"Whereas several additions of lots contiguous to the town of Alexandria have been laid off by the proprietors of the land in lots of half an acre each extending to the north that range of lots upon the north side of a street called Montgomery; upon the south, to the line of the District of Columbia [this line had been surveyed but Alexandria had not yet been incorporated in the District] upon the west, to a range of lots upon the west side of West street, and upon the east to the river Patowmac; that many of the lots in those additions have already been built upon, and many more will so be improved; and whereas it has been represented to the General Assembly that the inhabitants residing on said lots are not subject to the regulations made and established for the orderly government of the town and for the preservation of the health of the inhabitants, by the prevention and removal of nuisances, upon which their property and well being does very much depend: "1. _Be it Therefore Enacted_: That each and every lot or part of a lot within the aforesaid limits, on which at this time is built a dwelling house of at least 16 feet square, or equal thereto in size, with a brick or stone chimney and that each and every lot within said limits which shall hereafter be so built upon, shall be incorporated with the said town of Alexandria and considered as part thereof."[40] [40] Acts of Assembly, November 1796, Chapter 32.

The charter for the town adopted by the Congress on February 25, 1804,[42] specified that the limits should be those prescribed by the Acts of Virginia. The jurisdiction of the town officials, however, was extended to the "house lately built in the vicinity of the town for the accommodation of the poor and others" and over the ten acres of ground surrounding the poor house. This is at what is now Monroe Street and Jefferson Davis Highway. Although the Charter was amended several times while Alexandria was in the District, no changes were made in the Town boundaries.

After the retrocession of "the county and town of Alexandria" (v.s., p. 13) not only were the boundaries changed, but the Town was chartered as a City. Section 22 of the new charter[43] provided:
