19. Geologic hazards and soil conditions a. Approximate depth (in feet) to ground water: 0 ft. minimum 12 ft. average to bedrock: 200 ft. minimum 200 ft. average Describe any of the following geologic site hazards to ground water and also identify them on the site map: sinkholes, shallow limestone formations or karst conditions. Describe measures to avoid or minimize environmental problems due to any of these hazards. There are no known geologic site hazards to groundwater within the study area or in close proximity to the proposed site. b. Describe the soils on the site, giving NRCS (SCS) classifications, if known. Discuss soil granularity and potential for groundwater contamination from wastes or chemicals spread or spilled onto the soils. Discuss any mitigation measures to prevent such contamination. Based on information obtained from the Soil Survey of Anoka County, the following soil map units are contained within the project area and shown on Figure 5. Map Symbol Soil Map Name Drainage Class Iw AJD Isanti Fine Sandy Loam, 0 -2% slope Very Poorly Drained LnA Lino Loamy Fine Sand, 0 -4% slope Poorly Drained ZmA Zimmerman Fine Sand, 0 -2% slope Excessively Drained ZmB Zimmerman Fine Sand, 2 -6% slope Excessively Drained ZmC Zimmerman Fine Sand, 6 -12% slope Excessively Drained The combination of excessively drained soils and a relatively high groundwater table creates a substantial potential for groundwater contamination. The site will be connected to municipal sewer and water systems to eliminate two potential sources of contamination. At this time, proposed use of the site does not involve the use or generation of hazardous chemicals. If chemicals are to be stored on site, they will be stored either indoors or in self - contained facilities to eliminate the potential for spills and subsequent groundwater contamination. 20. Solid wastes, hazardous wastes, storage tanks a. Describe types, amounts and compositions of solid or hazardous wastes, including solid animal manure, sludge and ash, produced during construction and operation. Identify method and location of disposal. For projects generating municipal solid waste, indicate if there is a source separation plan; describe how the project will be modified for recycling. If hazardous waste is generated, indicate if there is a hazardous waste minimization plan and routine hazardous waste reduction assessments. There are no known hazardous wastes associated with the proposed development The City does not provide full solid waste collection services for residents and businesses in the community. Residents and businesses contract their solid waste removal needs with independent garbage haulers that are licensed by the City. b. Identify any toxic or hazardous materials to be used or present at the site and identify measures to be used to prevent them from contaminating groundwater. If the use of toxic or hazardous materials will lead to a regulated waste, discharge or emission, discuss any alternatives considered to minimize or eliminate the waste, discharge or emission. Proposed uses of the site include light industrial operations. Generally these types of uses do not produce or handle substantial amounts of hazardous materials. It is possible that some occupants may use or handle hazardous materials as part of their business. Any occupant which utilizes hazardous materials would be required to conform to all existing laws and regulations in place at the time of development.
