Data is based on the 2000 Census. Although some 2010 census data was released in March 2011, a sufficientlevel of census data for the FEIS analysis was not released prior to the filing of the FEIS.1 Excludes 658 people who have been relocated under the Completed Part 150 VLAP and 317 people which would be relocated under the Current Part 150 VLAPrespectively for a total of 975 people relocated due to both programs (to be completed by 2015).No elderly subsidized housing development within the City of Warwick would be affected by noise levelsgreater than DNL 65 dB. The Charles Ford Terrace development, which is northeast of the Airport nearWarwick Avenue, would be exposed to noise levels close to DNL 65 dB (63.2 dB in 2015 to 64.2 dB by 2025) forthe No-Action Alternative in three modeled years (2015, 2020, and 2025). This facility is affected by flights fromRunway 5-23.The Environmental Desk Reference for Airport Actions indicates that the EIS must identify any non-residential noisesensitivesites within the DNL 60 dB noise contour in order to disclose any potential sites with a 3.0 dB changein noise levels between DNL 60 and 65 dB. 288 Figure 5-9 shows the location of non-residential noise-sensitivelocations within the 2025 DNL 60 dB contour of all of the Alternatives. Table 5-10 presents a comparison ofpredicted noise levels at non-residential noise-sensitive locations for the No-Action Alternative and AlternativesB2 and B4 in 2015, 2020, and 2025. No non-residential noise-sensitive locations would have a change of 3 dB innoise levels between DNL 60 and 65 dB for either Alternative B2 or B4.288 Environmental Desk Reference for Airport Actions, FAA, October 5, 2007, Chapter 17, section 8.b(2).Chapter 5 - Environmental Consequences 5-18 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
