This is an annual report for temporary impacts associated with the bridge replacement of Bridge No. 16 on NC 50-210 over the Intracoastal Waterway. The project was accepted as complete on October 4, 2019. The temporary impacts encompass approximately 0.03 acres for roadway/bridge and 0.10 acres for utility temporary impacts from temporary fill and hand clearing in CAMA wetlands. The area that was impacted is being monitored to ensure that it re -attains jurisdictional wetland status. The areas to the North of the Intracoastal Waterway where the temporary work bridge pilings were removed and the temporary utility impact areas occurred adjacent to NC 50-210 were planted in June 2018. The temporary work bridge pilings to the South of the Intracoastal waterway and the temporary impact area from the NCDOT Geotechnical Unit's boring machine adjacent to the Surf City Park were planted in April 2021. All other temporary impact areas were left to re -vegetate naturally. Hydrologic monitoring is not required for this site; however, vegetation monitoring is required for three years. After the fourth year of monitoring, the Surf City Bridge Temporary Impact Site shows by visual observation that the temporarily impacted areas are re -attaining jurisdictional wetland status. In April 2022, NCDOT and Regulatory Agencies held an onsite meeting to review temporary wetland impact sites. The Regulatory Agencies agreed to discontinue monitoring all sites, except for, Site 4 (temp. work bridge impact area — beach side) at Photo Point #2. Regulatory Agencies requested NCDOT complete a supplemental planting and to continue monitoring this area. Based on the Year 4 monitoring, approximately 50% of the marsh grass plugs planted in May 2022 were noted surviving at this time. NCDOT proposes to continue vegetation monitoring at the Surf City Bridge Temporary Impact Site 4 in 2023. 1 1.0 INTRODUCTION 1.1 Project Description The Surf City Bridge Temporary Impact Site is located in Pender County at Bridge No. 16 on NC 50-210 over the Intracoastal Waterway (Figure 1). The temporary impacts encompass approximately 0.03 acres for roadway/bridge and 0.10 acres for temporary utility impacts from temporary fill and hand clearing in CAMA wetlands. The area that was impacted is being monitored to ensure that it re -attains jurisdictional wetland status. Hydrologic monitoring is not required for this site; however, vegetation monitoring is required for three years. 1.2 Purpose In order for a temporary impact site to be considered successful, a site must meet vegetation success criteria. This report details the vegetation monitoring in 2022 at the Surf City Bridge Temporary Impact Site. Hydrologic monitoring was not required for the site. 1.3 Project History June 2018 September 2019 October 2019 August 2020 April 2021 August 2021 April 2022 May 2022 September 2022 1.4 Debit Ledger Marsh Grass Planting Vegetation Monitoring (Year 1) Project Acceptance Date Vegetation Monitoring (Year 2) Marsh Grass Planting Vegetation Monitoring (Year 3) Onsite Regulatory Agency Meeting Supplemental Marsh Grass Planting @ Site 4 Vegetation Monitoring (Year 4) The restoration of the Surf City Bridge temporary impact site was used entirely to compensate for temporary impacts on the B-4929 project. There were no wetland mitigation credits generated from the restoration of the impacted area. 2 2.0 VEGETATION: SURF CITY BRIDGE TEMPORARY IMPACT SITE (YEAR 4 MONITORING) 2.1 Success Criteria CAMA Condition #25 Due to the possibility that shading, compaction, hand clearing, mechanized clearing, excavation, and/or other site alterations might prevent the temporary Coastal Wetland impacts from re -attaining pre -project wetland functions, the permittee shall provide an annual update on the Coastal Wetland areas temporarily impacted by this project. This annual update shall consist of photographs and a brief written report on the progress of these temporarily impacted areas in re -attaining their pre -project functions. The permittee shall schedule a meeting with DCM to verify the extent and location of the temporary impacts upon project completion. Within three years after project completion, the permittee shall hold another agency field meeting with DCM to determine if the Coastal Wetland areas temporarily impacted by this project have re -attained pre -project wetland functions, DCM will determine whether compensatory mitigation shall be required for these impacts. 2.2 Description of Species The following wetland species were planted in the temporary impact areas to the North of the Intracoastal Waterway: Juncus roemerianus, Black Needle Rush Spartina alterniflora, Smooth Cordgrass 2.3 Results of Vegetation Monitoring The area where the temporary impacts occurred is re -attaining jurisdictional wetland status. Site 4 (temporary work bridge area — beach side) is continuing to revegetate naturally and with the supplemental plantings that have occurred. Approximately 50% of the most recent marsh grass planting that took place in May 2022 was surviving. 3 2.4 Conclusions There were approximately 0.03 acres for roadway/bridge and 0.10 acres for temporary utility impacts from temporary fill and hand clearing in CAMA wetlands. There were no plots established on the site. By visual observation, the Surf City Bridge Temporary Impact Site shows that the planted species are surviving and the impacted areas are re - attaining jurisdictional wetland status. 4.0 OVERALL CONCLUSIONS AND RECOMMENDATIONS NCDOT proposes to continue vegetation monitoring at the Surf City Bridge Temporary Impact Site 4 in 2023. 4 t { �. _ram i' aw�' • - _� .. .
