I have a 9' strip of land nestled between my driveway and the neighbor's fence. I'd like to plant some rows of blackberries and make some raised beds with tomatoes and vegetables here since it's one of the few locations not shaded by trees on my small property.

How far from the concrete and fence should I plant things? Can I make the raised beds go right up to the concrete and right up to my neighbor's fence? From the survey it looks like the fence is right on the property line.

I live in North Texas (Zone 8a) so I'm worried the heat retention and radiation from the concrete driveway will be an issue.

I think a raised bed, if you can irrigate it, should be safe right up to the driveway. It's a light colored drive, which will warm up, but not near to the extent that blacktop will, and it has the benefit of reflecting light onto the undersides of leaves. Leaves have more concentrated chlorophyll above than below, but the undersides are still capable of absorbing quite a bit of additional light, greatly benefitting the plant...

... Back on topic :P, I would leave some space between your raised bed and the neighbors fence, perhaps 18" or so, to walk in. That is nice for the neighbors in case they decide to alter the fence somehow, they won't be worried about walking in your raised bed or damaging your blackberry bushes. Also, I'm assuming you'd plant the blackberries in the back, leaving space behind them is good, as they can spread by suckers, and may appear in the neighbors' yard unless a barrier of some sort is installed.

If that fence is from treated lumber (probably not, by the look of is, but better safe than sorry), or even a previous fence, the surrounding soil may be contaminated with arsenic, which is absorbed by plants and can pose a health hazard. Other than a root barrier, you could get a sample tested for arsenic, and go from there.
