LID Facility Calculator Tutorial

To size rain gardens and stormwater planters, watch this tutorial to learn how to enter the right information in the user inputs of the open source Excel models.


 

Vegetated Infiltration Facilities Siting Tutorial

Siting for safe infiltration can be tricky. Watch this video to find out where you should and shouldn't put an infiltration rain garden, stormwater planter, or vegetated filter strip.

Porous Pavement Video 1: Modeling Rainfall

Using an open source Excel worksheet, learn the steps to hydrologically model porous pavement when it is installed to only manage rainfall, not runoff from other areas (aka hydrologically isolated). You may be surprised to see that soils with very low infiltration rates are still appropriate for porous pavement.

Caveats: 1. Determining cross-section for vehicular or pedestrian loads should be performed by a geotechnical engineer and is not covered in this training. 2. The modeling approach is sound for any porous pavement; however, the Excel sheet is for a Type IA storm distribution only.


 

Porous Pavement Video 2: Modeling for Detention (Flood Storm Attenuation)

Using an open source Excel worksheet and building on the knowledge in video 1, this alternate open-source Excel worksheet will show you how porous pavement can replace detention, at least for the expanse of area covered by porous pavement. This is also for porous pavement when it is installed to only manage rainfall, not runoff from other areas (aka hydrologically isolated)

Caveats: 1. Determining cross-section for vehicular or pedestrian loads should be performed by a geotechnical engineer and is not covered in this training. 2. The modeling approach is sound for any porous pavement; however, the Excel sheet is for a Type IA storm distribution only.


 

Porous Pavement Video 3: Modeling Rainfall & Runoff

Using an open source Excel worksheet and building on the knowledge in video 1, this open-source Excel worksheet will show you how porous pavement can be used to infiltrate the rainfall it receives as well as runoff from other areas (i.e NOT hydrologically isolated).

Caveats: 1. Determining cross-section for vehicular or pedestrian loads should be performed by a geotechnical engineer and is not covered in this training. 2. The modeling approach is sound for any porous pavement; however, the Excel sheet is for a Type IA storm distribution only.
