- Alley Light Out Complaint
- Sign Repair Request - All Other Signs
- Sign Repair Request - Stop Sign
- Street Light Out Complaint
- Street Light Pole Damage Complaint
- Traffic Signal Out Complaint
To reproduce these counts against the raw feed

'Alley Light Out Complaint',
'Sign Repair Request - All Other Signs',
'Sign Repair Request - Stop Sign',
'Street Light Out Complaint',

)Analyst tip: Austin splits street lights ('AE Street Light Issue - Address') from traffic signals ('TPW - Traffic Signal - Maintenance') and signs ('TPW - Traffic Sign Maintenance'). Calgary uses the 'Roads -' prefix for all three. Oakland uses the terse 'ELECTRICAL' and 'TRAFFIC_ENGIN' abbreviations.
