Want to know more about where to find green infrastructure projects around the country? The National NEMO* program has an interactive website for you! The Low Impact Development (LID) Atlas was created by the Connecticut NEMO Program and the California Center for Water and Land Use “to highlight innovative LID practices around the country.” It’s pretty neat to cruise around the country looking at various projects. Too bad there aren’t more listed – a map like this is only as good as its informants.
Unfortunately the site wasn’t set up as a wiki, so you have to be a member with a login to post your project. Right now Elmer Avenue isn’t up there – I’m trying to get it posted.
If you know of a project that should be on the map, you’ll have to contact your state NEMO rep (and hope that you have one).
*The acronym is meaningless today but used to stand for Non-point source Education for Municipal Officials.
That’s what some people are calling the new green street retrofit – I guess because the swales look like little canals. Or maybe it’s because the street is just so pretty right now, after the plants have been in the ground for a couple of months. Emily Green, LA Times, calls it “The Dry Garden,” and Sunset Magazine’s Fresh Dirt blog says it is “a model, we hope, for the future.” I like the Mother Nature Network blog’s headline, “Elmer Ave. in Sun Valley, Calif., is ready for stormy weather.” You can read the most complete coverage on LA Creek Freak in the piece that has generated the most comments of any posting I’ve seen so far, “Elmer Avenue Green Street Project Explored.”
In case you haven’t been able to get out to see the street yet, here are a few more photos from earlier this month.
The plants in the swales are growing and blooming so well; I’m looking forward to seeing how they weather the summer heat.
I can’t give the residents enough credit for having the vision and grace to allow their street to become this showcase for all of Los Angeles, for how we can turn our streets and yards into gardens that harvest the rain.
Department of Water Resources Director Mark Cowin said “While the increase in deliveries is good news, we will continue to have a water supply crisis until we improve our conveyance system, increase storage and resolve the complex environmental problems of the Delta.”
Solutions? We need to use water, of course, but we are also victims of engineering. The system is designed to direct good rain into storm drains and send it to the ocean, bypassing the soil and groundwater basins. This way we lose enough water every year to supply over a million people. In the words of Dorothy Green, we need to unpave LA!
By turning yards into rain gardens and streets into water recharge facilities, we can ensure we have enough clean water for the future.
We took a small step in that direction with the completion of Elmer Avenue this May. Elmer recharges 16 acre feet a year, which is enough water to replace that used by residents of the street plus a few more households. Plus with their new drought tolerant and native landscaping and education about water conservation, we expect the residents will be using even less water into the future.
We don’t have enough parks in Los Angeles. Given the expense of land and the reality of built-out cities, we need to think about how we can create more parks in urban areas. We need to be creative in converting even small scraps of vacant land into places where people can enjoy nature, walk their dogs, and play. Almost five years ago a small group of people in Altadena got the idea to turn a small barren bit of dirt into a park for the community. Just 8,000 square feet and owned by the County’s Roads Division, the parcel was too small to be a true park. Also working against it, the land was on the border of Pasadena and Altadena – in the unincorporated County but with water from Pasadena. But this neighborhood had no park and thus the idea was borne – why not create a “pocket park?”
The design included native, drought-tolerant plants designed to bring the mountains into the city, and dry wells to collect and percolate all of the rainfall, eliminating sheet flow runoff from the site.
Several more grants and lots of hard work later, the hard, barren ground is blooming. We wanted to demonstrate low-water use gardening that people could replicate in their own yards. The park was completely a volunteer, community-led project from start to finish. It would not have happened, however, without the support of Supervisor Michael Antonovich and Metropolitan Water District. Mountain View Cemetery, Foothill MWD, Pasadena Water & Power, plus the members of Neighborhood Church were also major supporters. The list of supporters is long.
Here are a few more photos of the park, which is at the intersection of Marengo and Woodbury. We named it “Old Marengo Park” to acknowledge its origin as left over land when Pasadena and the County aligned Marengo Avenue. What neglected scraps of land can you turn into a park in your neighborhood?
