I. Introduction
On January 7, 2010, the Northeast Ohio Regional Sewer District’s (District) Board of Trustees
approved Resolution No. 1‐10, Authorization to Implement a District Regional Stormwater
Management Program through the adoption of Title V of the Code of Regulations. Title V
provides for a stormwater fee and credits for account holders who effectively manage
stormwater to reduce impacts on the regional stormwater system.
The District’s Regional Stormwater Management Program addresses flooding, erosion and
water quality problems throughout the District’s service area. Stormwater‐related problems
must be addressed regionally because what happens in one community affects another and
these problems cannot be effectively solved without taking a watershed‐based approach.
Managing stormwater flows is critical for several reasons:
Excessive stormwater overwhelms storm drainage systems including
streams, culverts and storm drain pipes and causes local and regional
flooding.
Stormwater erodes the land, damaging roads, bridges and other
infrastructure, increasing the amount of pollutants added to local
streams and Lake Erie.
The District’s stormwater management program establishes the regional stormwater
system. The regional stormwater system includes the system of watercourses, stormwater
conveyance structures, and stormwater control measures in the District’s service area that
receive drainage from three hundred (300) acres of land or more. Under the District’s
stormwater management program the regional stormwater system is a public system,
similar to water or sanitary systems, which provides a public benefit and is maintained by
the region. When a forested or grassy area is paved and impervious surface is added, a
larger amount of surface water enters the regional stormwater system. Impervious surface
is therefore charged a fee based on the amount of hard surface on a property.
NEORSD Stormwater Fee Credit Policy Manual January 2017
2
A. What is a Stormwater Fee?
The stormwater fee charged to an account holder is based on the impervious surface
on the account holder’s property. The District measures the amount of impervious
surface based on the number of Equivalent Residential Units (ERUs) per property. One
(1) ERU is equal to 3,000 square feet of impervious surface and has an associated fee
per month that is established by the District. Under Title V, stormwater fees are
categorized as either residential or non‐residential.
Residential property is placed into one of three tiers based on the square footage of
the property’s impervious surface:
Tier 1: Small Residential (less than 2,000 sq. ft. impervious)
Tier 2: Medium Residential (2,000 to 3,999 sq. ft. impervious)
Tier 3: Large Residential (4,000 sq. ft. or more impervious)
The non‐residential fee is based on the calculated number of ERUs for the existing
impervious surface multiplied by the base ERU fee.
The stormwater fee for properties within the District service area can be found at
http://www.neorsd.org/stormwaterfeemap.php
B. What is a Stormwater Fee Credit?
Account holders can receive a reduction in their stormwater fee through stormwater
fee credits. The stormwater fee credit is a conditional reduction in the stormwater fee
if an account holder takes measures to reduce the stormwater rate or volume and/or
protect the water quality of runoff flowing from his or her property to the regional
stormwater system. The credit can be obtained through:
Installation and continuing use, operation, and maintenance of an
approved stormwater control measure (SCM) that the District does not
own, maintain, or operate; or
Activities that reduce or alleviate the District’s cost of providing a
regional stormwater management program.
NEORSD Stormwater Fee Credit Policy Manual January 2017
3
A SCM is an activity, measure, structural device, or facility that prevents or reduces
the transport of pollutants, controls stormwater volume and/or rate, and/or limits
impacts to the regional stormwater system. These measures can include on‐site
practices such as rain gardens, bioretention cells, stormwater basins, and other
practices that manage stormwater at its source. Only those impervious surfaces
associated with a SCM are eligible for credit based on that SCM.
C. What Credits Are Available and Who Qualifies?
Table 1 outlines the type of credits available to each type of account holder. The
ability of an account holder to receive any of the credits is dependent on the account
holder owning and maintaining a District‐approved SCM and providing the
documentation required. Credits are available to all qualifying SCMs, whether
constructed before or after initiation of the District’s Regional Stormwater
Management Program.
1. Individual Residential Property Credit: Flat Reduction of 25%
An Individual Residential Property Credit of 25% is available to applicants who own
a property that contains a single‐family home or a multifamily housing complex of
four (4) units or less. The applicant must show that a District‐approved SCM has
been effectively implemented on the property. District‐approved SCMs include:
Rain Gardens
On‐Site Stormwater Storage
Impervious Surface Reduction
Pervious Pavement
Vegetated Filter Strips
See Section II for specific qualifications and details for this credit.

* An individual residential property can receive either the Individual Residential Property Credit or
Stormwater Quality Credit, but not both.
** A Homeowners or Condominium Association can apply on behalf of its members.
2. Stormwater Quantity Credit: Reduction up to 75%
A Stormwater Quantity Credit is available to applicants who have District‐approved
SCMs that reduce the rate and/or volume of stormwater runoff flowing from
impervious surfaces on the applicant’s property. Only the impervious surfaces of a
particular site that drain through the SCM are eligible for a credit. This credit is
separated into two (2) categories:
Peak Flow Credit: Up to 25% credit
Runoff Volume Credit: up to 50% credit
See Section III for specific qualifications and details for this credit.
3. Stormwater Quality Credit: Reduction up to 25%
A Stormwater Quality Credit of up to 25% is available to applicants who have
District‐approved SCMs that provide water quality treatment to stormwater runoff
flowing through the SCM. The credit is only available for the impervious surfaces
that drain to each SCM. The District has established a list of eligible SCMs that can
be used to treat stormwater from associated impervious surfaces and receive a
Stormwater Quality Credit. There are also a Quality Credits available specifically for
NEORSD Stormwater Fee Credit Policy Manual January 2017

those industrial properties that have a stormwater related NPDES Permit and
agricultural properties that have natural resource management plans.
See Sections IV, V, and VI for specific qualifications and details for this credit.
4. Education Credit: Flat Reduction of 25%
The Education Credit is available to all public and private primary, elementary, and
secondary school account holders that are recognized in the State of Ohio and that
provide District‐approved stormwater pollution prevention curricula to at least
25% of the grade levels across the school or school district. The Education Credit is
25% of the stormwater fee for all the properties at which education curricula are
delivered. An Education Credit can be combined with the Stormwater Quality
and/or Quantity Credit for a maximum of 100% credit for a particular school
property.
See Section VIII for specific qualifications and details for this credit.
NEORSD Stormwater Fee Credit Policy Manual January 2017

II. Individual Residential Property Credit
Individual residential account holders who implement stormwater control measures (SCMs)
may be eligible for a reduction of 25% of the stormwater fee for use of one or more of the
following permitted SCMs. See Section II.C for restrictions
A. SCMs
1. Rain Garden
Rain gardens are landscaped areas that are designed to capture and filter
stormwater runoff from a roof or other impervious surface. The plants and soil of
the rain garden provide an easy, natural way of reducing the amount of
stormwater runoff from individual residential properties. To obtain the Individual
Residential Property Credit, the rain garden must meet the following criteria:
At least 25% of a property’s roof area or an equivalent impervious surface
area on the property must drain to the rain garden.
The rain garden must be sized and constructed in accordance with the
worksheet in the Rain Garden Manual for Homeowners.
Stormwater overflows from the rain garden must be directed to appropriate
outlets to the storm drainage system and away from neighboring properties,
sidewalks, steep slopes, or retaining walls.
2. On‐Site Stormwater Storage
On‐site stormwater storage may include rain barrels, cisterns, bladders, or other
stormwater storage devices approved by the District. Credit may be approved if
the following criteria are met:
50% of the property’s roof area is properly connected to rain barrels or other
approved storage devices that provide at least 40 gallons of storage per
downspout, or storage devices must be sized to hold the runoff from 50% of
the property’s roof area during a 1‐inch rainfall event. (See On‐Site
Stormwater Storage Fact Sheet in Appendix B for calculation details.)
On‐site stormwater storage must be covered with a lid or screen that
prevents mosquitoes from entering the storage container.
NEORSD Stormwater Fee Credit Policy Manual January 2017
7
On‐site stormwater storage must be completely drained in no less than 24
hours, and no longer than 4 days, after each rainfall event. Longer drainage
periods may be acceptable if the storage device is larger than the minimum
required storage.
Stormwater overflows from on‐site stormwater storage or the draining of on‐
site storage devices must be directed to appropriate outlets to the storm
drainage system or to vegetated areas, and away from neighboring
properties, sidewalks, steep slopes, or retaining walls.
3. Impervious Surface Reduction
An Individual Residential Property Credit can be obtained if an applicant removes
500 square feet or more of existing impervious surface and replaces it with a
vegetated, pervious surface. Account holders may also request a recalculation of
their tier if they remove impervious surface (see Section F below).
4. Pervious Pavement
Pervious pavement may include paving blocks, grid pavers, pervious asphalt, or
pervious concrete. Pervious pavements can be used for driveways and patios with
a open stone reservoir underneath. The reservoir temporarily stores surface runoff
before infiltrating it into the soil below the stone reservoir. Runoff can be
infiltrated directly into the soil reducing runoff. Gravel driveways and traditional
brick pavers or concrete pavers without spacing lugs are not considered a type of
pervious pavement and are not available for any stormwater fee credit (see
Pervious Pavement Fact Sheet in Appendix B for more information).
Credit may be approved if the following criteria are met:
The pervious pavement is installed for the purpose of runoff infiltration or
detention.
Area of pervious pavement is at least 1,000 square feet.
The open stone reservoir underneath the pervious pavement is at least 10
inches deep at all points.
The installation meets the local building and zoning standards for driveway
installations.
NEORSD Stormwater Fee Credit Policy Manual January 2017
8
Account holders may also request a recalculation of their tier if they install
pervious pavement (see Section F below).
5. Vegetated Filter Strips
Vegetated filter strips are uniform strips of dense turf, meadow grasses, trees or
other vegetation with a minimum slope to slow runoff and improve water quality.
In certain circumstances a large lawn may meet the criteria for a vegetated filter
strip. Credit may be approved if the following criteria are met:
50% of the property’s roof area drains to the vegetated filter strip.
Filter strips are fully vegetated and vegetation is healthy.
The vegetated filter strip complies with the standards outlined in the
District’s fact sheet on Residential Vegetated Filter Strips (see Appendix B).
B. Maintenance Requirements
1. SCMs
SCMs installed on a property must be maintained to ensure continued function of
the SCM. Maintenance recommendations for the SCMs can be found in the Rain
Garden Manual for Homeowners, and on the District Fact Sheets for On‐Site
Stormwater Storage, Pervious Pavement, and Vegetated Filter Strips found in
Appendix B.
2. Responsibility
The applicant, or one of the co‐applicants, has legal responsibility to maintain the
SCM. The recertification process will require documentation that the SCM is
continuing to function as originally intended.
NEORSD Stormwater Fee Credit Policy Manual January 2017
9
C. Restrictions
1. Eligibility
Individual Residential Property Credits are restricted to applicants that own a
property that contains a single family home or a multi‐family housing complex of
four (4) units or less.
2. Local Community Requirements
A stormwater fee credit is only applicable for SCMs that are allowed by the
member community in which the property is located. SCMs must meet all
applicable building, subdivision and planning, and zoning code requirements of
member communities including downspout disconnection, landscaping and
property setbacks requirements. Applicants must contact their local community to
determine applicability. NEORSD cannot approve a credit for a practice that does
not comply with local community regulations.
3. Transfer of Credit
The Individual Residential Property Credit applies only to the applicant.
Credits do not transfer if ownership changes. A new application must be
submitted for new account holders to continue receiving the Individual
Residential Property Credit.
4. Individual Residential Property Credit Limit
Individual residential SCMs cannot be combined on a property for a credit larger
than 25% (see Sections III and IV for other credit opportunities).
5. Quality Credit Restriction
Applicants will not receive the Individual Residential Property Credit for SCMs that
have been given the Stormwater Quality Credit.
NEORSD Stormwater Fee Credit Policy Manual January 2017
10
D. Specific Application and Documentation Requirements
To receive the Individual Residential Property Credit, the applicant must submit the
documentation listed below. A complete application must be submitted for the
District to begin the review process.
1. General Application (Appendix A).
2. Individual Residential Property Credit Application (Appendix B).
3. Applicants must provide appropriate documentation that the SCM has been
installed according to standards and requirements detailed above, and must
provide a photograph of each SCM.
E. Recertification
1. The Individual Residential Property Credit is valid for three (3) years. The applicant
must submit the District’s recertification application to continue to receive credits
towards their stormwater fee (see Appendix G2).
2. Failure to submit recertification information by the required deadline will result in
elimination of the credit. The District will notify account holders in advance of
credit expiration dates and recertification deadlines.
F. Tier Adjustment
1. If a property owner implements the requirements for the Impervious Surface
Reduction or Pervious Pavement fee credits and successfully applies for a credit, a
recalculation of their total impervious area will occur. If the total impervious area
reduction places the property in a lower tier, the lower tier rate will apply instead
of the fee credit. If a lower tier is achieved through reduction of impervious area
the property owner may still achieve a credit at that lower tier by implementing a
stormwater control measure as outlined under the residential fee credit program.
NEORSD Stormwater Fee Credit Policy Manual January 2017
11
III. Stormwater Quantity Credit
The Stormwater Quantity Credit is available for applicants who implement SCMs designed
to control stormwater peak flows and volumes. This will reduce the burden on stormwater
infrastructure, including streams, storm sewers, combined sewers and other receiving
waters, and can reduce flooding frequency and magnitude. This credit is separated into two
categories: Peak Flow Credit and Runoff Volume Credit. To ensure maximum stormwater
quality and quantity credits for SCMs on new development and redevelopment projects, the
District strongly recommends that interested applicants contact the District early in the
design phase of a project to discuss the planned SCMs and intended stormwater
management plan.
A. Peak Flow Credit SCMs and Design Standards
The District will provide up to a 25% credit for impervious surfaces that drain through
a SCM that controls the peak discharge rates using the established design standards
listed in Table 2.
Table 2. Stormwater Quantity – Peak Flow Credits Available
Credit
Available Design Standard
25% Critical Storm Method
15% Member Community or NEORSD (Title IV: Combined Sewer Code) Detention Standard (other
than Critical Storm)
10% Existing On‐Site Detention SCM, no documentation of meeting Critical Storm Method or
member community detention standards
1. Critical Storm Method
A Stormwater Quantity Credit of 25% may be provided to an applicant for a SCM
that controls the peak discharge rate using the Critical Storm Method or any other
method that exceeds the Critical Storm Method requirements.
NEORSD Stormwater Fee Credit Policy Manual January 2017
12
The Critical Storm Method requires:
The peak rate of runoff from a Critical Storm and all more frequent storms
occurring on the development area will not exceed the peak rate of runoff
from a 1‐year frequency storm over the same area under predevelopment
conditions.
Storms of less frequent occurrence than the Critical Storm, up to the 100‐
year storm, have peak runoff rates no greater than peak runoff rates from
equivalent size storms under predevelopment conditions.
See the following ODNR Reference for more details on the Critical Storm Method.
http://water.ohiodnr.gov/water‐use‐planning/stormwater‐management
To receive the Peak Flow Credit the applicant must submit either:
A stormwater management plan with calculations for existing stormwater
runoff flows and timing into and through all SCMs using the Critical Storm
Method, or
Documentation from the member community that the SCM has been
designed according to the Critical Storm Method. This documentation shall
provide evidence that the Critical Storm Methodology was required by the
community at the time of construction. See Appendix D Member Community
Review form.
Submittals to verify the Critical Storm Method must be completed for both pre‐
and post‐ development land use conditions and include the underlying
assumptions and hydrologic and hydraulic methods and parameters used for these
calculations. The applicant must also include the Critical Storm determination and
demonstrate that the runoff from upstream areas have been considered in the
calculations.
NEORSD Stormwater Fee Credit Policy Manual January 2017
13
The documentation from a member community may include any of the following:
Member community approved engineering plans for the SCM,
Formal approval letter from the member community engineer, or
A completed Member Community Review Form (Appendix D).
It is the responsibility of the applicant to provide this documentation to the
District. The applicant can request that the member community complete the
Member Community Review Form, but the member community may decline
completing the form due to the lack of information that confirms the SCM was
designed and built to the standards described in this section.
For redevelopment sites, the pre‐developed condition for existing impervious
surfaces shall be defined as grassland in good hydrologic condition for the pre‐
developed peak discharge rates, critical storm and volume storage calculations. In
no cases will the District provide a credit for peak flow reduction without the
existence or construction of an appropriate stormwater control measure.
2. Member Community Detention Standard
A credit of 15% may be provided to an applicant for impervious surfaces that have
SCMs that control the peak discharge rate using a method required by a member
community’s regulation if less stringent than the Critical Storm Method, or the
NEORSD Title IV requirements if within the combined sewer system. To receive
credit in the combined sewer area, the applicant must demonstrate that the post‐
construction peak discharge rate for the 6‐month 24‐hour storm up to the 5‐year
24‐hour storm does not exceed the 6‐month 24‐hour pre‐development peak
discharge rate, consistent with District policies under Title IV. To receive the Peak
Flow Credit the applicant must submit either:
A stormwater management plan with the calculations required for the
member community detention standard, or
Documentation from the member community that the SCM has been
designed according to the member community detention standard in place
at the time of construction.
NEORSD Stormwater Fee Credit Policy Manual January 2017
14
In no case will the District provide a credit for peak flow reduction without
the existence or construction of an appropriate stormwater control measure.
In the separate storm sewer areas, redevelopment projects must
demonstrate a 25% reduction in peak runoff for all storms up to a 5‐year 24‐
hour event, all other storms may not exceed the pre‐existing condition.
The documentation from a member community may include any of the following:
Member community approved engineering plans for the SCM,
Formal approval letter from the member community engineer, or
A completed Member Community Review Form (Appendix D).
It is the responsibility of the applicant to provide this documentation to the
District. The applicant can request that the member community complete the
Member Community Review Form, but the member community may decline
completing the form due to the lack of information that confirms the SCM was
designed and built to the standards described in this section.
3. Existing On‐Site Detention SCMs
A Stormwater Quantity Credit of 10% may be provided to an applicant for
associated impervious surfaces that have a SCM that controls the peak discharge
rate using a method that does not meet either the Critical Storm Method or
current member community regulations. This may also be applicable for a SCM
that does not have detention calculations available or was built prior to current
regulatory standards. To receive the Stormwater Quantity Credit for detaining the
peak flow the applicant must submit a site map and plans including details of the
outlet control structure. The principle spillway must provide for detention of storm
events.
NEORSD Stormwater Fee Credit Policy Manual January 2017
15
B. Runoff Volume Credit SCMs and Design Standards
A Stormwater Quantity Credit of up to 50% may be provided to an applicant for
impervious surfaces that drain through a SCM (or a series of SCMs) that maintain or
reduce runoff volume. The intent of the Runoff Volume Credit is to limit the negative
impacts of changing site hydrology by reducing impervious surfaces, increasing
stormwater infiltration, increasing evapo‐transpiration and harvesting or recycling of
rainwater. SCMs may include, but are not limited to infiltration practices, rainwater
harvesting, and bioretention.
To receive this portion of the Stormwater Quantity Credit the applicant must show
that SCMs and the stormwater management plan meet the volume reduction
requirements. The method used to estimate stormwater runoff volumes must be
widely accepted and recognized by the District. Riparian and wetland setbacks must
also be included based upon the criteria in Appendix F.
Table 3 identifies the credit percentage, type, site and property characteristics, and
criteria required to obtain the runoff volume credit. A runoff volume credit of 25% is
offered for applicants managing the stormwater runoff volume for the 2‐year 24‐hour
storm. Depending on the existing site imperviousness listed in Table 3, a SCM must
reduce the volume by 25% or must maintain pre‐developed volume conditions. An
exceptional runoff volume credit of 50% is available for applicants employing SCMs
that manage the runoff volume for the 100‐year 24‐hour storm. Applicants achieving
the 50% exceptional runoff volume credit will not be eligible for the 25% runoff
volume credit.

100‐year 24‐hour design storm.
1a. Runoff Volume Credit ‐ Existing Imperviousness Greater than 50%
A credit of 25% may be provided to applicants with existing impervious surfaces
greater than 50% of the property who:
Implement a stormwater management plan and SCMs that result in a 25%
decrease in the volume of stormwater runoff from the 2‐year 24‐hour design
storm; and
Incorporate riparian and wetland setbacks into the site development that
either follow the member community standards or are a minimum of 25 feet
from all watercourses and Category 2 and 3 wetlands, whichever is more
restrictive. If the applicant’s property does not contain wetlands or
watercourses, this requirement does not apply.
The applicant must show that the post‐development quantity (volume) from a 2‐
year 24‐hour storm event is at least 25% less than the predevelopment existing
site values. Hydrologic and hydraulic calculations are required to estimate the
volumes, using various methods and computer‐based software including the U.S.
NEORSD Stormwater Fee Credit Policy Manual January 2017
17
Natural Resources Conservation Service (NRCS) methods for predicting runoff
volumes. Methods should include the development of pre‐ and post‐ developed
hydrographs to determine the runoff volume generated. Care should be taken not
to overestimate initial abstraction values when using the NRCS methodology. The
implemented SCMs must have the ability to dewater 25% of the 2‐year 24‐hour
event within 3 days (72 hours) to permit capture of consecutive storm events.
1b. Runoff Volume Credit ‐ Existing Imperviousness Less than 50%
A Stormwater Quantity Credit of 25% may be provided to applicants with existing
impervious surfaces of or less than 50% for the property who:
Implement a stormwater management plan that prevents the post‐
development discharge volume from exceeding the predevelopment
discharge volume for the 2‐year 24‐hour design storm; and
Incorporate riparian and wetland setbacks into the site development using
member community standards or as detailed in Appendix F, whichever is
more restrictive. If the applicant’s property does not contain wetlands or
watercourses, this requirement does not apply.
The applicant must show that the post‐development quantity (volume) from a 2‐
year 24‐hour storm event is equal to or less than the pre‐development values.
Hydrologic and hydraulic calculations are required to estimate the volumes, using
various methods and computer‐based software including the U.S. Natural
Resources Conservation Service (NRCS) methods for predicting runoff volumes.
Methods should include the development of pre‐ and post‐ developed
hydrographs to determine the runoff volume generated. Care should be taken not
to overestimate initial abstraction values when using the NRCS methodology.
2. Exceptional Runoff Volume Credit
A Stormwater Quantity Credit of 50% may be provided to applicants who:
Implement a stormwater management plan that prevents the developed
discharge volume from exceeding the undeveloped discharge volume for up
to a 100‐year 24‐hour design storm; and
NEORSD Stormwater Fee Credit Policy Manual January 2017
18
Incorporate riparian and wetland setbacks into the site development using
member community standards or as detailed in Appendix F, whichever is
more restrictive. If the applicant’s property does not contain wetlands or
watercourses, this requirement does not apply.
The applicant must show that the post‐development quantity (volume) from a
100‐year 24‐hour storm event is equal to or less than the pre‐development values.
For all sites, the pre‐developed condition for existing impervious surfaces shall be
defined as grassland in good hydrologic condition intending to mimic hydrological
conditions prior to any development. In effect, the applicant must be able to
demonstrate that stormwater runoff from their existing or proposed impervious
surfaces does not impact the Local Stormwater System or the Regional
Stormwater System, up to a 100‐year, 24‐hour storm, beyond the impact that
would occur from an undeveloped site.
Hydrologic and hydraulic calculations are required to estimate the volumes, using
various methods and computer‐based software including the U.S. Natural
Resources Conservation Service (NRCS) methods for predicting runoff volumes.
Methods should include the development of pre‐ and post‐ developed
hydrographs to determine the runoff volume generated.
C. Maintenance Requirements
1. SCMs
SCMs receiving the Stormwater Quantity Credit must be maintained by the
applicant, or one of the co‐applicants, to ensure continued function of the SCM.
NEORSD Stormwater Fee Credit Policy Manual January 2017
19
2. Responsibility
The applicant, or one of the co‐applicants, must have legal responsibility to
maintain the SCM. The recertification process will require documentation that the
SCM is continuing to function as originally intended.
3. Maintenance Plan
An inspection and maintenance plan is needed for all SCMs receiving the
Stormwater Quantity Credit. Implementation of the maintenance plan will be
required as part of the recertification of credits.
D. Restrictions
1. Eligible SCMs
Only those impervious surfaces of a particular site that drain through the
District‐approved SCM are eligible for credit.
2. Transfer of Credit
Stormwater fee credits do not transfer if property ownership changes. A
recertification and new general application must be submitted for properties
that have had a transfer of ownership.
In the case where multiple properties are covered under one credit
application, for example a Homeowners or Condominium Association, or
multiple commercial properties that drain to a single SCM, a recertification
and new general application must be submitted only if the property that has
maintenance responsibility for the SCM changes ownership.
3. Local Community Requirements
A stormwater fee credit is only available for SCMs that are installed and
maintained in compliance with all applicable local regulations of the member
community in which the property is located and are approved by the District.
4. Homeowners or Condominium Association

VII. Reduction of Impervious Surface
Account holders may reduce the amount of impervious surface on their property by the
installation of either a vegetated green roof or permeable pavement. If the proper
documentation is submitted to delineate the area of green roof and/or permeable
pavement, and to demonstrate that it was designed and installed correctly, then the area of
the green roof and/or permeable pavement will be removed from the parcel’s impervious
area calculation. Annual recertification must be submitted to document that the green roof
or permeable pavement still exists, and that it is being properly maintained.
Account holders may also reduce impervious area by demolition of structures or pavement
and replacement of the impervious surface with vegetation. Owners can request that the
impervious area be re‐delineated following the establishment of the vegetation. Areas that
are not brought to the Districts attention will be re‐delineated automatically during periodic
impervious surface evaluations. Once removed there is no further recertification required.
This is not considered a credit but rather a direct reduction in a properties impervious area.
A. Specific Application and Documentation Requirements

VIII. Education Credit
An Education Credit of 25% is available to public and private primary, elementary, and
secondary school account holders recognized by the State of Ohio that provide to their
students a regular and continuing program of education concentrating on stewardship of
our water resources and minimization of demand on the regional stormwater system. The
rationale behind this credit is that the curriculum provided by the institution will assist the
District in education regarding our regional stormwater‐related water quality and quantity
problems, and also instill an appreciation and stewardship of our water resources, providing
long‐term benefits and/or decreases in the demand on the regional stormwater system and
program.
This education must be provided annually to at least 25% of the grade levels across the
school or school district. An individual school may apply for the credit, or a school district
may apply on behalf of all its schools. The Education Credit may be combined with the
Stormwater Quantity and/or Quality Credits for a potential 100% credit for a particular
school property.
The Education Credit will apply for one full calendar year, and the credit period will begin
one full billing cycle after the credit application is received and approved. A final report
must be submitted at the end of the school year in which the curriculum was delivered. If
the final report is not received, or the requirements for the credit were not met, an
adjustment will be made on future bills to reimburse the District for the credited amount.
The District has identified three options for schools located within its stormwater service
area to obtain the Education Credit. Schools can select any one of the options to obtain the
credit. The three options for schools to obtain the Education Credit are as follows:
Option 1. Watershed Education Curriculum: The District will provide Watershed
Education Curriculum (WEC) materials that schools may use to obtain the Education
Credit. These materials will reflect the grade‐level Ohio Academic Content Standards
NEORSD Stormwater Fee Credit Policy Manual January 2017
39
and include specific outcomes. The District is providing materials for grade levels 3, 5,
7, and 10. Schools are encouraged to apply early but may submit an application as late
as December 31st of the current school year. To ensure availability of District provided
materials and manuals when school starts schools must apply for this option by June
1st of the preceding school year.
Final documentation to receive this Education Credit must include a sample of one
completed workbook per classroom, along with a final report. This documentation
must be received by the District no later than June 15th of the applicable school year.
The District will provide:
Credit application forms
Grade‐level curriculum and student workbooks
Teacher manuals
Final report form
As an example, if a school decides to participate in the 2016‐17 school year, the credit
application must be received by December 31, 2016. The workbook and teacher
manual would be delivered by August 1st of 2016 for those that apply by June 1st;
those that wait to apply are subject to material availability. The school must submit
the final report by June 15th of 2017. If all requirements are met, the credit will be
applied beginning with the first full billing cycle after the application is approved, and
will continue for a 12 month period.
Option 2. School Curriculum: Stormwater and watershed curriculum may be taught in
the classroom with curriculum developed by the school’s teachers in order to obtain
the Education Credit. The curriculum must be place‐based to ensure that students
understand the dynamics of stormwater and watersheds in their own community. A
minimum of 4 contact hours is required. To be approved for an Education Credit, the
submitted lesson plans must include at least 4 of the topics presented below.
NEORSD Stormwater Fee Credit Policy Manual January 2017
40
Target topics are:
The natural water cycle as well as the urban water cycle, including water and
wastewater treatment.
The watershed concept, stream formation, and causes of erosion and
flooding.
Effects of stormwater and surface water pollution on Northeast Ohio rivers,
streams, and Lake Erie.
Stormwater runoff pollution prevention.
Water conservation and its relevance in water‐rich Northeast Ohio.
Watershed management, topography and the geologic history of our region.
The function and ecosystem services provided by streams, wetlands, and
floodplains for flood control and erosion control.
To qualify for the credit through Option 2, the school or school district must provide
the required application forms, which will include a lesson plan form. The lesson plan
will include: objectives, activity (if applicable), and summary of the lesson with an
estimate of the number of students and grade level expected to receive the
curriculum during the school year. Lesson plans must be approved by the District.
Schools should submit applications and lesson plan(s) for this option from June 1st to
December 31st of the applicable school year to ensure review and acceptance of the
lesson plans.
Final documentation to receive this Education Credit will include a final report. This
documentation must be received by the District no later than June 15th of the
applicable school year.
The District will provide:
Credit application forms
Lesson plan form
Final report form
NEORSD Stormwater Fee Credit Policy Manual January 2017
41
As an example, if a school decides to participate in the 2016‐17 school year, the credit
application should be received by December 31st of 2016. The school must submit the
final report by June 15th of 2017. If all requirements are met, the credit will be applied
beginning with the first full billing cycle after the application is approved, and will
continue for a 12 month period.
Option 3. Informal Science Institution Program: Schools may elect to use District‐
approved programs that will be delivered by informal science institutions to satisfy the
requirements of the Education Credit. These institutions will be listed on the District
website with a description of the approved programs and associated contact hours.
Examples of institutions that might deliver curriculum include the Cleveland
Metroparks, Cuyahoga Soil and Water Conservation District, Doan Brook Watershed
Partnership and others. These programs will typically range in length from 1 – 4
contact hours the District website will identify the target topics that will be covered.
The Informal Science Institution Programs can assist schools in obtaining the
Education Credit by providing all or a portion of the required contact hours. If a
portion of the contact hours are provided by the informal science institution, the
school will be required to make up the difference of the required 4‐contact hours.
Examples:
A District approved program that provides the required 4‐contact hours for
the Education Credit is selected, delivered, and documented. This program
would satisfy the Education Credit requirement.
Select District approved program(s) that provide less than the required 4‐
contact hours will require supplemental classroom work. For example, a
program offered by the Cleveland Metroparks Watershed Stewardship
Center may provide only 2 contact hours, requiring the school to provide the
additional 2 hours of content to satisfy the Education Credit requirement.
NEORSD Stormwater Fee Credit Policy Manual January 2017

Examples of downspouts for vegetated filter strips
VEGETATED FILTER STRIPS are uniform strips of dense turf, meadow grasses, trees or other
vegetation with a minimum slope to treat the water flowing from impervious surfaces. In certain
circumstances a large lawn that receives runoff from impervious areas of a property may meet the
criteria for a grass filter strip.
installation standards:
To obtain an individual residential property credit for
vegetated filter strips the following criteria must be met:
a. 50% of the property’s roof area must drain to the
vegetated filter strip.
b. Runoff from downspouts must be dispersed using
splash block prior to reaching filter strip.
c. The slope of a vegetated filter strip must be greater
than 1% and less than 5%.
d. Filter strips must be fully vegetated, and vegetation
must be kept healthy.
e. Filter strips must have a minimum length of 50 feet,
but should be designed to provide a length based on
their slope within the ranges noted on the next page.
f. Filter strips must occur entirely on the applicant’s
property.
15
1. Maintain healthy vegetation along the filter strip. If
planted with grass, the height should be at least 3 to 4
inches.
2. If erosion occurs causing rills and gullies, repair and
stabilize.
3. Check splash blocks twice a year to make sure they
are not broken or deteriorating. Replace as needed.

fact sh e e t northeast ohio regional sewer districtresidential pervious pavement
perVious paVeMents are designed to allow
percolation or infiltration of stormwater through
the surface into the soil below where the water is
naturally filtered and pollutants are removed. pervious
pavement may include paving blocks, grid pavers,
pervious concrete, or pervious asphalt.
it is recommended that a qualified installer with
knowledge in hydrology and hydraulics be consulted
for applications using pervious pavement to ensure
desired results. this fact sheet provides an overview
of construction guidelines and research to date and
is not meant to replace the services of experienced,
professional installers.
to obtain an individual residential property credit for
pervious pavements the following criteria must be met:
a. installed for the purpose of runoff infiltration.
b. area of pervious pavement is at least 1,000 sq. ft.
c. used on slopes no greater than 4%.
d. the stone reservoir underneath the pavement type
must be at least 10 inches deep at all points.
e. the installation meets the local building and zoning
standards for driveway installations.
1. ensure pervious pavement system is draining,
and there are not visible signs of standing
water on surface.
2. remove accumulated salt on surface during
winter months.
3. Vacuum as necessary to remove sediment
accumulation and organic debris on the
pavement surface.
4. remove accumulated leaves and debris from

fact sh e e t northeast ohio regional sewer district residential on-site stormwater storage structures
on-site storMwater storage struCtures can include rain barrels, cisterns, bladders, or other
storage devices as approved by the Northeast Ohio Regional Sewer District. these structures
collect and capture rooftop rainwater that would otherwise drain directly to the stormwater system or
streams. the collected stormwater can be used to water plants, trees, or lawns during dry periods.
a rain barrel is composed of a 40-55 gallon barrel or
drum with some type of diverter or connection from a
downspout, a spigot or hose to drain the barrel, and some
type of overflow mechanism. any openings to the air
should be screened to keep debris and insects out.
an overflow mechanism must be provided so that when
the rain barrel is full, excess
water can flow back into
the downspout and then
to a storm sewer, or into a
landscaped area.
saving water not only helps
protect the environment it
saves money and energy
because of the decreased
demand for treated tap
water. Check with your
County soil and water
Conservation district or
local watershed group for
instructions on how to make
and install a rain barrel.
rain barrels can also be
purchased through several online suppliers. ensure your
rain barrel will meet the requirements on the next page.
rain barrel:
Example of rain barrel
with downspout
diverter that directs
overflow back to the
downspout
Cisterns are similar to
rain barrels in function
but hold larger quantities
of water. they can be
installed underground, at
ground level, or elevated
depending on the site
and space constraints of
the property.
a cistern should be
constructed out of
reinforced concrete, galvanized steel, or plastic,
and should have smooth interior surfaces, be
watertight, have enclosed lids and be sized
according to the installation standards on the next
page to manage the proper amount of runoff.
cistern:
Example of Cistern
(Cleve. Metroparks Zoo)
a rain bladder is a flexible modular tank
designed to be installed into the tightest
locations and can be
completely hidden
from view. they can be
installed under the sub-
floor of a home, gazebo,
and under decking.

include a sketch or a photo of their stormwater
control measure. applications are available at
neorsd.org/stormwater or by calling Customer
service at 216.881.8247.
to apply:
to obtain an individual residential property credit for
onsite stormwater storage the following standards and
requirements must be met:
1. 50% of the property’s roof area is properly
connected to rain barrels or other approved storage
devices that provide at least 40 gallons of storage
per downspout,
- or -
storage structures must be sized to hold the runoff
from at least 50% of the property’s roof area during a
1-inch rainfall event.
V = ½ x a x 0.6225 gallons/feet2
where:
V = volume of storage structure in gallons
a = total surface area of roof in square feet
0.6225 = conversion factor (gallons per cubic foot
per inch of rain)
Example
a 500-gallon cistern would provide runoff
storage from a 1,600-square-foot rooftop for a
one-inch rainfall.
a = 1,600 square feet
½ x 1,600 x 0.6225 = 498 gallons
2. onsite stormwater storage must be completed
in such a way that does not provide mosquito
breeding grounds, such as making sure rain barrels
are covered with a lid or screen that prevents
mosquitoes from entering the storage structure.
3. onsite stormwater storage must be equipped
with an overflow or bypass mechanism to divert
rainwater to the storm drainage systems when
storage structure is full. these mechanisms must not
cause erosion, property damage or overflow onto a
neighboring property.
4. onsite stormwater storage must be completely
drained in no less than 24 hours and no longer than
4 days after each rainfall event.
5. all on-site stormwater storage structures must meet
the requirements of member community building
and zoning codes for downspout disconnection,
landscaping, property setbacks, and other
applicable local codes.
installation standards:
1. Clean your gutters regularly to reduce debris.
2. Clear off any screens as necessary.
3. periodically check any hoses associated with the
storage structure to clear any debris.
4. to winterize, disconnect and return the downspout
to its original configuration. remove the hoses
and mesh screen and store them. Make sure to
drain the container to prevent it from freezing and
cracking. if possible, store it upside down, so no
water or materials will be able to enter.
5. for cisterns, leave the outflow spigot fully open
during frost/freezing periods and unhook the
drain hose about twice a year to clean out any
compacted sediment.

Appendix F: Riparian and Wetland Setback Requirements
Applicants for the Runoff Volume Credit must decrease the rate and quantity of stormwater runoff. If a
wetland or watercourse is on the applicant's property, the applicant must incorporate riparian and wetland
setbacks from all watercourses and Ohio EPA Category 2 and 3 wetlands. These setback requirements for
receiving a credit pertain to all soil-disturbing activities, including the location of the stormwater control
measures for which the applicant is seeking the Runoff Volume Credit.
• For sites with greater than 50% impervious surface (as defined in Section 3.B): 25 foot setback for all
watercourses and category 2 and 3 wetlands.
• For sites with 50% or less impervious surface (as defined in Section 3.B): the following setback widths
are required.
The riparian and wetland setback delineation must follow the more stringent of either the member
community regulations or the following requirements:
• Watercourse - Means any brook, channel, creek, river, or stream, either continuous or intermittent,
having an established, and defined bed and bank, as determined by the ordinary high water mark, and
definite direction of flow.
• Wetland - means those areas that are inundated or saturated by surface or ground water at a frequency
and duration sufficient to support, and that under normal circumstances do support, a prevalence of
vegetation typically adapted for life in saturated soil conditions, including swamps, marshes, bogs, and
similar areas. (40 C.F.R. 232, as amended).
A. Riparian setback are measured in a horizontal distance from the ordinary high water mark of a
watercourse at the following widths:
B. Wetland setbacks are measured in a perpendicular direction from the defined wetland boundary.
Wetland setbacks widths are as follows:
C. The following conditions also apply to riparian and wetland setbacks:
