FLOODPLAIN DEVELOPMENT APPLICATION (SVMC 21.30)
A floodplain development permit is required before any construction or development can begin in an area
designated as a special flood hazard area (SFHA), also known as the 100 -year floodplain. The permit is for all
structures including manufactured homes and for all development including fill and other activities. Please refer to
the City of Spokane Valley Municipal Code (SVMC) Section 21.30
Note - The degree of flood protection required by the City code is considered reasonable for regulatory purposes
and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions and
flood heights may be increased by manmade or natural causes. Due to this, land located outside the areas of
special flood hazard, or uses permitted within the special flood hazard areas, may experience flooding or flood
damages (SVMC 21.30.060).
Before you fill out your floodplain application please:
1. Carefully review the items listed below. The information is needed to meet the National Floodplain Insurance
Program (NFIP) requirements.
2. Contact Deanna Griffith, Administrative Assistant for the Floodplain Administrator in the Community
Development Department (509-720-5301) for help in filling out the application.
3. Complete the application and prepare the drawings for submittal. Once a complete Floodplain Development
Application and associated fee has been submitted to the Spokane Valley Permit Center, the City will review
the application materials. The City may request additional information or issue a decision on the permit.
During construction, elevation certifications of finished floors, equipment, or other elements of the project may
be required. The required certification forms will be provided to you along with the permit. These will require
completion by a Washington State registered land surveyor and be turned in to the City before proceeding
with work or securing occupancy.

❑ Elevation of a) lowest floor (including basement) and b) highest ground surface adjacent to the structure
(Note: Critical facilities have the lowest floor elevated three feet above BFE or to the height of the 500 -

3. ❑ Hydrologic and hydraulic analyses, performed in accordance with standard engineering practice, which
supports the water surface elevations and floodplain/floodway widths both before and after the project is
completed. If applicable, the analyses shall demonstrate that there is no net loss of flood storage or
infiltration capacity for areas within a compensatory storage area.
4. ❑ For all new and substantially improved buildings: An elevation certificate (FEMA Form 81-31), completed
by land surveyor licensed in the State of Washington. (Not required for structures in "A" zones that don't have
base flood elevations.)
5. ❑ If base flood elevation data has not been provided or is not available from an authoritative source, it shall
be generated by a land surveyor licensed in the State of Washington.

property owners for said increase in base flood elevations.
9. ❑ If development is proposed within a mapped floodway a "no -rise" certification and supporting
documentation, completed by a registered professional engineer, must be submitted prior to issuance of a

provisions of this title and relevant local, state and federal regulations.
❑ In all instances of locating utilities and other installations in floodway locations, project design must
incorporate flood -proofing, certified by a professional civil engineer registered as such by the State of
Washington, to be capable of withstanding 100 -year flood flows and velocities.
❑ For any works that impound water, the applicant shall provide documentation of easements, flowage
rights or ownership of the impoundment area and certification by a professional civil engineer, registered
as such by the State of Washington, that the works will cause no increase in the 100 -year flood elevation
