Environmental Rules in Bellingham, WA

If you live in Bellingham or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Bellingham has 5 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.

Flood Elevation Requirements

New and substantially improved homes in Bellingham's mapped flood hazard areas must elevate the lowest floor at least one foot above the FEMA base flood elevation.

Key details: Freeboard required: 1 foot above BFE. Applies to: new construction, substantial improvement. Data source: FEMA FIRM maps. Permit needed: development permit, Public Works. Max fine: $1,000 misdemeanor.

Building without the required elevation or the development permit is a misdemeanor punishable by up to $1,000, plus a civil penalty of up to $100 per day until the violation is corrected.

Boat Dock Permits

Bellingham exempts small private docks from a shoreline permit, but larger docks need a shoreline substantial development permit under the city's state-approved Shoreline Master Program.

Key details: Saltwater exemption cap: $2,500 fair market value. Freshwater exemption cap: $10,000 fair market value. 5-year rule: Later work over $2,500 counts as new. Governing framework: Shoreline Master Program, RCW 90.58.

Building or expanding a dock over the value threshold without a shoreline substantial development permit is a violation of the Shoreline Master Program, enforceable by the city apart from any separate building or Army Corps permit requirements.

Flood Zones

Bellingham requires new and substantially improved residential structures in FEMA-mapped flood hazard areas to have the lowest floor elevated at least one foot above base flood elevation, under the city's floodplain construction ordinance.

Key details: Elevation requirement: 1 foot above base flood elevation. Permit required: before any construction in flood hazard area. Misdemeanor fine: up to $1,000. Civil penalty: up to $100 per day. Governing chapter: BMC Title 17.76, Construction in Floodplains.

Building without a floodplain development permit or below the required elevation is a misdemeanor punishable by up to $1,000, plus a civil penalty of up to $100 per day of continued noncompliance, collected by city civil action.

Erosion Control

All grading citywide in Bellingham must include erosion containment, and any land-disturbing work proposed between October 1 and May 31 needs an approved wet-weather erosion control plan.

Key details: Applies to: All city grading activity. Wet-weather window: Oct 1 – May 31. Requirement: Ecology Manual BMP plan. Lake Whatcom watershed: Total seasonal ban applies.

Grading without required erosion controls is a misdemeanor with fines up to $1,000 per day, plus stop-work orders and city-billed restoration costs (BMC 16.70.140).

Stormwater Management

Bellingham requires city approval under BMC Ch. 15.42 before any new development, redevelopment, or land-disturbing activity that adds impervious surface, enforcing stormwater quality and quantity controls citywide.

Key details: Approval required: Before new dev/redevelopment. Max infraction fine: $500/day (BMC 15.42.100). Special protection area: Lake Whatcom Basin One. Standard used: DOE Stormwater Manual BMPs. Administered by: Public works director.

Violating BMC Ch. 15.42 is an infraction under BMC 15.42.100, punishable by a stop-work order and/or a fine of up to $500 per day; each day of continued or repeated violation is a separate violation.

This is not one of those rules that cities tend to ignore. Bellingham actively enforces its stormwater management requirements.
