Wyo. Stat. § 15-6-437
If the governing body determines that improvements constructed in any local improvement district confer general benefits on the city or town, it may create concurrently a fund to be known as the revolving local improvement fund. In payment for those benefits and to meet the financial requirements of the revolving fund, the city or town shall advance annually to the credit of the fund from the proceeds of city or state gasoline or state cigarette license taxes collected or received by it, a sum of not less than two percent (2%) of the total amount of the bonds issued for the local improvement district for a period of ten (10) years or for the length of time necessary to pay all bonds issued, whichever is the shorter. The fund shall not exceed twenty percent (20%) of the outstanding bond obligations of the district.
