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, and the Sewage Handling and Disposal Regulations (12 VAC 5- 610 -10 et seq., the `Regulations "), (and local ordinances if the locality has authorized the local health department to accept private evaluations for compliance with 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 worldng in consultation with an AOSE for residential development. This subdivision was certified as being in compliance with the Board of Health's regulations by: Steven Gooch, AOSE #106. 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 is issued in reliance upon the certification that approved lots are suitable for "traditional systems," however actual system designs may be different at the time construction permits are issued. This subdivision approval does pertain to the requirements of local ordinances. Sincerely, /�V- 4�� Kelly L.

(give range if appropriate) Additional description of subdivision Overview of soils and geology (optional but encouraged) In order for VDH to process a subdivision application you must attach a plat of the property showing the location of the proposed onsite sewage disposal systems and the reserve absorption areas (if required) and the location of the water supply system on each lot, if applicable. Each plat or subsection of a subdivision shall be accompanied by specific soil information for each lot (absorption area and reserve area). If not provided by the local subdivision ordinance, the district or local health department may require the plat to show streets, utilities, storm drainage, water supplies, easements, lot lines, and original topographic contour lines by detail survey or other information as required. When the AOSE site evaluations are reviewed, the property lines, building location and the proposed well and sewage system sites must be clearly marked and the property sufficiently visible to see the topography, otherwise this application will be denied. I give permission to the Virginia Department of Health (VDH) to enter onto the property described during normal business horns for the purpose of processing this application and to perform quality assurance checks of evaluations and designs certified by an Authorized Onsite Soil Evaluator (AOSE) or a Professional Engineer (PE) as necessary until the sewage disposal ssal system has been constucted and approved. ` Signature of owner /Agent Date Commonwealth of Virginia Application for Subdivision Review (page 2 of 2 to be filled out by the county official requesting a VDH review) County Office initiating request Contact individual VDH Use Oaly Health Depanmenl IDp Due Dale Phone Local offices of the Virginia Department of Health may review subdivision applications for compliance with stale rules and regulations governing sewage treatment and dispersal and private watersupplies, compliance with Iota! ordinance governing sewage treatment and dispersal and private water supplies and potentially for compliance with other local ordinances.
