How Harrisonburg city floods

Over the last 30 years, standard floods and flash floods from slow-moving weather systems have dominated the flood character of Harrisonburg city, with NOAA recording 17 flood events and 12 flash flood events. Heavy rainfall on saturated soils frequently triggers these incidents, as occurred in May 2018 when scattered thunderstorms dropped moderate to heavy rain on already saturated ground, producing repeated flooding near Harrisonburg as a cold front pushed through the region. Similar moisture-laden boundaries and thunderstorms caused additional flooding and flash flooding in August 2021.

FEMA claims data indicates that property owners outside of high-risk Special Flood Hazard Areas must also pay close attention to potential flood hazards. While Zone A recorded 26 claims with an average water depth of 2 inches and an average payout of $9,765, Zone X recorded 17 claims with an average water depth of 26 inches and an average payout of $32,519. Additionally, Zone X_UNSHADED recorded 5 claims with an average payout of $35,762 and an average recorded water depth of 0 inches, while Zone UNKNOWN accounted for 7 claims averaging 1 inch of water depth and $3,464 in payouts.

From the storm reports

Flood · Aug 16, 2021. A boundary remain draped overhead while a deep southerly flow ushered in plenty of moisture. Showers and thunderstorms resulted in heavy rainfall that led to instances of flooding and flash flooding.

Flash Flood · May 31, 2018. Upslope winds on the east side of the Blue Ridge just north of an approaching warm front aided in producing torrential rainfall and catastrophic flooding in parts of Central Virginia. Rainfall amounts of 4-10 inches occurred north and west of Charlottesville. Later in the evening, heavy rain developed in northern Virginia, with 1-3 inches in the southern and western suburbs of Washington DC, as well as again near…

Flood · May 28, 2018. Scattered thunderstorms developed ahead of a cold front over Maryland during the afternoon hours of May 27th. Moderate to heavy rain on saturated soil produced flooding in portions of northern Virginia. The soils were so saturated that just moderate rain caused more flooding near Harrisonburg during the afternoon of the 28th as the cold front pushed through the region.

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.

Flood insurance in Harrisonburg city

If a building in Harrisonburg city 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.
