PROJECT BACKGROUND INFORMATION The proposed two (2) lot subdivision, including an existing and a proposed single- family residence, is located on 42 Ruggles Road, in the City of Saratoga Springs, County of Saratoga, State of New York. The property is identified as Tax/Map parcel # 154.-1-23.1. The 10.3 acre parcel will be subdivided into two (2) single-family lots where a single family dwelling is to be constructed along the existing road frontage along 44 Ruggles Road (Lot 2). This new residential lot will be serviced by an on- site conventional septic system and new service lateral connecting to the municipal water system. There is an existing single-family house with an on-site septic system that will remain at 42 Ruggles Road (Lot 1). Lot 1 has an area of approximately 7.3 acres and Lot 2 is 3.0 acres. The area of disturbance on Lot 2 is associated with the construction of a house, driveway,the water service and the on-site septic system with a disturbance area of approximately 0.9+/- acres. If soil disturbance is rounded to greater than 1 acre, this project type is listed under Table 1 Appendix B of the NYSDEC GP-0-15-002 and will require a SWPPP that includes only Erosion and Sediment Control (projects which will result in disturbance greater than 1 acre, but less than five acres). Site Characteristics The Saratoga County Soils Map (Appendix A) shows the soils within the area of development to be Oakville loamy fine sand (OaB) undulating, Oakville loamy fine sand (OaC) rolling. Endangered or Threatened Species The NYSDEC Environmental Resource Mapper on the NYSDEC website and the USFWS website were reviewed to determine the likelihood of state or federally listed T&E species or critical habitat areas existing within the project parcel. Review by the U.S. Fish and Wildlife Service identified the site to be within the range of the Northern Long-eared Bat and the Karner Blue Butterfly. Their records show no critical habitat within the project area and office/field reviews by Ingalls biologists revealed no suitable habitat for the NLEB, Butterflies or Wild Lupine host plant (Appendix E). Cultural Resources Through coordination with the OPRHP and NYSDEC databases the project site was determined not to be in an Archeological sensitive area (See SEAF and OPRHP documentation regarding Cultural Resources and Historic Properties in Appendix E). SWPPP Page 11 II. STORMWATER MANAGEMENT OBJECTIVES The primary stormwater management objective is to maintain water quality during construction phases and to ensure reestablishment of proper cover in the developed area to lessen the impacts to downstream water channels and properties. Sources of water pollution during construction typically include erosion, siltation, and debris transport from excavated site areas, accidental spillage or leakage of motor fuels, lubrication oils, and other fluids from construction equipment, and other potential releases of construction related debris. In post construction,typical pollution sources include leakage of motor fuel or lubricating oils onto pavement, sediment-laden runoff from paved areas after deicing procedures, and runoff from landscaped areas that may contain fertilizers and other landscape maintenance chemicals. Stormwater quality and erosion control during construction will utilize temporary measures including installation of silt fencing, vegetation protection barriers, and if needed, stone check dams to minimize soil erosion and water pollution. Currently the center portion of the site drains to an unnamed intermittent stream which flows from east to west through the center of the site ultimately to an existing 15" culvert under Ruggles Road. This location is identified as analysis point A. The southern portion of the site drains towards the southwest to corner of the property and is identified as analysis point B. The far northern portion of the property drains towards the lands of Raga to the north. This location is identified as analysis point C. This drainage pattern will be maintained after construction. Any minor increase in runoff associated with the construction of the house and driveway will be negligible and mitigated through establishment of a swale line and slight depression along the south side of the proposed driveway on Lot 2. This small basin will attenuate stormwater flows such that post development discharge rates will be equal or less than pre developments conditions. As the below table demonstrates the proposed development will not negatively alter hydrology of the site. The peak flow rates for the post development conditions are equal to or less than the existing, predevelopment conditions of the property.

EROSION & SEDIMENT CONTROL L Temporary Controls during Construction During the project's construction phase the site will be the most susceptible to erosion and sedimentation. To prevent erosion during the construction phase,the following temporary erosion control measures will be used. • Silt fencing will be placed around proposed toe of slopes. • Tracking pads (Stabilized Construction Entrances) shall be constructed at site entrance. • Silt fence shall be constructed around all temporary stockpiles of fill, topsoil, and excavated overburden. Silt fence shall be maintained in good condition until such time as said stockpiles are removed and stockpiling areas are brought to final grade and permanently stabilized. • Seeding/mulch shall be used to stabilize inactive areas of topsoil and fill that is to remain stockpiled on-site for periods greater than 14 days. Prior to the seeding operation,the stockpiled material shall be graded as needed and feasible to permit the use of conventional equipment for seedbed preparation, seeding, mulch application and mulch anchoring. • If applicable, all disturbed slopes greater than 3:1 shall receive biodegradable rolled fabric to protect slopes from erosion. • Water trucks will be used for dust control on roadways. • Site debris and rubbish shall be properly disposed of daily. • Stockpiled construction materials shall be covered,contained and elevated • The contractor shall avoid the use of toxic products and materials to the maximum extent. • Spill control supplies and Material Safety Data Sheets (MSDS) shall be stocked and maintained in readily accessible locations. All temporary controls must be functioning and left in-place until the entire contributing area treated by the practice reaches final stabilization. Temporary controls associated with individual lots may be installed prior to the construction of that lot and removed once the full area is finally stabilized. All Erosion & Sediment Control practices shall be installed and maintained in accordance with "NYS Standards for Erosion &Sediment Control" (2016-Blue Book). Site Assessment and Inspections All erosion and sediment control measures shall be routinely inspected by the owner or his representative to ensure control measures are functioning properly at all times. At a minimum, routine inspections should take place after all heavy storm events. Erosion control devices shall be cleaned and repaired as necessary to insure proper operation. SWPPP Page 13 Per the City of Saratoga Springs Stormwater ordinance, the owner/operator shall maintain a record of all project documents including the SWPPP and any inspection reports the duration of the project. Stabilization The operator shall initiate stabilization measures as soon as practical in portions of the site where construction activities have temporarily or permanently ceased,but in no case more than 14 days after the construction activity in the portion of the site has temporarily or permanently been ceased. The soil stabilization measures selected shall be in conformance with the most current version of the technical standard,"New York Standards and Specifications for Erosion and Sediment Control." This requirement does not apply when construction activity is temporarily or permanently ceased due to snow cover or frozen ground conditions. In this case stabilization measures shall be initiated as soon as practicable. Winter Stabilization The following measures shall apply for construction activities involved with land disturbance and exposure between November 15th and April 1st. • Ensure adequate storage is provided for cleared snow and control of melt water in a manner not affecting ongoing construction activities. • Enlarge and stabilize access points for snow management and stockpiling. Snow management activities must not destroy or degrade installed erosion and sediment control practices. • A minimum 25 foot buffer shall be maintained from all perimeter controls such as silt fence. Mark silt fence with tall stakes that are visible above the snow pack. • Sediment barriers must be installed at all appropriate perimeter and sensitive locations. As applicable silt fence and other practices requiring earth disturbance shall be installed before the ground freezes. • Soil stockpiles must be protected by the use of established vegetation, anchored straw mulch, rolled stabilization matting, or other durable covering.A barrier must be installed at least 15 feet from the toe of the stockpile to prevent soil migration and to capture loose soil. • In areas where soil disturbance activity has temporarily or permanently ceased,the application of soil stabilization measures should be initiated by the end of the next business day and completed within three (3) days. Rolled erosion control blankets must be used on all slopes 3 horizontal to 1 vertical or steeper. • If straw mulch alone is used for temporary stabilization, it shall be applied at double the standard rate of 2 tons per acre, making the application rate 4 tons per acre. Other manufactured mulches should be applied at double the manufacturer's recommended rate. SWPPP Page 14 • To ensure adequate stabilization of disturbed soil in advance of a melt event, areas of disturbed soil should be stabilized at the end of each work day unless: o work will resume within 24 hours in the same area and no precipitation is forecast or; o the work is in disturbed areas that collect and retain runoff, such as open utility trenches, foundation excavations, or water management areas. Maintenance The owner/operator shall inspect the integrity and function of all temporary erosion control measures to ensure they are being maintained in effective operating condition at all times. To assure proper function, siltation barriers shall be maintained in good condition and reinforced, extended, repaired, re-seeded and protected from further erosion. All accumulated sediment shall be removed and contained in appropriate spoil areas.Water shall be applied to newly seeded areas as needed until grass cover is well established. Sedimentation control measures shall be monitored to ensure proper functionality. The following items shall be routinely inspected by the owner. • Silt fencing shall be inspected regularly for undermining and deterioration. • Seeded/mulched areas shall be inspected regularly to see that a good stand is maintained without erosion.Areas shall be repaired as necessary. • The construction entrance(s) shall be maintained in a condition, which will prevent tracking or flowing of sediment onto public R.O.W. All sediment spilled, dropped, washed or tracked onto public R.O.W. must be removed immediately. • The site shall be visually inspected for residues, stains or traces of pollutants on paved surfaces and around structures or valves. Erosion control devices must be cleaned when sediment reaches 50%. SWPPP Page 15 IV. SUMMARY The erosion and sediment measures as well as attenuation controls referenced above will prevent flooding, nutrient loading, and erosion that may result during construction. This will ensure proper protection of downstream channels, wetlands and adjacent properties. Based on the previously described stormwater controls,the proposed new lot development will not negatively impact downstream properties. The controls and maintenance responsibilities outlined in this report shall be cross referenced with the NYSDEC GP 0-15-002. The contractor shall be familiar with both the design plans and reports and the NYS Permit conditions.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

The subject parcel is 10.3 ± acres and can be identified by tax map ID: 154.00-1-23.1. On September 28, 2018 a qualified environmental biologist from Ingalls and Associates conducted a site walkover to analyze the onsite habitat and survey for individuals of the species listed below. The subject site primarily consists of mature deciduous forest which includes Red Maple (Acer rubrum), Quaking Aspen (Populus tremuloides), and American Hornbeam (Carpinus caroliniana). A review of the subject site concluded that there was no sufficient habitat or presence of the Karner Blue Butterfly (Lycaeides melissa samuelis), frosted elfin (Callophrys irus) and the Northern Long Eared Bat (Myosis septentrionalis). Please find below further details regarding characteristics for suitable habitat for both species mentioned above. Karner Blue Butterfly (Lycaeides melissa samuelis, Endangered) Karner Blue Butterflies are typically found within the northern range of wild lupine habitat. Karner Blue Butterflies primarily utilize Wild Lupine (Lupinus perennis) which are often found within sandy pine barrens. Karner blue butterfly habitat consist of a patchwork of pine and scrub oak scattered among open grassy areas. A record review by the U.S. Fish and Wildlife Service in a document date March 8, 2019, portrays that the Karner Blue Butterfly should be considered in an effect analysis, but that their records show no critical habitat within the project area. As discussed above, Wild Lupine habitat does not exist on-site. The subject site can be best described as mature deciduous forest with silty/clayey soils onsite. The site does not consist of sandy pine barrens required for the Karner Blue Butterfly. Additionally, no Karner Blue Butterflies or Wild Lupine plants were observed during the time of the field visit. Ingalls&Associates, LLP Civil& Environmental Engineering,Consulting&Surveying Page 1 of 2 ingalls Frosted Elfin (Callophrys irus, Threatened) Frosted are typically found within the northern range of wild lupine habitat. Frosted Elfin primarily utilize Wild Lupine (Lupinus perennis) along with oak savannahs which are often found within sandy pine barrens. Frosted Elfin habitat consist of a patchwork of pine and scrub oak scattered among open grassy areas where were not located at this site. Northern Long-Eared Bat (Myotis septentrionalis, Threatened) Northern Long-Eared Bats hibernate in caves and mines from October through April. Summer foraging habitat typically consists of wooded or semi-wooded upland forests. Maternity colonies are typically within hollow trees or under loose bark of dead or dying trees with exfoliating bark, often exposed to direct sunlight. A record review by the U.S. Fish and Wildlife Service in a document dated March 8, 2019, portrays that the Northern long-eared bat should be considered in an effects analysis, but that their records show no critical habitat within the project area. As there are no mines or caves on the subject site, there is no potential for hibernacula to exist onsite. Typically, maternity colonies are found in the hollows of dead or dying dense hardwood trees; however, colonies do not necessarily select trees by specific species. The site was also reviewed for potential Northern long-eared bat habitat by a qualified biologist, who investigated all trees greater than 3 inches DBH that met the above criteria to determine their suitability to support Northern Long-Eared Bats. Factors such as exfoliating bark, holes, cavities, and crevices were evaluated, and suitable Northern Long- Eared Bat habitat is not likely onsite. Additionally, there are no known maternity roosting trees on the project site or within 150 feet of the site and the project site is not within 0.25 mile radius of a known bat hibernacula. After considerable office and field review of the subject site, it was determined that there was no presence of federally threatened or endangered species onsite.

The subject parcel is 10.3 ± acres and can be identified by tax map ID: 154.00-1-23.1. On September 28, 2018 a qualified environmental biologist from Ingalls and Associates conducted a site walkover to analyze the onsite habitat and survey for individuals of the species listed below. The subject site primarily consists of mature deciduous forest which includes Red Maple (Acer rubrum), Quaking Aspen (Populus tremuloides), and American Hornbeam (Carpinus caroliniana). A review of the subject site concluded that there was no sufficient habitat or presence of the Karner Blue Butterfly (Lycaeides melissa samuelis) and the Northern Long Eared Bat (Myosis septentrionalis). Please find below further details regarding characteristics for suitable habitat for both species mentioned above. Karner Blue Butterfly (Lycaeides melissa samuelis, Endangered) Karner Blue Butterflies are typically found within the northern range of wild lupine habitat. Karner Blue Butterflies primarily utilize Wild Lupine (Lupinus perennis) which are often found within sandy pine barrens. Karner blue butterfly habitat consist of a patchwork of pine and scrub oak scattered among open grassy areas. A record review by the U.S. Fish and Wildlife Service in a document date March 8, 2019, portrays that the Karner Blue Butterfly should be considered in an effect analysis, but that their records show no critical habitat within the project area. As discussed above, Wild Lupine habitat does not exist on-site. The subject site can be best described as mature deciduous forest with silty/clayey soils onsite. The site does not consist of sandy pine barrens required for the Karner Blue Butterfly. Additionally, no Karner Blue Butterflies or Wild Lupine plants were observed during the time of the field visit. Ingalls&Associates, LLP Civil& Environmental Engineering,Consulting&Surveying Page 1 of 2 ingalls Northern Long-Eared Bat (Myotis septentrionalis, Threatened) Northern Long-Eared Bats hibernate in caves and mines from October through April. Summer foraging habitat typically consists of wooded or semi-wooded upland forests. Maternity colonies are typically within hollow trees or under loose bark of dead or dying trees with exfoliating bark, often exposed to direct sunlight. A record review by the U.S. Fish and Wildlife Service in a document dated March 8, 2019, portrays that the Northern long-eared bat should be considered in an effects analysis, but that their records show no critical habitat within the project area. As there are no mines or caves on the subject site, there is no potential for hibernacula to exist onsite. Typically, maternity colonies are found in the hollows of dead or dying dense hardwood trees; however, colonies do not necessarily select trees by specific species. The site was also reviewed for potential Northern long-eared bat habitat by a qualified biologist, who investigated all trees greater than 3 inches DBH that met the above criteria to determine their suitability to support Northern Long-Eared Bats.
