Amendment No. 2
City of Fort Worth Storm Water Utility
Eastern Hills Storm System Improvements
Scope of Work
PROJECT DEFINITION
The objective of the original scope for this project is to design new and/or upgraded
storm water drainage facilities for the Eastern Hills Watershed. Services to be provided
also include some bidding and construction services, environmental permitting,
hydrologic and hydraulic modeling, and right-of-way/easement assistance. The project is
separated in to two phases; Phase 1 consists of a multi-use storm water detention basin
and associated storm drain system improvements located generally in the southern and
eastern part of the watershed, and Phase 2 (previously known as Phase 2 and 3)
consisting of storm drain system improvements throughout the remainder of the
watershed. Phase 1 was designed in 2010-2011 and is being constructed in 2011-2012.
Phase 2 is scheduled to be designed in 2011-2012 and construction will begin in late
2013. At time of this amendment, the 30% design for Phase 2 has been completed and
reviewed by the City, and much of the phase has been taken to the 60% level of design.
This amendment is organized into two parts: (I) Phase 2 design services modifications
due to a realignment of the project and change of the type of facilities being designed;
and (II) As-needed services to support several potential permitting and construction
administration needs that have or may arise as the work progresses. Part I is provided
on a lump sum basis, similar to the original design contract; Part II is provided on a time
and materials basis to reflect the uncertain nature of the work.
BASIC SCOPE OF SERVICES
I. Shadow Creek Box Culvert Realignment & Channel Improvements
Background
During the process of performing the Phase 2 design work, a workshop was held with
City staff to consider several alignment alternatives for the outfall location of a large box
culvert. The preferred alternative entails re-routing the box culvert to an existing
channel located south of Shadow Creek Court; the existing trunk line system currently
outfalls here via a reinforced concrete arch culvert under Weiler Boulevard that has been
shown to be significantly undersized, so re-routing the diversion box culvert to this same
location will require significant improvements to the receiving channel in order to

Printed: 1/16/2013 1:58 PM
Page 1
prevent erosion and flooding of private property. The area in question can be seen in
Attachment A-1.
The reason this alignment was preferred from the design workshop is that it reduces the
construction in Weiler and avoids existing utility relocations, traffic control, and general
public interference ( existing utilities were not available during the planning and 30
percent design phases). The selected alternative also utilizes the existing channel into
the golf course, whereas the studied alignment would be close to an existing golf course
hole and would likely change the play of the hole both during construction and long
term. All things considered, the change of alignment was seen as a cost savings to the
project and worthy of the design change.
This amendment therefore contains the estimated effort required to incorporate these
channel improvements, and it also details substitutions of existing scope items with new
items related to this design change and other changes, described in detail below.
These new and deleted scope items are summarized in Table 1.

A. Proposed Work
1. Shadow Creek box culvert: To accommodate a request by the City to avoid
constructing the box culvert and related new outfall structure on the Meadowbrook
Updated: October 30, 2012
Printed: 1/16/2013 1:58 PM
Page 3
Golf Course as previously planned and scoped, Jacobs will modify the alignment of
the proposed box culvert starting near station 8+30 on Danciger Dr ive (using
stationing shown on the 30% submittal drawings). The alignment upstream of this
location is not expected to change due to this mod ification.
2. Proposed improvements to existing drainage channel: The realignment of the
proposed Shadow Creek box culvert described above wi ll require improvements to
the existing drainage channel that carries storm water from the outlet of the existing
concrete arch pipe at Weiler Boulevard downstream to Meadowbrook Golf Course.
Proposed improvements will include excavation to widen the channel, MagnumStone
modular block retaining walls lining both sides of the channel, energy dissipaters,
and a new concrete headwall at Weiler Bouleva rd.
i. Civil Design: Prepare construction drawings for the proposed improvements
described above. These drawings will show the layout, grading, profiles, cross
sections, appurtenances, and details necessary to construct the channel
improvements as well as energy dissipators downstream of the Weiler culvert
outlets. Data and engineering calculations from sub-tasks I.A.2.ii-vi will be
utilized in preparation of these drawings. This design will include the location,
alignment, limits, and top-of-wall elevations for the proposed MagnumStone
modular block retaining walls that will line both sides of the outfall channel.
ii. Structural Design: Jacobs will provide design of energy dissipaters and an
approximately 35' long retaining wall with pipe penetrations (headwall), including
all necessary calculations, drawings, details, and quality reviews. Jacobs will
provide construction administration (CA) review of retaining wall submittals
(concrete/rebar) by the City's contractor. The proposed MagnumStone modular
block retaining walls that will line the channel downstream of the headwall will
be a "designated design," meaning that structural design calculations will be
provided by the contractor and must be signed and sealed by a registered
professional engineer. Jacobs will provide CA review of this modular block wall
and foundation design submittal. (See Phase II CA services)
iii. Survey and Subsurface Utility Engineering (SUE): See attached scope from ANA,
included and made a part of this contract as Attachment A-2. Preparation of any
temporary and permanent easements will be performed per the original contract
scope.
iv. Geotechnical Investigations: See attached scope from Mas-Tek, included and
made a part of this contract as Attachment A-3.
v. Environmental Permitting: Jacobs will expand the scope of the USACE
environmental permit investigation and preparation to include modifications to
the existing channel. The environmental services to be performed for the stream
bank modification associated with Phase II will include the performance of a
preliminary jurisdictional delineation and corresponding report identifying the
Section 404 jurisdictional li mits of the stream and other associated areas subject
to Section 404 that may be associated with the stream. In addition, information
addressing this portion of the project will be incorporated into a U.S . Army Corps
of Engineers' (USACE) Nati onwide Permit (NWP) 43 (Stormwater Management
Facilities) preconstruction notification permit application for transmittal to the
USACE Fort Worth District in requesting authorization fo r the project under th is
Updated: October 30, 2012
Printed: 1/16/2013 1:58 PM
Page 4
NWP. Jacobs will also tag and identify all trees within the existing drainage
easement plus a 15-foot buffer. ANA will provide surveyed locations for trees
larger than 6-inches (standard caliper measurement) as described in the scope
included and made a part of this contract as Attachment A-2.
vi. Hydraulic Modeling (HEC-RAS and InfoWorks SD): Jacobs will perform
preliminary sizing of the channel using HEC-RAS, using flows taken from the
InfoWorks SD model prepared under Amendment #1, and this HEC-RAS model
will be used to establish proposed grading and other design elements for the
30% submittal. After approval of the 30% design, any changes required for the
60% submittal will be modeled using the HEC-RAS model; subsequently, the
proposed channel grading will then be added to the InfoWorks SD model and the
results of both models compared for reasonableness; this comparison is
necessary since the InfoWorks SD channel modeling capabilities are not as well-
understood or widely accepted as HEC-RAS. It is not expected that significant
changes will be required going from 60% to final drawings (90% and 100%), but
any changes that are made to the design will be incorporated into the models for
final submittal of same. If significant changes are required, additional scope and
budget may be necessary.
3. Proposed pipe from Jacqueline to Yolanda: The original concept plan for this
improvement alignment, as determined during the watershed study phase of the
project, was to design and install a new relief pipe running generally parallel to the
existing natural drainage channel, with the constraint of keeping the pipe within the
existing easement (most of the channel does not lie within the easement). After
obtaining survey information and making another site visit with City staff, it was
determined that this proposed alignment along the existing easement would require
deep trenching in some locations due to a steep hillslope that exists in some of the
backyards. This trenching would be very disruptive to established backyards, and
could require the City to remove and replace landscaping, vegetation, fences, decks
and footbridges that span the drainage channel, a gazebo, utility poles, outbuildings,
and other similar backyard items. Based on preliminary model results simulating the
new proposed improvements described in scope item numbers 4 and 5 below, it
appears that storm water flooding can be reduced in this backyard channel without
installation of this pipe. The previous scope envisioned improved inlets at the sump
on Jacqueline near the upstream end of this channel; this change would eliminate
those new inlets as well.
4. Inlets near Jacqueline/ Yolanda intersection: A pair of proposed inlets on either side
of a valley gutter on Jacqueline, near Weiler, are currently planned to be piped east
(down Jacqueline) to the proposed pipe (parallel to the existing channel, eliminated
in item #3 above) that runs behind the houses along Yolanda. In order to provide
relief to the existing system at the sump in Jacqueline and to the existing natural
drainage channel, it was decided to instead take the flow from these inlets
(approximately 30 cfs) and carry it west to Weiler, extending the proposed system
farther to the north along Weiler to connect. Survey and SUE was not obtained for
part of this area in the original scope, and Jacobs does not propose to collect it at
this time. Jacobs proposes to digitize surface features to fill in the gap between the
existing survey for Weiler and Jacqueline; the only utility potentially impacted
Updated: October 30, 2012
Printed: 1/16/2013 1:58 PM
Page 5
appears to be a 12-inch water line, and missing information for this can be filled in
from plans.
5. Upgrade Yolanda crossing: The existing 2-36" reinforced concrete pipe structure
under Yolanda (between Jacqueline and Danciger) appears to be undersized based
on preliminary model results; improvements here were not part of the concept plan
developed during the watershed study phase, but current modeling and field
assessment suggests a new structure may be required. This scope change would
upgrade this crossing to a larger box culvert that would reduce overtopping potential
and improve capacity in the natural drainage channel upstream.
6. Parks conversion permit: The existing scope for parks conversion permit is moved
from the lump sum portion of the budget to the as-needed, time and materials
section (Part II) since the need for this permit is uncertain at this time and will be
determined as the design progresses.
7. SWPPP change to iSWM Checklist: This provides for the change from to the city
standard now being used, the iSWM Site Plan Checklist, instead of the consultant-
supplied SWPPP process being used at the beginning of the project.
B. Deliverables
1. Conceptual drawings: 30% design package submittal showing the revised
alignments, dimensions, and other key design elements for the items revised by this
scope (1-5), including how they tie into the rest of the project.
2. 30% Review meeting: Jacobs will prepare for and attend one (1) project review
meeting with City staff to present, discuss, and gather feedback from the 30%
submittal for the items revised by this scope (1-5).
3. 60% Drawings: Jacobs will incorporate the 30% design review comments for items
revised by this scope (1-5) into the 60% design package and submit to the City,
making one submittal for all of Phase 2. The Phase 2 60% design review meeting is
covered by the original scope.
4. Final (90% and 100%) Drawings: Jacobs will incorporate the 60% design review
comments for items revised by this scope (1-5) into the 90% design package and
submit to the City, making one submittal for all of Phase 2. The Phase 2 90% design
review meeting is covered by the original scope.
5. Revised geotechnical report: Jacobs will provide a revised geotechnical report that
includes previous bores, analysis, and recommendations, as well as information for
new bores acquired for the new alignment and channel improvements. This report
will include global stability analysis for the proposed retaining walls lining the
channel. These walls will be a designated design, and this analysis will be provided
to the contractor for that purpose. Jacobs structural engineers will review and
approve the submitted design as appropriate.
C. Assumptions
1. Hydrology (SCS method) developed during the watershed planning study and refined
during the original scope and previous amendments to this contract will be used as a
Updated: October 30, 2012
Printed: 1/16/2013 1:58 PM
Page 6
starting point for this modeling effort and refined as required by the design to
accommodate new proposed inlets.
2. The new proposed channel will be designed to carry the 100-year storm.
3. This scope assumes that no street grades will change due to any proposed
improvements.
4. Should the USACE require compensatory mitigation for Section 404 waters of the
U.S. impacts resulting from the project, then it is assumed the City will purchase
mitigation banking credits from an USACE-approved mitigation bank.
5. Geotechnical work will include 6 borings of varying depth in the vicinity of the Weiler
headwall and downstream channel. An allowance for rock coring is included if
required (see additional services category below).
6. Tree trimming will be performed by the geotechnical subconsultant's personnel or
their contractor, for work in and around backyards and the existing channel. The
subcontractor cost provided includes one (1) day of tree trimming and removal of
trimmings from sites. Tree trimming will be performed under direction of the City
arborist.
7. Right of entry will be acquired by Jacobs and/or its subcontractors for access
through the golf course and two private properties for geotechnical borings, surveys,
and tree surveys.
8. The fee for geotechnical engineering services includes costs for the drill crew to lay
plywood sheeting progressively beneath drill equipment along access routes across
the golf course and private properties to minimize rutting as the drill equipment
travels across the golf course and two private properties for distances of 200 feet to
350 feet; costs are provided based on two days of drilling activity. Ruts created by
drilling operations will be repaired by a landscaper directed by the geotechnical
engineer, with costs reimbursed by the City. An allowance of up to $5,000 is
provided for rut repair work as additional services (see additional services category
below).
9. Urban Forestry Permit plan review fee of $250 will not be paid by Jacobs.
10. Additional iterations of forestry permit will be considered additional services.
D. Exclusions
No fees have been provided for the items listed below. If they are subsequently needed
or desired by the City additional scope and compensation will be required.
1. Hydrologic and hydraulic modeling will be performed only on existing and proposed
storm drain infrastructure within the Eastern Hills watershed as described herein, in
the original scope, and in previous amendments . Should additional modeling be
required using additional storms, on other waterways or within other watersheds
that work will be accomplished as Additional Services, after approval by the City.
2. This scope does not include any review fees associated with submittals to FEMA such
as a Letter of Map Revision (LOMR); at present, the review fee for a LOMR of this
nature (map change based on bridge, culvert, channel, or combination thereof) is
Updated: October 30, 2012
Printed: 1/16/20131:58 PM
Page 7
$5,300, and is subject to a yearly review and revision cycle. It is not expected that a
Conditional Letter of Map Revision (CLOMR) will be required for this project.
3 . Jacobs will not design any modifications or improvements to private structures such
as sheds that may be located within any existing or proposed easements. If such
structures are affected by any proposed improvements Jacobs will inform the City
and provide information about the nature of the improvements at that location to
the City's rea l properties group.
4. Any other additional work not specifically included in the above scope of services will
be accomplished as Additional Services, after approval by the City.
5. For the tree mitigation area, it is assumed that the contractor will be asked to submit
an irrigation design including water and power supply as required for the trees and
plants, and that design for these items will not be included in the bid documents .
II. Additional Services
Fees are provided for the items listed below in case they are determined to be
necessary. Compensation will be provided on a time-and-materials basis according to
the rates, personnel, and reimbursable costs detailed for each "Additional Serv ices" item
as detailed in Attachment B.
1. Floodplain Development Permit: The proposed channel improvements lie w ithin
the regulatory (Zone A) FEMA floodplain of Shadow Creek, a tributary to
Woodhaven Creek, as shown on panel 48439C0215K of the Tarrant County,
Texas Flood Insurance Study, effective 9/25/2009. Jacobs will prepare and
submit a floodplain development permit to the City of Fort Worth documenting
the effects of the proposed channel improvements on the floodplain from the
downstream face of Weiler to the tie-in with the Zone AE floodplain of Shadow
Creek. No modeling or mapping on Shadow Creek is included or anticipated.
Modeling prepared under item vi, Hydraulic Modeling, will be utilized to prepare
proposed floodplain mapping exhibits and a short technical memo for review and
approval by City floodplain management staff. It is expected that a letter of map
revision (LOMR) will ultimately be required for this area. Since a LOMR cannot be
prepared and approved until after all construction is complete, and construction
is not currently scheduled to begin until December 2013, the effort for
preparation and submittal of the LOMR is included in this amendment as an
additional service (see below).
2. Urban Forestry Permit: If needed, Jacobs will prepare and coordinate an
Application for an Urban Forestry Permit (Application) in accordance with the City
of Fort Worth Tree Ordinance requirements inclusive of the preparation of an
Urban Forestry Plan Check List (Check List). Two (2) paper copies each of the
Check List and Application will be provided to the Client.
Data Collection and Evaluation: Collect various i nformation to be used for the
preparation of the Check List and Application. This will include conducting a tree
survey of the project area which is comprised of approximately 1. 7 acres. The
tree survey will be performed in accordance with the City of Fort Worth Tree
Ordinance requirements. It is estimated that approximately 40 -50 trees will
Updated: October 30 , 2012
Printed: 111612013 1:58 PM
Page 8
need to be evaluated and surveyed within the project area. Following the data
collection effort, the information will be evaluated and organized for use in
preparing the Check List and Application.
Urban Forestry Plan Check List: In coordination with the Project Manager and
Project Landscape Architect, prepare the draft Urban Forestry Plan Check List and
provide the Client with one (1) hard copy for review and comment. Subsequent to
receipt of review comments from the Client, prepare and transmit the final Check
List for evaluation and processing. Perform on-going coordination with the City of
Fort Worth Arborist during the review/approval process.
Application for Urban Forestry Permit: In coordination with the Project Manager and
Project Landscape Architect, prepare the Urban Forestry Permit Application and
provide the Client with one (1) hard copy for review and comment. Subsequent to
receipt of review comments from the Client, prepare and transmit the final
Application for evaluation and processing. The Application will be submitted
simultaneously with the Check List. Associated items to include with the Application
include two (2) full size Phase I (Existing Conditions Plan) and Phase II (Site
Alterations/Planting Plan) Plan copies (tri-folded with name of project on copy face;
one (1) 8.5 x 11-inch mini map of image area of plan; digital copies (CD or DVD) of
the Phase I and Phase II Plans; one (1) full size plat copy folded to City of Fort
Worth standards. Perform on-going coordination with the City of Fort Worth Arborist
during the review/approval process.
3. Parks Conversion Permit: If needed, the parks conversion permit work as
described in the original scope of work will be provided.
4. Tree Mitigation Planting Plan: If needed, Jacobs will prepare a tree mitigation
plan in association with the urban forestry permit and incorporate the plan into
the design plans. The mitigation area is assumed to be available within the limits
of the area shown on Attachment A-1.
5. Rock Coring: An allowance for rock coring by the geotechnical engineering
subconsultant is included, should subsurface conditions require. Costs for rock
coring are $60.00/foot if performed using portable equipment and/or $35.00/foot
if performed using a 4-wheel drive all-terrain vehicle; the use of a particular
piece of equipment is at the geotechnical engineer's discretion based on his
professional judgment.
6. Tree Trimming: An allowance of $2,750 is included for tree trimming on private
property, within the existing drainage easement, or on Meadowbrook Golf Course
as may be required to obtain the geotechnical bores. Tree trimming will be
performed by the geotechnical engineering subconsultant's personnel or their
contractor, for work in and around backyards and the existing channel. The
allowance cost provided includes one (1) day of tree trimming and removal of
trimmings from sites. Tree trimming will be performed under direction of the City
arborist.
7. Rut Repair: While the geotechnical engineering subconsultant is taking steps to
reduce the risk of tire and rut damage to private property or Meadowbrook Golf
Course, the possibility for such damage still exists. Ruts created by drilling
operations will be repaired by a landscaper directed by the geotechnical

Page 9
engineer, with costs reimbursed by the City. An allowance of up to $5,500 is
provided for rut repair work as additional services .
8. Letter of Map Revision (LOMR): As described in section II.1 of this document, the
channel modifications are located in a regulatory FEMA floodplain (Zone A,
approximate study area), and as such will ultimately require a Letter of Map
Revision (LOMR) submittal to FEMA to revise the floodplain limits in this area.
After construction of these channel improvements is complete, Jacobs wil l obtain
as-built survey data of the improvements, provided by the contractor and/or City
of Fort Worth, and use it to revise the previously-prepared HEC-RAS model to
reflect the actual post-project conditions of the channel and floodplain. The limits
of this model and floodplain revision are as described in section IL 1.
Since FEMA does not presently accept the lnfoWorks software packages for map
revisions, Jacobs will update existing models that are acceptable for FEMA
submittals for the hydrology and existing hydraulics portions of the submittal. For
hydrology, Jacobs will revise an existing HEC-HMS model, which was originally
prepared during the watershed study phase of this project, to accurately reflect
watershed conditions at the time the LOMR is prepared . For pre-project
conditions hydraulics, Jacobs will update a HEC-RAS model of the existing
channel configuration, also prepared during the watershed study phase of this
project, extending it downstream to the limits described above and extending
cross sections laterally as necessary to accurately model and map the floodplain.
9. Jacobs will prepare a LOMR submittal package for the limits of the stream as
described above, including all necessary information to reclassify the floodplain
as Zone AE ( detail study), including 100-year and 500-year floodplains, base
flood elevations (BFEs), and summary of discharge tables. This scope assumes
that a floodway will not be developed for this stream. The submittal package also
includes notification letters to affected property owners and coordination with
FEMA reviewers as necessary during the approval process. Phase 1 Expanded
Construction Administration (CA) Services
The scope/fee provided for Phase 1 services during construction included 8 site visits. As
of the end of May 2012, 19 visits had been provided As of July 2012, the contractor has
installed topsoil and landscaping that does not appear to meet the standards of material
quality or installation as shown in the contract documents for this project. Beginning in
June 2012, Jacobs engineers and landscape architects undertook an effort to provide
expanded construction services to help identify and correct deficiencies with the installed
landscaping, topsoil, misaligned maintenance access road, and other items as needed.
Assistance with earthwork quantities was also provided to help with contractor
questions. These items depleted the existing CA services budget.
A. Proposed Work
1. Additional coordination, construction observation, submittal review, and site visits
will be provided to assist the City in guiding the contractor as he completes the
construction of the basin. This work will be provided on a time and materials basis,
not to exceed$25,000.
Updated: October 30, 2012

B. Deliverables
Jacobs will collect and provide documentation of the additional coordination,
construction observation, submittal review, and site visits. Documentation may include
construction photographs, memoranda, or other forms of documentation to help assure
that the contractor provides the materials and workmanship required for the landscape
elements of the contract documents.
C. Assumptions
1. Services to be provided on an as-needed basis as requested by City staff or
consultant PM. Hourly rates will be based upon the contracted rate schedule, Rates
are subject to review and annual adjustments .
10. Phase 2 Bidding and Construction Administration (CA) Services
The original contract did not provide for these services, so they are being included in
this amendment to assist with the Phase 2 construction process.
A. Proposed Work
Bid Phase: Provide same services as that for Phase 1. Refer to original contract, Task 5.
Construction Phase: The following list presents an estimate of the level of effort required
to support Phase 2 construction .
• Site Visits (2 per month for 12 months, 8 hr/visit) -192 hr
• Pond inspections -60 hr
• Channel inspections -40 hr
• Respond to city staff /council questions -50 hr
• Respond to contractor questions -40 hr
• Submittal review for 20 submittals -40 hr
• RFI responses -40 hr
• Public meeting support -28 hr
• Record drawings -60 hr
The total effort for Phase 2 construction services is therefore estimated at 550 hours.
B. Deliverables
Jacobs will collect and provide documentation of the additional coordination,
construction observation, submittal review, and site visits. Documentation may include

RECOMMENDATION:
It is recommended that the City Council authorize execution of Amendment No. 2 to City Secretary
Contract No. 40850, an Engineering Services Agreement with Jacobs Engineering Group, Inc., in the
amount of $265,500.00 for the design of the Eastern Hills Drainage Improvements Project - Phase 2,
thereby revising the total contract cost to $917,167.00.
DISCUSSION:
The amendment recommended by this Mayor and Council Communication will provide the following:
design for a revised outfall location with associated survey and subsurface utility engineering, and
permit/bidding construction phase services. A revised outfall location is needed to limit impacts to the
Meadowbrook Municipal Golf Course.
The Eastern Hills Drainage Project is divided into two Phases. Phase 1 provided a dual-use facility

for the northern portion of the Eastern Hills neighborhood.
On June 22, 2010, (M&C C-24294) the City Council authorized an Agreement with Jacobs
Engineering Group, Inc., (Jacobs), to design this project. Jacobs proposes to perform the additional
design services for a lump sum fee in the amount of $87,850.00 and to provide the remaining
services on a time and materials basis, as needed, not to exceed $177,650.00. The total proposed
fee in the amount of $265,500.00. Staff considers the fee to be fair and reasonable for the scope of
services proposed.
Funding for this project is being provided from revenue bonds in the Stormwater Capital Projects
Bond Fund.
Jacobs Engineering Group, Inc., is in compliance with the City's M/WBE Ordinance by committing to
an additional 14 percent M/WBE participation on this Change Order No. 2. The City's goal on this
amendment, change order or extra work is 14 percent.
This project is located in COUNCL DISTRICT 4, Mapsco 79C.
FISCAL INFORMATION/CERTIFICATION:

budget, as appropriated, of the Stormwater Capital Projects Bond Fund.
