Calling all Rain harvetsers in Tuscon,Oroville-Arizona

I am currently visiting the Arizona region and am trying to find those who have worked in rain harvesting from either roof runoff or street runoff(similar to Brad Lanchasters works)
I'm hoping to document and share the works in this region with my permaculture community in Yakima of Washington state.
If anyone would like to do a "show and tell" of their works, I would be glad to drop by, for I have 2 free weeks in Arizona.
From what I have heard, Monsune season is close at hand.

If of course if some of you have web links to some of the local projects here in Tuscon or Orovalley, it would be worth my visit to the region, I have been rather keen on finding some kind of local earthworks project out here that utilizes the monsoon rains, so far all I have seen is the result of mass erosion, perhaps I saw on example  of water retention design but not quite flashy enough.
A link would definitely help or perhaps reference to public demonstration sights.

Here is a link to the neighborhood in Tucson that Brad Lancaster has been working with since the early nineties...  http://dunbarspring.org/
Maybe someone at this website could link you up with other projects in the area?

I don't know how this neighborhood is arranged for visiting other than when there are tours or projects happening.  We missed hearing about this until after out last visit to Tucson...I intend to check out the area next time we're there.

If you are still in the Tucson area and looking for rain collection info, see the folks at Watershed Management Group.
