KLOAI\ 411aeha 1PP4 quo am MEMORANDUM TO: Andrew Goodman GMX Real Estate, LLC FROM: Brendan May Consultant Luay R. Aboona, PE $ Principal DATE: December 19,2017 SUBJECT: Proposed Retail Development Traffic Impact Summary Decatur, Illinois This memorandum is prepared in response to the City of Decatur's request to allocate funds for potential roadway improvements to accommodate future traffic increases as a result of the proposed retail development to be located in the southwest quadrant of the intersection of Water Street with Ash Avenue. Based on the traffic study prepared by KLOA, Inc. dated November 14, 2017,the concerns that have been raised by the City are not warranted based on the following: « As can be seen from the results of the capacity analyses, the intersection of Water Street with Ash Avenue overall and all of the approaches are projected to operate at level of service (LOS) D or better during the peak hours with increases in delay of less than four seconds. It should be noted that this projected condition includes, in addition to the traffic that will be generated by the proposed development, a five percent increase in background growth which translates to approximately 180 additional trips during the evening peak hour. o The proposed development-generated traffic is only projected to increase the volume of traffic traversing the intersection of Water Street with Ash Avenue by two percent or less during the peak hours. • The results of the capacity analyses indicate that the Huston Hills Road and proposed access drive approaches at Ash Avenue are projected to operate at LOS C or better during the peak hours. « In conjunction with the proposed development, the stacking area provided for the eastbound lanes on the west leg of Ash Avenue at its intersection with Water Street will be increased from 95 feet to 285 feet.Additionally,a westbound left-turn lane will be provided on Ash Avenue at the proposed access drive that will provide 125 feet of storage. The results of the capacity analyses show that the 95th percentile queues for the eastbound approach will be approximately 200 feet and the 95th percentile queues for the westbound left-turns will be one to two vehicles (25 to 50 feet)only.
