Ames Construction Land Alteration, 425 Old Crystal Bay Road N. December 9,2005 Page 2 The storm sewer line cannot be installed until the retaining wall is constructed. In order to install the storm sewer line behind the retaining wall, the timeline for construction of the retaining wall has been moved up substantially. The construction of the retaining wall requires the excavation and disposal of 25,000 cubic yards of material. Ames needs a place to dispose of this material to enable the project to move forward. Because the need to dispose of this material was not anticipated prior to the recent decision regarding the location of the storm sewer line, Ames does not have a site for the disposal of the material. The interim land alteration plan has been revised to enable the material excavated for the retaining wall to be placed on the James site. This will not require any trucking on public roadways, because the trucks can go directly fix)m the Highway 12 corridor onto the James property. Staff has worked with Ames to revise the interim land alteration plan to limit the land alteration to the southern portion of the site, and to ensure the fill is placed on the site in conformance with the parameters determined by the Council as part of its review of this site during the Rural Oasis planning }»ocess (See Exhibit C). Specifically, other than a berm along the edge of the property, the fill will not be above the elevation of Old Crystal Bay Road. The grading plan attached has not yet been revised to reflect the discussions held on December 8 regarding limiting the land alteration activity to the southern portion of the site. That plan is expected to be in hand for Monday’s meeting. Limiting the topsoil removal and filling to the south end also avoids drainage impacts to adjacent properties to the north and west, which was the key concern expressed by these neighbors. Ames has provided a number of supportive documents which have been forvmded to the City Engineer for review, including the wetland delineation report (delineation is scheduled to be reviewed on site by MCWD staff on Tuesday); copies of submitted permit applications to MCWD and MPCA; and a Storm Water Pollution Prevention Plan (SWPPP). The City Engineer is reviewing the plan and associated documents to ensure no drainage impacts and determine if there are any engineering issues. He will provide a report at the Council meeting. Rccommcndatioii Subject to the City Engineer ’s report and necessary permits from other agencies, staff is supportive of the Ames request for an interim permit to strip topsoil from the southern portion of the James property, and to fill and grade that portion of the property. CoNMil Actton Requested Motion authorizing staff to issue an interim land alteration permit for topsoil stripping and filling in the southern portion of the James property, subject to the City Engineer ’s review, and the necessary permits from other agencies.
