    Integrating electronic devices that enable workers to suspend pumping during extreme weather events, periods of impeded access, or unexpected hydrologic conditions.

Remedy Construction, Operation and Maintenance

  • Plantings
    Selecting native grasses, shrubs, trees and other deep-rooted plants that are resistant to drought or increased temperatures where vegetation is used for shading, erosion control or wind breaks or for treatment or local buffering in wetland or riparian settings.
  • Power from off-grid sources
    Constructing a permanent system or using portable equipment that provides power generated from onsite renewable resources, as a primary or redundant power supply that can operate independent of the utility grid when needed.
  • Utility line burial
    Relocating electricity and communication lines from overhead to underground positions, to prevent power outages during and often after extreme weather events.
  • Weather alerts
    Electronic systems that actively inform subscribers of extreme weather events or provide Internet postings on local/regional weather and related conditions.

Site Operations and Infrastructure

  • Alarm networks
    Integrating a series of sensors linked to electronic control devices that trigger shutdown of the system, or linked to audible/visual alarms that alert workers of the need to manually shut down the system, when specified operating or ambient parameters are exceeded.
  • Building envelope upgrades
    Replacing highly flammable materials with (or adding) fire- and mold/mildew-resistant insulating materials in a building, shed or housing envelope
  • Hazard alerts
    Using electronic systems that actively inform subscribers of extreme weather events or provide Internet postings on local/regional weather and related conditions.
  • Plantings
    Installing drought-resistant grasses, shrubs, trees and other deep-rooted plants to provide shading, prevent erosion, provide wind breaks and reduce fire risk.
  • Power from off-grid sources
    Constructing a permanent system or using portable equipment that provides power generated from onsite renewable resources, as a primary or redundant power supply that can operate independent of the utility grid when needed.
  • Remote access
    Integrating electronic devices that enable workers to suspend pumping or selected activities during extreme weather events, periods of impeded access, or unexpected hydrologic conditions.
  • Utility line burial
    Relocating electricity and communication lines from overhead to underground positions, to prevent power outages during and often after extreme weather events.
  • Weather alerts
    Electronic systems that actively inform subscribers of extreme weather events or provide Internet postings on local/regional weather and related conditions.

Upland Components of Contaminated Sediments

  • Retaining wall
    A structure (commonly of concrete, steel sheet piles or timber) built to support earth masses having a vertical or near-vertical slope and consequently hold back loose soil, rocks or debris.
