Flood Concerns for Laveen?

Here's the deal; I'm probably being paranoid about this, I know..... I worry about Laveen's preparedness for the amount of flooding that could occur this week. Yes, we have the LACC (Laveen Area Conveyance Channel) and other flood retention measures in place, but what about the amount of water that our soil and flood retention basins accumulated already this week; and what about potential bottlenecks on street drainage systems or potentially defective retention measures (which we have already seen here during past storms) among all the other things that could go wrong?

Remember, most of Laveen sits on relatively low ground, and within the typical floodplain of the Salt River, not to mention the Tres Rios confluence just west of us. This is why our county and city officials took the initiative to complete the LACC project and others like it in recent history, as Laveen's population has boomed. Just ask any long-time resident to hear some interesting stories of past flooding.

Further, we may or may not experience unprecedented levels of rainfall in the next 48 hours, combined with rising river levels due to rapid snow melt in the high country.  And I have not been able to find much specific advice for our community, which is a little frustrating....  After all, the storm a couple of weeks ago brought the gutter run-off above the sidewalk in front of my house, and last year I recall watching our water retention basin nearly fill up from a less severe storm.

So to ease all our minds, I offer the following resources:

• WEATHER.GOV/PHOENIX 
  

• Local news coverage about the potentially unprecedented rain and flooding: Channel 3 video.
• Where to pick up free sandbags from the City of Phoenix, if needed: City of PHX site.
• What to do with the sandbags, if you decide you need them: eHow article.
  
• Information about the LACC and other "big" measures to stop flooding: Image and details.
• Info from Maricopa County Flood Control District: MCFCD site.
• Arizona's Flood Warning and Drought Monitoring: AFWDS site.
  
• Historic flood info: USGS website.
• FEMA's flood preparedness advice: FEMA site.

***Bonus recommendation in case there are no sandbags at the free pick-up locations referenced above: Try Home Depot or Lowe's.  If that fails (like finding anything else in Laveen at the moment that we all need it, i.e. propane cylinders on July 4th), then I bet you could justify borrowing some sand from a nearby playground and returning it after the flood recedes.  And by the way, medium trash bags work at least as well as the big burlap ones; you just need more of them.

Please feel free to pass along this information to anyone who you think may need it, or feel free to keep it around as a resource for the next hundred or so years, in anticipation of an eventual 100-year flood (it's not really like nature is on a schedule.... here's a definition of a 100-year flood).  In the likely event that this information is totally irrelevant, then I simply request that you understand how much I love to geek out on information and preparedness.
