What Croton-on-Hudson said about its streams

The Village of Croton-on-Hudson told the county in 2021 that its maps adequately address flood risk "except for the Hudson River since FEMA is in the process of issuing a revised flood hazard map for the Hudson River which will include higher flood elevations and V zones", and that the Hudson River shoreline, the Croton River valley and "various smaller stream channels that are not mapped as SFHA" are prone to flooding.

The ANSI/IICRC S500 water damage standard, as quoted by its consensus body, defines Category 3 water as "grossly contaminated" water that "can contain pathogenic, toxigenic or other harmful agents", with examples that include "sewage; waste line backflows that originate from beyond any trap regardless of visible content or color; all forms of flooding from seawater; rising water from rivers or streams".

What a Croton-on-Hudson assessment decides
The report decides whether you have a removal job or a drying job, and in Croton that turns on which water got in. A brook that rose over its banks and into the house counts as rising stream water, the trade's most contaminated class, so what it soaked is removed. Rain running down a slope toward the foundation is judged on inspection and can often be dried. The Village has told the county that besides the Hudson and the Croton River valley, various smaller stream channels not mapped as flood hazard areas are prone to flooding, so a map check alone will not tell you which you had.

Croton owners: deciding on an inspection
Book an assessment when outside water reached finished space or when you cannot say whether it rose from a brook or ran off the hill. Four in five Croton homes are owner occupied, so the report is also your record, useful when you sell and a buyer asks what happened. Skip it for a small patch from a clean source; clean it yourself. And if nobody can see mold but the basement took stream water, book it anyway, because what matters is what the water soaked, not what you can see yet.
A brook near the lot?
Tell the assessor about any stream or ditch near the house, mapped or not. The Village says small unmapped channels flood.
The slope above the house
Runoff from uphill is a different water from a brook, and usually a smaller job. Say what is uphill.
Keep the report
An owner's written record of a water event and its fix is worth filing with the house papers.
Did a stream come up, or did the hill drain toward you?
Tell us what happened and when. We will line up a licensed assessor for the Croton address, with no obligation.

Croton-on-Hudson questions about stream water and inspection
Our house is not in a flood zone. Could it still have been stream water?
Yes. The Village told the county that smaller stream channels not mapped as flood hazard areas are prone to flooding. The assessor judges where the water came from, not the zone.
Are new Hudson flood maps coming?
In 2021 the Village said FEMA was revising its Hudson River maps with higher flood elevations and new V zones. Check the current map for your address before you rebuild a lower level near the river.
