Program

The first review of our special use permit application resulted in the following three major
questions/issues to be addressed.
Do the internal changes to the existing residential structures on TMP 06000-00-00-057FO
qualify as a change of occupancy under the Virginia State Building Code? Staff from
Albemarle County Fire & Rescue and the Inspections Division have indicated that one
structure may change from a single family residential occupancy to a different occupancy
classification. Under the Building Code, a sprinkler system and other life safety features may
need to be installed.
See attached letter from Bowie Gridley Architects. The smaller residence on the property will
have no change in use. The larger structure will have a change in use from R-1 to R-3.
Determination of building code requirements will be thoroughly investigated prior to the
building permit application and the School will comply with the required provisions.
Also attached is a working floor plan sketch and the current floor plan. This will be used as a
starting point for the full design of the space. The School is in the process of hiring a design
builder to assist with the project. More specific building code requirements will be address
through this process.
Albemarle County Fire & Rescue has indicated that the existing gravel driveway may need to
be upgraded in order to provide adequate emergency vehicle access to TMP 06000-00-00-
057F0. This cannot be determined until the applicant submits an evaluation of the existing
buildings to the County for review.
Met with Shawn Maddox with Fire & Rescue on site February 15. Since the building
classification has been determined to be R-3, a code compliant sprinkler system and fire
monitoring system have been requested. During the building permit process, we will have a
site plan drawn for the road and driveways and work with Mr. Maddox to determine what
improvements need to be made to ensure a 16' wide road and a 25' ft turnaround area for the
property.
The Virginia Department of Health requires a Capacity Assessment Report prepared by a licensed
professional engineer prior to recommending approval of the special use permit. The existing sewage
disposal system may not have the capacity to handle sewage from the number of residents that will
live In the structures on TMP 06000-00-00-057F0.
Attached is the Capacity Assessment Report from Old Dominion Engineering. The small residence is not
changing use and is not undergoing renovations. We are not planning on making any changes to the
water and septic at this property. The report indicates that the larger structure does not have an
adequate septic system and that connection to public services are recommended. We are currently
working with a civil engineer to develop a plan and cost estimate to connect to public water and sewer
for the large structure. It is anticipated that the connection will be made through the infrastructure at
our current School facility. During the building permit process, we will provide the necessary plans as
well as any additional required applications.

Re.: Faulconer Dr. Property - Use and Occupancy Classification
Dear Diane,
As requested, we have reviewed the "change of use" issue raised by staff in the County of
Albemarle report related to "SP201700029 St. Anne's Belfield Junior Residential Life
Program", dated February 2, 2018.
We believe that, if the he subject structures located at 790 Faulconer Dr. currently hold
Certificates of Occupancy classifying them as single family residences, the School's proposal
to convert one of these structures to a small residential facility for eight (8) students and two
(2) supervising faculty members would, in accordance with the Virginia Construction Code
(VCC), constitute a change in use. Chapter 2, Definitions of the VCC code states:
"CHANGE OF OCCUPANCY. A change in the use or occupancy of any building or structure
that would place the building or structure in a different division of the same group of
occupancies or in a different group of occupancies; or a change in the purpose or level of
activity within a building or structure that involves a change in application of the requirements
of this code."
The VCC references the International Building Code (IBC), which classifies Use and Occupancy
in Chapter 3. Based upon the defining characteristics of the various Residential Use Groups,
we would expect the School's proposal described above to be characterized by the IBC as an
R-3 Residential Use Group. Specifically, that the School's proposal represents a non -
transient, congregate living facility with 16 or fewer occupants.
Please note that once the School is ready to commence work on the design of the proposed
project, a thorough analysis of building code requirements will be necessary.
Please feel free to contact me with any questions that you may have.

Physical Address: 790 Falconer Drive Charlottesville, VA 22903
ATTN: VDH - Albemarle County
Assessment conducted by Old Dominion Engineering (ODE)
Facility Usage
Saint Anne's Belfield School (STAB) is converting the dwelling on 790 Falconer Drive
located on TM 60-57F (3.59 acres) into a 4 bedroom (double occupancy) Dorm with two
1 bedroom apartments. A second dwelling on the property shall remain and is served by
a separate septic system.
The facility is currently served by a conventional septic system and drainfield. No
records were located for the existing septic system. Portions of the system were
unearthed to determine the existing components.
New Dorm Septic System
• Septic Tank - 1000 Gallon Mid Seam
• Concrete D Box with 8 ports
• Drainfield Trenches - 8 trenches, 3 foot wide, 100 foot long, 24" deep (2400 sgft)
The existing system has some defects/issues including root intrusion into the main sewer
lateral between the septic and the house, the distribution box needs to be replaced, and it
appears that additional trenches were added to the system over the lifetime of the house.
The estimated pert rate of the dispersal horizon is estimated to be 90 mpi by examining
the soils in the existing dispersal area.
There are two wells on the property. It appears that one well is serving both houses.
This capacity assessment was done to determine if the current onsite wastewater and
treatment system can handle the dwelling usage as a dorm/apartment.

Conclusions
2/7/2018
The existing onsite wastewater systems will not be able to handle the anticipated
wastewater effluent strength and flows for the owners new intended usage as:
1. Dorm - The dorm would require septic system repairs, additional septic volume,
more dispersal area, and an identified reserve area.
Note 1 - Additional soil borings were done during the inspection and it was determined
that the available soils for drainfield expansion would require shallow installation and
would require additional treatment (TL3) and drip pressurized dispersal.
Note 2 - The main STAB campus is connected to the public sewer via a pump lift station.
It appears possible to connect both of these dwellings to the existing pump lift system.
Recommendations
The most cost effective and feasible solution for the septic of the dorm is to connect the
septic system to the main STAB pump station. ODE recommends utilizing the existing
Septic Tank and either connecting via a gravity or pump line to the existing STAB pump
lift station or supplemental lift station at the ball field.
The septic tank would need to be modified with 2' diameter riser and effluent filter.
Whether a gravity sewer or pump line would be required would be determined by the
route selected for the connecting piping from the septic tank to the pump lift station. It
would be prudent (and cost effective) to connect the other dwelling to a shared sewer
concurrently with the dorm.
