Frederick Law Olmsted often made use of green spaces adjacent to the landscapes he was designing as ancillary landscapes, effectively enlarging the grounds he was working on without a need to acquire more property or expend additional funds and, at the same time, buffer his grounds from intrusion. His experience in Buffalo provides more than one example of how he could incorporate these spaces to enhance his designed grounds.
To the south and east of Delaware Park (The Park) were situated the 203 acre (later enlarged to 269 acres) grounds of Forest Lawn Cemetery. To the west lay the 203 acres of the Buffalo Asylum for the Insane, both landscaped grounds and working farmland.
To the north of Front Park (The Front) was Fort Porter, then relatively little developed. Specific arrangements were made with the federal government to allow the transit of a park drive across the bluff at the perimeter of the fort, as well as to allow access to the grounds of the post by the public.
Later, during the 1880s, the Parkside residential development (designed by Olmsted) provided assurance that the property on the north and east of Delaware Park would be a complementary residential district without tenements, commercial structures or grids of streets.
