DeafScape: Applying DeafSpace to Landscape

DEAFSCAPE APPLYING DE AFSPACE TO L ANDSCAPE ALEXA VAUGHN

DeafSpace sprang from the heart of the Deaf community at Gallaudet University1 in Washington, D.C., in 2005. With the guidance of architect Hansel Bauman—who is hearing, but uses American Sign Language (ASL)—the Deaf community at Gallaudet came together through courses and workshops to create radical, bilingual, and highly collaborative discourse on designing more effective campus buildings and public spaces for people who are Deaf and Hard of Hearing (HoH).2 The resulting product is Gallaudet University's DeafSpace Design Guidelines (DSDG), an ever-evolving publication designed for use by architects, planners, and administration.

Defined by the DSDG, DeafSpace is a space “in which Deaf culture, in all its diverse dimensions, can thrive through full access to communication and the unique cognitive, cultural and creative dimensions of the Deaf experience are encouraged.”3 Within a predominantly hearing world, the built environment poses many real, physical barriers to people who are Deaf, as well as people with disabilities. These barriers range widely from the absence of visual signage on public transportation to the lack of space to communicate with sign language while walking on public sidewalks.

Deaf people have spent their lives adapting to the built

environment. Those who deviate from the 'norm' are expected to make adjustments to fit themselves seamlessly into society— regardless of ability—particularly in public space. As a result, the built environment is viewed as static rather than flexible. While people with disabilities have been guaranteed rights to public space through the Americans with Disabilities Act (ADA) since 1990, these regulations are not exhaustive, and historically have given less attention to those who are Deaf and HoH.4 With recent challenges to the ADA as we know it under H.R. 620,5 designers must use their power to design beautiful and accessible public spaces for all.

Many of these guidelines appear to be standard practice in streetscape design, as per the ADA. However, they are often overlooked or treated as an afterthought.

Applying these simple guidelines to streets has the potential to go beyond the ADA in creating space for the Deaf community, increasing safety, improving circulation, and making better urban landscapes for all.

Ramps are preferred by many in the Deaf community; they can prevent barriers to conversation and minimize tripping hazards posed by stairs. They should be kept wide as pathways to accommodate for visual conversation.

VISUAL AND TACTILE CUES Shared sensory reach is deeply rooted practice in Deaf culture. Visual cues can aid people who are Deaf to safely use and travel through public space.

interiors and windows, but creating flow between interior and exterior—extending the line of sight outdoors—allows for greater use, understanding, and connection to the surrounding landscape.

Reflection can be applied to many landscape and urban materials (e.g., stone, metal, wood) to create subtle clues about surrounding activity. Materials should not be overly reflective to avoid undesirable glare. Natural lighting and night lighting should be maximized to prevent eye strain, but shaded exterior paths are also crucial for glare-free

comfort on sidewalks, which can be achieved with tree canopies and overhangs.

community. Easing and eliminating curbs in public more access to people who use wheelchairs or baby strollers. Rhythm can be employed in the landscape to provide continuous, recognizable visual references and alignment for signers. Tree placement (and canopy) is especially important in creating a visible pattern in the urban landscape along sidewalks. According to Sean Maiwald, a Deaf graduate student in public policy at The George Washington University, "immediate visual indicators of space" are crucial and should allow for wayfinding and understanding of use, "especially at a quick glance." Color (e.g., planting, façades, signage) can provide contrast for signing as well as visual orientation for wayfinding in busy urban hubs.

ENDNOTES 1 Gallaudet University is the only university in the world designed for Deaf and Hard of Hearing students and provides bilingual education in English and American Sign Language. Three of my colleagues quoted here (Behm, Maiwald, and Koplitz) are alumni of Gallaudet and contributed to DeafSpace in various forms and stages over the years, from conception to application.

2 Deafness is a spectrum: Deaf with a capital 'D' describes individuals that identify with a central deaf, cultural identity and who primarily use sign language. Hard of Hearing (HoH) describes individuals with some degree of hearing. Hearing impaired is an unacceptable medical term to the Deaf community; it carries a negative connotation, views Deafness as an impediment to well-being, and invalidates Deaf language and culture.

Furthermore, DeafBlind describes individuals who are both deaf and blind, with a unique cultural identity of their own.

4 The ADA has focused on visual emergency systems (e.g., strobe alarms) in places like hotels and real-time captioning in stadiums for the Deaf and HoH. 5 H.R. 620 (The ADA Education and Reform Act of 2017), if passed, will provide amnesty for access violators, allowing businesses to ignore ADA requirements until notified by a person with a disability, indefinitely. The burden is thus shifted to the person experiencing access discrimination, causing loss of civil rights to public space granted by the ADA of 1990.
