OK, let's see...
We get 3.8 BP from taxes for the city to spend, plus we still have two Building Beans which can count as 0.5BP each toward separate projects.
Paved streets in Central costs 2BP, gives +2 Loyalty and +2 Stability.
Port Henry still lacks a District Wall, which would cost 1BP, gives +1 Loyalty and +1 Stability.
Clearing the land for each new district to be added to the city costs 1BP per district. Expanding the city from current 3 districts to 4 districts would take us up from Large Town to Small City status and increase Base Limit from 2,000gp to 4,000gp and Purchase Limit from 10,000gp to 25,000gp, which is good for adventurers returning with loot to sell and wanting to buy magic items in the city.
We should definitely open up at least one new district.
I favour the idea of increasing defence as well, because Tusk could potentially be attacked by the River Kingdoms sometime in the future. I would suggest expanding the City's Small Wall to include the new district 4 (if we go that way). Previously, "Building a Small wall around two districts will cost 4bp - around three will cost 5 bp", so presumably expanding the Small Wall around another District costs another 1BP and adds +1 Defence (I think).
Adoven's proposed upgrade from jetty to pier would cost him 1BP and add +1 Economy.
Perhaps we should ask for 0.5BP contribution from Adoven toward the cost of a District Wall for Port Henry for permission to upgrade to Pier? If he doesn't have that 0.5BP now it could be a contribution paid next Kingdom round instead.
So what might that add up to?
- 2BP Paved streets in Central
- 1BP District wall in Port Henry
- 1BP new district 4
- 1BP extend Small Wall around new district 4
- Total cost 5BP
We have 3.8 BP (taxes) +1 BP (building beans) +0.5 BP? (Adoven, now or next round?).
We might have to borrow from somewhere else if Adoven can't contribute straight away.
Pipre's plans (whatever they are) might still change things, too.
It has also been suggested that we could add the position of Marshal on the City Council. I would certainly support the suggestion of someone (of Lawful Good alignment) from the Church of Iomedae in that role, as the stronghold stewardship rules would then allow us a bit more variance in the Economy/Stability/Loyalty values of the city.
