STATE OF MINNESOTA
COUNTY OF RAMSEY
CITY OF ARDEN HILLS
RESOLUTION NO. 83-25
RESOLUTION AUTHORIZING SANITARY SEWER CONNECTION TO
THE NEW BRIGHTON SANITARY SEWER SYSTEM
WHEREAS, the trunk sanitary sewer system of the City of
Arden Hills (the "City") between Interstate Highway No. 694 and
the south corporate limits of the City (i.e., District W) has
been determined in the Arden Hills Comprehensive Sewer Policy
Plan ("CSPP") to be inadequate, and
WHEREAS, such inadequacy in that portion of the City's
trunk sanitary sewer system which runs through District W is
because of sewage flows from District NC as indicated in the
CSPP, and
WHEREAS, sewage flows from District NC are pumped three
(3) times in the City before reaching the Metropolitan inter-
ceptor in Roseville, and
WHEREAS, the developable area of District NC is approxi-
mately 1,100 acres, the ultimate average daily flow through
District NC is estimated to be 0.793 M.G.D. (i.e., 793,000
gallons per day), and the estimated peak flow is 4.1 cubic feet
per second, (based on a 3.3 peak flow,factor), and
WHEREAS, the projected flows from District NC are as
follows:
Population
.!.!.!.!: Equivalent Average Flow M.G.D. Peak Flow C.F.S.
1980 ,2844 0.284 1.58
1985 5033 0.503 2.80
1990 5749 0.575 3.20, and
WHEREAS, it is anticipated that trunk sanitary sewer
capacities in District W will have to be increased by 1984 if
District NC continues to flow into District W, and
WHEREAS, a gravity sanitary sewer diverting sewage flows
from District NC to New Brighton would eliminate the need for
Sewer Plumping Station No. 10 in the City and the need for further
pumping of sewage from District W, resulting in a saving of elec-
trical energy and other operation and maintenance costs, and
WHEREAS, in the City's report entitled "Proposed New
Brighton Sanitary Sewer Connection", dated August 18, 1981, a
copy of which is attached hereto, it was shown that Plan B--the
plan therein which proposed the construction of a gravity sewer
to New Brighton--provided a long-term savings to the City of
approximately $325,000.00, and
WHEREAS, the City'e Council approved Plan B at its meeting
on August 31, 1981, and
WHEREAS, the City's Sewage Plumping Station No.2 in
District W will have to be rebuilt by 1983 if the projected flows
from District NC shown above occur, and
" . '"
.
WHEREAS, the Metropolitan Waste Contrql Commission (the
"MWCC") has stated that it supports the joint use of inplace
sanitary sewer facilities and has determined ia proposed diversion
of sanitary sewers from the City's District ~C through New
Brighton will not overload the present Metro~olitan interceptor
I
or have an adverse impact on the Metropolitan Wastewater Treat-
I
ment plant, and i
i
I
WHEREAS, the City believes the existirlg 42 inch trunk
I
sewer in New Brighton and the extension thereof to the City's
corporate limits meets the criteria set fortH by the Metropolitan
Council and may qualify as a Metropolitan in~ercePtor sewer, and
WHEREAS, the City has been advised by irepresentatives of
New Brighton that excess capacity amounting to four (4) cubic
feet per second is available in New Brighton's 42 inch trunk
sanitary sewer, and
WHEREAS, the City of New Brighton hes indicated it would
make the aforesaid excees capacity available to the City,
