Church Street Sidewalk Design Considerations Constraints: 7-4-2018 1. Limited ROW - The ROW is 40' wide from Hearne to Washington and from Kaufman to Clarksville. It is 45' to 50' wide from Washington to Kaufman. With a proposed 28' street, approximately 6' of parkway is available for sidewalks, utility poles, water meters, etc. 2. Franchise Utilities — AT&T and Oncor Electric both own and operate overhead utilities along Church St. Many of the old, existing poles encroach into the street curb, and were often hit by vehicles. Early in the design process, we considered relocation of the poles to the back side of the sidewalk to improve clearance to the poles. After an onsite project walk with the utility companies, it was decided that moving the poles would not be a desirable option because it would require the "topping" of many large trees in the front yards along Church. The poles must remain in a similar alignment to the existing poles, so all parties agreed that 18" from the back of the proposed curb could be achieved, optimizing the distance from the street while meeting ADA requirements for the sidewalk. For the areas with the most limited ROW width, the section below is proposed. ♦' SIDEWALK 6 1 1.6' 2- 3.5, o rP u I SIDEWALK 14 II "� � -,�.� � as � • I�. ;. � 1. 3. Accessibility Requirements of the ADA —The minimum clear width required to meet accessibility standards mandated by the Americans with Disabilities Act (enforced locally in the Texas Accessibility Standards) is 4' for a standard run of sidewalk, with turnarounds located every 200'. Where necessary, a width reduction is allowed for 32" minimum width for up to 24" maximum distance (considered a point constraint, such as a utility pole). Due to limited ROW, the sidewalk design utilizes this allowance.
