Sixty-seven residential units (51 single-family and 16 multi-family) would be acquired forconstruction (mandatory) of the extension of Runway 5-23 and Fully Relocated Airport Road. Thirty-six residentialunits (32 single-family and four multi-family units) could be acquired under a Future Build VLAP between 2020and 2025 for noise mitigation. For FAA-recommended RPZ clearing, 134 residential units (50 single-family and84 multi-family) would be eligible for acquisition. No subsidized low- and moderate-income housing units wouldbe acquired under Alternative B2 (refer to Section 5.5.6, Affordable Housing Analysis).Indirect Impacts to Housing AffordabilityUnder Alternative B2, the total reduction in housing units (both affordable and non-affordable units) would be237 units. These housing units equate to 0.33 percent of the estimated 2006 housing stock in Kent County(72,914 units) and 0.63 percent of the estimated housing stock in Warwick (37,401 units). 344 If no replacementhousing were constructed and if all relocated households settled within Kent County, overall vacancy rateswould decrease by 0.31 percentage points in Kent County to 4.64 percent from the 2006 Kent County level of4.95 percent. 345 This reduction in vacancy rates could potentially have an indirect impact on housingaffordability by raising rents and home prices within the County.Significant Impacts: There would be no significant social and socioeconomic impacts under Alternative B2 because:• There would be sufficient replacement housing within Warwick and its surrounding communities.• There would be sufficient commercial space for relocating businesses within Warwick and its surroundingcommunities.• There would be no substantial reduction in the Level of Service of roads serving the airport and itssurrounding communities. Alternative B2 would improve traffic circulation surrounding the Airport,specifically with the proposed Fully Relocated Airport Road and the Airport gateway improvements onPost Road (refer to Section 5.6, Surface Transportation).• There would be an insubstantial loss in community tax base. For Alternative B2, the total potential propertytax loss (for mandatory and voluntary land acquisitions) is under one percent (0.75 percent) of the total taxbase for the City of Warwick.344 Source for estimated housing stock: U.S. Census Bureau, 2006, American Community Survey data.345 The loss of units and corresponding impact on vacancy rates is greater if one also takes into account the 135 units lost under the 2009 Part 150 VLAP fornoise mitigation.Chapter 5 - Environmental Consequences 5-94 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
