Really not my field of expertise, folks, but a colleague of mine and her fcukwitted husband were dumb enough to ignore the maxim that if it appears to be true, then it probably is. Accordingly, they bought themselves a fixer-upper property on a slope within a small canyon. Unfortunately for them, like most Southern Californian canyons, a paucity of vegetation leaves the area prone to mudslides- and we have heavy storms forecast for this weekend. Now, Civ Eng was my dad's gig, not mine, and he'll be getting a call in the morning, but he's used to big, captial projects that are planned years in advance and I figure you lot are much better versed in improvisation. I'm a little bit sceptical about my colleague's plan, which as far as I can tell involves just laying plastic sheeting on the slope and hoping for the best. I'm wondering if any of you might have some better ideas about controlling, or at least minimising the risk and damage. Preferably ideas that don't involve any equipment that can't be begged, borrowed or stolen from friends, neighbours or The Home Depot. Labour is not a problem I can PM the address if anyone wants to take a look at the topogaphy on Google Earth. Possibly some photos tomorrow afternoon. As regards the geology, I don't have a clue. The soil is bone dry because it hasn't rained properly here since about March and is fairly sandy. I don't know if this means that it's going to be better at retaining water, or whether this means that it's going to be more prone to liquefaction. Any help you can give me would be most apprecated, both in terms of practical plans or just general things to look out for and consider. If you want to rip the p1ss, go ahead because, quite frankly, I don't like the dappy bint that much anyway and neither does anyone else. We just want to be able to say that we gave it our best shot. Cheers.
