2.0 INTRODUCTION
In the late 1980's Nassau Corporation initiated the construction of the Dolphin Ridge and Royall
' Oaks residential development in Emerald Isle, Carteret County, NC. Construction of residential
homes and driveways on Lot 2 in Royall Oaks and Lots 9, 12, and 93 in Dolphin Ridge
developments will result in the filling of approximately 0.08 acres of jurisdictional waters. These
' wetlands are described in detail in the Wetland Mitigation Plan, Dolphin Ridge and Royall Oaks
Subdivisions, Carteret County, North Carolina (SEI 2005).

' To compensate for the loss of wetlands, the Nassau Corporation created 3 mitigation areas in the
developments on lots 11/12 in Dolphin Ridge, and lots 39, 41 in Royall Oaks. The Dolphin
Ridge mitigation includes 1,666 square feet of Maritime Evergreen Forest Wetland. The Royall
Oaks mitigation includes two mitigation areas. Lot 39 is includes the creation of 1,443 square
feet of interdune pond wetlands. Lot 41 is the creation of 2,160 square feet of interdune pond
' wetlands. The cumulative area of mitigated wetlands is 5,269 square feet, or 0.08 acres (1:1 ratio
for impacts).
Table 1 provides a timeline of significant mitigation activities. Table 2 provides a list of the
species to be installed in the mitigation areas.

3.0 GOALS, OBJECTIVES, AND SUCCESS CRITERIA
As specified in the wetland mitigation plan (SEI 2005) the creation of 5,269 square feet of
wetland to compensate for the loss of wetlands during construction. The mitigation areas are to
provide all key habitat and hydrolic features of the existing wetland on the subject property.
Three vegetative cover percentages were listed as benchmarks in the Mitigation Plan, they are:
1. Facultative zone - 75% plant species with a wetland indicator status of
Facultative or wetter and 25% having Upland status to achieve a total aerial
coverage of 75%.
2. Facultative Wet zone - 25% of plant species having a wetland indicator status of
Obligate and 75% having Facultative or wetter status to achieve a total aerial
coverage of 60%.
3. Obligate zone - <50% of plant species having a wetland indicator status of
Obligate to achieve a total aerial coverage of 25%.
Piezometer tubes are also to be installed in the center of the 1 foot contours of the mitigation
areas to monitor groundwater levels
' 4.0 METHODS
Information in this section is described based on data collected during a site visit to be
determined. Once the planting is complete and piezometer tubes are installed, data will be
collected utilizing the area's vegetation percent coverage, hydrology from piezometer tubes and
soil probes, as well as measurements to confirm wetland size.
Details on data collection will be included in a report addendum at the end of the month, once all
planting is complete.
5.0 RESULTS
1 As shown in the attached photos, all construction work is complete as of May 17, 2006. The
planting process has been initiated, however, due to a shortage of the plants specified in the
' Mitigation Plan, the process is not complete. The remaining planting is scheduled for the first
full week of June. Afterward, data will be collected and submitted as an addendum to the
existing Monitoring Report.
' Surveyors have been notified to complete the "as-built" survey and submit to Spangler
Environmental. Spangler Environmental will include the as-built survey to the addendum to be
submitted at the end of June 2007.
