Key features of The Portland Loo® include:

• Open Design: The Loo has an open-air design, which promotes ventilation and visibility. The slanted louver design allows authorities, first responders and maintenance to monitor and ensure safe and clean facilities for users. The upper louvers are designed to optimize airflow, effectively reducing odors and eliminating the need for mechanical ventilation.

• Durability: The structure is made of high grade 304 or 316 stainless steel and designed to withstand vandalism, extreme weather conditions and corrosive marine air making it a long-lasting solution for high-traffic urban areas. The interior is equipped with heavy-duty, penal-grade fixtures and features vandal-resistant accessories for enhanced durability and security.

• Privacy with Visibility: While providing users with needed privacy, the design incorporates strategic low visibility features that allow for subtle monitoring by authorities, first responders and maintenance workers. This thoughtful approach helps deter illicit activities while maintaining a secure and safe environment for everyone.

• Accessibility: The Portland Loo® is ADA-compliant, offering seamless accessibility for individuals with all types of disabilities, including those who use wheelchairs, have visual impairments, or require additional support, making it an inclusive and welcoming space for everyone.

• Easy-Cleaning Features: The restroom is designed with features that help maintain cleanliness, such as a grated floor to allow water to drain away and discourage people from sleeping inside. The enhanced anti-graffiti powder coating adds durability to the stainless-steel structure while maintaining an easy clean surface.

The Portland Loo® was designed not only for functionality but also to fit into the city’s urban landscape while addressing social and public health needs. It has been widely recognized and replicated in other cities across the United States as a model for public restrooms.

The Portland Loo® was designed by the City of Portland, in a collaboration with the architectural firm Miller Hull. The design was developed as a response to the city’s need for safe, durable, and accessible public restrooms, especially in high-traffic areas. The team worked closely with city officials and other stakeholders to address the challenges of hygiene, safety, and maintenance in public restrooms, resulting in the creation of the highly functional and innovative Portland Loo.

The City of Portland first installed The Portland Loo® in 2008, responding to the growing need for more accessible, safe, and durable public restrooms. The inaugural Loo was placed in the Old Town Chinatown district as part of a pilot project aimed at addressing restroom needs in high-traffic urban areas.

Still in use today, The Portland Loo® in Old Town Chinatown has become a vital component of the city’s public restroom infrastructure. It has effectively met the community’s needs by offering a secure, clean, and accessible restroom in a bustling area, while also serving as a model for similar installations in other cities across the country.

The city utilized the principles of CPTED to determine the placement of the Old Town Chinatown restroom and continues to apply this approach in its ongoing urban planning and public safety efforts.

CPTED stands for Crime Prevention Through Environmental Design. It is a multidisciplinary approach to crime prevention that focuses on the design and layout of physical environments to reduce opportunities for crime and improve public safety. The core idea is that urban and architectural design can influence human behavior in a way that discourages criminal activity and promotes a sense of security.

Key principles of CPTED include:

1. Natural Surveillance: Designing spaces to increase visibility and allow for monitoring, making it easier for people to observe what’s happening around them.

2. Territorial Reinforcement: Encouraging a sense of ownership and responsibility over spaces, so people are more likely to care for them and report suspicious activities.

3. Access Control: Designing environments in a way that limits or controls access to certain areas, making it more difficult for potential offenders to enter or hide.

4. Maintenance: Ensuring that spaces are well-maintained, which can foster a sense of care and reduce the likelihood of neglect that may encourage criminal activity.

CPTED is often used in urban planning, public safety, and architectural design to create safer and more inviting public spaces.
