Land Use and Zoning Washington 4 Minutes Read · published March 01, 2026 Flag of Washington

Spokane Valley, Washington regulates building and land use in floodplains, wetlands, and the public display of signs through its municipal rules and permitting process. This guide summarizes how floodplain and wetland protections interact with zoning and sign controls, who enforces them, and practical steps to apply for permits or challenge enforcement decisions in Spokane Valley.

Floodplain and Wetland Rules

Development in mapped floodplains and regulated wetlands is limited to reduce risk to life, property, and critical habitat. Spokane Valley relies on its municipal code and federal/state mapping to define regulated areas; local permits may require elevation certificates, mitigation plans, or avoidance measures. Consult the city code for specific definitions, mapping references, and standards for fill, grading, and habitat protection Spokane Valley Municipal Code[1].

Ask planning staff early to confirm whether a site is in a regulated floodplain or wetland.

Signs Regulations

Sign size, placement, illumination, and temporary display rules are governed by Spokane Valley zoning and sign chapters; many standards aim to protect safety, sightlines, and neighborhood character while allowing business identification. Sign permit requirements, measurement rules, and prohibited sign types are listed in the city code and in permit guidance from the planning office City of Spokane Valley Planning & Development[3].

Temporary signs often have different rules and limited display durations.

Permits, Approvals, and When Federal/State Maps Apply

For floodplain work, Spokane Valley typically uses FEMA flood maps as the baseline for regulatory floodplain boundaries; projects may require review if they intersect mapped special flood hazard areas or if state wetland rules are implicated. Floodplain development permits, compensatory mitigation, or state approvals may be required depending on scope and location FEMA Flood Map Service Center[2].

  • Permit types: building permit, sign permit, floodplain development permit, and land-disturbing activity permits.
  • Review timelines: variable by project complexity; early pre-application meetings are recommended.
  • Conditions: elevation, anchoring, mitigation, and construction standards may be imposed.

Applications & Forms

The city issues permit application forms and checklists for building, sign, and land-disturbing permits through the Planning and Permit Center; fees and exact submittal checklists are on official city permit pages.
