Materials in the City’s Olde Town standards

The City’s Olde Town design standards, read from an archived copy of the Land Use Code from February 2024, say “Materials frequently used in Olde Town include siding, oriented vertically or horizontally; shingles; wood and materials that appear similar to wood”, with stone, brick and masonry as accents. These standards apply to new development and significant redevelopment on Olde Town lots zoned Single-Family and Duplex, and the quoted line describes the neighborhood’s usual materials. Nothing in that line concerns cleaning. The City’s Historic Landmarks page describes the Coutts Garage as “a one-story, masonry, 3-bay commercial block building with a flat roof, straightened parapet, and triangular footprint”.

WSU on wet patios, sidewalks and steps

WSU Extension’s demossing manual says that where patios, sidewalks and steps are “infrequently used” and “remain wet for extended periods of time”, moss “often causes problems”. It is a regional manual and does not mention Issaquah.
