19 <br /> 72T; <br /> MEMORANDUM , <br /> -nil " <br /> TO: Emily Cameron, ASLA Planner II <br /> FROM: Paul Thames , County Engineer <br /> DATE: July 22 , 1994 <br /> SUBJECT: Wyngate II <br /> As per your request. I have reviewed the materials provided <br /> to me and related to the above referenced project. Earlier <br /> this year I also visited this site with Warren Faircloth to <br /> inspect the dam. Regarding this project, I have the <br /> following comments: <br /> 1 . I generally agree with the recommendations contained in <br /> the engineering report submitted by Civil Consultants , <br /> Inc. The dam does not appear to present a high hazard <br /> ( threat to human life) except in a case where a vehicle or <br /> pedestrian is in the immediate vicinity of major breach or <br /> blowout at or near the instant of the blowout. It is also <br /> possible that someone could try to cross an inundated <br /> section of NC 10 or one "of the inundated drives downstream <br /> and be injured. Conditions where such accidents could <br /> occur should be fairly slow to develop ( except in the <br /> immediate vicinity of the blowout) and of limited <br /> duration, however, reducing the probability that life <br /> threatening situations will arise . <br /> 2 . The engineer' s recommendations related to reconditioning <br /> of the dam by lowering the water level, re-channeling the <br /> drainage way behind the dam, improving the emergency <br /> spillway, providing a standard overflow pipe, removing <br /> small and dead vegetation, etc. , are essential in <br /> promoting the stability of the dam structure. It is <br /> important that the approval process for this project <br /> incorporate whatever means are required to insure that the <br /> recommended measures are accomplished satisfactorily. <br /> 3 . It is my opinion that all large trees on the dam should be <br /> removed as soon as possible. Some of the trees that are <br /> still alive do not appear healthly. Some appear to be <br /> perched somewhat precariously on the edge of the dam <br /> embankment and vulnerable to being overturned in high <br /> winds. It would be simpler to remove the trees while <br /> construction is taking place in the vicinity. Decisions <br /> about removing trees should not be left up to future <br /> homeowners. <br />
