City of Seward, NE Article 9 R-3 Urban Residential Mixed-Density District

§ 410-9.1 Purpose.

The R-3 District is intended to provide for mixed-density development, including small-lot single-family development and limited multifamily residential development, with gross densities up to 18 units per acre. These developments often are characterized by low-rise buildings in multiple structure configurations, with an emphasis on open space, convenient parking, and, in many cases, common community facilities such as clubhouses and swimming pools. This district is also appropriate for larger townhouse complexes, while still accommodating lower-density forms of development.

§ 410-9.2 Site development regulations.

Note 1: One-Family Attached and Townhouse Development.
Regulators are shown on a per-unit basis. Side yard setbacks are indicated for detached building walls.
Note 2: Multifamily Development.
No more than 12 units are permitted in any single multifamily development in the R-3 District. The minimum side yard setback increases by 1.5 feet for each one foot in height above 35 feet, up to a maximum height of 45 feet.
Note 3: Zero Lot Line and Single-Family Attached Development.
Within a common development, one interior side yard may be equal to zero for single-family detached residential use if:
1.	The normal side yard setback requirement must be maintained adjacent to any lot with an existing structure not within the common development; or not otherwise designated for zero lot line use.
2.	An easement for maintenance of the zero lot line facade is prepared by the developer and filed with the Seward County Register of Deeds, the City Clerk, and the Building Official at the time of application for a building permit.
Note 4: Flexible Yard Setbacks in Planned Districts.
The Planning Commission and City Council may vary required minimum setbacks in planned districts. However, the setback from the front facade of a garage to any public or private street right-of-way (including the boundary of sidewalks) must be at least 20 feet.

§ 410-9.3 Additional requirements.

Parking areas, accessory buildings, and garages must be at least five feet from a side or rear lot line. A greater separation from residential zoning districts may be required by Article 34.
