Rocco Cambareri, who died last year after a career as a head pro at courses in Westchester County, N.Y., had created a development company to create a new 9-hole, par-3 course on the site of the former Shallow Creek Golf Course, which closed in 2007. Yorktown officials are now working with a partner of Cambareri’s to extend the time for development, and efforts continue to obtain grants and raise funds, in addition to $250,000 secured from a Foundation three years ago.
