City Secretary No. 50570
City Project No. 101311
Ms. Poudyal,
Due to additional services requested by the City as part of the referenced project,
James DeOtte Engineering, Inc. will perform the work outlined in the following
items:
Scope of Work
Project Management:
The number of meetings and number of required monthly SBE reports included in
the original scope of services has been exceeded. Additional services have been
included to provide for additional meetings and required monthly SBE reports.
Archeological Services:
This project is subject to the Antiquities Code of Texas and also Section 106 of the
National Historic Preservation Act due to the U.S. Army Corps of Engineers Section
404 permitting process. After an initial review submittal to Texas Historical
Commission (THC), they have requested an archeological survey of the proposed
alignments.
To satisfy this requirement, field investigations will be conducted as a combination
of reconnaissance and intensive survey, consisting of pedestrian walk-over and
deep mechanical trenching within the floodplain. The soils and setting are
conducive to containing deeply buried surfaces (paleosols) and archeological
deposits; therefore, an estimated 1 1 trenches (between the 2 alignments) will be

excavated at least 30 feet (9 meters) long and to a maximum depth of 20 feet (b
meters), if feasible. Field methods will comply with the guidelines for archeological
survey as developed by the Council of Texas Archeologists (CTA) and approved
by THC. This investigation will evaluate archeological resources for their potential
eligibility for inclusion in the NRHP or designation as a SAL under the provisions of
the Texas Antiquities Code. Detailed notes and photographs will be taken
throughout the survey. A draft report of all results, including preliminary NRHP/SAL
evaluations of any identified archeological resources and complying with THC
and CTA guidelines will be submitted to the City and THC for review. Once THC
concurrence has been received, a final report will be submitted as per the terms
of the approved archeological permit.
Survey Services:
The City requested an adjustment in the south gravity alignment to relocate a
portion of the alignment from beneath a dump fill area containing mostly broken
reinforced concrete over 20 feet tall to a location outside this fill area. This area
is beyond the limits of the original survey and additional efforts are necessary to
gather the field topography along this City requested alignment adjustment.
Subsurface Utility Engineering (SUE):
The City requested we pursue additional SUE services to locate six utilities previous
not found. Three utilities on the north adjustment and three on the south
alignment. For the deeper utilities on the south alignment, a CDL Truck will be
utilized to locate the utilities or to a depth that verifies no utilities are present that
would conflict with the proposed sewer line profile elevation.
Construction Phase Services - Public Meeting:
The City requested we participate in a separate public meeting for the north
adjustment and the south alignment. Our original scope of services only included
one public meeting. This would provide for one additional public meeting.
