Brownlea' s post office must be replaced with a larger one  The present one cannot be expanded  Land near the present location in the center of town is more expensive than land on the outskirts of town
Since the cost of acquiring a site is a significant part of the total construction cost, the post office clearly could be built more cheaply on the outskirts of town
If the new post office is built near the center of town, disruptions to city traffic would have to be minimized by taking such steps as doing some construction work in stages at night and on weekends.
