You just went over budget by like 200 million dollars.
Library: With a population of some 30,000 and a proposed budget of $5,200,000, that's $173 per capita, not too shabby, when the average for its population size is about $45.
Education Facility: Reasonably priced at $64 million
Observatory: About $150 per sf as an estimate from an online source. (We'll say around 18,000 feet)
That's 5,200,000+2,700,000+64,000,000
That equals $71,900,000
With 28,100,000 left to spend on payment for employees.
