U.S. Census Data, 2000. Database of previously sound insulated housi ng units provi ded by RIAC.Note: Represents the number of housi ng units and non-residential noise-sensitive sites affected by significant noise levels during a specific year and are not cumulati ve.NA Not Appli cable1 Significant i mpacts are noise impacts that occur if analysis shows that the proposed action would cause noise-sensiti ve areas to experience an increase in noise of at l east DNL 1.5 dB or more at or above DNL 65 dB noise exposure when compared to the No-Action Alternative for the same ti meframe. These resi denceswould be eli gible for sound insulation mitigati on. May include homes already sound i nsulated as part of a previous sound insulati on effort under the Part 150 NCP.This i s because past NCPs accounted for Stage 1 and Stage 2 aircraft in the fleet mi x both of which have si nce been phased out due to noise and fuel use (referto Secti on 4.2, Noi se, of Chapter 4, Affected Envi ronment, for further information).2 Excl udes people that would be relocated and housing units that would be acquired for construction (mandatory), noise mitigati on under a Future Buil d VLAP andRPZ area cleari ng.3 Jehovah’s Witnesses of Warwick (Site PW017) would experience significant noise impacts i n 2015, 2020, and 2025 and would be eligible for sound insulationmitigation. Baha’i Faith (Si te PW039) would experience signifi cant noise impacts i n 2015, 2020, and 2025, but i t has already been sound insulated and it wouldnot be eli gible for additi onal sound insulation mitigati on. The John Wickes School (SCH524) would experience significant noise impacts i n 2025. It has alreadybeen sound i nsulated, but concurrent with the construction of the runway extensi on, RIAC will conduct additi onal acoustical testi ng of non-residential noisesensitiveproperti es that would be exposed to a noise level increase of at least DNL 1.5 dB at or above DNL 65 dB. Results of the testing may allow for installationof air conditi oning, or other noise related mitigati on.4 Of the Project-related significant noise impacted housi ng units, these units have already been sound i nsulated under a previous sound insulation program.Database of properties provi ded by RIAC. Previously insulated properti es will be confirmed prior to initiating a future sound insulati on program.5 Baha’ i Fai th and John Wi ckes School have been sound insulated as part of a previous sound insulati on effort under the Part 150 NCP.6 As noted, the numbers presented are not cumulative. Through 2025, a total of 24 housing units would be newly eligible for Project-related noise mitigation (soundinsulation) due to signifi cant noise impacts (23 units in 2015, one additi onal unit i n 2020, and no additional units i n 2025).23 623 621 66.2.3.1 Residential Sound Insulation for Noise MitigationAll residential units and other non-residential noise-sensitive land uses that would be exposed to a significantincrease in noise (at least 1.5 dB increase or more in the DNL 65 dB or above noise contour intervals) would beeligible for sound insulation. After taking previous sound insulation efforts of the Completed Part 150 VLAPprogram into account, in both 2015 and 2020, a total of 23 previously non-sound-insulated residences would beeligible for sound insulation mitigation. Assuming that FAA funding is made available, RIAC would begin thesound insulation program following the last phase of project-related land acquisition mitigation (under the Part150 NCP discussed below). In 2025, a total of 21 residences would be eligible for sound insulation underChapter 6 – Mitigation 6-9 July 2011\\Mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH06_Mitigation_JUL_2011.doc
