The south access is very close to the <br />gnahzed intersection. This access will create problems with traffic on the county roads and we would <br />recommend that the site be served with only one access at a location further north o^f the intersection As <br />a ininimum we would suggest that the south access be restricted to only right-turn in 'right-turn out <br />movements^ Left turn movements should only be made at the north accek Hennepin Sty mime <br />engineere should review the site plan to determine the traffic impacts on CSAH 19.
