The proposed Long Island Cauliflower Association site. (Credit: Tim Gannon) At its meeting last Thursday, the Riverhead Planning Board discussed whether Long Island Cauliflower Association’s proposed 42,058-square-foot retail project should be required to have a sound wall to protect residents in the adjacent residential community to the north from noise. The proposal, located on a mostly vacant lot on the northwest corner of Route 58 and Mill Road, would consist of three one-story buildings — with sizes of 17,922 square feet, 10,904 square feet and 13,232 square feet — as well as a 4,935-square-foot fast-food restaurant with a drive-thru window. The restaurant would be located on the southern portion of the property, closest to Route 58. The other three buildings would face Mill Road. North of the LICA property is Millbook Communities, a manufactured home community that’s separated from the LICA property by a row of trees.
