TRAFFIC ANALYSIS Access to the site is provided by two driveways on East Fourth Street-one of which is for a truck dock. The main entrance will be via the easternmost entrance which is situated on the south side of Fourth Street between Tenninal Street and Santa Fe Avenue. The second driveway (i.e. the westerly most one) is restricted to a truck dock for delivery of supplies to the site by large tracker-trailer vehicles. This driveway is not used by the general public. Fourth Street is striped with four travel lanes and a two-way left turn median. No parking is permitted on Fourth Street which means visibility entering and exiting these access points is good. Access to the main parking lot is also provided by a driveway near the cul- de-sac end. The two-way left turn lane on Fourth Street serves both of the site's two entrances as well as Santa Fe Avenue. With three locations to enter the site from a left turn on Fourth Street (all of which include a left turn lane for stopping and waiting for a gap) no significant traffic queues are expected for the site. The existing La Habra Contractor's Warehouse case study included driveway counts of vehicles entering and exiting the property during the AM and PM peak periods on a Monday in January 2007 (actual data is included in the appendix). These counts show that the existing Contractor's Warehouse generates a modest 48 trips during the AM peak hour (26 trips inbound and 22 trips outbound) and 46 trips during the PM peak hour (21 trips inbound and 25 trips outbound). The proposed project is comparable in size and surroundings to the existing La Habra Contractor's Warehouse, and is expected to generate approximately the same number of peak hour trips. FOURTH STREET GAP ANALYSIS Measurements of the gaps in through traffic along Fourth Street at Santa Fe Street in Santa Ana were conducted during the AM and PM peak periods on a Monday in January 2007 (included in the appendix). Gaps of five seconds or more in both directions of traffic were recorded. Left turns into the site from westbound Fourth Street will require a gap of at least four seconds in the eastbound traffic to safely cross traffic and enter the site. Left turns out ofthe site will require approximately seven and one- half seconds to cross both directions of traffic; however, the existence of a two-way left-turn lane on Fourth Street enables outbound left-turn traffic to complete the turn in two steps (i.e., the vehicle can cross eastbound traffic and wait in the median until an adequate gap in westbound traffic develops).
