Long Island Regional Planning Council Press Release Crosstabs Report
About the Survey
In 2025, the New York State Department of Environmental Conservation (NYSDEC) and and the Long Island Regional Planning Council (LIRPC) commissioned the Siena Research Institute to conduct a public opinion poll to identify Long Island homeowners’ attitudes and actions regarding turfgrass fertilizer usage. Between July 9 and July 28, 2025, the Siena Research Institute (SRI) interviewed 1,002 Long Islanders for this study. To ensure the survey reached the correct audience, a series of screening questions were asked at the beginning of each interview. To participate, a respondent had to be 18 years of age or older, confirm they lived in either Nassau or Suffolk County, and affirm that they lived in a home with a grass lawn that they did not rent. This screening process ensured that the findings are based exclusively on the target population. Of the final 1,002 participants, 890 identified as homeowners, while the remaining 112 lived in their home through another non-rental arrangement.
This survey was funded with New York State Environmental Protection Funds. The information and opinions presented in this document do not necessarily represent the views and opinions of NYSDEC.
