and asked whether a street sewer on the southern edge of the KL watershed could redirect water into KL watershed; said the Board should be given a heads-up if there is a watershed change because our residents incur the costs of increased inflows in the form of increased pumping and pump maintenance. David said: Shoreview cannot redirect water into Arden Hills without approval which is unlikely to be granted. Tony asked: does Arden Hills require and Environmental Impact Analysis. Can the KLIDB be included in any EIA if Shoreview develops land the affect the KL watershed? Kyle said: what he could do is plant a review note that says KLIDB should be included in any action; and will look at permit files for the property in 2016. Kyle will send GIS maps to Gary. Renee: can we get any history of development? Kyle will look to see if there is anything. After the meeting Kyle sent an email with a summary of his presentation and comments. Here it is: “I am following up as promised from the 4/13 KLID meeting. I took a couple of screenshots from our GIS mapping system that show the Karth Lake sub watershed boundary and the LiDAR topography of the area. I think these two are representative of the information I discussed and showed during the meeting. The third figure is a close- up of the Shoreview parcel east of Lexington Avenue that was discussed at length during the meeting (4166 Lexington Avenue N). You will see three points identified on this parcel: • 87-066: This is the original RCWD permit for development of the existing building on the site. Stormwater does indeed drain to the south and east, away from Karth Lake. The intended build-out of the rest of the site was envisioned to do the same, although that development has never occurred. • 16-041R: This is the review file I mentioned during the meeting. At that time, a developer was proposing a series of high-density residential buildings (initially, two) beginning in the NE corner of the parcel, presumably expanding west toward Lexington as units filled up and demand increased. That development never materialized. The concept also assumed runoff would drain to the existing stormwater basins to the east, away from Karth Lake. I will note that any future development will likely need to expand upon the existing stormwater treatment. It is highly unlikely that the existing basins (from the 1980's) would meet current stormwater management standards. • 21-092R: This is the "flag" I planted on the site to make any future RCWD permit reviewer aware of KLID's interest in the area. I added a specific note that the primary concern was any additional runoff volume leaving this site and possibly entering Karth Lake, which is landlocked. I referenced the pumping system and that the residents must pay for its operation and upkeep. As discussed during the meeting, I would encourage KLID to communicate with the City of Shoreview regarding any potential for further development of this site. RCWD is not aware of any current proposals.
