Bioenvironmental Engineering
  • Concerned with maintaining the quality of our environment
  • Apply physical, biological, and chemical sciences to design solutions for environmental issues
stormwater management
Stormwater Management

Stormwater Runoff

Result of Development

  • Impervious Surface Additions
  • Soil Compaction
  • Removal of Trees and Vegetation

Infiltration, Interception, and Evapotranspiration Reduced

Overland Flow Increased

stormwater management5
Stormwater Management

Stormwater identified as a leading source of pollution for all waterbody types in the U.S.

stormwater management6
Stormwater Management
  • Three Basic Levels of Management
    • Regional/Watershed Scale
    • Community or Neighborhood Scale
    • Site/Block Scale

Low-Impact Development

LID is an approach to land development (or re-development) that works with nature to manage stormwater as close to its source as possible. LID employs principles such as preserving and recreating natural landscape features; and minimizing effective imperviousness to create functional and appealing site drainage that treats stormwater as a resource rather than a waste product.
