FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Eugene, OR.

Full Breakdown

6709 apply. 6706 requires a development permit, applied for on city forms with scaled plans showing existing and proposed structures, fill, storage, and drainage. 6707(2)(c)3. 6707's general standards require new construction and substantial improvements to be anchored against flotation and lateral movement, built with flood-damage-resistant materials and methods, and designed so electrical, heating, and other mechanical equipment sits at least one foot above the base flood elevation. Anyone who wants to alter or relocate a watercourse first has to notify the city, the Department of Land Conservation and Development, and other agencies, maintain the channel's flood-carrying capacity, and route a Letter of Map Revision through the Federal Insurance Administration. 6709.

Violations & Fines

Building or filling in a mapped special flood hazard area without the EC 9.6706 development permit, or failing to meet the anchoring, materials, and elevation standards in EC 9.6707, is a Land Use Code violation enforceable under Chapter 9's general administration and enforcement provisions, EC 9.0000 through 9.0280; because the floodplain rules exist to keep Eugene's FEMA flood insurance eligibility intact, unpermitted floodplain work can also jeopardize a property owner's ability to obtain federally backed flood insurance.

Frequently Asked Questions

Do I need a permit to build in a Eugene floodplain?

Yes. EC 9.6706 requires a development permit before any construction, fill, or other development begins within a special flood hazard area shown on the city's adopted Flood Insurance Rate Maps, panels 0619 through 1650, and the application must show existing and proposed structures, drainage, and elevations.

How high do utilities have to sit above the flood level in Eugene?

EC 9.6707(1)(d)2 requires electrical, heating, ventilation, plumbing, and similar equipment to be elevated at least one foot above the base flood elevation, with a narrow exception spelled out in the same subsection.

Can a non-residential building in a Eugene floodplain skip elevating and use floodproofing instead?

Yes, but only with certification. EC 9.6706(2)(c) requires a registered Oregon professional engineer or architect to certify that the proposed floodproofing methods meet the criteria in EC 9.6707(2)(c)3 for non-residential structures.

What if a property can't meet Eugene's floodplain construction standards?

The only path is the variance procedure set out at EC 9.6709, separate from the standard development permit process in EC 9.6706.
