From the storm reports

Flash Flood · Aug 1, 2022. Heavy rain fell over portions of north-central Saguache County producing flooding and closing down CO Hwy 114 for several hours.

Flash Flood · Jul 24, 2021. Increases in moisture and instability on this day supported thunderstorm development over and near the mountains, and also around the I-25 and Highway 50 corridors. Stronger development did occur across Pueblo county, where heavy rainfall with flash flooding and damaging winds were observed.

Flash Flood · Aug 2, 2021. Slow moving thunderstorms developed over the mountains, as the monsoon plume remained in place on this day. With the heavy rain that stemmed from these thunderstorms along with high antecedent soil moistures from rainfall over the past several days, the flash flood threat remained high with a few reports of flash flooding noted near the higher terrain.

Flash Flood · Jul 5, 2007. Heavy thunderstorm rains produced flash flooding around Buena Vista in Chaffee County and west of Saguache in Saguache County.

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Saguache County

If a building in Saguache 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.
