Introduction
Existing Culvert Data GIS Culvert Program Applications
Ontario County DPW • 243 Miles of Roads
• 75 Bridges • 1115 Culverts
Culvert Data Issues
• Hand written forms
Culvert Data Issues
• Hand written forms
Culvert Data Issues
• Hand written forms • Outdated • Cumbersome • Current condition • Difficult to prioritize
County designated with MS4 area
• What is MS4? • Municipal • Storm • Separate • Sewer • System
County designated as MS4 area • Under Phase II EPA NSPDES
• Based on 2000 census data • Expanded Greater Rochester
Area MS4
Rochester MS4 boundary
MS4 Data Issues
• Required MS4 Program Development • Document/Inspect • Storm Water Outfalls
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
Decided to use GIS
• Expansion of data sets • Signs • Guiderail • Sanitary Sewer
Partnership Planning Department
• GIS complicated • DPW limited GIS experience • Reliance on Planning • Move Forward with GIS/GPS
