When multiple alternatives use Section 4(f) property and the evaluation of avoidance alternatives concludes that there is no feasible and prudent avoidance alternative, then FHWA may approve, from the remaining alternatives that use Section 4(f) property, only the alternative that causes the least overall harm in light of the preservation purpose of the statute. 23 CFR 774.3(c) includes a list of factors to consider in making this determination of least overall harm. These factors include the ability to mitigate adverse impacts to Section 4(f) property; the relative severity of remaining harm, after mitigation, to Section 4(f) property; the views of the officials with jurisdiction; and the relative significance of each Section 4(f) property. Other factors include the degree to which alternatives meet the project purpose and need, substantial differences in cost, and impacts to other resources (i.e. non Section 4(f) resources).
