RE: Geotechnical Evaluation of On-Site Septic System
10670 E State Route 106,Union,Washington.
To Whom It May Concern,
Envirotech Engineering(Envirmech)completed a site visit on September 9, 2024 to the property in order
to observe surface and subsurface conditions. This geotechnical evaluation addresses the recently
constructed on-site septic system with relation to landslide hazards on and near the property. Information
collected from site observations and field testing was completed by Michael Staten with Envirotech. It is
our understanding that the septic is a standard pressurized system.
Subsurface conditions were visually classified as silty sand with gravel(SM).The septic drainfield area is
moderately to steep sloping straddling a ridge formation.
It is our opinion that the drainfield placement on the ridge where the subsoils are relatively dry and
protected from excess groundwater, the on-site septic system will not influence the critical slopes.
However,we recommend that the effluent dosage should be increased to at least 12 doses per day in order
to minimize each saturation.
If you have any questions or need any further assistance,please contact Michael Staten at 360-275-9374.
Sincerely,
Envirotech Engineering
