Semet Residue Ponds

The Ballfield, Willis Avenue, and Semet Ponds sites extend from east to west along I-690 and State Fair Blvd - two roads that together accommodate approximately 55,000 vehicles per day. As motorists pass by these sites, they view extensive areas dominated by invasive species with low aesthetic value. The overall goal of the site improvements project is to increase the aesthetic and ecological value of the I-690 corridor in the vicinity of the project site.

The site is approximately 3.8 acres. The following activities are proposed as part of the site improvements project:

remove existing vegetation across the limits of work;
apply six inches of soil to existing soils;
limit work to northern portions for each site in order to avoid fill materials and/or future remediation areas;
introduce 54 native grass and forb species to the site, including some that are rare in New York State; and
plant approximately 30 species of native trees and shrubs.
