LSACL commissioned Arup to undertake an economic impact assessment of the Airport and their report will be submitted separately. Their report suggests that, without the growth of passenger services, the net increase in airport-related jobs (including indirect and induced) would be 330 by 2020. The figure of 750 additional jobs could only be achieved if non aviation jobs are attracted by the availability of space rather than by a demand for the particular airport location. The risk with the Low Growth Scenario is that as the number of aircraft and European airlines that can use Southend's existing short runway for commercial services declines, so too do the commercial opportunities for the airport. The risk of business failure for either airport based companies or even the airport increases commensurately, and consideration would need to be given to the 1200 airport based jobs that depend on these companies.
