T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationBay (Figure 4-32), and is subject to the Greenwich Bay SAMP goals and objectives. 437 RICRMC also hasauthority over freshwater wetlands in the vicinity of the coast. However, the Airport itself is not withinRICRMC freshwater wetland jurisdiction.5.15.2.1 Finding: No Significant Coastal Resources ImpactsIn order for FAA to make a determination of CZM Consistency, the Preferred Alternative must be designed tocomply with applicable performance standards of the CRMP, Rhode Island Soil Erosion and Sediment ControlHandbook, Rhode Island Stormwater Design and Installation Standards Manual, and the SAMP goals and objectives.Following its review of the FEIS, RICRMC must provide its concurrence regarding CZM Consistency.Alternatives B2 and B4 would be designed to comply with applicable performance standards of the CRMP,Rhode Island Soil Erosion and Sediment Control Handbook, and Rhode Island Stormwater Design and InstallationStandards Manual, and the SAMP goals and objectives. The FAA finds that Alternatives B2 and B4 will not resultin a significant impact to coastal resources.5.15.3 MethodologyThe analysis methodology consists of comparing proposed T.F. Green Airport Improvement Program activitieswith performance criteria identified in applicable RICRMC guidance. The CZM consistency evaluation includesidentification of any coastal resources that could be affected directly by the Improvement Program, assessmentof construction management to prevent erosion, assessment of stormwater treatment and changes tostormwater flows, mitigation for wetland impacts, and an assessment of overall impacts on Greenwich Bay.Consideration is given to stormwater runoff characteristics and potential downstream water quality and habitatimpacts that would lead to the Alternatives being subject to the CZM Consistency requirement. RIDEM willreview all stormwater and wetland issues in accordance with its guidance and regulations. Detailed technicalinformation to support consistency with these standards is presented in Section 5.10, Wetlands and Waterways,Section 5.11, Water Quality, Section 5.12, Fish, Wildlife, and Plants, and Section 5.14, Floodplains.5.15.4 Impact AssessmentThe following section considers potential impacts to coastal resources as a result of the No-Action Alternativeand Alternatives B2 and B4.5.15.4.1 No-Action AlternativeThe No-Action Alternative would have no direct impacts to coastal resources since there are no coastalresources within the Project Area.5.15.4.2 Alternative B2Like the No-Action Alternative, Alternatives B2 and B4 would have no direct impacts to any coastal resourcesbecause the Project Area does not contain any coastal resources. The Fully Relocated Airport Road included inAlternative B2 may impact freshwater wetlands subject to the jurisdiction of the RICRMC under the Rules andRegulations Governing the Protection and Management of Freshwater Wetlands in the Vicinity of the Coast. 438 Warwick437 Greenwich Bay SAMP, Rhode Island Coastal Resources Management Council, www.crmc.state.ri.us/regulations/SAMP_GreenwichBay.pdf.438 State of Rhode Island Coastal Resources Management Council.
