What Determined the Original Borders of Hoffman Estates, IL?

Question

Good stuff but why the odd borders?

Answer 1

1954 proved to be the landmark in Township history. A local farmer sold his 160-acre farm to Sam and Jack Hoffman, owners of the Father and Son Construction Company, for a subdivision in Cook County. The land, now known as Parcel A, was located east of Roselle Road between Golf and Higgins Roads. The first homeowners began to move into the new subdivision in late 1955. The homes were built on half-acre lots and sold for $14,500. Down payments were as little as $700, and the interest rate was 4-1/2%. On September 19, 1959, residents voted to incorporate as the Village of Hoffman Estates. The charter was issued on September 23, 1959. The population at the time was about 8,000, and the incorporated area was just under three square miles.
