T.F. Green Airport Improvement Program - FEIS Chapters - PVD

T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationRoadway widening along Warwick Avenue under Alternative B2, and the increased traffic demand expectedcould impact the designation of the roadway segment as a “Suitable Road” for bicycle travel by RIDOT.Squantum Drive is also classified as a “Most Suitable Road” by RIDOT. This designation could be altered due tothe proposed alignment of Squantum Drive with Fully Relocated Airport Road under Alternative B2.Appropriate pedestrian and bicycle accommodations would be included in the final design of Fully RelocatedAirport Road.6.21.5 Air QualityIn accordance with the NAAQS, 494 the air quality impact assessment findings show that, like Alternative B4,Alternative B2 is not expected to have a significant effect on air quality conditions locally, regionally, orstatewide (see Section 5.7, Air Quality, of Chapter 5, Environmental Consequences). Therefore, no specific airquality mitigation measures are required under NEPA or the General Conformity Rule. Other impacts related toair quality associated with the construction activities would be mitigated as described for Alternative B4 inSection 6.19, Construction Period Mitigation.6.21.6 Historic, Architectural, Archaeological, and Cultural ResourcesAs both Alternative B2 and B4 result in a finding of adverse effect to historical properties as defined underSection 106 of the NHPA and will impact historical cemetery (WHC 26) protected under Rhode Island GeneralLaw 23-18-22 et seq. and Chapter 12 of the Code of Ordinances of the City of Warwick, the proposed mitigationmeasures presented in Section 6.7, Historic, Architectural, Archaeological, and Cultural Resources, are the same forboth alternatives. Under Alternative B2 additional archaeological investigations and mitigation in the form of adata recovery program would be required to address an adverse effect to the Double L Site, an archaeologicalresource that is potentially eligible to the NRHP. Additional archaeological investigations would be required forthe AMF Road modification; if significant archaeological resources are identified, mitigation in the form of datarecovery would be required.6.21.7 Section 4(f) ResourcesMitigation is proposed for Section 4(f) resources that will be physically or constructively used under AlternativeB2: the eligible airport historic district; Hangar No. 1; Hangar No. 2, the Rhode Island State Airport Terminal;and Winslow Park. 495 Both Alternatives B2 and B4 would result in adverse effects to historical properties underNHPA Section 106 and a use under Section 4(f) of the USDOT Act. Both Alternatives B2 and B4 result in aphysical use of Winslow Park, a Section 4(f) recreational resource. Mitigation for Section 4(f) impacts tohistorical resources and recreational resources is the same under Alternative B2 and B4. Mitigation for historicalresources protected under Section 4(f) is described in Section 6.7, Historic, Architectural, Archaeological, andCultural Resources, and Chapter 7, Final Section 4(f)/Section 6(f) Evaluation. Mitigation for impacts to WinslowPark include relocation of the impacted facilities to the Cedar Swamp Road location as detailed in Chapter 7,Final Section 4(f)/Section 6(f) Evaluation.494 CFR Title 40, Part 50.495 Alternative B2 would result in a constructive use of Hangar No. 2 because of visual and access impacts but there would be no use under Alternative B4.Chapter 6 – Mitigation 6-47 July 2011\\Mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH06_Mitigation_JUL_2011.doc
