April 24, 1978 Engineer Hubbard added that the ground water wells have fluctuated and some are higher now than they were in February 1976. He stated that he felt 4' would be a reasonable margin to work with and that drain tile should be required for anything within 4' to insure that the basements did not have water. He added that if the developer planned on bulding at the 906' elevation, he should plan on putting in drain tile. Administrator Achen stated that in the Sundee report it is recommended that anything within the 4' contour have drain tile, and that anything above the 4' would not be required to be tiled. Engineer Hubbard agreed and added that if there is existing ground water within 4', drain tile should also be required. Councilmember Ziebarth expressed concern with the fluctuation of the water table and added that he would be more comfortable with a wider margin. He also asked why the developer chose to put drain tile in some basements but not others. Mr. Buzzell replied that he was concerned with pocketing water and that he had put drain tile in to be safe.

MSP (Baumgartner Ziebarth) that the minimum elevation of construction shall be 5' above the contour established in the Short, Elliott, Hendrickson report by the hydrologist Jerry Sundee or 5' above the existing ground water table, whichever is higher, and that where authorized by the Inspections Department to construct at an elevation below that for whatever reason, a drain tile system will be required. 4 ayes DEVELOPMENT PROPOSALS SET PUBLIC HEARINGS Administrator Achen stated that public hearings should be set and recommended that the Pleasant Acres hearing be set for May 8, the District 2 storm plan for May 22, and that a feasibility study for the extension of Edgewood Drive from County Road I north to Hillview Road be ordered. He added that hearings would be required for the Mounds View Square Addition, Dailey Knolls Plat, and Silver Lake Road improvements would have to be set at subsequent Council meetings. Official Rose added that the dates could be set but the Council might wish to review the feasibility studies before setting the hearings for Dailey Knolls and Silver Lake Road improvements.
