Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
1. INTRODUCTION
The Town of Morrisville (Town) hired Freese and Nichols, Inc. (FNI) in June 2019 to review, evaluate and
update the Town's five-year strategy for its stormwater management program, and evaluate
considerations for an adjusted stormwater utility fee structure to enhance equitability. Multiple meetings
and comprehensive interviews were held with appropriate Town staff to gain a full understanding of the
Town's needs, cost, revenue and level of service associated with its stormwater program. Cost projections
were compiled from a variety of sources to compare against the current stormwater utility fee and assess
any gaps in the existing fee structure. FNI assessed the Town's stormwater program, identifying
opportunities to increase operational efficiency and cost effectiveness by assessing the Town's
stormwater infrastructure inventory, reviewing regulatory compliance documents, identifying and
examining gaps or deficiencies in processes such as development reviews and storm system operations
and maintenance, and reviewing the Town's capital improvement project (CIP) ranking and
implementation process. The CIP budgeting process and schedule were assessed to identify
recommended strategies for implementation. The following report includes our findings and prioritized
recommendations for the Town to successfully enhance and implement a five-year stormwater
management program strategy.
1.1. Description of the Town of Morrisville
The Town of Morrisville is located in North Carolina. It is primarily in Wake County with a very small
portion extending north into Durham County. The Town of Chapel Hill and City of Durham are located to
the northwest, Jordan lake is to the southwest, the Town of Apex is to the south, the Town of Cary and
City of Raleigh are to the southeast, and Raleigh -Durham International Airport is to the northeast.
Morrisville is part of the booming Research Triangle metropolitan region, which includes Raleigh, Durham,
and Cary. It encompasses approximately 9.9 square miles in jurisdictional area as shown in Figure 1-Town
of Morrisville Study Area Map and cannot annex additional land.

5tormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
In the 2010 census conducted by the U.S. Census Bureau the population estimate for Morrisville was
18,576. This was approximately a 257% growth rate from the 2000 census population estimate of 5,208.
In the 2015 Town of Morrisville Special Census, population was estimated at 23,699. As of 2018, the U-S.
Census Bureau estimates the population to be 27,453. It is estimated that the population will approach
approximately 30,000 at the next Census. The Town estimates it is currently at least 80% to full build -out.
An estimated 6,078 residential properties and 489 non-residential properties are located within the
Town's limits. The non-residential properties encompass about 70% of the impervious area in parcels
(excluding roads) within the Town. Figure 2 - Impervious Area by Property Type shows the breakdown of
impervious area by the Town's current stormwater utility categories.

1.7. Legal Basis and Limitations of a Stormwater Utility
The State of North Carolina provides municipalities the opportunity to establish a stormwater utility,
which is a legal mechanism used to generate revenue to finance the Town's cost to provide and manage
6

stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
stormwater services in the Town. To provide these services, municipalities are authorized by North
Carolina law §160A-314 to establish "schedules of rents, rates, fees, charges, and penalties for the use of
or the services furnished by any public enterprise". In accordance with State law, these schedules for:
"providing stormwater management programs and structural and natural
stormwater and drainage system service may vary according to whether
the property served is residential, commercial, or industrial property, the
property's use, the size of the property, the area of impervious surfaces
on the property, the quantity and quality of the runoff from the property,
the characteristics of the watershed into which stormwater from the
property drains, and other factors that affect the stormwater drainage
system".
The stormwater utility fee is a service fee and must be based on the projected cost of providing
stormwater service within the Town's jurisdiction. Based on North Carolina law §160A-314:
"Rates, fees, and charges imposed under this subsection may not exceed
the city's cost of providing a stormwater management program and a
structural and natural stormwater and drainage system. The city's cost of
providing a stormwater management program and a structural and
natural stormwater and drainage system includes any costs necessary to
assure that all aspects of stormwater quality and quantity are managed
in accordance with federal and State laws, regulations, and rules".
Some stormwater-related costs that are allowed by State law to be included in the development of
the projected revenue needs for stormwater service typically include the following:
• Property acquisition
• Service fees (architectural, engineering, legal, surveys, etc.)
• Capital (equipment, machinery, furniture, facilities, etc.)
• Funding and finance costs for construction projects
• Debt service
Administration

The stormwater utility service area consists of land areas that contribute overland flow into the
watersheds in the municipality. The service area cannot extend farther than the Town limits.
1.3. Stormwater Utility Policy
This stormwater utility report provides an overview of an assessment of the feasibility for the Town
of Morrisville to finance its stormwater-related activities solely through revenues from a stormwater
utility fee. Under the present system, necessary Stormwater-related activities are either financed through
the General Fund, current Stormwater Fund, or are unfunded. Most storm system development and
installations have occurred within the last 15 years, and as a result little preventative maintenance has
been conducted to date. Maintenance that does occur tends to be reactive in nature in response to
episodic issues and community complaints, No current budget is allocated to assess the stormwater
system condition or conduct preventative maintenance. Preventative maintenance and condition
assessments help maintain the stormwater flow capacity needed to minimize flooding hazards and
maximize the useful life of installed infrastructure, delaying costly rehabilitation and replacement
activities. Significant capital and management improvements to the overall stormwater system have been
previously identified as necessary to protect existing development and to meet ongoing regulatory
requirements.
The Town is one of many municipalities subject to federal stormwater quality regulations that require
the Town to further protect and enhance water quality in creeks and lakes through the development of a
stormwater quality management program. As an operator of a municipal separate storm sewer system
(MS4) as defined by the U.S. Environmental Protection Agency, the Town is required to develop a multi-
faceted program to protect stormwater quality before it enters creeks, rivers, and lakes. The program
includes measures to protect stormwater quality, such as the following:
• Storm system maintenance
• Structural and non-structural water quality protection measures
• Storm system mapping and inspections
• Public education, outreach and involvement
• City ordinances regulating construction activity, illicit discharges, and post -construction runoff
• City staff training and operations improvements

The purpose of this study is to evaluate the current stormwater utility program and fee and include
considerations for a modified fee structure to enhance equitability and to finance each of the identified
storm system activities and improvements, including associated administration, service, equipment and
other stormwater-related costs. The study strives to identify an appropriate fee based on the projected
cost of providing stormwater services in the Town.
The following general goals and policies were identified in consultation with Town staff for the
stormwater utility study. These goals provided an initial basis for the potential purposes and benefits of
the utility for the Town of Morrisville.
• Evaluate a model for a self-sustaining stormwater utility to serve as the stable source of new
stormwater-related funding, requiring no transfer from the General Fund.
• Finance all of the following specific stormwater-related activities:
Ongoing implementation and maintenance of the Town's Phase II MS4 stormwater
management program to comply with U.S. Environmental Protection Agency (EPA) and
North Carolina Department of Environmental Quality (NCDEQ) regulations and permits,
as applicable.
Encourage proactive/preventative maintenance for existing storm system infrastructure.
ct Maintenance, compliance, engineering, and/or administration activities
o Equipment for drainage maintenance
o Prioritization and implementation of capital improvements to the stormwater system
infrastructure
Update to GIS inventory and stormwater database
o Perform condition assessments on all existing and critical infrastructure
Stormwater ordinances and design criteria modifications
c1 Engineering studies and design
• Validate the Town's existing stormwater utility fee and fee structure through level of service, cost,
and revenue evaluation relating to its stormwater program.
• Maintain a fair and equitable method to assess fees for existing and developed properties'
impacts to the Town's stormwater system.

2. COST OF STORMWATER SERVICES
Town of Morrisville
The stormwater utility fee is a common legal method to address a significant portion of the financial
burden for stormwater management. This section includes considerations and options for services the
Town may finance with stormwater utility revenues. A variety of options for staffing, equipment, and
services to provide are made available for reference. The Town may choose to select from the provided
list or additional options as long as the options are stormwater-related. Default values for several
parameters are provided in this report with input from Town staff. This includes estimated rates for labor,
equipment purchase, Town growth, and inflation.
2.1. Annual Expenses
FNI analyzed and compiled stormwater budget and expense data provided by the Town. Annual
expenses from FY 2014 thru FY 2019 are reflected in Table 1- Annual Stormwater Expenses (2014-2019).
Table 1- Annual Stormwater Expenses (2014-2019)

The stormwater program currently funds all three staff positions (stormwater manager, stormwater
engineer, and environmental specialist), a pickup truck, and a street sweeping contract (approximately
$32,000). Through interviews with Town staff it was determined that personnel are challenged in fully
conducting required responsibilities due to capacity limitations. The environmental specialist is at or past
productive capacity, with current responsibilities including but not limited to:
(-50%) Structural control measure (SCM) inspections and enforcement of 5CM maintenance
for private SCMs.
• (-25%) Public outreach/participation
10

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
• (-25%) Remaining time is dedicated to:
c. stream determinations with stormwater engineer
o drainage complaints support
o response to illicit discharge complaints
o dry weather monitoring
o outfall inspections that just started this year for the first time and will be carried out
once a permit cycle (once every 5 years)
The stormwater engineer's current main responsibilities include:
• (-10%) Responding to drainage complaints
• ("5%) Stream determinations
• (-70%) Development reviews
• (-10%) Initial construction site inspections and SCM as -built reviews
(-5%) GIS and project management
The stormwater engineer currently has capacity to make it to only the major SCM construction sites.
Additional staff resources or an adjustment in engineer responsibilities would be necessary for the
stormwater engineer to inspect construction of all SCMs. Similarly, inspection of existing SCMs for proper
operation and maintenance is lacking due to insufficient staff capacity.
2.2. Cost of Service Development Considerations
Options were evaluated to determine an appropriate methodology for identifying the projected cost
of providing stormwater service in the Town. It was determined that the following considerations would
be incorporated into the assessment of the cost of stormwater services for the purpose of determining
the revenues necessary for the stormwater utility:
• Identify expected stormwater• related costs.
• Evaluate a five-year period for projecting cost of service needs. Cost projections beyond five years
are inherently less reliable and may not provide the Town with quality information desired for
planning purposes.

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc.
Town of Morrisville
• Establish and maintain a minimum of a 90-day operating balance in the stormwater utility fund
to account for contingencies.
• Consider prorated costs for items not solely associated with stormwater but that have an
application for stormwater management. Examples include engineering staff, maintenance crews,
and maintenance equipment.
• Plan for stormwater utility revenues to finance all direct operating costs and administrative costs
for stormwater-related activities, including major capital projects.
• Address as much of the Town's stormwater-related costs as practicable through the stormwater
utility fund.
2.3. Cost of Service Assumptions
For the purposes of the five-year plan, an anticipated annual cost increase of two percent (2%) per
year was incorporated into the planning process. The expense rate inflation is assumed to remain constant
over the five-year projection period.
2.4, Infrastructure Inventory Assessment
The Town provided FNI with information related to the management of its storm water system
infrastructure. The Town has a Geographical Information System (GIS) containing a large amount of data
related to the storm water system, including, but not limited to: asset condition assessment outfalls, curb
inlets, curb cuts, yard inlet, other, drainage net junctions, combo inlets, spillways, unverified structures,
grate inlets, BMPs, manholes, pipe inlets and outfalls, culvert points, culverts, pipe barrels, pipes, culvert
barrels, channels, master link, major basins, water bodies, sub basins, Town roads, two -foot and ten -foot
Lidar contours, streams, stream buffers, County mask, ED limits, and Town limits. This information was
also provided in text and XML formats. Zoning information was also provided as part of the Town's GIS
data. From interviews with Town staff, the GIS inventory needs to be updated to capture the last two
years of development, which would primarily include digitizing as-builts.
The Town also provided a Microsoft Access database designed, initially populated, and provided by
FNI as part of a prior project to record and track public stormwater complaints and track CIPs. These
projects are mostly complaint -based, and Public Works performs some of the minor activities as described
in detail in Section 2.7 Storm System Operations and Maintenance. This database is linked to the Town's
12

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
website where these concerns can be submitted electronically. It is recommended that the Town update
the stormwater database with projects identified since the database's inception.
Multiple forms of data relating to condition assessments were provided such as outfall condition
assessments as an AutoCAD shape source file and a Microsoft Excel spreadsheet showing the Town's
stream conditions. A watershed study map was provided in PDF and GIS format. Standard operating
procedures were also provided for the stormwater program.
The Wake County (West) Multi -Jurisdictional HMP includes an asset inventory and is intended to
include a critical facilities map for each participating jurisdiction, including Morrisville. This inventory and
map of critical facilities would be very helpful to the Town to help identify and prioritize needs to protect
each of these specific locations. Although most of Morrisville's development has occurred in the last 15
years, several older areas may need review. The Town has interest in focusing on condition assessments
to identify and prioritize critical infrastructure over a rotating five-year period throughout the Town.
2.5. Review of Town's Regulatory Compliance
A. Phase Il MS4 Stormwater Quality and Buffer Permit Programs
Phase II of the National Pollutant Discharge Elimination System (NPDES) Storm Water program was
signed into law in December 1999, which requires small cities like the Town of Morrisville to develop,
implement, and enforce a storm water program designed to reduce the discharge of pollutants from the
Municipal Separate Storm Sewer System (MS4) to the maximum extent practicable. The Town received
their initial Phase II M54 permit from the North Carolina Department of Environmental Quality (NCDEQ)
in November 2005. The Town submits a report on the status of their stormwater management program
every year as a condition of the Phase II permit, which they renew every five years. The Town's current
Phase II MS4 permit expires in 2022, but an NCDEQ audit is expected to occur sometime in 2020.
Per the Town's Comprehensive Stormwater Management Plan (last revised December 13, 2017), the
Unified Development Ordinance (UDO, effective July 1, 2014, updated July 23, 2017) and the Engineering
Design & Construction Manual (EDCM, effective July 1, 2014, updated September 1, 2016) are the two
documents detailing how the Town will enforce and regulate stormwater issues within its jurisdiction.
They supersede the previous Stormwater Management Ordinance (adopted February 28, 2012) and the
Design and Construction Ordinance. The most recent plan update is from 2017. It includes an
organizational chart and shows that the Town's Stormwater Engineering Manager position serves as the
Stormwater Program Manager as well as the Stormwater Division Supervisor. One of the Town's primary
I3

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
goals outlined in this 2017 stormwater management plan is to assign responsibility to private owners and
public agencies alike and hold all parties, including itself, accountable for pollutants that enter the M54
and for the water quality of its receiving streams.
The target pollutants and/or stressors of concern in the receiving waters of the Town's MS4 are
sediment and other suspended solids, excess nutrients such as nitrogen and phosphorus, and litter and
yard waste. As part of their public education and outreach goals, the groups they should be targeting with
applicable information to reduce the target pollutants and/or stressors are homeowners, landscaping
companies, contractors and developers, restaurants, industrial groups, and special interest groups such
as HOAs, churches, boy/girl scout troops, etc.
Jordan Lake Buffer Rules and Neuse River Rules are currently suspended as of October 2019; however,
they are expected to take effect in the near future. The rules would require nutrient targets for new
development but would not require upgrades to existing SCMs. Jordan Lake Buffer Rules would apply in
the Northwest Morrisville area; therefore, the Town has incorporated the Jordan Lake Water Supply
Nutrient Strategy Rules into their Stormwater Program. The Town of Morrisville has multiple
requirements to meet under the Jordan Lake Nutrient Management Strategy (Existing Development Stage
One Adaptive Management Program). Certain measures are already required by the NPDES Phase it MS4
stormwater permits (Public Education Program, Illicit Discharge Detection & Elimination Program, and
Best Management Practices Maintenance Program), which means the Town is only required by the Jordan
Lake Stage One Adaptive Management Program to identify retrofit opportunities and other load -reducing
measures from existing development. The Town's population within the watershed is less than 15,000
residents, requiring the Town to have at least one retrofit project opportunity identified every three years -
Although funding processes and construction of these identified retrofit opportunities are not required
for several years, the Town has proactively identified and constructed two retrofit opportunities in the
last five years. The most recent retrofit the Town reported was constructed in 2017 with an estimated
cost of $2,000. It is currently being monitored by North Carolina State University Department of Biological
and Agricultural Engineering. The next potential retrofit project is scheduled to be identified by the Town
in the 2020 annual report.
From a review of the Town's 2018 NPDES Phase II M54 assessment, the following items need to be
reviewed, updated or maintained:
• Review and maintain the interlocal agreement outlining the relationship between the Town and
Wake County for the purposes of the Construction Site Runoff Control Program
14

B. Hazard Mitigation Action Pion (HMAP)
The Hazard Mitigation Action Plan is a preventative and proactive plan that communities develop to
minimize potential impacts from natural hazards before they occur, such as flooding and erosion from
hurricanes. The federal Disaster Mitigation Act (DMA) of 2000 requires that state and local governments
develop hazard mitigation plans as a condition for federal grant assistance, which includes a mandatory
16

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc Town of Morrisville
five-year update. Almost all grant programs that use Federal Emergency Management Agency (FEMA)
funding for storm water related projects require that the applicant have a FEMA-approved hazard
mitigation action plan (also called a local mitigation plan).
The Town of Morrisville currently has a FEMA-approved hazard mitigation action plan, which is rolled
up as part of the wake County Multi -Jurisdictional Hazard Mitigation Plan (HMP). This HMP was developed
under the guidance of a Hazard Mitigation Planning Committee (HMPC), which included representatives
of Town departments, federal and state agencies, citizens and other stakeholders. The Town of Morrisville
had two representatives from the Planning Department and one Citizen Stakeholder representative. On
January 29th, 2015 the Wake County Multi -Jurisdictional HMP was approved by FEMA and on May 26th,
2015 the Morrisville Town Council officially adopted it. The town continues to provide an annual report
to the Planning & Zoning Board, the Town Council, and the citizens of Morrisville on efforts to address the
hazard mitigation action plan items. The 2018 Annual Hazard Mitigation Plan Report is the latest update.
The current plan approval period is five years, which means expiration will occur in January of 2020.
The Wake County HMP Complete Draft is available as of the date of this report, and Table 2.8 (Status of
Previous Mitigation Actions) states that the Town of Morrisville completed six mitigation actions, deleted
zero, and carried forward three.
In order to update this multi -jurisdictional mitigation plan, the Town has reconvened with the HMPC.
The Town is a part of the Wake West region, which includes the following communities: Apex, Cary,
Fuquay-Varina, Garner, Holly Springs, Morrisville, Raleigh and Wake County. The North Carolina
Emergency Management (NCEM) Risk Mitigation Planning Branch works with local government on the
process and timeline for updating/reviewing its local mitigation plan. NCEM uses a database to track the
status of all hazard mitigation plans in the state down to the municipal level. NCEM encourages local
governments to begin applying for funding to update their plan in years two and three of their approval
status because of the unpredictability of when funds will become available. The timeline that the Town
follows to update its hazard mitigation plan is generally 30 months from the time the funding application
is submitted to NCEM/FEMA approval, and it includes:
• Apply for plan update funding in years two and three.
• Six to eight months from close of the application period to receive funding award letters from
FEMA.
17

5tormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
• Approximately three to four months for the local procurement process to hire a contractor to
assist in the update.
• Twelve months to update the plan through the planning process.
• Six months for NCEM and FEMA to review.
FNI recommends that the Town continue its involvement in the development and update of the Wake
Multi -Jurisdictional HMP. It would be helpful to include a storm water representative from the Town to
advocate for projects and action items related to its storm water program.
C. NPDES/DEQ Construction Site Erosion Control Activities
The Town relies on the Wake County Sediment and Erosion Control program to provide the Town with
services to comply with NPDES Phase II MS4 permit requirements and implementation of the Town's
Construction Site Runoff Controls program. The Town adopted Wake County's Sediment and Erosion
Ordinance under an established interlocal agreement. As far as responsibilities, Wake County is
responsible for ongoing construction site inspections after the initial one conducted by the Town to ensure
compliance at each site. The Town is also responsible for monitoring effectiveness of the Wake County
program within the permittee jurisdiction. If a permit exists, sediment and erosion control problems at
construction sites are reported to Wake County. Any potential sediment and erosion control violations
are reported to the Town via phone hotline or through the online reporting system or reported directly
to Wake County Erosion Control staff. Wake County collects erosion and control fees directly.
Although this contract was recently renewed with the County, which includes a 180-day termination
clause, the Town is interested in exploring the option to bring erosion and sediment control in-house. For
this to occur, the Town would need to add one staff position and an additional vehicle for site visits. An
entry-level engineer is recommended for the position to provide support to the stormwater engineer for
development reviews, as capacity permits. Staffing internally for erosion and sediment control would
provide tighter control on the quality of service provided. In addition, combining this part-time staffing
need with several other part-time staffing needs that already exist could collectively cover a full-time
position, allowing for a potentially cost-effective staffing approach to address multiple needs.
Alternatively, outsourcing erosion and sediment control services allows for more financial flexibility and
relieves the Town from a long-term financial burden associated with the need for staffing, re -staffing,
training, maintaining technical efficiency, and related staffing management needs.

D. NF1P FEMA Floodplain Management
Town of Morrisville
The Town of Morrisville is a participating community in FEMA's National Flood Insurance Program
(NFIP), which is administered through the North Carolina Floodplain Mapping Program (NCFMP). The
partnership between FEMA, NCFMP and participating communities includes flood hazard maps, flood
insurance and regulations. North Carolina is unique in the sense that the State, rather than the Federal
government, created and maintains the Flood Insurance Study for all North Carolina communities. The
NCFMP was established in 2000, through a partnership with FEMA, with a mandate to update flood hazard
data for all 100 counties.
The Town of Morrisville is located in Wake County, which recently went through the process of
updating the Flood Insurance Rate Maps (FIRMS). FEMA is required to assess the need to revise and
update all Floodplain areas and flood hazard zones at least once every five years. The last Wake County
update occurred in 2006, and preliminary FIRMs were recently published by the NCFMP in April of 2015.
In the Summer of 2018, the Town's UDO Section 5.6 Floodplain Management was updated and FIRMs
became effective.
FNI recommends the Town work closely with the NCFMP to ensure major flooding issues and locations
are taken into consideration when flood maps are updated. Quarterly or semi-annual meetings should be
scheduled to ensure the community is represented well.
2.6. Development Reviews and Requirements
The Morrisville Unified Development Ordinance (UDO), Article 2 provides the framework and
requirements for the Town's development review process. Depending on the application, there are
various steps outlined in the Town's UDO such as application submittal, staff review and action, scheduling
and public notice of meetings, and more. Energov is the Town's development tracking software program
and can be a resource for identifying and integrating new development and redevelopment into the
stormwater utility fee program. Also, Town Council is authorized to establish, amend and update
application fees, which vary based on the type of application. Development application and permit fees
account for approximately 6% of the stormwater fund budget each year on average.
Stormwater staff involvement does not seem to be necessary in the application submittal or for
scheduling and notice of public meetings. The steps within the process that require some degree of
stormwater staff involvement include the staff review phase, assisting the Town Engineer with providing
any required recommendations, and attending any hearings required for riparian buffer and stormwater

variances. Throughout the development review process, the Town Engineer serves as the liaison between
the applicant and appropriate Town staff. The addition of an entry level engineer previously mentioned
would support development reviews -

2.7. Storm System Operations and Maintenance
The Town's storm system operations and maintenance consists of insourced and outsourced regularly
scheduled maintenance activities for associated infrastructure, equipment, and facilities. Given the
Town's current and build -out size, it will likely continue to be cost-effective to use hybrid solutions
regarding what is insourced and outsourced. This section focuses on a process for setting up a formal
stormwater system maintenance program, including identifying the Town's infrastructure, the most

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc.
Town of Morrisville
critical infrastructure, and cost-effective approaches to conduct inspection, monitoring, maintenance,
rehabilitation, repair and replacement activities. The Town has recognized the need to first identify what
needs to be done to maintain the stormwater program and meet the community's expected level of
service, and then develop the associated costs.
Although some regularly scheduled maintenance activities occur, the Town operates mostly in a
reactive manner, which includes reactive maintenance activities that result from drainage complaints
received via the Town's website. These drainage complaints are compiled in a Microsoft Access database.
Currently, the Town's Public Works department has crews that perform limited stormwater
operations and maintenance activities like outfall rock armoring, non -stream riprap work, and minor
flushing out of pipes and culverts, but the majority of the work is outsourced. Currently the labor cost of
the Public Works crews are not funded by the stormwater program, but materials and related expenses
are paid by the stormwater fund.
Outfall inspections just started this year (2019) for the first time. The Town expects these inspections
to occur once a permit cycle, or once every five years.
The Town actively contracts out for maintenance work, as needed, in a reactive manner. Public Works
does not do significant maintenance activities such as pipe repair/replacement, culverts, rock armoring
for streambanks, significant sediment removal, vacuum inlets, stream restoration work, streambed work,
or street sweeping, as these activities are contracted out. The contract for street sweeping is paid for by
stormwater utility funds, with a new contract recently issued for an annual cost of $32,000. This contract
covers Town -maintained roads, parking lots and North Carolina Department of Transportation (NCDOT)
roads. Private roads are not covered. Street sweeping occurs six times per year. The Town does not have
a vacuum truck or jetter available for storm system maintenance and may possibly benefit from renting
this type of equipment.
A list of common crew positions, including salary and compensation with benefits for FY 2020 is
provided in Table 4 - Potential Stormwater Maintenance Grew Positions. Rates for all positions currently
assume 100 percent financing by the stormwater utility. Positions not fully dedicated to stormwater-
related services can be funded on a pro -rated basis as long as stormwater utility funding is limited to
stormwater-related services. The maintenance crew would assume responsibility for routine storm sewer
system maintenance activities such as stormwater ditch cleanouts, inlet cleanouts, and drainage swale
landscaping. In addition, the drainage crew would complete larger maintenance activities and potentially
21

Starmwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc. Town of Morrisville
some small capital projects within the crew's capabilities. These projects could include activities such as
the installation of erosion control measures and driveway culverts in grass -lined roadside ditches.
The projected cost to purchase equipment for the storm system maintenance crew is provided in
Section in Table 5 - Cost to Purchase Equipment.
The purchase price of the equipment is depreciated over its expected service life to provide an
annualized cost. Annual O&M costs include projected fuel and routine maintenance costs.

Stormwater BMPs are also maintained by an outside company that performs monthly maintenance
and monitoring of the Town's stormwater BMPs. As part of the NPDES Phase II M54 program, the Town
requires annual operation and maintenance (0&M) reports for each BMP and is implementing long term
0&M by legal documentation and maintenance security funds. Normal maintenance includes mowing and
vegetation maintenance, removal of trash/debris, removal of woody vegetation, checking/cleaning rip rap
dissipators, checking/clearing draw -down device, checking slopes for erosion, noting grass bare
spots/damage, removal of invasive vegetation in pool, removal of sediment, clearing trash rack, removal
of sediment from inlet area, testing emergency draw -down, noting pool level, mowing banks, noting and
treating primrose/algae present, and blowing leaves from the system (seasonal). This contract is ongoing
and was dated August 2, 2019 with a Not to Exceed (NTE) amount of $10,890.00. See Table 6 - FY 2019

Stormwater Program Evaluation and Funding Report

FNI recommends the Town update existing Stormwater Standard Operating Procedures (SWSOPs) and
create new ones for all maintenance activities, in-house and outsourced. Suggested 5WSOPs that were
not identified in the data received from the Town include street sweeping and other maintenance
activities on stormwater infrastructure. SWSOPs should be reviewed on an annual basis and updated, as
necessary throughout the year to ensure efficiency, consistency, and quality in the Town's Stormwater
Program. It appears that most existing SWSOPs have not been updated in the last five years.
In addition, a critical infrastructure and facilities map should be created, and condition assessments
in the older Morrisville areas should be performed. FNI recommends the Town obtain infrastructure
inventory and condition assessment of roadside ditches as these have significant impact on the whole
stormwater system.
2.8. Capital Improvement Project Ranking and Implementation
The Town provided FNI with its Stormwater Database Microsoft Access file. This database is mostly
complaint -based and appears to have last been updated in 2016. Public Works has the capability to
complete minor projects that fall within their capabilities as mentioned in Section 0. This database
compiles information for all capital improvement projects and associated ranking and implementation
status. The Town currently has one -page reports available for forty-six CIPs, with a variety of statuses
associated. Project status can be'M•monitor','C-Closed','IP-In progress','B-Ready to Bid','SC-Scheduled',
or no status at all. Thirty-one projects are currently included in the ranking system. See Table 7 - CIP
Ranking and Status for a list of all projects in the Town's database and associated status. It is important
to note that most of these projects have not been planned or budgeted for in the General Fund. Current
stormwater projects that are planned or budgeted for in the General Fund include:
• stormwater wetland construction project across the street from the municipal complex:
$1,200,000 budgeted, and $1,300,000 engineer's construction estimate
• two culvert projects planned for Fairview Drive and Green Drive: $400,000 budgeted, and
$722,000 engineer's construction estimate.
The Town will continue to see a steady maintenance backlog especially once these one-time projects
are completed. Although a watershed study has been completed in the last five years, a closed system
study has not been conducted. There is no current budget to perform stormwater system condition
assessments. The Town purchased a pipe inspection robot last year for older infrastructure and main
culverts. Currently no maps exist showing older or critical infrastructure locations. The Town would like
25

Town of Morrisville
to update its GIS inventory, preferably in the beginning of 2020, to capture the last two years of
development. This work would primarily include digitizing as-builts. The Town also does not currently have
inventory of roadside ditches

2.9. Stormwater Cost Share and Fee Credit Program
The stormwater utility fee is required to be based on the Town's cost of providing drainage service,
which was evaluated and compiled from a variety of sources.
The Town of Morrisville has a policy that prohibits the use of public money for private property
without public benefit. Public easements are utilized to mitigate or fix any issues that arise. The Town is
interested in implementing a cost -share program for water quality improvements on private property,
similar to the City of Raleigh's current approach. This program establishes opportunities for customers to
receive credits and adjustments to their stormwater utility fee. Credits are associated with, but not limited
to, the construction, operation, and maintenance of privately owned stormwater facilities that benefit
the Town beyond the Town code -required standards (UDO Section 7.4.2). Customers may qualify for a
credit when they can demonstrate that their existing or new stormwater facility provides cost saving the
Town would otherwise incur as part of its stormwater management efforts. For example, at the City of
Raleigh, developers are currently required to control for the 2-year and 10-year design storms onsite;
however, if 25-year or larger storm events also are controlled, a 20% fee credit is applied.
27

Stormwater Program Evaluation and Funding Report

3. FEE STRUCTURE EVALUATION
3.1. Current Fee Basis
Town of Morrisville
By law, the stormwater utility fee rate must be set according to a basis that is directly related to
stormwater. As a result, fee rates cannot be based solely on certain readily accessible information, such
as property values or water usage rates. Based on interviews with Town staff, it is understood that the
Town's current stormwater utility rates are based on the amount of impervious area for each property,
although the impervious area for each property was not a part of the Town's data made available for
review, so confirmation of this was not possible. Impervious surfaces do not provide stormwater
significant opportunity for infiltration into the soil and result in increased stormwater runoff to the
municipal storm sewer system.
Property improvements that typically are considered as impervious areas include buildings, paved
parking lots, driveways, patios, and walkways. Gravel parking lots and driveways are also considered
impervious area because of the low infiltration rate of stormwater through their surface. Sidewalks within
the Town easement typically are not included in individual property impervious area calculations.
The potential stormwater impacts of impervious area to the storm system include the following:
• Increased total volume of water required to be managed by the municipal storm system resulting
in flooding
• Increased peak flows from storm events resulting in flooding
• Increased flow velocities resulting in increased erosive actions in creek channels and adjacent
properties
• Increased pollutant loading resulting in degraded water quality
Site -specific design and maintenance approaches may minimize one or more of these impacts. The
Town may determine to reduce the stormwater utility fee for a property by an equitable amount to
account for the beneficial stormwater impact of design and/or maintenance approaches by a property
owner.
Currently, the Town of Morrisville's existing stormwater utility fee structure is based on an annual
cost per equivalent residential unit (ERU). An ERU in the Town is defined as 2,800 square feet impervious
area. The Town has six stormwater utility groups as shown in Table 9 - FY 2020 Stormwater Utility Fee
Estimates and Figure 3 - Current Stormwater Utility Property Billing Classifications. Each single-family
28

Stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc.
Town of Morrisville
residential property is assessed a fee of 1 ERU per year. Each townhome is assessed one-half ERU per year.
Undeveloped property is not assessed a fee. All other property is assessed a fee based on the number of
ERUs of impervious area on the property. The current fee per ERU is $25 per year.

3.2. Fee Structure Evaluation
Developed properties with impervious area increase the rate and/or volume of stormwater runoff to
the municipal storm system. Infrastructure improvements, ongoing maintenance, inspections, and
evaluations are necessary to properly manage the increase in stormwater discharge from impervious area.
Impervious area includes rooftops, paved parking lots, paved driveways, gravel driveways, walkways, out
buildings, and patios. It does not include vegetated areas or swimming pools.
FNI conducted an analysis and evaluation of the Town's existing fee structure to identify revenue gaps,
if any, and to consider basic fee structure options. Raster analysis of current aerial photography of the
Town was conducted to estimate impervious area for residential properties throughout town, and manual
digitization was conducted for non -single family residential properties, including commercial, industrial,
multifamily, Town, schools, and other developed properties. For ease of reference, non -single family
residential properties are referred to as commercial properties through the remainder of this report. An
example of the impervious area determination for a non-residential property is shown in Figure 4 -
Example of Impervious Area for Non -Residential Property.
29

5tormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc.
Figure 4 - Example of Impervious Area for Non -Residential Property
Town of Morrisville
Properties with less than 400 square feet of impervious area were considered to be undeveloped, and
no stormwater utility fee was assigned to those properties. Residential properties with at least 400 square
feet of impervious area were assigned an ERU value of 1, and townhomes were assigned a value of 0.5
ERU. Commercial properties were assigned ERU values in whole ERU increments, rounded up to the
nearest ERU. For example, a commercial property with impervious area between 400 and 2800 square
feet would be assigned 1 ERU, while a commercial property with between 2801 and 5600 square feet of
impervious area would be assigned 2 ERUs. Use of whole ERU increments simplifies Town staff billing
administration while maintaining an equitable approach for rate payers.
The resulting impervious area measurements were used to calculate the total amount of equivalent

Table 10 - FNI-Calculated ERUs by Billing Classification shows the Town -wide projected ERUs based on
Town parcel data adjacent to FNI's calculated ERUs based on current aerial photography and digitization
efforts. The Town provided FNI with tabular and GIS data, which had slight differences in the number of
parcels. FNI utilized the Town's GIS data for comparison purposes, but calculations are also shown for the
Town's tabular data. The Town's current fee structure has no classification for undeveloped property,
which would not be assessed a stormwater utility fee. FNI classified properties as Undeveloped if less than
400 square feet impervious area was measured. This resulted in reclassification of approximately 860
properties throughout Town. Table 11 - Reclassification Summary shows the number of properties in
each SWU class proposed to be reclassified as Undeveloped, and Figure 5 - Stormwater Utility Property
Types with Updated Undeveloped Properties highlights the proposed Undeveloped properties on a map.

Total ERUs for each Billing Classification Group for Town Budgeted Parcels in Table 10 are based on
documentation provided by the Town for revenue projections. As previously mentioned, the total number
of parcels in this source from the Town is approximately 400 more than the amount shown in the GIS
parcel records provided to FNI. The FNI Estimated ERUs measured through raster analysis and digitization
are approximately 2,000 ERUs more than the budgeted estimate from the Town and 2,300 ERUs more

than the GIS estimate. The resulting projected annual revenue from the FNI estimation effort shows an
additional $50,000 of annual stormwater utility revenue should be collected than is currently budgeted.

3.3. Impervious Area Fee Structure Options
While this study does not consider specific fee structure alternatives, the subsection describes several
options for future consideration. The Town's current fee structure assigns 1 ERU to each house (Single
Family Detached) and 0.5 ERU to each townhome (Single Family Attached). Commercial properties are
assessed a fee for each ERU of impervious area on the property. Many stormwater utilities provide for
varying fees depending on the amount of impervious area for each property, whether commercial or
residential. The following rate structure considerations are intended to allow for the collection of
necessary revenue, be reasonable and equitable, allow for relatively simple administration, and be based
on stormwater-related use of the storm system.
Tiered Residential Rate Structure
Tiered rates are the most common residential rate structure alternative to the flat rate currently in
place in Morrisville. Assessing a lower fee for smaller residential properties relative to larger properties is
recognized and typically well -received by the community as a reasonable and equitable approach. Fee
administration efforts are higher than a flat rate, as it is now necessary to assign each residential property
to the appropriate tier based on impervious area. In practice, the additional administration is nominal if
proper processes are established and implemented. With proper allocation of costs and rates assessed,
implementing residential tiers would improve equitability but remain revenue neutral.
For example, if a three -tiered residential fee structure were implemented, single family residences and
townhomes are treated equally, so that the properties, whether single family or townhome, are assigned
to their residential tier based on the amount of impervious area. The lowest tier has an established
equitable breakpoint for charges to be assessed at 0.5 ERU for the smallest properties, the middle tier is
assessed at 1 ERU, and the top tier would assess fees for the largest residential properties at a rate of 2
ERUs. Table 13 - Example 3-Tier Residential Fee Structure shows a breakdown of the number of
properties and the projected ERUs and revenue for each residential tier. Note that this approach provides
enhanced equitability for individual rate payers without a loss of revenue to the Town. Figure 6 - Example
3-Tier Residential Fee Structure Distribution shows the breakdown of residential fee classifications in the
example 3-tier fee structure.

Tiered Commercial Rate Structure
Tiered commercial rates are less common than residential tiers but are implemented in certain
instances. Tiered commercial rates are often easierfor rate payers to understand but also typically provide
less equitability than a per-ERU approach as is currently implemented in Morrisville. Tiered commercial
rates tend to benefit the largest properties the most, as the select few extremely large properties get
grouped in with significantly smaller properties for an averaged tiered rate well below what they would
normally pay.
Whole-ERU Incrementation for Commercial Properties
Many stormwater utilities use an ERU as the unit basis for impervious area instead of square feet. A
key reason for this is to minimize administrative burden for insignificant impacts of minor variations or
inaccuracies in impervious area determinations. If fractional ERUs are intended to be maintained for
commercial properties, it is recommended to consider setting a rate structure basis on square footage of
impervious area instead of ERUs. Entities that follow this approach tend to calculate based on increments
of 100 or 1,000 square feet of impervious area, again to minimize administrative burden for insignificant
inaccuracies in impervious area determinations.
Fee Caps
A fee structure with a hard cap is not recommended, as it is inherently inequitable to smaller rate
payers. In instances where fee caps have been requested or are being considered, it is recommended to
instead consider a tiered fee structure for more equitability.
Base Fee
Base fees are another fee structure consideration. This is a fixed fee per property that is independent
of the amount of impervious area on the property. An example purpose for the base fee would be to
offset administration and overhead costs, which generally are equivalent for each account regardless of
the size of the property or amount of impervious area.
37

stormwater Program Evaluation and Funding Report
Prepared by Freese and Nichols, Inc.
Town of Morrisville
Implementation of a base fee has the effect of shifting the cost burden toward residential properties,
because the number of residential properties greatly outweighs the number of commercial properties.
Fee Credits
Fee credits are increasingly popular features of stormwater utility fees, as they encourage property
owners to reduce their impact to the storm system by offsetting fees where incentives to do so are
implemented. Common fee credit allowances include on -site stormwater management features, such as
detention ponds or structural control measures, that minimize stormwater flows and/or improve
stormwater quality before discharging to the public system. Less common is to provide fee credits for
activities such as public education, such as by schools, or for cleanup commitments, such as participating
in an Adopt -a -Spot program. In practice fee credits are well -received by the community in concept but
are under -implemented. A simple application process for the rate payer, as well as a simple review and
approval process for the Town, are important considerations for a successful fee credit program. Because
of the nominal fee reduction available relative to the application and administrative effort, few entities
provide fee credit opportunities for residential properties. Most fee credit programs target commercial
rate payers, but successful instances of residential fee credit programs exist.
Enhanced Impervious Area Fee Basis
More utilities are shifting from fee credits to an enhanced fee basis calculation approach, which better
approximates actual storm system impact as part of the fundamental fee structure and does not require
the administration of a fee credit program. Examples of this include factoring not just absolute impervious
area for each property but also the percent impervious area for the property. This recognizes that 10,000
square feet of impervious surface on a 10,000 square foot lot in the center of town likely contributes more
runoff, likely of lower stormwater quality, to the storm system than 10,000 square feet of impervious area
on a two -acre lot that is otherwise vegetated. Runoff from impervious area on the latter property has the
opportunity to infiltrate on -site prior to discharge to the system, reducing volume and rate and improving
water quality of the stormwater. Enhanced approaches require additional parcel data and administration
but significantly improve equitability. These concepts tend to be most beneficial when stormwater utility
rates are high enough to attract significant community attention.

4. REVENUE ASSESSMENT
Currently, the stormwater utility fee is the main source contributing to the stormwater budget.
Additional revenue is generated from permit fees. From an interview with the Town in late October 2019,
out of the current $577,000 annual stormwater revenue, $35,000 of that is from development application
and permit fees, and the remainder is from the stormwater utility fee. For the purposes of this study,
variations in revenue sources other than the stormwater utility fee are not considered.
4.1. Annual Revenue
The Town provided data from 2014-2019 for projected annual revenue from the stormwater utility fee.
Table 14 - Historical Annual Revenue (Estimated) and Figure 7 - Historical Revenue and Expenses show
the annual estimated revenue based on the developed property inventory each year. Historical financial
records to confirm the actual revenue collected were not reviewed.

Town of Morrisville
The Town's planning department estimates a 2020 US Census population of approximately 29,000.
During conversations with Town staff, it was also estimated that the Town is about 83% toward full build -
out. Based on these estimates, full build -out population would be approximately 34,940. Utilizing these
assumptions as a basis for calculations, the population growth percentage from 2020 to full build -out is
expected to be approximately 20.5%. Applying this same percentage to revenue and utilizing the
estimated 2019 annual revenue ($559,958) to be conservative, projected annual stormwater utility
revenue at full build -out is approximately $675,000.
4.2. Menu of Unit Cost of Services (per ERU)
This section presents a menu of staffing and equipment options and associated costs that the Town
might consider including in its stormwater program that would be funded through the stormwater utility
fee. The projected annual cost per ERU is provided for each item, based on the Town's total number of
ERUs of 27,034.

5. RECOMMENDATIONS
FNI recommends the following items shown in Table 17 - Summary of Recommendations to the Town
of Morrisville regarding its five-year strategy for implementation and optimization of its stormwater
program. Following these recommendations, three stormwater service options are provided for
consideration, along with the associated costs and required fees.
Table 18 - Option A: Enhanced Services (No CIP) includes existing stormwater services costs based on
an average of the prior three years. Proposed allocation of additional projected revenues based on
property fee adjustments recommended in this report are provided, including the addition of an entry
level stormwater engineer to assist with stormwater structural control measure construction inspections,
maintenance inspections, Phase II MS4 compliance, and development reviews. Additional funds for
contract maintenance of the storm system is also proposed to allow for a basic preventative maintenance
program. Option A does not require a fee adjustment from the current $25 per ERU per year.
Table 19 - Option B: Enhanced Services and 20-Year CIP includes the same existing stormwater services
costs and the proposed addition of an entry level stormwater engineer as shown in Table 18 but also
allocates funds to the currently known CIP list identified in the Town's Stormwater CIP Database. Option
B described in Table 19 provides revenues to complete the known CIP within a 20-year period on a pay-
as-you-go basis with stormwater utility revenues. An escalation rate of 3% per year was utilized when
determining the average annual cost. An additional allocation toward storm system management, shown
as Contract Maintenance, is proposed to provide for a more robust proactive maintenance program,
minimizing future capital needs for the existing storm system. Option B would require an increase of $14
per ERU per year to a total stormwater utility fee of $39.
Table 20 - Option C: Enhanced Services and 10-Year CIP includes the same existing stormwater services
costs and the proposed addition of an entry level stormwater engineer as shown in Table 18 and Table 19
but allocates funds to the currently known CIP list identified in the Town's Stormwater CIP Database to
complete the known CIP within a 10-year period on a pay-as-you-go basis with stormwater utility
revenues. An escalation rate of 3% per year was utilized when determining the average annual cost. An
additional allocation toward storm system management, shown as Contract Maintenance, is proposed to
provide for a more robust proactive maintenance program, minimizing future capital needs for the
existing storm system, Option C would require an increase of $28 per ERU per year to a total stormwater
utility fee of $53.
