Managing Stormwater on Hospital & Healthcare Campuses

Hospitals and healthcare campuses in the Mid-Atlantic region – especially in Maryland, Washington, DC, Northern Virginia, and Delaware – face unique challenges when it comes to stormwater management. These critical facilities often span large impervious surfaces like rooftops, parking lots, and roadways, making them vulnerable to flooding, erosion, and runoff pollution. As stormwater regulations tighten and extreme weather events become more frequent, it’s essential for facility managers and property stakeholders to adopt proactive stormwater management strategies.

Why Stormwater Management Matters for Healthcare Campuses

Regulatory Compliance

• • Healthcare facilities are subject to federal, state, and municipal stormwater regulations, including the Clean Water Act (CWA) and National Pollutant Discharge Elimination System (NPDES) permits.
  • In Maryland, DC, Northern Virginia, and Delaware, stormwater compliance requirements are often enforced by local environmental agencies and stormwater utility programs.
  • Non-compliance can result in fines, inspections, or costly remediation work – making prevention far more cost-effective.

Infrastructure Protection

• • Heavy runoff can cause flooding that disrupts patient access, damages buildings, and overloads drainage systems.

Improper stormwater drainage can undermine pavement, cause sinkholes, or deteriorate facility foundations over time.

Environmental Responsibility

• • Runoff from hospital grounds can carry pollutants such as oils, heavy metals, and medical waste into local waterways.
  • Implementing green infrastructure and proper BMPs (Best Management Practices) helps protect regional ecosystems like the Chesapeake Bay and its tributaries.

Common Stormwater Management Challenges for Hospitals

• Large Impervious Surfaces: Parking decks, rooftops, and helipads create massive runoff volumes.
• Space Constraints: Urban campuses, especially in DC and Northern Virginia, have limited space for stormwater features.
• Critical Infrastructure: Downtime is not an option. Systems must function during emergencies and adverse weather events.
• Ongoing Construction: Expansions and retrofits must account for additional impervious surfaces and updated stormwater requirements.

Best Practices for Stormwater Management on Healthcare Campuses

1. Routine Stormwater Inspections & Maintenance

• Schedule regular inspections of stormwater basins, drains, and green infrastructure.
• Clear debris and sediment buildup to ensure proper flow and function.
• In Maryland and Delaware, maintenance logs are often required for MS4 (Municipal Separate Storm Sewer System) compliance.

2. Upgrade or Retrofit Aging Infrastructure

• Outdated detention or retention basins may no longer meet current volume or pollutant removal standards.
• Consider retrofitting with modern systems like Contech StormFilters, bioretention cells, or permeable pavement to improve performance and water quality.

3. Implement Green Infrastructure Solutions

• Rain gardens, green roofs, and bioswales help capture and infiltrate runoff onsite.
• These systems reduce strain on municipal storm drains and offer added benefits such as heat reduction and aesthetic appeal.

4. Plan for Emergency Stormwater Capacity

• Incorporate overflow design and backflow prevention to protect sensitive areas like ER entrances and power supply zones.
• Ensure generators, electrical rooms, and critical supply areas are protected from floodwaters.

Regional Stormwater Management Considerations

Maryland:

• Hospitals must follow Maryland Department of the Environment (MDE) guidelines for stormwater management under the 2007 Stormwater Management Act.
• Chesapeake Bay restoration goals further influence runoff reduction strategies across the state.

Washington, DC:

• Facilities must comply with DOEE (Department of Energy & Environment) stormwater management requirements.
• Green area ratio (GAR) requirements apply to new developments and renovations.

Northern Virginia:

• VDOT and local jurisdictions (Fairfax, Arlington, Alexandria, etc.) enforce strict erosion and sediment control plans.
• New construction and BMP retrofits must meet Virginia DEQ standards.

Delaware:

• The Delaware Sediment and Stormwater Program governs stormwater design, inspection, and maintenance.
• Facilities must submit maintenance agreements and perform regular reporting to stay compliant.
