  • The Wet Well pump in the side pond that would connect to a small water feature which would start sucking the mucky water into one corner which could then be removed by maintenance crews once a month (if not more) and that, plus adding more aquatic plants throughout the stream to absorb nutrients, may be enough to get things stabilized again.  If not, then at a later date we can swap in a more expensive Biofilter into the Wet Well / BioFalls system which is designed to absorb even more nutrients.  If that still does not do it, we can add a second Biofilter to the top side pond.
  • The location of the Wet Well and BioFalls fountain is the side pond across from the glacial water feature (the pond just before the final lower big pond).  Initial discussions were to possibly install the Biofilter in the uppermost pond.  However, further analysis determined the water flow would be too fast in that location for the Biofilter to be efficient, and the side ponds would be the best fit.  The lower side pond across from the glacial feature was selected due to its proximity to an existing electrical power source (which makes instillation cheaper) as well as the favorable existing terrain layout.  If the one Biofilter in this location isn’t enough, a second one could be installed in the upper side pond across from the agrarian fountain.
  • We are also investigating applying for a grant from Dane County for free plants from their native plants program which could be planted along the banks and in the stream to help absorb algae feeding nutrients and reduce runoff.  While this means waiting until next year to start the aquatic planting process, it does allow for the possibility for even more cost savings.
  • The neighborhood is utilizing the services of two new stream management companies, “GreenScapes” and “Advanced Aquatic Specialists.”

Budget Impact:

The current stream improvement plan calls for improvements to be spread out over the next 3 to 5 years, allowing for costs to be absorbed within the existing HOA budget.  There are no plans to raise HOA dues to cover these improvements at this time.
