SUgJECT: Plans Submission For Water And Sewer System~ Lot 42, liarry R. ~oyle
Property, Section 30, T15N, R1W, S.P'. (Eagl~ River)
Uear /ir. Gardner:
Tile Greater Anci}8rage Area Borough i)epartment of Environ~mntal Quality has
received and reviewed tile proposal regarding the subject 'eater system and
subsequent sui)divlding ef the property. We will .divide tile entire submission
into tt;o parCs,. The first p~rt will be water and sewer syste~)t and ti~e second
part ~,dll be s~bdivision plat.
Nater a~d se~er system l'hg plans for tile ~er and sewer system
show adequate design al'Id supply in regards to the water system.
U~aever, ~,Je must have assuring, ce that there is ~io source of contamination
wit,)in t~e 40 foot radius of ghe well. As your plans saov~ tile southere
portion of the apartment house within thais 40 foot radius, we must have
adequate pleas showing ti)ere is no under~jround plu;.~lbing within this
portion of tile apartment hous'e.
Subdivision Plat It is our general guideline that lot size shall
be a minimum of 20,~300 square feet per single family residence when o~
o,~.. public ;~ater system. This ~later system by ~estgnation 'is semi-
public, class A. iio;-~ever, since the apart~mnt house is of several units
and located on a lot of only 22,000 square feet, there is not adequate
room on the nor&i~ end of the lot for se~l~r system replacemnt. In ~rder
go secure adequate room for sewer system replacmr~)nt, ~e would suggest
that some alternate design of the lot arranger, K;nt be im~de to allow tho
norti;ern portion of the proposed lot 42C to be larger for ad~;quate
server systole replace~.~nt.
At this point, I might suggest that you contact this office to discuss
this particular problem o~ lot size at further length. For unless the
o'~.mer, Nr. ttarry Doyle, owns more property in the i~I~..diate area it
appears that tim three lot split does not provide adequate room for
~,~aste disposal onllot 42C and that there is possibly no additional
room to increase the lot size. of the proposed subdivision.

i~ear ~,,r. Gardner:
I appreciai;e your early contact with this depart~Yen~ i~ regards to the previous
letter of Harch 13, 1974, a,d the anslvering of the questions as staled in this
letter. I appreciate all ~he inEomnation you provided on ~his, plus the
fact tiler it is obvious that Hr. 9o);!e does not hav~ additional proI~¢rty to
acid to lot 42C and that these Uiree buildings do exist on Ule property. It
is, therefore, obvious that simply spli~ting these lots into three parcet~
~dll neiUler improve or be detrtmel~tal to the situation that now exists.
Therefore, since ~he splitting of ibis property into throe lo~s is going
to present no potential health hazard and all tiwee properties are served
by an approved semipublic, class A ~-tell, this depar~raent finds tha~ Li~e
subject sub~n/ssion ~;~ets all requirements for widch vie are concerned.
Should you have any quesCions regarding this )~latter, please con,act
undersigned.

The existing system consists of 3 seperate septic tank and seepage
pits for 2-one fa~ily residences and one-6 unit, I bedroom apartment
building, located on Lot '42, Section 30, RIW, T15N, S.M., Alaska.
The intent ~s to subdiuide Lot 42 into Lots 42A, 42B, and 42C with
no expansion of the system.
The present system will serve 3 lots and wilt not be expanded.
The present and futu~e population to be served based on an average of
3.25 persons per single family residence and 2 persons per apartment.
unit = 18.5.
Permafrost is not known to be present in the area.
1. Existing system as stated in A.
2. Water source is a d~illed well on Lot 42C.
3. Domestic wastes only are treated by this system.
4. The estimated daily flow based on average flow of lO0 g.p.d, per
person is: Lot 42A - 32~ gallons
Lot 42B - 325 gallons
Lot 42C - 1200 gaZlons.
Estimated daily flow = 150% if average hourly flow and night
f~ow = 70% of auerage hourly flow. Maximu~ hourly flow =
170% of auerage ho~ly flow and minim~ flow = 30% of average
houmly fZow.
5. Industrial wastes are not and will not be treated in this system.
Not applicable.
EffZuent will not be discharged into a stream or body of water.
The disposal systems are located as shown on the plans.
Not applicable.
The system as it exists operates efficiently and trouble free making
a m)re elaborate system impractical.
Present system is recor~sended aa stated in J.
System as exists is GAAB approved.

' h WATER SYSTEM LOT 42
T15N, RIW, SM~ ALAS~
Water system for:
Lots 42A~ 42B, and 42C
Total Lots - 3
Lot ~-2C requires service for six (6) unit apartment building.
General
1. The system presently serves 2 single family residences situated
on lots 42A and 42B a~ 2 units of the six unit one bedroom
apartments on lot 42C.
2. This system ~ll also serve the remaining 4 apartments on 420
upon completion of same.
3. There will be no industrial activity which will affect the re-
quirements of this system.
4. The present water consv~nption based on an average of 3.25
persons per single family residence and 2 persons pe~ apartment
and an average consumption of lO0 g.p.d, per capita ~ lO0 (2 x
3.25 + 2 x 2) ~ 1050 per day or 0.73 g.p.m The future require-
ment with completion of the fo~~ units ~ 100 (2 x 3.25 + 16 x 2)
~ 1850 g.p.d, or 1.25 g.p.m.. The present peak demand for this
system is computed as follows:
For~Lots 42A and 42B:
l. Bathroom group with flush tank
Kitchen sink
3. Laundry tray
Total supply fixture units = 22
For Lot 42C:
1. Bathroom group with flush tank
2. Kitchen sink
Total supply fixture units = 12
Total load for system at present ~ 3~
With this load the supply demand is equal to 22 g.p.~, for
approximately 20 minutes or 680 gallons.
The system at present contains one 50 gallon hydropneu~atic storage tank
and a submersible pu, mp with a rating of 1320 g.p.h, or 22 g.p.~.
2/3 effective capacity of storage tank ~ 33 gallons
33 + 22 x 20 ~ 473 gallons.
The futume demand will be satisfied by installing an 82 gallon hydro-
pneu~atie storage tank in each of the remaining four apartments upon
completion.
4(2/3 x 82) + 473 = 692 gallons.
The source of water for this system is a drilled water well
located as shown on the plans. The well is cased with a 6"
casing to a depth of 64' to prevent ground water contamination.
The top of the well casing extends 12~ above finished grade.
The top of the casing is sealed and tbs discharge is by a
pitless ad~pter located below grade.
6. The water from this well is tested y~rly for quality.
7. Permafrost is not known to be present in this area.
