Lake City Tunnel Study
Empirical Measurement
Statistical analysis, including backwards stepwise multiple regression analysis and t-tests of population means, of transactions of homes situated along the Lake City Tunnel. It was found that any negative impact of a deep sewer easement on the value of a residential property is immeasurably small. Also, an owner survey found that the tunnel cannot be heard or felt at the ground level during normal operation, and that the presence of the deep sewer tunnel easement is not perceived by buyers as important enough to be significantly prioritized in the course of a sale of a house property.
