EXAMINATION OF EXISTING HIGHWAY MAINTENANCE GARAGE LOCATIONS IN TWO STUDY AREAS IN IOWA. FINAL REPORT

An optimum allocation model was employed to examine the existing highway maintenance garage locations in two selected areas in the southeastern and southwestern parts of Iowa. In Study Area No. 1, the examination reveals an annual savings of approximately $12,700 would be achieved if the garage at Columbus Junction were closed while the garage at Nichols is already closed. However, it is noted if the garage at Nichols were re-opened, a greater savings (approximately $18,500 per year) would be achieved by closing the garages at Columbus Junction and Iowa City. It also appears that with the garage at Nichols officially closed, only a small savings (approximately $5,500 per year) is achievable by closing the garage at Iowa City. A further analysis shows that only a minimal savings (approximately $1,800 per year) can be achieved by closing the garage at Nichols. In Study Area No. 2, the examination shows annual savings of approximately $22,700 would be achieved, without unduly increasing dead-end travel time, if garages at Emerson and Shenandoah were closed. It is also noted that relocating the Oakland garage to the intersection of U.S. 59 and Iowa 92 would not result in any significant savings (approximately $400 per year). Recommendations are as follows: (1) Closing the maintenance garage at Nichols should be re-evaluated in light of the findings of this study and other considerations. In particular, the re-opening of the Nichols garage with simultaneous closure of garages at Iowa City and Columbus Junction should be carefully compared with the alternative of closing the garages at Nichols and Columbus Junction. (2) Serious consideration should be given to closing the garages at Emerson and Shenandoah.
