Item 1– Clarke County Request for Water and Sewer Service
Frederick County has received a request from Clarke County to authorize Frederick Water to provide public
water and sewer service for approximately 350+/- acres (zoned Highway Commercial) in the Double Tollgate
area. Specifically, this area is located at the intersection of Stonewall Jackson Highway (Route 522), Lord
Fairfax Highway (Route 340) and Fairfax Pike (Route 277). The requested water and sewer capacity is
150,000 gallons per day. Currently, Frederick Water provides public water service to the former “Camp 7
State Correction Facility” property in Clarke County.
Frederick County’s Sewer and Water Service Area (SWSA) is a growth boundary, and as outlined in the 2035
Comprehensive Plan, it designates the limit of where public water and sewer could be extended. The
County’s current SWSA boundary for this area surrounds only the Lake Frederick development. The Crooked
Run Wastewater Treatment Plant (CR-WWTP) provides sewer service to Lake Frederick and is located within
this development. A 12” water main currently exists along Route 277 to the Clarke County line and the new
elevated water tank is also located in the vicinity.
The Double Tollgate area requested by Clarke County is not adjacent to the limits of the SWSA, as shown in
the Southern Frederick Land Use Plan (SFLUP). There are approximately 200 acres at the corner of Route
522 and Route 277 in Frederick County that are outside the current limits of the SWSA which lie between
the Crooked Run SWSA and the requested Clarke County properties. The properties in Frederick County are
planned for future mixed use and industrial.
Staff has received comments from Frederick Water (attached) pertaining to this request; three scenarios are
outlined below.
Scenario 1: Only the requested properties in Clarke County– 350 acres at Double Toll Gate, 150,000 GPD –
utilizing the CR-WWTP.
Scenario 1 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick Water’s
water and sewer services.
Water service is available via a 12-inch water main adjacent to Route 277.
The limited 150,000 gallons per day (GPD) sanitary sewer flow requested and proximity of the CR-
WWTP would suggest that Clarke County sanitary flows could be accommodated most easily at CR-
WWTP.
Sanitary sewer infrastructure would need to be constructed to convey the flows from the Clarke
County properties to CRWWTP; this is a financial responsibility of Clarke County and/or the property
owners and developers.
The CR-WWTP would need to be upgraded/expanded to accommodate the additional wastewater
flows. The developer of Lake Frederick, by existing agreement, would be the party responsibility for
granting permission to utilize the CR-WWTP as well as for the financing for upgrading the CR-WWTP.
If this scenario is selected, Clarke County and Lake Frederick’s developer will need to achieve
agreement regarding access to CR-WWTP and funding the treatment plant upgrade to accommodate
the 150,000 GPD.
3
Scenario 2: Clarke County properties and the area south of Route 277 that adjoins the Crooked Run SWSA
(approx. 200 acres).
Scenario 2 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick Water’s
water and sewer services and includes a potential for up to 100,000 GPD of water and sewer to
support approximately 200-acres of SWSA-expansion within Frederick County.
Water service is available via a 12-inch water main adjacent to Route 277.
The expanded SWSA when combined with Clarke County’s flow brings additional demands to
250,000 GPD. This sanitary sewer flow increase may be too much for an expanded CR-WWTP to
accommodate due to the plant’s limited discharge abilities; too much discharge could overwhelm
the existing receiving creek. Further studies, DEQ discharge permit amendments, and an agreement
with Lake Frederick’s developer and Clarke County would be necessary. CRWWTP upgrade would be
needed. CR-WWTP would presumably operate more efficiently with the increased sanitary flows.
The alternative wastewater treatment solution for Scenario 2 would be at the Parkin Mill
Wastewater Treatment Plant (PM-WWTP). PM-WWTP has adequate available treatment capacity.
Although the limited projected sanitary sewer flows (250,000 GPD) would probably not support the
necessary financial investment to construct the sanitary sewer pump station, force main, and gravity
line needed to convey the wastewater to PM-WWTP.
Scenario 3: Clarke County properties and the entirely of the Route 277 triangle area – all effluent would go
to the PM-WWTP.
Scenario 3 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick Water’s
water and sewer services and includes a potential for up to 1.3 MGD of water and sewer to support
an approximately 700-acres of SWSA-expansion within the 277-triangle area of Frederick County.
This would result in nearly 1.5MGD of water and sewer demands.
The expanded SWSA when combined with Clarke County’s flow brings additional wastewater
treatment demands to 1.5 MGD. This sanitary sewer flow increase would be too much for an
expanded CR-WWTP. The sanitary sewer flows would need to be conveyed to PM-WWTP. PM-
WWTP has adequate available treatment capacity in the short term but would require an expansion
in the future.
At least two sanitary sewer pump stations, force mains, and a gravity sewer line would need to be
constructed to convey the wastewater to PM-WWTP. These significant improvements would be
funded by the benefiting developers and property owners. As this will result in significant economic
development and tax revenue opportunities for both Counties, County contributions – possibly
utilizing American Rescue Plan Act of 2021 funds – could be considered.
Staff is seeking comments and recommendations from the CPPC on this request and the outlined scenarios.
Please contact staff if you have any questions or need additional information.

Water At Your Service
MEMORANDUM
TO: Candice Perkins, Assistant Director of Planning
FROM: Eric R. Lawrence, Executive Director
SUBJECT: Proposed Water and Sewer Service to Clarke County
DATE: April 1, 2021
While Frederick Water operates independently of Frederick County, the County does establish
the policy limits of where Frederick Water’s public water and sewer services may be provided.
It is this limits-of-service policy element that prompts the Frederick County Board of
Supervisors’ to request input from Frederick Water as part of consideration of Sewer and Water
Service Area (SWSA) boundary adjustments, and in the Clarke County request, exceptions to
the SWSA and political boundary limitations. Thank you for considering Frederick Water’s input
as Frederick County evaluates Clarke County’s request.
Clarke County’s February 16, 2021 request to access Frederick Water’s water and sewer service
for the Double Tollgate area of Clarke County could create opportunities for both Clarke and
Frederick Counties. Frederick Water has systemwide wastewater treatment capacity of 11
Million Gallons per Day (11 MGD). The limited 150,000 gallons per day (GPD) sanitary sewer
flow requested by Clarke County would certainly, but only slightly, detract from wastewater
treatment capacities that could be utilized by Frederick County development. It should be
noted that the SWSA expansion benefit is proportional to the level of financial commitment
offered by both jurisdictions, their property owners and developers- the larger the SWSA
expansion, the greater the infrastructure cost, the more property owners who will benefit and
who will contribute to the infrastructure costs, and the greater potential for commercial and
industrial development generated tax revenue.
In your e-mail of March 30, 2021, you identified three scenarios for how the SWSA could be
adjusted in response to Clarke County’s request. Below I provide thoughts from Fredrick
Water’s perspective for each of the scenarios, based on future land uses identified in the 2035
Comprehensive Plan. Much of the information is derived from Frederick Water’s 2017 Sanitary
Sewer Master Plan.

S cenario 1: Only the Clarke County properties – 350 acres at Double Toll Gate,
150,000 GPD – utilizing the Crooked Run Plant. These properties do not touch the
current Crooked Run SWSA. With this first scenario – helpful background
information would be: ability to expand this plant, impact the expansion of this
plant on other County plants, agreements needed to expand this plant (FW, FCSA,
Developer).
Scenario 1 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick
Water’s water and sewer services.
Frederick Water has an existing 12-inch water main adjacent to Fairfax Pike (Route 277) which
terminates at the Clarke County boundary, approximately 550-ft west of the Dinosaur Land
property. Water supply would be supported by the existing Diehl and Anderson Water
Treatment Plants, a future well water treatment plant located within Lake Frederick, and the
under-construction Sliwinski Water Treatment Plant. A recently constructed 500,000-gallon
elevated water storage tank supports this 12-inch water main and is located less than 5,000
feet from Clarke County boundary. Water supply and service is available.
The limited 150,000 gallons per day (GPD) sanitary sewer flow requested and proximity of the
Crooked Run Wastewater Treatment Plant (CR-WWTP) would suggest that Clarke County
sanitary flows could be accommodated most easily at CR-WWTP. Sanitary sewer infrastructure
would need to be constructed to convey the flows from the Clarke County properties to CR-
WWTP; this is a financial responsibility of Clarke County and/or the property owners and
developers. The CR-WWTP would need to be upgraded/expanded to accommodate the
additional wastewater flows. The developer of Lake Frederick, by existing agreement, would be
the party responsibility for granting permission to utilize the CR-WWTP as well as for the
financing for upgrading the CR-WWTP. If this scenario is selected, Clarke County and Lake
Frederick’s developer will need to achieve agreement regarding access to CR-WWTP and
funding the treatment plant upgrade to accommodate the 150,000 GPD.
Frederick Water would own the water distribution lines and the sanitary sewer conveyance
lines from the user’s properties to the treatment plant. Frederick Water operates the CR-
WWTP.

Scenario 2: Clarke County Properties (350 ac) and the area south of 277 that adjoins
the crooked run SWSA (attached maps) (approx. 200 acres). Can Crooked Run serve
both areas - same questions as above. If Crooked run isn’t able to handle this, what
would it take to go to Parkins Mill.
Scenario 2 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick
Water’s water and sewer services and includes a potential for up to 100,000 GPD of water and
sewer to support approximately 200-acres of SWSA-expansion within Frederick County.
Frederick Water has an existing 12-inch water main adjacent to Fairfax Pike (Route 277) which

Frederick Water would own the water distribution lines and the sanitary sewer conveyance
lines from the users to the treatment plant. Frederick Water operates the CR-WWTP and PM-
WWTP.
Scenario 3: Clarke and the 277 triangle area added and it all goes to Parkins Mill –
what would it take to go this route.
Scenario 3 addresses Clarke County’s request for 150,000 gallons per day (GPD) of Frederick
Water’s water and sewer services, and includes a potential for up to 1.3 MGD of water and
12

sewer to support an approximately 700-acres of SWSA-expansion within the 277 triangle area
of Frederick County. This would result in nearly 1.5MGD of water and sewer demands.

lines from the users to the treatment plant. Frederick Water operates the PM-WWTP.
As described above, Frederick Water stands ready to accommodate an expanded Sewer and
Water Service Area (SWSA), and extension of services into Clarke County, if the Frederick
County Board of Supervisors desires to grant the expansion and extension of services as
requested by Clarke County. Like any land use plan and SWSA expansion, implementation of
the planned development scheme is driven by property owner interest in developing their
property.
Please contact me with questions.
Thank you.

The Clarke County Board of Supervisors voted on February 16, 2021 to formally request permission from
the Frederick County Board of Supervisors for Frederick Water to provide public water and sewer to the
Double Tollgate area of Clarke County. We understand that Clarke County will need to develop an
agreement with Frederick Water for this service and that approval by your Board of Supervisors is the first
step in this process.
The area to be served is approximately 350 acres at the intersection of Stonewall Jackson Highway, Lord
Fairfax Highway, and Fairfa x Pike. The estimated water and sewer capacity needed to serve this area is
appro ximately 150,000 gallons per day. Please let me know what additional information you need to
consider our request or what meetings you would like us to attend. We appreciate, in advance , your
consideration of this request.
