Ahead of any purchase around Shasta Lake, check the Redding flood zone map: FEMA's zone label affects insurance, building rules and resale. This Redding guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Shasta County ArcGIS parcel map.
The Redding flood zone map: start here
The official source is FEMA's Flood Map Service Center: search an address around Shasta Lake, then open the map view for that panel. A tract near Shasta Lake without an address can still be found: zoom in from the nearest road and click the spot.
Pulling up a parcel
Begin with the Shasta County ArcGIS parcel map; it maps each tax parcel around Shasta Lake and Anderson. In and around Shasta Lake, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Shasta Lake, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Anderson may sit some distance off the line on screen. Near Anderson, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Where Redding fits in
Redding is part of Shasta County, California, so its parcels are on the county's map. Redding is also the county seat, so deeds and plats are filed in town. On ground around Anderson, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits out by Shasta Lake generally follows county rules instead.
Decoding the flood zone labels
An AE label carries a published BFE, which plain A zones lack; surveyors near Anderson use that number. For land near Anderson, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Questions to ask before you buy
Ask the listing agent whether the home has flooded on the property near Shasta Lake; an insurance quote early avoids surprises.
When a parcel crosses a boundary
Shasta County touches Lassen County, Modoc County, Plumas County, Siskiyou County, and Tehama County, all with their own assessor records. Acreage along the edge near Anderson may be split in two county records, so look at the adjacent map as well. For a parcel near Anderson, our state page links every bordering county map across California.
Shasta County in a few facts
Redding is the county seat, home to the main records offices. You'll also find Shasta Lake and Anderson, each with its own cluster of lots. Around 180,366 people call Shasta County home (Census Bureau estimate, 2023) spread over some 3,776 square miles. Places such as Sacramento River and Shasta-Trinity National Forest are easy to spot when you zoom out from Anderson.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so open the Shasta County ArcGIS parcel map next for the outline of the tract near Anderson.
Water near Anderson
Small streams around Anderson aren't always studied in detail, so walk the land after rain. Wet ground around Shasta Lake is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Which office to call
Recorded documents for a parcel near Anderson are with the County Recorder, sometimes only in person. Zoning, permits and septic questions near Shasta Lake go to planning, building or health offices, and the answer depends on jurisdiction.
Insurance, lenders and building
In and around Anderson, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Shasta Lake in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.
Sections, lots and bearings
California uses the Public Land Survey System, which means a tract near Shasta Lake is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Anderson odd-sized. Keep the legal description for land near Shasta Lake when you talk to a surveyor.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Anderson, but coverage can be spotty out of town. A printout of the tract near Shasta Lake helps when you meet an owner or agent.
