SEWER FACILITY LAYOUT Dear Roll: After our discussion in your office reference this subdivision last Friday, November 3, 1972, I made another inspection of the proposed subdivision with the owner, Mr. Woodland. .Mr. Woodland has commenced excavation and embankment on the pro- posed lots 6,7~8,& 9 to provide level building sites and to em- bank the area of lot 6. Prior to any embankment lot 6 was entirely unbuildable since the majority of its area was essentially at the water level of the lake. At this date there is approximately 5 foot of embankment over 50% of the lot. By the time this plat is heard Mr. Woodland plans on completing his acti'vities and the entire area of lot 6 will have from 5 to 10 feet of embankment thereby making it ~p~actical for a building site and "on site" waste disposal. The material in the vicinity of test holes 1,2,&3 have been ex- cavated so the information is not applicable. The visible cuts now adjacent to Glenn Highway show material ranging from 150 S.F. to 200 S.F. in classification. The seepage pits for the entire proposed subdivision have been placed to ~epre~ent the typical 175 S.F. to 200 S.F. except for lot 9 which utilizes 150 S.F. classification. Such spacing has necessitated relocation of lot lines on lots 1,2,3,4 & 5. If there are any questions please contact me at 279-6508. Thank you. Sincerely, R'o'n{~l~d L. Thiel, P,E. RONALD L. THIEL. A.P.C. CONSULTINg ENGINEER June 8, 519 WEST EIg TH AVENUE Mr. Robert C. Johnson Box 456 Eagle River, Alaska Re: Lake Ridg~T~e~_~_~_.Su~~ SEWER REPORT Dear Mr. Johnson: Pursuant to your request a cursory engineering report follow~hereinafter to satisfy the requirements of the Planning and Zoning Department of G.A.A.B. A visual inspection of the above referenced subdivision was conducted on June 5, 1971, for purposes of determining soils con- ditions for on-site sewage disposal systems. This subdivision is a portion of a larger subdivision platted prior to the construction of the new Glenn Highway. Eighteen of the proposed twenty-two lots physically border the new Glenn High- way which has exposed a cut bank up to flfty feet in height. This cut bank shows a continuous representation of the soils condition and enables a perfect determination of soils classification. The soils consist of gravel with about 10 percent silt con- tent and shows thin stratas of silt starting at twelve feet in depth. No obvious moisture seepage from the cut banks are visible. No percolation tests were run but through soils classification the material rates 2.5 gal./S.F./Day. An average lot Of this size and nature could expect one house with five persons in the family. Given typical conditions with an on-site water system the expected water consumption and wastes are assumed to be 100 gals. per person or a to~al waste load of 500 gals. for each dwelling. The recommended size of a seepage pit would be 6'x8'x8' Sincerely, RONALD L. THIEL, P.E. RLT:cw Engineering Geology B Mining · Geophysics . Groundwater . Petroleum July 21, 1972 Greater Anchorage Area Borough Department of Environmental Quality 3500 Tudor Anchorage, Alaska Re: Soils and Percolation Qualities of Lots 4, 5 & 6, Lake Ridge Terrace Subdivision in the Eagle River Area Gentlemen: Our firm performed a soils investigation of Lots 5 and 6, Lake Ridge Terrace Subdivision in the Eagle River Area for Mr. James Polyefko. The investigation was performed September 22, 1971. Mr. Polyefko recently informed us that the sewage disposal fa~cilities are actually situated between Lots 4 and 5. This situation has apparently caused a problem in view of Borough requirements for a soil test on the specific site. It is our opinion that the geologic conditions are homogeneous throughout the three lots since the subsurface materials are products of the same phase of glaciation. If this information could be used in place of another soil test it would save Mr. Polyefko the expense and inconvenience of digging up a newly seeded lawn. The soils on his property necessitate a seepage area of 185 square feet per bedroom. HJM:d Respectfully submitted, ALASKA GEOLOGICAL CONSULTANTS Harold J.

Chief Sanitarian Lakeridge Terrace Subdivision Sewer Facility Layout hie have received soils information, which is adequate, and lay- out of on-site sewer systems on the proposed lots for this subdivision. The proposed layout of well and sewer locations on this subdivision is such that we must ask for a final topography mall on t}~is property prior to our approval. It is very likely thaC based on topography, rather than individual wel)s on this property, we will be asking /~he developer to provide a community water system. The reason for this is that it appears that sewer systems will be at a higher elevation than the wells are on this proposed property. bb Plat Status: Final uREATER ANCHORAGE AREA BOROUGH t04 I~st Northern Lights Bou]evo.rd Anchorage, Alaska 99S03 2387 Date: May 19, 1971 BOROUC~: Engineer Public Works Department Sand Lake Fire Department School District Street Names Tax Assessor Alaska Department of Highways Alaska Railroad Anchorage Natural Gas Corp.

E., Program Manager, On-site Services Department of Health and Human Services ~,TH- SUBJECT: S-2387A: Lake Ridge Terrace, Lot 4 Block 7A Amended Comments u The original plat had the following note: ?This subdivision at the time of filing is not served by public water and sewer facilities. No on-site water and/sewage disposal facilities may be constructed without prior approval of the Health Department." The additional note referring to Lot 4 "no dwelling unit shall be constructed or placed on this lot" served as aknowledgement that Lot 4 was not developable using on-site water and wastewater systems. The fact that previous on-site wastewater systems have failed on thi~ lot supports the fact that this lot should not have been developed. The Alaska Department of Environmental Conservation should not have issued a certificate to operate an on-site wastewater disposal system on the subject lot. It is our understanding that had the Alaska Department of Environmental Conservation been aware of the plat note the certificate to operate an on-site system would not have been issued, JS/ljm ~O'd q~lOl M~ICIP~IT¥ MEMOR ~t-lt" brand fax transmittel memo DATE TO: FROM: SUBJECT February l, 1994 Department of Economic Development a~d Planning Zoning and Platting John Smith, P.
