H 4421 Massachusetts House · 194th Legislature (2025-2026)

An Act establishing healthy soil performance guidelines

H 4421 requires Massachusetts' Department of Environmental Protection (DEP) to create regulations for soil performance after construction projects, directly affecting developers and construction companies. The regulations will cover soil depth, quality, carbon storage, stormwater runoff, water quality, fertilizer use, and compaction, with the DEP working alongside UMass Amherst Extension to align with existing soil science practices. Violations could result in fines up to $1,000 for repeat offenses, with an appeal process through administrative law. The bill also adds definitions for "functional turf" (e.g., lawns, parks) and "utility turf" (e.g., erosion-control grasses) to clarify applicable land uses.
