RE: Bethel Road - Addendum #2
TranSystems Project No. 20000890
Dear Mr. Griffin:
This is an additional fee request for additional survey and environmental work associated with
the proposed channel improvements between Freeport Parkway and Coppell Road. The
additional work is smnmarized below:
Additional Survey For Drainage Easements and Additional Topography
. Field preparation, field work and boundary resolution associated with locating property
comers for the expected 10 drainage easements between Freeport Parkway and Coppell
Road (2 on the south side of Bethel Road and 8 on the north side of Bethel Road).
Multiple property comers for 6 of the parcels on the north side of Bethel Road resulted in
additional office time and return trips to the field.
. Additional topography beyond the top of the creek bank is required to complete the
channel improvement design. This is in addition to the topographic data collected for the
original Hydraulic Study. This topographic survey involved setting numerous control
points in order to see over fences and into back yards abutting the west Side of the creek.
In order to conduct the topographic survey on the south side of Bethel Road, additional
control also had to be set due to the loss of onginal control from recent development on
the north side of Bethel Road.
. Easement documents for the 10 drainage easements will be completed once the final
channel alignment has been determined. We estimate there will be close to 30 easement
comers marking the 10 easements due to the configuration of the creek.
. Additional topographic survey data is required for the extension of Freeport Parkway
north of Bethel Road. This extension of Freeport Parkway was constructed followmg the
original topographic survey of the area.

flag the jurisdictional boundaries (waters of the United States) associated with the
channel improvements between Freeport Parkway and Coppell Road. The sub-consultants
proposal is attached.
