Which Greenburgh you are in, and which office holds the floodplain
First, which Greenburgh. The town contains six incorporated villages, Ardsley, Dobbs Ferry, Elmsford, Hastings-on-Hudson, Irvington and Tarrytown, each with its own annex in the county plan and its own floodplain administrator, so this page is about the unincorporated town, roughly 18 of its 31 square miles. There, floodplain management sits with the Bureau of Engineering rather than the building counter, nobody on staff holds the floodplain manager credential, and the NFIP service provided is permit review, so a below grade rebuild should be raised with Engineering before plans are drawn. The loss record for the unincorporated town alone is 420 paid claims and $4,998,461.57 against 224 policies in force, with 46 repetitive loss properties, so most of the damage is landing on owners with no policy behind it, and 18 of the 102 claim records in the 10530 Hartsdale ZIP code carry a date of loss on or after 1 August 2021, which means anyone comparing their property to how it behaved in the 2000s is working from stale evidence. The town is candid about the drainage. It names basement and ground floor flooding on East Hartsdale Avenue from a tributary as an unresolved problem it has engaged consultants on, and lists degraded or undersized systems at West Hartsdale Road, Stadium Road, Jackson, Old Jackson and Sprain Avenue, along Kraft-Sheldon Brook, at Manhattan Brook by the county complex, and on Route 9A at Beaver Hill. None of those will be rebuilt quickly, so protection for a property in those areas has to be on the property itself. As for the houses, the largest single cohort in the town is the 1950s at 9,031 homes and 17,810 are single family detached, which is the era of shallow poured foundations and later finished basements with no vapor barrier, the most common source of below grade mold here. No mold assessment contractor is registered anywhere in the 10530 ZIP code, so in a town this size the licensed first step is the binding constraint on how quickly work can start.
