TEXAS ACCESSIBILITY STANDARDSTechnical Requirements for Barrier Free Design

Chapter 469 of the Texas Government Code tells us what the Texas

Legislature is trying to achieve. It clearly states the intent in the

opening section.

This chapter is intended to further the policy of this state ...to eliminate, to

the extent possible, unnecessary barriers encountered by persons with

disabilities, whose ability to engage in gainful occupations or to achieve

maximum personal independence is needlessly restricted.

& CURB RAMPS

CURB RAMP SURFACE

TECHNICAL MEMORANDUM 99-15

TAS 4.7.4(2) requires curb ramps to have a light reflective value and surface texture that significantly contrasts with that of adjoining pedestrian routes.

The only surface textures TDLR is currently aware of that meet the intent of this standard are truncated domes meeting the technical specifications of TAS 4.29.2.

Other textures such as grooves 1/4" deep and 3/4” wide 2" apart and arranged so that water will not accumulate, may be acceptable provided the surfaces are detectable underfoot. Other designs for surfaces that are detectable underfoot may be submitted for consideration.

02/16/09


CURB RAMP SURFACE

TECHNICAL MEMORANDUM 08-01

With the intention of harmonizing both state and federal requirements…

Curb Ramps NOT in the Public Right of Way

All curb ramps that are constructed, renovated, modified, or altered, but

are NOT within the public right-of-way must comply with TAS 4.7. 08-01

The detectable warning surface must extend the full width and depth of

the curb ramp (or landing as applicable at parallel curb ramps). The

Department strongly encourages the use of truncated domes complying

with TAS 4.29.2 as a means to satisfy both the state and federal

requirements in lieu of the surface textures listed under TAS 4.7.4(1). The

requirements set forth in TAS 4.7.4(2) will also apply to the full width and

depth of the curb ramp (or landing) as applicable.

This technical memorandum supersedes TM 99-15 issued in July 1999 and

which is no longer effective.

…it is important to note that simply satisfying the requirements of TAS does

not alleviate compliance with federal law.

ALARMS

TECHNICAL MEMORANDUM TM 99-17

Emergency warning systems provided within private offices used only by

employees as work areas are not subject to the provisions of TAS 4.1.3(14)

nor are they required to comply with TAS 4.287. This is for individual,

enclosed, private offices containing on employee workstation. This

interpretation is in accordance with the provisions of TAS 4.1.1(3) Areas

Used Only by Employees as Work Areas.

Break rooms, toilet rooms, training rooms, conference rooms, occupiable

storage rooms and any other common use spaces -- while perhaps used

only by employees -- are not exempted areas and are subject to

compliance to TAS 4.1.3(14) and 4.28. This may include open office areas

containing two or more employee workstations.

ALARMS

TECHNICAL MEMORANDUM TM 02-03

The TAS technical requirements for alarms is based on the ADAAG as

originally written. Because there have been advances in technologies

and changes in other codes governing alarms and life safety, TDLR finds it

necessary to begin recognizing and accepting compliance with other

codes in regards to alarms. Also taken into consideration is the proposed

technical requirements for the updated ADAAG. Therefore, audible and

visual alarms complying with NFPA72-1999, Chapter 4, will be acceptable

for compliance with TAS except that the maximum allowable sound level

of audible notification appliances complying with section 4-3.2.1 shall

have a sound level no more than 110db at the minimum hearing distance

from the audible appliance. Adherence to TAS 4.28 is still, also

acceptable for compliance with the TABA.

This new position is allowed by TAS 2.2 Equivalent Facilitation, however, a

Variance Application will not be required to be submitted to TDLR.
