T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationPosnegansett Lake. To the south, it extends across West Shore Road and close to Post Road (U.S. Route 1) in theGreenwood neighborhood of Warwick. Along Runway 16-34, the DNL 65 dB contour is much closer in to theAirport due to its limited runway use. The contour does not extend off Airport property to the east, but doesextend to the west across Airport Road and to Post Road.There are some areas off-Airport that are exposed to noise levels of DNL 70 dB or above. One small area is to thesouth of the Airport just off the end of Runway 5 and another area is just to the north of Runway 23. There isalso an area along the east side of the Airport, north of Runway 16-34, which is exposed to noise levels ofDNL 70 dB or above under the Baseline Condition.Noise Impacts to Population and HousingThe DNL 60, 65, 70, and 75 dB noise contours are entirely within the City of Warwick. Estimates of the numbersof people and the numbers of housing units within each noise exposure contour are summarized in Table 4-1and the extent of the contours is shown in Figure 4-3.Table 4-12004 Noise-exposed Population and Housing Units in the City of WarwickDNL 75 to DNL 70 to DNL 65 to Total AboveMeasure 80 dB 75 dB 70 dB DNL 65 dBPopulation 0 85 2,982 3,067Housing Units 1 0 36 1,269 1,305Source: HMMH, 2005. U.S. Census Data, 2000. (Although some 2010 census data was released in March 2011, a sufficient level of census data for the FEIS analysiswas not released prior to the filing of the FEIS.)Based on INM Version 6.1 and the 2004 DNL noise contours.1 Population based on 2000 census data of 2.5 persons per household.Population and housing counts for noise exposure were derived from year 2000 Census Data. 159 Therefore, thesecounts may include properties exposed to noise above DNL 65, 70 and 75 dB that have already been acquired asa result of the Completed Part 150 VLAP (discussed below). There are no publicly subsidized housing unitswithin the Baseline Condition DNL 65 dB noise contour.Based on the 2000 NEM update, RIAC updated its Part 150 program which included a phased VLAP for noisemitigation. The number of residential parcels acquired and residences sound insulated as of December 31, 2004are shown in Table 4-2 and displayed in Figure 4-4.159 This EIS uses the most current U.S. Census data available and appropriate for the community analysis. In general, the 2000 U.S. Census data is the mostcomplete as it includes data from all households that completed census forms that year. Since 2000, the U.S. Census Bureau has prepared a series ofsurveys and estimates. These are not as comprehensive as the 2000 survey, but are still appropriate to use for some analyses. Although some 2010census data was released in March 2011, a sufficient level of census data for the FEIS analysis was not released prior to the filing of this FEIS.Chapter 4 – Affected Environment 4-7 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH04_Affected_Env_JUL_2011.doc
