Stormwater Pollution Prevention Plan (SWPPP) is prepared to inform the landowner and construction personnel of the measures to be implemented for controlling runoff and pollutants from the site during and after construction activities. 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 following information: ✓ 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 (July 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." The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 1 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 2.0 SWPPP REVIEW, UPDATE 2.1 SWPPP Review Applicable Federal, State, and local regulatory agencies that have jurisdiction may elect to review this SWPPP and notify the permittee in writing that the SWPPP does not meet the requirements of their regulations. If the SWPPP needs to be revised, the permittee and the site contractor will make the required modifications within seven days of such notification and submit written certification to the notifying agency that the changes have been implemented. A copy of the SWPPP will be kept available on site for review by regulatory agencies, engineers, and subcontractors. This Project is in the City of Saratoga Springs which is a regulated MS4 Community, so a copy of this SWPPP was sent to the City for review. A copy of the signed MS4 Acceptance form is provided in Appendix A of this SWPPP. 2.2 SWPPP Update The permittee identified in this SWPPP shall amend the SWPPP under the following conditions: ✓ Whenever the current provisions prove to be ineffective in minimizing pollutants in stormwater discharge from the site ✓ Whenever there is a change in design, construction or operation that could have an effect on the discharge of pollutants ✓ To address issues or deficiencies identified during an inspection by the qualified inspector, the Department or other regulatory authority ✓ To identify a new subcontractor that will implement any part of the SWPPP. If modifications are required to the post-stormwater management practices and the Project is within a regulated, traditional land use control MS4, the owner or operator of the Project must notify the MS4 in writing of any planned amendments or modifications to the post-construction stormwater management practice component of the SWPPP. Unless otherwise notified by the MS4, the owner or operator shall have the SWPPP amendments or modifications reviewed and accepted by the MS4 prior to commencing construction of the post-construction stormwater management practice. The SWPPP PLAN CHANGES, AUTHORIZATION, AND CHANGE CERTIFICATION form (Appendix E) must be filled out and a copy retained onsite during construction.

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 ✓ Concrete washout — Maintenance shall be performed as needed to ensure that the washout is structurally sound and no contamination reaches the below or surrounding soil during the washout of a concrete truck. Material shall be removed and disposed of once it has hardened. L The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 6 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 ✓ Inlet protection — Inlet protection shall be replaced or debris shall be removed when inlet protection reaches greater than 50% capacity. ✓ 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. ■ 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 L The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 7 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 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 CONSTRUCTION STORMWATER MANAGEMENT PRACTICES 5.1 Stormwater Management Controls The proposed Post Construction Stormwater Management controls on this project are listed below: ✓ Underground Infiltration Chambers ✓ Vegetated Filter Strip 5.2 Green Infrastructure Practices/Runoff Reduction Techniques The proposed Green Infrastructure practices or Standard Management practices with Runoff Reduction capabilities on this project are listed below: ✓ Underground Infiltration Chambers ✓ Vegetated Filter Strip The provided runoff reduction volume is 0.094 ac-ft, which is greater than the required WQv of 0.091 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: The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 8 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 Type of Soil Disturbance Soil Restoration Requirement Comments/Examples Minimal Soil Disturbance Restoration not permitted Preservation of Natural Features Areas where topsoil is stripped Restoration not required Clearing and Grubbing only-no change in grade 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 perimeter around inches of topsoil Restoration** foundation walls) Keep construction equipment from Areas where Runoff Reduction Restoration not required,but may be crossing these areas. To protect and/or infiltration practices are applied to enhance the reduction newly installed practice from any applied specified for appropriate practices ongoing construction activities construct a single phase operation fence area. *Aeration includes the use of machines such as tractor-drawn implements with coulters making a narrow slit in the soil,a roller with many spikes making indentations in the soil,or prongs which function like a mini-subsoiler **Per'Deep Ripping and Decopmpaction,DEC 2008" • If compost amendment is required, 2 to 4 inches of screened compost will be incorporated into the soil. • 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 1 Or 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 LA GROUP Landscape Arch Beciure&Engineering P.C. Page 9 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 The program utilized for quantifying stormwater runoff rates and volumes was HydroCAD software, produced by Applied Microcomputer Systems of Chocorua, NH. The SCS 24-hour Type II design storms for 1, 10, and 100-year frequency 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.

The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 10 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 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. 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 ruing the prior year." The City of Saratoga Springs shall approve a formal maintenance and inspection agreement in accordance with the 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 landowners and recorded in the office of the County Clerk as a deed restriction on the property. Underground Infiltration Chambers ■ The systems should be inspected quarterly for the first year and if there are no problems, the system can be inspected annually after the first year. ■ If sediment is accumulating on the bottom of the system, pump in water via a flushing port or observation well and then pump the sediment laden water out via the flushing port or the inlet. This can be done with a vacuum truck. The system may have to be flushed multiple times until it is clean of sediment. ■ Also, the manifold feeding the pipe storage should be flushed by pumping water in the manhole access and out the flushing port. This should be done during the routine inspection. Filter Strip ■ Channelization and erosion need to be identified and repaired promptly and bare areas seeded. If used, the level spreader should be checked and repaired as needed. �. The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 11 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 ■ 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. ■ Filter strips should be maintained as dense turf/riparian buffer. Area should be re- seeded as necessary. Catch Basins ■ 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. 7.0 CONSTRUCTION WASTE Waste Materials: All waste materials generated during construction will be disposed at a suitable landfill, or transfer station. 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 discovered during construction, the work will be stopped until 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 TEMPORARY STABILIZATION 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. The LA GROUP L..decayeA,chil-4 &EnVw-rmgPC Page 12 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 ■ Any areas that cannot be seeded to turf by October 1 or earlier will 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 Items 2 through 5 above, and this area WILL be included on the inspection checklist for the next inspection. ■ 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 LA GROUP Landscape Arch Beciure&Engineering P.C. Page 13 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 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 followed. ■ 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. Inventory for Pollution Prevention Plan The materials and substances listed below are expected to be on-site during construction. ■ Petroleum for fueling vehicles will be stored in above ground storage tanks. Tanks will either be steel with an enclosure capable of holding 110% of the storage tank volume or of a Con-Store, concrete encased type typically employed by NYSDOT. Hydraulic oil and other oils will be stored in their original containers. Concrete and asphalt will be stored in the original delivery trucks. ■ Fertilizer may be stored on site in its original container for a short period of time prior to seeding. Original containers will be safely piled on pallets or similar devices to protect from moisture. ■ Paints and other similar materials will be stored in their original containers and all empty containers will be disposed of in accordance with label directions. ■ Portable sanitary facilities, which contain chemical disinfectants (deodorants) will be located on-site, with the disinfectants held in the tank of the toilet. Hazardous Products These practices are used to reduce the risks associated with hazardous materials. L The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 14 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 ■ Products will be kept in original containers unless they are not re- sealable. ■ Original labels and material safety data sheets will be retained; they contain important product information. ■ If surplus product must be disposed of, manufacturers' or local and State recommended methods for proper disposal will be followed. Spill Prevention The following product specific practices will be followed on site. Petroleum Products: ■ Construction personnel should be made aware that emergency telephone numbers are located in this SWPPP. ■ The contractor shall immediately contact NYSDEC in the event of a spill, and shall take all appropriate steps to contain the spill, including construction of a dike around the spill and placing absorbent material over this spill. ■ The contractor shall instruct personnel that spillage of fuels, oils, and similar chemicals must be avoided and will have arranged with a qualified spill remediation company to serve the site. ■ Fuels, oils, and chemicals will be stored in appropriate and tightly capped containers. Containers shall not be disposed of on the project site. ■ Fuels, oils, chemicals, material, equipment, and sanitary facilities will be stored/located away from trees and at least 100 feet from streams, wells, wet areas, and other environmentally sensitive sites. ■ Dispose of chemical containers and surplus chemicals off the project site in accordance with label directions. ■ Use tight connections and hoses with appropriate nozzles in all operations involving fuels, lubricating materials or chemicals. ■ Use funnels when pouring fuels, lubricating materials or chemicals. ■ Refueling and cleaning of construction equipment will take place in parking areas to provide rapid response to emergency situations. ■ All on-site vehicles will be monitored for leaks and receive regular preventative maintenance to reduce the chance of leakage. Any vehicle leaking fuel or hydraulic fuel will be immediately scheduled for repairs and use will be discontinued until repairs are made. Fertilizers: ■ Fertilizer will be stored in its original containers on pallets with water resistant coverings. ■ Proper delivery scheduling will minimize storage time. ■ Any damaged containers will be repaired immediately upon discovery and any released fertilizer recovered to the fullest extent practicable. L The LA GROUP Landscape Arch Beciure&Engineering P.C. Page 15 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 Paints: ■ All containers will be tightly sealed and stored when not required for use. ■ Excess paint will not be discharged to the storm water system or wastewater system, but will be properly disposed of according to manufacturers' instructions or State and local regulations. Concrete Trucks: ■ Concrete trucks will be allowed to wash out or discharge surplus concrete or drum wash water only at designated locations on site. Asphalt Trucks: ■ Asphalt trucks shall not discharge surplus asphalt on the site. Spill Control Practices In addition to the good housekeeping and material management practices discussed in the previous sections of this plan, the following practices will be followed for spill prevention and cleanup. The construction manager or site superintendent responsible for the day-to-day site operations will be the spill prevention and cleanup coordinator. He will designate at least three other site personnel who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The names of responsible spill personnel will be posted in the material storage area and in the onsite construction office or trailer. ■ Manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. Any spill in excess or suspected to be in excess of two gallons will be reported to the NYSDEC Regional Spill Response Unit. Notification to the NYSDEC (1-800-457-7362) must be completed within two hours of the discovery of the spill. ■ Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials will include but not be limited to absorbent pads, brooms, dust pans, mops, rags, gloves, goggles, activated clay, sand, sawdust, and plastic and metal trash containers specifically for this purpose. ■ All spills will be cleaned up immediately after discovery.

Page 22 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 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. La The LA GROUP Page 23 Stormwater Pollution Prevention Plan Excelsior Park Apartments — Beacon The LA Group Project # 2020047 Municipal Separate Storm Sewer (MS4) — a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains): i. Owned or operated by a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under State law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under section 208 of the CWA that discharges to surface waters of the State. ii. Designed or used for collecting or conveying stormwater iii. Which is not a combined sewer iv. Which is not part of a Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. Notice of Intent — a standardized format notification sent to the NYSDEC to inform them of the proposed activity to be sent after the SWPPP has been completed. Owner or Operator— means the person, persons or legal entity which owns or leases the property on which the construction activity is occurring; and/or an entity that has operational control over the construction plans and specifications, including the ability to make modifications to the plans and specifications. Post-Construction Stormwater Management Practices — permanent devices constructed or installed onsite to treat stormwater from a site when construction is completed. Qualified Inspector— means a person that is knowledgeable in the principles and practices of erosion and sediment control, such as a licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, or other Department endorsed individual(s). It can also mean someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided that person has training in the principles and practices of erosion and sediment control. Training in the principles and practices of erosion and sediment control means that the individual working under the direct supervision of the licensed Professional Engineer or Registered Landscape Architect has received four (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 individual working under the direct supervision of the licensed Professional Engineer or Registered Landscape Architect shall receive four (4) hours of training every three (3) years. It can also mean a person that meets the Qualified Professional qualifications in addition to the Qualified Inspector qualifications. Qualified Professional — means a person that is knowledgeable in the principles and practices of stormwater management and treatment, such as a licensed Professional L The LA GROUP Landscape Arch Beciure&Engineering P.C.

It is prepared in accordance with the New York State Department of Environmental Conservation (NYSDEC) Stormwater Management Design Manual, dated January, 2015. The Project 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 Project is located off Excelsior Avenue in the City of Saratoga Springs, Saratoga County, NY 12866. Access to the site is off Excelsior Avenue and Whistler Court. 2.2 Project Description The Project includes the construction of a new mixed-use building. The remainder of the proposed site improvements include the continuation of Whistler Court, parking lots, site lighting, landscaping, stormwater controls, and connections to municipal water and sewer. The project is considered a new development project per Chapter 4 of the SWMDM. The Project Site represents the area that will be disturbed as a result of the Project. 2.3 Soil Conditions/Soil Testing According to the Natural Resources Conservation Service (NRCS) Web Soil Survey, the area surrounding the Project Site is comprised of Windsor loamy sand and Udorthents. The hydrological soil group classifications for the soil groups are `A' and `C' respectively. Test pits and falling head permeability tests were completed by The LA Group in October 2020. Results of the tests are provided in Attachment B. 2.4 Curve Numbers and Rainfall Data The surface cover for the project area is woods and grass. The curve numbers utilized in the modeling were assigned based on cover type and HSG soil classification. ko The LA GROUP Landscape Am hite are&Engio rmg P.C. 4 Stormwater Management Report Excelsior Park Apartments—Beacon 2020047 The design storms used for the pre-development versus post-development comparison were the 1, 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 Project area existing condition, for which this stormwater management plan is based, consists of woods and grass. Under the watershed's Existing Condition, runoff flows off site to the southwest and southeast. The majority of the Project area (Sub-catchment 1) sheet flows southwest to an off-site wetland area (Analysis Point 1). The eastern portion of the site (Sub- catchment 2) flows southeast to existing stormwater infrastructure in Whistler Court (Analysis Point 2). The Analysis Points were utilized in comparing all pre- versus post-runoff conditions. Refer to drawing "W-1 Existing Conditions Watershed Map," located in Attachment B for more information. Table 3-1 below provides a summary of the existing conditions peak discharge rates for the Project's watershed. Table 3-1 Existing Conditions Peak Discharge Rates Analysis Point AP-1 AP-2 Design Storm (cfs) (cfs) 10-Year 0.48 0.00 100-Year 1.25 0.09 Refer to Attachment B for more information on the existing conditions watershed modeling. 4.0 PROPOSED CONDITIONS Under the watershed's Proposed Condition, all stormwater from the Project will continue to discharge to the same points as in the Existing Condition (Analysis Point-1 & Analysis Point-2). 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) underground infiltration chambers have been incorporated into the stormwater management design to mitigate the quality and quantity of stormwater runoff discharged from the Project Site. 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. 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 project. There are two categories, Preservation of Natural Resources and Reduction of Imperious Cover. L@ The LA GROUP l 0.Am hire are&Enginee g P.C. 6 Stormwater Management Report Excelsior Park Apartments—Beacon 2020047 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 wetlands located adjacent to the site. These wetlands will not be impacted as part of this project. • Waterways o No waterways are impacted by the Project. • Wetland Adjacent Area o There are wetlands located to the south of the site. The development does not impact NYSDEC wetland buffer areas. • Floodplains o The project is not within the flood plain. • Forest, vegetative cover o Project is designed to maintain as much of the woods as feasible. • Topography/Steep slopes o There are steep slopes located throughout the project. The development is situated to preserve these slopes to the greatest extent feasible. • Existing soils, including hydrologic soil groups and soil erodibility o See Section 2.3 of this Report. • Drainage Patterns o See Section 3.0 of this Report. • Bedrock/Significant geological features ko The !LA GROUP Landscape Am hite are&Engio rmg P.C. 7 Stormwater Management Report Excelsior Park Apartments—Beacon 2020047 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 = Site area in acres The total required WQv for this project based on the entire contributing area is 0.091 acre-ft. The project proposes the use of a vegetated filter strip as well as underground infiltration chambers designed in accordance with the SWMDM to adequately reduce and treat the required WQv. Vegetated filter strips are an area reduction practice. Therefore, the area being directed to the filter strip has been removed from the total required WQv of 0.091 acre-ft to produce an adjusted WQv of 0.082 acre-ft. The difference between the total required and adjusted WQv is 0.009 acre- ft which is effectively the volume treated by the filter strips. Refer to Table 5-1 for a summary of the provided water quality volumes for the Project. Refer to Attachment D for WQv calculations. Table 5-1 Water Quality Volume Qv Summary SMP Type Provided (ac-ft) SMP 1 Vegetated Filter Strip 0.009 SMP2 Infiltration Chambers 0.085 TOTAL 0.094 Refer to Attachment D for detailed WQv calculations. 5.3 Runoff Reduction Volume (RRv) The LA GROUP Landscape Am hite are&Engio rmg P.C. 8 Stormwater Management Report Excelsior Park Apartments—Beacon 2020047 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. See Table 5-2 for a summary of the provided runoff reduction volumes for each green infrastructure practice. Table 5-2 Runoff Reduction Volume RRv Summar SMP Provided (unit) 5.3.1 Conservation of Natural Areas - 5.3.2 Sheetflow to Riparian Buffers/Filter Strips 0.009 (SMP-1) 5.3.3 Vegetated Open Swales - 5.3.4 Tree Planting/Tree Box - 5.3.5 Disconnection of Rooftop Runoff - 5.3.6 Stream Daylighting - 5.3.7 Rain Garden - 5.3.8 Green Roof - 5.3.9 Stormwater Planters - 5.3.10 Rain Tanks/Cisterns - 5.3.11 Porous Pavement - Underground Infiltration Chambers (SMP-2) 0.085 TOTAL 0.094 (ac-ft) Refer to Attachment D for detailed RRv calculations. 5.4 Channel Protection Volume (CPv) Stream Channel Protection Volume (CPv) requirements are designed to protect stream channels from erosion. In New York State, this goal is accomplished by providing 24-hour extended detention of the one-year, 24-hour storm event. The required CPv is calculated utilizing TR-55 (or TR-20) and Appendix B of The Manual. The entire CPv is reduced through proposed green infrastructure and infiltration systems.

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 (Qf) 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 Project is proposing the installation of a vegetated filter strip and underground infiltration chambers to address stormwater requirements for the project. The stormwater facilities have been indicated on the plans and HydroCAD reports as SMP-1 & SMP-2. SMP-1 is the vegetated filter strip and will treat runoff from the southern portion of the proposed roadway. SMP-2 is the underground infiltration system in the parking lot south of the mixed-use building and will treat runoff from the northern portion of the proposed roadway, the mixed-use building, and the adjoining parking lot. The Stormwater Facilities have been designed to provide the necessary pretreatment, treatment, and peak rate attenuation for stormwater runoff, for the project, as required by NYSDEC. 6.1 Pretreatment Runoff contributing to the underground infiltration chambers (SMP-2) is pretreated through an isolator row. Due to permeability rate of underlying soils, 100% of the WQV is required to be pretreated. Per TARP and TAPE approved evaluation the isolator row provides a treatment rate of 0.006 cfs/sf. SMP-2 requires pretreatment of 3,819 cf. The isolator row in SMP-2 provides (9) MC-3500 chambers, which equates to 378 s.f of pretreatment area, or a 2.268 cfs (378 sf x 0.006 cfs/sf) treatment flow rate. A flow rate of approximately 1.66 cfs has a total contributing runoff volume of 3,843 cf for a Type II-24 hour The LA GROUP . :1-ape Am h,t are&Enginee g P.C. 10 Stormwater Management Report Excelsior Park Apartments—Beacon 2020047 storm event. The maximum pretreatment flowrate of the isolator row in SMP-2 (2.268 CFS) is greater than the contributing WQv flow rate (1.66 cfs) and therefore meets the pretreatment requirement. 6.2 Treatment Treatment for the vegetated filter strip (SMP-1) is provided by the sheet flow of stormwater over a shallowly sloped grass area. A level spreader has been incorporated into the design to ensure sheet flow occurs over the vegetated surface. Treatment for the underground infiltration chambers (SMP-2) is provided by capturing and treating the entire WQv through infiltration into the underlying soils. 7.0 POST-CONSTRUCTION MAINTENANCE REQUIREMENTS Beacon Communities, LLC 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 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. 8.0 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://www.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https:Hoffices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_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 Custom Soil Resource Report 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 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of 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. 8 Custom Soil Resource Report Soil Map 871140 601160 601190 6D1290 601220 601240 871230 671297 871370 601329 43-5'40^N 43-s 40'N WnB c c R c � c Sufi Mari may nat he valid at alk scale. 43°5' "N v 43°3 36 N 871140 6D116D 601190 6D1210 871220 601240 601280 B712B0 8713]0 871320 3 3 - Map Scale:1:906 if printed on A landsope(11"x 8.5")sheet. - N Mimes 0 10 29 40 B] A 0 0 4o m ,� zoo Map projection:Wee Mercator Cnmerocordinates:WGS84 Edge tics:UTM Zone 18N WGS84 9 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest(AOI) Spoil Area The soil surveys that comprise your AOI were mapped at Area of Interest(AOI) Stony Spot 1:24,000.

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 Iandforms or Iandform 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, 11 Custom Soil Resource Report 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. 12 Custom Soil Resource Report Saratoga County, New York Ue—Udorthents, smoothed Map Unit Setting National map unit symbol: 9wcz Elevation: 20 to 840 feet Mean annual precipitation: 36 to 48 inches Mean annual air temperature: 45 to 48 degrees F Frost-free period. 125 to 160 days Farmland classification: Not prime farmland Map Unit Composition Udorthents, smoothed, well drained, and similar soils: 80 percent Minor components:20 percent Estimates are based on observations, descriptions, and transects of the mapunit.

This determination is based on the information submitted by the LA GROUP on December 2nd, 2020 and reviewed by staff from the Division of Fish, Wildlife, and Marine Resources. Though Karner blue butterflies (Lycaeides melissa samuelis) are known to occur near your project location, they are not located on the subject parcel, and the DEC does not anticipate your proposed action to result in a take. Therefore, no permit is required at this time pursuant to the implementing regulations (6NYCRR Part 182) of the New York State Endangered Species Act (Article 11- 0535).
