49 Project Description The following narrative will detail the stormwater management plan for the proposed Foxglove Acres subdivision located in Moyock, Currituck County, NC. The subject property is located along Tulls Creek Road, Moyock, NC approximately 0.6 miles eastward from the intersection of Panther Landing Road and Tulls Creek Road. The property is located along the southern side of Tulls Creek Road and previously known as Lots 1 & 2, Ward Acres Subdivision. The site development proposed the construction of a street, sidewalks, 13 residential lots, open space that includes stormwater control measures (SCM s) and associate utilities such as power, watermain, and fire hydrant assemblies. The project will also include two parking spaces (one of which will be a van accessible ADA space) and a cluster mailbox unit near the front of the subdivision. The following narrative, application, and calculations will demonstrate the parameters of the proposed subdivision design, which will illustrate an effective stormwater management system in compliance with all State regulations. Summary of Existing Conditions The existing acre project area is currently vacant and consists of agricultural fields and woods. There are three agricultural ditches that run through the project, a major drainage ditch that follows the southeastern property line and a roadside ditch along Tulls Creek Road. There are no wetlands within this project area. Existing ground elevations range between 5 to 8 with an average slope of 0.3%. Existing stormwater runoff is via sheet flow to the agricultural ditches that run through the properties. These ditches direct runoff to the major drainage ditch along the southeastern property line to Tulls Creek Road which then leaves the property eventually making it to the Northwest River. The site does not currently have any existing built upon area and only has one drainage area (DA 1). The boundary for DA 1 is provided within Appendix A on the Drainage Area Maps. Summary of Proposed Conditions The project proposes the construction of a street, sidewalk, 13 residential lots, open space that includes stormwater control measures (SCM s) and associated utilities such as power, watermain, and fire hydrant assemblies. The subdivision will propose 248,260 sq.ft. of coverage including a wet pond permanent pool area of 52,072 sq.ft. Upon completion of the proposed improvements, the sites overall BUA will be 34% of the drainage area. The proposed Built Upon Area (BUA) summary table can be seen on Table 2 below.
50 Table 2: Proposed Built Upon Area Summary Land Cover Description Drainage Basin 1 (sq.ft.) (acre) Drainage Area = 739, Open Space 491, Lot BUA = 161, Right of Way BUA = 33, Open Space BUA = Pond = 52, Total Impervious = 248, Stormwater management improvements will be provided to treat runoff from all proposed impervious construction. The primary method of stormwater treatment will be via a wet detention basin located on the northeastern of the site. The wet detention basin has been sized to manage an overall impervious area of 248,260 sq. ft. All of these impervious areas are located within Drainage Area 1 on the post-development drainage area map. Stormwater Compliance Per 15A NCAC 02H.1005 (a) (3) (B) High Density Coastal Development is required to meet particular criteria. This development is proposed to have 34% of impervious coverage within the entire lot. The proposed wet detention basin onsite is designed in accordance with NCDEQ and Currituck County Stormwater Manual Requirements and is designed to store, control, and treat the stormwater runoff from all surfaces generated by the one and one-half inch of rainfall event (State Requirements) and route the 10-year post-development back to the 2-year predevelopment, wooded conditions (Currituck County Requirements). In addition to these requirements, a minimum 50 vegetative buffer from surface waters is provided. The High Density Residential Subdivisions Deed Restrictions & Protective Covenances Form will be supplied with the State Stormwater Permit Application and will include the table below for allowable Built Upon Area for each lot: Lot # BUA (sf) Lot # BUA (sf) Lot # BUA (sf) Lot # BUA (sf) 1 15, , , , , , , , , , , , ,030 Collection Runoff from the proposed impervious area is to be collected and conveyed to the wet detention basin via sheet flow to the lot line / roadside vegetated swales. The vegetated swales will then deliver the runoff to the proposed forebay of the wet detention basin.
51 Treatment The proposed system will offer several methods of treatment prior to release. Runoff from the residential lots will be directed to the lot line swales and roadside swales via sheet flow. The vegetated swales will provide the first level of treatment by the filtration of small particulates and nutrients prior to entering the wet detention basin. Riprap will be provided at the inlet to the pond from the stormwater conveyance connections. Stormwater entering the forebay will be deenergized by the riprap as to reduce inflow velocities to the basin. Larger debris and pollutants will settle on the riprap aprons as the stormwater enters the forebay. The primary treatment of runoff will be provided within the wet detention basin. Several modes of treatment are available in the wet detention basin. Runoff first entering the basin will lose velocity and large particulates and sediment will settle out primarily in the forebay. The vegetated side slopes and vegetated shelf will also provide filtration of runoff and nutrient uptake through natural biological processes. Storage The proposed wet detention basin has been sized to allow for a local requirement of routing the 10-year post developed condition back to the 2-year pre developed wooded condition. This storage capacity is in excess of the State required 1.5 inch and provides approximately 7.8 inches of storage in the basin. The storage required to completely capture the first 1.5 inch of rainfall is 32,600 cubic feet. The proposed wet detention basin will have a temporary storage capacity of 169,183 cubic feet. The temporary storage capacity has been calculated between the permanent pool elevation of 2.0 and the overflow spillway invert at 5.0. For NCDEQ calculations, the anticipated permanent pool and surface areas referenced in the application documents and attached calculations are measured at 2.0 ft. in elevation. Utilizing permanent pool average depth equation 2 from Section C-3 Wet Pond in the NCDEQ Stormwater Design Manual, the average depth was calculated to be 4.3 feet. Table 2: Coastal SA/DA Table from this Manual using a 35% impervious area and a 4.0 foot depth states that the minimum surface area to drainage area percentage is 1.96% (linear interpolation). The proposed surface area to drainage area for this project is 5.82%, far exceeding the requirements. NCDEQ calculations are shown in Appendix C. As stated above, Currituck County Stormwater Manual requires the stormwater design to route the 10-year post-development storm back to the 2-year pre-development storm in wooded conditions. The peak runoff of the 10-year post-development storm is 51.8 cubic feet per second (cfs) and the peak runoff for the 2-year pre-development storm in wooded conditions is 16.3 cfs. The peak discharge from routing the 10-year post-development storm through the proposed stormwater detention basin is 12.9 cfs equating to less than the 2-year predevelopment storm in wooded conditions, thus satisfying the Currituck County Stormwater Manual. The Currituck County Stormwater Calculations are shown in Appendix D. The attached soils analysis memorandum in Appendix B states that the seasonal high water table (SHWT) was approximately 30 inches below the existing ground surface at SB-1 identified
52 on the Drainage Area Map. Existing grade at SB-1 was surveyed at 4.53 feet in elevation, which puts the SHWT at an elevation of 2.03 feet. A rounded elevation of 2.0 was used in the calculations for the SHWT. The basin s 6 foot wide, 6:1 (H:V) vegetated shelf is specified to be constructed between the elevations of 1.5 ft. and 2.5ft. Disposal The wet detention basin s primary mode of disposal for elevations between 2.0 and 4.0 ft. is through a 6 drawdown orifice on a structure located inside of the main pool. The invert elevation of the 6 drawdown orifice is proposed to be at an elevation of 2.0 ft. Elevations between 4.0 and 5.0 feet will utilize the 2.0 by 2.0 stormwater spillway structure with a trash rack on top as well as the 6 drawdown orifice. The invert elevation of the rim of the spillway structure is proposed to be 4.0 feet in elevation. The total drawdown time from an elevation of 5.0 ft. is 2.54 days. Supporting calculations for the drawdown time and storage of the proposed wet pond have been provided within Appendix C. Larger storms that will cause the wet pond to exceed the elevation of 5.0 ft. will overflow through the 10 wide, riprap-lined spillway into the downstream stormwater system. Soils The USDA NRCS Soil Survey lists the soil in the vicinity of the proposed stormwater detention basin as described below: Ro Roanoke fine sandy loam This soil typically has 0 to 2 percent slopes. Roanoke fine sandy loam has a very high runoff class and is poorly drained. This soil is categorized in Hydrologic Soil Group D. To Tomotley fine sandy loam This soil typically has 0 to 2 percent slopes. Tomotley fine sandy loam has a very high runoff class and is poorly drained. This soil is categorized in Hydrologic Soil Group D. Quible & Associates, P.C. conducted a soil boring test in the vicinity of the wet pond. The soils observed were consistent with the NRCS soil description. The results of this boring are available in Appendix B. Calculations A copy of the Drainage and Storage Calculations are provided in Appendix C and Appendix D of this narrative. Summary and Conclusions The proposed stormwater management plan for this site provides stormwater treatment in excess of the requirements for the State and Currituck County. The proposed system will offer primary and secondary methods of treatment. This proposed design will adequately serve the stormwater management requirements of the site.
