Per the current General Permit for Construction Discharges SPDES GP-0-20-001, Effective date January 29, 2020 - January 28, 2025, Appendix B, Required SWPPP Components by Project Type, Table 1, "Construction Activities that Require the Preparation of a SWPPP that only includes Erosion and Sediment Controls." The following construction activities that involve soil disturbance of one (1) or more acres of land, but less than five (5) acres: • Single family home not located in one of the watersheds listed in Appendix C or not directly discharging to one of the 303(d) segments listed in Appendix E. • Single family residential subdivisions with 25% or less impervious cover at total site build-out and not located in one of the watersheds listed in Appendix C and not directly discharging to one of the 303(d) segments listed in Appendix E. The project is a residential single family development which will disturb less than an acre (0.30+/- acre) and a full SWPPP is not required. However, this Basic SWPPP is being presented to convey the erosion and sediment control systems that will be employed to manage the site during construction activities. This basic SWPPP is incorporated into the relevant sections of this report. Existing Conditions The subject parcel is rectangular in shape encompassing approximately 0.55 acres in area consisting of woods, grass and brush. The parcel is developed with a 3 story frame dwelling on a portion of the lot that will remain and be known as lot#3. The parcel is bound by Penn Street on the northerly side; Richard Avenue on the easterly side; a residential parcel owned also by Maxine Washington on the southerly side and two residential lots owned by Collingwood on the westerly side. Vegetative Cover Site vegetation consists of woods, lawn grass and brush. Topography The site topography is fairly flat and is at approximately elevation 312 feet. Soils The National Cooperative Soil Survey (NCSS) indicates that the parcel is composed of one type of soil which is identified as Deerfield loamy sand (DeB). Deerfield soils are very deep and moderately well drained. The top layer is typically 25 inches deep being loamy fine sand; the subsoil from 25 to 33 inches is fine sand and from 33 to 60 inches it is sand. Depth to restrictive features is more than 80 inches. Basic SWPPP for 21143 23 Richard Avenue 3 August 2022 COPYRIGHT 2022 ADVANCE ENGINEERING&SURVEYING PLLC ALL RIGHTS RESERVED.

FIGURE-1 I 4 The above-identified soils are further classified by the Soils Conservation Service (SCS) depending on the soils type, into a hydrologic soil group. Depending upon the cover type and the hydrologic condition, the soil groups are assigned curve numbers that represent the storm water runoff condition. The following is a tabular summary of these parameters for the soils component of the project site that will be developed with the proposed residence. Soil Name and Symbol Hydrologic Group Curve Number Deerfield (DeB) A varies Hydraulic Group A/B soils have low runoff potential and high infiltration rates. Hydraulic Group C/D soils have high runoff potential and low infiltration rates. In the dual group soil designation, the first letter is for areas that drain and the second letter are for areas that are undrained. Existing Utilities Water: An 8-inch diameter City of Saratoga Springs Water main exists in the easterly side of Richard Avenue and the north side of Penn Street. Sanitary Sewer: A sanitary sewer system is located at Richard Avenue which can provide municipal service to the new homes. Proposed Development The proposed development consists of subdividing the existing parcel into three lots and constructing three single family homes on the new lots. Project Basic SWPPP Plan Objective The primary objective of the Basic SWPPP is to maintain water quality during the construction phase by implementing Best Management Practices (BMP) that have a proven record of preventing sedimentation associated with construction operations from leaving the project site. The planning of the Basic SWPPP has held as a prime objective the protection of water quality. After development, the surface water leaving the project site will be free of sediments. During construction, the disturbance of the site soils occurring during the construction operations results in altered grades and removal of vegetation which leads to greater runoff velocities and volumes in addition to the generation of sediment and soil erosion as a result from natural occurrences such as rainstorms and winds. These potential impacts are mitigated during the construction phase by ensuring that: A. Erosion and Sediment Controls are in place as a first line of treatment during construction. B. That disturbed areas that advance to final grade are properly seeded in order to establish a vegetative layer, or are stabilized by other means in order to reduce the Erosion and Sediment generation. Basic SWPPP for 21143 23 Richard Avenue 4 August 2022 5 Construction Management Compliance with the City's Grading Permit and the "'New York State Standards and Specifications for Erosion and Sediment Control" requires a program that manages stormwater through ongoing careful review and monitoring of the project site. The narrative, which follows, explains techniques and measures employed to protect water quality during construction. 1. The Contractor will be responsible for: a. Delineating the disturbance limits in the field with erosion control barrier. b. Constructing and maintaining temporary erosion control features. c. Monitoring surface water quality during construction. d. Continual updating of the Basic SWPPP and field erosion control measures. The Owner and principal Contractor will be responsible for informing all other contractors working on the project site of the conditions of the Grading Permit and ensure their compliance with this Basic SWPPP. Construction Sequence Schedule 1. Obtain plan approval and all applicable permits. 2. Flag the work limits and property boundary for protection. 3. Hold pre-construction conference at least one week prior to starting construction with City of Saratoga Springs Stormwater Office Personnel. 4. Install sediment fence as the first construction activity. 5. Complete site clearing. 6. Install construction vehicles access and contractor staging area. 7. Rough grade site, stockpile topsoil, install erosion protection around stockpile, excavate for building foundation and maintain sediment fence as needed. 8. Finish the slopes as soon as rough grading is complete. Leave the surface slightly roughened and vegetate and mulch immediately. 9. Complete final grading and install topsoil in critical areas, and permanently vegetate, landscape, and mulch. 10. All erosion and sediment control practices will be inspected weekly and after rainfall events. Needed repairs will be made immediately. 11. Once minimum of 80% vegetation has been established on the disturbed areas, remove all temporary measures and install permanent vegetation on the disturbed areas. Construction Process and Phasing In order to minimize soil exposure, which affects the magnitude of the erosion and sedimentation potential, the site opened for earthwork operation will be only at those areas scheduled for imminent construction. The entire site will not be exposed and left un-worked. The site work will be divided into a series of phases that will commence with a phase composed of site clearing and will conclude with the seeding operations. During construction operations, the contractor will ensure that critical areas are protected by the guidelines presented herein. Furthermore, these guidelines will be reviewed daily and modifications will be implemented in Basic SWPPP for 21143 23 Richard Avenue 5 August 2022 6 anticipation of predicted weather conditions, soil handling issues, and as determined by the Contractor and reviewed by the Engineer. Management of Construction Debris and Storage of Construction Materials The project site will be managed in a neatly and established manner as discussed during the pre-construction meeting. The Contractor will establish dedicated locations for the storage of construction materials. Construction debris will be actively managed by disposal into dedicated waste containers. Field personnel will be instructed to carry any loose waste materials found and/or generated at the site into the waste containers. The waste containers will be replaced or emptied upon reaching its filling limits. Erosion and Sediment Control Features Erosion and Sediment Control Facilities will be erected at the start of the construction process. While all erosion control measures begin as "temporary", some elements of these features remain in-place long term to continue the protection of the resource adjacent to the development project. The Erosion and Sediment Control Measures to be employed are in accordance with the Best Management Practices as depicted in the manual ' New York State Standards and Specifications for Erosion and Sediment Control" and are as follows: A. Sediment Fence: A sediment fence will be constructed around the topsoil stockpile and along the downstream side of the limits of disturbance to prevent sediment from entering the existing closed drainage system B. Surface Roughening: The 3:1 cut slopes will be lightly roughened by disking just prior to vegetating, and the surface 4 to 6 inches of the 3:1 fill slopes will be left in a loose conditions and grooved on the contour. C. Surface Stabilization:- The project site will rely primarily on vegetative stabilization for the vast majority of those areas susceptible to erosion. Areas that are persistent erosion problems will be specially treated to ameliorate sediment transport and organic soil loss. D. Dust Control: Should excessive dust be generated, it will be controlled by means of a sprinkler system designed to suppress the dust. Erosion and Sediment Control Phasin Phases of Construction Activities Phase of Approximate Construction Description of Area Area (Acres) Basic SWPPP for 21143 23 Richard Avenue 6 August 2022 7 Install silt fence, limits of clearing flagging, construction entrances and staging area; Clear, grub, strip and stockpile topsoil. Perform cuts and fills per Grading Plan; Install driveways; install utilities; install concrete washout area. Construct foundation; frame and complete the 1 homes; Maintain erosion control devices as 0.30 needed. Fine grade and spread topsoil. Seed, mulch and water as needed. Reseed areas that have not achieved 80% growth, mow and water lawn areas, reseed bare areas as required. Perform site clean-up, remove erosion control devices, mow lawn areas as required Total Area of 0.30 +/- NA Disturbance Note: All idle areas of the site shall receive a minimum of 4-inches topsoil, seed & mulch. At no time shall disturbance to the site exceed 0.30 acres. Contractor shall water, mow and re-seed disturbed areas as required throughout the duration of the project. Erosion and Sediment Maintenance The following set of review guidance and criteria will be employed during erosion and sediment control maintenance. The supervision of this program in the field shall be performed by the Contractor: A. All erosion and sediment control practices will be checked for stability and operation following every runoff-producing rainfall but in no case less than once every week. Any needed repairs will be made immediately to maintain all practices as designed. B. Sediment will be removed from the sediment fence when it becomes about 9-inches deep at the fence. The sediment fence will be repaired as necessary to maintain its intended function. C. All seeded areas will be fertilized, re-seeded as necessary and mulched according to specifications in the vegetative plan to maintain a vigorous, dense vegetative cover. SUMMARY This Report has presented the basic SWPPP that will be implemented at the project site to prevent and control the generation of erosion and sediments associated with the disturbance of ground surfaces during the construction process. As previously mentioned the project is a residential development with less than 1 acre of disturbance that only requires the SWPPP to include erosion and sediment control plan.
