• 2 separate models with free outfalls Onondaga
Lake
• HBIS: 3 pump stations (PS)
• MIS: 1 PS, 1 RTF and EBSS gates
• Not geo‐referenced
• Used SWMM default infiltration parameters
• Imperviousness obtained by visual interpretation of aerial photos HBIS
• Simplified wet weather operation controls
MIS
• Model network vs GIS trunk sewer alignments (shown as background)
Recap Model Development and Calibration
Updated Model Network – 2012/2013
• One combined model with 3/18/14
46
refined boundary conditions (Metro Headworks)
Onondaga
Lake
• 1,807 vs. 503 nodes; 1,909 vs. 577 conduits; and 456 vs. 94 subcatchments
• HBIS: 3 pump stations (PS)
• MIS: 4 PS, 2 RTFs and modified EBSS gates
• Geo‐referenced
• Used USDA soil survey data
HBIS
• Imperviousness based on Syracuse aerial survey GIS land cover and supplemented with Landsat imagery MIS

Advantages of Revised Program
• Balanced approach: Gray & Green
• Improved water quality for tributaries and lake
• Gray:
• Fixed capture benefit
• Depreciates over time
• Green:
• Can appreciate over time
• Ancillary environmental and community benefits
• Onondaga County at the forefront of GI Movement
• Philadelphia, PA
• Portland, OR
• Cincinnati, OH
