Health Dept. Re: LYN COTHARY 32224-51-02022 SWG2025-00071 The existing onsite sewage system(OSS)has experienced ongoing issues due to its age& installation on a steep bank with limited vertical separation(6 inches). The original System, permitted in 2000,includes a solids handling pump,septic tank,pump tank,and a pressurized 300 sq. ft. bed.Expanding or designing a new system in this same location is not suggested due to the cuts and large cut bank 15-20ft downslope. Given the challenging terrain,proximity to a shared well,and stream setbacks, relocating the drainfield is proposed to an area with more suitable soils(24-30"of loamy sands)and a gentler even slope.The new location offers consistent vertical separation(12"-18"),though less than state requirements.To compensate,the drainfield area will be expanded to 450sf(300sf required). Choosing trenches over a bed also provides increased sidewall infiltration area(780cf vs 360cf existing). Additionally,this relocation reduces the need for multiple stream crossings which exists on the current transport path. A gravity-fed system is recommended to avoid complications with power access and high costs associated with trenching or directional boring for a pump system.In addition,there is ample room downslope of the drainfield area to allow for horizontal treatment which is also an industry known alternative in reducing vertical treatment requirements. This proposal provides a cost-effective, environmentally responsible solution that improves the functionality of the OSS while addressing site-specific challenges and ensuring compliance with intent of regulatory requirements.

Installer must contact designer for final inspection of the installation prior to cover. All components,including tanks,lids, transport line,drainfield,and water lines must be open for inspection. A$350.00 fee will be charged for time involved with the inspection of the installation and creation of the record drawing. The designer reserves the right to charge additional fees if multiple visits are needed due to installation errors or inaccessible components. 2.This septic design must be installed by a certified installer with the local health department. All components shall be installed according to state,county,and manufacturer requirements. For Homeowner installs,the owner must get approval from the designer and local health department prior to attempting installation. 3. Designer is not a surveyor. Installer must familiarize themselves with property line locations prior to installation. Any confusion or conflicts with line locations should be reported to the property owner. A licensed surveyor may be necessary prior to installation to confirm all line locations. Any discrepancies found must be reported to the designer immediately. 4.Drainfield area may only be cleared by a licensed installer familiar with sensitive drainfield area preservation. The builder,lot developer,or property owner shall not clear the drainfield area. Any clearing required for drainfield installation shall not remove or disturb any top soil in Primary and Reserve areas. Removal or disturbance to drainfield soils could render design void. S.The property owner and installer are responsible for locating all underground utilities(ex.water,gas,electric)prior to installation. Any utility locations shown within design drawings are likely approximate and may not be exact. 6.All proposed tanks must be installed on original soils or compacted gravels. Extend all tank connection lines out onto original soil to avoid settling issues. Risers and lids must be brought to finished grade and left accessible for future operations and maintenance. Component manufacturers(ex.ATLI,Glendons,)may have other requirements not listed within this design. 7.All electrical wiring shall be done by a licensed electrician or homeowner(if allowed)and must be permitted through Labor andlndustries. Designer not responsible for electrical permitting or other electrical specific code requirements. S.The proposed septic system should be installed in dry weather conditions. Any failed attempts at installation during wet weather conditions may render this design void. 9. Maintain loft to waterlines with all septic components. If less than 30ft is required,sleeving in sch.40 pvc is required. If sewage transport lines and waterlines must cross,waterline must be 18"above sewage line with one of the lines sleeved in sch. 40 pvc loft in each direction of crossing. 10.This design may Include waiver applications with specific mitigation measures pertaining to installation,operation and maintenance of the proposed components. 11.Stormwater runoff,footing drains, roof drains must be diverted away from any septic system components. No curtain, foundation, perimeter drains shall be Installed 30t downslope and 10t upslope of drainfield areas. 12.This design is site specific and intended to meet state and county requirements that are related to the system components being proposed. Any placement of proposed buildings, proposed wells or other non-related items on these drawings may or may not meet other requirements. 13.All onste septic systems require regular maintenance to verify satisfactory operation. The system owner/operator is responsible for the continuous operation and maintenance of the system per WAC 246-272A. For operation and maintenance information,refer to Mason County Public Health Homeowner's Manual,which should be received after installation approval. 14.System owner should be cautious of landscaping around septic components. Root intrusion can cause premature failure of the drainfield area. In addition, bushes and trees should be kept away from lids and other septic maintenance points. 15. Changes made at time of installation may impact designer calculations,pump sizing,and compliance w/county and state requirements. Contact designer prior to install w/any proposed variations from design. Changes may result in additional fees and permitting.
