Elevation Certificates in Clark County, WA (2026)
Clark County's position along the Columbia River gives it some of the most scenic real estate in southwest Washington. It also gives it real flood risk. The Columbia River has flooded the Vancouver lowlands, Ridgefield marshlands, and Washougal waterfront properties multiple times over the past century. If your property sits near the Columbia River, the Lewis River, or Lake River, an elevation certificate may be one of the most important documents you can have.
What Is an Elevation Certificate?
An elevation certificate is a standardized FEMA form (Form 086-0-33) completed by a licensed surveyor, engineer, or architect. It records the elevation of your building, including the lowest floor and other critical reference points, and compares those measurements to the Base Flood Elevation (BFE). The BFE is the elevation at which floodwaters have a one percent chance of rising in any given year.
Insurance companies use this comparison to calculate your flood insurance premium through the National Flood Insurance Program (NFIP). If your lowest floor sits well above the BFE, your risk is lower and your premium reflects that. If your building is at or below the BFE, expect higher insurance costs.
Who Needs an Elevation Certificate in Clark County?
Not every Clark County homeowner needs an elevation certificate. You are most likely to need one if:
- Your property is in a FEMA Special Flood Hazard Area, such as Zone AE or Zone A
- Your mortgage lender requires flood insurance as a condition of your loan
- You are applying for a building permit in a flood-prone area within incorporated Vancouver or unincorporated Clark County
- You want to appeal your flood zone designation through a Letter of Map Amendment or Letter of Map Revision
- You are buying a property and want to understand flood risk before closing
High-Risk Flood Areas in Clark County
Clark County has several distinct flood corridors. Knowing which one applies to your property helps you understand what to expect from the elevation certificate process.
Columbia River Flood Zone
The Columbia River defines Clark County's southern boundary. Historic flooding has affected Vancouver waterfront areas, North Portland Harbor, and the lowlands around Frenchman's Bar and Steigerwald Lake National Wildlife Refuge. Properties in Washougal and Camas near the river fall in FEMA AE flood zones. This is the county's highest-risk corridor and the area where elevation certificates are most frequently required.
Lewis River Corridor
The Lewis River enters Clark County from the east and flows toward the Columbia near Woodland. Properties in the La Center and Woodland areas along the Lewis River sit in mapped flood zones. The river has overflowed its banks during major rain events, affecting agricultural and residential land in north county.
Lake River and Ridgefield Area
Lake River connects the Columbia River to Mud Bay and runs near the city of Ridgefield. Low-lying areas adjacent to this channel and the Ridgefield National Wildlife Refuge carry flood risk. Properties in this corridor may require flood insurance and elevation certificates even if they do not appear immediately adjacent to the main channel.
Vancouver Urban Lowlands
Portions of central and east Vancouver in low-lying areas near the Columbia River have historic flood exposure. Columbia Way, the waterfront district, and industrial areas between Interstate 5 and the river have been affected by major Columbia River flood events. Residential properties in these zones should check FEMA maps carefully.
