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.
Stormwater wetland design must be tailored to site characteristics; however, some general RECOMMENDED design criteria for shallow wetland, ED shallow wetland, and pond/wetland design are presented in Table 12.WETL.1.
