III. BMP Maintenance Information
Purpose and Specific Narrative
Urban Stormwater runoff contains many types and forms of pollutants. When
compared to stormwater run-off from pre-developed conditions, high
concentrations and some contaminates that are not naturally present in
surface runoff from undeveloped local lands are found. Runoff from
undeveloped watersheds contains sediment particles, oxygen-demanding
compounds, nutrients, metals, and other constituents. Once developed,
constituent loads increase because surface runoff volumes increase and the
sources of many of these pollutants also increase. Supplemental applications
of compounds, such as fertilizers, also tend to increase the availability of
some pollutants to stormwater runoff.
Best management practices (BMP’s), both structural and non-structural, can
reduce the pollutants in stormwater. The BMPs proposed for this
development are an infiltration basin and a woodland preservation area.
An infiltration basin is a surface pond which captures first-flush stormwater
and treats it by allowing it to percolate into the ground and through permeable
soils. As the stormwater percolates into the ground, physical, chemical, and
biological processes occur which remove both sediments and soluble
pollutants. Pollutants are trapped in the upper layers of the soil, and the water
is then released to groundwater.
Inspections
Responsibilities:
Stormwater quality facilities shall be maintained in good condition, in accordance
with the Operation and Maintenance procedures and schedules listed in the
Indiana Stormwater Quality Manual or the City of Carmel Stormwater Technical
Standards Manual, and the terms and conditions of the approved stormwater
permit, and shall not be subsequently altered, revised, or replaced except in
accordance with the approved stormwater permit, or in accordance with
approved amendments or revisions in the permit. Following construction
completion, inspection and maintenance of stormwater quality facilities shall be
the long-term responsibility of the Owner.
The City of Carmel Engineering department has the authority to perform long-
term, post-construction inspection of all public or privately owned stormwater
quality facilities. The inspections will follow the Operation and Maintenance
procedures included in the City of Carmel Stormwater Technical Standards
Manual and/or permit application for each specific BMP. The inspection will
cover physical conditions, available water quality storage capacity and the
operational condition of key facility elements. Noted deficiencies and
recommended corrective action will be included in an inspection report.
The Owner shall submit an annual BMP Maintenance Report to the City of
Carmel Engineering Department; The first report is due one year after
construction is completed, with subsequent reports due each year within the
same month of the initial report. If there are any deficiencies found during the
inspections, these should be addressed. If the inspection report is not received
within the month it is due, if there are deficiencies which were not included in the
report, or if any deficiencies included in the report are not addressed in a timely
manner, the BMP owner faces enforcement action from the City. This report
should be submitted to:
Carmel Engineering Department

Maintenance
Responsibilities:
Routine Maintenance:
The BMP owner will also be required to perform any maintenance specified at the
City’s discretion. The following criteria shall be considered the minimum routine
maintenance to be performed:
