Erosion and Sediment Control Quantities I I I I I I I I I I I I I I I I I I I 1.1 INTRODUCTION The State of Minnesota requires owners and operators of all construction sites disturbing one or more acres of land to apply for and comply with a construction storm water general permit; Minnesota's General Storm Water Permit for Construction Activity (Permit MNRI 0000 1) issued by the Minnesota Pollution Control Agency (MPCA). The goal of this permit is to reduce the amount of polluted storm water runoff that flows into Minnesota's waters. A reduction in pollution occurs when management practices are implemented to prevent and reduce the erosion on construction sites. The Storm Water Pollution Prevention Plan (SWPPP) was prepared to comply with the Permit. The purpose of the SWPPP is to: · identify potential pollutant sources that may affect the quality of discharges associated with construction activity; · identify non-storm water discharges; · design the use and placement of Best Management Practices (BMPs) to effectively prohibit the entry of pollutants from the construction site into the storm drain system during construction. Erosion and sediment source control BMPs must be considered for both active and inactive (previously disturbed) construction areas. BMPs for wind erosion and dust control are also included. · modify the SWPPP as the project progresses and as conditions warrant This SWPPP is prepared specifically for Lakeside 4th Addition in Chanhassen.

Erosion Control Practices 4.1 Temporary Erosion Control Practices Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in storm water runoff. Erosion control BMPs, protect the soil surface by covering and/or binding soil particles. This project will incorporate erosion control measures required by the contract documents, and other measures selected by the Contractor. Implementation and locations of temporary erosion control BMPs are shown on the Grading and Erosion Control Plans in APPENDIX Band/or described in this section: · Limits of grading activity will be field located to preserve existing vegetation where required and when feasible. · Perimeter erosion control fence will be installed prior to any grading activities. · The construction shall be phased to limit exposed soils during grading. Each phase must be restored per the grading and erosion control plans as work is completed. All exposed soils must be stabilized as soon as possible but in no case later than 7days after construction activity has ceased. · Wood fiber blanket will be installed on all slopes greater then 4: 1. · All temporary stockpiles will be surrounded by erosion control fence and temporary seeded per the grading and erosion control plan, if the stockpile is to remain for more then 7 days. · Apply temporary erosion control to remaining active and non-active areas as required by the Permit and the contract documents. Reapply as necessary to maintain effectiveness. I I I I I I I I I I I I I I I I I I I . The wetted perimeter of any temporary or permanent ditch or swale the drains water from the site or diverts water around the site must be stabilized within 200 feet of the property edge or from the point of discharge into any surface water. Stabilization of the last 200 lineal feet must occur within 24 hours after connecting to a surface water. Pipe outlets must be provided with energy dissipation within 24 hours after connection to surface waters. . Control erosion in concentrated flow paths by applying erosion control blankets, erosion control seeding, add ditch checks and lining swales as required in the contract documents. . If dust from the construction activity becomes excessive, appropriate measures including, but not limited to, water trucks and/or calcium chloride applications must be applied. · Home Construction: a. Back-of-Curb BMPs shall be in place and maintained during homebuilding operations. 1. Developer installed silt fence, fiber rolls or established turf must be present at the curb prior to start of construction 2. After backfill, Back-of-Curb BMPs shall be re-established and maintained until final lot stabilization 3. Acceptable forms of Back- of-Curb BMPs include: silt fence, fiber rolls, or wood mulch (local municipalities may limit the type of sediment control that is acceptable) 4.

Storm catch basins can be protected with one or more of the following BMP: Wimco Pans, Lange IPD, Circle H Enterprises Model AEP-Cl, Circle H Enterprises Model AEP-RBHl, prefabricated geotextile inlet protection inserts d. Adjacent wetlands, ponds and areas at fmal stabilization shall be protected with proper BMPs prior to foundation excavation. I I I I I I I I I I I I I I I I I I I 13. If building next to a wetland or pond, silt fence must be in place to protect the wetland or pond prior to construction starting 14. If construction activity is up gradient to a lot or open area at fma1 stabilization, silt fence or fiber rolls are to be installed to protect the stabilized areas e. Streets shall be swept once weekly, except during frozen ground conditions. 15. Street sweeping shall be done weekly 16. Additional street sweeping is at the discretion of the Lead Superintendent 17. Streets must be scraped clean by contractors at the end of the workday if material is tracked onto the street that day f. Vacant inactive lots with exposed soils shall be stabilized within 7 days after construction activity has ceased. 2. Hydro-seeding, crimped mulch or fiber blankets shall be used to stabilize the exposed soils Sufficient erosion control materials will be maintained on-site to allow implementation in conformance with Permit requirements and described in this SWPPP. This includes implementation requirements for active areas and non-active areas. 4.2 Final Stabilization Permanent turf establishment will consist of: · Spread of stockpiled topsoil to a minimum depth of six inches . Smooth topsoil using horizontal tracking to the slope direction. . Seed, fertilize and mulch per the specifications. · Maintain all temporary sediment and erosion control practices until Final Stabilization is established. · Remove all temporary synthetic and structural erosion control within 30 days offma1 stabilization. . Final Stabilization requires the following: 1. Final Stabilization requires that all soil disturbing activities at the site have been completed and all soils must be stabilized by a uniform perennial vegetative cover with a density of 70% over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions. 2. The Permittee(s) must ensure that the permanent storm water treatment system meets all requirements in Part III, C. This includes but is not limited to, a final clean out of temporary or permanent sedimentation basins that are to be used as permanent water quality management basins and final construction or maintenance of infiltration basins. All sediment must be removed from conveyance systems and ditches must be stabilized with permanent cover. 3. Prior to submission of the NOT, all temporary synthetic and structural erosion prevention and sediment control BMPs (such as silt fence) must be removed on the portions of the site for which the Permittee is responsible. BMPs designed to decompose on site (such as some compost logs) may be left in place. 4. For residential construction only: I I I I I I I I I I I I I I I I I I I a. Final stabilization for single-family residential developments has been achieved when turf has been established for the entire lot or turf along with temporary erosion protection (down gradient perimeter control and mulch over exposed soils) for individual lots has been completed and the has been transferred to the new homeowner with a copy of the Sediment and Erosion Control for New Homeowners sheet. b. For multi-family developments, ftnal stabilization has been completed when turfhas been established for the lot. c. Near the completion of the development, all storm ponds will be clean of unstable sediment. d. When the complete development is at Final Stabilization, the Superintendent is to notify the Land Department to submit to the MPCA for a Notice of Termination. 5. Sediment Control Practices Sediment controls are structural measures that are intended to complement and enhance the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water. This project will incorporate sediment control measures required by the contract documents, and other measures selected by the Owner/Developer/Contractor. Sufficient quantities of temporary sediment control materials will be maintained on-site throughout the duration of the project, to allow implementation of temporary sediment controls in the event of predicted rain, and for rapid response to failures or emergencies, in conformance with other Permit requirements and as described in this SWPPP. Implementation and locations of temporary sediment control BMPs are shown on the Grading and Erosion Control Plans in APPENDIX B and/or described in this section: . Rock construction entrance. . Temporary sediment control basins with stabilized outlet . All stockpile material shall be properly contained and protected. . All sediment tracked on to streets shall be removed within 24 hours of detection. 6. Special or Impaired Waters Additional BMP's The project is within one mile of designated impaired and special waters. Special requirements are as follows: 1. All exposed soil areas shall be stabilized within 7 days after construction activity in that portion of the site has temporarily or permanently ceased. 7. Pollution Prevention Measures 7.1 Solid Waste Collected sediment, asphalt and concrete millings, floating debris, paper, plastic, fabric, construction and demolition debris and other wastes must be disposed of properly and must comply with MPCA disposal requirements. Solid Waste Management will be implemented to minimize storm water contact with waste materials and prevent waste discharges. Solid wastes will be loaded directly into trucks for off-site disposal. When on- site storage is necessary, solid wastes will be stored in watertight dumpsters in the general storage area of I I I I I I I ,I I I I I I I I I I I I the Contractors yard. Cement and asphalt rubble will be stockpiled in the general storage area and will be surrounded with sediment controls (i.e., Sandbag Barrier) and covered when necessary. Solid waste, including rubble stockpiles, will be removed and disposed off-site at least bi-weekly. Hazardous wastes will be stored in the shipping containers or covered containment area discussed above for materials storage. Hazardous wastes will be appropriate and clearly marked containers and segregated from other non-waste materials. 7.2 Hazardous Waste Hazardous Materials: Oil, gasoline, paint and any hazardous substances must be properly stored, including secondary containment, to prevent spills, leaks or other discharge. Restricted access to storage areas must be provided to prevent vandalism. Storage and disposal of hazardous waste must be in compliance with MPCA regulations. No hazardous wastes are anticipated to be stored on the site. Several types of vehicles and equipment will be used on-site throughout the project, including motor graders, scrapers, excavators, loaders, paving equipment, rollers, trucks and trailers, backhoes, forklifts, generators, compressors, and traffic control equipment. A paved temporary fueling area will be constructed in the Contractor's yard. All self-propelled vehicles will be fueled off-site or at the temporary fueling area. Fuel trucks, each equipped with absorbent spill clean-up materials, will be used for all on- site fueling, whether at the temporary fueling area or for mobile fueling elsewhere on the site. Drip pans will be used for all mobile fueling. The fueling truck will be will not be parked onsite overnight Drip pans or absorbent pads will be used for all vehicle and equipment maintenance activities that involve grease, oil, solvents, or other vehicle fluids. All vehicle maintenance and mobile fueling operations will be conducted at least 50 feet away from operational inlets and drainage facilities and on a level graded area. 7.3 Truck Washing and Construction Vehicles No vehicle washing or will occur on site. 7.4 Concrete Washout a. Small mortar mixers may washout on the lot if adequate impermeable concrete washout pit is established b. Ready-mix truck and concrete pumps self contained wash out specifications: . Ready-mix truck drivers wash out into a chute bucket Slurry water from bucket is pumped back into mixer drum 7.5 Spill Prevention Plan These procedures and practices are implemented to prevent and control spills in a manner that minimizes or prevents the discharge of spilled material to the drainage system or watercourses. 7.5.1 Vehicle and Equipment Maintenance . If maintenance must occur onsite, use a designated area and a secondary containment, located away from drainage courses, to prevent the runoff of storm water and the runoff of spills. · Regularly inspect onsite vehicles and equipment for leaks and repair immediately . Check incoming vehicles and equipment (including delivery trucks, and employee and subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite. I I I I I I I I I I I I I I I I I I I . Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks when removing or changing fluids. · Place drip pans or absorbent materials under paving equipment when not in use. · Use absorbent materials on small spills rather than hosing down or burying the spill. Remove the absorbent materials promptly and dispose of properly. . Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip pans or other open containers lying around · Oil filters disposed of in trashcans or dumpsters can leak oil and pollute storm water. Place the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before disposal. Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters. · Store cracked batteries in a non-leaking secondary container. Do this with all cracked batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is cracked. Put it into the containment area until you are sure it is not leaking. 7.5.2 Vehicle and Equipment Fueling · If fueling must occur onsite, use designate areas, located away from drainage courses, to prevent the runoff of storm water and the runoff of spills. . Discourage "topping off' of fuel tanks. . Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks. 7.53 Cleanup . Clean up leaks and spills immediately. · Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent material for larger spills. If the spilled material is hazardous, then the used cleanup materials are also hazardous and must be sent to either a certified laundry (rags) or disposed of as hazardous waste. · Never hose down or bury dry material spills. Clean up as much of the material as possible and dispose of properly. 7.54 Notification Minn. Stat. 9115.061, which has been in effect since 1969, describes the duty of people to notify the Minnesota Pollution Control Agency (MPCA) when spills and leaks occur: 115.061 - Duty to Notify and Avoid Water Pollution (a) Except as provided in paragraph (b), it is the duty of every person to notify the agency immediately of the discharge, accidental or otherwise, of any substance or material under its control which, if not recovered, may cause pollution of waters of the state, and the responsible person shall recover as rapidly and thoroughly as possible such substance or material and take immediately such other action as may be reasonably possible to minimize or abate pollution of waters of the state caused thereby. (b) Notification is not required under paragraph (a) for a discharge of five gallons or less of petroleum, as defined in section 115C.02, subdivision 10. This paragraph does not affect the other requirements of paragraph (a). The law provides penalties of up to $10,000 per day for violations. The Minnesota Department of Public Safety, Bureau of Criminal Apprehension, operates a 24-hour service, establishing a one-call system for all state reporting requirements. I I I I I I I I I I I I I I I I I I I Reportable spills should be directed to the Minnesota Duty Officer by calling (651) 649-5451 or (800) 422-0798. The duty officer will record all pertinent information and then make the appropriate notifications to the state agencies. Spills that must be reported: Report spills that may cause pollution; such as spills of toxic, flammable, corrosive and dangerous industrial chemicals. Also report spills of environmentally damaging materials, including fertilizer, coal, animal parts, batteries, etc. Reportable quantities: Minnesota has a reporting threshold of greater than five-gallons for petroleum spills. Spills of any quantity of all other chemicals or materials should be reported. If in doubt, report. 7.6 Sanitary and Septic Waste a. Portable toilets shall be located on site for sanitary waste collection. 1. Sanitary waste will be collected from the portable toilets in a timely manner to avoid overfilling 2.

Inspection and Maintenance Storm Water Pollution Prevention inspections shall be conducted every seven (7) days or within 24 hours after a rainfall event exceeding O.5-inches in 24 hours. The following shall be completed during each inspection: . Record name, date, and time of inspection . Record rainfall amount if greater than O.5-inches . Inspect the site for excess erosion and sedimentation . Inspect the site for debris, trash, and spills . Inspect temporary erosion and sedimentation control devices . Inspect construction entrances for sediment tracking into streets . Inspect areas which have undergone final stabilization at least once per month . Record recommended repairs and modifications to erosion and sedimentation controls . Record recommended changes to the SWPPP · Record repairs and modifications implemented since previous inspections Key areas identified for inspection, in addition to the above include: . Inspect sediment control barriers for excessive sediment . Inspect all flared end sections for excessive sediment . Inspect adjacent streets for sediment, litter, and construction debris The following guidelines shall be used to determine if pollution control devices require maintenance, repair, or replacement: . All silt fences shall be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches 1/3 of the height of the fence. All repairs shall be made within 24 hours of discovery, or as soon as field conditions allow access. · All inlet protection devices shall be cleaned, repaired, or replaced when they become nonfunctional or the sediment in the WIMCO's reach the top ofthe handles. All repairs shall be made within 7 days of discovery, or as soon as field conditions allow access. . All construction site vehicle entrance locations shall be repaired, replaced, or supplemented when they become nonfunctional, filled with sediment, or allow off-site I I sediment tracking onto paved surfaces. All repairs shall be made within 24 hours of discovery, or as soon as field conditions allow access. . All sediment escaping the construction site, observed on adjacent streets or other properties, shall be removed in a manner and at a frequency sufficient to minimize off site impacts. . All excessive sediments and debris observed at flared end sections, in storm water ponds, or drainage ditches and conveyance systems shall be removed within 7 days of discovery, or as soon as field conditions allow access. . All temporary and permanent sedimentation basins shall be drained and the sediment removed when the depth of the sediment collected reaches Yz of the storage volume. All repairs and maintenance shall be completed within 7 days of discovery, or as soon as field conditions allow access. . All infiltration areas shall be inspected to ensure that no sediment from construction activity is reaching the infiltration area. I I I I I I Where parts of the construction site have permanent cover, but work remains on other parts of the site, inspections of the areas with permanent cover may be reduced to once per month. Where construction sites have permanent cover on all exposed soil areas and no construction activity is occurring anywhere on the site, the site must be inspected for a period of twelve (12) months (the inspections may be ceased during frozen ground conditions). Following the twelfth month of permanent cover and no construction activity, inspections may be terminated until construction activity is once again initiated or sooner if notified in writing by the MPCA. Where work has been suspended due to frozen ground conditions, the required inspections and maintenance schedule must begin within 24 hours after runoff occurs at the site or prior to resuming construction, whichever comes first I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I APPENDIX A APPLICATION FOR GENERAL STORMWATER PERMIT FOR CONSTRUCTION ACTIVITY I I I I I I I I I I I I I I I I I I I Permit No: MN RIOOOOl Complete your application onlinel Minnesota Pollution Control Agency Application for General Stormwater Permit for Construction Activity (MN R 100001 ) National Pollutant Discharge Elimination System I State Disposal System (NPDES/SDS) Please submit to: Minnesota Pollution Control Agency Construction Stormwater Permit Program 520 Lafayette Road North, St. Paul, MN 55155- 4194 PLEASE READ: This form is for new permit applications only.

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, orenhance 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 (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app? agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contactl state_offices/). 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 Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-Iandscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the I I I I I I I I I I I 5 I I I Custom Soil Resource Report I individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil- landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

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 ofthe 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 for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. I I I I 10 I I I Custom Soil Resource Report I 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 mayor 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 the soils or miscellaneous areas in a mapped area are not uniform. An area can be I I I I I I I I I I I I I I I I 11 I I Custom Soil Resource Report I 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.
