April 21,2024 Gorst Solid Lane,LZC PO Box 727 Port Orchard,Washington 95366 RE: Geotechnical Evaluation of On-Site Septic System XXX E Mason Benson Road,Cr peview,Washington. Parcel 22110-34-90043 To Whom It May Concern, Envirmech Engineering (Envirotech)completed a site visit on April 17, 2024 in the property in order to observe surface and subsurface conditions. This georechnical evaluation addresses the proposed 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 Envimtech. Subsurface conditions were visually classified as a shallow 1.5-foot layer of silty sand with gravel (SM) overlying poorly graded sand with gravel (SP)to a depth of at least 6 feet. The septic drainfield area is flat to slightly sloping with steeper grades at least 50 feet beyond. Critical descending slopes exceeding 40% were observed on the property, downslope and away from the planned septic rank and drainfield areas. Based on our slope stability analysis, it is our opinion that the proposed septic system will not influence the nearby critical descending slopes exceeding 40%,provided that vegetation remains undisturbed on the critical slopes. Earth movement remains a potential within the critical sloping areas, but this feature is located outside the influence zone.The property my or may not experience shallow landslides.However, we believe that the proposed dminfield has a sufficient setback from the top of critical slope,and will not contribute to furore landslides. If you have any questions or need any further assistance,please contact Michael Staten a[360-275-9374. Sincerely, Envirotech Engineering 6l --'9 xasrrrrU� t' arzlrza Michael Staten,P.E.

Minimum of 2 required in each bed with bottom extending to the dminrock/native soil interface. Glue"T"to bottom so Observation Port cannot be easily removed from ground. Install removable cap on top of port at final grade level. 5. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 6. Install threaded clean-outs at the end of all laterals(cap must extend to within six inches of finished grade and be marked with locator tape or rebar). 7. Install audio/visual high water level alarm. Redundant off switch requited. S. Install 1/8"mesh non-corrosive pump screen(min. 12 sq. ft. surface area,not to interfere with controls or floats.) Or pump screen may be substituted with Bio-Tube in septic tank. Pull bio-tube every 6-12 months and flush back into tank 9. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 10.Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock. Install laterals to the manifold with the orifices at 12 o'clock,(do not glue), after pressure test and Environmental Health Dept. approval,rum orifices down(6 o'clock)and glue laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position in lieu of turning the orifices down to the 6 o'clock position 11.Filter fabric required over drain rock prior to back filling. If the drain rock extends above natural grade,run the filter fabric at least 2 inches down the trench wall. 12. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 13. Divert all storm water runoff away from on-site sewage system. 14.No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the dtainfield and reserve area 15.Have the septic tank and pump chamber pumped or inspected every 3 to 5 years. 16.No vehicular traffic over drainfield area 17.Inspect floats,clean filters, and test high water level alarm every 6-12 months as needed. IS.All materials and workmanship must meet County and State regulations. 19. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 20. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 21.All pressure systems with a pump chamber outlet higher than the drainfield must have a 1/8"hole drilled in the discharge pipe above the pump to prevent siphoning. 22. All transport lines under driveways or parking areas must be encased to prevent crushing. 23. Homeowner is responsible for all property lines.
