California Code, Harbors and Navigation Code - HNC § 3911

In determining the dates of maturity of the bonds, and the amount thereof to mature at each date of maturity, the committee shall be guided, so far as it may deem to be practicable, by the amounts of the revenue estimated to accrue to the Harbor Bond Sinking Fund. The committee shall fix and determine the dates and amounts of such maturities in such manner that, together with the dates and amounts of interest payments on the bonds, they shall coincide, as nearly as it may deem to be practicable, with the dates and amounts of such estimated revenue.
