The consensus was that the entire vegetated shelf needs to be provided. It was also noted that a plan revision or similar request should have been submitted prior to making the changes to the approved design. Considering the pond's current condition, 3 options were offered: Remove the rip rap and filter fabric from the vegetated shelf and plant as specified. A plan revision should also be submitted documenting the revised pond design. Submit a modification to the permit to modify the pond to raise the orifice invert in order to create the required vegetated shelf above the rip rap line.

With a few minor adjustments left to do, the pond is ready for my PE certification except for the required plantings on the littoral shelf. As I mentioned on the phone today, the SECU site contractor had quite a problem earlier this year when he began his work. With the seasonal high groundwater being recorded at elevation 7.25, the contractor had trouble excavating to elevation 1.0. As you can see in the enclosed photo named " SECU Retention Pond Sand", the wet sands ran continuously not allowing the contractor to shape the bottom of the pond as required. SECU relied on their project geotechnical engineer, Geotechnologies, Inc, to help them resolve the problem which is apparently common in this area. With a combination of dewatering and installing a layer of rip rap / filter fabric along the inside walls of the pond from elevation 1.0 to approximately 7.0, the contractor was able to stabilize the lower portion of the wet pond to the required dimensions (which have been verified with an as -built survey). Do to this constructability problem, the contractor is now unable to plant the shallow water plants. I have enclosed one other picture of the finished pond configuration for your information and review. I am prepared to instruct the contractor now to go ahead and install all the required shallow land plantings prior to final inspection and certification but I wanted to discuss this matter with DWQ before we did anything. As I mentioned on the phone, I am available to meet with you to discuss this matter either at your office or at the site as you deem necessary.

The site is currently covered with a grass mixture and has been left uncut for sometime. Topography is fairly flat with elevations ranging from elevation 8 at the front of the property to elevation G along the rear part of the parcel. There 15 currently a small channel running through the middle of the site draining from front to back. This channel has been field verified by ACOE personnel and we have received a Jurisdictional Determination stating that there are no waters of the U5 present on th15 51te. A COPY of th15 1 0/ 1 1120 1 1 letter is enclosed in this report. The total area being disturbed for the project is 3.42 acres which takes into account a proposed deceleration lane along U5 70 as required by the North Carolina Department of Transportation. The site is tributary to Gibbs Creek within the White Oak River Basin and 15 within V2 mile of 5A/HQW waters (Index # 2 1 -35- 1 - 10). This proposed plans call for the development of a +/- G,700 5J. Credit Union office and associated parking lot. The site will be serviced by Town of Beaufort public water and wastewater collection. The total proposed overall impervou5 area 15 G4, 150 s.f. or approximately 54.9% of the total 5ste area. Due to the existing site grade constraints not all of the proposed impervious area has been routed to the 5tormwater wet pond due to the existing topography and elevation of the Pinner5 Point Road and Highway 70 ex15ting ditch fine grades. In order to provide the permanent pool level within the required G-inches of the seasonal high water table, it was necessary to raise the site approximately G-feet and make the road connection tie-ins, which makes it difficult if not impossibie to route all of the new impervious areas to the proposed pond. However, we have maximized the impervious areas draining to the pond to the greatest extent p05511?le and have designed the wet pond surface area based upon all of the on -site impervious area. Approximately 0.09 acres of impervious area will drain along the NC Hwy.70 and Dinners Point Road ditch line. The proposed site plan will provide for an 'overall 5tormwater management plan that includes wet pond surface detention to detain the increase storm water runoff. There will be an enclosed Storm drainage system which wili empty into the pond forebay. The storm water design is High Density Commercial, Coastal Storm water regulations. 51nce the wet pond is located within �/2 mile of 5A Waters the pond has been designed to capture the difference from the pre -developed runoff volume and post -developed runoff volume and Slowly release �t over a 2-5 day time period. The wet pond has al5o been designed for 90% T55 removal. In addition, we have designed an engineered Level Spreader / Vegetated filter 5trap per 5tormwater rule 15 A NCAC 2H. 1008 (c)(4) and 5e55ion Law 2008- 201 1 for Coastal Counties for the discharge from wet detention basins. There 15 no off -site runoff coming onto the 5+te or into the proposed BMP. In addition, the project does not have buffer requirements and the project is not located within a buffer. The flow leaving the 5tormwater wet pond has been routed to the existing natural channel and released at or below the pre -developed Q-1 24 hour storm peak rate and Q- 10 24 hour storm peak rate. Plea5e find a summary of pre -developed conditions compared with the po5t- developed conditions on the following page. r The proposed wet detention basin holds ail proposed storm events up to the Q- 100 while providing i ' of free board minimum. The permanent wet pond will be utilized as temporary erosion control measure (riser basin). Temporary diversion berms/ditches will convey runoff to the riser basin. Please refer to Pre -developed Drainage Area Map DA- I for the pre -developed drainage patterns leaving the site. Currently, the pre -developed drainage pattern on -site is divided into two drainage areas (On -site Drainage Area # 1 -2.08 ac. and On -Site Drainage Area #2-0.79 acres). On -site Drainage area # I currently drams to the rear of the site via an existing man- made ditch. On -site Drainage area # I drains to Off -site Drainage area #2 via the same existing ditch through the adjacent site to the southern most property line to Point A as shown on the map. On -site Drainage Area #2 drains to the existing roadway channel along NC Highway 70 and Pinrer5 Point Road and continues along the roadway channel south of the 51te. In order to provide an analysis for any increase of stormwater to the adjacent parcel located east of the site we have also included a pre -developed Off -site Drainage Area #4 for comparison to the post - developed condition. Therefore the overall analysis relative to the Pre -developed and Post - developed conditions analyzes these three different drainage patterns as summarized below: I ) On -site Drainage area # I and Off -site Drainage Area #2 which drain to Point A. 2) On -site Drainage Area #4 (Po5t-developed DA-2 map) and Off -site Drainage Area #4 which drains to Point B. 3) On -site Drainage Area #3 which drains to the NCDOT right-of-way. Post -developed Drainage Area Map DA-2 depicts the post -developed drainage areas. On -site Drainage Area # I represents the drainage area tributary to the proposed wet detention pond. There is a small area off on -site Area (On -site Drainage Area #2) which does not dram through the pond, however a accounted for in the drainage calculation to Point A along with Off - site Drainage Area #2. Drainage Area #3 Not to Pond, is also a small area not draining through the pond. This drainage area flows into the NCDOT right-of-way; please note this area 15 le55 than the pre -developed condition. There is a small amount of impervious area within this drainage basin which also does not dram to the pond; however the water duality storage volume was designed to accommodate this area and over treat the developed area draining through it. There 15 also a small amount of area (On -site Drainage Area #4) which now drams through Off-51te Drainage Area #4 to Point 5. The intent of this study and management plan is to ensure the post -developed drainage through the adjacent properties to Points A and 5 are equal or less than the pre -developed condition, which is shown in the Overall On and Off -site Drainage Area Evaluation table on the following page. It also the intent to show that the On -site Drainage Area #3 which flows to the NCDOT right-of-way has -also not increased from the Pre -developed to the post -developed condition. The purpose of the On-51te 5ub5urface Drainage System and Pond DA-3 map is relative to the design of the on -site subsurface drainage system and proposed NCDOT driveway pipes. Thts map should not be utilized to compare the overall drainage system since the NCDOT right- of-way was not included in the overall analysis, only the respective on -site drainage areas. e �_� State Employees' Credit Union i ' , OBrienAtkins f NO - - C —.O— .

STORMWATER NARRATIVE STATE EMPLOYEES CREDIT UNION NC HWY 70 / PINNER5 POINT ROAD PARCEL ID # 731 G-09-OG54-98000 TOWN OF BEAUfORT CARTERET COUNTY, NC The proposed project 15 located on a +/- 3.0 acre lot located in the northeast quadrant of the inter5ect1on of NC Hwy.70 and Pmners Point Road. The site is currently covered with a grass mixture and has been left uncut for sometime. Topography 15 fairly flat with elevations ranging from elevation 8 at the front of the property to elevation G along the rear part of the parcel. There 15 currently a small channel running through the middle of the site draining from front to back. This channel has been field verified by ACOE personnel and we have received a Juri5dictiona! Determination Stating that there are no waters of the U5 present on this site. A COPY of this 10/ 1 11201 1 letter 15 enclosed in this report.

This proposed plans call for the development of a +/- G,700 5.f, Credit Union office and associated parking lot. The site will be serviced by Town of Beaufort public water and wastewater collection. The total proposed overall impervious area ss G4, 150 s.f. or approximately 54.9% of the total site area. Due to the existing 51te grade con5traint5 not all of the impervious area has been routed to the stormwater wet pond. Approximately 0.09 acres of impervious area will drain along the NC Hwy.70 and Pmners Point Road ditch line. The proposed site plan will provide for an overall stormwater management plan that includes wet pond surface detention to detain the increase storm water runoff. There will be an enclosed storm drainage system which will empty into the pond forebay. The storm water de51gn 15 High Density Commercial, Coastal Storm water regulations. Since the wet pond is located within �/2 mile of 5A Waters the pond has been designed to capture the difference from the pre -developed runoff��,�`� volume and post -developed runoff volume and slowly release it over a 2-5 day time period. The p wet pond has also been designed for 90% T55 removal. There is no off -site runoff coming onto 3�1 the site or into the proposed BMP. In addition, the project does not have buffer requirements and the project 15 not located within a buffer. The flow leaving the stormwater wet pond has been routed to the existing natural channel and released at or below the pre -developed Q- 1 24 hour storm peak rate and Q-10 24 hour storm peak rate. Please find a summary of pre -developed conditions compared with the post - developed conditions on the following page. The proposed wet detention basin holds all proposed storm events up to the Q- 100 while providing I ' of free board minimum. The permanent wet pond will be utilized as temporary erosion control measure (riser basin). Temporary diversion berms/ditches will convey runoff to the riser basin. Please refer to Pre -developed Drainage Area Map DA- I for the pre -developed drainage patterns leaving the site.

On -site Drainage area # I currently drains to the rear of the 51te via an existing man- made ditch. On -site Drainage area # I drams to Off -site Drainage area #2 via the same existing ditch through the adjacent site to the southern most property line to Point A a5 shown on the map. On -site Drainage Area #2 drains to the existing roadway channel along NC Highway 70 and Pinners Point Road and continues along the roadway channel south of the site. In order to provide an analysis for any increase of 5tormwater to the adjacent parcel located east of the site we have also included a pre -developed Off -site Drainage Area #4 for comparison to the post - developed condition. Therefore the overall anaiysis relative to the Pre -developed and Post - developed conditions analyzes these three different drainage patterns as summarized below: I ) On -site Drainage area # I and Off -site Drainage Area #2 which drain to Point A. 2) On -site Drainage Area #4 (Post-deveioped DA-2 map) and Off -site Drainage Area #4 which drains to Point B. 3) On -site Drainage Area #3 which drains to the NCDOT right-of-way. Post -developed Drainage Area Map DA-2 depicts the post -developed drainage areas. On -site Drainage Area # I represents the drainage area tributary to the proposed wet detention pond. There is a small area off on-51te Area (On -Sete Drainage Area #2) which does not drain through the pond, however is accounted for in the drainage calculation to Point A along with Off - site Drainage Area #2. Drainage Area #3 Not to Pond, 15 also a small area not draining through the pond. This drainage area flows into the NCDOT right-of-way; please note this area 15 less than the pre -developed condition. There 15 a small amount of impervious area within this drainage basin which also does not drain to the pond; however the water quality storage volume was de51gned to accommodate this area and over treat the developed area draining through it. There is also a small amount of area (On -site Drainage Area #4) which now drams through Off -site Drainage Area #4 to Point B. The intent of tN5 study and management plan 15 to ensure the post -developed drainage through the adjacent properties to Points A and B are equal or less than the pre -developed condition, which 15 shown in the Overali On and Off -site Drainage Area Evaluation table on the following page. It also the intent to show that the On-51te Drainage Area #3 which flows to the NCDOT right-of-way has also not increased from the Pre -developed to the post -developed condition. The purpose of the On -site Subsurface Drainage System and Pond DA-3 map is relative to the design of the on -site subsurface drainage system and proposed NCDOT driveway pipes. This map should not be utilized to compare the overall drainage system since the NCDOT right- of-way was not included in the overall analysis, only the respective on -site drainage areas. - .Zl NOV 2 9 Z011 13Y,: APlease consider the environment before printing this e-mail.

I talked with Kelly Johnson (who has been trying to finalize guidance for projects within % mi of and draining to SA waters) and she did confirm that a secondary BMP (not just a LS/VFS) is necessary for projects that propose using an 85% pond. The reasoning behind this is that these ponds already, by definition of an 85% pond, need a LS/VFS. So essentially, the discharge from an 85% pond must be directed to a secondary BMP, which then must go to a LS/VFS. Needless to say, a 90% pond would make things a lot simpler. I am attaching the draft guidance I referred to in the meeting yesterday. Please note that this guidance has not -yet been approved and I am only providing it in hopes that it may help you interpret the requirements of the Session Law. If you wish to be a part of the work group that Kelly is working with to finalize the guidance, feel free to contact her at kelly.p.iohnson@ncdenr.Rov. Please let me know if you have any questions.

What I was trying to imply is that the ENTIRE Low density supplement isn't needed if no swales are proposed on the commercial lot. The only form needed at that point is the application. The table on page 3 of the application is sufficient to show that the site meets the low density Christine Email correspondence to and from this address is subject to the North Carolina Public Records Low and may be disclosed to third parties unless the content is exempt by statute or other regulation.

We are wrapping up obtaining signatures from adjacent land owner relative to the Low Density Permit application for their Parcel. Based upon your previous correspondence it sounds as if there are no proposed swales all we need to submit is the Low Density application with no O&Ks. I have attached a pdf and circled in red the area of pavement which will sheet drain across the ground. We did modify the driveway slope connection to 10%. There is a very small amount of drainage which will be directed and sheet drain to this location. If you could confirm this is correct, it would be greatly appreciated. We hope to be calling early next week to schedule the express review.

You will notice that the Low Density supplement now has that same swale table. For commercial sites that meet the LD requirements, a low density supplement isn't needed unless swales are proposed. If swales are proposed, I suggest that it is easier to fill out the low density supplement w/ 0&M to identify those swales than it is to fill out separate grass swale supplements for each.

I have re -graded the pond slightly to obtain the 3.27 feet average depth which allows us to utilize the 3.5 depth relative to the SA/DA for the pond. So, I am able to design the wet pond for the 90% TSS with the engineered level spreader as we reviewed the other day, so it appears we have that aspect worked out. I'm also pulling together a low density permit for the adjacent property as we discussed and wanted to obtain some clarifications relative to the requirements for this application. In reading through the requirements it appears that a low density supplement is not required since the project does not propose to subdivide and sell lots — correct? Are there any other supplements required, I thought there used to be a curb outlet supplement, since we have proposed cub and gutter along the entrance drive which is located on the adjacent property. Please advise what information or requirements there are for the low density permit for the adjacent property. Thanks for all your help!
