No water inside the boundary, and a flooding history anyway
The Census Bureau's 2020 relationship file between ZIP Code Tabulation Areas and places puts the whole of Cedarhurst in ZCTA 11516 and measures the village at 1,747,711 square metres of land and zero square metres of water (ZCTA-to-place relationship file). A buyer could read that as a village with no coastal exposure. The state's 2014 Five Towns recovery plan reads the opposite way, because the water here does not come over a bulkhead inside the village; it comes up the creeks. The plan records that inland homes in low-lying areas along Mill Creek in Inwood, Cedarhurst, and Woodmere were severely damaged by inundation that came from tidal flooding of Mill Creek (Five Towns NYRCR plan, PDF).
Five feet, three hundred homes, and a line on Marlborough Road
According to the same plan, roughly five feet of surge moved through the village from Motts Creek, north to south, and about 300 homes were affected, along with Lawrence High School and the Cedarhurst DPW facility; inundation travelled south beyond Peninsula Boulevard to approximately Marlborough Road. The plan also records that flooding occurs regularly in low-lying areas along Peninsula, on a monthly basis, and - the sentence worth keeping in mind at a walkthrough - that information on the existence and condition of check valves is incomplete. Where a cellar in this village has a floor drain, whether a backwater device is fitted, accessible and operable is a question the village record may not answer.
The 2014 project list, and what it costs to fix drainage here
The plan apportioned $3,000,000 to the Village of Cedarhurst from a community allocation the plan caps at $27,600,000 in Community Development Block Grant-Disaster Recovery money, and set out the work it would buy: a first phase at $2,000,000 for installation of check valves, wet weather pumps and a water storage tank; removable flood walls at $500,000 to protect the two buildings on the Cedarhurst DPW site; a second phase at $7,800,000 along Peninsula Boulevard from Rockaway Turnpike to Bayview Avenue; and berm repair at $710,000. These were 2014 proposals. Whether any of them exists on the ground has not been verified, and a buyer relying on drainage improvements should ask the village which were built.
Reading the flood map without over-reading it
Panel set 36059C is the effective Flood Insurance Rate Map here. A polygon query of the National Flood Hazard Layer against the village boundary returns Zone AE alongside two different kinds of Zone X: the 0.2-percent annual chance band, and the area mapped as minimal hazard. Its 0.2-percent polygons are the 500-year floodplain, so out of the flood zone, copied off a listing sheet, says less than it appears to. Lenders, premiums and elevation certificates all follow the designation at the address, which is published at the FEMA Map Service Center.
Who the sewer authority is, and why two county pages both apply
Cedarhurst appears on the county health department's summary of sewer districts by community with Nassau County Department of Public Works as its local sewer authority, carries none of the asterisk that marks a collection-district-only community, and is absent from that document's not-publicly-sewered list. The county's Wastewater Management Program page separately names the Village of Cedarhurst among ten independent treatment facilities that operate within the county. Those statements sit side by side: one names who collects, the other names an operator of treatment works. The district summary bears no date on its face and its server returns no last-modified header, so nothing in the file fixes its vintage; and neither page says whether the house under contract is physically connected. That is an address question, and the county publishes the per-address sewer lookup to answer it before the contract is signed.
A pre-war core with a real two-family layer
Of 2,803 housing units counted in the 2020-2024 American Community Survey, 992 date from 1939 or earlier, the single biggest decade bucket, and the median year built is 1953. Structure type matters here: 1,340 units are detached and 200 attached, but 484 sit in two-unit buildings and 264 in buildings of three or four. Of 2,681 occupied units, 1,788 are owner-occupied and 893 rented; the median value is $861,900 and the population is 7,320. In a legal two-family the scope widens: the rating of the assembly under the cellar ceiling and of the wall between the units, a way out of each sleeping room that does not run through the neighbor, and whether the certificate on file permits the arrangement. Cedarhurst carries the class INCORPORATED PLACE, GEOID 3613233, in the Bureau's 2020 register of places by county, which is why that certificate and the permits behind it are village business rather than town business.
Oil, sewage and what a rescue crew found
Fuel oil or kerosene heats 604 of the village's occupied units, against 1,895 on utility gas. State records return 245 spill incidents under the locality string Cedarhurst, 217 of them petroleum (NYSDEC spill incidents), with the standing caveat that the locality field is postal rather than municipal. The recovery plan puts the two hazards in one sentence: during many water rescues, equipment was contaminated by raw sewage and fuel oil. In a village whose largest age bucket predates 1940, tank history belongs on the contract list rather than the wish list.
Water supply, the station and who turns out
The state health department's Nassau public water system contacts carries no community system bearing the Cedarhurst name, so the purveyor has to come from the seller. Nassau reports 46 public water systems and roughly 500 private wells across the county as a whole. Cedarhurst station sits inside the village on the Far Rockaway branch, fare zone 4, accessibility field FULL in the state rail-station dataset - an attribute, not a site visit. The Lawrence-Cedarhurst Fire Department is described in the plan as an 80 member volunteer organization, and police services in Cedarhurst are provided by Nassau County.
