Pro_j ect Description The project location is the Saratoga Honda located at 3402 Route 9 (South BroadWay) in Saratoga Springs. The proj ect proposes an expansion of vehicle parking via porous asphalt, a building addition, and some changes to the drive aisles to accommodate the building addition. II. Existin�Water and Sanitar_y Sewer Utilities Municipal water service to the site is provided from a municipal 10-inch water main located along Crescent Avenue. There is water service to the existing building via a 4-inch water line that connects into the municipal main along Crescent Avenue, approximately 180' from the intersection with South Broadway. Municipal sewer service to the site is located from a manhole to southeast of the intersection of Crescent Avenue and South Broadway. From the sewer manhole a 6" PVC gravity sewer service is provided to the existing building. III. Pro_j ected Water and Wastewater Flows This proj ect does not propose any changes to existing water and waste water flows. IV. Proposed Water and Wastewater Utilities Proposed Water Utilities There is a 6" DIP water line at the southwest corner of the existing Saratoga Honda building footprint. The new building addition will impact this line since its location is within the foot print of the proposed addition. The proj ect proposes rerouting the 6" DIP water line around the outside of the proposed addition and reconnecting it to the previous connection point at the Saratoga Honda building. There will no additional water flows as a result of this relocation. Proposed Wastewater Utilities There are no new wastewater utilities proposed. .��_?

The objective of this plan is to comply with the New York Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction Activities, Permit No. GP- 0-20-001 requirements. Any material conflicts between this plan and the site plans, specification or instructions, must be brought to the attention of the design professional. The project may have other permits and it is the responsibility of the owner and contractor to know and understand all permits. The operator will be issued a bill from New York State for a one hundred and ten dollar ($110.00) annual fee for the open GP-0-20-001 permit. The operator will also be billed by New York State for a one time one hundred and ten dollar ($110.00) per acre fee for the proposed disturbed soil area listed in the NOI, and finally a one time six hundred and seventy five ($675.00) per acre fee for the proposed increased impervious area listed in the NOI. The operator is responsible to maintain onsite in a secure location that is accessible during normal working hours to an individual performing a compliance inspection, the fol lowi ng i nformation: ✓ the Notice of Intent (NOI), ✓ the NYS Department of Environmental Conservation NOI Acknowledgement Letter, ✓ the SWPPP, ✓ a copy of the General Permit (included in the SWPPP), ✓ MS4 SWPPP Acceptance Form (where applicable), and ✓ All inspection reports. All post-construction stormwater management facilities must be inspected annually by a qualified professional, a report prepared and submitted to the City Engineer documenting the inspections as well as the maintenance activities that were completed during the prior year. Technical standards are detailed in the "New York State Standards and Specifications for Sediment and Erosion and Sediment Control (November 2016)", as well as illustrated on the Construction Drawings included in Appendix C. The design of post- construction stormwater control practices follow the guidance provided by "New York State Stormwater Management Design Manual." � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C.

Page 2 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 3.0 SITE ASSESSMENT, EVALUATION AND PLANNING 3.1 Project Location The site is located to the southeast of the intersection of Route 9 and Crescent Avenue, located in the City of Saratoga Springs, NY. See Appendix C for a general site location map. 3.2 Pre-Development Conditions The existing surface cover for the site is a mixture of developed and undeveloped land. The northern portion of the property is a car dealership with associated paved parking lot. The southern portion of the property is undeveloped woods and grass. 3.3 Project Type This project is a combination of new construction and redevelopment. The project has been designed in accordance with Chapter 4 of the NYSDEC Stormwater Management Design Manual, and NYSDEC's General Permit (GP-0-20-001) for construction activities. 3.4 Project Scope The Project includes a building expansion (8,000 square feet) of the car dealership, a new drive aisle, and a new porous pavement parking lot. The remainder of the proposed site improvements includes construction of site lighting and landscaping, and stormwater controls. The total Project soil disturbance will be 1.5 acres. The Project will increase the site impervious area by 0.43 acres for a total of 4.38 acres. 3.5 Historic Preservation Determination/Environmental Assessment A letter from NYS Office of Parks, Recreation and H istoric Preservation (OPRH P) dated April 9, 2014, indicates that the project will have no adverse impact on resources in or eligible for inclusion in the State and National Register of Historic Places (see Appendix G). The Project is within an area that will impact on any listed, proposed to be listed, threatened or endangered species, or a critical habitat. As part of the previous facility expansion site survey was completed by The LA Group's staff biologist and determined that the presence of the listed endangered species were not present onsite. Therefore this project will have no negative impact on listed, proposed to be listed, threatened or endangered species, or a critical habitat. The site survey report can be found in Appendix G. � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C.

Permanent Stabilization Practices (including vegetative practices) ✓ Seed and mulch all disturbed areas. Slopes that are 3:1 or steeper should receive a Rolled Erosion Control Product (RECP), sodding, and or hydro- seeding a homogenous mixture of wood fiber mulch with tackifying agent. Refer to Construction Drawings attached in Appendix C for detailed information on each practice. 4.2 Erosion and Sediment Control Drawings � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C. Page 4 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 Erosion and Sediment Control practices are shown on Construction Drawings included in Appendix C. 4.3 Construction Phasing Plan and Sequence of Operations ✓ Temporary structural erosion controls will be installed prior to earthwork as per the attached plans. ✓ Areas to be undisturbed for more than 14 days will be temporarily stabilized by seeding. ✓ Disturbed areas will be reseeded and mulched immediately after final contours are re-established and no more than 14 days after the completion of construction at that site. ✓ Temporary erosion control devices will not be removed until the area served is stabilized by the growth of vegetation and the area is certified as being stabilized by the Erosion Control Superintendent. Reference Construction Activities Sheet Start � Stop Number Sequence must include major items such as, but not limited to, clearing and grubbing, excavation and grading, utility and infrastructure installation and any other activity resulting in soil disturbance.

Page 5 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 4.4 Erosion and Sediment Control Practice Maintenance ✓ Silt fence — maintenance shall be performed as needed and material removed when "bulges" develop in the silt fence. ✓ Stabilized construction entrance — entrance shall be maintained in a condition which shall prevent tracking. This may require periodic top dressing with additional aggregate. All sediment tracked onto or spilled on public rights of way shall be removed immediately. When necessary, wheels must be cleaned to remove sediment prior to entrance on public rights of way. When washing is required, it shall be done in an area stabilized with aggregate and wash water shall be directed away from streams or wetlands preferably to a broad grassed area or a stormwater pond. ✓ Rock outlet protection — once a riprap outlet has been installed, the maintenance needs are very low. It should be inspected after high flows for evidence of scour beneath the riprap. Repair should be immediate. ✓ Replace top-soil, mulch and seed where seeding has been disturbed. 4.5 Erosion and Sediment Control Inspection ■ It is recommended that a rain gage be installed at the site. ■ A qualified inspector shall conduct an assessment of the site prior to the commencement of construction and certify in an inspection report that the appropriate erosion and sediment controls described in the SWPPP and required by GP-0-20-001 have been adequately installed to ensure overall preparedness of the site for commencement of construction. ■ This qualified inspector must be a Licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, or someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided they have received 4 hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity. After receiving the initial training, the qualified inspector shall receive 4 hours of training every 3 years. ■ The day-to-day erosion control activities on the site will be monitored by the construction manager. The qualified inspector (as defined by the NYS DEC SPDES regulations) and his crews will make at least one inspection every seven (7) days of erosion control devices, and non-stabilized areas during construction. A maintenance inspection report will be completed by the qualified inspector after each inspection. The report form to be completed by the inspector is attached in Appendix D. Reports should be compiled and maintained on-site in the SWPPP 3-ring binder. � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C. Page 6 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 ■ All measures will be maintained in good working order; if repair is necessary, it will be initiated within 24 hours of report. The qualified inspector shall take photographs of any needed repairs and also photograph when the repairs are completed. These photographs will be time and date stamped and attached to the weekly inspection report. ■ Seeded and planted areas will be inspected for bare spots, washouts, and healthy growth. If necessary, spot reseeding or sodding will be implemented. ■ A trained contractor will be an employee from the contracting company responsible for the implementation of the SWPPP. This person will be onsite when any soil disturbing activities are being conducted. The trained contractor must have received 4 hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity. After receiving the initial training, the qualified inspector shall receive 4 hours of training every 3 years. This trained contractor cannot conduct the regular SWPPP compliance inspections unless they meet the qualified inspector qualifications. 4.6 Contractor Sequence Form The operator shall prepare a summary of construction status using the Construction Sequence Form (included in Appendix E) once every month. Significant deviations to the sequence and reasons for those deviations (i.e. weather, subcontractor availability, etc.), shall be noted by the contractor. The schedule shall be used to record the dates for initiation of construction, implementation of erosion control measures, stabilization, etc. A copy of this table will be maintained at the construction site and updated. 5.0 POST CO N STRU CTI O N STO RMWATE R MANAG E M E NT PRACTICES 5.1 Stormwater Management Controls This project will impact existing stormwater management practices (SMPs). There are currently (5) SMPs on site, and this project will impact (3) of them: Ex- SMP-1, Ex-SMP-2, and Ex-SMP-3. Ex-SMP-3 is not being resized to treat additional area but will be impacted by the work. It is currently a pocket pond which drains to a stormwater disposal area. It will be redesigned and flows will instead be directed to an infiltration basin. The proposed Post Construction Stormwater Management controls on this project are listed below: • Pocket Pond (Ex-SMP-1) � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C. Page 7 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 • Porous Pavement (Ex-SMP-2) • Infiltration Basin (SMP-3) 5.2 Green Infrastructure Practices/Runoff Reduction Techniques The proposed Green I nfrastructure practices or Standard Management practices with Runoff Reduction capabilities on this project are listed below: ✓ Veg etated Swa I e ✓ Porous Pavement ✓ I nfi Itration Basi n The provided runoff reduction volume is 0.116 ac-ft, which is greater than the required water quality volume, 0.094 ac-ft. Soil Restoration Excessively compacted areas and areas of cut and fill on the Project Site will have soil restoration applied as needed and as specified in the table below. Attached in Appendix H is "Deep Ripping and De-compaction, (DEC 2008)." This methodology should be followed for soil restoration as specified in the table below: Type of Soil Disturbance Soil Re storation Re quire me nt Comme nts/Example s Minimal Soil Disturbance Restoration not permitted Preservation of Natural Features Areas where topsoil is stripped Restoration not required Clearin and Grubbin only-no change in grade g g HSG A&B HSG C&D Areas of cut and fill apply 6 inches of Aerate*and apply topsoil 6 inches of topsoil Heavy traffic areas onsite HSG A&B HSG C&D (especially in a zone 5-25 feet around buildings,but not within a Aerate and apply 6 Apply full Soil 5 foot pernneter around �ches of topsoil Restoration** foundation walls) Keep construction equipment from Areas where Runoff Reduction Restoration not required,but may be crossing these areas.

Page 8 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 • Prior to application of the deep-ripping and de-compaction, the depth to bedrock or naturally occurring hardpan should be known so that the depth of tillage be adjusted according to those restrictive depths. • Soils with a slope that exceeds 10% will not have full soil restoration with deep-ripping and de-compaction due to potential for erosion from tilled soil. • Any soil tillage (deep or shallow) will not be done on soils that are excessively wet, as this will damage the soil. • Any tillage will not be done within approximately 10' of the drip-line of any existing established trees. • Any large stones that are unearthed during tillage should be removed from the surface prior to final surface preparation and vegetation establishment. 5.3 Post Construction Stormwater Management Drawings Post construction stormwater management controls are shown on Construction Drawings included in Appendix C. 5.4 Hydraulic and Hydrologic Analysis The program utilized for quantifying stormwater runoff rates and volumes was HydroCAD software, produced by Applied Microcomputer Systems of Chocorua, N H. The SCS 24-hour Type I I design storms for 1, 10, and 100-year freq uency rainfall were analyzed. ✓ Hydrologic/hydraulic analysis for all structural components of the stormwater control system for the applicable design storms (see Appendix B). ✓ Comparison of post-development stormwater runoff conditions with pre- development conditions (see Appendix B). ✓ Dimensions, material specifications and installation details for each post- construction stormwater control practice (see Appendix B and C). 5.5 Comparison of Pre and Post Construction Stormwater Runoff Stormwater Quantity.

Post-construction maintenance for this project will consist of regular inspections of permanent stormwater management facilities and steep slopes. These maintenance procedures are essential to assure continual performance of the stormwater management practices on your site. During the inspection and any maintenance activity to the stormwater management practices, the responsible party should fill out an inspection and maintenance log (Appendix E) to record that it was done. Annual inspections of the post construction stormwater management practices shall be completed and inspection reports shall be sent to the office of the City Engineer for their records. The City of Saratoga Springs shall approve a formal maintenance and inspection agreement in accordance with City Code Chapter 242 for stormwater management facilities to ensure the practices will be properly operated and maintained in accordance with the long term operation and maintenance plans. This agreement shall be binding on all subsequent land owners and recorded in the office of the County Clerk as a deed restriction on the property. Catch Basins (All) ■ Sediment removal with a vacuum truck should be done at least once a year, preferably after spring runoff and then in early fall, or when they are at 50% capacity, whichever comes first. ■ Any mechanical valves should be operated for inspection every two months. Vegetated Swale ■ Any accumulated sediment deposited into these areas needs to be removed by hand or very carefully with small equipment. Any ground disturbance should be minimized. � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C. Page �O Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 Stormwater Pond (Wet Pond) ■ Should be inspected twice a year and after heavy rain storms. ■ Any erosion or scour occurring in the pond, forebay or outlets shall be repaired and re-vegetated as needed. ■ Sediment removal in the forebay shall occur every five to six years or when 50% full. ■ Regular litter control to be performed as needed. Porous Pavement • During the winter, the spreading of sand or other particles for traction cannot be done. If the area is to be plowed of snow, this should be done carefully so as not to upset the permeable pavement. • Areas that receive high volumes of sediment will require frequent maintenance activities, and areas that experience high volumes of vehicular traffic will clog more readily due to soil compaction. Typical maintenance activities for permeable paving are summarized in the table below: T pical Maintenance Activities Associated with Permeable Pavement Activit Schedule Ensure pavin area is free of debris Monthl Ensure avin dewaters between storms Monthl and after storms >0.5" Ensure area is clean of sediments Monthl Mow upland and adjacent areas and seed As needed bare areas Vacuum sweep frequently to keep surface Typically 1 to 2 times a year free of sediments Inspect the surface for deterioration or Annually spallin ■ Generally, routine vacuum sweeping and high-pressure washing (with proper disposal of removed material and washwater) can maintain infiltration rates when clogged or crusted material is removed. Signs can also be posted visibly within a permeable paving area to prevent such activities as resurfacing, the use of abrasives, and to restrict truck parking. 7.0 CONSTRUCTION WASTE Waste Materials: All waste materials generated during construction will be disposed at a suitable landfill, or transfer station. � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C. Page �� Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 Hazardous Waste: The project will not be a generator of hazardous waste and it is not anticipated that any hazardous waste will be generated during construction. If there are any materials generated, a licensed hazardous waste carrier will be contracted to dispose the hazardous material at a suitable disposal site. If hazardous materials are d iscovered d u ri ng construction, the work wi I I be stopped u nti I the issue is resolved. Waste: Portable sanitary facilities will be made available to construction personnel and will be serviced regularly. 8.0 OFFSITE VEHICLE TRACKING Excavation equipment involved with the construction will remain on the project site and will not regularly egress or ingress the site. Any trucks used to bring in materials or remove materials via municipal paved roads will do so over a stabilized construction entrance. If any off-site vehicle tracking occurs, the contractor will be directed to initiate, street sweeping program in the immediate vicinity of the site. 9.0 TEMPORARYSTABILIZATION FOR FROZEN CONDITIONS The following temporary stabilization measures MUST be performed when construction is occurring during winter/frozen ground conditions. The following requirements do not supersede any other requirements of this SWPPP as they apply to non-frozen ground conditions. ■ Perimeter erosion control MUST still be installed prior to earthwork disturbance as per this SWPPP. ■ Any areas that can not be seeded to turf by October 1 or earl ier wi I I receive a temporary seeding. The temporary seeding will consist of winter rye seeded at the rate of 120 pounds per acre (2.5 pounds per 1,000 square feet) or stabilized as per the temporary stabilization for winter construction/frozen conditions. ■ Any area of disturbance that will remain inactive for a period of 14 consecutive days MUST be mulched. This includes any previously disturbed areas that are covered with snow. ■ Mulch MUST consist of loose straw applied at the rate of 2 to 3 bales (90 to 100 pounds) per thousand square feet. ■ Mulch MUST be applied uniformly over the area of bare soil or bare soil that is covered with snow. For the latter condition, mulch MUST be applied on top of snow. ■ Using a tracked vehicle, mulch MUST be crimped into the bare soil/snow. The tracked vehicle MUST be driven across the mulched areas in at least two directions to maximize crimping of mulch into the soil/snow. ■ If mulch gets blown off an area to a significant degree, the site inspector WILL require that an area be re-mulched in accordance with � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineering P.C. Page �2 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 Items 2 through 5 above, and this area WILL be included on the i nspection checkl ist for the next i nspection. ■ If a particular area repeatedly experiences loss of mulch due to wind, then the inspector WILL require that an alternative method be used to secure the mulch in place. Such alternatives may include the use of netting, tackifier or other methods deemed appropriate by the inspector. ■ During periods when snow is melting and/or surface soils are thawing during daytime hours, mulched areas MUST be re-tracked (crimped) as per Item 5 above at least once every seven days, more frequently if directed by the inspector. Additional mulch may be required to obtain complete coverage of an area. Biodegradable erosion control matting may be required on steeper slopes. ■ Additional stabilization measures for non-frozen ground conditions described in this SWPPP WILL be implemented at the time deemed appropriate by the inspector. During the winter season, if a site has been stabilized and soil disturbing activities have been suspended for the winter, weekly inspections can be suspended. However, monthly inspections must still be conducted. All normal weekly inspections must resume when soil disturbing activities resume. 10.0 SPILL PREVENTION PRACTICES Good Housekeeping and Material Management Practices The following good housekeeping and material management practices will be followed on site during the construction project to reduce the risk of spills or other accidental exposure of materials and substances to stormwater runoff. ■ Materials will be brought on site in the minimum quantities required. ■ All materials stored on site will be stored in a neat, orderly manner in their appropriate containers, and if possible, under a roof or other enclosure. ■ Products will be kept in their original containers with the original manufacturer's label. ■ Substances will not be mixed with one another unless recommended by the manufacturer. ■ Whenever possible, all of a product will be used up before disposal. ■ Manufacturer's recommendations for proper use and disposal will be fol lowed. ■ The construction manager or his designee will inspect regularly to ensure proper use and disposal of materials on site. ■ The contractor shall prohibit washing of tools, equipment, and machinery in or within 100 feet of any watercourse or wetland. ■ All above grade storage tanks are to be protected from vehicle damage by temporary barriers. � Th� LA GRC�U P L�ndscapeArc}�itecturec9.�nc3ineeringP.C.

Page 21 Stormwater Pollution Prevention Plan Saratoga Honda Building Expansion The LA Group Project # 201240.02 12.0 DEFINITIONS Construction Activity(ies) - means any clearing, grading, excavation, filling, demolition, or stockpiling activities that result in soil disturbance. Clearing activities can include, but are not limited to, logging equipment operation, the cutting and skidding of trees, tree removal, stump removal and/or brush removal. Construction activity does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of a facility. Construction Phasing Plan - a plan designed to construct particular portions of an individual project at different times. Phasing is often used when a project is very large to limit the disturbance at a single time to 5 acres per phase. Erosion and Sediment Control Practices — temporary measures installed prior to construction and maintained during construction to temporarily treat any stormwater runoff. Once construction is completed and post-construction stormwater management practices are installed and the site is stabilized, the erosion and sediment control practices are removed from the site. Final Stabilization - means that all soil disturbance activities have ceased and a uniform, perennial vegetative cover with a density of eighty (80) percent over the entire pervious surface has been established; or other equivalent stabilization measures, such as permanent landscape mulches, rock rip-rap or washed/crushed stone have been applied on all disturbed areas that are not covered by permanent structures, concrete pavement. Green Infrastructure — in the context of stormwater management, the term green infrastructure includes a wide array of practices at multiple scales to manage and treat stormwater, maintain and restore natural hydrology and ecological function by infiltration, evapotranspiration, capture and reuse of stormwater, and establishment of natural vegetative features. On a regional scale, green infrastructure is the preservation and restoration of natural landscape features, such as forests, floodplains and wetlands, coupled with policies such as infill and redevelopment that reduce overall imperviousness in a watershed or ecoregion. On the local scale green infrastructure consist of site and neighborhood specific practices and runoff reduction techniques. Such practices essentially result in runoff reduction and or establishment of habitat areas with significant utilization of soils, vegetation, and engineered media rather than traditional hardscape collection, conveyance and storage structures. Some examples include green roofs, trees and tree boxes, pervious pavement, rain gardens, vegetated swales, planters, reforestation and protection and enhancement of riparian buffers and floodplains. Impervious Area (Cover) - means all impermeable surfaces that cannot effectively infiltrate rainfall. This includes paved, concrete and gravel surfaces (i.e. parking lots, driveways, roads, runways, and sidewalks); building rooftops, and miscellaneous impermeable structures such as patios, pools, and sheds. � Th+e LA �R�DU P Lands�ape A��h�teEtu�P�_E��3�,�e���ny N.�.

It is prepared in accordance with the New York State Department of Environmental Conservation (NYSDEC) Stormwater Management Design Manual, dated January, 2015. The Proj ect has been designed in accordance with Chapter 4 of the NYSDEC Stormwater Management Design Manual (SWMDM), and NYSDEC's General Permit GP-0-20-001 for construction activities. Stormwater calculations were performed utilizing widely accepted engineering methodologies, including TR-55, and the stormwater modeling computer program HydroCAD (version 10.00) produced by HydroCAD Software Solutions, LLC. 2.0 PROJECT DESCRIPTION 2.1 Site Location The site is located to the southeast of the intersection of Route 9 and Crescent Avenue, located in the City of Saratoga Springs,NY. 2.2 Proj ect Description The proposed proj ect involves the construction of a 8.000 square foot building expansion and 18,000 square foot porous asphalt parking lot. The area of the proposed proj ect currently consists of a mixed of grassed, paved, and wooded areas. The remainder of the proposed site improvements includes construction of a site lighting, landscaping and stormwater controls. The proj ect is considered a new development proj ect per Chapters 4 of the SWMDM. The Proj ect Site represents the area that will be disturbed as a result of the Proj ect. 2.3 Soil Conditions/Soil Testing According to the Natural Resources Conservation Service (NRCS) Web Soil Survey, the area surrounding the Proj ect Site is comprised of Windsor loamy sand. The hydrological soil group classification for the soil is `A'. Soil testing in the form of deep hole test pits were performed in the locations of the proposed stormwater management facilities to identify subsurface soil conditions. The testing was performed on December 10, 2020 by The LA Group observed sand with seasonal high groundwater at a depth of 44"to 60". � Th+� LA �RC�U P l;ar-ij�.r_:i�a�'rarr_I�tl�r•i.lr+��a F'�_ +rif�_1 9�t_ 4 Stormwater Management Report Saratoga Honda Building Expansion 201240.02 2.4 Curve Numbers and Rainfall Data The surface cover for the proj ect area is grass and woods. The curve numbers utilized in the modeling were assigned based on cover type and HSG soil classification. The design storms used for the pre-development versus post-development comparison were the l, 10, and 100-year, 24-hour duration, SCS Type II events. The rainfall amounts for these storms are 2.15, 3.75, and 6.20 inches, respectively. 3.0 EXISTING CONDITIONS The Proj ect area existing condition, for which this stormwater management plan is based, consists of grass, woods, the existing Saratoga Honda building, parking lots and drives. There are five existing stormwater management practices indicated in Attachment B from previous phases of development at this proj ect site. Stormwater is generally infiltrated into underlying soils; but stormwater generally flows towards a wooded area to the south of the proj ect site. This is indicated on the plans as AP-1. Table 3-1 below provides a summary of the existing conditions peak discharge rates for the Proj ect's watershed. Table 3-1 Existin Conditions Peak Dischar e Rates Anal sis Point AP-1 Design Storm (cfs) 10-Year 0.0 100-Year 0.28 Refer to Attachment B for more information on the existing conditions watershed modeling. 4.0 PROPOSED CONDITIONS Under the watershed's Proposed Condition, stormwater from the Project will continue to discharge to the same point as in the Existing Condition (Analysis Point 1). The total watershed has generally remained unchanged, as is shown on the drawing "W-2 Proposed Conditions Watershed Map" contained in Attachment C. To meet NYSDEC requirements (see Section 5.0 NYSDEC Design Criteria of this report) porous pavement has been installed to manage the WQv required for the new impervious area created as a result of the proj ect. The existing capacities of the two existing pocket ponds were evaluated to ensure they could manage flows from additional impervious areas. � Th+� LA �RC�U P l;ar-ij�.r::v����r�rr_I�tl�c'llrt'�F'7� +'rif�_1 9�i_ 5 Stormwater Management Report Saratoga Honda Building Expansion 201240.02 Table 4-1 below provides a summary of the existing conditions versus proposed conditions peak discharge rates for the Project's watershed.

The Manual includes a five-step process that involves site planning and stormwater management practice selection. The five steps include; • Site planning to preserve natural features and reduce impervious cover, • Calculation of the Water Quality Volume (WQv) for the Site, • Incorporation of green infrastructure techniques and standard SMPs with Runoff Reduction Volume (RRv) capacity, • Use of standard SMPs where applicable, to treat the portion of WQv not addressed by green infrastructure techniques and standard SMPs with RRv capacity, and • Design of volume and peak rate control (where required) The approach of the stormwater management plan was to address the stormwater requirements separately. The five steps were reduced to Site Planning to Preserve Natural Features, Water Quality Volume, Runoff Reduction Volume, Channel Protection Volume, and Overbank Flood and Extreme Storm Attenuation, as discussed in the following sections. Attachment D of this report contains detailed calculations for determining and summarizing the required and provided volumes for Water Quality and Runoff Reduction. In general, the required design criteria (WQv and RRv) were calculated for all areas where site disturbance or green infrastructure techniques are proposed. � Th+� LA �RC�U P l;ar-ij�.r::v����r�rr_I�tl�c'llrt'�F'7� +'rif�_1 9�t_ 6 Stormwater Management Report Saratoga Honda Building Expansion 201240.02 5.1 Site Planning to Preserve Natural Features Within Chapter 3 of The Manual, Table 3.1 Green Infrastructure Planning General Categories and Specific Practices includes a list of planning practices utilized in the planning and design of a proj ect. There are two categories, Preservation of Natural Resources and Reduction of . Imperlous Cover. Preservation of Natural Resources includes: • Preservation of Undisturbed Areas • Preservation of Buffers • Reduction of Clearing and Grading • Locating Development in Less Sensitive Areas • Open Space Design • Soil Restoration Reduction of Impervious Cover includes: • Roadway Reduction • Sidewalk Reduction • Driveway Reduction • Cul-de-sac Reduction • Building Footprint Reduction • Parking Reduction A Natural Resource Map for Green Infrastructure Planning has been developed which indicates natural resource areas and critical environmental areas to be protected (where feasible). As required in Section 3.6 of The Manual, the map includes (where applicable): • Jurisdictional Wetlands o There are no wetlands located near the proj ect site. • Waterways o No waterways are impacted by the Project. • Wetland Adj acent Area o There are no wetlands located near the proj ect site. • Floodplains o The proj ect is not within the flood plain. • Forest, vegetative cover o Proj ect is designed to maintain as much of the woods as feasible. • Topography/Steep slopes o There are no steep slopes located throughout the project. • Existing soils, including hydrologic soil groups and soil erodibility o See Section 2.3 of this Report. � Th+� LA �RC�U P` I;�r•ij�.r:,c���I�rr_htl��.-'i.�rc��F�7��..,:a,rir�.;_�q�,_ � Stormwater Management Report Saratoga Honda Building Expansion 201240.02 • Drainage Patterns o See Section 3.0 of this Report. • Bedrock/Significant geological features o See Section 2.3 of this Report. The Natural Resource Plan indicates the areas to be avoided and depicts the area most suitable for development. 5.2 Water Quality Volume (WQv) The Water Quality Volume (WQv) requirement is designed to improve water quality sizing to capture and treat 90% of the average annual stormwater runoff volumes. The WQv is directly related to the amount of impervious cover created at a site. The following equation is used to determine the water quality storage volume. WQv = P Rv A 12 Where: WQv = Water quality volume (acre/feet) P = 90% Rainfall Event(1.15" for Saratoga Springs) Rv = 0.05 + 0.009(I) where I is percent impervious cover A = S ite are a in acre s The required WQv will be provided by porous pavement, a pocket pond, and an infiltration basin, modified and designed in accordance with the SWMDM. The total required WQv for the project is 0.094 ac-ft. Refer to Table 5-1 for a summary of the provided water quality volumes for the Proj ect. Table 5-1 Water Qualit Volume WQv Summar SMP Type Provided (ac-ft) Ex-SMP-1 Pocket Pond 0.025 Ex-SMP-2 Porous Pavement 0.040 SMP-3 Infiltration Basin 0.052 TOTAL 0.116 � Th+� LA �RC�U� l;ar-ij�.r::v����r�rr_I�tl�c'llrt'�F'7� +'rif�_1 9�t_ g Stormwater Management Report Saratoga Honda Building Expansion 201240.02 Refer to Attachment D for detailed WQv calculations. Note that the calculations shown indicate new impervious area and disturbed impervious area. 100% of the disturbed impervious area was treated as part of this proj ect because all impervious areas are currently directed to stormwater management practices. 5.3 Runoff Reduction Volume (RRv) Section 4.3 of the Manual states, "Runoff reduction shall be achieved by infiltration, groundwater recharge, reuse, recycle, evaporation/evapotranspiration of 100 percent of the post- development water quality volumes to replicate pre-development hydrology by maintaining pre- construction infiltration, peak runoff flow, discharge volume, as well as minimizing concentrated flow by using runoff control techniques to provide treatment in a distributed manner before runoff reaches the collection system." The Project achieves 100% runoff reduction of the on-site WQv of the project. Utilizing green infrastructure and stormwater management practices with RRv capabilities throughout the project an RRv of 0.116 acre-feet is provided. See Table 5-2 for a summary of the provided runoff reduction volumes for each green infrastructure practice.

It requires storage and attenuation of the 10-year, 24-hour storm to ensure post- development peak discharge rates do not exceed the pre-development condition. The intent of the Extreme Flood (Q� criteria is to (a) prevent the increased risk of flood damage from large storm events, (b) maintain the boundaries of the pre-development 100-year floodplain, and (c) protect the physical integrity of stormwater management practices. It requires storage and attenuation of the 100-year, 24-hour storm to ensure post-development peak discharge rates do not exceed the pre-development condition. During the 10-year and 100-year 24-hour storm the post-development peak discharge rates do not exceed the pre-development rates. See Table 4-1 of this Report for detailed comparison of pre- and post-development peak rates. 6.0 PROPOSED STORMWATER FACILITIES The Proj ect is proposing two stormwater management practices to treat stormwater: use of an existing pocket pond (Ex-SMP-1) and expansion of the existing porous pavement (Ex-SMP-2). The proj ect is also proposing the modification of an existing pocket pond due to site changes requiring its relocation (Ex-SMP-3); in lieu of a pocket pond the new design is proposing flows are directed to an infiltration basin. The stormwater facilities have been indicated on the plans and HydroCAD reports as Ex-SMP-I, Ex-SMP-2, and Ex-SMP-3 (Pre-Development), SMP-3 (Post-Development), Ex-SMP-4 and Ex-SMP-S are included in the plans and reports but are from previous phases of the proj ect and are included for information only. 6.1 Pretreatment Pretreatment of runoff from the disturbed impervious area for the existing pocket pond (Ex- SMP-1) is provided by a low area (P4.1) and a grass filter strip (2R) ahead of the pocket pond sized in accordance to the SWMDM. � Th+� LA �RC�U P L;�r•ij�.r.;c���farr_htlFc'i.�r.,.�F�7�...,:,,rir�;�9'i_ 1 O Stormwater Management Report Saratoga Honda Building Expansion 201240.02 Pretreatment of runoff from the standard asphalt drive to the porous pavement (Ex-SMP-2) is provided via low areas which hold 100% of the WQv prior to discharging to the porous pavement(P4.2, P4.3, and P4.4). Pretreatment for the infiltration basin (SMP-3) is provided via a vegetated swale and a basin. The vegetated swale worksheet (Appendix D) was used to verify that the WQv flowrate (0.92 cfs) required to provide the necessary pretreatment WQv (561 c�. The depth of flow in the swale at the WQv flowrate was determined using HydroCAD; when the swale receives a flow of 0.92 cfs, the depth of flow will be 0.33' (or 4"). At the WQv flowrate, the swale as designed meets the requirements for a vegetated swale per NYSDEC. The basin that will provide the remaining treatment volume has a capacity to store 1,697 cf of WQv prior to discharging via a weir into the infiltration basin. For all pretreatment calculations, refer to Appendix D. 6.2 Treatment Ex-SMP-1 (pocket pond) has a treatment capacity of 0.124 ac-ft based on the available volume in the pond below the outlet weir. The two subcatchments within the proj ect area that will be contributing to Ex-SMP-1 are 4.1 S and 4.65. The treatment required for the existing watershed is 0.068 ac-ft, and the treatment required for subcatchments 4.1 S and 4.6 S is 0.025 ac-ft. The total treatment required is 0.093 ac-ft, which is less than the current capacity of 0.124 ac-ft. It was therefore determined that the existing layout of Ex-SMP-1 will be adequate to manage contributions from the proj ect area, since the treatment capacity is currently greater than the post-construction contribution. Ex-SMP-1 will continue to outlet to a stormwater disposal area. Treatment at Ex-SMP-2 (porous pavement) will be provided via infiltration into underlying soils. There is currently a porous pavement parking lot in this area that the new porous pavement proposed will be tied into to provide one continuous parking lot. Ex-SMP-3 will be impacted by construction and has been redesigned as a result. SMP-3 is an infiltration basin at the south end of the new porous asphalt parking lot. Treatment will be provided via infiltration into the underlying soils. 7.0 POST-CONSTRUCTION MAINTENANCE REQUIREMENTS Saratoga Honda will be responsible for the continuous upkeep and maintenance of all stormwater management facilities. Maintenance includes, but is not limited to, cleaning of sediment from drainage inlet sumps, removal of sediment from SMPs, cleaning conveyance piping and channels of obstructions, inspection and repair as required of any outlet control mechanisms, and repairing any other detriments in the design that is resulting in the facilities to not function as intended in the design. � Th+� LA �RC�U P I.:�r•ij�.r;,c�.�farr�iElFc'i.�ri=�F�7�...,:,,rir�ta I'�_ 11 Stormwater Management Report Saratoga Honda Building Expansion 201240.02 7.1 REFERENCES 1.

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://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=nres) or your NRCS State Soil Scientist(http://soils.usda.gov/contact/ 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 orwet 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-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 scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report 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. 6 ■ o� a The soil map section includes the soil map forthe defined area of interest, a listof soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 7 Custom Soil Resource Report Soil Map N ' N � ti � � � 0 � � � ~ 598560 598640 598720 598800 598880 598960 599040 43°3'37" 43°3'37" , � - ,� Y, �j - ' � _ ��/� �■y � - ��/� �S./ � 9 � ,.. ..., - .. � \S./ r r ry� E � ry� W .� 3 � :.

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 itwas 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 10 Custom Soil Resource Report 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 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. 11 Custom Soil Resource Report Saratoga County, New York DeA—Deerfield loamy fine sand, nearly level Map Unit Setting Elevation: 0 to 1,000 feet Mean annual precipitation: 36 to 48 inches Mean annual air temperature: 45 to 48 deg rees F Frost-free period: 125 to 160 days Map Unit Composition Deerfield and similar soils: 75 percent Minor components: 25 percent Description of Deerfield Setti ng Landform: Deltas, outwash plains, terraces Landform position (two-dimensional): Summit Landform position (three-dimensional): Tread Down-slope shape: Concave Across-slope shape: Convex Parent material: Sandy glaciofluvial or deltaic deposits derived mainly from granite, gneiss, or sandstone Properties and qualities Slope: 0 to 3 percent Depth to restrictive feature: More than 80 inches Drainage class: Moderately well drained Capacity of the most limiting layer to transmit water(Ksat): H ig h to very h ig h (1.98 to 19.98 i n/h r) Depth to water table:About 18 to 36 inches Frequency of flooding: None Frequency of ponding: None Available water capacity: Low(about 3.8 inches) Interpretive groups Farmland classification: Farmland of statewide importance Land capability(nonirrigated): 3w Hydrologic Soil Group: A Typical profile 0 to 10 inches: Loamy fine sand 10 to 26 inches: Loamy fine sand 26 to 72 inches: Fine sand Minor Components Oakville Percent of map unit: 10 percent Claverack Percent of map unit: 7 percent Wareham Percent of map unit: 4 percent 12 Custom Soil Resource Report Wareham Percent of map unit: 4 percent DeB—Deerfield loamy fine sand, undulating Map Unit Setting Elevation: 590 to 1,000 feet Mean annual precipitation: 35 to 50 inches Mean annual air temperature: 45 to 48 deg rees F Frost-free period: 120 to 160 days Map Unit Composition Deerfield and similar soils: 75 percent Minor components: 25 percent Description of Deerfield Setti ng Landform: Deltas, outwash plains, terraces Landform position (two-dimensional): Summit Landform position (three-dimensional): Tread, rise Down-slope shape: Concave Across-slope shape: Convex Parent material: Sandy glaciofluvial or deltaic deposits derived mainly from granite, gneiss, or sandstone Properties and qualities Slope: 3 to 8 percent Depth to restrictive feature: More than 80 inches Drainage class: Moderately well drained Capacity of the most limiting layer to transmit water(Ksat): H ig h to very h ig h (1.98 to 19.98 i n/h r) Depth to water table:About 18 to 36 inches Frequency of flooding: None Frequency of ponding: None Available water capacity: Low(about 3.8 inches) Interpretive groups Farmland classification: Farmland of statewide importance Land capability(nonirrigated): 2w Hydrologic Soil Group: A Typical profile 0 to 10 inches: Loamy fine sand 10 to 14 inches: Loamy fine sand 14 to 26 inches: Loamy fine sand 26 to 44 inches: Fine sand 44 to 72 inches: Fine sand 13 Custom Soil Resource Report Minor Components Oakville Percent of map unit: 10 percent Claverack Percent of map unit: 7 percent Wareham Percent of map unit: 4 percent Landform: Depressions Wareham Percent of map unit: 4 percent WnA—Windsor loamy sand, nearly level Map Unit Setting Mean annual precipitation: 36 to 48 inches Mean annual air temperature: 45 to 48 deg rees F Frost-free period: 125 to 160 days Map Unit Composition Windsorand similarsoils: 80 percent Minor components: 20 percent Description of Windsor Setti ng Landform: Deltas, outwash plains, terraces Landform position (two-dimensional): Summit Landform position (three-dimensional): Tread Down-slope shape: Convex Across-slope shape: Convex Parent material: Sandy glaciofluvial or deltaic deposits Properties and qualities Slope: 0 to 3 percent Depth to restrictive feature: More than 80 inches Drainage class: Excessively drained Capacity of the most limiting layer to transmit water(Ksat): Moderately high to high (0.20 to 5.95 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Available water capacity: Low(about 5.4 inches) Interpretive groups Farmland classification: Farmland of statewide importance Land capability(nonirrigated): 3s Hydrologic Soil Group: A 14 Custom Soil Resource Report Typical profile 0 to 2 inches: Moderately decomposed plant material 2 to 11 inches: Loamy sand 11 to 25 inches: Loamy sand 25 to 72 inches: Loamy sand Minor Components Deerfield Percent of map unit: 10 percent Hinckley Percent of map unit: 5 percent Oakville Percent of map unit: 5 percent 15 e erences American Association of State Highway and Transportation Officials(AASHTO).2004.
