i. Construction is anticipated to start in mid 2007 according to the
City's website The schedule for Phase 2 could possibly be delayed
further depending on future budget restraints
ii. Complete Preliminary Design
iii. Complete City Review
iv. Complete Final Design
v. Begin RIW Acquisition
vi. Begin Utility Relocations
Schedule for Phase 2 to be developed later.
II. Public Meeting
a. Date/Location
b. Infonmation/Exhibits
c. Format
Additional funding from Dallas County is being sought by the City and if
approved public hearings will be necessary. Also, the City may hold their
own "neighborhood meetings" for Phase 1 and/or Phase 2.
III. Discussion of Schematic Design Report and Plans - Phase 1 Issues
a. Proposed Roadway Section: 6-Lane Divided; minimum r/wwidth-110 feet
i. Phase 1 will consist of the design and construction of the outside
four-lanes of an ultimate six-lane divided roadway, instead of the full
six-lane section. The proposed median width for Phase 1 will be 40-
feet to accommodate the future construction of one additional lane in
each direction. Storm drainage facilities will be designed for the
ultimate six lanes of pavement.
ii.Left turn lanes need to be 11-feet wide. The schematic plans
showed this width to be 10-feet.
b. Proposed Pavement Section: 8-inch reinforced concrete pavement/8-inch
lime stabilized subgrade. Lime application rate should be 42#1SY (min.);
reinforcing should be the City's standard of #3 bars at 24" O. C. E. W.
c. Horizontal Alignment
i. Super-elevation/design speed - Coppell Road North The City and
TNP discussed the super-elevation at Coppell Road North, but never
developed a clear consensus about whether or not the design speed
was acceptable. Some discussion focused on the City's interest in
the possibility of raising the roadway grade in this area, however, the
existing retaining wall on the north side of the roadway (east of
Coppell Road North) may prevent this from being practical. The City
will provide existing plans for the retaining wall to TNP for evaluation.
TNP will then look at options, if any, for the horizontal and vertical
alignment in this area and discuss them again with the City.
a. w/super-elevation: 40-42 mph
b. w/o: 35-37 mph
ii. Limits of improvements (west end and east end). The west limits
shall be as shown on the schematic plans. The east end limits will be
Page 2 01 6
Suzan Taylor - meeting notes 02-28-03 final.doc
Page 3
immediately east of Coppell Road North at an appropriate transition
point. Roadway and drainage improvements may not terminate at
the same location.
iii. Status of MIS for State Highway 121 - Still in EA review.
iv. Proximity to north R1W line & TXU Overhead Transmission
Towers - OK, but TNP to look at the impact of proposed cut (and/or
fill) on the TXU tower foundations and discuss with TXU to determine
if they will have any concerns.
v. Transition from 6-lanes to 4-lanes and vice-versa - Concept is
OK but TNP to evaluate and revise transition based upon the
proposed design of only the outside 4-lanes west of Freeport
Parkway (State Road).
d. Vertical Alignment
TNP to check cutlfill slopes in cross-sections. Minimum slope shall be 4:1.
City will obtain slope easements or permission to grade, as necessary.
See notes under IIIc(i) 1 above.
e. Signalization
i. Royal Lane? Yes.
ii. State Road? Not likely to need traffic signalization with this project.
Design will provide for conduit only.
iii. Coppell Road North? Yes
f Survey of Outfall Drainage (north of W. Sandy Lake Road) TNP advised
City of inability to obtain permission to get access to some properties for
survey. City will contact property owners to get permission.
g. Royal Lane
i. Include construction of southbound lanes and divided median?
Yes.
ii. Median width shall be 36.5' as shown in our plans.
h. Sidewalk Construction?
i. Sidewalk will not be shown along the north side of the roadway, west
of Freeport Parkway.
ii.Sidewalk on the south side should be set back from curb at least 2-
feet, where possible. Any sidewalks adjacent to back of curb need to
be 6-feet in width.
iii. Sidewalks should not overlap inlet tops.
iv. The City wants the proposed hike/bike trail to be extended from
Coppell Road North to Freeport Parkway and south on Freeport
Parkway. The City would prefer the trail to be designed and
constructed on the north side of the roadway in this area, but that
may not be possible because of limited R/VV and TXU transmission
towers.
v. The City would prefer that the proposed hike/bike trail to the east
of Coppell Road North, along the south side of the roadway, be
moved away from the back of curb by at least 3 feet. The trail width
could be reduced from 10 feet to 8 feet, if necessary, to help facilitate
this adjustment.
vi. The roadway trail crossing at Coppell Road North needs further
Page 3 01 6
SUlan Taylor - meeting notes 02-28-03 final.doc
Page 4
evaluation and discussion to make sure that it is not impeded by
vehicles that are stopped at the intersection.
vii. There may be some issues related to the proposed trail alignment
where it is shown outside of the proposed or existing RIW. Some of
these areas are controlled by the HOAs, not the City.
viii. TNP to schedule a meeting in the near future with NJB and the
City to discuss the trail extension, the trail alignment, roadway
crossings and other issues related to the proposed sidewalk and trail
systems.
i. Other City Review Comments
i. The City's review comments will be evaluated and addressed by TNP
and a detailed response provided to the City at a later date. The City
provided a written list of comments dated March 27, 2002.
ii. The City provided a mark-up set with additional comments.
iii. TNP to Confirm that drainage areas are consistent with proposed
improvements in areas of superelevation.
iv. Refer to city comments and mark-up for additional left turn lane
and drive approach needs. The City's review comments will be
evaluated and addressed by TNP and a detailed response provided
to the City at a later date.
IV. Discussion of Schematic Design Report and Plans - Phase 2 Issues
a. Proposed Roadway Section: 4-Lane Divided; minimum r/w width-90 feet
Left turn lanes need to be 11-feet wide. The schematic plans showed this
width to be 10-feet.
b. Proposed Pavement Section: 8-inch reinforced concrete pavement/8-inch
lime stabilized subgrade. Lime application rate should be 42#1SY (min.);
reinforcing should be the City's standard of #3 bars at 24" O. C.E. W.
c. Horizontal Alignment
i. Super-elevation/design speed - Coppell Road South The City and
TNP discussed very briefly the super-elevation at Coppell Road
South, but never developed a clear consensus about whether or not
the design speed was acceptable. TNP and City will need to re-visit
this issue before proceeding with the preliminary design of Phase 2.
a. w/super-elevation: 45-47 mph
b. w/o: 40-42 mph
ii. Conflict wlTXU Transmission Poles. The City acknowledged that
up to four poles would need to be relocated.
iii. Tree Preservation/Removal
1. 4-Lane Divided vs. 4-Lane Undivided. The City prefers that
the 4-lane divided alternative be designed and constructed. A
final decision will be needed from the City before TNP
proceeds with preliminary design of Phase 2.
iv. Bridge conflict wi 24-lnch Water Line. This item was not
addressed at the meeting.
d. Vertical Alignment
i. Retaining Walls TNP to clarify the maximum wall height required.
Page 4016
Suzan Taylor - meeting notes 02-28-03 final.doc
Page 5
The schematic report indicates that the maximum is 11 feet, however,
the plans show the maximum height to be only 8 feet.
ii. 24-lnch Water Line Adjustment This item was not discussed at
the meeting.
iii. Lone Star Pipeline Adjustment. The City instructed TNP to make
every possible effort to avoid having to lower the pipeline due to the
significant cost of such an adjustment (in excess of $300,000). TNP
to adjust proposed roadway grades to clear the existing line, even if
retaining walls are required. TNP to consider creative approaches to
storm drain crossing, as necessary, to avoid conflict.
e. Signalization
i. Coppell Road South? Yes
ii.A new traffic signal may be added at Whispering Hills Drive. The City
is currently conducting a warrant study. If a traffic signal design is
necessary, TNP's contract will be amended accordingly.
f. SidewalklTrail Construction?
i. Sidewalks should be set back from curb at least 2-feet, where
possible. Any sidewalks adjacent to back of curb need to be 6-feet in
width.
ii.Sidewalks should not overlap inlet tops.
iii. The City would prefer that the proposed hike/bike trail be moved
away from the back of curb by at least 3 feet. The trail width could be
reduced from 10 feet to 8 feet, if necessary, to help accomplish this
adjustment.
iv. There may be some issues related to the proposed trail alignment
where it is shown outside of the proposed or existing R/W. Some of
these areas are controlled by the HOAs, not the City.
v. All roadway trail crossings need further evaluation and discussion
to make sure that they are not impeded by vehicles that are stopped
at the intersection.
vi. TNP to schedule a meeting in the near future with NJB, and the
City to discuss the trail alignment, roadway crossings and other
issues related to the proposed sidewalk and trail systems.
g. Other City Review Comments
i. The City provided a written list of comments dated March 27, 2002.
ii. The City provided a mark-up set with additional comments.
iii. The proposed lighting on the bridge over Cottonwood Branch
should be consistent with the existing bridge on Denton Tap Road.
iv. Confirm that drainage areas are consistent with proposed
improvements in areas of superelevation.
v.
vi. Refer to city comments and mark-up for additional left turn lane
and drive approach needs.
vii. The City's review comments will be evaluated and addressed by
TNP and a detailed response provided to the City at a later date.

V. Landscape/Streetscape Design
a. Stamped concrete is to be used in lieu of pavers.
b. The City has recently implemented new landscapelstreetscape concepts for
city-maintained medians, in an effort to reduce maintenance costs and
reduce watering requirements. Depending on the public reaction to and
success of the current project on Sandy Lake Road between MacArthur
Blvd. and Denton- Tap Road, TNP may be asked to design something
similar for this project. The City will provide landscape plans for the current
project to TNP for our information and use.
c. TNP to schedule a meeting in the near future with NJB and the City to
discuss the proposed landscapelstreetscape design for W. Sandy Lake
Road in more detail.
VI. Supplemental Surveys
a. TNP will need to update the project base map to reflect trees along Phase 1
that were removed with recent development.
b. TNP to evaluate the need for supplemental surveys on Phase 1 to reflect
new development between Royal Lane and Freeport Parkway and the new
church site at the southeast corner of Freeport Pkwy and W. Sandy Lake
Road. Construction plans and site plans will be provided by the City and
used, if possible.
c. Supplemental design surveys will be needed for Phase 2 prior to proceeding
with design, but these will be postponed until a later date.
d. Additional field surveys will be needed at the Denton Tap Road intersection
to tie down the new widening that was constructed on the east side of the
intersection.
VII. Updated AeriallTopographic/GIS Information
TNP will contact Eddie Johnson in the GIS department to obtain latest
topographic information.
VIII. Utility Coordination
IX. M~ce"aneous
a. TNP will conduct regular project team meetings with the City as design
progresses.
