All consumer fireworks are banned within the City of Kennewick. The Washington State Fireworks Law at Chapter 70.77 RCW (the State Fireworks Act) authorizes cities under RCW 70.77.395 to adopt local ordinances more restrictive than the state baseline, and Kennewick has used that authority to prohibit the sale, possession, and discharge of consumer fireworks city-wide. Aerial and explosive fireworks are illegal throughout Washington under RCW 70.77.136 and RCW 70.77.401 regardless of local opt-in.

Heavy RestrictionsBrush Clearance
Kennewick regulates dried grasses, dead brush, and unmaintained vegetation through Kennewick Municipal Code (KMC) Chapter 9.48 (Weed Hazards), which declares any grass, weed, or vegetation that has grown and died or is unirrigated and exceeds 12 inches in length to be a public nuisance. KMC 9.44 (Substandard / Unfit Buildings) addresses fire-hazard vegetation on developed lots. Code Enforcement may issue a 20-day notice to abate weeds before pursuing civil or criminal infractions. The Eastern Washington shrub-steppe gives Kennewick moderate seasonal fire risk that drives summer enforcement.

Heavy RestrictionsWildfire Zones
Kennewick sits in the Columbia Basin shrub-steppe of Eastern Washington, an environment of moderate wildfire risk. Washington has not adopted IFC Chapter 49 (Wildland-Urban Interface Areas) or California-style Wildfire Hazard Severity Zones statewide, and Kennewick has no city-designated WHSZ map. Wildfire policy comes from the Benton County Community Wildfire Protection Plan (CWPP, updated 2018 via WA DNR), Benton County Fire District No. 1 (which serves Kennewick), and DNR's statewide Wildfire Hazard and Risk Mapping under RCW 76.04. The annual Eastern Washington Industrial Fire Precaution Level (IFPL) and DNR burn restrictions drive the seasonal rules.
