Design Specification No 11: Wet Swale
Wet swales can provide runoff filtering and treatment within the conveyance system and are a cross between a wetland and a swale.

Bioretention creates a good environment for runoff reduction, filtration, biological uptake, and microbial activity, and provides high pollutant removal; bioretention can become an attractive landscaping feature with high amenity value and community acceptance.
Infiltration practices use temporary surface or underground storage to allow incoming stormwater runoff to exfiltrate into underlying soils, allowing for a very high runoff volume reduction capability.
The karst terrain in the Bay watershed is distinct from some other regions in that the bedrock is very ancient and, in many areas, is deeply buried by residual soils.

Webcast explaining the challenges for stormwater in a ‘dissolving landscape’ such as karst terrain.
Many designers feel the rules for disconnection are frequently abused and are not very effective for compacted soils.
Karst is a dynamic landscape characterized by sinkholes, springs, and caves. Karst terrain complicates the land development process and requires a unique approach to stormwater design.
The promise of permeable pavement has always been powerful, however, seldom realized.
