Box 196650 Anchorage, AK 99519-6650 Re: Septic System Permit Lot lB, BIk 2, Hideaway Forest Subd. Dear Sirs, With the submittal of the attached design package and Permit Fee check in the amount of $320.00, the owners of the above noted lot, Mr. Floyd Bayless and Ms. Marlene Story request the granting of an on-site wastewater disposal permit for a two bedroom house. We have relied on and verified the percolation logs of the original engineer to investigate this lot. The percolation logs of Corwin & Associates were taken from DHHS files. Our percolation test 1 was a verification of the tests performed by Corwin & Associates. We note that the logs indicate substantially the same material at depth, a Sandy Gravel to Gravelly Sand with Silt. The water level observed by Corwin is somewhat lower than that recorded after 7 days in percolation Hole 1, but we note that a measurement made by Mr. Ban Belles and Ms. Susan Oswalt on 10/25/90 indicates the water level to be substantially the same as our observation in Hole 1. After presoaking both holes for the required period of 4 hrs., we perked the holes at 25 min./in. & 9.04 min./in, respectively. We have used the more conservative figure of 25 min./in, on which to base our design because of our confidence in our methodology and the somewhat silty nature of the soils. The oversized septic tank will provide added retention time of the wastewater, and enhance treatment. Should you have any questions or require additional information, please feel free to call or fax me at the numbers indicated below. Sincerely, ~.~_~t-Alaska Engineering Services Robert W. Wright, P.E. Telephone (907) 338-6230 · Fax (907) 337-5182 May 21, 1994 W.O. 94002 Site Narrative The following site narrative describes the probable impacts of an on-site wastewater disposal system for Lot lB, BIk. 2, Hideaway Forest Subd. The subject lot is located in Sec. 24, T12N, R3W, at 11561 Trails End Rd. The lot contains 1.1 acres more or less. Access to the lot is off Trails End Rd., to the lower portions of the lot. The lot is covered by willow and alder shrub, with few birch or spruce trees. Lot slope is generally at '13%, except for a benched portion in the middle of the east/west direction leveled for the system. The lot is bounded on three sides by developed lots, and on the west by Trails End Road. The design drawings indicate the surveyed separation distances between improvements on Lot lB and adjacent lots. All Municipal separation distances have been observed. All well separation distances have been maintained from all portions of the proposed wastewater disposal system. The closest well to this system is located on Lot lA, and is 105 ft. from any portion of the system. Wells to the east, south and west are a minimum of 255 ft. from any portion of the system. The wells to the east, north and south are all up-gradient of the proposed system. Wells to the west of the system are more than 150 ft. from any portion of the system, and are separated from any potential surface flow of septic effluent by the north/south roadway ditch on the east side of Trails End Rd. The well on Lot lB is located in the extreme northeast corner of the lot. As shown on the system design drawings, the well is separated from on-site wastewater disposal systems on other lots by a minimum of 160 ft. This well is up gradient of all on site septic systems except the one to the east on Lot 2. It is felt that since this system occupies a position somewhat to the north of the well, any septic effluent which escaped to the surface would flow down gradient to the north of this well. All lots directly adjacent to and therefore affected by the proposed system are developed. They presently have both wells and on-site wastewater disposal systems. The remaining portions of these lots, available for reserve area, are more than adequate should any of these systems fail, and require installation of new systems. Telephone (907) 330-6230 · Fax (907) 337-5182 W.o. 94oo2 Page 2 The site drainage for all lots on the east side of Trails End Rd., in the immediate area of Lot lB, is to the west. The general topography for all these lots is similar, having slopes of 10% to 15% toward the road. The east side of Trails End Rd. is bounded by a drainage ditch which flows to the north. All run-off from these lots accesses this ditch to be carried to Upper O'Malley Rd. On-site drainage for Lot lB is handle by drainage swales at the upper (east) end of the lot, which direct run-off to the south and then to the west to access the drainage ditch at the east side of Trails end Rd. This lot is not affected by run-off from adjacent lots to the north, south and west. Run-off from the east is directed to Trails End Rd. via swales. The installation of this on-site wastewater disposal system will not adversely affect any adjacent lots. Wright-Alaska Engineering Services Robert W. Wright, P.E.

The approved separation distance(s) are the absorption field to the surface water of 30 feet. This waiver approval applies to the existing septic system to surface water separation only. Any future upgrade to the septic system will require all separation distances be met or another approval from this department. Should the operation of the subject wastewater disposal system cause any contamination or degradation of the subject surface water, this waiver will become void. Sincerely, Daniel J.

Box 196650 Anchorage, AK 99519-6650 Re: Septic System Permit Lot lB, BIk 2, Hideaway Forest Subd. Dear Sirs, The following design package is being resubmitted after revision per comments on attached pink transmittal sheet. The system dimensions have been adjusted to conform to the maximum 15 ft. width for absorption beds per DHHS letter dated June 1, 1994. Per my telephone conversation with Mr. Dan Roth, the surface water originating at the east side of the existing building will be caught in a top inlet surface drainage structure and piped via 4" perforated drain pipe to the 12" ADS drain pipe installed by the owner along the south edge of the driveway. The cut-off drain will be installed in accordance with the attached sketch. The owner will install this cut-off subdrain line prior to beginning construction on the proposed septic system. In compliance with standard practices and our agreement, the owner will provide the Department with two hours notice for inspection of the catchment, ditching and piping prior to backfilling. As this drainage pipe is within 100 ft. of the proposed system, it ~s our understanding that a waiver from Field to Surface Water must be obtained. Attached is a check in the amount of $920.00 to cover the waiver fee. We are requesting an On-site Septic System permit be issued, conditional to the prior installation of the above noted subdrain. Should you have any questions or require additional information, please feel free to call or fax me at the numbers indicated below.

Dear Sirs, The following design package is being resubmitted after revision per comments on attached pink transmittal sheet. Per my conversation, this morning, with Mr. Dan Roth, I have revised the attached design to reflect the comments discussed. A catchment design is shown on Figure B, attached. Mr. Bayless will construct the catchment as shown, from materials he has on site. Please note that the pipe exiting the existing catchment is 6" to approximately the last 15 ft. of its length, where it is 12". Mr. Bayless indicates that the last 30_+ ft. are insulated with 4" of rigid Insulboard. We have enclosed a flow calculation indicating that the 6" plastic pipe is capable of handling up to 1.25 cfs (561 GPM). This capacity is more than adequate for the less than 5 GPM the pipe will carry during non runoff periods. Attached are copies of utility locations for Gas, Electric and Cable. None of these utilities are effected by the location of the subsurface drainline. The Electric and overhead Telephone utilities are more easily accessible due to the location of the driveway on this lot. I have visited this lot today, and noted that no water is flowing from the lot to the east. Flow from the east side of the house is less than 0.5 GPM.. I have spoken with Mr. Bayless concerning the importance of installing the drainage upgrades and new septic system to acceptable standards. Mr. Bayless has indicated that he is very aware of the significance of proper installation, and has assured me he will comply with all DHHS requirements.

Box 196650 Anchorage, AK 99519-6650 Subject: Lot 1 B, BIk 2, Hideaway Forest Dear Ms. Oswalt, First let me apologize for the delay in getting this letter to you. RECEIVFD - SEP 13 1991 Municipality of Auci~ora e Capt. Health & Human Ser~/g~ces This letter is confirmation of the sewer and water disconnect on Lot 1 B, BIk 2, Hideaway Forest. On August 17, 1991 the sewer line connecting the existing structure to the septic tank was disconnected at the septic tank and plugged on both sides of the disconnect (see photos 1,2, 3, & 4). As well, the water supply line between the existing structure and water well was disconnected inside the structure from the water distributiOn system (see photos 5&6). At this time I'd like to inform you that the seep pit located 80 feet east of my well on Lot 2, BIk 2, Hideaway Forest has been abandon as outlined in my August 12, 1991 letter (see photos 7, 8, 9, 10, 11 & 12). I stated in my August 12, 1991 letter to your office that I would submit a septic redesign to your office by October 1, 1991. I would like to revise that date to October 31, 1991 due to other unforeseen problems not associated to this project. Should you have any questions or comments, please feel free to contact me. Sincerely, Floyd Bayless Owner cc: Carey Meyer, P.E. Floyd Bayless 1§69 I Street Anchorage, AK 99501 August 12, 1991 Susan Oswalt Municipality of Anchorage Department of Health and Human Services 825 L Street P.O. Box 196650 Anchorage, AK 99519-6650 Subject: Lot lB, BIk 2, Hideaway Forest Dear Ms. Oswalt, This letter is confirmation of our meeting August 9, 1991. RECEIVED AUG 1 2 1991 Municipality of Anchorage Dept, Health & Human Sery_ice8. It is understood that existing perk tests will be utilized in the redesign unless a portion of the redesigned system falls outside of the existing perk tests' 30 foot radius. Should this occur additional tests will be conducted where necessary. Concerning the existing outhouse seep pit located 80 feet east of my well on Lot 2, BIk 2, Hideaway Forest, it is my understanding that the seep pit must be properly abandoned in order to utilize my well. To properly abandon the seep pit it must be treated with chlorinated lime and Clorex, then backfilled. This will be accomplished and certified by an engineer no later than August 31, 1991 At which time it is understood that can utilize my well after the installation of an approved sewer system. Discussed was the possible usage of the current well and sewer system. It is understood that neither system can be used until approved by your office and that until such approval the existing structure cannot be used as living quarters. To assure your office that neither system is utilized, the sewer line connecting the structure to the septic tank will be disconnected, plugged and backfilled at the septic tank. Reconnection of the line to the septic tank will not take place until Spring 1992 when the tank is relocated to an approved location. As for the well system, the main supply line shall be disconnected inside the structure from the water distribution system. Both disconnects shall be accomplished no later than August 19, 1991. As well, a letter from the engineer certifying that the disconnects have been accomplished as outlined will be sent to your office no later than August 23, 1991. As discussed I will retain the services of Carey Meyer P.E. to redesign the newly installed sewer system on my lot and submit the redesign to your office by October 1, 1991. As stated in our meeting, your office has unlimited access to Lot 1 B, BIk 2, Hideaway Forest at any time to verify that neither the well nor sewer system are being utilized and that the existing structure is not being used as living quarters. Please contact me at 279-0543 or 272-8619 should you want access into the structure at any time. In addition I will take this opportunity to inform you that work will be in progress through out the forth coming fall and winter to upgrade the condition of the existing structure. As well, for the purpose of security against vandalism, all window areas will be covered with plywood by October 31, 1991. Should you have any questions or comments, please feel free to contact me.

[~anager ~n-site Services JW/ljm:200 enc: Copy of Permit "Kids Are Our Future" ~WATER AND WASTEWATER NARRATIVE FOR LOT lB, BLOCK 2, HIDEAWAY FOREST SUBD. The location of the well and wastewater disposal system on the subject property should have no negative affects to the adjacent properties or the environment for the following reasons: WELLS The adjoining wells on Lots iA and Lot 2, Block 2, Hideaway Forest and the on Lot 1, Block 1, Sunny Subd. are properly separated from the planned wastewater extension by at least 100 ft. and the existing well is located such that there will be no negative impacts to neighboring properties. WASTEWATER SYSTEM The wastewater system proposed for this property has been located so that there will be no effects to any surrounding properties. All setback distances have been satisfied as required. Further the soils are of such a nature that treatment will be assured over a long term period. The wastewater system is also located so as to prevent any contamination of the surrounding area. RESERVED SPACE The wastewater system on this property has no effect in taking away reserve area set aside on other adjacent lots and there is adequate reserve space on this lot lot for future replacement. SURFACE AND SUBSURFACE DRAINAGE The wastewater system will have no impact to surface water drainage due to the location and the fact that the contours will remain unchanged. Subsurface drainage will be unaffected since treatment of wastewater is assured before it reaches groundwater tables. The topography of the lot contains some areas of slope greater than 10 per cent, but the area selected to receive wastewater systems is fairly level with only minor sloping. JUSTIFICATION FOR BED SIZE since the proposed wastewater system requires 1,500 sq. ft., a 15 ft. wide bed would need to be 100 ft. long or a ratio of 1 to 7 for width to length. We believe that a better fit is to make the bed 24 ft. wide thus allowing a 62.5 ft. length or a ratio closer to 3 to 1 as is normally desired. During construction the contractor should ensure that excavation proceeds along the length of the bed to ensure no problems with not being able to reach with the backhoe and running equipment over the bed area during excavation. ~.,~__.. , ~~ :We o. ~ ~ J~ ;', / $~ ~ ~ ,,, .~ I ,_ I · ' · '-. ~ ~3 A] ], Dimensions ~d 5~cations Must Be Field Verified Prior To Construction · SEWER SYSTEM'LOCATION PLAN ~T J 6L~ J 8UBOIVI ~ION OEF~ARTMENT OF U{ -EALTH & H(JMAN 825 "'L" StCeet, Anchor~3ge.
