The City of Mount Vernon Architectural Review Board approved a certificate of appropriateness for a roofed side porch and a rear deck at 20 Lexington Avenue in the single‑family district. The owner’s representative described an urgent need to address water and foundation issues at the side entrance; the board approved the porch portion and the rear deck as presented.
The applicant's representative said the house has existing water intrusion and foundation damage and that the porch work addressed an urgent need. Commissioners asked about materials and finishes; the applicant said the deck would use composite decking with a wood look and that railings and lighting were planned in darker tones. One commissioner requested that the applicant confirm the number and placement of railings to avoid a “commercial” appearance; the applicant said they would explore alternate solutions such as placing railing elements in the wall instead of between columns.
The board moved to approve the application “as submitted.” The vote was recorded as aye by the members present and the applicant was told to submit any cut sheets or details needed for the final file.
