COMMISSIONER PRESENTATION: Sue Morgan passed out a new and updated storm
' pond/algae article for the Villager and took comments. Ms. Morgan then presented her findings
from research done on storm drain ponds and algae. Included in the presentation were the facts
that only three types of algae cause problems: plankton, filamentous, and musk grass. Duckweed
' is not algae, but, in fact, the smallest herbaceous plant in North America. Storm ponds reach a
maximum depth of 10 feet and a minimum of 4 feet. It takes approximately 15 days for sediment
to settle to the bottom of a pond. Copper sulfate has been recommended by the DNR for treating
' algae in storm ponds.
Mr. Sacchet summarized the Commission's plans as follows:
' • Need an educational component
• Need ordinance and policy formation
• Strongly discourage chemical treatment
' • There should be some form of notification to the neighbors; need a channel to
distribute educational materials
• Form a sub - committee to discuss position. Volunteers included: Sue Morgan,
Charlie Eiler, and Susan Wright. They will draft a policy for review at the next
meeting.
Review of Villager article included the following comments: add the suggestion of residents
getting soil tests done, add the suggestion as item 7 to use biodegradable soap to wash cars.
