CivilTech Engineering, Inc. was contracted by the Harris County Flood Control District to prepare a Comprehensive Master Drainage Plan for the Vogel Creek Watershed. Vogel Creek, HCFC Unit E121-00-00, is a tributary of White Oak Bayou in northwest Harris County. The Vogel Creek Watershed encompasses 9.8 square miles in the northwest part of the City of Houston and Harris County, Texas with over 80 percent of the watershed urbanized with residential and commercial land uses. The Vogel Creek Watershed has experienced a long history of flooding from storm water runoff exceeding the flood carry capacity along the creek. The Comprehensive Master Drainage Plan identifies and evaluates alternative flood reduction plans for Vogel Creek. Channel improvements were the primary flood reduction measures considered along Vogel Creek to solve the existing flood problems. Ten channel improvement plans were evaluated to provide a 100-year level of flood protection along the channel.

CivilTech Engineering, Inc., in association with EarthTech, Inc. and LJA Engineering & Surveying, Inc., was contracted by the Harris County Flood Control District to perform a General Re-evaluation Study for Brays Bayou, HCFC Unit D100-00-00. The Brays Bayou Watershed drains an area of approximately 128 square miles. CivilTech performed the economic re-evaluation in accordance with the federal objective for flood damage reduction studies. The economic re-evaluation includes an assessment of the flood damage potential in the watershed and determines the flood reduction benefits associated with the proposed alternative plans. The study procedures and methodology were in accordance with the U.S Army Corps of Engineers' Planning Study Guidelines for Civil Works and applicable Engineering Regulations and Manuals. Economic feasibility is determined on the basis that the project benefits exceed the project costs (B/C>1).

CivilTech Engineering, Inc. was contracted by the Harris County Flood Control District and the Houston District of the Texas Department of Transportation to prepare plans, specifications, and estimates (PS&E) for 4,500 linear feet of channel improvements to Jackson Bayou, HCFC Unit R100-00-00. The project limits extend from Ramsey Road to U.S. Highway 90 in Crosby, Texas. The proposed project will relieve existing flooding along Runneburg Road, primarily in the Runneburg Estates Subdivision, by redirecting stormwater runoff from the U.S. Highway 90 right-of-way into Jackson Bayou. The project will also provide additional flow capacity for the future expansion of the main lanes along US Highway 90. CivilTech performed a feasibility study to identify various drainage alternatives to alleviate drainage and flooding problems in the Runneburg Estates Subdivision. The recommended plan includes enlarging the channel from 600 feet downstream of Runneburg Road to Ramsey Road, and the extension of the channel to U.S. Highway 90.

CivilTech Engineering, Inc., in association with Lockwood, Andrews & Newnam, Inc., was contracted by the Yoakum District of the Texas Department of Transportation to prepare plans, specifications, and estimates (PS&E) for 12 miles of highway widening along U.S. 77, from Garcitas Creek to FM 682, in Victoria, Texas. CivilTech was responsible for performing the drainage design and hydraulic analysis for the proposed highway widening. The highway crosses stream channels at four bridges and 14 culvert drainage structures. Detailed hydrologic and hydraulic analyses were performed to determine existing hydraulic capacity and need for replacement. Construction plans were developed for the bridges and culvert structures. Hydraulic data sheets and bridge scour evaluations were completed for the bridges..

CivilTech Engineering, Inc., in association with Sylva Engineering Corporation and Brown & Gay Engineers, Inc., was contracted by the Austin District of the Texas Department of Transportation to prepare plans, specifications, and estimates (PS&E) for 1.5 miles of highway widening along U.S. 290, from an existing four-lane rural section to a five-lane urban section. CivilTech was responsible for performing the hydrologic and hydraulic studies, storm sewer design, and detention basin design. CivilTech prepared plans, specifications, and estimates (PS&E) sheets for the proposed drainage systems.

CivilTech Engineering, Inc. was contracted by the City of Houston to prepare construction plans for the replacement of approximately 13,500 linear feet of water lines in the Haden Terrace Subdivision - Sections 1 & 2, Southwood Subdivision, and the Sutton Place Subdivision. The project service area includes 15 residential blocks located inside Loop 610 and south of Houston's Central Business District. CivilTech provided preliminary and final design services and construction phase services. Additional services included surveying, geotechnical engineering, traffic control, construction sequencing, and tree protection services. Construction documents were prepared in accordance with the engineering design criteria, standards and specifications from the City of Houston's Department of Public Works & Engineering.

The City of Houston Bikeway Project encompassed nearly 350 miles of bikeways interconnecting bike trails along the major bayous with on-street bike lanes to provide bicycle commuters access to major business districts in the Houston metropolitan area. CivilTech Engineering, Inc. was contracted by the City of Houston and the Texas Department of Transportation to perform the detailed hydraulic and mitigation analysis for the new bike trails and bikeway bridges for the 18 funded bikeway projects. CivilTech developed the hydraulic and mitigation analysis procedures and methodology for the bikeway projects. The hydraulic and mitigation analysis is based on standard modeling guidelines established in consultation with the Harris County Flood Control District and the Texas Department of Transportation. A hydraulic analysis is being performed for over 100 new bikeway bridges or existing roadway bridges. The U.S. Army Corps of Engineers HEC-2 "Water Surface Profiles" computer program is being used for the hydraulic analysis. Project deliverables include hydraulic and mitigation analysis, hydraulic study reports, hydraulic data sheets, and bridge scour analysis and worksheets. TxDOT plan preparation was used for the hydraulic data sheets.
