Flagstaff flood control costs of $15 million
Coconino County supervisors were briefed on Tuesday about the possible flood control measures needed for the Timberline subdivision that flooded last summer after the Schultz fire denuded the slopes above the alluvial fan based homes.
AZGS geologist Ann Youberg participated in the county review of 6 options presented by engineering firms a couple weeks ago. They ranged from building a massive set of diversion berms that would de facto become regulated dams, to leaving the area as it is but buying out all the homes. The latter option was suggested as being cheaper than building enough flood control structures to protect the properties. Such actions have been taken elsewhere in the state. The larger project proposals have price tags of $30 million or more.
Meanwhile, we received a link to a set of photos of the Schultz fire on Dan Greenspan's blog that we hadn't seen before. [right]
