Denton Tap Road Improvement - Sight Distance Concern
Attached is a report from our Consulti~g ~ngineer, Ginn, Inc.,
regarding sight distance concerns expressed at the May 8, [990 City
Council meeting.
Our Consultant has reported that there is ample sight distance and
that the pole and monument sign in the area does not pose
significant visual obstructions.
The request to look at this area was brought up in discussion at
the time the Meadowcreek/Denton Tap median opening item was
discussed according to Public Works staff in attendance at th=~
council meeting.
Should you have any questions regarding this matter, please advise.

Re: Denton Tap Road Improvements from Sandy Lake to Denton Creek
Sight Distance Concern at Skagg's northernmost driveway
Dear Mr. Goram:
We recall that a question was raised during the April 24, 1990
city Council meeting by councilman Ron Robertson regarding an
obstruction to vision consisting of a wall and some utility
poles/structures adjacent to the driveway at the above referenced
location. We have prepared a sketch showing the locations of the
obstructions. Our review of the situation revealed that while
the wall (monument sign) and telephone pedestal do not pose
significant visual obstructions, the power pole does create a
partial visual obstruction for drivers wishing to enter Denton
Tap Road. This situation does not appear to be serious because
once a driver pulls his car forward to within two or three feet
of the curb line of Denton Tap Road, the visual obstruction is
gone.
We have also reviewed the situation regarding visibility for
northbound motorists turning left from Denton Tap Road into the
Connell/Skaggs Center. Our review indicates that there is ample
sight distance for the vehicles turning left into the center. We
received many complaints about visibility at this location while
the rye grass in the medians was excessively high. Now that the
grass has been cut, there does not seem to be any problems or
complaints.
We have revised the median landscape plans in this area to
prevent further problems. Also we suggest that no signs or
landscape features be allowed in the median within the first 150'
north of the median opening. As we have already seen, the grass
should be kept mowed in this area of the median.
Please call me if you have questions.
Sincerely,
· Karlsruher, P.E.
