The City Manager wants to talk
about…

BMP Database• Streamline the process
When did we last inspect this BMP?
Why are we filling out the same information
three times?
Have you seen my inspection report?
Have all of the NOVs been addressed?
What inspections are due this month?
Mobile BMP Inspect ion App
Nine forms converted to nine services
New record created each t ime an inspect ion is
completed
Mobile BMP Inspect ion App
Link mult iple inspect ions using unique ID
Future inspect ions will be pre-populated with
previous inspect ion’s data
BMP Database• Stormwater BMP Database
• Consolidated data into a single database• Inspect ions viewed by
