According to teir records, te subject property is located witin Pressure Zone. Tis zone as a Hydraulic Grade Line (HGL) of 534. Te site elevations range from 546 to 5 tat correspond to a static pressure of 3 psi and 6 psi. An existing 6-inc water main currently runs witin York Street from te intersection of York St and 52 nd Ave sout along te property frontage. An -inc tap is proposed at te intersection of York St and E. 5 st Avenue into te soutern portion of te project. Additionally tere is an existing 2 water main witin East 52 nd Avenue from te intersection of York St and E 52 nd Ave. Tis project proposes to connect te existing 6- inc water main at te intersection of 52 nd Ave and York St wit a 2-inc water main and extend tat east to te existing 2-inc water main location. Tree new -inc taps are proposed, two at Elizabet St off te new 2-inc water main section and one at Fillmore Street off of te Existing 2-inc water main. All of tese connections are off of Zone Waterlines. (See Appendices B & C) B. Sanitary Sewer Te Eastcreek Farm Subdivision is located in Basin H of te Water and Wastewater Master Plan for te City of Tornton, May 2. Te existing site as no sanitary demand. Te norteast portion of te site will be serviced from an existing 5-inc sanitary main to te norteast of te proposed site. Per an from te City, te 5-inc sanitary main is a dry line (See Appendix D). Te line tat will be tied into tis line from te proposed site is an -inc. Terefore, te existing line as capacity to take on sanitary flow from te proposed site. Te soutwest portion of te site will be serviced by an existing -inc sanitary main in East 52 nd Avenue west of York Street. Te capacity in te existing -inc is.43 cfs and calcuations from te approved 5 t and York Subdivision Utility Report as been included in Appendix D of tis report for reference. Currently it is taking in.6 cfs at its peak, te peak flow tat will enter tis pipe from te proposed site is.2 cfs at peak conditions.
