STORM DRAINAGE UTILITY
Wickstrom explained that the- only thing that was different from
what was presented last time is the schedule. We also have an IBC
recommendation. Since we are talking about drainage utility
changes; adjusting water rates and a three month meter reading
operation, it was suggested we address these as a package. If we
go with the drainage utility and do all these changes and then come
back in a couple of months and do the street utility, citizens will
be wondering what Is happening. By packaging all the changes at the
same time, we would be able to send out one letter to the
customers. Wickstrom continued that a public hearing is proposed
for the end of February or first of March. A Council workshop to
go over all these changes is proposed for January 14.
White indicated his understanding in what is being suggested to try
to package but stated that he has some real copggxns about the
total package. He recognized that this is a long term process but,
specifically, what improvements are actually being addressed with
the utility. White expressed a real concern with '"zeroing in" the
acute problems. Wickstrom stated that this is a 6 year program
to resolve the Mill Creek problem; complete the Lagoon facility
which resolves the 212th and 76th problem and a'.so the 180th
problem, and also implement some facilities up 'on the Garrison
Creek which will resolve the shopping center flooding and the
apartment flooding problem. In the first year of, the' utility, we
did the Upper Mill Creek Detention Basin. Next, 40 wanted to get
the Lagoon implemented to address some of the valley flooding,
which has effects on businesses and communities and everyone who
uses those roads with the primary emphasis being acquisition of the
balance of the right-of-way. In acquiring the right-.of-way we need
to complete the construction plans so we can proceed. We are also
targeting some money into the Mill Creek to detomine what the
Public Works Committee

solutions are and what we can afford to do.
White asked, recognizing that there is a jurisdictional question,
if there was any possibility we could do something along tho west
side of Mill Creek, even if only a couple of feet, possibly
sandbagging. Wickstrom explained that our first step would be to
determine what our options are. Possibly a combination of building
a levee along the west side with gates on the outlets so that the
west side does not backf low through the storm drain system and
flood in from behind, which is happening right now in some
instances, and maybe raising the elevation on the Earthworks to
hold some of the water and reduce the outlet. But until we can
hire some consultants to assist us to look at those problems we
cannot present a real solution. Wickstrom stated he has targeted
about $1.6 million in that basin to address both the flooding and
an erosion problem that is causing significant damage down through
the Earthworks reducing up the capacity of the whole system.
Getting the erosion out of the creek will preserve the capacity
longer and will require less maintenance time plus cut our costs.
Every time we clean the Earthworks it's a significant cost
($80,000) .
These are the real target areas for the program plus we have
targeted some money to continue to "put out storm drainage problem
fires" area-wide such as slides from some outfalls in the Cambridge
East area.
Dowell stated that he has heard from some of the neighbors to the
north, on Central, that at one point the water on the east side of
Central was 2 feet higher than the water on the west side of
Central. Meaning that either the pipes weren't big enough under
Central or they were too full of silt in order for the water to get
through. Wickstrom explained that when we re-built Central and re-
built the pipe capacity, we upgraded the capacity to match Bowen
Scarff's. Obviously we are not going to tear down Bowen Scarff's
to put in bigger culverts - we just tried to match the capacity
which is about 150 cfs.
Dowell stated he felt that the pipe was too small to handle and
equalize this build up of water, or possibly the pipes were full of
junk. Wickstrom explained that it could be a combination of both.
Dowell asked if there Is some way that we clean those pipes.
Wickstrom stated that we do clean them but we don't maintain that
channel. As we clean, when the next storm that comes, it just
washes material back in. Wickstrom explained that from James
Street north all the way up through 180th, Mill Creek is the
Drainage District's channel. They acquired the right of way in
,M
Public Works Committee

1929 for that and that has been their responsibility to maintain
since. We have taken over the closed systems. As development
occurs alongside, we have required easements so in the eventuality
the District goes out of business, at least we would have some
adjacent easements. We try to clean the pipes and prepare for
the winter storms on a yearly basis.
Wickstrom explained that the Drainage District is responsible for
the drainage channels and the drainage channels is where all the
silt accumulates. If this is contaminated it may be necessary to
haul it out to Arlington. We prefer to have the Drainage District
stay in business so that they are responsible. There is a
significant portion - 10,000 ft - of Mill Creek that is on DOE's
list as a contaminated site.
Dowell asked where their funds come from? Wickstrom stated that
they have taxing authority but if the district dissolves the City
would not get the taxing authority.
Dowell asked why didn't we just leave the water rate where it is
and just increase the drainage fees. Wouldn't that be a little
more honest to the citizens?
Wickstrom explained that the growth spurts we have hatd �outstripped
any projection in the water revenue and we have accumulated a
significant fund balance. Dowell stated that he understood that
the money was coming from the water fund to pay for the drainage
fund. Dowell then made reference to a note in the Storm Drainage
Utility report stating that later on we may have to have a water
increase.
Wickstrom explained that it depends on how things progress. If
under the Federal Safe Water Drinking Act we have to put in
infiltration plants then we will have a big expenditujre. We may
have to raise the water rates.
White inquired about the chances that we are not going to have
increased growth and that we are not going to have, to do these
filtration plants. Wickstrom stated that our first step is to pull
the balance of our transmission main customers bff the system.
That allows us the chlorine contact time through the system before
it gets to our first customer which means we may be able to defer
this treatment plant requirement beyond 1996 or longer.
Tony McCarthy explained that about two years ago the City received
a refund of almost $1 million in excise taxes an& 'Bost all of it
went into the water fund. That money has earned' interest since

then, plus we were paying a lower amount for state excise tax.
Wickstrom stated this is the first year's program. Once we
determine what we can do the priorities could change. This is a
schedule that we developed to try to address some of our biggest
concerns.
White questioned whether we could utilize the water funds now and
pay it back with drainage utility funds so some of projects can be
moved up.
Wickstrom stated that this plan was prepared in July of 1991 and we
thought we would implement it right away. We already have one
program funded except for the Lagoon conversion. Portions of the
1992 programs are funded too, so it looks we're ahead of the game
in terms of being able to do more projects.
White asked if there is anything we can do to push the Drainage
District to moving some of their clean up. Wickstrom stated they
budget about $70,OOOJyear. It is very difficult for them to get
permits from Fisheries.
At this time, Jim Hansen felt it would be a good idea to present
Council some options on priority. Some of these projects are
competing with one another, not just for the money but for time as
well. Since this is a six year plan, as we move through this
process of reviewing it with the citizens, we could also look at
juggling some of those priorities and'see if there is some approach
we could use we haven't thought of yet to get some of the high
priority ones addressed at the same time if that's possible. The
funding mechanism will be looked into by Tony.
Wickstrom stated that there are two things we could look at: One
is with this lag time shift - the significant 191 projects are
already funded and 192 have been funded by cash unencumbered fund
balances. We can increase the cash transfer to a fund to move some
of those projects up even further.
McCarthy commented that Finance is proposing to read the
residential accounts every three months. Right now they are being
read every second month and businesses are read monthly. Further
discussion followed between Dowell and McCarthy regarding the
"estimate" and "actual" readings of water meters.
White expressed concern at this time, regarding the length of time
that staff takes to get this process of reading meters done.

Dowell stated that there is a loss of 30 days income on the water
bill for the portion between, the estimate and thei actual use.
McCarthy stated that meters are read on one side of tdwn one month,
and the other side of town the next month.
Leona Orr commented on a problem with water bill that is averaged
out every month - it is to the advantage of the 'customer to pay a
bill every two months rather than writing a very sma,'11 one and then
an additional larger one the following month.
At this time, Wickstrom stated the item will be back again next
meeting with a revised schedule.
GARBAGE RATES
Wickstrom explained that Kent Disposal just svlmitted their
proposed rates asking us to review and approve them '�, o; they could
become effective January 1, 1592. We were under the assumption it
was all going to go to WUTC and at this point in time it would be
our recommendation to go to WUTC. We only have authority over
residential rates. WUTC may not want to revit*v,`�'Kent's rates
because Kent Disposal is under contract with the City of Kent.
Dowell asked when did we get the information that increased rates
were going to go' into effect? Wickstrom stated that we knew in
July that the dump fees were going to increase Ja.nu y' l. Dowell
asked why didn't we set the rates back in luljj Wickstrom
explained that we only review rates that are submitted to us. The
City does not set the rates. We did call Kent aiesal several
times but only received this information December 11th. The rates
also ref lect the King County policy on incentives ryto` recycle. Mrs.
Rust asked if the rates included a charge for recypl g. Wickstrom
responded stating that recycling is not part of t is ', contract -
recycling is a separate contract. After furtfi "discussion on
the timing of this issue, Dowell made a motion t,6 send this to
Council; seconded by Orr. Committee unanimously a6 lowed.
CROSSWALK ON 116TH AVEJSE 234TH STREETS
Ed White stated that the problem has existed since ,;ep roximately
1988. There has been correspondence between, the " City, School
District and County on this issue - evidently not' a whole lot of
action. A brief study of the area including visual survey, traffic
counts, and speed studies reveals there is no stre`etY lighting; this
is a two lane arterial with average speeds approetely 10 mph
over the posted 35 mph which is characteristic ; " rt,4is type of
facility. There is a slight grade going south ' north which
causes some visibility problem as well as a lack of lighting at the
Public Works Committee
December 17, 1991
Page 6
intersection. What complicates fur ability to correct any problem
is that our City limits goes right down the middle of 116th Avenue
SE - the west half of the strepti js within the City; the east half
is County. Anything that the pity proposes would have to be
concurred with by the County. We are currently in the process of
contacting the County again to;;,. see if they can assist us in
providing additional signing or other types of improvements - at
least concurring with correctives actions that staff will propose.
Ed White suggested recommended actions based on visual observations
as well as doing research on what things we can do.
The first is to provide advanced signing at the intersection with
slightly larger advanced and crosswalk signing made of a high
intensity site material. Another option would be to install cones
during the AM and PM hours to coincide with the King County. We
would see if there could be some type of cooperative effort for the
County to pay a portion of costs'to do whatever improvements would
be recommended. Jim White expressed concern about the County
paying. He stated he did not want to run it through another budget
cycle which is a year away. Ed White stated there could be a
certain liability issue here also which the County may or may not
opt to get involved.
Ed White explained that in talking with the School District, 234th
is within what they consider, a safe walking path. The School
District actually considers a gravel shoulder as sufficient for
walking as long as it is between 31 - 51 . Looking at a total
volume of traffic counts, there is approximately 8,000 vehicles.
Jim White asked if there was any possibility that the School
District would fund any portion of this. Ed White feels a
flashing light would be better than .a light with a "ped" button to
push because the pedestrian will, still proceed with caution most
times, with a flashing light. The, least restrictive, is having
nothing and it conveys an extreme amount of danger. By doing the
flashing beacon, you improve the, visibility. Dowell feels that a
point of negotiation should be made with the School District in
that when they build a school,; the School District should be
responsible for the infrastructure:; as in any development.
Jim White suggested that we go mead and do everything suggested,
at least come up withra budget fOr it, and work with the County on
getting approval. Jahn Bond suited that a street light would be
located on the southeast corner Facing 116th Avenue Southeast. Ed
White feels this should be sufficient to light the area. The
problem with trying' to get something on the other side is that
there is no power which increases the cost dramatically. Dowell
wanted to confirm the discussipn: a street light; a flashing
signal going directly over the cbswalk and then cones. Jim White
Public Works Committee

Page- 7
interjected that we would need the cooperation of the School
District for the cones because the City does not have the personnel
to handle them. Jim White stated he felt we should go ahead with
the plan and if we get money back from the County that's a plus.
Tom Brubaker stated there would be some time taken with the County
in securing the proper permits. Ed White's staff will work out
all the logistics in what to put out there and make the proposal to
the County and will wait for their concurrence.
