COUNCIL ACTION FORM
SUBJECT: DESIGN STANDARDS FOR SOUTHWEST GATEWAY LOCATED AT
U.S. HIGHWAY 30 AT SOUTH DAKOTA AVENUE
BACKGROUND:
On January 24, 2006, City Council received an update on planning for the community's
entryways in general and draft design standards for the Southwest Gateway in
particular. Attachment A shows the area where the standards would apply. Attachment
B is the draft of the proposed standards.
City Council directed staff to receive public input on the draft Southwest Gateway
Overlay standards by requesting written comment, conducting a public meeting, and
seeking a recommendation from the Planning and Zoning Commission, before bringing
the draft standards before City Council for direction on amending the City's Zoning
Ordinance and Map.
On March 2, 2006, staff held a public meeting to review this draft of the proposed
standards. Attachment C summarizes the comments of the five people who attended.
No developer was represented. One property owner was represented.
Recommendation of the Planning & Zoning Commission. At its meeting of April 19,
2006, the Planning and Zoning Commission reviewed the draft standards and the public
input received. By a vote of 6-0, the Commission recommended to the City Council the
following changes to the draft Southwest Gateway Overlay standards and/or proposed
zoning district area.
a. Take advantage of the opportunity presented by the areas adjacent to the common
retention pond as a central pedestrian amenity for the area.
b. Encourage and offer incentives for collaborative planning among multiple properties
and property owners to share and reduce parking.
c. Encourage and offer incentives for collaborative planning among multiple properties
and property owners to provide significant green space within the development.
d. Provide for as much planting of large overstory trees as possible.
The Manager's Recommended Action section below contains more discussion about
each of these recommendations of the Planning and Zoning Commission.

ALTERNATIVES:
1. The City Council can initiate a zoning text amendment and zoning map amendment
to implement the Southwest Gateway Overlay zoning district and standards, with
specific modifications.
2. The City Council can initiate a zoning text amendment and zoning map amendment
to implement the Southwest Gateway Overlay zoning district and standards, as
proposed by Attachments A and B.
3. The City Council can refer the proposal for the Southwest Gateway Overlay zoning
district and standards back to staff for further information.
4. The City Council can choose not to proceed further with the Southwest Gateway
Overlay standards and zoning district.
MANAGER'S RECOMMENDED ACTION:
The City Manager offers the following comments and recommendations about each
recommendation of the Planning and Zoning Commission:
a. Take advantage of the opportunity presented by the areas adjacent to the
common retention pond as a central pedestrian amenity for the area.
Facilities such as landscaped walks and plazas would accomplish this, which the
property owners can incorporate into their projects. However, the Planning and
Zoning Commission is proposing something beyond this optional approach.
Typically, this would involve either of two approaches:
• Zoning development standards requiring the amenity. The Northeast Gateway
Overlay District requires courtyards, squares or plazas. Village Residential
and Planned Residential Districts require park and open space.
Some development adjacent to the pond is already complete and design is
already underway for the rest. This type of mandatory provision has not been
part of the draft that has been distributed to developers and property owners
since January.
• Offering incentives for developing the amenity. One way to do this is to
establish this area as an Urban Revitalization Area and then develop
standards for the landscaped walks and plazas to be eligible for partial
abatement of property taxes. In the South Lincoln Urban Revitalization Area,
public plazas and neighborhood recreation facilities are eligible for tax
abatement, although no one has yet applied for the program.
The incentive approach would require additional research and development of
the criteria and various actions and public hearings by the City Council.
2
Without an expression of interest by adjacent developers, it would not be
productive to pursue this incentive approach.
If the developers and the City Council are interested in partnering to
develop areas adjacent to the common retention pond as a central
pedestrian amenity, the City Manager would recommend the incentive
approach using the Urban Revitalization Program.
b. Encourage and offer incentives for collaborative planning among multiple
properties and property owners to share and reduce parking.
Sharing parking is consistent with one of the purposes of this Community
Commercial Node base zoning district, which Municipal Code Section 29.802(1)
describes as a "services area where there is a shared attraction involving one trip
to two (2) or more destinations within a node." The City could require fewer
parking spaces if connections among the different uses encourages pedestrian
movement.
Joint use parking allowed by the zoning code is appropriate where two different,
adjacent uses have peak parking demand at different times of day. Mesa,
Arizona and Champaign, Illinois have "collective" parking standards that reduce
the parking required when commercial uses on separate parcels follow a
common site plan. Champaign provides for shared parking that is 85% of the
sum of required parking for each use, but not less than the largest amount
required for any of the uses computed separately.
For multiple parcels developing a common site plan within this overlay
district, the City Manager recommends a shared parking standard that is
85% of the sum of required parking for each use, but not less than largest
amount required for any of the uses computed separately.
C. Encourage and offer incentives for collaborative planning among multiple
properties and property owners to provide significant green space within
the development.
Providing green space is consistent with the City's intentions for its entryways as
stated in the Land Use Policy Plan. The zoning code requires "useable open
space" for some residential areas. In the Community Commercial Node, the
zoning code does not require open space. Since such useable open space
would be similar to the pedestrian amenity proposed area around the pond,
if the Council chooses to promote this type of useable open space, staff
would recommend it be incorporated into the voluntary Urban
Revitalization Program recommended above.
The Community Commercial Node base zoning district requires a minimum
"landscaped area" comprising 15% of the site area. No additional landscaping is
required in the Southeast Gateway Overlay district, where the underlying zoning
is Highway Commercial. Substantial open space and landscaping is required in
3
the Northeast Gateway Overlay district, where the underlying zoning is Planned
Regional Commercial. If the purpose of the reduced shared parking provision is
the public benefit of more attractive landscaping at this gateway area, then the
shared parking provision could be combined with an increased requirement for
landscaped area.
If the Council chooses to promote additional landscaped area, staff would
recommend that where the shared parking standard is applied, the
minimum required landscaped area comprise 20% of the site area. This
percentage is lower than the 25% required in the Convenience Commercial
Nodes but more than the 15% required in all other commercial zoning districts.
d. Provide for as much planting of large overstory trees as possible.
This is consistent with the purpose of the gateway overlay and could be
accommodated within the private property or where space is available in the
public right-of-way. Extra landscaping is required in several of the City's Urban
Revitalization Areas and as a zoning requirement in the South Lincoln Mixed Use
District and the East and West University Impacted Overlay districts.
The City Manager recommends that the proposed zoning standards include
a requirement for one Landscape Tree for every 60 feet of street frontage in
addition to all other landscaping required under Article 4 Development
Standards. Article 4 pertains to landscaping for parking lots and screening. One
tree per 60 feet of street frontage is consistent with other districts that require
additional trees.
Distinctive community entryways welcome and guide visitors into the community and
are sources of pride for residents, as well as being a policy of the City and the subject of
several other overlay districts already enacted. Therefore, it is the recommendation
of the City Manager that the City Council adopt Alternative #1, thereby initiating a
zoning text amendment and zoning map amendment to implement the Southwest
Gateway Overlay zoning district and standards, with the following modifications:
• For multiple parcels developing a common site plan within this overlay
district, a shared parking standard that is 85% of the sum of required parking
for each use, but not less than largest amount required for any of the uses
computed separately.
• Where the shared parking standard is applied, the minimum required
landscaped area comprise 20% of the site area.
• A requirement for one Landscape Tree for every 60 feet of street frontage in
addition to all other landscaping required under Article 4 Development
Standards.
4
if the City Council wishes to encourage developers to create pedestrian amenities
around the pond and/or other open space, they should direct staff to prepare for Council
action a Southwest Gateway Urban Revitalization Area and Plan for these purposes.
Staff would bring the proposals for that Area and Plan back to Council for review and for
the Council to set a date for a public hearing on the Plan.
This activity would be separate from the zoning overlay and would allow the process to
continue to amend the Zoning Ordinance and Zoning Map to create the Southwest
Gateway Overlay District. The next step in that process would be a public hearing
before the Planning and Zoning Commission on the Zoning Ordinance and Zoning Map.

sustain landscape plantings native to the area.
b) Use native tree and shrub species, or their cultivars, for the majority of trees and shrubs planted
on the site.
c) Achieve unity of design by repeating plant variety groupings and other materials, and by
coordination with landscaping on adjacent properties where appropriate (including right-of-way
streetscape designs).
d) Design parking areas with a combination of landscape plantings, screening, and buffers to avoid
the visual appearance of vast expanses of hard-surface paving, to avoid narrow strips of grass
and/or plantings and to provide larger landscape areas in strategic locations rather than smaller
landscape areas scattered throughout.
e) Fencing shall be integral and consistent with the overall design of the building and the landscape
and also shall include materials of the same type, quality and color as the principal materials of

materials of the building or landscape.
6. Drive-through facilities.
a) Locate drive-through windows, menu boards, mechanical equipment, and associated stacking
lanes to minimize impacts on adjacent properties for which zoning permits residential use.
b) Integrated such site features with the building design and screened from off-site property with
screening materials that meet at least the L2 standard.
7. Building Type. These standards are intended to promote building design characteristics that enhance
the appearance of this relatively small but highly visible entry area. They are not intended to establish
specific architectural styles or building designs, but it is intended that each building have a unified
design character using architectural grade products and materials.
a) No pre-engineered buildings are permitted that are the vertical ribbed, shallow roofed, all-metal
buildings typically found in agricultural or industrial applications similar to the hangar buildings
located at the Ames Municipal Airport or to the building at 925 Airport Road. However, the
regulations are intended to allow exterior metal material as one exterior of the materials in
designs similar to buildings located at 2321 North Loop Dr. and 2711 and 2901 South Loop
Drive.
