MEMORANDUM
TO: Village of Briarcliff Manor, Village of Sleepy Hollow, and Village of Tarrytown
FROM: Steven Robbins, P.E., LEED AP
DATE: February 8, 2023
RE: Tri-Village Consolidation Analysis – Project Summary
Overview and Project Objective
The Villages of Briarcliff Manor, Sleepy Hollow, and Tarrytown each draw water from the New
York City Catskill and Delaware Aqueducts for their water supplies. Through a combination of
multiple Inter-Municipal Agreements (IMAs) between the Villages and informal mutual-benefit
coordination between water departments, the three Villages share in the maintenance of the
taps to each aqueduct, a common metering building, and transmission main. The shared
transmission main ends at pump stations on Neperan Road in Tarrytown that are independently
owned and operated by each Village. From there, each Village provides additional chemical
treatment for the water and pumps finished water to its respective distribution system.
This arrangement has been workable with good coordination between the Villages. However,
the growing complexity of IMAs developed for each individual capital project and significant
upcoming capital investment needs to address aging/failing infrastructure in both individual
and shared system components has driven the need to further evaluate the feasibility of
consolidation for the water supply to the three villages. This evaluation would need to examine
the financial, organizational, legal, and engineering aspects to identify a preferred plan to
consolidate shared assets for the benefit of each municipality.
The Village of Sleepy Hollow, in conjunction with Briarcliff and Tarrytown, obtained an Inter-
municipal Planning Grant to fund this study.
Project Activities
Woodard & Curran and its team of subconsultants was retained through a competitive RFQ
process to develop the following project deliverables:
• Hydraulic Model;
• Financial Model; and
• Draft IMA.
These deliverables were developed through the review of background information from each
Village, a series of collaboration meetings with staff working groups from each Village, field
inspections and testing, and engineering and financial analyses.
19
Key Findings
Hydraulic Model
A combined distribution system hydraulic model was developed for the three Villages to
analyze how flow could be distributed between the systems to reduce the need for redundant
facilities for each Village.
Based on these analyses, the preferred hydraulic option is to remove the Tarrytown pump
station from service and upgrade the Briarcliff and Sleepy Hollow pump stations to supply
Tarrytown. This eliminates the near-term need for a new pump station for Tarrytown and
improves the remaining pump station infrastructure for a longer service life.
Draft IMA
A new IMA is proposed that would supersede the existing series of agreements and define the
organizational and cost-sharing responsibilities of the Villages moving forward. The key
elements of the draft IMA are summarized in the attached Terms Sheet, and include:
• Continued use of a Tri-Village Board for administration and coordination;
• Continued execution of operations, maintenance, and capital improvements by
individual Villages;
• Consolidation of aqueduct, transmission, and pump station assets into shared
ownership based on capacity allocation;
• Remaining un-consolidated assets (ie – distribution piping and storage tanks) will
continue to be fully owned and operated by the Village that they serve;
• Consolidated assets will require up front capacity share payments between the Villages
to compensate for the value of the existing assets; and
• Ongoing operation and maintenance costs for the consolidated assets will be shared
by the Villages based on annual usage, as is currently done.
Financial Model
The Financial Model shows that through this consolidation, there is a total savings of almost
$10M between the three Villages on a 10-year net present value (NPV) basis over estimated
costs without consolidation. This is driven by the avoidance of replacement costs for the
Tarrytown pump station.
On a 20-year NPV basis, additional investments will be needed in the Sleepy Hollow pump
station, but those would be shared among the three communities and the combined savings is
still almost $18M over the costs without consolidation.
The financial model does not project beyond 20 years, but future investments will be needed
in the Briarcliff Manor pump station in the longer term, which would be shared among the three
communities.
20
These savings contribute to less pressure on water rates by avoiding unnecessary capital
expenditures and spreading the cost of future capital improvements to the supply infrastructure
over a broader base.
A summary of key Financial Model findings is attached.
Next Steps
The Woodard & Curran team is presenting the results of these studies to the three Village
Boards in February, 2023. A series of site walks for Village Board members will be coordinated
to allow the members to better understand the existing facilities.
Input from the Village Boards is necessary to determine if there is interest in continuing to
advance this consolidation planning and IMA development.
21
Draft Term Sheet
Inter-Municipal Water Supply and Transmission Services Consolidation Agreement
Villages of Briarcliff Manor, Tarrytown, and Sleepy Hollow
Below is a draft term sheet that highlights the proposed key clauses of the Inter-Municipal Water
Supply and Transmission Services Consolidation Agreement.
1. The general operating structure is such that the “Tri-Village Board” is responsible for
coordinating the administration of activities for the transmission and treatment of water to
the distribution systems of the three Villages.
2. The Tri-Village Board is not an Agency and does not currently have the authority to deliver
water or to be a designated provider of associated physical services independently. The
Tri-Village Board would serve the Villages by coordinating the administration of
operations, maintenance and capital improvements, while the Villages themselves would
execute the work pursuant to the terms of this IMA.
3. The Board’s designated responsibilities would include setting budgets for approval by the
parties, monitoring the progress of projects, coordinating the administration of the IMA,
and acting in an advisory role, but the Board would not have its own employees or the
authority to manage employees of the Villages, and would not have any right to bind the
parties to the IMA or enforce it. The Board would only have the authority to coordinate the
administration of items and contracts approved by each Village and reviewed by Village
counsel.
4. Summary of Consolidated Assets:
a. The pump station assets would be designated as “Consolidated Facilities” , and the
capital costs associated with the Consolidated Facilities shall be shared by each of
the three villages in proportion to their overall negotiated capacity shares. The
capacity shares would correspond to the amount of overall asset capacity that is
reserved for each party. The agreement will specify which parties own the assets
defined as “Consolidated Facilities”. the capital cost of all pump stations would be
jointly shared among the three villages proportional to each village’s overall
negotiated capacity share. The sharing of capital costs by each village for each
pump station would occur regardless of whether a village physically uses a portion
of the pumping capacity at each pump station.
b. The Catskill Aqueduct Connections, and associated transmission mains, metering
at Shaft 10, and chemical addition at Shaft 10 shall be considered “Consolidated
Facilities”.
See example for how costs would be shared at the end of this Term Sheet.
22
5. Other assets that do not provide water supply to more than one party (e.g. distribution
systems, storage tanks, booster stations, pressure release valves, and other assets serving
only one party) shall be solely owned and operated by the Village that they serve. Owners
of these individually-utilized assets shall be responsible for addressing any capital,
operations and maintenance (O&M), or regulatory actions needed for those assets, unless
another agreement assigns that responsibility.
6. Parties that desire to reserve a portion of the capacity of assets owned by other parties will
pay an upfront capacity payment. Such capacity payment will be based on a proportionate
share of the depreciated value of the asset. Asset valuations shall be determined based on
the asset's original cost, less accumulated depreciation that considers the age and
anticipated useful life of the asset. For example, a 20 year old asset with an original cost of
$1 million and an estimated 30-year useful life, would be valued at the original cost ($1
million) less 20 years of accumulated depreciation ($1 million x 20/30 = $0.8 million), or
$200,000.
7. The agreement will specify which parties are initially responsible for operating the assets
defined as “Consolidated Facilities” for the purposes of regulatory compliance and O&M.
The owner and designated operator of any asset may be different. Any changes in
operational responsibility, or O&M or capital interventions for these jointly owned assets
may also be recommended by the Tri-Village Board. O&M costs for these assets would be
charged by the responsible party to the other parties in proportion to the overall average
day water demand in each of the Villages during the latest twelve-month period.
23
Illustration of How the Cost Sharing in the Proposed Consolidation would work:
The following example has been prepared to illustrate how cost sharing would work. For the
purposes of this example, we have assumed that the future engineering design is such that
Tarrytown’s pumping capacity is provided by an upgraded Briarcliff Manor pump station. Under
this scenario, it is assumed that Sleepy Hollow and Briarcliff Manor are served entirely by what
are currently their own pump stations.
Up Front Capacity Share Payments
Each of the Villages’ pump station facilities would become “Consolidated Facilities.” Up-front
payments would be made by each of the Villages to one or more of the other Village(s) to
compensate for previous investments made in the assets, based on capacity shares and
considering the value of the pump stations. Tarrytown would make upfront payments to
Briarcliff Manor and Sleepy Hollow to compensate them for dedicating their pump stations as
Consolidated Facilities. Beyond these initial payments all three communities would contribute to
pump station capital work based on negotiated capacity shares. Briarcliff Manor and Sleepy
Hollow would permit Tarrytown to finance internal up-front capacity payments to reduce rate
impacts. The recent Delaware Tap Project would be rebalanced, if necessary, to distribute those
costs on a capacity basis as well. The figure below shows the amount of the near-term up-front
payments required to rebalance the Delaware Tap Project costs, and for Tarrytown reserving
capacity in the Briarcliff Manor and Sleepy Hollow existing pump station assets. In the financial
model developed by Raftelis all of these costs were assumed to be debt financed.
Primary Option Up-Front Capacity Payments

Briarcliff Manor Sleepy Hollow Tarrytown
Makes Payment
Briarcliff Manor $0 $0 $0
Sleepy Hollow $1,862,792 $0 $0
Tarrytown $3,081,835 $0 $0
Pump Station Capital Reinvestment Payments
Each Village would contribute to the cost of future pump station capital reinvestments at all of
the Consolidated Facility pump stations, regardless of whether a Village physically utilizes the
pump station needing the capital reinvestment. Further, the initial costs for connecting Tarrytown
would be shared by all three communities and the Briarcliff Manor pump station would not
require a capacity expansion. The figure below shows the total new project costs for connecting
Tarrytown to the Briarcliff Manor and Sleepy Hollow pump stations, replacing the Briarcliff
Manor and Sleepy Hollow pump stations in today’s dollars. In the financial model developed by
Raftelis all of these costs were assumed to be debt financed.

*Note the reason over 20 years BM goes net negative is because they begin paying for new SH PS in middle of that period and are not yet
benefitting from shared costs for replacement of their own station. Further under the No Further Consolidation scenario they do not have to
share in SH PS costs. Modeling would need to extend out nearly 50 years to realize the significant saving BM will achieve when they receive cost
sharing for replacement of their own PS.
