<br />d If the project requires disposal of liquid animal manure, describe disposal technique <br />and location and discuss capacity to handle the volume and composition of manure. <br />Identify any improvements necessary, Describe any required setbacks for land <br />disposal systems. <br /> <br />There will be no disposal of liquid animal manure from the proposed development. <br /> <br />19. Geologic hazards and soil conditions <br />a. Approximate depth (in feet) to ground water: Q minimum 10 maximum; to bedrock: <br />unknown minimum unknown maximum <br /> <br />Describe any of the following geologic site hazards to ground water and also <br />identify them on the site map: sinkholes, shallow limestone formations or karst <br />conditions. Describe measures to avoid or minimize environmental problems due to <br />any of these hazards. <br /> <br />Recent soil boring logs indicate that sand is a significant component of soils on the <br />site. Many borings encountered surface layers of sand and subsurface layers with <br />sand lenses. Sand has a fairly high infiltration and percolation rate, which could <br />allow downward movement if hazardous materials are spilled on the soil surface. <br /> <br />There are no abandoned or unused wells on site, All abandoned or unused wells <br />were closed during environmental clean up of the site associated with the 1985 plan. <br /> <br />The potential hazard of ground water contamination would be minimal after site <br />development since work areas will be converted to impervious surface. Remaining <br />areas will be landscaped, with layers of soil and sod added. These actions will <br />significantly reduce the risk of hazardous materials contaminating groundwater. <br /> <br />The proposed uses for the site are business park uses, which include office and hotel <br />uses, These uses do not produce or handle toxic or hazardous materials, <br /> <br />b, Describe the soils on the site, giving NRCS (SCS) classifications, if mown. Discuss <br />soil granularity and potential for groundwater contamination from wastes or <br />chemicals spread or spilled onto the soils. Discuss any mitigation measures to <br />prevent such contamination. <br /> <br />Soils are mapped as a combination of Urban Land Zimmerman Complex, Urban <br />Land, Urban Land Lino Complex, and Isanti Loamy Fine Sand (Figure 7). <br /> <br />Original soil types mapped on Figure 7 (as described above) are no longer present on <br />the site due to the mass grading and filling which has occurred. Currently, soils on <br />the site are most appropriately classified as Urban Land in developed portions and as <br />Udorthents (fill) in most of the undeveloped land. <br /> <br />Profiles, drainage characteristics, and depth to water table indicated for soils mapped <br />on Figure 7 and described in the soil survey are no longer valid due to these <br />described soils alterations. <br /> <br />Environmental Assessment Worksheet <br />Centre Pointe Business Park <br /> <br />Page 15 of 29 <br />
