( Torracon) 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:1V). 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 steoper than 3H.1 V. <br />B. 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 [2811 557 2900 F [2811 557 2990 terracon,com <br />
