MEMORANDUM
Date: July 12, 1984
To: City Council
From: Karin Franklin, Associate Planner
Re: Tree Regulations - Project GREEN Comments
The letters submitted to the Council by Emilie Rubright and Jim Maynard in
response to the proposed tree regulations are included in your packets
again for your convenience. Also included are excerpted relevant sections
of the tree regulations. Please refer to the specific parts of the
letters and the sections of the regulations as they are addressed below.
Letter from Emilie Rubright
General applicability - Section 36 -72(b)(2) -
The rationale behind this provision is based on the idea that zoning
should determine the density or size of a development and that the tree
regulations should not, indirectly, decrease the density or extent of
buildings or use on a site. When a lot is built upon, the required yards
determine the buildable portion of the lot. The building and required
parking may consume that buildable portion. The tree regulations should
not forcea decrease in the density or amount of land consumed by a use
permitted under the zone, by forcing a smaller building or a fewer number
of dwelling units on the lot.
The intent of this section of the tree regulations is to permit the full
development of lots, particularly in the CB -2 and RM -145 zones where
high-density development is desirable. In these zones, a buildingma be
built to the lot line to achieve a maximum density in those areas Fe 9-
nated as appropriate for high-density development. Compliance with all
provisions of the tree ordinance, particularly building coverage trees for
residential development, could mean that the building line would have to
be recessed to allow sufficient room for a tree or trees, and the intent
of the zoning to provide a place for high-density development would not be
met. If a structure does not cover the lot in these zones but is built
with yards or outside parking, trees will be required to the extent
possible.
Site plan - Section 36-72(h):
A site plan has been required prior to the issuance of a building permit
for some time. Since the spring of 1983, the planning staff has assisted
the. Housing and Inspection Services Department in the review of building
permit applications for all new construction, except single family and
duplexes, for compliance with the zoning ordinance, including the tree and
off-street parking requirements. Sufficient distances between trees and
buildings, sidewalks, and utilities is checked at that time, as dictated
by the ordinance. The City can only require, however, that which is
/'3�?7
Page 2
mandated by ordinance; there is no discretion in the issuance of a
building permit. The only provision which permits a waiver of a amo�rt of
the requirements is under the right-of-way trees provision. slsually,
compliance is obtained for all three types of trees - right-of-way,
parking area, and building coverage trees. A building permit is not issued
until compliance is shown on the site plan.
Few, if any, variances to the tree regulations have been sought or granted
in recent years. Variances to the off-street parking requirements have
been sought and some have been granted.
Inspection:
On-site inspection of construction for compliance with the approved site
plan is done by the City Forester for the trees required, or by the
Building Inspectors who also inspect for compliance with building code
requirements.
Letter from Jim Maynard
Section 36-72(b)(2):
Refer to the comment in response to Ms. Rubright's letter under this
section heading. The essence of Mr. Maynard's comment appears to be a
desire that the minimum yard requirements be increased. The yards are a
function of another part of the zoning ordinance and are not regulated by
provisions of the tree regulations.
Section 36-72(c):
The City Forester reviewed the existing List of Recommended Trees. The
list attached to the ordinance reflects his revisions. Trees not mentioned
on the list may be used if approved by the City Forester.
Section 36-72(d):
The proposed amendment sets out more clearly in the ordinance the adminis-
trative practice. Establishment of an escrow account was suggested by the
Chamber of Commerce committee as an incentive for compliance. It would be
administered in the same way that escrow accounts for sidewalks or erosion
control are handled; no interest is paid. The City would have the _o tion
of selecting the trees and planting them if the developer did not do so,
with the costs covered by the escrow account.
Section 36-72(h)(2):
Requiring specificity as to tree species with submission of the building
permit application is possible. The size of the tree at planting is
mandated by the ordinance, Section 36-72(e). Showing the location of the
tree is also required.
Section 36-72(h)(3):
This information could also be required. Permission of the City Forester
is required for the removal of any tree from the street right-of-way.
1.3-77
Page 3
Section 36-73(a)(3):
The intent of this provision was to more clearly indicate to users of the
ordinance that the city wished to have as many trees as possible on
private property and that only when this was not possible could trees be
planted in the public right-of-way by private individuals. All trees
within the public right-of-way are the responsibility of the City to
maintain.
I Section 36-73(b)(1)a.:
This suggestion also relates to other sections of the zoning ordinance
which the Council may wish to address at some other time.
Section 36-73(c)(2)b.:
The statement that this provision effectively eliminates plantings in the
side yard is true. In multi -family, commercial and industrial zones where
these regulations apply, there often is a five foot or zero side yard
e size of
devAgain,
elopment by te ard requthis irements lates oodensity control of
rementsofspecific zonesaa
and nd to the tree
regulations per se.
Mr. Maynard's final comments address, as he states, a larger issue than
the tree regulations and will require further discussion with Mr. Maynard
and the Council to reach some resolution of these concerns.

Iowa City, Iowa
Dear Mayor M:Donald and
Council,
In response to a letter
from Karin Franklin of the Planning Department
asking for Project GREEN's Steering Committee comments on the revised
t"e regulations, we would like to make the following comments.
General Applicability.
The language of thea exemption H2 is not clear.
Does the property seeking a building permit have
insufficient yaW to accomodate trees before the
planned remodeling or expansion�or will the construction
called for in the building permit cause the lack of
open space for trees?
h Site Plan
It is very good to ask for a plot plan, site plan,
to be submitted with the building plans when a
building permit is requested. However, the words
landscape plan for trees required in the City's
Ordinance should be included for clarification.
It is our recommendation that the planning department
carefully review the building plan as it relates to
owner's ability to carry out the parking and tree
ordinances. Once a building is started and the
owner;or builder finds out he cannot comply with the
tree or parking ordinances he than seeks a variance.
Careful coordination of building, parking and landscaping
plans and supervision by the planning staff would
would eliminate a lot of variance requests.
Elements of a building such as sidewalks, bike racks,
airconditioner units, overhanging balconys, window
wells, retainibg walls, transformers and such often
make compliance with the tree ordinance difficult.
These elements of design for a building need to be
part of the site plan and the landscape plan so that
planning staff could show a builder or owner how his
building plan may be heading into trouble with the
parking or tree ordinance. Again, this type of
consultation before the building permit is issued
may reduce vari nce requests. 13,77
Project GREEN page 2
The final point may cause more work for staff but it seems that
the City Forester needs help in inspecting building sites to see
that the tree ordinance provisions are met by the builder/owner.
The Forester has great demands on his time to maintain the street and
park trees of the city. But inspection is an important part of this
ordinance. He would need help in determining tree placement, caliber,
variety etc. to make sure, as the building inspector does, that the
provisions of the ordinance are carried out. Perhaps a part-time person
is needed.
Respectfully submitted,

Dear Karin:
Thank you for sending the copy of the revised tree regulations. I
offer the following comments and will be glad to elaborate further
on these items if it seems appropriate to do so.
Sec. 36-72:
(b)-(2). It would seem that the zoning ordinance should require
sufficient yards to permit the tree regulations to be met.
Unfortunately, as evidenced by much recent construction,
this is not so. The ordinance�does not seem to recognize
the need for a reasonable amount of unobstructed open ground
space to permit landscape plantings, tree plantings and
screen plantings in conjunction with a building project.
Rather, such plantings are left to compete for space in
the minimal yards prescribed with sidewalks, driveways,
vehicle parking areas, bicycle rack pads, window wells
steps, ramps, landings, electric transformers, air condi-
tioning condensers, telephone terminals, overhead balconies,
garbage can storage pads, area lighting fixtures, signs,
retaining walls, stormwater intakes, and underground gas,
water, electric, sanitary sewer, telephone and cable TV
lines. It is possible, on an interior lot, to comply with
the yard requirements and have no place left to meet the
tree regulations after accomodating all of these other
essential elements. On a corner lot, as little as 30/ of
yards along the street frontages may be useable for plantings.
I recently encountered a situation on a SF residential
lot where it was impossible to place trees in the most
desireable locations becaVSe of the maze of underground
utilities in the front yard area.
(c). This list needs a comprehensive review and updating as
soon as possible. Many desireable varieties are not
mentioned. A number of those listed are no longer con-
sidered desireable due performance or disease suscepti-
bility observed since their introduction and some are
no longer readily available.
(d). Administrative costs? Interest paid on escrowed amounts?
Who selects trees and installs if escrow funds must be
used to obtain compliance?
June 28, 1984
Tree Regulation Comments
Page 2
(h)-(2). Why not specify the actual botanical and common name
and the size at time of planting for proposed trees and
the accurate identification and size of existing trees.
It wouldn't hurt anyone to do a little advance thinking
about the selection and placement of these trees. Permit
designation of an "acceptable alternate"if a little
flexibility is needed.
(h)-(3). Suggset: "the location, type and size (caliper) of
existing trees within the right of way and on the site."
Designate "to remain" or " to be removed". How else can
it be determined from the plan whether existing trees
will fulfill part of the tree requirement? Also whether
public trees are being removed that should be replaced?
Sec- 36-73-
(3) Suggest:"Placement of trees within street rights -Of -way.
Frontage trees may be planted within the right-of-way in
those cases in which trees meet the following conditions:"
This wording provides much more flexibility in the place-
ment of trees and the design of the most appropriate
landscaping treatment for the site. The negative wording
in the proposed change unnecessarily takes away an option
that may be desireable in the limited number of cases
where it exists.
(3)-(b)-(1)a:"Sec.36-58(e)-Off-street parking requirements" refered
to here needs major revisions to permit more flexibility
and the use of imaginative design solutions for large
scale parking areas and for all other parking areas as
well. Arborvitae are not a panacea for, a permanent solu-
tion to or the most creative design tool available for
screening parking areas.
(3) -(c) -(2)b: This would require 16' to 28' between buildings to
allow trees to be placed in the side yards which is
substantially more the the zoning ordinance requires.
Present zoning and building practices essentially eliminate
any tree planting in side yards. Likewise these clearances
in combination with the elements mentioned in the first
comment above can effectively eliminate tree planting
in front, rear and street -side yards in many cases. The
solution, however, is not to reduce these clearance s.
I have mixed feelings about the 1.5" caliper minimum size but think
it is worth a try since the previous requirement was rarely, if ever,
enforced. The incentive to use 2.5" caliper trees as provided in
Sec. 36-73, (3)-(c)(2)a. is a good idea.

Tree Regulation Comments
Page 3
Revising the tree regulations, however, merely addresses a relatively
minor symptom of what has been for some time and continues, even
under the new zoning ordinance to be a major problem. That problem
is: The lack of sound, detailed, accurate, functional, comprehensive,
aesthetically pleasing site plans for the majority of new constuction
projects and the failure to use such site plans as the primary
determinate of the density of development that the site will accomodate.
Refer a gain to my first paragraph of comments. Most of the elements
mentioned rarely appear accurately, if at all, on site plans submitted
for building permits,zoning change request or Board of Adjustment
appeals. Likewise, detailed grading plans are seldom worked out in
advance of obtaining building permits. Many of the elements mentioned
appear on the site as afterthoughts or become oversights that are
inherited by new owners or occupants. And then someone wonders why
there is no place for children to play, no place for a,garden or
swimming pool, no place for a lawn party or no place for a picnic
shelter. Sometimes the parking lot doesn't seem to work, some of the
parking spaces that were on the "site plan" seem to be imaginary.
Sometimes water doesn't drain away or drains to the wrong place.
Re -grading and constructing retaining walls are expensive but not
uncommon "post construction adjustments" in Iowa City.
A properly planned development does not have to be forced onto the
site. A properly planned development will accomodate all of the
aforementioned elements compatibly, functionally and aesthetically.
A properly planned development will have a reasonably proportioned
amount of unobstrcted open space relative to the mass of the
structures and the paved areas. A properly planned development does
not destroy the natural environment from which it seeks to benefit.
A properly planned development does not pass on a legacy of problems
and unnecessary expenses: to future owners, occupants and the general
public.
It is time to consider ways and means of encouraging comprehensive
and competent site planning as a prerequisite to any new building
development including even two and four unit condominium structures
and perhaps even for single family structures on sites of irregular
topography or in heavily wooded areas.
With proper site planning, we could have greater variety, more
compatible inter -mixing of land uses, higher densities, more attrac-
tive and functional developments and fewer problems and we wouldn't
hayeAQ_,Worry about having enough room left for a few trees.
