Ordinance amending Titles 15, 16, and 18 of the City Code to
adopt and incorporate the SUDAS Design Manual and
Specifications, General Supplemental Design Standards and
Specifications, and City of Iowa City Design Supplement and
Specifications
Whereas, the City currently uses the Iowa City Interim Municipal Design Standards for the design of public improvements, adopted in March 1996; and
Whereas, the City currently uses the Statewide Urban Design and Specifications (SUDAS) Standard Specifications, General Supplemental Specifications, and the City of Iowa City Supplemental Specifications as specifications for all public improvement projects, adopted by
resolution on May 15, 2018; and
Whereas, the City now desires to align its design standards with the specifications and currently accepted practices in the engineering industry across the state by adopting the SUDAS Design
Manual (2024 Edition), General Supplemental Design Standards, and City of Iowa City Design Supplement as the City’s new design standards for use in all public improvement projects and construction within the right-of-way, as well as any extraterritorial areas required to be built to City
standards pursuant to any fringe area agreement; and
Whereas, the City also desires to amend Title 16 to codify the specifications; and
Whereas, these new design standards and specifications necessitate amendments to other
provisions of the Code of Ordinances to incorporate necessary cross references and eliminate conflicting provisions, as well as eliminate duplicative definitions; and
Whereas, Staff has reviewed the SUDAS Design Manual and prepared the City of Iowa City
Design Supplement; and
Whereas, the SUDAS Board of Directors periodically approves general supplemental design standards and specifications in response to innovations and changes in construction technologies, methods, and materials, which are then annually incorporated into its Design Manual and Specifications; and
Whereas, Staff recommends amendments to Title 15 “Land Subdivisions”, Title 16 “Public Works”, and Title 18 “Site Plan Review” of the City Code to adopt, incorporate and align the code with these design standards and specifications.

summary of various street types. The information in this table is intended to provide guidance for the design of the street network within a subdivision, Public street rights-of-way shall be designed and constructed in accordance with the Specifications and Design Standards set forth in Title 16, Chapter 4, except for those subdivisions regulated by Article 14-2H (Form- Based Zones And Standards). When designing a subdivision, street types should be chosen based on the intended function of the street and anticipated level of traffic. The city will review the proposed streets and determine the appropriate street type based on the factors set forth in this section.
E. Measurements and Construction Standards:
1. All right of way improvements must be designed and constructed according with the design and construction standards established by the city. Said standards are on file in the office of the city engineer. Specifications and Design Standards set forth in Title 16, Chapter 4.
2. All street widths shall be measured back of curb to back of curb.
23. The minimum outside radius of the pavement of cul-de-sac bulbs and loop streets is thirty nine feet (39'). A center median is required at the center of the cul-
de-sac bulb with a minimum radius of eleven feet (11'). For loop streets a median is also required with a minimum width of thirty feet (30'). In residential areas, center medians for cul-de-sacs and loop streets are required to be landscaped to
at least the S1 standard as described in title 14, chapter 5, article F, "Screening and Buffering Standards", of this code. The subdivider's agreement shall designate and set forth procedures for property owners or a homeowners' association to maintain the landscaped area within the center median of loop streets and cul-de-sacs.

K. Cost Sharing For Street Upgrades:
1. At the discretion of the City, subdivisions may be approved that access existing public streets that do not meet the city standards Specifications and Design
Standards set forth in Title 16, Chapter 4 (“city standards”), provided the subdivider contributes toward the future reconstruction cost of bringing the segment of the subject street that abuts the subject property to City standards. When determining whether such an approval will be granted, the City will evaluate the street based on factors such as roadway surface, sight distance, anticipated traffic levels, and pedestrian/bicycle facilities. If the City permits a development to access a street that does not meet City standards, the subdivider shall contribute to the cost as follows:
g. 15-3-3 Sidewalks, Trails and Pedestrian Connections:
Public sidewalks, trails, and pedestrian connections shall be constructed in the public right of way according to the following standards:

all local and collector streets, except for connections to existing sidewalks as provided in subsection D of this section. For low volume and loop streets, as described in table 15-1 of section 15-3-2 of this chapter, the required sidewalk width
may be reduced to four feet (4').
C. Along arterial streets, a five foot (5') sidewalk is required on one side of the street and an eight foot (8') sidewalk on the other side, except as allowed in
subsection D of this section. The city will determine on which side of the street the eight foot (8') sidewalk will be placed. When an eight ten foot (108') sidewalk is required, the city, at its discretion, will either pay for the excess pavement required for the developer to install an eight ten foot (108') sidewalk rather than a five foot (5') sidewalk, or collect the estimated cost of the five foot (5') sidewalk from the developer and apply said cost to construction of an eight ten foot (108') sidewalk by the city. Any payment of excess pavement costs by the city shall be pursuant to state law.
D. In cases where the proposed sidewalk provides a connection between existing sidewalks that are less than the required width, the proposed sidewalk may be constructed to match the width of the adjacent sidewalks. However, this
modification is not allowed in cases where one end of the proposed sidewalk will provide a connection to future sidewalks for new development. In such a case, the sidewalk should be tapered to provide a transition between differing sidewalk
widths. The city will determine where along the street the transition should occur.
E. All sidewalks and trails must connect to other sidewalks and trails within the development and to the property line to provide for their extension to adjacent
properties.
G. In residential subdivisions, blocks longer than six hundred feet (600') must have midblock pedestrian connections between adjacent streets, unless said connection
is deemed to be unnecessary and is waived by the city. At the time of subdivision, these connections must be platted as minimum fifteen foot (15') wide easements; if the connecting sidewalk is greater than five feet (5') in width, the easement must be
at least twenty feet (20') wide. Within this easement a sidewalk must be constructed to city standards that is equal in width to the sidewalks to which it provides a connection. If the midblock sidewalk connects to sidewalks of two (2) different widths, the midblock sidewalk must be equal in width to the wider sidewalk. The area and sidewalk within the pedestrian easement must be maintained by adjacent property owners according to the subdivider's easement agreement in a manner similar to maintenance requirements for public sidewalks.
