Ballona Wetlands Ecological Preserve Waterflow and Dewatering Impact (32 Slides)
When it rains, Los Angeles sends billions of gallons of 'free liquid gold' down the drain
During one of this winter’s frequent storms, sheets of rainwater spilled from roofs, washed across sidewalks and down gutters into a sprawling network of underground storm drains that empty into the Los Angeles River channel. (Same goes for Ballona Flood Control Channel. Billions of gallons of rainwaterflow into the Pacific Ocean at Santa Monica Bay.)
You can reduce your water bill by capturing "free" rainwater.

BIOSWALES: WHAT ARE THEY?
Thanks to these natural runoff filtration structures, we don't have to choose between great landscape aesthetics and eco-friendly design.

Bioswales are a unique green solution to the problem of contaminants in stormwater runoff. Bioswales slow down and collect polluted stormwater runoff and then filter it prior to returning it into the water cycle. They accomplish this filtration with the help of two natural processes: filtering water by passing it slowly through porous material, along with phytoremediation, where plants remove contaminants. Bioswales can contain sand, compost, and rock trenches along with native species of plants, which are adapted to local conditions. The inclusion of local plants is also important on an aesthetic and educational level: these plants blend in with the local environment and can serve as a tool to educate the public on issues of native biodiversity. Bioswales are a small but necessary remedy to the unmitigated proliferation of paved surfaces in our car- centric world. Parking lots especially create massive concrete plains incapable of absorbing or filtering stormwater.

WHAT DO BIOSWALES FILTER?
Metallic compounds such as mercury and lead

The underground greenhouse, has no expensive clear sides (plastic or glass), a cheap plastic sheet roof to let in more light than glass, and heat loss through walls to the air, which can be colder than the ground (57 degrees Farenheit or so), so it will be cheaper to build and run.
Of course, it's a lot of digging, and the left over dirt must go somewhere. Hint: Save the top 10 inches of top soil when starting to dig for use in the greenhouse.

Our web site adds pages to document many ways of capturing storm water, both private and public. Grassroots Coalition has been showcasing public sewer and storm water cleaning since 2005, when a Japanese Designer presented on her grand success with the first public park sewer plain earth filtering. This method is making headway here in the USA with a New York City first, called Sponge park. Details at the URL below.
An article reference from Yes Magazine. Why is it included on this web site? The direction of short term change towards long term goals of Los Angeles Area water independence from imported water is half way told. It's just one journalist's research of many residential advocates in the LA neighborhood.

Protecting Clean Potable Water is the Central Issue.
At some point in the not too distant future we will need to choose between FOSSIL FUELS and WATER for farming, drinking, cooking, bathing, flushing the toilet, putting out forest fires, etc. Who knows how many open, unlined pits there are or the amount of illegal dumping or pumping is being done?
