The steepest slope was measured downslope of the constructed trench & the replacement trench. Analysis was conducted in accordance with the 4/17/04 guidance by lames Cross, PE. A profile was drawn with the existing ground slope, the 25% slope line and a line intersecting a point 2.5' above the system extended to the existing ground at a 35' distance. The Tablelands, B4 L7: The existing ground dips over 25% at a distance of 15'to 29' from the replacement trench. The overall slope stays above the 25% line. The slope of the line 2.5' above the system is @17%. The Tablelands, B4 L12: The existing ground dips over 25% at a distance of 25' from the replacement trench. The overall slope dips below the 25% line at a distance of 30' from the replacement trench. The slope of the line 2.5' above the system is @ 21%. The Tablelands, B5 LI: The existing ground dips over 25% at a distance of 22' from the constructed trench. At this distance a cut -bank is present. This cut -bank requires grading to less than a 25% slope. Spinell Homes Inc. requests that a conditional approval be granted in order for the work to be completed next construction season.

The soil test was good. Groundwater was monitored during the high water month of May and is not present. A conservative design has been completed, similar to Block 4, Lot 11. The neighboring lots are mostly developed. This site should not negatively impact any of the other area lots. The lot slope is relatively flat and drops off in the rear of the lot. Please review the wastewater system design for the single family home. I have included design plans & specs, design guidelines, & soil tests. If there is need for additional information or clarification please give me a call. Sincerely, Steve Eng, PE, I'll Design Enclosures bNEERINGI Tablelands S/D, Lot 12, Block 4 SPECIFICATIONS & DESIGN GUIDELINES Wastewater System Sizing: This is a new 4 -bedroom, single family home. Most of the neighboring lots are developed. Groundwater was monitored during the high time of the year and was present at 11' at the septic system site. The system was redesigned & elevated to a 6' depth. A conventional septic system is designed similar to the design on lot 11, Block 4. This lot is over 1 acre in size and no adverse impacts are expected from development. The neighboring lots are similar. The lots are served by a public water system. No conflicts to the other lots will take place by this septic system construction. The easements are located on the drawing and are not encroached upon. Soil tests revealed sandy soil with low silt. An application rate of 1 GPD/FV with 0.5 reduction factor for utilizing a 5' wide trench. Trench Length = 600 FT=/5'x .5 reduction factor = 60'; 1 line @ 60'. No bedrock was encountered. Specification Requirements: All components and work must comply with the Municipality of Anchorage Specifications (AMC) & State of Alaska Drinking Water Regulations and Wastewater Regulations. • Two compartment, 1250 gallon septic tank. Watertight couplings on inlet & outlet. • 5' minimum between the tank and bed. 10' to property lines. • 3' of cover or insulation is required for trench; an equivalent of 1" insulation for each foot soil cover. • Tank & solid pipe must be set on well compacted, stable soil. • 4 inch diameter cleanouts with airtight caps are required V to 4' from foundation wall, prior to any 90 degree bend in 4 inch line, in each tank compartment, and two adjacent opposing cleanouts between the tank and the absorption field, not more than 10' from the tank positioned to provide cleanout access towards the tank and towards the absorption field. • All cleanouts must extend to at least ground level. • In solid pipe runs, ASTM D-3034 may be used in lieu of cast iron. • Trench to be placed level, minimum of 4' to groundwater, 6' to bedrock from drain -rock. • Drain rock to be 1/2 inch to 2'/z inch screened. Drain rock to be distributed uniformly throughout the trench. • Perforated pipe to be installed level with perforations down. • Silt barrier (filter fabric) to be installed above the drain rock. • Smeared trench sides must be raked or scarified before drain rock placement. • Backfill over drain rock must not be less than 36". • The finish grade must be mounded to promote drainage over the trench. • Insulation must be placed over any pipe installed under driveways or parking areas. • Approved pipe materials include cast iron, PVC ASTM D3034, PVC ASTM F789, ABS ASTM D2661, • Sewer Service Line is minimum 2% slope. • If the slope exceeds 25% within 50' of trenches, regrade to maintain it less than 25%. • Septic Tank to be pumped every two years or when required. • Insulation board to be extruded direct burial polystyrene (Dow Styrofoam HI or equal) N\ kkf l� o a 0 E w N J (U ~ Z N O J (n E o L »� U w v D W <w S c •E U N Q LL F 0 a) E 3 u >- 3 CL . u CD M a� 'E ' W 7 W��'-'W N N > Q_ _ CL C7 C3 O v' J W'"' w GO W 0 .

STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines for this application, shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is(are)in compliance with all applicable Municipal and State codes, ordinances,and regulations in effect at the time of installation. In conducting an adequacy test,I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations.The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition,ground water levels that may fluctuate during the year,and the water usage of the family being served by the system.These conditions are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system,nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system.The content of this report is for the sole benefit of the owner listed above.

Box 196650 Anchorage, Alaska 99519 Subject: The Tablelands B L12 Number of Bedroom Justification I am writing to request the Certificate of Onsite System Approval be issued for this property.The system was installed for a four bedroom house, but a five bedroom house was constructed.This system was installed in 2006 and has operated as a five bedroom house for 12 years.The system should be approved for the following reasons: • The system has a proven track record of operating as a five bedroom system for over 12 years.The field was tested in April of 2018 and found to be approximately 60% used and was able to absorb greater than 750 gallons in four hours. • The system is oversized for a four bedroom system, it is actually sized for about 4.5 bedrooms. • The system is installed in sandy soils with some gravel, having a percolation rate of 4 mpi. • The house was constructed in 2006 using modern low-flow fixtures that reduce the water usage from the traditional 75 gpd/p to approximately 48 gpd/p (based on AWWU flow measurements) • The design criteria assumes that there will be two people per bedroom.That is an out of date statistic. The typical house five bedroom house has three to five people living in it. Bedrooms do not produce water, but people do. • When the system does eventually fail (extrapolating the life out from its current condition,the system has another ten to 12 years of life left in it) a new five bedroom system will be installed using the appropriate sized tank and drain field. Based on the above, the system is capable to safely dispose of the wastewater generated from this house. And not cause a health concern for this or the other surrounding properties.
