StormWater / ADAC Version v4.1
ADAC
WSUDArea
Represents a Water Sensitive Urban Design (WSUD) area feature. Also often called a StormWater Quality Improvement Device (SQID). Use area features to represent constructed wetlands, bioretention basins, biofiltration beds, swales etc.

Attributes
Required and optional XML attributes
TreatmentMeasure
enum
Required
The treatment measure employed. Choose from a list relevant to complex area features.
Accepted Values
ValueDescription
BufferStrip
A buffer strip is a vegetated slope. Stormwater flows across a buffer strip. Treatment is provided by infiltration to the soil and by filtration of shallow flow through the vegetation.
Swale
A swale is a shallow trapezoidal channel lined with vegetation. Stormwater flows along a swale. Treatment is provided by infiltration to the soil and by filtration of shallow flow through the vegetation.
BioretentionSwale
Bioretention swales include a vegetated infiltration trench within the invert of a swale. Incorporating the infiltration trench enhances removal of both particles and nutrients.
SedimentationBasin
A sedimentation basin is a small pond, about 1m deep, designed to capture coarse to medium sediment from urban catchments. Treatment is provided primary through settling of suspended particles.
BioretentionBasin
A bioretention basin is a vegetated bed of filter material, such as sand and gravel. The basin is designed to capture stormwater runoff which then drains through the filter media. Pollutants are removed by filtration and by biological uptake of nutrients.
ConstructedWetland
Constructed wetland systems are shallow, vegetated water bodies the use enhanced sedimentation, fine filtration and biological uptake processes to remove pollutants from stormwater.
Function1
enum
Required
The first function of the WSUD area. At least one function must be supplied. Choose from a list relevant to complex area features.
Accepted Values
ValueDescription
