City of Carmel

The City of Carmel, Indiana has enacted a Stormwater Ordinance in order to provide for the health, safety, and general welfare of the citizens of the City of Carmel through the regulation of stormwater discharges to the maximum extent practicable as required by federal and state law. The City of Carmel is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Carmel will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. Stormwater fees will be calculated and collected by the city. The City of Carmel, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The City of Carmel has the authority to inspect stormwater facilities and practices in order to ascertain that they properly maintained and functioning.

Stormwater Fee

The stormwater fee for non-residential properties is $4.95 per ERU per month. An ERU is an equivalent residential unit and is specified for the city of Carmel as 4,150 square feet.

Non-Residential Example:

Property containing 8,300 square feet would be divided by 4,150 and then multiplied by $4.95 to get the total monthly amount of $9.90.

Discharge Prohibitions.

(a) Prohibition of illicit discharges.

Excerpt from Carmel Municipal Code

Post Construction Stormwater Quality Management.

(a) The City of Carmel has established a minimum standard that the measurement of the effectiveness of the control of stormwater quality will be based on the management of total suspended solids (TSS). The project site owner must submit to the City of Carmel, a post-construction SWPPP that would show placement of appropriate BMP(s) from a pre-approved list of BMPs specified in the City of Carmel Stormwater Technical Standards Manual and would demonstrate that the expected TSS loadings in runoff associated with one inch of rainfall will be reduced by a minimum of 80% at the outfall(s) exiting the site. The noted BMPs must be designed, constructed, and maintained according to guidelines provided or referenced in the City of Carmel Stormwater Technical Standards Manual. Practices other than those specified in the pre-approved list may be utilized. However, the burden of proof, as to whether the performance (minimum 80% TSS removal) and ease of maintenance of such practices will be according to guidelines provided in the City of Carmel Stormwater Technical Standards Manual, would be placed with the applicant. Details regarding the procedures and criteria for consideration of acceptance of such BMPs are provided in the City of Carmel Stormwater Technical Standards Manual.

(b) The following activities are exempt from the requirements of this section:

(1) Agricultural land-disturbing activities; or

(2) Timber harvesting activities; or

(3) Construction activities associated with a single-family residential dwelling disturbing less than five acres, when the dwelling is not part of a larger common plan of development or sale; or

(4) A single-family residential strip development where the developer offers for sale or lease without land improvements and the project is not part of a larger common plan of development of sale; or

(5) Individual building lots within a larger permitted project.

BMP Maintenance

(a) BMPs shall be maintained in a condition that their effectiveness in treating runoff is not diminished, 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 an approved stormwater management permit, and shall not be subsequently altered, revised, or replaced, except in accordance with the provisions of an approved stormwater management permit (as amended or revised) or as approved by the City of Carmel. The BMP owner is considered in violation of this Article if the BMP is not maintained properly.

(b) Following the issuance of an NOT or the installation of an acceptable BMP, inspection and maintenance of the BMP(s) shall be the long-term responsibility of the HOA or entity as specified in restrictive covenants. The HOA or entity is required to inspect the referenced BMP(s) at least once per year. The inspections shall follow the operation and maintenance procedures included in the City of Carmel Stormwater Technical Standards Manual and/or the stormwater management permit for each specific BMP. The inspection shall cover physical conditions, available water quality storage capacity, and the operational condition of key facility elements. The HOA or entity is required to submit a yearly inspection report form (City of Carmel Stormwater Technical Standards Manual) demonstrating proof of inspection, with the first report to be required one year after the HOA or entity gains ownership of the BMP(s), and subsequent reports due each year within the month of the original transfer of ownership. Noted deficiencies and corrective actions taken should be included in the report.

(c) The City of Carmel has the authority to perform long-term inspection of all public or privately owned BMPs. Such inspections will be in addition to that required to be performed by the HOA or the entity on a regular basis. The HOA or entity is in violation of this Article if an inspection report is not submitted to the City of Carmel within one month of the date due, if the HOA or entity fails to correct noted deficiencies within the allowed time period, or if the City of Carmel identifies a violation that was stated as not existing in the submitted inspection report.
