It's much simpler to think about just that initial process of "bugging out" when things go bad, than staying put. However, the harsh reality is that bugging out is the last thing you should ever want to do. The entire concept of bugging out requires that you be willing to sacrifice the known for the unknown. In order to be willing to take this step you should have no other option available to you.
So while it is obviously a very sound idea to have a planned bug-out destination (or even several), along with a "get-home" bag in the car and/or office, the purpose of this article is to walk through a more important step of prepping your own home and neighborhood (i.e. "home base") for a post-disaster situation.
In an urban environment, or any environment that involves our home, we can break these 5 necessities down in several different ways, and in doing so the essential concepts expand just a little bit into sub-areas. I like to break it down as follows: Water, Food, Heat/Cold, Power, Communication, Light, Health and Security.
As an example of this break-down of needs, rather than just the basic necessity of "fire" we ideally need to be able to both heat and cool things like food or possibly even our living environment.
Firstly because it doesn't take that much room or money to plan for that amount and also because you'll be glad you overestimated a little.
As an additional backup water plan, you should also invest in at least one water filtration system (for example: Berkey water filters), and also invest in one or more of the numerous and inexpensive, portable bugout-bag type systems.
However the first and most important necessity to start with is having a supply of water that does not need filtration or purifying. It is very simple to buy several 55-gallon, food-grade plastic barrels. The prices for these range from about $25 - $50, depending on whether they are new or used, and also depending on whether they already have a spout installed at the bottom or not.
Alternatively, the 5-7 gallon plastic water containers you can buy for under $10 will work as well. They are usually square and stack neatly.
b. Water for sanitation - Most people don't consider this aspect, so let's think about it here: Disasters like hurricanes, tornadoes, floods, earthquakes create an huge mess of sewage, salt-water (near the coast), agricultural waste, and much more.
This means that even a minor cut, abrasion or laceration can become life or limb threatening, especially if medical care is limited. Proper sanitation means that we need water for washing off (shower), cleaning our teeth, cleaning out wounds and other first aid needs. Also we need water for helping clean and take care of toilet needs, whether that amounts to 5-gallon buckets, trash bags, or even a trench in your back yard.
c. Water for food - If you're growing your own food (and you should be), then of course you will need water for that. In most urban areas it is rare to find very much water supply that is gravity-fed. This means that a power outage results in no water supply for your home, garden, greenhouse, etc.
How much water does it take to keep your food growing? Do you know? One way to track this is to set up a gravity drip system with PVC pipe drip irrigation (drill holes in it) and a 35 or 55 gallon drum. It doesn't cost much to create this and saves a lot of water even when your water supply isn't restricted. Rainwater collection or other sources of gray water are also a very good plan.
Rainwater collection, depending on where you live, is a good plan for drinking water too, but requires specific filtration in that case as well. Bear in mind that there are some states where rainwater collection is actually illegal. The constitutionality of this kind of regulatory practice is outside the scope of this article, but it is something to be aware of before you start building your own system.
While it's true that these have calories to keep you alive for a short-term disaster (less than a few weeks) they are not any kind of real food for the medium or long haul. The only real advantage you get from those short-term foods is portability and weight. So I'd recommend having Mountain House or MRE's in a small supply that you can either pack into your car or bugout bag very quickly (if not already pre-packed), in case you have to become mobile. Otherwise use real food for your home-base prepping and stay away from prepackaged food entirely for that purpose.
You can very easily and inexpensively take care of all of your food supplies. Start with extremely inexpensive with foods like beans (red beans, lentils, etc.) and rice. Then build up from that starting point by using food drying (dehydrators like the Excaliber brand, for instance, can be bought starting at around $100) dry canning, wet canning, mylar and food-grade storage buckets to package and store your food. The important thing is to store your long-term food in vacuum sealed containers that will allow your food supplies to keep for several years. Storing your food in this manner is a skill, but one that is very easily learned. We teach these skills at my school, but you can also learn many of them on your own through "YouTube University" or through good books.
3.) Power: Power is very useful for at least four very important things, which are all part of the sub-necessities I mentioned earlier in this article. Heat, cooling, light and communication. While you are thinking of the power-related ways to take care of these necessities, bear in mind that for most of them, there are non-power methods of taking care of these necessities as well. They might not work as well, but they are good backups.
a. Heating and Cooling: Start here with backup methodologies for heating and cooling your food that do not require power. This way you always have something to fall back on if everything else fails. For instance, examples of non-power sources of heating would be outdoor BBQ grills, fireplaces, fire pits & burn barrels. Examples of non-power sources of cooling food are root cellars, clay pot evaporative cooling, natural water or cooling (streams, creeks, springs, snow, etc.) and easy/cheap variations of underground food storage such as buried 55-gallon drums.
Then work on setting up at least one power-related backup source, such as generator, wind, solar, hydroelectric, etc. This subject alone is the material for many books. A generator is of course the simplest way to start, but don't assume that will take care of your needs indefinitely. There are many considerations even with something as simple as a generator such as fuel (gasoline, diesel, tri-fuel, propane, etc.), decibel level, fuel storage and so forth. Don't let the size of any task outlined in this entire article seem daunting to you. Remember, big tasks are nothing more than a lot of small tasks all piled into one stack. Just work on one small piece at a time and make sure you have your most basic and simple elements taken care of first.
b. Light: The easiest way to begin with light is again the non-power backup solution. Make sure you have candles available, as well as more than one way to light them. Power-based lighting is not only necessary to function in the home at night, but also for security outside and inside the home. Along with this (and part of security as well) is the concept of night-vision devices. However, remember that here we are talking about power in the form of batteries, so you need recharging systems (preferably sustainable like solar), and should try to keep all of your batteries the same size as much as possible (e.g. all "double A" or all "triple A") which makes it a lot simpler to store backups and create recharging systems.
c. Communication: In addition to the aforementioned power sources, consider charging your peripherals like cell-phones, laptops, radios, etc., with DC power sources that can be achieved using very common, inexpensive accessories, such as small solar chargers and small (300-1000W) inverters that will run off of a car engine (cigarette lighter or battery). As with every sub-topic in this article, communication is deserving of at least one long article of its own. There are a variety of methods of two-way radio communication -- MURS, FRS, CB, MB, ISM, HAM, etc., and much to know about each of them. In general, look first to 12V systems like CB for short range and HAM for long range. Both of these types of radio communication are also trafficked by users who at least have thought (if not planned) for post-disaster types of situations, whether on a highway, in a city or across an entire nation.
The amount of health care that can be taken care of using medicinal plants is phenomenal. It equals any mainstream, allopathic approach for all but the most dire of infections (and these days even that point is arguable because of antibiotic resistance) and of course medical or trauma situations that require surgery. For this reason, I feel that any real, long-term medical prepping should involve the study and skill of herbal medicine, to of course include growing your own medicinal garden as well as identifying medicinal plants in your neighborhood and yard.
However, much more important than the first aid kit itself is knowing how to use the first aid kit! This also means knowing exactly where the items in your first aid kit are, while under stress and in low-light conditions. It's one thing to search for some Band-Aids at a leisurely pace but quite another to be frantically searching for ACE wrap, headlamp and gauze while someone you care for is screaming and bleeding in the middle of the night in front of you.
I prefer first aid kits and packs that lay out flat so that they can be hung up next to you on something, or just laid out on the ground/floor and don't have to be dug through vertically. Also, whatever your kit contains, use it.
You need to rotate supplies through your kit constantly just like your stored food, so that it doesn't just sit and decay over time. Use your first aid kit every chance you get. Even for the most minor injuries. Practice finding things you need in your kit in darkness. Using your kit all the time will also help you in tweaking your supply choices as you realize what is useful and what isn't.
Finally, I would advise against buying pre-made first aid kits unless you have no other choice in the matter. Build your own. It's cheaper and in the end is much more effective.
If it does turn into a gun battle however, it is important to remember that if someone actually makes it inside your home you have already lost a good part of the battle. Real home security actually starts with a radius of several hundred meters around your home, at least.
On the down side, securing a neighborhood requires a lot of community involvement both before as well as during and after a disaster happens. Depending on your neighborhood, this can be easier said than done. If you live in a neighborhood with people who really don't care about preparedness (and most of us do), it is difficult to get people willing to think about concepts like this. However, training and learning these concepts yourself means that you will be much better equipped to lead (again, leadership being something we teach at our school constantly) and even to deal with people who don't have any idea what they are doing, other than getting in the way.
On the subject of securing your own home, again consider the security at least where your property starts, if not further out. Motion detectors are very useful, especially for areas that you cannot observe.
Additionally, find the best concealed routes to and from those vantage points. It is useful to stock up on plywood and nails or screws to be stored in an area you can get to without going outside.
This allows you the ability to block off windows (and doors) from easy entrance while providing concealment and some minimal cover from weapons fire. Cinder blocks are the next easy step up from plywood. Reinforcing doors means both the hinge side as well as the latch side of the door. The stronger the door frame and the portions of the door that attach to the frame, the more difficult it is to use force to enter a home.
If a person tries to bash in the door with a kick or an object, and only makes a hole or dent in the center of the door, they've basically just provided you with a bulls-eye to shoot at.
Another very important concept to think about is egress (and ingress) into and out of your home and into and out of your neighborhood -- in case the point is reached where you really have no better option than to bug out, or in case you are providing shelter to other neighbors who need to get into your home and help out.
In other words, the level of security you invest in should be proportional to the amount of community around you (as well as location, area defensibility, likelihood of disaster and attack, etc.) that that you think you would be facing. If it is only you and your small family, then make egress and ingress a priority.
No, you don't want to bug out, but you also don't want to stick around for an attack by 10 raiders who know what they are doing. Frankly, if even the same size force as you have inside your home really wants to raid your home they're probably going to be able to do it, given a few days' or more time.
There are so many aspects to defending against a force that would siege your home, from the psychological stress of being waited out and not being able to leave the home, to being burned out or gassed out with poisonous gas like insecticide, etc., that your best defense again is by far neighborhood security.
So as a final point in the security of your home, you also have to ask yourself why someone would want to raid you in a post-disaster situation in the first place.
Sometimes laying completely low and pretending to be an abandoned home might be your best option. Other times a show of force is the best choice. In a neighborhood that is secured, the show of force is generally what happens. If it's just you and your family inside a home in an unsecured neighborhood, you will have to make critical decisions as to the best strategy.
If everything in your security plan falls apart, then having good intelligence and awareness will at least allow you to make an informed decision as to whether to stay or bugout, not to mention routes to take and many other aspects of bugout preparedness you need to make in the time you have to plan your egress and trip.
Bugging out means you want to have a concealed route and means out of your home base; at the same time, a bugout bag or gear and a route and destination in mind.
As a final thought, I will leave you with the "4 A's of Survival" as I like to teach them in my urban and primitive survival classes:
Attitude: You cannot survive anything if your attitude is not where it needs to be. This means everything from how you deal with discomfort to whether you really want to survive or not. Your mind is your greatest tool and greatest weapon. Attitude is the lubricant that allows it to work correctly.
Adaptability: You must learn to become adaptable because there is no way to predict everything that can happen.
Awareness: Being aware of what is going on around you gives you an immense advantage in every aspect of survival. It also requires much less energy to avoid a bad situation than to try and get out of one.
Accountability: Accountability is essential on every level of both teamwork and leadership. Being prepared for a disaster is not a lone-wolf activity -- at least not for long. If you want to function well as a team or community you must be accountable for both good and bad decisions and be honest and sincere in your dealings with everyone you are working with.
