5133 Macarthur Blvd, NW is a two-story and basement/cellar building.
The building shares a masonry party wall with the neighbor to the North.
A side yard of approxmately 8 feet is to the South.
At the rear yard is a 16 ft wide public alley.

Present plans call for a two-story and basement addition at the
Front Macarthur Blvd elevation. The side yard will remain the same.

Present plans call for a two-story and cellar addition at the
Rear Alley elevation. The side yard will remain the same.

Present plans call for excavating the rear yard and establishing
a large volume space. The top concrete slab of this space will be the
same as the existing public alley and will contain parking for 4 cars.

Present plans call for lowering the existing concrete slab. The new additions
will have new basement concrete slabs that will match this elevation.
An elevator serving all floors is contemplated.

On March 26, 2020, The Office of the DC Zoning Administrator
approved these plans. A Letter of Approval (PDRM) was issued.
This is an important step in the permitting process. Zoning is
typically the most complex portion of the permitting process for
a building project of this sort.

On November 20, 2021, a Geotechnical Report was issued. Soil samples
were excavated and an analysis performed.

Structural analysis has been performed and is continuing. The structural
analysis includes footing design that will allow the addition of a 3rd floor
addition over the entire building.

A civil engineering plan has been completed.

Structural, heating, ventilation, air conditioning, plumbing, environmental, transportation, storm water, and civil are disciplines that are reviewed by DC. These technical approvals are all feasible once zoning is approved.
