DATE:11-25-25
DEPT:P&H
SUBJECT:ZONING TEXT AMENDMENT FOR SOUTH LINCOLN SUB AREA MIXED
USE DISTRICT (S-SMD) SINGLE FAMILY DESIGN STANDARDS
COUNCIL ACTION FORM
BACKGROUND:
On August 12, 2025, City Council gave direction to amend the South Lincoln Sub Area Mixed-
Use District (S-SMD) in response to a request from Jim Gregory. Mr. Gregory owns the home
at 129 Washington Avenue, at the corner with S. 2nd Street, which is within S-SMD. His plan
is to remove the existing house and replace it with a new house.
After discussing his building plans with staff, Mr. Gregory requested amendments to S-SMD in
order to be able to construct his preferred design. Many of the issues were driven by the site
being a corner lot and having to meet design requirements on two facades. The proposed
changes are limited to corner lot properties and change side setbacks, roof form,
facade length for single- and two-family dwellings. The changes do not apply to
apartments or commercial buildings. The changes are described in detail below.
PROPOSED ORDINANCE:
The following are the proposed changes to Article 4 and to the S-SMD base zoning district
(see Attachment A):
In Sec. 29.402, Setbacks, (4), Through Lots and Corner Lots, add an exception for
single- and two-family development to not have the same setbacks on all street
frontages.
In Table 29.1003(3), modify the S-SMD developments standards for single- and two-
family properties.
Modify the requirement for a 25 foot minimum setback to 15 feet on side streets for
corner lots
Modify a requirement for a 40 foot maximum building form to 48 feet for primary
and secondary facades
Modify a requirement for a 8 foot recessed façade to be recessed by only 4 feet
Remove the requirement for roofs to have gable end sections or at least two or
more dormers facing a street on secondary facade
In his application for a text amendment, Mr. Gregory requested that the requirement for gable
end sections or at least two or more dormers apply to roofs on all sides. This would affect both
primary and secondary façades. The design of Mr. Gregory’s proposed house, however,
complies with the requirement for the primary façade, which has a gable end. Therefore, staff
proposed only changing the secondary facade, which was agreeable with Mr. Gregory at the
P&Z hearing. Attachment A shows all changes in strikeout and underline format.
PLANNING & ZONING COMMISSION :
On November 5, 2025, the Planning and Zoning Commission reviewed the proposed text
1
amendment. The Commission heard a report from staff, including on staff's proposed change
from what the applicant requested regarding roofs on secondary facade. Mr. Gregory spoke to
the Commission and stated that he supported the staff-proposed change to his original
request.
The Commission voted 6-0-0 to recommend that Council approve the staff recommended text
amendment, with changes to the roofs only applied to secondary facades.
ALTERNATIVES:
1. Approve on first reading the amended regulations for Sec. 29.402(4), setbacks on
through lots and corner lots, and the development requirements in Table 29.1003(3) for
the South Lincoln Sub Area Mixed-Use District (S-SMD), with changes to the roofs only
applied to secondary façades per the attached ordinance.
2. Amend the Zoning Ordinance from the staff recommendation in Attachment A.
3. Take no action.
CITY MANAGER'S RECOMMENDED ACTION:
The primary issue is applying design standards to both primary and secondary facades, which
only occur with corner lots. Under current conditions there are approximately 12 corner
properties with single-family homes that are subject to the standard. The proposed change
will only apply to these 12 lots in the S-SMD zoning district. The changes will allow Mr.
Gregory to proceed with his plans as desired. These changes, however, will only apply
to single- and two-family properties. The regulations are unaltered for all other uses,
including multifamily and commercial.
The changes proposed by staff do not entirely align with Mr. Gregory’s request. Mr.
Gregory asked that the changes to the roof requirements be applied to all sides of a
building. Staff proposes that this change only applies to secondary façades. However,
the recommended changes will still allow Mr. Gregory to proceed with his proposed
design, which has a primary façade that complies with the current standard. Therefore,
it is the recommendation of the City Manager that the City Council adopt Alternative #1, as
described above.

Sec. 29.1003 “S-SMD” SOUTH LINCOLN SUB AREA MIXED-USE DISTRICT.
(1) Purpose. The intent of the South Lincoln Mixed -Use District is to ensure that this
specific area within the City’s Urban Core continues to develop as a mixed -use
area through intensification, expansion, and diversification of uses.
Redevelopment of this district is intended to integrate compact living areas in close
proximity to commercial areas and civic space and provide areas of well -defined
pedestrian emphasis. The purpose of development standards for this district is to
limit the occurrence and impact of conflicts among uses and to ensure that
development is pedestrian-oriented and compatible in scale, character, and
appearance with the traditional character of the neighborhood.
(2) Use Regulations. The uses permitted in the South Lincoln Sub Area Mixed Use
District are set forth in Table 29.1003(2) below.
