1 Issue: Evacuation Planning and Preparedness Update. 2 3 Recommendation: Receive report/presentation and provide feedback. 4 5 Background: Following the Tubbs Fire in October 2017, City Council became increasingly 6 interested in evacuation planning in Mill Valley. At that time, now Vice-Mayor McCauley asked 7 questions of staff related to Mill Valley's plans, which revealed the City did not have a detailed 8 understanding of the time necessary to complete a full citywide evacuation in the event of a 9 conflagration. This information is critical to real-time decision making about the timing and scope

10 of an evacuation announcement. 11 12 As a result, the City made inquiries to CalFire, other state fire agencies, academic institutions, and 13 local urban planners to learn more about evacuation timing estimates. Unfortunately, at that time, 14 the City could not find a qualified partner to perform a study that would further understanding of 15 the dynamics involved in city-wide evacuation timing. This is not an issue limited just to Mill 16 Valley. 17 18 Following the Paradise Fire in November 2018, understanding the speed of evacuation took on 19 greater urgency given the fire risk profiles and other similarities between both communities. 20 Although the City of Paradise had developed a similar evacuation plan as Mill Valley, Paradise 21 was still overwhelmed by the speed and severity of their devastating fire and the time needed to 22 evacuate the community. 23

ITEM 8

City Council Staff Report Evacuation Planning and Preparedness Update March 15, 2021

24 As the City was unable to find a traditional vendor to assist in understanding the timing of a full 25 city-wide evacuation, Vice-Mayor McCauley contacted a senior financial executive he knew at 26 Google to find out whether their company had additional insight or any interest in studying large-27 scale evacuation planning. He had a series of conversations over several years that led to a project 28 with Google Research, which was looking into disaster assistance. 29 30 The City formed an internal team, which included representatives from Police, Fire, Public Works, 31 along with Traffic Consultant David Parisi, and Vice-Mayor McCauley, to discuss Mill Valley's 32 evacuation planning and response with Google Research. The initial meeting included a "table-33 top" evacuation exercise, which simulated a massive, rapidly spreading fire in Mill Valley, to 34 demonstrate the tools the City uses to manage such an event. 35 36 Evacuation Study: 37 Following a series of meetings and calls, Google Research committed resources to further study 38 the dynamics and timing involved in a city-wide evacuation. The group conducted a study of Mill 39 Valley and Paradise, which was then developed into an academic paper for publication in a highly 40 respected peer reviewed global technical journal, Transportation Research Interdisciplinary 41 Perspectives. The following is an abstract from the recently published paper, which can be found 42 at: https://www.sciencedirect.com/science/article/pii/S259019822030l214. 43 44 "Traffic evacuation plays a critical role in saving lives in devastating disasters such as 45 hurricanes, wildfires, floods, etc. An ability to evaluate evacuation plans for these rare 46 events, including identifying traffic flow bottlenecks, improving traffic management 47 policies, and understanding the robustness of the traffic management policy are critical 48 for emergency management. Given the rareness of such events and the corresponding 49 lack ofreal data, traffic simulation provides a flexible and versatile approach for such 50 scenarios, and furthermore allows dynamic interaction with the simulated evacuation. 51 In this paper, we build a traffic simulation pipeline to explore the above problems, 52 covering many aspects of evacuation, including map creation, demand generation, 53 vehicle behavior, bottleneck identification, traffic management policy improvement, 54 and results analysis. We apply the pipeline to two cases studies in California. The first 55 is Paradise, which was destroyed by a large wildfire in 2018 and experienced 56 catastrophic traffic jams during the evacuation. The second is Mill Valley, which has 57 high risk of wildfire and potential traffic issues since the city is situated in a narrow 58 valley." 59 60 The Google Research Group developed a detailed simulation of the City's 6000-plus households 61 attempting to leave town in their cars using home locations and road capacities under a variety of 62 conditions, including speed of notification, timing of departure, and other variables. Based on the 63 research and simulations, the Google Research Group further studied potential ways to improve 64 the speed of an evacuation plan, which are discussed below. The City's team could review the 65 draft document and offer comments before the paper was published. The team's review of 66 Google's simulation provided two critical insights. 67

68 The City's evacuation planning had previously considered the idea of converting East Blithedale 69 A venue to a contraflow ( opposite traffic direction) road in the event of an emergency with all 70 inbound and outbound lanes exiting out toward the freeway. The Google Research simulation 71 independently reached a similar conclusion and confirmed that this approach had the potential to 72 significantly decrease evacuation time. A quote from the paper, as follows. 73 74 "The new policy enlarges the network capacity by adding a reversed road and a 75 detoured local road, but still gets saturated during the peak. However, the jammed 76 condition ... does not last long. One hour later, the network is fully cleared ... The 77 traffic jam ... still remains in both the downtown area and the peripheral areas ( ... an 78 hour later if there is no change from normal traffic patterns). There is no real case 79 we can compare with, but the new evacuation policy shows remarkably 80 improvement in the simulation." 81 82 Following confirmation of the City's idea through the simulation, Staff is taking formal steps to 83 readily deploy equipment to execute this plan, as necessary, which is detailed further below in this 84 staff report. 85 86 The simulation also confirmed a second key hypothesis, that overall speed of evacuation is greatly 87 enhanced if each household uses one vehicle, instead of two, during a rapid city-wide evacuation. 88 The City will encourage this idea in its education and disaster notification strategies. 89 90 In response to observing the evacuation traffic simulations first-hand, the City team further 91 investigated an additional priority of preventing downstream backups on arterial roads, which 92 potentially delay evacuation timing for vehicles exiting from the canyon and hillside 93 neighborhoods. Vice Mayor McCauley described the approach as being like a crowded grocery 94 store opening more check-out stands to quickly clear a customer backup. 95 96 City staff estimated the number of vehicles that would likely be one the roadway during a stop-97 and-go backup of our two primary arterial exits: East Blithedale Avenue, from downtown to 98 Camino Alto, and Miller A venue, from downtown to Camino Alto. Staff then evaluated a plan to 99 direct traffic from these main arterial roads into Bayfront Park and the Tamalpais High School

100 athletic fields, which have already been identified as Community Refuge Areas (CRAs), to 101 potentially relieve gridlock and allow for additional upstream vehicles to move further away from 102 the constricted canyons and hillside areas with limited escape routes. Allowing upstream vehicles 103 to move more quickly onto Miller A venue and East Blithedale A venue has the potential to expedite 104 a full evacuation of the City, particularly if the greater regional area and/or local freeways are 105 impacted. 106 107 Google Research has indicated a willingness to further refine their simulation in the future to 108 address additional observations. For instance, the Google simulation model did not consider the 109 impacts of sheltering within the City, instead of exiting to the freeway. The simulations also 110 assumed normal background traffic at the freeway, which may not be the case. The distribution 111 and location of homes within our community could also be enhanced within the simulation. 112

113 Each emergency is unique, and our Police and Fire departments will have to make real-time 114 decisions based on evolving conditions. The information and additional preparation gathered 115 through this process will aid in their decision making. The City appreciates Google Research for 116 generously choosing to study Mill Valley for academic purposes and continuing to dialog with us. 117 The insights resulting from this simulation and the planning efforts are helping better prepare the I I 8 City for potential emergency evacuations. 119 120 This staff report will provide details of the preparations being considered at the mentioned sites. 121 Further efforts will enlighten what the City might expect in the event of an emergency evacuation, 122 and how we can better prepare for a safe and timely evacuation. 123 124 Discussion: 125 126 Vehicle Evacuation & Routing: As described above, the Google Research Evacuation Study 127 generated potential enhancements to our evacuation planning and preparedness, which included 128 options to convert a portion of East Blithedale A venue to a contraflow model and opening 129 Hamilton Drive to two-way traffic to allow additional outbound traffic. 130 131 East Blithedale Avenue Contraflow: Contraflow involves reversing the normal direction of 132 traffic on one or multiple lanes to increase traffic flow in the opposite direction. In this case, East 133 Blithedale Avenue (EBL) could be converted to allow two lanes outbound (east) from Camino 134 Alto all the way to US Highway 101. This means the current inbound single lane of EBL from 135 Ashford Avenue to Lomita Drive could be used as an additional outbound lane where the roadway 136 currently narrows. This would require re-routing of inbound traffic on EBL to Ashford/Lomita for 137 emergency traffic. The diversion of inbound traffic is not relevant to the evacuation calculations, 138 but an important element to the plan to have inbound capacity for emergency vehicles. The City 139 Manager has authorized the purchase of equipment necessary to convert EBL to contraflow. 140

Hamilton Drive Two-Way Configuration: Hamilton Drive is currently configured for inbound traffic only between Seaver Drive and the Public Safety Building (PSB). The roadway striping already allows for conversion to two-way traffic, which could be used to detour additional outbound traffic from EBL to Roque Moraes Drive, then to Hamilton Drive and on to Redwood Highway Frontage Road for additional freeway access. This configuration has been used several times in the past when EBL and Miller A venue are gridlocked due to traffic signal malfunctions. Inbound access would remain on Hamilton Drive for emergency vehicles stage at the PSB. The City already has a cargo trailer with equipment necessary to convert this section of roadway.

The Google Research Evacuation Study contemplated using Roque Moraes to Kipling Drive, then allowing traffic to rejoin EBL just prior to the US Highway 101 southbound ramp. Eliminating this option and using the additional freeway onramps accessible from Redwood Highway Frontage Road could provide additional outbound relief. Additional signage could be added to the current detour plan to discourage motorists from using Longfellow and Kipling, as the purpose of this detour would be routing traffic all the way to Redwood Highway Frontage Road.

Vehicle Staging Concept: The City team also surfaced the idea to potentially use Bayfront Park and the Tamalpais High School sports fields as temporary holding areas to potentially relieve gridlock and allow for additional upstream vehicles to move further away from the constricted canyons and hillside areas with limited escape routes. The city is considering adding more specific tactical planning to the general Community Refuge Area (CRA) strategy discussed below, that cities in Marin are using.

Staff estimates Bayfront Park at the eastern end of Sycamore A venue could be used as a temporary holding area for up to 1,000 vehicles. A rough calculation shows EBL holds 350-500 cars between Camino Alto and Throckmorton. Bayfront Park could be used to divert traffic from outbound EBL to Camino Alto to Sycamore A venue and into the park with the capacity to potentially clear EBL of slowed or gridlocked traffic at the time peak evacuation and allow additional vehicles to egress from the hillside areas on the north side ofEBL between downtown and Camino Alto.

177 Staff estimates Tamalpais High School sports fields could be used as a temporary holding area for 178 up to 1,500 vehicles. This additional space could be used to clear outbound traffic on Miller 179 Avenue and Camino Alto. 180 181

182 183 184 This project will require a fully developed traffic routing plan, associated signage, equipment 185 staging, along with community and staff training. It will also require improvements for access and 186 routing into the fields, as well as evaluation and cooperation with Tamalpais High School. 187 188 Developing this strategy of efficiently sheltering 2,500 cars at these two prepared locations, along 189 with the potential of other smaller downstream sites, could significantly improve the outcome of 190 6,000+ cars attempting to move to safety during a conflagration and evacuation. 191

192 Vehicle Staging Considerations: It is essential to understand the various elements of evacuation 193 when studying community evacuation, which includes: 194 • Incident detection time 195 • Response and decision time 196 • Community warning and notification time 197 • Community preparation time (leaving their residence) 198 • Network clearing time 199 • Total time phases add up the evacuation time. 200 201 No single element can be used to fully remedy traffic congestion and/or enhance evacuation times. 202 All phases must be considered, mitigated, and shortened in time duration to enable a successful 203 community evacuation. While traffic rerouting and network clearing could be enhanced, the Mill 204 Valley Emergency Preparedness Committee (EPC) has primarily focused on community warnings, 205 notification improvements, and evacuation preparedness. These elements have been prioritized 206 through 15 years of evacuation drills and countless other community education events. 207 208 The idea and concepts surrounding the use of vehicle staging areas, coupled with the Community 209 Refuge Areas, was brought before the EPC on November 12, 2020. Overall, the concept was 210 intriguing to the EPC, but there were identified concerns as well. This concept is designed to 211 remove vehicles from already clogged and stagnant roadways, such as EBL, Miller A venue, and 212 Camino Alto, and funnel these vehicles to designated staging areas to wait until the roadway 213 pressure has released. This also allows for more evacuees to escape the canyons and hillside areas 214 and move away from potential danger. 215 216 Depending on the scope of the incident, staffing, and controlling the vehicle staging areas could 217 potentially fall with allied law enforcement agencies, other City personnel, or Community 218 Emergency Response Team (CERT) members. Staff assigned to the vehicle staging areas would 219 need to systematically place drivers in predetermined parking positions to allow for maximum 220 vehicles, and then hold drivers until it is safe to return to the roadways to continue evacuation. The 221 EPC believes that a concept of this magnitude would require major planning, heavy staffing, 222 community education, and practice of concept on a large scale. 223 224 There were also concerns associated with having residents driving their vehicles onto unpaved 225 areas of Bayfront Park, adjacent to mud and water, during conditions of heavy smoke, low 226 visibility, and driver ability in an emergency. The use of existing parking lots that are already 227 marked, more familiar, and typically used by residents on a day-to-day basis could be used as an 228 additional option. The following potential locations should be explored. 229

263


Additionally, this concept would need further exploration and development to potentially be used during an emergency evacuation and could be further socialized and vetted during the 2021 City Evacuation Drill.

Community Refuge Areas: Community Refuge Areas (CRA) are pre-identified areas throughout the Mill Valley and Southern Marin region where residents can seek shelter from a fast-moving wildfire within their neighborhood. Widely considered as an area of last resort, CRA's provide community separation from fire and provide relative safety for 60 to 90 minutes until law enforcement provides direction. Typically, large, green open spaces like golf courses, parks, and ball fields, CRA's are provided as options when complete evacuation is not possible due to roadway inundation or blockages.

Evacuation Preparedness: Evacuation preparedness is an essential element necessary for a quick and efficient community evacuation. Residents and visitors who have prepared to evacuate with grab-and-go bags containing your "Top 1 O" check list will be effective at leaving quickly. Those who have a plan for evacuation, practiced the plan by knowing two ways from their homes, and selecting one vehicle for the evacuation will ease the traffic burden on Mill Valley's road network.

264 For more information, please go to: 265 https://www.cityofmillvalley.org/fire/emergency/mapinfo/evacuation mailer 2019 .htm 266 267 Emergency/ Evacuation Notifications: Mill Valley has 10 Fire Protection (Defense) Zones as 268 designated by the Mill Valley Fire Department/Southern Marin Fire District. The pre-identified 269 structure protection zones are reflected on the attached color-coded map (Attachment 1) and 270 corresponding street name chart (Attachment 2). Law enforcement will reference these 10 zones, 271 by name, when activating notifications and potential evacuations. The zones are georeferenced and 272 aligned with programs operated by the Marin County Sheriffs Office of Emergency Management. 273 Alerting programs and platforms familiar to Marin County residents include Alert Marin, Nixie, 274 siren speakers (LRAD), and social media outlets. 275 276 Alert Marin: electronic emergency notification system by telephone that will be used when action 277 is needed at a specific address or neighborhood. This can include information on flooding, 278 wildfues, and evacuations with life safety implications. 279 280 Nixie: electronic emergency notification that utilizes text and email to push information in a 281 specific zip code. 282 283 Twitter: web and application based social media network that provides general alerts and updates.

284 285 Hi-Lo Sirens: In June 2019, the Mill Valley Police Department was granted a permit from the 286 California Highway Patrol to use the "Hi-Lo" siren for evacuation and emergency alerting 287 notifications. The Hi-Lo siren was used by Sonoma County law enforcement agencies during the 288 Tubbs and Nuns Fire to alert residents to immediately evacuate. The siren can be used along with 289 mass messaging to alert residents of the need to evacuate. The siren uses a different pitch and 290 cadence than other sirens used for typical emergency responses. The Hi-Lo siren is currently used 291 by several other Marin County law enforcement agencies. By having all MVPD patrol vehicles 292 outfitted with this evacuation siren, we can assist allied agencies with evacuations as well as call 293 on others in the immediate area for their assistance.

294 295 In August of 2020, the State Assembly approved SB 909 which authorizes municipalities 296 tluoughout the state to use the distinctive alerts in emergency vehicles during evacuations. This 297 legislation authorized the use of the hi-lo siren "solely for the purpose of notifying the public of 298 an immediate evacuation in case of an emergency," not for regular emergencies or code-three calls. 299 300 LRAD Update: Following the 2017 Sonoma and Napa conflagrations, which have now been 301 eclipsed by the mega-fires in Shasta and Butte Counties, we have been actively evaluating and 302 implementing programs and processes to ensure our lowest overall community risk possible. Our 303 evaluation has concluded that many City of Mill Valley processes align with industry best practices 304 and identified several gap areas needing attention. The result has been the development of six Fire 305 Prevention Initiatives endorsed by the City Council on February 5, 2018, titled: Fire Preparedness 306 and Prevention Overview and Recommendations. 307 • Initiative 1 - Building Codes, Standards, and Structural Ignitability: 308 • Initiative 2 - Hazardous Fuel Reduction 309 • Initiative 3 -Access and Evacuation Concepts 310 • Initiative 4 - Public Education 311 • Initiative 5 - Communications 312 • Initiative 6- Staff training 313 314 Although there are many scenarios the LRAD could help resolve, we see the use of LRAD directed 315 toward disaster communications. During wildland fire conflagrations and other dangerous 316 incidents, a few individuals or several thousand people may be affected. LRAD systems effectively 317 communicate warnings, instructions, and notifications throughout incident sites and over vast areas 318 during life-threatening events. 319 320 Warn & Notify: 321 • Notify everyone in affected areas simultaneously. 322 • Quickly establish and enforce restricted areas. 323 • Warn of blocked evacuation routes. 324 Instruct & Direct: 325 • Provide stay/evacuate, safe exit routes, quickly clear hot zones. 326 • Communicate concise and unambiguous messages to assist with DECON procedures. 327 328 Currently, the City of Mill Valley provides emergency notifications for wildland fire by various 329 methods to include approaches surrounding phone calls, text messages, and emails, as well as 330 redundant systems such as emergency sirens. The installation of the LRAD system which occurred 331 the summer of 2019 has enhanced our emergent community communications. The system1s 332 installation and operation included several site visits from LRAD subject matter experts and 333 various meetings with the Marin County Office of Emergency Services. California's recent 334 devastating fires to include the: Carr Fire (Shasta County), Camp Fire (Butte County), and the 335 Tubbs Fire (Napa/Sonoma County), resulted in community fatalities, and all suffered shortfalls in 336 emergency notification and communications. The emergency notification process involves many 337 methods that range from low tech - police officers evacuating residents' door to door and high-338 tech solutions such as the wireless emergency alerts (WEA) and now potentially the LRAD

10


339 technology. Given that most all notification systems require an element of infrastructure to 340 operate, sufficient redundancy exists with LRAD's battery backup systems and satellite downlinks. 341 342 LRAD System Performance & Proposed Improvements: Installation of the system and sound 343 coverage was based on an LRAD engineering review (site inspection) and recommendations. The 344 utilization of current infrastructure (the old siren system) was selected for use. This was deemed 345 the minimum viable product to provide an immediate communications enhancement to the 346 community. The new LRAD system has been operational for over a year and feedback through an 347 informal survey has been mixed. Many in the community can hear the alert tones and voice 348 message while others said they could hear the alert tone but found the voice message to be muffled 349 or unclear. Others reported not hearing either the alert tone or voice message but many of them 350 could not hear the previous siren system either. 351 3 52 Based on the information provided through a survey and a new evaluation, we propose additional 353 siren locations throughout Mill Valley to enhance coverage and improve the clarity of alert tones 354 and voice messages for more residents. The proposal adds two sirens to the system to include a 355 SASM location that will cover Seaver Drive and the surrounding area, and a shared (Southern 356 Marin Fire Protection District) site located at the Edgewood Reservoir. Additional horns will be 357 added to the Ralston White site to enhance coverage of W. Blithedale, as well as additional 358 directional horns to the Cascade location to enhance sound up towards Edgewood, Rose, and 359 Marion residents. The cost of upgrades is estimated at $300,000, which can be paid for through 360 local mitigation or core function funds provided through the Marin Wildfire Prevention Authority. 361 362 It should be understood by the community that the LRAD installation enhancements and 363 operations represent one available option for emergency communications. The experiences of all 364 community members may vary by virtue of proximity and geography between the resident and 365 any LRAD location. 366 367 Next Steps: 368 369 Zonehaven: Recently, the Marin Wildfire Prevention Authority, under direction of Executive 370 Director Mark Brown, secured a multi-year commitment with the company Zonehaven (An 3 71 evacuation management platform - Intelligent Evacuation Zones, Hyperlocal Scenario Planning, 3 72 Rapid Hazard Modeling Program) that is being made available to Marin Fire and Law Enforcement 373 agencies. Zonehaven is currently in-use by Sonoma County, San Mateo County, and Santa Cruz 374 County. These agencies utilized the capabilities and tools of Zonehaven during the 2020 fires 375 (Lightning complex fires). It was critically helpful in evacuating residents from the Glass Fire 376 among others in the North Bay. 377 378 Zonehaven is a tool to assist in managing evacuations by tapping into and providing evacuation 379 traffic, mapping, and communication for Fire and Law as well as outward facing modules for the 3 80 public. This is a collaborative platform for first responders and the public to plan and react during 381 an incident. Zonehaven is currently working with companies such as Google, AirBnB, and Waze 382 to develop the most real and in-time evacuation messaging and traffic plans prior to and during an 383 active incident.

11


384 385 Zonehaven will help provide agencies with the tools to pre-identify potential traffic issues, tap into 386 universal messaging, and help provide a realistic timeline of events and spread based on weather 387 patterns and input from first responders. Marin County Fire Agencies have been in conversations 388 with Zonehaven since late 2018, and the Mill Valley Police Department did attend their first 389 product introductory and kick-off meeting on February 17, 2021. 390 391 The Marin Wildfire Prevention Authority is also investigating a larger study of the entire county 392 that seeks to identify problem areas such as, road width restrictions, challenging intersections, high 393 use confluence areas. The information garnered will be utilized for future infrastructure projects 394 and to assist incident commanders with the timing of notifications. 395 396 Community Evacuation Drills: Currently both Staff and the Mill Valley EPC are evaluating the 397 viability of conducting an in-person community evacuation event for 2021. The continued 398 presence of COVID-19 and shelter in place orders have given pause to future event planning. Two 399 questions are under consideration by Staff and the EPC: 400 1. Can/Should we conduct an in-person evacuation drill safely in the presence of a pandemic? 401 2. Will the community members participate in an evacuation drill within their neighborhood 402 in the presence of a pandemic? 403 3. Could the city simulate the impacts of clearing EBL and Miller cars this summer into 404 Bayfront park and Tamalpais High School if the infrastructure and planning efforts are 405 complete and everyone stays in their vehicles during the drill? 406 407 To answer the questions, staff has reached out to Marin County Health and Human Services (HHS) 408 for advice on hosting an outdoors event. Marin HHS advised that these types of events can be 409 done safely outdoors with appropriate social distancing, facial coverings and hand washing 410 stations. It is largely believed that residents will not participate in an evacuation drill given the 411 presence of the pandemic suggesting that the City should consider providing neighborhood 412 discussion and forums remotely to enable the dialog regarding current evacuation concepts. 413 414 Fiscal Impact: The fiscal impacts on preparing for evacuations are approximate based on supplies 415 needed for specific contraflow options and previously planned route expansions. The equipment 416 needed for the EBL contraflow and Miller Avenue two-lane configurations is estimated at $15,000 417 and has already been authorized by the City Manager. 418 419 Further study is needed to identify costs related to converting Community Refuge Areas into 420 potential Vehicle Staging Areas. It will be important to incorporate traffic pattern setup and 421 breakdown with any purchased supplied and equipment to understand roles, responsibilities, and 422 capabilities of staff and allied agencies. Staff will explore incorporating these trial runs into 423 upcoming Mill Valley evacuation drills. 424 425 Attachments: 426 1. Mill Valley Structure Protections Zones (Map) 427 2.
