What are the filing guidelines?

Filing Guidelines 
Any activity proposed within 100 feet of wetland resource areas (wetlands, ponds, or intermittent streams) or 200 feet from rivers and perennial (year-round) streams must be reviewed by the Conservation Commission.  If you are planning a project which involves grading, filling, cutting, or building near a wetland resource area and have questions about which permit you should apply for, please contact the Conservation Department at (781) 314-3846.
