§ 155.204 RESIDENTIAL ZONING DISTRICTS.

(A) General. The purposes of the residential zoning districts are to:

(1) Maintain stable neighborhoods offering a range of housing choices for residents with varied incomes and lifestyle needs;

(2) Provide sufficient land in a range of residential densities to enable citizens from a wide array of economic levels and stages of life

to live in Eureka, and to accommodate the existing and future workforce;

(3) Accommodate increased development of high-density housing to balance Eureka's housing inventory and enhance affordability;

(4) Encourage the construction of new high-density multi-family housing in zoning districts where multi-family housing is allowed;

(5) Promote housing in close proximity to parks, schools, and public services;

(6) Promote new development that supports a pedestrian-friendly environment and allows residents to easily walk, bike, and take

transit to destinations;

(7) Ensure that development protects and enhances the positive qualities of existing neighborhoods and strengthens Eureka's unique

sense of place;

(8) Encourage the development of vacant lots and the redevelopment of underutilized properties;

(9) Allow improvements to existing homes consistent with the historic neighborhood character and the need to produce more housing

units;

(10) Allow for public and quasi-public uses compatible with a residential setting; and

(11) Allow limited neighborhood-serving commercial uses to enhance residents' quality-of-life where allowed by the Neighborhood

Market (NMO) Overlay Zone.
