... 43 4.1 Introduction Case studies were conducted to apply the concepts identified in the economic impact analysis methodology presented in Figure 3-1. The case studies encompass different freight modes, including rail, highway, ports, maritime, and inland waterways, and cover impacts at the local, regional, and national scales.

... 48 Methodologies to estimate the economic Impacts of Disruptions to the Goods Movement System almost $731 million was attributed to commuting time losses, with the rest assigned to business logistics issues. In round figures, the authors attributed costs associated with restrictions on customer access to $272 million ($229 million within the 5-county Southern California region)

... Case Studies 49 Timeframe of Disruption I-5 was closed for 4 consecutive days from December 3 through the morning of December 7 of 2007, with some limited capacity to handle heavier trucks late on December 6th. Beginning in late January, less than 2 months after the Chehalis area flooding closed I-5, the state experienced another major highway system disruption.

... 52 Methodologies to Estimate the Economic Impacts of Disruptions to the Goods Movement System also broke down its economic impact estimates for the trucking industry and freight-dependent sectors within each of the state's seven major geographical regions, noting similar impact across all regions other than the coastal region, where the I-5 closure impacts were noticeably more severe. The study also provides some interesting qualitative business firm specific case study reports.

... Case Studies 53 A September 27, 2002, Report for Congress on the subject starts with, "The tragedy of September 11, 2001, was so sudden and devastating that it may be difficult at this point in time to write dispassionately and objectively about its effects on the U.S. economy" (Makinen 2002)

... 54 Methodologies to estimate the economic Impacts of Disruptions to the Goods Movement System Assessments of the impact of 9/11 on the supply chain conclude that the greatest disruptions to the supply chain appeared to have resulted from the border closures. "The severe tightening of border controls following the September attacks resulted in long waiting times that disrupted the operations of manufacturing companies, especially at the U.S.-Canada border" (OECD 2002)

... Case Studies 55 traffic along pre-9/11 lines. It was noted by port officials that the 2002 West Coast Port Strike had a much greater impact on ports -- in the aftermath of the strike, major shippers adopted a "port diversification" policy.

... Case Studies 57 Step 3: Define Supply Chain Characteristics and Parameters by Flow Type The port shutdown not only affected maritime traffic, but also had a spillover effect with respect to other modes. Truckers were unable to return containers to the port terminals or to pick up new cargo, railroads lost shipping business to and from ports, and air cargo saw a slight increase.

... 58 Methodologies to estimate the economic Impacts of Disruptions to the Goods Movement System Burlington Northern and Santa Fe Railways lost their container business serving the ports (normally 4,000–7,000 units per day) during the shutdown, but claimed that much of that traffic was either shipped before or after the shutdown, resulting in minimal loss overall (Zuckerman 2002)

At the Port of Catoosa, some 50 firms that relied heavily on the waterway for supplies reported losses of some $300,000 a day in revenue when the waterway was closed.

CSX describes the route as a "merchandise corridor" -- predominately carload traffic, with some coal, some intermodal, and some auto traffic.

... Case Studies 67 While the predominant impact was on the rail freight system on a multi-state level, the fire caused disruptions to businesses and surface transportation activities in the Baltimore area. The ITS Program Office report noted that, "The closing of Howard Street and the surrounding area in essence cut Baltimore's central business district in half, closing off east-west traffic flows" (see Figure 4-15)
