Shape the Ground Before Building Above It

Small elevation changes control large volumes of stormwater. A shallow depression can keep grass wet for days, while an overly steep bank sends mulch onto pavement during summer rain. Grading creates continuous, subtle movement without making the yard appear engineered. The final outlet matters as much as slope because water cannot simply be shifted onto another property or problem zone. Developed Somerville-area lots may contain compacted fill, buried stone, construction remnants, and inconsistent topsoil depth. Excavation can reveal conditions that were invisible from above. Pavement needs firm support, while beds and lawns need soil roots can enter. Applying the same compaction to every zone can leave either hardscape unstable or growing areas inhospitable. Work near a house requires controlled elevations. Soil and paving should maintain suitable clearance below siding and openings, and runoff should move away from the foundation. Basement entries, window wells, steps, downspouts, fences, walks, and neighboring yards limit available change. Where no safe surface route exists, drainage structures may be needed instead of grading alone. Disturbed ground needs prompt stabilization. Fine grading creates a smooth profile, but seed, sod, mulch, planting, or erosion-control materials protect it from the next storm. The right finish depends on slope, season, and intended use. Equipment access also deserves advance planning so gates, pavement, roots, and landscape features are not damaged while material is moved.
