3 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments ( nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center ( offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist ( cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: Carver County, Minnesota Survey Area Data: Version 11, Sep 16, 2014 Soil Survey Area: Hennepin County, Minnesota Survey Area Data: Version 10, Sep 16, 2014 Your area of interest (AOI) includes more than one soil survey area. These survey areas may have been mapped at different scales, with a different land use in mind, at different times, or at different levels of detail. This may result in map unit symbols, soil properties, and interpretations that do not completely agree across soil survey area boundaries. Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Mar 16, 2012 Apr 26, 2012 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident. 8

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas 10

12 for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of 11

13 the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12

62 Soil Information for All Uses Soil Properties and Qualities The Soil Properties and Qualities section includes various soil properties and qualities displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Erosion Factors Soil Erosion Factors are soil properties and interpretations used in evaluating the soil for potential erosion. Example soil erosion factors can include K factor for the whole soil or on a rock free basis, T factor, wind erodibility group and wind erodibility index. K Factor, Whole Soil Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. 61

These survey areas may have been mapped at different scales, with a different land use in mind, at different times, or at different levels of detail. This may result in map unit symbols, soil properties, and interpretations that do not completely agree across soil survey area boundaries. Soil map units are labeled (as space allows) for map scales 1:50,000 or larger.

67 Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from longduration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas.

Soil Survey Area: Carver County, Minnesota Survey Area Data: Version 11, Sep 16, 2014 Soil Survey Area: Hennepin County, Minnesota Survey Area Data: Version 10, Sep 16, 2014 Your area of interest (AOI) includes more than one soil survey area. These survey areas may have been mapped at different scales, with a different land use in mind, at different times, or at different levels of detail. This may result in map unit symbols, soil properties, and interpretations that do not completely agree across soil survey area boundaries. Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Mar 16, 2012 Apr 26, 2012 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident. 68

74 Minnesota Department of Transportation Best Management Practices (BMP) for Concrete Washout May 2009, v5 The NPDES permit requires that concrete washout be managed on all construction projects. This document is Mn/DOT s interpretation of MPCA s guidance on concrete washout dated February 2009, and describes recommended best management practices for concrete washout. As improvements in technology occur for managing liquid and solid concrete washout materials, the department will amend this guidance document. Example SWPPP amendment indicating change in location of the concrete truck washout area to reflect the needs of contractor activities, signed and dated by the Erosion Control Supervisor, Project Engineer, or person delegated by the Project Owner. Moved here on October 8, 2008, Dwayne Stenlund Mn/DOT Guidance: The NPDES construction permit requires concrete washout management (Part IV.F.4) on every project that uses concrete and concrete products, with SWPPP amendments (Part III.A.5 & Part III.A.7) as necessary to prevent the discharge of concrete liquids and uncured solids from making contact with soils unless in defined containment Best Management Practices (Part V.C & MS4 Permit). Accidental Discharge. If concrete washout makes accidental contact with soils or discharges to waters of the state, state law requires notifying (Minn R Subp 6) the State duty Officer and immediately stop further discharge, remove discharge materials and restore the site to the pre-disturbance condition. Designated Area. The NPDES permit requires that designated concrete washout areas be posted with a sign or spray painted in a conspicuous manner, and inspected as often as necessary to function without discharge. Unless shown, the concrete washout location must be amended in the SWPPP. Special Location Restriction. Washout BMP must be sited more than 200 feet from a DNR public or permit listed Special Water unless robust, redundant best practice protection measures are installed and amended into the SWPPP. The Department reserves the right to indicate in the plans and final details where or where not concrete washout may occur. The following options are recommended as best management practices for handling concrete truck, pump, mixer, chute, hand tools, concrete testing equipment and wheel barrow washout: Concrete Truck Spill kit system. Option A: Lined Trap Option B: Berm Trap Option C: Dumpster Option D: Chute Washout Systems Option E: Concrete Truck & Pumper Option F: Small Volume Systems Spill Response Program: The contractor must have on hand the following items capable of capturing, containing or treating accidental discharge of concrete materials on ground and surface waters: 1. dry washed sand or wood slash mulch that can be used to temporarily solidify liquid concrete washout fluids to facilitate emergency pickup, and 2. Citric acid, dry ice or CO2 compressed gas cylinder (CO2 Sparging) to ph neutralize overflowing traps, berms, dumpsters or other emergency cementitious discharge due to weather or under-capacity trap containment conditions. 1.

Office of Environmental Services Excess and slump test solids placed on plastic until hardened. Contractor may consider installing wire or rebar hook for later pickup removal to crusher or recycling stockpile. Discharge prevention pallet lined with disposable plastic for testing of concrete and washout of tools by Inspectors. Pallet may be made to accommodate skidsteer forks for quick pickup and discharge to defined washout trap areas until liquid evaporates and solids harden. 1

75 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option A: Lined Trap System. A Lined Trap system is excavated in an area with storm water overflow protection and can consist of either a (1) plastic sheeting for all soil types that infiltrate or (2) constructed clay liner or other suitable zero infiltrating soil (Hydraulic Soil Group D). The goal is to retain the liquids until evaporation, CO2 neutralization/settling or pump extraction. A maximum of 0.5 cu yd of cured material can be buried in trap area. Slope less than maximum angle of repose for soil type, typically less than 1:2. Areas with Clay soil that allow storage until evaporation of liquids Conc Washout sign Plastic Liner with posted sign or spray painted notice for washout. Option A, Type 2. Compacted clay or Hydraulic Soils Group D Liner for low infiltration soils. Size of excavated and compacted trap must be commensurate with washout requirements for daily construction activities. Maintenance must be sufficient to prevent overflows due to excess washout, trackout and storm water. The contractor may washout concrete slurries behind poured walls as long as there is no connection to the soil below nor drain-tiled, and 100 percent of material remains contained until evaporation or extraction. No concrete washout may occur if dewatering is or may be required to complete the fill of abutment or footing. Spray Paint Conc Washout on inside poured wall containment area Option A, Type 1. Plastic liner for sandy soil, well head protections area, and critical soil shear area with side slope wall failure above MPCA/DNR Listed Special, or Impaired Waters. Trap size must be appropriate to expected washout volumes and allow suitable time for evaporation, or sufficient capacity for pump extraction. Sides of plastic liner can be held in place with any suitable material including sand, sand bags, rock, metal, wood logs, etc. The Type 1 Traps must be routinely maintained, and replaced as necessary to perform. 2

76 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option B: Berm Trap System. A Berm Trap System may consist of raised walls constructed from wood or wood slash (3882 Type 5 Mulch Material), straw bales, Compost Filter Logs, sand bags, soil, lined concrete barriers, or any suitable strength materials to contain concrete washout liquids and solids until evaporation, curing, or extraction and final removal. No material can be left in place once operations are completed for that area. High cohesive, low infiltration soil berm Concrete washout tote Superduty washout berm Sealed or plastic lined wood washout box Slash mulch filter ring on low infiltration soils Mixing sand berm with plastic liner 2x10 plastic and geotextile box, with 2x4 cleats for front loader pickup and movement Granular berm and plastic liner 3

77 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option C: Dumpster System. A dumpster washout system is any commercial or retrofitted leak-proof dumpster capable of holding liquid and solid concrete washout materials until final treatment and disposal. There are commercial companies available to manage and treat all liquid wastes and recycle all solids. Prevent comingling of other solid wastes with concrete washout materials. Various concrete liquid and solid dumpster systems sized to store all materials until liquid evaporates or vacuum removed and treated by commercial operators. 4

78 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option D: Chute Washout System Two commercial types known include (1) a portable truck mounted pump recovery system, and (2) portable truck mounted pull behind wash tank. A locally manufactured system includes a portable truck mounted plastic trough and reinforced insulated wash box with sealed transport lid. All devices appear capable of containing all concrete liquids and solids, or possess the ability to separate the liquids from the aggregate. At the request of the ready mix operator, the clean washed aggregate may be left in suitable grade areas as determined by the Project Engineer or may be reused as concrete aggregate once processed to comply with Mn/DOT Specifications. At this time, all similar chute washout systems appear equal in ultimate performance goal of leaving no trace of concrete washout residues. Due to the nature of the liquid waste recovery system, there are no restrictions on where the operator may washout the chutes, tools, test equipment, and any portion of the truck that directly drains into to the filter apparatus. A washout sign is not required for chute washout systems. Mn/ DOT concrete inspectors are allowed to deposit tool wash water into the filter bucket system at the discretion of the concrete producer. The contractor is advised not to wash-off truck parts and equipment that does not flow back into the chute system unless performed in designated equipment wash-off areas indicated in the SWPPP or SWPPP amendments. All liquid and solid materials are recovered in filter bucket with vacuum pumping Chute funnel installed onto chute section, prior to lowering chute funnel port to tank opening. Chute Washout System, mounted on metal carriage. Wash tank with slotted filter bucket installed in tank port. Plastic wash trough mounted with rebar hooks to chute, capable of containing rinse wash water and Final rinsing of aggregate. Gravity Drain tube for decanting liquid waste from tank into drum, secured during wash tank filling. Approximately 3 rinse cycles are necessary to adequately clean truck chute, tools, and funnel. 5

79 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option E: Concrete Truck & Pumper Certain operations involving pumper trucks that require priming and end flush cleaning will require special consideration of washout management. Empty concrete truck tank discharge is the process of total containment during high volume preparation and final cleaning of boom pipes and hoses. Final hopper and pump motor cleaning can use Options A through C, front loader bucket, or other Project Engineer accepted plan, and as amended in the SWPPP. Depending on concrete pumper location (ie. well head protection area, sand soils, etc.), concrete perimeter control using super duty barrier and liner, sand, sand bags and plastic or plywood liners may be required to prevent discharge to ground and surface waters during pump hopper loading. If liquid or solid material spills to the soil surface, remove at a frequency to prevent loss to ground or surface waters of the state, and clean by removal of contaminated soil areas to trap areas amended to the SWPPP. Pumper grout slurry discharge form box Plastic liner with 2x4 wood perimeter containment system during concrete transfer operations to pumper truck. Priming or washing out of pumper truck into empty concrete truck for total containment of washout slurry. Concrete Slurry Perimeter control using super duty barrier, aggregate filter toe, and slash mulch filter berms of pumper loading area Final remnant of pumper hopper washout into designated and signed washout trap. 6

80 Minnesota Department of Transportation BMP for Concrete Washout May 2009, v5 Option F: Small Volume Concrete shaping, forming, and inspection operations involving concrete test equipment, tools, and other small items including trowels, forms, wheelbarrows, boots, and gloves that require washout and/or cleaning will require special consideration of washout management. All items must be cleaned or washed in a manner consistent with the requirements described in this guidance document such that liquids and solids from the cleaning operations do not enter ground or surface waters of the state. This can be accomplished by washing items by any method described in this guidance document, or other Project Engineer accepted plan, and as amended in the SWPPP. Less than 0.5 gallons of liquid wash waste may be disposed on the grade. If wash liquid or solid material spills to the soil surface, remove at a frequency to prevent loss to ground or surface waters of the state, and clean by removal of contaminated soil areas to concrete washout trap areas and as amended to the SWPPP. Slump and concrete test equipment waste temporarily stored on plastic sheet until contractor removes at the end of each day. Small quantity concrete wash water into bermed plastic lined trap Traditional designated washout areas can be used for rinse water until evaporation. Small amounts less than 0.5 gallons may be disposed of on the grade if all material remains in the profile or evaporates prior to the next anticipated storm event. Sand may be used to absorb liquid wastes for later transport to the designated washout area. Contractor created pallet for small quantity concrete tool testing wash water containment. Excess liquids transported to designated washout trap as often as necessary to remain functional for the inspection process. Small quantity wash water placed on grade where equipment washoff has been designated in the SWPPP, in areas to receive permanent pavements. Temporary rinse buckets used during testing operations, with liquids transported back into the ready mix truck to batch plant Concrete bucket washout and solids management placed in contractor developed containment box, maintained each day of ready mix operations. 7
