3. SWQDC
Storm Water Quality Data Conversion (SWQDC)
Multi-year effort led by CCH HOLIS to improve the coverage, accuracy, and
·
dissemination of CCH storm water-related GIS data
· National Pollutant Discharge Elimination System (NPDES) permit
· CCH ENV, DPP/HOLIS, DDC, and DFM
· Identify and collect potential data sources
· Design and populate new storm water geodatabase
· Design and build Geometric Network
· Design and develop web-based mapping application
· Establish long-term maintenance procedures

4. Geodatabase
Storm Water Geodatabase
· Data sources
· ~8,000 1995-2006 as-built plans
~15 other types, ranging from historical hand-drawn drainage maps to field data
·
collection
· Georeferencing
· Heads-up digitizing
· Sewing together patch-work file geodatabases
· Large QA/QC effort: spatial and attribute data accuracy
· Feature counts:
· ~65,000 structures
· ~62,000 conduits = 1,040 miles
· Production of a complimentary project plans database
· Almost 70,000 plan records

5. Geometric Network
Storm Water Geometric Network
· ArcGIS Geometric Network
· Declaration of Sources and Sinks
· Simple Edges
· Stand alone, heavy topology; goal: no Orphan Junctions
· Overall goal: determinate flow in all conduits island-wide
· Integration of State DOT and NAVFAC storm water datasets
· Differences in State DOT geometric network design
· Overlap between State DOT and CCH data
· Modeling the real world and creation of "virtual" network feature classes

7. An Example
A Recent User Case
· ENV notified of a spill plume in Kakaako/Kewalo Basin outfall
· ENV request to HOLIS to trace upstream from outfall to identify potential spill sources
· Map production with upstream trace and georeferenced construction plans

8. Technical Architecture
Under the SWAPP's Hood
· Custom ArcGIS Server (v10.0) Web ADF design
· Local Web ADF-to-ArcGIS Server connection
· ArcSDE GIS data repository
· SQL Server non-spatial business data repository
· Programmed in ASP.NET/VB.NET
· Leverages AJAX Partial Post-back lifecycle model
· Custom ArcObjects modules
· JavaScripted dynamic HTML in user interface
· Conserve screen real estate
· Avoid pop-up windows
· XML configuration file

9. Deployment
ArcGIS Online
www.arcgisonline.com
Rolling Out the SWAPP
· Multiple demonstrations during and after development
· Pre-deployment host scenario definition
· Initial deployment in March and April 2011
· Post-deployment testing
· First "Service Pack" applied September 2011
· Storm Water GIS on ArcGIS Online in Fall of 2011
· New Report Generator tool scheduled deployment Spring 2012

10. Lessons
Lessons Learned
· Reinforcement of the user-first strategy
· Identification of data sources
· Importance of field-based feedback, notification, and recognition
· Strong feature identification protocol
· Web ADF deprecation

11. Improvements
Improving the SWAPP in the Future
· Further integration of NPDES business data
· NPDES data clearninghouse
· NPDES report generation
· Opening to CCH NPDES contractors
· Update functionality, especially field-based corrections
· Resolve Web ADF dependence
