How Schenectady County floods

Flash flooding from summer thunderstorms and heavy rainfall events dominates Schenectady County's flood profile. According to NOAA Storm Events Database records from the last 30 years, the county experienced 51 general flood events resulting in one death, 41 flash flood events, and 2 tropical storm events. Recent weather narratives illustrate these risks, including slow-moving frontal systems that produced widespread heavy rainfall and flooding from April 7 to 8, 2022, as well as severe thunderstorm activity on July 14, 2023, that resulted in downed trees, power outages, and localized flooding.

National Flood Insurance Program claims data demonstrate that property risks extend across multiple zones. Zone A accounts for 200 claims with an average payout of $35,957 and an average recorded water depth of 22 inches. Properties designated as Zone X recorded 32 claims with an average payout of $44,913 and an average recorded water depth of 24 inches. Meanwhile, unshaded Zone X properties filed 66 claims with an average payout of $8,723 and an average recorded water depth of 8 inches, and shaded Zone X properties recorded 19 claims averaging $15,462 with an average water depth of 6 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within high-risk Special Flood Hazard Areas such as Zone A, while remaining aware that moderate-to-low risk zones like Zone X also experience significant flood claims and standing water depths averaging up to 24 inches.

From the storm reports

Flood · Jul 16, 2024. The second of three days of hot and humid conditions continued across eastern New York on July 16, 2024. Heat index (feels-like temperatures) reached 95 to 104 degrees across much of the Mohawk and Hudson valleys.||During the afternoon hours, a strong upper level disturbance developed an organized line of thunderstorms which tracked eastward across the region. Widespread severe weather occurred along this line. Wi…

Flood · Jul 29, 2023. Showers and thunderstorms developed along a frontal boundary during the afternoon hours on July 29th across eastern New York. One lone thunderstorm tracked across the Mohawk Valley resulting in numerous reports of downed trees and powerlines as well as a couple of flood reports. Prior to the arrival of these thunderstorms, the combination of hot and humid conditions resulted in heat index values between 95 and 100…

Flood · Jul 14, 2023. A line of strong to severe thunderstorms ahead and along a cold frontal boundary resulted in widespread downed trees and wires and a few reports of flooding across eastern New York during the afternoon and evening hours of July 13, 2023. One injury was reported as a tree fell onto an occupied vehicle. Thousands were left without power across the Capital Region.||Additional isolated to scattered thunderstorms devel…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Schenectady County

If a building in Schenectady County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
