ITEM �I
PROVISION OF REGIONAL SEWER SERVICE
FROM THE SHENANDOAH DEVELOPMENT
g.,..._. -
The Frederick County Sanitation Authority (FCSA) has requested guidance from the Board of
Supervisors regarding the appropriateness of providing sewer service within the proposed Crooked
Run Regional Sewer Service Area. The proposed Crooked Run Regional Sewer Service Area
encompasses approximately 1,410 acres ofland. Ofthis acreage, approximately 1,170 acres is within
Frederick County and approximately 240 acres is within Clarke County. The acreage within
Frederick County includes the Shenandoah development; Sandy's Mobile Home Park; and additional
land on the south side of Fairfax Pike (Route 277); while the acreage within Clarke County includes
the Double Tollgate area that is being studied for commercial land use and the Camp 7 State
Correction Facility.
Information from Gilbert W. Clifford & Associates, Inc., indicates that the proposed wastewater
reclamation facility will have an ultimate design capacity of 625,000 gallons -per -day (gpd). Initially,
this facility will be constructed by the developers of the Shenandoah project to treat a wastewater
flow of 375,000 gpd. This facility would then be dedicated to the FCSA for operation and
maintenance. Upgrades to this facility to achieve the ultimate design capacity will be determined
through an agreement between the FCSA and the developer of the Shenandoah project. Projected
wastewater flow volumes for the proposed Crooked Run Regional Sewer Service Area Boundary
provide 487,200 gpd for the Shenandoah development; 45,000 gpd for the Double Tollgate
commercial area; 43,000 gpd for Sandy's Mobile Home Park; 25,000 gpd for the Camp 7 State
Correction Facility; 5,000 gpd to the Department of Games and Inland Fishery for concessions at
Lake Frederick; and a reserve capacity of 24,300 gpd.
The Frederick County Board of Supervisors will need to authorize the FCSA to provide regional
sewer service to the land in Frederick County which falls outside of the Shenandoah development;
as well as, extraterritorial land in Clarke County. Furthermore, the Clarke County Board of
Supervisors will need to authorize the FCSA to serve land within their locality should it be deemed
appropriate. The Comprehensive Plans and Programs Subcommittee (CPPS) will be the initial body
to begin this process. The CPPS will be asked to review this request to determine if the County's
Comprehensive Policy Plan should be amended to establish the Crooked Run Regional Sewer Service
Area as proposed by the applicant.
Please find included with this agenda item a memorandum from the FCSA to the Planning
Department dated January 23, 2001; a color map identifying the proposed Crooked Run Regional
Sewer Service Area with existing and proposed land uses, acreage totals, and the location of the
wastewater treatment facility; and information pertaining to the Crooked Run Wastewater
Reclamation Facility. Staff will provide additional information pertaining to this issue during the
CPPS meeting.

The attached exhibit was provided by Dogwood Development Group. It shows the proposed Crooked
Run Regional Sewer Service Area Boundary that includes the Shenandoah development.
Please review and comment as to conformance with the comprehensive plan. In drafting the agreement
between the Authority and developer, I want to ensure the Authority only agrees to provide service
within the area permitted by the County.

Wastewater Reclamation Facility
Concept Summary
The Crooked Run Wastewater Reclamation Reclamation Facility is intended to provide
wastewater treatment to the Shenandoah Community and to selected adjacent areas in
Frederick and Clarke Counties. The facility will discharge to Crooked Run, a tributary of
the North Fork of the Shenandoah River.
The treatment facilities will be located at the southern end of the Shenandoah
development, below the Lake Frederick Impoundment on the west side of Crooked Run.
Operation of the treatment plant will be governed by discharge permit number
VA0080080 issued by the Virginia Department of Environmental Quality under the
authority of the State Water Control Law and the Clean Water Act. The principal
administrative features of the permit are as follows:
Effective Date
Expiration Date
December 14, 1998
December 14, 2003
The qualitative limits for the permit are as follows:
Design Flow
250,000
GPD
CBOD5
7.5
mg/I
Suspended Solids
30
mg/I
Ammonia Nitrogen
4.1
mg/I as N
pH Range
6.5 to 9.5
Chlorine Concentration after Disinfection
1.0
mg/I
Effluent Chlorine Concentration, nondetectable
Dissolved Oxygen
7.1
mg/I
NOTES: CBOD and suspended solids limits are maximum monthly averages. Maximum
weekly averages are 1.5 times the monthly average values. The ammonia nitrogen
value is a maximum weekly average value. The dissolved oxygen limit is a minimum
value.
The permit does not place a limit on wastewater flow volume but it is indirectly
regulated by the imposition of mass limits on BODS, suspended solids, and ammonia
nitrogen.

Project Design Concept Summary
The proposed wastewater treatment facilities include the following unit processes:
Passive Screening (Screenings disposed in Frederick County Landfill)
Biological Stabilization (Phased Isolation Ditch variant of the Oxidation Ditch)
Disinfection (Ultraviolet Radiation)
Effluent Aeration (Cascade Aerator)
Aerobic Sludge Stabilization
Sludge Thickening (Thickened sludge to be transported to Parkins Mill WWTP)
The plant will be designed in such a manner that no single failure of a process component
in any unit process will result in a degradation of effluent quality. Facility reliability
features are as follows:
The passive screen will be a stainless steel 0.1 inch wedge wire unit. The _unit has no
moving parts. Screened solids will be collected in a roll away trash container,
The oxidation ditches will each have two sets of brush rotors for aeration. One set of
brush rotors in each ditch is an in place spare.
The ultraviolet disinfection unit will had a complete in place redundant unit. An additional
spare unit will be kept on site.
The treatment plant will probably be manned for two shifts a day seven days a week. The
treatment process will be continuously monitored and operated by a PLC based control
system that alternates wastewater flow and treatment patterns between two parallel
oxidation ditches based on wastewater flow and loading patterns. The control system can
remotely accessed for real time operational data and will include a remote alarm system.
A full scale standby power generator with automatic load transfer switch will be included
for process reliability.
Although the first phase of the treatment facilities are presently permitted on the basis of a
design flow of 250,000 GPD, the treatment equipment will be sized to treat a wastewater
flow of 375,000 GPD. The ultimate projected capacity of the Crooked Run Wastewater
Reclamation Reclamation Facility is 626,000 GPD. At that flow volume, additional
treatment unit processes such as clarification, chemical coagulation and filtration will be
required to meet the expected higher effluent requirements.

ITEM #2
LONG-RANGE PLANNING PROJECT PRIORITY RANKINGS
Each year, the Planning Departrnent conducts a retreat for the Board of Supervisors and Planning
Commission in February. The annual retreat affords staff the occasion to meet informally with both
bodies to provide educational opportunities and to conduct discussions regarding various issues
impacting the community. One item of discussion involves the Planning Department's annual work
program. To facilitate this discussion, staffprovides a list of potential planning projects, a summary
of each proposed project, and a table of the proposed projects to be ranked by each meeting
participant.
This year, staffhas separated planning projects into a long-range category and into a current planning
category. Staffwould like to review the results ofthe proposed long-range planning project priorities
with the CPPS. This will provide an opportunity for the CPPS to determine the next comprehensive
planning project and assist staff in the preparation of the process necessary to accomplish this task.
