Land development projects and associated increases in impervious cover alter the hydrologic response of local watersheds and increase stormwater runoff rates and volumes, flooding, stream channel erosion, and sediment transport and deposition. This stormwater runoff contributes to increased quantities of waterborne pollutants. Stormwater runoff, soil erosion and nonpoint source pollution can be controlled and minimized through the regulation of stormwater runoff from development sites.
The purpose of this Part is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in the watersheds within the City of Rochester. Therefore, the City of Rochester establishes this set of water quality and quantity policies to provide reasonable guidance for the regulation of stormwater runoff and to, in addition to the above, safeguard persons, protect property, prevent damage to the environment in the City of Rochester, and comply with the NYSDEC state pollutant discharge elimination system (SPDES) general permit for stormwater discharges from municipal separate storm sewer systems (MS4s), for the purpose of protecting local water resources from degradation. It is determined that the regulation of stormwaterrunoff discharges from land development projects and other construction activities in order to control and minimize increases in stormwater runoff rates and volumes, soil erosion, stream channel erosion, and nonpoint source pollution associated with stormwater runoff is in the public interest and will prevent threats to public health and safety.

This Part shall be applicable to land disturbance activities, as defined in § 39-441, and those activities meeting Condition (1), (2), (3) or (4) below shall include water quantity and water quality controls (post-construction stormwater runoff controls) as set forth in § 39-447 as applicable unless eligible for an exemption or granted a waiver by the City of Rochester in accordance with § 39-445:
Stormwater runoff from land disturbance activities discharging a pollutant of concern to either an impaired water identified on the Department's 303(d) list of impaired waters or a total maximum daily load (TMDL) designated watershed for which pollutants in stormwater have been identified as a source of the impairment.
Stormwater runoff from land disturbance activities disturbing five or more acres.
Stormwater runoff from land disturbance activity disturbing between one acre and five acres of land during the course of the project, exclusive of the construction of single-family residences and construction activities at agricultural properties.
Stormwater runoff from land disturbance activity that is smaller than one acre disturbance if such activities are part of a larger common plan of development, even though multiple separate and distinct land disturbance activities may take place at different times on different schedules.
All plans, documents and information required by this Part must be reviewed by the Stormwater Management Officer to ensure that established water quality standards will be maintained during and after development of the site and that post-construction runoff levels are consistent with any local and regional watershed plans.
When a site development plan is submitted that qualifies as a redevelopment project, as defined in § 39-441, decisions on permitting and on-site stormwater requirements shall be governed by special stormwater sizing criteria found in the current New York State Stormwater Management Design Manual. Final authorization of all redevelopment projects will be determined after a review by the City of Rochester. This applies to all redevelopment projects that are greater than or equal to one acre (43,560 square feet).
The following activities may be exempt from the requirements of this Part:
Any emergency activity which is immediately necessary for the protection of life, property or natural resources.
Agricultural activity as defined in this Part.
Silvicultural activity, except that landing areas and log haul roads are subject to this article.
Routine maintenance activities that disturb less than five acres and are performed to maintain the original line and grade, hydraulic capacity or original purpose of a facility.
Repairs to any stormwater treatment practice deemed necessary by the City of Rochester.
This Part is not intended to interfere with, abrogate, or annul any other article, rule or regulation, statute, or other provision of law. The requirements of this Part should be considered minimum requirements, and where any provision of this Part imposes restrictions different from those imposed by any other article, rule or regulation, or other provision of law, whichever provisions are more restrictive or impose higher protective standards for human health and/or the environment shall be considered to take precedence.
Construction activities that involve land disturbance may also require additional compliance measures detailed in other regulations and/or articles.
No person shall receive any of the building, grading or other land disturbance approvals or permits required for land disturbance activities without first meeting the requirements of this Part to the satisfaction of the City of Rochester.
Unless specifically excluded by this Part, any landowner or operator desiring approval or a permit for a land disturbance activity shall comply with all applicable provisions of this Part and shall submit all required plans, documentation and information as required under this Part to the City of Rochester for review and approval.
Unless otherwise excepted by this Part, the following items shall be submitted prior to the issuance of a permit or site plan approval:
Any applicable fees.
All documents required by this Part must be reviewed by the Stormwater Management Officer to ensure that established water quality standards will be maintained after development of the site and that post-construction runoff levels are consistent with any local and regional watershed plans. Information shall be submitted as a single, logical package, with all information bound together.
All persons shall comply with the requirements of this Part, unless a written request is filed to waive the requirements in part or whole for land disturbance activities that disturb less than one acre of land. Requests to waive any requirements of this Part shall be submitted to the City of Rochester for approval.
The minimum requirements for stormwater management may be waived in whole or in part upon written request of the applicant, provided that at least one of the following conditions applies:
It can be demonstrated that the proposed development is not likely to impair attainment of the objectives of this Part.
Alternative minimum requirements for on-site management of stormwater discharges have been established in a stormwater pollution prevention plan that has been approved by the City of Rochester, and the implementation of the plan is required. These practices are encouraged in order to minimize the reliance on structural practices. Credit in the form of reductions in the amount of stormwater that must be managed can be earned through the use of nonstructural practices that reduce the generation of stormwater from the site. These nonstructural practices are explained in detail in the manual Better Site Design: A Handbook for Changing Development Rules in Your Community. Applicants wishing to obtain credit for use of nonstructural practices must ensure that these practices are documented and remain unaltered by subsequent property owners.
Provisions are made to manage stormwater by an off-site facility. The off-site facility is required to be in place, to be designed and adequately sized to provide a level of stormwater control that is equal to or greater than that which would be afforded by on-site practices and there is a legally obligated entity responsible for long-term operation and maintenance of the stormwater practice.
The City of Rochester finds that meeting the minimum on-site management requirements is not feasible due to the natural or existing physical characteristics of a site.
In instances where one of the conditions above applies, the City of Rochester may grant a waiver from strict compliance with these stormwater management provisions, as long as acceptable mitigation measures are provided. However, to be eligible for a variance, the applicant must demonstrate to the satisfaction of the City of Rochester that the variance will not result in the following impacts to downstream waterways:
Furthermore, where compliance with minimum requirements for stormwater management is waived, the applicant will satisfy the minimum requirements by meeting one of the mitigation measures selected by the City of Rochester. Mitigation measures may include, but are not limited to, the following:
The purchase and donation of privately owned lands, or the grant of an easement to be dedicated for preservation and/or reforestation (dedication or easement of land, see § 39-446B). These lands should be located adjacent to the stream corridor in order to provide permanent buffer areas to protect water quality and aquatic habitat.
The creation of a stormwater management facility or other drainage improvements on previously developed properties, public or private, that currently lack stormwater management facilities designed and constructed in accordance with the purposes and standards of this Part.
No waivers or mitigation plans will be considered for land disturbance activity that disturbs one acre or greater of land.
Where the City of Rochester waives all or part of the minimum stormwater management requirements, or where the waiver is based on the provision of adequate stormwater facilities provided downstream of the proposed development, the applicant shall be required to pay a fee in an amount as determined by the City of Rochester. All monetary contributions shall be made to a dedicated fund for stormwater management activities. The fee structure shall be based on the cubic feet of storage required for stormwater management of the development in question. All of the monetary contributions shall be made by the applicant prior to the issuance of any permit or approval for the development.
In lieu of a monetary contribution, an applicant may obtain a waiver of the required stormwater management by entering into an agreement with the City of Rochester for the granting of an easement or the dedication of land by the applicant, to be used for the construction of an off-site stormwater management facility. The agreement shall be entered into by the applicant and the City of Rochester prior to the recording of plats or, if no record plat is required, prior to the issuance of the permit.
The applicant shall consult the New York State Stormwater Management Design Manual and the New York Standards and Specifications for Erosion and Sediment Control for standards and specifications related to stormwater management design criteria. Stormwater management practices that are designed and constructed in accordance with these technical documents shall be presumed to meet the standards imposed by this law. If there is a conflict between any of the standards, the more stringent standard shall apply. Where stormwater management practices are not in accordance with technical standards, the applicant or developer must demonstrate equivalence to the technical standards set forth in this section and § 39-448, and the SWPPP shall be prepared by a licensed professional.
The following design and performance criteria shall be addressed for stormwater management at all sites:
All site designs shall establish stormwater management practices to control the peak flow rates of stormwater discharge associated with specified design storms and reduce the generation of stormwater. These practices should seek to utilize pervious areas for stormwater treatment and to infiltrate stormwater runoff from driveways, sidewalks, rooftops, parking lots, and landscaped areas to the maximum extent practicable to provide treatment for both water quality and quantity.
All stormwater runoff generated from new development shall not discharge untreated stormwater directly into a jurisdictional wetland or local water body without adequate treatment. Where such discharges are proposed, the impact of the proposal on wetland functional values shall be assessed using a method acceptable to the City of Rochester. In no case shall the impact on functional values be any greater than that allowed by the Army Corps of Engineers (COE) or the NYSDEC responsible for natural resources.
An attempt shall be made to maintain annual groundwater recharge rates, by promoting infiltration through the use of structural and nonstructural methods. At a minimum, an attempt shall be made for annual recharge from the post-development site to mimic the annual recharge from pre-development site conditions.
In order to protect stream channels from degradation, a specific channel protection criteria shall be provided as prescribed in the New York State Stormwater Management Design Manual.
Stormwater discharges to critical areas with sensitive resources may be subject to additional performance criteria or may need to utilize or restrict certain stormwater management practices.
Stormwater discharges from land uses or activities with higher potential pollutant loadings, known as "hotspots," may require the use of specific structural stormwater treatment practices and pollution prevention practices.
Prior to design, applicants are required to consult with the City of Rochester to determine if they are subject to additional stormwater design requirements.
The calculations for determining peak flows (WQv), as found in the New York State Stormwater Management Design Manual, shall be used for sizing all stormwater management practices.
A SWPPP is required as part of the compliance with this Part. This plan must be prepared by a qualified professional and must indicate whether stormwater will be managed on site or off site and, if on site, the general location and type of practices and shall also include sufficient information (e.g., maps, hydrologic calculations, etc.) to evaluate the environmental characteristics of the project site, the potential impacts of all proposed development of the site, both present and future, on the water resources, and the effectiveness and acceptability of the measures proposed for managing stormwater generated at the project site. The plan must be signed by a New York State licensed professional engineer (PE), who will verify that the design of all stormwater management practices meets the submittal requirements outlined in the New York State Stormwater Management Design Manual. No building or grading permit or site plan approval shall be issued until a satisfactory stormwater pollution prevention plan, or a waiver thereof, has undergone a review and been approved by the City of Rochester after determining that the plan or waiver is consistent with the requirements of this Part.
The applicant shall employ a responsible individual, as defined in § 39-441, who will oversee the implementation of the SWPPP on a daily basis. The applicant shall also employ the services of a qualified professional in erosion and sediment control who will inspect and document the effectiveness of all erosion and sediment control practices. The documentation will be kept in a site logbook. Inspection reports will be completed every seven days and within 24 hours of any storm event producing 0.5 inch of precipitation or more. A monthly summary of reports will be copied to the site logbook and delivered to City of Rochester within five days after the month's end.
All SWPPPs shall provide the following information:
Description of each post-construction stormwater management practice.
Site map/construction drawing(s) showing the specific location(s) and size(s) of each post-construction stormwater management practice. The map(s) will also clearly show proposed land use with tabulation of the percentage of surface area to be adapted to various uses. A written description of the site plan and justification of proposed changes in natural conditions may also be required.
Hydrologic and hydraulic analysis for all structural components of the stormwater management system for the applicable design storms, including calculations such as a description of the design storm frequency, intensity and duration; time of concentration; soil curve numbers or runoff coefficients; peak runoff rates and total runoff volumes for each watershed area; infiltration rates, where applicable; culvert capacities; flow velocities; data on the increase in rate and volume of runoff for the design storms referenced in the New York State Stormwater Management Design Manual; and documentation of sources for all computation methods and field test results.
Comparison of post-development stormwater runoff conditions with pre-development conditions.
Dimensions, material specifications and installation details for each post-construction stormwater management practice.
The design and planning of all stormwater management facilities shall include detailed maintenance and repair procedures, including a schedule to ensure their continued function. These plans will identify the parts or components of a stormwater management facility that need to be maintained and the equipment and skills or training necessary. 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.
The applicant must ensure access to all stormwater treatment practices at the site for the purpose of inspection and repair by securing all the maintenance easements needed on a permanent basis. These easements will be recorded with the plan and will remain in effect even with transfer of title to the property. See § 39-449 for additional information.
The applicant must execute an easement and an inspection and maintenance agreement binding on all subsequent owners of land served by the on-site stormwater management measure(s) in accordance with the specifications of this Part. See § 39-449 for additional information.
The SWPPP shall be prepared by a qualified professional, and the final plan must be signed by a New York State licensed professional engineer, who shall certify that the design of all stormwater management practices meets the requirements in this Part.
A written or graphic inventory of the natural resources at the site and surrounding area as it exists prior to the commencement of the project and a description of the watershed and its relation to the project site. This description should include a discussion of soil conditions, forest cover, topography, wetlands, and other native vegetative areas on the site. Particular attention should be paid to environmentally sensitive features that provide particular opportunities or constraints for development.
The City of Rochester may also require a concept plan to consider the maximum development potential of a site under existing zoning, regardless of whether the applicant presently intends to develop the site to its maximum potential.
The applicant must present a detailed plan for management of vegetation at the site after construction is finished, 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. This plan must be prepared by a registered landscape architect or by the soil and water conservation district and in compliance with landscaping specifications outlined in the New York State Stormwater Management Design Manual.
The applicant shall assure that all other applicable environmental permits have been acquired for the site prior to approval of the final stormwater design plan.
Maintenance easement. The applicant or owner of the site must execute a maintenance easement agreement that shall be binding on all subsequent owners of land served by the stormwater management facility. The agreement shall provide for access to the facility at reasonable times for periodic inspection by the City of Rochester, or its contractor or agent, to ensure that the facility is maintained in proper working condition to meet design standards and any other provisions established by this Part and to, if necessary, implement emergency repairs to protect the health, safety and welfare of the public. The easement dimensions shall be as directed by the City of Rochester, and the easement agreement shall be recorded in the office of the County Clerk, with a copy provided to the City of Rochester.
Maintenance after construction. The owner or operator of permanent stormwater management practices installed in accordance with this Part shall ensure they are operated and maintained to achieve the goals of this Part. Proper operation and maintenance also includes, as a minimum, the following:
A preventive/corrective maintenance program for all critical facilities and systems of treatment and control (or related appurtenances) which are installed or used by the owner or operator to achieve the goals of this Part.
Written procedures for operation and maintenance and training new maintenance personnel.
Discharges from the stormwater management practices shall not exceed design criteria or cause or contribute to a water quality standard violation.
The maintenance and proper operation of all privately owned stormwater management facilities, including nonstructural practices, shall be ensured through the creation of a formal and enforceable maintenance agreement that must be approved by the City of Rochester and recorded in the office of the County Clerk as a deed restriction on the property prior to final plan approval. This agreement will include any and all maintenance easements required to access and inspect the stormwater management practices and will outline the procedures and schedule to be followed to perform routine maintenance as necessary to ensure proper functioning of the stormwater management practice. In addition, the legally binding agreement shall identify the parties responsible for the proper maintenance of all stormwater treatment practices and include plans for periodic inspections by the owners, or their designated agent, to ensure proper performance of the facility. The maintenance agreement shall be consistent with the terms and conditions of the "Stormwater Control Facility Maintenance Agreement."
The City of Rochester, in lieu of a maintenance agreement, may accept dedication of any existing or future stormwater management facility for maintenance, provided that such facility meets all the requirements of this Part and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance.
Requirements of maintenance agreements. All stormwater management facilities must undergo, at the minimum, an annual inspection to document maintenance and repair needs to ensure compliance with the requirements of this Part and accomplishment of its purposes. These needs may 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. Any maintenance needs found must be identified in writing, along with the schedule and methods to be employed to complete the maintenance. The maintenance repairs and restoration schedule are to be approved by the City of Rochester prior to commencing the work, and the City of Rochester shall inspect the facility upon completion of the work. The inspection and maintenance requirement may be increased by the City of Rochester as deemed necessary to ensure proper functioning of the stormwater management facility.
Records of installation and maintenance activities. Parties responsible for the operation and maintenance of a stormwater management facility shall make records of the installation and of all maintenance and repairs and shall retain the records for at least five years. These records shall be made available to the City of Rochester during inspection of the facility and at other reasonable times upon request.
Maintenance guarantees for privately owned stormwater facilities. Where stormwater management and erosion and sediment control facilities are to be operated and maintained by the applicant or by a corporation that owns or manages a commercial or industrial facility, the applicant, prior to construction, may be required to provide the City of Rochester with an irrevocable letter of credit from an approved financial institution or surety to ensure proper operation and maintenance of all stormwater management and erosion control facilities both during and after construction and until the City of Rochester acknowledges compliance with all details of approved site plan. If the applicant or landowner fails to properly operate and maintain stormwater management and erosion and sediment control facilities, the City of Rochester may draw upon the account to cover the costs of proper operation and maintenance, including engineering and inspection costs, until the City of Rochester acknowledges compliance with all details of approved site plan.
The City of Rochester or designated agent shall make inspections at any reasonable time for purposes of inspecting the construction of the stormwater management facilities. Inspections may include but are not limited to routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; inspection of drainage basins or areas identified as higher-than-typical sources of sediment or other contaminants or pollutants; inspections of businesses or industries of a type which are more likely than the typical discharge to cause violations of state or federal water or sediment quality standards or the SPDES stormwater permit; and joint inspections with other agencies inspecting under environmental or safety laws. Inspections may include but are not limited to reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater management practices. The applicant must notify the City of Rochester in advance before the commencement of construction. If any violations are found, the property owner shall be notified of the nature of the violation and the required corrective actions. No added work shall proceed until any violations are corrected and all work previously completed has received approval by the City of Rochester.
Furthermore, when any new drainage control facility is installed on private property, or when any new connection is made between private property and a public drainage control system, or combined sewer, the property owner shall grant to the City of Rochester the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection. This includes the right to enter a property when it has a reasonable basis to believe that a violation of this Part is occurring or has occurred and to enter when necessary for abatement of a public nuisance or correction of a violation of this Part.
All applicants are required to submit actual as-built plans for any stormwater management practices located on site after final construction is completed. The plan must show the final design specifications for all stormwater management facilities and must be certified by a New York State licensed professional engineer. A final inspection by the City of Rochester is required before the release of any performance securities can occur.
All applicants are responsible for maintaining the grading of the site so that it is consistent with the certified as-built plans. Any post-construction alterations to the landscape shall receive prior approval from the City of Rochester. Temporary landscape alterations, such as those associated with utility excavations and landscaping activities, must be restored to conditions that are consistent with the certified as-built plans.
No person shall commence or conduct any development activity that is contrary to this Part or alter or fail to maintain stormwater pollution prevention measures required by this Part. Violations of this Part II of Article IV of Chapter 39 shall be considered high violations for purposes of the penalties set forth in § 13A-11D of the Municipal Code.
The City of Rochester may, at its discretion, require the submittal of a performance security or bond prior to approval in order to insure that the stormwater practices are installed as required by the approved stormwater pollution prevention plan. The amount of the installation performance security shall be the total estimated construction cost of the stormwater management practices approved by the City of Rochester, plus 25%. The performance security shall contain forfeiture provisions for failure to complete work specified in the stormwater pollution prevention plan. The installation performance security shall be released in full only upon submission of as-built plans and written certification by a New York State licensed professional engineer that the stormwater practice has been installed in accordance with the approved plan and other applicable provisions of this Part. The City of Rochester will make a final inspection of the stormwater practice to ensure that it is in compliance with the approved plan and the provisions of this Part. Provisions for a partial pro rata release of the performance security based on the completion of various development stages can be done at the discretion of the City of Rochester.
