proposed project is comparable in size and surroundings to the existing La Habra Contractor's <br />Warehouse, and is expected to generate approximately the same number of peak hour trips. <br />FOURTH STREET GAP ANALYSIS <br />Measurements of the gaps in through traffic along Fourth Street at Santa Fe Street in Santa Ana <br />were conducted during the AM and PM peak periods on a Monday in January 2007 (included in the <br />appendix), and have been updated with traffic information conducted on August 11, 2011. Gaps of five <br />seconds or more in both directions of traffic were recorded. Left buns into the site from westbound <br />Fourth Street will require a gap of at least fora- seconds in the eastbound traffic to safely cross traffic and <br />enter the site. Left turns out of the site will require approximately seven and one-half seconds to cross <br />both directions of traffic; however, the existence of a two-way left-turn. lane on Fourth Street enables <br />outbound left-turn traffic to complete the turn in two steps (i.e., the vehicle can cross eastbound traffic <br />and wait in the median until an adequate gap in westbound traffic develops). <br />Table 2 summarizes the number of gaps in both directions that are available on Fourth Street at <br />the project site. As this table shows, there were 90 gaps of ten seconds or more in both directions of <br />traffic during the AM peak hour. Assuming that 50 percent of project traffic is distributed to the east and <br />50 percent to the west, there were at least 90 gaps of sufficient duration to accommodate 24 left-turn <br />vehicles (13 trips inbound from east of the site and 11 trips outbound to west of the site) during the AM <br />peak hour. Similarly, there were at least 54 gaps to accommodate 23 left turn vehicles (11 inbound from <br />the east and 13 outbound to the west) during the PM peak hour. Sufficient gaps of adequate length are <br />available on Fourth Street to allow the project traffic to enter and exit the site via a left turn. <br />Santa Ana HD Supply Repair and Remodel Site 6 Austin-Foust Associates, Inc. <br />Traffic and Parking Analysis Update 1217001rpt.doc <br />31A-26
