Bay Area Pervious Concrete strives to provide designers and engineers with resources to make their stormwater & pervious concrete designs smarter, easier, and more cost effective. Our Technical Services division has out done themselves with their latest addition to our Resource library providing something you can't find anywhere else - Base Design Tables.
Want to know how much base rock you need under your pervious concrete pavement? We've done all the calculations for you! Designed with low infiltration soils, like Class C & D, in mind these design tables allow you to quickly size the infiltration bed underneath your pervious concrete. Tables feature calculations for infiltration rates as low as 0.025 inches per hour! Read for more details.Read More
Back in 2013 Bay Area Pervious Concrete was hired to install some BAPC Polished Pervious Concrete™ on the newly expanded campus of White Hill Middle School in Fairfax, CA. The project's site designs were done by our friends at Sherwood Engineers. Recently, a group of Sherwood Engineers project managers took a tour of the school to review how the site improvements fared after five years of use. They were kind enough to share some photos with us.
Our friend was happy to report that the pervious concrete still looked great and was performing well. The school appeared to be very happy with the site improvements, and it showed! The pervious concrete had been maintained, kept clean, and looked as good as the day we polished it.
Interested to learn how pervious concrete pavement systems are considerably more effective, and versatile, than other stormwater management BMPs?

Over the several years BAPC's David Liguori has worked with Caltrans to update their pervious concrete design guidelines and specifications. Recently, he and the California Nevada Cement Association were asked by Caltrans District 4 to provide a pervious concrete workshop for their material, pavement, stormwater, and highway engineers.
The three hour workshop provided 28 Caltrans engineers with the latest developments in pervious concrete system design, specifications, and best management practices. Afterwards attendees were bursting with ideas and projects where pervious concrete would help solve their stormwater design issues. They expressed how grateful they were that our presentation was technical, detail-oriented and highly educational, not just a fluffy sales-pitch.Read More
There has been some confusion as to what is the best base material to use for pervious concrete. Watch this video to see why you should specify open-graded crushed rock instead of "Class II Permeable Aggregate" as the base for pervious concrete sections.Read More
The second in our series of green infrastructure tours. This time Sonja O'Claire joined the ASCE SF Chapter's Sustainability Committee on a tour of the California Academy of Sciences ("The Academy"). Known as the "greenest musuem in the world," The Academy is an exhibit in-and-of itself for all things related to sustainable design. Tour attendees went behind-the-scenes to learn about the unique design elements The Academy employs to lower its impact on its environment.Read More

Most of the time in Northern California we enjoy fairly mild weather and sunshine, but it's not always sunny in the Golden State. The San Francisco bay area is known for its fog. This can provide some unique installation conditions, especially when you are installing pervious concrete on the top of the highest peak of the Santa Cruz Mountains, Mount Umunhum.Read More
Tamien Park is the newest park in San Jose, one that the community has been waiting years for. Since 2009 residents have spent countless hours in city meetings to help bring this family-friendly park to their community. Designed to meet the needs of the family-oriented community the 3.5 acre park features a playground, picnic areas, basketball courts, multi-use fields, and eventually an exercise station, Tai Chi area, community stage area and jogging path. Along with all those amenities, Tamien park was also designed to manage all of its stormwater on site - 90% of the park's 3.5 acres are permeable!Read More

Wouldn't it be nice to make better use of all the rain we have received this winter, by restoring our groundwater and aquifers, rather then just sending it to the bay or ocean? On Thursday, March 23rd, you can learn how to utilize your stormwater as a resource, rather than it being a nuisance, using Best Management Practices like, pervious concrete and dry wells.
Our partners at the Resource Conservation District of Santa Cruz County are hosting a free half day stormwater workshop, in which Bay Area Pervious Concrete will be providing an educational presentation and site tour. BAPC will explain how to design with pervious concrete using LATIS (Large Area Thin Infiltration System) and the latest specifications, to maximize stormwater capture while reducing project cost, and how to maintain it. Afterwards attendees will be able to take a short tour of two different pervious concrete installations, allowing for a comparison examination in order to see how much the design and specifications affect the outcome and long term maintenance.
The workshop is free, but space is limited - Register Here.
