RE: Review of Proposed Subdivision Plat and attached Soils Information for Individual
Onsite Sewage Systems as part of a division of Tax Map 79 Parcel 17C located in
Albemarle County,Virginia.
Dear Ms.Yaniglos:
On January 1,2014,the County of Albemarle requested the Virginia Department of Health(via the Albemarle
County Health Department)review the proposed subdivision plat identified above.This letter is to inform you
that the above referenced subdivision plat is approved for individual Onsite Sewage Systems in
accordance with the provisions of the Code of Virginia,the Sewage Handling and Disposal Regulations,
and local ordinances.
This request for subdivision review was submitted pursuant to the provisions of§ 32.1-163.5 of the Code of
Virginia which requires the Health Department to accept private soil evaluations and designs from an
Authorized Onsite Soil Evaluator(AOSE)or a Professional Engineer working in consultation with an AOSE for
residential development. This subdivision was certified as being in compliance with the Board of Health's
Regulations by: Stephen P. Gooch; Onsite Soil Evaluator Number 1940001284. This subdivision
approval is issued in reliance upon that certification.
Pursuant to §360 of the Regulations this approval is not an assurance that Sewage Disposal System
Construction Permits will be issued for any lot in the subdivision identified above unless that lot is specifically
identified on the above referenced plat as having an approved site for an onsite sewage disposal system, and
unless all conditions and circumstances are present at the time of application for a permit as are present at the
time of this approval. This subdivision may contain lots that to do not have approved sites for onsite sewage
systems.
This subdivision approval does pertain to the requirements of local ordinances.
Sincerely,

designs and when applying for a certification letter or subdivision approval.

Width of trenches: 3' Center to center spacing: 10'
Reserve required? This is reserve_ Percent reserve area required: 100
Total width of absorption area required 43' Total trench bottom area provided: 1500
The required width is calculated by multiplying the center-to-center spacing by one less than the number
of trenches and adding I trench width plus any required reserve area. If the topography is not uniform
across the length of the site the trenches will need to flare apart on one end to maintain contour. When
this occurs it is necessary to use a center-to-center spacing that accounts for the flair or the installer will
not be able to fit the system within the approved area. It is perfectly acceptable to have more area
available,especially up and down the slope,than is required.
