T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationTable 6-1Summary of Potential Proposed Mitigation for Significant ImpactsMitigation Measure Alternative B2 Alternative B4Noise• Provide sound insulation for residences l ocated at or above DNL 65 dB that would experience a noise increase of at l eastDNL 1.5 dB when compared to the No-Action Alternative for the same ti meframe 1 • Provide sound insulation for non-residential noise-sensiti ve receptors that would experience a noise increase of at least DNL1.5 dB at or above DNL 65 dB when compared to the No-Action Alternative for the same timeframe (Jehovah’s Wi tnesses ofWarwick) Compatible Land UseSee Noise X XHistoric, Architectural, Archaeological, and Cultural Resources• Prepare archival documentation for the National Register eli gible airport historic district (including the Historic District, StateX XTermi nal, and Hangars No. 1 and 2) 2 • Develop a physical and electronic display depicti ng the historical development of the airport.• Prepare list of items from Hangar No. 1 for possible salvage and curation.• For WHC 26, l ay the headstones flat with protecti on, relocate the headstones, or other relocation measures determi ned bythe Warwick Hi storical Cemetery Commission through permitting. • Archaeological Resources, consult with RIHPHC and NITHPO to develop appropriate archaeological surveys to identi fyarchaeological si tes and evaluate their significance and eligibili ty to the NRHP i n areas of potenti al effect unknown at thistime if not previousl y surveyed. If determined eligible for listing in the NRHP, coordinate with RIHPHC and NITHPO to review avoidance and/or mitigation options. Section 4(f) Resources• Replace i mpacted Winslow Park recreation facilities on another site to mitigate for the physical use impact X X• For eli gible airport historic district, State Termi nal, and Hangar Nos. 1 and 2 mitigati on (see Historic, Architectural,Archaeological, and Cultural Resources)XXWetlands and Waterways 3• Replace functions and values of impacted wetl ands (5.8 acres for Alternative B2 and 5.0 acres for Alternative B4) Wetland Mitigation Site 1: 3.0 acres on-site wetland creation Wetland Mitigation Si te 2: culvert replacement at Lakeshore Drive (longer culvert for B2) Wetland Mitigation Site 3: 1.5 acres on-si te wetland restorati on and enhancement (reduced to 0.7 acres under Alternati ve B2) Wetland Mitigation Si te 5: 1.7 acres of wetland restorati on along the Pawtuxet River Wetland Mitigation Si te 6: 0.4 acres on-site wetland creation (expanded to 1.0 acre for Alternative B2) Wetland Mitigation Si te 7: 1.0 acres of wetland creation/restoration in the exit ramp infield to Route 37 Wetland Mitigation Si te 8: 32.0 acres off-site wetland and upland buffer preservation Wetland Mitigation Site 12: 8.0-12.0 acres off-site coastal wetland and upland buffer preservationFloodplains• Provide compensatory flood storage (incorporated in design) X XNotes: Refer to Table 5-131 of Chapter 5, Envi ronmental Consequences, for a summary of significant i mpacts by alternative. In accordance wi th FAA Order 1050.1E,Environmental Impacts: Policies and Procedures, FAA, United States Department of Transportation, March 20, 2006, no mitigation for significant impacts is required forthe other environmental impact categories, including: Social and Economic, and Environmental Justice, Chil dren’s Health and Safety; Surface Transportation; Ai rQuality; Water Quality; Fish, Wildlife, and Plants; Threatened and Endangered Speci es; Coastal Resources; Farmlands; Hazardous Materials and Soli d Waste; LightEmissions and Vi sual Envi ronment; and Natural Resources and Energy Supply.RIHRA Rhode Island Histori c Resource Archive.RICRMC Rhode Isl and Coastal Resources Management Council .1 Accordi ng to FAA Order 1050.1E, significant impacts are those residential units and non-residential noise-sensiti ve land uses that would be exposed to noise levels ofat l east 1.5 dB increase or more withi n the DNL 65 dB contour or above due to the project.23The level of documentati on, either HABS/HAER or RIHRA will be determined through consultati on. Hangar No. 2 would be impacted by Alternati ve B2 only.Not all sites are proposed for mitigati on. This is a list of available mitigation opti ons.
