ENVIRONMENTAL BOARD MEETING MARCH 28, 2001 species. Asleson assured the Board he would go on site to check for plant associations when the growing season had begun. Trehus asked if he had the actual lines of the conservation easement. Asleson stated that the area was interesting in its biodiversity. Mach explained that they did not want developments so near the water, and used the townhouses on the south side of the road as an example. Asleson noted the structures needed to be 150 ft. from the open water, and that number is increased to 200 ft. in unsewered areas. Chair Lanyon stated if the Environmental Board wanted to make that recommendation it would need to go to the Planning and Zoning Board at that level. Asleson indicated a compacted 600 -ft. buffer does not reduce nutrient loading, unless other alternatives are included such as water treatment train practices. He asked where the water would go. Mr. Goertz explained the water would flow to the front of the houses, and that there was up to 60 ft. of sod in the back of the house. Kukonen asked if it was up to the builder, what type of driveway they could have. Mr. Goertz answered that it would ultimately be up to the builder, and commented he was trying to create the cul -de -sacs without gutters or curbs, so the runoff flows into the sodded yards. He was waiting to hear back from John Powell in regards to this issue. Trehus advised that because the area was considered a high ecological value zone, a 100 -200 ft. buffer was needed around the wetlands, and other boards needed to be aware of this number. Chair Lanyon asked for a formal recommendation, not approval, but support or non - support. Trehus concurred the Board votes on the recommendations because the Council wanted to know the aspects of the proposals which are good or unacceptable. Chair Lanyon reviewed recommendations in addition to staff recommendations included the curb and gutters, re -site the cul -de -sac to change the angle, and the 100 -200 ft. buffers. Asleson mentioned a 50 -ft. buffer was required around isolated wetlands and 100 ft. around lakes. Trehus expressed concern for the land because according to the map, it was a high ecological zone. Asleson agreed and urged an informational sheet be distributed 6
