Box 196650 Anchorage, Alaska 99519-6650 Rcf: Well and Septic Design for the West 1/2, SW 1/4, SW 1/4, NW 1/4, Section 5, T14N, R2W To whom it may concern: The proposed 3 bedroom house will be served by a private well and septic system. Two test holes were excavated on the property. Comments regarding the proposed design are summarized as follows: 1. SOILS: Attached are the logs which shows the soil profile, and the percolation test results. The soils below the organic layers are a GW/SW material with some silt to a depth of 12 feet (bottom of both test holes). No groundwater was encountered during the excavation of the test holes. A percolation test was performed in each test hole between the depth of 4.0 feet to 4.5 feet, which indicated the rates to be 3.1 & 5 minute/inch. It is our opinion that due to the overall appearance of the soils, a application rate of 0.8 gallons/day/ft2 should be used. 2. TRENCH DESIGN: a. Percolation Rate: 3.1 & 5 minutes/inch b. Allowable Application Rate: 0.8 gallons/day/ft2 c. Number of Bedrooms: 3 d. Design Flow: 450 gallons per day e. Minimum Absorption Area: 563 ft2 f. Total Depth: 5 feet (max.) g. Effective Depth: 3 feet h. Width: 5 feet i. Reduction Factor: 0.58 i. Minimum Length: 66 feet long j Effective absorption area = 569 ft2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 4. TOPOGRAPHY: As can be seen fi'om the topography information on the attached design, there are no slope concerns. The trench is to be installed parallel to slope contours. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact me at 337-6179, or 244-9612. Thank you for your assistance. Sincerel~~ ~~arne's'~, ~P.E, M.S.

GENERAL: The scope of this project includes the installatAon of a 1000 gallon septic tank and a l~achfi~d trench to s~rve the proposed three bedroom residence located on the referenced property. Construction shall be in accordance with the approved site plan and d~sign drawings, MunicipaA p~rmit with any special provisions or conditions, and all applicable State and Municipal Wastewat~r Disposal Regulations. 3. The contractor shall be r~sponsible for obtaining any necessary underground ut~ty locates. U~ess specifically agreed otherwise, the property owner shall be responsible for final grading areas subsequently depressed from soil set~ng. On all leaehfi~ld mound systems, the property owner shall be r~sponsible for ensuring a satisfactory vegetation growth over the mounded ar~a. Contractors instal~ng wastewater disposal systems m~t be certified by the Municipal Health Department for system instal~tions. Owners instat~ing their own systems must also receive prior approval from the Municipal Health Department. SE~IC TANK INSTALLATION: I. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" ~anout~ for pumping 2. The septic tank shall be sufficientAy bedded to prevent s~ng or shifting of the tank· 3. A~ standpipes on the septic tank shat~ extend a minimum of 12 inches above final grade. 4. Septic t~nks instated with l~ss than 4' of cover shall be insutated. Page Two W~, SW~, SW~, NW~, Sec. September 7, 1994 5, T14N, RIW, S.M. A foundation cleanoat shall be installed one to four fe~t from the building foundation. In the line b~tween the tank and the leachfield there shall be two adjacent cleanouts (u~ss an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10' from the tank. The first cleanout, in line, shall be to clean toward the leachfi~ld. The second cleanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSO~F~'ION TRENCH/'~,AINFIEL~ INSTALLATION: Excavate the proposed trench to the d~mensions shown on the design. The bottom of the excavation sha2~ be within 2 inch~s of level. If the sidewalls of the excavation §ecome smeared, they must be raked or scratched (roughed-up) before gravel (sewer rock) placement. o Once the gravel is insta£1ed, the d~tribution pipe is to be installed lev~ with the perforations faced downward. Gravel is then to be placed over the distribution pipe to provide a minimum of 2 inch~s of cover over the pipe. A silt barrier must be installed b~tween the final grav~ layer and the native soil backfill. Ensure the silt barrier cover~ the en~re gravel surfac~ b~for~ p~ng backf~. Monitor tubes shat~ be of four (4) inch diameter and insta£1ed approximately in the locations shown on the d~sign. The portion of the monitoring tube extending through the gravel shall be p~rforatad from the bottom of the trench to the invert of the distribution pipe. Th~ is equivalent to the effective depth of the gravel as noted on the design. Backf~l over the final gravel layer must not be l~ss than twenty-fo~ (24) inches. Ins~ation must be installed when the backfill depth is l~ss than thirty-six (36) inch~s. The finch grade over the trench must be mounded to preve~ the formation of a depression after s~ng.

A permeable non~oxi~ silt barrier (Typar $401, Mirafi 140/N, or equa£) must be installed between the final leachfi~ld grav~ layer and the native soil backfill. All leachfi~d gravel (sewer rock) sh~2~ be 0.5"-2.5" screened gravel with l~ss than 3% passing the #200 sieve. When sand i~ b~ing used as a filter material, its gradation specifications mu~t conform to current M.O.A. or D.E.C. requirements. Typically there w~ll be a mi~um of three (3) inspections required during the installation of the wastewater dispos~ system. These inspections will occur as follows: I. The first inspection must be conduced after the excavation of ditches, pits, trench~s, or bed~ and before the installation of any grav~. A septic tank may be set in place, but may not be backfilled before t~s inspection. 2. The second inspection mast be conducted after the placement of the si~ barrier, grav~, distribution lines, standpipes, ~anoat~, and insulation, but before the placement of any other backfill.
