I propose meeting at 11 am to allow for travel time and to take advantage of some warmer temperatures. The site is very easily accessed off of I-95. Take exit 19 (Carthage Rd.) and take a right at the top of the ramp (if coming from Raleigh; a left if coming from the south). Very quickly, maybe 500-700 feet, you will pull over on the right before the bridge that crosses the canal. My cell phone number is 919-218-1126 if you have any problems. Below is a transcript of some of the earlier discussions on the site. I will bring some handouts with baseline information about the site. Looking forward to seeing you all there. Let me know if we can expect you and please invite others that may be interested in attending. Regards, Tracy Morris Marc Recktenwald wrote: Thanks to everyone for responding quickly. The issue regarding this project isn't mearly the amount of credit and ratios, it is the type. I think John was touching on this in his response. The DWQ rules state (John correct me if I am wrong) that wetland impacts must be mitigated with wetland restoration or enhancement, while the wetland temporal loss can be made up by preservation or enhancement. In the EEP programmatic approach we address this as wetland restoration for the 1:1 and wetland equivalent for the 2:1. Obviously, that distinction can mean a lot in the programmatic approach. For example, we may have a large preservation site that would cover all the equivalents but non of the restoration and therefore enhancement or preservation in 1 of6 1/16/2008 8:02 AM [Fwd: Re: [Fwd: RE: Meadowbranch wetland project; Robeson County]] that particular CU can not be pursued at that time no matter if it is affordable or not. I think that what John and Mickey are saying is that functional uplift may be applicable to the 1:1 component, which of course we would find favorable. We believe that we would be restoring the function of the wetland and therefore would like to recieve credit in the restoration category. I believe we are all on the same page but may not have all the tools in place yet. This may make a good test case. It certainly will give me a better understanding of everything if nothing else and so I look forward to our meeting at the site. Thanks. marc Tracy Morris wrote: -------- Original Message -------- Subject:RE: Meadowbranch wetland project; Robeson County Date:Tue, 27 Nov 2007 08:47:36 -0500 From:Sugg, Mickey T SAW <Mickey.T.Sugg(-,saw02.usace.army. mil> To:Tracy Morris <Tracy.Morrisnncmail.net> CC:John Dorney <john.domcy(a)ncmail.net> References: <474B334B.30304(a?ncmai l.net> Ms. Tracy I would agree with John that for the sake of credit discussion, it would be considered enhancement. However, you are proposing to restore a (major) function of that wetland area; and if that is clearly demonstrated, ratios in the COE permitting process can be adjusted if functional replacement is occurring. For example, if someone is impacting similar wetland types and the impacted wetland scores functionally low (NCWAM) for whatever reason, the amount of compensation that will be required should reflect the functional replacement coming out of Meadowbranch, which would be < 1:2. With the implementation of NCWAM, permit mitigation will hopefully be driven by clearly demonstrated functional replacement, and not ratios. Have a great day, -Mickey -----Original Message----- From: Tracy Morris [mailto:Tracy.MorrisCncmail.net] Sent: Monday, November 26, 2007 3:58 PM To: Sugg, Mickey T SAW; John Dorney Subject: Meadowbranch wetland project; Robeson County Hey John, Mickey: I am interested in hearing your take on a project that I know Mickey has been out to once. It involves restoring a more natural flooding regime to an area that is already a jurisdictional wetland. There is a drainage district maintenance road between the wetland and the (3rd order) stream that must remain in place. We are hoping to put a series of dips in the road to allow flooding to reach the wetlands much more often. Right now they are mainly precipitation fed (except for very large storms). We are not planting the site because most of it was timbered around 15 2 of6 1/16/2008 8:02 AM [Fwd: Re: [Fwd: RE: Meadowbranch wetland project; Robeson County]] years ago and some of the trees are of a decent size. We don't want to bush hog the site and start all over. We hope the more natural flooding regime will help weed out some of the less appropriate species for this landscape position. Our internal discussion revolves around whether to call this project enhancement or restoration. By the books, it is clearly enhancement. But functionally, I can understand wanting to claim that restoring a more natural flood regime will really restore the riparian wetland functions of the site. I'm happy to take you out to the site, which is very easily accessed, about 80 minutes from Raleigh and about 300 yards from I-95 in Lumberton. The project really presents an awesome opportunity for water quality uplift in the area. If we were to call the project restoration, though, we would need to have concurrence from both of your organizations in writing, I am told. I'll attach a photo. Please let me know if I can arrange a site visit or an office meeting to review the draft plans. Thanks so much for your time, gentlemen. Hope you enjoyed your Thanksgiving break.

Sediment deposition is not excessive, but at approximately natural levels. ?B Sediment deposition is excessive, but not overwhelming the wetland. ?C Sediment deposition is excessive and is overwhelming the wetland. 11. Wetland Size - wetland type/wetland complex condition metric Check a box in each column. Involves a GIS effort with field adjustment. This metric evaluates three aspects of the wetland area: the size of the wetland type (WT), the size of the contiguous wetland complex (WC), and the size of the contiguous, forested wetland (FW) (if applicable, see User Manual). Boundaries are formed by uplands, four-lane roads, or urban landscapes. An observed beaver pond forms a boundary if it extends across the entire width of the floodplain. Additionally, other wetland types are considered boundaries for column WT. If assessment area is clear-cut, select "K" for FW column.

Connectivity to Other Natural Areas - landscape condition metric Check appropriate box(es) (a box may be checked in each column). This metric evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous naturally vegetated area and open water (if appropriate). Boundaries are formed by four-lane roads, urban landscapes, maintained fields (pasture and agriculture), or open water > 300 feet wide.

(evaluate for marshes only) ?Yes o Does the assessment area experience overbank or overland flooding during normal rainfall conditions? 14. Edge Effect - wetland type condition metric Estimate distance from wetland type boundary to artificial edges. Artificial edges include permanent features such as fields, development, two-lane or larger roads (2 40-feet wide), utility line corridors wider than a two-lane road, and clear-cuts < 10 years old. Consider the eight maj) points of the compass. A No artificial edge within 150 feet in all directions ?B No artificial edge within 150 feet in four to seven directions ?C An artificial edge occurs within 150 feet in more than four directions or assessment area is clear-cut 15. Vegetative Composition - assessment area condition metric (skip for all marshes and Pine Flat) &?A Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate species, with exotic plants absent or sparse within the assessment area. ?B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing. It also includes communities with exotics present, but not dominant, over a large portion of the expected strata. ?C Vegetation severely altered from reference in composition. Expected strata are unnaturally absent or dominated by exotic species or composed of planted stands of non-characteristic species or inappropriately composed of a single species. 16. Vegetative Diversity - assessment area condition metric (evaluate for Non-tidal Freshwater Marsh only) ?A Vegetation diversity is high and is composed primarily of native species (< 10% cover of exotics). ?B Vegetation diversity is low or has > 10% to 50% cover of exotics. ?C Vegetation is dominated by exotic species (> 50 % cover of exotics).
