Before an offer near Markleeville, look at the Alpine County flood zone map: FEMA's zone label affects insurance, building rules and resale. Covered here for Alpine County: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Where the Alpine County flood zone map lives
For acreage around Humboldt–Toiyabe National Forest, start with FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Rural land near Markleeville with no street number can still be found: zoom in from the nearest road and click inside the land.
The viewer Alpine County publishes
Begin with the Alpine County ArcGIS parcel map; it includes every tax parcel from Bear Valley to Humboldt–Toiyabe National Forest. Out toward Fredericksburg, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Bear Valley, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
On site with the map
Most viewers work in a phone browser, useful out on a road near Humboldt–Toiyabe National Forest, but coverage can be spotty out of town. A printout of the tract near Humboldt–Toiyabe National Forest helps when you meet an owner or agent.
Questions to ask before you buy
Ask the seller whether the home has flooded on the property near Humboldt–Toiyabe National Forest; getting a quote early keeps the budget honest.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so a fence near Humboldt–Toiyabe National Forest often sits some distance off the line on screen. Out toward Lake Alpine, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Reading A, AE and X
Zone AE comes with a base flood elevation, while plain Zone A does not; that elevation drives building rules near Stanislaus National Forest. For land near Humboldt–Toiyabe National Forest, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Places you'll see on the map
Markleeville is the county seat, where most land records are kept. You'll also find Alpine Village, Bear Valley, Fredericksburg, and Kirkwood. Around 1,141 people live in Alpine County (Census estimate, 2023) on about 738 square miles. Places such as Eldorado National Forest are easy to spot when you zoom out.
Water near Alpine Village
Low-lying fields near Humboldt–Toiyabe National Forest may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Humboldt–Toiyabe National Forest can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Deeds, plats and who keeps them
When the details count, get the recorded deed from the County Recorder; the parcel map near Humboldt–Toiyabe National Forest only summarizes it. For land near Humboldt–Toiyabe National Forest, use the document number shown in the record panel and the lookup takes minutes.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Alpine County ArcGIS parcel map for the outline of the tract near Alpine Village.
When a parcel crosses a boundary
Alpine County meets Amador County, Calaveras County, El Dorado County, Mono County, and Tuolumne County, all with their own assessor records. A tract near the line by Humboldt–Toiyabe National Forest may be split in two county records, so open the adjacent map before you assume the acreage. Around Humboldt–Toiyabe National Forest, our state page links every neighboring county map for California.
