ATTENDANCE: Ken Griffin, P.E., Dir. of Engineering & Public Works – City of Coppell Suzan Taylor, C.I.P. Coordinator – City of Coppell Mike Jones, P.E. – TNP Fort Worth Office Jay Volk, P.E. – TNP Dallas Office Mark Holliday, P.E. – TNP Dallas Office Matt Atkins, Graduate Engineer – TNP Dallas Office Meeting w/ City of Coppell Friday, February 28, 2003 Update Design Schedule Phase 1 – (Project ST 99-02 A) State Highway 121 to State Road Construction is anticipated to start in mid 2004 according to the City’s website. Still current. Complete Preliminary Design – August 1, 2003 Okay Complete City Review – September 1, 2003 Okay Complete Final Design – December 1, 2003 Okay Begin R/W Acquisition – October 1, 2003 The City would like to begin acquisition as soon as possible for Phase 1, since it may take a year. Phase 2 will be addressed later. The City provided TNP with a copy of the final plat for Amberpoint showing dedication along Sandy Lake Road and State Road. Begin Utility Relocations – January 1, 2004 Schedule as shown is acceptable. Phase 2 – (Project ST 99-02 B) State Road to Denton Tap Road 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 Complete Preliminary Design Complete City Review Complete Final Design Begin R/W Acquisition Begin Utility Relocations Schedule for Phase 2 to be developed later. Public Meeting Date/Location Information/Exh ibits 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. Discussion of Schematic Design Report and Plans – Phase 1 Issues Proposed Roadway Section: 6-Lane Divided; minimum r/w width-110 feet 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. Left turn lanes need to be 11-feet wide. The schematic plans showed this width to be 10-feet. Proposed Pavement Section: 8-inch reinforced concrete pavement/8-inch lime stabilized subgrade. Lime application rate should be 42#/SY (min.); reinforcing should be the City’s standard of #3 bars at 24” O.C.E.W. Horizontal Alignment 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. w/super-elevation: 40-42 mph w/o: 35-37 mph 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 immediately east of Coppell Road North at an appropriate transition point. Roadway and drainage improvements may not terminate at the same location. Status of MIS for State Highway 121 - Still in EA review. Proximity to north R/W 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. 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). Vertical Alignment TNP to check cut/fill 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. Signalization Royal Lane? Yes. State Road? Not likely to need traffic signalization with this project. Design will provide for conduit only. Coppell Road North? Yes 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. Royal Lane Include construction of southbound lanes and divided median? Yes. Median width shall be 36.5’ as shown in our plans. Sidewalk Construction? Sidewalk will not be shown along the north side of the roadway, west of Freeport Parkway. 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. Sidewalks should not overlap inlet tops. 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/W and TXU transmission towers. 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. The roadway trail crossing at Coppell Road North needs further evaluation and discussion to make sure that it is not impeded by vehicles that are stopped at the intersection. 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. 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. Other City Review Comments 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. The City provided a mark-up set with additional comments. TNP to Confirm that drainage areas are consistent with proposed improvements in areas of superelevation. 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. Discussion of Schematic Design Report and Plans – Phase 2 Issues 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. Proposed Pavement Section: 8-inch reinforced concrete pavement/8-inch lime stabilized subgrade. Lime application rate should be 42#/SY (min.); reinforcing should be the City’s standard of #3 bars at 24” O.C.E.W. Horizontal Alignment 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. w/super-elevation: 45-47 mph w/o: 40-42 mph Conflict w/TXU Transmission Poles. The City acknowledged that up to four poles would need to be relocated. Tree Preservation/Removal 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. Bridge conflict w/ 24-Inch Water Line. This item was not addressed at the meeting. Vertical Alignment Retaining Walls TNP to clarify the maximum wall height required. The schematic report indicates that the maximum is 11 feet, however, the plans show the maximum height to be only 8 feet. 24-Inch Water Line Adjustment This item was not discussed at the meeting.
