How Kent County floods

Flash flooding from heavy rainfall dominates the flood history of Kent County, which recorded 21 flash flood events alongside coastal flooding, tropical storms, and storm surges over the last 30 years. Recent events illustrate these hazards, such as an October 2021 coastal flood that brought moderate tidal flooding to the upper eastern shore of the Chesapeake Bay due to a prolonged onshore flow, and a September 2021 flash flood driven by thunderstorms that produced rainfall totals as high as 3 to 5 inches.

National Flood Insurance Program records show varying impacts across different zones. Zone A accounts for the vast majority of claims with 263 filings, averaging a payout of $30,969 and an average recorded water depth of 7 inches. Properties in zones categorized as X, X_Shaded, and X_Unshaded also recorded claims, with average payouts ranging from $15,994 to $39,222 and average water depths of 0 to 3 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties in Zone A, which experience the highest frequency of claims and deepest average water levels, as well as coastal parcels exposed to tidal flooding from the Chesapeake Bay and low-lying areas vulnerable to heavy rainfall.

Where the flood claims came from

10% of Kent County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

From the storm reports

Coastal Flood · Jan 10, 2024. A strong system affected the region with steady southerly flow pushing water up into coastal communities both along the ocean and within the Delaware River/Bay and Chesapeake Bay. Water levels on the tidal Delaware River were higher due to 2 to 4+ inches of rainfall.

Coastal Flood · Oct 29, 2021. Strong high pressure located in eastern Canada and slow moving low pressure approaching from the southeastern states resulted in a prolonged onshore flow along the Middle Atlantic coast. Moderate tidal flooding occurred along the upper eastern shore of Chesapeake Bay on the night of October 29.

Flash Flood · Sep 23, 2021. Thunderstorms produced locally heavy rain in northeastern Maryland on the morning of September 23. Rainfall totals were as high as 3 to 5 inches.

Flash Flood · Aug 6, 2020. An impulse moving along a stalled boundary draped across the region, in combination with moisture left over from Hurricane Isaias, produced severe thunderstorms with damaging winds and flooding rains over the eastern shore of Maryland during the early morning hours of August 6th.

Flood insurance in Kent County

If a building in Kent 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.
