Willow Trace

/

Willow Trace Harris County,TX The Willow Trace development covers 134 acres of land on Boudreaux Road in the northern portion of Harris County. The storm water drainage portion of the Willow Trace project involved the design of a three-basin storm water detention system, a pump installation to empty the lower (deeper) portion of the detention system, a 1,200-foot long discharge culvert, and improvements to a 3,400-foot segment of Harris County Flood Control District (HCFCD) Channel M114-00-00, a tributary to Willow Creek. RG Miller | DCCM used the HEC-RAS and HEC-HMS programs to complete hydraulic computations for Ditch M114-00-00 and the detention outfall system, as well as hydrologic routing operations through the detention system. Close coordination with the Harris County Public Infrastructure Department and Harris County Flood Control District was necessary to develop the final design of improvements to Channel M114-00-00, which called for concrete side slopes and an earthen bottom through most of the improved segment of the channel. A fully concrete-lined channel with multiple drop structures was required in the lower section of the channel to accommodate significant drops in natural ground elevation. RG Miller | DCCM prepared construction documents for the detention facility, pump installation, outfall pipe, and channel improvements. RGME also provided construction phase services for the project, including cost estimates, advertising, bidding, and direct oversight of the actual construction of the detention facilities and outfall drainage system.  

Freeport Street, Phase I

/

Freeport Street, Phase I Freeport,TX Reconstruction of Freeport Street from Woodforest to Uvalde including additional storm sewer/upgrading of storm sewers to alleviate occurrence of 1% (100-yr.) flooding in the neighborhood area. Project work also included the rework of numerous HCFCD Channels and Street Culvert Crossings to also convey the various storm events more efficiently. Included in the Project was the replacement of existing 2 lane concrete paving with new 2-lane concrete paving from Woodforest to Uvalde. Project was completed on time for a construction cost of $3,200,894.35  

Centennial Park, Phase II and Trail Expansion

/

Centennial Park, Phase II and Trail Expansion Pearland,TX This project involves the civil work of a 100 space parking lot, waterline, wastewater line, drainage and detention necessary for the existing Centennial Park in the City of Pearland to expand to include two new softball fields and restrooms. The Trail Expansion work will involve a mid-block pedestrian crossing on Veterans Drive. Project is currently under design with an Opinion of Probable Construction cost estimate of $350,000  

Houston Heights Neighborhood Street Reconstruction

Houston Heights Neighborhood Street Reconstruction Houston,TX This project involves the reconstruction of over 12,000 linear feet of city streets bounded by White Oak Bayou on the north, Studemont Street on the east, Washington Avenue on the south and Harvard Street on the west. Several waterlines and a full upgrade to the wastewater system are also included is the project.  

New Fire Burn Training Tower

/

New Fire Burn Training Tower League City,TX This project involved the civil work necessary to prepare the existing City of League City Fire Training site to receive a new Burn Training Tower. The work involved the removal of an existing car burn facility, new driveway access to Training Tower, drainage and parking lot.  

Birnamwood Drive

/

Birnamwood Drive Harris County,TX RG Miller | DCCM was retained to plan and design flow monitoring and stormwater sampling facilities to monitor the hydraulic and pollutant removal performance of the first low impact development (LID) roadway constructed in Harris County. The roadway is located in the Spring Creek watershed and features a depressed center median with a bioswale and a biorention cell for stormwater quality treatment. RG Miller | DCCM developed a detailed monitoring plan and quality assurance project plan along with an equipment installation design package. RG Miller | DCCM oversaw the installation of equipment, which included three stormwater samplers and four flow monitoring locations. Stormwater sampling activities began in June 2014 and sampling will be conducted for two or three years. After sampling 24 storm events, RG Miller | DCCM will conduct a statistical analysis of the flow and pollutant monitoring results and will prepare a final report.  

Freeport Street, Phase II

/

Freeport Street, Phase II Freeport,TX Reconstruction of Freeport Street from IH 10 to Holly Park from an existing 2-lane asphalt pavement with open ditch/small lateral culvert system to 2-lane with continuous left turn lane, concrete curb and gutter and storm sewer system. Storm sewer system included three offsite systems, a new HCFCD concrete low flow channel, and upgrading numerous HCFCD channel crossings all to alleviate occurrence of 1% (100-yr.) flooding in the neighborhood area.  

Reclaimed Water System Feasibility Study (Dowdell)

/

Reclaimed Water System Feasibility Study (Dowdell) Klein,TX RG Miller | DCCM  prepared a detailed feasibility study for the implementation of reclaimed water system serving 30 water demand sites.  The study outlined planning, design, and implementation regulatory requirements for the use of Type I reclaimed water under Title 30, Chapter 210 of Texas Administrative Code.  The project identified over 30 potential demand sites for reclaimed water including both irrigation areas and amenity pond make up water. Treatment technologies were evaluated and implementation costs were estimated.  Total capital costs were estimated to be $10.8 million.  Total avoided water purchase costs were estimated to be 1.8 billion gallons from 2015 to 2044.  The avoided water purchase costs were estimated to be about $14.8 million over that same time horizon.  Total expenditures, with interest payments included, were estimated to be $12.1 million; yielding a savings of $2.7 million.  If “alternative water” incentives offered by the regional water authority were included, total savings increased to $4.4 million over the planning time horizon.  

Wetlands and Stream Mitigation Bank Feasibility Study (Fort Bend County)

/

Wetlands and Stream Mitigation Bank Feasibility Study (Fort Bend County) Fort Bend County,TX RG Miller | DCCM prepared a feasibility study to determine if the development of a mitigation bank should be pursued, alone or in concert with a partner organization.  The study researched and determined the anticipated supply and demand of stream and wetland credits in the year 2040.  RG Miller | DCCM evaluated the supply and demand by watershed and recommended various possible locations for a mitigation bank.  Private land owners in the target watershed were approached to determine if there was interest in pursuing a joint or collaborative facility.  RG Miller | DCCM interviewed key managers and elected officials at the County to identify policy issues surrounding the establishment of a mitigation bank.  RG Miller | DCCM prepared detailed implementation cost estimates and revenue projections.  RG Miller | DCCM evaluated options using a comparison of calculated net present values.  

Wirt Road

/

Wirt Road Houston,TX This project consisted of 4,850 linear feet of Neighborhood Street Reconstruction (NSR) and 3,310 linear feet of major thoroughfare (Wirt Road) reconstruction. The NSR consisted of the reconstruction of asphalt open ditch to concrete curb and gutter with sidewalks. The neighborhood NSR was converted to underground storm sewer and as this is at the upper limit of the Wirt Road Storm System, a smaller parallel system was placed on Wirt and then interconnected downstream to convey the flows along Wirt.
