Washington, DC Site Design

On this Columbia Heights project in Washington, DC, DeMarr Engineering provided the Civil Engineering Plans to convert this 3-story row dwelling into a 2-unit luxury condominium.   

DEMARR Engineering was retained by the owner to produce the Civil Engineering drawings and obtain the necessary site permits. We immediately performed a field survey of the site within 1 week upon signing of our proposal. 

Following the site survey, we coordinated with the project architect to add a rear addition, rear deck, rooftop deck, and rear patio. Our site plan included existing features to be removed, proposed site conditions, elevations and grading, lot occupancy calculations, erosion & sediment control measures, DC Water utility upgrade design, and Traffic Control Plan design. Our plans were then submitted to the various DC Agencies (DCRA, DC Water, DOEE, and DDOT) and approved upon second submission.


Following plan approval, we assisted the owner in obtaining the necessary public space, occupancy, excavation, and supplemental plumbing permits. As a result, the entire project was a success.
