BSK: Downtown Merced Revitalization

BSK helps revamp historical buildings in downtown Merced.

Revamp on historical buildings in downtown Merced.

BSK helps downtown Merced revitalize historical buildings. Three of Merced’s oldest buildings are receiving a face lift in hopes of bringing downtown Merced back to life. Downtown Merced has been under construction over the past year on Tioga Hotel, El Capitan Hotel, and the Mainzer Theatre. Not only are these three historical sites some of the oldest buildings in Merced, built as early as 1920’s, they also have noteworthy historical pasts. The goal of this project is to renovate these notorious sites, while still maintaining some historical integrity.

BSK Associates has played a key role in the renovations of each of these buildings. After BSK’s initial Geotechnical Engineering Investigation, South Valley Regional Manager, On Man Lau, PE, GE, was able to reduce the size of the micropiles. This reduction saved the developer thousands of dollars towards the renovations.

BSK: Downtown Merced Revitalization

All three renovations are still in progress. However, we are excited to announce the Tioga is nearing completion. The El Capitan Hotel and Mainzer Theater are also well on their way.

The Tioga Hotel becomes Luxury Apartments

Tioga Hotel, Downtown Merced Revitalization.

The Tioga Hotel is one of the oldest and largest buildings in the City of Merced. Built in 1928, the Tioga was home to Merced’s first neon sign, was a key player in the wartime efforts during World War II, and attracted numerous notable figures and royalty from across the world, including Calvin Coolidge, Eleanor Roosevelt, Marilyn Monroe, and John Kennedy. The National Register of Historical Places inducted the Tioga in 1980. Due to its prestigious history it was important to all those involved to preserve as much of the building as possible, while upgrading the structure to today’s safety standards.

BSK had the opportunity of performing field exploration on the Tioga; designing micropiles for a seismic retrofit on the existing six story reinforced concrete structure. Furthermore, we performed materials testing and inspection on the Tioga including but not limited to:

  • Drilled Pier Soils Observations

    Tioga Hotel. Downtown Merced Revitalization.

  • Reinforced Concrete Inspections
  • Concrete Sampling and Testing
  • Post Installed Anchor Inspections
  • Shop and Field Welding Inspections
  • High Strength Bolting Inspections
  • Epoxy Rebar Inspections
  • Shear wall nailing Inspections
  • Wood Moisture Testing

Features include; studios, one-and two-bedroom apartments, and penthouse apartments. The lobby will feature social work-spaces, a fitness center, and private conference and event rooms. There are also plans to include a retail area on the street level space.

El Capitan Hotel Renovations

El Capitan is another historic remodel for the City of Merced. The original EL Capitan was Merced’s first hotel, built in 1872, the same year the City of Merced was established. Unfortunately, in 1931 the hotel burnt, but it was remodeled and has been left as it is since 1936.

As with the Tioga Hotel, BSK has helped with the renovations on El Capitan from the ground up,  from performing Ultrasonic Testing on the primary metal structure of the building in local weld shops, to being on the El Capitan job site, conducting Reinforced Concrete Inspection.

Tioga Hotel features 114 rooms restored to encompass the original feel of the hotel and honor the historic El Capitan as the town’s first railroad depot.  The space will also feature a restaurant, a café, and an amazing courtyard lounge.

The Mainzer Theater

The Mainzer Theatre revamp in Downtown Merced.

Although construction on this building originally began in the 1920’s, the Mainzer Theatre did not open its doors until Halloween, October 31st, of 1931. The Mainzer Theatre is one of the most recognized landmarks in Merced. Originally built by famous architects from San Francisco, the Reid Brothers. The Spanish Courtyard design was very unique. According to the Merced Theatre Foundation, which was responsible for the initial restoration of the building in 2012, “Patrons that visited the theatre believed that there were people living in the windows of the courtyard”. The Mainzer Theatre has been a special place for those of Merced, from school graduations and dance performances, to weddings, and of course movies; the theatre has been visited by many. Once again because of its rich history it was important to keep the historical feel on this project.

Additionally, BSK was asked to provide our services for the Mainzer Theatre. Some of the work we will be conducting includes:

  • Soils Observations and Compaction Testing.
  • Reinforced Concrete Inspections.
  • Concrete Sampling and Testing.
  • Post Installed Anchor Inspections.
  • Shop Welding Inspections.

Upon completion The Mainzer Theatre will have 4 bowling lanes, a restaurant, a stage, movie theater, and possibly a bar. Renovations are not scheduled to be completed until late 2020. However, they are already well into renovations.

 

 

 

Lastly, Mainzer Theatre. Merced Revamp.

Special Thanks

The downtown revamp has been a very rewarding project for BSK. We thrive on being a part of a project that truly makes a difference in the community.

Lastly, we’d like to give a special thanks to all of our BSK employees and our client!

First Triathlon Experience

First Triathlon Experience

First Triathlon Experience By: BSK Associates, South Valley Regional Manager, On Man Lau, PE, GE.

First Triathlon Experience written by BSK, South Valley Regional Manager, On Man Lau, PE, GE. featuring Malibu Triathlon experience.

 

Conquering the Triathlon Fear

This past September 26th, 2021, I had my first triathlon experience in Malibu, CA. The race included 0.5 mile of open water swimming in the Ocean, 17 miles of cycling, and 4 miles of running. The idea of entering a triathlon has always been on my bucket list. However, I am not a strong swimmer, and had never swam in open water. As with many of my excursions, this experience was the result of a challenge from my brother.

Once I decided to enter, I knew I had to focus my training on my weakest element. My goal is to overcome my fear of swimming, and build my endurance for the other portions of the race. In order to accomplish swimming a half mile distance in open water, I needed to focus on proper technique. I was lucky to connect with several experienced swimmers at the gym, and they all gave me valuable pointers and feedback. Even though I was only able to swim a couple of laps at the time, the swimmers I met during my daily training encouraged and energized me to push through and persist. In addition, YouTube also provided me with valuable tips from professional triathletes and swimming enthusiasts. Within three months, I was able to complete thirty laps at the gym without stopping!

Gradually, I began to believe that I could complete the triathlon. This race was an opportunity to face my lifelong fear of water, and for the first time, I felt confident that I could overcome!

The Triathlon Experience

On the long awaited day of the triathlon, the excitement and overall exuberant energy at the event was palpable. The thrill and anticipation of it all was made more meaningful by the attendance of all the families and supporters of the participants. There seemed to be endless poster signs from loved ones. I would soon realize how important these shows of affections were, as I would look for, and locate my family throughout the race.

The first leg of the triathlon requires the athletes to swim past the waves before moving on to the half mile required distance. It was definitely discouraging to see many young athletic swimmers struggling to get through the waves before our turn to start. As luck would have it, just prior to my group’s start to go into the water, the DJ played the theme song from Rocky, as I had requested earlier. The lively music was just what I needed to propel myself into the task at hand.

The Triathlon Struggle

As I fought with the waves to begin swimming, the reality of the open water was a shock to my system. Due to my inexperience, I inadvertently swallowed excessive amounts of salt water, and the view of the vast ocean was overwhelming. As I began to panic, a nearby lifeguard, Joe, came to my rescue. While I took respite on his floater, Joe offered some reassurance, “On Man, you still have a long way to swim…there’s no shame in quitting this part of the race…”.

My mind absorbed Joe’s advice. for a split second, I contemplated quitting while starring at the distance still to swim. However, I envisioned the looks of support and pride in my family’s eyes as they waited with excitement for me. Just as I can always count on their support in everything I do, I knew without a doubt that they have confidence in my ability to overcome my fears and conquer the quest that awaits me.

The Triathlon Reward

In an instant, I was able to renew my determination, and pushed forward to continue on. Just as the experts predicted, swimming proved to be the most difficult portion of the triathlon. Once completed, the burst of endorphins enabled me to maintain a study pace during the cycling and running components. Each time I caught a glimpse of my cheering family throughout the race, the love I felt from them provided wind on my back to carry me through.

What did I learn from participating my first triathlon experience at the 2021 Malibu Triathlon?

I learned the importance of consistent training to prepare for physical challenges. On the other hand, mental challenges are harder to overcome. For me, the defining factor to prevail over my mental obstacles were the support of my family. This experience has provided me the life lessons of importance of unconditional love and support. It has also taught me to be courageous to face our fears for the benefit of personal growth.

BSK Associates & PFAS Testing

/in /by

BSK Associates & PFAS Testing

 

What Are PFAS?

BSK Associates & PFAS Testing.

BSK Associates & PFAS Testing.

PFAS are man-made chemicals that include Perfluorooctanoic acid (PFOA), Perfluorooctanesulfonic acid (PFOS), GenX, and several additional chemicals. In fact, PFAS are made up of more than 3,000 man-made chemicals that are largely unregulated.

The U.S. began manufacturing these chemicals during the 1940’s. In 2006, the EPA launched the PFOA Stewardship Program which eliminated the use of several PFAS chemicals. Unfortunately, the U.S. still receives these PFAS compounds from imported goods from around the world.

PFAS are a concern because they do not break down and therefore bio accumulate over time. Furthermore, food, household products, animals, drinking water, and humans have all tested positive for PFAS. In fact, research has indicated that most people have detectable amounts of PFAS in their blood. Additionally, it is believed that everyone, even those who have not consumed drinking water that has been contaminated, will have some exposure to PFAS during their lifetime.

PFAS exposure can lead to many adverse health effects in humans including (but not limited to) thyroid hormone disruption, liver and kidney toxicity,  reproductive system and developmental damage, low infant birth weights, harmful effects on the immune system, and several different forms of cancer.

What can be done?

The US Environmental Protection Agency (EPA) and the Agency for Toxic Substances and Disease Registry (ATSDR) have issued exposure limits for PFAS in our drinking water.  February 6, 2020, the California State Water Resources Control Board announced that it will set new response levels (RLs) of 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. Previously, the RL was 70 ppt for the total combined concentration of PFOA and PFOS. California has established Notification Levels of 6.5 ppt for PFOS and 5.1 ppt for PFOA in drinking water.

The California State Water Board has already started PFAS testing on 30 airports, and nearly 200 landfills. Recently they requested testing at chrome plating facilities. In addition, the California State Water Board stated they will be requiring other potential PFAS sources to begin testing soon. Although these compounds are not currently fully regulated, it is believed they will be soon. In a release issued by the State Water Board they encouraged public water systems to test for possible contamination.

 

Why BSK Associates?

Experience, Knowledge, Volume, and Quality.

BSK Associates & PFAS Testing.

BSK Associates & PFAS Testing.

BSK has abundant sample capacity and can add to that capacity quickly.

We were one of the first labs to receive accreditation for testing in California. Furthermore, we have performed PFAS analyses for over 6 years. Subsequently, our laboratory completed thousands of PFAS analyses throughout the U.S. while participating in the EPA’s UCMR3 monitoring program. Therefore, BSK is well versed in reporting and regulatory quality requirements needed for these analytes.

BSK is accredited by the National Environmental Laboratory Accreditation Program (NELAP) and the California Environmental Laboratory Accreditation Program (CA ELAP) for all 18 PFAS compounds in drinking water by EPA’s 537.1 methodology.

Unlike other labs, we do PFAS sampling according to California State PFAS sampling guidelines. Collection of representative samples for PFAS analysis requires stringent Quality Assurance/Quality Control (QA/QX) measures to prevent sample cross-contamination due to the prevalence of these compounds in the environment. and the opportunity for contamination. BSK Associates can be your one stop shop, rather than having to hire another company for state testing needs.

It is important to be proactive, not only to protect your water system, but to protect the community in which you live. If you think you may have PFAS in your water system begin testing now.

BSK: Understanding Deep Foundations

/in /by

BSK: Understanding Deep Foundations

 What are Deep Foundations?

Deep foundations are a type of foundation that is used to transfer building loads further down the earth to utilize stable soil. This process is utilized when the existing soil is not stable enough to handle a foundation.

Deep foundations are essential for safety and maintaining the integrity of a building. Especially in California where we have liquification issues within our soil. Proper use of deep foundations will keep a building erect during an earthquake and prevent a structure from collapsing under duress.

Why use a Deep Foundation?

There are several reasons why you would want to use a deep foundation for the integrity of a structure. However, the main reasons would include weak soils, compromised soils, undocumented fills, and liquification.

Weak Soils: Essentially, weak soils is a term used when the existing soils could possibly fail if a shallow foundation were to be used.

Compressible Soils:  These are the soils that have the capability to decrease in volume; soil densification. Basically, when a structure is placed on compressible soil, without deep foundations, over time the soil will compress and pull down.

Undocumented Soil: This term is used when we do not know the stability of the soil.

Liquification: Soil liquification occurs when saturated soil becomes loses strength, usually in an earthquake. Basically, what was solid becomes liquid.

Types of Deep Foundations

There are two main types of Deep foundations; Driven Piles and Drilled Piers. A driven pile is driven into the ground, as you would imagine a nail being driven into a wall with a hammer. In essence, the pile is driven into the earth with a strong hammer. Moreover, with drilled piers, a hole is drilled, a cage is installed, and the hole is filled with concrete.

There are several types of driven piles and drilled piers, there are also specialty piles, such as micro piles.

Driven Piles

Driven Piles usually consist of; Timber Piles, Concrete Piles, Steel Piles.

Timber Piles would usually be used in a marine type environment. They usually last around 30 years and typically support between 15 to 20 tons.

Concrete Piles can be pre-cast or cast-in-place. They are usually reinforced with rebar to prevent breakage. Concrete piles are often used to support buildings that are very heavy; such as a high-rise structure.

There are two types of steel piles; steel H piles and steel pipe piles. H piles are solid piles and often used in commercial construction for bridges and large buildings. Steel piles are often used as an interlocking unit with other sources.

Drilled Piers  

Drilled Piers include Augercast Piers, Helical Piers. While Augercast piers are drilled holes filled with concrete and rebar a helical pier is twisted in and used to lift things up. Often you will see the use of helical piers in situations where foundations need repairs.

Specialty Piles  

In addition to the typical piles and piers referenced above there are several specialty piles that can be used. One of the most popular being Micro piles. Micro piles are usually used for underpinning and are extremely useful in areas that have limited access. They can also be a very cost-effective way to stabilize the foundation. To learn more about deep foundations check out the Deep Foundations Institute.

Soil Compaction Testing

/2 Comments/in , /by

Soil Compaction Testing

nuclear density gauge test

Soil Compaction Testing is a crucial step in the construction process. Ground that has not been properly compacted can be detrimental to the structural integrity of buildings, retaining structures, roads and pavements, just to name a few. Essentially, proper soil integrity could make or break your structure. Since soils are so critical to a structures reliability you will find that soil compaction testing is required most cases. For instance, most regulatory agencies such as, the Department of Transportation and American Society for Testing and Materials all require laboratory testing. Additionally, you will find that the California and Uniform Building Codes, the geotechnical engineer, and structural engineers will also require soil compaction testing.

Why Compaction Testing is Important

There is a very good reason for all the necessity. Basically, if soil tests are not conducted you risk shifting, cracking, and even the collapse of your building. Roadways could also result in disaster by cracking, sagging, potholes, or even sinkholes. In the end, it’s vital for the success of your structure to ensure you have reliable soil compaction testing. Moreover, having a company that has a seasoned and knowledgeable staff, as well as testing facility, is critical. Not only will a more experienced staff save you time, it will also save you money.

How soil Compaction Testing Works

A soil compaction test begins with samples. After excavation a field technician will collect soil samples. An experienced field technician will gather samples from several locations to attain representative samples of various soil types that may be on site. Each soil type, or mixture thereof, has different properties and can act in different ways.  A skilled lab technician will be able to recognize the potential properties of each, and be able to determine best spots for soil extraction. It can also be valuable to take a sample from the stockpile. This is usually done if the technician notices that the stockpile soil has different properties than the other site soil, or because several soil types are being blended together.

Once at the laboratory the process of determining the optimum moisture content and maximum dry density will occur. A lab technician will start by sifting and moisture conditioning of the soil. Once the soil is prepped the soil will go into a cylindrical mold to be compacted at various moisture contents and weighted.

The test is to see how much of the material can be compacted into the same volume at the various amounts of moisture. When a material is too dry it can not compress very tightly. As more water is added, it is able to compact in better and better, so it’s dry density (unit weight calculated removing the water weight) is increased. Once it hits the limit that the material will allow, the water starts displacing the material and the dry density will start dropping, creating a “curve”. The peak of this “curve” is considered the maximum dry density and the optimum moisture for that specific material. Again, it is of vital importance to have an experienced lab for this process.

Nuclear Gauge Testing

The last key step in soil compaction testing involves the use of a soils nuclear gauge. Back at the job site, a field technician uses a nuclear gauge that has two radioactive isotopes (roughly the same mass as the head of a pin), and emits extremely small amounts of radiation into the soil. Inside of the machine there are sensors that detect how much of the radiation makes it back to the machine. One of the sources is for detecting the hydrogen content, which is a direct correlation with the moisture content. The other source is for detecting the wet density.

Using both of these readings, the nuclear gauge calculates the in-place dry density. This number is compared to the maximum dry density that was determined by the lab testing and is expressed in the form of a percentage. Typical requirements are between 90% and 95% of the maximum dry density. If the material changes even slightly, it could drastically affect the results indicating failure. An experienced field technician will notice the change and pull another sample for a curve rather than have the contractor keep trying to work the material wasting time and money.

What is Superpave?

/in /by

What is Superpave?

What is Superpave?

The history of Superpave dates to the 1980’s. During that time, it had become apparent that some pavement wasn’t performing as well as others. While one section of highway would be in great shape, just down the road, another section would be degraded and need repair. Due to that, in 1987, congress decided that we needed to improve our highway system. Subsequently allotting $150 million into a 5-year program called the Strategic Highway Research Program (SHRP). The goal of this program was to:

  • Determine why some pavement functioned better than other pavement.
  • Develop guidelines and tests that would ensure all pavement used will hold up to the highest standard.
  • Collaborate within the industry to guarantee the new qualifications were being used.

In 1992, Superpave was introduced. SHRP had found that by implementing 3 mechanisms our asphalt would become more sustainable against extreme weather and heavy traffic conditions. Asphalt binder specifications, a volume mix design and analysis system, and a mix analysis testing became Superpave.

What is Superpave?

Superpave has become a success.

Implementing Superpave on our highways has increased the longevity of our roads. Commuters are not the only ones positively effected by Superpave. For instance, almost all highways in the United States use asphalt pavements. Moreover, the yearly expense for asphalt pavement is over 10 billion. Furthermore, let’s not forget about the environmental impact.  The more sustainable our roads, the more we save. Superpave has done that!

We are proud to be one of the first!

BSK is one of the first Material Testing Laboratories in California to invest in Superpave.

Which means; we have been doing Superpave longer than most. And, experience is everything! Our personnel is not only trained, we have extensive experience in Superpave hot-mix asphalt technology. Our employees are knowledgeable in AASHTO/ASTM test methods, and hold applicable Caltrans certifications.  Additionally, our Livermore materials testing laboratory is accredited by the AASHTO Materials Reference Laboratory (AMRL) Program. Along with the Caltrans for testing in accordance with “Superpave” test methods, and Section 39 of the Caltrans Standard Specifications.

We offer Independent Assurance Laboratory & Testing Support.

  • Material Selection: Aggregate QA testing for gradation, evaluation of aggregate blends and binders.
  • Design: Verification of trial blends, asphalt structure, binder content, mix design.
  • Construction: Field QA testing of construction materials including soil, in accordance with ASTM.

BSK: Gem Lake Dam Project

/in , /by

BSK: Gem Lake Dam Project.

BSK photo from helicopter.

BSK: Gem Lake Dam Project.

We are excited to announce that BSK conducted a Geotechnical Engineering Investigation for Gem Lake Dam!

Gem Lake is located on the eastern side of the Sierra Nevada mountain range near June Lakes. This rural area is a hiker’s paradise with beautiful trees and lush vegetation.

Gem Lake Dam was originally built in the 1920’s and is a key element of the Rush Creek Hydroelectric System. In fact, Hydroelectric Dam Systems produce 8-12% of the nations power, making these dam systems all the more important. Additionally, this particular hydroelectric system is considered an eligible renewable energy resource! Hence, all the more reason that BSK is so proud to be a part of this project.

Part of the Federal Energy Regulatory Commission (FERC) requirements is to have the ability to control water levels of these lakes. Thus, ensuring that in the case of a natural disaster, the public will be safe. Southern California Edison (SCE), who own the 3 dams that make up the Rush Creek hydroelectric system, is in the process of retrofitting these dams to guarantee the safety of the residents who live downstream of the dam.

How Are We Helping.

Gem Lake Dam is a reinforced concrete Arch Dam which consists of several arches. BSK’s responsibilities included the Geotechnical engineering investigation for the proposed valve replacement for Arch 8. This consists of; field exploration, laboratory testing, and engineering analysis. Basically, BSK will be assessing the condition of the soil below the new valve. Additionally, we will provide recommendations to the project designers for moving forward. Field exploration on this project began October of 2019. Site reconnaissance included geological survey, rock sampling, and ground resistivity testing. In addition, we conducted laboratory testing on the samples. These tests included; unconfined compression testing of rock; basically measuring how much force is needed to crush the rocks.

 

Gem Lake History and Findings.

BSK: Gem Lake Dam Project.

This will not be the first time the dam has seen work over its almost 100 years of existence. In fact, shortly after its conception, the dam began to show signs of deterioration. Upon investigation it was found that a high water/cement ratio was used, causing the efflorescence and deterioration. This finding, along with other concrete studies, is why the American Concrete Institute now recommends a water/cement ratio of no more than 0.45 for poured concrete. In turn, these types of regulations and findings led to the conception of what we do at BSK.

Why We Love It.

Earthquakes, floods, fires, and other natural disasters have taught us what needs to be done to keep the public safe. We have learned what our soil, buildings, water,  and roads need to withstand natural disasters. Due to this, we have enacted rules and regulations. BSK has Engineers and Geologists that are trained and educated to know how buildings need to be erected; what soil/foundation standards need to be in place. We have inspectors that are licensed to know if a buildings weld joints will react accordingly in an earthquake.  We have laboratories that can test if the water system has been exposed to an outside contaminant. In essence, our work at BSK deals with keeping the public safe. Above all, we take pride in knowing that what we do on a daily basis at BSK makes our communities safer and stronger!

Arroyo Del Valle Bridge

Arroyo Del Valle Bridge.

Thanks to the efforts of the Tri-Valley Conservancy the Tri-Valley Trails are being connected!

 

 

 

 

 

 

 

 

 

 

 

 

The Arroyo del Valle Regional Trail, in Sycamore Park, will no longer lead visitors and wildlife to a dead-end trail. With the addition of the Arroyo Del Valle Bridge, the area has become part of a continuous 44-mile regional trail into Del Valle Regional Park, Ohlone Regional Wilderness, Sunol Regional Wilderness, and Mission Peak Regional Preserve. Connecting the 5 parks will allow visitors seventeen times the trails to peruse. Furthermore, this connection will enable access for people with strollers, cyclists, and those with disabilities. As for the wildlife, they benefit from the bridge too! Connecting the bridge enabled an interconnected habitat. It’s an amazing win for the entire community!

 

BSK’s Contribution to the Arroyo Del Valle Bridge.

BSK’s Livermore Office is proud to be part of the Tri-Valley Conservancy’s team for the construction of the Arroyo Del Valle Bridge. BSK supported the Arroyo Del Valle Bridge project with observation of helical anchor installation, earthwork compaction testing, reinforced concrete inspections for the bridge abutments, and high-strength bolting inspections.  Sequentially, we know this bridge was inspected by the best in the business! Additionally, we’d like to give a big thanks to Danaige Tower, Michael Romero, David Eckhardt, KC Clark, Omar Khan, Veronica Rager, Don Steckbar and Dennis Ness for their support to the project. Check out the photos below to see the BSK crew in action!

lastly, bridge is done.

Lastly, we are complete!

 

 

On Friday, September 27th, the bridge assembly was completed, lifted into place, and anchored to the abutments.  Many thanks to the Tri-Valley Conservancy for the invitation to watch the bridge pick and including members of our project team at the event!

BSK: National Safety Preparedness

/in , , /by

BSK: National Safety Preparedness Month

September is National Safety Preparedness Month and at BSK Associates we take safety and preparedness very seriously.

Developing a Plan.

There are several ways we can prepare for emergencies and natural disasters. However, planning is the best way to start. Department of Homeland Security advises that you begin by finding out the types of disasters  that could occur in your area. Next they recommend that you discuss your plan with your family and friends. Decide how you will stay up to date on emergency alerts and warnings. Choose a shelter plan. Figure out which route you will take to evacuate, and how you will stay in contact with your loved ones.

The next step recommended, when forming a clear and concise emergency plan, is to figure out your specific needs as a family.  Additionally, you need to have a plan in mind so that you will be able to meet those needs. Do you or a family member require certain medication? Does anyone have a disability? Do you have pets or children in school? If you do have children, it is recommended that you download the Emergency Plan for Parents guide. This is a free guide provided by FEMA. Additionally on this website you will find several other free downloadable guides that will help to aid in your emergency plan.

Lastly, you should always practice your plan as often as possible. This is especially important if you have children. Being prepared and practicing for a disaster helps children feel safer if there truly ever is a disaster.
