I took some pictures and uploaded them to Photobucket. I will also upload a sketch with what is currently in our yard and some ideas we have for possible changes. I have a sketch with exact measurements and locations of trees, etc., but it's too big to scan in so I'll have to do a basic sketch on some smaller paper as soon as I get a chance. The dimensions of the backyard are almost exactly 80' wide by 80' deep. It appears to be deeper than it is wide, but maybe that's because the veggie garden (which is 15' wide by 47' deep) takes up a good chunk of the east side of the yard. I really like the idea of going to some favorite nurseries and collecting business cards from designers. I was trying Google searches and met with one company whose work looked nice, but it turns out that they don't do design work without being locked into a contract with them to do the bulk of the landscaping work. We'd have to sign a contract (telling them our budget range) and they would draw up plans within that range and do most of the work, subbing out stuff they don't do themselves, with the design being part of the package deal. I think I'd rather work with someone who has more flexibility in allowing us to do parts of the work ourselves without being penalized for it. lazygardens and butterflygardening: Thanks for the helpful links- I am reading through them! alygal- We love the idea of raising chickens (or ducks!), but unfortunately our city doesn't allow them in residential areas. Some of the towns around us havejust recently started allowing them, so maybe it will be a possibility in the future! Here are some of our current ideas for making our yard more attractive and usable in the ways we'd like to use it. - Possibly ditch the sandbox, although I am torn because the kids do use it when it's nice outside. The problem is that it's so close to the house that they always come in still covered with sand, AND it's location really limits the width of the planting bed around the breakfast nook. If we keep the sandbox, I think I'd at least make the flagstone path along it more narrow to allow for a slightly wider bed there. - Widen pretty much all of the beds to allow more layered planting (to increase attractiveness and privacy in the yard). I would also like to have a nice bed along the patio and around where the sandbox is, so basically be left with an area of the grass in the middle of the yard. - Possibly add a slight berm along the garden fence and plant a variety of shrubs and small trees to make the garden less prominent since it's not much too look at most of the year. - Make the patio more usable by extending it a little deeper (it's now 20' wide by 10' deep). - Add something to get more shade on the patio. It gets shade starting in the mid-afternoon and through the evening from our neighbors house to the west, so I don't really want to add a hard cover (my husband's idea) because I think it would detract from the look of the house. I am thinking a well placed tree would eventually have the right effect (and I'm content to use a patio umbrella as needed until then). - Add a screened in gazebo (about 12' x 12') south of the patio area toward the south side of the yard for dinners and entertaining. My husband is a mosquito magnet so he really wants this for enjoying the yard in the evenings. - Add a structure toward the southeast corner of the yard (about 8' x 10') to be used as a playhouse/garden retreat. I picture it looking like a little cottage style potting shed more than a mini playhouse, so that even after the kids outgrow it, I can still enjoy it as a garden retreat. - Revise current pathways through the yard and add pathways as needed to new structures, to the veggie garden/shed, etc. Would like to maybe use some reddish flagstone in addition to the buff ones we currently have and mix them up a bit as the buff looks so bland to me against our house. - Possibly cover the patio with flagstone to make it more attractive and more cohesive with pathways. Thanks for any advice or suggestions you may have. Here is a link that might be useful: Backyard Pictures

You may find the nothing will readily establish there due to the beds being filled with roots from the long-established trees. You might need to use large pots or planters with saucers under them to keep out tree roots if they are aggressively rooting species. For that you would need to get the trees IDed if you don't know what they are, and then research growth habits.

Beware of landscaping for low maintenance. Over the years, quite a few of my neighbors have replaced their front yard grass with ground covers and shrubs "for lower maintenance". To them, that means a garden service coming twice a year to cut down perennials in spring and fall when they die. They also cut the tall weeds down to ground level (e.g. a large patch of wild goldenrod reached 8 ft before it was cut to the ground.) The original ground covers and perennials are a mess since they're never weeded, and some like Bishops weed and lily of the valley, are taking over. Some areas (e.g. low sedum) are so covered with weeds that the original ground covers are not that visible. The shrubs are overgrown, hanging over the pathways and sidewalk. Overall a very messy look that cost them more money than they would have spent by just hiring a lawn mowing service and keeping their original evergreen shrub foundation bushes. If I were you, I'd concentrate on some hardscape improvements like that hot tub idea and leave much of it as lawn for the children to play on.

people incapable of sorting through nuances = HOA boards Looks like your soil is very sandy, so that it could turn out to be murder trying to establish and maintain lawn grasses on the small section of level ground involved with this project - let alone on the sloping part. And since you have a Mediterranean climate July is just about the worst possible time to install a new lawn - wait until later in the season if at all possible. Better yet seriously reconsider having any lawn on that site at all. As for your specific climate area (California has a large number of different climates) and what specific plants might work for your purposes a latter day copy (various editions have come out for decades) of the Sunset Western Garden Book will have such information.
