[0:57] we have the City Council with you with
our joining the Pledge of Allegiance
[1:01] place sort of the will call please
a or white here deputy mayor seller your
[1:23] councilmember time here counts member
Rodriguez cast members Sanchez just
[1:28] enter your change go to our general item
which is a doctrine of a resolution of
[1:34] ratifying the proclamation of a local
emergency honorable mayor in council
[1:38] members and staff gonna be providing a
presentation for you it's a
[1:43] recommendation to adopt a resolution but
an overview of the rain events on Friday
[1:48] and damages public infrastructure as a
result and so deputy chief Pete Lawrence
[1:55] will go first followed by Carey Dale and
then Kyle Coker and we will all be
[2:01] available for questions after the
presentation
[4:02] all right good afternoon honorable mayor
members of council people our
[4:05] institution Chiefs at the fire
department and I've been asked to give
[4:09] some context in some information
relating to the the storm that occurs to
[4:13] flash Friday so we had a week's worth of
rain but the important part is is that
[4:23] on Friday we set a single-day rainfall
record for Oceanside obviously it's
[4:27] tough Harbor it's not further inland but
we had a three point one eight inch
[4:32] today 24-hour days for parking at
midnight and those records there go back
[4:38] until 1909 so the most rain we've had in
a single day in any month throughout the
[4:47] the last 111 years so our biggest
problem as well with the rainfall rate
[4:52] we didn't just have one day of rain but
we had a whole week's worth of rain and
[4:57] we have very high 12 hour rate so we
have 12 2 inches of rain throughout the
[5:02] city through the course of the day and
it was falling on the back of a lot of
[5:08] rain that had occurred over the weeks
leading the saturated soil so the runoff
[5:14] that occurred on Friday was pretty
astronomical for all the flooding that
[5:19] we've had here in the city our call for
service both police and fire went up 50%
[5:25] there was a large quantity of people
that were in we were lucky that it
[5:29] wasn't the normal Friday where people
were out driving for their traffic
[5:32] accidents were not a huge component but
lots of calls for service ranging from
[5:37] fires to flooding calls to water rescues
to trees into into buildings we have a
[5:43] lot of tree failures again there trees
that fell over because of the saturated
[5:49] soil that we were encountering the
family or a river has been trending very
[5:57] low minimal water flow it's increase in
flow over a thousand percent in one day
[6:03] we went from a 7 foot height to a 16
foot height and to put that kind of in
[6:09] context just the flow and people talk
about cubic feet per second
[6:12] most people don't you know seven gallons
are they per cubic foot
[6:16] it went from 200 to 24,000 gallons per
minute to 2.5 million gallons per minute
[6:24] at its peak and so it keeps it a little
over 16 feet on Friday
[6:29] it went up immediately it was not a
gradual it was a very rapid rise so
[6:35] gives you an indication of the amount of
rain that fell not only here in
[6:38] Oceanside but in the henshaw Basin
basically and the sand where a valley so
[6:45] it's tremendous amount of water all at
once
[6:47] fortunately we didn't have any flooding
event of the dig breakthrough with the
[6:51] harbor and we ended up with a lot of
debris that traveled on to the beaches
[6:57] etc so emergency Proclamation this is
the first time since the 1990s we've had
[7:05] concurrence inversion serious running
and that was a flooding events where we
[7:09] got hit twice in the same month by
floods so we've had a local emergency in
[7:14] effect for the coronavirus a local
emergency was proclaimed by the city
[7:17] manager on the 10th of April and neither
the county nor any other cities within
[7:24] the county have proclaimed the local
emergency because this was a very
[7:27] localized kind of event it was pretty
much Del Mar to about midway through
[7:33] Camp Pendleton let's say like olga's
the rainfall that occurred in San
[7:37] Clemente was in the hundredths of an
inch versus in the multiple inches so
[7:43] you can see that this was basically a
stream of water that was aimed at the
[7:47] North County the city proclaimed the
local emergency because we did have
[7:51] significant damage and we both have
water they have water utilities and
[7:55] Public Works here to speak to the damage
that occurred to their individual
[7:59] facilities the reason I bring up that
neither the county nor the city has
[8:03] proclaimed the local emergency is
because it does make things a little bit
[8:07] more interesting for us as a city but we
do have a strategy for hopefully getting
[8:11] step or state financial aid I do not
anticipate that we will get any federal
[8:16] but we will be able to get reimbursement
assistance hopefully from the governor
[8:20] if we can't get it from the governor
then we're going to work toward the
[8:25] directors concurrence which we did in
1991 in 91 we had significant rainfall
[8:30] and we have damage to the Douglass
bridge we were one of the few cities
[8:34] with significant infrastructure damage
was about a million dollar repair and we
[8:39] were able to get the director to concur
that we had significant damage the
[8:43] downside is as we don't get any
emergency work covers we just get
[8:48] permanent work but that's our fallback
so we're hoping to be able to get
[8:53] through this emergency Proclamation hit
the emergency works and the emergency
[8:56] contracting taken care of and then move
towards trying to get reimbursement to
[9:00] the city we believe that we've got
sufficient damage to warrant a
[9:05] director's concurrence especially given
the economic impact that the Kovan virus
[9:10] is taking on the city's finances and so
that's what what we're going to be
[9:15] working towards at this point I'm going
to turn the presentation over to our
[9:19] water utilities director so we'll be
available if there's any additional
[9:22] comments or questions at the end of the
presentation
[9:42] bring that back up
[9:55] see that's an anon room here and Tulsa
members carry Jail what are you told the
[9:59] director appreciate the opportunity to
talk to you today about what we
[10:04] experienced last part it was pretty
significant that's Keith Lawrence
[10:09] mentions when we have that amount of
significant rainfall occurring in such a
[10:14] short amount of time it's typically
manifests itself in drainage through our
[10:21] waterways and especially additional
infiltration of rainwater and hits a
[10:26] gravity sewer system
the photo that I'm showing you here
[10:31] appears to be a river but it's actually
the 76 3 went 478 freeway that the El
[10:37] Camino overpass
it's looking south to the shops Metro
[10:44] Scott and I'm going to be talking about
a couple of different infrastructure
[10:49] issues that we have it it had in this
area specifically related to the
[10:54] flooding here before I go on to those
descriptions of those impacts I did want
[11:02] to also mention that in addition to
these sewer issues we did have water
[11:07] crews that were very busy on Friday
supporting the Public Works staff in
[11:12] responding to some of the landslide
issues that you'll hear Kyle talk about
[11:20] so the silver lining in this emergency
is that we actually do well with some of
[11:25] our projects one of them being the
emergency work to protect the manhole at
[11:32] TMR Drive City Council had declared an
emergency for repair work on February
[11:38] 26th that manhole is adjacent to the
eastbound lane in the 78 freeway just to
[11:48] the east of the El Camino overpass this
is a picture of that site and here you
[11:54] can see if I can if you want to look at
the screen there's a dark image here
[11:59] that's sheet so showing that was put in
place to divert flow away from the
[12:04] manhole so we didn't have further
erosion the contractor had also worked
[12:11] through a previous story a few weeks
prior and was successful in it's
[12:16] affecting a man's life the picture on
the left is a close-up of the sheets off
[12:23] shoring which helps to divert the stream
flows away from the manhole and on the
[12:27] right are additional boulders that were
put in place to protect the manhole so
[12:33] from this perspective we did very well
we did not have any sort of ruptured
[12:38] pipe or a ruptured manhood so ever we
did experience overflows and
[12:48] infrastructure damage at three others
lights in the city the first one being
[12:53] the Buena Vista lift station which is
located just west of that flooded
[12:58] picture I showed you on the 78th so one
of if the lift station is located south
[13:04] of the 78 freeway in the parking cooking
area of the mall
[13:11] this is the aerial view of the site here
a little over two acres and it has an
[13:17] abandoned treatment facility outside as
well as two separate lift stations and
[13:22] old the station and new lift station
[13:31] this is a video that our crew took of
the berm that butts up against it one of
[13:38] us to Creek and to the last you'll see
that the Berlin breach before it flood
[13:44] waters were filling into the site and
everything was under water pumps motors
[13:52] electrical switch gear this is another
aerial photo taken later in the day on
[14:01] Friday when we've had an opportunity to
actually get a drone up when the rain
[14:05] stopped for a little bit I think it was
about 6:30 p.m. you'll see the site is
[14:10] totally under water again it's adjacent
to the point of a secrete just on the
[14:15] top part of the photograph
[14:22] this picture shows one of our three of
our five motors that have been a total
[14:30] loss at the station this was taken on
Saturday after some drainage had
[14:35] occurred we also lost two blowers and
blower fans three drive shafts and
[14:44] bearings three check valves will have to
be rebuilt the damage to the electrical
[14:49] equipment as you can imagine is
significant it really does not like to
[14:54] be wet and we've lost five soft starters
five contactors murder favors breakers
[15:00] electronics and SCADA hardware
[15:07] this picture was taken Saturday after
significant drainage had occurred so in
[15:13] total or preliminary estimates of
damages at the site to restore
[15:18] facilities is approximately $500,000 up
until the time that the site was flooded
[15:28] the station was working and checking
sewage for treatment of tourists
[15:32] analysts for a plant when it was flooded
and pumps were no longer able to convey
[15:38] the sewage for treatment we did still
approximately 1.2 million gallons into
[15:43] the crease as with the next projects
that I'll talk about we have been in
[15:51] contact with the regulatory agency to
give them a preliminary heads-up about
[15:56] the issues that we had experienced on
farting in addition we also had
[16:06] significant drainage that came in to the
gravity sewer system leading into the
[16:11] ocean side full of artless station which
is located on Oceanside Boulevard and
[16:15] i-5 just to the left this is a picture
of Vine Street where we had water coming
[16:23] up to remember this is one of several
areas where we had water coming up into
[16:29] the street and in total the amount
spilled was thirty-eight thousand
[16:35] gallons
[16:41] additionally our main wastewater
treatment facility the demonstrate water
[16:46] reclamation facility of the North River
Road also experienced difficulties this
[16:53] is a picture of our scada flow trends
and brown the squiggly line that you see
[16:58] going up and down that is the raw
influence or the amount of raw sewage
[17:03] that was coming into the plant in brown
the blue trail shows the flow that
