*'''Deepwater zone''' – From 1.5 to 6 feet deep. Includes the outlet micropool and the deepwater channels through the wetland facility. This zone supports little emergent wetland vegetation but may support submerged or floating vegetation. It is consistent with the Cowardin Wetland Classification of palustrine aquatic beds. | *'''Deepwater zone''' – From 1.5 to 6 feet deep.

Stormwater wetlands are constructed with varying amounts of the following three components:
The amount of each of the components named above depends on the desired type of stormwater wetland (e.g., shallow wetland). Figure 12.WETL.1 shows the three major types of stormwater wetlands presented in this Manual.
