Water Resources

McGill’s Water Resource team provides communities with solutions to their water resource challenges and assists them in adapting to and complying with regulatory drivers. With over three decades of experience across the southeastern United States, we provide programmatic and project support that includes all aspects of project delivery, including planning, stakeholder facilitation and public meetings, environmental permitting, preparation of plans and specifications, CADD and GIS production, cost estimating, grants management, bid services, and full construction administration.

Supported by our expert modelers and GIS capabilities, our engineers can address a broad range of projects from stormwater system design and BMP retrofits to watershed-wide flood management and water quality improvement master plans. We integrate a depth of knowledge in environmental planning, hydraulic system modeling, infrastructure design, and construction management to provide holistic water resources solutions to our clients.

case study

CLIENT: City of Asheville
PROJECT DESCRIPTION: McGill Associates served as program manager to oversee a major public infrastructure improvement project of the heavily-traveled Azalea Road area, a popular destination in East Asheville that encompasses a residential neighborhood, WNC Nature Center, playground and pool, City of Asheville recreation staff offices, and a large regional soccer complex. The project was funded by a combination of federal, state, and local dollars and provided multiple benefits in the areas of flood management, storm water management, transportation improvements, multi-modal transportation, and public utilities improvements. Innovative stormwater measures were implemented and wetlands protected throughout the site, including the introduction of a new roundabout that included a rain garden with a landscape design of a soccer ball. The rain garden receives stormwater from area road runoff in a high-traffic area and treats runoff and provides added offline storage before discharging into a bioretention garden in the adjacent parking lot below the roundabout.

Flood Management
The flood management component involved a comprehensive structural evaluation and hydrologic model of the former Lake Craig dam on the property in order to determine its feasibility to serve as a future mitigation measure to address downstream flood impact, particularly in Biltmore Village. The project included floodplain fill removal and bank restoration along the Swannanoa River. A series of three public input meetings took place to satisfy NEPA requirements, and McGill worked extensively with the City to promote public interest in the project through social media and on-site kiosks.
