| <caption><strong>Types of bioretention cell</strong></caption>
| |
| <tr class ='success'><th>Form</th><th>Characteristics</th><th>Examples</th></tr>
| |
| <tr><td>Infiltrating cells</td><td>Used in developments with large landscaping areas, parks, parking lot islands, or any areas without tight space constraints. They have side slopes ≥2:1. Often, they receive sheet flow, but in some cases they are surrounded by curbs and will have inlets. The distinction between these options will determine the recommended types of pre-treatment. </td><td>

| |
| <tr><td>[[Rain gardens]]</td><td>Often found on residential sites or on land managed by community organisations . This simple variation may be constructed by the property owner and usually excludes the storage layer. </td><td>See main article on rain gardens</td></tr>
| |
| <tr><td>Bioretention planters (stormwater planters)</td><td>Typically used in ultra-urban areas adjacent to buildings and in plazas. They appear similar to traditional landscaped beds, but differ by receiving runoff from nearby surfaces.</td><td>Image here</td></tr>
| |
| <tr><td>Extended tree pits (parallel bioretention)</td><td>Located within the right-of-way, occupying the space between sidewalk and street. The inlets can be positioned on either or both sides, and are designed to prevent the system from filling beyond a fixed capacity. When ponding occurs, stormwater bypasses the inlets, making this a 'parallel' system rather than a flow-though or online design. </td><td><gallery mode="packed" widths=300px heights=300px>

| |
| <tr><td>Curb extensions (bump outs)</td><td>Installed in road-right-of-way, these function as a stormwater facility and a traffic calming measure. Inlets are integrated into the raised concrete curb and receive flow from the street side.</td><td>Image here</td></tr>
