On May 19, 2004, Environmental Access, Inc. conducted an onsite visit and survey of the Sherman County Elections Office for compliance with the ADA Accessibility Guidelines and Chapter 11 of the Oregon Structural Specialty Code, the accessibility requirements adopted by the State of Oregon.
Most election offices were located in their county courthouse. Therefore most of the surveys involved an evaluation of a portion of a larger facility. The scope of the survey included the accessible route from the public sidewalk and parking, if provided, to the accessible entrance. If the accessible route to the elections office included use of an elevator, the elevator was evaluated. In addition to surveying the public access areas of the elections office, employee and volunteer areas were evaluated. The survey also included an evaluation of the most accessible toilet facilities that served the elections office.
The purpose of the survey was to identify structural barriers to the county elections office so that the elections offices can evaluate and prioritize barrier removal and obtain financial assistance from the HAVA Program to assist with the funding of the removal of these barriers.
The recommendations provided in this report are made to assist the county elections office in identifying and removing structural barriers to its facilities. An evaluation of individual programs, services and activities within a certain facility was not part of this study. This report does not address potential program modifications that may be available to provide program accessibility. Public entities that are subject to Title II of the ADA must conduct an ADA compliance review known as an ADA Self Evaluation. The ADA Self Evaluation must include an evaluation of policies, practices, procedures, programs, employment, and communication as well as an evaluation of facilities for structural accessibility. As part of the ADA Self Evaluation, each public entity is required to develop an ADA Transition Plan to address any structural barriers identified during the ADA Self Evaluation process.
The ADA Compliance Report
Each report has an “Executive Summary” located at the beginning of the report that summarizes all of the recommendations made in the body of the report. The recommendations are prioritized in order of importance using the priorities established by the U.S. Department of Justice for public entities.
The body of the report utilizes three sections for each set of structural barriers identified. The first section is titled “Existing Condition.” The “existing condition” section summarizes the building element or elements that do not comply with either the ADA Accessibility Guidelines or the State of Oregon Building Code.
The second section is titled "ADA Accessibility Guidelines." The "ADA Accessibility Guidelines" section of the report is a summary of the applicable accessibility requirements, including the more stringent Oregon requirements where applicable. A complete copy of the ADA Accessibility Guidelines should be consulted along with the State of Oregon Building Code prior to making any alterations to the facility.
The third section is titled "Recommendations." The "recommendations" section provides a recommendation or recommendations for the removal of the architectural barriers identified. This section may also make a recommendation for an alternative to barrier removal or may make a recommendation for a temporary solution.
Photographs of barriers are provided in the appendix section of the report, which is located at the back of the report. The photographs are numbered and referenced in the body of the report by appendix page and photograph number. Not all barriers have photographs as many are clear and straightforward and therefore photographs were not included in the appendix of the report. New digital camera operator error also caused some photographs to be missing.
Some counties have provided drive-up drop boxes at their county courthouses or at other convenient locations within their county for voters to drive-up and drop their ballots without having to exit their vehicle. These drive-up drop boxes are excellent ways to provide improved access for people with disabilities and seniors. Because of the cost of removing many of the barriers identified during this survey, counties should consider providing these drive-up drop boxes as an alternative.
If, after reviewing the report, there are any questions about the barriers identified or the recommendations made, or any other aspect of the survey or report, please contact Bob Pike at Environmental Access, Inc.
