The OOC room
The Constabulary is in O-15. It is the tip of the odd projection of the Municiparia that extends towards the harbor. The Constabulary is across the street from the Harbor Market, which is a roughly U shaped collection of small shops and food stalls facing a little plaza- a sort of strip mall.
There will be more on this shortly, but for now...
Close by at the Harbor to the west (left) there is the Watermens' Slip, which is the central hub for the city's floating taxi service, and the Constables' Slip, which has the Constables' Boat and room for any boats you might have to impound.
Your neighbors to the east (right) are an ice house (not everything in the Municiparia district is a government building, these people get in loads of ice from barges that come down the river, store it, and resell it in warm months) and the Pomton Street Repair Office, which is mostly storage for roadway repair materials and a mustering point for the crews. The poor of the city are required to perform service for a month a year in lieu of paying taxes, and some are put to work repairing the roads.
