The Challenges
The Westside Townhouse development is comprised of 54 front-loaded townhouses on private streets and is part of a larger 56.63 acre mixed-use development that also includes apartments, a hotel, and a retail center. The property was annexed in to the City of Laurel and built on reclaimed land that had been previously mined for sand and gravel. A large sediment control trap needed for the mining operation had to be enlarged and converted to a sediment control basin. The basin was subsequently converted to a MD-378 pond to treat runoff from the multi-family, public street and townhouse developments. Designing sewer and storm drain systems for the townhouse parcel was especially challenging because gravity flow of the systems required detail coordination of grading and sewer and storm drain design to overcome a ridgeline that ran through the center of the property.
The Solution
GLW provided full entitlement processing services from rezoning to annexation exhibits to site plan approval; and full engineering services including subdivision platting, site grading, utility design, public road design, ADA compatibility, sediment control and stormwater management (SWM) and construction permitting.
Site grading of the apartment and townhouse parcels was designed early in the development process to allow sewer and storm drain construction for the adjacent apartments to move forward. Sewer and storm drain alignments and profiles were designed to minimize extra depth trenching to keep construction costs on budget.
Additionally, site grading and SWM focused on designing a submerged gravel wetland that could handle both environmental site design (ESD) and 100 year attenuation for downstream flooding for most of the property.
GLW provided detailed coordination with State Highway Administration (SHA) and Prince George’s County Department of Public Works and Transportation for an ongoing Rte 95 interchange construction that included a wholesale re-alignment of roadways that were adjacent and provided access to the property.
