Title to the land that much of Wyomissing is built upon was in two parcels, an eastern tract and a western tract, which were divided by a northwesterly line in the vicinity of Lake Avenue.

This area of town is also mountainous and rugged, with the border descending along a northwesterly line to the narrow Woodbury Creek valley, where NY 32 and the New York State Thruway enter the town.

The majority of the northern border of the city is a line that runs east-west just above Forbes Terrace, mostly paralleling Ruie Road, with the rest of the northern border being a short northwesterly line that runs from Ward Road to Witmer Road.

It is traversed by the northwesterly line of equal latitude and longitude.
