The C.3 workbook recommends a combination of techniques that can add significant cost and complexity to projects. A pervious concrete water management system designed and installed by Bay Area Pervious Concrete can mitigate 100% of your total project runoff at a much lower cost.

Cost Benefits of Pervious Concrete:

• No drainage infrastructure or curbing necessary
• No gardens, plants or special soils needed
• Utilize existing parking or hardscape area
• Maximizing value of available land
• Ability to capture 100% of site storm water runoff on site

Pervious concrete is an ideal solution for projects where there are driveways, parking lots, court yards and sidewalks on site as it allows you to fully comply with and even exceed performance mandates of C.3 LID regulations. By using pervious concrete, it is possible to capture 100% of annual storm events, including runoff from roofs and adjacent impervious surface, even in Type D soils or heavy clay. Pervious concrete allows for driving or parking on top of the stormwater detention pond, as seen in the images on the right. Let us show you how we do it!
