This presentation will identify the compliance requirements of the 2012 Texas Accessibility Standards (TAS).
The elements and spaces to be discussed during this presentation are addressed in Chapter 3 and in limited cases, Chapter 2, of the 2012 TAS and include the following:
The provisions of Chapter 3 shall apply where required by Chapter 2 or where referenced by a requirement in this document (301.1).
Defined as: Elements or components contributing to a plan or system. 308 Reach Ranges 309 Operable Parts 304 Turning Space 305 Clear Floor or Ground Space 306 Knee and Toe Clearance 307 Protruding Objects 302 Floor or Ground Surfaces 303 Changes in Level The components of Chapter 3 create the basic system for building accessible rooms, elements, and spaces.
Floor or ground surfaces shall be stable, firm, and slip resistant and shall comply with 302. The following excerpts from Advisory address the minimum requirements for stable, firm, and slip resistant surfaces.
One that remains unchanged by contaminants or applied force, so that when the contaminant or force is removed, the surface returns to its original condition. Grass and sod surfaces are not prohibited, however, they typically will not meet this criteria. What is a stable surface?
One that resists deformation by either indentations or particles moving on its surface. Soft or loose materials such as sand, gravel, bark, mulch, or wood chips surfaces do not meet this criteria. What is a firm surface?
One that provides sufficient frictional counterforce to the forces exerted in walking to permit safe ambulation. Slip resistance is the most controversial and difficult to measure since there are many types of surfaces and testing methods and compliance is applicable when wet or dry. In 2009, the National Floor Safety Institute issued the ANSI/NFSI B101.1 which is a new national safety standard for testing dry, hard surfaces. What is slip resistance?
It was recommended to DOJ that they apply an American Society for Testing & Materials (ASTM) standard (with modifications) to the 2010 SAD to assess whether or not a floor surface is "slip resistant… DOJ declined the recommendation since there is no generally accepted test method for the slip-resistance of all walking surfaces under all conditions.
However, DOJ did include ASTM standards in the 2010 SAD applicable to safe surfaces under and around playground equipment. ASTM standards are referenced in: (Referenced Standards) (Play Areas: Ground Surfaces)
ADA-Certified TAS-Compliant ADA-Approved None…neither DOJ nor TDLR endorses or approves any products or manufacturers. Compliance is typically dependent on the installation and maintenance. What surfaces have the ADA /TAS – Seal of Approval?
(Concrete with small pebbles) Some factors that affect compliance with 302: Size of aggregate Tamping and leveling of the aggregate
Within animal containment areas, floor and ground surfaces shall not be required to be stable, firm, or slip resistant. Not applicable to public circulation routes where animals may travel, such as in petting zoos (Advisory ).

Unobstructed Forward Reach. 48 inches maximum and 15 inches minimum. A reach of 44 maximum and 16 minimum (as recommended for children) is not a violation of
Accessible elements and operable parts designed for adult use or children over age 12 can be located outside these ranges but shall be within the adult reach ranges.
Where a forward reach is unobstructed, the following is required: High Forward Reach: 48 inches maximum. Low Forward Reach: 15 inches minimum.
Where a high forward reach is over an obstruction, the clear floor space shall extend beneath the element for a distance not less than the required reach depth over the obstruction.
