Toolboxes and storage containers should be secured with heavy-duty padlocks and kept locked when not in use. The site will need security lighting and any construction trailer should be completely fenced in with portable chain- link fencing. The fence will provide both a physical and psychological barrier to any prospective thief. Construction trailers should be kept locked when not in use and should also have a heavy-duty deadbolt installed with no less then a 1-1/2” throw when bolted. Any construction material that contains copper should be removed from the construction site at the end of each working day or well-secured. Glass windows in the trailer should be shatter resistant. I also recommend Renton Regional Fire post appropriate “No Trespassing” signs on the property while it’s under construction. This will aid police in making arrests on the property after hours if suspects are observed vandalizing or stealing building materials. The use of off-duty police officers or private security guards to patrol the site during the hours of darkness is also recommended. COMPLETED BUILDING Access Control Access control is the ability to decide who gets in and out of your business. It’s important to direct all visitor foot and vehicle traffic towards the main entrance of the building. Designs submitted to the City of Renton do show that the main entry will be highlighted as the focal entry point to the building, directing path of travel towards a well-lit prominent entry point, through the use of lighting, landscaping, and special paving. Excess entry doors should be designed so that they automatically lock when closed and only serve as emergency exits. Windows should be designed so that they can’t be used as entry points for people, although some could be equipped to be utilized as emergency exits if needed. Doors/Glass All exterior doors should be made of solid metal or metal over wood, with heavy-duty deadbolt locks, latch guards or pry-resistant cylinders around the locks, and peepholes. All strike plates should have 2-1/2 to 3” wood screws. If glass doors are used, they Docusign Envelope ID: 9C8AD163-664C-4B8F-8817-4315F1866DB3 Page 2 of 3 should be fitted with the hardware described above and additionally be fitted with a layer of security film. Security film can increase the strength of the glass by up to 300%, greatly reducing the likelihood of breaking glass to gain entry. Security Since this fire station will be open and staffed 24/7, theft from the building should be minimal, unless someone is allowed entry to areas normally closed off to the public or they are left to wander unattended. Any alternative employee entrances should have coded access to prevent trespassing. Exterior doors should be checked routinely to insure they are not being propped open. There was no mention of cameras in the design plans submitted to the city. Cameras should be in place to monitor activity around the building, entry and exit points, for security and safety of staff. Lighting Lighting is collectively considered to be one of the most important security features. Good lighting has been documented to deter crime and produce a more secure environment. Good lighting also enhances the effectiveness of CCTV systems. All areas of parking and pedestrian travel need to have adequate lighting. This will provide safe pedestrian travel for employees and visitors. Proper selection and placement of lighting should adhere to the standards of the Illuminating Engineering Society (IES) as well as CPTED standards. Landscaping The “Broken Window Theory” says, “An ordered and clean environment – one which is maintained – sends the signal the area is monitored, and that criminal behavior will not be tolerated.” All trees should be trimmed six to eight feet up from the ground. Shrubs should be pruned to no more than three feet tall. This will help eliminate areas of concealment for suspicious persons. Trees and shrubs which are not maintained can cause safety issues. Since the planned landscaping will be in its “infant” stages once the fire station is completed, I do not anticipate this being an issue within the first few months. However, regular maintenance should be planned, and landscaping monitored to stay within the above-mentioned guidelines. Territoriality/Signage Territoriality refers to measures that reinforce a message of ownership over the business. The most straight-forward examples of territoriality are signs restricting access and directing visitors to the main entry doors and reception areas, as well as posting hours of operation. The public needs to be made aware at all times of what space is private and what space is public. Signs and graphics can also assure staff and the public that their safety is being monitored. Likewise, potential perpetrators may be deterred by a notice that they are under surveillance. Proper No Trespassing signs should be posted in conspicuous locations throughout the outside of the buildings so enforcement action can be taken if needed. Defining clear borders is another step that reinforces territoriality. A low fence or hedge around the edge of the property may not physically stop a trespasser, but it helps identify Docusign Envelope ID: 9C8AD163-664C-4B8F-8817-4315F1866DB3 Page 3 of 3 where public space ends and private space begins. Maintenance further reinforces territoriality. Any unkempt part of the property will soon send a message that no one is particularly concerned about or possessive of that part of the business. If the area remains neglected, it will also seem ideal for misbehavior or loitering. Docusign Envelope ID: 9C8AD163-664C-4B8F-8817-4315F1866DB3
