Ahead of any purchase around James Peak Wilderness, look at the Gilpin County flood zone map: FEMA's zone label affects insurance, building rules and resale. What this county guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Gilpin County parcel viewer, at least around Rollinsville.
Where the Gilpin County flood zone map lives
If you're looking near Nevadaville, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Central City with no street number is still easy to locate: zoom in from the nearest road then click the parcel area.
The viewer Gilpin County publishes
Go first to the Gilpin County parcel viewer; it covers each assessed parcel from James Peak Wilderness to Central City. For property near Rollinsville, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Russell Gulch, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Land on the county line
Gilpin County borders Boulder County, Clear Creek County, Grand County, and Jefferson County, and each of those keeps its own parcel map. Acreage along the edge near Rollinsville can be split in two county records, so open the adjacent map as well. For a home near Nevadaville, the Platbookmapper state page links each bordering county map for Colorado.
Zones on the Gilpin County flood zone map
For a parcel near Roosevelt National Forest, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For acreage around Coal Creek, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Offices that can help
Anything recorded against property around Black Hawk come from the County Clerk and Recorder, often with an online index. Questions about what you can build around Nevadaville go to planning, building or health offices, town or county, depending on location.
Lining it up with the parcel map
Where a floodplain cuts across acreage near Russell Gulch, what matters is where the building sits.
Before you lean on the lines
Out toward Rollinsville, the acreage figure is an estimate; only a licensed surveyor can set the real lines on the ground. On ground around Russell Gulch, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Beyond the mapped zones
Creeks and ditches near Black Hawk aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Nevadaville can limit building too; check the National Wetlands Inventory mapper for a first look.
What to request from a seller
If the land is near Nevadaville, ask the listing agent whether the home has flooded before closing; getting a quote early keeps the budget honest.
Where the recorded documents are
When the details count, get the recorded deed from the County Clerk and Recorder; the viewer just points to it, and that holds around Roosevelt National Forest too. For a parcel near James Peak Wilderness, older tracts in the county can trace back through many deeds, so a title company can sort it out before a purchase.
Lenders and permits
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, whether the land is near Russell Gulch or elsewhere in the county. New construction in a floodplain near Black Hawk often needs a floodplain permit; check with the county or town building office early.
Reading the legal description
Colorado is laid out under the Public Land Survey System, which means a tract near James Peak Wilderness 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 sections near James Peak Wilderness can be irregular. Keep the legal description for land near James Peak Wilderness for any title or survey request.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
