IML FIGURE 13 - POTENTIAL PIPELINE CONFLICTS Discussions with Don Pennell will lead to design of drainage across the pipeline corridor being set to avoid the pipelines, rather than relocating the pipelines. This will include inlet structures on each side of the corridor, with a bored conduit sized to carry flow beneath all the pipelines. The expected flowline will be below any drainage ditch flowline, but the inlets will have access to allow for periodic de -silting of the structures. 6. Conclusions and Recommendations By following the discussion of the design for each of the items listed for evaluation, the total estimated construction cost for the project is in excess of $3.5 Million. This is far beyond the programmed level of funding. However, the removal of components of the project will help reduce the cost to bring it closer to budget. Therefore, the listing below removes a major item, and removes components of two other items to reduce costs. 6.1. PAVEMENT REHABILITATION The project as described above, but with the removal of the reconstruction of the western portion of Taxiway A is recommended. Also, while desirable but not necessary, the spray Page 132
