§ 9.9 Analysis and reevaluation of practicable alternatives. ( a ) *Purpose.* ( 1 ) This section expands upon the directives set out in § 9.6 of this part in order to clarify and emphasize the requirements to avoid floodplains and wetlands unless there is no practicable alternative. ( 2 ) Step 3 is a preliminary determination as to whether the floodplain is the only practicable location for the action. It is a preliminary determination because it comes early in the decision-making process when the Agency has a limited amount of information. If it is clear that there is a practicable alternative, or the floodplain or wetland is itself not a practicable location, FEMA shall then act on that basis. Provided that the location outside the floodplain or wetland does not indirectly impact floodplains or wetlands or support development therein (see § 9.10), the remaining analysis set out by this regulation is not required. If such location does indirectly impact floodplains or wetlands or support development therein, the remaining analysis set out by this regulation is required. If the preliminary determination is to act in the floodplain, FEMA shall gather the additional information required under Steps 4 and 5 and then reevaluate all the data to determine if the floodplain or wetland is the only practicable alternative. ( b ) *Analysis of practicable alternatives.* The Agency shall identify and evaluate practicable alternatives to carrying out a proposed action in floodplains or wetlands, including: ( 1 ) Alternative sites outside the floodplain or wetland; ( 2 ) Alternative actions which serve essentially the same purpose as the proposed action, but which have less potential to affect or be affected by the floodplain or wetlands. In developing the alternative actions, the Agency shall use, where possible, natural systems, ecosystem processes, and nature-based approaches; and ( 3 ) *No action.* The floodplain and wetland site itself must be a practicable location in light of the factors set out in this section. ( c ) The Agency shall analyze the following factors in determining the practicability of the alternatives set out in paragraph (b) of this section: ( 1 ) Natural environment (including, but not limited to topography, habitat, hazards, when applicable); ( 2 ) Social concerns (including, but not limited to aesthetics, historical and cultural values, land patterns, when applicable); ( 3 ) Economic aspects (including, but not limited to costs of space, technology, construction, services, relocation, when applicable); ( 4 ) Legal constraints (including, but not limited to deeds and leases, when applicable); and ( 5 ) Agency authorities. ( 1 ) The Agency shall not locate the proposed action in the floodplain as established by § 9.7(c) or in a wetland if a practicable alternative exists outside the floodplain or wetland. ( 2 ) If no practicable alternative exists outside the floodplain or wetland, in order to carry out the action the floodplain or wetland must itself be a practicable location in light of the review required in this section. ( e ) *Reevaluation of alternatives.* Upon determination of the impact of the proposed action to or within the floodplain or wetland and of what measures are necessary to comply with the requirement to minimize harm to and within floodplains and wetlands (§ 9.11), FEMA shall: ( 1 ) Determine whether: ( i ) The action is still practicable at a floodplain or wetland site, considering the flood risk and the ensuing disruption of natural values; ( ii ) The floodplain or wetland site is the only practicable alternative; ( iii ) The scope of the action can be limited to increase the practicability of previously rejected non-floodplain or wetland sites and alternative actions; and ( iv ) Harm to or within the floodplain can be minimized using all practicable means. ( 2 ) Take no action in a floodplain unless the importance of the floodplain site clearly outweighs the requirements to: ( i ) Avoid direct or indirect support of floodplain development; ( ii ) Reduce the risk of flood loss; ( iii ) Minimize the impact of floods on human safety, health and welfare; and ( iv ) Restore and preserve floodplain values. ( 3 ) Take no action in a wetland unless the importance of the wetland site clearly outweighs the requirements to: ( i ) Avoid the destruction or modification of the wetlands; ( ii ) Avoid direct or indirect support of new construction in wetlands; ( iii ) Minimize the destruction, loss or degradation of wetlands; and ( iv ) Preserve and enhance the natural and beneficial values of wetlands. ( 4 ) In carrying out this balancing process, give the factors in paragraphs (e)(2) and (3) of this section great weight. ( 5 ) Choose the “no action” alternative where there are no practicable alternative actions or sites and where the floodplain or wetland is not itself a practicable alternative. In making the assessment of whether a floodplain or wetland location is itself a practicable alternative, the practicability of the floodplain or wetland location shall be balanced against the practicability of not carrying out the action at all. That is, even if there is no practicable alternative outside of the floodplain or wetland, the floodplain or wetland itself must be a practicable location in order for the action to be carried out there. To be a practicable location, the importance of carrying out the action must clearly outweigh the requirements of the Orders listed in paragraphs (e)(2) and (e)(3) of this section. Unless the importance of carrying out the action clearly outweighs those requirements, the “no action” alternative shall be selected.
