A. 
Any development or redevelopment of one (1) acre or more shall comply with the following requirements:
1. 
An enforceable maintenance agreement shall be executed that designates the parties responsible for the operation, maintenance and repair of all stormwater management facilities and any other system, structure or measure required by this Chapter. The agreement shall include provisions for funding all required maintenance.
2. 
All maintenance agreements shall be approved by the City and by MSD. The maintenance agreement executed with MSD shall be recorded with the St. Louis County Recorder of Deeds in accordance with MSD requirements.
3. 
A maintenance covenant, approved by the City and recorded with the St. Louis County Recorder prior to final plan approval, shall be entered into to insure maintenance of all stormwater facilities in the development or redevelopment. As part of the covenant, a schedule shall be developed for when and how often maintenance will occur to insure proper function of the stormwater management facility. The covenant shall also include plans for periodic inspection to ensure proper performance of the facility between scheduled inspections and service.
4. 
All stormwater management facilities shall undergo, at a minimum, an annual inspection to document maintenance and repair needs and insure compliance with the requirements of this Chapter and accomplishment of its purposes. These needs include removal of silt, litter and other debris from all catch basins, inlets and drainage pipes, grass cutting and vegetation removal, and necessary replacement of landscape vegetation. All maintenance needs found shall be addressed in a timely manner.
5. 
All developers must execute an easement and an inspection and maintenance agreement binding on all subsequent owners of the real estate served by on-site stormwater management measures and such shall be recorded with the St. Louis County Recorder of Deeds.
6. 
The design and planning of all stormwater management facilities shall include detailed maintenance and repair procedures to insure their continued function. These plans shall identify the parts or components of a stormwater management facility that need to be maintained and the equipment and skills or training necessary to do so. Provisions for the periodic review and evaluation of the effectiveness of the maintenance program and the need for revisions or additional maintenance procedures shall be included in the plan.
7. 
Parties responsible for the operation and maintenance of a stormwater management facility shall make and maintain records of the installation (as-built drawings) and of all maintenance and repairs and shall retain the records for a period of not less than five (5) years. Such records shall be made available to the City during inspection of the facilities and at other reasonable times, upon request. Copies of the as-built drawings shall be submitted to the City, as well as any drawings that show substantial repair or modifications to the facilities.
8. 
The developer or redeveloper shall establish a landscaping plan which provides for the maintenance of vegetation at the site after construction is completed, including who will be responsible for the maintenance of vegetation at the site and what practices will be employed to ensure that adequate vegetative cover is preserved.
9. 
All developers and redevelopers must prepare and implement an erosion and sediment control plan for all construction activities related to implementing any on-site stormwater management practices.
