In order to protect these resource areas, any altering activity within 100 feet horizontally outward from the upland edge of a resource area (with the exception of riverfront area) shall be reviewed by the Commission.
C. 
"Riverfront area" is a protected resource area (which does not have a buffer zone) that is the area of land between a river's mean annual high-water line measured horizontally outward from the river and a parallel line located 200 feet away in most cases. All work in the riverfront area is subject to an alternatives analysis and must meet various performance standards. See 310 CMR 10.58, Riverfront Area, for details.
"Buffer zones" are any land within 100 feet horizontally outward from the upland edge of any resource area with the exception of riverfront area.
Any alteration proposed or undertaken in a resource area or in a buffer zone is subject to regulation under the Sherborn Bylaw and requires the filing of a request for determination of applicability or a notice of intent.
