NfN 55323-0066 <br />Re: Dickey and Coffin Properties <br />Dear Ms. Mabusth: <br />I received some information last week with respect to the above mentioned proposed subdivision. <br />Unfortunately I have not had sufficient time to review the information, let alone have our <br />Engineer or Hydrologist look at it. Hopefully I will be able to accomplish that this week. <br />I am sending this letter because of the Planning Commission meeting this evening. I would like <br />them to know that the Department has some serious concerns regarding this proposed subdivision <br />with respect to drainage and runoff, and what it might mean for long term mninteiiance of the <br />Luce Line State Trail. If and when this proposed subdivision gets completed it will be adding <br />a large amount of additional hardcover to the area. This will definitely increase drainage and <br />runoff with respect to our trail <br />Further East on our trail we are now starting to notice some serious problems with a situation <br />such as this where subdivisions have added more and more hardcover to areas further back from <br />the trail This has resulted in a lake being formed where there once was nothing, and our trail <br />has subsequently turned into a dam. Needless to say the trail was not consiructed of material <br />sufficient to function as a dam. <br />I have noticed the proposed creation of a new' pond immediately adjacent to our trail on the <br />Coffey property. I am concerned about that possibly creating the same type of situation I <br />mentioned above This needs further research. <br />Plans have identified some existing culverts th.at are currently in place on the Luce Line Trail to <br />handle some of the additional runoff associated with this subdivision.. What should be mentioned <br />here is th.it some of those culverts arc ones that were originally put in by the railroad, and have <br />not been replaced to date. Some of them may be in a weakened, or deteriorated state, and not <br />able to accommodate the additional water that this may add. or the rate nt which it will be <br />coming. The culverts should all be evaluated as to size, condition, and layout with re.spect to the <br />proposed drainage layout <br />AN EQUAL OPPORTUNITY EMPLOYER
