• 21 <br /> order to achieve that goal, according to the <br /> computer model, required a five-acre minimum lot <br /> size and a 4% impervious surface ratio. <br /> Waddell expressed concern that perhaps the <br /> computer model was incorrect. Collins responded <br /> that the watershed Work Group, in its many <br /> • discussions, had not questioned, but had accepted <br /> the computer model itself. <br /> Eddleman expressed concern with the number of <br /> homes which might already be non-complying. <br /> Yuhasz stated that he felt it was more likely <br /> two-thirds were out of compliance and only one- <br /> third in compliance. <br /> Eidenier expressed concern with the number that <br /> would become special exceptions and would require <br /> Board of Adjustment approval for a variance. <br /> Collins reviewed again some of the lots on the <br /> chart he had prepared noting those on cul-de-sacs <br /> and those with long road frontage. In a new <br /> subdivision, the division of the road frontage <br /> equally for all lots would address some <br /> situations where the impervious ratio is <br /> exceeded. This is an example where the design of <br /> the development itself determines in great <br /> measure whether or not they will comply. <br /> Eidenier expressed concern again with the <br /> redesigning of lots when perhaps increasing the <br /> percentage by one point might alleviate the <br /> problem. <br /> Eddleman expressed the concern that private <br /> roads, with washed crushed stone were not really <br /> impervious surfaces. Collins responded that in <br /> the early 1980' s when the impervious ratio issue <br /> first began, there was considerable discussion as <br /> to whether an unpaved road was an impervious <br /> surface. He noted that most of the information <br /> available, because of the impaction on an unpaved <br /> road, was just as impervious as a paved road. He <br /> noted that perhaps the intent in leaving it out <br /> of the ordinance was a means of addressing <br /> hardships. <br /> Best stated that the Transportation Consultant <br /> and the committee has included compaction <br /> standards in the Private Road Standards because <br /> the transportation engineer believes that unpaved <br /> roads are just as impervious as paved roads. <br />
