These needs may include removal of silt, litter and other debris from all catch basins, inlets, ponds and detention! retention basins, outlet structures and drainage pipes, grass cutting and vegetation removal, and necessary replacement of landscape vegetation. Any maintenance needs found by city inspection or otherwise must be addressed in a timely manner, as determined in writing by the Director. The inspection and maintenance requirement may be increased as deemed necessary to ensure proper functioning of the permanent BMPs. (2) Inspection programs may be established by by the city on any reasonable basis, including but not limited to: routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; inspection of drainage basins or areas identified as higher than typical sources of sediment or other contaminants or pollutants; inspections of businesses or industries of a type associated with higher than usual discharges of contaminants or pollutants or with discharges of a type which are more likely than the typical discharge to cause violations of state or federal water or sediment quality standards or the COPS stormwater permit; and joint inspections with other agencies inspecting under environmental or safety laws. Inspections may include, but are not limited to reviewing maintenance and repair records; sampling discharges, 13 surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater treatment practices. (3) When any permanent BMP is installed on private property, or when any new connection is made between private property and a public drainage control system, the property owner shall grant to the city the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection. This includes the right to enter a property when the city has a reasonable basis to believe that a violation of this chapter is occurring or has occurred, and to enter when necessary for abatement of a public nuisance or correction of a violation of this chapter. (4) Parties responsible for the operation and maintenance of a permanent BM P shall make records of its installation and of all maintenance and repairs, and shall retain the records for at least 2 years. These records shall be made available to the city during inspection of the facility and at other reasonable times upon request. Sec. 20-35. Financial security.

(b) A further condition of the grading permit required by section 20-31 and/or section 26-623 of this Code shall be the posting of a performance bond to guarantee the construction of the BMPs or stormwater facilities required by this chapter, as fully set forth herein. (c) The amount of the performance bond shall be based upon an itemized cost estimate prepared by the permittee and approved by the city. (d) Form of performance bond WRPWQ13 (1) The performance bond shall be for one hundred twenty-five (125) percent of the estimated costs of the required grading and BMP improvements as computed by the permittee and approved by the Director. The requirement for a performance bond under chapter 26, section 623 of this Code may be satisfied by inclusion in the performance bond required in this section. Submittal of more than one (1) bond is not required. (2) No form of performance bond drawn upon a bank or financial institution having any relationship to the applicant or any principal, director, officer or shareholder of the applicant (other than the relationship of depositor or checking account holder), shall be acceptable. The city may reject any tendered performance bond for any reason. 14 (3) The performance bond shall be in a form satisfactory to the city attorney. The performance bond guarantees the city that the financial backing is available and the improvements will in fact be completed and paid for. a. The performance bond may be from any financially responsible lender that is not directly or indirectly owned or controlled by the permittee. b. The performance bond shall be in effect for a minimum period of one (1) year and shall be renewable for subsequent oneyear periods at the city's sole discretion. c. The performance bond shall be such that the city is assured that the permittee has funds committed to the amount and that in the event of a default by the permittee the city shall have available to it, upon demand or, funds necessary to construct any/or all of the grading and BMP improvements. d. The city may release percent portions of the performance bond in increments of no less than twenty-five (25) at the discretion of the Director upon written request of the applicant. In such case, an amended performance bond shall be required. In no case shall the full amount of the performance bond be released until final acceptance has been granted and all BMP improvements have been constructed and approved. e. After all repairs are made at the end of the warranty period and final acceptance is issued, the performance bond will be released. (e) If the permittee does not successfully complete all required work or violates any requirement of the permit or this chapter, the city may take corrective measures and charge the cost of such to the permittee. Such costs shall include the actual cost of any work deemed necessary by the city plus reasonable administrative and inspection costs and penalties pursuant to this Code. If the total of such costs exceeds the performance bond, the permittee shall be responsible for payment of the remaining balance within thirty (30) calendar days of receipt of an accounting of such from the city. Such costs, if unpaid, may be certified to the county treasurer for collection in the same manner as real property taxes. Sec. 20-36 -20-40. Reserved. WRPW013 15 ARTICLE IV. ENFORCEMENT Sec. 20-41.
