This Federal project for Brays Bayou included 3.2 miles of channel improvements, three ood detention basins, and 6.8 miles of stream diversion.

CivilTech was responsible for the investigations, procedures, and analyses to conduct the economic analyses that comprise the GRR for the development of an Alternative to the Diversion Element for Brays Bayou. The scope included the economics analysis for both Without Project Conditions and With Project Conditions under proposed structural and nonstructural ood damage reduction plans for the alternative to the diversion element. The study was conducted in accordance with the six step process outlined in the Economic and Environmental Principles and Guidelines for Water and Relation Land Resources Implementation Studies to meet the federal objective and contribute to National Economic Development (NED) consistent with protecting the Nation’s environment, pursuant to national environmental statutes, applicable executive orders, and other Federal planning requirements.

Brays Bayou watershed encompasses 128 square miles. The watershed is 95 percent developed with residential, commercial, industrial and public land uses. The Texas Medical Center, one the largest medical research complexes in the world, is located along Brays Bayou and has been at risk to historical ood damages. The economic study included a structure inventory of over 40,000 structures along 22 planning reaches. Sampling was performed to validate the use of secondary data for the improvement values provided by the Harris County Appraisal District. USACE HEC-FDA modeling software was used to perform the economic calculations. Risk and uncertainty was incorporated into the hydrologic, hydraulic, and economic relationships in the HEC-FDA model. The Single Occurrence 1% AEP Damage exceeded $2.1 billion with Average Annual Equivalent (AAE) Damages exceeded $90 million for Without Project Conditions. The NED Plan and Locally Preferred Plan (LPP) included channel modi cations and regional detention basins that would provide ood protection to over 10,900 structures. The LPP reduced AAE damages by almost $70 million whereby the net bene ts exceed the project costs.

CivilTech performed the risk-based analysis using the HEC-FDA modeling program. ArcView GIS was used to manage the physical characteristics of the watershed and the structure inventory along the study reaches. ESRI GIS products were used to describe the physical characteristics for the watershed and provide the structure inventory inputs for the HEC-FDA models.

GIS served as the key analytical tool for hydraulic/hydrologic modeling, eld data acquisition, and economic analysis of best use alternatives. The study procedures and methodology were in accordance with USACE’s Planning Study Guidelines for Civil Works and applicable engineering regulation and manuals. The economic feasibility was determined on the basis that the project bene ts exceed the project cost (B/C>1).

COMPLETION CONTRACT Gregory DiCioccio, PE, Harris County ROLE Prime % 100 LOCATION Houston, TX 2011 $150,000 CONTACT DATE COSTS Flood Control, 713.684.4000 At the request of the USACE Galveston District and Harris County Flood Control District (HCFCD), CivilTech was contracted to review and provide guidance for the economic analysis associated with a General Reevaluation Study for White Oak Bayou, HCFC Unit No. E100-00-00. The White Oak Bayou watershed encompasses 110 square miles in northwest Harris County. CivilTech performed the economic reevaluation in accordance with the federal objective of National Economic Development (NED) for ood damage reduction studies. The economic reevaluation included an assessment of the ood damage potential in the watershed and determined the ood reduction bene ts associated with the proposed alternative plans. CivilTech prepared the structure inventory for over 25,000 residential/nonresidential structures for the HEC-FDA model. This included Marshall and Swift cost estimates for over 300 properties, including single-family residential, apartments, condominiums, town homes, commercial properties, and public properties (churches, schools and universities). These served to validate the use of Harris County Appraisal District property data as proxy value for depreciated replacement cost. Other damage categories included vehicles, road, utilities, and post-disaster costs. The study procedures and methodology were in accordance with US Army Corps of Engineers’ Planning Study Guidelines for Civil Works and applicable Engineering Regulations and Manuals. Speci cally, NED Bene t Evaluation Procedures used in this project conformed to ER 1105-2-100 for Urban Flood Damage. CivilTech performed the risk-based analysis using the HEC-FDA modeling program. This included the Monte Carlo simulation to sample the interaction among hydrologic, hydraulic and economics. Several alternative plans and component evaluations were made using HEC-FDA. A socio-economic impact analysis was also performed to evaluate the NED objectives. The Hydrology portion of this project was developed using HEC-HMS, and HEC-RAS was used to develop ood elevations. A discharge frequency analysis was performed on the gauges in the watershed. The HEC-HMS model was calibrated to these gauges. ESRI GIS products were used to describe the physical characteristics of the watershed and provide the structure inventory inputs for the FDA models. GIS served as a key analytical tool and the primary spatial database platform for eld data acquisition, hydraulic/hydrologic modeling, and economic analyses of best use alternatives. For the recommended plan that best meets NED objectives, construction costs were estimated at $200 million. The ArcGIS suite was also used to manage the physical characteristics of the watershed and structure inventory along the study reaches employing the use of high resolution LiDAR data and 2-foot contours.
