Dear Mr. Weiss:
Teague Nall and Perkins, Inc. is submitting this fee Amendment to the above referenced contract
based on additional services requested. The following is a brief description and cost for the
additional services provided on this project:
Additional Services to provide surveying and water line extension design for UNIT 2:

As requested, the right of way along Keller Hicks (Phase 2) will need to be surveyed
between Park Vista and the culverts to the east of the intersection to adequately evaluate
and design for acceptable drainage outfall. Also, survey of the area south of Keller Hicks,
near the Culverts in Bear Creek Meadows Subdivision will need to be acquired to design an
acceptable outfall for a drainage system along Keller Hicks. In addition, the right of way

ATTACHMENT`A'
SCOPE OF BASIC FOR HYDRAULICS/HYDROLOGY SERVICES
This project will consist of the evaluation and analysis of the culvert crossing at Keller-Hicks and Big Bear
Creek. The work will consist of analyzing the existing conditions at the site,sizing the proposed culvert,and
filing the necessary application for a conditional letter of map revision(CLOMR)and a letter of map revision
(LOMR).
Task 1 - Data Acquisition and Collection
The data collected for this Task includes existing information possessed by City of Fort
Worth in the form of studies, maps, engineering construction plans, and digital files as well
as information generated in the field specifically for this project. It is understood that
information obtained during the completion of this Task will include the information needed
to complete the work as described and is summarized as follows:
a. Obtain available topographic maps,zoning maps, use maps, and available"As-Built"
construction plans within the study limits. This data will be obtained from the City of
Fort Worth and will be used to supplement he field surveys.
b. Obtain and review existing CLOMR/LOMR's on file for the project area. The work is to
include a review of the documents and/or confirmation models. This Task will require
coordination and/or consultation with the City of Fort Worth and the Engineers
responsible for the existing CLOMR/LOMR's.
c. Obtain the "current effective" hydrologic/hydraulic models from the Federal Emergency
Management Agency(FEMA),for Big Bear Creek,including current LOMR's and CLOMR's
filed with FEMA and/or the City of Fort Worth.
d. Field survey work for this project will be performed under a separate scope and Task.
Task 2 - Hydrologic Analysis
This Task includes the work necessary to develop hydrologic models for Big Bear Creek
upstream of, and including,the existing culvert at Keller-Hicks Road. Study discharges will
be determined for the 2, 10, and 100-year storm events for ultimate and existing watershed
conditions. A summary of the work necessary for this task is as follows:
a. Prepare a drainage area map, using a reasonable standard scale,from available contour
maps provided by the City of Fort Worth.
b. Delineate sub-watersheds as necessary to analyze the existing drainage patterns within the
study area. These sub-watersheds will also be utilized to identify and define the proposed
improvements. The delineation of the sub-watersheds will be based on the drainage areas
of the existing storm sewer and surface runoff as defined by the available"As Builts". In the
absence of such data, the areas will be delineated based on available topographical
information provided by the City of Fort Worth.
Mr.Michael R.Weiss,PE,October 10,2007,Page 4 of 5
c. Create existing and ultimate condition models based on the hydrologic models
obtained from the City, (i.e. the Cities map-mod model). Review and/or confirm
hydrologic parameters in the existing model for each sub-watershed, including
precipitation data, time of concentration, composite SCS Curve Numbers, and
land use category. Upon confirmation of the parameters develop hydrologic
models in HEC-HMS format for the existing and ultimate watershed condition.
Task 3 - Hydraulic Analysis
This Task includes the work necessary to complete the hydraulic analysis of Big Bear Creek
within the study area. The work will utilize the HEC-RAS computer model and will consist
of the confirmation of the current effective model, development of the post-project model
and the delineation of the 100-year flood plain. The models will reflect the discharges
obtained in Task 2. A summary of the work necessary for this Task is as follows:
a. Review and confirm the current effective model in HEC-RAS format obtained from FEMA as
required for the application for a CLOMR/LOMR.
b. Create a corrected effective model to reflect the field surveyed cross-sections.
c. Utilizing the corrected effective model as a basis, recommend and/or size the proposed
culvert. It is understood that a maximum of 2 design alternatives will be provided under the
scope of this work. The culvert will be sized with in the guidelines,requirements and criteria
adopted by of the City of Fort Worth. The HEC-RAS Models used for this purpose will be
based on the discharges determined in the previous Task.
d. Create a proposed effective model based on the recommendation adopted for the culvert
and proposed street grades for Keller-Hicks Road.
Task 4 - Recommendations and Final Presentation
This Task includes the preparation of a brief summary of the final recommendations and results
of the analysis. The scope of work necessary for this Task is as follows:
a. Attend a maximum of two meetings with the City Staff to discuss the findings and final
recommendations.
b. Prepare a brief letter report detailing the findings of the analysis. The report will also include
a description of the final recommendation for the construction of the culvert.
Task 5 - Prepare and Submit CLOMR
This Task includes the work necessary for the preparation and submittal of an application to
the Federal Emergency Management Agency(FEMA), for a Conditional Letter of Map
Revision(CLOMR).
a. Following the completion of Task 3, prepare and submit an application for the CLOMR
based on the proposed conditions. For the purposes of this Task, the proposed
condition would include the proposed reconstruction of the spillway for the upper pond.
' i�l`1 oordinate with FEMA and the City of Fort Worth as necessary to facilitate the
N
���'L v5e ".l�vt pplication for the CLOMR.

Task 6 - Prepare and Submit LOMR
This Task includes the work necessary for the preparation and submittal of an application to
the Federal Emergency Management Agency(FEMA), for a Letter of Map Revision
(LOMR). It is understood that this work will be completed after the construction of the
project and that the construction of the project will not be significantly different from the
recommended design.
a. Compare the"as-built"culvert cross sections with those utilized in the post-
construction HEC-RAS model to the previous
b. Following the completion of the construction, prepare and submit an application for the
LOMR based on the as built condition.
c. Coordinate with FEMA and the City of Fort Worth as necessary to facilitate the
application for the LOMR.
Task 7 - Wetlands Determination
This Task includes the work necessary to ascertain the extent of the wetlands and/or
jurisdictional waters with in the project site. The work will be limited to the delineation of
jurisdictional waters and/or wetlands and does not include mitigation efforts and/or activity
associated with an individual permit. It is assumed that this work will disturb less than 0.1
ac of jurisdictional waters.
Assumptions, Exceptions and Exclusions
The following is a list of assumptions, exceptions,and exclusions to this proposal:
a. This proposal assumes that existing hydrologic and hydraulic models exist for Big Bear
Creek.
b. This proposal assumes that existing hydraulic models are available in HEC-RAS and will not
require conversion to HEC-RAS.
c. This proposal assumes that an individual permit from the USACE will not be required. The
proposal,as described herein, is limited to the delineation of the jurisdictional waters within
the project site.
