(Terracon) understands that we have been selected based on <br /> qualifications to provide Geotechnical Engineering Services for the above referenced project. This <br /> document outlines our understanding of the scope of services to be performed by Terracon for this <br /> project and provides an estimate of the cost of our services. <br /> A. PROJECT INFORMATION <br /> Plans are to improve approximately 3,800 linear feet of drainage ditch along an existing Harris <br /> County Flood Control Easement within Battleground Estates Subdivision in La Porte, Texas. As part <br /> of the improvement program, the existing drainage ditch is planned to be widened. We understand <br /> the proposed drainage channel depth will be approximately 8 feet, with sideslopes no steeper than <br /> 4 horizontal to 1 vertical (4H:1 V). We also understand that the drainage ditch will not be maintained by <br /> Harris County Flood Control District (HCFCD) or any other jurisdiction that has specific requirements <br /> for Geotechnical Engineering Services. Therefore, our Geotechnical Engineering Services will not be <br /> performed to meet the requirements of the HCFCD. <br /> In addition, roadside ditches are also planned to be reconstructed along Bois D'Arc Drive, We <br /> understand that the maximum depths of the proposed roadside ditches are planned to be 5 feet, with <br /> sideslopes no steeper than 3H:1 V. <br /> O. SCOPE OF SERVICES <br /> A brief summary of the services to be provided by Terracon is presented in the following <br /> paragraphs. <br /> Terracon Consultants, Inc. 551 Link Road, Suite F League City, Texas 77573 <br /> P [281] 557 2900 F [281] 557 2990 terracon.com <br /> Geotechnical III Environmental • Construction Materials 11 Facilities <br />
