Martin, PWS Regulatory Specialist U.S.Army Corps of Engineers CE-SAW-RG-R 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 Zach Thomas Environmental Program Consultant Division of Water Resources Raleigh Regional Office Raleigh, NC 27699-1628 Matt & Zach In response to your letter,January 25, 2024' for the permit non-compliance for Everwood S/D SAW-2019-00882 I have taken several steps to help bring this site into compliance. These steps include visiting the site, discussions with the construction personnel, and reviewing these violations with the owners. Steel Bridge Crossing is determined to bring this site into compliance with the 401 and 404 permits. The following is a list to list the non-compliance items in your letter along with an answer for each non-compliance statement. A simple restoration plan will be included in the answer to item #3. The problem areas have already been noted by you in your earlier inspection so I will not provide a map with this response. 1) "Regional Condition 9: Installation of culverts in wetlands shall ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. For all NWPs that involve the construction/installation of culverts, measures shall be included in the construction/installation that will promote the safe passage of fish and other aquatic organisms. -The culvert installation on the recent extension of Mahogany Way appears to be installed suspended over the wetland." I agree the culvert outlet is perched and needs correction. I have discussed this with Curk Lane, PLS the surveyor for this project and Jerry Dalton, PE the design engineer. I've discovered the construction plans have been revised since the 401 and 404 permits were issued. The cul-de-sac for Mahogany Way has been extended to the south but also moved to the east. This easterly move has avoided the existing wetland and avoided the approved wetland impact#3 on the permit. The outlet of the culvert does not flow directly into the wetland. I have attached an enlargement of the construction plans showing the wetland impact being avoided. In order to be confident,the wetland had been avoided,we had the surveyor flag the original top of my wetland. I did not measure it but it was approximately 8-10 feet downstream from the outlet of the perched culvert. The perched culvert must still be repaired and the existing downstream wetland must be protected during this repair. 2) "Regional Condition 17: All PCNs will identify and describe sedimentation and erosion control structures and measures proposed for placement in waters of the U.S. The structures and measures should be depicted on maps, surveys or drawings showing location and impacts to jurisdictional wetlands and streams. -There are several sediment and erosion control structures and measures placed within waters of U.S. that were not disclosed in the PCN, these were observed at impact areas 1 and 3. The sediment structure located downstream of the perched culvert, in the vicinity of the impact 3, is actually located just above the top of the original delineated wetland. When the surveyor marked the wetland in the field for us, it proved the temporary sediment structure is located out of the wetland. The temporary sediment structure located in the wetland at impact area 1 will be removed and the disturbed area in the wetland returned to its existing elevation and also seeded with a wetland seed mix. 3) "Unauthorized discharges of dredged and fill material were identified in and around impact area 3. There was sediment deposited in the wetland located below the perched culvert of impact#3. The contractor temporarily placed wooden board in the wetland to roll wheelbarrows on, so not to rut up or damage the wetland. They have used flat bottom shovels and short tooth rakes to remove the sediment from the wetland downstream. They removed the sediment from the downstream areas as far as it was found. They took care not to disturb the original natural ground with the flat bottom shovels by leaving approximately no more than 1 inch of sediment depth in the wetland areas. As they went out of the wetland, they removed the boards so as not to cause any more damage. The contractor will purchase a typical wetland seed mix from Green Resources in Garner. It will be broadcast at 20 to 25 lbs. per acre (1 lb./2000 sq.ft.). After the restoration work is complete, I will reinspect all the areas of non-compliance to ensure the problem areas have been resolved and send you pictures. I appreciate your time you have spent on this problem and apologize for the area being in non- compliance with the permit. If you have any questions or concerns, please don't hesitate to contact me.
