Q: Trowbridge Park, just west of the Marquette city limits, was platted out in 1910 and by 1915 families had started to buy lots and move there. Because it was outside the city limits, taxes were low and some families bought more than one lot so they could farm. Other people built camps on lots in the community. But there were on-going issues with water and sewage, severe enough that in 1958 one family had eight cases of typhoid. What year were sewer lines finally completed in the township?
A: D. The water lines were completed in 1973 and the sewer lines were completed in 1991.
