EDWARDS AQUIFER RECHARGE ZONE MAP
CREEK BEND BOULEVARD EXTENSION
WILLIAMSON COUNTY, TEXAS
Attachment C
Project Description
The City of Round Rock in cooperation with the Texas Department of Transportation (TxDOT)
proposes to extend the existing Creek Bend Boulevard from Creek Bend Circle to Wyoming
Springs Drive (CSJ 0914-05-150). The project corridor (defined as the Creek Bend Boulevard
extension) is approximately 0.44 mile in length and is located in Williamson County in central
Texas (see Attachment A). The proposed new location roadway would consist of extending the
existing four -lane divided arterial with a bridge over Brushy Creek. Creek Bend Boulevard would
connect to Brightwater Boulevard, which has an identical section, a four -lane divided roadway
with a raised median. The project also includes possible modifications to and realignment of
Hairy Man Road/Brushy Creek Road (hereafter referred to as Hairy Man Road). The proposed
Hairy Man Road realignment would run approximately 970 feet northwest from the proposed
Creek Bend Boulevard extension and would transition into the existing Hairy Man Road. The
existing Hairy Man Road bridge is to be removed and a section of Hairy Man Road permanently
closed to vehicular traffic via a cul-de-sac at the proposed terminus.
The proposed project is included in the Capital Area Metropolitan Planning Organization
(CAMPO) 2008-2011 Transportation Improvement Program (TIP) (CAMPO, 2006 [adopted
February 12, 2007]). The funding category is 7 — Surface Transportation Program (STP)
Metropolitan Mobility, which consists of transportation projects intended to improve mobility.
Traffic projections for the proposed Creek Bend Boulevard extension were obtained from the
CAMPO Model Estimate: Model Version 2006-2030 Amended Plan. The traffic volumes along
this roadway indicates the average daily traffic (ADT) for the base year 2007 as being 25,000
vehicles per day (VPD) and 2030 traffic is projected to be approximately 40,000 VPD.

Surface Soils Description
Attachment B
Surface Soils Description
Naturally occurring surface soils within the proposed Creek Bend Boulevard Extension Project, referred
to herein as the project area, are very thin and contain limestone cobbles. This layer (2-8 inches thick) is
formed over a soft to hard limestone bedrock, and is typical in the upland areas. Engineering and
hydrologic properties of these soils are presented in Table B-1.
According to the Soil Survey of Williamson County (Soil Conservation Service [SCSI, 1983) the project
area is situated on the Eckrant cobbly clay (EaD), Eckrant extremely stony clay (EeB), Eckrant-rock
outcrop complex (ErE), Georgetown stony clay loam (GsB), and Oakalla soils (Oc). A soils map is
presented as Figure B-1.
The EaD soil has a 1 to 8 percent slope and is on undulating uplands. Typically, the surface layer is about
13 inches thick. The lower part is dark brown cobbly clay and the underlying material is coarsely
fractured indurated limestone. The EaD soil is calcareous and moderately alkaline. The surface has
approximately 50 percent cover of fragments of limestone that are mostly 4 to 8 inches across. This soil
well drained and permeability is moderately slow with rapid runoff. The available water capacity is very
low.
The EeB soil has a 0 to 3 percent slope and is on nearly level to gently sloping areas with broad ridges
and shallow valleys on uplands. Typically, this soil has an extremely stony, very dark gray clay surface
layer about 11 inches thick. The underlying material is indurated limestone with approximately 25 percent
of the surface covered with fragments of limestone that are about 6 inches across but range from 3 inches
to 3 feet across and are as much as 10 inches thick. This soil is calcareous and moderately alkaline. This
soil well drained and permeability is moderately slow with rapid runoff. The available water capacity is
very low because of the shallowness of the soil and stones in the soil.
The ErE rock outcrop complex is found on uplands consisting of Eckrant soils and rock outcrop found on
hills, ridges, and drainage ways. The soils and rock outcrop are so intricately mixed or so small in area,
that mapping them separately was not practical. The slopes range from 5 to 16 percent. This complex is
made up of 70 percent Eckrant soils, 15 percent rock outcrop, and 15 percent other soils. Typically, the
surface layer of the Eckrant soils is calcareous moderately alkaline, dark grayish brown extremely stony
clay about 8 inches thick. The underlying material is fractured indurated limestone. Fragments of
limestone from 6 inches to 2 feet across cover about 35 percent of the surface. The rock outcrop consists
of exposed limestone bedrock. Loose cobbles and stones on the surface are common. Permeability is
moderately slow with rapid runoff. The available water capacity is very low.
The GsB soil has a 0 to 2 percent slope and is on nearly level to gently sloping areas on uplands.
Typically, the surface layer is slightly acid brown clay loam approximately 7 inches thick. The subsoil

cobbly clay in the lower part. The underlying material is indurated limestone that has limy earth
imbedded in the crevices. This soil is well drained and permeability is slow with medium runoff. The
available water capacity is low.
The Oc soils, channeled, are on bottom lands in narrow stream valleys. The bottom lands are dissected by
numerous channels that are 2 to 6 feet deep, 10 to 30 feet wide and 50 to 500 feet apart. The side slopes of
the channels range from approximately 8 percent in gradient to nearly vertical. The soil has a slope of 0 to
1 percent. Typically, the surface layer is dark brown loam about 7 inches thick. The layer below is dark
brown clay loam about 16 inches thick. The underlying soil layer to 66 inches is dark brown sandy clay
loam. The soil is calcareous and moderately alkaline. These soils are flooded for very brief to brief
periods in most years. These soils are well drained and permeability is slow with medium runoff. The
available water capacity is high.

NARRATIVE OF SITE SPECIFIC GEOLOGY
CREEK BEND BOULEVARD EXTENSION PROJECT
ROUND ROCK, WILLIAMSON COUNTY, TEXAS
1.0 INTRODUCTION
A geologic assessment of the proposed Creek Bend Boulevard Extension Project was conducted by
PBS&J pursuant to Texas rules for regulated activities on the Edwards Aquifer Recharge Zone (30 TAC
213). Assessment findings were used to develop recommendations for site construction measures
intended to be protective of water resources at the site and adjacent areas. Sixteen geologic features were
identified within the project site. No manmade features were found.
1.1 PROJECT DESCRIPTION
The proposed site development application is for an extension of Creek Bend Boulevard from Creek Bend
Circle to Brightwater Boulevard. The project would consist of continuing the four -lane divided arterial
street with a proposed bridge over Brushy Creek and the proposed realignment of Hairy Man Road. The
project area is located within an undeveloped tract immediately northeast of the intersection of Wyoming
Springs and Brightwater Boulevard in Round Rock, Williamson County, Texas.
1.2 GEOLOGIC ASSESSMENT SCOPE
The geologic assessment was conducted in July 2008, and included the following data collection and
evaluation tasks:
• Published geological and/or hydrological reports for the Williamson County area were reviewed.
• Texas Water Development Board records were reviewed for infonnation about water wells at the
project site.
• A field survey was conducted by a registered professional PBS&J geologist in March and April,
2007 to identify hydrologically sensitive geologic and manmade features at the site. The survey
consisted of walking the entire project site. Additionally, a Phase II Karst Survey was performed
by PBS&J geologists in June 2007 to further define each feature's sensitivity.
2.0 SITE GEOLOGY
The project site is located within the Edwards Aquifer Recharge Zone (EARZ) defined by the Texas
Commission on Environmental Quality (TCEQ). The EARZ occurs where surface water enters the
subsurface through exposed limestone bedrock containing faults, fractures, sinkholes, and caves. The
project area is underlain by approximately 150 to 175 feet of the Edwards Limestone Formation.
441200/080168 D-1
The Edwards Limestone Formation (Ked) is the thickest and most permeable of several stratigraphic units
that comprise the Edwards aquifer. Composed of relatively pure limestone and dolomite, the Edwards
Formation weathers mainly by dissolution and contains solution features such as honeycombing,
sinkholes, and caves. In some areas, the formation is extensively faulted. These characteristics allow for
rapid infiltration of surface water on the outcrop, and for rapid movement of groundwater within the
aquifer. The Edwards Limestone Formation (Ked), is fine- to coarse-grained, gray to grayish -brown,
fossiliferous (rudistids, milliolids and shell fragments), thick -bedded to massive, and cherry. Solution
zones and collapse breccias are common.
2.1 TOPOGRAPHY AND SURFACE DRAINAGE
The project site is located on gently to moderately sloping terrain, which drains primarily to the north-
northeast toward Brushy Creek. Surface elevations in the project site vary from a minimum of
approximately 730 feet above mean sea level (msl) along Brushy Creek to a maximum of approximately
805 feet msl at the southwest end (Wyoming Springs Drive).
2.2 STRUCTURAL GEOLOGY
The structural geology of the region is dominated by normal faults of the Balcones fault zone, which have
a predominant northeast strike. The rock strata beneath the site dip to the east-northeast at about 50 feet
per mile (less than 1°), and the northeast -trending Balcones Fault Zone is located about one mile east of
the site.
Mapping by the Bureau of Economic Geology (BEG) indicates one, geologically inactive normal fault
located about 0.25 mile northeast of the project area (BEG, 1974). A normal fault is an inclined fault in
which the hanging wall appears to have slipped downward relative to the footwall. Additional faults are
located further to the northeast and southeast of the project site within the Balcones Fault Zone.
2.3 STRATIGRAPHY
The Edwards Limestone outcrop at the site's surface within knoll -like upland contours, and is underlain
by the Upper Glen Rose. A stratigraphic column is included as Attachment C to the geologic assessment.
2.4 GEOLOGIC AND MANMADE FEATURES
A field survey of the project site was conducted by PBS&J geologists in March and April 2007. A total of
sixteen geologic features occur within the project site. No man made features were identified within the
project site.
As previously discussed, a Phase II investigation of known site karst features was conducted in June 2007
by qualified PBS&J geologists (Figure D-1). An excavation of each feature was performed using hand
tools only. These features would have been left open after excavation; however, the features (except F-8)

were backfilled at the landowners request with rocks to prevent injury to his livestock. The results of the
investigation are as follows:
F-1: This feature was excavated to a maximum depth of 3 feet when the excavation was terminated upon
encountering massive, hard clay packed infilling containing a thick root matrix. A heavy metal bar, which
was used to probe the fill, encountered a solid rock bottom at 4 feet below ground level. Closure of this
feature consisted of backfilling with variable size stones level with the surrounding ground surface.
F-2: This feature was excavated at each end of the rock joint to a depth of 1.5 feet, encountering a
massive infilling of hard packed clay containing a thick root matrix. A solid rock bottom was detected by
probing with the bar at 2 feet, as the walls of the joint beneath the fill taper inward to joint closure at the
center. Closure was by stone backfilling to surrounding ground level.
F-3: An attempt to excavate this solution -enlarged fracture was made; however, narrowing solid walls of
the fracture prevented reaching the fill materials beyond a depth of 3 feet. The fill was compacted clay
with a thick root matrix. The bar probe indicated joint closure at approximately 4 feet. Closure was by
stone backfilling to level grade.
F -3A: This solution -enlarged fracture was excavated to a maximum depth of 3 feet, to reveal the rock
joint closed to a thin fracture. Closure was stone backfilling to level grade.
F -3B: This solution -enlarged fracture was probed to a depth of only 10 inches to reveal a solid floor and
the closure of the rock joint. The feature was left non -excavated based upon this result.
F -3C: This solution -enlarged fracture was probed to a depth of 14 inches to a solid rock bottom and
closure of the rock joint. The feature was left unexcavated based upon this result.
F -3D: This solution -enlarged fracture was excavated to a maximum depth of 1.5 feet, when further
probing revealed a solid rock bottom at 2 feet below grade. Closure was by stone backfilling to level
grade.
F -3E: This solution -enlarged fracture was excavated at the northwest end to a depth of 2 feet, and further
probing in the massive fill revealed a solid rock bottom and closure of the rock joint at 3 feet. Closure was
by stone backfilling to level grade.
F -3F: This solution -enlarged fracture was excavated to a depth of 3 feet, revealing a solid rock bottom
and closure of the rock joint. Closure was by stone backfilling to level grade.
F -3G: This solution -enlarged fracture was excavated to a depth of 3.5 feet and remained filled with hard
packed clay and thick root matrix. Probing revealed a narrowing angular rock joint at 4 feet. Closure was
by stone backfilling to level grade.
441200/080168 D-4
F -3H: This solution -enlarged fracture was excavated to a depth of 1.5 feet, through hard packed clay
infilling with thick root matrix. The remaining fill was probed to a solid rock bottom at 2 feet. Closure
was by stone backfilling to level grade. Two smaller adjacent sink depressions were also excavated
revealing identical results, and were stone backfilled.
F -3I: This solution -enlarged fracture was excavated to a depth of 2.5 feet, at which a solid rock bottom
was encountered and exposed. All rock jointing was tightly closed. Closure was by stone backfilling to
level grade.
F-6: This sinkhole was excavated to a depth of 1 foot at which point the partially exposed portal through
solid bedrock was exposed and revealed to be too small to pursue further. At this point, the feature's
interior was probed vertically with the bar to reveal a thick infilling to the 3.5 foot depth, and narrow rock
sides. The excavation was terminated and the feature was closed by stone backfilling to level grade.
F -6A: This adjacent sinkhole was excavated to a depth of 1 foot, at which point the rock joint portal
narrowed to only 1 inch wide. Probing in the joint revealed a clay infilling and joint closure at 1.5 foot
depth. Closure was by stone backfilling to level grade.
F-7: This sinkhole was excavated to a depth of 1.5 feet at which a solid bedrock bottom was encountered.
The excavation was extended over towards the center of the surface depression, which revealed a very
small portal (6 -inch -diameter). This area was excavated down to an additional 2 feet where a rock bottom
with small clay filled fracture only 0.5 inch wide was observed. At this point, this excavation point was
abandoned and a new hole was dug directly over the center low point of the surface sink depression. This
excavation went down through massive hard packed clay with thick root matrix to the 3 -foot depth level,
and encountered the top of a rock lined portal only 8 inches in diameter at the top of the bedrock. This
portal remained massively filled and the excavation was terminated at a point where fill removal by hand
was no longer possible. The portal was probed to the 4 -foot depth level, and remained massively filled.
Closure of both excavation points were by stone backfilling to level grade.
F-8: The excavation of this sinkhole was conducted after a large volume of brush debris was removed to
reveal the natural surface expression of the karst feature. The feature was excavated to a depth of 7 feet
when a breakthrough into an underlying open void space occurred. The opening into the void space is
surrounded by solid rock beneath and at the center of the headwall (south) side of the sink. This portal
opens into a low room approximately 30 feet wide which stair steps down at an angle to the southeast.
Access is difficult due to the narrow horizontal passage between the floor and the ceiling. The initial
exploration extended short distances to each side, and about 12 feet downslope to a narrow constriction.
Beyond this constriction is another low, wide room which was not accessed at this point of the
investigation.
A second trip to the sinkhole on June 27, 2007 resumed the investigation with a lengthy, but successful
in -cave dig which opened an access to the lower room. This room extended another 15 feet ahead as a low
wide area to a central point at the back where a small drain portal continues through a constriction too low
441200/080168 D-5
PBSI
to follow. A well defined wash path in the center of the floor of the lower room leads directly to the
constriction. Slight to moderate airflow conductivity issuing from the portal indicates that the cave
continues for an unknown distance beyond. An underground survey of the cave was performed using a
Suuntos magnetic compass/inclinometer and tape measure. This feature has been given the name Creek
Bend Cave for identification purposes.
The karst features F -3A to F -3I were classified in the initial karst survey as a cluster as defined by EAPP
guidance. However, after further investigation, these features were found to lack subsurface development
and do not warrant designation as a cluster. Therefore, these features, which are predominately epikarsts,
are now classified as individual features. The Phase II karst survey revealed that only one karst feature,
F-8, is classified as sensitive in terms of point recharge to the Edwards Aquifer. This classification
criterion has been established by the Edwards Aquifer Protection Program (EAPP) within the TCEQ. The
classification of "sensitive" to a karst feature typically requires that a natural buffer with a radius of 50-
150 feet be established around the footprint of the feature. The remaining geologic features are classified
as not sensitive and would not require a natural buffer.
Sensitive karst features should be protected from the potential impacts of storm water runoff derived from
any type of construction that disturbs the ground surface. The best protection of these features is provided
by a natural buffer area size based on the catchment area for the feature. Temporary runoff protection
measures should be installed as near the construction as possible to minimize disturbance within buffer
zones and drainage areas.
According to the Texas Water Development Board electronic database, no water wells were found within
the subject property (TWDB, 2008).
3.0 CONCLUSIONS AND RECOMMENDATIONS
Sixteen geologic features were found and/or observed within the site boundaries, one (F-8 — Creek Bend
Cave) of which appears to be sensitive in terms of aquifer point recharge. A natural buffer with a radius of
approximately 50 feet should be established around the footprint of this feature (Creek Bend Cave). The
remaining karst features, which are not classified as sensitive, do not require protection. However, three
features (F -3G, F -3H, and F -3I) are located within the proposed right of way and will require appropriate
closure. This closure requires the removal of loose rock and the placement of compactable, fine-grained
soil in appropriate lifts to bring the ground surface to proposed grade.
The site generally appears suitable for the proposed development. It should be noted that soil and
drainage erosion would increase with ground disturbance. Native grasses and the cobbly content of the
soil aid to prevent erosion. Soil and sedimentation fencing should be placed in all appropriate areas prior
to any site construction activities.
441200/080168 D-6
Because the project site is located over the Edwards Aquifer Recharge Zone, it is possible that subsurface
voids underlie the site. The nature of the subgrade is fault influenced, which can result with variable sized
voids in materials that may otherwise not be noted as void or cave forming. If any subsurface voids are
encountered during subsurface activities, construction should halt immediately so a geologist may assess
potential for the void(s) to provide meaningful recharge to the Edwards Aquifer.

Creek Bend Circle to Wyoming Springs Drive
DATE: August 20, 2008
SUBJECT: City Manager - August 22, 2008
ITEM: Consider executing a Recharge and Transition Zone Exception
Request with the Texas Commission on Environmental Quality (TCEQ)
for the Creek Bend Blvd Extension Project.
Department: Transportation Services
Staff Person: Thomas G. Martin, P.E., Director
Justification:
TCEQ is requiring the City to submit an exception request for review of the Geologic
Assessment in advance of the Water Pollution Abatement Plan (WPAP). TCEQ will determine
if the Karst features discovered in the proposed project right-of-way will affect the roadway
alignment.
Funding:
Cost: $500.00
Source of funds: 2001 G.O. Bond
Outside Resources:
PBS&J, Inc.
Background Information:
The extension of Creek Bend Blvd from Creek Bend Circle to Wyoming Springs Drive
includes construction of a 4 -lane divided arterial roadway with curb and gutter, a bridge
over Brushy Creek, bicycle/pedestrian facilities within the right-of-way and drainage and
adjustments to utilities. This roadway extension will provide a new north -south crossing of
Brushy Creek west of IH 35, which will improve mobility, add travel capacity, improve safety
by providing an all-weather crossing of Brushy Creek between IH 35 and Parmer Lane and
improve emergency response times.
