Tamien Park - Community Driven Design with Stormwater in Mind

Tamien Park - Community Driven Design with Stormwater in Mind

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!

Affordable Housing with Pervious Concrete is a Win for Developers and Tenants

Affordable Housing with Pervious Concrete is a Win for Developers and Tenants

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.

Pervious Concrete Meets Regulation, Lowers Project Costs, and Generates Revenue

Pervious Concrete Meets Regulation, Lowers Project Costs, and Generates Revenue

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.

Stormwater Sleuthing - Episode 3 - El Camino Park, Palo Alto

Stormwater Sleuthing - Episode 3 - El Camino Park, Palo Alto

El Niño brought us a gift this winter, some much needed rain! The most recent storm allowed us to finally bring you another in our Stormwater Sleuthing Video series. This episode features a real-life demonstration of the performance of pervious concrete at our recently completed project at El Camino Park in Palo Alto, as compared to traditional asphalt and concrete.

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.

Residential Driveways Using Pervious Concrete - Mother Nature Approved!

Residential Driveways Using Pervious Concrete - Mother Nature Approved!

Pervious concrete helped this residential development meet the Provision C.3 in the Municipal Regional Permit - which require site designs for new developments and redevelopments to minimize the area of new roofs and impervious paving. Concord, among many other bay area cities, have restrictions on how impervious a development can be. Pervious concrete when incorporated into the stormwater control plan allows you to combine your hardscape with your stormwater management system - reducing costs and environmental impact, while increasing development space. Win-Win-Win!

The GREENEST mix - Pervious Concrete can get GREENER

The Greenest Mix we have ever devised!
Guest post, written by David Liguori

I wanted to give you a quick update on one of the more significant developments we’ve achieved lately.
 
In our continuing quest to further improve the performance of pervious concrete we have developed an “ultra-green” mix design for which we have recently received test data. The mix contains only 245 lbs. of cement, vs. 5-600 lbs. for regular concrete, and 245 lbs. of  supplementary cementitious materials (scm). The scm consists of a combination of fly ash and slag, both industrial waste products.
 
We used this mix this past January on a 2,000 ft. long (by 10’ wide) driveway in Palo Alto(photo above) and 3 months ago on a 5,000 sqft. driveway in Los Altos Hills (photo below). They are both performing quite impressively. Absolutely no surface raveling, all of which typically takes place in the first month or two if it’s going to happen, water infiltration rates of 700-1,200” per hour and compressive strengths above 3,000 psi.
 
As I am sure you know the addition of the scm’s slows down the rate of early strength gains but ultimately results in higher overall strength. In the case of the ultra-green mix our 28 day numbers are in the  2,600 – 2,900 psi range and to our delight the recent 90 day test came in at an outstanding 3,520psi. These type of results and data continue to increase our confidence in pervious concrete as viable long term stormwater management solution.
