<br />. <br /> <br />. <br /> <br />ditch/culvert system and ultimately ends up at this point. So <br />you can see that all of this area ultimately drains to here. <br /> <br />MR. POPOVICH: <br />could you describe <br />sense. <br /> <br />Don, when you say "he;r-en or "this point", <br />it? Later on in the record it won't make any <br /> <br />MR. CHRISTOFFERSEN: Okay. To a point on the west side of <br />Lexington Avenue, just north of Red FOX Road. Sorry about that. <br />Drainage is then conducted along the west side of Lexington <br />Avenue through an open ditch/culvert system to Grey FOX Road <br />where it continues westerly to a 42 inch culvert on Grey Fox Road <br />into an open ditch, through some culvert systems and in an open <br />ditch system to State Trunk Highway 51, under State Trunk High- <br />way 51 into Bethel Ditch. Shoreview has a storm sewer along <br />Island Lake Road from this point, from about mid-point on the <br />drawing as you see it to Lexington Avenue. Ramsey County, in the <br />past few years, has constructed storm sewer along Lexington <br />Avenue between the Soo Line Railroad and Grey Fox Road in this <br />loca tion-. <br /> <br />The proposed plan consists of utilizing detention basins, <br />B-1, A-2, A-l, A-3, B-2 and D-l. The plan as proposed is to <br />construct an outlet structure on B-1, under County Road F <br />construction. There is an existing pipe that was constructed <br />for an outletting of B-1 so that County Road F would not have to <br />be open cut in the event the storm sewer system came through. <br />It is proposed then to connect to that southerly end of that <br />outlet to B-1, construct a storm sewer south to detention basin <br />B-2, which would end up in detention basin B-2, and then ulti- <br />mately go through an outlet structure at B-2 into another storm <br />sewer system. On the easterly portion of the Land O'Lakes site, <br />it is proposed to connect with the existing system on County <br />Road F, construct a storm sewer southerly to detention basin <br />A-3. This is a necessity because the existing pipe was planned <br />for storm sewers and the ditch line is actually about mid-point <br />of the pipe flow line. It is also planned to propose the pur- <br />chase from Land O'Lakes of the westerly portion of the detention <br />basin that they constructed, lower the easterly portion of this <br />basin to allow for the appropriate storm water storage in the <br />detention basin and construct the outlet pipe from the southerly <br />end of detention basin A-3 to Interstate 694. <br /> <br />As an aside, the Minnesota Department of Transportation <br />is also interested in this problem because they are experiencing <br />some flooding. The Minnesota Department of Transportation has <br />agreed, if Shoreview purchases an easement within this area, . <br />has agreed to construct, operate and maintain detention basin <br />D-l and construct a storm sewer from Lexington Avenue along the <br />north side of the interstate freeway to a point south of deten- <br />tion basin B-2 and then construct a crossing into detention <br />basin C-l. They plan to enlarge this detention basin. To do <br />this type of construction, all of the drainage, as I explained <br />before, in Arden Hills, all of the drainage north of Gramsie <br />Road will drain, as indicated before, to detention basin A-3 <br />and B-2, picked up in the Minnesota Department of Highways storm <br />sewer and discharged into detention basin C-l.
