An early grading plan has been approved and construction is underway. A plan for the townhomes and condos, as well as the hotel, has been approved by the City.

christopher performed water and sewer master planning, including preparation of the infrastructure plans for the site’s approximately 1,400 LF of 8” sanitary sewer and stubouts, as well as approximately 1,400 LF of 12” waterline.

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 traverse the site, grading the site to require minimal earthwork and preparing a Letter of Mapping Revision for encroachments into the FEMA floodplain.
