PROJECT DESCRIPTION
This Supplemental Contract consists of preparation of final PS&E plans for the project. The
proposed project includes an approximately 0.5 mile new location 4-lane roadway with raised
median between Wyoming Springs Drive and Pena Cove. A single bridge is proposed, spanning
both Hairy Man Rd and Brushy Creek. The project will also include the reconstruction of
approximately 200 feet of Creek Bend Circle.
TASK 1: SURVEYING
Supplemental Suiroey
1. Recover, verify, or establish primary control monument$ at strategic locations at the east
and west termini of the proposed project corridor as inter-visible pairs with no greater
than 1500 feet between each monument.
2. Establish a vertical control system for the project. A benchmark system will established
at approximately 1000' intervals along the project route.
3. Previous ground survey has been performed for approximately 170 feet along Creek
Bend Circle and along existing Creek Bend Boulevard from Hairy Man Road to Pena
Cove. Supplemental topographic and planimetric mapping of the remaining proposed
corridor will be performed. This will include mapping of existing curbs, pavements,
visible and exposed utilities, structures, drainage facilities and other improvements that
may affect design criteria.
4. Tree surveys of the corridor consisting of mapping and tagging 12 inch and larger
hardwoods.
S. Borehole location surveys will be provided along the corridor at 15 locations.
6. Centerline and ROW staking will be done on one hundred foot stations along the corridor
for environmental and geotechnical investigation purposes.
ROW Acquisition Survey
1. Provide Boundary surveying services for determination of the Creek Bend Extension
ROW from Creek Bend Circle to Wyoming Springs Blvd. in Round Rock, TX. y
2. The Surveyor does not anticipate the need for ROE to private properties along the project
route. Should the need become necessary for task completion, Inland will contact the
landowner directly or. through other means to attempt to gain access to the property.
Records on landowner contact will be forwarded to City Project Managers. <
3. Generate, recover, and/or verify existing horizontal and vertical project primary control
throughout the site (if any), and reconcile the control to the City of Round Rock GPS
Monument system. For the purposes of this survey it is understood that vertical control
measurements are not a requirement for task completion.
4. Establish or densify additional secondary control as needed for the project to collect data
and boundary evidence along the length of the project.
Page 1 of 11 s
5. Perforin sufficient research of property records from various sources to analyze and
develop an exhibit of the record ROW and property configurations for the affected tracts.
Inland will perform sufficient field work to recover property corners and highway
monuments to aid in the analysis and reconstruction of the tracts where parcels will be
acquired, estimated at 7 parcels and 7 easements (total 14) for this proposal.
ASSUMPTIONS
The Surveyor shall notify the client prior to performing the work if: '
a. Sufficient right-of-way nionunientation cannot be found to re-establish the
existing alignments and associated right-of-way lines along the project corridor.
This proposal does not provide for field surveying of the adjoining property
sidelines. The sidelines will be depicted based on record data only.
b. Traffic Control cannot be managed by the Surveyor's persormel.
c. The work is delayed due to weather or other circumstances beyond the Surveyor's
direct control.
d. Coordination with City personnel or landowners that limits the access to their
installations or availability of records for the survey.
TASK 2: ROUTE STUDY
TASK 3: ENVIRONMENTAL STUDIES
1. With the exception of resampling federally-listed karst invertebrates (as requested by
USFWS, previous data collected for threatened or endangered species habitat
assessments would be sufficient for updating various project documents and reports only
within the previously-evaluated ROW.
2. All areas not previously evaluated for federally-listed species will require a habitat
assessment, including a Phase 1 Karst Survey. New proposed ROW limits include areas
not previously-evaluated and include an extension to the north.along Creek Bend Blvd
4
and Creek Bend Circle, and the Creek Bend Joint Venture property on the east side of
Creek Bend (just north of Harry Man Road) for a proposed water quality pond.
3. Due to potential impacts to Creek Bend Cave, it would necessary to coordinate potential
participation into the Regional Habitat Conservation Plan (RHCP) with USFWS. If
participation in the RHCP is not an option, then USFWS is likely to request a resample of a'
karst invertebrates in Creek Bend Cave as part of presence/absence sampling protocols
for federally-listed species. Atkins would assist City of Round Rock with potential
participation in the RHCP. Additional karst surveys are not included within this scope of
work at this time as it is dependent upon USFWS coordination outcomes.
4. The Karst Survey Report and Species Habitat Report would be updated to reflect any
potential changes to expected project impacts as necessary.

discharge thresholds and no new work associated with Section 404-regulated waters are
anticipated (including no revisions to the Waters of US Repoli, and no field surveys).
7. Complete analysis of artifacts previously collected during Phase I archaeological
resources investigations and prepare materials for curation or return to property owner.
8. Update archaeological resources report to reflect changes in the project by the elimination
of Hairy Man Road Connection and submit report to Texas Historical Commission. A
brief additional field visit will be necessary to evaluate new proposed ROW limits
include areas not previously-evaluated and integrate new data into the final report.
9. Following acceptance of archaeological report by Texas Historical Commission, deliver
project collections to the Texas Archeological Research Laboratory or return to property
owner

Bridge Modeling and Impacts Analysis
1. From the 30% design, it appears that there will be impacts to the 100-year water surface
elevation upstream of the proposed bridge due to the water quality pond, bridge piers and }
abutments. Additionally, Hairy Man Road Bridge is to remain in place and is also a
source or hydraulic energy loss that tends to increase the upstream water surface
elevation. The majority of the impacts appear to be associated with the water quality t
pond which is currently sited under the bridge, and represents a fairly significant
obstruction to flow. Atkins will develop a plan to minimize impacts due to the proposed
bridge, and coordinate with City staff and the floodplain administrator to develop an
overall strategy to minimize any impacts to the 100-year floodplain. Solutions developed
will consider the high aesthetic quality of Brush Creek and 404 permitting issues.
Existing and proposed 100-year floodplain boundaries will be mapped so that any
impacts may be seen in relation to surroundings.
2. The Brushy Creek Watershed is currently being restudied-to update flooding conditions
therein. Atkins has been in contact with the Upper Brushy Creek Water Control and A
Irrigation District (UBCWCID) staff and it is understood that preliminary updated
models might be available as early as July of 2012. Atkins will coordinate with the
UBCWCID and City staff to obtain the best available hydrologic and hydraulic modeling
information for use in the hydraulics impacts analysis. If the UBCWCI models cannot be
s
Page 7 of 11
i
f
I
obtained, then other best available information will be used to evaluate the proposed
bridge impacts.
3. Based on the 100% design plans, and the best available information, Atkins will develop
a Conditional Letter of Map Revision(CLOMR)to document the changes to the 100-year
floodplain as a result of the proposed bridge and other related modifications. Atkins will
develop all necessary information including hydrologic and hydraulic modeling,
floodplain figures, and MT-2 Application forms, and a report summarizing analyses and
results. Our effort will also include responding to comments from both the applicable
floodplain administrator and FEMA reviewer to obtain CLOMR approval. After the
project is constructed, a Letter of Map Revision will be developed and submitted to
FEMA to document the final grades and structural details of the bridge and other related
modifications that affect the floodplain determination. As with the CLOMR, die LOMR
work effort will produce all relevant hydrologic and hydraulic modeling, floodplain
mapping, the MT-2 Form, and a summary report. Please note that the CLOMR
application requires compliance with the Endangered Species Act, and may require a
letter from the United States Fish and Wildlife.
4. A potential scour assessment will be performed for the proposed bridge design. This
assessment will consider the gradation of the channel bed material, boring data, channel
slope, channel shear and incipient motion of the average bed material..If this assessment
indicates that there is a potential for scour, then a more detailed scour analysis will be
performed using either HEC-18 guidelines or the Texas Secondary Evaluation and
Analysis for Scour (TSEAS, 1993). If it is determined from this potential scour
assessment that a detailed scour analysis is required then additional services may be
requested.
5. A technical memorandum documenting hydrologic and hydraulic modeling assumptions
for the bridge impacts, onsite drainage and water quality considerations will be provided.
Onsite Drainaee
6. Onsite drainage plans including storm drains, inlets, outfalls and other associated
drainage considerations will be adjusted as required to comply with the City's review
comments of the 30%design plans.
7. Provided that inlet filtration is used in lieu of a water quality pond, onsite drainage plans
will be amended to include itildt filtration locations, sizes, and other design details.
Water Quality Considerations
8. As mentioned above, based on the 30%design effort, it appears that there will be impacts
to the 100-year water surface elevation, in particular if the water quality pond is sited
tinder the bridge. Therefore, it is recommended that inlet filtration devices be used to
satisfy TCEQ water quality standards for construction over the Edwards Aquifer recharge
zone. Atkins will coordinate with City staff to devise a water quality strategy using either
inlet filtration or a water quality pond.
9. As this project site is located over the Edwards Aquifer recharge zone, TCEQ requires a
WPAP be submitted to prove that the required pollutant removal rates are achieved for
proposed conditions. Atkins will meet and coordinate with both City and TCEQ staff
during the 60% design effort in order to obtain preliminary concurrence with the
Page 8 of l l
I
proposed water quality strategy. Atkins will develop and submit the WPAP to TCEQ,
and respond to TCEQ comments as required to assist in obtaining TCEQ approval for the
construction of this project.
10. Atkins will provide Storm Water Pollution Prevention Plans(SWPPP)to minimize
sediment discharge from the project area during construction in accordance with best
management practices,
11. Atkins will provide water quality construction plans and details sufficient to construct the
water quality elements for this project as agreed upon by City Staff and approved by
TCEQ.
TASK 11: 95% PLANS
All Disciplines
1. Address comments from the City of Round Rock 60%review.
2. Continue development and detailing of sheets.
3. Prepare construction cost estimate, construction time estimate,specifications, and general
notes.

2. Prepare construction cost and construction time estimates,
3. Prepare specifications and general notes.
4. Prepare bid-packages, attend bid opening and process bids.
NOT INCLUDED WITHIIN THIS SCOPE {
The following items are not included with this scope because the level of effort to complete these
tasks is very dependent on the final route selected. These items, if necessary, would be added to
die scope through a supplemental agreement.
1. A detailed scour analysis will not be performed; instead a potential scour analysis
considering channel bed material gradation, boring data, channel slope,channel shear and
incipient motion of the average bed material will be performed.
2. Hydrologic and/or hydraulic modeling of the upstream watershed.
3. It is assumed that a water quality solution will be chosen that does not require any
structural design. If water quality ponds are included, additional scope will need to be
added for the structural design portion of the ponds.
4. Traffic signal design is not included in this effort.
{
Page 9 of 11
i
}
5. Additional scope for presence/absence surveys for federally-listed karst invertebrates are
not included at this time as it is dependent upon potential participation in the RHCP and
coordination with USFWS.
6. Additional habitat evaluations for federally-listed species would be necessary on ROW
segments not previously-evaluated. The habitat evaluation would include a Phase 1 Karst
Survey. If karst features are encountered, additional karst surveys (i.e., Phase 2 or Phase
3)would be covered under a separate scope of work and cost estimate, if necessary.
7. The project team currently assumes that Brushy Creek would be fully spanned; if bridge
designs change and result in discharge of fill material below the ordinary high water mark
(OHWM) of Brushy Creek exceeding 0.10 acre, then a Pre-Construction Notification to
the US Army Corp of Engineers (USACE) would be necessary, Please note that the PCN
process would result in USACE coordination,report updates,permit acquisition,etc.,and
is not included within this scope. A scope for the USACE permit acquisition process
would be provided if changes to design exceed a discharge of 0.10 acre within Brushy f
Creek's OHWM. Under NWP 14, discharges of fill within regulated waters over 0.10
acre would require PCN to the USACE, and NWP 14 allows for up to 0.50 acre of
discharge.
8. The project team assumes the project will be constructed using local funding sources and
will not require any federal permitting. As a result, no further documentation or
coordination regarding non-archeological historic-age resources is included in the current
scope.
9. Water System Hydraulics, System Capacity, and Diameter Selection --The CoRR Staff
has evaluated and addressed these components of the project.
10. Water System Engineering Report - An engineering report is not anticipated for the water
transmission line project.
DELIVERABLES
ROW Mapping
1. Final deliverables will be numbered individual parcel plats with metes and bounds
descriptions. Additionally, a ROW plan set will be generated with parcel numbers of the
entire project route.
2. The Surveyor shall place or replace monuments marked as "CORR ROW" at points

PROJECT DESCRIPTION
This Supplemental Contract consists of preparation of final PS&E plans for the project. The
proposed project includes an approximately 0.5 mile new location 4-lane roadway with raised
median between Wyoming Springs Drive and Pena Cave. A single bridge is proposed, spanning
both Hairy Man Rd and Brushy Creek. The project will also include the reconstruction of
approximately 200 feet of Creek Bend Circle.
TASK 1• {
. SURVEYING ,
Supplemental Survey
1. Recover, verify, or establish primary control monuments at strategic locations at the east
and west termini of the proposed project corridor as inter-visible pairs with nio greater
than 1500 feet between each monument.
2. Establish a vertical control system for the project. A benchmark system will established
at approximately 1000' intervals along the project route.
3. Previous ground survey has been performed for approximately 170 feet along Creek
Bend Circle and along existing Creek Bend Boulevard from Dairy Man Road to Pena
Cove. Supplemental topographic and planimetric mapping of the remaining proposed
corridor will be performed. This will include mapping of existing curbs, pavements,
visible and exposed utilities, structures, drainage facilities and other improvements that
may affect design criteria.
y
4. Tree surveys of the corridor consisting of mapping and tagging 12 inch and larger
hardwoods.
S. Borehole location surveys will be provided along the corridor at 15 locations.
b. Centerline and ROW staking will be done on one hundred foot stations along the corridor
for environmental and geotechnical investigation purposes.
ROW Acquisition Survey
r
1. Provide Boundary surveying services for determination of the Creek Bend Extension t
ROW from Creek Bend Circle to Wyoming Springs Blvd. in Round Rock, TX.
2. The Surveyor does not anticipate the need for ROE to private properties along the project
route. Should the need become necessary for task completion, Inland will contact the £
landowner directly or through other means to attempt to gain access to the property.
Records on landowner contact will be forwarded to City Project Managers.
3. Generate, recover, and/or verify existing horizontal and vertical project primary control
throughout the site (if any), and reconcile the control to the City of Round Rock GPS
Monument system. For the purposes of this survey it is understood that vertical control
measurements are not a requirement for task completion.
4. Establish or densify additional secondary control as needed for the project to collect data
and boundary evidence along the length of the project.
i
11a8c 1 or 1 I
5. Perforin sufficient research of property records from various sources to analyze and
develop an exhibit of the record ROW and property configurations for the affected tracts.
Inland will perform sufficient field work to recover property corners and highway
monuments to aid in the analysis and reconstruction of the tracts where parcels will be
acquired, estimated at 7 parcels and 7 casements (total 14) for this proposal.
ASSUMPTIONS
The Surveyor shall notify the client prior to performing the work if:
a. Sufficient right-of-way nionunientatron cannot be found to re-establish the
existing alignments and associated right-of-way lines along the project corridor.
This proposal does not provide for field surveying of the adjoining property
sidelines. The sidelines will be depicted based on record data only.
b. Traffic Control cannot be managed by the Surveyor's personnel.
c. The work is delayed due to weather or other circumstances beyond the Surveyor's
direct control
d. Coordination with City personnel or landowners that limits the access to their
installations or availability of records for the survey. a
TASK 2: ROUTE STUDY
i
TASK 3: ENVIRONMENTAL STUDIES ry
1. With the exception of resampling federally-listed karst invertebrates (as requested by '
USFWS, previous data collected for threatened or endangered species habitat
assessments would be sufficient for updating various project documents and reports only x
within the previously-evaluated ROW.
2. All areas not previously evaluated for federally-listed species will require a habitat s
assessment, including a Phase 1 Karst Survey. New proposed ROW limits include areas
not previously-evaluated and include an extension to the north.along Creek Bend Blvd k
and Creek Bend Circle, and the Creek Bend Joint Venture property on the east side of
Creek Bend (just north of Harry Man Road) for a proposed water quality pond.
3. Due to potential impacts to Creek Bend Cave, it would necessary to coordinate potential
participation into the Regional Habitat Conservation Plan (RHCP) with USFWS. If
participation in the RHCP is not an option, then USFWS is likely to request a resample of
karst invertebrates in Creek Bend Cave as part of presence/absence sampling protocols
for federally-listed species. Atkins would assist City of Round Rock with potential
participation in the RHCP. Additional karst surveys are not included within this scope of
work at this time as it is dependent upon USFWS coordination outcomes.
4. The Karst Survey Report and Species Habitat Report would be updated to reflect any I
Potential changes to expected project impacts as necessary.

5. An addendum to the Geologic Assessment prepared for the Texas Commission on
Environmental Quality (TCEQ) Water Pollution Abatement Plan (WPAP) will be
prepared for the additional project areas not evaluated in the previous studies.
d. It is assumed that bridge design would not exceed Nationwide Permit (NWP) 14
discharge thresholds and no new work associated with Section 404-regulated waters are
anticipated (including no revisions to the Waters of US Report, and no field surveys).
7. Complete analysis of artifacts previously collected during Phase I archaeological
resources investigations and prepare materials for curation or return to property owner.
8. Update archaeological resources report to reflect changes in the project by the elimination
of Hairy Man Road Connection and submit report to Texas Historical Conunission. A
brief additional field visit will be necessary to evaluate new proposed ROW limits
include areas not previously-evaluated and integrate new data into the final report,

Drainag
Bridge Modeli pig and Impacts Analysis t
i
I. From the 30% design, it appears that there will be impacts to the 100-year water surface
elevation upstream of the proposed bridge due to the water quality pond, bridge piers and
abutments. Additionally, Hairy Man Road Bridge is to remain in place and is also a
source or hydraulic energy loss that tends to increase the upstream water surface
elevation. The majority of the impacts appear to be associated with the water quality
pond which is currently sited wider the bridge, and represents a fairly significant
obstruction to flow. Atkins will develop a plan to minimize impacts due to the proposed
bridge, and coordinate with City staff and the floodplain administrator to develop an
overall strategy to minimize any impacts to the 100-year floodplain. Solutions developed
will consider the high aesthetic quality of Brush Creek and 404 permitting issues.
Existing and proposed 100-year floodplain boundaries will be mapped so that any
impacts may be seen in relation to surroundings.
2. The Brushy Creek Watershed is currently being restudied-to update flooding conditions
therein. Atkins has been in contact with the Upper Brushy Creek Water Control and
Irrigation District (UBCWCID) staff and it is understood that preliminary updated
models might be available as early as July of 2012. Atkins will coordinate with the
UBCWCID and City staff to obtain the best available hydrologic and hydraulic modeling
information for use in the hydraulics impacts analysis. If the UBCWCI models camiot be
Page 7 of I 1
i
f
i
I
obtained, then other best available information will be used to evaluate the proposed
bridge impacts.
3. Based on the 100% design plans, and the best available information, Atkins will develop
a Conditional Letter of Map Revision (CLOMR) to document the changes to the 100-year
floodplain as a result of the proposed bridge and other related modifications. Atkins will
develop all necessary information including hydrologic and hydraulic modeling,
floodplain figures, and MT-2 Application forms, and a report summarizing analyses and
results. Our effort will also include responding to comments from both the applicable
floodplain administrator and FEMA reviewer to obtain CLOMR approval. After the
project i
p '� s constructed, a Letter of Map Revision will be developed and submitted to
FEMA to document the final grades and structural details of the bridge and other related
modifications that affect the floodplain determination. As with the CLOMR, the LOMR
work effort will produce all relevant hydrologic and hydraulic modeling, floodplain
mapping, the MT-2 Form, and a summaryM
report. Please note that the CLOR
application requires compliance with the Endangered Species Act, and may require a
letter from the United States Fish and Wildlife.
4. A potential scour assessment will be performed for the proposed bridge design. This
assessment will consider the gradation of the channel bed material, boring data, channel '
R
slope, channel shear and incipient motion of the average bed material. If this assessment i
indicates that there is a potential for scour, then a more detailed scour analysis will be
performed using either HEC-18 guidelines or the Texas Secondary Evaluation and
Analysis for Scour (TSEAS, 1993). If it is deterinined from this potential scour
assessment that a detailed scour analysis is required then additional set-vices may be
requested.
5. A technical memorandum documenting hydrologic and hydraulic modeling assumptions
for the bridge impacts, onsite drainage and water quality considerations will be provided. a
i
Onsite Drainage i
6. Onsite drainage plans including storm drains, inlets, outfalls and other associated
drainage considerations will be adjusted as required to comply with the City's review
com nients of the 30%design plans.
7. Provided that inlet filtration is used in lieu of a water quality pond, onsite drainage plans
will be amended to include inlet filtration locations, sizes, and other design details. I
Water Quality Considerations
8. As mentioned above, based on the 30%design effort it appears that there will be impacts
to the 100-year water surface elevation, in particular if the water quality pond is sited
under the bridge. Therefore, it is recommended that inlet filtration devices be used to
satisfy TCEQ water quality standards for construction over the Edwards Aquifer recharge e
zone. Atkins will coordinate with City staff to devise a water quality strategy using either ;
inlet filtration or a water quality pond. g
f`
9. As this project site is located over the Edwards Aquifer recharge zone, TCEQ requires a
WPAP be submitted to prove that the required pollutant removal rates are achieved for
proposed conditions. Atkins will meet and coordinate with both City and TCEQ staff
during the 60% design effort in order to obtain preliminary concurrence with the
Page 8 of l l
t
I
• I
proposed water quality strategy. Atkins will develop and submit the WPAP to TCEQ,
and respond to TCEQ comments as required to assist in obtaining TCEQ approval for the
construction of this project.
10. Atkins will provide Storm Water Pollution Prevention Plans(SWPPP)to minimize
sediment discharge from the project area during construction in accordance with best j
management practices,
11. Atkins will provide water quality construction plans and details sufficient to construct the
water quality elements for this project as agreed upon by City Staff and approved by
TCEQ.

NOT INCLUDED WITHIIN THIS SCOPE
The following items are not included with this scope because the level of effort to complete these ! 1
tasks is very dependent on the final route selected. These items, if necessary, would be added to
the scope through a supplemental agreement. l
1. A detailed scour analysis will not be performed; instead a potential scour analysis
considering channel bed material gradation, boring data, channel slope, channel shear and
incipient motion of the average bed material will be performed. i
2. Hydrologic and/or hydraulic modeling of the upstream watershed.
3. It is assumed that a water quality solution will be chosen that does not require any
structural design. If water quality ponds are included, additional scope will need to be
added for the structural design portion of the ponds.
4. Traffic signal design is not included in this effort.

5. Additional scope for presence/absence surveys for federally-listed karst invertebrates are
not included at this time as it is dependent upon potential participation in the RHCP and
coordination with USFWS.
6. Additional habitat evaluations for federally-listed species would be necessary oil ROW
segments not previously-evaluated. The habitat evaluation would include a Phase I Karst
Survey. If karst features are encountered, additional karst surveys (i.e., Phase 2 or Phase
3)would be covered under a separate scope of work and cost estimate, if necessary.
7. The project team currently assumes that Brushy Creek would be fiully spanned; if bridge
designs change and result in discharge of fill material below the ordinary high water mark
(OHWM) of Brushy Creek exceeding 0.10 acre, then a Pre-Construction Notification to
the US Army Corp of Engineers (USACE) would be necessary. Please note that the PCN
process would result in USACE coordination, report updates,permit acquisition,etc.,and
is not included within this scope. A scope for the USACE permit acquisition process
would be provided if changes to design exceed a discharge of 0.10 acre within Brushy
Creek's OHWM. Under NWP 14, discharges of fill within regulated waters over 0.10 A
acre would require PCN to the USACE, and NWP 14 allows for up to 0.50 acre of
discharge.
8. The project team assumes the project will be constructed using local funding sources and
will not require any federal permitting. As a result, no further documentation or f
coordination regarding non-archeological historic-age resources is included in the current f t
scope.
9. Water System Hydraulics, System Capacity, and Diameter Selection -- The CoRR Staff i
has evaluated and addressed these components of the project.
10. Water System Engineering Report- An engineering report is not anticipated for the water
transmission line project.
