Right you are Deborah Behrens to clarify on appropriate ELF discussion on this forum. I felt the discussion of the biology and physics was sort of getting off track - I agree, construction issues around ELF, or other things of concern is very appropriate - I just get enough email so that I have to be selective, and it seemed the political, biological, physical issues of how ELF does or doesn't cause health concerns don't seem relevant to building cohousing. At Sharingwood we put all our power underground which helps the issue tremendously, not to mention the esthetic. We had a group come out and take ELF measurements at our two transformers. At a distance of 2 feet from either there was no reading. Our electric cables are in a 6 inch thick concrete box and buried 4 feet in the ground. The box has a large green metal cover with a bunch of warnings on it. We specifically requested the green colored covers,(rather than white!) and they cost a little extra but they blend into the background shrubbery nicely. We have 4 remote power kiosks which have 4-6 power meters on them. The kiosks are two large treated posts about 8 feet high, Three feet apart with a half sheet of plywood between them, then covered with a cedar shingle roof and front. Each house runs an underground line to the closest kiosk. We put all the power meters on the back of the kiosks (which makes the power meter reader grumble because she has to get out of her car to read the meters) and we use the fronts of the kiosks as outdoor bulletin boards. The power kiosks are at the edge of the road, sort of out of the way and again, measurements for ELF dropped off to 0 at 2 feet. Having clusters of remote power kiosks was something we had to argue with the county planners about. They wanted power meters on each house, but when we asked them why, they all scratched their heads and could not come up with a reason why not. We pointed out a couple example developments which did remote kiosks, and since that was "precedent" they dropped the issue. We didn't tell them or the power company we were going to put the meters on the backs of the kiosks, but hey, they didn't tell us we couldn't! Having the outdoor bulletin boards is nice. One of them is full of kids art, one is our entry bulletin board with info about our community. The other two don't get used much. Rob Sandelin Sharingwood
