In the event the local and special assessments originally levied are insufficient for any cause whatsoever, to pay the principal and interest, or the principal or interest, in any one year of the said certificates outstanding at their respective maturity dates, then in this event the municipality or parish issuing such certificates under the provisions of this Chapter, through its governing authority, is hereby authorized, empowered, and obligated by ordinance to levy and collect, at such time or times as may be necessary, an additional local or special assessment on each lot or parcel of real estate in the municipality or parish or area involved, sufficient in amount to pay in full the said principal and interest, or the principal or interest of such certificates at their respective maturity dates.  The amounts assessed in such ordinance or ordinances shall be due and collectible immediately on its passage and if not paid within thirty days from the date of its adoption, the governing authority of the municipality or parish shall proceed against the property for the collection of the amount of the additional local or special assessment so levied, plus interest thereon and ten percent additional for attorneys’ fees.  A certified copy of each ordinance providing for the levy and collection of such additional local or special assessment shall be filed with the clerk of court of the parish in which the municipality or parish is located promptly upon its adoption, who shall forthwith record the same in mortgage records of the parish and when so filed and recorded shall operate as a lien and privilege against all the real estate therein assessed and shall prime all other liens except taxes, and prior recorded local or special assessments levied for streets or gas.
