The General Permit authorizes stormwater discharges to the surface waters of New York State from construction related activities. The project involves soil disturbance of less than 0.5-acres of land and is required to provide a basic SWPPP per the City of Saratoga Springs requirements. As such, no additional stormwater controls are required per NYSDEC standards. This SWPPP describes the erosion and sediment control practices and, where required, the post-construction stormwater management practices that will be used and/or constructed to reduce the pollutants in stormwater discharges. This SWPPP also identifies potential sources of pollution which may be reasonably expected to affect the quality of stormwater discharges. b) Construction Stormwater Team As required by Part III.A.7 of the GP-0-25-001, the Owner/Operator must identify the contractor(s) and subcontractor(s) responsible for installing, constructing, repairing, replacing, inspecting and maintaining the erosion and sediment control practices included in the SWPPP; and the contractor(s) and subcontractor(s) that will be responsible for constructing the post-construction stormwater management practices included in the SWPPP. At least one (1) person from each of the contractors and subcontractors shall be identified as responsible for implementation of the SWPPP and will be known as the Trained Contractor. The Trained Contractor(s) shall be on site daily when soil disturbance activities are being performed. The Trained Contractor(s) who will be engaged in construction activities at the site are responsible for completing the Contractor Certification Form included in the Appendix prior to construction. c) Design Stormwater Team As required by Part III.A.1&4 of the GP-0-25-001, the Owner/Operator must prepare a SWPPP that documents the selection, design, installation, implementation and maintenance of the control measures and practices that will be used to meet the design requirements outlined in the General Permit. Furthermore, SWPPP’s that require the post-construction stormwater management practice component shall be prepared by a Qualified Professional as defined in the General Permit. The Owner/Operator and Qualified Professional have been identified as the following: Name Address Responsibility Dempsey Development 54 Minot Street, Dorchester, MA 02122 Developer Bohler Engineering 17 Computer Drive West Albany, NY 12205 Qualified Professional 5 BE Project #: NYB250046 2) SITE EVALUATION, ASSESSMENT AND PLANNING a) Project/Site Information (Part III.B.1.c.i) Site Name Proposed Mixed Use Redevelopment Address 33-35 Caroline Street City, State, Zip Code City of Saratoga Springs, NY 12866 County Saratoga County Type of Construction: ☐Residential ☐Commercial ☐Industrial ☒Other _Mixed Use Size of Property ±0.23 acres Total Area Expected to be Disturbed ±0.35 acres Maximum Area to be Disturbed at Any One Time: ±0.35 acres b) Site Location Map/Construction Drawings (Part III.B.1.c.ii) The following drawings are included in this report and are bound under separate cover:  Site Survey – Existing condition for the parcel including all required existing information (watercourses, topography, vegetation, utilities, property boundaries, etc.)  Site Plan – Comprehensive plan of all proposed improvements and limits of disturbance.  Grading and Drainage Plan – Plan illustrates existing and proposed slopes, proposed stormwater quantity and quality mitigation measures and limits of disturbance.  Utility Plan – Plan includes detailed design information for the installation of all proposed utilities resulting in the disturbance of soil for this project.  Erosion and Sediment Control Plan – Erosion and sediment control measures to be in place and inspected, prior to commencement of construction. The proposed measures were designed in accordance with the New York Guidelines for Urban Erosion and Sediment Control. Proposed measures include inlet protection, silt fence and/or silt sock, temporary stone outlet sediment traps, stabilized construction entrance and construction sequencing.  Erosion and Sediment Control Details – Plan contains all notes, details and construction sequencing necessary for the construction of the erosion control practices as shown on the Erosion and Sediment Control Plan.  Landscaping Plan – Included is all proposed landscaping for the project.  Construction Details – Included are all details associated with the post-construction stormwater management system. c) Stormwater Discharges The table below identifies all discharge points for stormwater leaving the project site. 6 BE Project #: NYB250046 Point of Discharge Name of State receiving water Is the receiving water on 303d list? If yes, limiting pollutant Design Point 1 Trib to Lake Lonely Yes Fecal Coliforms, Dissolved Oxygen, Phosphorus d) AA or AA-s Classified Watersheds (Part I.A.8.b) The project does not propose to disturb more than one acre of existing non-impervious area on steep slopes within a watershed of Surface of the State classified as AA or AA-s. e) Consideration of Future Physical Risks Due to Climate Change (Part III.A.2) Increasing Temperature: The subject project is proposing to minimize the impact of land alterations by reducing impervious areas where possible. For example, the project proposes to minimize drive aisle widths, minimize parking space size, and minimize the number of parking spaces to what is required to support the proposed use. Correspondingly, the project will maximize available greenspace and landscaping. These techniques both aid to decrease the adsorption of radiant heat from increasing temperatures. Increasing Precipitation, Variability, and Severity of Storm Events: The subject project proposes a new stormwater management system that has been sized to collect and transport stormwater to a downstream discharge point, while meeting or exceeding the requirements set forth for stormwater quality and quantity control measures. The storm pipe network will adequately transport stormwater, while accounting for both cost and efficiency of the project. The industry standard calculation and simulation methods were used to determine pipe sizing. Rising Sea Level: The subject project is not located near, nor directly discharges to, low-lying costal areas which are at elevated risks of inundation during high tides. Shifting Ecology: Due to the uncertainty of the ever-changing ecosystem, direct results & outcomes are uncertain. However, the subject project is proposing to incorporate the latest technologies in stormwater management practices that have been tested and approved by the NYSDEC. 3) EROSION AND SEDIMENT CONTROLS a) Soils Description (Part III.B.1.c.iii) Data supplied by the USDA Natural Resources Conservation Service (NRCS) indicates that site soils are primarily classified as: USDA Soil Symbol Hydrologic Group (HSG) Texture Character % within disturbed area DeA A Deerfield Loamy Fine Sand Moderately well drained 100% The USDA NRCS Soil Survey is included in the appendix of this report. 7 BE Project #: NYB250046 b) Construction Phasing Plan (Part III.B.1.c.iv) Construction sequencing, limits of clearing and grading, utility and infrastructure installation, and all other associated activities resulting in soil disturbance are detailed on the Erosion and Sediment Control, Grading and Drainage and Utility Plans. A recommended Construction Sequence has been included on the Erosion and Sediment Control Notes & Details sheet. Part I.E.6 of the SPDES General Permit for Stormwater Discharges from Construction Activity, requires written authorization from the New York State Department of Environmental Conservation (NYSDEC) prior to disturbing more than 5 AC of soil. c) Minimum Soil & Erosion Control Measures (Part III.B.1.c.v) The Soil and Erosion Control measures that are proposed to be implemented for this site are shown and detailed in the Site Development Plans (part III.B.1.c.vi). All practices are to be installed per requirements outlined in the NYSDEC Standards and Specifications for Erosion and Sediment Control (Blue Book). The project design proposes no deviations from these standards. All practices shall be installed per the timeline outlined in the Construction Sequence and shall remain functional until the contributing areas have achieved 80% stabilization. The dimensions, material specifications, installation details and operation and maintenance requirements are included on the Soil Erosion & Sediment Control Notes & Details Sheet included in the Site Development Plans (Part III.B.1.c.vii). d) Soil Stabilization Plan (Part III.B.1.c.vi) All temporary and permanent soil stabilization practices to be implemented at the subject Project are outlined in the Erosion & Sediment Control Plan included in the Site Development Plans. It is the responsibility of the General Contractor to identify any areas that are not adequately stabilized and provide adequate stabilization practices to address. As a guideline, any temporary or permanent slopes over 3:1 shall be stabilized using slope stabilization fabric installed per the manufacturer’s guidelines. Any open soil that is not to be disturbed within 14 days shall be seeded or mulched. These practices shall remain operational until 80% establishment has been achieved. e) Maintenance Inspection Schedule (Part III.B.1.c.viii) Maintenance of the proposed erosion and sediment control practices are detailed on the Erosion and Sediment Control Plan. Included in this report are the SWPPP Observation and Operations and Maintenance Checklists. The owner/operator is ultimately responsible for inspection and maintenance during construction. Stabilization must be achieved prior to removal of temporary erosion and sediment control devices. Operations and maintenance of this facility is the responsibility of the owner/operator. A designated representative shall conduct bi-annual inspections and keep a log of results and mitigation measures taken. This log shall be made available to the authority having jurisdiction upon their request. Maintenance shall depend mainly on inspection observations and all records should be sent to the Stormwater Program Manager as they are performed. Any deficiencies in the facility shall be corrected immediately upon discovery. Sediment removal shall occur as needed but at minimum twice yearly (if applicable). Cleaning of structures shall include the removal, and proper disposal, of all sand and debris from sumps. A qualified hauler, familiar in the proper disposal of 8 BE Project #: NYB250046 waste shall dispose of sediment. Inspection forms and/or checklists in addition to maintenance procedures have been provided for use as part of this document. f) Pollution Prevention Measures (Part III.B.1.c.ix) The following activities are anticipated during construction and could have the potential to generate pollutants. All such activities are to be conducted in accordance with all applicable General Permit requirements and in accordance with industry-standard best management practices. An inventory of possible pollutants and their associated pollution prevention measure is listed below.  Construction waste will be disposed in on-site construction dumpsters immediately. The dumpsters shall be located such that any stormwater runoff will be directed to a sediment trap.  Any materials or chemicals considered to be hazardous shall be covered or stored in construction trailers to ensure no discharge to stormwater will occur.  A concrete washout will be installed prior to any concrete being poured onsite. The washout will meet or exceed the requirements outlined in the Blue Book.  Any spills that occur must be reported to the below contacts: Contact Name Phone Number NYSDEC Spills Hotline NYSDEC 1-800-457-7362 City of Saratoga Springs James Salaway, PE (City Engineer) 1-518-587-3550 The proposed stormwater management system has been designed to minimize the offsite environmental impacts of potential pollutants from the proposed project. These pollutants can include sediments, nutrients, organic carbons, trace metals, chlorides, and bacteria. Sources of these pollutants include atmospheric deposits, leaking vehicle fluids, and windblown debris from adjacent areas. These pollutants are commonly found in urban stormwater runoff and their effects can be mitigated by the proper implementation of approved stormwater management practices. g) Stormwater Discharges Associated with Non-Construction Activity (Part III.B.1.c.xi) Construction support activities located beyond the construction project area are not to be covered under this SWPPP and the Construction General Permit. h) Deviation from Blue Book Standards (Part III.B.1.c.xii) None of the proposed Soil Erosion & Sediment Control practices are proposed to deviate from the NYSDEC technical standards as outlined in the Blue Book. Any changes to the approved Soil Erosion & Sediment Control Plan that are made in the field during construction shall be documented and the Engineer of Record shall be informed. 9 BE Project #: NYB250046 4) POST CONSTRUCTION STORMWATER MANAGEMENT (a) Introduction The applicant, Dempsey Development, is proposing to develop a 0.23-acre property located at 33- 35 Caroline Street, in the City of Saratoga Springs, Saratoga County, New York. The project will include construction of ±9,315 SF building along with associated parking, access drives, stormwater management, landscaping, and utilities. The proposed features are shown on the latest Site Plan Documents prepared by Bohler Engineering NY, PLLC. This report will briefly discuss the proposed development and provide a detailed analysis of the existing and proposed site conditions and the proposed stormwater management system. Hydraulic calculations included in this report were generated for the 1-, 10- and 100-year storm events utilizing the SCS TR-20 and HydroCad Stormwater modeling software. The following type II, 24-hour SCS rainfall distribution was applied to the calculations: Rainfall Event Depth (inches) 1-Year 2.24 10-Year 3.73 100-Year 6.25 Source: Cornell University data, “Extreme Precipitation in New York and New England”. (b) Existing Conditions The project site is primarily developed entirely with existing impervious areas with moderate topography. The existing project site has been divided into Two (2) Watershed areas for analysis purposes. Watershed ground covers, flow paths, and design points are depicted in the Existing Conditions Watershed Areas Summary Table Below. Watershed Ground Cover Flow Path Discharge Point E-1 Impervious Sheet flows to shallow concentrated, eventual discharge to catch basin in the right of way DP-1 (Existing catch basin) E-2 Impervious Sheet flows to shallow concentrated, eventual discharge to catch basin in the right of way DP-2 (Existing catch basin) The existing watershed areas, discharge points, and topography are illustrated on the Existing Watershed Map included in the appendix of this report. 10 BE Project #: NYB250046 (c) Proposed Conditions The proposed development is designed to mimic the existing drainage patterns and reduce the discharge flow rate from the pre-developed to post-developed conditions. The proposed project site has been divided into Two (2) Watershed area for analysis purposes. Ground covers, flow paths, and design points associated with proposed flows are depicted in the Proposed Conditions Watershed Areas Summary Table Below. Watershed Ground Cover Flow Path Discharge Point P-1 Impervious Sheet flows to shallow concentrated, eventual discharge to catch basin in the right of way DP-1 (Existing catch basin) P-2 Impervious, Green space Sheet flows to shallow concentrated, eventual discharge to catch basin in the right of way DP-2 (Existing catch basin) The proposed watershed areas, topography and flow paths are illustrated on the Proposed Watershed Plan, included in the appendix of this report. (d) Stormwater Calculations As proposed, the redevelopment project will decrease impervious coverage while implementing the new building, parking, utilities, and associated appurtenances. The redevelopment project proposes to disturb approximately ±15,300 SF (±0.35-acres) of existing impervious area and decrease the total impervious coverage to ±15,260 (a net impervious decrease of ±40 SF). As such no further stormwater management practices are required per NYSDEC standards. The table below shows the total required and proposed water quality and runoff reduction volumes for the overall project. Treatment Required (CF) Provided (CF) Percent Achieved (%) Requirement Met? (Y/N) Water Quality WQv 0 0 N/A Y Runoff Reduction RRv / RRv min 0 0 N/A Y The proposed stormwater management system serves to mitigate the impact of the development. During major storm events, post-development peak rates are expected to be reduced from pre- development peak rates, as shown on the discharge quantity table(s) below. 11 BE Project #: NYB250046 Rainfall Event Design Point 1 Existing (cfs) Proposed (cfs) % Reduction 1-year 0.17 0.16 5.88 10-year 0.29 0.28 3.45 100-year 0.48 0.48 0 The existing and proposed stormwater models, depicting peak flow rates for pre- and post- development conditions are included within the appendix portion of this report. (e) Operations & Maintenance Maintenance of the proposed erosion and sediment control practices are detailed on the Erosion and Sediment Control Plan. Included within the appendix portion of this report are Construction Inspection and Operations and Maintenance Checklists. The operator is ultimately responsible for inspection and maintenance during construction. Stabilization must be achieved prior to removal of temporary erosion and sediment control practices. A designated representative from the above-mentioned party shall conduct bi-annual inspections and keep a log of results and mitigation measures taken. This log shall be made available to the municipality at their request. Maintenance shall depend mainly on inspection observations. Any deficiencies in the facility shall be corrected immediately upon discovery. Sediment removal shall occur as needed but at minimum twice yearly (if applicable). Cleaning of structures shall include the removal, and proper disposal, of all sand and debris from sumps. A qualified hauler, familiar in the proper disposal of waste shall dispose of sediment.

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 (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? 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.

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-landscape 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 5 scientists classified and named the soils in the survey area, they compared the 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 Custom Soil Resource Report 6 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 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 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. Custom Soil Resource Report 11 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 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.
