This paper reports the results from linear regression models that estimate the cost of dam removal as a function of the dam’s height and length. The models indicate that, on average, each vertical foot contributes between $22,331 and $30,620 to the cost of removal. These estimates are in line with the only other study we are aware of that estimates cost per foot. Although the models fail to account for potentially important variables, they may be useful for providing rough estimates of the variable portion of dam removal cost.
