Stormwater BMP Maintenance Agreements: Why They’re Required and How We Help

Written By Joe Gilmartin

Stormwater management isn’t just about preventing puddles or protecting landscaping—it’s about protecting the environment, public health, and property infrastructure. In Massachusetts, stormwater BMP (Best Management Practice) maintenance agreements are a legal requirement for many residential, commercial, and industrial developments. If you're a property owner, builder, or HOA, ignoring this obligation can lead to serious compliance issues, environmental damage, and costly fines.

At Amex Construction LLC, we specialize in stormwater control—and we go beyond installation. We help clients across Southeastern Massachusetts, Cape Cod, and the South Shore stay compliant with EPA, NPDES, and MassDEP regulations through professional BMP inspection, maintenance, and documentation services.

What Are Stormwater BMPs?

BMPs (Best Management Practices) are structural or engineered systems designed to:

  • Control runoff volume and rate

  • Filter pollutants

  • Prevent erosion

  • Recharge groundwater

Common examples include:

  • Catch basins

  • Rain gardens

  • Infiltration trenches

  • Detention and retention basins

  • Swales, storm drains, and filter strips

Most municipalities and conservation commissions require long-term maintenance of these systems—and proof that it’s being done.

Why Maintenance Agreements Are Required

Municipalities across Massachusetts enforce Stormwater Controls & BMP maintenance through:

  • Stormwater bylaws

  • Conservation Commission Orders of Conditions

  • NPDES permits

  • MassDEP Wetlands Protection Act standards

If you're issued a permit or certificate of compliance for a development, you are typically required to:

  • Maintain BMPs in perpetuity

  • Conduct and document regular inspections

  • Submit reports to town officials or third-party reviewers

Failure to comply can result in:

  • Fines or stop-work orders

  • Environmental damage

  • Revoked occupancy permits

  • Costly retrofits

💬 “Stormwater systems are critical infrastructure—not just landscaping. We help you keep them working and compliant.” – Joe Gilmartin, Amex Construction LLC
