Answers from the rulebook for Stevenson

Stevenson’s own rules

  • Local zoningPresent (with conditions)

    Land inside Stevenson city limits. The city's Planning Department lists a zoning code and zoning map with its own districts, so the city appears to administer its own zoning. The zoning code text itself was not opened.

    • Evidence is the city's Planning page listing a zoning code amendment page and a zoning map amendment page with R2, R3 and C1 district pages. The zoning code text, its adoption ordinance and its effective date were not located or opened.
    • Whether a given parcel is zoned is determined by the official zoning map; not verified for any parcel.

  • Zoning districtsPartial

    Zoning districts inside Stevenson city limits

    • The Planning page names these district pages: C1-Commercial, IO-in-town living overlay, R2-Two-Family Residential, R3-Multi-Family Residential. It also lists a zoning map amendment page. The full district schedule and the zoning map were not opened, so the list is partial.
