Page 2 undertaken through excavation and removal followed by replacement of suitable foundation materials. The soils are of a type that is erodible as well as containing peat. The erodibility will be dealt with through a erosion control plan which will be subject for review by both the City of Roseville and the Rice Creek Watershed District. The peat will likely be removed and replaced as previously stated. The ground water depth varies from a minimum of 1.5 feet to 11.5 feet under the existing ground. Sixty soil borings were taken to identify this situation. Bedrock varies from 50 to 100 feet below existing elevations. B. Physical Effects on Waters. The site in its existing condition contains approximately 17.5 acres of brush or grass land which in the after condition would be converted to impervious surface. No wetlands exist on the site at the present time. No major physical alteration of existing dikes, streams, lakes, or other drainage systems will occur on the site. It will not be necessary to appropriate ground or surface water or affect the ground levels of any wells. It is incorporated into the plans that on -site erosion control facilities would be installed and kept in place until the work is completed to protect off -site drainage facilities receiving the flows from the site. The MnDOT pending area located near the I-35W off -ramp and Cleveland Avenue is included as being within the City of Roseville's shoreline management ordinance as a natural environmental conservation area. The proposed project is consistent with the development standards contained in the city's shoreline management ordinance in regard to buildings and parking areas. The most southerly office facility would require a conditional use permit from the city to meet the setback standards. The City of Roseville does not have an official flood insurance map as it has been ruled as not necessary by the federal government. Experience indicates that the MnDOT pond at the extreme south end of the site has had a history of water flowing over Cleveland Avenue to a depth of approximately one-half foot. The project's plans for on -site ponding and storm sewer improvements for each phase of the proposed development are expected to offset any potential increases in flows to this location. The project is in an area that the oity's comprehensive plan had designated as a mixture of industrial, medium density residential, low density residential and business uses. On December 5, 1985, the Planning Commission requested approval of an amendment to the comprehensive plan, so it is in conformance with the project. On December 16, 1985, the council approved the amendment to the comprehensive plan and Metropolitan Council approval of the amendment will soon be requested by the city. It is also consistent with the 1982 Roseville Redevelopment and Tax Increment Plan. C. Water Rqglkty Effects_ Wastewater, Stormwater and Erosion. The project would produce approximately 66,275 gallons per day. This is in addition to approximately 147 gallons per day of off -site sewage which comes to commonly shared facilities. The northern two-thirds of the site plus the off -site areas currently flows to a City of Roseville sanitary sewage lift station on the west side of Cleveland Avenue. This lift
