Some things to study and work on implementing as time and seasons allow:
http://www.tenthacrefarm.com/2013/10/front-yard-rainwater-catchment/ and http://www.tenthacrefarm.com/2014/02/using-swales-in-the-landscape-part-2/ (and really probably just browse the "water catchment" tag in that whole blog)
http://brinkoffreedom.net/homesteading/how-to-plant-a-cherry-tree-guild/ and http://midwestpermaculture.com/2013/04/plant-guilds/ - that second one especially, tho it will need to be translated to PNW climate needs
I threw out my back this last weekend trying to lift too many bricks at once, so of course this is a good time to ponder building earthworks. Our seasonal rainfall pattern, though, it is a menace.
