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.
It's April, so it's the perfect time for some spring cleaning! Time to clean out those dusty pervious concrete specifications and design details you have laying around, and replace them with something new and fresh. We have released new updates on all the favorites!

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
Affordable housing doesn't have to mean your project is stuck with old conventional materials to save cost. The Met Apartment buildings in San Jose, CA are part of a newly constructed community development project by Charities Housing that will be adding 100 affordable housing units to the city. Built to the City's Green Building Guidelines the project showcases a variety of sustainability features. One of these features is the pervious concrete drive lane that will serve as the entrance into the buildings' shared parking garage. This drive lane is anticipated to be a high volume area for residents coming and going from the complex.Read More
During the last winter rain storm of 2016 David went to visit some of our work at the Hyatt Regency in Burlingame, CA. It was really rainy the day he visited, so in this episode you can really see the difference in how stormwater is handled by an impervious pavement versus a pervious pavement.Read More
There is a new pervious parking lot in Richmond, CA. Located at the new Harbourview Apartments this parking lot is 100% pervious concrete. Parking lots are the perfect application for pervious concrete. They epitomize the principal of the Large Area Thin Infiltration Systems (LATIS). Converting the pavement into a passive storm water detention system, that meets Provision C.3 Municipal regulations, without giving up valuable land to rain gardens, bioswales or detention ponds. By utilizing pervious concrete for the entire parking lot, this project was able to build more rentable units and achieve the most cost-effective solution, all while meeting Provision C.3 regulations.Read More
The Peninsula Open Space Trust (POST) is a non-profit organization that protects and cares for open space, farms and parkland in and around Silicon Valley. It was very important that their office's renovation represented their commitment to their environmental mission. Working with their designer Steve Kikuchi, from Kikuchi + Kankel Design Group, they decided to use pervious concrete for their new parking lot.
Integral color and decorative accent borders of conventional concrete were utilized in order for the parking lot to complement the building's design. So this does not look like any other parking lot you've ever seen.
The last time that the category of El Niño was considered Very Stong was the winter of 1997-1998, where many California communities suffered from mudslides and flooding. This year's El Niño is showing signs that it could be even stronger. There is a strong chance that the Bay Area could see as much as twice the annual precipitation, maybe above 40 inches of rain. This could greatly impact the state by damaging homes, disrupting transportation systems, schools, and businesses - potentially costing state residents billions of dollars. Many cities are preparing for the additional rainfall by cleaning out their waterways and storm systems. California officials are warning people to prepare for potential flooding conditions. You may be asking, "What can I do to reduce the risk of flooding for my home or business?"
One thing you can do is by replacing sidewalks, driveways, parking lots, patios, and roads with pervious concrete. Luckily, installing pervious concrete is one type of El Niño preparation you may be able to receive a rebate for. Saving you money upfront and in the long run!
Over the past few weeks we have seen the internet explode with interest over the recently announced Topmix Permeable concrete from Tarmac Lafarge in the UK. People are marveling over concrete that allows water to not only go through it, and back into the ground, but at an incredible rate. The video we featured on our last blog post is impressive and demonstrated just how fast. We were excited to see so much interest in pervious concrete by so many different people. However, we did notice some discrepancies in the way that pervious concrete was discussed in some of the media outlets, and we wanted to take some time to clarify a couple things.
Some of the media outlets portrayed pervious concrete as a new product that was not available in the United States - which is false. Pervious concrete has been used for stormwater management throughout the US for over 40 years. What's different, or innovative, about Tarmac's Topmix Permeable concrete is it boasts a whopping 35% air void space, which is why it infiltrates at such a high rate. Tarmac representatives have stated in interviews that the product has some limitations on where, and when, it should be used. They are not recommending Topmix Permeable for high-traffic areas, in places where vehicles make lots of tight turns, or in places with freeze-thaw cycles, as it will eventually start breaking up the surface layer. Some media corespondents have portrayed that all pervious concrete had these limitations - which is also false. While Topmix Permeable may have these limitations, more traditional pervious concrete does not share the same limitations. In the US, mix designs have evolved and have already solved the issues of heavy traffic, weight loads, turning vehicle traffic, and freeze/thaw cycles.
Through trial and error the pervious concrete industry has discovered that 20% air void space provides the proper balance between strength, durability, and high infiltration rates. The additional bonds provided by only having 20% air voids, allows for a stronger, longer-lasting material, with just as much infiltration capacity to mitigate all of a site's stormwater.
The internet has been calling this pervious concrete "Super permeable" and Magical." If you agree, you don't have to travel to the UK to see it or have it! Bay Area Pervious Concrete has been installing super pervious concrete management systems for nearly a decade. This viral video, from the UK firm Lafarge Tarmac, is a great representative of how fast pervious concrete can infiltrate water, but how does pervious concrete handle longer water events - like heavy rain storms? A real life test of pervious concrete. In our Stormwater Sleuthing video David compares two driveways after at least 12 hours of steady rainfall.Read More
When most people think of road pavement, they think of asphalt. The new East Dunne Ave housing development in Morgan Hill, CA decided to do something different. They had Bay Area Pervious Concrete install pervious concrete from curb to curb for the new Seville Drive. Pervious concrete works great for roadways. Pervious concrete roadways have a lifespan of 30-50 years before it may need to be replaced. They are largely maintenance free for their entire lifespan. The extra benefit of pervious concrete is that it is a stormwater management system that doubles as a pavement.
Unlike pervious concrete roads, asphalt roadways have short lifespans, and require regular maintenance. Asphalt roads must be replaced, or resealed, every 10-15 years. This increases the maintenance necessary and inconvenience for residents. Typical asphalt roads also do not provide any stormwater management services. In fact they can actually contribute to poor stormwater management by concentrating pollutants that collect on the surface and rapidly shedding them into local waterways.

Parking stalls never looked so good! Here you can see, courtesy of Google maps, the top down look at parking stalls for this large apartment complex in Soquel, California. Below, you can see up close, pervious parking stalls with marking paint. While we don’t encourage AC pavement draining onto adjacent pervious concrete as a design concept, this went in well, and will be in service for a long time. Find more photos below!
We are excited to announce that we, at Bay Area Pervious Concrete, hold an Evolution Architectural Pervious Concrete Certificate of Endorsement from Evolution Paving to install their Architectural Fine Pervious Concrete sidewalk mix! We have worked with Evolution paving on a project in Sonoma, more photos here, installing the fine sidewalk mix, and we have it down - pun intended.
Please contact us for pricing and references so that we can install for you soon!
As the landscaping grows in, and the people move in, the pervious concrete hardscapes just get better looking! Check out the below photos for a more updated view of Evolution Paving’s Architectural Fine Pervious Concrete that we placed at the Valley Oaks Co-Housing project in Sonoma.
Tell us what you think! Do these look like livable hardscapes to you? Honestly, I just want to pet that puppy! :)
The Simons Institute for the Theory of Computing has a new home in the Melvin Calvin Laboratory building on UC Berkeley’s campus. And skirting the southwest edge is a new polished pervious concrete path! The next time you find yourself on campus, I hope you bring some water and pour some out on their new pervious path!
This is where the path is adjacent to Optometry Lane.
The Hyatt wanted a new look and feel for two areas on either side of a walkway that connected the north entrance and the parking garage. They wanted to rip out the existing plants and replace it with a usable patio space. They also wanted pervious concrete - so they called us!
After we installed the Polished Pervious® concrete, we scored it, completing the look. The Hyatt put out this sleek and modern furniture, turning this previously unusable corner into a nice place to take a break! Below is the larger area, to the east of the pathway.
