Projects

Guided by a client-first approach, MAY Engineers delivers impactful projects that solve complex challenges in water resources and infrastructure. Our innovative designs and sustainable strategies are crafted to meet client needs while enhancing communities and protecting the environment.

LADOTD District 04 Bridge Hydraulic Desing and Scour Analysis

MAY performed hydrologic analysis for the nine bridges using the LADOTD Hydra1130 program using both the Natural Resources Conservation Services (NRCS) and the United States Geological Survey (USGS) methods for the 2-year, 5-year, 10-year, 25-year, 50-year ,100-year, and 500-year storm events. MAY initially delineated contributing drainage areas for each bridge, computed the drainage areas, used the USGS method for drainage areas greater than 2000 acres, and used the NRCS method for bridges with drainage areas less than 2,000 acres associated with the LADOTD Hydraulic Desing Manual.

LADOTD District 05 Bridge Hydraulic Desing and Scour Analysis

MAY performed hydrologic analysis for two bridges using the LADOTD Hydra1130 program using both the Natural Resources Conservation Services (NRCS) and the United States Geological Survey (USGS) methods for the 2-year, 5-year, 10-year, 25-year, 50-year ,100-year, and 500-year storm events. MAY initially delineated contributing drainage areas for each bridge, computed the drainage areas, used the USGS method for drainage areas greater than 2000 acres, and used the NRCS method for bridges with drainage areas less than 2,000 acres associated with the LADOTD Hydraulic Desing Manual.

City of Pine Bluff (AR) Watershed Planning and Environmental Assessment

MAY has led the developing a Watershed Plan and Environmental Assessment for the City of Pine Bluff, Arkansas as a subconsultant to the EJES|FTN JV. The purpose of the project is to meet the USDA-Natural Resources Conservation Service (NRCS) requirements for a Watershed Plan-Environmental Assessment (Plan-EA) or Environmental Impact Statement (EIS) pursuant to Public Law 83-566, the Watershed Protection and Flood Prevention Act. The project areas include the following watersheds:

Bayou Bartholomew Headwaters Watershed (HUC 080402050101)
Caney Creek-Caney Bayou Watershed (HUC 111102070605)
Caney Creek-Arkansas River Watershed (HUC 111102070604)
Plum Bayou-Arkansas River Watershed (HUC 111102070606)
Cousart Bayou Headwaters-Lake Alice Watershed (HUC 080402050201)
Imbeau Bayou Watershed (HUC 080402050103)
Nevins Creek Watershed (HUC 080402050102)
Upper Deep Bayou Watershed (HUC 080402050203)
Boggy Bayou-Bayou Bartholomew Watershed (HUC 80402050104)

Tasks for developing the Plan-EA include an amount of engineering/design to accurately define and evaluate alternatives proposed in the Plan-EA for technical feasibility, socioeconomics, benefits, and impacts. The JV developed Hydrology and Hydraulic models for the 9 HUC-12 watersheds using HEC-RAS 2D Version 6.4.1 spatially varied precipitation and infiltration options. Python-based GIS software to analyze existing stormwater infrastructure, identify areas with undersized systems that need upgrading, and model potential improvements and their impacts on the system. Proposed alternatives include upgrading undersized stormwater pipes and designing new or upgraded culverts to improve water flow, designing detention ponds to manage stormwater runoff, and pump stations to aid in stormwater management, especially in low-lying areas.

Stamps and Lewisville (AR) Watershed Planning and Environmental Assessment

MAY Engineers has led the developing a Watershed Plan and Environmental Assessment for the cities of Stamps and Lewisville, Arkansas. The purpose of the project is to meet the USDA-Natural Resources Conservation Service (NRCS) requirements for a Watershed Plan-Environmental Assessment (Plan-EA) or Environmental Impact Statement (EIS) pursuant to Public Law 83-566, the Watershed Protection and Flood Prevention Act. The project areas include the following watersheds:

Williamson County Detailed Flood Study and Mapping, Texas

MAY Engineers performed an independent review of more than 180 HEC-RAS models for the Willamson County Atlas 14 Floodplain Mapping Project for Brushy and Yegua Creek watershed extents. The project is part of the development of georeferenced hydrologic (HEC-HMS) and 1096 stream miles Zone A and Zone AE hydraulic (HEC-RAS) models for existing and fully developed land use conditions for selected storm frequencies based on NOAAA Atlas 14 rainfall data.
