City Manager Approval - December 9, 2005
Consider an action by the City Manager to execute United
States Army Corps of Engineers (USACE) Permit for the
construction of channel improvements and
implementation of a mitigation plan for the Dry Branch
(South Creek Channel) Improvements project.
Department: Engineering & Development Services
Staff Person: Daniel L. Ha!den, P.E., City Engineer
Michael D. Thane, P.E., Senior Engineer
Justification: This project includes the construction of approximately 6,540
linear feet of Dry Branch tributary to correct problems of bed scour and bank
stability, as well as to address concerns of public safety associated with flooding.
The Dry Branch Project will impact 2.24 acres of waters of the U.S., and as a result,
the City has undertaken to secure a permit from the Corps of Engineers having
jurisdiction over the Dry Branch project.
The City of Round Rock is constructing the channel modifications on approximately
4,160 linear feet and D.R. Horton, the developer of the Turtle Creek subdivision, is
constructing channel modifications on approximately 2,380 linear feet of the
channel. Because the City of Round Rock is the only applicant for the permit, a
Developer Agreement with D.R. Horton was executed to ensure the permitted
activities for this project are completed by both parties in a timely manner.
Funding:
Cost: None
Source of funds: Not Applicable
Outside Resources: United States Army Corps of Engineers (USACE)
D.R. Horton - Developer of Turtle Creek Subdivision
Background Information: The Dry Branch Project will consist of widening
approximately 4,000 linear feet of natural stream channel, construction of a low
flow channel in approximately 2,540 linear feet of previously channelized stream
channel, and implementation of a mitigation plan concurrently with construction
and operation of the Dry Branch project to offset adverse impacts to waters of the
U.S.
Public Comment: The City has discussed the proposed project with several
residents in the South Creek subdivision. A neighborhood meeting will be
conducted prior to the commencement of construction for residents whose property
is adjacent to the Dry Branch.

Attachment 1 - Dredge and Fill Certification
USACE Permit No. 200200684
August 5, 2005
Page 1 of 2
WORK DESCRIPTION: As described in the public notice dated September 24, 2004, and the July 7,2005,
Decision Document.
SPECIAL CONDITIONS: None.
GENERAL: This certification, issued pursuant to the requirements of Title 30, Texas Administrative
Code, Chapter 279, is restricted to the work described in the application or joint public notice and shall
expire five years from the date of issuance of the Corps of Engineers (COE) permit. This certification may
be extended to any minor revision of the COE permit when such change(s) would not result in an impact on
water quality. The Texas Commission of Environmental Quality (TCEQ) reserves the right to require full joint
public notice on a request for minor revision. The applicant is hereby placed on notice that any activity
conducted pursuant to the COE permit which results in a violation of the state's surface water quality standards
may result in an enforcement proceeding being initiated by the TCEQ or a successor agency.
STANDARD PROVISIONS: These following provisions attach to any permit issued by the Corps of
Engineers and shall be followed by the permittee or any employee, agent, contractor, or subcontractor of the
permittee during any phase of work authorized by a Corps permit.
1. The water quality of wetlands shall be maintained in accordance with all applicable provisions of the
Texas Surface Water Quality Standards including the General, Narrative, and Numerical Criteria.
2. The applicant shall not engage in any activity which will cause surface waters to be toxic to man, aquatic
life, or terrestrial life.
3. Permittee shall employ measures to control spills of fuels, lubricants, or any other materials to prevent
them from entering a watercourse. All spills shall be promptly reported to the TCEQ, Emergency Spill
Response, at (512) 463-7727.
4. Sanitary wastes shall be retained for disposal in some legal manner. Marinas and similar operations
which harbor boats equipped with marine sanitation devices shall provide state/federal permitted
treatment facilities or pump out facilities for ultimate transfer to a permitted treatment facility.
Additionally, marinas shall display signs in appropriate locations advising boat owners that the discharge
of sewage from a marine sanitation device to waters in the state is a violation of state and federal law.
5. Materials resulting from the destruction of existing structures shall be removed from the water or areas
adjacent to the water and disposed of in some legal manner.
6. A discharge shall not cause substantial and persistent changes from ambient conditions of turbidity or
color. The use of silt screens or other appropriate methods is encouraged to confine suspended
particulates.
7. The placement of any material in a watercourse or wetlands shall be avoided and placed there only with
the approval of the Corps when no other reasonable alternative is available. If work within a wetland is
unavoidable, gouging or rutting of the substrate is prohibited. Heavy equipment shall be placed on mats
to protect the substrate from gouging and rutting if necessary.
8. Dredged Material Placement: Dredged sediments shall be placed in such a manner as to prevent any
sediment runoff onto any adjacent property not owned by the applicant. Liquid runoff from the disposal
area shall be retained on-site or shall be filtered and returned to the watercourse from which the dredged
materials were removed. Except for material placement authorized by this permit, sediments from the
project shall be placed in such a manner as to prevent any sediment runoff into waters in the state,
including wetlands.

9. If contaminated spoil that was not anticipated or provided for in the permit application is encountered
during dredging, dredging operations shall be immediately terminated and the TCEQ, Emergency Spill
Response, shall be contacted at (512) 463-7727. Dredging activities shall not be resumed until
authorized by the Commission.
10. Contaminated water, soil, or any other material shall not be allowed to enter a watercourse.
Noncontaminated storm water from impervious surfaces shall be controlled to prevent the washing of
debris into the waterway.
11. Storm water runoff from construction activities that result in a disturbance of one or more acres, or are
a part of a common plan of development that will result in the disturbance of one or more acres, must
be controlled and authorized under Texas Pollutant Discharge Elimination System (TPDES) general
permit TXR150000. A copy of the general permit, application (notice of intent), and additional
information is available at: http://www.tnrcc.state.tx.us/permitting/waterperm/wwperm/construct.html or
by contacting the TCEQ Storm Water & Pretreatment Team at (512) 239-4433.
12. Upon completion of earthwork operations, all temporary fills shall be removed from the
watercourse/wetland, and areas disturbed during construction shall be seeded, riprapped, or given some
other type of protection to minimize subsequent soil erosion. Any fill material shall be clean and of such
composition that it will not adversely affect the biological, chemical, or physical properties of the receiving
waters.
13. Disturbance to vegetation will be limited to only what is absolutely necessary. After construction, all
disturbed areas will be revegetated to approximate the pre -disturbance native plant assemblage.
14. Where the control of weeds, insects, and other undesirable species is deemed necessary by the
permittee, control methods which are nontoxic to aquatic life or human health shall be employed when
the activity is located in or in close proximity to water, including wetlands.
15. Concentrations of taste and odor producing substances shall not interfere with the production of potable
water by reasonable water treatment methods, impart unpalatable flavor to food fish including shellfish,
result in offensive odors arising from the water, or otherwise interfere with reasonable use of the water
in the state.
16. Surface water shall be essentially free of floating debris and suspended solids that are conducive to
producing adverse responses in aquatic organisms, putrescible sludge deposits, or sediment layers
which adversely affect benthic biota or any lawful uses.
17. Surface waters shall be essentially free of settleable solids conducive to changes in flow characteristics
of stream channels or the untimely filling of reservoirs, lakes, and bays.
18. The work of the applicant shall be conducted such that surface waters are maintained in an aesthetically
attractive condition and foaming or frothing of a persistent nature is avoided. Surface waters shall be
maintained so that oil, grease, or related residue will not produce a visible film of oil or globules of grease
on the surface or coat the banks or bottoms of the watercourse.
19. This certification shall not be deemed as fulfilling the applicant's/permittee's responsibility to obtain
additional authorization/approval from other local, state, or federal regulatory agencies having
special/specific authority to preserve and/or protect resources within the area where the work will occur.
