If the project provides for only one mode, the design should not preclude use by the other mode, now or in the future, where appropriate. Some projects provide more benefit than others for the same cost. Realistic cost estimates are needed to determine feasibility. Reasonable costs are consistent with other projects of a similar nature. A reconnaissance design analysis can help determine a cost estimate.
Many grants require a local match.
A funding source needs to be identified, so project construction is not delayed if the project is approved. Many projects, especially separated paths, will require special maintenance to preserve the usefulness of the facility. An agreement or other arrangements may be required to ensure that the bikeway or walkway will be maintained in good condition.
