City of Canton


The proper management of the quantity and quality of storm water runoff is crucial to protecting the Canton community. When left unmanaged, the increased quantity of storm water runoff resulting from development and urbanization can lead to flooding and property damage. The unmanaged quality of storm water runoff resulting from development, pollutants, and other illicit discharges degrades the chemical, physical, and biological integrity of Canton's lakes, streams, and other water bodies. Therefore, to alleviate these problems, the City of Canton has taken steps to promote proper storm water management.

In 2009, "Chapter 961: Storm Water Management" was adopted as part of the codified ordinances of the City of Canton to satisfy regulatory requirements of the National Pollutant Discharge Elimination System Storm Water Program. In addition, the "City of Canton Storm Water Management Manual" was adopted to supplement the ordinance by providing further standards, applicability, design criteria, requirements, recommendations, and guidance for various aspects of storm water management in the City of Canton that are not provided explicitly in the ordinance.

The "City of Canton Storm Water Management Manual" should be used any time there are questions regarding City requirements for storm water management related to development or within City right-of-way. In general, whenever there is proposed development in the City of Canton that requires the submission of a site plan to the City Zoning Inspector, the City Engineering Department will need to review and approve the plan for proper storm water quantity management. If the proposed development will disturb one or more acres of land, the Stark SWCD will also need to review and approve the plan for proper storm water quality management. The "City of Canton Storm Water Management Manual" describes all aspects of both storm water quantity and storm water quality management requirements as well as general storm water drainage provisions.

STATE OF OHIO Storm Water Program

CHAPTER 3745-39 OF THE ADMINISTRATIVE CODE

3745-39-02 Objectives of the Ohio EPA storm water management program for small MS4s.

(A) Storm water runoff continues to harm Ohio's waters. Runoff from lands modified by human activities can harm surface water resources in several ways, including the changing of natural hydrologic patterns and elevating pollutant concentrations and loadings. Storm water runoff may contain or mobilize high levels of contaminants, such as sediment, suspended solids, nutrients, heavy metals, pathogens, toxins, oxygen-demanding substances and floatables.

(B) The purpose of the Ohio EPA storm water management program for small municipal separate storm sewer systems (MS4s) is to regulate sources to protect water quality and to establish a comprehensive storm water management program. In this program, small MS4s have flexibility to determine the best management practices and measurable goals that are most appropriate for their system, for each of the six minimum control measures described in paragraph (C) of rule 3745-39-03 of the Administrative Code.

(C) What constitutes a municipal separate storm sewer system is often misinterpreted and misunderstood. The term does not solely refer to municipally owned storm sewer systems, but rather is a term of art with a much broader application that can include, in addition to local jurisdictions, state and federal facilities, public universities, local sewer districts, public hospitals, federal installations, military bases and prisons. The municipal separate storm sewer system is not just a system of underground pipes – it can include roads with drainage systems, gutters and ditches.

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-39-01 of the Administrative Code.]

(2) Minimum control measures.

(e) Post-construction storm water management in new development and redevelopment.

  1. You must develop, implement and enforce a program to address storm water runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that discharge into your small MS4. Your program must ensure that controls are in place that would prevent or minimize water quality impacts.
  2. You must:
  1. Develop and implement strategies that include a combination of structural, non-structural, or both types of best management practices as you determine appropriate for your community;
  2. Use an ordinance or other regulatory mechanism to address post-construction runoff from new development and redevelopment projects to the extent allowable under state or local law; and
  3.  Ensure adequate long-term operation and maintenance of best management practices.

EXHIBIT A TO CH. 961

CITY OF CANTON STORMWATER MANAGEMENT MANUAL

(February 2012)

4. STORM WATER QUALITY MANAGEMENT

Storm Water Quality Management is the implementation of storm water management systems on a site for proper management of the quality of construction site and post-construction storm water runoff. Storm water quality management attempts to reduce or eliminate erosion and sedimentation caused by storm water runoff as well as the transportation of pollutants in storm water runoff to water resources.

Chapter 4 of this manual provides minimum standards, requirements, and recommendations for storm water quality management. A person's compliance with the same shall not relieve such person from the duty of enacting all measures necessary to minimize pollution of receiving waters.

4.1 Applicability

All development, redevelopment, soil-disturbing activities, or other activities that disturb greater than or equal to one acre of land, including projects less than one acre that are part of a larger common plan of development that is greater than or equal to one acre, regardless of whether or not a site plan is required to be submitted per the Planning and Zoning Code of the City of Canton, shall be subject to all applicable requirements and specifications of Chapter 4 of this manual.

Although not subject to the specific requirements of Chapter 4 of the manual, soil-disturbing activities that disturb less than 1 acre of land or result in exposed soil of less than 1 acre should ensure appropriate practices are in place (such as perimeter silt fence, storm drain inlet protection, etc.) prior to and during the activity to minimize erosion, sedimentation, and storm water pollution. Construction plans should include all such practices even if an NPDES Permit for Storm Water Discharges Associated with Construction Activity is not required.

Chapter 4 and all subsections of Chapter 4 are not intended to provide an exhaustive list and descriptions of all requirements necessary to prepare plans, specifications, reports, calculations, and other information needed for applicable storm water quality management. The designer shall follow generally accepted standards for engineers, architects, and surveyors, as applicable. All requirements of Chapter 4 shall be designed and prepared in conformity with other sections of this manual, as applicable.

The City of Canton’s requirements for storm water quality management are based on the Stark County Storm Water Quality Regulations, as written by the Stark SWCD.

By ordinance, Stark SWCD is a designated representative of the City of Canton Director of Public Service for the administration of this Chapter and associated reviews and site inspections. As such, Stark SWCD has the authority to issue Notices Of Violation and Stop Work Orders for non-compliant activities.

Latest section revisions: 2/16/12

4.3 General Requirements, Standards, and Criteria

All activities meeting the applicability [see Section 4.1] for storm water quality management requirements shall satisfy all applicable requirements and specifications of Chapter 4 of this manual as well as the following:

  1. The property owner or authorized designee of sites with applicable activities shall obtain and comply with the current Ohio EPA NPDES Permit (No. OHC000003) for Storm Water Discharges Associated with Construction Activity. Note: The property owner or designee is responsible for filing a Notice Of Intent (NOI) and Notice Of Termination (NOT) to Ohio EPA accordingly;
  2. All applicable activities and practices shall comply with the current edition of Ohio Department of Natural Resources’ Rainwater and Land Development Manual, as appropriate;
  3. All applicable activities and practices shall comply with other applicable requirements as described or referred to within Chapter 961 of the City of Canton Codified Ordinances or this manual;
  4. No work shall commence without an approved SWP3 [see Section 4.6] and a pre-construction meeting has been held with the Stark SWCD [see Section 4.7].

Latest section revisions: 12/20/11

4.4 Performance Standards

Any person who undertakes any applicable land-disturbance activity shall ensure that soil erosion, sedimentation, increased pollutant loads, and changed water flow characteristics resulting from the activity are controlled so as to minimize pollution of receiving waters. All properties, buildings, infrastructure, roadways, and water resources adjacent to and downstream of the applicable activity shall be protected to the maximum extent practicable from erosion, sedimentation, and other storm water pollution caused by or resulting from the respective site in which storm water quality management is required.

4.5 Acceptable Storm Water Best Management Practices (BMPs)

  1. BMPs used to satisfy storm water quality management requirements shall conform, at a minimum, to the current Ohio EPA NPDES Permit for Storm Water Discharges Associated with Construction Activity, the current edition of Ohio Department of Natural Resources’ Rainwater and Land Development Manual, and the current requirements of Chapter 6111 of the Ohio Revised Code;
  2. Any new or innovative BMP not found in the current edition of Ohio Department of Natural Resources’ Rainwater and Land Development Manual and proposed to be used to satisfy any storm water quality management requirements must be reviewed and approved by Stark SWCD before incorporating them into an SWP3 or implementing on a regulated site;
  3. “Green concepts”, low impact development concepts, “smart growth”, and other alternative planning, design, or development concepts that promote alternative approaches to storm water quality management and the preservation of natural resources may be encouraged or allowed upon the review and approval of the City Engineer and in accordance with applicable Planning and Zoning regulations.
  4. Small construction projects (between 1 and 5 acres of land disturbance) should incorporate a mixture of structural and non-structural post-construction BMPs. Examples include, but are not limited to: conservation easements, riparian setbacks, vegetative filter strips, preservation of green spaces, grassy swales, infiltration trenches, sand filters, bioretention cells, rain barrels, permeable pavement, roof gardens, catch basin inserts, hydrodynamic separators, media filters, etc. See Ohio EPA’s Post Construction Q&A Document for further guidance.

4.10 Post-Construction Storm Water Quality Management

  1. Applicability: Post-construction storm water quality management BMPs shall be provided, as applicable, per the current Ohio EPA NPDES permit for Storm Water Discharges Associated with Construction Activity. All post-construction storm water runoff quality management BMP designs shall be submitted to and approved by Stark SWCD before construction. All associated design calculations and necessary plans and details shall be provided with the Storm Water Management Report and Construction Plans submittal, respectively.
  2. Exemptions: Activities otherwise regulated by Chapter 4 of this manual shall be exempt from meeting post-construction storm water quality management requirements if:
    1. It can be demonstrated that post-construction storm water quality management has been satisfactorily provided for the respective activity:
    2. As part of a larger common plan of development;
    3. By a local or regional post-construction storm water quality BMP.
    4. Proof can be provided that a waiver has been obtained from or exemption has been granted by Ohio EPA.
  3. Public road and highway project requirements: Public road and highway projects that fall under storm water quality management requirements may follow the post-construction storm water requirements and specifications provided in the current edition of ODOT’s L&D Manual – Volume II – Drainage Design, unless otherwise required by Ohio EPA.
  4. Additional standards and requirements:
    1. When a post-construction storm water quality management BMP is to be used to also satisfy applicable storm water detention requirements, the entire storm water detention volume should be “stacked” on top of the storm water quality volume. This means that the lowest invert elevation of any orifice, weir, pipe, or other outlet used to discharge the storm water detention volume into the outlet structure must be set at or above the water quality elevation. There are three reasons that justify this requirement:
      1. It generally keeps the storm water detention design and review separate from the post-construction storm water quality design and review;
      2. It allows the BMP to continue to fully function as a detention facility in case the water quality orifice becomes clogged, resulting in a pool of water that fills the BMP to the lowest detention outlet elevation. Thus, until the clog is removed, the storage capacity reserved for the water quality volume is lost, resulting in only the capacity for the detention volume and the function of a storm water detention facility only;
      3. It results in an additional factor of safety to the BMP/facility by providing additional storage capacity.
  5. The combined storm water quality and storm water quantity discharge rates at the point of analysis shall not exceed allowable/pre-developed discharge rates for each respective storm event;
  6. Post-construction storm water quality orifices shall not be less than 2½” in diameter, unless it can be demonstrated that specific measures will be implemented to prevent clogging. It is recommended that alternative BMPs be used rather than BMPs having orifices smaller than 2½” in diameter;
  7. Unless it can be demonstrated that upstream on-site or off-site areas or connections will not be adversely affected, the outlet invert elevations of any storm sewers or pipes discharging into the BMP must be set at or above the water quality volume elevation. This prevents the slow-draining water quality volume from backing up into the storm sewer which may result in flooding or other nuisance to upstream areas and/or connections;
  8. Any alternative structural storm water quality BMPs must be approved by the Stark SWCD and the City Engineer.
  9. Additional guidance: Ohio EPA has prepared a Post-Construction Question and Answer Document for guidance regarding post-construction storm water management requirements applicable to the current version of Ohio EPA’s NPDES Permit for Storm Water Discharges Associated with Construction Activity. This document is available on Ohio EPA’s website in the Storm Water Program link.

4.12 Maintenance of Post-Construction Storm Water Quality BMPs

All permanent storm water quality BMPs approved pursuant to the requirements of Chapter 4 of this manual should be properly maintained in order to satisfy the purposes of Chapter 961 of the City of Canton Codified Ordinances. Depending on the drainage characteristics of the site and vicinity, there may be documentation necessary to assist in the proper maintenance of storm water management systems on a site, such as Long-Term Maintenance Plans and/or Drainage Easements.

1. Long-Term Maintenance Plan (LTMP)

A. A LTMP shall be prepared by the subject property owner or authorized designee any time Post-Construction Storm Water Quality BMPs are required because:

  1. The site’s owner and/or other responsible parties need to be aware of and how to meet long-term maintenance expectations and responsibilities to ensure the proper operation and function of the post-construction storm water quality BMPs on the site. A LTMP assures the City that the owner and/or responsible party is aware of such expectations and responsibilities;
  2. Ohio EPA’s NPDES Small MS4 Permit requires the City of Canton to “…ensure adequate long term operation and maintenance of [permanent post-construction storm water quality management] BMPs [that discharge to the City’s municipal separate storm sewer system (MS4)].” The City believes that LTMPs assist in satisfying this permit requirement;
  3. Ohio EPA’s NPDES Permit for Storm Water Discharges Associated with Construction Activity requires a “post-construction operation and maintenance plan” (A.K.A. “Long-Term Maintenance Plan”) to be provided as a stand alone document.

B. A separate LTMP shall be submitted for BMPs located on separate properties. One LTMP may be submitted for multiple BMPs located on the same property as long as all minimum content requirements are met;

C. The LTMP should be submitted for review with the SWP3;

D. LTMPs shall be “stand-alone” documents. That is, they should include everything necessary to provide the required maintenance of BMPs without having to reference separate documentation such as construction plans, public records, etc. Copies of any “separate” documentation should be included with the LTMP.

E. At a minimum, the content of LTMPs must include the following, or as otherwise required by Stark SWCD and/or the City Engineer:

  1. A description of the subject property/site location (address, lot number, subdivision name, etc.) in which each of the respective BMPs are located;
  2. The name of the party (person(s), association, or other entity) designated responsibility for the long-term operation and maintenance of the BMPs/systems, and appropriate contact information (name(s), title(s), address(es), telephone number(s), etc.);
  3. A description of the location, type, and function of each of the respective BMPs used on the subject property, including contributing drainage area and any off-site properties in which runoff will benefit from the respective BMPs;
  4. A description of the storm water management system(s) that are proposed to directly receive discharges from the respective BMPs. For example, “The receiving storm water management system for the extended detention basin = Middle Branch of the Nimishillen Creek” or “The receiving storm water management system for 18” private storm sewer = City of Canton public storm sewer (MS4)”, etc;
  5. Any critical design and/or construction information (including as-built information, as applicable) necessary for the proper maintenance and performance of each of the respective BMPs;
  6. A description of how each of the BMPs will be inspected, including a list of inspection tasks and frequency/schedule of inspections;
  7. A description of how each of the BMPs will be maintained to perform their intended function, including a list of routine and non-routine maintenance tasks;
  8. A description of how each of the BMPs will be operated and maintained in the absence or dissolution of the designated responsible party, including how such responsibilities will be transferred upon the sale of the subject property;
  9. A description of how the long-term operation and maintenance of each of the BMPs will be ensured by the responsible party. Include a description of any deed restrictions, easements, agreements, or environmental covenants required;
  10. A statement that any pollutants collected by respective BMPs are to be disposed of in accordance with local, State, and Federal guidelines;
  11. An acknowledgement of the City’s inspection and enforcement rights under Chapter 961 of the City of Canton Codified Ordinances;
  12. A prohibition of alterations of BMPs unless otherwise approved by the City Engineer;
  13. A map showing the site(s), BMPs, access easements, etc.
  14. A copy of the approved Storm Water Pollution Prevention Plan for the subject property;
  15. A copy of any respective easement plat(s) associated with storm water management for the site;
  16. Any Ohio EPA provisions or requirements for LTMPs (A.K.A. “Post-Construction Operations and Maintenance Plans” as per Ohio EPA’s Permit for Storm Water Discharges Associated with Construction Activity under the National Pollutant Discharge Elimination System) that are not otherwise already addressed;
  17. A signature and acknowledgement statement by the subject property owner of his/her understanding and acceptance of the contents and requirements of the LTMP. Signatures of the City Engineer and/or the Stark SWCD may also be required.

F. A copy of the approved LTMP shall be provided by the subject property owner or authorized designee to all designated responsible parties.

2. Drainage Easements

The applicability, standards, and requirements for Drainage Easements necessary for post-construction storm water runoff quality management shall be the same as that described in Section 3.15 of this manual, at a minimum, or as otherwise required by Stark SWCD and/or the City Engineer.

Latest section revisions: 12/21/11

4.13 Long-Term Inspection and Maintenance

Owners/responsible parties are required to inspect post-construction BMPs and keep them maintained and in working condition in accordance with terms described in Long-Term Maintenance Plans. The Stark SWCD performs annual inspections of permanent post-construction storm water quality BMPs for maintenance status on sites that are no longer under construction. Notification of the inspections and any required actions are sent to the responsible party and the City of Canton. Inspections by the Stark SWCD do not relieve the responsible party from their obligation to inspect and maintain respective post-construction storm water quality BMPs.

In addition, if a private post-construction BMP is determined to be the source of an illicit discharge into the City’s MS4 (storm drainage system), appropriate actions may be taken by the City to rectify the illicit discharge in accordance with the enforcement provisions of Chapter 961 of the City of Canton Codified Ordinances.
