Board presses developer on retaining walls and possible stream-buffer path

Board members repeatedly pressed the applicant on retaining-wall height, materials and impacts on yards and the stream buffer. Members said multiple long 10-foot walls along the stream corridor would feel monolithic and could require guardrails or other safety features; they urged the project team to explore tiered walls, planter solutions or alternate materials such as granite or integrated foundation walls to reduce visual impact.

A staff member had earlier advised the board that approximately 2.5 acres of the site are occupied by stream buffer and that the applicant proposed up to 1,500 square feet of retaining-wall encroachment within the 75-foot impervious-surface setback. A board member proposed a recommendation tying any required stream-buffer variance to a pervious path that would connect to the adjacent Toll Brothers path as a community benefit; the board included the pervious-path item in the recommendations forwarded to council.

Why it matters: changes within a stream buffer involve state and county buffer rules and could require additional approvals; retaining-wall design affects both neighborhood character and usability of private backyards.
