catch basins to concrete tanks (one for each drainage area). At the pipe inlets the tanks are to provide sediment or grit chambers which drain to separate pump chambers equipped with pump and switch systems. The pump systems are designed to jointly deliver a volume equivalent to the runoff from all surfaces generated by one and one-half inches of rainfall to the Storm Chambers. Runoff in excess of this volume is to bypass the infiltration system by being permitted to overflow directly from the two pump chambers to appropriate vegetative filters and existing drainage routes. The excess runoff will be distributed across a forty (40) foot long level concrete slab on grade at each pump station to achieve sheet flow distribution. Maintenance: The pumping equipment used for this project will require proper routine maintenance and shall be preformed in strict accordance with the manufacturer's requirements. Any malfunctions in pumping operations will be automatically noted at the control panel of each pumping station by audible and visual appurtenances. In addition, we recommend that at a minimum, a monthly inspection is made, recorded and filed by the project owner of the entire stormwater system. The StormWater Chamber System has been provided with adequate inspection ports as designated by the manufacturer to inspect and remove any sediment that accumulate in the chamber system. Properly maintained and managed, the majority of sediment materials will occur in the influent chamber of the pumping stations.

The project site consists of approximately 6.57 acres and fronts both NC Highway 24 (Corbett Avenue) and Hammocks Beach Road (NCSR 1511). Approximately 75 townhomes are proposed for construction. C—rrf The townhome project is to be located on the site of a former snob' e ar . The property is mostly flat, with some trees located on th ere are no CAMA AECs located on the property and only a limited area of wetlands. The US Army Corps of Engineers has concurred with the delineation of a small area of jurisdictional wetlands on the southwestern corner of the property. The developer of the project intends to avoid the wetland area in the design and construction of the project. The Town of Swansboro recently rezoned the property to R-6 Residential District to allow construction of the townhome project. The development will be served by municipal water and sewer service. The Hammocks at Port Swansboro has received a sewer allocation for the project, and adequate water capacity is currently available. There are no local stormwater or erosion control agencies or ordinances with jurisdiction over the project site. The applicants intend to pursue express permits to develop the project. In addition to stormwater and erosion and sedimentation control approvals, the project will require appropriate authorization- to extend municipal water and sewer facilities to the site.

April 7, 2006 Jeff Gillette PCR Investments, Inc. P.O. Box 384 Swansboro, NC 28594 Reference: Storm►water study for the Hammocks at Port Swansboro near Swansboro, NC. Dear Mr. Gillette: Lid Management Group, Inc. has m=ntly had the pleasure of evaluWing the aforcmarWoned stormwater infiltration site. The purpose of the evaluation was to examine a typical soil profile, quantify the depth to the seamnal high water sable, to measure the infiltration: rates and to infoini the project engineer of any poten" limitagons of this project. I offer the following comments. My first task on this site was to identify the best area to propose for the infiltration systau I identified an area with a seasonal high water table in excess of 24" with the best soil and site conditions for infiltration. The area identified as well as the best plot locations are being shown on a separate correspondence from Mr. Wysodd,s office. The soils in this location are best described as the Onslow soil series and have a seasonal high water table between 24" and 32" from the soil surface. This area has been modified in the past by the placement and removal of mobile homes, installation of septic tanks and drmnfields, and vehicular parking. A detailed profile description that typifies the soils in this area is attached For Comparison, I have included the current official NRCS description of an Ondow, soil series. Due to the past land disharbance activities, it was required that infiltration rates be Measured instead of utilizing estimates. In order to accomplish this task. I employed 2 different field techniques, the double ring infiltrometer and the compact constant head perma meter. The soil located at approximately 24" above the seasonal high water table was the focus of this study. This soil that is 24" above the seasonal high water table was primarily the A and E/Bh horizons. I used the double ring infiltrometer to test the upper 2" of the soil surface, both in compacted and wwompacted areas. I used the compact constatnt head permeameter to test the hydraulic conductivity at S". 9 and 10" from the soil surface. The devices were used as follows: Double ring infiltr meters were used at three locations to test the infiltration rate Of the upper two inches of soil. A, total of eleven memsurements were reported. The infiltration rate was determined by the adaptation of Darcy's Law: 04r nr/ GCR7b IZ:l9Y) 9104b20860 LANDMANAGEMENT PAGE 03/09 EP Vi=Kw(Hw+Lf—hf)lLf Where Vi — infiltration rate, Kw = hydraulic conductivity of the wetted zone, Hw = the water depth above the soil, Lf - depth of the wetting Brent, and hf — pressure head of water at wetted front as described in Methods of Soil Analysis, Part 1 (A. Klute,1986). A compact constant had petmcameter (CC13P) was used to determine the saturated hydraulic conductivity of the sod. The compact constant head permeameter was set to nm at one depth in three locations for a total of three measurements. The hydraulic conductivity was calculated utilizing Glover's solution to Richard's equation for a shallow well pump in test. Details of the methodology are described in Medwds of Soil Analysis, Part 1 (A. Klute, 1996) and Compact Constant Bead Per eameter: A Convenient Device for Measuring Hydraulic Conductivity (Amoozegar,1992).

Both values conform to the published range for this soil type. From a design stand point, I would recommend an infiltration rate that does not exceed 6.3 inches per biour. Due to the inherent compaction of this site and the complex lintoary of past uses, I would specifically recommend that the design a ngm= use an infiltration rate of 2 inches per hour. This rate conforms well to the lowest double ring infiltromete r value collected, the highest CCHP value collected, the published range of values, and is a fraction of the actual measured values which tended to concentrate in accessible and uncompacted areas. In summary, the site should be proposed for stormwateyr infiltration with a seasonal high water table that varies from 24" to 32" across the site and has a measured infiltration rate of the upper teas inam of soil in excess of 2 inches per hour. I did not observe any other facie rs that would limit the ability of this site to serve as a stonnwater infiltration area. As always, the appropriate regulatory agency will have £mal permitting authority in this matter.

THIS CHAMBER WILL PROVIDE FOR THE COLLECTION OF SEDIMENT PRIOR TO THE STORMWATER BEING PUMPED TO THE INFILTRATION SYSTEM. EACH COLLECTION TANK WILL CONTAIN THREE (3) SUBMERSIBLE, CENTRIFUGAL, NON -CLOG GRINDER PUMPS; PUMP STATION No. 1: 400 GPM, 20'TDH-5HP,1750RPM7230V, 1 PH FOR A TOTAL CAPACITY OF 12000PM. PUMP STATION NO. 2: 400 GPM, 20'TDH-5HP,1750RPM,230V, 1 PH FOR A TOTAL CAPACITY OF 12000PM. PUMP SYSTEM SEQUENCE OF OPERATION OPERATION AND SEQENCING OF THE PUMPS WILL BE ACHIEVED BY THE USE OF AUTOMATIC FLOAT LEVEL SWITCHES LOCATED WITHIN THE PUMP CONTAINMENT CHAMBER WHICH WILL INITIATE CONTACTS LOCATED WITHIN THE REMOTE NEMA 4X PUMP CONTROL PANEL. PUMPS WILL ALSO BE CONTROLLED FOR RUN TIME AND ALTERNATION BY A PROGRAMMABLE LOGIC CONTROLLER(PLC). THE LOGIC FOR THE PLC IS INCLUDED ,AS AN ATTACHMENT HERETO. 1 AS THE WATER LEVEL RISES TO THE ELEVATION FOR A LEVEL FLOAT TO "MAKE" THEN THE NEXT PUMP IN SEQUENCE WILL START. IF THE WATER LEVEL CONTINUES TO RISE, THEN A SECOND PUMP WILL START, AND UPON A CONTINUED RISE IN WATER LEVEL A THIRD PUMP WILL BE ENABLED. AS THE WATER LEVEL FALLS WITHIN THE PUMP CHAMBER THEN THE INVERSE OF THE ABOVE DESCRIBED CONTROL SEQUENCE WILL OCCUR, WITH EACH PUMP BEING SHUTDOWN AS THE LEVEL FALLS BELOW EACH OF THE FLOAT LEVEL SWITCHES. UPON CESSATION OF PUMPING, AND THE NEXT EVENT CYCLE OCCURS THAT WILL REQUIRE A PUMP START, THEN THE PLC ALTERNATOR BLOCK WILL SELECT THE NEXT PUMP THAT WAS THE LAG PUMP UPON THE PREVIOUS CALL FOR A PUMP START. THIS WILL ASSURE EQUAL RUN TIME, AND THUS EQUAL WEAR ON EACH OF THE THREE (3) PUMPS IN EACH PUMP STATION. IF THE WATER LEVEL CONTINUES TO RISE WITHIN THE PUMP CHAMBER WHILE THE PUMPS ARE OPERATING, THEN A "HIGH WATER" LEVEL FLOAT WILL INITIATE AN ALARM CONDITION INDICATION WITH THE ACTIVATION OF AN AUDIBLE ALARM HORN, AND A VISUAL ALARM STROBE LIGHT DISPLAYED ON THE PUMP CONTROL PANEL. THE DESIGN CONDITION OF THIS SYSTEM IS TO ACCOMMODATE THE CONDITION OF 1.591 OF RAINFALL. ANALYSIS AND RESEARCH REGARDING THE POSSIBLE SCENARIOS AND CONDITIONS THAT MAY BE FORESEEN DURING THIS EVENT HAVE BEEN THOROUGHLY EVALUATED_ AS A RESULT, IT IS DETERMINED THAT THE CONTROL OF THE "RUN-TIME" FOR ALL THREE(3) PUMPS BY THE PLC WILL ALLOW THE PUMPS TO OPERATE FOR A CUMULATIVE PERIOD OF FIFTY- FOUR(54) MINUTES. 2 AFTER THIS TIME PERIOD THE PLC WILL NOT ALLOW A PUMP START. AFTER A PERIOD OF FORTY-EIGHT(48)HOURS HAS LAPSED, THEN THE PUMP CONTROL SYSTEM WILL BE ENABLED TO ALLOW CONTINUED OPERATION AS HERETOFORE DESCRIBED. AFTER THE FORTY-EIGHT(4E) HOUR TIMER HAS "TIMED -OUT", THEN THE SYSTEM CONTROLS WILL "RESET" TO ALLOW NORMAL OPERATION AND CYCLING OF PUMPING. IN THE EVENT OF THE CESSATION OF ALL PUMPING, AND A CONTINUED RISE IN WATER LEVEL OCCURS, OVERFLOW WEIRS LOCATED IN THE TOP OF THE PUMP CHAMBER WILL ALLEVIATE THE CONDITION BY ALLOWING WATER TO OVERFLOW ON TO A CONCRETE APRON SURROUNDING THE PUMP STATION. THIS CONCRETE APRON WILL DIRECT THE WATER TO A CONCRETE WEIR TO ALLOW FOR SHEET FLOW DISPERSION. OPERATION AND MAINTENANCE THE STORMWATER COLLECTION AND INFILTRATION SYSTEM WILL BE INSTALLED IN ACCORDANCE WITH ALL MANUFACTURERS INSTRUCTIONS AND RECOMMENDATIONS; (SEE ATTACHED DOCUMENTATION). THIS SPECIFIC INFILTRATION SYSTEM IS DESIGNED AROUND HYDROLOGIC SOLUTIONS' i°STORM CHAMBER SYSTEM". PERIODIC INSPECTION OF THE INFILTRTION SYSTEM WILL BE CONDUCTED ON ROUTINE. REGULAR BASIS TO ASCERTAIN OPERATING EFFICIENCY AND TO ASSURE THAT THE COLLECTION OR "BUILD-UP" OF SEDIMENT WITHIN THE STORM CHAMBERS IS NOT PREVALENT. THESE INSPECTIONS WILL BE DOCUMENTED AND FILED WITH THE OWNING AGENCY. 3 ANY MODIFICATIONS OR CHANGES OR ALTERATIONS TO THIS SYSTEM REQUIRED BY THE MANUFACTURER WILL BE ACCOMODATED AND INCORPORATED IN A TIMELY MANNER, AND DULY DOCUMENTED AND RECORDED. 4 i\ 1 Sfl Electrical Data MODEL: SH-Non-Clog Sewage pump section NON -CLOG Page 305 Dated SEPTEMBER 1993 R.P.M. 1750 MOTOR TYPE ENCLOSED, OIL COOLED INDUCTION MOTOR DESIGN NEMA TYPE B (3o) L (1o) GENERAL INSULATION CLASS B STATOR WINDING CLASS F MAXIMUM STATOR TEMPERATURE 311 OF MOTOR PROTECTION BI-METALLIC, TEMPERATURE SENSITIVE DISC, SIZED TO OPEN AT 1200C AND AUTOMATICALLY RESET @ 30-350C DIFFERENTIAL, ONE IN SINGLE PHASE, TWO IN THREE PHASE VOLTAGE TOLERANCE *10% 3 200 1 G 1.2 19.6 22.9 91.0 3.3 18.2 3.9 .67 .67 .65 .57 .88 .85 .80 .71 230 17.1 20.0 79 .0 3 200 3 J 1.2 10.9 12.8 64.5 3.1 22.3 3.8 .73 .72 .70 .64 .83 .82 .80 .72 230 9.5 11.1 56.0 460 4.8 5.6 28.0 575 3.8 4.5 22.5 200 1 G 1.2 33.9 39.3 144 5.7 28.8 6.8 .66 .66 .65 .60 .87 .84 77 .64 230 29.5 34.2 125 5 200 3 J 1.2 17.6 20.6 108 4.8 37.4 6.1 .79 .79 .77 .72 .80 .78 .73 .62 230 15.3 17.9 94.0 460 7.6 8.9 47.0 575 6.1 7.2 37.6 7.53 1 K 1 1.2 29.0 32.9 194 7.2 67.0 10.1 .78 .78 .76 .71 .76 .72 .66 .56 M4660 25.2 28.6 168 12.fi14.384 10.1 1 11.4 67.2 AURCRAPUMP - uvnDnmAT1f - DI1MDC
