[Ord. No. 08-1852 §1, 2-19-2008]
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.
