RECREATIONAL RETIAL MALL AND OFFICE BUILDING
I. INTRODUCTION

3. A. Preamble
The District of Columbia has embarked on an ambitious city
planning scheme to reshape the city scape to accommodate the
younger generation interested in compact activity zone were
shopping recreation and work all happen in close proximity. In
part this phenomena is driven by the baby boomers who has a
age factor that make living and entertainment in the close
proximity a necessity of life. The options for boomers are
suburban senior homes or an urban area with all the needed
amenities within reach. Transportation access is also important
for both groups.
So the city Mixed Use (MU) … “zones are designed to provide
facilities for housing, shopping, and business needs, including
residential, office, service, and employment centers.”
B. Program
XYZ Corporation has acquired a 2.4 acre parcel of land on the
Connecticut Ave corridor in North West Washington DC. (See
subdivision record plat Appendix B). In partnership with the
Giant Corp., the company intends to develop a mixed use
building to include retail and office activities on the land in
keeping with the Washington DC Connecticut Ave corridor
urban plan. The project is envisioned to conform to the
implementation of the Comprehensive Plan.
II. PROJECT STATEMENT
With the influx genXers, Milennials, and an establish
population of professional and elderly people[footnoteRef:1]
the XYZ Corporation has determined through market studies
that this site will support a retail and office building. [1:

ndex.html#index ]

4. XYZ Corporation recognizes the business advantage of locating
its branch offices in close proximity to several Universities and
on the metro red line. As a result the corporation has assembled
a strategic parcel of land on Connecticut Ave NW adjacent to
the Metro line. (See also Appendix B.)
