On cover sheet - show proper location of 30" water line. Show
12" water line on north side of Sandy Lake Road. Why is ROFC
being built in this location? Why not utilize location better
to provide space for future facilities.
Sheet 2 - Need floodplain permit for fill area. Study will
need to be done. Flex base will not be allowed, concrete
drive surface only.
Sheet 3 - Need to match engress/egress with future Sandy Lake
Road paving.
Sheet 9 - Need to add enclosure for Coppell's equipment to
monitor Dallas flow.
Driveway and parking lot should be 6" concrete with 6"
stabilized subgrade as per the city's Standard Detail.
This site was not part of the Riverchase reclamation. A flood
study and floodplain permit should be provided for the fill
and fence. A floodplain map has been provided for your use.
Sandy Lake Road is currently under design by Sverdrup Corp.
through Dallas County and the project is scheduled to begin in
late 1995. Attached are copies of the preliminary cross
section and plan and profile sheets showing the proposed
grades of Sandy Lake Road.
The typical channel cross section on Sheet 4 needs to show the
approximate width of pilot channel and a note stating it will
be concrete.
