christopher faced a unique design challenge on the residential portion of the Manassas Gateway project due to the high density of the project. The design is intended to be an urban project which led to little space for necessary utilities. christopher worked closely with the developer and the City of Manassas to ensure the project meets all applicable requirements and is economically feasible. On the commercial portion of the project, challenges include addressing a sanitary trunk sewer line that traverses the site, grading the site to require minimal earthwork and preparing a Letter of Mapping Revision for encroachments into the FEMA floodplain.
