Following a trend that gained momentum in 2016, more improvements to residences — if not the addition of new houses — on Water Street are planned for 2017.

During its meeting Tuesday, the Washington Historic Preservation Commission will consider several requests related to Water Street residences.

Charles and Linda Hough are seeking a certificate of appropriateness to construct a two-story family dwelling at 412 Water St. and demolish the existing garage/storage shed on the northwest corner of the lot. Their application states the new house would be consistent with others in the area.

There could be an issue with the demolition request.

“This garage may not be listed on Washington’s National Register nomination, but it old and contributes to the historic district’s cultural landscape,” reads a staff report. The historic district’s guidelines states this about outbuildings and accessory structures: “Retain and preserve original outbuildings which have gained historical significance on their own.” It also reads: “Architectural elements of historic outbuildings such as roofs, siding, material, windows and doors, foundations, and character-defining detailing should be retained and preserved.”

Bill Litchfield is seeking a certificate of appropriateness to replace all wooden windows on all elevations of the house at 404 Water St. with vinyl windows. In August, the commission approved replacing siding on the house.

Terry Smithwick, with Moss Landing Marina, is seeking a certificate of appropriateness to build a wooden, white pergola on the southeast corner of the lot at 227 Water St., erect a 4-foot black or bronze aluminum fence and gate along the south and southeast property line and install a sign in the northwest corner of the lot.

A pergola is an archway in a park or garden usually covered with climbing plants.

During its August meeting, the commission approved two requests — one by A.L. “Al” Crisp and the other by Franklin D. Johnson Jr. — to build new residences on the street. Crisp plans to build a new two-story family dwelling at 416 Water St. Johnson plans to build a new one-and-a-half story residential structure at 406 Water St.

Commission members Ed Hodges, Mary Pat Musselman, Geraldine B. McKinley, Mark Everett and Cheri Vaughan voted to issue the certificates of appropriateness for the two projects, with members Judi Hickson and William Keener voting in the negative.

The commission meets at 7 p.m. Tuesday in the Council Chambers in the Municipal Building, 102 E. Second St. To view the commission’s agenda for a specific meeting, visit the city’s web­site at www.washingtonnc.gov, click “City Agendas.” Locate the appropriate agenda (by date) under the “Historic Preservation Commission” heading, then click on that specific agenda listing.
