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
The new post office will have to be built in accordance with a demanding new citywide building code.
