[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
