Board waives site-plan review and grants HRB approval for retaining-wall reduction at 10 Clayton Avenue

The Planning Board unanimously voted on Aug. 6 to waive full site-plan review and to grant Architectural and Historic Review Board approval for a retaining-wall reduction and landscape redesign at the property referenced in the record as 10 Clayton Avenue.

Landscape architect Susan Jainchell presented the project and described a plan to remove several courses of a large concrete block wall, regrade slopes, add planting and boulders, and create layered lawn terraces. "The wall is just too big," Jainchell said, arguing the changes would reduce visual impact and improve ecological stewardship while a structural engineer remains on the project to certify stability.

Board members questioned erosion, soil movement and whether the applicant would import fill. Jainchell said the plan involves moving material within the site and adding topsoil and mulch only as necessary; she also said the design reduces the area of maintained lawn and increases native woodland plantings. After discussion the board voted unanimously to waive site-plan review and approved HRB action referencing plan dates and a stormwater plan.

Why this matters: The waiver allows the project to proceed with fewer procedural steps because the proposal reduces engineered features and is framed as a landscape-driven correction; however the HRB approval and stormwater conditions still require compliance and engineering confirmation.

What happens next: The applicant will formalize plan and stormwater submissions to the building department and record any required plan dates and documents prior to issuance of permits.
