He disagrees that the SHWT can be found through qualitative estimation based on the ditch location for this site. If you have technical questions about this determination, I would encourage you to talk to Vince, as I do not profess to be an expert in soils. Vince will be in the office today, but then will be on leave or otherwise out of the office for a couple of weeks. Kelly tclinkscales wrote: I again appreciate everyone looking at such To answer your question Linda, enclosed is the data that explains when the data was compiled As far as the information obtained from the site, we use this information as an aid to verify what the soils books tell us and our field observations Also since most if not all of our ponds are very close to our outfalls, the outfall elevation should be able to be used in reasonably establishing the elevation of the seasonal high water table for wet ponds We believe this is the case because if we take the outfall elevation as our permanent pool elevation (PPE) and our ponds are close to our outfall, the seasonal high water table can not be above the existing grade of the outfall, therefore meeting the rules For this site in particular, the ditch was not considered jurisdictional, therefore to be conservative we added 0 5' above the outfall elevation to set our PPE and since the pipe is only 14 feet from the ditch, therefore the PPE that we have established should meet the rules of being at least 6" below the PPE We understand this approach for establishing seasonal high water table is only used for wet ponds and true field data from a soil scientist is needed for any infiltration devices because these systems need both depth and rates to meet the statue law established by the legislature Thanks again and have a good day Tim l of 7 5/8/2009 12 36 PM RE.

We went through the plans, and the soils data provided and he looked at the slope of the land and NRCS soil permeability in relation to the pond's location. The permeability for Norfolk soils is 0.6-2.0 in/hr and the SHWT ranges from 4-6 feet. It was determined that the NRCS information provided is too general to use for establishing the SHWT for the pond's location. Vince offered to discuss this with you if you are interested, 796 7378.

Kelly tclinkscales wrote: We again need a meeting to discuss, this approach is totally against what we have placed in the hands of reviewers in the past and the agreed upon approach. Everyone's attitude about minor changes being redone in 24 hours is very unfortunate, what would happen if someone was out of town, sick, or their email was down, they would have no way to check such and resubmit in the time required. On this one, I did see the comments, but I do have meetings, other projects and such and would expect more than one day to resubmit. I understand we always seem to come back to the same place with all of my reviews but I am only following the standard that has been placed in front of me on past projects and logical engineering judgment. Does the department understand or even care about the prices that are associated with the kind of information you are requesting. Our designs take into account protecting the environment but using sound logic. I can rant and rave for pages on pages but the bottom line is, developers are continueing to be hammered by more and more costs, this is another project where the developer wants to start the project, create tax revenue, jobs for his practice, and jobs for all the workers who build the infrastructure. I understand this is not the reason to permit the design given, but it meets the intent of the rules, it is not to say it is perfect and comments may be needed to clarify things but the intent of the design is sound and within the regulations of your rules and sound engineering judgment. I again am getting something sent back to our client for such, I can not say I have been patient but we have discussed such in the past and meets your internal policies and the statute law.

I understand that the current application based the SHWT on field observation and NRCS soil 3 of 7 5/8/2009 12 36 PM RE, Dr Kenyon's Office, State Stormwater Permit c information in combination with the elevation of a ditch located at the back of the property. However, the elevation of the SHWT must be determined through soil indicators found through site specific testing. Also, I appreciate the email yesterday containing the sidewalk and curb details and a note that the "no wetlands on site" note would be added. Perhaps I should clarify for future submittals that the intention of the completeness review is to identify and acquire information that was either omitted from the package or to correct small issues that can be handled "quickly" within about 24 hours. These items should be submitted in a complete form, meaning that plans should be stamped/sealed and and notes requested should be added (as opposed to providing an email that they would be added in the future). I typically work with people if they need the day to make the small changes and then need time to drop it off the following day, but I do need the finished product in hand "quickly" so that we can accept it into the review process and it can be assigned to an engineer. Unfortunately, due to the need for SHWT data I will have to return the application. The attached letter will be mailed today. Kelly tclinkscales wrote Kelly, In response to your comments from below. 1. Based on previous meetings with Linda/Mary Jeane, the seasonal high water table for ponds can be based on field observation and or soils information, without the need for a soils scientist to obtain in soil borings or prepare a report for such. We choose our permanent based on the outfall elevation at the northwest corner of the property being around elevation 39.5. Since the ditch in the back of the property was not determined to be jurisdiction and during our site visit was empty, we have taken the seasonal high water table to be a maximum of 6 inches above the bottom of the ditch, at elevation 40. We believe this is a conservative value since the soils map says for Norfolk type soils the depth to high water table is greater than 6 feet. 2. Enclosed is the detail for both the sidewalk and curb 3. A note will be added to the note page that reflects such. 4 of 7 5/8/2009 12 36 PM RE Dr Kenyon's Office, State Stormwater Permit Please let me know of any additional information you may need and if required can provide you the updated sheets as requested.

I have a few questions for you: 1.) SHWT. The supplement says that both the permanent pool and the SHWT are at 40fmsl, but I do not see any soils information discussing SHWT. Can you send me that? (Also, FYI, the Central Office has now published more SHWT guidance, h_ttp://h2o.enr.state.nc.us/su/documents/PondSHWT Original pdf.) 2.) Details: Can you send me any associated details such as the sidewalk and curbing? 3.) Wetlands: I see the letter from Donald Beale about the preliminary 404 determination and that the site has uplands, but I need to see "no wetlands on site,, on the plans. Is there such a statement on the 5 of 7 5/8/2009 12.36 PM RE- Dr. Kenyon's Office, State Stormwater Permit plans already? I don't see it, but there is a lot of information so maybe I am missing it You probably already know that we do two levels of review for each project. When we first receive it we go through it to make sure we have everything, which we call the "completeness review". If we are missing any information, we request that we receive it within 24 hours. If we are not able to obtain the information within 24 hours we return the application. If all of the data is received, we accept the project and it is assigned to a review engineer for the technical review. These are fairly minor items that were probably just inadvertently omitted. Can you provide these three items within 24 hours?

The project is located at 2298 Ocean Highway inside the Town of Shallotte The site currently drains to a tributary of Williams Branch (SC; SW;HQW), and according to the NRCS Soil Survey of Brunswick County the soil across the site consists of Norfolk Loamy Fine Sand (NoB), and the ground cover on the parcel consists of sparse grasslands The proposed facility will consist of three buildings and associated parking areas as illustrated on the plans. The project will be performed in two phases, the first phase will consist of one building and associated parking In this phase, stormwater runoff will conveyed by sheet flow to a proposed Swale at the end of phase I into a wet detention pond. For the second phase, stormwater runoff will be conveyed by a storm sewer system the wet detention pond where it will then be treated and stored per NCDENR and Town of Shallotte stormwater regulations The pond will be designed and constructed for full build -out in phase I of the project. All supporting drainage calculations, drainage basin and swale information are provided within the following pages of this report Page 1 I MAINTENANCE Contractors shall be responsible for periodic inspection and maintenance of all indicated erosion control devices In addition, inspection and any necessary maintenance will be required immediately following any significant storm event Any erosion control measure that fails to function as intended shall be repaired immediately Upon completion of construction and the establishment of stabilized ground cover, the property owner shall be responsible for any on going site maintenance EROSION AND SEDIMENTATION CONTROL SPECIFICATION PART1-GENERAL 11 RELATED DOCUMENT A.

Description — Hydrologic Soil Group Q Advanced Options Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly Aggregation Dominant Condition wet, and receive precipitation from long -duration storms. Method I I The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, Component !. and C/D). The groups are defined as follows: Percent Cutoff Tie -break Rule Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist Lower mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of Higher water transmission. ViewDescriptionj.. View Rating 1 Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately j deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately Map Unit Name _. _.._. coarse texture. These soils have a moderate rate of water transmission. Parent Material Name Representative Slope Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. Unified Soil Classification (Surface) These soils have a slow rate of water transmission. Water Features �IQ Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned '... ''.. to dual classes. Rating Options — Hydrologic Soil Group Ci*.

Suite 201 Wilmington, NC 28403 RE Preliminary 404 Wetland Evaluation — 2298 Hwy 17 Dear Mr. Chnkscales Per your direction, Land Management Group, Inc. (LMG) conducted a preliminary 404 wetland evaluation of the approximately --1.5 acre parcel located at 2298 1lwy 17 in Brunswick County, NC. Our work included an assessment of available maps (county soil survey, USGS topographic quadrangle, etc ) and aerial photographs LMG staff visited the site on January 16, 2009 Our on -site evaluations included limited assessments of the three parameters (sods, hydrology, and vegetation) that identify the limas of Jurisdictional wetlands as defined in the 1987 Corps of Engineers (COE) Wetland Delineation Manual. The following is a summary of our findings. Based upon observations noted at the time of our field evaluation, it is our opinion that the site is entirely uplands The site consists of sandy soil series (Norfolk) that is well drained and vegetation that is characteristic of uplands The ditch that runs along the northern property line does not exibit any characteristics of an RPW (relatively permanent waters) and should not be Jurisdictional. I hope this information is of assistance for your work I may be reached either by phone at 910.452.0001 or by email at dhealeui InrgnmP nci should you have any questions.
