Is there any irrigation system in the area now--are you trying to change a spray system to drip, or is it completely non-supplied at this point?

From Home Despot - Skip the "kit"; I use the 1/2 inch black pipe. Add drippers using the punch tool. Use the bags of 25 flag style drippers in 1-2gal range. These drippers are less likely to clog, and the flag can be removed and cleaned if they do. Space drippers depending on water needs - most of mine are 12" to 24" apart. There are adapters to connect the line to 3/4" pipe thread OR 3/4" hose thread (slightly different) Connect your dripline to the output of your sprinkler valve. Ideally you would have an inline filter, and a pressure regulator for your drip system. If you place these at the "head" of the setup you will only need 1 for all the drip circuits. A shutoff valve is very handy also for when you need to work on the system.

I also use Netafim Techline which has the drippers inline. It uses metric connectors so it's a bit of a pain, and is only available online of from an irrigation supply house.

I've found dripworks to be far superior than local big box stores. They're a very good quality, easy to use and easy to "reuse". Their "Heart of the Garden" kit should be more than enough to start you out. http://www.dripworks.com/category/heartkit

Your area is small enough that it should be easy to figure out how many sprayers you'd need. The plants you listed aren't going to like drip very much, or getting their main stems soaked. I'd suggest something like the mini jet sprayers, though they have an excellent customer support that should be able to suggest just what you need. http://www.dripworks.com/product/Q_MSBU

Best prices I've found for timers have been on Amazon.

dak56, I am a gardening beginner here so bear with me - if my plants won't like drip (which I thought the point of was to water the roots more directly) but won't like their main stem being soaked (oops which I am doing now with the shower sprayer) then how DO they like to get water?

Nursery info doesn't mention these details!

Drip irrigation delivers water vertically down, imitating a marsh/riparian type environment. Your plants would survive on drip, I have neighbors that have all their natives on drip, they're alive, but not what I would call thriving.

From my experience, drought tolerant plants do better with a watering system that imitates rain, like sprayers or sprinklers, the water spray extending into the plants dripline. Rain is not going to direct all of the water onto the stem or trunk, it's going water the whole area, it's not that you never get the trunk wet, sorry if I implied that.

OK so I should get a system with sprayers and locate them near the plants but not spray directly on the main stems? For example locate a sprayer between 2 plants?

See, I thought drip just meant that it is a self-watering hose type system.

I would go more with bubbler heads. With spray heads you will waste so much water and destroy that wooden fence.
Spray heads also need adjusting more IMO to keep at just 1 foot and really thats almost impossible.
Eventually the roots will be beyond the drip line of each plant and will grow and reach for the water if you were to put bubblers in between.
You might think about soaker hoses also. Most are black made of recycled tires and you won't notice them.

This little DIY drip irrigation system works perfectly for me. Here is a link:
