There have been a number floods there over the years. I remember a bad one around 1972. My opinion is that over the years, with all of the development and all of the land turned into housing, there is very little to slow down the water that goes into the Patapsco River. All that rain has to go somewhere.
Hi,
You've nailed it, Gil!
Some years back a rapidly developing area in SoCal experienced some serious flooding during one of our uncommonly wet winters. In particular, a seasonal creek, which had not flooded in 150 years of records, overflowed and caused all kinds of damage and commotion. Nobody could understand it, until some rocket surgeon (County planning department or Univ. of Calif.--I forget which) figured out what you just said, that neither red tile roofs, concrete or asphalt absorb much water, and the three in conjunction with each other simply took several square miles worth of runoff and funneled it straight into this little creek, where it ran 5-8 feet higher than ever recorded until the rains subsided.
And we pay these people? :roll:
