Hillside landscape in Seattle is redesigned with additional support, patios, and decking.

This hillside stabilization project is on Perkins Lane in Seattle, WA. The homeowners had a water main break on the hill above their home causing thousands of gallons of water to damage and undermine their entry steps, retaining wall, parking strip, driveway and foundation. This house was built overlooking Puget Sound with little usable outside space. The garage is being converted into a library and the driveway was seldom used for any vehicles. There was no defined lower yard access down the slope. A large maple was damaged during the Nisqually earthquake and was leaning towards the house. The homeowners decided to recreate the landscape to better suit their needs.

Environmental Construction Landscape Project:

• The parking strip was reset to accommodate vehicles.
• The hillside below the edge of the house was engineered to support the patio and slope above.
• The driveway was removed and replaced with patios and decking.
• The timber retaining wall was shored up with rock outcroppings and plantings. Hillside access was created from the street to the new patio area and from the patio area to the lower yard.
• Hillside access was created from the street to the new patio area and from the patio area to the lower yard.
• An irrigation system was installed to hydrate the mostly native plantings.
