STORMWATER RATE PROPOSAL
P.O.- 1
INTRODUCTION
The Metropolitan St. Louis Sewer District (MSD or District) was formed on February 9, 1954,
when voters approved the Plan of the District (Charter) to provide a metropolitan-wide system of
wastewater and stormwater facilities. MSD began operations in January 1956 in an area roughly
composed of the City of St. Louis and the portion of St. Louis County located east of Interstate
270. MSD took over the publicly-owned wastewater and stormwater drainage facilities within its
jurisdiction and began the construction of an extensive system of collector and interceptor sewers
and treatment facilities. Most of the remainder of St. Louis County was annexed by MSD in
1977.
MSD’s Rate Commission was established in 2000. The Commission consists of 15 member
organizations that represent a broad cross-section of the customers and community MSD serves.
The Commission’s purpose is to provide public input into how MSD sets its rates. The
Commission is required by Charter to review all Rate Proposals and render an opinion before
submitting Rate Proposals to the Board of Trustees for approval.
The Rate Commission process includes multiple public hearings throughout the St. Louis
metropolitan area where MSD customers have an opportunity to provide feedback on the Rate
Proposal. The entire Rate Commission proceedings may take up to 165 days from the date the
District submits a Rate Proposal for consideration. All Rate Commission meetings are open to
the public. The date, time and location of Rate Commission meetings and Public Hearings will
be posted on the MSD website.
This Rate Proposal seeks to establish a stormwater capital rate to provide funding for capital
improvements to address flooding and erosion. The Proposal is the product of the District and is
based on the strategic and financial implications of its Stormwater (SW) service obligations to
the St. Louis region. The District’s development of its Rate Proposal reflects consultative and
analytical assistance from Raftelis Financial Consultants, Inc. (RFC).

EXECUTIVE SUMMARY
3.1 Existing Billing Structures
On April 5, 2016, an election was held in which 62% of voters in the District’s service area
approved Proposition S. The approval of Proposition S provided that all District customers
would be assessed a uniform property tax rate to pay for SW O&M service and, in turn, all
District customers would receive the same level of SW O&M service. The implementation of
Proposition S occurred gradually throughout Fiscal Year 2017. Proposition S allowed the
District to rollback and eliminate several existing taxes; eliminate the SW fee ($.24 per month
per residential and non-residential customer and $.18 per multi-family unit); and, in lieu of these
funding mechanisms, institute or leave in place two taxes that cover the District’s entire service
area. These two taxes consist of a $.02 per hundred dollars of assessed value property tax (2 cent
tax)1 intended to pay for SW regulatory-related expenses and a $.10 per hundred dollars of
assessed value property tax (10 cent tax)2 intended primarily to pay for O&M of the public SW
system. There currently is no dedicated source for the stormwater capital improvements needed
within the district.
1 Exact assessment is currently $.0188 per $100 of assessed value owing to adjustments in the tax rate since it was
initially set.
2 Exact assessment is currently $.0971 per $100 of assessed value owing to adjustment in the tax rate since it was
initially set.

3.2 Proposed Billing Structure
The District is proposing the addition of an impervious area-based SW capital rate to fund capital
improvements needed throughout the District’s service area. The RC in its report dated July 30,
2015 found, “that a stormwater rate change proposal which charges customers an established rate
times the quantity of impervious area of their property to fund stormwater operations does
impose a fair and reasonable burden on all classes of ratepayers.” Based on this finding they
recommended the District consider an impervious area based rate.
For most of its history, MSD had no funding to provide meaningful SW services. In 2008, the
RC recommended and MSD implemented the (impervious area-based) SW User Charge, which
funded all SW services (regulatory, O&M, and capital) and, if fully implemented, would have
raised approximately $81 million annually. In 2010, the SW User Charge was held invalid. In
2015, the RC recommended and the voters later approved the ten-cent SW O&M property tax to
go along with the existing two cent tax which is used to fund SW Regulatory activities. Now, in
this Rate Proposal, MSD seeks a funding source for the final piece of the SW funding puzzle –
the SW capital rate to fund capital improvements primarily for flooding and erosion control.
3.3 SW Rate Proposal
The District’s proposed SW rates are based on rate design application and analysis conducted by
MSD’s rate consultant, RFC, in conjunction with District staff. The principal assumptions used
in the SW Rate Proposal are as follows:
1. RFC has relied on certain historical, financial and statistical data supplied by District staff.
While such data is considered reliable, RFC has not independently verified or audited the
detailed accuracy of such data.
2. Total billable impervious area will increase slightly over the forecast period as projected by
District staff based on historical trends.
3. Total taxable assessed property value will increase slightly over the forecast period as
projected by District staff.
4. The District’s SW expense will have inflationary increases over the forecast period as
shown in Section 4 of this Rate Proposal.
5. The District’s estimates of content, scheduling and cost of the five-year SW CIRP present a
reasonable projection of the future construction program. More details about the District’s
SW CIRP can be found in Appendix D of this Rate Proposal. The SW CIRP is funded
without the use of debt.

6. The District proposes incentives and credits to promote development and customer
improvements that will decrease the demand placed upon the District’s system by SW
customers. These incentives and credits are discussed in Section 4.4 of this Rate Proposal.
The financial plan for the proposed stormwater capital rate is shown in Table 3-1. The proposed
financial plan assumes that the proposed stormwater capital rate would be set at two-thirds of the
approved level for FY 2020 and 2021. This ramp-up is based on the lower revenue requirement
of the first two years as the program is implemented and necessary personnel and projects are
added before the rate is charged at approved levels beginning in FY 2022.
To support this timeline the District expects to present the proposed rate to the voters of the
District for their consideration in April of 2019, and if approved the stormwater capital rate
would be effective beginning January 1, 2020.

PROPOSED STORMWATER FUNDING
MSD proposes the use of a Districtwide SW capital rate primarily to fund projects to address
flooding and erosion control.
4.1 Stormwater Revenue Requirements
The revenue required to provide for the continued operations of the District’s SW utility must be
sufficient to meet its cash requirements for system operation. Revenue requirements include (1)
regulatory expenses; (2) total SW system O&M expenses; (3) expenditures for capital
improvements, particularly deferred capital; and (4) provision for an adequate operating reserve.
4.1.1 Stormwater Regulatory Services
MSD has certain regulatory obligations it must comply with to meet SW quality requirements
outlined by federal and state statutes and regulations. The District is the lead co-permittee in an
MS4 permit for the St. Louis region. Under this permit, MSD must implement Best
Management Practices (BMP) to address SW quality issues. MSD is required to have a public
education and outreach program, an illicit discharge detection and elimination program, and a
SW pollution prevention program. MSD and the co-permittees are also required to regulate and
enforce the construction and continued maintenance of water quality features (Stormwater BMP)
to control pollutants in SW runoff from development projects both during and after construction
is complete. The 2 cent tax levied by the District provides adequate funding to meet MSD’s
current regulatory obligations. Whether or not this Rate Proposal is implemented, this tax will
remain in place to fund these services.
4.1.2 Stormwater Operation and Maintenance Expense
Revenue collected from the existing 10 cent tax is available to fund SW related O&M
expenditures. These activities include removing blockages, open channel cleaning, repair of
storm sewer line failures, and limited inlet inspections and cleanings.
The FY18 adopted budget is the basis for projecting the majority of existing SW O&M expenses
and is adjusted for the same inflation and growth factors as other MSD O&M expenses. Some
Engineering and Operations expenses were forecasted in FY18 based on new information. Table
4-1 shows FY18 SW expenditures to be $35.4 million. The policy for how the SW utility is
operated and maintained is contained in Exhibit MSD 23.

Table 4-1 – Stormwater Expenditures
4.1.3 Stormwater Capital Improvement Program
The SW CIRP outlined in this proposal is comprised of three major categories. The proposed
SW capital rate would fund approximately $30 million of capital expenditures annually to
address flooding and erosion. The two remaining categories are paid for with existing fund
balances in OMCI funds and a small percentage of the 10 cent tax revenue. These two categories
represent the approximately $67 million3of projects identified in the February 2015 Rate Change
Proposal. Once the OMCI funds’ balances are fully depleted and the projects identified to be
funded from the 10 cent tax revenue are completed, no funding source will be available for SW
CIRP without approval of the proposed SW capital rate.

4.1.4 Operating Reserve
The SW operating reserve is necessary to provide protection for unplanned expenses. Under the
existing funding mechanism, SW revenues are collected from Ad Valorem Taxes which are
collected annually in the City and County. Due to this annual revenue collection schedule, it is
necessary for the SW fund to maintain a reserve balance that provides sufficient working capital
to meet the regular operating expenses in the first six months of a fiscal year after which a new
year’s revenues will be collected. The District targets an operating reserve equal to 240 days of
SW O&M expense in the existing Regulatory and Districtwide Stormwater funds. The existing
OMCI funds do not have a minimum reserve requirement as it is intended to completely spend
those funds down as projects in each OMCI area are undertaken. The proposed SW capital rate
fund does not have a fund balance requirement because it will be used to fund capital projects as
funds are available.

4.2 Existing Stormwater Funding Methods
The District currently has three existing funds for SW related activities: the OMCI Funds,
Regulatory Fund, and O&M Funds.
4.2.1 OMCI Funds
The OMCI Funds’ ad valorem taxes were previously collected from specific service areas within
the District to fund projects within those specific service areas. With Proposition S these tax
rates were all set to zero and the District intends to spend these funds down over time on projects
within the service areas from which they were collected. Table 4-2 shows recent and projected
revenues and expenditures from these funds.
Table 4-2 –OMCI Funds
4.2.2 Regulatory Fund (2 cent tax)
The Regulatory Fund is funded by the 2 cent SW regulatory property tax. This fund is intended
to fund regulatory activities related to SW throughout the District’s service area and is collected
from all properties within the District’s service area. Table 4-3 shows recent and projected
revenues and expenditures from this fund.

4.2.3 Districtwide Stormwater Fund (10 cent tax)
The Districtwide Stormwater Fund for O&M is currently funded by the 10 cent tax approved
under Proposition S in April 2016. The existing fund balance shown at the beginning of FY
2017 was collected from the previous tax levy that was repealed by Proposition S and is now
used to fund O&M expenses within the areas they were collected. The current tax levy is
assessed to most properties within the service area, however those properties within certain levee
districts are excluded because those levee districts provide the SW services that would otherwise
be paid for by this fund (see section 4.5 for additional information). Table 4-4 shows recent and
projected revenues and expenditures from this fund.

STORMWATER RATE PROPOSAL

4.3 Proposed SW Capital Rate
This Rate Proposal supports implementing a stormwater capital rate if approved by the voters of
the District. This stormwater capital rate would be used to fund capital improvements primarily
to address flooding and erosion control in the SW system.
The stormwater capital rate will be determined based on the amount of each customer’s
impervious area. Charging for SW service based on impervious area is a common methodology
used by utilities throughout the United States and was recommended by the RC in its
Recommendation Report dated July 30, 2015. A more detailed description of how impervious
area is determined for each customer is provided in Appendix A.
The proposed rate was determined based on the recommended capital improvement program
divided by the estimated units of service in the District’s service area. Single family residential
customers’ impervious area will be measured and charged on a tiered basis. Proposed square
footage tiers can be found in Table 4-5. Non-residential customers’ impervious area will be
measured and customers will be charged based on units of 2,600 square feet, which is the amount
of an ERU, the impervious area on a typical single family residential lot. The proposed basic rate
will be $2.25 per ERU. The District intends to only charge two-thirds of the voter approved rate
for the first eighteen months starting January 1, 2020 as the District ramps up the program.
The District’s existing Customer Assistance Program will be available for the impervious area
SW rate and provides a 50% reduction on eligible customers’ bills. A more detailed description
of the Customer Assistance Program is provided in Appendix F.
The proposed capital improvements to be funded by this rate will address local flooding, regional
flooding, and erosion within the District.
Table 4-6 shows projected revenues and expenditures from this fund.

4.4 Proposed Incentive Programs
Programs across the country that employ impervious area-based rates often provide customers
with incentive programs for reducing their effective impervious area through the use of
constructed features or low impact development. The RC supported the District’s consideration
and use of such incentives in its July 30, 2015 recommendation report. The following incentives
are proposed to complement the proposed stormwater capital rate.
4.4.1 Residential Incentive Program
The District will provide a one-time reimbursement to customers for Best Management Practices
(BMPs) implemented such as rain gardens or cisterns. The runoff from a minimum of 500
square feet of impervious area would have to be captured by the BMP. The incentive will be
based on 50% of the average residential bill over a 10-year time period. A condition of the
incentive is that the facility not be a municipal separate storm sewer system (MS4) permit
regulated requirement. Customers must be current on their MSD bill to receive the incentive.
4.4.2 Commercial Incentive Program
A 50% credit for SW BMPs will be provided for impervious areas tributary to Volume Reducing
Green Infrastructure (designed to mimic runoff from green areas), and for detention basins
meeting the current channel protection criteria (1-year design storm). Designs would have to
meet current MSD design standards, and the 50% credit would be applied to the percentage of
impervious area tributary to the facility. The credit will only be applied to the service area that
was modified which resulted in the reduced stormwater run-off. The credit will be a renewable
5-year credit, subject to the customer re-applying for the credit. A condition of the credit is that
the facility not be an MS4 regulated requirement.

4.4.3 Other Incentive Programs
The District will also recognize customers that have less impact on the District’s SW system
owing to their development characteristics. A customer can only qualify for one of the following
incentives or credits.
4.4.3.1 Best Management Practices Incentive Program
Constructed SW BMPs that are designed to be pervious will be 100% excluded from the billable
area. Examples include green roofs and pervious pavement. If aerial photography identifies
these areas as impervious, the customer will need to apply for this 100% billing adjustment. A
minimum of 1 ERU must be removed.
4.4.3.2 Low Impact Development Credit Program
A 35% billing credit will be given to customers for whom the impervious surface area is less
than 15% of the gross surface area for a parcel or contiguous parcels, equivalent to
Environmentally Sensitive Development. Eligibility will be limited to customers with a lot size
of 3 acres or more.
4.4.3.3 Direct Drainage Credit Program
A 70% credit will be available to those customers whose stormwater drains directly to a large
river (Missouri, Mississippi, or Meramec) or other equivalent situations
4.5 Levee Districts
The rate proposal recommends that Levee Districts currently under agreements with MSD4 be
exempt from the proposed SW capital rate. The Levee Districts possess, pursuant to statutory
authority, the responsibility to provide stormwater services within their respective service areas,
including capital improvements to address flooding and erosion. Accordingly, MSD will not
charge the SW capital rate within the Levee Districts. With that, as was previously agreed to,
MSD and the Levee Districts will continue agreements (See Exhibit MSD 13 for Levee District
Agreements) that outline these responsibilities. The current agreements require MSD to provide
only certain regulatory services within the Levee Districts. Revenues to cover this regulatory
expense will be from the continuation of the regulatory tax currently assessed throughout the
MSD service area, including the Levee Districts.
4 All levee districts in MSD’s service area except Missouri Bottoms-Hazelwood Levee District have entered into an
agreement with the District. Customers in the Missouri Bottoms-Hazelwood Levee District pay the 10 cent tax and
would pay the proposed stormwater capital rate.

5.1 OVERALL CUSTOMER IMPACTS
The District must generate annual revenues that are sufficient to meet the current operating,
capital, and financial policy requirements to support the SW service levels. Section 4 has
identified the SW ad valorem taxes and proposed SW capital rate that are sufficient to meet the
District’s needs. SW tax impacts are based on a typical property value for a given customer class
from property tax records. Volumetric charges are based on average historical usage for a given
customer class, and impervious area for residential is based on 1 ERU while for non-residential it
is based on 16 ERU, the average for the class. Typical assessed values are based on analysis of
property tax records and MSD billing data for these customer classes.

A. Impervious Area Determination
Building an impervious surface dataset that can be used for billing purposes is a process that
begins with Aerial Photography (See Figure 1). Aerial Photography must be flown before an
impervious surface can be captured. This flight is always scheduled at the beginning of the year
when the leaves are off the trees allowing
technicians more visibility when looking for
impervious surfaces. The photographs are
also taken orthogonally, or at a 90-degree
angle to the earth, to ensure proper
perspective for area measurements. Once
flown, technicians begin to use the imagery
to visually identify and draw every
impervious surface by hand. A technique
called Stereoscopy is used to make such
surfaces and buildings appear three
dimensional allowing the technician to
capture them more accurately. MSD had the
impervious surfaces captured this way for the
2005 data, but since has used an updating
process as it is quicker and more cost
effective. The updating process consists of using the existing impervious surfaces and
comparing them to new aerial imagery, collecting only what has changed. The impervious
surfaces were updated in 2007, 2009, and 2012.
During the original capture and subsequent
updates to the impervious surfaces,
technicians classify data as they capture it.
Each impervious surface is given a
classification based on what it is that
distinguishes it from other impervious
surfaces. Some of the different classes used
include: Building-Main Structure, Road-
Paved, Driveway, Sidewalks Private, and
Sidewalks Public to name a few.
Impervious surface boundaries are combined
with Parcel boundaries (See Figure 2) to
determine the impervious area within each
customer’s parcel and thus determine the
dollar amount each customer is billed. The
City and County of St. Louis each maintain their own Parcel Base. MSD obtains the two Parcel
Bases and stitches them together into a single Parcel Base, taking care to remove any overlaps.
This precludes the possibility of double billing a customer.
Figure 1
Figure2
SECTION 6: Appendices
Metropolitan St. Louis Sewer District
STORMWATER RATE PROPOSAL
6-3
The two basic datasets used in impervious surface billing - impervious surface boundaries with
their various classifications, and an integrated Parcel Base, are then processed by MSD to
develop a ‘billable’ impervious surface area for each customer. Impervious surfaces such as
roads and sidewalks in public areas and right-of-ways are removed because they cannot be
attributed to a particular customer since they are for public use and/or not located on a parcel
assigned individual ownership. Figure 3 shows an aerial photo with the parcel base and
classified impervious surfaces. Red indicates a main building, green is driveways, blue is patios,
and yellow is private sidewalks. For the updated impervious datasets, following the original
capture, the process must also take “Status” into account. During the update process, all
impervious surfaces are assigned a status of Existing, Modified, New, or Deleted. All surfaces
with a status of Deleted are then left out of calculations moving forward. Next, all impervious
surfaces that exist outside of a parcel in the right of way are clipped off to be removed.
The process then looks at the underlying
parcel data for the rest of the impervious
areas and determines with its land use code
if the parcel is residential or not. The parcel
information that MSD receives does not
always align with impervious surfaces so
efforts are made to ensure the data is
correctly handled for billing purposes. For
example, residential properties are typically
located within property lines. Therefore, in
the event that a home or driveway is shown
slightly crossing a property line, the
impervious surface will be assigned to the
parcel where it has the greatest overlap.
The parcels are not adjusted because MSD
does not own that data and leaves the
maintenance to the St. Louis City and County. Because nonresidential scenarios can vary so
greatly, all impervious surfaces on them are split on the property line. As both residential and
nonresidential impervious surfaces are being processed, they are assigned the Parcel
Identification Number (PIN) of the parcel they sit on. This final set of impervious surfaces that
have been clipped, and assigned the proper attributes is called Assigned Impervious. Using this
data, impervious area totals can be figured for every customer and provided to billing.

C. CIRP Appropriation Adjustments
The project list that makes up the stormwater CIRP budget over this period consists of projects
needed to meet the region’s needs to provide proper stormwater runoff management. MSD
monitors the District’s watersheds and maintains a customer service and managed maintenance
system that records customer complaints. Based on this information, MSD then identifies
projects to address stormwater problem areas. The current database of unfunded projects
currently includes 483 projects with a conceptual cost estimate of $562 million in the following
categories: regional flooding, local flooding, erosion, and other types of projects.
To initiate the rate case preparation, Engineering provides Finance with a project list, including
estimated budget costs, as well as cost summary schedules that group projects in multiple ways.
The first grouping is by funding source; taxes, fund balance or capital rate. The estimated costs
are further broken down depending on whether they are for engineering or construction services.
These summary numbers are then adjusted for three different factors.
The first adjustment involves inflating estimated costs to account for price increases between
now and the time the project starts. The Engineering News-Record 5 was the source for inflation
assumptions related to the CIRP. They provide, on their website, a city construction cost index
for their subscribers. The average annual construction inflation rate for the 12-months ended
April 30, 2017, in the St. Louis area is 3.7%. That rate was employed in the rate modeling
process to annually inflate project cost estimates from fiscal year 2018 dollars.
The second adjustment performed on the CIRP estimates accounts for delays in appropriation
timing that can occur, due to such factors as the easement acquisition process or condemnation.
Capital program appropriations are spread throughout the fiscal year, as it is impractical to
deliver the entire annual program immediately at the start of the fiscal year. When delays occur,
some appropriations will shift from one fiscal year to the next. Appropriations during the three
most recent years averaged 89% of the annual budgeted appropriations. Using this 89% factor,
an appropriation delay was introduced into the numbers. The inflated costs for any given year
were reduced by 11%, and that 11% was shifted into the next fiscal year, thus reducing the total
expected appropriations slightly over the course of the five-year rate cycle.
Finally, it is common for projects to finish with some of the appropriation left unspent. We refer
to these dollars which are returned to fund balance as liquidations. Liquidations occur if projects
do not need to utilize their full utility relocation allowance, if the full budget contingency for
change orders is unused, or if final in place quantities of constructed items are less than bid

estimates. An analysis of completed projects revealed that on average, 9.5% of a project’s
appropriation is liquidated at the end of the project. While the timing of these liquidations vary
from project to project, it is common for these liquidations to occur approximately three years
after the appropriation. Therefore, projected appropriations in each year were decreased by 9.5%
of appropriations three years prior.
After inflation, appropriation delays, and liquidations, the resulting stormwater program is
valued at $115,554,865 over five years. This number is higher than the base projection of
$110,033,002 by 5.0%.

City Cost Index - St Louis - As of April 2017
The building and construction cost indexes for ENR's individual cities use the same components
and weighting as those for the 20-city national indexes. The city indexes use local prices for
portland cement and 2 X 4 lumber and the national average price for structural steel. The city's
CCI uses the same union wages for laborers.

D. CIRP Description
The stormwater CIRP is primarily made up of projects identified from historical records and
previous engineering studies to address customer complaints about flooding and erosion.
Currently, the stormwater CIRP consists of 483 projects to address flooding and erosion issues.
The projects identified will require approximately $562 million dollars to complete. Additional
projects will be identified as the CIRP proceeds.
Identified projects are segmented into three main categories: local flooding, regional flooding
and erosion. A breakdown of projects and their conceptual costs are included in the following
table.
Note: Percentages in table do not add up exactly due to rounding,
These categories of stormwater projects address the predominant public complaints and level of
service that MSD attempts to address with our current capital program. Regional flooding is
large scale flooding in locations of major creeks and rivers. Local flooding is small scale
flooding caused by overland flow of stormwater or small creeks. Erosion is the loosening and
washing away of soil due to the actions of water, usually adjacent to creeks and rivers. Presently
there are a handful of storm system maintenance related projects identified.
More specifically, types of stormwater flooding problems listed in order of severity include:
structure flooding, roadway flooding, and yard flooding. Types of erosion problems listed in
order of severity include: stream erosion threatening a structure, stream erosion threatening a
road, and yard erosion. These problems are addressed by projects that may require design and
construction of new storm sewer systems, storm system upgrades, storm system extensions,
stormwater detention, property buyouts, channel protection and restoration, or green
infrastructure improvements.

Projects are scheduled to build the highest priority projects first. Project scheduling is identified
through standardized calculations involving quantification of the severity of the problem and the
conceptual cost of the project.
The cost estimates that the CIRP budget is based on are conceptual in nature and are in fiscal
year 2018 dollars. A number of years ago, MSD reviewed the entire stormwater list to validate
projects and update estimated conceptual costs. The current project list is based on a minimal
amount of detailed information available regarding geotechnical conditions, utility relocation
requirements, easement requirements, and other site-specific issues that have the potential to
significantly affect the project’s eventual construction cost. As projects proceed through design,
these issues are fully evaluated and their impacts are incorporated into final design cost
estimates, which are reflected annually in the District’s budget supplement, which details the
capital program anticipated for the next fiscal year. The CIRP includes proposed expenditures
for contracted planning and design services, property and easement acquisition, and construction.
The complete CIRP plan is detailed in Table CIRP-1. Table CIRP-2 is a subset of CIRP-1, lists
only currently anticipated construction projects, and identifies the category of concern being
addressed (erosion, local flooding, or regional flooding).

E. Bad Debt and Revenue Collection
In order to account for uncollectible WW revenue, the District makes a monthly entry to write
off a certain percentage of WW billed revenue. This bad debt percentage is calculated based on
actual historical revenue collection percentages and then applied to the billed revenue. For the
proposed SW capital rate, the District decided to apply this same bad debt percentage for all
existing customers. This is because the additional SW capital rate will simply be added on to
their standard monthly invoice.
Within the District boundaries there are an estimated 40,000 customers to which the District
currently does not provide WW service, but which do have impervious area (example: parking
lots or homes with septic tanks). When the District begins billing the proposed impervious area
rate these will be considered SW only customers. The District is projecting an increased bad
debt percentage for these customers based on average collection data from similar utilities6 with
similar situations. See Table E-1 for weighted average SW capital rate bad debt calculation of
both existing and SW only customers.
Table E-1 – Calculation of Overall Bad Debt Percentage
Collection Process
The District’s collection process begins when an account is 25 days past due. Automated calls
are used with progressively more stern messages as the account approaches the 60 day past due
mark. The messages and timing of the calls are also adjusted based on that individual customer’s
propensity to pay. Working with our billing software and call center provider, the District
developed two predictive data models that predict the likelihood of a customer to pay back debt.
The commercial model uses 12 variables and the residential model uses 8 variables that proved
to be good predictors of a customer’s likelihood to pay. The following table shows the
progression of calls for a commercial customer based on number of days delinquent and
propensity to pay.
6 Information from Northeast Ohio Regional Sewer District (Cleveland area) and City of Philadelphia was available
for stormwater only customers.

rate (see MSD Exhibit 15). Eligible customers will receive a 50% reduction in their monthly
MSD WW and SW charges, and an opportunity to establish reasonable payment arrangements
for any outstanding delinquent balances. During the last WW Rate Proposal, District staff
projected the number of CAP customers to be 5,230 by the fiscal year 2020. The District is
currently on track to meet this projection.

vehicles. Elderly and disabled individuals are excluded from this eligibility criterion.
Customers must own or reside as a tenant in the property full-time. Property can be a
single family or multi-unit property (up to six units). The service name on the MSD
account must be the property owner or applicant name.
Addressing Outstanding Delinquency at time of Enrollment
New customers to CAP that have an existing outstanding balance greater than 30 days at
time of enrollment will be considered to receive a one-time adjustment of the following:
100% of accrued late charges, 50% of delinquent service charges and 50% of any
outstanding fees added to the account.
Customer must make payment arrangements on remaining outstanding balance based on
current payment arrangement guidelines.
Maintaining CAP Eligibility
Eligibility must be established every two (2) years effective March 1, 2018.
If found ineligible or customer does not reapply, rate reduction discount will cease with
the next month following annual renewal date. Standard MSD rates will apply.
Customers must remain current on all future reduced rate charges.
Non-payment may result in collection efforts and/or removal from Customer Assistance
Program.

H. Proposed Stormwater Policy
The existing Stormwater Policy is contained in Exhibit MSD 23. If the proposed stormwater
capital rate is approved Section 3.5 of the Stormwater Policy would be revised as shown below.
3.5 Capital Improvement Projects: MSD maintains a District-wide revenue source for the
funding of stormwater capital improvement projects. The stormwater Capital Improvement
and Replacement Program (CIRP) is made up of projects identified from historical records
and engineering studies to address flooding and erosion issues reported to and confirmed by
the District. Identified projects are segmented into three main categories: Local Flooding,
Regional Flooding, and Erosion. More specifically, types of stormwater flooding problems
listed in order of severity include but are not limited to: structure flooding, roadway
flooding, and yard flooding. Types of erosion problems listed in order of severity include but
are not limited to: stream erosion threatening a structure, stream erosion threatening a road,
and yard erosion. As projects are identified, these severity categories are used to prioritize
the projects. Project solutions may include the design and construction of new storm sewer
systems, storm system upgrades, storm system extensions, stormwater detention, property
buyouts, channel protection and restoration, or green infrastructure improvements. Projects
are implemented annually based on priority and availability of funds.

I. Property Tax Alternative
To generate the same amount of revenue in FY 2022 from a property tax instead of the proposed
impervious area based SW Capital Rate a property tax of $.0998 per $100 of assessed value
would need to be approved by the District voters.

J. Analysis of Proposed Stormwater Incentives and Credits
Residential
MSD would provide a one-time reimbursement for stormwater volume reducing best
management practices (BMP’s) implemented such as rain gardens or cisterns. Other equivalent
terms for this stormwater management technology include green infrastructure (GI) and
rainscaping. A minimum of 500 square feet of impervious area stormwater would have to be
captured by the volume reducing BMP. The rationale for a minimum area would be to minimize
the relatively high administrative burden for very small volumes of stormwater that will be
mitigated. The incentive will be based on 50% of the average residential bill over a 10 year time
period; therefore, the amount of the incentive could change depending on the size of the capital
program that is selected. A condition of the incentive is that the facility not be an MS4 regulated
requirement. Customers must be current on their wastewater bill to receive the incentive. The
50% credit maximum was established to account for the fact that 30% of a customer’s bill is due
to transportation related impervious surfaces in rights-of-way, plus the fact that stormwater
BMPs cannot perfectly match the natural water balance, but, rather mitigates impervious area. In
addition, the proposed credit is paid by MSD as an incentive up front, rather than after or while
the benefits accrue from the constructed BMP.
Anticipated forecasting for revenue impacts relies upon MSD’s other experiences with regard to
voluntary residential installation of BMPs in our CSO Rainscaping program, part of a consent
decree requirement. To date, after several years of implementation, 200 customers have installed
rain gardens under Project Clear, where MSD paid up to $3,000 of the cost. Considering a
typical residential bill will be $2.25 per month, or $27 per year, then 50% of the bill over 10
years would equate to an incentive of $135. Considering installation costs and the customer’s
greater share, it is anticipated the voluntary participation for stormwater credits would not exceed
the current number of participants. Assuming 50 customers per year at $135 incentive each, the
annual incentive program cost would be $6,750.
Commercial
A 50% credit for stormwater management practices will be provided for impervious areas
tributary to stormwater volume reducing BMPs (designed to mimic runoff from green areas), and
for detention basins meeting the current channel protection criteria (1 year design storm).
Designs would have to meet current MSD Design standards, and the 50% credit would be
applied to the percentage of impervious area tributary to the facility. The credit would only be
applied to the service area that was modified which resulted in the reduced stormwater run-off.
The credit would be a renewable 5 year credit, subject to the customer re-applying for the credit.
A condition of the credit is that the facility not be an MS4 regulated requirement.

For credit forecasting purposes, the best reference would be in regard to the MSD’s CSO
Volume Reduction Green Infrastructure Program or Large Rainscaping grants program. During
the pilot program, 5.5 acres of impervious area was treated over a 3 year period when MSD
funded 100% of the cost of the Green Infrastructure. This equates to approximately 80,000 sq.
ft. impervious area (or 30 ERU) per year total, with a creditable amount of 15 ERUs for a total
credit of $405 per year.
All Customers
(1) MSD would bill based on impervious area. Stormwater BMPs that are designed to be
pervious would be 100% excluded from the billable area because they are pervious, not
impervious. Examples include green roofs and pervious pavement. If aerial photography
identifies these areas as impervious, the customer would need to apply for this 100%
billing adjustment. A minimum of 1 ERU must be removed for commercial customers.
For credit forecasting purposes, MSD considered credits from the previous impervious
rate from 2008 to 2010, which resulted in 255,700 sq. ft. or 98 ERU, 30 ERUs added per
year resulting in a billing correction of $810 per year.
(2) A 70% credit would be available to those customers whose stormwater drains directly to
a large river (Missouri, Mississippi, or Meramec) or other equivalent situations. Thirty
percent (30%) of the total impervious area over the entire District equates to areas within
public right-of-way, therefore, 30% of billable area would be chargeable to all customers
in the District. Therefore, the credit would apply to the balance of the bill, or a 70%
credit, to represent the private component of impervious area, which for these customers,
would not cause runoff to flow through any public storm system or natural drainage
system within the District boundary.
For credit forecasting purposes, MSD considered credits on all customers’ parcels that
are directly tributary to the major rivers, which represents 627 customer parcels with 22
million sq. ft. or 8,545 ERUs resulting in a credit of 5,981 ERUs, or $161,000 of potential
revenue that would not be billed.
(3) A 35% billing credit will be given to customers for whom the impervious surface area is
less than 15% of the gross surface area for a parcel or contiguous parcels, equivalent to
Environmentally Sensitive Development. The minimum lot size would be 3 acres. For
these customers, no impervious surfaces would be actively treated, however, this credit
considers the runoff from these customers will have about half of the impact of normal

development. Since 70% of total impervious area, and therefore the bill, is from private
sources, the credit would equate to half of this amount, or 35%.
For credit forecasting purposes, a total of 2,981 customer parcels have less than 15%
impervious surface on lots larger than 3 acres, and which do not otherwise drain directly
to a major river. Total impervious area for these customers equals 81 million sq. ft. or
31,476 ERUs, resulting in credits of 11,016 ERUs, or $297,000 of potential revenue that
would not be billed.
Note – Stormwater BMP credits will only apply to new facilities. Customers can only qualify
for one of the aforementioned credits/incentives. Where the Environmentally Sensitive
Development parcels drain to a large river, the Major River credit was applied first. Otherwise,
the credits were calculated independently.
