In short, we would be switching from CAT III to CAT II and would need a total FT of 150 FT (instead of 125 FT 2) for an application rating of 4 (<1 min/inch soil) for a 4 -bedroom home (600 FTz). We are proposing to increase the width of the existing bed by 1 foot. In summary, the proposed bed will be 6 feet wide instead of 5 feet wide. The contractor is proposing to use an Anchorage Tank 1500 -gallon steel STEP tank with a polyurethane coating. Please let me know if you have any questions or need additional information/design drawings. We are unaware of any adverse impacts this installation or waivers would have on adjacent wells or septic systems. If you have any questions, please contact us at 337- 6179.

Per the request of the homeowner, he would like a 4-bedroom septic design with his home located between the two creeks (see attached 100 scale). As can be seen on the attached MOA wetlands map and the 100 Scale, there are "class A" wetlands on the property, as well as two creeks (surveyed in by Fred Walatka, PLS), limiting the location of the septic system. Due to these facts and the presence of high groundwater (see attached soil log), we are proposing CAT III Advanced treatment (Advantex). We are proposing to install a new 1500-gallon Advantex tank with Advantex components, one AX-20 Pod and a mounded five-wide type trench with a 4.5-foot MOA approved sand filter. Additionally, due to high groundwater, we are proposing to utilize Engineered Receiving Soil. We are proposing to excavate down to 3.5 feet (into the GP- GM material), import 4.5 feet of MOA approved sand, and construct the drainfield above grade. It should also be noted that MOA onsite employee Tim Ecklund and GEG employee David Garness met onsite on 6/13/2018 to discuss the proposed design. Tim Ecklund was in agreement with the proposed location and felt as though it would not pose a health/safety risk to install the trench as proposed. Comments regarding the design are summarized as follows: 1. SOILS: When excavating the percolation bench/testhole the ground was frozen to about 2.5+ feet and groundwater was at approximatley 3 feet. Due to the high groundwater, and frozen soil, a percolation test could not be performed (see attached soil log). However, a soil sample was pulled from the GP-GM material below the ML layer and submitted to Alaska Test Labs for sieve analysis (attached). As can be seen on the attached sieve analysis, the soil is classified as a GP-GM. It should be noted that during the excavation of the testhole, water was pouring into the testhole at a depth of approximately 3.5 feet, indicating a percolation rate of less than 1 minute/inch. Based upon this fact, we are proposing an application rating of 5 GPD/FT2 for a CAT III system. This application rating is used for percolation rates of up to 15 min/inch, which is conservative and reasonable for the application of this design. 3701 East Tudor Road, Suite 101 *Anchorage,Alaska 99507-1259 Phone: (907)337-6179*Fax: (907)338-3246*Website: www.garnessengineering.com Page 2 of 2 2. DRAINFIELD DESIGN: See attached design drawing for drainfield specifications. 3. SURFACE WATERS: As can be seen on the attached design drawings, there are creeks to the west and east. See the "Waiver" section below and the design drawings for more information. 4. TOPOGRAPHY: As can be seen on the attached design drawing, the topography around the proposed drainfield is less than 10%. 5. WAIVER: We are requesting several waivers for the subject property. Below is a list of the waiver request, followed by its justification: • Drainfield, Tank, and AX-20 pod to surface water from 50 feet to 35 feet • The use of Engineered Receiving Soil • Waive the requirement for a percolation test Justification for granting these waivers is as follows: • Due to the abundance of surface water on the property and the presence of Class A wetlands, there is minimal room to place an onsite septic system. We feel as though the proposed location maximizes the separation distances given the proposed home location. • We are proposing the use of CAT III advanced treatment. The effluent quality will be much greater than that of conventional treatment. • We are proposing to use a 4.5 foot sand filter, after passing through the sand filter, the effluent quality will be even greater than that of CAT III after passing through the sand filter. • The Advantex system will be remotely monitored. If the system were to go into "high-level" alarm, the service provider would be notified, and corrective action taken. • The area between the proposed drainfield and surface water is vegetated. • During the excavation of the testhole, the west creek did not appear to be flowing. We are unaware of any adverse impacts this installation or waivers would have on adjacent wells or septic systems. If you have any questions, please contact us at 337- 6179.

Recognizing soil conditions and accurately rating the absorption capacity of the soils is vital to the design of a good system. At least two prospective areas should be investigated. When conditions are suitable, a deep trench soil absorption system is recommended and should be used because they tend to out-perform other system types. The perimeter of each proposed absorption area should be temporarily marked using stakes and string line. Every effort should be made to keep heavy equipment and vehicular traffic outside of the marked areas to prevent compaction effects on the soil absorption characteristics. The following sizing information shows the specific data needed to find the recommended soil loading or application rate,in square feet of infiltrative area per bedroom. • GW (Well Graded Gravel with percolation rate faster than 1): A two (2) foot thick sand liner beneath the sewer rock is required. Use an application rate of 150 square feet per bedroom. • GW (Well Graded Gravel with percolation rate of 1 or slower):A sand liner beneath the sewer rock is not required. Use an application rate of 125 square feet per bedroom. • GP (Poorly Graded Gravel with percolation rate faster than 1): A two (2) foot thick sand liner beneath the sewer rock is required. Use an application rate of 150 square feet per bedroom. • GP (Poorly Graded Gravel with percolation rate of 1 or slower):A sand liner beneath the sewer rock is not required. Use an application rate of 125 square feet per bedroom. • SW (Well Graded Sand): Use an application rate of 150 square feet per bedroom. • SP (Poorly Graded Sand): Use an application rate of 150 square feet per bedroom. • GM (Silty Gravel),SM (Silty Sand),or ML(silt): Requires an engineer's soil log and percolation test. Sizing requirements are as follows: Percolation Rate (min/in) Application Rate for GM.SM or ML • Between 1 & 5 use an application rate of 125 square feet per bedroom • Between 6 & 15 use an application rate of 190 square feet per bedroom • Between 16&30 use an application rate of 250 square feet per bedroom • Between 31 & 60 use an application rate of 335 square feet per bedroom • Between 61 & 120 requires engineering plans and prior ADEC plan approval Above 120 is considered to be impermeable and is not suitable • CL or CH (clay),OL(organic silt or clay),PT(peat): Requires engineering plans and prior ADEC plan approval.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 05/09/25 MU NICIPALITY OF ANCHORAGE ADV AN CED WASTEWATER TREATMENT SYSTEM MAINTENANCE AND REPAIR AGREEMENT THIS MAINTENANCE AND REPAIR AGREEMENT, herein the "AGREEMENT" made and entered into as of this 14th Day of_A_p_ri_l _____ of20�, by and between _1_7_3_L_e_d_;_y_a_rd_, L_L_C ________ , herein the "OWNER," and the Municipality of Anchorage, herein the "MUNICIPALITY", in accordance with Anchorage Municipal Code (AMC) 15 .65 .365.
