The Federal requirements are found in the Americans with Disabilities Act Title II Regulations dated September 15, 2010. The State requirements are located in California Code of Regulations Title 24; 2016 California Building Code (CBC) at Chapter 11B. While the Federal regulations include many facility requirements, they also include program and employment rules which are beyond the scope of this assessment. The Federal facility related requirements are found in the 2010 ADA Standards for Accessible Design (ADAS). Chapter 11B is modeled after the 2010 ADAS and includes many California additions. For the purpose of this Assessment, Chapter 11B of the 2016 CBC will be the Standard. Scope of Work Perform a site visit to two street intersections to observe existing site and conditions in accordance with BKF’s proposal dated November 19, 2018. See description of intersections below. The site visits were performed on November 6, 2019. An assessment was performed of site and building features relative to the Standard. Measurements were obtained with the use of a “SmartLevel” and a steel tape. This Assessment is intended to identify features which do not meet the Standard. While an attempt has been made to identify each feature which does not meet the Standard, no warranty is expressed or implied that all were discovered. For example, the Assessment includes measurement of pathway slopes at various locations. While an attempt has been made to identify and measure each condition which may not meet the Standard, it is beyond the scope of this Assessment to measure each and every location. It should be noted that in general, facilities are required to comply with the requirements in effect on the day they were initially constructed. When an alteration occurs, the alteration and certain paths of travel, must meet the most recent requirements. This Assessment does not take date of construction or alteration into account. As a result, it is possible that a more stringent Standard than necessary for “compliance” with State and Federal ADA requirements have been applied. Page 1 How to Read this Assessment The Assessment is organized into three parts. 1. Part one includes Key Maps which show the location of the various features which do not meet the Standard. 2. Part two is the list of various site and building features (referenced by number to the Key Maps and Photos) which do not meet the Standard along with a reference to the 2016 CBC requirement and the actual measured condition. 3. Part three includes photos of the features which do not meet the Standard. List of Intersections Assessed 1. Big Basin Way and Saratoga-Sunnyvale Rd. (all corners except SW) 2.
