S E C T I O N 1

1.1 PURPOSE OF THE URBAN DESIGN BRIEFThe proposed Graydon-Banning Ltd./Martillac Estates Inc. (herein referred to as Graydon/Martillac) community development is located in the south-central limit of North Oakville and forms a component of the broader North Oakville Secondary Plan Area. The Graydon-Banning/Martillac (North Oakville) Urban Design Brief is submitted as a component of the development application. It collectively provides design direction for the implementation of the vision and intent of the two subdivision communities and serves as a supplement to the Town of Oakville’s ‘parent’ design guidelines document, the North Oakville Urban Design and Open Space Guidelines (Brook McIlroy, November 2009). The Urban Design Brief focuses on the physical design of the community, with particular reference to structuring elements, the major road network, Natural Heritage System, stormwater management (SWM) pond, Village Squares, employment lands and residential areas (General Urban, Neighbourhood Centre, High Density and the Dundas Urban Core areas). It will prescribe open space and built form guidelines and principles for these areas and components, while allowing some flexibility for delivering a wide range of design expressions, architectural form and styles that provide interest in the urban environment. The Urban Design Brief emphasizes and details the integral elements that will help create an innovative, walkable, transit-friendly environment with mixed residential densities and commercial opportunities. It is noted that the timing of development of the neighbouring CHWO lands is unknown and, as such, the CHWO lands have not been considered in this document.

1.2 STUDY AREAThe Graydon/Martillac study area consists of a combined 30.6 ha. of land (Graydon Banning - 24.1 ha./Martillac - 6.5 ha.) and is bounded to the north and east by the Sixteen Mile Creek Natural Heritage System (NHS), to the south by Dundas Street West, and to the west by future development and the Glenorchy Conservation Area.

1.3 COMMUNITY GOALS AND OBJECTIVESThe Graydon/Martillac development area is planned as a component of a model urban community and is designed to be an integral part of the larger communities of North Oakville, the Town of Oakville and Halton Region. In order to achieve this, the following community goals and neighbourhood objectives have been established:

1.3.1 Community Goals• To create a sustainable natural and open space system - recognizes the

importance of the natural environment and the established NHS within and surrounding the Graydon/Martillac study area, and the need to protect and capitalize on these existing resources to benefit future generations.

• Provide access and visibility to open space - recognizes the importance of developing physical (interconnected trail system, street network) and visual access to open spaces; these spaces are supportive of an improved quality of life and promote physical activity by providing recreational opportunities for residents.

• To create a sustainable transportation network - recognizes the importance of intensifying land uses in specific areas, such as within the Dundas Urban Core, Neighbourhood Centre Areas and the High Density Residential Area, to support the use of transit and reduce the length of vehicular trips.

• To create compact, walkable mixed-use development - recognizes the importance of creating walkable, pedestrian-scaled neighbourhoods through public and private realm design initiatives that encourage community interaction and fosters a sense of place for the Graydon/Martillac neighbourhoods and surrounding North Oakville development areas.

• To encourage a variety of housing - recognizes the importance of implementing a variety of housing types, styles and densities that contribute to the character of distinct neighbourhoods.

• To preserve and extend residential enclaves and cultural heritage - recognizes the importance of creating well-planned neighbourhoods that promote the character of the site, contributing to a unique sense of place.

• To provide a vital setting - recognizes the role of mixed-use buildings, especially within the Urban Core along Dundas Street West, to provide a community-wide focus for residents.

1.3.2 Neighbourhood ObjectivesA set of key neighbourhood objectives has been established as part of the Graydon/Martillac study. These are summarized as follows: • Dundas Street West - this area will potentially be characterized by medium-

density/condominium residential uses with opportunities for mixed commercial-residential use. This higher-density built form, along with community gateway entrances within adjacent lands to the east and west, shall serve to reinforce the integration and prominence of Dundas Street West.

• Neighbourhood Centre - create opportunities for greater residential density along ‘main streets’ within the community.

• Transit Supportive Development - create a pedestrian accessible environment using a modified grid street pattern with minimized block lengths that enable residents to be in close proximity to bus transit stops.

• Streets - a street configuration that provides logical, safe and convenient access to community facilities and natural features within and beyond the study area.

• Natural Heritage and Open Space System - Graydon/Martillac shall protect and enhance the NHS and open space system by providing visually and physically interconnected open spaces throughout all neighbourhoods.

• Trail Network - establish path and trail connections within Graydon/Martillac that are an integral link for the comprehensive North Oakville trail network.

• Village Squares - integrate important open space facilities that provide active and passive uses, a variety of functions and features, and serves as a social and recreation focus for residents.

• Integration - ensure the physical fabric and land uses within Graydon/Martillac integrate appropriately with adjacent existing and future land uses.

• Diversity - the Dundas Urban Core, Neighbourhood Centre and mixed residential densities within Graydon/Martillac and surrounding lands provide a range of housing opportunities within close proximity of community amenities (transit, parks, schools, trails and natural features).


1.3.3 Surrounding Land UsesLands surrounding the Graydon/Martillac study area provide structure and influence the block pattern and street layout for the proposed community, consistent with the North Oakville East and West Secondary Plan. Specifically, to the north and east (beyond the adjacent CHWO lands) is the Sixteen Mile Creek Natural Heritage System valleylands, to the west is the Glenorchy Conservation Area (Conservation Halton), as well as the potential for future planned employment lands (Oakville Green health/life sciences development), and to the south (south of Dundas Street West) is existing residential lands and community facilities (St. Volodymyr Cultural Centre, community park and recreation facilities, schools). The identified CHWO lands to the east are not being developed or considered at this stage.

1.3.4 Development SummaryLand uses proposed for the two subdivisions, namely Graydon Banning Ltd. and Martillac Estates Inc., are collectively planned as a mix of residential densities, including single detached dwellings, townhouse dwellings (front and lane-accessed), as well as higher density/condominium built form associated with the Dundas Urban Core Area fronting onto Dundas Street West and High Density Residential blocks situated in the north-east and central west areas of the subject lands. Other land uses include portions of proposed Employment lands in the south-west, as well as Village Square’s, a stormwater management pond facility and the interface with the designated NHS in the south-west, north and east edges of the study area. Identified CHWO lands immediately adjacent to the east do not form a component of the Urban Design Brief, although the UDB will demonstrate proposed development fabric. Access into the study area is provided from the south by a north-south road connections with Dundas Street West. A future connection will be provided within the CHWO lands. As well, an east-west link of the future William Halton Parkway, an arterial road connection located at the mid-point of the study area, will provide access from the east and west sides of the community area. Generally, the proposed plan of subdivision has higher densities near Dundas St. West (Dundas Urban Core) and adjacent to the proposed William Halton Parkway (Neighbourhood Centre and High Density Residential Block). A mix of lower and medium density residential (General Urban) is located between the designated Neighbourhood Centre and Dundas Urban Core areas. General Urban continues north of the Neighbourhood Centre, consisting primarily of lower density residential.

The two proposed Village Square’s have been situated to enable safe, walkable access from all areas of the community, with each representing the focus of the surrounding neighbourhoods. The Village Square’s are intended to accomodate active and passive uses, with supporting amenities and facilities. Employment lands are situated in the south-west corner of the study area, west of the NHS corridor and bisected by the Avenue/Transit Corridor connection with Dundas Street West. This land designation functions as an extension of the planned employment lands to the west, consistent with the North Oakville West Secondary Plan. As indicated, these employment lands are planned for a future health/life sciences development, which will be directly linked with the Avenue/Transit Corridor road within Graydon/Martillac. The proposed development recognizes and preserves existing NHS features, while integrating views, vistas and multi-use links through the open space features and trail network.

1.4 PLANNING AND URBAN DESIGN POLICIESThe proposed Graydon/Martillac community is subject to several planning studies and processes. This Urban Design Brief outlines a set of guidelines consistent with the objectives of the following documents:

North Oakville East Secondary PlanThe North Oakville East Secondary Plan establishes detailed planning objectives to guide future development in the area. It also outlines the conditions which must be met prior to any development proceeding. The proposed development plan recognizes Oakville’s distinctive historical roots and small-town heritage, while creating a compact, pedestrian-oriented urban community that offers a broad range of housing opportunities. The character and pattern of the community recognizes and preserves natural heritage features, integrating views, vistas and pedestrian systems. A range of housing types and densities are proposed, accessible to transit and within walking distance to activities and amenities.

North Oakville Master PlanThe design and structure of Graydon/Martillac complies with the North Oakville Master Plan (Appendix 7.3 - February 2008), which graphically illustrates the structuring elements, land uses and overall design of the North Oakville Planning Area and sets out the manner in which the policies and figures of the Secondary Plan are to be implemented.

North Oakville Urban Design and Open Space GuidelinesThe North Oakville East Urban Design and Open Space Guidelines outline the physical design components necessary for the development of a high quality, sustainable and integrated community. They provide a detailed set of objectives, illustrated recommendations and guidelines that will greatly expand the Town’s capacity for urban living, employment and recreation, by implementing the broad policies of the North Oakville East Secondary Plan. Individual development applications must be evaluated according to relevant urban design principles and open space guidelines.

North Oakville East Trails PlanThe North Oakville East Trails Plan Presentation (Presentation to Subcommittee, February 2012) outlines the Conceptual North Oakville East Trails Network, as part of the Town’s objective of developing a functional transportation system that recognizes all modes of transport. Implementation of the trails plan is regulated through submission of subdivision applications.

North Oakville Sustainability ChecklistThe North Oakville Sustainability Checklist is an important tool for assessing the sustainability of planned developments. Based on North Oakville Secondary Plan policies, the checklist is meant to be a tool to encourage sustainable development practices.

North Oakville Urban Forest Strategic Management PlanThe North Oakville Urban Forest Strategic Management Plan is a high level strategy and planning study prepared to provide the Town of Oakville with recommendations and guidelines for achieving a sustainable, healthy urban forest for the North Oakville lands. This strategy is an extension of the Town’s long term vision to achieve its 40% tree canopy coverage target.

2.1 SITE DESIGN AND LAND USESThe Graydon/Martillac community will incorporate a mix of land uses that will define the character and function of the neighbourhoods. These uses include: • General Urban - predominantly single-detached dwellings with potential for

semi-detached and townhouse units.

• Neighbourhood Centre Area - predominantly townhouse dwellings with potential for live/work units, retail and/or community facilities/services;

• Dundas Urban Core - medium-density/condominium residential, potentially including front and rear loaded townhouses, back-to-back townhouses and low, mid or high rise apartments and potential for retail and/or community facilities/services;

• High Density Residential - medium-high density residential, including front and rear loaded townhouses, back-to-back townhouses and low-mid storey apartments;

• Employment Area - serves as an extension of the Employment lands designated for the North Oakville West Secondary Plan;

• Stormwater management pond;

• Natural Heritage System - corridor extending from the Glenorchy Conservation Area in the south-west corner of the development lands. A pocket of NHS lands (Sixteen Mile Creek) integrated along the east perimeter, with the north perimeter defined by NHS buffer lands;

• Village Square’s - strategically located within walking distance to function as the neighbourhood recreation focus and social gathering space.

Single detached residential shall comprise a significant portion of the land area north of William Halton Parkway. These will be typically front-loaded dwellings with front elevations and driveways accessed from the local street network. Beyond the proposed low-density residential, the Dundas Urban Core, Neighbourhood Centre Area and High Density Residential area will largely define the identity of the community and, along with the Village Squares, SWM Ponds and NHS, will encompass the character areas described in the following sections.

2.2 STRUCTURING ELEMENTSThe structuring elements for Graydon/Martillac will serve as the main building components for delineating the various land uses, establishing the street hierarchy network and providing the framework of neighbourhood areas. Although the following section is of premature nature, it describes these key structuring elements for the future community.

2.2.1 Road HierarchyThe overall framework for the community is defined by the Dundas St. West (south extent) arterial corridor, as well as the configuration of local and collector roads that will link future residential, mixed-use development with open space amenities and transit facilities. The proposed road hierarchy within the Graydon/Martillac lands will consist of the following street types (refer to Fig. 2.1.2a): • Laneway - 7.5m-11.0 R.O.W./Dundas Urban Core, General Urban Area, and

High Density area/2 travel lanes/paved apron on both sides;

• Local Road - 17.0m R.O.W./transportation corridor and neighbourhood social focus/2 travel lanes/on-street parking on one side/4.05m boulevard;

• Connector/Transit Corridor - 19.0m R.O.W./connector and potential transit link/serves lower volumes of intra-neighbourhood travel/ 2 travel lanes/1 parking lane/4.55m boulevard;

• Avenue/Transit Corridor - 22.0m R.O.W. – General Urban Areas/connectors and potential transit links/alternative routes for access to Neighbourhood Centre and Dundas Urban Core/access to major land uses/2 travel lanes/on-street parking on both sides/4.55m boulevard;

• Arterial/Transit Corridor - Dundas St. West and William Halton Parkway/major transportation function/town-wide transit connections/access to major land uses.

The proposed street network within Graydon/Martillac strives to balance pedestrian, cycling and vehicular functions within a compact, urban street right-of-way. The following describes some of the proposed streetscape elements associated with each proposed roadway type.

Fig. 2.2.1.1 - Laneway - 7.5m R.O.W./2 travel lanes/paved apron.

2.2.1.1 LanewaysLaneways reflect a traditional urban form that benefits the parallel local street environment in many ways. Lane-based townhouse dwellings may be integrated as part of the street network to provide an urban front door interface with the local street, achieve variation in the built form product and enable some efficiencies in block layout to achieve a more compact urban village environment. As well, lanes reduce interruptions to the street curb edge, resulting in the minimizing of driveways and allowing for continuous rows of street trees with a larger rooting area. The following describes some of the proposed streetscape elements: • Shall allow for 2-way vehicular travel with a paved apron on both sides.

• Apron provides potential to locate utilities to the rear of dwellings and away from the local street right-of-way.

• The appearance of the lane should be enhanced through thoughtful design and selection of the garage, garage door and any fencing details.

• The entry to the lane should be landscaped with grass, trees and shrubs where appropriate to enhance the streetscape perpendicular to the lane.


2.2.1.2 Hybrid Local Roads• 11.0m right-of-way that allows for 2-way vehicular trabel with sidewalks on

both sides.

• Lane widths shall reflect minimum standards to facilitate slower traffic speeds and a safer, more comfortable pedestrian and cycling environment.

• Proposed within the Dundas Urban Core, which is characterized by front-loaded townhouse, back-to-back townhouse and low-mid storey apartments.

• Street trees will predominantly be situated within the private front yard of the townhouse dwellings.

• Street trees shall consist of coarse textured, primarily native street trees.

• Planting conditions, such as appropriate soil volumes and rooting area, shall promote long term growth of street trees.

• All planting shall be in accordance with the North Oakville Urban Forestry Strategic Management Plan.

• Street light poles and luminaires shall reflect approved Town standards.

Fig. 2.2.1.2a - Hybrid Local Road - 11.0m R.O.W./2 travel lanes/sidewalk on both sides.


2.2.1.3 Local Roads• 17.0m right-of-way with minimum 1.5m sidewalks on both sides.

• Shall allow for 2-way vehicular travel with on-street parking on one side.

• Consists of a 4.05m boulevard, with a tree planting zone width (edge of sidewalk to inside curb) of 2.25m.

• Street trees will generally be located within the public grass boulevard between sidewalk and curb.

• Street trees within private front yards are encouraged to supplement the tree canopy coverage, providing a more shaded sidewalk and attractive streetscape appearance.




Fig. 2.2.1.3 - Local Road - 17.0m R.O.W./2 travel lanes/on-street parking on one side/4.05m boulevard.


Fig. 2.2.1.4 - Connector/Transit Corridor - 19.0m R.O.W./2 travel lanes/on-street parking on one side/4.50m boulevard.

2.2.1.4 Connector/Transit Corridor• 19.0m right-of-way which serves as a primary north south link through the

Graydon/Martillac community, connecting Dundas St. West with William Halton Parkway to the north.

• Shall allow for 2-way travel with dedicated on-street parking on one side.

• Consists of a 4.55m boulevard, with a tree planting zone width (edge of sidewalk to inside curb) of 2.55m. Where a bus transit stop is located, the 2.55m width shall be hard surfaced to accommodate transit-related facilities such as a bus shelter, bench, waste receptacles, newspaper boxes, etc.

• Minimum 1.5m sidewalks provided on both sides.

• Given the residential and open space interface, street trees will generally be situated within grass boulevards, between sidewalk and curb.

• Pedestrian crossings at key intersections shall be installed with enhanced paving or pavement markings as an attractive feature and to reinforce a safe, walkable environment.






It should be noted that in the interim there will not be a connection to Dundas Street West, as that portion lies within the CHWO lands. An interim land configuration will connect William Halton Parkway to the limit of Martillac lands and CHWO and connect west to the rest of the neighbourhood.

2.2.1.5 Avenue/Transit Corridor• 22.0m right-of-way which serves as a primary entry point into the community,

extending from Proudfoot Trail south of Dundas St. West towards William Halton Parkway to the north.

• Shall allow for 2 travel lanes with dedicated on-street parking on both sides.

• Consists of a 4.55m boulevard, with a tree planting zone width (edge of sidewalk to inside curb) of 2.55m. Where a bus transit stop is located, the 2.55m width shall be hard surfaced to accommodate transit-related facilities, such as a bus shelter, bench, waste receptacles, newspaper boxes, etc.

• Minimum 1.5m sidewalks provided on both sides.

• Given the employment, NHS and open space interface, street trees will generally be situated within grass boulevards, between sidewalk and curb.

• Apart from bus transit locations and where appropriate to the adjacent land use type and function, a more urban boulevard condition may be considered. This generally provides a greater extent of paving to facilitate increased pedestrian traffic and easier access from curb-side parked cars. It also provides more flexible space to integrate outdoor furniture.

• Urban boulevard conditions shall consider urban tree planting technologies (modular and aggregate suspended pavement systems, tree grates, raised planters) that are conducive to heavy pedestrian traffic, while achieving appropriate soil volumes.

• Pedestrian crossings at key intersections, with enhanced paving or pavement markings, shall be installed as an attractive feature and to reinforce a safe, walkable environment.

2.2.1.6 Arterial/Transit CorridorsAs Arterial/Transit Corridors, Dundas St. West and the future William Halton Parkway (Regional Road) are main east-west transportation corridors for North Oakville East and serve as a key structuring element for the Graydon/Martillac community. William Halton Parkway will replace Burnhamthorpe Road’s regional road function and will be characterized by a mix of uses, potentially including high density residential, commercial, employment and public open space. Specific to Graydon/Martillac, William Halton Parkway will interface primarily with Neighbourhood Centre and High Density area land uses. The following describes some of the proposed streetscape elements: • Ultimately intended as a four to six lane road with off-peak on-street parking

on both sides.

• Sidewalks provided on both sides of the road, which, depending on adjacent built form use, may extend to the building frontage.

• Street trees situated within the boulevard may be planted in a grass strip or hard surface treatment (raised planter, tree grates), depending on adjacent built form use.

• Additional street trees may be planted within centre medians to frame the dedicated bus-way, provide greater canopy coverage and reduce the perceived scale of the road.

• Pedestrian crossings at key intersections will be installed with enhanced paving as an attractive feature and to reinforce a safe, walkable environment.




2.2.2 Natural Heritage System (NHS)The proposed Natural Heritage System (NHS), comprising a corridor extension from Glenorchy Conservation Area in the south-west corner, a pocket of lands integrated along the east perimeter and the north perimeter defined by NHS buffer lands, as well as substantial lands extending outside the Graydon/Martillac development area (Sixteen Mile Creek lands), is designed to ensure an ecologically diverse, healthy and sustainable NHS in an urbanized setting. The primary objective is to preserve the existing natural environment to achieve multiple objectives and targets related to fish and wildlife habitat, connected natural areas and features, community diversity, water management, etc., that will be balanced and implementable. The proposed land use fabric, including streets, residential, mixed-use, open space features and buffer elements, evolve from the prominent NHS lands and will provide important vista opportunities within walking distance of all neighbourhoods. As well, the street grid pattern will allow convenient and logical access to the proposed trail system integrated into these features. Land uses immediately adjacent to the NHS (woodlands, wetlands, watercourses) shall be designed to support the NHS features through careful integration of streets, public open spaces, trails, etc. and by establishing required setbacks and buffers.

2.2.3 Stormwater Management PondIn addition to its primary water quality and control function, a stormwater management (SWM) pond will be designed to maintain the environmental and ecological integrity of the NHS and to provide a net benefit to the environmental health of the development area, to the extent practical. A single SWM pond (1.75 ha.) is situated along the Dundas St. West frontage within the Graydon/Martillac study area to function as part of a comprehensive sub-watershed strategy. This pond has been located in relation to existing drainage patterns of the site and, given its proximity to the existing NHS corridor to the west, will augment the extent of the natural areas and provide viewshed opportunities to and through the NHS. The facility is designed to appropriately fit within the context of a mixed-use residential community. To encourage a strong connection with the community, the design of the pond shall have regard for the following: • A regular spaced row of coarse-leaved canopy trees shall be provided along

the street frontage in combination with areas of naturalized planting.

• The integration of lookouts shall be provided at the pond entry as a public amenity that may provide seating and decorative features (decorative paving, information signage, shade structure, formal planting) at desirable view opportunities along the street interface.

• Naturalized planting throughout to consist of whips, multi-stem shrubs, ornamental grasses and riparian, aquatic and upland species appropriate for the pond condition, with an emphasis on native species, in accordance with Conservation Halton standards.

• Pedestrian trails shall be integrated to provide connections from the street pond entry (from the Dundas Urban Core area) to adjacent NHS trail networks.

• Trails within the pond shall be combined with maintenance access roads in common locations to minimize non-vegetative surfaces, while facilitating important pedestrian linkages.

• Should utility structures be placed within the pond facility, they shall be screened from public view with planting and fencing or other built features, as necessary.

• Provide information signage at the pond entry/lookout area to inform the public of the importance and treatment of the stormwater management pond as a functioning natural open space feature.

• The design of the SWM pond shall require approval from the Town of Oakville, Conservation Halton and the Ministry of Environment.

The opportunity to design the SWM pond with a more urban, compact layout may be considered. Compared to conventional ponds, urban stormwater management ponds are characterized by terraced retaining walls along a portion of the perimeter rather than earthen slopes. Urban SWM ponds have the advantage of reducing the overall area required for pond development, while enhancing the public realm. In addition to guidelines for conventional SWM ponds, the following should be considered: • Opportunities exist to substantially terrace plant in between rows of

armourstone or other retaining wall system, effectively screening a large extent of the retaining wall, should that be desired, while providing a gradual and fully vegetated transition from water level to the street edge.

• Armourstone or its equivalent is an appropriate landscape treatment that provides an additional element and character to pond design. It can be layed out in a sinuous pattern to better integrate with the natural patterns of the landscape planting.

• Armourstone or other retaining wall system should be placed an appropriate distance from adjacent street right-of-ways so that it has no impact on the design, safety and support of the roadway.

• Dense planting should serve as a barrier between multi-use paths and retained sloped edges on the low side of the path.

• Armourstone or other retaining wall system should not be utilized below the regulatory storm event or in the path of the overland flow routes.

Fig. 2.2.3a - Conceptual image showing how urban pond edges can be formed with an armourstone retaining wall system.


2.2.4 Future Adjacent Residential CommunityThe future proposed residential development located adjacent to the east side of the Graydon/Martillac study area influences the structure and layout of the community through the continuation of the street network. As well, primary land uses and facilities, such as the Dundas Urban Core area (Condominium Block) and SWM pond are complementary to similar land uses proposed within the subject lands, combining to define the Dundas St. West character.

Fig. 2.2.3b - Conceptual images showing examples of conventional SWM ponds and how they can be designed to provide valuable community amenity features.


2.3 DUNDAS URBAN CORELocated along the Dundas St. West frontage, the 2.14 ha.

2.5 NEIGHBOURHOOD CENTRE AREANeighbourhood Centre Areas are ‘main street’ driven development areas that are typically characterized by varying degrees of residential density, with the potential for integrated retail or civic functions. They are largely distinguished by a low-rise built form type and use, with a strong focus on architectural treatment, open space and streetscape presence. Neighbourhood Centres play a key role in strengthening the urban structure and defining the character of surrounding neighbourhoods. They reflect an emerging typology within the Town of Oakville that strives to achieve an increase in the livability of new residential communities through an emphasis on the use of public transit and walkability, leading towards a more sustainable, functional and healthy environment.Consistent with the North Oakville East Master Plan, a Neighbourhood Centre Area (1.40 ha.) is planned for Graydon/Martillac, adjacent to the future William Halton Parkway and located central-west within the community. This Neighbourhood Centre Area shall be designed with the following objectives and parameters:

2.5.1 Built Form Guidelines• May typically comprise a combination of low-rise built form, including

townhomes (front or rear-loaded), with options for stacked townhouses, potential live/work units at key intersections and apartment dwellings up to 5 storeys.

• Built form shall have a strong orientation to the street with at grade entrances where feasible.

• Prominent building massing and architectural treatment shall be provided at the street edge to create street animation and enable access to dwellings and establishments from adjacent sidewalks.

• The potential for mixed use developments fronting on William Halton Parkway shall be considered.

• Building scale and architectural styles shall be provided in a manner that reinforces an attractive, active, human-scaled street environment and promotes an urban village main street character.

• Each building may reflect its own distinct architectural identity, although all buildings should be designed to provide a collective sense of cohesion and harmony.


Fig. 2.5.1 - Townhouse dwellings fronting onto the William Halton Parkway will be lane-accessed to avoid driveways fronting onto this future arterial road.


2.5.2 Open Space/Streetscape Guidelines• Boulevard treatment shall reflect adjacent building use. For example,

boulevards adjacent to single or semi-detached residential lots may be characterized by a grass boulevard with street tree placement between curb and sidewalk. Where at-grade retail functions are considered, such as live/work units, the boulevard may reflect a more urban treatment with hard surfaces for greater accessibility, street furniture and/or alternative street tree planting techniques.

• Where required by residential, retail or service-related uses, ensure provisions for accessible pedestrian connections from the street level are integrated into the boulevard design.

• Where it is deemed feasible and beneficial to adjacent land uses, strategically integrate lay-by or on-street parking allowances adjacent to retail and service related amenities. Where on-street parking is provided, curb extensions may occur at intersections in order to provide additional boulevard space.

• Where applicable, bus stop locations should be integrated with the streetscape treatment, including the sizing of shelters that are appropriate to the boulevard width, and respond to the street level uses of adjacent built form and driveway locations.

• Crosswalks at key intersections may be distinguished by an enhanced paving treatment.

• Street furniture, where considered, shall reflect current Town of Oakville standards, unless otherwise directed by the Town.

• Above-ground utilities shall be strategically located to mitigate negative visual impacts and minimize physical barriers to pedestrian flow.

Fig. 2.5.2 - Crosswalks at key intersections within the Neighbourhood Centre may be distinguished by an enhanced paving treatment.


2.6 EMPLOYMENT AREAThe Employment Area lands planned for the south-west corner of the Graydon/Martillac development area are an extension of the future employment uses planned within the lands immediately adjacent to the west. The potential proposed use is for the Oakville Green health sciences business park and campus, a mixed-use community intended for work, play, shop and live. Although the status of the application is unknown, if approved, the development is expected to include a medical centre, research incubator, hotel, conference facility, office buildings and high-storey residential towers, along with associated amenities and open spaces.The research and technology focused development shall incorporate the pertinent employment land use and site design strategies and guidelines described in the North Oakville Urban Design and Open Space Guidelines in achieving a ‘green’, sustainable and pedestrian friendly business park and campus that is strongly linked with the local and regional transit network. The framework for the development will be structured to enable connectivity with the Avenue/Transit Corridor and Proudfoot Trail to the east and south, thereby extending into the pockets of employment land found within the Graydon/Martillac community.


2.7 VILLAGE SQUARESTwo Village Square’s are proposed for the Graydon/Martillac community, with each serving as the primary focal and social space for the surrounding neighbourhoods. The north Village Square, with an area of 0.50 ha. (1.24 ac.), is situated central to the surrounding neighbourhood, with General Urban Residential land uses fronting or flanking on all sides. The south Village Square, with an area of 0.46 ha. (1.14 ac.) also has local road frontage on 3 sides and is adjacent to General Urban Residential (north and east), SWM pond (west) and Dundas Urban Core (south) land uses.Centrally located for convenient access by all residents, these parks provide an opportunity for a neighbourhood to distinguish itself through the use of a distinct palette of design elements and plantings, setting the tone and character of the place. As such, the Village Square’s will contribute a strong visual identity for each neighbourhood and complement access to the NHS trail network.The Village Square’s shall be designed with the following guidelines: • Provide both passive and active (playground) play opportunities at the local

or neighbourhood scale.

• Key features shall be sited to terminate view axes.

• Potential features may include junior and senior play structures, multi-use trail, shade structure and seating, formal entry and unprogrammed open space.

• Lighting should be provided for facilities and features, as required.

• The design of hard and soft landscape elements and features, including points of entry, should be consistent or complementary with neighbourhood themes (surrounding built form).

• Entry points shall be strategically located to ensure convenient and safe access.

• Shade structures and/or playgrounds should be designed as the primary focal elements for the park.

• Planting (trees, shrubs, grasses, perennials) shall comprise species tolerant of urban conditions with an emphasis on native species.

• Tree planting shall generally reflect an informal layout with cluster groupings contained within lawn areas to facilitate shaded passive use.

• Hard and soft landscape elements and features will be designed to identify areas of activity, circulation, entry points, seating and gathering areas.

• Provide reasonably level and functional open play areas for passive recreation use.

• Lighting shall be provided for facilities and pathways, as required.

• Since the property at 1361 Dundas Street West (Village Square B) is a listed heritage property for the remnants of the Shevchenko monument, the heritage value shall be incorporated into the proposed landscape design. As part of this commemoration, the proposed design may incorporate some of the salvageable stones into the future walkways as well as a commemorative plaque placed on the site.

Fig. 2.7a - Conceptual facility fit plan of the proposed north Village Square. Final park programming shall be determined at the detailed design stage, in concert with Town staff.


Fig. 2.7b - Conceptual facility fit plan of the proposed south Village Square. Final park programming shall be determined at the detailed design stage, in concert with Town staff.

Fig. 2.7c - Features proposed for the Village Square, such as the playground facility, shall encourage community gathering.

Fig. 2.7d - Village Square features, such as shade structures, shall be designed as the primary focal elements of the park.

Fig. 2.7e - The Village Square shall be designed for, both, passive and active recreation opportunities.


2.8 STREETSCAPE DESIGN AND GATEWAYSStreetscape design and treatment, and the integration of gateway features are significant elements in communicating the character of the Graydon/Martillac neighbourhoods, as an extension of the adjacent future residential lands. The following are some general guidelines that shall be considered in the design development of these components.

2.8.1 Streetscape Design GuidelinesReflecting the road hierarchy, the proposed streetscape treatment shall serve a functional and urban design role and is a primary component in establishing the urban village character of the Graydon/Martillac community. Although each road type will be characterized by a particular set of streetscape elements, the collective network of streets will project a complementary, distinct and cohesive image for the community. The following is a general description of the proposed streetscape treatment associated with each road type found within the study area:• Proposed streetscape treatment shall be appropriate to the street designation

as established through the proposed street hierarchy.

• Street trees shall be spaced to create an effective canopy and strong streetscape presence.

• Street tree species shall adhere to approved Town of Oakville specifications.

• Appropriate boulevard widths between sidewalk and curb shall be integrated into the right-of-way to promote healthy growing conditions.


• A double row of coarse-leaved street trees should be considered, specifically along Dundas St. West, to reduce the perceived scale of the road and provide an attractive interface between the road and the proposed built form.

• Streetscape design along local streets and portions of collector roads will typically comprise a single row of trees in grass boulevards between sidewalk and curb.

• Streetscape design within or adjacent to the Dundas Urban Core shall consider the integration of typically urban features to facilitate higher pedestrian traffic, retail/service functions and on-street parking. These features may include tree pit covers, street furniture, distinctive light standards, hanging flower baskets, banners, lay-by or on-street parking, enhanced crosswalk treatment, etc.

• All planting shall comply with the North Oakville Urban Forestry Strategic Management Plan.

Fig. 2.8.1 - Eaxmple of a successful streetscape treatment within a new Oakville neighbourhood that is attractive and encourages walkable connections.


2.8.2 GatewaysGiven the configuration of the proposed development area (including the adjacent CHWO lands) and the significant surrounding natural land uses, the Graydon/Martillac site can be considered a consolidated, well-defined residential community. As such, the identity and character of the community will, in part, be defined by the interface and primary access points between the community and the adjacent Natural Heritage System and Glenorchy Conservation Area, as well as Dundas St. West. Through a consistent design and material palette, the gateways are an effective tool in creating a sense of entry into a discernible, cohesive community. They are an important identifier that provides opportunities for branding as a reflection of the character and theme of the community. As well, they serve as effective way-finding markers from outside the community.

2.8.2.1 GatewaysThe following guidelines shall apply in the design of these features:• Gateways shall be defined primarily by adjacent built form orientation and

architectural treatment. Associated landscape features may be integrated to reinforce the gateway function.

• Gateways shall reinforce the character of the community through a complementary material palette that complements the prevailing architectural style and materials.

• Only robust, durable materials and design shall be considered, with minimal long term maintenance requirements.

• Gateways shall provide for safe, attractive and logical pedestrian entry into the community.

• All above ground utility boxes should be sited away from the gateway area when possible.

• Landscape treatment may consider a combination of various elements, including decorative paving, plantings, grass, and lighting.

• Plantings should consist of a limited variety of tree, shrub, grass and perennial species to minimize maintenance requirements.

2.9 TRAIL NETWORKThe North Oakville Secondary Plan calls for the development of an extensive recreation trail system. Consistent with the North Oakville Trails Plan, May 2013, the trails system proposed for the Graydon/Martillac study area will provide access to the NHS from the adjacent streets and SWM pond of the development. In doing so, the trail will connect to planned or existing pathways throughout the broader community as a comprehensive pedestrian linkage network. The following trail locations and types shall be integrated with this community:• William Halton Parkway - on-road bike lanes combined with off-road

(boulevard) multi-use trails;

• Dundas Street West - Regional bicycle facility, including multi-use trails;

• Natural Heritage System - major trail (multi-use, 2.1-2.4m width);

• Glenorchy Trail System - major trail (multi-use, 2.1-2.4m width);

• SWM Pond Trail - multi-use trail, combined with maintenance access.

The following guidelines shall apply:• The material composition of the trail shall be appropriate to the surrounding

natural features and anticipated type and frequency of use.

• Trails shall be sited to mitigate impacts to sensitive environment.

• Trails may vary in size to allow two-way cycling, based on Town standards.

• Trail lighting requirements shall be determined on a site-by-site basis and take into consideration issues related to night-time use, disturbance of natural areas, impacts on adjacent land uses, maintenance requirements, etc.

• Where feasible, trails should be accessible and visible from adjacent streets.

• Pedestrian trails shall be integrated into the NHS corridor buffer design, connecting with the SWM pond trail and adjacent street sidewalks to encompass the pedestrian and cycling network for the community.

• Where applicable, all trails shall be appropriately set back from adjacent residential rear lot lines.

• Trail design elements may include trailhead markers, seating areas and information signage for way-finding and community/Regional cycling network.

• Trails located within natural features shall be linked with other pedestrian and cycling pathways and connections, in order to achieve a comprehensive, interconnected pedestrian and cycling network.

The built form component proposed for Graydon/Martillac shall encompass four general land use categories, including General Urban residential, Neighbourhood Centre Area, Dundas Urban Core, High Density Residential and Employment Area. The diversity of land uses provides the opportunity to integrate mixed residential densities in close proximity to neighbourhood and community serving amenities, such as Village Square’s, NHS features, trails and bus transit connections, as well as employment lands.A high quality built form character shall be achieved for all designations, low, medium and high density residential, commercial and employment, delivering architecture that is rich and varied in its form and treatments, creating a distinctive community with visually appealing streetscapes. Each individual residential building massing shall reflect a singular and coherent influence, whether it be Victorian, Georgian, French Chateau, English Manor, Craftsman, Tudor, Gothic Revival, Modern, etc. Other built form types, such as residential high-rise, mixed-use and commercial buildings may adopt more contemporary architectural influences. The design and siting of new built form shall comply with the requirements of the “North Oakville Urban Design and Open Space Design Guidelines”. The following supplementary general built form guidelines and objectives shall be applied.


3.2 BUILT FORM TYPOLOGIESFurther from Section 2.1 Structuring Elements and corresponding built form guidelines, proposed residential built form within Graydon/Martillac shall consist of the following range of residential densities and typologies, consistent with the guidelines outlined in the North Oakville East Secondary Plan (February, 2008): • General Urban Residential - predominantly single-detached dwellings with

potential for semi-detached and townhouse units;

• Neighbourhood Centre Area - predominantly townhou se dwellings with potential for live/work units, retail and/or community facilities/services;

• Dundas Urban Core - medium-density residential, including front and rear loaded townhouses, back-to-back townhouses and low-mid storey apartments and potential for live/work units, retail and/or community facilities/services;

• High Density Residential - medium-high density residential, including front and rear loaded townhouses, back-to-back townhouses and low-mid storey apartments;

• Employment Area - serves as an extension of the Employment lands designated for the North Oakville West Secondary Plan.

3.1 GENERAL BUILT FORM GUIDELINES• Architectural design shall support creative expressions, encouraging variation

within a consistent program of design.

• Both contemporary and tradition based architectural influences may be used to define and distinguish blocks and neighbourhoods.

• Built form located adjacent to or fronting onto public open spaces and exposed to important view termini shall have a particular emphasis with regards to design articulation and visual interest.

• Built form should be designed and oriented to respond appropriately to its context within the community, with respect to priority lot locations and public realm landscape design intentions.

• Height and massing appropriate to the street type and width shall promote a pedestrian-friendly, appropriately scaled street environment.

• The use of high quality, durable, low maintenance building materials should be specified to achieve the desired architectural theme of the home.

• Architectural style, design proposals and location criteria for all built form shall be evaluated through the Town of Oakville’s architectural approval process.


3.2.1 Single-Detached DwellingsSingle detached dwellings, typically in the form of two and three-storey massing, are expected to encompass the majority of residential dwellings within the Graydon/Martillac community. Built form design should address the following guidelines: • Single detached dwellings may have one to three-storey massing. Where a

third storey is proposed, it should be incorporated into the roof massing.

• To ensure appropriate massing relationships and harmonious transitioning, careful consideration shall be given to the siting of dwellings. Significant variation in massing shall be avoided (i.e. bungalow forms beside three-storey dwellings).

• Garages will typically be attached and accessed from the street. The use of alternative garage options (i.e. detached, rear yard or tandem) may be explored where appropriate to the lotting configuration and adjacent garage types. Attached street facing garages shall be integrated into the main massing of the building. Dwelling designs with garages projecting beyond the front facade of the dwelling or porch are discouraged.

• Porches and bay windows should be permitted to encroach into the front flankage and rear yards to provide an interesting facade and animated streetscape. For corner units, the flanking side elevation and rear elevation shall be given a similar level of architectural detailing as the front elevation. Main entries for corner dwellings are encouraged to be oriented to the flanking lot line.

3.2.2 Semi-Detached DwellingsSemi-detached dwellings may add to the diversity of housing choice and streetscape character within Graydon/Martillac, particularly within General Urban Residential areas. Built form design should address the following guidelines: • Elevations may be asymmetrical or symmetrical. Both halves of the building

shall be compatible with respect to design expression and material selection.

• Semi-detached dwellings may be fully or partially attached above grade (i.e. attached at the garage only).

• Semi-detached dwellings should have two to three-storey massing. Bungalow forms are discouraged for this housing type unless wide lot frontages are provided.

• Semi-detached dwellings will have a single car attached garage accessed from the street, accommodating 2 cars per unit (1 in garage and 1 on driveway).

• Porches and bay windows shall be permitted to encroach into the front, flankage and rear yards.

• For corner lot buildings, the main entry of the interior unit shall be oriented to the front lot line, while the main entry of the corner unit should be oriented to the flanking lot line.

3.2.3 TownhousesThe Neighbourhood Centre Area and parts of the General Urban Residential and Dundas Urban Core (Condominium Block) are expected to comprise an assortment of townhouse built form, including street accessed, rear-lane, stacked and back-to-back dwellings. Townhouses make efficient use of land, increase the diversity of built form within a community and achieve higher density populations to support a compact urban village environment. These dwellings are most often clustered to provide strategic density increases as appropriate to the road hierarchy and public transit stops. Built form design should address the following guidelines: • The design of townhomes shall consider the entire building, rather than just

individual units, as well as how individual buildings relate to one another.

• Building composition shall ensure continuity of massing and design, while providing variety along the streetscape.

• Adequate wall articulation is required to avoid large expanses of roof or wall planes: stepping of units and the addition of porches, bays and gables may be considered where necessary.

• To ensure interesting facades, consideration shall be given to the massing, proportions, wall openings and plane variations of building elevations.

• Townhouse units shall feature 2 to 3-storey massing, and bungalow forms should be discouraged.

• For corner dwellings, corner entry units should be oriented to the flankage street, where possible.

• Where consistent with the architectural style, designs with covered front porches or porticos are desirable. To avoid prominence in the streetscape, street facing attached garages shall be integrated into the main building massing.

• Street-accessed townhouses may have single car attached garages from the street. Two car garages may be considered where it can be demonstrated that there are no negative impacts to the front appearance of the dwelling.

• Lane-based townhouses may feature single, one-and-a-half or two car garages with access from a rear lane.

• Rear lane garages may either be attached or detached from the dwelling.

• Where the rear lane garage is detached from the principle dwelling, the design shall be complementary with respect to materials, massing character and quality to provide an attractive built form appearance along the lane.

• Townhouse units with garages backing onto a rear lane shall incorporate upgraded rear architectural treatment.

• The design of garages on corner lots or other areas open to public view shall reflect an enhanced design quality consistent with the principal dwelling.

• To minimize their visibility, consideration shall be given to the location of utility meters, while complying with utility company requirements.

3.2.4 Back-To-Back TownhousesBack-to-back townhouses may be proposed for the Dundas Urban Core (Condominium Block) and High Density Residential areas within GraydonMartillac. This townhouse form is typically a 3-storey freehold structure with front facing garages accessed from a public street or private street. A common demising wall is located along the rear of the units, in addition to the traditional interior side walls. The outdoor amenity space is typically located above the garage or in the form of a balcony. Built form design should address the following guidelines: • Facades shall be designed to incorporate architectural elements found on

lower density residential forms, such as peaked roofs, garages, porches and roof overhangs. Modern architectural styles may be the exception.

• Flat roofs are permitted to allow for rooftop terraces.

• Garages shall not project beyond the front wall or porch face of the main building.

• The treatment of balconies facing the street is critical to the overall design quality of the facade. A well-detailed balcony and railing design shall be consistent with the architectural theme of the building and shall integrate high quality, durable and low maintenance materials.

• Privacy screens, coordinated with the design treatment of the townhouse, shall be provided between the neighbouring units to provide privacy.

• Entrances to each unit should be at-grade and accessed with minimal to no steps, subject to site grading conditions.

Fig. 3.2.5 - Image example of back-to-back townhouse dwellings with both balcony and rooftop terrace amenity areas.


3.2.5 Live-Work TownhousesLive-work units may be proposed within the Dundas Urban Core (Condominium Block) or Neighbourhood Centre Area. Similar in form to townhouses, live-work units are comprised of individual units within a larger building form, with typically commercial (retail, service-related) functions on the ground floor and residential uses above and, in some cases, to the rear. The live-work option provides an opportunity to integrate retail and service functions into a predominantly low to medium density residential neighbourhood, creating a neighbourhood and social focus. Built form design should address the following guidelines: • Building facade design shall establish a positive, cohesive streetscape

appearance that complements neighbouring residential built form. This may be achieved through a variety of elements, including building materials, canopies or awnings, window size and treatment, lighting and signage.

• A coordinated signage strategy shall be implemented for all units within each building, that is appropriate to a given architectural style. Backlit signage is discouraged.

• Overall building massing shall typically be in the range of 3-4 storeys.

• Ground floor retail/service related spaces may allow for a range of sizes and configurations to provide greater flexibility in the type of use. Large ground floor windows shall be used to better distinguish the commercial use from residential functions above.

• Adjacent streetscape treatment shall reflect a more urban approach, with more expansive sidewalks for easier pedestrian access, paved boulevards to accommodate access from on-street parking and the option to integrate street furniture that will complement adjacent retail/service functions.

• Entrances to each unit shall be ground-related and fully accessible.

• Corner units should provide sideyard treatment that is similarly emphasized as the front facade to appropriately address both street frontages. Unit parking is typically accommodated in a garage located to the rear or side of the building, with access from a rear lane. Garage parking may be supplemented by a rear parking pad, if appropriate to the lot size and unit design and does not negatively impact the rear facade treatment.

• In lieu of a garage, additional access to the retail/commercial function may be considered from the back, with parking provided from the rear lane. Outdoor amenity areas for residential units are typically in the form of a balcony, raised terrace or rear courtyard.

Fig. 3.2.6b - Conceptual cross-section and plan siting for typical live-work townhouses.


3.2.6 Mid to High-Rise Apartments (Condominiums)Mid to high-rise apartment buildings will be located within the High Density Residential area and, potentially, the Dundas Urban Core (Condominium Block) and the Neighbourhood Centre block (up to 5 storeys). These buildings will contribute significantly to the character of the Graydon/Martillac community. They will provide strategic higher density population in close, convenient proximity of major transit routing along William Halton Parkway and Dundas St. West. The buildings may integrate, where feasible, ground floor retail/commercial functions to service the immediate dense population and bring these amenities within easy access of the major transit corridors. Retail/commercial functions can bring a sense of animation and vibrancy to the street and serve as a focus for the surrounding North Oakville East development area. As a unit, buildings shall have a strong orientation to the street, framing the corners and establishing a gateway into the community from the east (High Density Residential area) and, potentially, south (Dundas Urban Core). As such, the proposed mid to high-rise condominiums will greatly influence the character, use and identity of the Graydon/Martillac community.

Fig. 3.2.7 - Image example of a mid-rise apartment building (condominium).


3.2.7 Employment Built FormBuilt form design related to the designated Employment Area lands shall reinforce a positive identity and character for Graydon/Martillac and lands to the west. The primary objective for the development is to create a consistently high quality built environment through the combination of site planning, building massing, architectural detail, materials and landscape treatments. It shall promote a pedestrian friendly environment and establish a strong built form street edge. The design of these buildings shall foster a safe, human scale environment and encourage pedestrian activity, while creating attractive and well functioning employment uses. Built form should address the following guidelines: • Buildings shall have a strong relationship to the adjacent streets, with the

primary facade parallel to the roadway.

• Buildings should be accessible from sidewalks along adjacent streets.

• Corner buildings should be sited close to the intersection and address both street frontages.

• Plain, unarticulated, box-like building designs with large blank walls will not be permitted.

• High quality, durable building materials shall be used. This may include, but should not be limited to architectural glass, steel panels, polished stone, brick and textured concrete panels.

• Buildings should be located to ensure good sightlines for all vehicular access points and to create coherent on-site traffic circulation.

• Glazed areas should be maximized along street frontages and main entry areas, with consideration for an appropriate canopy or arcade treatment for weather protection.

• Loading, service and garbage areas should be integrated into the building design or located away from public view and screened to minimize negative impacts, by a combination of fencing and berms.

• Utility meters, transformers, and HVAC equipment should be located away from public views or appropriately screened.


Fig. 3.2.9 - The primary objective for the employment lands is to create a consistently high quality built form environment through the combination of site planning, building massing, architectural detail, materials and landscape treatments.

S E C T I O N 4

The built form component proposed for Graydon/Martillac shall encompass five general land use categories, including General Urban residential, Neighbourhood Centre Area, Dundas Urban Core, High Density Residential and Employment Area. The diversity of land uses provides the opportunity to integrate mixed residential densities in close proximity to neighbourhood and community serving amenities, such as Village Squares, NHS features, trails and bus transit connections, as well as employment lands. A high quality built form character shall be achieved for all designations, low, medium and high density residential, commercial and employment, delivering architecture that is rich and varied in its form and treatments, creating a distinctive community with visually appealing streetscapes. Each individual residential building massing shall reflect a singular and coherent influence, whether it be Victorian, Georgian, French Chateau, English Manor, Craftsman, Tudor, Gothic Revival, Modern, etc. Other built form types, such as residential high-rise, mixed-use and commercial buildings may adopt more contemporary architectural influences. The design and siting of new built form shall comply with the requirements of the “North Oakville Urban Design and Open Space Design Guidelines”. The following supplementary general built form guidelines and objectives shall be applied.

4.1 CHARACTER AND IMAGEThe design of all dwellings within Graydon/Martillac shall offer a harmonious mix of architectural themes derived from either traditional or contemporary styles. The use of distinctive and well-designed architecture employing high-quality materials (brick, siding, stone and stucco, depending on architectural style) will be a consistent characteristic of all proposed development, linking various communities in North Oakville. Stylistic influences may be borrowed from traditional-period Ontario precedents, and may include Victorian, Georgian, French Chateau, English Manor, Craftsman, Tudor, Colonial, Gothic Revival, etc. As well, designs based on a modern, contemporary style may be considered, particularly for the higher density built form. Distinguishing elements from each building design should reflect a single identifiable architectural style. Avoid combining discordant architectural elements in a single building design and ensure that a consistent level of design quality is achieved regardless of the chosen architectural style.

Fig. 4.1 - The character and image of the Graydon/Martillac community will be established through a harmonious mix of built form types and architectural styles.


4.2 ARCHITECTURAL VARIETYHarmoniously designed streetscapes will positively contribute to the character and identity of the Graydon/Martillac community and the broader North Oakville planning area and are key to establishing an attractive, vibrant and livable community. Variety, massing, height and repetition within a group of dwellings will influence the visual appeal of these streetscapes. • Each dwelling form shall be designed with a minimum of two distinct

architectural facade treatment.

• Popular dwelling models for which there is a high demand shall have additional facade treatments to mitigate streetscape repetitiveness.

• Building forms located adjacent or opposite one another shall be compatible with respect to height and massing. Extreme variations shall be avoided. However, exceptions may be considered where mid-high storey buildings are integrated.

• Identical elevations should be used a maximum of three times per row of ten single detached dwellings and and shall not be repeated in dwellings opposite one another. A minimum of two different units should be designed between identical elevations.

• Distinct single detached dwelling forms with the same colour package may be repeated a minimum of every three dwellings.

• Dwellings located opposite from one another shall not have the same colour package.

4.3 MASSING WITHIN THE STREETSCAPEAn attractive streetscape is largely achieved by the arrangement of buildings within the street block. Visually, the grouping and massing of dwellings within a block has greater impact than a dwelling units individual detailing. Height and massing that is appropriate to the context of the street is key to achieving a pedestrian-friendly, comfortable scale environment. Consideration for the following design criteria will encourage harmonious massing within the streetscape: • Building forms located adjacent or opposite one another shall be compatible

with respect to height and massing. Extreme variations shall be avoided. However, exceptions may be considered where mid-high storey buildings are integrated in close proximity to low density dwellings.

• Massing should transition from higher density areas to lower density areas through building designs that achieve harmony along the streetscape.

• Avoid siting 3-storey dwellings adjacent to bungalows, raised bungalows or 1-1/2 storey dwellings.

• 2-storey dwellings sited adjacent to bungalows or 3-storey dwellings shall comprise a minimum grouping of 2 units. Likewise, 3-storey dwellings sited adjacent to 2-storey dwellings shall comprise a minimum grouping of 2 units.

Fig. 4.3 - Building forms located adjacent or opposite one another shall be compatible with respect to height and massing.Fig. 4.2 - Architectural variety shall positively contribute to the character and identity of

the community, while collectively achieving a harmonious streetscape.


4.4 ARCHITECTURAL ELEMENTS

4.4.1 Architectural Detailing• The use of trim elements including frieze board, gable posts, finials, brackets,

arch windows, shutters and shingle effects, as well as masonry detailing such as dichromatic brick, quoining, lintels/headers, pilasters, etc., is encouraged to provide design interest for each dwelling type.

• Trim elements and detailing shall be an authentic expression of a single architectural style. They shall be appropriate to the dwelling scale and massing and shall only include high quality materials and proper installation practices.

4.4.2 Exterior Materials and Colours• The use of high quality materials and detailing that are appropriate to the

architectural style of the dwelling is essential in establishing an authentic representation.

• Dwellings will be predominantly constructed of brick, stone, stucco, cement board and siding, as appropriate to the architectural style.

• The selection of accents and decorative detailing shall be consistent with the architectural style.

• Authentic colour arrangements are a key element in effectively communicating a particular architectural style.

Fig. 4.4.2a - Examples of exterior main facade cladding materials. The selection of materials and colours shall be consistent with the architectural style.

BRICK AND STUCCO STONE AND STUCCO SIDINGBRICK

Fig. 4.4.2b - Authentic colour arrangements are a key element in effectively communicating a particular architectural style.


4.4.3 FenestrationProminent fenestration, consistent with the dwelling’s architectural style, is required for all elevations facing public areas. The intent is to enhance the front facade appearance of each building or unit and provide a close relationship between building and street. • Windows should be proportioned and include design elements consistent

with the architectural style of the built form, including integrated muntin bars where appropriate.

• Consideration shall be given to low maintenance, durable window cladding, such as vinyl or fibreglass.

• Vertical, rectangular window configurations are encouraged to better fit with most traditional architectural styles. Other window formations may be considered where consistency with the architectural style is maintained.

• All window related elements (sills, lintels) shall be consistent with the given architectural style.

• Window types, such as bay windows, should be used as appropriate to the location and siting of the dwelling, consistent with the given architectural style.

• Window placement in combination with other architectural elements is an effective method to animate rear or side elevations exposed to public view.

4.4.4 Porches• Some of the dwelling designs offered should feature front porches or porticoes

to encourage social interaction and provide ‘eyes on the street’.

• To mitigate the visual impact of garages and foster an attractive, comfortable pedestrian streetscape environment, porches shall be located closer to the street edge than garages.

• For corner units, wraparound porches are encouraged, where appropriate to the architectural style, to address both street frontages.

• Main dwelling entrances shall be visible from the street and appropriately lit.

• Porches, where applicable, should be sized to comfortably accommodate seating and encourage use.

Fig. 4.4.3 - Window placement in combination with other architectural elements is an effective method to animate rear or side elevations exposed to public view.

Fig. 4.4.4 - Porches shall be located closer to the street than garages and sized to comfortably accomodate seating and encourage use.


4.4.5 Roof FormThe design of the roof form will significantly impact the overall appearance of the dwelling. Variation in roof types and forms are encouraged to emphasize interesting roof lines for street facing or flanking dwellings. Depending on the architectural style, roof forms may include gables, dormers, hips, ridges, mansards, etc. that will establish an effective roof line. • Roofing materials, whether asphalt, metal, wood or composite materials,

shall be consistent with the architectural style.

• The use of upgraded or alternative materials may be considered to distinguish neighbourhood areas or priority lots.

• Roof forms and materials shall appropriately fit with neighbouring dwellings to help establish a harmonious appearance. Stark changes in form or material is discouraged amongst adjacent dwellings.

• Main roof slopes shall comply with accepted standards for a given architectural style and dwelling type.

• Roof overhangs shall follow acceptable standards as per a given architectural style.

• Where possible, roof plumbing stacks, gas flutes and vents should be located away from street view along the rear roof slope.

• Skylights should have a flat profile and preferably located away from street view at the rear roof slope.

Other proposed built form, including mid-rise condos, mixed-use buildings, commercial buildings and live-work units may integrate flat roofs, as appropriate to the architectural style, particularly in more contemporary or modern design influences.

4.4.6 GaragesGarages in Graydon/Martillac will include predominantly street-accessed, with rear accessed garages associated with the Neighbourhood Centre Area and, potentially the High Density Residential block and Dundas Urban Core.

4.4.6.1 Street-Accessed Garages• Where garages are attached, they should be integrated into the main massing

of the dwelling with limitations to their projection into the front yard.

• Attached garages located within the front or flankage yards and accessed from the street shall be of a similar architectural style and proportional scale to the adjoining dwelling.

• Street facing garages should be minimized in scale in compliance with the vision for North Oakville. The following are acceptable placement options for attached street facing garages:

• Site the garage to the side of the dwelling, set back from the main front wall;

• Integrate the garage into the main massing of the dwelling, in line with the main front wall;

• Integrate the garage into the main massing of the dwelling, in line with the porch projection (not including the front steps).

• Where a double car garage is proposed, it should be divided into two individual garage doors/bays separated by a dividing column. The dividing column or pier should be comprised of a material consistent with the dwelling facade (brick, stone, siding, stucco) that will allow it to blend in with the overall appearance.

• Only sectional, roll-up type garage doors shall be proposed.

• A variety of garage door header treatments may be considered, consistent with the architectural style of the dwelling.

• Light fixtures mounted to the side of above the garage door is encouraged and shall be consistent with the architectural style of the dwelling.

• Where dropped garage conditions occur on rear-to-front sloping lots, alternative architectural techniques shall be used to minimize the extent of wall space between the top of the garage door and the underside of the roof soffit. The following techniques may be considered:

• Increase the garage door height as appropriate to the scale of the dwelling;

• Lower the garage door and/or increase the roof pitch;

• Add a decorative gable louvre or feature;

• Integrate architectural features, such as a decorative brick pattern, to break up the wall massing.

Fig. 4.4.5 - Roof forms and materials shall appropriately fit with neighbouring dwellings to help establish a harmonious appearance.


4.4.6.2 Rear-Accessed GaragesRear-accessed garages typically refer to lane-based townhouses found within the Neighbourhood Centre Area and, potentially, within the Dundas Urban Core and High Density Residential block. • Lane accessed garages for townhouses and single detached dwellings may

be attached or detached from the dwelling. Both single and double car garages may be permitted.

• The design of garages shall be consistent with the architectural style of the dwelling with respect to materials, massing, character and quality.

• The garages shall be designed with articulated rooflines and can integrate gables, dormers or other architectural features that will enhance the appearance from the public lane.

• Corner lot garages shall be designed with upgraded features in consideration of its prominence along the street.

• Parking pads may be permitted beside the rear yard garage where space permits. For corner lots, parking pads should not be sited between the garage and the street line, but, rather, between the garage and the interior lot line.

• Habitable and/or amenity space above a rear garage may be permitted to add variety to the lanescape and enhance the character of the neighbourhood.

• Pairing of garages within the lane may occur where advantageous to lot layout and vehicular accessibility.

• Only sectional, roll-up type garage doors shall be proposed.

• Garages shall be sited to provide for access and drainage from the rear yard of the unit to the laneway.

• A municipal address plaque or sign shall be provided on the garage wall facing the lane and it shall be well lit along with the garage entry.

Fig. 4.4.6.1 - Example of how garages integrated into the main massing of the dwelling, set-back from the main front wall/porch.


4.4.7 Utility and Service Elements• Public views towards utility meters and utility service connections (hydro,

water, natural gas, telephone, etc.) should be minimized by siting the utility on side walls (perpendicular to the street) and facing an interior side yard.

• Where there are no interior side yards, utility and service connections should be screened from view through recession into the wall where possible, subject to standard access requirements for a given utility. For townhouses, utility meters should be located in the rear lane, where applicable, or screened/recessed into the wall where possible, subject to standard access requirements for a given utility.

Fig. 4.4.6.3 - Example of where public view towards utility meters and utility service connections are minimized by siting and consolidating the utilities on side walls (perpendicular to the street).


4.5 PRIORITY LOTTINGPriority lots are located within areas of the community that have a greater degree of visibility from the public realm (refer to Fig. 4.5 - Priority Lot Plan). Their visual prominence from adjacent streets and open spaces requires that the siting, architectural design and landscape treatment for each of these dwellings represent an upgraded quality in recognition of the landmark location within the community. Built form on priority lots shall be designed to ensure an attractive architectural appearance is achieved, with massing appropriate to the lot designation. Priority Lots include:• Corner lot dwellings

• View terminus dwellings

• Upgraded rear and side architecture dwellings

• Village Square facing dwellings

• Gateway location

Fig. 3.2.9 - The primary objective for the employment lands is to create a consistently high quality built form environment through the combination of site planning, building massing, architectural detail, materials and landscape treatments.

4.5.1 Corner Lot DwellingsDwellings on corner lots typically have the highest degree of public visibility within the streetscape and are important in portraying the image, character, and quality of the community. • Dwelling designs must be appropriate for corner locations, with elevations

that address both street frontages. Dwelling designs intended for internal lots will not be permitted unless the flankage elevation is upgraded to address the street.

• Both street frontages for corner lot dwellings shall reflect similar levels of architectural design and detail with respect to massing, roofline character, fenestration, materials, details, etc.

• Distinctive architectural elements, such as wraparound porches, porticos, bay windows, ample fenestration, window treatment, wall articulation, brick arrangement and colour, etc. appropriate to the architectural style of the dwelling, are encourage on the flankage side to create an interesting streetscape and emphasize the corner dwelling’s landmark function.

• The main entry of the corner dwelling is preferred on the long elevation facing the flanking street. Alternatively, the shorter (front facing) side of the lot may still integrate the main entry for the dwelling.

• A privacy fence shall enclose the rear yard portion of the corner lot dwelling. In order to minimize the length of the fence facing the flanking street, it shall begin as close as possible to the rear corner of the dwelling.

• Rear lane garages on corner lots shall have upgraded side elevations facing the street.

• At corner gateway locations, porches and main entries shall be oriented away from the corner and associated gateway location to ensure appropriate accessibility.

Fig. 4.5.1a - Conceptual plan view of a corner lot dwelling.

Fig. 4.5.1b - Example of a corner lot dwelling with well-articulated architectural treatment and street orientation on both sides.


4.5.2 View Terminus DwellingsView terminus dwellings are situated at the top of T-intersections or street elbows, where one road terminates at a right angle to the other. These dwellings play an important role in defining a terminating long view corridor. • A prominent architectural element, massing or material arrangement should

be provided to terminate the view.

• Driveways should be located to the outside of the lot, rather than in-line with the view corridor, to reduce the impact of the garage on the terminus view and allow for front yard landscaping to become the focus, along with the architectural treatment.

4.5.3 Upgraded Rear and Side Architecture DwellingsWhere a dwelling’s rear or side elevation is prominently exposed to the public realm, both the front and side/rear elevations shall be designed with similar architectural emphasis with respect to details, materials, roofline character, fenestration, wall articulation, etc. • The design of the applicable rear and/or side facade shall, therefore,

acknowledge the prominent exposure to the public realm.

• Potential upgrades to the applicable elevation includes bay windows or other additional fenestration, window treatments, frieze boards, brick detailing (quoining, dichromatic), gables and dormers, wall articulations, etc.

4.5.5 Gateway LocationSimilar to corner lot dwellings, gateway dwellings are characterized by a very high profile location within the community that results in a significant impact on the perception of the image, character and quality of the community from the outside. • Built form massing, orientation and detailing shall be the principal component

for defining the gateway. This can be achieved in residential, commercial or employment land uses situated at gateway locations within the Graydon-Banning/Martillac community.

• Associated landscape features, both hardscape and softscape, may be integrated with built form massing to emphasize the gateway function.

• Although designed as a corner lot with facade treatment addressing both street frontages, the main entry, garage and porch should primarily address the short (front facing) street frontage, particularly where the flankage faces an arterial road.

• Refer to 4.5.1 Corner Lot Dwellings for additional guidelines.

4.5.4 Village Square Facing DwellingsGiven the prominence of the Village Square’s and it’s role as the focus and gathering space for the community, dwellings that front onto the parks shall be designed in a manner that considers and complements the exposure from this public open space. • Given that these dwellings are very visible from the main gathering space

within the community, an enhanced architectural treatment consistent with the architectural style shall be implemented, such as substantial front porches, prominent, well proportioned windows, a projecting bay, articulated wall treatment and other design elements that enhances the front elevation.

• The use of upgraded materials and detailing, such as stone or precast elements, dichromatic brick, quoining, etc. shall be integrated into the elevation design.

• Dwellings are encouraged to have wider and deeper porches that effectively allow for multiple seating and will promote ‘eyes on the street’, which results in an informal monitoring of the park and its activities.

• Park facing dwellings shall have available a variety of model types, elevation types and colour packages. However, a cohesive, harmonious relationship shall be achieved for all lots.

Sustainable development practices balance the health and well-being of the environment and related resources with the pressure of urbanization, bringing forward strategies to better manage increased population densities, resource and energy consumption, and vehicular traffic volumes. Graydon/Martillac shall be designed with a strong emphasis on the integration of sustainable practices and techniques that will result in a transit-oriented community which is highly walkable and cyclist friendly, with a potential mix of uses (residential, employment, commercial) and a diversity of housing types and densities. The principles and objectives of sustainability have applications in all areas of the development. The community’s context and the prominent Natural Heritage System that surrounds it and is woven into its fabric makes sustainable development and low-impact design a key priority. The following sustainable development practices shall be implemented.

5.1 SUSTAINABLE DEVELOPMENT PRACTICES

5.1.1 HardscapingObjectives for hardscaping should balance functional requirements of vehicular and pedestrian circulation with sustainability, accessibility, maintenance and aesthetic considerations. Where feasible and appropriate to the location, select paving materials that allow for increased permeability and infiltration, while accommodating circulation and maintenance requirements. • Preference shall be given to the selection of permeable or porous paving

materials, such as open joint pavers, porous concrete or asphalt and/or precast turf-grid products.

• Paved areas used for snow storage are encouraged to integrate permeable paving to absorb snow melt on site.

• Where possible, utilize surface materials that contain recycled or sustainable materials.

• The use of light coloured surface materials, such as concrete, white asphalt or light-coloured unit pavers is encouraged to decrease heat absorption and ambient surface temperatures (urban heat island effect).

• All paving materials and installation to be selected and designed to withstand traffic impacts and maintenance requirements.

Fig. 5.1.1 - Examples of light coloured unit paving which reflects light and serves to reduce the urban heat island effect, as well as allow for permeability and infiltration.


5.1.2 Softscaping• Naturalized, low maintenance planting shall be specified where appropriate.

• A priority shall be placed on utilizing xeriscape planting techniques, selecting drought-tolerant species to conserve water.

• Landscape features, such as berms, tree and shrub groupings, and ‘green’ walls shall be utilized to screen undesirable views to adjacent or nearby uses (traffic, railway tracks, buildings) and on-site servicing areas (loading docks);

• Provide landscaping that increases the urban canopy, creates comfortable micro-climate conditions, mitigates negative seasonal effects (wind breaks or shade canopy) and contributes to overall biodiversity. Strategically place dense deciduous canopy trees to let sunlight and warmth into buildings and public open spaces and sidewalks during winter, while in summer creating a canopy that shields people and buildings from sun, glare and heat, and allows breezes to flow through;

• ‘Green’ screens and other landscape wall features may be situated on or near building façades to reduce ambient heat and minimize air conditioning requirements;

• To mitigate the impact of wind on a site, evergreens should be used as a windscreen for undesirable wind exposures;

• Use only organic or biological fertilizers and weed and pest controls, without potentially toxic contaminants;

5.1.3 Water Conservation and Management• Utilize xeriscape planting techniques, selecting drought-tolerant plant species

to conserve water and avoid the need for irrigation systems;

• If irrigation is required (e.g. sports fields), water should be provided by non potable sources (roof, parking lot, grey water) where feasible;

• Utilize rainwater harvesting techniques to use stormwater resources for irrigation;

• Utilize techniques and measures to divert rainwater away from a previously connected sewer line. These techniques allow the water to be used for planting and groundwater recharge and reduce outflow to overburdened sewage and storm systems;

• Implement roof downspout disconnection to prevent water from reaching the sewer system and allow it to be managed on site, whether through a storage device, permeable surfaces or an infiltration system;

• Where feasible, consideration should be given to the use of soakaway pits, whereby a roof downspout is connected to an underground pit lined with gravel or coarse aggregate, temporarily storing the water until it is absorbed into the ground;

• Similar to soakaway pits, infiltration trenches direct water to an at-grade trench filled with aggregate material, where it is held until it infiltrates into the ground;

• Depending on the type of built form, rain barrels or similar container system may also be considered to manage roof runoff;

• Where feasible, integrate bio-retention swales as an effective technique for managing stormwater within expansive areas of runoff. These may include swales, vegetated islands, rain gardens, etc.;

• Bio-retention swales typically include planting (groundcover, shrubs and potentially trees), curb inlets for stormwater flow and a water infiltration/storage area that supports vegetative growth. Depending on site characteristics, perforated sub-drains and overflow catchbasins may be required to manage excess water;

• Composition of swale components shall be designed to ensure surface water is fully drained within 48 hours of the end of any rainfall event;

• Undertake soil amendments to increase topsoil depths and restructure compacted soils for improved infiltration;

• The degradation of slopes leading to erosion and sedimentation control problems results from the effects of rain and wind on unprotected slopes, with potential negative impacts for water quality and stormwater management infrastructure. As such, developers and contractors shall be diligent in preventing erosion on site, both, during the construction phase and following construction completion.

5.1.5 Lighting• Achieve a balance between safety and security and a reduction in energy

consumption;

• Utilize energy efficient luminaires and bulbs to satisfy lighting requirements; Select lighting poles, luminaires and light levels that are appropriate to the site and function to avoid excessive illumination and light pollution.

5.1.6 Materials• Green roof technologies or reflective, light-coloured roofs should be

encouraged for employment, office and institutional buildings, as well as higher storey residential buildings, in order to reduce solar heat absorption and building energy demand;

• Encourage the use of local materials to avoid unnecessary long distance transport of building materials;

• Encourage the use of materials that have been sustainably harvested. 5.1.4 Walkability/Transportation AlternativesWalkability is one of the primary tenets of the Graydon/Martillac neighbourhood, as an extension of the greater North Oakville sustainability strategy.• Open spaces and amenities within the development shall be located within

comfortable walking distance of the majority of residents.

• Proposed trails associated with natural features in surrounding neighbourhoods have been linked with the sidewalk network, offering convenient and enjoyable pedestrian connections.

• To encourage a reduction in automobile usage, ensure bicycle parking and public transit connections are integrated into the design of major community facilities or gathering areas.

• Where applicable, particularly for employment lands, the sizing of parking facilities shall be minimized to meet, but not exceed, zoning requirements.

• As an alternative to automobile use, encourage cycling through an emphasis on safe, efficient cycling connections and the integration of appropriate bicycle storage and locking facilities with options for weather protected storage.

• Similar to cycling, encourage public transit use through incentive programs that allow for a decrease in car usage and enables a reduction in parking facility capacity.

The design guidelines, principles, standards and recommendations contained in the Graydon/Martillac Urban Design Brief (UDB) sets out to achieve a coordinated approach to urban design and govern the preparation of detailed open space, landscape and built form design at the Draft Plan approval stage. It also provides design direction for the development of future site plans within the community’s character areas (Dundas Urban Core, High Density Residential block) and employment lands. The UDB has addressed pertinent urban design issues as applied to the community goals and objectives, land uses, structuring elements, streetscapes, open spaces, built form, sustainability and low-impact development strategies. The intended result is the development of a community that is reflective of the fundamental key design tenets of broader North Oakville planning area.
