Documented CAPEX and funding plan

Plan investment spending and funding over 1 to 30 consecutive years. Reserve deposits are available funding: they are not added to works as a second expense.

Balances are calculated at annual close, without automatic interest or inflation. Additional funding need is the largest closing deficit, not the sum of deficits. No corrective cash injection is assumed. Payment timing within the year may create a larger need.

Enter consecutive years (2000–2099), all nonnegative amounts to the cent and supporting references.
