Additional Work to be completed •Review / Verify Parameters Review land use areas with cities Review coefficients with District engineers Review choice of modeled pipes with District engineers Identify additional pipes to model Perform flow metering to verify flow at selected nodes 5/7/2014 7
Additional Work to be completed •Analyze Results Identify pipes that require additional capacity Develop schedule for improvements Develop budget for improvements Determine potential effects on pumping stations 5/7/2014 8
Additional Work to be completed •Publish Results Prepare a narrative for each section in the report Publish a formal master plan report 5/7/2014 9
Conclusions •Sewer Master Plans are typically updated every 5 -15 years. 2015 will be the 10 -year mark. •GIS format facilitates easy testing of various land use scenarios. •Substantial development is currently occurring in Costa Mesa and Newport Beach and land use changes are being considered. •A Sewer Master Plan is required under the Waste Discharge Requirements (referred to as “capacity assurance”). 5/7/2014 10
