General
Design
Guidelines
2.0 Site Design
•Staff considers the location of the proposed pavilion to closely match the historic
condition (1899-1905)
2.1 Building Location, Orientation & Spacing
•Staff considers the relationship to the adjacent historic buildings is close to the
historic condition.
2.2 Streetscape and Landscape
•Staff considers the reconstructed pavilion will reinstate the historic condition of
the streetscape at east end of Clematis Dr. and that no significant landscape
features will be removed to achieve this.
•Staff considers the removal of the existing retaining wall at south-east corner of
Cottage 100/General Store may be innapropriate if the wall is a historic feature
and/or regrading could damage the structure of the cottage at 100 Clematis Dr.
2.5 Sidewalks
•Staff considers further investigation should be made to reconstruct the historic
pedestrian access to the pavilion stairs.

3.3 Decks
•Staff considers the use of natural wood for decking appropriate and that railings
should be designed to be as simple and unobtrusive as possible.
•Provide details of deck and railing finishes.
3.6 Exterior Materials
•Proposed replication of the similar materials, including natural wood posts and
canvas roof with some use of contemporary steel roof trusses and diagonal bracing
appropriate as structurally necessary. and using simple light steel railing compatible
but distinctly contemporary and indicative that these materials were not part of the
original construction.
3.7 Windows
•Staff considers the removal of existing window at 100 Clematis replacement with a
new service window may be appropriate depending on whether-or-not retrofitting
the existing window is feasible, whether the window can be otherwise stored, and
details of a proposed window design are appropriate.

Guidelines
32
4.0 Additions to Historic Structures
•Staff considers that the proposed pavilion recreation is reversible, does not destroy,
(and may enhance) the original historic character of this area of the district.
•Staff considers the free-standing nature of the proposed pavilion is appropriate and
that the subtle integration of contemporary steel with interpretative signage will
clearly indicate the pavilion is a contemporary rec-construction.
6.1 Distinction from Historic Structures
•Staff considers that additional steps may be taken to distinguish the pavilion as a
reconstruction including the integration of steel railing to achieve life safety and
ADA access.. Likewise, an interpretive sign outlining the pavilion’s history and
recreation should be considered.
8.3 Mechanical and Utility Facilities
•Staff considers the proposed relocation of gas meter appropriate.
8.8 Americans with Disabilities Act
•Staff considers the addition of an accessible ramp from the porch at 100 Clematis Dr.
will not distract from the historic character.

A. Massing
•The open sides of the proposed pavilion minimize the changes in building mass and
help to preserve the size and proportions of the existing buildings, but do not
eliminate the visual changes in mass.
B. Rooflines
•Reconstruction of historic roof pitch is proposed.
C. Windows
•Staff considers the removal of existing window at 100 Clematis and replacement with
a new service window may be appropriate depending on whether or not retrofitting
the existing window is feasible, whether the window can be otherwise stored, and
details of a proposed window design.
D. Exterior Materials
•Exterior materials primarily make use of those similar to original construction –cue
that pavilion is reconstructed can be achieved through appropriate contemporary rail
details and interpretive panel.
C. Paint Schemes and Color
•Wood finish for decking and wood railings to be determined.

Standards for
Reconstruction
34Secretary of the Interior’s Standards for Reconstruction
The Standards will be applied taking into consideration the economic and technical feasibility of
each project.
1.Reconstruction will be used to depict vanished or non-surviving portions of a property
when documentary and physical evidence is available to permit accurate reconstruction
with minimal conjecture, and such reconstruction is essential to the public understanding
of the property.
Because there are good historic photographs showing the original pavilion, staff considers
there is adequate documentary evidence to ensure an accurate reconstruction of this early
feature at Chautauqua.
2. Reconstruction of a landscape, building, structure or object in its historic location will be
preceded by a thorough archeological investigation to identify and evaluate those
features and artifacts that are essential to an accurate reconstruction. If such resources
must be disturbed, mitigation measures will be undertaken.
The construction of the pavilion will likely result in little ground disturbance, though it us
recommended that steps be taken monitor any excavation to ensure that any archaeological
resources are not disturbed. If such resources are encountered, work should cease and a
qualified archaeologist consulted immediately.

Service SOI
Standards for
Reconstruction
353.Reconstruction will include measures to preserve any remaining historic materials,
features and spatial relationships.
With the exception of a window at the east face of 100 Clematis, no historic materials
will be disturbed and proposed spatial relationships appear to be carefully
reconstructed. Steps should be taken to investigate whether the existing windows can be
modified to function as a service window. If not, staff suggests that the sash be carefully
removed and stored. Compatible new sash should be installed into existing window-
frame.
4.Reconstruction will be based on the accurate duplication of historic features and
elements substantiated by documentary or physical evidence rather than on
conjectural designs or the availability of different features from other historic
properties. A reconstructed property will re-create the appearance of the non-
surviving historic property in materials, design, color, and texture.
The introduction of some new elements and materials are proposed to achieve
structural, life-safety and universal access requirements for the pavilion. These elements
should be clearly contemporary, though compatible with the historic character of the
Dining Hall and 100 Clematis Dr.

5.A reconstruction will be clearly identified as a contemporary re-creation.
Staff considers that in combination with the limited used of steel as described an
interpretive sign should be considered to explain the history of the pavilion while
describing its reconstruction.
5.Designs that were never executed historically will not be constructed.
No design issues outside of those proposed to meet life safety and accessibility for the
reconstructed pavilion are proposed
Staff
Recommendation
Staff recommends that the Landmarks
Board approve the application with
conditions.
37
Recommended
Conditions of
Approval
1. The applicant shall be responsible for completing the work in compliance with the
approved plans dated February 12, 2021, except as modified by these conditions of
approval.
2. a. Provide an excavation plan with protocols in the event of encountering
archaeological artifacts during construction of the pavilion;
b. Provide details of age of retaining wall proposed for removal and details
ensuring that its removal doesn’t lead to damaging 100 Clematis Dr;
c. Further investigate historic access to pavilion stair and attempt to
reconstruct as closely as possible in alignment and materials minimizing
the amount of hard area;
d.Provide details of connection points between the porch at Cottage 100
and the pavilion;
e.Investigate alternatives to replacement of east window at 100 Clematis
Dr. –if replacement is necessary, the original sash should be stored and a
new wood window installed in existing frame;
f. Consider installing interpretive signage that explains the history of the of
the pavilion and identifies the building as a reconstruction;
g. Submit details of all framing, roofing, railings, flooring including materials
and proposed finishes for review by the LDRC.
