Very nice! Sounds like you've got a lot going on in a small space. I got a year of growing under my belt in my yard in Klamath Falls, OR last year, which has a climate not entirely different than here. I'd say the major differences are in the diurnal temperature swing there is greater, and the summers are cooler. I had great success with potatoes, brassicas, chard/beets, arugula, leafy greens in general, tomatillos, wonderberry, etc. I had limited success with mellons/winter squash, corn, and tomatoes, as there just isn't enough heat up there in the summer for long enough for the truly heat loving plants. I think that would be different here (Most years. Remember the summer of 2005? it was cold and rainy until the end of June).
I also started an edible forest garden, which was doing well, though it's hard to say while only being on the land for one year. The old sleep, creep, leap seemed to be in effect, as most woody perennials I planted just sort of sat there most of the summer. A few put on some new growth in the fall though. One species that took off and grew significantly throughout the summer was gogi, which I found interesting and would definitely try here.
Is the rainwater collection permit a city thing? I know one must register their property with the state if they have over 200 gallons of storage capacity (2500 gallons max), but it sounds like it's free and guaranteed, they just want to have record of it.
http://waterrights.utah.gov/forms/rainwater.asp Definitely worth doing though. We do get enough summer rain (most years) that even somewhat minor storage capacity would be worth it. I cringe every time a summer thundershower hits and the gutters all overflow with water that could be used in peoples yards. And often times, those people have sprinklers running in their yards during the thunderstorm! Anyway, the optimist would say that just shows how much opportunity there is for improvement. One thing I would like to see getting implemented around town asap is just the rain garden idea. Everyone seems to mound the earth in their yards so heavy rain and snow melt just flows off into the gutters instead of infiltrating into the soil. Of course, everyone has the right to do what they'd like in their yards, but it would be nice to see some voluntarily make positive changes, and it would be really great to see the cities do such things on public land.
