RE: Consideration of approval of the Sandy Lake Road preliminary construction
plans and landscape plans and authorizing the City Engineer to instruct the
consultant to proceed with the f'mal design.
Date: March 18, 1996
On May 9, 1995, City Council authorized Rady and Associates to proceed with the redesign of
Sandy Lake Road by shifting the roadway approximately 10 feet to the north to avoid the
existing TU Transmission poles. Staff has been working with the consultant, by virtue of
attending monthly meetings, to discuss various aspects of the project and is now in a position
to recommend approval of the preliminary plans so that the design of the final construction plans
can begin. The shifting of the roadway north has not created an appreciable difference between
this design and the previous design in regards to the roadway itself, however, it has made an
impact in regards to the landscaping. The major change in the landscaping plans has been that
instead of now having strong definition along the outer edges with taller trees, plants, etc., and
shorter plantings in the median section we are not proposing a strong definition along the center
median because of the lack of the additional right-of-way on the north side. In reviewing the
landscape plans, you will still notice that the City has been able to provide a very nice
aesthetically pleasing landscaped project even with the reduced right-of-way on the north side.
The landscape consultant has been very sensitive to existing improvements and has attempted
to incorporate those into his landscape scheme. All in all, the landscaping will exceed the
landscaping we currently have on roadways such as Denton Tap and MacArthur Blvd. and will
be an aesthetic amenity to the City.
Included with this agenda item is the latest opinion of probable construction cost from Rady and
Associates dated March 4, 1996. This information is provided to keep Council apprised of the
anticipated cost, especially as we proceed with final plans and the need to secure the funding to
construct the project.
The project itself is broken down into three phases:
1. Paving and Drainage: estimated at $4,500,000,
2. Construction of a portion of our Water Master Plan down Sandy Lake Road (this
includes the lowering of approximately 5000 feet of the existing 30" City of
Dallas water line): estimated at $2,000,000,
3 Landscaping, irrigation and channel improvements at the southwest corner of
MacArthur and Sandy Lake: estimated at $2,000,000. (It should be noted that
the channel work only includes the corner of Sandy Lake and MacArthur and
does not include the section of channel south to Mapleleaf. That section is
already calculated into the paving and drainage cost under items 52 and 53.).
The total estimated cost of this project, with contingencies, is approximately $9,500,000. Of
that amount, approximately $500,000 will be reimbursed by the City of Dallas for lowering the
30" water line. The time table for the construction is still not resolved. However, depending
on either Flower Mound's acquisition of an alternate water supply or our ability to work out a
plan to provide Flower Mound with water, this project could commence as early as winter of
1996. If the City is unable to work out the water issue with the Town of Flower Mound, then
more than likely the construction will commence in mid to late 1997. Some funds will still need
to be provided in 1996 to begin the process of acquisition of necessary right-of-way and the
relocation of any utilities which can be accomplished at this time.
Staff recommends approval of the preliminary plans and preliminary landscape plans and will
be available to answer any questions at the Council meeting.
