How To Select a BMP
The BMPs have been
categorized into functional areas to facilitate the integration of the
approach into appropriate land uses and into the appropriate location on
each site.
BMP Selection Flow Chart (PDF)
There are seven (7)
categories that either describe a strategy or approach for the
technology. The categories were selected and identified because of
industry interest and because of the understanding of the technology.
This approach will allow for reviewers to evaluate modifications and
variations within the context of the overall LID strategy or family of
technologies. Listed below is a brief description of the areas. (This
website contains one design example: Bioretention.)
§
Bioretention Systems:
These systems include a high filtration rate engineered soil and plants
that process and filter pollutants. The systems can be designed as
conveyance, detention, or retention systems.
§
Filtering Technologies:
Proprietary and non-proprietary media used to trap or treat pollution by
flow control.
§
Permeable Pavements:
Pavement systems that include a permeable surface capable of supporting
traffic loadings. These systems include a gravel reservoir for storage
of runoff through exfiltration or for detention storage.
§
Site Design Strategies:
Site design strategies that minimize the hydrologic and hydraulic change
on the land through clustering, site fingerprinting, and
flow path disconnection.
§
Soil Amendments:
Addition of organic and other amendments to soil and mechanical methods
that help restore the infiltration capacity of the soil.
§
Vegetative Systems:
Planting of
vegetation to filter or absorb rainfall and runoff.
§
Water Conservation/Reuse:
The capture and storage of runoff for secondary uses such as irrigation,
cooling, and other potable and non-potable uses.
