The Garvanza Park Stormwater Best Management Practices (BMP) project will capture and clean more than one million gallons of rain at a time for later re-use and infiltration into the soil beneath the park.

Recently retro-fitted Steelhead Park built by North East Trees to filter street run-off water, Los Angeles’ Elysian Valley neighborhood. |
An innovative below-ground system will use the cleaned water for the lawns in the park, replacing water that is now imported. The project will help keep the Arroyo Seco clean and healthy by reducing the annual pollutant loads of part of the water that drains into it about 90 percent.

A storm drain that passes under the park currently carries water draining from the hilly neighborhood above the park to the Arroyo Seco. The Garvanza Park Stormwater BMP project will clean up part of this water and store it in two large underground chambers. Water from one chamber will slowly soak into the soil, while the stored water from the other will be used to irrigate part of the park’s large lawn areas.
Project Location:
The project will be built beneath
the large, open grassy area between
the skate park and Meridian Street.

Proposed location, in part of park north of skate park and east of the ball field. |
Construction Schedule:
March 2010-December 2010
Monday to Friday
7:00 a.m. to 6:30 p.m.
Budget:
$3.1 Million, design + construction
Construction Impacts:
During construction the baseball field, skate park,
picnic and play areas will remain open, and the
construction site secured. No impacts to park use
are anticipated after construction completion.
Funding Source & Responsible Agencies:
The project is funded by state and local funds;
design and construction is managed by North
East Trees in coordination with the City of Los
Angeles, Bureau of Sanitation.
Project Benefits:
• Rainwater will be captured and used for
irrigation, saving precious potable water.
• This project will help keep the Arroyo
Seco, Los Angeles River and the ocean
healthy and clean.
• Improved sustainability for the park as
varieties of grasses that use less water will
be planted.
• Better health for the large mature oaks and
other trees on site, which will be carefully
protected during construction and after.
• More trees for the park as four poorly
growing trees will be replaced with twelve
or more healthier trees.
• The new irrigation system will keep your
park turf green and healthy with less water.

The first Green Street in Los Angeles was built by North East Trees: water is collected from driveways and allowed to soak into parkways. |
We want to involve you in this next step to clean our water. We will hold several neighborhood meetings, distribute questionnaires and ask for your opinions. Please see the meeting schedule and if you have any questions or concerns please contact Michelle Vargas at: (213) 978-0333.
