Jenks, I just read this and thought of you, and your ETS-grown project:

"A proposal to use shipping containers to store residents’ personal emergency supplies ... The containers could hold residents’ own supplies, such as backpacks containing enough food, water, medicine and clothing to last several days.... Residents would rent space – probably large enough for a five-gallon bucket -- in the containers for $5 a year ... a 20-foot container – half the size that the committee is considering -- would hold 684 buckets with an aisle for access, or 912 buckets with no aisle. Proceeds from the rent could pay for the containers, buckets and some city staff time within five years."
