General Installation & System Notes 1. 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. 5. 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.ATU, 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 and Industries. Designer not responsible for electrical permitting or other electrical specific code requirements. 8.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 1 Oft to waterlines with all septic components&lines, unless approval within design/permit provides a reduced setback. Additional sleeving & install details may apply on reduced setbacks granted. 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 30ft downslope and 1 Oft upslope of drainfield areas. 12. Field staking and measurements taken are approximate. Installer may need to re-stake/layout drainfield laterals/beds prior to installation, level w/contours using a laser level in order to maintain the approved depth of excavation. Contact designer w/any problems related to drainfield layout prior to attempting installation. 13.All onsite 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 design prior to install w/any proposed variations from design. Changes may result in additional fees& permitting. 16. 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. p ® CUSTOMER:ZANE VANDERWAL _ PARCEL: 42125 - 76 - 90043 JUL 10 2026 SITE:60 E LEXINGTON PL r., 510393 Nj ALPINE SEPTIC MASON COUNTY ENVIRONMENTAL H� 1 DESIGN- y' L 2 ALEX L.PAYL'SE`�3 ALEX L PAYSSE,DESIGNER SHEET: NOTES SCALE: NA RET LICENSED DESIGNER 3089 E MASON BENSON RD GRAPE VIEW WA 98546 I I I EXPIRES 360-507-1546 0 0.5 1 2.
