I. Review Revised Alignment - The revised horizontal and vertical alignments

Road North and Winding Hollow. The City did not express any concerns about the
new alignments.
A. Horizontal Alignment from State Road to Winding Hollow
B. Vertical Alignment from State Road to Winding Hollow
C. Cross Sections showing existing retaining wall
It was noted that the new vertical alignment results in retaining walls as much
as ten feet in height in phase two of the project. The style and design of the
walls will be discussed more in future meetings.
D. Right-of-way in front of Oakbend & Branchwood
The right-of-way taking along these lots will be to a point 13 feet back of curb to
allow for a four foot landscape strip, an eight foot trail and one foot clear space.
The right-of-way taking should not encroach beyond the existing landscape
buffer.
II. ADA Issues - TNP will schedule a meeting with Kristi Thomas of Accesso/ogy
(972-434-0068) to discuss ADA issues prior to submittal of preliminary plans.
