Black Soil - Production is now regular and huge amounts of trash are turned to black soil every year, but there's always room for more production [Gardeners] [King]
Build Wall - Long experience with retaining walls has lead to the idea of a settlement wall for protection (Coastal village completed)
Build War Wagons - Increasing the number of war wagons would increase the general strategic and battlefield mobility of forces, although would be expensive to do so
Establish Annual Festival - People already like to celebrate at certain times of the year, but with the level of control over food distribution a new and particularly lavish festival can be established
Expand Farms - The people have brought an enormous amount of land under cultivation in the valley, but there is more available in more marginal areas, and in the forests around the fishing village
Expand Fishing - There are managed cultivation zones along the shore, and dedicating more people to the tasks can increase the yields of fish and luxuries brought in
Expand Managed Forests - There are many forests throughout the hills about the various forests that could be brought under proper management
Expand Pasture - While the traders mostly just take their animals where there is good grazing, specific areas can be set aside around the settlements that can be made ideal for the protected grazing of herds
Expand Place to Spirits - The current place dedicated to the spirits and wisdom is nice, but it could be bigger and grander...
Expand Snail Cultivation - While now more reliably grown and harvested, the snail domestication has only managed to hold environmental changes at bay rather than increase production. More investment would increase cultivation
Expand Warriors - More men can be inducted into the ranks of the warriors every year and not face major food shortfalls
New Settlement - The land is not particularly good for farming in between the valley and the sea, but there are places where a settlement could be set up, serving as a stop over point along the journey between the two settlements
New Trails - The settlements in the valley and the coast are well tied together, but there are new contacts to the north who could be better tied together
Step-Farms - Step farms have been established and have grown across the valley, but there are still plenty of hills to resculpt [Gardeners][King]
Trade Mission - Sending a major caravan to another large group can bring new opportunities and find out more about the outside world
War Mission - You can send raiding parties against groups that have declared themselves hostile
Mega-Projects - Mega-Projects can require many generations to complete, take an unknown amount of time to do so, and drain Econ while active, but can produce massive benefits once complete. Once chosen, the occupy the Main Focus slot until either completed or stopped early. Early stopping once started does not refund any of the investments and increases social strife. To reduce confusion, mega-projects are not listed as part of the voting project list and must be "written-in".
Fight Forest Blight - Something is going wrong in a number of wild forests, and generations of intervention may be required to stop it [Gardeners][King] (Active)
Grand Canal - The hills between the valley and the sea are rough and the rivers there fast and wild. In one man's dream there is the vision of an artificial river cut through the land, tame and managed [Gardeners][King]
Great Dam - The river can run wild and dangerous when the rains come strong, but could it not be controlled by the same principles by which the water on the hills is channelled and contained, merely on a larger scale? [Gardeners][King]
