Concerned that projects downstream will be developed and assessed to Lake Elmo. Lake Elmo has no problem controlling run-off to Woodbury. --Bohrer - about 1200-1500 acres of Lake Elmo property are in the Cottage Grove Ravine - 40-80 acres are in Oakdale - remaining property is in Woodbury. --Eder - recommended deferring action until April 15 during which time the Attorney.&Administrator will research alternate financing/assessing. --Whittaker - refuted the assumption that because of the size of the pipes from Lake Elmo under 2-94 that the City may be contributing to or causing problems downstream and therefore should -share in assessments. --Bohrer study would show that Lake Elmo intends to limit its run-off to pre -development stage.

These tests are required,with Mn/DOT determined to be the lowest; vender with anestimated cost of $700. Bohrer requested Council authorization to have Mn/DOT do the required testing so that the plans can be completed.
