Creekview Estates Sewerline Construction
W.B. Johnson - letter dated 20 Oct 1988

Dear Mr. Ratliff,
Subsequent to the receipt of your letter (ref A), I received the
ref C letter from Peter Staks indicating that the protective wall
proposed by Creekview Estates will be approximately 30 feet long,
in liew of the 56 foot length stipulated in my approved drawing
(ref A). I have discussed this proposal with Russell Doyle and
conclude that the city has conceeded to the developer's wishes.
This is a serious error and doe~ NOT represent the best interests
of the city.
The act of installing the sewer line, piers and other construction
makes the developer totally responsible for the protection of the
creek bank, both in the area of the easement and on each side there-
of. This proposed fix, while protecting the sewer line and ease-
ment, also accelerates the natural erosion process upstream and
downstream of the proposed wall. This primarily the result of
the position of the wall segment in relation to the creek channel.
Specifically, the impact of the current is approximately 80 degrees
to the creek bank within the area extending from the sewer line 50
ft upstream. ~herefore, covering half of this bank area with a
concrete wall merely compounds the erosion of the unprotected area
adjacent to the wall. The proposed wall should be extended a min-
imum of 20 ft further upstream and an additional 5 ft. downstream,
to comprise a wall 56 feet minimum in length. Only a longer wall
will provide the necessary protection without exposing the city to
future liability for repair &/or extention of the wall to the proper
length.
The city staff has apparently adopted a "wait and see" attitude
rather than insisting on a proper permanent solution. I strongly
recommend that you advise the staff of the consequences of approv-
ing the proposed fix stated in the reference C letter.
.Mr. A.D. Ratliff

I personally disavow all responsibility and/or liability associa-
ted with the proposed 30' long retaining wall. I also hereby
withdraw any approval, written or verbal, other that the approval
specified in my ref A letter.
Please note that I feel the developer is wholly responsible for
any accelerated erosion and /or other damage etc. caused as a
result of placing the sewer line in the bend of the creek. When
the city accepts title to this utility easement, all responsibility
shifts to the city. Therefore, any repair, rebuilding or extension
of the wall will be at city expense. Also, the repair of any dam-
age to property adjacent to the sewer line/ easement would be at
city expense. This exposure is NOT warranted.
We both recognize the consequences of the temporary fix being
proposed by the developer, however, I feel your staff does not
share this philosophy. I strongly recommend this fix be "done
right the first time", thus eliminating future problems for the
city.
Sincerely,
WBJ: cj
