MEMORANDL~
TO: Alan Ratliff, City Manager
FROM: Russell Doyle, City Engineer
RE: Culvert/Drainway Maintenance @ 632 Bethel School Road
RECOMMENDATION: City Council approval for expenditures for an
Engineering Analysis and remedial work that will be recommended by the
Engineering Analysis to remove silt and dirt from the culvert at subject
location. Total estimated funding is $5600.00.
BACKGROUND: Mr. Don Jones has landscaped his drainway easement a
number of times and it gets washed out at each heavy rain. He said if
some remedial action is not taken, he will start billing the City for
the remedial work. City staff has been working with Mr. Jones and
Public Works had arranged for the County to clean out the culvert and
dredge downstream, since the City does not have the proper equipment to
do this type of heavy work.
However, it was discussed and determined that an Engineering Analysis
should be done to provide just how far we should dredge downstream of
the culvert under Bethel School Road ; and how much, if any, regrading
would need to be done upstream along Mr. Jones' property to blend with
the slopes. This would ensure stable slopes after the work is
completed.
DISCUSSION: Although Mr. Jones feels the City should pay for the
regrading on his property, he says he is willin$ to do the resradin$
.relatin$ to an~ culvert cleani~$ work to be done by the Cit~ likewise,
Mr. Jones indicated to me that the neighbors will work with the City in
identifying their sprinkler systems, so that the sprinklers will not be
damaged. If this work proceeds, since the work to be done will be
recommended action from the Engineering Analysis, the Engineering
Department will coordinate the conduct of this work with Mr. Jones,
Public Works and the other property owners. (For More Information See
Attached Memo).
The estimated costs are:
Engineering Analysis $ 720.00
Cleaning Work 3500.00
Surveying 500.00
Contingencies 880.00
TOTAL ESTIMATED COSTS: $5600.00
* See Attached Work Order
SUMMARY: The work presented above is for providing the proper direction
to this maintenance operation in order to return this culvert to orig-
inally designed capacity; and to grade the drainway on both ends of the
culvert so that the flow of storm-water will occur in an efficient
manner, and that the slopes of the drainway remain stable.
