The Subdivision Plat must be signed/sealed by the licensed land surveyor. 7. Please label on the Subdivision Plat the minimum permeable area required as well as the maximum impermeable area allowed for each lot. 8. The name of the property owner should be added to the title block of the drawings. 9. In accordance with City subdivision requirements for Conservation Subdivisions, preserved open space land shall be clearly delineated and labeled on the subdivision plat as to its use, ownership, management, method or preservation, and the rights, if any, of the owners of lots in the subdivision and the public to the open space land. The plat shall clearly show that the open space land is permanently preserved by a conservation easement and include deed recording information in the County Clerk's office for the conservation easement. 10. The deed restricted area shown on the subdivision plat should not include the driveways to each home. The Subdivision Plat should be updated to reflect this and quantify the total area of deed- restricted open space on each lot. 11. In accordance with City subdivision requirements (City Code Chapter 241, Appendix H —General Requirements and Subdivision Design Standards, Section 2-R), all applicants for proposed subdivisions are to offer the City 10%Class A Type Usable Land, or an acceptable alternative defined in the City Louden Road Residential Conservation Subdivision—PB19.004—15t Submittal Review February 7,2020 Page 3 of 4 Code. The plans do not indicate any land that has been offered to the City. Please identify how the code requirement will be met. 12. Proposed grading shall be further refined to depict how surface runoff will be directed around proposed homes and absorption fields. Additional spot grades may be necessary to clarify this. 13.

Please revise accordingly. 14. Insufficient information and detail are provided for the proposed septic tank and onsite disposal system to verify compliance with NYSDOH requirements presented in "Residential Onsite Wastewater Treatment Systems Design Handbook". Specifically, please show the following: a. NYSDOH regulations state 2 percolation tests must be performed within the limits of each proposed absorption field. The only lot that has a percolation test within the absorption field is lot 5, and there is only 1. Additional testing is required in accordance with NYSDOH requirements. b. The proposed septic system layout, showing the laterals, expansion area, septic tank and distribution box locations for each lot. c. Proposed invert elevations of all system components along with top of concrete and the finished grades over each component. d. Certification and tightness testing requirements. e.

Please revise accordingly. 15. Please show the location of the water service connections and shutoff valves from each of the proposed wells to the house on the Development Plan and indicate size and material of the service. 16.
