Saltese Flats Project - Feasibility Study

(Completed March 2010)

Spokane County Division of Utilities conducted a feasibility study to examine wetland restoration at Saltese Flats. The study considered three project land areas, Options A, B, and C. Option A was approximately 350 acres. Option B included option A plus approximately 170 acres. The third option C, considered approximately 1200 acres including the majority of the Saltese Flats area below the 100-year flood elevation.

Saltese Flats study area options

The study consisted of several phases. The first study phase was to review existing data on the area.

The second phase was an on-site study to determine current conditions including:

  • Existing wetlands and soil types
  • Surface water and groundwater quantity and quality
  • Area climate and topography

 The third phase developed several restoration concept plans for possible restoration. The concept plans considered the three land area options, existing hydrology, and options of reclaimed water additions. Additionally, the concept plans provided ideas for wildlife habitat restoration and public access and education facilities such as trails or buildings.

Overall, the feasibility study found that wetland restoration is feasible at Saltese Flats using natural water and with additions of reclaimed water.
