University of MD Comcast Center and North Campus Development, College Park, MD

AMT was proud to win the ACEC/MW National Recognition Award for the University of Maryland Comcast Center in the 2003 ACEC Engineering Excellence Awards Competition. AMT provided planning, civil engineering design and construction administration services for the new sports arena, and supporting facilities, including athletic fields, maintenance yard, and parking garage. Approximately $22 million worth of new infrastructure was required including new access roads, new parking lots, road widenings and realignments, irrigation systems, storm drainage, and stormwater management facilities.

Roadways - AMT gave careful consideration to vehicular and pedestrian flow during conceptual design. A new 2000 LF access roadway was designed for the project. Over 9000 LF of existing roadways were realigned and widened. Over 5000 LF of shoulder and roadway improvements were provided at MD Rt. 193 including turn lanes, widening and bike lanes. Curb/gutter, sidewalks, and planting strips were designed, and AMT analyzed on-campus, off-site, and event parking.

Stormwater Management - A stormwater management/ watershed study was prepared for the entire northeast campus. A TR-20 based hydrologic report documented before and after development run-off rates. Construction documents were prepared for three pond retrofits. Two bioretention facilities were provided. Flow splitters were designed to divert the first flush of run-off to the bioretention facility. Underdrains were provided to ensure proper drainage through the facility. One new extended detention wetland marsh was also provided.

Environmental Design - A 100 year floodplain study was prepared to document affects of the project on the Paint Branch floodplain. A HEC-2 hydraulic study was prepared with a before and after development analysis to determine what, if any, increased 100-year floodplain elevations could be caused by the proposed development. A wetland delineation was prepared. Permits were obtained from ACOE and MDE for work in waterways and wetland impacts.

Storm Drainage/Utilities - Utilities were located, mapped and analyzed to determine adequacy. Coordination was provided to minimize impacts to existing electric, gas, steam and telecommunication lines. AMT prepared design for extension/relocation of 3,000 LF of 12 inch water. 1,500 LF of new water and sewer lines were designed. Over 7,500 LF of storm drain were designed for roadways, parking lots and plaza area infrastructure. The Rational Method was used to compute run-off rates, and pipes were sized based on Manning's open channel flow. Crossings with existing and proposed utilities were accounted for to ensure proper clearances. Road culverts were designed using HY-8 culvert analysis program.
