File:SWTT Struct Pan High Perm Final crop.png|thumb|500 px|'''A Stormwater tree trench with structural concrete panels and soil cells.''' A structural concrete panel configuration is an alternative to modular soil support systems that uses a “bridge deck” over bioretention/growing media that extends into the pedestrian clearway, and is supported on each side by concrete supports and compacted granular material. The benefits to this configuration is increased infiltration due to the extra provided modular support, therefore no compaction of the underlying drainage material is required. <span style="color:red">'''''Note:''' The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>
File:SWTT Struct Pan High Perm Final crop.png|thumb|500 px|'''A Stormwater tree trench with structural concrete panels and soil cells.''' A structural concrete panel configuration features reinforced concrete panels supported by concrete footings and rows of modular soil support structures and extend into the pedestrian clearway. Modular soil support structure rows are installed on layers of compacted granular material and filled with growing medium. Benefits of this configuration are improved adaptability around utilities, improved ease of utility access and repair tasks, and greater soil volume achieved per unit area compared to modular soil support and structural soil medium filled trench configurations. Preventing compaction of underlying native subsoil in the area between the aggregate base layer rows provides greater opportunity for drainage via infiltration. <span style="color:red">'''''Note:''' The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>
