ZONING: "RL" (Residential Low Density)
Additional information is provided in response to the discussion and input received at
the January 9th hearing. Only the sections of the previous Report that have been
changed follow, with added information underlined and deleted information struck
through. In some cases this new information results in a change to the recommended
conditions. (The report to the Zoning Board of Adjustment for its meeting of January 9,
2013 is available on the City of Ames web site: www.cityofames.org)
General Standards
(v) Not create excessive additional requirements at public cost for public
facilities or services.
Findings of Fact: Space will be provided off the public street for school busses
and passenger vehicles to drop off and pick up students. A bus lane with a
turnaround is proposed on the north side of the building. A separate drive on the
south side of the building will accommodate dropping off and picking up children.
Off-street parking is also provided on the south side of the building accessible
from this drive.
Most of the existing residential area to be served by this school is to the north
and east of the school site. Pedestrians from this area will access the site along
Poe Avenue and Miller Avenue. There is one existing sidewalk from Poe Avenue
to the school site between lots near the south end of the site. A second mid-block
paved walk, six feet wide, on Poe Avenue is aligned with the sidewalk on the
1
south side of Steinbeck Street. The applicant proposes to build a six-foot wide
sidewalk on the east side of Miller Avenue. This will connect with existing four-
foot wide sidewalks at its north and south ends.
The Miller Avenue street pavement is the same thickness and design as other
local streets: eight inches of asphalt on a compacted earth base. Constructing
the school will result in two changes in the type of vehicles using this pavement.
During the construction period of several months, heavy trucks and equipment
will use Miller Avenue. After the school opens, four or five school busses will
access the proposed school twice each day from Miller Avenue.
Conclusions: The amount of pedestrian traffic expected requires a six-foot wide
sidewalk on the east side of Miller Avenue. Since most of these pedestrians will
come from the north, it can be expected that the existing four-foot wide sidewalk
from the subject site to the intersection of Miller Avenue and Clemens Street will
not be adequate. Therefore, it can be concluded that in order for the
development to meet General Standard (v) for a Special Use Permit the
public sidewalk on the east side of Miller Avenue should be widened to six
feet from the north property line of the subject property to the intersection
with Clemens Street, at the sole expense of the Ames Community School
District.
City of Ames Engineering staff has reviewed the weight of busses and frequency
of use and has concluded that this traffic will not create a significant impact on
the condition or useful life of the pavement. It is expected that the construction
activities may have a topical/surface impact on the pavement. The City will
document the existing condition of Miller Avenue by photos and video to be used
as a basis to determine the impact of the construction activities. If necessary, a
"Mill and Overlay" project during the completion of the school construction will
repair any surface damage and extend the life of the existing pavement.
Therefore, it can be concluded that in order for the development to meet
General Standard (v) for a Special Use Permit, the Ames Community
School District should return the Miller Avenue pavement to its previous
condition before the school opens.

(vi) Not involve uses, activities, processes, materials, and equipment or
conditions of operation that will be detrimental to any person, property, or
general welfare by reason of excessive production of traffic, noise, smoke,
fumes, glare, or odors.
There is potential for conflict between pedestrian movement on the crosswalk
across Miller on the south side of Keats and the busses using the north drop-off
drive. There may be a need for adult oversight on-site during peak times.
One of the purposes of a Special Use Permit is to "maintain sound provisions for
the protection of the health, safety, convenience and general welfare." (Section
29.1503(1) Purpose). This purpose pertains to the properties, streets and
neighborhood surrounding the subject property. In the case of the design of the
proposed elementary school, of specific concern are the interaction of
pedestrians and vehicles at the two entrances on Miller Avenue.
The applicant, in this case Ames Community Schools is responsible for safety on
the subject property. Although people and vehicles moving in the public right of
way and on and off the school property are at the interface between these two
jurisdictions, the safety of students arriving and leaving school is primarily the
responsibility of Ames Community Schools. Ames Community Schools is strongly
committed to the safety of its students and others arriving and leaving the
property and has provided the following additional information about its activities
to ensure safety during school start and end times:
Current adult supervision at our elementary schools before and after
school typically involves from 3 to 7 adults depending on the site and the
student enrollment.
At the current Edwards building:
Two adults in addition to separate classroom teachers monitor bus
loading and unloading while one adult monitors car traffic and
individual student pick-up and drop off.
At the current Sawyer building:
Four adults supervise student loading and unloading from busses
before and after school while three adults monitor car traffic and
individual student pick-up and drop off.
Obviously, adult supervision is situationally determined and monitored at
all our buildings on an on-going basis. As you can see from the above
facts, considerations for adult supervision hinge on student enrollment, the
amount of car traffic and traffic patterns at the building site, and the nature
of the streets surrounding each building.
3
At the hearing a question also was raised as to whether, on the south drop off drive, the
space is adequate for drop-off and parking movements at the same time, avoiding
congestion backed up to the entrance drive here. The attached "South Parking Lot
Diagram" provides evidence that the space is adequate.
Residential Zone Standards.
(i) Not create excessively higher levels of traffic than the predominant pattern
in the area and not create additional traffic from the proposed use that
would change the street classification and such traffic shall not lower the
level of service at area intersections.
Findings of Fact: Schools exist in five similar residential neighborhoods in Ames
Travel patterns related to schools are part of the normal and predominant travel
patterns in these residential areas An elementary school typically generates a
larger volume of traffic than a neighborhood of single family homes, particularly
peak volumes at the beginning and end of school days and, to a lesser extent,
before and after special events. Also, an elementary school of this size in the
Ames School District requires four or five school busses to arrive and depart
within a narrow time frame twice per weekday.
A traffic study was prepared in 1996 that included the projected traffic for a
school. Although the focus of that study was the overall network in the area and
the levels of service at the larger intersections, the study did determine that the
school was expected to generate 2% of the total traffic in the fully developed
neighborhood. It is now possible to improve projections by sampling the actual
traffic volumes of the built out neighborhood.
CyRide currently serves residents in this area with the #7 Purple Route during
the school year on weekdays between 7 and 9 am and 3:45 and 4:45 pm, with
two or three intervals during each of these periods of service. These busses
access the area on Mortensen Road and turn around in the intersection of
Mortensen Road and Miller Avenue, one block south of the subject property. The
instructional day for elementary students currently begins at 8:35 am and ends at
3:20 pm (2:05 pm on Wednesdays). The periods of transit service will coincide
with the peak times for traffic around the proposed school. Motorists using the
intersection for accessing the school site may be confused by the CyRide busses
making a U-turn in the intersection increasing the risk of accidents The following
four options were considered for reducing this risk:
a) Placing All-way Stop signs and flashing lights at the intersection of
Mortensen Road and Miller Avenue.
b) Reducing the extent of CyRide service such that its busses would not
come down Mortensen to Miller.
c) Having CyRide busses use the bus turnaround on the north side of the
new school building
d) Constructing a new CyRide turnaround separated from this intersection
4
After consultation between staff members from the School District City and
CyRide, it was determined that the first three options were unacceptable for
safety reasons. This left option "d" construction of a replacement CyRide
turnaround separated from the Mortensen/Miller intersection as the only viable
_alternative. The cost of this public improvement is estimated to be $50 000 to
75 000.
Under General Standard v the use proposed under the Special Use Permit ma
not create excessive additional requirements at public cost The School District
has obtained a legal opinion that the District can spend capital improvement
funds for off-site infrastructure only if the City utilizes a special assessment
district as the funding mechanism for that infrastructure
Conclusions: The pattern of the street network, street classifications, width of
streets and traffic controls at intersections with the major streets were designed
based on an earlier traffic analysis and are likely to still be adequate. At this time
it is not known if this peak school traffic will change the street classifications or
lower the level of service at area intersections below Level of Service C the
City's standard for the types of intersections affected by this traffic A new traffic
study at this time can provide better predictions of those impacts based on actual
current traffic volumes in the neighborhood. Therefore, it can be concluded
that, in order for the development to meet Residential Standard (i) for a
Special Use Permit, the Ames Community School District should provide a
traffic impact study to determine if the proposed use will result in
additional traffic that will change the street classification or lower the level
of service below "C" at area intersections.
The scope of this study will include comparing existing traffic ("No-Build
Condition") to projected traffic volumes ("Build Condition", i.e. after the school is
open - this shall be the maximum anticipated use of the facility/site including any
future additions). This study should include the intended routes and intersections
affected by school busses, transit busses, pedestrians, and vehicular traffic from
parents and staff during the morning and evening peak hours — and should also
include the anticipated number of students (both initially and with any future
expansion), based on assumed school boundaries and other study parameters
determined by City staff.
If the study determines that the proposed use will result in additional traffic
that will change the street classification or lower the level of service below
"C" at area intersections the study should provide options and
recommendations to mitigate impacts of increased traffic City staff will
verify that the data in the report supports the recommendations The Ames
Community School District should pay all non-capital costs for traffic signs
and traffic calming measures within the area west of South Dakota Avenue
and south of College Creek. The study should be completed by May 1,
2013.

It is expected that having transit busses make U-turns in a street intersection that
also becomes a primary access route to the school at the same time as peak
school traffic will increase the risk of accidents to an unacceptable level Under
existing traffic levels in this neighborhood CyRide is able to use the turnaround it
previously constructed to safely make a U-turn on its Purple Route The need to
construct a new turnaround is only made necessary by the addition of the
morning and afternoon elementary school traffic which coincides with the times
when the Purple Route serves this area. City staff and the applicant have
concluded that constructing a separate CyRide turnaround further west on
Mortensen is likely to be the most effective alternative Therefore, it can be
concluded that, in order for the development to meet Residential Standard
(i) for a Special Use Permit, a new turnaround for CyRide busses should be
constructed separated from the Miller Avenue intersection the cost for
which the City of Ames should special assess the Ames Community
School District.
Not create a noticeably different travel pattern than the predominant
pattern in the area. Special attention must be shown to deliveries or
service trips in a residential zone that are different than the normal to and
from work travel pattern in the residential area.
Findings of Fact: With 400 students and 25 staff arriving and leaving at generally
the same times every weekday by car, bus, bicycles and on foot, the
transportation patterns after the proposed school is open will be different than
currently. In addition, the travel patterns that the staff, students and people who
bring them are accustomed to for their current schools will also be different.
Given the routes of existing streets and walks, these different travel patterns may
be greatest on Wilder Boulevard, Clemens Boulevard, Miller Avenue and Poe
Avenue and the intersections of Clements with Miller and Poe.
Elementary schools exist in five similar residential neighborhoods in Ames
Travel patterns related to schools are part of the normal and predominant travel
patterns in these residential areas. An elementary school has been planned for
the subiect site since the beginning of the development of the neighborhood
within which the site is located.
Conclusions: In addition to the impacts on traffic discussed above under
Residential Standard (i) the different travel patterns may also impact the current
experience of daily living (Le., quality of life of residents of this neighborhood)
However, these expected future travel patterns are part of the normal and
predominant travel patterns in a residential neighborhood with an elementary
school. In some cases the City and Ames Community Schools have found that
creating a Safe Routes to Schools plan has helped to establish safer and more
efficient pedestrian and bicycle access to and from the school site that also
minimizes impacts on the use and enjoyment of private properties in the
neighborhood. These plans typically identify operations management and public
information activities have not typically led to public improvements
6
Therefore, it can be concluded that, in order for the development to meet
Residential Standard (ii) for a Special Use Permit, the Ames Community
School District should participate with City staff in developing a Safe Route
to Schools Plan to identify o erations, management and public information
activities to help establish safer and more efficient edestrian and bicycle
access to and from the school site that also minimizes impacts on the use
and enjoyment of private properties in the neighborhood. This Plan should
be completed by April 30, 2014. The Ames Community School District and
City of Ames should commit to working together before and after the
school opens to carry out the Plan. -The Ames r-nm
Not generate truck trips by trucks over 26,000 g.v.w. (gross vehicle weight)
to and from the site except for waste collection vehicles and moving vans.
Findings of Fact: The only large truck that will access the school is a daily
delivery by a food service truck with a gross vehicle weight of 17,950 lbs.
Conclusions: It can be concluded that in the develo ment meets Residential
Standard (iii) for a Special Use Permit
CONCLUSIONS:
Based upon the applicant's information, submitted plans, and above findings of fact, it
can be concluded that the proposed development of an elementary school in
accordance with the submitted plans will meet the General and Residential Standards
for a Special Use Permit if all of the following Conditions of Approval are met-
a) A new turnaround for C Ride busses will be constructed separated from the Miller
Avenue intersection the cost for which the City of Ames will special as Ames Community School District sess the
b) To ensure greater safety when school is in use, the Ames Community School District
will request that the Ames City Council change the on-street parking regulations on
Miller Avenue, which may include prohibiting parking on Miller Avenue when the
school is in use.
c) The public sidewalk on the east side of Miller Avenue will be widened to six feet from
the north property line of the subject property to the intersection with Clemens
Street, at the sole expense of the Ames Community School District.
d) The Ames Community School District will provide a traffic impact study to determine
if the proposed use will result in additional traffic that will change the street
classification or lower the level of service below "C" at area intersections. If the stud

determines that the Proposed use will result in additional traffic that will change the
street classification or lower the level of service below "C" at area intersections the
study will provide options and recommendations to mitigate impacts of increased
traffic. City staff will verify that the data in the report support the recommendations.
The Ames Community School District will pay all costs within the restrictions on funding sources in the Code of Iowa) such as for traffic siqns and traffic calming
measures within the area west of South Dakota Avenue and south of College
Creek. The study will be completed by May 1 2013.

4. The Zoning Board of Adjustment can table this request for a Special Use Permit and
request additional information from City staff or the applicant.
RECOMMENDED ACTION:
Following extensive discussion in the community, the Ames Community School Board is
implementing a long range plan for five elementary schools to serve our growing
community for many years to come. These schools are to be distributed throughout the
community in residential areas. This plan is consistent with the land use policies of the
City Council. Most people agree that elementary schools in residential areas make for a
high quality of life and for stronger, more enduring neighborhoods. An elementary
school at Miller Avenue has been planned since the beginning of this neighborhood. It is
likely that this is one of the reasons why many of the residents moved to this area.
Elementary schools are large and very active facilities. Clearly, there is potential
for impacts from elementary schools to be detrimental to a residential
neighborhood. Therefore, the Zoning Ordinance allows a school in a residential
neighborhood with a Special Use Permit because these impacts can be anticipated and
mitigated. This report describes those anticipated impacts and describes how the
proposed design of the school and its grounds has mitigated many of these impacts.
For impacts anticipated beyond the school site, the proposed Conditions of Approval
describe additional steps that can be taken to mitigate the remaining anticipated
impacts of developing this school.
Therefore, the Department of Planning and Housing recommends Alternative #1, that
the Zoning Board of Adjustment approve the Special Use Permit for an elementary
school in a residential zone at 820 Miller Avenue in accordance with the Site Plan
(prepared by RDG Planning and Design and dated 12/21/2012) with the adoption of the
findings of fact and conclusions stated herein and subject to the following conditions:
a) A new turnaround for C Ride busses will be constructed separated from the Miller
Avenue intersection the cost for which the City of Ames will special assess the
Ames Community School District
b) To ensure greater safety when school is in use, the Ames Community School District
will request that the Ames City Council change the on-street parking regulations on
Miller Avenue, which may include prohibiting parking on Miller Avenue when the
school is in use.
c) The public sidewalk on the east side of Miller Avenue will be widened to six feet from
the north property line of the subject property to the intersection with Clemens
Street, at the sole expense of the Ames Community School District.
d) The Ames Community School District will provide a traffic impact study to determine
if the proposed use will result in additional traffic that will change the street
classification or lower the level of service below "C" at area intersections. If the stud
determines that the ro osed use will result in additional traffic that will change the
street classification or lower the level of service below "C" at area intersections the
10
stud will provide options and recommendations to mitigate impacts of increased
traffic. City staff will verify that the data in the report support the recommendations.
The Ames CommunitV School District will pay all costs within the restrictions on
fundin sources in the Code of Iowa), such as for traffic signs and traffic calming measures within the area west of South Dakota Avenue and south of College
Creek. The study will be completed by May 1 2013
e) The Ames Community School District will participate with City staff in a Safe Route
to Schools Plan to identify operations, management and public information activities
to help establish safer and more efficient pedestrian and bicycle access to and from
the school site that also minimize impacts on the use and enjoyment of private
properties in the neighborhood. This Plan will be completed by April 30, 2014. The
Ames Community School District and City of Ames commits to working together
before and after the school opens to carry out the Plan.
f) The Ames community School District will return the Miller Avenue-pavement to its
re-construction condition before the school opens
