under Information Sources will help you locate the information
you need. Storm water programs should be designed to address
the specific needs of the community and water resources they
are intended to protect. If you haven't done so already, collect
information on your city's receiving waters and what pollutants
and sources are impacting those waters.You should also know
the various uses of your receiving waters so you can design a
program to protect those uses. Complete a table below for each
