In 2018, the City of Batesville requested Mendrop Engineering Resources (MER) help the City develop a plan of action to help locate potential infiltration and inflow sources into the sanitary sewer collection system throughout the entire city-wide system. Upon completion of the survey, MER helped develop a plan to rehabilitate the identified problems.

In 2019, the City of Batesville bonded $8 million for several projects, including sanity sewer improvements along Highway 35 and Sand Creek. Located on the north side of Batesville, the project will upgrade existing infrastructure as well as provide critical infrastructure for this rapidly developing area of the City of Batesville and Panola County.

The Mississippi Department of Transportation (MDOT) proposed a plan to widen U.S. Highway 11 between Cayten Street and Lakeshore Drive from a 3-lane section to a 4-lane divided boulevard through Picayune in Pearl River County, MS. Mendrop Engineering Services, LLC (Mendrop) was retained by MDOT to perform a hydrologic and hydraulic analysis of the proposed storm drainage system for the roadway widening. The study included the development of a hydraulic storm sewer model of the storm drainage system as currently designed in order to evaluate and document the hydraulics of the system.

Mendrop Engineering Resources, LLC was selected by the Mississippi Department of Transportation (MDOT) to prepare conceptual, preliminary, and final bridge hydraulic recommendations and bridge plans for Jourdan River, Bayou Talla, and a tributary of Bayou Talla on a proposed project to bypass Kiln, MS by relocating a portion of State Route 43/603. Initial conceptual bridge recommendations for the bridges over Jourdan River and Bayou Talla were originally prepared by Mendrop during the Environmental Planning Phase of this project.

Mendrop Engineering Resources, LLC (MER) was selected by the Mississippi Department of Transportation (MDOT) to provide hydraulic recommendations and bridge plans for the hydraulic crossings of Mattie Creek (Bridge #33.2) and Nelson Creek (Bridge #33.6) on State Route 310 (SR 310). In a separate contract, MER was selected to develop Phase “A” Final Right-of-Way plans for the bridge replacements (Bridges # 33.2 and #33.63) on SR 310 in Panola County.

Mendrop Engineering Resources, LLC was selected by the Mississippi Department of Transportation to evaluate the potential for scour and develop a plan of action at the bridge site on U.S. Interstate Highway 55 (I-55) Bridge #266.8A & B over Hickahala Creek in Tate County. The bridge scour evaluation study was performed in four phases, including hydrologic, hydraulic, and scour analysis and a geotechnical and structural assessment. Burns Cooley Dennis, Inc. was subcontracted to perform subsurface exploration at the site, while Amec Foster Wheeler (AFW) was subcontracted to perform the structural assessment. Mendrop then utilized the data and analysis to provide MDOT with a recommended plan of action.

The Homochitto River has undergone significant channel degradation, extensive meandering, and lateral movement since the 1940s, and SR 33 bridges at this location have collapsed three times.

Canadian National Railroad (CN) contracted Mendrop to evaluate the hydrologic conditions and hydraulic characteristics of existing bridges and culverts in order to provide guidance for replacement.

In 2014, Mendrop began defining the scope of work for a new water well project to improve water capacities for the City of Batesville. Based on the existing water system configuration, a suitable location for the new water well was determined to be just east of Interstate 55 and approximately 0.8 miles south of State Highway 6.

Alcorn State University (ASU) chose Mendrop to address issues in their water system and help bring them into compliance with the Ground Water Rule. Mendrop worked with ASU and the MS State Department of Health (MSDH) to create a reasonable budget and schedule to repair and repainting of two 100,000-gallon elevated water tanks.
