Water Availability Study
Dear Mr. Cross:
I have recently completed a study of the lots surrounding the proposed The Villages Subdivision to
determine the depths and production rates of the wells and overall water availability and quality. Most of
the lots to the north and south of this subdivision are served by a community water system and only the
Paradise Valley Subdivision to the northeast and the lots immediately to the west were available for
study.
The results of the study indicate the four wells reviewed were between 266' and 330' deep aud produce
water at rates fi'om 2 gallons per minute to over 15 gallons per minute. Production rates were based on
the information submitted by the well driller and are probably higher than the actual production rates.
No recent information was available concerning flow tests or water quality. A water quality test
performed in 1997 on Lot 3, Block 2, Paradise Valley indicated no coliform or other bacteria and only a
trace of nitrate content. The water in the ama appears to be free of bacteria or unacceptable levels of
nitrate content.
Tract 7A of The Villages Subdivision is the subject pamel for this subdivision. It will be split in tlu'ee
parts to form Lots 1, 2 aud 3, The Villages Subdivision. From information obtained fi'om surrouuding
wells we can conclude the wells will be in excess of 300' deep and will produce between 2 and 5 gallons
of water per minute. We cannot, however, guarantee these depths or production rates.
Backup documentation concerning the wells ia the area am included for your review.
know if you have any questions.
Sincerely,
Michael E. Anderson, P.E.

The Villages Subdivisiou - Lots 1,2 and 3
S-10215
Septic System Reserve Areas
MAY 28 1998
Muuie~pality of Anchorage
Dept. Health & Human Servlee~
Dear Mr. Cross:
The owners of Tract 7A, Tile Villages Subdivisiou intend to subdivide the tract iuto 3 lots. Each lot will be in
excess of 2 acres in surface ama. The attached site plan deliueates tile throe lots and shows the location of the
septic system reserve areas. These areas ollcompass 12,000 square feet ill area based on percolation rates of 5
minutes to 12 nfinutes per inch which were achieved ou soils eucountered ill the testholes on the lots.
A subsurface soils exploratiou study was completed oil tile property in December of 1995. Additional testholes
were recently placed to augmeut previous results and verify that soils were suitable for onsite septic system
placement. In addition, water monitoriug was completed over the April-May period to determine whether
groundwater would impact septic system coustruction. No water was noted in any of the monitor tubes during
this period.
Soils on the tract are fairly uniform and consist of an organic layer on tile top 1' to 2'. This layer is underlain by
well graded gravels and sands or silty gravels aud sands. All testholes on the property revealed virtually the same
material. Gradations were run on samples fi'om Testholes I, 2, 3 and 4. Iu all cases more than 80% of the
sample passed the No. 4 Sieve and 12% to 20% passed the No. 200 Sieve. The percolation rate achieved on this
material was 5 minutes per inch. Testholes recently placed revealed the same materials with a slightly slower
percolation rate of 12 ~ninutes per iuch.
Tile surface of tile property slopes primarily from east to west with some cross sloping fi'om north to south. The
drainage pattern appears to be iu a northeast to southwest direction at grades as steep as 12%. No areas were
found ill excess of 25% which would limit the location of tile septic systems.
It is our conclusion based ell tile results achieved fi'Olll the subsurface soils investigation and the water
monitoring throngh the wettest period of the year that septic systems can be snccessfully placed on this property
at the locations identified. Please review this data and advise if you bare further questions.
Sincerely,
Michael E. Anderson, P.E.

Re: Tract 7A The Villages; Test Hole Results
Section 15 TllN R3W S,M.
Dear David Tisch:
Attached are test hole logs and sieve analyses for test holes on
the referenced property. Materials found in the four tesf ho]es -:-~e a
visually similar sand and gravel mixture with a fair amoun~ of silt.
An informafional percolation test was run on Test Hole I~4~ and a rate
of appro×]mately five minutes per inch was observed. Because of the
percolation rste, a full specif~cat, ion test would reql]il;~ presoaking
the day before testing. This was not done due to time and ]~ght con-
straints. Perc rates between one and sixty minutes p~!- ]neb might be
expected on ail the test ho]es, The results of. this ]nv,~s[igation
indicate that Tract 7A contains soil suitable for onsife wastewater
d~sposa] systems. The test holes were sited to allow at least ]00 feet
setback from the surface water found during the prior s]t~ visit in
November.
Since this was a pre-purchase feasibility study, some steps were
taken to fry to accommodate future work that may be required to subdi-
vide the parcel. Although no water was found in any of the test holes,
a monifor tube was installed in each excavation. Also, the topsoil was
removed adjacent to each he]e to expose the mineral soil representa-
tive of fha so]l that was tested. Good luck.
