Owner: The City of Lake Forest
Tenant/Petitioner: Elawa Farm Foundation
Representative: Austin DePree, architect
Chairman Preschlack asked the Commission for any conflicts of interest or Ex Parte
contacts.
Commissioner Athenson stated that she spoke with Joanne Miller about the history of
Elawa Farm, but did not discuss details of the project.
Hearing no other declarations of conflict or Ex Parte contacts, Chairman Preschlack
invited a presentation from the petitioner.
Mr. DePree stated that a previous proposal for a new greenhouse at Elawa Farm was
before the Commission in August. He noted that since that approval, revisions were
made to further reduce the scale of the greenhouse. He explained that as a result, the
project is back before the Commission for further review. He noted that the historic

awning is now over the door as a follow up to a suggestion from the Commission. He
reviewed the revised plans noting that changes were made as the shop drawings were
finalized. He noted changes to the roof slope, lite configurations, a slight increase in the
footprint, the incorporation of the historic awning and the elimination of the perimeter
fencing. He showed contextual photos of the overall site and historic photos noting
that there were 2 greenhouses on the site during the history of the farm. He noted that
the plan as revised is intend to emulate the older of the two green houses. He
commented on the changes made to the roof slope and pitch acknowledging that the
previous proposal focused on matching the roof pitch to the pitch of the roof of the
existing potting shed. He showed comparison elevations and perspectives of the
previous and current proposals noting that the lower profile roof diminishes the scale of
the green house. He stated that the footprint slightly increased by a matter of inches.
Ms. McManus stated that through finalizing the design, further refinements were made
to the greenhouse. She noted that the greenhouse as now proposed is more consistent
with the earliest greenhouse and that the historic awning is now incorporated into the
design. She noted that in response to previous comments of the Commission, a
condition of approval was added limiting the use to the temporary storage area to 6
months. She stated that staff has become aware that some landscaping was removed
from the site in preparation for construction and recommended that a replacement
landscape plan be required demonstrating that an adequate buffer between the
animal cages and the greenhouse be provided.
In response to questions from Commissioner Athenson, Mr. DePree stated the earliest
greenhouse at the farm had a lower pitch roof noting that the revised plans are more
consistent with that structure. He stated that a completely custom greenhouse is not
possible due to budget constraints, but that the intention is to match the proportions,
scale and wood door of the earliest greenhouse. He added that reclaimed brick and
limestone to match the existing structures will be used. He added that the diminished
scale of the greenhouse is more proportionate to the more significant farm buildings
and allows the potting shed to be more visible.
In response to questions from Chairman Preschlack, Mr. DePree stated that the 2 earlier
greenhouses were in different locations, one generally in the footprint of the
greenhouse now proposed and the other, extending south from the potting shed
toward the cottage. He stated that the curved eave detail is common to 1920s
structures and the gabled greenhouse is a later adaptation possibly from the 1940s or
50s. He added that the curved shape seems the most appropriate for the site.
In response to questions from Commissioner Athenson, Mr. DePree stated that the
greenhouse will be constructed from a standard kit that will be customized. He stated
however that there are some limitations. He stated that a local contractor will be used
to construct the structure. He stated that the roof pitch was driven by design not solely
budget. He added that the pitch is more appropriate and sensitive to the site.

In response to questions from Chairman Preschlack, Mr. DePree stated that the initial
greenhouse design included a head house and a much larger green house. He stated
that once a contractor was engaged, it became clear that some design changes were
necessary.
In response to questions from Commissioner Schaefer, Mr. DePree stated that
integrating the awning and wood door will increase the cost of the project he
reiterated that economics played a role in the design, but was not the sole determining
factor.
In response to questions from Commissioner Alfe, Mr. DePree stated that spire finials
could be considered for the roof line. He confirmed that the aluminum will be painted
white.
In response to a question from Commissioner Schaefer, Mr. DePree stated that originally,
the finials likely functioned as lightning rods.
Commissioner Gayle stated that the lower greenhouse is less obtrusive and a good
solution.
In response to a question from Commissioner Athenson, Mr. DePree clarified that the
only change to the door from the previous proposal is that a wood door is now
proposed.
Hearing no further questions from the Commission, Chairman Preschlack invited public
comment.
Jim Obsitnik, resident and member of the Lake Forest Preservation Foundation, stated
concern about the roof pitch now proposed. He stated that the roof pitch should not
be adjusted in order to pay for restoring the awning and a wood door.
Commissioner Preschlack stated that cost is not a consideration of the Commission
noting that the Commission’s focus is on the design intent and inspiration.
Mr. Obsitnik stated that the greenhouse location is different than the historic location
and stated that the previously proposed steeper pitch was more appropriate for the
greenhouse at the proposed location noting that it complimented the potting shed. He
stated that there could be a way to maintain the steep roof pitch and keep the awning
and door.
Hearing no further requests to speak, Chairman Preschlack invited a response to public
testimony from the petitioner’s representative.
In response to public testimony, Mr. DePree reiterated that economics did not drive the
design. He added that the location of the greenhouse as proposed is the location of

October 28, 2015 - Page 4
one of the earlier greenhouses. He noted that extending the greenhouse to the south,
the location of the other earlier greenhouse, is not practical given the current uses of
the farm. He stated that the design currently proposed is consistent with historic
greenhouses and appropriate for the site.
Chairman Preschlack invited final questions and comments from the Commission.
In response to questions from Chairman Preschlack, Ms. Czerniak confirmed that the
standards considered by the Commission offer latitude when reviewing designs and
require interpretation as applied to each petition. She added that it in the past, the
Commission has determined that it is important to differentiate a new structure from
historic structures on the site. She noted that from the staff’s perspective, reducing the
roof pitch allows the farm buildings to be more prominent. She confirmed that in the
late 1990s, when the City acquired the property, there was a greenhouse extending
from the south side of the Potting Shed. Commissioner Athenson stated that she sees
the greenhouse as an addition to the potting shed and as such, the roof pitch is an
important consideration. She stated that in her opinion, the current design seems to be
more dominant and does not blend in with the other farm buildings as well as the
previous proposal. She added that the criteria the Commission must consider notes that
roof pitches should be compatible. She stated that the new design looks more
contemporary than the previous proposal. She complimented the integration of the
historic awning, but noted that in her opinion, overall, the new greenhouse does not
meet the criteria. She stated that she is not concerned with the increase in footprint, but
is concerned with the roof pitch and muntins as they appear more contemporary. She
concluded stating support of the previous design.
Commissioner Travers stated that the greenhouse is a simple utilitarian structure and
stated that in his opinion, the revised design refers more directly to the historic green
house.
Chairman Preschlack stated that he is supportive of project, but is sensitive to
Commissioner Athenson’s concerns. He added that roof pitches can be compatible
and not necessarily match.
Commissioner Schaefer complimented both designs and stated that in his opinion, the
revised design looks more historic and fits better on the site than the previous design.
Commissioner Alfe stated that the greenhouse as now proposed, is less imposing and
the lower roof is more appropriate for site. He stated that there are considerations in
addition to the roof pitch and noted that the overall scale is important.
Commissioner Gayle stated that she supports the smaller scale green house and does
not read the new greenhouse as modern in style. She noted that there is some virtue in
alluding to the historic greenhouse even though the location may be different.

Commissioner Travers and Chairman Preschlack agreed that adding finials to the ridge
could detract from the simplicity of the structure.
Hearing no further comments, Chairman Preschlack invited a motion.
Commissioner Travers made a motion to grant a Certificate of Appropriateness
approving revisions to a previously approved greenhouse proposed at Elawa Farm
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. Prior to the issuance of a building permit, staff, in consultation with the Commission
Chairman as appropriate, is directed to review the plans and materials submitted for
permit, and to view on site mock-ups, if determined to the necessary, to confirm that
the details of the work and the materials are consistent with the representations
made to the Commission and the Commission’s deliberations.
a. The plans should clearly detail how the greenhouse structure will be attached to
the potting shed and staff shall verify that the integrity of the potting shed is not
harmed by the proposed attachment.
2. The vegetation which provides a buffer around the animal cages shall be preserved
or, if existing vegetation is impacted, a landscape plan, identifying vegetation to be
removed or relocated and new plantings proposed, shall be submitted for review
and will be subject to approval by the City’s Certified Arborist, to assure that there is
an adequate buffer between the greenhouse and the animal cages.
3. Detailed plans shall be submitted describing how the temporary storage area
proposed to the west of the new greenhouse will be enclosed and screened from
view. A description of the materials proposed for storage in the area shall be
provided. The temporary storage area shall be removed no later than 6-months
after the date of approval or, plans for a permanent storage area or structure shall
be submitted to the Commission for review and approval.
4. Staff is directed to conduct ongoing inspections as the work progresses to assure
conformance with the Commission’s approval.
Commissioner Schaefer seconded the motion and the Commission voted 5 to 1 to
approve the petition with Commissioner Athenson voting nay for the reasons she
previously stated.

Historic Preservation Commission Minutes
October 28, 2015 - Page 6
November 14th . She stated that the Lake Forest Preservation Foundation is looking at
design guidelines from other communities and found the guidelines for the City of
Milwaukee to be very helpful. She stated that the Foundation would like to pursue
revising and reformatting the City’s design guidelines.
Ms. Czerniak stated that staff recently met with the Foundation and discussed updating
the design guidelines. She stated that it is staff understands that the Foundation is
discussion this potential project internally. She stated that staff offered to work
cooperatively with the Foundation on the update.
Commissioner Athenson stated that it would be very helpful if the Foundation tackled
the design guidelines.
5. Additional information.
Commissioner Travers informed the Commission that he recently became aware that
Highland Park has been working on an architectural survey of neighborhoods in the
community. He stated surveying properties is a common practice in neighboring
suburbs. He suggested that a similar initiative should be considered in Lake Forest
noting the valuable information that would be provided. He added that the
information should be made available to the public. He offered the information from
Highland Park to the other members of the Commission.
Ms. Czerniak confirmed that surveys were completed for each of the City’s three historic
districts. She stated that with the assistance of the Preservation Foundation, the survey
for the east Lake Forest District was updated just a few years ago. She noted that a
survey was also completed by the Foundation for the West Park neighborhood several
years ago when that neighborhood was nominated as a National Register District.
In response to questions from Commissioner Travers, she stated that staff will include the
survey sheets for specific properties in the Commission’s packets going forward. She
added that a summary and some examples of the resources available on Lake Forest
properties and neighborhoods can be provided to the Commission. She suggested
that the Commission may want to schedule a tour of recent projects in the historic
districts and a work session noting that it has been quite a while since the Commission
has done either. She stated that staff is working with the City’s mapping consultant to
explore ways to provide interactive maps on the City’s website to make historic
information more readily accessible.
Chairman Preschlack stated that the City has been at the forefront of preservation and
noted that tasks will need to be prioritized.
Commissioner Travers and Athenson agreed that the survey reports should be provided
to the Commission as background and as an objective resource.
