SUMMARY The following report summarizes the monitoring activities that occurred in 2010 at the Mitigation Site on Lot 121 in the Dolphin Ridge Subdivision that was created pursuant to Permit 200200769. The Dolphin Ridge Subdivision is located on the south side of Coast Guard Road in the Town of Emerald Isle. The Town of Emerald Isle is located in Carteret County, North Carolina. The goal of the monitoring activities is to determine if the Mitigation Site has been constructed and planted to establish a sustainable wetlands area ("Created Wetlands") that is similar to the natural wetlands that adjoin the Mitigation Site. The data obtained from the monitoring wells installed in the Mitigation Site and the survival and growth of the various wetlands plants planted in the Mitigation Site indicates that the Mitigation Site is functioning just like the natural wetlands it adjoins and that the creation of the Created Wetlands has been successful. Although one additional year of monitoring is required, based on the results from the first two years of monitoring, the mitigation has been successful and the Mitigation Site is a functioning wetlands. INTRODUCTION Project Description: The Project consists of 4,164.59 square feet of mitigation area on Lot 121 in Dolphin Ridge. The mitigation area is to provide compensatory mitigation for 3,561 square feet of wetlands filled on Lot 113 in Dolphin Ridge. The compensatory mitigation exceeds the minimum 1:1 onsite mitigation ratio. A copy of a portion of the subdivision plat for Dolphin Ridge is included in Exhibit 1 to this Report. The plat has the general location of the Mitigation Site marked on it. The Mitigation Site initially was excavated and planted in 2007. However, the Corps of Engineers expressed concerns that the depth of the 2007 excavation might not be sufficient to establish long term sustainable wetlands. To address these concerns, in 2008 additional excavation occurred at the Mitigation Site to bring the elevation in the Mitigation Site to an elevation similar to that of the natural wetlands that adjoin the Mitigation Site. The Corps of Engineers also recommended that when the Mitigation Site was replanted after the additional excavation that plants from the neighboring natural wetlands be transplanted to the Mitigation Site to insure compatibility and to increase the success of the wetlands. Accordingly, in 2008, the Mitigation Site was planted with a mix of Lizard's Tail (Saururus cernuus), Rush (.luncaceae), Red Maple (Acer rubrum), Button Bush (Cephalanthus occidentalis), Wax Myrtle (Myrica cerifera), Bald Cypress (Taxodium distichum), and Sweetbay Magnolia (Magnolia virginiana) plants. Although not reported previously, Fetterbush (Lyonia lucida) also was transplanted into the Mitigation Sites. We specifically did not plant any Common Cattail (Typha Latifolia) in the Mitigation Site. After the planting was completed, two monitoring wells were 3 installed in the Mitigation Site. The monitoring wells were installed pursuant to the instructions and procedures detailed in the "Technical Standard for Water-Exhibit Monitoring of Potential Wetland Sites" prepared by the U.S. Army Corps of Engineers dated June 2005. In order to demonstrate that the mitigation is successful, hydrology and vegetation monitoring must be conducted for three years to confirm that the Mitigation Site meets the Hydrology Success Criteria and the Vegetation Success Criteria as established by the project specifications and in compliance with federal guidelines for wetland mitigation. 2010 is the second year of monitoring following the re-grading and replanting of the site in 2008. This Report details the 2010 results of the hydrology and vegetation monitoring at the Mitigation Site. 4 HYDROLOGY Hydrology Success Criteria: Project specifications require saturation (within 12 inches of the surface) or inundation of the Mitigation Site for a consecutive period of at least 12.5% of the growing season for one year under average climatic conditions for the Mitigation Site to be deemed to meet the Hydrology Success Criteria. According to the data for WETS Station Morehead City 2WNW, NC5830 having a latitude of 34° 44'N and a longitude of -76° 44'W, published by the National Water and Climate Center of the Natural Resources Conservation Service of the United States Department of Agriculture, the growing season in Carteret County, based on a 50% probability that air temperatures will reach 28° Fahrenheit or higher, runs from March 14 to November 30. That means that the growing season contains 261 days, and 12.5% of 261 days equates to 33 days. Accordingly, for the Mitigation Site to meet the Hydrology Success Criteria, it needs to show saturation (within 12 inches of the surface) or inundation for at least 33 consecutive days between March 14 and November 30 under average climatic conditions. Lot 121 in Dolphin Ridge is located at latitude 34° 39'24"N and longitude -77° 04'29"W. The Mitigation Site is located approximately 20 miles from WETS Station Morehead City 2WNW, NC5830 and approximately 4 miles from State Climate Office of North Carolina Station KNJM - Bogue Field MCALF, in Bogue, North Carolina, having a latitude of 34.69°N and a longitude of -77.02°W. The Mitigation Site has two (2) monitoring wells installed in it. The monitoring wells were installed pursuant to the instructions and procedures detailed in the "Technical Standard for Water-Exhibit Monitoring of Potential Wetland Sites" prepared by the U.S. Army Corps of Engineers dated June 2005. The Monitoring Well Installation Data Sheets for each of the monitoring wells and a survey showing the location of the monitoring wells at the Mitigation Site were included in the Annual Mitigation Report for 2009. The monitoring wells at the Mitigation Site were labeled "A" and "B" for ease of reference. Each monitoring well was manually monitored on a daily basis from March 14, 2010, to November 31, 2010. Monitoring well reports in graph form showing the daily measurements at each of the monitoring wells for each month of the Growing Season are contained in Exhibits 2 - 3 of this Report. All measurements are in inches. Each monitoring well has a separate graph for each month of the Growing Season. Each graph shows the "Date," "Depth of Water From Surface in Monitoring Well," and "Depth of Standing Water Above Surface." Negative numbers indicate that the water level is located below the ground level surface that distance; and positive numbers indicate that the water level is located above the ground level surface that distance. If there is no standing water on the surface, the graph shows the depth of standing water as "0". If the depth of the surface water surrounding a monitoring well exceeded the height of the monitoring well riser, then the measurement shown for the "Depth of Water From Surface in Monitoring Well" is the depth of the surrounding surface water. Monitoring Well Results for Entire Growing Season: A review of the Monitoring Well reports based on the entire Growing Season (without consideration of the amount of rainfall during the Growing Season) indicates that the Mitigation Site experienced saturation (within 12 inches of the surface) or inundation for at least 33 consecutive days of the 2010 Growing Season. The Monitoring Well reports for the entire Growing Season show that: 1. Monitoring Well A had 98 days (vs. 68 days in 2009) where the soil was saturated at a depth of less than 12 inches from the surface and 144 days (vs. 189 days in 2009) where the soil was inundated with water. 2. Monitoring Well B had 95 days (vs. 67 days in 2009) where the soil was saturated at a depth of less than 12 inches from the surface and 145 days (vs. 190 days in 2009) where the soil was inundated with water. 6 Monitoring Well Results for Periods During Growing Season with Average Climatic Conditions: Since one of the parameters of the Hydrology Success Criteria is that the conditions be met "under average climatic conditions," the average climatic conditions during a normal Growing Season must be determined. Once the average climatic conditions are determined, it must be determined if (and when) such average climatic conditions occurred during the 2010 Growing Season. The Monitoring Well data then must be examined to determine if the Mitigation Site experienced saturation (within 12 inches of the surface) or inundation for at least 33 consecutive days during the 2010 Growing Season when the average climatic conditions occurred. To assist in answering these issues, we prepared the charts contained in Exhibit 4 of this Report. The charts in Exhibit 4 of this Report show the following data: 1. The column labeled "Date" shows the date of the measurements. 2. The column labeled "Rain Measured at Site" shows the rainfall data as manually measured on a daily basis at the Mitigation Site at the same time that the monitoring wells were being checked. The column labeled "Rain Per NC CRONOS" shows the Daily Precipitation by Day data published by the State Climate Office of North Carolina for Station KNJM - Bogue Field MCALF, in Bogue, North Carolina. 4. The column labeled "Normal Rainfall" is the Normal Precipitation by Day based on 1971 to 2000 climate records as published by the State Climate Office of North Carolina for the period of March 14 to November 30 for Station 315830 - Morehead City 2WNW, in Morehead City, North Carolina. 7 We then compiled the daily data contained in the charts in Exhibit 4 into the chart below where: 1. The column labeled "Month" shows the month during the Growing Season. 2. The column labeled "Actual Rainfall Measured at Mitigation Site" shows the total rainfall measured for the month at the Mitigation Site. The column labeled "Historic Normal Rainfall" shows the monthly total of the rainfall during the month based on the "Normal Rainfall" reported by the State Climate Office of North Carolina. 4. The column labeled "Actual Rainfall Measured by the Weather Service" shows the monthly total of the Daily Precipitation by Day data published by the State Climate Office of North Carolina for Station KNJM - Bogue Field MCALF, in Bogue, North Carolina. 5. The column labeled "Difference" shows the "Actual Rainfall Measured at a Mitigation Site" less the corresponding "Historic Normal Rainfall." Month Actual Rainfall Measured at Mitigation Site Historic Normal Rainfall Actual Rainfall Measured by the Weather Service Difference March 14 - 31 3.80 2.35 2.56 +1.45 April .70 2.94 .56 -2.24 May .90 4.66 .98 -3.76 June 1.30 4.04 .99 -2.74 July 3.60 5.94 3.94 -2.34 August 9.30 7.55 8.83 +1.75 September 11.60 6.47 10.28 +5.13 October 7.10 4.36 4.56 +2.74 November 1.40 4.07 1.50 -2.67 Totals 39.70 42.38 34.20 -2.68 The above chart shows that Emerald Isle sustained above average rainfalls in March, August, September, and October, and below average rainfalls in April, May, June, July, and November. However, the overall difference for the entire growing season only was a negative 2.68 inches of rainfall, and that represents only approximately a six (6) percent difference for the entire growing season. Consequently, we considered the growing season as a whole to meet the "average climatic conditions" requirement. Although excess rain in a growing season could indicate that an area is a wetlands when in fact it is not a wetlands during a normal rain season, having an area meet the hydrologic requirements for a wetlands when the rainfall is less than the normal amount (as in this case) does indicate that the area would meet the hydrologic requirements during a normal rain season. An analysis of the monitoring well data for the 2010 growing season for the Mitigation Site shows that the Mitigation Site experienced saturation (within 12 inches of the surface) or inundation for at least 33 consecutive days. Consequently, the Mitigation Site met all of the parameters of the Hydrology Success Criteria. The monitoring wells reports for the 2010 growing season show the following: Monitoring Well A met the criteria 242 days of the growing season. This included one period beginning in March of 104 consecutive days where the soil was saturated at a depth of less than 12 inches from the surface or the soil was inundated with water and second period beginning in July of 136 consecutive days where the soil was saturated at a depth of less than 12 inches from the surface or the soil was inundated with water. 2. Monitoring Well B met the criteria 240 days of the growing season. This included one period beginning in March of 104 consecutive days where the soil was saturated at a depth of less than 12 inches from the surface or the soil was inundated with water and second period beginning in August of 109 consecutive days where the soil was saturated at a depth of less than 12 inches from the surface or the soil was inundated with water. Based on the monitoring well data, the Mitigation Site met the Hydrology Success Criteria for the 2010 Growing Season and would be considered wetlands under the Hydrology Success Criteria. 9 VEGETATION Vegetation Success Criteria: Project specifications require that we establish wetlands vegetation in the Mitigation Site similar to the vegetation in adjacent natural wetlands areas for the Mitigation Site to be deemed to meet the Vegetation Success Criteria. The Mitigation Site was planted with Lizard's Tail (Saururus cernuus), Rush (Juncaceae), Red Maple (Acer rubrum), Button Bush (Cephalanthus occidentalis), Wax Myrtle (Myrica cerifera), Fetterbush (Lyonia lucida), Bald Cypress (Taxodium distichum), and Sweetbay Magnolia (Magnolia virginiana) in 2008. We specifically did not plant any Common Cattail (Typha Latifolia) in the Mitigation Site. With the Mitigation Site being small in size (approximately 4,164.59 square feet), the vegetation may be monitored with a simple visual inspection of the Mitigation Site. The Mitigation Site was visually inspected in July of 2010 and January of 2011. In July of 2010, the Mitigation Site contained healthy wetlands vegetation that was thriving and the Mitigation Site was doing very well. Photographs 1 and 2 in Exhibit 5 show the dynamic growth of the wetlands plants in the Mitigation Site and how similar the Mitigation Site looks to the natural wetlands located north of the Mitigation Site. Without the metal posts delineating the Mitigation Site, it would be difficult to say where the Mitigation Site stopped and the natural wetlands begin. The original plantings of Common Rush, Fetterbush, Wax Myrtle, and Bald Cypress in the Mitigation Site showed a high survival rate and other wetlands plants are naturally propagating into the site, including Common Cattail (Typha Latifolia). Photograph 3 in Exhibit 5 shows a Bald Cypress in the Mitigation Site. Photograph 4 in Exhibit 5 shows a Wax Myrtle in the Mitigation Site. Photograph 5 in Exhibit 5 shows a Fetterbush in the Mitigation Site. Photographs 6 and 7 in Exhibit 5 were taken on January 16, 2011. The Mitigation Site is doing well and looks like the natural wetlands it adjoins. As the wetlands plants continue to grow and natural propagation occurs from the adjoining wetlands, the Mitigation Site will become integrated into the adjoining natural wetlands. Although the Red Maple and the Sweetbay Magnolia died, the extensive growth of the other wetlands plants shows how well the Mitigation Site has been transformed into wetlands. 10 The Wetlands Indicator Status for some of the plants shown in the photographs is as follows: Plant Name Type Wetland Indicator Status Rush Rush FACW-OBL (Juncaceae) Wax Myrtle Shrub FAC+ (Myrica cerifera) Bald Cypress Tree OBL (Taxodium distichum) Common Cattail Herb OBL (Typha Latifolia) Fetterbush Shrub FAC W Lyonia lucida The Vegetation Success Criteria has been met by the survival and growth of many of the wetlands plants that were planted in the Mitigation Site in 2008 and by the natural propagation of other wetlands plants that is occurring. All indications are that the good survival and growth rate and the natural propagation will continue. CONCLUSION The Mitigation Site is doing well. The Mitigation Site met the Hydrology Success Criteria and the Vegetation Success Criteria in 2010. The Mitigation Site is functioning like the natural wetlands that it borders.
