18-14 AVENUE (AV) COMBINING ZONING DISTRICT.

The AV, Avenue, Combining Zoning District is intended to provide for maximum flexibility for developing a broad range of residential products, ranging from manufactured homes to single-family homes at varying densities. Development standards are flexible to encourage innovative design and character in the building product. Also, these regulations provide basic access and fire protection for older subdivided lands by setting minimum public health and safety standards. This district shall be applied to predominantly undeveloped older subdivided properties of urban or suburban densities, known as “paper subdivisions,” which are substandard in relationship to existing zoning and subdivision regulations with design, size, or physical improvements not meeting City standards. Such lots should be characterized by steep slopes, limited access and/or lack of adequate public services and facilities such as streets, fire, sewer or water services. Nonresidential uses are also permitted. (Ord. #271-2025, S2 (Exh. A))

The uses within the AV Combining Zoning District shall be provided as described in the Tables in Section 18-18.010 (Ord. #271-2025, S2 (Exh. A))
