T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation6.17 Light Emissions and Visual EnvironmentBased on the impact analysis presented in Chapter 5, Environmental Consequences, Alternative B4 would notresult in significant impacts related to light emissions or the visual environment. While no mitigation isrequired, BMPs would be followed to reduce impacts from light emissions of the Preferred Alternative.Additional light poles associated with the expansion and modification of the Airport roadway system woulduse downcast hoods that avoid light propagation to neighboring areas. Access to the new structured parkinggarage would face Airport land and a solid wall or screening would be designed facing the adjacentneighborhood to minimize light propagation to neighboring areas.6.18 Energy Supply, Natural Resources, and Sustainable DesignBased on the impact analysis presented in Chapter 5, Environmental Consequences, Alternative B4 would notresult in significant impacts concerning energy, natural resources, or sustainable design and, therefore, nomitigation is required. Acknowledging the intent of the FAA to encourage construction that exemplifies thehighest standards of design including principles of sustainability, and the intent of the State of Rhode Island torequire State buildings to be constructed to a LEED Silver rating, RIAC has committed to managing the design,construction, operation, and maintenance of the Airport using sustainability principles to the extent practicable.6.19 Construction Period MitigationTemporary, short-term impacts from construction activities would not be significant and would be mitigated tothe maximum extent practicable. All construction activities would comply with the most recent edition of FAA’sAdvisory Circular 150/5370-10, Standards for Specifying Construction of Airports. 492 During construction, a portionof the water main in Airport Road that will be under the Runway 16 RSA would be relocated as a constructionmitigation measure. Additionally, appropriate construction mitigation measure requirements would beincorporated into the contract documents and specifications governing the activities of contractors andsubcontractors constructing elements of the Preferred Alternative. On-site resident engineers and inspectorswould monitor construction activities to ensure that mitigation measures are properly implemented. Table 6-16presents the proposed construction mitigation measures. Construction period mitigation is only included forthose environmental categories for which there would be short-term construction-related impacts.492 FAA Circular 150/5370-10, Standards for Specifying Construction of Airports, U.S. Department of Transportation, FAA, September 30, 2009.Chapter 6 – Mitigation 6-39 July 2011\\Mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH06_Mitigation_JUL_2011.doc
