AGENDA ITEM:
Proposed Lake Asbury Master Planning Area(LAMPA)Trunk Main Capital Cost Recovery Policy
Date: December 16,2022
BACKGROUND:
Clay County continues to experience significant growth in the Lake Asbury area. The Florida Department
of Transportation(FDOT) is advancing construction of the First Coast Expressway(FCE). Clay County is
investing in roadway infrastructure in the area to connect with the FCE,most significantly in the east/west
connector named Cathedral Oak Parkway (COP) within the LAMPA. Staff anticipates growth of homes
and businesses along the COP corridor will occur rapidly due to access to the FCE. In response, staff
recommends consideration to pioneer potable water, wastewater, and reclaimed water trunk main
infrastructure in this initial corridor in advance of this development. To accomplish this objective in first
roadway corridors, staff proposes the attached LAMPA policy with the incorporated capital cost recovery
fees.
Pioneering trunk main infrastructure ahead of that growth will position CCUA to better serve development
and those future customers. CCUA will also realize a cost benefit if we can collaborate with other
stakeholders such as Clay County, FDOT, etc. to install the trunk main infrastructure during or near the
construction of the roadways.
la
$ In addition, staff determined constructing these projects in close succession will develop the trunks
L necessary to support this substantial service grid. Service grids provide alternate service pathways to
provide and maintain service in the event of pipeline breaks or damage.Service grids also provide redundant
support for areas during times of high-water demand.
CCUA's current Service Availability Policy (SAP) requires developers to install the infrastructure
necessary to serve their developments and dedicate that infrastructure to CCUA for operation and
maintenance. The SAP allows for CCUA to participate in those developer driven projects by requiring
upsizing pipelines, pump stations, etc. to meet CCUA's future needs. The current SAP would require the
initial developments to install the initial trunk main infrastructure in addition to the infrastructure necessary
to support their projects. This approach places a significant upfront capital cost to development which
would either slow the pace of development or create a barrier to entry.
CCUA's consulting team, Dewberry, prepared a technical report that provided conceptual costs for the
pipelines and the cost recovery mechanism being considered in this policy.Dewberry's conceptual opinion
of cost totals $25.6M for the proposed trunk mains for the areas of development being considered.
Dewberry's technical report also identified the areas of development that would directly benefit from the
construction of the trunk mains within an initial 10-year planning horizon, which staff considers a
reasonably foreseeable forecasting period. The remaining capacity beyond the 10-year planning horizon
would indirectly benefit future areas of development.
CCUA does have precedence from other policies and projects where CCUA pioneered capital infrastructure
with reimbursement when future development occurred. CCUA pioneered capital infrastructure through
the Middleburg Service Area(MSA)Policy to connect homes and businesses in Middleburg to the Ravines
utility systems. CCUA continues to be reimbursed for those capital costs when homes and business in the
MSA connect to our systems. The second example is Water, Wastewater and Reclaimed Water
Infrastructure for Phase 1 of the improvement of Brannan Mill Boulevard, also known as the Challenger
Center/Atlantis Drive Development Area. In this example, CCUA entered into an agreement with the
X:\Administration\Strategic Planning\LAMPA Cost Recovery Polley\Presentation\EDB Proposed LAMPA Policy Final.docx
developer to pioneer the capital infrastructure.CCUA receives reimbursement for that capital infrastructure
when a developer agreement is entered into within the Challenger Center/Atlantis Drive Development Area.
Staff proposes a cost recovery policy for the LAMPA trunk mains similar to the MSA Policy, but with a
different approach to the basis of cost recovery. For CCUA pioneering the defined LAMPA trunk mains,
staff proposes recovering those costs on an Equivalent Residential Connection(ERC)basis. The proposed
policy would require future development to reimburse CCUA for the LAMPA trunk mains as part of
CCUA's Developer Agreement (DA) process. In the DA process, staff would calculate the ERC used by
each development and a LAMPA cost per ERC would be applied. The proposed policy requires payment
of the LAMPA costs when the DA is finalized for approval by the Board of Supervisors.
The Dewberry team evaluated the developable areas directly benefiting from the LAMPA trunk mains.
Dewberry's evaluation included information from Clay County's adopted LAMPA as well as from
representatives of the largest landowner. Final land densities cannot be known at this time and are subject
to numerous variables not controlled by CCUA. Therefore, the evaluation included a sensitivity analysis
of outcomes using low,medium,and high densities,and ultimately selected an overall median level density
for the potential developable ERCs for each developable area. We consider this a reasonable basis for the
evaluation and the cost recovery in the policy.
Our legal team Sundstrom and Mindlin,LLP,prepared a proposed policy that requires staff to report to the
Board of Supervisors each year summarizing the costs of the LAMPA trunk main projects expended to date
as well as the ERC costs recovered to date. The proposed policy provides the Board of Supervisors the
ability to update annually the associated costs, including interest carrying charge adjustments, as well as
ERC-based adjustments,if warranted,based upon how the pattern of development is occurring.
Staff along with the Dewberry and legal teams consider stakeholder input important to the success of this
policy and its implementation to pioneer the trunk main infrastructure to benefit the area. We seek Board
of Supervisors authorization to advertise and hold a public workshop to engage and receive stakeholder
comments regarding the proposed LAMPA Capital Cost Recovery Policy.
Staff would hear, evaluate, and incorporate relevant comments and improvements into the proposed
LAMPA Capital Cost Recovery Policy. Staff would then return to the Board of Supervisors after the
workshop with an updated policy and request authorization to proceed with a public rate hearing for
consideration of the LAMPA Capital Cost Recovery Policy.
Should the Board of Supervisors not want to consider the proposed LAMPA Capital Cost Recovery Policy,
staff would continue to support development and expansion of CCUA's utility systems through the existing
SAP method. Any cost participation or potential pioneering of capital infrastructure would remain within
CCUA's existing SAP and DA processes.
REQUEST:
Staff respectfully requests the Board of Supervisors authorize staff to advertise and hold a public workshop
to engage the interest of public stakeholders for input and comments on the proposed LAMPA Capital Cost
Recovery Policy.

LAKE ASBURY MASTER PLAN AREA
TRUNK MAIN CAPITAL COST RECOVERY POLICY
THIS LAKE ASBURY MASTER PLAN AREA TRUNK MAIN
CAPITAL COST RECOVERY POLICY (Policy) is adopted in connection with
the extension of the First Coast Expressway (FCE) on a generally north/south axis
within the Lake Asbury Master Plan Area (LAMPA), as well as associated arterial
and collector roadways (a planning purpose map of which is attached hereto as
Exhibit A), and which is wholly within the service area of Clay County Utility
Authority (Authority). The LAMPA acreage is approximately 30,000 acres. It is
recognized that the LAMPA is poised for the development of approximately 30,000
equivalent residential connections (ERCs)(the density factor) over a 25-year period,
with an estimated 12,000 new ERCs projected within the next 10 years. In
recognizing the Authority's obligation to provide potable water, wastewater and
reclaimed water utility service throughout its service area, and in recognition that
the largest cost savings available to the Authority and its ratepayers is to build major
trunk lines in conjunction with the construction of said FCE and associated arterial
and collector roadways, where appropriate, and/or upgrade or otherwise improve
existing Authority system infrastructure to adequately meet increased demands
resulting from the LAMPA development, the Authority hereby finds that the
adoption of an appropriate trunk main capital cost recovery Policy is in the public
interest and a proper exercise of the duties assigned to the Authority by the Florida
Legislature by its adoption of Chapter 94-491, Laws of Florida, Special Acts of
1994.
This Policy is intended to be a supplement to the Authority's existing Service
Availability Policy (SAP), as may be amended from time to time, for the purpose of
establishing a fair and equitable method to recover costs from immediate benefitting
users associated with the extension of and/or improvements to the trunk potable
water, wastewater, and reclaimed water mains and ancillary facilities necessary to
provide service to the LAMPA as defined in Clay County's Future Land Use Policy.
This policy is necessary to position the Authority to provide service to the LAMPA
via new pipeline extensions and/or improvements to existing infrastructure on an as-
needed basis. It is also necessary to place the Utility Authority in position to deliver
its services on a cost-effective basis as required at the time hereof and thereafter.
Financial feasibility will require that the Authority address each future phase of the
LAMPA service area development on an as-needed basis.
1. Intent: It is the intent of the Authority to extend backbone master trunk
potable water, wastewater and reclaimed water mains in conjunction with the
extension of the FCE, and associated arterial and collector roadways within the
LAMPA (the Project), and/or upgrade of improving existing Authority system
infrastructure, subject to budget restraints and financial feasibility and that a cost
recovery program be established to equitably apportion the cost of the trunk main
and associated transmission distribution, and collection system infrastructure
identified preliminarily in the Dewberry Lake Asbury Master Plan Area Trunk Main
Engineering Report, attached as Exhibit B, to all properties receiving the benefit of
that service.
2. Purpose: It is the purpose of this Policy to satisfy Florida's dual
rationale nexus test. The Authority hereby finds that it has properly documented:
(i) the anticipated potential growth within the LAMPA; (ii) that participation in the
LAMPA trunk main capital cost recovery policy is necessary to serve that growth;
(iii) that the Authority, its staff and consultants, have performed a diligent analysis
of the pro rata cost of the participation in the LAMPA trunk main capital cost
recovery project; (iv) that the intended charges to new users within the LAMPA are
a fair appropriation of the cost of participating in the Project; (v) that the funds to
be collected will primarily benefit new development; and (vi) all funds collected
pursuant to this Policy will be disbursed to recover the capital costs expended to
serve the growth within the LAMPA.
3. Applicability: This Policy shall apply to those properties found to have
immediate direct benefit from the installation of one or more of the master trunk
mains as defined in Section 1.1 of Exhibit B and displayed generally in Exhibits B-
1, B-2 and B-3.
4. Cost Recovery System: In order to equitably allocate the costs, it is
essential to establish a preliminary trunk main alignment and system design and
based on that design, to establish a cost estimate to serve the entire LAMPA. It is
also understood that future development obstacles, rights of way or easement
acquisition issues, site acquisition, and development patterns may alter the final
design, location and routing of trunk main and associated distribution and collection
systems; however, the Authority finds that, based upon engineering studies
commissioned heretofore, that the cost estimates established herein are a fair
representation of the infrastructure cost for the LAMPA. The preliminary
infrastructure construction cost estimates for trunk mains identified along the
existing CR 218 and the proposed extension, the proposed Cathedral Oaks Parkway,
and corridors to the north of the interchange with the FCE is estimated in the
Dewberry Engineering Report (Exhibit B) at $25.6 million. The cost recovery
mechanism shall be calculated by utility. The potable water estimated apportioned
cost of$5,807,000 over 8,897 ERCs yields an estimated trunk main and associated
cost of $653 per ERC in present money value. The reclaimed water estimated
apportioned cost of$7,915,000 over by 8,897 ERCs yields an estimated trunk main
and associated costs of$890 per ERC in present money value. The wastewater cost
recovery mechanism for the estimated apportioned cost of$9,817,000 over 12,190
ERCs yields an estimated trunk main and associated costs of $805 per ERC in
present money value. The costs not apportioned to ERCs within LAMPA under this
Policy will be allocated according to CCUA's existing Service Availability Policy
at the time of entrance into future developer agreements.
5. Payment: Payment of the charges required hereunder shall be due and
made at the time that the Authority signs off on the permitting of the potable water
or reclaimed water distribution or wastewater collection system applicable to any
parcel within the LAMPA for such uses as residential neighborhoods, multifamily
housing, and any and all commercial, industrial, hotel, hospital or other such uses.
6. Annual Adjustments: The cost per ERC shall be adjusted annually so
as to recover the Authority's carrying costs on the Authority's investment in the
subject infrastructure, and to adjust from estimated costs to actual costs, taking into
consideration the following:
(a) Financing/Carrying Costs: The financing/carrying costs to be
established based on the following priority as applicable to the specific
situation from time to time. The rate shall be:
(1) 1-1/2% above the True Interest Cost (TIC) of the transaction
which financed the project, or
(2) 1-1/2% above the TIC of the most recent capital financing
transaction of the Clay County Utility Authority, or
(3) 1-1/2% above the variable rate of the Bond Market Association
Municipal Swap Index (formerly PSA) at the website
www.bondmarkets.com/research/psaswap.shtml
(b) Density: The Authority shall annually adjust the density factor in
accordance with then-approved development entitlements for the
properties within the LAMPA subject to being benefitted hereby.
(c) Timing of Annual Adjustments: The inflation, carrying cost, actual vs.
estimated cost and density adjustments will be established on July 1st
each year and will be presented at the Authority's Annual Budget and
Rate Increase Public Hearings.
(d) The Authority reserves its lawful right to amend its rates and charges
hereunder so as to impose fees that are just, equitable, compensatory,
and not unduly discriminatory.
7. Rights of Way: The Authority has made it a standard of practice that
where utility extensions occur adjacent to existing or future major roadways, it will
use its best commercially feasible efforts to secure easements to accommodate such
extensions. It is prudent to do so considering the likelihood that new roadway
projects will be displaced or require expensive relocation of utilities placed within
the rights of way. In keeping with this standard, the Authority will require
developments subject to this Policy, which front on such roadways to provide
easements to the Authority to accommodate its utility extensions. The Authority, at
its sole discretion, may elect to substitute fulfillment of this requirement from time
to time for specialized parkway segments that include extensive right of way with
full width required for all potential lane expansions and that leave sufficient
dedicated rights of way space for all contemporaneous or future utility needs outside
the furthest potential lanes and in a manner contemplated for both efficient
transportation and utility construction and maintenance.
8. Other charges: This Policy is designed to create an equitable allocation
of the cost of the extension of the Authority's backbone master trunk potable water,
wastewater, reclaimed water distribution and collection and storage systems through
the LAMPA and is not intended to replace any of the other charges covered by the
Authority's current SAP. Therefore, all other service availability charges, including
connection charges, meter installations charges, inspection fees, plan review fees,
fire flow connection fees, etc., are applicable to projects within the LAMPA.
9. Limitations: Service will be extended within close proximity of all
portions of the LAMPA, but will not necessarily extend fully to each parcel. The
developer shall bear the cost of all on-site installations and off-site extensions to the
nearest connection point. For certain situations where future developments are
likely, and there is sufficient demand for service, the Authority may elect to invest
in infrastructure extensions and/or improvements on a cost sharing basis, as above.
10. Existing Residential Houses: Residences within the LAMPA with
Certificates of Occupancy issued prior to official notice of the availability of service
will not be required to connect to the Authority's system when service becomes
available. However, optional connection will be available at any time and as an
incentive for the owner to disconnect and discontinue use of any existing package
plants, drain fields, septic tanks and the like, if the property owner elects to connect
to the Authority's potable water, wastewater and/or reclaimed water service when
available to the property, the service availability charges will be determined,
assessed and financed by the Authority over a 10-year period.
11. Pump station sites: All necessary pump station sites required to
implement this Policy shall be dedicated to the Authority at the sole cost and expense
of the benefitted land owner(s) as a condition to receiving utility services from the
Authority of the adjoining property. To the extent that such pump station sites
benefit neighboring properties, the Authority shall charge and collect from such
neighborhood property owners their pro rata share of the fair value of such sites on
a refundable advance basis to the donor consistent with the Authority's SAP.

1. Introduction
In November 2006, the Clay County Board of County Commissioners adopted the current Lake Asbury
Master Plan (Master Plan), which includes various policies covering future land use (LA FLU), community
facilities (LA CFE), and conservation (LA CON). The Lake Asbury Master Plan Area, or LAMPA, is
approximately 30,000 total acres, bounded by Black Creek to the north and west, Peters Creek to the
east, and State Road (SR) 16 to the south.
The entirety of the LAMPA is within the Clay County Utility Authority service area. To reiterate CCUA's
obligation to provide utility services, LA FLU Policy 1.3.2 states, "The Clay County Utility Authority[CCUA]
shall provide potable water and wastewater facilities necessary to meet future demands."
The development plan for LAMPA includes a mix of residential, commercial, municipal, and recreational
uses. The current Future Land Use Map (FLUM), adopted in March 2022 and shown as Figure 1.1,
shows most of the higher density suburban development concentrated in the south and east quadrants
along the corridor of the future First Coast Expressway (FCE), currently under construction by the Florida
Department of Transportation (FDOT). The north and west quadrants are slated to remain predominately
lower density rural.

CCUA seeks to support the success of the Lake Asbury development by pioneering key potable water,
wastewater and reclaimed water transmission mains in the vicinity of the impending County Road (CR)
218 extension and Cathedral Oak Parkway, which will serve as east-west collector roads for the new
FCE. CCUA expects those roads, which are slated to be complete by late 2024, will spur a significant
increase in development along those corridors. Recognizing that the most expeditious and economical
means of installing new utility infrastructure is in conjunction with planned projects, CCUA identified four
corridors for inclusion in this feasibility and sizing evaluation that are within existing project scopes or
rights of way/easements, as shown in Figure 1.2.

1.1 Objective
This Lake Asbury Master Plan Area Trunk Main Engineering Report evaluates both the current and future
demands for potable water, wastewater and reclaimed water suggested in the LA FLU Policy to
determine what trunk mains may be needed in the four target corridors identified by CCUA; the
appropriate sizing of those trunk mains; and whether any existing infrastructure requires improvements to
meet CCUA's obligation to provide potable water, wastewater and reclaimed water services in the LAMPA
development through the full build-out by 2040. This Engineering Report includes the location, size and
demand for projects deemed necessary for the total projected build-out of the LAMPA as outlined in the
Master Plan; identifies the areas in the LAMPA that will most immediately directly benefit from the
recommended projects; and provides a planning level capital cost estimates for those projects with a
proposed apportionment of those costs to the ERCs projected within immediate benefitting areas. For the
purposes of this analysis, "immediate direct benefit" is considered development anticipated within the next
10 years that would be dependent on the availability of one or more of the proposed trunk mains. CCUA
chose 10 years as a reasonably foreseeable planning period, as opposed to a 15-or 20-year period,
which it considers to be more speculative.
2. Existing Conditions and Planned Improvements
2.1 Potable Water System
CCUA anticipates most of the potable water supplied to the LAMPA will originate from two existing water
treatment plants (WTP): Meadow Lake (formerly known as Lake Asbury) and Peters Creek (formerly
known as Green Cove West), as well as a third plant, Saratoga Springs, that is projected to be in service
Dewberry. Page 4 of 15

Trunk Main Engineering Report
in 2023. CCUA has upgrades under construction at the Meadow Lake WTP, however those
improvements are focused on redundancy and reliability and will not increase design capacity. CCUA is
planning an expansion at the Peters Creek WTP to increase the total permitted maximum day operating
capacity to 4.03 MGD. These plants and associated improvements are described in greater detail in
Table 2.1.1. Figure 2.1.1 shows the existing potable water system in the vicinity of the LAMPA.

2.2 Wastewater System
CCUA has two advanced wastewater treatment(AWT)Water Reclamation Facilities (WRF)whose
service areas include the LAMPA: Mid-Clay Regional WRF (FDEP ID FLA011377) and Peters Creek
WRF (FDEP ID FLA327841, formerly known as Green Cove West).
CCUA has a project in design to increase the wastewater treatment capacity of the Mid-Clay WRF from
1.5 to 3.0 MGD. Additionally, CCUA plans to replace the 0.2 MGD Peters Creek WRF with a new
expandable regional facility with an initial capacity of 1.5 MGD. This regional facility will be expandable up

2.3 Reclaimed Water System
CCUA is deeply invested in the continued growth of its reclaimed water system, recognizing that full
reclaimed utilization helps ease demands for potable water, thereby reducing reliance on the Floridian
Aquifer and forestalling the need for more expensive alternative supply techniques. The CCUA Service
Availability Policy requires installation and use of reclaimed water facilities in new developments, which is
reiterated in the LA CFE Policy 1.2.2.
Public access reuse (PAR)water in the LAMPA is expected to be supplied by CCUA's two AWT WRFs,
Mid-Clay and Peters Creek, and the Saratoga Springs Reclaimed Pumping Facility (RPF). The Saratoga
Springs RPF will provide supplemental PAR from either a groundwater well or from treated water received
from Mid-Clay. These plants and associated improvements are described in greater detail in Table 2.3.1.

3. Hydraulic Modeling and Trunk Main Sizing
The hydraulic model is a vital tool for understanding CCUA's potable water, reclaimed water, and
wastewater systems' hydraulic behavior. It is also crucial to assessing the systems' capacities in relation
to the estimated progression of the LAMPA development build-out, and in determining the feasibility and
sizing of trunk mains in the four corridors identified by CCUA. The goal of the hydraulic modeling was to
evaluate how the addition of new trunk mains in the four target corridors would support existing
customers and future LAMPA demands, while maintaining appropriate levels of service (LOS). It also
served to either affirm the sizing of existing trunk mains or suggest that improvements may be necessary.
CCUA engaged Dewberry Engineers, Inc. to update its current potable water, reclaimed water, and
wastewater models based on CCUA's planned facility improvements. Beyond this immediate project,
these updated hydraulic models will assist CCUA in evaluating the future projects, develop long-range
Capital Improvement Plans, and provide minimum design standards for developments within LAMPA.
3.1 Future Demand Development
LA FLU Policy 1.1.5 states development within the LAMPA is limited to 21,281 residential units through
2040. Though the Master Plan contemplates commercial development, it does not provide an equivalent
unit-based cap. Table 3.1.1 provides the range of allowable land use densities as shown in LA FLU
Policy 1.4.1, as well as the estimated total developable acreage. Dewberry worked with CCUA to
calculate estimated "developable acreage" based on a high-level evaluation of property characteristics
within LAMPA. Lands with one or more of the following attributes were omitted from the calculation of
developable acreage:
• Development restricted based on land use (e.g. Lake Asbury Greenway- LA GW).
to • Existing approved subdivision developments that are not subject to the requirements of the
Master Plan pursuant to LA FLU Policy 1.4.13.
• Lands typically considered unsuitable for development based on environmental characteristics
such as soil type, elevation, vegetation, and/or existing high-water areas.
Also, the analysis did not consider specific development allowances or restrictions that may be in the
Master Plan, and assumed ERC calculations that totaled more than 21,281 could reasonably be
attributable to commercial development. Ultimately, the exact acreage would be confirmed by field
analysis and through the permitting process prior to any development occurring and are only identified for
planning purposes.

Based on conversations with CCUA and analysis of general development trends in Clay County, the
density ranges were converted to Equivalent Residential Connections (ERCs) as low, medium and high
singular values per net acre for each land use type, as shown in Table 3.1.2, then allocated in the model
to the land uses' developable acreage.
The methodology for setting the ERC values varied by land use type as follows:
• LA RC: Low ERC value determined by calculating the per one (1)acre equivalent of 1 unit per 5
to acres. Medium value is average of Low and High, and High value is Master Plan maximum density.
• LA RF: Low and High are Master Plan densities; Medium is their average.
• LA MPC: Because the Master Plan contained two ranges for this land use, the Low and High values
are the base and maximum across both ranges. The Medium represents the average of the base and
maximum for Single-Family Detached, which most closely represents CCUA's understanding of
current typical development patterns in Clay County.
• LA VC: Similar to LA MPC, the Low and High values are the base and maximum across both ranges
provided for this land use. The Medium value is the average of the Single-Family Detached range
average and the Single-Family Attached/Multifamily range average.
• LA AC: The Master Plan density table provides a base, middle and maximum value in the range for
this land use.
Additionally, since commercial square-footage is not known, all net acreage was converted to ERCs.

Future demands were developed using an annual average daily flow (AADF)gallons per day (GPD) per
ERC for potable water, wastewater, and reclaimed water. The flows per ERC utilized in the updated
hydraulic models were based on engineering judgement, CCUA historic billing data, and consultation with
CCUA staff.
3.2 Potable and Reclaimed Water
3.2.1 Potable and Reclaimed Water Model Development
CCUA's existing potable and reclaimed water models were developed in InfoWater Pro and use the
Hazen-Williams equation to calculate flows, pressures, head loss, and velocities in the pipes and
junctions. The goal of the hydraulic modeling was to evaluate how the addition of new potable and
reclaimed water trunk mains in the four target corridors would support existing customers and future
LAMPA demands, while maintaining appropriate levels of service (LOS). It also served to either affirm the
sizing of existing potable water mains or suggest that improvements may be needed.
The modeling focused on the main distribution trunk lines with stub-outs to the proposed developable
areas; internal distribution piping for the developable areas were not included. Because of this, the
to hydraulic analysis did not consider fire flow and focused on the peak hour demand scenario that would be
applicable for major trunk mains.
The scenarios used to evaluate the future conditions included Average Daily Demand (ADD) and Peak
Hour Demand (PHD) and are explained further in Table 3.2.1. The main trunk lines were sized to handle
the PHD.

were then spatially apportioned based on the estimated developable acreage in conjunction with
engineering judgment and CCUA input.

Trunk Main Engineering Report
An integrated looped potable water system was developed looping the Meadow Lakes WTP, Peters
Creek WTP, and the Saratoga Springs WTP currently under construction. Similarly, an integrated
reclaimed water system was developed by looping the Mid-Clay WRF, the future Peters Creek WRF, and
the Saratoga Springs RPF that is under construction.
The analysis considered the total estimated demands at the LAMPA build-out to evaluate the hydraulic
sufficiency, and main trunk lines were evaluated for location and size, while maintaining the required LOS
throughout the integrated and looped potable and reclaimed water distribution systems.
3.2.3 Potable Water Trunk Main Sizing
The results of the hydraulic analysis found that the addition of potable water trunk mains is necessary in
three of the four proposed corridors to support the full LAMPA build-out and are particularly critical to
pioneer utilities that will allow for the development anticipated within the next 10 years.
The model indicates a 16-inch potable trunk main is needed from the western limit of the CR 218
Extension running eastward, where it would connect to a 16-inch potable trunk main proposed for
Corridor 1 (shown in red on the Figure 1.1.1). That main would run north then turn east via an existing
casing under the FCE, finally turning north again to its terminus at the Saratoga Springs WTP.
The analysis for Corridor 2, shown in black on Figure 1.1.1, indicates a 12-inch potable trunk main is
necessary to convey flows south from the Saratoga Springs WTP and connect to a short run of a 12-inch
main on Cathedral Oak Parkway (blue on Figure 1.1.1), running west approximately 1,550 LF to a dead
end pending a future connection to support for development to the south.
Exhibit B-1 presents the proposed alignment of the potable water trunk mains, the estimated directly
benefitting developable areas and the number of ERCs associated with those areas. The estimated
to capital costs are detailed in Table 3.2.2. The total estimated capital cost for potable water trunk mains is
$6,596,400. All dollar values are estimated and rounded up to the nearest thousand.

3.2.4 Reclaimed Water Trunk Main Sizing
The hydraulic analysis for the reclaimed water system indicated the same corridors as potable water are
necessary, with some slightly different pipe sizes and a few notable additions. An additional segment of
reclaimed main is necessary east of the existing CR 218 to Shadowlawn Elementary, as well as from the
existing CR 218 intersection with Shadowlawn Drive north to the vicinity of Henley Road.
The trunk main alignments are illustrated in Exhibit B-2. The estimated capital costs for the installation of
new reclaimed water trunk mains are presented in Table 3.2.3. The total estimated capital cost for

3.3 Wastewater
3.3.1 Wastewater Model Development
CCUA's existing wastewater model, developed in InfoSewer, uses the Hazen-Williams equation to
to calculate flows, pressures, head loss, and velocities in the pipes and junctions in the model. The existing
model contained both gravity systems and force main systems that contribute flows to the two WRFs that
will serve the LAMPA, Mid-Clay and Peters Creek.
The hydraulic analysis for the wastewater system anticipates expanding the Mid-Clay service area for
LAMPA developments west of the FCE and north of CR 218, and the Peters Creek service area for
developments east of the FCE and predominantly south of CR 218.

3.3.2 Future Demand Allocations
Future demands were allocated from the ERCs calculated from each land use's densities. Those ERCs
were then spatially allocated based on the estimated developable acreage in conjunction with engineering
judgment and CCUA input. The analysis of the full LAMPA demands was used to evaluate the hydraulic
sufficiency, and accordingly the main trunk lines were sized while maintaining the required LOS
throughout the system.

Trunk Main Engineering Report
3.3.3 Wastewater Force Main Sizing
The initial evaluation of the four trunk main corridors revealed that force mains in Corridors 1 and 2 (red
and black on Figure 1.1.1)would be unnecessary due to the existing service area boundaries of Mid-Clay
and Peters Creek WRFs. Therefore, the model used the hydraulic standards shown in Table 3.3.1 to
facilitate sizing of the force main in the CR 218 Extension and along the planned Cathedral Oak Parkway,
which will be an east-west connector between the FCE and CR 315.
For the CR 218 Extension, the hydraulic analysis calls for a 10-inch force main from the eastern terminus
of the project (near the FCE interchange) running west approximately 1,100 LF, transitioning to a 12-inch
force main to connect with the existing force main system on CR 218. A 1,700 LF section of 10-inch force
main is needed from Shadowlawn Elementary to move flow east to the existing CR 218 system, which will
convey flows north to Mid-Clay.
On the east side of the FCE, the model suggests a 6-inch force main from the Cathedral Oak/FCE
interchange, increasing to short run of 10-inch force main before transitioning to 16-inch to connect to the
existing 12-inch force main system on CR 315, which will move flows south to Peters Creek.
However, that existing 12-inch force main can only accommodate an additional flow equivalent to roughly
1,250 ERCs before reaching maximum operating capacity. This is insufficient to support the projected
build-out of the portion of the LAMPA that would be served by this force main system in addition to the
dependent developments outside of LAMPA. To adequately convey future flows from within the LAMPA,
as well as additional development projected outside the LAMPA boundary, the model indicates the
system will require approximately 9,100 LF of 20-inch force main parallel to the 12-inch along CR 315, to
run south and connect to a 24-inch force main to convey flow west to Peters Creek WRF.
The wastewater trunk main alignments are illustrated in Exhibit B-3. The estimated capital costs for the
to installation of new wastewater water trunk mains are presented in Table 3.3.2. The total estimated capital
cost for wastewater trunk force mains is$10,526,000. All dollar values are estimated and rounded up to
the nearest thousand.

4. Report Summary and Recommendations
Based on the results of the hydraulic modeling, the immediate and future development of the Lake Asbury
Master Plan Area is reliant on the installation of several key trunk mains for potable water, wastewater,
and reclaimed water. Without this critical infrastructure, CCUA cannot commit to provide those services in
a timely and cost-effective manner within the LAMPA.
CCUA has elected to pioneer these trunk mains to ensure they are in service in a timely fashion to
support impending development in the LAMPA, rather than await installation by private entities under its
to existing Service Availability Policy. A summary of recommended trunk mains and their associated total
capital costs is presented in Table 4.1.
CCUA directed Dewberry to fairly and equitably apportion the estimated costs of the recommended trunk
mains to the ERCs projected to develop within the next 10 years and thus most immediately benefit from
the availability of service. The utilities were evaluated independently, so that the costs are apportioned
only amongst those ERCs that would benefit from a particular utility service.
More specifically, Dewberry calculated, to the best of their ability and based upon local information
available at the time, the number of ERCs dependent on the availability of each trunk main, then
calculated the percent of each trunk main's total capacity that would be required by those ERCs. That
percentage was then applied to the total cost of each main, then divided by the number of ERCs to
produce a cost per ERC as shown in Table 4.2. The number of ERCs presented in Table 4.2 represent
the Medium values as described in Section 3.1 — Future Demand Development, and shown in Table
3.1.2. Exhibits B-1, B-2 and B-3 provide the estimated Low, Medium and High ERC values and the
corresponding estimated costs per ERC.
The calculation of the cost per ERC for potable water, reclaimed water, and wastewater trunk main
availability is designed to have a rational nexus both as to the need for additional capital facilities and as
to the expenditure of funds collected and the benefits accruing to the first phases of development within
the Lake Asbury Master Plan Area.
