ST9302-UP000301I SANDY LAKE ROAD CONSTRUCTION I I Progress Meeting Held The City has continued holding progress meetings with the contractor during the latter part of 1999 and early part of 2000. The discussion at each of those progress meetings was coordination of the lowering of the City of Dallas' water line that currently exists in Sandy Lake Road. Representatives from Dallas Water Utilities and Upper Trinity River Authority were present at the November through March meetings to discuss coordination efforts. Utili~ Relocations The only major utility now left to be relocated is the City of Dallas' water line. The latter part of 1999 and the early part of 2000 was spent in coordination efforts with Dallas Water Utilities, Upper Trinity River Authority and the cities of Lewisville, Flower Mound and Coppell on how best to lower the City of Dallas' water lineo The water line in Sandy Lake Road provides 10 million gallons of water per day to the Town of Flower Mound and an emergency water supply to the City of Lewisvilleo The Upper Trinity River Authority also supplies 10 million gallons of water per day to the Town of Flower Mound. To continue with the construction of Sandy Lake Road, four separate portions of the water line needed to be lowered between Moore Road and Denton Tap and one long section of the water line needed to be lowered between Samuel and MacArthur. Lowering the water line requires the water line to be taken out of service so that connections can be made. The timeline provided to the City of Coppell was that the work had to be completed no later than March or early April. Once approval was given for the shutdown by all involved entities, the real issues were fabricating the materials for the lowering of the water line, delivery of those materials, installing the lowered portion and getting ready to make the actual tie-in to the existing water line. Before any of that work could commence, all traffic on the existing asphalt roadway had to be shifted to the new concrete section between Denton Tap and Moore. So while the critical timeline was approaching, the work could not commence until after the first of the year. Once traffic was switched, the old asphalt was removed~ the existing water line for the City of Dallas was exposed in numerous locations to verify actual limits of lowering and then pipe was fabricated. If the work was not performed by late March or early April, the work would not be allowed to be performed until winter 2000. This meant that at some point in late spring all construction on Sandy Lake Road would come to a halt waiting for the opportunity to lower the City of Dallas' water line in winter 2000. From the first of my involvement in 1993, the lowering of the City of Dallas' water line has always been identified as the critical component of this project. The entire construction sequence up to this point has been leading up to a coordinated effort to lower the City of Dallas' water line while maintaining a water supply to the Town of Flower Mound. March 2000 Project ST 93-02 Ken Griffin, Director of Engineering Denton Tap to MacArthur Since Last Update Work began on the lowering of the City of Dallas' water line in February 2000. The four sections to be lowered were at Heather Glen, Heartz, Lodge and Moore. The two lowerings at Moore and Heartz could not take place without closing off the intersections due to the depth of the lowering and the existing utilities. During spring break, we allowed the contractor to close Moore and Heartz to lower those sections of the City of Dallas' water line. I am happy to report that during the week of March 13-17, 2000, the contractor made two tie-ins to the City of Dallas' water line at Heatherglen and Lodge, and installed the new waterline through the intersection of Heartz and Moore. All work associated with the City of Dallas' water line to date has gone flawlessly. At the March 21, 2000 progress meeting it was noted that the next City of Dallas shut down is scheduled for Monday, April 3, 2000. At that time the contractor is scheduled to make the last two tie-ins into the City of Dallas' water line between Moore and Denton Tap. Complaints / Concerns Over the last few months I have been meeting with Homeowner Association groups to discuss landscaping/irrigation along the north side of Sandy Lake Road from Denton Tap to Moore. It is the City's goal to bring about the repair of all the damaged irrigation systems along the north side of Sandy Lake Road between Denton Tap and Moore so that the HOA's can irrigate the parkway areas this growing season. In the Future In the very near future the contractor will be completing the sidewalk along the north side of Sandy Lake from Denton Tap to Moore. He will also begin the facing off of the concrete retaining walls. It is the City's goal to select a single material that will coordinate with both the existing walls and brick pavers throughout the entire project. The contractor will also be completing additional drainage installations along the south side of Sandy Lake and March 2000 Ken Griffin, Director of Engineering continuing to install the 30" water line through the MacArthur intersection into the City of Coppell's pump station at Kimbel Court and Village Parkway. Motorists should expect some delays through the MacArthur intersection as the 30" water line is being installed. The City is attempting to get the water line in service prior to May 15, 2000 as it will provide greater volumes of water to the new elevated tank on the west side of Coppell. Below is a general outline of future sequences of paving as provided by the contractor: · Both north side lanes (Moore to Samuel) · Half of the north lane (Samuel to MacArthur) (westbound traffic, MacArthur to Moore, will be transferred to the new paving/eastbound traffic, Moore to MacArthur, will remain on existing asphalt) · Half of the south lane (Samuel to MacArthur) (eastbound traffic will be transferred to the new paving and the existing asphalt paving from Moore to MacArthur will be removed) · Both south side lanes (Denton Tap-Samuel) · Remainder of north lanes (Samuel- MacArthur) · Remainder of south lanes (Moore- MacArthur) The estimated timeline for completion is still in the summer 2001 timeframe.
