ORAN
Date: April 7, 1997
To: Planning and Zoning Commission
From: John Yapp, Associate Planner
Doug Ripley, JCCOG Traffic Engineering Planner
Re: Vision Triangle Amendment
At their October 9, 1996 meeting, the Board of Adjustment requested that the Commission
consider amending the vision triangle requirement in the zoning code. This request stemmed
from an application for a variance from the vision triangle requirement, for a fence which en-
croaches approximately five feet into the vision triangle. The Board found that the fence did not
inhibit lines of sight at the intersection, nor did the location of the fence pose a safety concern.
The Board felt that the problem is not with the location of the fence, it is with the way the vision
triangle is measured. Therefore, it is more appropriate to recommend changing the code than
it is to grant a variance for a specific property. Section 14-6P-2C of the Zoning Code states "at
street intersections, no fence or hedge more than two feet (2') in height above the curb level shall
be located within a triangular area, two (2) of its sides thirty feet (3(:)') in length and measured
along the right-of-way lines from the point of intersection." This definition makes no distinction
between local, collector, and arterial streets, the width of the right-of-way, the posted speed limit,
and whether or not the intersection is controlled by a stop sign, yield sign or traffic signal.
Staff considered several options in re-defining the vision triangle. Safety, in the form of adequate
sight distance and stopping distance, is the primary concern. Other concerns staff has include
the complexity of the regulation and how well it is understood by the public, the ease of enforce-
ment, and how equally the regulation treats residents on similar streets. In reviewing the City's
current vision triangle regulations, staff compared the current requirements with the American
Association of State Highway and Transportation Officials' (AASHTO) standards for stopping
distance and sight distance.
When defining an appropriate vision triangle standard for the community, there are a number of
variables that make it difficult to devise one solution that will fit every situation correctly. These
variables include the speed of traffic, the width of street pavement and right-of-way, and how an
intersection is controlled. Driver due caution is also an important issue. When entering an
intersection, it is the driver's responsibility to yield or stop as necessary, and to adjust speed to
avoid conflicts. The proposed vision triangle requirement will give drivers sufficient sight and
stopping distance, provided the driver is exercising due caution and is following the rules of the
road. Without this driver responsibility, no vision triangle will ensure there is sufficient lines of
sight at intersections.
Staff Recommendation: Vision Triangle Based on the Functional Use of the Street
Staff's recommendation is to base the vision triangle on whether a street is classified as a local,
collector, or arterial street. Staff recommends that for collector and arterial streets, the vision
triangle be measured as it is now, with the legs of the triangle measured thirty feet (30') from the
intersection of the right-of-way lines. Collector and arterial streets carry greater volumes and
speeds of traffic than local streets, and are more likely to be widened over time. Collectors and
arterials are also designed to carry more through traffic, while local street traffic is required to stop
before entering the collector or arterial traffic stream. For local streets, staff recommends that the
2
legs of the triangle be measured along the curb instead of the right-of-way line. This will result
in a vision triangle shape based on vision needs. Staff believes that it is appropriate to treat local
streets differently than arterial and collector streets because of the lower volumes and speeds of
traffic on local streets, the varying location of the right-of-way line in residential areas, and
because local streets are less likely to be widened.
Other Alternatives
In addition to the recommended solution, staff consider the following alternatives:
Alternative I: Current Definition. The current definition, with the legs of the triangle measuring
thirty feet (30') from the intersection of the right-of-way lines, is very easy to understand. The
weakness in this definition is that it makes no distinction between street classifications or right-of-
way width. While a thirty foot (30') long triangle leg measured from the right-of-way line may be
appropriate for a collector or arterial street, staff feels it is excessive for a local street.
Alternative I1: Vision Triangle Based on the Traffic Control at the Intersection. This option
bases the size of the vision triangle on the type of traffic control at the intersection. The assump-
tion is that traffic coming to a stop at an intersection does not need as large of a vision triangle
as traffic which is in motion. Under this option, staff recommends the leg of the vision triangle
be measured thirty feet (30') along the curb if there is a stop sign or traffic signal, and thirty feet
(30') from the intersection of right-of-way lines if there is a yield sign or no control whatsoever.
This measurement would hold regardless of whether the street is an arterial, collector, or local
street.
Under this definition, the required triangle would change with every addition of a stop sign or
traffic signal at the intersection. This option may also result in requests for unwarranted traffic
control (such as stop signs) so that property owners could extend their fence line or hedge further
toward the corner.
Alternative Ill: Vision Triangle Based on the Speed Limit of the Street. This option bases
the size of the vision triangle on the posted speed limits of the intersecting streets. Whether an
intersection is controlled with a stop sign or traffic signal could also be taken into account.
Although this method may custom fit the vision triangle to each situation, it would also be the
most complex to implement, and would be confusing for residents. In addition, the posted speed
limit does not necessarily reflect the actual speed of traffic. As with the option based on the type
of traffic control, the required triangle would change with every speed limit change on the street.
The Solidity of the Fence or Hedge
The solidity of the fence is how much solid, opaque material there is on the fence along its length.
The definition of solidity, for the purposes of this ordinance, is the percent of the fence, over a
random area, which is made up of solid, opaque matter, and which does not allow light or air to
pass through. A few codes from other cities permit fences up to 4 to 41/2 feet in height within the
vision triangle as long as the solidity is no greater than 20% to 50%. For example, a 3 to 4 foot
tall split-rail, open weave, or wrought iron fence with a solidity of 10% to 20% would not block
lines of sight at the intersection. Staff recommends that split-rail, open-weave, or wrought iron
fences, or hedges with an solidity of 20% or less be permitted within the required vision triangle,
up to a height of 4 feet.
3
Vision Triangle at Alleys
Staff also evaluated requiring a vision triangle at alleys. Alleys are generally 16 feet wide within
a 20 foot right-of-way, and have a speed limit of 10 miles-per-hour. It is part of the current code
that any fence or structure must be at least 2 feet from any public right-of-way, including alleys.
Alleys are designed and intended as access roads for adjoining properties; they are not designed
to carry through traffic. The design features of alleys, including the narrow road width and
numerous access points combine to limit the speed at which drivers will travel.
Staff calculated the stopping distance of a vehicle in an alley traveling 10 miles-per-hour using
the minimum available sight distance, if a fence or hedge were within two feet of the alley and
street right-of-way. Under current regulations, a pedestrian would have the minimum 2 to 2.5
second reaction time (based on AASHTO standards) to avoid a collision. It is staff's opinion that
increasing the vision triangle for alleys is unnecessary, and the increased sight distance may
invite higher speeds entering and exiting the alley, as well as more through traffic. Therefore,
staff recommends there be no change in the regulations for fence and hedge locations for alleys.
A diagram illustrating lines of sight under current standards is attached.
Staff also reviewed accident locations from 1994 to present, to see if alleys accounted for a
significant number of accidents. Less than 1% of reported accidents were related to alleys.
STAFF RECOMMENDATION
Staff recommends that Title 14, Chapter 6, entitled "Zoning" Article P "Fences and Hedges," be
amended as follows:
14-6P-2
At street intersections, no fence or hedge shall be located within a triangular area, mea-
sured as follows:
On local streets, no fence or hedge more than two feet (2') in height above the
curb level shall be located within a triangular area, with the leg of the triangle
measured thirty feet (30') along the curb from the point two streets intersect.
=
On collector and arterial streets, no fence or hedge more than two feet (2') in
height above the curb level shall be located within a triangular area, with the leg
of the triangle measured thirty feet (30') along the right-of-way lines from their
point of intersection.
w
Split-rail, open-weave, and wrought iron fences less than 20% solid are exempt-
ed from the vision-triangle requirement. The solidity is the percent of the fence
over a random area which is made up of solid, opaque material, and which does
not allow light or air to pass through.

MEMORANDUM
Date: May 1, 1997
To: Planning and Zoning Commission
From: John Yapp, Associate Planner
Re: Projecting Sign Regulations
A projecting sign is defined as "a building sign extending more than one foot out from the wall of
the building on which it is mounted." Projecting signs were prohibited following urban renewal
in the early 1970s. As you can see from the photograph below taken in 1971, projecting signs can
dominate the streetscape. If left unregulated, each projecting sign may block the view of neighbor-
ing signs, causing each business to successively install bigger, brighter and more colorful signs
in an attempt to overshadow adjacent signs.
"NE corner of Clinton & Washington Streets, 1971
Since projecting signs have been prohibited for the last several years, the downtown area has
benefited from a more park-like atmosphere, free from excessive signage blocking the view of
building facades, other businesses, and the sky. This is especially the case in the pedestrian mall.
The installation of the Uncommon Grounds projecting sign (which was permitted as a time and
temperature sign) has opened a discussion of whether or not to allow more such signs in the
downtown area. Although it is possible to have tasteful, well-placed projecting signs, it is also
entirely possible for projecting signs to be installed which detract from neighboring businesses
as well as the atmosphere of the downtown. If the downtown has benefited from the prohibition
2
against projecting signs, it may be wise to continue that policy. Staff proposes that projecting
signs continue to be prohibited, to prevent the possibility of the signs creating visual clutter in the
downtown area.
If the Planning and Zoning Commission and City Council choose to permit projecting signs, staff
recommends they be subject to conditions to protect against their becoming physically and
visually obtrusive. Staff suggests that to help ensure they remain pedestrian oriented, they should
not extend further than five feet out from the face of the building, and no part of them should be
farther than 12 feet above grade (no part shall be lower than eight feet above a public right-of-
way due to clearance requirements). To prevent projecting signs from blocking the view of a
neighboring business or building, and to encourage the pedestrian orientation of such signs, no
sign face should be larger than six square feet in size per side.
To minimize glare and obtrusiveness, staff recommends that no illumination be permitted for
projectings. To help ensure that numerous projecting signs are not erected on buildings which
have more than one business in them, only one sign per first floor business should be permitted.
Staff also recommends that projecting signs be fixed, and not be permitted to swing. This will
decrease the chance of a projecting sign falling or coming loose. The sign face should be
perpendicular to the building, and should not be more than eight inches thick.
Although the exact design of projecting signs cannot be regulated by the Zoning Code, signs
projecting over the pedestrian mall are subject to Design Review Committee approval. Because
projecting signs may have a substantial impact on the character of the downtown if they are
permitted, staff recommends that any projecting sign in the CB-10 and CB-5 zones be subject to
Design Review Committee approval. This will help ensure that the visual clutter often associated
with projecting signs will be minimized, and that they complement, rather than detract from, the
appearance of the surrounding area.

Example of small, non-illuminated projecting sign in Healdsburg, CA
Staff has submitted the information in this memorandum to the Downtown Association and Design
Review Committee for their review and comment. The Downtown Association has recommended
that projecting signs be permitted, with size and location restrictions similar to what staff has
outlined. The Design Review Committee will be considering a formal recommendation at their
April 28 meeting. Both groups have suggested that a business should be able to have either a
projecting sign or an awning sign, but not both. This would be another way to minimize the
potential visual clutter numerous projecting signs might create. Staff agrees that permitting a
business to have either a projecting sign or an awning sign, but not both, is similar to other
provisions within the sign regulations designed to limit the accumulation of signage.
Staff Recommendation
Staff recommends that projecting signs continue to be prohibited. If projecting signs are permit-
ted, staff recommends that Title 14, Chapter 6, entitled "Zoning," Article O, entitled "Sign Regula-
tions" be amended to permit projecting signs as a provisional use in the CB-5 and CB-10 zones:
14-60-5F. CB-5 and CB-10 Zones:
2. Provisional Signs:
One projecting sign per ground level business, provided it does not exceed
six (6) square feet per sign face, does not project more than five feet (5') out
from the building wall, is not less than eight feet (8') or more than twelve feet
(12') above grade, is not thicker than eight inches (8"), and provided the
business does not have an awning sign or signs. Any projecting sign must
be fixed to the building wall, or to a pole which is mounted on the building,
but may not be swinging or easily moved by wind. The sign face must be
installed perpendicular to the building wall. A business wishing to install a
projecting sign must show proof of liability insurance, and must obtain
Design Review Committee approval according to procedures and guidelines
established by the Design Review Committee prior to obtaining a sign per-
mit.
e. Awning signs, provided the business does not have a projecting sign.

Re: Portable Sign Amendment
A number of downtown businesses have made use of small portable signs for many years, to
advertise menu items, specials, sales, and other changeable messages. Although portable signs
are currently prohibited under the City's sign regulations, enforcement of them has generally
occurred only if they blocked the public right-of-way. These signs are generally less than six
square feet in size, contain a changeable message, are located near the entrance to a business,
and are light enough in weight so they can be moved inside when the business is closed. These
signs are generally located on private property, but recently have been found in the public right-of-
way as well. Examples of portable signs can be found in front of Bremer's Clothing, Blimpies
restaurant, and Bo James restaurant. These signs have generally not been a problem in the
past, although recent complaints about portable signs impeding pedestrian traffic have been
logged with the City.
In the summer of 1995, a complaint was logged regarding a portable sign in the City Plaza which
was within the public right-of-way. As a result of that complaint, the Housing and Inspection
Services Department notified several downtown businesses that their portable signs were not
permitted under the sign ordinance. Joe Murphy then submitted the attached letter requesting
that the sign ordinance be amended to permit portable signs. Again, such signs have not been
a problem until recently when some business owners have placed them within the public right-of-
way, where they have impeded pedestrian traffic. City policy and regulations should be clarified
regarding the use, size, and appropriate location of portable signs.
Many cities have outlawed portable signs altogether, because of their potential to end up blocking
the public right-of-way, and their tendency to be blown or knocked over. Staff feels, however, that
they are appropriate for use in the pedestrian oriented CB-10, CB-5 and CB-2 zones. In staff's
view, the limited use of portable signs is not objectionable, provided certain conditions are met.
To help assure that portable signs do not become large and obtrusive, the sign face should be
limited to a maximum of six feet above grade. To help assure that the portable signs remain
pedestrian oriented, staff recommends that the sign face be limited to a maximum of six square
feet in size. For comparison, the Bremer's sign is roughly five feet in height, and has a 30" x 24"
sign face (5 square feet). Portable signs should be permitted only on private property or within
a designated sidewalk cafe area, and should not block access to any doorway, so that public
access is not impeded. Finally, to help ensure that the sign is not blown over, bumped over, or
moved into the sidewalk or street, the signs shall be anchored or weighted to provide stability,
and should be removed to inside the business when the business is closed.
Staff recommends only one sign be permitted per first floor business, not one sign per business
in the building. Allowing portable signs in all commercial zones or city-wide would risk too much
visual and physical clutter in areas not oriented toward pedestrian travel. As with other signs,
portable signs would require a sign permit.
2
The Downtown Association has agreed with staff's recommendation. The Design Review
Committee is meeting on April 28 to formulate a recommendation.
STAFF RECOMMENDATION:
Staff recommends that Title 14, Chapter 6, entitled "Zoning" Article O, entitled "Sign
Regulations" be amended to allow portable signs as a provisional sign in the CB-2, CB-5,
and CB-10 zones:
14-60-5F. CB-5 and CB-10 ZONES:

To: Planning and Zoning
This is a request for a reasonable change to the sign
ordinance to allow us to continue to display a sign outside
the front of our store and many others in downtown Iowa City.
What we would like to have is amendment to allow a sign
that we carry in and out each day to promote our store.
These signs would not be allowed to impede traffic flow
and would have to be under a certain size.
We would like to meet with planning and zoning to
discuss this and to help with the writing ~f the ordinance.
Thank you f~r your assistance in this matter.

Proposed Portable Sign, Projecting Sign, and Changeable Copy Sign
Amendments
At their May 1, 1997 meeting, the Planning and Zoning Commission made
recommendations to the City Council regarding portable signs, projecting signs, and
changeable copy signs (see summary below). The Commission deferred
consideration of awning illumination, directing staff to do further research on the
definitions of awnings and awning signs. The City Council will likely set a public
hearing on the three sign code amendments for their June 3 meeting.
Changeable Copy Signs
The Commission recommended by a vote of 7-0 that their be no change to the
definition of changeable copy signs. This is consistent with the recommendations
made by the Downtown Association and the Design Review Committee. The
Design Review Committee recommended by a vote of 5-1 (Swan voting no) that
there be no change to the definition of changeable copy signs.
Projecting Signs
The Commission recommended by a vote of 6-0 (Chait voting no) that projecting
signs continue to be prohibited. The Design Review Committee also recommended
by a vote of 5-1 (Swan voting no) that projecting signs continue to be prohibited.
The Downtown Association recommended that projecting signs be permitted in the
CB-10 and CB~5 zones with size and location restrictions placed on the signs.
Portable Signs
The Commission recommended by a vote of 6-1
signs be permitted in the CB~10, CB-5, and
restrictions:
(Supple voting no) that portable
CB-2 zones, with the following
One nonilluminated portable sign be permitted per first floor exterior
storefront, provided it is placed only on private property or a designated
sidewalk cafe area, does not block access to any doorway, is moved inside
when the business is closed, and is weighted at the base to provide stability
as approved by the building official or designee. The maximum area of the
sign face shall be six square feet, and the maximum height of the sign shall
be six feet above grade.
The Downtown Association recommended that portable signs should be permitted
with size and location restrictions similar to what staff has proposed.
The Design Review Committee recommended by a vote of 5-1 (Woodson voting no),
that portable signs be permitted with the restrictions outlined above, including the
additional condition that the design of a portable sign should receive Design Review
Committee approval prior to obtaining a sign permit.
