Look up the Marion County flood zone map step by step
Open the FEMA Flood Map Service Center and type a county street address, say one in Indianapolis. If a tract near Crows Nest has no street number yet, search the nearest road and pan to it. If the PDF panel for Marion County is hard to read, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, so you can see if the shading reaches a house near Crows Nest. Switch to the Marion County parcel viewer and track down the same tract near Crows Nest. Laying the county parcel outline beside the FEMA shading shows if a homesite near Crows Nest sits above or inside the zone.
Finding the tract on the Marion County map
Marion County publishes its parcels on the Marion County parcel viewer, free to use for a lot in Crows Nest or a tract near Speedway. Use the search box for an address in Crows Nest or a parcel number, or simply zoom in and click a tract near Speedway. If the official address for the Marion County, IN map ever changes, our directory page carries the current link for Crows Nest and the rest of the county.
Reading the zones on a Marion County flood map
For a lot in Indianapolis, the label matters more than the color: A and V zones are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. A surveyor working near Indianapolis uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. Land near Crows Nest in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded Zone X near Crows Nest is minimal risk.
Waterfront parcels near Crows Nest
In Marion County, look closest at tracts along White River, Fall Creek and Geist Reservoir. On many tracts near Indianapolis, the zone covers the low ground by the water while the homesite near the road is outside it. A creek near Crows Nest that shows no detailed zone, which is why it is worth walking the ground after a heavy rain.
What a flood zone means for a Marion County buyer
Insurance is the practical stake for a Marion County buyer. If a house near Crows Nest sits in a Special Flood Hazard Area and secures a loan from a federally regulated or insured lender, the lender must require flood coverage, as long as Marion County or the town participates in the NFIP. For a county home in shaded or unshaded X, coverage is optional; pricing a policy for land near Crows Nest is still worth a call. Where a structure near Indianapolis looks higher than the shading suggests, the landowner can ask FEMA for a Letter of Map Amendment (LOMA); a surveyor near Crows Nest can supply the elevation data. Placing fill on low ground near Indianapolis frequently requires a permit and an elevation check; the county floodplain administrator can say what applies.
