# §777.7. Evaluation of impacts.

- (a) The reasonableness of the public expenditure and extent of Federal participation with [title 23](/cfr/23.md), U.S. Code, funds shall be directly related to:
  - (1) The importance of the impacted wetlands and natural habitats;
  - (2) The extent of highway impacts on the wetlands and natural habitats, as determined through an appropriate, interdisciplinary, impact assessment; and
  - (3) Actions necessary to comply with the Clean Water Act, [Section 404](/cfr/23/404.md), the Endangered Species Act of 1973, and other relevant Federal statutes.
- (b) Evaluation of the importance of the impacted wetlands and natural habitats shall consider:
  - (1) Wetland and natural habitat functional capacity;
  - (2) Relative importance of these functions to the total wetland or natural habitat resource of the area;
  - (3) Other factors such as uniqueness, esthetics, or cultural values; and
  - (4) **Input from the appropriate resource management agencies through interagency coordination.**
- (c) A determination of the highway impact should focus on both the short-and long-term affects of the project on wetland or natural habitat functional capacity, consistent with 40 CFR part [1500](/cfr/40/part1500.md), [40](/cfr/40/part40.md) CFR 1502.16, [33 CFR 320.4](/cfr/33/320.4.md), and the FHWA's environmental compliance regulations, found at [23 CFR part 771](/cfr/23/part771.md).
