Water Water Everywhere, but NOT in CA? – Yes It is!:
CA Is Sitting On The Solution To Its Drought Problem
Terry Tamminen, CoExist, Fast Company, May 1, 2015, wrote
“About a decade ago, the blue-collar community of Sun Valley in Los Angeles County was faced with flooding that impacted homes and businesses during winter rains. The county had planned a $47 million storm sewer system to drain the floodwaters from streets and dump it in the Pacific Ocean via the Los Angeles River (itself now a mostly concrete flood management canal). Instead, clever community planners decided to invest those funds in underground cisterns that would capture the water for later use.
A dilapidated city park was remodeled with cisterns under the park, as were medians along broad boulevards that were themselves underwater during heavy rains. The result was a system, using ancient Roman technology, that captures 8,000 acre feet of water each year. That’s about twice what the entire city consumes, solving the flooding problem and creating a source of fresh water for thousands of residents. The investment also gave the city a new park with ball fields and picnic grounds and higher adjacent property values (see below).
But could something this simple be the solution for a thirsty state that is getting hotter, growing faster, and producing more food crops than ever before?
According to the National Weather Service, the average annual rainfall in Los Angeles for the past 100 years is about 14 inches, more than enough to serve the needs of the region and then some. From 2003 to 2012 CA had wet years of nearly 38 inches of rain and dry ones of less than 4 inches, but the average was still just under 14 inches, meaning there is no drought in the most populous region of the state.
So what’s the problem? For the past 150 years, the goal was to address the same challenge that Sun Valley faced: not a lack of water, but too much water during the brief, intense rainy season. So Southern California built storm sewers and concreted the rivers to efficiently carry all that fresh water into the ocean.
The answer to the drought, therefore, is to stop wasting this valuable resource. It does not have to look like this.
If CA captured and used the water that already falls in CA, CA could turn off the tap from the north and leave that water for farmers. Just as we discovered in CA that sunlight falling on every rooftop can be harnessed to generate energy, right at the place it is used, we can capture the water that falls on those same landscapes for use where it’s needed. In fact, the Los Angeles non-profit TreePeople has been demonstrating for years that every type of building or land use can do what Sun Valley has done, or what solar panels do for energy generation—decentralize.”
How much water do we use?

Who is the Most Important Customer?
Is it the Local Government? County, City or Town? The water utility? The homeowner? Or is it the Community?
The issue is not mitigating floods at all costs. It’s capturing flood water and capturing normal rainfall, effective/efficient use, and re-use/recycle of water by every home and every business.
Local Goverment must play a role in designing and installing water storage systems. But homeowners can play a significant role too.

How can a homeowner capture normal rainfall?:
Suzy Morris, who lives in New Zealand shared some photos of a harvesting system the family installed behind their garage. They purchased 7 blue barrels and assembled them (see below):
The barrels were painted white to keep the water cooler and installed behind the garage:

Will Riviera Country Club (in LA) continue to look like this?
If local government, communities and individual homeowners do what they should do:
- Capturing flood water
- Capturing normal rainfall
- Effective/efficient use, and re-use/recycle of water by every house and every business,
Riviera CC will be a gorgeous golf course!
