M Administrator Wright inquired about the effect of this in Indian River Heights, for instance, and Public Works Director Davis advised that in that area we have definitive back lot drainage, and it is simply a matter of sloping to get to the swale. He emphasized it is not the intent to get into something costly, but we do want people to think about drainage when they design their house. Commissioner Bird did not want this to require hiring an engineering firm or anything that will increase the cost of the homes considerably. Commissioner Wodtke wondered if we may not need some flexibility with the standard of the 10 year 24 hour storm as he felt, in some cases, people may not be able to retain 7.5" of water on their site. Administrator Wright asked about areas where we might have a problem with this standard, and Director Davis felt some of the problem would be in unplatted metes and bounds subdivisions with no rear lot easement. He pointed out that while the rainfall in the 10 year 24 hour storm may be 7" or so, the runoff from the lot is not that much. but he felt we could relax that require- ment if desired. Commissioner Wodtke felt possibly we should try it first and see just how much problem it does create, and Vice Chairman Lyons agreed. Commissioner Bowman brought up the problem of the runoff being legally routed off the site into a maintained drainage system as she believed the water management districts are very jealous of their ditches. Vice Chairman Lyons asked if anyone wished to be heard. Georgia Allen of Roseland confirmed"the.re are cases where the requirements for elevation of new houses have caused problems, and she agreed that people need some assurance their yards will not be flooded. It was determined no one else wished to be heard. 53 Boa 64 PA,UE.510
