It shall be unlawful for the owner or developer, their successors or assigns, to allow the streets within their development encompassed by Section 4-6.501(a) to fall into a state of disrepair which would render said street or streets unacceptable if offered for public use.

(§ 1, Ord. 1054, eff. March 31, 1971, as amended by § 19, Ord. 1143, eff. August 30, 1972)
A violation of §4-6.502 shall be a nuisance and the Chief of Code Enforcement shall abate said nuisance as follows:
a. 
Notice to Repair. The Chief of Code Enforcement is authorized by this article and empowered to notify the owner, developer, their successors or assigns of a violation of Section 4-6.502 and order immediate repair to any defective street or streets which is sufficient to return said street or streets to the condition required by this article. Written notice shall be by registered mail addressed to the owner, developer, their successors or assigns at the last known address.
b. 
Action upon Noncompliance. Upon the failure, neglect or refusal by the aforementioned party or parties to make the required repairs within a reasonable time after receipt of said notice, the Chief of Code Enforcement is authorized and empowered to cause the required repairs to be made. In the event the written notice is returned to the post office because of its inability to make delivery thereof, the Chief of Code Enforcement shall immediately cause a notice to be posted on the property concerned, and upon failure, neglect or refusal of the owner, developer, successors or their assigns of the property in question to properly restore the defective road or roads within thirty (30) days after the return of the notice to the post office, the Chief of Code Enforcement is hereby authorized and empowered to order the repairs to be made.
c. 
Charge Included in Tax Bill. When the City has effected the repair of the defective road or roads or has paid for their repair, the actual cost thereof, plus accrued interest at the rate of seven percent (7%) per annum from the date of completion of the work, if not paid by such owner prior thereto, shall be charged to the owner, developer, their successors or assigns on the next regular tax bill forwarded to such owner by the City and such charge shall be due and payable at the time of payment of such bill.
d. 
Recorded Statement Constitutes Lien. Where the full amount due the City is not paid within sixty (60) days after the repairs are made, the Chief of Code Enforcement shall cause to be recorded in the office of the City Clerk a sworn statement showing the cost and expense incurred for the work, the date the work was done and the location of the property on which the work was done. The recordation of such sworn statement shall constitute a lien and privilege on the property and shall remain in full force and effect for the amount due in principal and interest, plus costs of court, if any, for collection until final payment has been made. Such costs and expenses shall be collected in the manner fixed by law for the collection of taxes and shall be subject to a delinquent penalty of $5.00 in the event the same is not paid in full on or before the date the tax bill upon which such charge appears becomes delinquent. Such sworn statements shall be prima facie evidence that all legal formalities have been complied with and that the work has been done properly and satisfactorily and shall be full notice to every person concerned that the amount of the statement, plus interest at the rate of seven percent (7%) per annum from the date of completion of the work, constitutes a charge against the property designated or described in the statement and that the same is due and collectible as provided by law.
