Wenzel, Inc.

The Charles River, Bogastow Brook, and the town's wetlands put many Millis lots within the 100-foot buffer or the river's 200-foot Riverfront Area under the Wetlands Protection Act, so the Millis Conservation Commission reviews grading, clearing, and hardscape near water — typically through a Request for Determination or Notice of Intent. Floodplain lots near the Charles may carry added rules. Retaining walls over four feet generally require a building permit and engineered plans, and projects altering runoff toward the river can trigger stormwater review. Confirm whether your lot sits in the Riverfront Area before designing near the water.

Millis landscaping prices sit in the moderate MetroWest band — below Boston-metro core rates but above the rural Worcester towns. Routine mowing runs about $50–$90 per visit, spring cleanups $300–$700, and fall cleanups $350–$850. Mulch is roughly $80–$130 per yard installed, and irrigation for a typical lot runs $4,500–$9,000. A paver or bluestone patio commonly lands at $9,000–$18,000, while a full design-build with grading, plantings, stonework, and lighting ranges from about $24,000 into six figures depending on lot size and access.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential landscaping work; ask for the registration number and check it before paying a deposit.
