9. The existing and proposed structures will be shown on plans and profiles appearing in Drawing Nos. C-11 and S-28. 10. On Drawing Nos. C-12, C-13 and C-13A, the 12" storm sewers shown at track level were part of the original railroad drainage system installed at time of railroad construction. n. Structural computations signed and sealed by a N.Y.S.P.E. will be submitted for the flow distribution maintenance, flow adaptor and flow redirection chambers will be submitted. Hydraulic design of the connection piece between the flow adaptor chamber and manhole No. 2 is based on chamber design examples provided by the Bureau of Sewers (See Attachment). The "90° BEND" labeling shown on Drawing No. S-28 is incorrect and will be changed to read "FLOW REDIRECTION CHAMBER". Manholes Nos. 1, 2 and 3 are not standard manholes therefore their design details are shown on Drawing No. 30A. Information regarding type of catch basins and proposed 15 inch diameter sewer will be added to Drawing No. S-28. 12. Deflection angles and radii, where required, are shown on Drawings Nos. S-30 and S-30A. 13. A note will be added at the location of each abandoned sewer shown on Drawing No. S-28. This note will read: "NO HOUSE CONNECTIONS ARE LOCATED WITHIN THESE LIMITS" (of abandonment). 14. Drawing No. C-21 will be submitted as part of contract drawings. 15. Because of multi-disciplinary requirements of this project, the N.Y.C. standard details for catch basin type 3, etc. have been included for contractor's guidance, as shown on drawing Nos. C-19 and C-20.
