The R-4 District is intended to provide for medium- and high-density multifamily residential development, with gross densities generally above 18 units per acre. These developments may be in single or multiple structure configurations. The district's regulations are designed to provide for good-quality living environments that provide adequate open space for high-density settings.

The required rear yard area is calculated as 20% of the lot depth times the lot width. Provided that this minimum area is maintained, a portion of a residential structure may come as close as 10 feet to a rear lot line.
Note 1: Single-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.
The minimum side yard setback increases by one foot 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.
Note 5: Flexible Yard Setbacks on 80-foot Right-of-Way (or Larger), Where the Normal Minimum Setback is 25 Feet.
Front and/or side yard setback may reduced to 15 feet with specific approval by the Building Director if the setback adjustment creates no adverse conditions.
