Culvert Data Issues
• Hand written forms • Outdated • Cumbersome • Current condition • Difficult to prioritize
County designated as MS4 area • Under Phase II EPA NSPDES
• Based on 2000 census data • Expanded Greater Rochester
Area MS4
What to do?
• Large Data Set • Geographically Based • Routine Updating • Accurate Locating • MS4 & Culverts • GIS/GPS
• Geographic Information Systems • Global Positioning System
Planning Department
• Heavily Invested GIS • Extremely Large Data Sets • Integrated planning/tax
data sets • Beta “ONCOR” System
Partnership Planning Department
• GIS complicated • DPW limited GIS experience • Reliance on Planning • Move Forward with GIS/GPS
How do we get there?
• Handwritten Forms converted electronic database
• Manually Plotted Culvert locations in ARCGIS
• Rudimentary Data Set
How do we get there?
• Use GPS for Data Collection • Purchase GPS equipment
• Started with MS4 data • Smaller 22 outfalls • Some outfalls were culverts • Scale up culverts
How do we get there?
• GIS/GPS working for MS4 outfalls • Modify the ARCPAD for Culverts • Scale to 1115 culverts
What data for culverts?
• Inventory Data • Culvert ID # • Year Built • Basic Geometric info • Material • Size
• Large 5’<D/H<20’ • Medium 3’<D/H<5’ • Small D/H<3’
What data for culverts?
• What is Inspected • Roadway Item Elements
• Mainline Pavement • Shoulders • Settlement • Embankment
What data for culverts?
• What is Inspected • Structure Item Elements
• Abutments & Piers • Span Barrel • End Treatments
What data for culverts?
• What is Inspected • Channel Item Elements
• Opening • Alignment • Scour/Erosion • Debris/Vegetation
What data for culverts?
• Weighted Overall Culvert Rating • 10% Roadway Elements • 70% Structure Elements • 20% Channel Elements
Field Inspection-GPS
• For 1115 Culverts • Large, Medium, Small • 8 standard photos
• 2 Highway • Up/Downstream • Inlet/Outlet Ends • Inlet/Outlet Barrel
