Re: Phase I Cultural Resources Study
Hike and Bike Trail along Goose Creek, Baytown, Texas
Owner: City of Baytown
HVJ Proposal No. 02- 121PEH -1
Dear Mr. Perry:
6120 S. Dairy Ashford
Houston, Texas 77072
Voice: 281- 933 -7388
Fax: 281- 933 -7293
httpJ/www.hvj.com
HVJ Associates Inc. is pleased to present this proposal for providing the additional referenced
environmental services for the Hike and Bike Trail along Goose Creek in Baytown, Texas. This
additional work is required based on a review of the TxDOT PALM document and consultation
with the Texas Historical Commission (THC).
The proposed trail will be 10 -feet wide and about 2 miles in length. It will start at the Texas
Avenue Bridge over Goose Creek at Goose Creek Park and will follow the existing 8 -foot wide
trail (to be widened to 10 feet) to the Decker Drive /Garth Road intersection. The trail will cross
Decker Drive and then spilt into two trails. One trail will continue along Garth to Central Little
League Park, then southeast to an existing trail on the south side of the Park. The other trail will
continue along Decker Drive to Goose Creek and meander with the creek through an
undeveloped area and cross Park Street. On the other side of Park Street, this segment will
continue around the Park Service Center, traverse a natural drainage swale, proceed eastward
behind a nursing home, Goose Creek Place apartments, and then along an undeveloped right of
way (Shilling Street) and end at Garth Road.
HVJ Associates understands that the project will be developed in accordance with TxDOT
procedures.
Phase I Cultural Resources Survey
The Cultural Resources Survey will include the following:
• Obtain a THC Antiquities Permit. This permit is required prior to conducting
archaeological work on State lands or any of its subdivisions (the permit application
will be sent to TxDOT for approval prior to submittal to the THC);
• Perform Cultural Resources Background Research for the Area of Potential Affect
(APE);
• Perform a Phase I Cultural Resources Survey on the APE. This will entail conducting
shovel testing as required by the THC. All testing of this nature will follow the
Council of Texas Archaeologists guidelines;
• Present findings and recommendation as appropriate; and
• Submit 20 copies of the final report to the TxDOT.
Mr. Chip Perry.
HVJ Proposal No. 02- 121PEH -1

Cost and Schedule
The lump sum fee for this additional service is $7;000. Six to eight weeks (depending on
response(s) from state agencies and logistics) will be required for conducting this survey. A
detailed breakdown of the costs associated with this additional work is attached.
Conditions
Insurance certificates verifying HVJ Associates' general liability, auto, workers' compensation,
and errors and omissions insurance coverage, listing Halff Associates, Inc. as a certificate holder,
will be provided upon request. Our accounting procedures call for the submittal of invoices on a
month -end basis or at the conclusion of project should its .duration last less than a month.
