We are submitting this design and permit application for the construction of a new septic system. The attached site plan identifies the location of the home and the proposed septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. Adjacent lots are served by a community water system. This lot will also be served by the community water system. The ground surface on the lot slopes moderately to the northwest. Ground contours are shown on the site plan showing the grade and direction of flow. Storm water drainage will not impact this septic system. The new beds will be constructed parallel to the slope as much as possible. The new septic system will be a minimum of 100' from all wells and surface water. The alternate site is located more than 10' from the primary site. The beds will be 3' from the west lot line at the closest point. Please refer to the attached test hole logs and plan and profile sheets for the septic design. If this design is followed,there will be no adverse impacts to adjacent properties. Sincerely, N..• 49 TH %\ It Michael E. Anderson, PE 714-4-a-d.

Box 196650 Anchorage, AK 99519-6650 Subject: Knik View Estates,Tract C—22351 Judd Drive Separation Distance Waiver Absorption Bed to Lot Line Dear On Site Services Engineer: A section of the proposed absorption bed on the subject lot must be placed at 3' from the westerly lot line due to the proximity of the proposed house on the lot and the presence of shallow groundwater. The majority of the bed system is more than 10' from the property line. Soil conditions at this location are composed of clean sand with silt with percolation rates under 1 minute per inch. Very little migration of effluent is anticipated. The adjacent lot is served by a community water system with no well on the lot. In addition, the septic system is more than 40' from the common lot line. We therefore request a waiver be issued allowing the bed to be 3' from the lot line at its closest point.

These are to be satisfactorily addressed prior to MOA approval: 1. Records indicate that there is (or was) a community well on this lot. Please address whether or not it is still there or confirm it has been properly decommissioned. 2. There is public water routing down Judd Drive. Please confirm that a well is desired. a) If well is desired, an additional $215 fee is required for the drainfield to lot line waiver request. b) If well is not desired, please remove references in narrative and on site plan. 3. Narrative states that adjacent lots are vacant. Most of the adjacent lots are developed. Please address. 4. If design switches to public water, note that the 10 ft separation between the water service line and drainfields shall be maintained (including proposed alternate drainfield). 5. Confirm a minimum 10 ft separation from the drainfields to any subsurface drains (i.e. foundation drains). 6. Site plan note for alternate drainfield is missing the drainfield width. Please address. 7. Address tank buoyancy. 8. Under"System Requirement" on the section drawing, please correct the tank size. 9. Please confirm on-center spacing of holes in distribution piping, called out on section drawing. 1. No well is currently in place on the lot and no evidence can be found of a well casing. 2. The water service line remains on the property. It is shown on the Site Plan. The developer intends to continue the use of this service. N well will be placed. 3. The narrative has been revised. 4. The note has been added. 5. The absorption beds are more than 10'from the foundation. At this time the developer is not contemplating footing drains. A note has be( added however requiring the 10' separation. 6. Corrected. 7. The highest water table noted is 6'. Calculations indicate the tank will not float. A note has been added however to anchor tank as required. 8. Corrected. 9. Corrected.
