Flagging Odanah - floodplain seems to now pass through or near old location

[nickrsan]

Silex worth checking - 3 of 8 town parcels contact floodplain. Should we be using minimum/maximum, or mean floodplain distances? Maybe max since we're using a touching measure. If part of the parcel is in town, but part is also out of the floodplain, we want to measure that.

Valmeyer is buggered. Floodplain only on other side of river.

[nickrsan]

Odanah specifically excluded from FIRM maps because on reservation. Going to digitize a polygon, but right way to handle this is probably to use Hazus.

Looks like Valmeyer wasn't missing because of my processing, but because of the NFHL. Appears to be present in paper FIRMs, so will need to digitize it.

[nickrsan]

Valmeyer is mostly digitized, but still needs more to flesh out the county. All towns need to be checked not just for the town touching, but whether or not NFHL covers it completely.

Closing this because a broader ticket (data completeness checks, #54 supercedes it)
