Sohrweide, PE, PTOE <br />FATE: August 8, 201.& <br />Gem Lake Hy-Vee..C-Store Traffic Impact Study Review <br />SEH No. GEMLK 145993 Task 7 14.00 <br />�s requested we have reviewed the Gen! Lake HyNe.e C-Store Traffic Impact Study, prepared by Wes.twood.and <br />dated July 27, 2018. <br />ollowing are our comments relative to this study, <br />1. Traffic Counts <br />a. What'date(s) and day(s) were counted? <br />2, Figures <br />a.. It is .difficult Immediately determine in the. figures which.are AM and PM numbers. The bold is not <br />that bold. and some. numbers overlap. Is it correct to assume that the first number closest.to the <br />i arrow is AM? <br />3. Safety <br />a, Crash history.reports that°only three involved vehicles traveling.to:or from Hoffman.. Road." On <br />the crash diagram it appears that there -are four and potentially a fifth depending.on description. <br />j The diagram for.the 9/1112012 crash may be a right turn to Hoffman, since the left through lane <br />I ends just past that location. <br />b.. Several places in the report, state that u-turns which wouldlikely: increase with. restricted access, <br />would "cause. a safety concern", We do not agree that this would he a safety concern, with u- <br />turns not being out of the ordlnary on the TH 61 corridor. <br />On page. 8 of the report, expresses concern on the part of businesses -for u-turns. that would occur <br />from Scheuneman. Road. Figure of the report shows this valurne to be no vehicles in the AM <br />.Peak Hour and 12 vehicles In the. f'M beak Hour. These volumes indicate very little impact, Also <br />{ of note is that CR E east of TH fit does nflt have.a.center median, therefore if u-turns began to <br />` occur, they would.like.ly be prohibited. <br />4. Modeling <br />a. What speed was Used .for GR E? <br />b. Does the.modeling reflect. the following. lane uses of these lntersections? <br />.1. TH 611CR E <br />1. :Southboun.d left turns.predominately from :the left rhost lane. <br />2. Eastbound th ru. movements predominately from the leftmost thru lane. <br />U.
