<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>Image here</td></tr>
<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>Image here</td></tr>
