Meeting Date:05/15/2025 Requested by: Dennis Roberts, Public Works Submitted By:Dennis Roberts, Public Works SUBJECT: PRESENTATION AND DISCUSSION OF ORO VALLEY MONSOON PREPAREDNESS RECOMMENDATION: For informational purposes only. EXECUTIVE SUMMARY: As the summer rainy season approaches, the Town of Oro Valley Stormwater Utility is committed to promoting monsoon awareness and safety. While these seasonal storms offer a refreshing break from the heat, they also bring heavy rainfall, powerful lightning, strong winds, and dust, creating the potential for dangerous flash floods. Flash flooding remains the leading weather-related cause of death in the United States, with nearly half of these fatalities involving vehicles caught in rising waters. In anticipation of the upcoming monsoon season, the Oro Valley Stormwater Utility has proactively engaged in outreach efforts, collaborating with partnering agencies, residents, and internal staff. Through these coordinated initiatives, we aim to enhance preparedness and safety, ensuring that our community can enjoy the monsoon season while minimizing risks. By staying informed and taking precautionary measures, we can make this summer’s rainy season both enjoyable and secure for everyone.

Call us at 520-229-4850 or email PW@orovalleyaz.gov. DRIVING DURING MONSOON SEASON Thunderstorms, thick dust storms and flash floods are all very common during Southern Arizona’s monsoon season. They also create hazardous conditions for motorists. Given the many washes and hills located within Oro Valley, it is critical to reacquaint ourselves with how best to handle adverse weather conditions while on the road. Heavy Rain •Ensure a safe following distance between cars—four seconds is ideal for stormy weather. Tires lose traction on wet surfaces, which can make it harder to stop suddenly. •Watch for large vehicles traveling through puddles. They can throw blinding sheets of water across your windshield. •If you begin to hydroplane, remove your foot from the gas pedal until you regain traction. Do not brake suddenly. If you are sliding, turn the wheel in the direction of the slide to straighten out. Dust Storms •Avoid driving during dust storms. •Turn on your headlights and slow to a reasonable speed. Never stop on the pavement during a dust storm. •If the storm becomes too severe, pull off the road as far to the right as possible, turn off all lights and set the parking brake. • Do not turn on your hazards or keep your foot on the brake. Other cars may think you are still in motion and try to follow you. Arizona Stupid Motorist Law Many roads which flood during monsoon season have roadblocks or barriers to keep drivers from entering. These signs and barriers must be adhered to, otherwise you could be required to pay for emergency services should you become stuck. Per Arizona State Law A.R.S 28-910, any motorist who drives past a safety roadblock into a flooded wash or channel may be liable for the expense of emergency rescue services (up to $2,000). EMERGENCY PREPAREDNESS The severe storms brought on by monsoon season can lead to a number of different emergencies, from power outages to flash floods. It is vital that all households prepare a contingency plan in case of an emergency. Emergency Kits Each household should put together an emergency kit. These kits should reflect the size of the household and should be maintained and updated regularly. Formulate an Emergency Plan •Identify meeting locations both inside and outside of the neighborhood for your family/household. •Identify non-local emergency locations where you will meet if the inside/outside neighborhood meeting locations are not accessible. This can be an out-of-town friend’s house, shelter, or hotel. •Name an out-of-town contact. This can be someone who lives beyond the immediate area who will serve as the main point of communication for your household. This person is particularly important should your household get split up in an emergency. •Make sure everyone in your household is familiar with alternative routes through town. The route you usually take could become blocked, so it is important to know the area. Evacuation Though rare, there is a possibility that during monsoon weather conditions, evacuations could become necessary. Follow the 5 P’s of Immediate Evacuation in order to be prepared and remain safe. •People and Pets and other livestock •Papers and important documents •Prescriptions like medications, eyeglasses, hearing aids, etc. •Pictures - irreplaceable memories •Personal computer and information on hard drives or disks Oro Valley Monsoon Preparedness Guide Town of Oro Valley Stormwater Utility WHAT IS A MONSOON? Every summer, Southern Arizona experiences a weather phenomenon known as monsoon season. From approximately June 15 to September 30, monsoon season is marked by intense rain, lightning shows and thick dust storms. While the rain provides a welcome relief from the usual arid heat, the high winds and thunderstorms that accompany this weather shift often create treacherous conditions. Dust storms and flash floods are prevalent during this time of year, making it exceedingly important to be prepared. STORMWATER UTILITY The Arizona monsoons provide unique and complex challenges for the Town of Oro Valley, which is why the Stormwater Utility was developed in 2008. This division of the Town’s Public Works Department was established to protect Oro Valley’s working and natural environments before, during and after the occurrence of storm events. Some activities where you can see Stormwater Utility in action include, but are not limited to:street sweeping, storm cleanup, drainage channel vegetation maintenance, storm system inspections, and Adopt-A-Wash Program. The Stormwater Utility is an excellent resource for information about floodplains, stormwater quality, and illicit discharge control. Information provided by TEP at tep.com/monsoon-safety Monsoon Safety 10 Safety Tips While short-term outages are an inconvenience, extended outages from monsoon storm damage can have a larger impact. Just as Tucson Electric Power prepares all year long for storm season by fortifying our electrical system, customers also can prepare to ensure they’re safe and sound if the lights go out. Here are 10 steps to take so you’re ready, no matter what the weather brings: 1. Ready an emergency kit Long before our first severe storm, assemble an emergency kit with essential items your family will need. Your kit should contain a battery-powered radio, flashlights, fresh batteries, a first aid kit, nonperishable food and drinking water– one gallon a day for each person in the household. And don’t forget that your pets also need food and fresh water. Good nonperishable food choices include crackers, dried fruit or trail mix, beef jerky, canned or pouches of chicken or tuna and granola bars, all of which have a longer shelf life. To avoid stumbling around in the dark and possibly hurting yourself, have several light sources, such as a battery-powered flashlight and lantern. Don’t use candles, which can tip over and start a fire. “If you have an emergency kit already, this is the perfect time to update items by checking expiration dates on food and the power levels of batteries,” said Brian Herman, TEP’s Director of Corporate Safety. 2. Watch the weather Follow weather forecasts on the TEP mobile app or tune into local radio and TV stations so that you’ll be aware if severe weather is developing and can prepare. Before storms hit, secure patio furniture and umbrellas and loose objects to prevent their damage and flying debris. Sign up for free weather alerts from NOAA, the National Weather Service and Pima County Emergency Management to stay informed of severe weather warnings. 3. Have backup communications If landline phones are out or your home’s wireless phone needs electricity, your cell phone may be your only communication tool – until the battery runs out of juice. Investing in a solar cell phone charger can help you recharge and make calls in an emergency. Some devices store energy, while others can only provide a charge if the sun is shining on the solar cell. Most devices cost less than $50. To extend your phone’s battery life, turn off background applications, notifications and streaming service or just power it down until you need to use it. In a pinch, use your vehicle’s power outlet with your phone charger to boost your battery or to power other electronics. 4. Turn off your AC TEP recommends that you turn off your air conditioner during a power outage. Why? Well, it’s not doing you any good without electricity anyway … but the real reason has to do with what happens when the power comes back on. When service is restored to a section of our grid that suffered an outage during hot weather, every air conditioner in that area that wasn’t turned off starts up at the same time, trying to get all those warm homes and business back to a comfortable temperature. The problem is that AC units require additional power at the moment they start – much more than they use while operating. The combine d impact of hundreds or thousands of AC units starting up at the exact same moment can trigger reliability problems that cause another outage or even damage your AC unit. Turning off the AC helps protect your unit and our grid. It also provides an opportunity to burn a few extra calories walking back to the thermostat to turn it back on after service is restored. 5. Use surge protectors Lightning strikes during a monsoon storm can sometimes cause power surges that can damage electronics plugged into outlets. Using smart power or surge strips for your television, gaming station and other electronics will protect them from these spikes. You’ll also be protected from the impact that phantom energy can have on your electric bill. 6. Stay away from downed power lines Downed power lines can still be energized and deadly, even if they look harmless. Always stay far away from downed lines, call 911 to report them and keep others away from the area. Never drive over a downed power line or attempt to get out of your car if a power line has fallen on it. Call 911 and wait for help. If you must get out of the vehicle for some reason, here’s how to do that safely: “Open your door and jump out and away from the vehicle being careful not to touch the car and the ground at the same time,” advised Roger Hall, TEP Manager of Transmission & Distribution. “Both feet need to be touching and together when you land or shuffle with your feet close together until you are at least 20 feet away from the vehicle.” 7. Stay cool in extreme heat Outages that occur during extreme heat can pose a real health concern without air conditioning. Drink plenty of water to stay hydrated and wear loose clothing made of a breathable fabric. Consider buying a few battery-powered fans, which are remarkably effective at moving air to make it feel cooler. Using gel-filled cooling neck wraps also can help lower your body temperature. Simply wet the wrap and slip it around your neck for a cooling effect. In extended outages, check TEP’s outage web page for updates, details about community cooling centers that may have been set up and other services available in affected areas. 8. Minimize food loss Keeping the refrigerator and freezer closed will safely keep food cold for about four hours. Adding bags of ice also will extend the cooling time. Once the freezer begins to warm, transfer frozen foods into a cooler with ice. If the temperature of the foo d is higher than 40 degrees for two or more hours, it’s best to throw out the food rather than risk getting sick. Here’s a trick to know whether your food may have spoiled during an extended outage. Place a cup of water in your freezer. After the water freezes, place a coin on top of the ice. If you later find that coin below the ice’s surface, you’ll know the food in your freezer and fridge thawed at some point and the food is likely unsafe to consume. When in doubt, throw it out! Something you can do before an outage is to fill milk jugs with fresh water and place them in your freezer. This will not only help keep your food cold during an outage, but they also can be thawed to provide fresh drinking water. 9. Know your medical options If you rely on an electronic medical device or have refrigerated medications, talk with your medical provider about having a power outage plan. Find out how long your medication can be stored at higher temperatures and get specific guidance for any medications that are critical for life. Possible options might be having a backup generator to power your refrigerator or medical device, using an ice chest for temporary storage or going to the home of a friend who has power. TEP customers with medical devices that require electricity are encouraged to enroll in our Medical Device Alert program. Customers in this program are kept informed about the status of service interruptions and the estimated time of restoration. 10. Prevent electrical hazards during flooding Monsoon storms often are accompanied by heavy rains and flooding. “Never use electric appliances or touch electric wires, switches or fuses when you're wet or when you're standing in water,” Hall suggested. “Keep electric tools and equipment at least 10 feet away from wet surfaces and don’t use electric yard tools if it's raining or the ground is wet. Electricity and water don’t mix well.” Register for CodeRED orovalleyaz.gov/Government/Departments/Town-Managers- Office/Services/Register-for-CodeRED CodeRED is a FREE emergency notification service provided to all residents within Oro Valley that will notify you of emergency information through phone calls, text messages, emails and social media.

Town of Oro Valley Definition: A monsoon is a seasonal wind shift that creates alternating wet and dry periods, driven by temperature differences between land and ocean What are Monsoons? The Hazards Oro Valley Residents Face How do Monsoons Impact Oro Valley? While the rain provides a welcome relief from the usual arid heat, the high winds and thunderstorms that accompany this weather shift often create treacherous conditions. •Heavy rainfall leading to flash floods •Dust storms reducing visibility •Lightning risks during storms. Safe Driving in Monsoon Conditions Heavy Rainfall •Flooded Roads •Maintain a Safe Following Distance. Keep at least four seconds of space between you and the car ahead. Wet roads reduce traction and increase stopping time. •Watch for Water Splash Hazard •Large vehicles can create blinding sheets of water, reduce visibility. Stay cautious near puddles •Hydroplane Recovery Tips •If you start to hydroplane, lift your foot off the gas to regain traction. •Avoid sudden braking – it can make skidding worse. •If sliding, turn the wheel in the direction of the slide to straighten out safely. •Heavy rainfall can turn dry washes into dangerous flood zones. •Flooded roads can sweep away vehicles—"Turn Around, Don't Drown!"
