Dave may not have known the status of this. Before I issue the permits for Huntington Park and Kensington Park, I need to know if any lots have been sold in Huntington Park. If lots have been sold, I must require that you submit a copy of the RECORDED deed restrictions for Huntington Park before I can issue the modified permit. If you recall, the modification was necessary to accommodate the offsite drainage from Kensington Park. I am prepared to issue both permits upon the timely receipt of this information.

You don't really need to modify this application since the permit already included 196,400 sq. ft. for future development. Since only 152,616 sq. ft. of that amount is being used, there will be 43, 784 leftover for additional future development or as a contingency amount . I will write a plan revision to cover this change. I will send Mr. xQa*iig his money back for the unnecessary 040733 Mod. PI-mg— In regards to the application for Kensington Park II, I moved the "Offsite" supplement that you had submitted with 040733 to the Kensington Park II application, where it belongs. Additionally, please redo the drainage area map and clearly label the new onsite pond and delineate its drainage area, label the offsite pond under 040733, label Kensington Park II and clearly delineate the area of Kensington Park II that is draining to the offsite pond.

Every time it rains, their back yards flood. Met onsite on .lanuary 4, 2007 with Ms. Ramero, Ms. Armstrong and with Mr. Fowler(representative for developer). A shallow Swale and possible berm were proposed to divert water from wetlands into the road-side curb and gutter. This is not really a stormwater issue, mostly a flood and county issue.

Newso ',P CRYSTAL COAST ENGINEERING Stormwater Treatment Narrative Huntington Park & Kensington Park The developer is currently in the process of constructing Huntington Park, an eighty seven (87) lot residential subdivision on a 36.04 acre tract located in the Williamsburg Plantation Development in Jacksonville, N.C.. This project was permitted in April of 2005 under SW8 040733. This "high density" project includes a Wet Detention basin to provide treatment of stormwater. The developer now proposes to construct Kensington Park, a thirty four (34) lot residential subdivision on a 10.15 acre tract located immediately to the north and west of the Huntington Park subdivision. The project area is tributary to New River (C:NSW) in the White Oak Basin. The proposed development activities are high density (BUA=42.33%). A portion (Lots 15 — 34 & all streets) of the Kensington Park subdivision is located within the drainage area of the existing Huntington Park pond. Therefore, stormwater emanating from this portion will be diverted to the existing Huntington Park Pond. The pond must be enlarged to accommodate the additional impervious surfaces. The remainder of the Kensington Park subdivision (Lots 1-14) is not tributary to the existing pond. Therefore, a new Wet Detention Basin is proposed to provide treatment from stormwater emanating from this portion.

A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Please revise Section 111.6 on page 2 of the application so that the total proposed built-upon area matches up to what is provided for in the calculations, i.e., 912,694 square feet. The application only shows a total proposed BUA of 900,108 square feet. Please include the 12,586 square feet of existing street impervious area in the proposed total since that BUA will remain as part of the BUA total draining to the pond. "Proposed" is a misleading term in that even though 12,586 square feet of the total BUA draining to the pond is existing, it is "proposed" to drain to the pond. 2. The required proposed deed restrictions have not yet been submitted, as was previously requested. Please note that this request for additional information is the result of a preliminary review. The information submitted in response to this letter will be reviewed within 90 days of receipt, and if it is determined to be incomplete or if it generates more questions, more information will be required. The currently requested information should be received in this Office prior to November 20, 2005, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the permit. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Using orifice equation, solve for Diameter(D) that results in 3-1/2 day period: D =(Q 10.026 (h)s).5 Where: Q = (Control Volume / 3.5 days x 86,400 sec/day) 0.435 cfs h = d12 = 0.94 Solving for D: D = 4.15 Use 4.00 orifice Actual Drawdown with actual drawdown pipe diameter(using orifice equation): Q= 0.403 cfs Draw Down Period = 3.77 days OK , < 5.0 6. SELECT OUTLET STRUCTURE DIAMETER Size outlet structure such that depth of Q10 flow<1.0 feet: Using Rational Formula (Q=CIA)where: Cimper= 0,8 Cpery = 0.2 Ccum = 0.35 110 = 6.50 in/hr A = 89.99 ac Q10 = 204.72 cfs Assuming 1/2 circumference is used as weir and using Francis Formula (Q=3.33LH''5) to solve for L such that H = 1.0: L = 61.48 Feet Use 60 inch diameter outlet structure 7. DETERMINE Q10 STAGE Q10 = 204.72 cfs Using Francis Formula (Q=3.33LH'5) solve for H: H10 = 3.94 feet 8. DETERMINE Q100 STAGE (ELEV. OF EMERGENCY SPILLWAY) Using Rational Formula (Q=CIA)where: Ccum = 0.35 1100 = "78750 in/hr A = 89.99 ac Q100 = 267.71 Using Francis Formula (0=3.33LH"5) solve for H: H100 = 4.71 feet 9. DETERMINE Q100 STAGE OVER EMERGENCY SPILLWAY (TOP BERM ELEV.) Assume primary spillway blocked (i.e., emergency spillway to accommodate Q100) Emergency spillway shall be a broad crested earthern weir designed to pass 100 year storm. Using broad crested weir equation H = (Q/Cw x L)113 where: Q =Q100 267.71 cfs Cw =3.0 Length = 100 feet H = 0.93 feet 10.
