2. The degree of danger that materials may be swept on to other lands or downstream to the injury of others.
3. The susceptibility of the proposed use to flood damage and the effect of such damage to the owner.
4. The importance of the proposed use to the community.
5. The availability of alternative locations not subject to flooding for the proposed use.
6. The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters expected at the site.
7. Such other factors which are relevant to the purposes of this chapter.
