Compost-Amended Soil Requirements

Incorporating compost into soils that are disturbed or damaged by human development (such as typical construction practices) has many benefits for the overall health of the soil ecosystem including: improved water retention, increased infiltration rates, greater binding ability, pH stabilization, and micronutrient enrichment. These micro-level soil benefits in turn, lead to significant community benefits on a macro-level, such as: improved water conservation, reduced non-point source pollution (through enhanced natural management of agricultural and urban stormwater runoff), reduced erosion and stream sedimentation, and healthier plant life, reducing fertilizer and pesticide needs. As a result, many public and private entities are implementing rules and strategies that improve soil quality by using compost to ultimately reduce maintenance issues and associated costs.

 

Model Policies

Denver, Colorado – Compost Amended Soil

Denver is one of several communities to mandate the use of compost in disturbed soil and new landscaping as a means of improving the ability of soil to conserve and manage water. As water stress and pressures have become increasing concerns in western US states, simple, cost-effective solutions such as requiring a minimum amount of organic matter...

Greeley, Colorado – Compost Amended Soil

The City of Greeley, Colorado has enforced water restrictions for over a century, but in the early 2000s decided to make the use of compost mandatory. By requiring a specific minimum amount of compost for all new lawn installations, the city increases the water retention of its soils and reduces the city's water demand.… Read More

Leander, Texas – Compost Amended Soil

On March 15th, 2007, the City of Leander, Texas passed and approved the Water Conservation Ordinance No. 07-018-00. Drought prone climate conditions and sharing water rights to/supply from the Colorado River with regional states warranted expanded water conservation and environmental landscaping policies; most notably, a minimum required percentage of organic content in landscaping activities.… Read More

Washington’s “Soils for Salmon” – Compost Amended Soil

A nonprofit initiative, Soils for Salmon, came to transform state-level stormwater policy in the early 2000s. By advocating for the incorporation of compost use in land development practices, the program has helped Washington state to realize the many benefits of compost amended soil. The program specifically targets/drives landscapers, builders, developers, and citizens to use low impact development practices, which reduce stormwater runoff and pollution, while limiting water usage demands. … Read More
