Concrete removal in Columbia City

The Department of Neighborhoods lists the changes that need a Certificate of Approval before the City issues any permits. They include any change to the outside of a building or structure, new construction, demolition, and any change in a public right-of-way or other public space, including parks and sidewalks. The district guidelines word it more broadly, covering the exterior of any property, building or structure visible from a public street, alley or right-of-way.

Read together, a front walk or driveway you can see from the street may fall inside that wording. The guidelines also say decorative treatments in the sidewalk, including special paving patterns and building entryway tiling, shall be preserved, and that any work affecting a street, alley or sidewalk is reviewed by the Review Committee and Board.

The district boundary is smaller than the neighborhood, and the National Register district drawn the same year has slightly different boundaries. Before you book anything, call the Columbia City Landmark District Coordinator at (206) 684-0226, which the City lists for exactly this.

The Department of Neighborhoods' history of the district says residents planned to drain Wetmore Slough and turn the town into a seaport. The port never came, and the slough was filled by 1920. The 1914 Carnegie library stands above a ravine whose creek now runs through sewer lines.

The City's critical-area maps reflect that ground. By our overlay on the Columbia City neighborhood boundary, about 3.5% lies within what the City labels the Genesee methane landfill and another 13.7% within its 1,000-foot methane buffer, and about 22% is mapped liquefaction-prone. SDCI's grading page applies the standard citywide grading thresholds in abandoned landfill and liquefaction-prone areas, such as replacing 750 square feet or more of hard surface, rather than a lower one.

In the City's Columbia City community reporting area, 46.4% of housing units are single detached homes and 45% of households own, per the 2020-2024 American Community Survey data the City publishes. The landmark district itself is, in the Department of Neighborhoods' words, a collection of commercial buildings, churches, apartments and houses, so a storefront owner planning sidewalk or entry work inside it faces the same approval step as a homeowner.
