Therefore, no environmental impact statement will be requir- <br />ed. The MPCA's comments eXpressed concern for on-site septic systems. They <br />indicated that soil borings indicate mottling at depths of two to three feet. Soil <br />borings completed by the developer do not show mottling; however, as we previously <br />stated it appears that Lots 7-9, Block 8 will require minimal filling to meet the <br />Class I land r.equirement for on-site sewage disposal systems. We also concur with <br />the MPCA that percolation rates should be obtained for adequate design of the <br />drainfields. <br /> <br />Comments ~n regards to permits for discharging storm water into the Mississippi <br />River have been received from the Corps of Engineers and the DNR. The Corps of <br />Engineers stated that no permit would be required provided no work is done below <br />the ordinary high water mark. The DNR stated that a permit would be required for <br />discharge into the river. <br /> <br />Comments from the MN/DOT recommended that the Iguana street N.W. access unto - <br />T.H. 10 be eliminated, no left turn access at Alpaca-Street be allowed and right <br />turn lanes at Llama Street, Armstrong Boulevard, and Alpaca Street be constructed. <br />Entrance permits would have to be issued by MN/DOT prior to construction. MN/DOT <br />also indicated that the noise levels along T.H. 10 exceeded state standards for <br />residential development. <br /> <br />keith caswell jr. ~J darrell schneider ~J richard sha <br /> <br /> <br />
