Case Studies

THIS PAGE IS UNDER CONSTRUCTION
Check back soon for more examples of successful construction projects using soil protection and amendment with compost, erosion control, and more from around the Northwest.

Soil Best Practices:

New Construction
  • Retain and protect native topsoil & vegetation where practical
  • Restore disturbed soils by tilling 2-3" of compost into upper 8" of soil
  • Loosen compacted subsoil, if needed, by ripping to 12" depth
  • Mulch landscape beds after planting
Existing Landscapes
  • Till in compost when re-landscaping
  • Mulch beds with organic mulches
  • Topdress turf with compost

Natural Approaches to Stormwater Management on the Puget Sound Action Team's website shows a variety of private and public projects around Puget Sound. They combine soil best practices with other innovative, attractive, and cost-effective on-site methods for stormwater treatment, detention, and infiltration.

Seattle's Natural Drainage Systems shows before and after photos, specifications, and descriptions of projects from small swale and "raingarden" retrofits to the 130 acre High Point development. All them use compost-amended soil to improve infiltration, clean runoff, and reduce the size or need for stormwater ponds and other detention structures.
