* Step 7: Sum total depth of bioretention components, and compare to available space (i.e. depth) between the proposed surface grade and the seasonally high water table or top of bedrock elevations in the practice location.  

* Step 7: Sum total depth of bioretention components, and compare to available space (i.e. depth) between the proposed surface grade and the seasonally high water table or top of bedrock elevations in the practice location.  

* Step 8: Adjust component depths to maintain a separation of 1.0 metre between base of the practice and seasonally high water table or top of bedrock elevation, or a lesser or greater value based on groundwater mounding analysis.  See below and [[Groundwater]] for more information.<br>

For practices without an underdrain in locations constrained in the vertical dimension, consider decreasing filter media depth (and plant types) or catchment area.<br>

For practices without an underdrain in locations constrained in the vertical dimension, consider decreasing filter media depth (and plant types) and/or catchment area.<br>

For practices with an underdrain in locations constrained in the vertical dimension, consider decreasing filter media depth (and plant types), ponding depth or catchment area.
