Before you buy or build near Scranton, pull up the Dunmore flood zone map: a mapped flood zone changes insurance, permits and resale. This Dunmore guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Lackawanna County GISViewer Parcels.
Checking the Dunmore flood zone map step by step
Start with FEMA's Flood Map Service Center: type an address near Scranton, and choose the dynamic map. A tract near Olyphant without an address is still easy to locate: zoom in from Interstate 84 and click inside the land.
Where the parcel data lives
Go first to the Lackawanna County GISViewer Parcels; it includes every assessed parcel around Throop and Dickson City. When a rural tract has no street number, follow Interstate 84 on the aerial and select the outline. Near Olyphant, write down the parcel ID while you have it open; every office in the county will want it.
Dunmore and the county around it
Dunmore is part of Lackawanna County, Pennsylvania, which means parcel data comes from the county. For a home near Throop, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Olyphant usually falls under county rules, not municipal ones.
When a parcel crosses a boundary
Lackawanna County touches Luzerne County, Monroe County, Susquehanna County, Wayne County, and Wyoming County, all with their own assessor records. Acreage along the edge near Throop may show up across two assessors' files, so open the adjacent map as well. For acreage around Throop, the Platbookmapper state page lists each neighboring county map across Pennsylvania.
The paper trail behind a parcel
The map is an index, not the title: deeds, plats and easements covering ground around Jessup sit with the Recorder of Deeds. Long-held tracts around Olyphant may go back through several deeds, and a title company earns its fee on a real sale.
Getting your bearings
Scranton serves as the county seat, where most land records are kept. Other places on the map include Throop, Olyphant, and Dickson City, where town lots give way to larger tracts. Around 216,123 people call Lackawanna County home (Census estimate, 2023) across roughly 459 square miles. The county was formed in 1878, and some chains of title near Scranton are long. Features like Lake Scranton and Lackawanna State Park help you orient on the aerial around Olyphant.
Zones on the Dunmore flood zone map
Zone AE carries a published BFE, while plain Zone A does not; that elevation drives building rules near Throop. If you're looking near Jessup, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Lackawanna County GISViewer Parcels to see exactly which lot near Throop you're looking at.
Low spots and local drainage
Low-lying fields near Scranton aren't always studied in detail, so walk the land after rain. Wet ground around Blakely is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near Throop, so load it before you lose signal. A screenshot of the parcel near Jessup with its ID is a good backup.
Money questions tied to the zone
For a tract near Olyphant, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Throop in a mapped zone can trigger elevation rules; check with the county or town building office early.
Which office to call
For assessment questions about property around Blakely belong with the county assessment office, which maintains the tax roll. Questions about what you can build around Olyphant go to planning, building or health offices, depending on whether the land is inside town limits.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate on the property near Blakely; getting a quote early keeps the budget honest.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so a fence near Blakely can sit some distance off the line on screen. Near Throop, records update in batches, so a deed recorded last month can take weeks to appear.
