Engineer for the Calabria Office and Retail Development, which is part of the 26-acre Uplands Village development that provides over 30,000 SF of retail and office space. The site preserved large oaks and incorporates limestone rock walls and tree wells to blend into the landscape and courtyard area. This site is located in the Contributing Zone of the Edwards Aquifer, an environmentally sensitive area that is strictly regulated by both the State of Texas and the ordinances of the Village of Bee Cave. For this reason, the design included a low impact site with only a 58.6% impervious cover. A reirrigation system was designed to provide a high water quality treatment.
We were responsible for designing this campus located on Austin Community College's (ACC) Round Rock location. We developed 10 new portable classroom buildings, along with large walkways for pedestrians, utilities, bus drop-off, accessible routes, and connectivity with surrounding areas.The site/civil plans included designing a pedestrian traffic control plan to safely accommodate ACC students while construction was taking place. This campus is considered a temporary early college facility until a more permanent facility can be planned, budgeted, and constructed. The project was on an extremely tight timeframe as the planning, design, permitting, and construction duration was completed in less than six months.
The Capital Metro North Operations and Maintenance Facility is a 110,000 square foot bus and van transit operations center. The site is located on an 18-acre site just north of Hwy. 183 and east of Burnet Road (F.M. 1325). This fast-paced project required programming, design, permitting and construction to be completed in less than 20 months. Several major elements of the project included demolition of existing industrial facilities, solving the public water system's limitations in the area, permitting the site without on-site water quality and detention facilities, re-routing drainage conveyance, and off-site roadway improvements. We were the on-site civil engineer for the project and designed the grading, drainage, parking and drive, and the water and wastewater facilities. During the programming phase, we investigated the potential of using existing off-site water quality and storm water detention facilities. Because we were successful in documenting that the detention and water quality ponds already met City of Austin requirements, we did not have to build any new water quality and storm water detention facilities. This ended up being critical to facilitate the development needs of Capital Metro on the limited site. We also led a detailed study of the City's water distribution system to solve poor fire flow capabilities in the area. Upon systematically breaking down the water distribution system for analysis, we were successful in finding a broken valve on the major transmission main feeding this pressure zone. With the replacement of the broken valve, on-site fire pumps were not required and existing fire pumps and tank storage (supporting existing buildings) could be removed, providing additional use of the area and a tremendous saving on the construction cost. We designed all on-site water, wastewater, storm drainage, and parking and drive facilities and permitted the site through the City of Austin within the Capital Metro Transportation Authority (CMTA) required time frame.

The City of Austin owns and maintains at least 63 high hazard dam structures across the City. State and City dam safety criteria require these high hazard dams to be able to safely pass the Probable Maximum Flood (PMF) without failing. Our project team performed preliminary design assessments of the 63 dams to determine whether or not the dams were capable of safely passing the PMF, and if not, to perform preliminary designs of mitigation efforts to allow the dams to safely pass the PMF. We provided the following services: Assisted in developing the hydrologic models for the 63 dams as part of the preliminary design services Calculated times of concentration for contributing runoff and developed HEC HMS models. Delineated drainage boundaries for each of the 63 structures based on available information and site visits Performed “peer review” of the proposed FNI methodologies for preliminary risk assessment from a theoretical breach and the overall structure ranking Provided input to the methodologies including technical publications on calculating breach width and breach side slopes, flowchart diagram to depict various evaluation steps, and a “sensitivity analysis” for dam breach velocity related to attenuation length Prepared memorandums summarizing the results of the peer review Under final design services, assisted the project team with developing hydrologic and hydraulic models for Pond Dams 26, 220, 267, 337, 581, and 726
SC Robertson Dam (Lake Limestone) and DeCordova Bend Dam (Lake Granbury) Breach Analyses and Inundation Mappings The Brazos River Authority (BRA) owns, operates and maintains a series of dams along the Brazos River. The dams have high-hazard classifications because of the consequences of dam failures, and because their sizes and hazard ratings are subject to State Dam Safety criteria. One of the dam safety criteria is that high-hazard dams must have written Emergency Action Plans with detailed supplemental breach inundation mappings. The BRA hired a preeminent hydrologic & hydraulic engineering firm to prepare the complicated breach analyses (using HEC-RAS hydraulic modeling) and detailed breach flood inundation mappings for S.C. Robertson Dam (Lake Limestone) and DeCordova Bend Dam (Lake Granbury) for “sunny-day” breach failure conditions and for Probable Maximum Flood (PMF) design flood conditions. S.C. Robertson Dam has a 8,130 foot-long embankment section with a maximum fill height of 60 feet, a concrete gravity spillway with 5 radial gates and a stilling basin. DeCordova Bend Dam has a 1,400 foot-long compacted fill embankment section with a maximum fill height of 63 feet, a concrete Ambursen-type spillway with 16 radial gates and a stilling basin. Breach analyses and breach flood inundation mappings were performed using HEC-RAS hydraulic program. Our firm calculated the breach parameters for both dams, the embankment sections, the gated spillway sections, the “sunny-day,” and for PMF design flood hydraulic conditions. We performed data research of the configurations of the two dams, including reviews of the construction as-built drawings and performed site visits to confirm field conditions and to confirm the locations and types of reasonable breach scenarios.
Scenic Brook Flood Control Project, Hydrologic Modeling & Dam Hazard Analysis The Scenic Brook neighborhood is located on the Scenic Brook Tributary to Williamson Creek in the City of Austin. The neighborhood has been plagued by frequent local flooding. The City hired a team to develop mitigation measures. As part of the solution, the team identified a stormwater detention pond up gradient from South Brook Drive to reduce peak flowrates entering the neighborhood. We provided the following: Developed the SCS TR-20 model for the existing and future condition for the 2-, 5-, 10-, 25-, and 100-year storms Coordinated with TCEQ staff on dam safety requirements. Coordinated with staff in adjusting detention pond outlet structures to meet flood control objectives and TCEQ requirements. The detention pond consisted of a concrete retaining wall embankment, and is approximately 16’ high with a flood storage volume of about 22 acre-feet. Developed dam safety analysis using the Probable Maximum Flood (PMF) storm event Prepared engineering report documenting the project approach and conclusions.

Dripping Springs Ranch Park Event Center is located in a 95-acre City-owned park. The proposed project consists of an approximate 150,000 SF arena with associated parking, utility improvements and water quality pond. Primitive camping, hiking trails and a horse trail are included in the park amenities. The site is located in the environmentally-sensitive Little Barton Creek Watershed and is entirely in the Edwards Aquifer contributing zone. Portions of the site are within the FEMA 100-year floodplain. The earthwork will require cuts and fills of less than 6 feet. Most of the existing trees on the site are proposed to be saved. Retaining walls with the maximum height of 5 feet are proposed at two sides of the parking area to save the trees. On site excavated boulders are proposed to be used for the construction of the retaining walls. Water service to the proposed event center will be provided by the Dripping Springs Water Supply Corporation. The site plan also includes extension of water service to RV sites. Wastewater service will be extended to the site from the City's existing service main. A 2,500-gallon tank dump station is proposed for the RV vehicles and trailers. Waste from the dump station will conveyed to the event center's discharge line.
Doucet worked with the City of Sunset Valley to provide conceptual plans and design for the construction of an extended portion of Ernest Robles Way (ERW) between U.S. 290 and Jones Road. The project included excavation of substandard subgrade and base materials and reconstruction of curbs and gutters and repaving, plus installation of decorative medians for separating traffic, and creating unobstructed turning lanes for school bus traffic and commercial vehicles. The project also included injection grouting and repair of failed pavement areas; improving turning radii at U.S. 290 and Jones Road intersections; construction of raised boulevard section toward each end of roadway; placement of a 2-inch hot mix asphalt overlay on ERW from Jones Road to Hwy. 290 and pavement markings on the entire length of ERW from Brodie to Hwy. 290.

The main purpose of this project was to develop digital geo-referenced hydrologic and hydraulic models and floodplain maps for the Bull and West Bull Creek watersheds for both existing and fully-developed land-use conditions. Our responsibility for this project involved developing hydraulic data and floodplain mapping for selected tributaries of Bull Creek. We developed: Fully-annotated HEC-RAS models with all supportive GIS files such as cross-sections and GIS geodatabase for both existing and fully-developed land-use conditions Digital hydraulic data including tables, methodology descriptions and exhibits for Existing and Fully-Developed Land-use Conditions to incorporate into the Hydraulic Technical Support Data Notebooks (TSDN), Water surface elevation profiles at similar vertical and horizontal scale as the profiles in the effective FIS report for selected FEMA flood frequencies using RAS-PLOT for the detailed study tributaries only, Floodplain mapping Digital copies of the floodplains and BFEs for the detailed study tributaries for both existing and fully-developed land-use conditions
Over 175 homes located in the Crystal Brook neighborhood were threatened by frequent flooding due to floor elevations below the 100-year storm water surface elevations. We provided the following improvements: 16,600 LF of storm sewer lines (ranging from 18” RCP to 12’ x 7’ concrete box) 7,000 LF of channel improvements (ranging from 6’ wide to 100’ wide bottom) 5,700 ft. flood barrier system 2,000 LFof creek bank stabilization and restoration
Los Indios Culvert Upgrade and Channel Improvements The Los Indios subdivision and Los Indios Trail are located in northwest Austin. The Los Indios Trail roadway was overtopped by Rattan Creek during the 10-year and greater return period storm events putting seven (7) homes in the vicinity of Los Indios Trail at risk of flooding in the 100-year storm event. Using on-the-ground topographic survey, we developed alternatives to mitigate the culvert and local flooding problems and prepared construction plans for the proposed improvements.
We performed a hydrologic and hydraulic study of the existing storm drain network in the lower Fort Branch Oak Lawn Subdivision area bounded by Springdale, Heflin, Webberville, and Ribecke roads. This area was identified as having localized flooding problems through the Fort Branch Watershed Integrated Solutions Study. As a result, new storm drain systems were designed to supplement the existing systems. The final design encompassed approximately 5,500 LF of storm drain pipe and 2,000 LF of water main.
