SURVEY INFORMATION

USIBWC Contract No.: IBM09B0003 Page 00.31.21 - 1

AVAILABLE INFORMATION 00.31.21

For these Contract Drawings, surveying and data collection was performed as follows:

(1) Light Detection and Ranging (LiDAR) was obtained from the Government and used for preliminary information.

(2) Control was performed in April / May 2009 by RODS Surveying, Inc. who developed and provided the following (at .01-foot accuracy):

(a) Control. The surveyor established points at cross-roads to establish horizontal and vertical control; control sheets were developed for each control point set, signed and sealed by a Texas Registered Professional Land Surveyor (RPLS). The control sheet includes a drawing of the control point with a 3-point tie to existing physical features, description of the control point, X,Y & Z coordinates and the coordinate system. The Contract Drawings include the control information data for all the control points set for the project, signed and sealed by the

RPLS.

(b) Benchmarks. The surveyor established bench marks along project limits; vertical benchmarks were set at 1000-foot intervals at the right of way (ROW) line of the levee reach. A tabulation of the benchmarks is shown within the Contract Drawings.

(3) Supplemental ground surveys were performed by RODS Surveying, Inc.:

(a) Voids. A topographic survey was performed by the surveyors to fill-in the voids of the aerial planimetrics; additionally, the surveyor performed topographic survey on existing structures, including bridges, inlets, culverts and irrigation structures.

(b) ROW Verification. The surveyors recovered and staked ROW points from available ROW maps supplied by the Government. This ROW information is shown on the plan / profile sheets of the Contract Drawings.

(c) Geotechnical Borings Survey. The surveyors obtained x-y-x coordinates for the geotechnical borings along the levee reach spaced at approximately 500-foot spacings.

(d) Utility Survey. The surveyors coordinated with utility notification companies to get utilities marked in the field; the surveyor performed field location of underground utilities as marked by utility companies along the levee reach and intersecting streets. These locations are shown on the plan / profile sheets of the Contract Drawings. NOTE: IT IS THE CONTRACTOR’S

RESPONSIBILITY TO VERIFY LOCATIONS OF ALL EXISTING UTILITIES (SHOWN

AND NOT SHOWN ON THE CONTRACT DRAWINGS) PRIOR TO CONSTRUCTION.

ENVIRONMENTAL ASSESSMENT INFORMATION

USIBWC Contract No.: IBM09B0003 Page 00.31.24 - 1

AVAILABLE INFORMATION 00.31.24

ENVIRONMENTAL DOCUMENT INFORMATION

The Project’s environmental assessment entitled “Final Environmental Assessment, Alternatives for Improved Flood Control of the Hidalgo Protective Levee System, September 2005” is available for Contractor review upon request of the Contractor. The project is located adjacent to the Lower Rio Grande Valley National Wildlife Refuge (LRGV NWR), Pate Bend (352, 352A, 354B, & 354C) and Hidalgo Bend (354A, 354II, & 354) Tracts. Additional information is as follows:

1. Establishing and Acquisition Authorities. Various authorities include:

• Fish and Wildlife Act of 1956 [16 U.S.C. 742f(a)(4)], [16 U.S.C. 742f(b)(1)]

• An Act Authorizing the Transfer of Certain Real Property for Wildlife, or other purposes [16

U.S.C. 667b]

• Refuge Recreation Act, as amended [16 U.S.C. 460k-1], [16 U.S.C. 460k-2]

• Migratory Bird Treaty Act [16 USC 703]

• National Wildlife Refuge System Improvement Act of 1997

2. Refuge Purpose(s). As excerpted from the enabling legislation used to authorize the acquisition of the Refuge, the following are the Refuge purposes:

“... for the development, advancement, management, conservation, and protection of fish and wildlife resources...” [16 U.S.C. 742f(a)(4)] “... for the benefit of the United States Fish and Wildlife Service, in performing its activities and services. Such acceptance may be subject to the terms of any restrictive or affirmative covenant, or condition of servitude...” [16 U.S.C. 742f(b)(1)] (Fish and Wildlife Act of 1956)

”... particular value in carrying out the national migratory bird management program.” [16 U.S.C. 667b] (An Act Authorizing the Transfer of Certain Real Property for Wildlife, or other purposes)

”... suitable for: (1) incidental fish and wildlife-oriented recreational development, (2) the protection of natural resources, (3) the conservation of endangered species or threatened species...” [16 U.S.C. 460k- 1] “... the Secretary ... may accept and use ... real ... property. Such acceptance may be accomplished under the terms and conditions of restrictive covenants imposed by donors...” [16 U.S.C. 460k-2] (Refuge Recreation Act [16 U.S.C. 460k-460k-4], as amended)

”... for use as an inviolate sanctuary, or for any other management purpose, for migratory birds.” [16 U.S.C. 715d] (Migratory Bird Treaty Act, 16 USC 703)

3. Refuge Goals. The Lower Rio Grande Valley and Santa Ana National Wildlife Refuges Comprehensive Conservation Plan (CCP) of 1997 satisfies the CCP requirement of the National Wildlife Refuge System Improvement Act of 1997 and identifies the following five goals of the Lower Rio Grande Valley National Wildlife Refuge:

• To restore, enhance and protect biological diversity.

• To protect and obtain additional water rights, improve water management, and protect, restore and enhance wetlands.

Rehabilitation of Hidalgo Protective Levee (Modified Phases I and II) and Banker Floodway South Levee

ENVIRONMENTAL ASSESSMENT INFORMATION

USIBWC Contract No.: IBM09B0003 Page 00.31.24 - 2

• To improve water quality and reduce contaminant related fish and wildlife resource losses.

• To protect, maintain and plan for cultural resources.

• To offer compatible wildlife dependent public uses, recreational opportunities, and interpretation and education.

4. National Wildlife Refuge System Mission. “The Mission of the National Wildlife Refuge System is to administer a national network of lands and waters for the conservation, management, and where appropriate, restoration of the fish, wildlife, and plant resources and their habitats within the United States for the benefit of present and future generations of Americans.”

5. Description of Use. It is anticipated that no use of LRGV NWR property will be required for the construction of the Project.

6. Availability of LRGV NWR Resources. It is anticipated that no use of LRGV NWR resources will be required for the construction of the Project.

7. Anticipated Impacts of the Use. It is anticipated that no use of LRGV NWR property will be required for the construction of the Project.

8. Public Review and Comment. It is anticipated that no use of LRGV NWR property or resources will be required for the construction of the Project; therefore, no public review or comment period will be required.

9. Other considerations. The Contractor is required to adhere to the following:

(a) No excavation event should be performed on LRGV NWR property. If during construction it is found that there is a need to perform construction on LRGV NWR property, the Contractor shall not begin construction without obtaining a Special Use Permit from the LRGV NWR or without the notification of the activity to the Refuge Manager; all federally mandated consultations and the procurement of permits will be completed by the Government, including, but not limited to, those required by the U.S. Army Corps of Engineers and the Texas State Historic Preservation Office.

(b) Vegetated areas will be clearly marked by an environmental monitor and work activities will avoid these areas.

(c) Proper training will be given to machine operators to reduce the risk of accidental mortality to less mobile terrestrial wildlife.

(d) While work is being conducted, vehicles and equipment will be monitored continuously to insure that fuels, oils and fluids do not leak or are spilled onto the ground. In the event of a spill or leak, the Refuge Manager will be immediately notified, all work activities will be suspended until the spillage or leakage is stopped and appropriate clean-up measures are employed to capture contaminants and remove contaminated soils.

(e) All other stipulations and/or rules from “General Conditions and Operating Procedures While on the Lower Rio Grande Valley National Wildlife Refuge” will be strictly adhered to.
