Land Uses Allowed
---------------------------------------------------------------------------------------- - - - - -- � ------------------------------------------------------------------------------------
Broad range of commercial and residential uses
allowed within the allowed building and frontage
types
• Based on the land uses allowed in the CB -5 Zone
• Some additional uses allowed and restrictions established
based on the scale and character of the subdistrict.
• Uses can be mixed both vertically and horizontally
• The regulating plan reserves specific primary
I frontages for required storefronts
• Special standards for auto - oriented uses, such as gas
stations and drive - through facilities
Parking Requirements

• Opportunity to adopt a cohesive and comprehensive set
of parking policies for Downtown and Riverfront
Crossings
Establish parking requirements for Riverfront Crossings
Revise minimum requirements for multi - family so they are
consistent across similar zones
Delete Near Southside Parking Impact Fee District
Establish new Downtown and Riverfront Crossings Parking
District to provide flexibility to reduce parking requirements for
projects that are designed to achieve public goals. Payment of a fee
in lieu of providing the parking would compensate the City for costs
associated with providing public parking to satisfy the parking
demand generated by the development
Delete option to satisfy private parking requirements within public
parking facilities without compensation to the City

Frontage Condition
A building's frontage condition - the transition
from public to private space, from indoor to outdoor
at the main entrance, the design treatment of first
story building facades, the configuration of fagade
projections, and the disposition of improvements
within required setbacks - strongly influences the
quality and character of public streets and
spaces.

Benefits of the Form -based Code
Benefits of a form -based code:
• Higher residential densities
possible, while ensuring higher
quality living environment
• Greater mix of uses possible
• Helps to reduce vehicle miles
travelled by creating a
neighborhood that is easy to serve
with transit and pleasant for walking
and biking
• Lower parking requirements
due to lower parking demand
• Lower risk to investors and long
term residents due to increased
certainty about the form of
development, which also helps to
stabilize property values
• Higher residential densities = larger
customer base for local businesses
• Increased property values
• Increased tax base
rG
I
High quality development creates a sense of place
that ensures long term value. Great places are
attractive to new residents, businesses, and
employers.
