Physical environment greatly influences crime, fear of crime, and quality of life. The relationship between physical environment and crime has become more evident in recent decades as people make increasing use of loc ks, bars on windows, cameras, and alarm systems. Although these tools can have a legitimate role to play in crime prevention, they are not the complete answer. For a crime prevention strategy to be effective, it must be comprehensive. The solution is an approach called “ CPTED,” or “Crime Prevention Through Environmental Design.” As defined by the National C rime Prevention Institute, CPTED is: …a crime prevention philosophy based on the theory that the proper design and effective use of the built environment can lead to a reduction in the fear of crime as well as an improvement in the quality of life. CPTED works by decreasing a criminal’s ability to commit crime and increasing the chances that the crime will be seen by legitima te citizens. CPTED goes beyond traditional security methods by naturally integrati ng security measures into the community. The goal of ALL CPTED applications is to : Increase the Quality of Life Decrease Fear of Crime Decrease Crime By following the strategies presented in this handbook, homeowners, apartment residents, and business owners can achieve each of these goals. On pages 2-5, you will find additional information about how CPTED wo rks. On pages 6-10, there are special CPTED surveys meant specifically for single family home residents, apartment residents, and business managers or owner s. The pages on lighting describe the various lighting types available and t heir efficiency. CPTED Security Handbook 2 Why does it work?

CPTED is effective because of a concept called “defensible space.” This concept suggests all space in the human environment is defe ndable: someone may take responsibility for the space and take action to def end it from non-legitimate, criminal, or unintended use. Alternately, space can be undefended. When there is no identifiable person who is responsible for the spac e, it is left exposed to criminal use.

Crime is more likely to happen at a location if it is not defended, and crime is less likely to occur if an area is defended. The person defending an area may be the owner of the property, but they may also be a tenan t, a property manager, or an employee. In order to defend a location, it must be clearly identified and delineated, it must be modified to prevent access of unauthorized perso ns, and it must provide good visibility for witnesses in the event of a crime. T he purpose of CPTED is to allow these things to be accomplished in ways that do not interfere with non-criminal activities. Does this sound difficult? Surprisingly , it is not. Defending a location may be as simple as building a small fence, installing an address marker, or cutting back weeds. CPTED works because criminals avoid doing crime in the presence of legitimate citizens. Property that has been properly defended suggests to a criminal that a legitimate citizen may be near to witness the crime and call the police. Property that is not defended tells the criminal that no one is w atching and they are safe to commit their crime. Like the t able at the right shows, undefended places that are safe fo r criminals to commit their crimes are unsafe places for legitimate citizens... Alternately, places that are defended and safe for legitimate citizens cause the criminal to fear detection and arrest for their cri mes. The CPTED goal is to make every location unsafe for cri minal activity while also making the same locations safe and inviting for legitimate citizens. Unsafe Safe Citizen Criminal Criminal Citizen CPTED Security Handbook 3 How does it work?

CPTED is applied in the community through one of four overlapping strategies.

Each strategy employs a slightly different method o f sending a clear message to criminals that a responsible person is nearby and t heir activity is not welcome. This section of this handbook will tell you about each o f the strategies, and you will learn how to begin applying them in the next section. Natural Surveillance Natural Surveillance is the placement of physical f eatures, activities, and people in ways that maximize the ab ility to see what is occurring in a given space. This is often t hought of as the only strategy of CPTED, but it is only a quarter of successful CPTED effort. An example of natural surveillance is a parking garage built with large panoramic windows facing a major street.

This allows pedestrians and motorists to see into t he parking area and detect criminal activity. This strategy works b ecause criminals will not commit crimes in areas where they feel exp osed to observers. In the event a crime does occur, there i s a greater chance that it will be witnessed and reported to police. Territorial Reinforcement Territorial Reinforcement is the use of buildings, fences, signs, pavement, or other objects to express ownership or to clearly delineate the transition from public space to priva te space. For example, a small decorative iron fence can be place d around a front yard. The fence separates the public roadway and sidewalk from the front yard and makes a clear statement tha t non- legitimate users are not welcome in the yard. This strategy works because it suggests there is someone present who ha s responsibility for the space and may observe crimin al activity. Access Control Access Control is the physical guidance of people coming and going from a space by the placement of entrances, exits, fencing , landscaping, locks, and other barriers. For example, walkway bollards may b e placed near the entrance of a park to prevent vehicle entry but all ow pedestrian entry. This strategy works because it creates a barrier against improper vehicle movement into the park. In the event vehicles do en ter the park, the presence of the bollards makes the inappropriate be havior clear to citizens passing by and they can notify police. A component of Access Control is called Target Har dening. This refers to:

Deadbolt locks Window locks Sliding glass door locks Alarms CPTED Security Handbook 4 Maintenance The upkeep of an area demonstrates that someone cares and is watching. For example, a business may be regularly painted to mai ntain a clean appearance. This strategy works because of what is known as the “Bro ken Windows Theory.” This theory suggests that a neglected space will elicit mistreatment by people, while a maintained space will elicit proper treatment. This strategy directly impacts the fear of crime in a community due to resident’s perceptions of responsibility and caring in neighborhoods. CPTED Security Handbook 5 How do I do it?

Any person wanting to protect their property with the use of CPTED must first ask themselves a question: What am I trying to accomplish in this space?

Only after the true purpose of a space is recognize d can CPTED be properly applied.

The reason for this is that many times, a space is constructed to serve one purpose but is used for another. If CPTED strategies are us ed to affect the intended purpose, the strategies may have little or no effect on the true use of the property. For example, a resident may have problems with peo ple standing or sitting in his front yard while waiting at a nearby bus stop. The resident attempts to keep these people off his property by building a brick wall, b ut the wall only serves to create a bench for the people to sit on w hile they wait for the next bus! The resident must ask himself wha t he truly wants to do with the property. If he chooses to hav e a private front yard without the distraction of bus passengers, then the resident needs to consider rem oving the wall and replacing it with a short picket fence or short bushes; things that may not easily be used to sit u pon. CPTED Security Handbook 6 Using the surveys In order to help you best answer the question “What am I trying to accomplish in this space?” and properly apply the CPTED strategies to your pro perty, the CPTED surveys in this book are separated into residential surveys and business surveys. To use them, select the one that is most appropriate f or you and go to work! Each survey asks you questions about the property, and t hen directs you to another portion of this booklet for the applicable strategy . While you are completing these surveys, please rem ember that the CPTED suggestions are made for the purpose of reducing th e likelihood of criminal activity on your property. While no guarantee can be stated or implied, the concepts of CPTED have proven themselves internationally. The O akland Police Department offers this survey as a public service, with the un derstanding that there is no way to predict or prevent all crime ris ks. The purpose of this survey is to reduce the formability of crime by making a good faith effort to provide a safe enviro nment.

Direct questions about this survey or your survey r esults to the Oakland Police Department, Neighborhood Service s Division at 510 238- 6200 or 510 238-2096. CPTED Security Handbook 7 Residential Survey Residents are the core of any community. Their well-being directly impacts the health of the community and its ability to prosper. Residents who feel safe from crime in their homes and neighborhoods will be more willing to get involved in activities that strengthen and protect the communit y. Alternately, residents who don’t feel safe often turn their homes into fortres ses to protect themselves and they avoid contact with the community. This can contribu te to the decline of the neighborhood and create a rise in crime! All Oakland residents are urged to spend approxima tely an hour of their time to complete this residential CPTED survey. The survey will allow residents to locate problems on their property, identify possible strat egies for fixing the problem, and ultimately affect crime and quality of life in Oakl and. Notes: CPTED Security Handbook 8 Using the Residential Survey In the survey below, you will find each of the four CPTED strategies listed with their proper application. Survey your property and compar e it to each of these design elements, then rate the results in the space provid ed. A “NO answer suggests that your property may not be “CPTED-safe”. In this case , consider modifying your property to satisfy the design element, or seek mor e direction from the CPTED Strategy Reference portion of this handbook. Present? Natural Surveillance YES NO All doorways that open to the outside should be wel l lit. The front door should be at least partially visible from the street. Windows on all sides of the house provide full visi bility of the property Sidewalks and all areas of the yard should be well lit. The driveway, or where you usually park your car, s hould be visible from either the front or back door and at least one window. Landscaping should not create blind spots or hiding spots. Front facing balcony railings, fences, or walls should never be constructed of solid material or be higher than 36”. Window treatments on 2 nd story, front-facing windows should be kept open an d provide a view to the front of the property. Present? Territorial Reinforcement YES NO Property lines and private areas should be defined with plantings, pavement treatments, short walls, or fences. The street address should be clearly visible from t he street with numbers a minimum of 5” high that are made of non-reflective material. The numbe rs should also be clearly lighted at night. The property should encourage interaction between n eighbors with low property-division fences, bushes, or landscaping transitions. The mailbox should be clearly marked with the stree t address. It should also be as close as possible to the front of the house and visible from the house. Present? Access Control YES NO Walkways and landscaping should direct visitors to the proper entrance and away from private areas. Door locks should be located a minimum of 40 inches from adjacent windows. Exterior doors or interior garage doors should be hinged on the inside and should have a single cylinder dead bolt lock with a minimum one-inch thr ow. All windows should have locks. Sliding glass doors should have a locking device or locking pin on the movable portion of the door. Detached storage sheds or other buildings should be equipped with lockable windows and doors. Present? Maintenance YES NO Keep structure painted and in a condition of good r epair. Keep weeds abated. Trim bushes to 36” high and tree s up 7’ from the ground. Don’t store old automobiles, boats, trailers, or other vehicles in your front yard. Keep landscaping tidy and in good repair. CPTED Security Handbook 9 Commercial Survey For a neighborhood to remain healthy, its local businesses must flourish; and for businesses to do well, they must be safe places to frequent. Perceptions about the safety of business areas directly impacts the healt h of the community and its ability to prosper. Patrons who feel safe from crime in bus iness areas will be more willing to return. Business owners are urged to spend approximately a n hour of their time to complete this business CPTED survey. The survey wil l allow owners to locate problems on their property, identify possible strat egies for fixing the problem, and ultimately effect crime and quality of life in Oakl and. Notes: CPTED Security Handbook 10 Using the Commercial Survey In the survey below, you will find each of the four CPTED strategies listed with their proper application. Survey your property and compar e it to each of these design elements, then rate the results in the space provid ed. A “NO answer suggests that your property may not be “CPTED-safe”. In this case , consider modifying your property to satisfy the design element, or seek mor e direction from the CPTED Strategy Reference portion of this handbook. Present? Natural Surveillance YES NO Windows should face rear parking lots for increased visibility. Window signs should cover no more than 10% of windo w space. Interior shelving and displays should be no higher than five feet for increased visibility. Exterior and parking lots should be well lit. Loading areas should not create hiding places. Clear visibility should be maintained from inside the business to the street, sidewalk and parking areas. All entrances should be under visual surveillance b y employees. Non-working or unattended surveillance cameras shou ld not be used. Exterior parking lot lighting should be free-standing and not mounted to a building. Present? Territorial Reinforcement YES NO Property lines and private areas should be defined with plantings, pavement treatments, short walls, or fences. Businesses should be identified by wall signs for t hose parking in the rear. Reception and cash register area should be position ed to screen all people entering. Parking areas should be clearly marked and separate d from pedestrian walkways. Present? Access Control YES NO Walkways and landscaping should direct visitors to the proper entrance and away from private areas. Cash register should be located in front of store. No easy access to the roof. Exterior doors should be hinged on the inside and sh ould have a single cylinder dead bolt lock with a minimum one-inch throw. All windows should have locks. Detached storage sheds or other buildings should be equipped with lockable windows and doors. Present? Maintenance YES NO Keep structure painted and in good repair. Keep weeds abated. Trim bushes to 36” high and tree s up 7’ from the ground. Keep all lighting fixtures in good operating condition. CPTED Security Handbook 11 CPTED Strategy Reference Natural Surveillance Place lighting in such a way that it allows people to be recognized from 25’ away. Avoid directing the lighting so that it glares into your eyes or into the eyes of persons passing by on the sidewalk or street.

Glare may prevent you or passersby from seeing and identifying visitors to your door. Try to keep the light a whit e color to allow visitors to be better seen. Prune shrubs to no more than 36” high and trees up 7’ from the ground. This allows you to maintain the shade provided by trees and the curb appeal of shrubbery, but it also provides a clear, unobstruct ed view. It also prevents criminals from easily hiding on your property. Leaving the window coverings open on at least a few front-facing windows creates the perception with people passing by that you are watching and will witness any crime that occurs there. Consider removing fences or walls that obstruct you r view of the street. If you can’t see out, then these areas may also provide a criminal a good place to hide near your house, lay in wait for you, or conceal th eir efforts to break into your home or business. In a business, maximize natural surveillance by kee ping windows clear of posters, signs and other obstacles. Promote “eyes o n the street” concept.

By elevating the front counter/cash register area i n a store, the clerks will have greater natural surveillance capability throughout the store.

Territorial Reinforcement Plant grass, flowers, or other shrubbery, or instal l short walls, fences, or other delineators to clearly show the line between your p roperty and public property such as the roadway, sidewalk, or other easement. T his demonstrates that you are responsible for your property, unwanted visitor s are not welcome there, and you may call the police if a trespass occurs. A clearly defined street address allows police and fire services to find you easily in an emergency. It also sends a message to people on the street that you are taking responsibility for the property and have mar ked it as your own. Particularly in the front yard area, maintaining yo ur landscaping to provide good access and visibility with your neighbors crea tes the image of a close-knit community. It suggests neighbors will protect each other if threatened by a criminal. This can be done by removing tall fences or bushes and replacing them with a low property line fence in the front yard, a strip of landscape edging, a planting of flowers, or even a path that connects t he properties. Address numbers on your mailbox not only assist the mail carrier, they show that you are responsible for the box and the mail c ontained inside. Your mailbox should also be as close to your home as possible in order to reinforce it as being your property and your responsibility. However, do not move your mailbox from its current position without first consulting with the local postmaster. CPTED Security Handbook 12 In offices, locate the reception area so that peopl e have to pass through that area to gain access to other areas of the building.

Proper signage on business property helps send a cl ear message. Examples such as Private Property—No Trespassing, Hours of Usage, Residents Only, and No Vehicle Traffic tell a person that someone is manag ing the property.

Access Control Make certain the path to your front door is clearly identifiable. It must leave no question about the proper way to approach your home . This allows potential criminals who don’t approach properly to be more ea sily noticed. Make sure all exterior doors are solid-core and are secured by at least one deadbolt with a minimum 1” throw. This helps to kee p the door from being pried or kicked open. This is especially important with interior garage doors or other doors where the criminal is hidden from view. Keeping the door locks at least 40” from windows pr events criminals from breaking the window, reaching through the hole, and unlocking the door to get inside you home. All windows and sliding doors in your home should h ave locks to keep them from being pushed open from the outside. In stores, entrances for the public should be limit ed and visible to employees.

They should also be well marked and have appropriat e lighting.

Directional signage, roadway or parking lot marking s and use of other devices give guidance to people using the location. These d evices allow employees at the property to observe those people who are not obeyin g the rules, which might prevent criminal activity.

Maintenance Keeping your home or business painted, clean, and r epaired sends the message that you are taking responsibility for your propert y and will call the police in the event of suspicious or criminal activity. The storage of vehicles in your front yard for long periods of time creates several problems. It presents a target for potential car th ieves or vehicle burglars. It creates places for trespassers or criminals to hide . It may also create the image that the vehicles are abandoned and uncared-for, an d no responsible person is present to call police. Keeping outdoor lighting in good working condition allows for better natural surveillance and helps prevent criminal activity on your property.

CPTED Security Handbook 13 Lighting Lighting by itself does not prevent crime. Lighting provides the opportunity for “choice”; the choice to walk forward because you ca n see clearly that the path is clear and free of danger. If the user can see a potential danger (a person hiding, a group of misbehaving kids at the corner), they may choose to walk a different way.

However, lighting can illuminate a target for a cr iminal as easily as it allows a legitimate user to see a potential threat or crimin al. For this reason, lighting must be applied properly. Unless you have natural surveilla nce of an area, lighting may not always prevent crime. In fact, good lighting withou t surveillance may actually encourage criminal activity. Lighting is a powerful tool that management and re sidents can use to control and reduce the “fear” and opportunity of crime.

Goals of lighting Security lighting should be Energy efficient (used consistently) Non-tamperable (use special screws) Break-resistant lens (Polycarbonate-Lexan) Building lighting should Illuminate building numbers Illuminate building accesses Illuminate front and back areas Illuminate porch lights under control of building, not apartment user.

Illuminate the corners as well as walls. Grounds lighting should Provide a cone of light downward to walkways, prefe rably from the side. Provide a level of lighting between buildings to di stinguish forms and movement.

Common types of outdoor lighting fixtures Energy-efficient lighting fixtures help you cut you r electric bill. Additionally, most products are easy to install because many models co me pre-wired and pre- assembled. Each style comes with a lamp and you can also choose to add a photocell on some designs.
