Mr. Johnson introduced the project noting the changes from the previous
meetings. He stated that the fence was further refined because the owners felt
that the previously proposed fence, without piers, appeared too flimsy. He
pointed out the piers reintroduced along the fence and the entry walls noting
that the walls were reconfigured to be concave to reduce the prominence on
the streetscape. He stated that the walls were reduced in height. He noted that
the piers are 5 feet tall and the wrought iron fence is 4’6. He showed images of
the streetscape and the proposed overall plan.
Sam Danenberger, Mariani Landscaping, stated that adjustments were made to
the site plan in response to comments and concerns from neighbors. He noted
that deciduous and evergreen screening was increased and layered
landscaping was added in front of the curved walls and along the west and
north property lines for screening. He stated that he inspected the large, existing
evergreens to assure that the new plantings, around the perimeter of the site, will
appear natural, be compatible with existing trees and blend in with the site. He
stated that the fence will be set back from the front property line and will be
landscaped on both sides. He stated that the hedges will respect the
architecture of the residence. He stated that 8 existing trees will be saved.
Ms. McManus reviewed the background of the petition noting that the
Commission voted to approve the design for the new single family residence at a
recent meeting. She stated that consideration of the fencing, walls, pillars and
landscaping was continued to allow further refinement. She stated that the
fencing, walls and pillars were reduced in height and are now more consistent
with the streetscape. She stated that in response to concerns from neighbors,
additional landscape screening was added. She stated that the City Arborist
reviewed the plans and noted that it will be important that the new plantings be
carefully considered to avoid impacting the existing mature trees on the site and
on neighboring properties. She stated that staff recommends approval of the
fence, wall, piers and landscaping as presented.
In response to questions from Chairman Preschlack, Mr. Johnson stated that the
pillars are smaller than those in the previous plans. He stated that the depth of
the pillars was reduced from 20’’ to 16’’. He stated that the previous hedges were
fortress like and the hedges are now more transparent. He stated that the fence
along the front is wrought iron with a vertical spindle. He noted that the curved
walls were reduced in height and reconfigured to be concave, rather than
convex. He noted that the gate is similar to the previous petition, but shorter.
Mr. Danenberger clarified that the perimeter fence along the side and rear
property lines is aluminum and the front fence is wrought iron. He stated that the
aluminum fence will be painted dark and will be very simple and blanketed with
landscaping. He stated that the fence will be set back from the property line and
landscaped on either side. He stated that the adequacy of plantings in the
northeast corner of the property will be re-examined and noted the existing oaks

trees and Norway Spruces in that area. He stated that additional plantings will be
added to enhance the buffer and soften the views. He noted that evergreens
were added to increase the screening year round.
In response to questions from Commissioner Alfe, Mr. Danenberger stated that the
fence along the side and rear property lines is a deer fence and will be taller than
the fence along the front property line. He stated that the wrought iron fence
along Barberry Lane is more human in scale.
In response to questions from Chairman Preschlack, Mr. Danenberger stated that
the setback of the fence is roughly the same as in the previous proposal, about
eight feet from the sidewalk. He noted that an arborvitae hedge is proposed
along the sidewalk. He added that there will be turf and planting beds in front of
the fence.
In response to questions from Commissioner Gayle, Mr. Danenberger stated that
the additional evergreens are proposed to address the neighbors’ previous
concerns about ambient light spillover. He added that there will be evergreens of
various sizes.
In response to questions from Chairman Preschlack, Mr. Danenberger stated that
there are variations in the set back of fences along the street in the
neighborhood. He noted that the fence location as proposed respects the spatial
character of the streetscape and will not be imposing.
Hearing no further questions from the Commission, Chairman Preschlack invited
public comment.
Joan Burke, 780 Barberry Lane, stated that she lives to the west side of the
property and the back of her home faces the new house. She stated that she
met the developer on site and reviewed the plans. She stated that she is
comfortable with the plans. She requested that trees be tall enough to provide
screening. She added that she intends to add landscaping in her yard. She
stated that she is comfortable with the front façade although it would not be her
personal choice.
Warren Harshbarger, 1150 Lake Road, stated that he lives to the north of the
property. He stated that he previously expressed concerns about the adequacy
of screening and the potential light impacts. He requested clarification on the
plantings proposed along the north property line.
In response to public comment, Mr. Danenberger stated that additional
evergreens will be planted along the north and west property lines. He added
that shrubbery will be planted on either side of the evergreens.
In response to questions from Chairman Preschlack, Mr. Danenberger stated that
Historic Preservation Commission Minutes
November 18, 2015 - Page 4
the landscape plans are conceptual in this phase and confirmed that there will
be the same density of vegetation coverage on the north and west sides of the
property. He noted that the height of the evergreens will be staggered from 10’
to 18’, and offset to minimize sight lines into the property. He stated that
evergreens can grow up to a foot a year.
Hearing no further public input, Chairman Preschlack stated that in his opinion,
the changes made are responsive to the concerns expressed earlier. He added
that the ongoing discussions with neighbors are a positive.
In response to a question from Chairman Preschlack, Mr. Johnson explained that
although the piers were reintroduced to the streetscape, they were reduced in
height and diameter in response to previous comments.
Chairman Preschlack invited final questions and comments from the Commission.
Commissioner Travers stated that he appreciates that the petitioner has
addressed the neighbors’ concerns and complimented the landscape plan. He
noted that the project as presented appears to be in accordance with the
applicable standards.
Commissioner Wheeler stated that the modifications respond to the questions
and concerns of the Commission and neighbors. He noted that the piers have
been reduced in size, but are still visually connected to the house. He stated that
the shrubbery will be visible from the street and will provide screening, but not
appear as a topiary wall. He acknowledged that since the lot is vacant the
character of the streetscape will change.
Commissioner Gayle agreed with Commissioner Wheeler. She stated that
Mariani’s plans have taken into account the neighbors’ concerns. She stated that
the landscape should be natural and provide screening to accommodate the
neighbors’ concerns. She reiterated her support of the project.
In response to a question from Chairman Preschlack, Ms. Czerniak stated that
after the landscape concept plan is approved, a final landscape plan, drawn on
the approved grading and drainage plan, will need to be submitted for final
approval by the City Arborist. She offered that at that point in time, the plans can
be made available to the neighbors. She suggested that the plantings along the
north and west property lines could be planted early in the construction process
adding that the City Arborist could offer advice on location and spacing as the
plantings occur. She added that the trees will need to be spaced to allow for
growth.
In response to a question from Commissioner Alfe, Ms. McManus confirmed that a
condition requiring off site lighting impacts to be minimized was included in the
earlier approval for the residence. She stated that staff will review the lighting

November 18, 2015 - Page 5
plans for consistency with the City’s lighting guidelines.
Ms. Czerniak added that fixtures should direct light downward, the source of light
should be shielded and exterior lights should be on an automatic timer to turn off
by 11pm.
Commissioner Schaefer thanked the petitioner for responding to the earlier
comments and stated that the project is visually compatible with the streetscape.
He added that it is important to recognize that the landscaping will change and
grow over time and will look different than what is presented.
Hearing no further comments, Chairman Preschlack invited a motion.
Commissioner Travers made a motion to grant a Certificate of Appropriateness
approving a fence, pillars, entrance walls, entry gate and landscaping on the site of
new construction planned at 810 Barberry Lane based on the findings detailed in the
staff report and incorporating the testimony and the Commission’s deliberations as
additional findings. He noted that the approval is subject to the following conditions.
1. If any modifications are made to the plans presented to the Commission either in
response to Commission direction, or as the result of final design development,
the modifications shall be clearly called out on the plan and a copy of the plan
originally provided to the Commission shall be attached for comparison
purposes. Staff is directed to review any changes, in consultation with the
Chairman as appropriate, to determine whether the modifications are in
conformance with the Commission’s direction and approval prior to the issuance
of any permits.
2. Upon receipt of the final landscape plan by the City, City staff is directed to
contact the neighbors who voiced concern about screening and landscape
coverage and make the plan available to them for review and comment.
3. A final landscape plan shall be drawn on the approved grading and drainage
plan and will be subject to review and approval by the City’s Certified Arborist.
The final landscape plan shall include the following:
a. Trees worthy of and able to be preserved, as identified by the City’s Certified
Arborist, are properly protected during construction and if appropriate,
treated pre and post construction to increase the chances of survival. If
needed, trees shall be relocated on the site.
b. Enhanced screening along the west, north and east property lines.
c. Replacement tree inches are properly calculated and that the required
replacement inches are planted on site or, if replacement plantings cannot
be accomplished on the site consistent with good forestry practices as
determined by the City Arborist, payment in lieu of onsite plantings may be

accepted by the City to support parkway plantings in the general vicinity of
the project.
d. The declining oak tree at the north property line should be evaluated by a
Certified Arborist to determine if it should be removed. If the tree is removed,
evergreens shall be planted for additional screening.
e. The mature oak near the north property line and the mulberry tree near the
sidewalk should also be evaluated by a Certified Arborist.
f. Demonstrate how the proposed screening along the west property line will not
adversely impact the existing sugar maple.
g. The mature Norway spruce at the southwest and east ends of the property
should be protected and preserved.
4. An exterior lighting plan shall be submitted and will be subject to staff review and
approval prior to the installation of any exterior lights. Exterior light fixtures shall
direct light downward and limit light spillover. Exterior light, except for security
lights, shall be turned off no later than 11 p.m.
5. This project must abide by all of the terms, conditions, restrictions, and provisions
of The City of Lake Forest City Code and all other applicable codes, ordinances,

5. Consideration of a request for a Certificate of Appropriateness for demolition of an
accessory structure, a greenhouse, on the property located at 902 N. Green Bay
Road.
Owners and Representatives: John and Stephanie Harris
Chairman Preschlack asked the Commission for any conflicts of interest or Ex
Parte contacts, hearing none; he invited a presentation from the petitioner.
Ms. Harris provided an overview of the property noting that the greenhouse is
located at the corner of the lot and is screened by trees. She stated that the
greenhouse is a danger due to its state of disrepair. She added that there is a
missing staircase with a 3.5’ drop and the lead paint is peeling. She stated that
the greenhouse has significant structural issues and does not have the artistic
merit it was initially thought to have. She explained that attempts were made to
relocate the structure, but were unsuccessful due to the extent of deterioration
and significant cost of relocation. She added that the greenhouse is not visible
from the public streetscape and therefore, removal will not be detrimental to the
historic district. She stated that a rock retaining wall will be repaired where
needed and the area will be re-sodded after the structure is removed.

Ms. Benjamin, Preservation Consultant, introduced Gwen Summers Yant to
present the historic assessment report.
Ms. Yant stated that the greenhouse was part of the Donnelley estate. She stated
that the estate was originally 4 acres and the main house was accessed by a
private drive. She added that the greenhouse is located at the northeast corner
of the property and recessed behind the existing coach house. She stated that
other greenhouses in Lake Forest were designed by architects. She stated that
the estate, referred to as Clinola, was designed by Howard Van Doren Shaw in
1910. She stated that the Donnelleys were avid gardeners with significant
gardens; however, a greenhouse was not part of the original estate plan. She
stated that the greenhouse was manufactured by the Foley Greenhouse
Manufacturer who specialized in commercial greenhouse structures and high
end residential properties. She showed images of other Foley green houses in
Lake Forest which all had masonry potting sheds. She noted that although they
are handsome structures, they are not outstanding architectural examples. She
stated that the Donnelley greenhouse was the smallest model available
constructed of simple board form concrete, with a single entry with a decorative
canopy, trellis supports and a decorative finial. She noted that the structure is in
disrepair with peeling paint, rusted gutters, missing steps and serious spalling. She
added that there are gaps in the windows, missing windows and the hot frames
are significantly deteriorated. She showed images of the interior of the
greenhouse noting that the original venting machine is intact. She concluded
that demolition is appropriate due to the deteriorated condition of the structure,
its location away from public view, its later construction date and the fact that it
was constructed of standard parts.
Ms. McManus stated that the petitioner is requesting approval of the demolition
of the greenhouse and noted that no replacement structure is proposed. She
stated that the area will be restored to lawn. She noted that staff finds that the
petition meets the demolition criteria and pointed out that the structure was
found to not be historically significant to the estate. She added that the structure
is significantly deteriorated and restoration would essentially be a replacement of
the existing structure with a new greenhouse.
In response to questions from Commissioner Travers, Ms. Yant acknowledged that
the greenhouse is listed as a contributing structure, but noted it is not an integral
part of the country house estate and was constructed as a later addition to the
site.
In response to questions from Chairman Preschlack, Ms. Yant stated that the Foley
greenhouses were built from stock parts . She added that they were customizable
to an extent to meet customers’ needs.
In response to questions from Commissioner Travers, Ms. Yant stated that the Foley
greenhouses were not high end or architect designed like many greenhouses in
Historic Preservation Commission Minutes
November 18, 2015 - Page 8
Lake Forest.
Chairman Preschlack noted that historical significance is determined in part
based on the importance and relationship of the structure to the broader estate,
a relationship that is not significant in this case.
In response to questions from the Commission, Ms. Benjamin stated that
greenhouses were often part of estates, but the Donnelley green house was
constructed decades after the original house and was not part of the original
estate plan.
Ms. Yant stated that other greenhouses in Lake Forest are larger, architect
designed, and more sophisticated. She added that Foley produced high end
greenhouses and conservatories that were important elements to estates and
integral to their landscapes, but that is not the case here.
Ms. Czerniak stated that the owner contacted representatives of Elawa Farm to
explore donation and relocation of the structure. She stated that based on the
advice of various experts, it was determined that the relocation was not
workable. She added that after significant efforts by the petitioner to find ways to
save or relocate the structure, this petition was brought forward reluctantly.
In response to comments from the Commission, Ms. Harris stated that she would
have restored the greenhouse herself if it was beautiful and worth preserving. She
added that a structural engineer determined that 97 percent of the structure
would require placement in order to restore it. She stated that it was constructed
37 years after the home.
In response to questions from Commissioner Travers, Ms. Benjamin explained that
eligible structures are identified as contributing to flag them for further study when
in the future changes or demolition is proposed. She noted that some
contributing structures are supported by substantial data; others are identified as
a protective measure to assure that careful consideration occurs as has
happened in this case.
Chairman Preschlack summarized that contributing structures warrant further
evaluation, but are not protected in perpetuity. He stated that the Commission’s
role is to assure that further evaluation occurs and that proper decisions are
made based on the evaluation.
In response to a question from Commissioner Travers, Ms. Yant stated that she is
unaware if there are available parts for the greenhouse. She added that the
greenhouse is a secondary structure and is one of Foley’s most simple examples.
In response to a question from Commissioner Wheeler, Ms. Harris stated that the
greenhouse was last used by the Chandlers, the previous owners. She added
Historic Preservation Commission Minutes
November 18, 2015 - Page 9
that at one time, the Lake Forest Garden Club used it, more than 10 years ago.
Commissioner Wheeler stated that the structure is elegant and made of
components that could be reassembled, but it has outlived its useful life. He
added that there is limited sun for the greenhouse in its present location. He
stated that the report provides thorough historic documentation of the structure.
He suggested that measured drawings could be done to further document the
structure.
Hearing no further questions from the Commission, Chairman Preschlack invited
public comment. Hearing none, he stated that he appreciates the questions
raised by Commissioner Travers. He noted that it is the Commission’s role to
interpret and apply the criteria to each petition. He noted that based on the
criteria, some contributing structures may be worth preserving and others may
not be. He acknowledged that this is a difficult petition but noted that the
greenhouse was a later addition on the estate property, but not a prominent
aspect of the estate. He stated that in his opinion, demolition of the greenhouse
would not be a disservice to the town. He stated that there needs to be a
balance between preservation and the renewal of properties. He stated that the
Commission is not the Lake Forest Preservation Foundation and must take a
balanced approach. He added that he is comfortable with the demolition, but
appreciates the hard look based on the criteria.
Commissioner Schaefer stated that in his opinion, the 5 criteria are met and the
Commission’s decision should be based on the criteria, not on other
considerations. He added that the structure is interesting, but not architecturally
unique.
Commissioner Alfe stated that looking at the original estate plan; Shaw would not
have designed the greenhouse that was later constructed.
Commissioner Gayle stated that the overall estate has a strong pedigree, but the
greenhouse is not at the same level as the rest of the estate. She noted that it is
not unreasonable to say it is historic but noted that it would require great lengths
to restore or reconstruct the structure given the state of deterioration.
Commissioner Travers stated that it is difficult to accept the historic information
and conclude that the criteria necessary to support demolition are satisfied. He
stated that, in his opinion, the proposed demolition does not satisfy the standards
because the structure is pertinent to the country house era, was constructed by a
renowned manufacturer and has architectural significance.
Chairman Preschlack re-stated that demolition would not be detrimental to the
public.
Commissioner Travers stated that the structure contributes to the character of the
district and is identified as a contributing structure to the district. He added that
Historic Preservation Commission Minutes
November 18, 2015 - Page 10
demolition is contrary to the intent of the preservation chapter in the Code. He
stated that the greenhouse is of uncommon design and materials and could not
be reproduced easily. He added that previous petitions have reminded him that
it is difficult to replicate or incorporate historic elements into new construction.
Chairman Preschlack stated that preservation is not static and the Commission
has to make judgement calls on whether the standards are met considering the
unique facts of each petition.
In response to a comment from Commissioner Travers, Chairman Preschlack
agreed that information about the interior and cost of restoration is not under the
Commission’s purview.
Hearing no further comments, Chairman Preschlack invited a motion.
Commissioner Travers made a motion to grant a Certificate of Appropriateness
approving the demolition of the greenhouse located at 902 Green Bay Road. He
noted that the approval is subject to the following conditions.
1. The Historic Resource Assessment shall be preserved in the City’s archives
pertaining to this property and shall be made available to the Historic Society.
2. A restoration landscape plan for the area shall be provided.
3. If applicable, prior to restoration or repair of the adjacent retaining wall, permits
shall be obtained.
4. If determined to be necessary by the City’s Certified Arborist, tree fencing shall
be installed to protect nearby trees and vegetation during demolition.
5. Demolition activity must begin within 30 days of installation of construction and site
protection fencing and demolition activity must be continuously pursued to
completion to minimize disruption to the neighborhood.
6. This project must abide by all of the terms, conditions, restrictions, and provisions
of The City of Lake Forest City Code and all other applicable codes, ordinances,
rules and regulations.
Commissioner Wheeler seconded the motion and the Commission voted 5 to 1 to
approve the petition with Commissioner Travers voting nay.
