EERRecommendation and Conclusion
The Conoconnara Swamp Site `has completed 5 years of stream; vegetation, and hydrologic
success assessments. The stream and vegetation within the site havefperformed well and have
met the,success criteria as defined in the;mitigationplan.
The wetlands have shown a strong progression towards meeting and exceeding the targeted
success criteria,of 7 %,of the growing season. The majority of gauges have shown hydrologic
success for at leasY,2 growing seasons with evidencebf a trend,towards3success'in earlier years.
Based upon, our review and knowledge of the site, EEP recommends'proceeding',to closeout with
the Conoconnara_Swamp site with a,contingency of EBX collecting the hydrologicAata'.for 2012
and providing a report of its findings'to EEP. If hydrologic success is achieved early in the
,growing season, the report may be submitted prior to the end of the growing season: These
findings will be, provided 4o the,IRT for either final closure or, if hydrologic success is not
achieved further recommendations from the IRT.
Contingencies
EEP recommends And EBX,has agreed to monitor the hydrology of wetland gauges during the
2012 growing season and provide a report of its findings to EEP for submittal to the IRT. If
hydrologic success is achieved, EEP will request final closure of the site from the IRT. If
hydrologic success is not achieved, EEP in conjunction with EBX will- provide written
recommendations to the IRT for'resolution of remaining,assets.

APPENDIX A - WATERSHED PLANNING
92226 — Conoconnara Swamp
The Conoconnara Swamp project is located in HUC 03010107090020, the Lower Conoconnara
Swamp watershed, and is listed as a Targeted Local Watershed (TLW) in the 2009 Roanoke
RBRP. Approximately 55% of the streams in this watershed lacks adequate functioning riparian
buffers. Nearly two -thirds of the land here is agricultural including 3 permitted livestock
operations. There are no additional known restoration or enhancement projects in this TLW, but
there are significant conservation lands here.
According to the Roanoke RBRP (2909), "land use tends to be predominantly agricultural
outside of the small townships. A significant amount of landexists in conservation areas
preserved by the Nature Conservancy, the NC Wildlife Resources Commission, and the US Fish
and Wildlife Service. The NC Natural Heritage Program has designated much of the lower
Roanoke as Significant Natural Heritage Areas. As such, EEP recognizes a primary goal for this
CU must be to develop preservation and restoration projects that augment existing conservation
areas or connect them via corridors." This project contributes to the TLW goal of restoring
hydrologic function (onsite stream, floodplain, and wetland flood storage), restoring and/or
protecting significant wildlife habitat, and reestablishing forested buffers in the riparian zone. It
includes 5,050 linear feet of stream restoration and 69 acres of nonriparian wetland restoration,
eight acres of nonriparian enhancement 1, and 71 acres of preservation.
