HYDRAULICS AND HYDROLOGY

 

.     TXDOT - Hempstead Highway- The design for this project consisted of increasing

      capacity from four lanes to six  lanes including replacement of railroad bridges;

            reconstruction of existing pavement; revision of intersections and signals; and upgrade of

            drainage outfall and storm sewer system.  This project consisted of numerous drainage

            studies to determine alternatives to drain Hempstead and I-10, as well as solve I-10

            flooding problems.

.     HCFCD - Clear Creek Regional Drainage Plan-Phase I- This project involved  a

      comprehensive stormwater management plan and environmental assessment for the Clear

            Creek Watershed encompassing approximately 260 square miles of drainage area and 50

            miles of network channels.  The project included hydrologic analysis of all sub-

            watersheds in the basin, land use analysis, development of runoff coefficients and storm

            frequency and rainfall analysis. This information was used to develop new flood plain

            mapping, evaluate channel rectification needs, analyze detention requirements and

            investigate alternative design solutions for future  improvements.

.     HCFCD Clear Creek Regional Drainage Plan-Phase II- This project involves unifying the design criteria of four counties, seventeen cities, five drainage districts, and twenty-seven utility districts.  Stormwater technical, legal, financial, and environmental issues will be addressed in the development of a management plan.  The project includes collecting, evaluating, and updating all previous and ongoing major studies and plans which have an effect on formulating an overall master plan.  The Corps of Engineer's Clear Creek Project, the League City Drainage Master Plan, the Clear Creek Drainage District's Mary's, Chigger and Cowarts Creeks and other planning projects are being incorporated into the master plan. The intent is to establish policy and procedures for all of these agencies to cooperate in implementation and enforcement of a watershed management program.  This phase also included the analysis of flood control pure alternatives such as no-action, non-structural, channelization, detention, as well as a combination plan. A plan consisting of regional detention sites and channel improvements of main channel and tributaries was devised to significantly reduce flooding in the Clear Creek Watershed.  The plan cost is approximately $500,000,000. Fifty percent of the project is funded by a grant from the Texas Water Development Board, and fifty percent is funded by the Harris County Flood Control District.

.     HCTRA South Belt Master Drainage Study- The South Belt Master Drainage Study from FM 521 to Beamer Road included the evaluation of the watershed drainage impact of the construction of the South Belt mainlanes and frontage roads.  Most of the roadway is in the 100 year floodplain.  DEC has determined the loss of storage and conveyance, impact of development, bridge crossings and equalizer culverts.  Also, DEC has reported on mitigation alternatives and possible detention sites.

.     HCFCD Upper Greens Bayou Update/Regional Planning- This project includes an update of HEC l and HEC 2 models to 1995 conditions, preparation of land use/detention scenarios as instructed by HCFCD.

.     HCFCD Cutten Road, Project Engineer- This project includes modeling of the connecting structure between Greens Bayou and Cutten Road. Regional detention modeling includes HEC-2 model and ICPR (variable tailwater) to properly size the connecting structure.  Preliminary construction drawings will be provided to HCFCD for the next step, which is the final design.

.     HCFCDWillow Waterhole, Project Engineer- This project consisted of evaluating flooding problems along Willow Waterhole Bayou from South Post Oak to Hillcroft Drive and making cost effective drainage recommendations.  Findings indicated that current channel protection was the 10-year storm, plus the majority of the houses were above the 100-year level.  A cost-effective recommendation was a maintenance program to desilt channel bottom by three feet, plus repair all slope failures.

.     City of Sugarland - Sugar Land Municipal Airport- This project includes fiveconstruction

            projects and one planning project.  The construction projects include:  lighted  sign

            system and electrical repairs; joint seal and crack repairs; runway and taxiway pavement

            markings; PPAPI; and segmented circle with lighted wind cone. The planning project

            was a drainage development plan.

.     Clear Creek Regional Drainage Plan-Phase II, Hydrologist- This project involves

unifying the design criteria of four counties, seventeen cities, five drainage districts, and

twenty-seven utility districts. Stormwater technical, legal, financial, and environmental

issues will be addressed in the development of a management plan. The project includes

collecting, evaluating, and updating all previous and ongoing major studies and plans

which have an effect on formulating an overall master plan.  The Corps of Engineer's

Clear Creek Project, the League City Drainage Master plan, the Clear Creek Drainage

District's Mary's,  Chigger and Cowarts Creeks and other planning projects are being

incorporated into the master plan.  The intent is to establish policy and procedures for all

of these agencies to cooperate in implementation and enforcement of a watershed

management program. This phase also included the analysis of flood control pure

alternatives such as no-action, non-structural, channelization, detention, as well as a

combination plan.  A plan consisting of regional detention sites and channel

improvements of main channel and tributaries was devised to significantly reduce

flooding in the Clear Creek Watershed.  The plan cost is approximately $500,000,000.

Fifty percent of the project is funded by a grant from the Texas Water Development

Board, and fifty percent is funded by Harris County Flood Control District.

.     Sunset Meadows Subdivision Flood Control, Hydrologist- This project consisted of

removing the subject property from the 100-year floodplain of Mary's Creek By-Pass.

Updating of HEC-2 backwater modeling was needed to support the claim that flood

waters were contained within By-Pass  channel banks.  Preparation of a LOMR package,

as well as extensive coordination with FEMA and the City of Pearland, was needed to

modify the flood hazard zone and remove property from the regulatory 100-year

floodplain.

.     Riverwalk Subdivision Flood Control, Hydrologist- This project consisted of removing

the subject property from the 100-year floodplain of Mary's Creek By-Pass.  Updating of

HEC-2 backwater modeling was needed to support the claim that floodwaters were

contained within By-Pass channel banks.  Preparation of a LOMR package, as well as

extensive coordination with FEMA and City of Pearland, was needed to modify the flood

hazard zone and remove property from the regulatory 100-year flood  plain.

.     La Casita Dam- This project involved the evaluation of spillway capacity of existing dam

and recommendations on improvements.

.     TECO Hazardous Waste Management Facility Drainage Study, Project Engineer- DEC

performed a drainage study at TECO Hazardous Waste Management facility in Nueces

County, Texas in order to develop a drainage plan for 400 acres of which 163 acres are

active. Development impacts were evaluated and a mitigation plan was proposed,

consisting of channel rectification.  Hydrologic (HEC-1) and Hydraulic (HEC-2) models

were used to predict impacts and prepare improvements.  The study was conducted to

comply with Texas Water Commission permit application requirements for industrial and

hazardous waste facilities.
