General information concerning each project is as follows: 1. Area K wetland related improvements involve the restoration of a bridge over McPherson Creek. Vehicles at ..present, travel through the stream bed, causing obvious problems with sediment and turbidity. A dilapidated wooden bridge structure will be restored and include stabilized approaches, greatly decreasing Mr. John Dorney Page 2 February 5, 1992 the in-stream sediment load. Also in Area K, basin is to be constructed at the bottom of a currently discharging heavy sediment loads into of McKellar's Lake. This basin appears to be o that wetland. a large sediment ravine which is the headwaters n the fringe of' Any negative impact of this project would be of short duration, and long-term benefits far outweigh the negligible area of wetlands lost. It is, therefore, recommended that the appropriate certification be granted. 2. This project involves the construction of a new sewer force main to connect Simmons Army Airfield to the wastewater treatment plant at Fort Bragg. This sewer will be approximately 5 miles long and replace an existing line which has become inadequate with new development on this installation. According to information provided by the Savannah Corps of Engineers, there will be three wetland crossings, one of which is elevated. The other two crossings will be of approximately 100 feet and 950 feet. Assuming this to be accurate, the maximum wetland area to be disturbed will be .327 acre. Disturbed areas will be restored to original contours as construction is completed. This office has no objection to issuance of the appropriate 401 Certification. However, it should be noted that wetlands will be temporarily impacted in the watershed of Cross Creek, a WS-III stream. 3. This project involves the stabilization of a stream bank on hole Nos. 2 and 17 on the Officer's Golf Course at Fort Bragg. Banks have sloughed off and into the creek due to steep slopes and.are continuing to collapse on up the creek channel. Also included in this package was a request concerning repair, rehabilitation, and replacement of existing culverts on boundary roads at several crossings of minor tributaries in the upper reaches of Bones Creek. This will involve removal of sediment clogging the drains, construction of small wing walls, and/or installation of larger culverts. No single project should disturb or cause impact to more than .1 acre. Comple- tion of these projects will aid in sediment control and prevent loss of trees due to flooding. With these considerations in mind, it is the recommendation of this office that the appropriate certification be granted. Mr. John Dorney Page 3 February 5, 1992 4. Erosion control at Sicily Flight Landing Strip and Drop Zone has been a major concern for some time. This project (which appears to have been assigned two numbers) involves the placement of riprap below the discharge point of a large sediment basin located on the northwest end of the drop zone. Total fill area is estimated to be less than 4,000 sq. feet. The Corps of Engineers, representative visiting this site recommended that a 401 approval be obtained, though there is reasonable doubt that any part of this project is in an actual wetland area. This determination has been made difficult by the tons of sediment deposited in this area over the years. No wetlands of significance will be lost as a result of this project. Therefore, it is the recommendation of this office that the appropriate certification be granted. 5. The south perimeter road project at Simmons Air Field involves culvert installation and/or improvement for two minor road crossings near the new maintenance hangars. Both are considered above headwaters of Cross Creek, class WS-III waters. No4 significant wetland values are known to exist at either site. Total fill for both crossings is estimated at approximately .4 acre (12,000 sq. feet and 6,000 sq. feet). It is the recommendation of this office that the appropriate certification be provided for this project. 6. This project involves the replacement of the wooden bridge over Flat Creek (WS-III watershed). The original bridge was destroyed in a wildfire. Fill will involve no more than installation of pilings and bridge abutments, with a very small amount of fill in the approaches. This is a very small, single -lane bridge used mainly for fire control vehicles and some troop training. Total fill should be less than 400 sq. feet. No significant wetland values are known to be associated with this site. It is, therefore, the recommendation of this office that the appropriate certification be granted. Should additional information or clarification be required on any of the above projects, please contact Mr. Ken Averitte at (919) 486-1541. MJN/KA/tf AF7A-DE-D 1 Oct 91 METIORANDUM FOR Commander., U.S. Army Engineer District, Wilmington, ATTPT: CESAW-CO-E (Mr. Mike Smith), P.U. Box 1890, Wilmington, NC 28402-1390 SUBJECT: Energy Dissipation for Sediment Retention Structure rat Sicily Flight. Landing; Strip (FLS), Fort Bragg 1. Reference: Meeting and field site visit by Mr. Mike Smith and TIP. runice Vachtn, at Fort Bragg;, 26 Sep 91, regarding sedimentation control at Sicily FLS. 2. As a follow-up to the meeting and field visit, this memorandum notifies you of Fort Bragg's intent to stabilize the outlet of a sediment retention structure situated northwest of the FLS. Since it is now being redesigned and implemented as a permanent sediment control structure, it is necessary to construct a permanent riprap energy dissipator at the outlet and extend the riprap along the narrow channel created by the seepage emtanating, from this area. This treatment will cover an area less than .99 acre in size. It is under- stood from your meetings with Its. Vachta that this implementation might be covered by the Nationwide 26 permit and, in any event, doers not constitute a wetlands violation. 3. It appears that in recent months the seepage is being sustained at this location even in dry weather, perhaps an a result of the conservation and runoff control measures implemented at the FLS to control erosion and reduce peak flow.. It is our hope that this condition and improved sediment control will enhance the development of a high quality wetland in the downstream area that has been previously affected by sedimentation. 4. The site is indicated on the maps provided in the enclosure. No stream branch is indicated for this looation by the U.S. Geological Survey map. Relief as shown consisted of Bullied areas prior to the construction of the erosion control measures at the site. The Soil Survey of. Cumberland and Hoke Counties, North Carolina, indicates a Blaney loamy sand at 8- to 35- percent slopes and an intermittent drainageway at this location.
