Before you buy or build near Tongass National Forest, pull up the Ketchikan Gateway Borough flood zone map: the zone on that map shapes insurance, building rules and resale. Covered here for Ketchikan Gateway Borough: finding the address on FEMA's map, reading the zone codes, and pairing it with the Ketchikan Gateway County Portico map.
The Ketchikan Gateway Borough flood zone map: start here
If you'd rather pan and zoom, use the National Flood Hazard Layer viewer, where zone shading sits over a photo base, whether the land is near Loring or elsewhere in the borough. Rural land near Clover Pass with no street number is still easy to locate: zoom in from the nearest road and click the spot.
Pulling up a parcel
Property in and around Ward Cove can be looked up on the Ketchikan Gateway County Portico map, which opens without registering. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, whether the land is near Tongass National Forest or elsewhere in the borough. If the land is near Clover Pass, save the parcel ID from that panel; each clerk in the borough will want it.
Zones on the Ketchikan Gateway Borough flood zone map
For land near Ward Cove, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For property near Misty Fjords National Monument, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Ketchikan, so load it before you lose signal. A saved image of the lot near Saxman and its lines is a good backup.
Before you lean on the lines
With a lot near Clover Pass, acreage on the record is an estimate; just a licensed surveyor sets the real boundary on the ground. Records update in batches, so a recent sale near Ketchikan might lag behind.
Beyond the mapped zones
Small streams around Clover Pass may not have detailed mapping, so walk the land after rain. Wetlands near Misty Fjords National Monument can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Offices that can help
For assessment questions about property around Ward Cove go to the borough assessor, the office behind the parcel record. Zoning, permits and septic questions near Tongass National Forest go to planning, building or health offices, town or borough, depending on location.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Ketchikan Gateway County Portico map too to confirm you have the right parcel near Ward Cove.
How land is described here
Alaska is laid out under the Public Land Survey System, so rural legal descriptions near Ward Cove cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Tongass National Forest vary in size. Copy the legal description from the record for the parcel near Ward Cove for any title or survey request.
Questions to ask before you buy
If you're looking near Saxman, ask the listing agent about past flood claims before closing; an insurance quote early keeps the budget honest.
Land on the borough line
Ketchikan Gateway Borough touches Prince of Wales-Hyder Census Area and Wrangell City and Borough, and each of those keeps its own parcel map. A tract near the line by Clover Pass may show up in two borough records, so look at the adjacent map as well. Out toward Misty Fjords National Monument, our state page links each neighboring borough map across Alaska.
Money questions tied to the zone
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, flood insurance is generally required in communities in the NFIP, whether the land is near Ketchikan or elsewhere in the borough. New construction in a floodplain near Saxman can trigger elevation rules; check with the borough or town building office early.
