LEIT'S UNIQUE ABILITY TO OPERATE USING
AMBIENT LIGHT AS POWER SOURCE ENABLES
CONVENIENT PLACEMENT FOR IRRIGATION
CONTROLLERS ALONG THE ALAMEDA CORRIDOR
The Alameda Corridor is an underground railway linking the Long Beach Port with downtown Los
Angeles. The subterranean system improves the flow of cargo in and out of ports while minimizing
the effect of freight movements on local communities. Industrial development like this often has
a negative effect on the surrounding area. To mitigate these effects the Landscape Architect, Lynn
Capouya, included landscaped areas with appealing plant material and covered seating.
The mitigation areas are found closest to the railway, which is often isolated between existing
roads. Each landscaped area needed irrigation to support the plant material and a controller to
operate the system. In her design, Lynn noted difficulty locating existing power sources along the
corridor. The LEIT controller was a perfect solution for this issue because of its ability to operate
using ambient light, without need for AC power/wiring or batteries.
"The corridor project was complex and filled with issues regarding power availability, permits
and the coordination of multiple jurisdictions. We found that ambient controllers simplify as
well as expedite the installation process," says Lynn Capouya of LCI, an established Landscape
Architecture firm in Southern California. "Our agency specified LEIT controller on past projects.
We found them to be a dependable and permanent alternative to conventional controllers whenever
access to power was an issue."
Vandalism and theft were also concerns on this project. The freedom to 'hide' the controller
is another advantage of a non-power dependent irrigation controller. "LEIT can be installed
anywhere. We were able to position it out of sight from vandalism in the municipal environment.
For extra protection we specified a VIT/Strongbox (model number SB18 SSLT), a stainless
steel enclosure for each controller on the system," explained Lynn. This enclosure is designed
specifically for use with LEIT controllers because of the Lexan top, which allows light into the
box.
To control irrigation of the plant material, fourteen LEIT X Series controllers were used along the
entire corridor. The "ease of installing LEIT was greatly appreciated," says Larry Irvin of Valley
Crest Landscaping, a corporation with several decades of experience in the landscape installation
industry. Larry also mentioned "labor savings were always significant whenever we installed LEIT
controllers because of the lack of complications associated with AC power."
This sizable project utilized LEIT controllers to minimize the complications of the job. The
simplicity of installation and freedom of placement made LEIT irrigation controllers the logical
solution for keeping costs at a minimum while expediting the construction process.
