Three kilometres of new forest road, 5 m wide, USD 80,000 budget.
It must open before the rains, and only one item can be done first.
Side drains or gravel first: which drives later maintenance cost more?

Drainage first: without side drains and culverts, the gravel layer is destroyed by pumping within a season.

We build slope and drains first, then grade the surface and add more next year; costs stay controlled.

Size culverts by catchment area; one blocked crossing washes out the whole section. That detail matters most.
