We have taken rainwater for granted or treated it as an enemy sloping driveways to send rainwater to the street and nearest storm drain since the 1930's. Now the LA River Watershed is taking a different approach. Why not the Ballona Watershed which sends Billions of Gallons of Water to Ballona Flood Control Channel and into the Pacific Ocean, Santa Monica Bay?

Instead of tossing stormwater into the sea, Los Angeles wants to capture more of it to replenish local groundwater supplies. But that is neither cheap nor easy.

Lost Creeks of the Ballona Valley offer an opportunity to remove concrete channels, 
day light streams children can enjoy, and infiltrate rainwater into our aquifers.

The light blue lines on the map represent earlier streams. Now our precious rain water goes into storm drains
along with contaminants from our streets.This polluted runoff flows to Ballona Creek, then into the Pacific Ocean.

FACT: Marina real estate, boat slips basins and yacht clubs are all on long-term land leases of 50-60 years. Some have expired, some have been renewed, and others offer opportunities for revision..

FACT: Santa Monica Bay Restoration has advocated opening our Ballona Wetlands to the ocean. See videos by Travis Longcore and Margot Griswold for a greater understanding of our opposition to this.

FACT: A flood plane covers large areas of the lower Ballona Watershed (Venice, Marina del Rey, Ballona Wetlands and Playa del Rey). Sea level rise, a tsunami, or a huge storm event could flood the lower Ballona Watershed. 
FACT: 950 acres of Ballona Wetlands were chiseled out to create Marina del Rey small boat harbor and recreation area by the U.S. Army Corps of Engineers under U.S. Congress Documents 389 and 780. U.S. Congress, Los Angeles City and Los Angeles County provided funding in almost equal parts.
FACT: U.S. Congress Documents 389 and 780 designated 41.9 acres for Oxford Lagoon Bird Sanctuary. Only 10.7 acres were actually set aside.
FACT: 90% of all our wetlands in Southern California have been built on or paved over. 
FACT: Last 150 years have been the wettest in 4,000 years. Our present drought could continue for 100 years. 
FACT: 120 miles of intermittent streams, 47 miles of perennial streams, and 3.8 square miles of wetlands in Greater Los Angeles existed before storm drains were installed early in the 20th Century.
FACT: 0.61 square miles of Ballona Wetlands and 24 miles of creek existed before storm drains were installed early in the 20th Century.
FACT: Los Angeles imports around 85% of its water from over 200 miles away. It uses 30% of its state electrical power to deliver this water.

Underground Gas Storage: Leakage Endangers Human Health from Leakage

Underground gas storage of unrefined petroleum based gases is a cheap method compared to steel tanks, but is associated with cancer plumes and poor health of everyone downwind.

This page lists resources to keep you informed, more informed than newspapers now a days are willing to publishing about their advertisers.

SoCalGas (Sempra Energy) Underground Gas Storage Field in Playa Del Rey, CA - Aerial

SoCalGas Aerial Screen Shot 2016-02-08 at 11.13.55 AM_size800.png

Lurking below the surface of the Ballona Wetland is 7 to 8 Billion Cubic Feet of Natural Gas that SoCalGas (Sempra Energy) imports from Texas, Oklahoma and other areas.

The circumstances are very similar to Porter Ranch. Past History shows leaking oil wells have provided a pathway for these gases to migrate to the surface.
