Looking at a lot near Colfax? Checking the Newton flood zone map reveals whether it sits in a FEMA flood zone, and no account is needed. In this Newton guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Jasper County Beacon site.
Checking the Newton flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: search an address around Lambs Grove, and choose the dynamic map. A tract near Baxter without an address can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Lots and tracts near Reasnor are published on the Jasper County Beacon site, which opens without registering. For acreage around Oakland Acres, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Oakland Acres, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Sections, lots and bearings
Iowa uses the Public Land Survey System, which means a tract near Reasnor is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Reasnor odd-sized. Copy the legal description from the record for the parcel near Lambs Grove before you request a deed or survey.
A short flood checklist
Ask the seller for any Elevation Certificate on the property near Oakland Acres; getting a quote early keeps the budget honest.
Newton, IA: the basics
Newton is part of Jasper County, Iowa, which means parcel data comes from the county. Newton is also the county seat, so deeds and plats are filed in town. If you're looking near Oakland Acres, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits out by Reasnor usually answers to county rules instead.
Decoding the flood zone labels
Zone AE includes a base flood elevation (BFE), which plain A zones lack; surveyors near Lambs Grove use that number. Out toward Kellogg, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Low spots and local drainage
Low-lying fields near Kellogg may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Lambs Grove is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Jasper County Beacon site too to see exactly which lot near Oakland Acres you're looking at.
Limits of the parcel data
Acreage on the record is an estimate; only a licensed surveyor can set the real corners for a parcel near Kellogg. Closer to Oakland Acres, records update in batches, so a deed recorded last month might lag behind.
Getting your bearings
Newton holds the county offices, where most land records are kept. You'll also find Lambs Grove, Kellogg, Reasnor, and Colfax, where town lots give way to larger tracts. Roughly 37,919 people call Jasper County home (Census Bureau estimate, 2023) on roughly 730 square miles. Jasper County was organized in 1846, so old deeds can run back a long way. Places such as Skunk River help you orient on the aerial around Reasnor.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, and that holds around Colfax too. Building or adding on near Colfax in a mapped zone can trigger elevation rules; call the permitting office early.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Kellogg are filed with the County Recorder. Long-held tracts near Baxter can go back through a long string of deeds, so a title company is worth hiring before a purchase.
Neighboring parcel maps
Jasper County borders Mahaska County, Marion County, Marshall County, Polk County, and Poweshiek County, all with their own assessor records. Acreage along the edge near Kellogg can be split in two county records, so open the neighboring map as well. If you're looking near Baxter, the Platbookmapper state page links every bordering county map for Iowa.
