We have been working on it, just don't have a resolution just yet. Our client is looking at mitigation for this at around $160,000 based on the credit reservation letter. We didn't recall ever being required to pay mitigation when we were under 150 linear feet of stream disturbance, so we are trying to find ways to lessen the impacts here and to reduce this expense. Any suggestions you would have on that would be appreciated. Regarding the 15 days, do you mean 15 days to respond from when your email came out yesterday? Regarding the SHPO and the house: I have attached pics on this that the clearing contractor took months back, but the guys clearing the site demoed that house months back before we were even told there was a potential house on the site. We didn't know is was there. Clearing guys said that it was dilapidated/caving-in and couldn't safely access. We can't provide the requested further documentation from the SHPO because we don't know how many floors, rooms, windows, doors, etc., there were in the house, as no one went in. Also, based on these pics I'm not sure if it would have been possible to move it.

In many coastal areas mitigation is charged for impacts to coastal stream for impacts over 25' feet. The ratio can be negotiated based on the quality of the stream and that is why I asked about a NC Stream Assessment Form. In the Wilmington District we do not consider the bottom of the stream to be a wetland. Mitigation is done on a linear footage impact and mitigation banks have stream mitigation credits. Please refer to the 2008 mitigation rule under which the three mechanisms for providing compensatory mitigation which in order of preference is mitigation banks, in -lieu fee programs, and then we consider permittee-responsible mitigation. If your applicant wants to consider putting in a bridge feature or reducing the crossing impact significantly your proposal will still likely require mitigation. There are a couple banks located in Onslow County within the watershed of this proposed development that likely have the required credits available.

We have done a bunch of stream crossings over the years, most times with the bottoms of the stream being considered wetlands, and then sometimes Riparian Buffers credits, etc. We have had to do mitigation on a square foot basis when it exceeded 0.10 ac and have done that via mitigation, in -lieu, conservation easement, or a combination of the three. However, we can't offhand remember a time when we were required to do mitigation on a linear foot of stream basis. So my question then is..... what threshold level are we exceeding that is causing the mitigation to be required on this site? I ask because I have no idea yet how costly this is going to be for our client, and if there is something we can do design wise to get under the threshold level or lessen the impacts, I may need to do that.

He was looking for the origin of the stream and was not looking at the location of the crossing that I was discussing. There is a North Carolina Stream Assessment form that uses methodology developed by the State and consulting groups on how to rate the quality and type of the stream resource. The State also has their own stream assessment forms, but what you provided is not either of those assessments. Based on the type of resource impacted (perennial stream) a conservation easement would not be adequate as you do not have additional streams onsite to preserve. Any other impacts to those streams would require a permit and thus the threat to the resource is limited. It is also out of line with our mitigation rule which is first to go to an established mitigation bank, then discuss in -lieu fee, and then conservation easement. The Corps has found that conservation easements are often violated and do not have the success rate as mitigation banks. Mitigation will be required for that crossing at a 2:1 ratio. Also please be aware that this permit is currently on hold as I have still not heard from the State Historic Preservation Office on the data point located on -site (appears to be a house). Still waiting on their concurrence and I need that information before I issue this permit. Please let me know if you have any additional questions.

The following revisions have been made to the documents based on comments received. I have added my comments regarding the revisions made in BLUE text below. USACE Comments (Rachel Capito): 1) Provide mitigation for the stream crossing site with a 2:1 ratio. The stream crossing site has been revised to reduce the required impacts to the extent possible. This was accomplished primarily by lowering the roadway profile at the crossing approximately three to four feet, and additionally by steepening the rip -rap protected slopes to that amount acceptable to NCDOT. The combination of these changes net a reduction of 68 linear feet of impacts to the stream crossing. Additionally, the impacts to the 50' vegetated buffers have roughly been cut in half. Please refer to plan sheet 2 for the revised crossing plan and profile. When reviewing please let me know if you have questions. 2) Project on hold until site reviewed and comments received from SHPO regarding the Horace Grant house. Per previous email correspondence, I have forwarded pics of the house that the clearing contractor took months back. The clearing contractor site demoed that house months back before we were even told there was a potential house on the 1316-B Commerce Drive.P.0.

Also, based on these pics I'm not sure if it would have been possible to move it. DEMLR Comments (Holley Snider): 1) Letter C La. please clarify that wetlands and streams will be impacted. Wetlands, Streams, and Buffers proposed to impacted. Application checked as such. 2) Letter C 3.a. please clarify the linear feet and width of the perennial (This has been revised to Perennial on the application) (not intermittent) stream to be impacted. The plans indicate 120 linear feet of pipe for the proposed roadway crossing. Additionally, the DWR general water quality certification 4139 is specifically conditioned to state: Culverts shall be designed and installed in such a manner that the original stream profiles are not altered and allow for aquatic life movement during low flows. The dimension, pattern, and profile of the stream above and below a pipe or culvert shall not be modified by widening the stream channel or by reducing the depth of the stream in connection with the construction activity. The width, height, and gradient of a proposed culvert shall be such as to pass the average historical low flow and spring flow without adversely altering flow velocity. [1SA NCAC 02H .0506(b)(2) and (c)(2)] AND If multiple pipes or barrels are required, they shall be designed to mimic the existing stream cross section as closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream channel shall be avoided. The submitted drawings depict a meandering perennial stream 6 feet in width. The proposal depicts two (2) 42" culverts 120 feet in length. The cross-section drawing indicates the pipes would be located outside of the stream channel. Please ensure that your that your project has been designed to meet the conditions above and provide any justification and clarification necessary. Proposed crossing pipes revised from double 42" RCP to double 36" reinforced concrete pipe, buried 8" at both ends for passage. This better fits inside the ditch channel section as located in the field. We feel this best mimics the natural channel and profile. 1316-B Commerce Drive.P.0.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. This is the only planned crossing of the stream for the Windpointe Subdivision project. The blue -line stream extended fully across the project, so it was necessary to cross for project continuation. Fill impacts are those necessary to make the crossing mainly, and additionally for a very small fill for roadway construction bypass point to support lot construction geometry. Note that the stream crossing site impacts have roughly been cut in half since the original application/proposal. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Silt fence and construction fencing will be utilized to isolate the area. A check dam will be installed downstream of the proposed storm drain. Stabilization will be completed as soon as the fill is brought up and slopes/shoulders graded out to plan elevations. Slopes at crossing site will be stabilized with full rip -rap placed on filter fabric. Silt fencing will be maintained daily. 2.
