Dallas Floodway 277K Levee Raise and Delta Pump Station

In 2020, MSMM Engineering was tasked by the United States Army Corps of Engineers (USACE) Ft. Worth District to design various recreational, roadway, and bridge features for a public recreational park in South Dallas. This project involved the planning and design of various recreational components on a former golf course in South Dallas. The trail system and bridge features were designed for the United States Army Corps of Engineers (USACE) Ft. Worth District in support of the City of Dallas. The Dallas Floodway extension project consisted of various access routes, walking/vehicular trails, bridges, boardwalks, and platforms. The project provided recreational access to a chain of wetlands designed to provide unimpeded overflow for floodwater along the west side of the Trinity River from the Dallas Floodway to Loop 122. The project continues an overall master planning effort to provide recreational access across Dallas with uninterrupted access. This project provided another 12-miles of multi-use trails, additional parking lots at major trail connection points, three additional bridges, including one larger bridge across the Trinity River, an elevated boardwalk trail for access across a low-lying marshy area, and new birdwatching platforms in the previously created wetlands. The design team also added public safety features including culverting for water distribution, locked gates, and pipe rail fences for the City of Dallas to manage public access, site lighting in the added parking lots, and site signage at the access points for time periods where the recreational areas are flooded, and public access is restricted. Benches were also added at scenic overlooks, wildflower areas and for views of the wetlands. MSMM provided full engineering services to the USACE, including schematic design, preliminary design, and final design. The scope of work included the development of plans and specifications for three (3) bridge crossings, one over the Elam Creek (60 feet), one over the chain of wetlands, and a larger crossing over the Trinity River (150 feet). Additionally, the design package consists of over 10 miles of 12-ft wide multi-use roadway (trail) for vehicular/walking trail access, the restoration of parking lots at trail heads, the inclusion of pipe rail fences and gates to prevent after-hour access, and the design of bird watching platforms over the wetlands. MSMM performed H&H modeling of the Trinity River to help aid in the bridge design process. All roadway/bridges consist of a single lane and were designed to contain the load of school buses/emergency vehicles. Additionally, our team performed detailed cost estimating utilizing MCACES. We also provided design and project schedules utilizing the Primavera suite of scheduling services.

East Baton Rouge Parish North Landfill Leachate Pond Abandonment

Through a Federal program to fund Environmental Infrastructure programs within local municipalities, MSMM representing the USACE New Orleans District, is working with the East Baton Rouge Parish Government (non-Federal sponsor) on a program to eliminate the onsite lagoon treatment and discharge in favor of a new forcemain and pump station modifications that ties into the city-parish sanitary sewer treatment facilities. This program is being undertaken due to anticipated increases in stringency of discharge limitations into Baton Rouge Bayou; it will eliminate a discharge permit through the LDEQ; and takes advantage of the newly constructed Zachary Area Transmission Network Improvements Project. MSMM was responsible for providing 100% bid ready plans and specifications (in USACE format) for closure and abandonment of the three surface treatment ponds. Design documents addressed methods to drain the ponds; removal and disposal of the existing sewage sludge; removal of the existing levees surrounding the ponds; removal of the HDPE liners; removal of existing treatment equipment including piping, concrete structures, and UV System; and fill and grading of the approximate 6-acre area to return it to the appearance of natural land. Additional services performed by MSMM included survey, geotech, sludge sampling for analysis, MCACES cost estimate, coordination with East Baton Rouge Parish and the landfill operators. Continuing tasks upon completion of the pump station and forcemain construction will be to assist the USACE with bidding and construction services, EA and coordination with the LA Department of Environmental Quality (LDEQ) for closure of the treatment facilities.

Farmsite Road Canal Crossing Culvert

MSMM performed civil and structural design (including schematic, preliminary, and final design), hydraulic modeling, survey services, and construction management for the replacement of an undersized culvert at Farmsite Road and Green Avenue Canal in Violet, LA. The project wrapped up construction in October of 2020 and consists of a pre-cast arch culvert bridge system. MSMM developed a hydraulic analysis of the location including analysis of existing canal flows, existing culvert configuration flows, and optimum flow allowances to account for a large watershed event. Following the completion of the hydraulic analysis, MSMM provided updated information to FEMA for refinement of the project worksheet and used the hydraulic data to determine which Arch Culvert bridge system was best applicable to design. MSMM then designed the pre-cast Arch Culvert bridge replacement, which was approved by FEMA. The project was bid in the Winter of 2019 and MSMM continued to provide construction management and engineering during construction.

Golden Triangle Marsh Creation (PO-163)

The Golden Triangle Marsh Creation Project (PO-163) was a key project identified by MSMM staff when providing water resources planning for the MRGO Ecosystem Restoration Plan at the USACE New Orleans District. MSMM staff developed the conceptual project as a means to provide natural ecosystem restoration in front of the IHNC Surge Barrier, under the Multiple Lines of Defense strategy for hurricane risk reduction. While the MRGO plan failed to move forward because of the lack of a willing non-Federal sponsor, the Golden Triangle element was brought back as a stand-alone element when the New Orleans District was competing for RESTORE Act funding. Based on having prior knowledge of the project, MSMM was chosen to provide engineering design services for this project. The Golden Triangle marshes chosen for restoration are a highly fragmented intermediate to brackish marsh system that has crisscrossing pipeline corridors and multiple internal and lateral bayous. Upon receiving the job, MRGO staff started the process of field investigations by completing the following: side scan-sonar data identifying hard bottom substrate within Lake Borgne to provide available borrow sites, followed by soil borings at the restoration site and borrow pit location, as well as survey data and bathymetry data. Once field investigations were completed, MRGO started the process of identifying potential design acreage amounts, identifying bayous to be left open for traversing the site, and identifying areas of interest for recreational activities like fishing and hunting. Meeting with multiple user groups was key as all had a distinct interests/needs for the site, and the overall restoration goal of the project needed to be maintained. The restoration goal of the project was to restore and nourish approximately 4,000 acres of marsh. Design features consisted of perimeter dikes, vinyl sheet closure pile structures, and internal weirs. Through a collaborative design process with the engineering branch staff at MVN, the NGO community advocating for restoration of this site, the recreational user groups and the oil and gas companies that rely on this site, MSMM was able to identify the site configuration above as best meeting the design goals of the project. To date the project has not been constructed by USACE, but is being constructed under the RESTORE ACT program, for the Coastal Protection and Restoration Authority of Louisiana.

Granger Lake Management Office Building Design

The previous facilities for the Lake Management staff at Granger Lake have been in a state of disrepair for a number of years. MSMM Engineering was been tasked by the USACE Ft. Worth District to design new facilities for the Granger Lake management staff to utilize for operability of the lake. Granger Lake Management Office design package was completed before the end of the Federal fiscal year in 2019, and consisted of the development of a construction package for the remediation and demolition of the existing 5,890 SF lake management facility located at 3100 Granger Dam Road, Granger, TX, and the design of a new facility across Granger Dam Road from the existing facility. The new facility is one story and was designed for approximately 4,856 SF in gross area. The design package for the new facility includes site development, new construction inclusive of all required services (i.e. electrical/mechanical/ fire protection/life safety/civil/structural/architecture). Design activities also included the design of landscaping, new paving, paving repairs, and force protection. The new facility houses offices for lake management staff, and a conference room to accommodate up to 60 people with tables and chairs. Site lighting was designed, along with parking for visitors and staff. Additionally, the fencing design required for the government vehicle and equipment compound behind the new office, was designing and included with the construction documents. As mentioned above, MSMM completed all of the mechanical design for this facility. The mechanical design consisted of heating, ventilating, air conditioning, refrigeration, energy, piping and plumbing systems. Mechanical design for the facility complied with the following codes: International Mechanical Code (IMC), International Plumbing Code (IPC), National Fire Protection Association (NFPA), Sheet Metail and Air Conditioning Contractors National Association (SMACNA), American Society of Heating, Refrigerating and Air Conditioning (ASHRAE) and the Americans with Disabilities Act (ADA). For HVAC, the facility was designed to utilize a standard split system style direct expansion system with indoor air handling units and outdoor condensing units with one system dedicated to providing conditioned outside air to the space. The indoor units utilize electric heat strips for winter conditions. Generally, the building was designed to be conditioned by multiple direction expansion coil type air handing units with electric heat. For exhaust, the Men and Women restrooms, Janitor Room, and Lobby restroom exhaust system were all designed to discharge through a single roof penetration located near the restrooms. Sanitary sewer was designed so that sewer waste discharges to a single point located along the North end of the building. The following sanitary sewer fixtures were included with the design package: Two Compartment Sink (Break Room -1), Lavatories (Women, Men and Lobby Restrooms – 5), Flush Valve Water Closets ( Woman, Men and Lobby Restrooms – 6), Floor Drains (Women, Men and Lobby Restrooms – 4), Urinal – Flush Valve (Men Restroom), High/Low Drinking Fountain (Rear Lobby – 1), Service Sink (Janitor Closet -1), Condensate Discharge from AHU’s located above ceiling – 2, and discharge from the ice machine (break room – 1).
