CITY OF EDEN PRAIRIE
HENNEPIN COUNTY , MINNESOTA
RESOLUTION NO. 79-90
RESOLUTION REQUESTING Ni4CC
APPROVAL OF INSIDE DROP
CONNECTION TO INTERCEPTOR
SEWER. I . C. 51-332
WHEREAS , the City of Eden Prairie desires to connect an 8"
lateral sewer to the existing MWCC interceptor sewer• manhole at Co.- -
Rd . 60/I-494 arrd ,
WHEREAS , the MWCC staff has denied permission for connection
to said sewer manhole with an inside drop 'structure , stating that it
is the policy of the MWCC to prohibit the use of inside drop connections ,
and ,
WHEREAS , the City Engineer reports the following extenuating
circumstances in this case which would warrant a variance from the stated
MWCC policy to prohibit the use of inside drop CDnnections :
1 . Because of the high water table and poor soil conditions
in the vicinity of the connections, an outside drop
structure would cost an additional $15,520 in construction
costs over and above an inside drop as per the attached
a` Change Order No. 1 , dated 4/9/79.
2. Extensive trench excavation and dewatering would be nec-
essary to complete an outside drop connection . The present
water table is 15 ' above the bottom of the interceptor
sewer and it is possible that the contractor' s excavating
and dewatering operations could endanger the stability of
the interceptor manhole and also adversely affect the
water level and habitat in the large marsh area adjacent
to Bryant Lake which is public waters .
3. Upon review of the existing and future land use in this area
it is evident that there will be no additional lateral con-
nections between the manhole and 3, 000 feet to the north.
One inside drop structure, in lieu of no connections for
3, 000 feet, appears to be a reasonable situation ,
and ,
WHEREAS , per the attached liter of June 14 , 1978 the MWCC approved
a request by the City of Minnetonka for an inside drop connection to an exist-
ing MWCC interceptor manhole, contingent upon the understanding that the
City adopted a resolution stating their responsibility in any costs of opera-
tion and rnaintenance of the inside drop incurred by the Commission that would
be over and above the existance of an outside drop•
NOW, THEREFORE, BE IT RESOLVED BY THE EDEN PRAIRIE CITY COUNCIL
AS FOLLOWS:
A. That in view of the foregoing, the MWCC is herein respect-
ful ly requested to i ssue to the Ci ty a perm; t for an i nsi de
drop connection to the interceptor manhole at Co. Rd. 60/I-494..
B. The City herein accepts full responsibility for any cost of
operation and maintenance of the inside drop incurred by
the Commission that would be over and above the existance of
an outside drop .
C. A copy of this resolution shall be forwarded to the Minn.
Dept . of Natural Resources in concern for possible adverse
effects on Bryant Lake due to'dewatering and excavation
required for an outside drop.
