Weighing a property around Hillsborough? The Burlingame flood zone map tells you whether FEMA puts it in a high-risk zone, and no account is needed. What this Burlingame guide covers: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is.
The Burlingame flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near South San Francisco, then open the map view for that panel. Rural land near Hillsborough with no street number is still easy to locate: zoom in from the nearest road and click inside the land.
Where the parcel data lives
Property in and around Millbrae appear on the San Mateo County parcel viewer, free to use and open without a login. For a tract near South San Francisco, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Millbrae, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Burlingame and the county around it
Burlingame lies within San Mateo County, California, and the county assessor maps its lots. For a home near Hillsborough, City or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits out by Millbrae usually follows county rules rather than the town's.
Reading A, AE and X
If the land is near Hillsborough, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a home near Brisbane, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Getting your bearings
Redwood City serves as the county seat, where most land records are kept. Other places on the map include Millbrae, Hillsborough, San Mateo, and San Bruno, where town lots give way to larger tracts. Roughly 726,353 people live in San Mateo County (Census estimate, 2023) across about 449 square miles. Features like Don Edwards San Francisco Bay National Wildlife Refuge help you orient on the aerial around San Bruno.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the San Mateo County parcel viewer to confirm you have the right parcel near Millbrae.
Water near San Bruno
Small streams around Brisbane aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Millbrae can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near San Bruno are filed with the County Recorder. For property near San Bruno, have ready the book and page shown in the record panel so staff can find the deed fast.
Money questions tied to the zone
Around South San Francisco, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Hillsborough in a mapped zone usually means extra permit review; ask the local floodplain administrator before you plan.
How land is described here
California uses the Public Land Survey System, so rural legal descriptions near San Mateo cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Brisbane vary in size. Keep the legal description for land near San Mateo when you talk to a surveyor.
When a parcel crosses a boundary
San Mateo County borders Alameda County, San Francisco County, Santa Clara County, and Santa Cruz County; every one of them runs a separate parcel map. Acreage along the edge near San Mateo can show up in two county records, so look at the neighboring map as well. For land near Millbrae, the Platbookmapper state page lists each neighboring county map for California.
A short flood checklist
Request whether the home has flooded on the property near Hillsborough; getting a quote early avoids surprises.
Offices that can help
Deeds, mortgages and recorded plats for land near San Bruno sit in the index kept by the County Recorder, usually searchable by name or document number. Building or septic questions for a lot near Hillsborough go to planning, building or health offices, and the answer depends on jurisdiction.
Burlingame: common questions
What is a base flood elevation in Burlingame?
In most cases, a BFE near Hillsborough tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
Where can I see the Burlingame flood zone map for free?
In most cases, search the address near Hillsborough on FEMA's Flood Map Service Center, and the zone code appears on the map.
Is Zone X safe from flooding near Brisbane?
In most cases, Zone X near South San Francisco means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
What is a LOMA in Burlingame?
Generally, FEMA's LOMA process is the usual route when a building near San Bruno sits above the base flood elevation; a surveyor's elevation data supports it.
Can I print the parcel map for land near Millbrae?
Most viewers have a print or export tool, and it's worth keeping the parcel ID visible for land near San Bruno.
