If anybody here has done any public work involving raingardens in Florida let me know! Since I have been working for my firm here in Tampa we have completed 4 to 5 significant “raingarden” type projects; one of them being a LAP FDOT streetscape for Tarpon Springs. Public work involving stormwater management in a creative way is far and few…[Read more]

Hi to all the Wildcat LA’s. Bear Down!

Glenn, and all
True that clients like to see green plants in the summer. Which is why some designers advocate a mix of native (80%) and non-native (20%) plants. The non-natives – which may require some summer water – stay green while the natives go summer brown.

Jon Q. asked about construction documents for green street work. After mining Portland’s BES site, i found a lot. Very helpful.

Since many of our native plants go dormant in the summer as a survival technique to dry summers, I’m saying “advantageous for the summer-dry months” as it relates to the clients who prefer to see green plants and leaves still hanging onto their Buckeyes. Alternatively, Juncus, Western Sword Fern, and Iris, for instance, often receive summer water…[Read more]

Glenn Do you really need to irrigate these plants that you mention in summer? They are native to N California, and so in a “natural” context do not get any summer water. Why would you need to irrigate them in a cultured situation?

The “felt” fabric. Blanc’s installations has two layers of fabric that he drips his water/fertilizer solution through. This is a non-soil installation. The plants root into the fabric and fed by the solution.

to David — your response was great. thanks. we are about to over-seed an area with native wildflower mix. have to say, had a really good chuckle, more like chortle reading your comments. then had this amazing image of you talking to some folks out in your mojave neck of the woods about carbon sequestration (mostly because I have been in that…[Read more]

I was wondering what sites residential designers use to find certain products or materials. Let’s say you want to find certain types of outdoor porcelain tiles, sculptures, water features, etc. Are there sites out there that are relevant for us to use? And if so, would anyone like to share these?

David, I love your common sense approach!!!

Oops — just saw the link in your second post — thanks, David.

Still would be great to read the actual pub to know what was included in the study.

Wow…. and I thought my comment was long winded!

This is great, though, David. I appreciate it. It is helpful to have to have a peer reviewed pub in this conversation (it means i better try to find the one I was referencing!). And it does run contrary to the prevailing wisdom in the “green” community regarding turf. Do you have a web link or…[Read more]

This is interesting:

‘Corrected’ UC-Irvine study shows turfgrass to be positive sequester of carbon

Scientists from the Department of Earth System Science at the University of California – Irvine recently published a paper in the journal Geophysical Research Letters on January 22, 2010 titled, “Carbon Sequestration and Greenhouse Gas Emi…[Read more]

In response to John’s question “how would you propose to reduce emissions and increase sequestration through design” in addition to my comments below about how to reduce greenhouse gas emissions – landscapes can also play an active role in sequestering carbon through thoughtful plant selection and soil stewardship. Research has shown that…[Read more]

I believe the solution is to first accept the dual responsibility built landscapes hold in both causing environmental degradation AND protecting and restoring the ecosystem services we depend upon.

I agree with David, we can not and should not eliminate turf completely from our landscapes. There are many scenarios where mowed lawn is the best…[Read more]

I have not read the article, Heather, David and Reid, but I think the basic point is good one — maintenance should be consideration in designing a “sustainable residential landscape.” Even here in the SW, we will design what we think is a more sustainable landscape, and put in a water harvesting swale with cobbles. As it turns out the maintenance…[Read more]

David your are correct!

@Reid – Hahahahahahahahahahaha!

I love to laugh out loud! It’s good for the body. Relieves stress, improves circulation.

Stupid Article!

This study also “compare(d) carbon sequestration to nitrous oxide and carbon dioxide emissions from lawn grooming practices.”

I have news for anyone willing to listen. Lawn maintenance doesn’t produce carbon “di”oxide emissions. Lawn maintenance produces carbon “mon”oxide. Carbon monoxide produces carbon dioxide which in turn is used by plants…[Read more]
