Mold Removal in Oceanside, NY, Where the Map Says Zone X
FEMA's flood map puts the middle of Oceanside in Zone X, outside the special flood hazard area, so the coastal construction rules do not govern a house there. Being outside the mapped zone is not the same as being outside the water, though: the Town of Hempstead has been paid on 2,040 flood claims for properties outside it, so a damp space under an Oceanside floor is worth investigating rather than dismissing.

Lido Beach, Point Lookout, Oceanside, Baldwin, Merrick, Bellmore and Wantagh are unincorporated communities with no village government and no annex of their own in the county hazard plan. Floodplain administration for them sits with the Town of Hempstead, whose Flood Damage Prevention Ordinance is at Town Code Section 144-3.G and was last amended January 19, 2020. The Town reports a designated floodplain manager, and that the elevation of homes, businesses, roads and bulkheads has been its primary mitigation tool in flood prone areas. The Town's own position is that all of the back bay communities in the Town located on the south shore of Nassau County are prone to flooding.

In the same FEMA report the Village of Atlantic Beach, the Village of Valley Stream, the Village of Rockville Centre and the Town of Hempstead, which covers Lido Beach, Point Lookout, Oceanside, Baldwin, Merrick, Bellmore and Wantagh, hold no Community Rating System class at all, so no CRS premium discount applies at those addresses. Every one of them is listed as participating in the National Flood Program with a current effective map date of September 11, 2009.

Oceanside has no village hall of its own, and that changes who you call
Oceanside is an unincorporated part of the Town of Hempstead. There is no village government, no hazard plan annex of its own and no separate flood insurance line for it, so permits and flood requirements go to the Town under Town Code Section 144-3.G, and a contractor who names an Oceanside building department has not worked here. The Town's own stated position is that all of the back bay communities in the Town on the south shore of Nassau County are prone to flooding, and the Town holds no Community Rating System class, so an Oceanside flood policy carries no community discount behind it. The housing record points the survey: 87.8 percent of units were built in 1979 or earlier and only 6.8 percent are renter occupied, so the usual causes are original bathroom venting, a finished lower level and grading, and the owner is almost always the person who can authorize the work.
