Executive Summary The Haws Run Mitigation Site is located on the Pender-Onslow County line approximately 28 miles northeast of Wilmington, North Carolina. The Haws Run Mitigation Site was designed to provide compensatory mitigation for unavoidable impacts to wetlands in the nearby area, TIP Number R-2405WM. The site consists of riverine swamp forests on the north and south ends and an interior of former wet flats and savannahs. Hydrology was altered by a central canal and lateral ditches. The mitigation site is approximately 348 acres in size. It is composed of two areas for restoration and/or enhancement, the savannah and the swamp forest. Construction began in summer 1998 by the excavation of the site to designed elevation and the filling/plugging of the central canal and the lateral ditches. The site was planted in early spring 1999 and completed in spring 2000. Reliability of the monitoring wells was the greatest problem. BLWI was not provided with sufficient information to start collecting well data until August, 2005. Some of the wells were malfunctioning and provided inconsistent data. Data was not collected from all of the wells originally installed after project construction. The 2004 monitoring report considered the site a success in meeting both vegetative and hydrologic criteria. The monitoring year 2005 was year 6 for hydrologic monitoring and year 7 for vegetative monitoring. One plot in the savannah and two plots in the swamp forest area did not meet the success criteria. Four of the twelve ground water monitoring wells downloaded did not attain the 12.5% wetland status.

Project Condition and Monitoring Results a. Vegetation Assessment i. Soil Data According to the NRCS soil survey for Pender and Onslow counties, there are 6 main soil series within the mitigation site. They are Foreston, Grifton, Muckelee, Stallings, Torhunta and Woodington. Foreston, Torhunta and Woodington appear to be the dominant types. The soils present are either fine sandy loam, loamy fine sand or loam in nature. Table VI.

iv. Success Criteria (Savannah Areas) The savannah areas will meet the success criteria once there is a minimum of 20 trees/acre survive for five consecutive years. v. Success Criteria (Swamp Forest Area) Planting success will be achieved if a 320-stem count/acre survival for the first three years is met. Afterwards, survival can decrease by 10% for each year over the next two years to where the stem count could be 260/acre at monitoring year 5. No one species can exceed 20% of the total number of species planted. vi. Stem Counts (Savannah Area) A total of three sample plots were established – two in Zone 1, the wet savannah restoration and enhancement areas and one in Zone 2, the dry savannah enhancement area. Pinus palustris, longleaf pine, Pinus serotina, pond pine and Taxodium ascendens, pond cypress was planted in Zone 1. Only Pinus palustris, longleaf pine was planted in Zone 2. All plots were 500’ X 500’ in size.

b. Wetland Assessment and Recommendations i. Wetland Problem Areas Plan View (see Figure 4) Reliability of the monitoring wells was the greatest problem. Blue was not provided with sufficient information (access to site) to start collecting well data until August, 2005. Some of the wells appeared to be malfunctioning. Data was not collected from all of the wells installed after construction. ii. Wetland Criteria Attainment Wetland criteria were met if the hydrologic regime was maintained for 12.5% of the growing season. The 2004 monitoring report considered the site a success in meeting both vegetative and hydrologic criteria. Of the twelve monitoring wells that were able to be downloaded at the end of the 2005 monitoring period, four, HR-7, HR-22, HR-23 and HR-24, did not attain this criteria. The year 2005 was relatively dry with January, February, March and July being below the 30-70% rainfall percentile. High rainfall in September and October was the result of hurricane Ophelia and tropical storms. The surface water gauge only showed increased standing water during the October event.

Executive Summary The Haws Run Mitigation Site is located on the Pender-Onslow County line approximately 28 miles northeast of Wilmington, North Carolina. The Haws Run Mitigation Site was designed to provide compensatory mitigation for unavoidable impacts to wetlands in the nearby area, TIP Number R-2405WM. The site consists of riverine swamp forests on the north and south ends and an interior of former wet flats and savannahs. Hydrology was altered by a central canal and lateral ditches. The mitigation site is approximately 348 acres in size. It is composed of two areas for restoration and/or enhancement, the savannah and the swamp forest. Construction began in summer 1998 by the excavation of the site to designed elevation and the filling/plugging of the central canal and the lateral ditches. The site was planted in early spring 1999 and completed in spring 2000. Reliability of the monitoring wells was the greatest problem. BLWI was not provided with sufficient information to start collecting well data until August, 2005. Some of the wells were malfunctioning and provided inconsistent data. Data was not collected from all of the wells originally installed after project construction. The 2004 monitoring report considered the site a success in meeting both vegetative and hydrologic criteria. The monitoring year 2005 was year 6 for hydrologic monitoring and year 7 for vegetative monitoring. One plot in the savannah and two plots in the swamp forest area did not meet the success criteria. Four of the twelve ground water monitoring wells downloaded did not attain the 12.5% wetland status.

Project Condition and Monitoring Results a. Vegetation Assessment i. Soil Data According to the NRCS soil survey for Pender and Onslow counties, there are 6 main soil series within the mitigation site. They are Foreston, Grifton, Muckelee, Stallings, Torhunta and Woodington. Foreston, Torhunta and Woodington appear to be the dominant types. The soils present are either fine sandy loam, loamy fine sand or loam in nature. Table VI.

iv. Success Criteria (Savannah Areas) The savannah areas will meet the success criteria once there is a minimum of 20 trees/acre survive for five consecutive years. v. Success Criteria (Swamp Forest Area) Planting success will be achieved if a 320-stem count/acre survival for the first three years is met. Afterwards, survival can decrease by 10% for each year over the next two years to where the stem count could be 260/acre at monitoring year 5. No one species can exceed 20% of the total number of species planted. vi. Stem Counts (Savannah Area) A total of three sample plots were established – two in Zone 1, the wet savannah restoration and enhancement areas and one in Zone 2, the dry savannah enhancement area. Pinus palustris, longleaf pine, Pinus serotina, pond pine and Taxodium ascendens, pond cypress was planted in Zone 1. Only Pinus palustris, longleaf pine was planted in Zone 2. All plots were 500’ X 500’ in size.

b. Wetland Assessment and Recommendations i. Wetland Problem Areas Plan View (see Figure 4) Reliability of the monitoring wells was the greatest problem. Blue was not provided with sufficient information (access to site) to start collecting well data until August, 2005. Some of the wells appeared to be malfunctioning. Data was not collected from all of the wells installed after construction. ii. Wetland Criteria Attainment Wetland criteria were met if the hydrologic regime was maintained for 12.5% of the growing season. The 2004 monitoring report considered the site a success in meeting both vegetative and hydrologic criteria. Of the twelve monitoring wells that were able to be downloaded at the end of the 2005 monitoring period, four, HR-7, HR-22, HR-23 and HR-24, did not attain this criteria. The year 2005 was relatively dry with January, February, March and July being below the 30-70% rainfall percentile. High rainfall in September and October was the result of hurricane Ophelia and tropical storms. The surface water gauge only showed increased standing water during the October event.
