Elk Grove uses Pervious Concrete in a Round-About Way

Elk Grove uses Pervious Concrete in a Round-About Way

To improve traffic flow at a busy intersection in Elk Grove, the City turned a four way intersection into a round-about. But it's not just any round-about, the new intersection also included features to enhance pedestrian safety and pleasure. Among those features is the new pervious concrete pedestrian and bike path that encircles the round-about. See more by watching the virtual fly-over video.

Arroyo Mocho Trail Trys Out Some Pervious Concrete

Arroyo Mocho Trail Trys Out Some Pervious Concrete

The City of Pleasanton is trying to solve two issues they are having along their Arroyo Mocho Trail, flooding and maintenance costs. The project represents a testing site for the city to study and compare surface performance and maintenance costs of asphalt, decomposed granite and pervious concrete. Pervious concrete was specifically installed in an area that is prone to flooding. We, at BAPC, are pretty confident they will find similar results that other cities have when it comes to the high performance and low maintenance costs of pervious concrete.

Santa Cruz loves Pervious Concrete

....for park multi-use trails!!

Revisited the trail in March 2015.

Revisited the trail in March 2015.

While we know pervious concrete is a great multi-use trail material, the City of Santa Cruz spent years seeking the perfect trail material before they settled on pervious concrete for the Arana Gulch multi-use trail project. They needed something that was safe and non-slip in all weather conditions, accessible for wheelchairs in all weather, protected water quality, was permeable, low maintenance, and looks the part- clearly pervious concrete! 

The City agreed that pervious concrete met all their needs and then some. Below is the list of features they considered in selecting pervious concrete:

  • Durable;  does not rut, ravel or crack easily 
  • Strong; stays firm, level and safe
  • Long life expectancy
  • Low glare
  • Integral color of native earth
  • Low maintenance
  • Good for wheelchairs, strollers etc.
  • Less inviting for skateboards and fast traffic
  • Accommodates light maintenance vehicles
  • Rustic appearance
  • Porous 
  • Cost effective

We don’t need to quote them further, read their original blog post for more details. Great work, Santa Cruz!! Even more great they hired BAPC to install it. Above you can see a photo of the Broadway Brommer Arana Gulch path that we installed.  If you use the Arana Gulch Broadway Brommer Multi-Use path, send us your photos, and we would love to post them!

Pervious Concrete and Maintenance - Your Questions Answered!

 

Recently, maintaining pervious concrete has come up several times in a week, prompting this blog post. The good news is that this conversation is happening. The bad news is that some people who are not on board with pervious are using an ill-informed maintenance opinion to shape their judgement. We here at Bay Area Pervious Concrete would like to clear up a few of the misconceptions around maintenance.

Firstly, we have found the relevance of maintenance is tied directly to the porosity of the slab itself. A healthy infiltration rate for a slab of pervious concrete is 250-1000 inches per square foot per hour. That ensures that even if the slab was 99% clogged, and the 5 year storm event was 3 inches in 24 hours (as we have here in the Bay Area), that slab would easily be able to absorb that entire storm. So at 99% clogged, the slab would take in 2.5 inches - 10 inches of stormwater per hour per square foot!

Secondly, here are three helpful resources to help with installing a good slab, maintaining it and the fixing a worst case scenario:
1) In order to make sure you get your healthy infiltration rates, an experienced and qualified contractor is required. We have performance based specs that you may review, so that you can be sure to get a good contractor and get a great pervious concrete installation! We also have a BAPC PolishedTM Pervious Spec that we will send at your request.

2) Regular maintenance that can be done, if there is a budget and a desire for a plan. We have put together a maintenance manual that we give to clients at their request when we finish work for them. This gives an idea what you can anticipate, allows one to set up a maintenance schedule, and has resources to call if clogging does occur.

3) Pervious concrete can recover porosity after clogging over years as shown from a research paper from Florida that came out a few years ago. The paper shows several slabs of unmaintained pervious ranging in age from 6 to 20 years old that were able to recover significant infiltration after a pressure washing, vacuuming or a combination of both - after YEARS of neglect. So, no maintenance, no problem!

Commodore Park in San Jose is now ready for a Frisbee!

San Jose’s newest park features a colored pervious concrete path going around the park! And it is finally open! Santa Clara Valley Urban Runoff Pollution Prevention Program honored the City of San José with an award for Commodore Park’s Site Design and Low Impact Development for Storm Water Pollution. The award recognizes the park's low-impact development features that are helping to protect water quality by filtering stormwater through plants and soil, while allowing stormwater to infiltrate into the ground to help replenish groundwater. 

Time to load up the family, grab the frisbee and explore this great new space. It has children’s playground equipment, adult’s exercise equipment, picnic areas and a grassy expanse, all accessed by ADA friendly pervious concrete. It is a lovely space to spend the day.


If you head out there, please send us photos of you enjoying the park! We will post them here! :)

 

White Hill Middle School Gets a Brand New Courtyard

White Hill Middle School up in Marin County is the first school to put in polished pervious concrete! WRNS Studio designed it in the main courtyard area between classrooms as well the shaded amphitheater style steps, shown below.

The finishing touches were just getting completed as teachers were prepping classrooms in anticipation of classes starting. It was very exciting!


We were able to get this fantastic design installed with the help of a dedicated team of design professionals. Joel Williams and Pauline Souza from WRNS Studios were invaluable as design advocates for pervious concrete from the beginning of the project. Mike Hastings, from Sherwood Engineering, was the civil on the project, and his collaboration and cooperation on the technical aspects enabled us keep momentum going. We look forward to working with both of these firms in the future, for more pervious concrete projects!!

And here is our favorite shot - a close up of the nice tidy finish, and the subtle color variations in the polished finish the school administrators were looking for.


Photos of the Finished Valley Oak Co-Housing Project

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! :)

 

UC Berkeley's newest path is pervious

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.

Pervious Patio at the Hyatt Regency SFO

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.
