Stormwater Pollution Prevention Plan General Overview: Total Land Disturbances = 0.37 acres Per Article 17 of the UDO – Section 17.4.A – This project is required to prepare a stormwater pollution prevention plan (SWPPP). However, under the requirements of Section 17.4.A.3, only a Basic SWPPP is required for   nonresidential and mixed-use development disturbing between 0.25 acre and 0.49 acre. The provided SWPPP meets the requirements for a Basic SWPPP as described in UDO Section 17.5.A Basic SWPPP. It should be noted that some of the analysis and documents provided in the SWPPP go beyond the requirements set forth in UDO Section 17.5.A Basic SWPPP; however, the SWPPP was still evaluated for overall merit and technical content. 13. Page 6 – Section 2.4 – Add description about perpetual easement area. A description of the perpetual easement has been added to Section 2.4 of the SWPPP. 14. Page 7 – Section 3.2 – Add Article 17 of the UDO to the stormwater design standard. Reference to Article 17 of the UDO has been added to Section 3.2 of the SWPPP. 15. Page 8 – Section 4.1 – Add concrete washout description. A concrete washout description has been added as Section 4.1.11 – Concrete Truck Washout. 16. Section 6.3 – Construction Inspection Checklist a. Remove the following DEC inspection checklists as they are not relevant to project: Stormwater/Wetland Pond, Infiltration Basin, Sand/Organic Filter, Bioretention, and Open Channel. The listed checklists have been removed from the SWPPP. b. Include technical operations information and/or owners’ maintenance manual for catch basins, WQ Unit and Open-Bottom Detention System. The Long-Term Operations & Maintenance Manual has been added to Section 6.3 of the SWPPP. SWPPP Appendix - Project Narrative & Stormwater Report 17. Page 4 – Site Characteristics – The existing site is only 0.32 acres (or 13,939 sq ft), not 15,778 sq ft. According to Sheet S-1, some areas within the property boundary are vegetated, so not all 13,939 sq ft should be considered impervious. The Site Characteristics section has been revised to reflect the correct area of impervious surface on- site. 18. Page 5 – Zoning Assessment – Revise year of Zoning Map because UDO provides a 2023 Zoning Map. Project Narrative has been revised to reflect a 2023 date for the UDO Zoning Map. 19. Page 5/6 – Table 1/2 – Zoning District Dimensional Standards a. Revise minimum setback requirement for right-of-way greater than 40 feet.   Table 1 has been revised per comment. b. Minimum Build Out percentage does not match percentages on Sheet 2.11. Tables have been revised per comment. 20. Page 5 – Project Description – Describe the area that is included in the perpetual easement, include site information, such as current property owner, existing land use, easement area, etc. A description of the perpetual easement area has been added to the Project Narrative. 21. Page 7 – Stormwater Management a. There are two Stormwater Management sections (Pages 7 and 9). Consolidate into one. The Stormwater Management sections have been consolidated per comment. b. Add that project is designed to also conform to Article 17 of Saratoga Springs UDO. Reference to Article 17 of the UDO has been provided in the Stormwater Management & Soil Erosion Control section of the Project Narrative. 22. Page 9 – Time of Concentration – Provide explanation for using minimum time of concentration. No calculations/descriptions are included in Appendix C as stated. According to the SCS / NRCS – TR-55 methodology for stormwater runoff analysis, the minimum time of concentration used shall be 0.1 hour (6 minutes). Calculations performed by Solli yielded a value less than the minimum time concentration, therefore the minimum time was used. 23. Page 10 – Existing Conditions – Add information for contributing drainage area that is included in perpetual easement. The contributing drainage areas have been revised to include the perpetual easement area for both existing and proposed conditions. 24. Page 13 – Underground Detention System a. Provide description of underground detention system (i.e., brand, size, outlets, infiltration rates, etc.). Additional information on the underground detention system has been added in the Hydraulics – Proposed Condition section of the Project Narrative. b. Per NYSDEC SWMDM, all proposed infiltration techniques require soil infiltration testing.   An outlet control riser is proposed within the underground system. A 4” orifice is proposed at the bottom of stone elevation (312.30’), therefore no wet storage below a low-flow orifice will be provided, as it is not the invention for this system to be used for infiltration purposes. 25. Page 13 – Water Quality a. Narrative and Detail on Sheet 3.02 show 1-foot-deep sump. However, note #11 on Sheet 2.21 says 2-foot sump. Note #11 has been revised as all catch basins will require 1-foot minimum sumps. b. Double check the statement “reduces the existing impervious cover of the project area by approximately 15.2%” to ensure it includes the area that is within the perpetual easement. The statement has been revised based on the changes to the contributing drainage areas. 26. Page 13 – Soil Erosion & Sediment Control – Include concrete washout description. Concrete truck washout has been added to the list of proposed erosion and sediment control measures per comment. 27. Appendix C – HydroCAD results a. Expand time span further than 20 hours to have runoff depth be equal to a depth rather than greater than. HydroCAD report has been revised per comment. b. Provide infiltration testing results to justify the 0.17 in/hr exfiltration rate. The exfiltration rate has been removed from the analysis, as the low-flow orifice is located at the bottom of the system and therefore does not take infiltration into account. 28. Appendix D – Existing Drainage Area Map (DA-1) – Show contributing drainage area for area of perpetual easement. The contributing drainage areas have been revised to include the perpetual easement area for both existing and proposed conditions.   Sincerely, Solli Engineering, LLC Casey J.
