The Marshfield Conservation Commission slowed the progress of a major residential redevelopment at 18 Abbey Street on Wednesday, citing the need to preserve what members described as a rare example of healthy, native coastal dune vegetation. Property owner Emily Harrison and James Garfield of Morse Engineering presented plans to demolish an existing dwelling and garage to construct a new single-family home and a detached accessory dwelling unit (ADU) on the barrier beach. While the project proposes elevating the structures on wooden piles and reducing impervious surfaces by over 1,700 square feet, the board expressed concern over the impact on the existing landscape.

Member Corey Miles emphasized the importance of the site’s current state, noting that disturbing the vegetative cover has a destabilizing effect on the dune. He requested more detailed narratives regarding the coastal dune and the protection of existing species, such as eastern red cedars and black cherry trees. Administrator Mike Seele agreed that while the project moves the home into FEMA compliance, the site has pretty much reverted to natural dune-like vegetation that should be salvaged. Chair Craig Hannafin added, This is what dune vegetation should look like and we almost never see it. If the grass in front along the road can be protected during construction, that would be good.

Harrison told the board she was committed to the environment, stating, I love the frontal dunes and I'm determined that construction won't affect them. However, a debate arose regarding a patch of poison ivy in the rear of the lot. While Harrison hoped to remove it to make the area walkable, Hannafin countered that poison ivy is a native plant and a hugely valuable wildlife resource. The board requested a formal planting plan from a wetland professional and conservation markers to define the limit of work. Motion Made by C. Miles to continue the hearing for 18 Abbey Street to April 15, 2026. Motion Passed (6-0).

The Commission also confronted a significant enforcement issue at 15 Iowa Street, where an inspection for a Certificate of Compliance revealed unpermitted paving and a shed located within the 25-foot buffer zone. Seele reported that the area, originally approved as a gravel driveway, had been paved, which is typically prohibited so close to wetlands. A representative for the property owner explained the paving was done out of necessity following the passing of the owner’s husband, noting it was muddy and she was unable to park. She thought she was improving the property. It wasn't intentional.

The board maintained that ignorance of the regulations did not waive the requirement for mitigation. You just can't put anything in the 25-foot buffer—not paving, not structures, Hannafin stated. Member John O'Donnell pointed out that the shed likely required a building permit and proper setbacks from the property line. While Rick Savant, speaking from the audience, suggested the pavement might prevent gravel from being plowed into the wetlands, the board required the owner to move the shed and work with Seele on a native planting plan, including blueberry bushes, to offset the environmental impact of the driveway.

In other business, the town's beach department received the green light to improve handicap accessibility at the Zero Beach Street jetty. Cindy Castro, representing Town of Marshfield Beaches, explained that sand has naturally accreted near the jetty, creating a steep and uneven slope for those using mobility mats. We'll almost make like a light bulb shape. The slope will be easier to use for people in wheelchairs, Castro said. Because the work began on April 1, the official start of the shorebird nesting season, the town will be required to employ a monitor to ensure no endangered Plovers are disturbed. Motion Made by C. Hannafin to approve RDA 2605 to move sand to allow for the installation of the mobility mats. Motion Passed (6-0).

A septic system repair at 2036 Ocean Street was also approved as a betterment for the South River area. Rick Savant of Stanbeck and Taylor explained the project replaces an aging cesspool with a modern system and a rain garden featuring blueberry bushes. Member Bert O'Donnell lamented that the property remained on a private system, noting it's just too bad it's only one lot away from town sewage. Despite the proximity to the river, the board found the improvement significant. Motion Made by C. Hannafin to adopt special conditions and close the hearing pending receipt of an updated plan by Friday. Motion Passed (6-0).

Finally, a small-scale project at 62 Parker Street moved forward quickly. Homeowner and contractor Robert Ratando proposed relocating a staircase and rebuilding a deck using helical piles. Ratando noted he made sure they were literally pulled up instead of dug to minimize dune disturbance. Seele supported the change, stating the helical piles will be an improvement to these Sono tubes. Motion Made by B. O'Donnell to issue a Determination of Applicability for 62 Parker Street. Motion Passed (6-0). Member Jesse Platt and Member Elizabeth Lake also participated in the session, which included several procedural continuations to the April 15 meeting.
