Johnson Creek runs through Four Seasons for 1,500 feet, part of a large watershed that carries run-off to the Tualatin River. Over the years, our portion of the creek has changed.

• Water levels and velocity have increased. These changes are speeding erosion.  

• Over time, the soil along the creek has been stripped of nutrients and has become compacted.

• Invasive plants are flourishing.

In partnership with Tualatin Soil and Water Conservation District (TSWCD), Four Seasons HOA and Crystalbrook HOA are launching a multi-year project to restore South Johnson Creek through our neighborhood.

Why Restore the Creek?

Restoring the creek through our neighborhood addresses local and regional needs:

• To stop erosion (80% of the creek bank is eroded). 

• Native plantings stabilize creek banks.

• Without them, we have lost a significant amount of our creek banks. 

• Improve habitat for wildlife and pollinators.

• Stabilize the creek for increasing high-water events.

• Reduce invasive species, like reed canary grass, that are spreading along the creek.

• Replace the significant denuded (bare) ground with plants!

TSWCD has prepared an evaluation of our site, describing the conditions and need for restoration. That report is available here,

Restoring the creek is a key priority for the HOA. It is important not only for the many residents who live along the creek, but for all residents of Four Seasons. It is a critical part of our neighborhood and the region.
