on Indian River Boulevard, and would become L.O.S. "E" at that point." Commissioner Wheeler felt that any time a car crossed 4 lanes of traffic to make a left turn, the L.O.S. was considered "E", and Director Davis explained that it depends on the volume of traffic on the 4 -lane roadway. Right now the volume is in the order of 11,000-12,000 trips per day, and you can interrupt and make a turn movement without lengthy delay. Attorney Collins: "Based on experience with the trips out of the Vista residential area, is an assignment of 10o traffic onto Indian River Boulevard from the shopping center a conservative assignment, or would an assignment of 30% of the trips onto Indian River Boulevard be more accurate?" Director Davis: "In my opinion, 1 feel that 30o is more accurate." Attorney Collins: "Does the 30o assignment show 204 left turns onto Indian River Boulevard from the shopping center?" Director Davis: "I feel that the consultant, Kimley-Horn, is indicating that the storage that is provided by adding a lane in that area would accommodate 204 vehicles per hour, based on DOT standards." Attorney Collins: If there is 204 trips capacity stacking lane, how many trips do the 30o convert into per hour. In other words, if 30o trips out of the shopping center are going out onto Indian River Boulevard, how many trips per hour are turning left onto Indian River Boulevard?" Mr. Bird felt he could answer that question. He stated that there is a total of 396 trips from the site, and 30% of 396 is 118 trips. However, some of those will go north onto Indian River Boulevard and some will go left, so we are looking at a portion of the 118 trips. He explained that Kimley-Horn showed the 204 figure just to show that there is an overkill on storage with the addition of the 4th lane and that it is more than what is needed based on the traffic volumes. 38 APR 51988 BOOK 71 PAGE 468
