At Redmond Ridge, Quadrant Homes fences and protects existing forest as an amenity and stormwater filter. Then they grade to 12 inches below finish grade, stockpiling the topsoil. Next step is to place rock pads for roads and driveways.
Once foundations are in and houses are framed and sided, 14 inches of compost-amended reused soil is placed (to allow for settling to 12-inch finish grade). The compost blend prevents erosion, so work can proceed year-round.
On many sites (here in a Snohomish home remodel) it is more cost effective to till compost into the existing soil. Tilling 2-3 inches of compost into any soil – sand, clay or till – makes planting easier and grows a healthier landscape.
At Shamrock Heights, Cam West Development combines a traditional feel with innovative stormwater methods. Reuse of high-quality site soil, plus mulching, support a vibrant landscape.
At Issaquah Highlands, Port Blakely Communities uses compost blankets for erosion control and cost-effective vegetation establishment on slopes.
Port Blakely also uses compost-amended soils in park and home landscapes, for a high-end, quality product that sells, and attracts future customers too!
