ENVIRONMENTAL BOARD MEETINGMARCH 26, 2003 <br />2 APPROVED MINUTES <br />Donlin stated she was concerned that the trees would be used for infiltration. <br />Asleson responded that drought and not too much water usually killed trees. He <br />indicated it was one more tool to manage the water volumes. <br />Mr. Goertz noted that there would be a permanent proposed conservation <br />easement. He indicated that the Resource Inventory had been completed. <br />Grundhofer questioned the number of feet that would be protected along the <br />power line to where the trees started. Mr. Goertz answered that there was a 70- <br />foot conservation easement in the power easement. Custom grading would leave <br />an additional 40 feet behind each house and 50 feet between each house would be <br />conservation easement. The easement would inhibit owners from cutting their <br />trees. <br />Chair Kukonen inquired how the infiltration would affect the conservation <br />easements in the north. Mr. Goertz responded that it had been mowed. <br />Donlin asked for confirmation that the light green area was where oaks were <br />present. Mr. Goertz affirmed there was a stand of oaks at that location. <br />Donlin inquired about the 9 foot change in elevation. Mr. Goertz answered that <br />due to the high water table, the houses would have full basements at the same <br />height. <br />Chair Kukonen noted that the developer was preserving at least 25%, in addition, <br />he liked the proposed buffering. He was encouraged to see many of the things the <br />Board recommended in the past in this project. <br />Mr. Goertz stated that the timeline would be to build next year, and grade this <br />year. <br />Chair Kukonen noted that the density was lower. <br />Mr. Goertz indicated that the infiltration basins were part of the existing <br />conditions and would take care of the backyard water. The water in front of the <br />houses would go over the curb. It would take a 20-year event before it left the <br />site. He stated that there was no pond in the groundwater. It was above the water <br />table so the woods would be kept. <br />Grundhofer noted that in the northeast, low shrubs such as significant clumps of <br />aspen and dogwoods would be filled. Mr. Goertz answered that the existing <br />wetland would not be touched. <br />Asleson inquired about the public access area. Mr. Goertz responded that the <br />drainage and utility easement would be 5 feet on either side and would not have <br />many maintenance issues because of the sandy soil. He indicated that he would
