How Pike County floods

River overflow along the Mississippi and flash flooding from storms dominate the flood profile of Pike County, Missouri, which recorded 14 flood events and 14 flash flood events, resulting in 1 death, over the last 30 years. Heavy precipitation systems frequently trigger rapid runoff and high river stages, as occurred during a strong spring storm system on April 29, 2017, that brought multiple rounds of thunderstorms, over nine inches of rain in some locations, and historic flooding along river tributaries. A similar event occurred on May 1, 2013, when the Mississippi River remained in major flood levels along the border of Marion and Pike counties, resulting in closed roads and flooded farmland.

National Flood Insurance Program records indicate that flood impacts are heavily concentrated in designated high-risk areas. Zone A accounts for the vast majority of claims with 847 filings, averaging a $12,177 payout and an average recorded water depth of 17 inches. Properties outside standard high-risk zones also experience occasional water damage, including claims in Zone X where water depths averaged 44 inches. Homeowners and real estate agents with properties located in Zone A and near major waterways should pay the most attention to flood risk and mitigation requirements.

From the storm reports

Flash Flood · May 29, 2019. Forecast area was in the warm sector ahead of a strong cold front. Storms developed across the region, some of which produced severe storms.

Flash Flood · Apr 29, 2017. A strong spring storm system brought multiple rounds of thunderstorms and heavy rain to the southeast half of Missouri during the weekend of April 29th-30th. Rainfall totals surpassed nine inches in some locations and this led to flash flooding and historic flooding along some of the tributaries of the Missouri and Mississippi Rivers. Areas along the Meramec River were especially hard hit as new records were set…

Flash Flood · Jun 21, 2015. A cold front moved into the region and stalled out, triggering showers and thunderstorms. A number of thunderstorms developed across northern Missouri and west central Illinois. Heavy rain from the storms caused flash flooding across the region.

Flood · Apr 12, 2013. Heavy rain caused the Mississippi River to rise to major flood levels at several locations along the Missouri border. Damage was limited to some closed roads and agricultural lowlands. The river continued in flood into May.

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 Pike County

If a building in Pike 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.
