How Goliad County floods

Flash flooding from severe weather events dominates the flood history of Goliad County, accounting for 38 recorded events and 1 death over the last 30 years, alongside impacts from 1 hurricane. Significant weather events include May 2013, when 7 to 9 inches of rain caused flash flooding across the area, and August 2017, when Major Hurricane Harvey brought minor to moderate damage to the city of Goliad.

NFIP historical claims data shows losses across multiple zones. Zone UNKNOWN recorded 7 claims with an average payout of $15,343 and an average water depth of 20 inches. Zone A recorded 6 claims with an average payout of $30,315 and an average water depth of 2 inches. Zone X recorded 2 claims with an average payout of $44,707 and an average water depth of 0 inches, while Zone X_UNSHADED recorded 1 claim with an average payout of $45,000 and an average water depth of 52 inches.

Homeowners and real estate agents with properties in unmapped or low-to-moderate risk areas should pay close attention to these patterns, as significant payouts and severe water depths have occurred outside of standard high-risk zones.

From the storm reports

Hurricane (Typhoon) · Aug 26, 2017. Major Hurricane Harvey impacted the Middle Texas coast on August 25th and 26th. Harvey was the first category 4 hurricane to strike Texas since Hurricane Carla in 1961. Harvey severely affected the cities of Rockport, Fulton, Port Aransas, Aransas Pass, Ingleside, Holiday Beach, and Refugio. Minor to moderate damage occurred in cities of Portland, Corpus Christi, Seadrift, Woodsboro, Port Lavaca, Goliad, and Victo…

Flash Flood · Apr 22, 2015. Several supercells developed and tracked east-southeast along a nearly stationary front stretching from the Hill Country to South Texas into the central Gulf of Mexico. These storms contained very large hail, up to tennis ball size near Austwell, and very strong winds greater than 60 mph. Wind damage and flash flooding occurred with these severe thunderstorms also.

Flash Flood · Apr 27, 2013. A strong upper level disturbance moved out of northern Mexico into South Texas during the evening hours of April 27th and early morning hours of April 28th. Numerous thunderstorms moved into the western Brush Country during the evening hours. Very heavy rainfall with these storms produced flooding in the Laredo area. Another area of strong to severe thunderstorms moved through the Victoria Crossroads during the ea…

Flash Flood · May 25, 2013. Deep atmospheric moisture was in place over South Texas during the morning hours on May 25th. A slow moving upper level disturbance moved into the area from the west producing scattered to numerous thunderstorms over the northern Coastal Bend into the Victoria Crossroads. Showers and thunderstorms trained over the same areas into the early afternoon hours. Rain amounts between 7 and 9 inches caused flash flooding…

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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 Goliad County

If a building in Goliad 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.
