MEMORANDUM
TO: Jim Witt, City Manager
FROM: Ken Griffin, P. E., Director of Engineering /Public Works Li
DATE: October 30, 2006
REF: Town Center Crosswalk
I have reviewed the Engineering Report from Kimley -Horn and have tried to reduce the study to
the key points. I also visited the site to ensure that recommendations were feasible and inclusive
of improvements that could be made to help inform the crossing pedestrian.
I broke down the report and my observations into three categories — Short Term Items, Long
Term Items and Other Items. Short term items are ones that we are currently working on and
should complete in the coming weeks. Long term items are ones that should be considered but
could be delayed for reasons such as: purchasing material, permitting through the state, design,
etc. Other items are ones that will need Council action and require a significant monetary
investment beyond the City Manager's authority and could be implemented if the short and long
term items fail to accomplish the desired goal.
Short Term Items:
VI) Stripe crosswalk on south side of intersection;
• Re- stripe stop bars at all legs of the intersection;
3) Replace PED lights with "countdown" PED lights; 3 °O
v4) Remove PED buttons and PED lights for the north side crosswalk and place signs that state
"No Pedestrian Crossing ";
✓S) Place information signs at PED buttons that explain various phases of PED light - enter,
continue to cross and do not enter (already placed);
6) Increase walk time for crosswalk. Current time is based on 3.7 feet per second and provides
7 seconds to enter the crosswalk and 28 seconds to cross for a total of 35 seconds. The revised
time will be based on 3.5 feet per second and will provide 7 seconds to enter the crosswalk and
35 seconds to cross for a total of 42 seconds.
7) Relocate the PED button at the SW corner of Town Center and Denton Tap from the east side
of the pole to the west side;
8) Remove the old PED button signs and lower the new PED information signs to eye level;
Nz9) Increase the all red time from 1.5 seconds to 2 seconds.
10) Work with High School to place articles in next issue of newspaper and get information on
KCBY.
Long Term Items:
1) Provide a 5 foot high decorative metal fence, with a mow strip, in the median of Denton Tap
from Town Center south to the Wendy's driveway (about 600 feet) and north of Town Center
toward Kingsridge a distance of about 100 feet. This would eliminate the opportunity to cross
Denton Tap except at the Town Center intersection.
2) Relocate east crosswalk further west by modifying existing ramps and median nose;
3) Relocate or add additional PED buttons. (Both 2 & 3 may require submittal to the State for
ADA considerations);
4) Replace existing PED buttons with ones that light up when activated (similar to an elevator
button) and ones that provide an audible sound;
5) Restudy and revise coordination of traffic signals on Denton Tap based on changes to
crosswalk times.
Other Items:
1) Create a "reduced speed zone" from Natches Trace to Sandy Lake, a distance of about 5700
feet. The "reduced speed zone " would lower the speed limit on Denton Tap from 40 mph to 30
mph from 2:50 pm to 4:20 pm. That time frame is 15 minutes before Denton Creek Elementary
lets out and 30 minutes after the High School lets out. The changing of the speed limit during
that time frame would require Council action so it could be enforced by the Police Department.
Awareness of the "reduced speed zone" would be enhanced by the placement of about 13
flashing beacons. The large number of beacons needed is because of the length of the "reduced
speed zone" and the need to place flashing beacons north and south of the major intersecting
streets. Also, the creation of the "reduced speed zone" may require us to again reevaluate the
coordination of the traffic signals.
