I ~ ~LS Ingerson Neighborhood Q&A Pavement Management Meeting (pMP) July 18, 2002; 7:00 p.m. Page 7 of8 Comment: Has there been a recent water quality report completed and what are the numbers? There has not been a report since last December. We will make sure the most recent report will be available on the City's website. The most recent report did say the City's measures were inadequate and attention should be given to that. There have been some improvements but not was anticipated by DNR. Part of that is being addressed with Council and steps are being taken. Comment: Did that most recent report recommend a vortex chamber? It did not get specific in any oue area. This can be an option for future discussion. Comment: Many people on the lake have their own easement which is Fernwood channel. The area association wrote a letter to the Mayor asking him to look at some way to treat the water. Rice Creek Watershed performed a watershed reconnaissance of Lake Josephine which indicated it should be treated. The City of Roseville has been working to clean up their side and nOw Arden Hills must do the same. Comment: It stated on the University of Minnesota website the #1 pollutant is the grass and leaves decomposing bringing forth phosphorous. Any time water is speeded up it is going to bring up the level of phosphorous into the lake. All water tends to get to the lake the same way. If you have run-off it gets to the catch basins and then to lake eventually. This is an opportunity to build a pond to meet NERP goals. By building a pond of a certain size you can expect to catch a larger percentage of pollutants. In general, the past resident consensus was to do minimal work at the Fernwood channel. Comment: If you change the grade so it flows all the way to Hamline why wouldn't you just carry all the water down to Hamline. We did look at that and it is very expensive and uses a very large pipe. The watershed didn't like that option because we were working against the natural flow. The Femwood channel would then become all backwater as well. Comment: Maybe all the water from Carlton only could go to Hamline and that way you could clean the water going into Josephine adequately. That certainly is a possible option which can be explored. From an engineering point of view it can be done. If Rice Creek is okay with it then we can certainly look at it.
