March 5, 2018 Page 2 of 6 Report No. HAC18-004
Background
Location
The subject property is located on the east side of Machell Avenue between Wellington
Street East and Irwin Avenue (see Attachment 1). The property is currently listed and
non-designated on the Aurora Register of Properties of Cultural Heritage Value or
Interest and can be described as a 2 storey Ontario House.
Existing Policy Context
Ontario Heritage Act
The Ontario Heritage Act provides municipalities the ability to protect significant Cultural
Heritage Resources within its jurisdiction. Conservation measures under the Ontario
Heritage Act are outlined in Section 33 of the Act:
33. (1) No owner of property designated under section 29 shall alter the property
or permit the alteration of the property if the alteration is likely to affect the
property’s heritage attributes, as set out in the description of the property’s
heritage attributes that was required to be served and registered under
subsection 29 (6) or (14), as the case may be, unless the owner applies to the
council of the municipality in which the property is situate and receives consent in
writing to the alteration
Municipal processes within the Town of Aurora require the owner to submit a Heritage
Permit application should a request to alter the property under Section 33 of the Ontario
Heritage Act be requested by the owner. Approval of a Heritage Permit is provided
either by Council or through staff (via delegation By-law 5365-11).
Provincial Policy Statement (2014)
The Provincial Policy Statement (PPS) provides policy direction on matters of provincial
interest. The PPS identifies that significant built heritage resources and significant
cultural heritage landscapes shall be conserved.
York Region Official Plan
The York Region Official Plan requires local municipalities to conserve significant
cultural heritage resources and ensure that development and site alteration of adjacent
Heritage Advisory Committee Meeting Agenda

March 5, 2018 Page 3 of 6 Report No. HAC18-004
lands to protected heritage properties will conserve the heritage attributes of the
protected heritage property.
Official Plan
Section 13 of the Official Plan outlines the policies for conserving Cultural Heritage
Resources in the Town of Aurora. The Official Plan states that all significant heritage
resources shall be designated as being of cultural heritage value or interest in
accordance with the Ontario Heritage Act to ensure effective protection and their
continuing maintenance, conservation and restoration. Evaluation Criteria for assessing
the cultural heritage value will include: the aesthetic design or physical value; the
historical or associative value; and/or the contextual value of the property. Furthermore,
the plan states that heritage resources will be conserved in accordance with the
Standards and Guidelines for the Conservation of Historic Places in Canada, the
Appleton Charter for the Protection and Enhancement of the Built Environment and
other recognized heritage protocols and standards.
Analysis
Attachment #2 provides a summary of the Architectural, Historical and Contextual value
of 19-21 Machell Avenue. The proposed Statement of Cultueal Heritage Value or
Interest is provided below:
Built circa 1885; the John van Nostrand house is an early example of a purpose
built semi-detached structure constructed in Aurora in the late 19th century. 19-
21 Marchell is a 2 ½ storey brick structure with a cross gable roof, peaked centre
gable and clad in brick. The building is designed in an Ontario Gothic Revival
Architectural style with influence of Italianate design.
The house is associated with Mr. John van Nostrand, who was a timber lot and
sawmill owner in Vandorf, east of Aurora. Mr. van Nostrand (and later his estate)
tenanted the home during his 70-year ownership. One notable tenant was
Matthew Hind Thompson who was the first Principal of Church Street School,
lived in the home with his family between 1890 and 1909.
19-21 Machell Avenue is prominently located midway along Machell Avenue in
the vicinity of other historic homes. This house and others nearby help to create
a sense of heritage character in this part of Old Aurora.

March 5, 2018 Page 4 of 6 Report No. HAC18-004
Heritage Building Evaluation
The purpose of the Heritage Building Evaluation is to identify the design/physical value,
historical/associative value, and contextual value of the property as per Ontario
Regulation 9/06, which outlines the criteria for determining cultural heritage value or
Interest under the Ontario Heritage Act in order to conserve significant heritage
resources.
The Evaluation Working Group met to perform an objective evaluation of the subject
property on Wednesday February 14, 2018 (See Attachment 3). The Evaluation Criteria
for assessing the cultural heritage value of cultural heritage resources have been
developed by the Town in consultation with its Municipal Heritage Committee. As per
Section 13.3 e) of the Official Plan, Priority will be given to designating all Group 1
heritage resources in the Register.
The Evaluation found the subject property to score in the high end of Group 2,
suggesting that the property is “significant, worthy of preservation”.
According to the Heritage Evaluation Guide for buildings scored within Group 2:
• The designation of the building pursuant to the Ontario Heritage Act will be
encouraged;
• The retention of the structure in its existing location is encouraged;
• Any development application affecting such a structure should incorporate the
identified building; and
• Appropriate alternative uses for the building will be encouraged when necessary
to ensure its preservation.
• A Letter of Credit may be required to ensure the protection and preservation of
the building in connection with a redevelopment application.
The Ontario Heritage Act provides criteria for determining cultural heritage value or
interest with Ontario Regulation 9/06. This Regulation requires that a building must
exhibit significant design/physical, or associative, or contextual value to warrant
designation. The Evaluation working group found the final weighted score for 19-21
Machell Avenue to be 69.5/100. It is noted that a score of 70/100 would meet the
minimum threshold of Group 1.

Town of Aurora
Heritage Advisory Committee Report No. HAC18-005
Subject: Additional Information: Request to Remove a Property from the
Aurora Register of Properties of Cultural Heritage Value or Interest
14452 Yonge Street
Prepared by: Jeff Healey, Planner/Heritage Planning
Department: Planning and Development Services
Date: March 5, 2018
Recommendation
1.That Report No. HAC18-005 be received; and
2.That the Heritage Advisory Committee recommend to Council:
a)That 14452 Yonge Street be removed from the Aurora Register of
Properties of Cultural Heritage Value or Interest; and
b) That a financial contribution of $75,000.00 be provided to the Town’s
Heritage Reserve Fund;
Executive Summary
The purpose of this report is to provide Council with direction from the Heritage Advisory
Committee regarding the request to demolish all buildings and structures located at
14452 Yonge Street. The property is currently Listed on the Aurora Register of
Properties of Cultural Heritage Value or Interest.
•The house on the subject lands was constructed circa 1930
•The Heritage Evaluation Working Group re-evaluated the property. The property
remains in in the low end of Group 2 despite receiving a lower score.
Background
In August 2016, the owner submitted a Plan of Subdivision, a Plan of Condominium and
a Zoning By-law Amendment to the Town for the subject lands. The owner is proposing
to construct 40 residential lots on the west half of the lands. On February 13, 2017 the
Heritage Advisory Committee reviewed the request to remove the property from the
Heritage Registrar and proved the following recommendation to Council:
Heritage Advisory Committee Meeting Agenda

Item 2
Page 1 of 17
March 5, 2018 Page 2 of 5 Report No. HAC18-005
1. That Report No. HAC17-002 be deferred; and
2. That the Heritage Advisory Committee recommend to Council: (a) That a
structural report and re-evaluation of the property be brought back to a future
Heritage Advisory Committee meeting.
In February 2017, the owner has submitted a preliminary structural investigation for the
main building, prepared by Delvin Engineering and has requested that the main building
be re-evaluated by the Heritage Evaluation Working Group.
Analysis
The Evaluation Working Group met to re-evaluate the subject property on Wednesday
February 14, 2018 (See Attachment 5).
The Evaluation Working Group considered the submitted structural report, and changed
the Physical Condition category from “Good” to “Fair” as it was determined that the
exiting building is not structurally compromised, however requires a moderate amount of
structural repair.
It is noted that the first evaluation by the Evaluation Working Group in October 2016
was conducted prior to the site visit which occurred in January 2017. With the site visit
taken into consideration, the Design category was adjusted from “Excellent” to “Good”.
The fieldstone exterior finish is a stone facing rather than a true stone structure.
Although the building remains a rare example of the bungalow architectural style within
Aurora, the building does not exhibit a high degree of craftsmanship or design.
Finally the Evaluation Working Group reviewed the Architectural Integrity category and
determined that a change in scoring was not necessary. Although a number of dormers
and a 2nd floor balcony have been installed on the building, it would be relatively simple
to remove these features if the building was to be restored to an original state.
The conclusion of the re-evaluation found the subject property to score at the low end of
Group 2, suggesting that the property is “significant, worthy of preservation”.
According to the Heritage Evaluation Guide for buildings scored within Group 2:
• The designation of the building pursuant to the Ontario Heritage Act will be
encouraged;
• The retention of the structure in its existing location is encouraged;
Heritage Advisory Committee Meeting Agenda
Monday, March 5, 2018
Item 2
Page 2 of 17
March 5, 2018 Page 3 of 5 Report No. HAC18-005
• Any development application affecting such a structure should incorporate the
identified building; and
• Appropriate alternative uses for the building will be encouraged when necessary
to ensure its preservation.
The conservation of remaining physical attributes of the property would require formal
designation under Part IV of the Ontario Heritage Act, making it necessary for owners to
obtain Heritage Permits for proposed work.
The Ontario Heritage Act provides criteria for determining cultural heritage value or
interest with Ontario Regulation 9/06. This Regulation requires that a building must
exhibit significant design/physical, or associative, or contextual value to warrant
designation. The Evaluation working group found the revised final score for 14452
Yonge Street to be 46.6/100. The original final score was 51.8/100.
Proposed Concept Plan
The owner did not provide a composite drawing as part of the previous report to the
Heritage Advisory Committee. The owner has provided two composite models of a
home proposed to be built in place of the existing building on the subject lands. A
picture of the model home is shown on Attachment #6.
Staff have requested that a financial contribution to the Town’s Heritage Reserve Fund
be provided in the related Subdivision Agreement.

building within the proposed plan of subdivision.
Conclusions
The subject building was evaluated using the Town of Aurora Heritage Building
Evaluation Guide and was rated in the low end of Group 2, which encourages the
retention of the building as well as designation under the Ontario Heritage Act. Staff
recommend the Heritage Advisory Committee remove of 14452 Yonge Street from the
Aurora Registrar of Properties of Cultural Heritage Value or Interest.

Background
The Town’s Parks Division staff was approached by LSRCA staff in February 2017 to
discuss a project initiative LSRCA had for the removal of two (2) barriers along the East
Holland River that would allow for fish passage and increased habitat. The project
would connect an upstream tributary length of 5,500m to a downstream section of
7,400m resulting in nearly 13km of the East Holland River tributary being reconnected.
Parks Division staff had also identified both crossings for capital work funding. The
upstream crossing (Site1) consists of two steel 36” culverts, insufficient in diameter to
deal with flow demands during storm conditions, causing overland flooding to pedestrian
path and surrounding forest. As well, the culverts are obstructed with silt and debris.
The downstream crossing (Site 2) is a concrete culvert with historical association to the
former saw mill founded by the Lloyd family and has been identified to have significant
structural integrity concerns.
Staff recognized the value of this proposed partnership with LSRCA and the benefits
this project would bring to the health of the tributary and the added experience to
residents utilizing the Tim Jones and Klaus Wehrenburg trail systems. It was also
acknowledged that this project would be a great opportunity to replace the insufficient,
aging infrastructure.
Analysis
LSRCA’s proposal to remove fish barriers will increase habitat and range of
spawning for Brook trout and other species
LSRCA identified two (2) areas for restoration in close proximity of each other south of
Sheppard’s Bush Conservation Area. LSRCA has monitored the fish population along
this stretch of the East Holland River and has supporting data that indicates a healthy
population of Brook Trout, as well as other species such as Mottled Sculpin, Creek
Chub, Fathead Minnow and Brook Stickleback. All species would significantly benefit
from the project of removing the stream barriers and restoration of habitat, as it would
reconnect many kilometers of the East Holland River.

Impact of localized flooding on trail use and fish habitat reduced
Site 1 and Site 2 are both prone to overland flooding during heavy rain events and
spring thaws. The increased flow cannot be handled by the culverts at both locations
due to insufficient culvert capacity, degraded infrastructure, silt and debris. This causes
severe flooding of the trail system which inhibits recreational use by residents and
causing sever scouring, increasing maintenance for Parks staff in order to keep trail
safe for use. As well the trail surface material migrates both into the forest and stream
with the flooding affecting the woodland plants and fish habitat.
The redesign of these crossings, removal of culverts and installation of bridges will allow
for greater flow of water, significantly minimize the negative effects on the woodlands
and fish habitat and improve conditions for trail users.
Site 2 concrete box culvert constructed in early 1900’s with structural integrity
issues to be replaced with bridge.
In 2015 the Town of Aurora, Engineering Department retained Safe Roads Engineering
(SRE 2015) to assess 29 structures owned and operated by the Town of Aurora.
Included in this assessment was the concrete box culvert (Site 2) that carries the East
Holland River under the Tim Jones Trail. This report identified various deficiencies from
erosion and age, emphasizing wide cracking exacerbated by vegetation growth. A
recommendation was made that vehicle loading should be avoided, as the culvert was
past the point of economical rehabilitation or maintenance. SRE recommended the
structure be completely replaced.
As part of LSRCA’s East Holland Tributary Barrier Removal and Restoration Request
for Proposal, a heritage impact assessment was completed by ASI Archaeological and
Cultural Heritage Services (ASI) with respect to the concrete box culvert. The report
evaluated the cultural heritage significance of the East Holland River culvert and
assessed the impacts of the proposed project to remove and reconstruct the crossing,
while considering the cultural heritage value. The culvert was constructed in the early
twentieth century as part of the former mill founded by the Lloyd Family.
It was found that based on archival research, analysis of culvert design and design in
Ontario, site investigation and heritage evaluation, the culvert was determined to retain

Item 3
Page 3 of 70
March 5, 2018 Page 4 of 7 Report No. HAC18-006
cultural heritage value under Regulation 9/06 of the Ontario Heritage Act, and therefore
could be considered for municipal designation.
ASI presented a number of recommendations and mitigation measures for LSRCA and
The Town of Aurora to take into account, seeing the cultural heritage value of the
culvert. All options were given consideration but due to the structural integrity concerns
with the existing culvert, associated capital costs and long term infrastructure demands,
the preferred option is to remove and replace the culvert with a steel span bridge,
salvaging the culvert for display opportunities adjacent to the stream.
Natural environment improvements and cultural heritage aspects of former
sawmill founded by the Lloyd family will be promoted through education and
awareness
Elements of the culvert will be salvaged and incorporated into a display along the trail
adjacent to the stream, highlighting the heritage value of the culvert, the Lloyd family
lands and associated saw mill operations.
There is proposed to be interpretive signage that will link the former structure both
physically and functionally to its surroundings with respect to the milling practices by the
Lloyd family on the property, which began in the late nineteenth century.
The salvaged components of concrete culvert are interesting in that they have exposed
saw blades imbedded in the concrete, which will be showcased under a protective
barrier allowing for safe viewing by the public. In some retrospect the cultural heritage
of the structure will be better understood and recognized as the public cannot see these
interesting features as they are contained within the culvert as it exists currently.
LSRCA and the Town plan to include community groups in the planting of vegetation as
part of the restoration works, while promoting education and awareness of the natural
environment improvements of increased fish habitat, spawning sites and stream
rehabilitation.
The display and interpretive signage describing both the heritage value and attributes to
the natural landscape will significantly add to the trail system experience of users.
LSRCA will fund design, and ensure funding is allocated for construction and
contract administration with Town of Aurora supplying bridges

Lake Simcoe Region Conservation Authority will fund managing the design and ensure
finding is allocated for construction to remove and retrofit the two (2) stream crossings
along the East Holland tributary.
Town staff will review, comment and approve the work completed by LSRCA as key
stakeholders in the project. The Town will also supply the two (2) bridges to replace the
culverts at both Site 1 and Site 2, utilizing funding from approved capital budget for
bridges. The Town, as the owner of the lands and infrastructure, will be responsible for
the maintenance in perpetuity.
The Town benefits from this project by receiving retrofitted crossings that will improve
the flow of water and trail conditions by reducing frequency and severity of flooding;
increasing aquatic habitat; enhancing woodlands; improving aesthetics of crossings and
showcasing the cultural heritage of the area.
Timeline of the works to be completed in first quarter of 2019
If approved by Council, LSRCA provides following timeline for the works:
• Finalization of detail design package – 2018;
• Permits approval – March 2018 (incl. MNRF, DFO, & LSRCA)
• Tender for construction –May 2018
• Construction to commence – September 2018
Removal of crossings, in water works and bridges are to be installed during early winter
of 2018-2019 as trail use is minimal and conditions ideal for construction. Anticipated
timing for this work is approximately 6 weeks for both crossings. Project will be
completed with vegetative planting involving community groups occur in spring 2019.
