Thanks! The Karth Lake Improvement District Board ________________________ 5.2. Maintenance and improvement of Art Larsen Memorial Gardens – Background: Susan has worked with the City and several volunteers to remove weeds from the garden and add over 100 new plants. Watering has required hauling buckets of water the homes of neighbors nearby who volunteered to help. Action: The Board asked Todd to report whether the City sprinklers in Cummings Park reach the garden and whether we could coordinate sprinkling with new plantings/dry spells, etc. 5.2.1. Sprinkler Status and Plans - David Swearingen: David said Jeff Frid would investigate the sprinkler system in the spring and modify it as needed to water the plantings. 5.3. Long Term Strategic Plan Elements: Projects and Funding – Board & Staff 5.3.1. Remediation of BMP #1 Site Background: Todd gave us an update of the status and plans at the last meeting, but we did not have time for questions. Questions for Todd include: 1. Q: On the figure below, do all the yellow lines indicate pipes? Please explain what each node and line represent. A: David: Yes, all the yellow lines are pipes or another water conduit such as a culvert. 2. Q: Show where BMP #1 starts and ends on this photo. A: David: The BMP #1 remediation is not on this map. See schematic below. 3. Q: Are the 2 nodes east of the northmost building a low spot where filtration takes place? A: David: Yes. 4. Q: Please explain the elements of the schematic of the Grading and Utility Plan. Q: David explained it. 5. Q: Does the remediation include any mechanism to catch solids -- like a grit chamber — so they do not get in the lake? A: David: The plan as drawn does not have a grit chamber, but a grit chamber will be included. Action: David will send us an updated schematic with the grit chamber shown. [That schematic was received after the meeting and is attached at the end of these minutes.] 6. Q: Is there any mechanism to capture oil products and other pollution and nutrients that are contained in the runoff from the parking lot and road before they enter the lake? A: David: No filtration is provided. This remediation step only captures grit and moves the water down the hill without causing more erosion. Action: David plans to apply for another grant in the future that will divert the water into a holding pond so it is filtered before it empties into the lake. 7. Q: Board members expressed concern about the likelihood that future construction in Shoreview that is within and near the Karth Lake watershed could add more runoff and nutrients. This could increase the water level and pollution of Karth Lake. Board Members thought the lake levels have varied higher since the townhouses were built east of Lexington Ave. Board Members have observed significant water flow into Karth Lake from the holding pond east of Lexington and Karth Lake. Action: We agreed to ask Kyle Axtell to tell us what controls are in place to prevent an increase in Karth Lake water level and nutrient load caused by new construction in Shoreview.
