Frequently Asked Questions (FAQ)

Question:
How much material was removed from debris basins during the 2009/2010 storm
season?

ANSWER:
The District removed close to 1.3 million cubic yards of material from its debris retention
facilities. (One cubic yard is roughly the size of a typical washing machine. The Rose Bowl in
Pasadena would hold about 400,000 cubic yards.) According to storm season projections, the
District will need to dispose of an estimated 1.2 million cubic yards of material each storm
season for the next 3-5 years, as watersheds affected by the recent wildfires recover.
