Evacuation Route Assessment 1-3 February 2024

1.0 Introduction

1.1. Background
Chula Vista (City) is currently undergoing an update to the Safety Element of the City’s General Plan as required by California Government Code Section 65302 to address the need to protect citizens from risks associated with natural and human-caused hazards. In parallel with the Safety Element, a Vulnerability Assessment is required to satisfy California Senate Bill (SB) 379 to identify risks climate changes poses to the local jurisdiction and the geographic areas at risk from climate change. The Vulnerability Assessment identifies specific natural hazards related to climate change and evaluates the City’s vulnerabilities accordingly. The Vulnerability Assessment considers physical threats to critical facilities within the City as well as physical threats to residential and non-residential structures. The vulnerability findings will then inform adaptation and resilience goals, policies, objectives, and implementation measures in the Safety Element Update. It should be noted that a Vulnerability Assessment was conducted by San Diego County as part of the Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) and is included in the Safety Element for reference.

Hazards that may require an evacuation declaration include wildfires, floods, hazardous materials exposure, geologic hazards, and seismic hazards. This Evacuation Routes Assessment address the evacuation planning for potential emergency scenarios.

1.2. Legislative Overview
Under Assembly Bill (AB) 747 the City’s Safety Element needs to address evacuation planning for any emergency scenarios that would warrant an evacuation of populations within the affected areas. The evacuation planning is a component of the Safety Element (SE)). This requirement became effective as of January 1, 2022 and is required for the development of a new or updated SE. In addition, Senate Bill (SB) 99 also addresses local Safety Elements and emergency evacuation routes. This legislation requires the City to identify residential developments in hazard areas that do not have at least two emergency evacuation routes.

AB 1409 includes additional requirements for the Safety Element be periodically reviewed and updated.

It also requires that the SE include evacuation locations in the evacuation route planning.

This Evacuation Routes Assessment report includes a capacity analysis that identifies evacuation routes and their capacity, safety, and viability under a range of emergency scenarios applicable to the local jurisdiction. This report contains important information that will serve as a resource to the Evacuation Coordinator, Emergency Manager, and emergency management support personnel to more quickly assess and plan mitigative actions for local hazard scenarios that may lead to the eventual need to order an emergency evacuation of all or a portion of populations within the City.

2.0 Evacuation Routes Assessment

2.1. Designated Evacuation Zones
Emergency evacuation zones for the City of Chula Vista have been developed at the County level as part of the San Diego County Zonehaven EVAC Evacuation Pre-Plan modeling program. These zones have been developed through close coordination with City staff and the Chula Vista Fire Department. Zonehaven creates online data driven smart zones that are reviewed, adjusted, and approved by local law, fire, and city staff. Zonehaven EVAC is a web-based application for first-responders to add evacuation pre-plan data and make operational decisions on changing the status of a zone during an ongoing incident.

For the purposes of this evacuation assessment, multiple Zonehaven zones were aggregated into designated evacuation zones based on logical boundaries (typically following roadways) and similar access to evacuation routes for each of the hazard scenarios that have been considered. Only areas within the City that are considered to be at risk for these hazard scenarios are shown. Zonehaven maps and corresponding list of zones are included in Attachment A. As shown in Exhibit 2-1, the designated evacuation zones were categorized into two types, Fire Evacuation Zones (FEZ) and Dam Inundation Zones (DIZ). Additional assessment for these hazard scenarios is provided in Chapter 4.0.

2.2. Evacuation Reception Centers
Dependent upon the nature of a disaster, evacuees may have the option to evacuate to an evacuation reception center located in the immediate vicinity of the disaster.

Chula Vista has pre-identified shelters throughout the City that have been vetted by the Red-Cross and can be used as long as individuals have been directed there by first responders and the shelter has not been damaged by a disaster. Dependent on the incident, one or more of these sites could be activated as a temporary evacuation point or an overnight shelter. City staff in coordination with the Red Cross would make the determination to activate as events unfold. These locations are identified in Table 2-1 and shown in Exhibit 2-2.

2.3. Evacuation Route Vulnerability Assessment
Evacuation route vulnerability can be expressed from several perspectives. The most direct expression of route vulnerability deals with physical features along an evacuation route that can be damaged during emergency scenarios and cause the evacuation route to be disrupted and unusable. These physical features include:
 Bridges (over rivers, creeks, and other drainage features)  Bridges (creating grade separated roadways)
 Low points along the route that are prone to flooding  Route locations along steep natural slopes that are prone to landslides Exhibit 2-2 depicts physical features such as bridge structures along primary evacuation routes that may impede an evacuation if damaged at the time of an emergency which require an evacuation. The Vulnerability Assessment (separate cover) summarizes all of the critical facilities throughout. Table 2-2 below shows all of the bridges throughout the City, including those crossing the Ballona Creek and the Metro E (Expo) Line.

Evacuation Route Assessment 2-9 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A Evacuation route vulnerability can also be expressed in terms of vulnerability to residents where development areas are isolated and/or areas that have access to only one evacuation route. These areas are a concern and require additional advanced planning to address emergency scenarios where an evacuation is needed, and the single evacuation route may be blocked or damaged and cannot be used.

Shown in Exhibit 2-3 and summarized in Table 2-3, are those residential development areas (neighborhoods) that have only one access point to a primary evacuation route. These neighborhoods were identified after a thorough review of various City-wide maps and aerial photographs and include residential developments that may be access constrained during an evacuation. If a neighborhood takes direct access to another roadway and that roadway funnels to more than one designated evacuation route, it would not be considered vulnerable. Similarly, if a neighborhood does take direct access to a designated evacuation route with only one way in and out, this would be considered a vulnerable neighborhood.

In an evacuation scenario, these neighborhoods could be exposed to an increased risk due to the lack of multiple egress opportunities and should be given earlier evacuation consideration.

2.4. Designated Evacuation Routes
Evacuation routes effectively include all improved (paved) roads within the City. Unpaved roads may be used in an evacuation as a last resort but should not be relied on as a primary evacuation route. Local streets typically serve as direct access for adjacent residential and commercial development and while they are not designed to accommodate high traffic volumes, they serve limited development areas and are rarely required to handle traffic flows that would exceed their capacities, even under full evacuation conditions.

For the purposes of evacuation planning, the designated evacuation route street network includes roadways that are classified as collectors and above including the following:

1. Freeways/Highways

2. Major Roadways

3. Gateway Streets

4. Urban Arterials

5. Commercial Boulevard

6. Neighborhood & Local Streets (in select areas)
Designated evacuation routes are the most reliable roadway facilities for the following reasons:
 These roads are designed to accommodate higher volumes of traffic in-line with their classifications.
 Access controls are more stringent on roads of higher classification.  Intersection controls are designed to prioritize travel on roads of higher classification.  Roadway maintenance policies prioritize roads of higher classification.

Primary evacuation routes are identified in Exhibit 2-4. Note that evacuation routes shown are to gateway exit points located at or near the City boundary (refer Section 2.5). In addition, SR-125 is identified as a importation evacuation route, and while it is a toll road under emergency evacuation conditions it is presumed the evacuees would be able to access the highway without penalty or fees.

Evacuation Route Assessment 2-12 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A Exhibit 2-4: Primary Evacuation Routes

2.5. Evacuation Route Capacity
While the City’s Circulation Element roadways are designed to serve two-way traffic, the designated of evacuation routes are assumed to use only one direction of travel in the outbound direction away from the hazard. Once the evacuation order has been made, the inbound direction is typically reserved for emergency management vehicles to transport personnel and equipment towards the hazard.

The technical definition of the maximum capacity of a road is the maximum hourly rate at which vehicles can reasonably be expected to traverse a point during a given time period under prevailing roadway, traffic and control (free-flow) conditions. The capacity of an evacuation route considers the following factors:
 Design characteristics of the roadway (i.e., lane width, shoulder width, horizontal and vertical alignment, presence of raised median)
 Number of lanes in the outbound evacuation direction
 Access control
 Percent truck traffic

Evacuation Route Assessment 2-13 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A The maximum “free-flow” (uninterrupted flow) capacity of a roadway segment occurs at level of service (LOS) E when the vehicle speed and vehicle spacing is at its optimum level. Under the free-flow condition, the traffic demand is fully serviced, and the service volume increases as the traffic volume and density increase, until the service volume reaches the maximum LOS E capacity for the roadway segment. As traffic volumes and the resulting vehicle density increase beyond this "critical" value, the rate at which traffic can be serviced quickly drops below the maximum capacity. Therefore, to realistically represent traffic handling capacity during congested forced flow conditions (such as during an evacuation) it is necessary to apply a capacity reduction factor. A capacity reduction factor of 0.9 (10% reduction) has been applied based upon studies that identified a fall‐off in the maximum service flow rate (e.g., maximum capacity) when congestion occurs at “choke points” on a freeway segment. The estimated hourly vehicle capacities under forced flow evacuation conditions are summarized in Table 2-4 for each of the five designated evacuation route classifications.

(1) Assumes 30% of the available capacity will be consumed by ambient/background (non-evacuation) traffic.

It is important to note that the hourly evacuation capacity estimates shown in Table 2-3 may not be fully available to evacuating traffic during the early stages of an evacuation unless strict perimeter traffic control/access has been established before the evacuation order has been given. Depending on the time of day, conditions without positive perimeter traffic control could result in background (non-evacuation) traffic consuming between 25% and 30% of the available capacity during midday and non-peak periods.

Peak period background traffic on some higher classification roadways (including those that access freeway interchanges) could represent between 70% and 100% of the available capacity. If an evacuation occurs during peak periods, perimeter traffic control will be more crucial and certain evacuation routes may not be available for use. Conversely, during late evening and early morning periods, available roadway capacity on non-freeway routes would be greater than 90% of the maximum capacity.

At grade intersection controls at locations where two designated evacuation routes merge are also an important consideration during an evacuation. The approaches to at-grade intersections are where flow

Evacuation Route Assessment 2-14 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A can be “interrupted” by a control device or by turning or crossing traffic at the intersection. Due to the differences in the flow conditions at intersections, separate estimates of capacity must be made for these locations. In many instances, the approach to the intersection is widened through the addition of one or more lanes (turn bays), to compensate for the lower capacity of the approach caused by the interruption of traffic flow due to the intersection control device.

Minor intersections are typically controlled by “stop” signs on the minor street approach(es) or at all intersection approaches if the streets serve similar traffic volumes. Arterial street intersections are typically controlled by traffic signals and the amount of green signal time is assigned to the intersection approaches based on the relative traffic volumes.

During an evacuation, at‐grade intersections will likely become the first bottleneck locations once the evacuation is fully underway. During these conditions where traffic flows are concentrated in one direction and normal opposing traffic turning conflicts do not require signal intervention, traffic signals will not be able to efficiently manage the unique traffic demand pattern. This anticipated condition will result in the need to allocate right-of-way time to the respective competing traffic flows by imposing some form of proactive control. During evacuation conditions, control at the most critical intersections will often be provided by designated traffic control crews. In these cases, manual traffic control would supersede the normal stop sign or traffic signal control devices.

2.6. Distance & Travel Time to Evacuation Gateways
As part of the evacuation route assessment, the most direct evacuation routing from the evacuation zones shown in Exhibit 2-1 to the closest primary evacuation gateways exiting the City was identified. City evacuation route gateways include the following:
 Primary Gateways:
o Gateway A – I-5 (North)
o Gateway B – I-805 (North)
o Gateway C – SR-125 (North)
 Secondary Gateways:
o Gateway D – I-5 (South)
o Gateway E – I-805 (South)
o Gateway F – SR-125 (South)
The gateways have been separated into two categories: Primary Gateways (A,B & C) and Secondary Gateways (D, E, & F). While Secondary Gateways may be the closest for residents located in the southern parts of the City, most destinations are likely to be to the north, not the south.

It should be noted that not all evacuation zones were assigned to each Gateway since individual gateways may not be a convenient or logical exit point for all zones. A centroid was placed at logical cross-streets approximately in the center of each zone (or sub-zone) as shown in Exhibit 2-5. Recommended evacuation traffic routing was then assigned from the centroid to the most convenient Gateway shown above.

Evacuation Route Assessment 2-15 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A Exhibit 2-5: Evacuation Zone Centroids & Gateways

As a measure of evacuation vulnerability, travel time to each of the primary gateways was estimated for populations within each of the evacuation zones. To estimate the travel time from the centroid to the destination Gateway, the length of individual roadway segments, posted speed limits on each segment, and traffic control devices along the route (all-way stop, side-street stop, and traffic signal) were identified for each evacuation route. Travel time for each route segment was calculated based on the travel distance and posted speed. Typical intersection delay was estimated separately and was added to the segment travel time. An average delay factor of 20 seconds was used for each signalized intersection along the evacuation route. If an evacuation route passed through an unsignalized intersection, a delay factor of 10 seconds was applied if the routing passed through a stop-controlled approach. The sum of the individual roadway segment travel times and the total intersection delay were used to estimate the total travel time.

A summary of the travel time estimates for each zone to the various Gateways is included in Attachment B.

It is important to note that the estimated travel time is not an estimate of evacuation time, it is simply a calculation of uncongested, free-flow travel from the centroid of the evacuation zone to the assigned Gateway. As multiple zones are evacuated over time, the cumulative evacuation traffic will approach the

Evacuation Route Assessment 2-16 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A roadway capacity and may eventually exceed the available capacity of an evacuation route as they get closer to the evacuation Gateways. This results in congested conditions which would reduce the travel speed, and therefore increase the travel time to a Gateway.

As mentioned above, the assignment of emergency response crews at key locations to control the flow of traffic would help to significantly reduce delay times. While the free-flow travel time does not represent the evacuation time, it does provide a relative measure of the evacuation zones that would be subject to longer evacuation times. An evacuation order should consider these more remote areas and they should be prioritized in the sequencing of evacuation notifications.

The timing of evacuation notifications should consider the following factors that affect evacuation time:

1. Evacuee response time to evacuation notification (i.e. time for all evacuees to receive warning and time to prepare to leave home);

2. Estimated travel time to evacuation route gateway; and

3. Estimated added delay time due to evacuation route capacity constraints.

If the critical roadway segment that will have the limiting capacity during an evacuation can be identified, the approximate evacuation time can be calculated by dividing the number of evacuating vehicles using the critical roadway segment by the outbound capacity of the critical roadway segment. The critical segment could be located close to the evacuation zone in cases where the evacuation is limited to one or two zones. In cases where multiple zones are evacuated at the same time, the critical roadway link will likely be closer to the evacuation route gateway where the accumulation of evacuating traffic is the greatest.

Exhibit 2-6 through Exhibit 2-15 identify the designated evacuation route from the centroid of each evacuation zone to assigned Gateways throughout the City and summarize the travel times to individual Gateways. Exhibit 2-16 and Exhibit 2-17 shows the evacuation route to the nearest Gateway for each evacuation zone for the fire hazard and dam inundation scenarios. Table 2-5 summarizes the travel time estimates rounded to the nearest quarter of a minute (15 seconds)

3.0 Safety & Traffic Control Considerations
As noted earlier, at‐grade intersections will likely become the first bottleneck locations once the evacuation is fully underway. During these conditions traffic signals and stop sign controls will not be able to efficiently and safely manage the evacuation traffic demand pattern. In order to maintain a safe and efficient traffic flow, it will be necessary to allocate right-of-way time to the respective competing evacuation traffic flows by imposing some form of proactive control. During evacuation conditions, manual control at the most critical intersections should be provided by designated traffic control personnel. Considering the designated evacuation routing for the City’s evacuation zones and the points where major evacuating traffic flows will be merging, it is recommended that manual traffic control be considered at the locations identified in Table 3-1 and shown in Exhibit 3-1.

Exhibit 3-1: Manual Traffic Control Points

The need for manual traffic control at these locations will be determined by the Evacuation Coordinator and Emergency Operations Manager. Locations that should have manual traffic control established will depend on the hazard scenario being addressed and the evacuation zones that are ordered to be evacuated. In most cases, the City’s Police Department would be responsible for providing the personnel needed for the manual traffic control function.

4.0 Primary Evacuation Scenarios
Through coordination with the City’s Public Works Department, as well as the Police and Fire Departments, two representative emergency scenarios have been identified which would require an evacuation of populations within select evacuation zones within the City. The two emergency scenarios include a potential fire hazard scenario and a potential dam inundation scenario. The following sections present a discussion of each emergency scenario along with the identification of corresponding evacuation procedures and recommendations for facilitating the evacuation in the event of a significant emergency.

4.1. Scenario 1 – Wildfire Hazard
This scenario represents a potential fire hazard approaching from the east through the San Diego National Wildlife Refuge, Proctor Valley, and the Otay Open Space Preserve burning towards the City limits. As identified in the Vulnerability Assessment, portions of the City along the easterly and southerly boundaries are identified as very high hazard zones – see Attachment C. A wildfire in any of these zones could potentially spread into the City and threaten residential structures but are unlikely to immediately impact critical facilities.

As shown in Table 4-1, facilities within the fire hazard zones include the several pump stations, the Chula Vista Transit Center, and the Fresnius Medical Care (Marina Bay).

Table 4-2 summarizes the number of residential buildings for each of the evacuation zones within the fire hazard zone and the estimated number of vehicles associated with these residences. The estimated number of personal vehicles is based on vehicle ownership data prepared by County of San Diego, Health and Human Services Agency, Public Health Services, Community Health Statistics Unit (2023) for the City of Chula Vista.

If a fire hazard were to occur in the hills and open space to the east of the City, Evacuations Zones FEZ-6, FEZ-8, and FEZ-10 through FEZ-13 would potentially experience the highest risk since they are located along the City’s eastern boundary closest to the fire hazard. Residents in each of these zones should be directed to travel west, away from the fire hazard. As shown in the travel time assessment above, the closest gateway to these zones are along SR-125 toll road (Gateway C to the north and Gateway F to the south). However, depending on the nature, origin, and direction of a potential fire hazard, these gateways may lead them closer to the hazard and evacuees in this case should be directed to continue west toward other gateways. The estimated travel time from these zones to the closest gateways ranges from 5.75 minutes to approximately 12 minutes; however, as discussed in Section 1.2.6, these travel time estimates are not equivalent to evacuation times and should only be uses as a relative comparison for individual zones.

If a fire hazard were to occur in the Otay River Basin to the south of the City, Evacuations Zones FEZ-2, FEZ-4, and FEZ-6 would potentially experience the highest risk since they are located along the City’s south eastern boundary closest to the fire hazards. While the closest gateways (Gateway E and Gateway F) show relatively fast travel times, these gateways would likely lead them closer to the hazard and residents should instead be advised to travel north towards Gateway B and Gateway C.

Evacuation Route Assessment 4-3 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A The evacuation routes serving these hazard zones, including Proctor Valley Road/East H Street, Otay Lakes Road / Telegraph Canyon Road, and Olympic Parkway are either 4-lane or 6-lanefacilities (two to three lanes in each direction) with a one-way outbound evacuation capacity of between 2,390 and 3,590 vehicles-per-hour (vph). In total, all fire hazard evacuation zones throughout the City have an estimate of 25,984 dwelling units, or approximately 46,485 vehicles that could potentially be evacuated due to a fire hazard. However, with the multiple evacuation route options available to residents, it is unlikely that each resident would take exactly the same route. Additionally, the staggered evacuation response by evacuating residents would also spread the evacuating traffic loading on the evacuation routes over time.

Therefore, the available capacity of the roadway network is estimated to be sufficient for this hazard scenario. To avoid significant congestion, incremental evacuation of these zones should be considered if advanced warning of the fire hazard permits.

In addition, while SR-125 is a toll road that charges a fee to use (typically via a transponder or license plate reader), under emergency conditions it is imperative that toll fee collection be suspended until the evacuation orders are lifted. This limits the level of conflicts residents would face during an evacuation and helps to disperse evacuation traffic loading throughout the evacuation route network.

4.2. Scenario 2 – Dam Inundation
This scenario represents a potential failure at the Sweetwater Main Dam and Reservoir which lies approximately 1.5 miles to the north of the City limits. A failure at the dam could potentially inundate residential neighborhoods and critical facilities shown in Table 4-3. Dam inundation maps are provided in Attachment D.

A failure at the Sweetwater Main Dam would follow the Sweetwater River through the Bonita Golf Club, Sweetwater Regional Park, Chula Vista Golf Course, the Sweetwater River Park before finally reaching the San Diego Bay. Within the City limits, the homes surrounding the Chula Vista Golf Course between Bonita Road and Sweetwater Road would experience the highest threat levels.

The inundation maps show that flood waters flow downhill following lower elevations toward the San Diego Bay and would reach a maximum depth of more than 18 feet on average and potentially up to 42 feet. The maps show initial floodwaters would reach the Chula Vista Golf Course within 22 minutes with a maximum flood depth of 29 feet at it’s peak (within 41 minutes). Floodwaters would continue to flow towards San Diego Bay and reach the I-805 interchange in approximately 55 minutes with the sections of SR-54 at risk of being flooded. The Flood inundation maps show that water would likely flow along the SR- 54 under reach the I-5 interchange within 1 hour and 23 minutes.

This flooding would likely impact the availability of evacuation routes and could hinder the efficient evacuation in the event of an emergency scenario. Evacuation routing should follow a path to higher ground (higher elevation) away from the flood zone (i.e., south). While the nearest gateway (Gateway B) to the evacuation zones show travel times between 3.5 minutes and 8.75 minutes, this could be potentially be impacted by the flood inundation hazard and evacuees should be directed toward other gateways via alternate routes.

Evacuation Route Assessment 4-4 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A It should also be noted that the SR-125, I-805, and I-5 freeways are elevated roadways and are not anticipated to be significantly impacted by floodwaters. However, the SR-54 roadway is at a lower elevation and would experience the highest threat of flood as it travels parallel to the Sweetwater River.

SUM 3,124 5,589

Dam Inundation Zones DIZ-4 and DIZ-5 would be immediately threatened by this potential dam inundation hazard. Zone DIZ-4 should be directed to head north outside of the City limits via Sweetwater Road towards Gateway B or Gateway C (nearest) and could potentially evacuate an estimated 177 dwelling units, or 317 vehicles. Sweetwater Road is a 2-lane facility (one lane in each direction) with a one-way outbound capacity of 1,200 vehicles-per-hour (vph).

Zone DIZ-5 should be directed south on Otay Lakes Road, which is a 4-lane facility (two lanes in each direction) with a one-way outbound evacuation capacity of 2,390 vehicles-per-hour-per (vph). All of Zone DIZ-5 could potentially evacuate an estimated 513 dwelling units, or 918 vehicles, however only those residents north of Allen School Lane are shown to be at risk of flooding.

It should be noted that the Willow Street Bridge connecting Bonita Road and Sweetwater Road over the river, while elevated, could be potentially at risk of flooding and should not be utilized. Similarly, Bonita Road runs parallel to the river and is also at risk of flooding and should not be utilized.

With the multiple evacuation route options available to residents, it is unlikely that each resident would take exactly the same route. The dispersion of traffic would reduce the evacuation loading on any given

2 Data Sources: Incorporated City Limits from CalFire, January 2017. Licensed Healthcare Facilities, Schools, Fire Stations and Law Enforcement Facilities from SanGIS, February, 2019. Highways are from CalTans, 2018

1. This map was developed for the benefit of local emergency managers and the California Governor's Office of EmergencyServices. The information shown is approximate and should be used as a guide for emergency response and preparation.

2. The inundation map meets all applicable state and federal standards and has been prepared in consideration of potentialdownstream hazards by a licensed civil engineer.

3. The results presented herein do not reflect the structural integrity of the dam and are not a statement of the dam's safety.The analysis presented is based on a hypothetical dam failure of Sweetwater Main Dam using 2D modeling software.

4. Cross Section Values:Distance from Dam and Stationing are reckoned from the centerline of Sweetwater Main Dam along the displayed Flow Path.Distance from Dam is in miles and Stationing is in feet (Stationing 12+34 = 1,234').Initial Wave Arrival Time, 1 Foot is the time to achieve 1 foot of water depth after initiation of the dam break.Time to Peak is the time to achieve the maximum water depth after initiation of the dam break. 2:00
0 500 1,000250 Feet
0 0.125 0.25Miles

4. Cross Section Values continued:Peak Inundation Depth is the maximum water depth in feet.Peak Velocity is the maximum velocity in feet per second.Peak Discharge is an estimate of the maximum flow rate integrated over the entire cross section line in cubic feet per second.Peak Water Surface Elevation is the maximum water surface elevation in feet.Location Description indicates major roads that cross, or are near, the Flow Path at that cross section.

5. The values displayed in the table for each cross section are the maximum for that parameter along each cross section line, except for theInitial Wave Arrival Time, 1 Foot and Time to Peak which are the minimum for that parameter along each cross section line.

6. For other details refer to the supporting report "Sweetwater Main Dam Inundation Technical Study" February 2019.

7. Structures are shown in the aerial photo on the maps but may not clearly display all possible structures potentially within the inundation limits.

8. Map projection: State Plane, California Zone VI, Feet, North American Datum 1983. Border Tics display these coordinate values.All elevations are referenced to North American Vertical Datum 1988.

2 Data Sources: Incorporated City Limits from CalFire, January 2017. Licensed Healthcare Facilities, Schools, Fire Stations and Law Enforcement Facilities from SanGIS, February, 2019. Highways are from CalTans, 2018

1. This map was developed for the benefit of local emergency managers and the California Governor's Office of EmergencyServices. The information shown is approximate and should be used as a guide for emergency response and preparation.

2. The inundation map meets all applicable state and federal standards and has been prepared in consideration of potentialdownstream hazards by a licensed civil engineer.

3. The results presented herein do not reflect the structural integrity of the dam and are not a statement of the dam's safety. The analysis presented is based on a hypothetical dam failure of Sweetwater Main Dam using 2D modeling software.

4. Cross Section Values:Distance from Dam and Stationing are reckoned from the centerline of Sweetwater Main Dam along the displayed Flow Path.Distance from Dam is in miles and Stationing is in feet (Stationing 12+34 = 1,234').Initial Wave Arrival Time, 1 Foot is the time to achieve 1 foot of water depth after initiation of the dam break.Time to Peak is the time to achieve the maximum water depth after initiation of the dam break. 2:00
0 500 1,000250 Feet
0 0.125 0.25Miles

4. Cross Section Values continued:Peak Inundation Depth is the maximum water depth in feet.Peak Velocity is the maximum velocity in feet per second.Peak Discharge is an estimate of the maximum flow rate integrated over the entire cross section line in cubic feet per second.Peak Water Surface Elevation is the maximum water surface elevation in feet.Location Description indicates major roads that cross, or are near, the Flow Path at that cross section.

5. The values displayed in the table for each cross section are the maximum for that parameter along each cross section line, except for theInitial Wave Arrival Time, 1 Foot and Time to Peak which are the minimum for that parameter along each cross section line.

6. For other details refer to the supporting report "Sweetwater Main Dam Inundation Technical Study" February 2019.

7. Structures are shown in the aerial photo on the maps but may not clearly display all possible structures potentially within the inundation limits.

8. Map projection: State Plane, California Zone VI, Feet, North American Datum 1983. Border Tics display these coordinate values.All elevations are referenced to North American Vertical Datum 1988.

2 Data Sources: Incorporated City Limits from CalFire, January 2017. Licensed Healthcare Facilities, Schools, Fire Stations and Law Enforcement Facilities from SanGIS, February, 2019. Highways are from CalTans, 2018

1. This map was developed for the benefit of local emergency managers and the California Governor's Office of EmergencyServices. The information shown is approximate and should be used as a guide for emergency response and preparation.

2. The inundation map meets all applicable state and federal standards and has been prepared in consideration of potentialdownstream hazards by a licensed civil engineer.

3. The results presented herein do not reflect the structural integrity of the dam and are not a statement of the dam's safety.The analysis presented is based on a hypothetical dam failure of Sweetwater Main Dam using 2D modeling software.

4. Cross Section Values:Distance from Dam and Stationing are reckoned from the centerline of Sweetwater Main Dam along the displayed Flow Path.Distance from Dam is in miles and Stationing is in feet (Stationing 12+34 = 1,234').Initial Wave Arrival Time, 1 Foot is the time to achieve 1 foot of water depth after initiation of the dam break.Time to Peak is the time to achieve the maximum water depth after initiation of the dam break. 2:00
0 500 1,000250 Feet
0 0.125 0.25Miles

4. Cross Section Values continued:Peak Inundation Depth is the maximum water depth in feet.Peak Velocity is the maximum velocity in feet per second.Peak Discharge is an estimate of the maximum flow rate integrated over the entire cross section line in cubic feet per second.Peak Water Surface Elevation is the maximum water surface elevation in feet.Location Description indicates major roads that cross, or are near, the Flow Path at that cross section.

5. The values displayed in the table for each cross section are the maximum for that parameter along each cross section line, except for theInitial Wave Arrival Time, 1 Foot and Time to Peak which are the minimum for that parameter along each cross section line.

6. For other details refer to the supporting report "Sweetwater Main Dam Inundation Technical Study" February 2019.

7. Structures are shown in the aerial photo on the maps but may not clearly display all possible structures potentially within the inundation limits.

8. Map projection: State Plane, California Zone VI, Feet, North American Datum 1983. Border Tics display these coordinate values.All elevations are referenced to North American Vertical Datum 1988.

Evacuation Route Assessment 4-5 February 2024

Ev acuation Ro ut e Cap aci ty and Viab ility Stu d y CIT Y OF C HU LA VI ST A evacuation route. To avoid significant congestion, incremental evacuation of these zones could be considered if advanced warning of the flood hazard due to the dam breach permits.

Given the distance to Sweetwater Dam and Reservoir, Inundation maps show that initial flood waters will reach the City in just less than 25 minutes. Given the time between the dam breach and flooding effects that would impact or make evacuation routes unusable, it will be critical to develop advance warning methods that would identify a likely breach of the dam so the preemptive evacuation order could be given. One such example would be an earthquake event that causes damage to the dam but does not immediately cause a dam breach. Under some emergency scenarios such as an earthquake that does cause immediate rupture or dam breach, it may not be possible or practical to declare a vehicle-based evacuation and a shelter in place order may be more appropriate.
