Mount Vernon Gateway

Fairfax County, Virginia

The site included a proposed high-density mixed use residential and office/retail complex. A substantial portion of the site was to be developed with underground parking.
The site was bounded on all three sides by public streets which were required to be improved, including substantial widening and improvements to US Route 1. The site was also impacted by overhead utility poles, many of which needed to be relocated or placed underground in conduits through the project in a manner that would not impact the overall site development and in particular could be designed around the proposed parking structures. The project also was designed to provide Stormwater Management and Best Management Practices (BMPs) for approximately 16 acres of offsite commercial area that was not being treated with any water quality facilities. CPJ also performed various survey tasks such as: Boundary and Topographic Survey(s), as-builts of existing sanitary and storm sewer infrastructure and Horizontal & Vertical control networks, Preparation of record plats as well as on-site and offsite easement plats for the subject and adjacent properties.
