Six short questions about the water and the house, then your details. Under a minute.

Question 1What brought you here?
Question 2Where does the house sit?

In Westchester this is the question that most often decides what kind of job it is. A house on the Hudson or the Sound can take tidal or surge water, a house in a stream valley takes river water, and a house on higher ground mostly takes groundwater or runoff. The county's own hazard plan puts only about one building in forty inside the mapped flood area, so most wet basements here are outside it.

Question 3Where did the water come from?

Clean water from a supply pipe, rainwater through a wall, and water that rose out of a river, the Sound or a drain are graded differently by the water damage trade's own standard, and the grade decides whether soaked materials can be dried or have to be cut out. Guessing wrong in either direction costs money, so an honest not sure is better than a confident guess.

Question 4How long has it been wet?

Federal guidance says material dried within 24 to 48 hours of a leak will in most cases not grow mold. Past that window the question moves from drying to finding out what has already grown, which is why this changes who we send first.

Question 5What was in the space that got wet?

What has to be removed depends on the materials as much as on the water. Carpet, pad, drywall and insulation that soaked up contaminated water usually come out. Concrete, block and framing are usually cleaned and dried where they are.

Question 6Why look into it now?

This decides what order things happen in. A closing date or a health worry moves the assessment to the front of the queue.

The Village of Ossining listed its flood-prone areas for the county plan as Water Street, Westerly Road, Pine Avenue, Havell Street and Revolutionary Road, and said its flood maps adequately address its risk. The Town of Ossining named the Old Albany Post Road area near the Croton River.

Local Context

Telling Hudson water from upland water in Ossining

What an Ossining inspection settles is where the water came from, and that is not obvious in a village that runs from the river's edge up steep streets. Tidal Hudson water along the low waterfront is graded as grossly contaminated; runoff or groundwater in a house up the hill usually is not, and is judged on inspection. The difference is the difference between removing a finished room and drying it. FEMA's records show 23 of the 34 Ossining village claims with a recorded zone, 68 percent, were rated outside the high risk zones, so the hillside gets wet too.

Deciding

Ossining owners: is an inspection the right first call?

It is if the water reached finished space, if you cannot tell whether it was river water or runoff, or if growth has come back after cleaning. It is not if a small patch on a clean surface has an obvious cause; clean it and fix the cause. Near the flood prone areas the Village names, among them Water Street and Havell Street, river water is a live possibility and the plan will reflect it. Up the hill, the assessor should look at foundation walls too, because a third of village homes predate 1940.

  1. Low ground or high ground

    Tell the assessor roughly where the house sits. The Village's own list of flood prone areas is mostly near the water.

  2. Old foundation walls

    In a prewar house the assessor should check for seepage at the base of the walls, not just the obvious stain.

  3. Before you order materials

    Get the report before you buy drywall or flooring for the rebuild. The kind of water decides what should go back.

Questions

Ossining questions about inspections near the river

Does the Village think its flood maps are accurate?

The Village of Ossining told the county its maps adequately address its risk. Most of its paid claims were nonetheless rated outside the mapped zones, which points to water arriving from sources the map does not draw.

Does the Town of Ossining use a different office?

No. The Town and the Village share one building department at 101 Route 9A, so one office handles questions on either side of the line.
