1. Purpose

Walker, Nott, Dragicevic Associates Limited was retained by Tamarack (Queen Street) Corporation to prepare a Planning Rationale in support of a Draft Plan of Subdivision and Zoning By-law Amendment applications for Cardinal Creek Village.

The Planning Rationale Report is required support applications for draft approval of subdivision and re-zoning, and in this regard this report will provide background information that the applications are consistent with the Provincial Policy Statement (‘PPS’); conform with the City of Ottawa Official Plan; and are consistent with the Cardinal Creek Village Concept Plan.

2. Site Description and Location

The lands subject to the development applications (i.e. the subject site) are located within the Cardinal Creek Village community and area are generally defined by and the Ottawa River to the north; Cardinal Creek to the west; Frank Kenny Road/Ted Kelly Lane to the east; and, Old to the south. The subject site consists of approximately 121 hectares. A block located on the south side of Old Montreal Road is also included in the applications to allow for the continued operation of the existing commercial nursery garden.

The larger Cardinal Creek Village community consists of approximately 208 hectares and is located in the east end of the City of Ottawa, east of the Orléans urban community. The boundaries of the area are generally defined by Ottawa Road 174 and the Ottawa River to the north; Cardinal Creek to the west; Frank Kenny Road/Ted Kelly Lane to the east; and, Urban area limits to the south.

Current uses of the lands north of Old Montreal Road are diverse and include large lot rural residential, institutional, and nursery and landscape supply uses.

The property consists of a series of four plateaus rising north to south beginning near the Ottawa River in the north at an elevation of approximately 50m ASL and stepping up towards the highest elevation at 94m along the southern boundary.

The topographic character of the area has also significant influence on the physical character of the area with respect to the effect of grades on the location of roads, servicing infrastructure and lands uses requiring level site areas (e.g. parks). However, this topographic character also provides opportunities for views and vistas from within the community toward the Ottawa River and Gatineau Hills and can add character to the overall community.

3. Proposed Plan of Subdivision

The proposed plan of subdivision for the subject site comprises approximately 121 hectares and, as previously noted, is located between Ottawa Road 174 and Old Montreal Road; east of the Cardinal Creek 1.

Generally described, the plan of subdivision includes the following structural component: • A major collector (north-south) road between Ottawa Road 174 and Old Montreal Road; • A minor collector road running internal to the subject site and connecting to Old Montreal Road in two locations; • Natural heritage areas identified for preservation including areas along the Cardinal Creek Valley and the escarpment ridge; • Two elementary school sites (acquisition to be determined by the relevant School Boards); • A Community Park to be located on the east side of the major collector road; and, • Two Neighbourhood Parks to be located so as to serve the residential areas situated to the west and east of the major collector road.

The proposed subdivision layout is consistent with the framework established by the Cardinal Creek Concept Plan (June 2013) with minor variations.

Those minor variations have arisen out of the desire for the existing commercial nursery garden operation to remain functional during the initial stages of development. Accordingly, the minor collector road located north of Old Montreal Road has been adjusted to create an interim parcel around the existing operation. This road adjustment has resulted in concomitant effects on the park, school and residential blocks/lots. In addition, a block of land situated south of Old Montreal Road has been included in the draft plan in order to allow for the re-location of the commercial nursery garden operation as phased development proceeds to the north of Old Montreal Road.

4. Planning Framework

The following provides a brief summary of the City planning policy framework that underpins the Cardinal Creek Village Concept Plan.

CITY OF OTTAWA OFFICIAL PLAN

The City of Ottawa most recent comprehensive five year Official Plan Review (Official Plan Amendment (‘OPA’) No. 76) was adopted by the Council of Ottawa on June 24, 2009 and was approved with the modifications by the Minister of Municipal Affairs and Housing on December 24, 2009 and appeals were finally resolved by the Municipal Board in June 2012. OPA 76 established a number of expansions to the Urban Area including the Cardinal Creek Village lands.

Accordingly, the Cardinal Creek Village lands were designated by OPA 76 as ‘Urban Expansion Study Area’ and are subject to a policy framework (Section 3.11) that requires a number of comprehensive studies to evaluate the area’s land use potential (including, among other matters, natural heritage, servicing and transportation) and determine a detailed land use concept for the lands.

A Concept Plan for the Cardinal Creek Village lands was approved and the implementing Official Plan Amendment (No.123) adopted by Ottawa Council on July 17, 2013 (and came into force and effect on August 16, 2013)

CITY OF OTTAWA ZONING BY-LAW

The lands subject to this application are currently zoned ‘RU – Rural” and a concurrent application to amend the Zoning By-law is being submitted.

The proposed zoning is as follows: • For the residential lots – R3; Residential Third Density Zone • For the neighbourhood and community park blocks – OS1: Parks and Open Space Zone • For the elementary school blocks – I1: Minor Institutional Zone and R3; Residential Third Density Zone (to allow residential development should no school board acquire the school blocks) • For the natural heritage blocks – EP: Environmental Protection Zone • For the mixed use block at the northwest corner of Old Montreal Road/Major Collector Road – R4: Fourth Residential Density Zone • For the mixed use block on either side of the Major Collector Road (at the base of the escarpment) – R4: Fourth Residential Density Zone • For the mixed use blocks abutting Ottawa Road 174 – retain their existing zoning until such time as the detailed design concept/guidelines required by Council resolution is completed. • Other open space blocks - OS1: Parks and Open Space Zone

6. Supporting Studies

The following provides a brief summary (extracted from each report) of the supporting studies being submitted with this application.

FUNCTIONAL SERVICING REPORT The lands subject to the Plan of Subdivision and Zoning By-Law Amendment applications fall within the study area of the Cardinal Creek Village Master Servicing Study (DSEL, July 2013), which identifies the preferred water, wastewater and stormwater management systems to support the proposed development. The Master Servicing Study (MSS) was prepared in accordance with the integration provisions of the Municipal Engineers Association’s Municipal Class Environmental Assessment (June 2000, as amended in 2007 & 2011), which combines the requirements of the Planning Act and the Environmental Assessment Act. The Cardinal Creek Village Master Servicing Study (DSEL, July 2013) Class Environmental Assessment was approved on August 21, 2013, clearing the servicing infrastructure projects identified in the report for future design exercises and construction.

As a next step in the development planning process, a Functional Servicing and Stormwater Management Report (FSR) has been prepared under separate cover to further detail the servicing plan for the subject lands. The FSR links the requirements outlined in the MSS with the current Plan of Subdivision and Zoning By-law Amendment applications and defines the course of subsequent detailed design, review, and acceptance of the development services. The key findings of the FSR are:

• Water supply will be provided through extensions of the City’s existing 1E and 2E Pressure Zone infrastructure and an on-site watermain network designed in accordance with City Guidelines. Water supply to the subject lands was previously contemplated in the approved MSS, confirming capacity is available to support the development. • Wastewater services will be provided through a network of gravity sewers that outlet to the Collector Sewer. The off-site connection between the subject lands and the Collector Sewer was contemplated in the approved MSS, confirming capacity is available to support the development. • Stormwater service will be provided through gravity sewers and open ditches that outlet to a new stormwater management pond near OR 174. The pond will outlet to the Ottawa River via an existing culvert and a new outlet pipe proposed under OR 174. • An oil and grit separator unit will also be provided, to treat weeping tile drainage and select stormwater flows from a portion of the development. These flows will be directed to the downstream portion of the North Tributary, as part of a mitigation program to compensate for the proposed closure of the upstream portion of the North Tributary. • Fish habitat creation is proposed within the North Tributary and Cardinal Creek, to mitigate the loss of the upstream portion of the North Tributary, and the impacts associated with realignment of the North Tributary in the vicinity of the Hydro One corridor and a culvert crossing of the North Tributary. • The stormwater management system is designed to meet MOE Enhanced level of suspended solid removal before stormwater is discharged to the North Tributary and Ottawa River. The stormwater management system has been designed to control stormwater flows destined to Cardinal Creek, in order to maintain a level of stream erosion such that Cardinal Creek can continue to fulfill normal functions.

Walker, Nott, Dragicevic Associates Limited 12

PLANNING RATIONALE October 2013 Cardinal Creek Village | Subdivision Application

• The above-mentioned stormwater management design is consistent with the design concept and design criteria presented in the approved MSS.

The FSR will require approval under the Planning Act as supporting information for the Draft Plan of Subdivision application. Project-specific approvals are also expected to be required from the City of Ottawa, Rideau Valley Conservation Authority, Ontario Ministry of the Environment, and Hydro One.

Water Supply The municipal water servicing approach for the subject lands is for the northern and western portions of the lands to be connected to existing infrastructure in the City of Ottawa’s 1E Pressure Zone. The remainder of the site is to be fed from existing infrastructure in the 2E Pressure Zone. The proposed on-site local watermain network consists of 150mm and 200mm diameter local watermains that are connected to a trunk watermain system. The trunk system consists of:

• A 1E feedermain extending from an existing feedermain west of the site, running through City and Hydro One property, and crossing over Cardinal Creek via the existing Hydro One corridor culvert. • A 2E feedermain extending north on Trim Road from the intersection at Old Montreal Road, then extending east along Dairy Drive, north within City-owned lands (west of 1001 Dairy Drive), and east within City-owned lands (north of 1001 Dairy Drive) before crossing under Cardinal Creek via trenchless watermain construction. The feedermain is to be extended and capped north of 1001 Dairy Drive as part of a concurrent City contract. • 1E and 2E feedermains crossing Cardinal Creek at Old Montreal Road, within the road right- of-way. The feedermains are to be extended to the study area in a concurrent City contract.

The watermain network follows the proposed road network, with the exception of servicing easements across the northernmost ridge, across the North Tributary, alongside and within the Hydro One corridor, and through a residential block in the southwestern portion of the Draft Plan of Subdivision.

The proposed watermain network is consistent with the recommendations and analysis contained in the MSS, except for minor alignment changes due to the refined road network presented in the Draft Plan of Subdivision. The proposed watermain network meets the City of Ottawa design guidelines for development: specifically, the hydraulic analysis completed for the subject lands confirms that there is adequate supply and pressure in the City’s 1E and 2E Pressure Zone water networks to support the proposed development, and confirms adequate fire flows are available.

Wastewater Collection The Trim Road Collector sanitary sewer is the proposed municipal wastewater outlet for the site. A network of local gravity sewers ranging from 200 mm to 375 mm in diameter is proposed within the subject lands, connecting to a proposed trunk gravity sanitary sewer network. The proposed sewers follow the proposed road network, with the exception of servicing easements across the northernmost ridge, across the North Tributary, adjacent to and within the Hydro One corridor, and within adjacent City property.

Walker, Nott, Dragicevic Associates Limited 13

PLANNING RATIONALE October 2013 Cardinal Creek Village | Subdivision Application

The proposed sanitary sewer network meets the City of Ottawa design guidelines for development.

The proposed network is consistent with the recommendations and analysis presented in the MSS, except for minor alignment changes due to the refined road network. The MSS confirmed available downstream capacity, using an allowance to account for the future development of the subject lands. The proposed sanitary discharge from the subject lands is within the allowance given in the MSS, confirming that the downstream sanitary sewers can support the proposed development presented in the Plan of Subdivision.

Stormwater Management In terms of stormwater management, a treatment train approach is identified, using best management practices for site controls, a dual drainage system consisting of underground storm sewers and overland flow routes, and end-of-pipe stormwater management facilities. Two stormwater management facilities are proposed within the subject lands: one stormwater management pond discharging to the Ottawa River (to provide quality control) and one oil and grit separator unit discharging to the North Tributary (to provide quality control). The servicing plan also incorporates conveyance channels to direct flows to the stormwater management facilities and a cut- off swale along the eastern edge of the Draft Plan of Subdivision, in order to accommodate existing drainage from residential areas east of Ted Kelly Lane.

The design of the storm sewer network is in accordance with City of Ottawa design guidelines and the sewer network follows the road network, with the exception of servicing easements within the Hydro One corridor, across the northernmost ridge, and across the North Tributary. The outlet for the proposed stormwater management pond consists of an existing 1.5 m wide x 1.15 m high concrete box culvert and a new 2100 mm diameter outlet pipe that will convey the pond outflows and outflows from the proposed cut-off swale underneath OR 174 to the Ottawa River.

A site grading scheme has been developed to minimize earthworks and provide major system conveyance to the receiving watercourses (Cardinal Creek, the North Tributary and the Ottawa River). The Ottawa River, Cardinal Creek, and the North Tributary support fish communities, and the stormwater management plan has been designed accordingly, to ensure enhanced quality control of stormwater runoff (long-term average removal of 80% Total Suspended Solids) and to manage erosion impacts within Cardinal Creek.

The Draft Plan of Subdivision and associated servicing plan propose the closure of the upstream portion of the North Tributary, a realignment of the North Tributary in the vicinity of the Hydro One corridor, and a culvert crossing of the North Tributary. The oil and grit separator unit has been identified to divert treated weeping tile flows and storm flows up to the 2-year storm design flow rate from a portion of the proposed development lands to the North Tributary. This is to compensate for reductions in stream flow due to the closing of the upstream portion of the North Tributary and due to drainage catchment diversion and urbanization. As recommended in the MSS, the loss of the North Tributary (loss of approximately 2,000 sq.m.) is also to be mitigated by providing fish habitat compensation at a 1:1 ratio. The proposed works include habitat creation in the North Tributary and Cardinal Creek. The proposed filling, crossing, and re-alignment of the North Tributary will require RVCA review and approval as part of detailed design, and may require design changes to address environmental impacts.

Walker, Nott, Dragicevic Associates Limited 14

A slope reinstatement program is recommended at one location in the Cardinal Creek ravine, south of the Hydro One corridor, where an existing slope failure has occurred. The proposed works will require RVCA review and approval as part of detailed design, and may require design changes to address environmental impacts.

The above-mentioned stormwater management design is consistent with the design concept and design criteria presented in the approved MSS.

TRAFFIC IMPACT STUDY The TIS report presents details of the proposed land uses, development phasing, road network and pedestrian and cycling facilities within the Draft Plan area. An assessment of existing and future traffic demand and roadway capacity has been carried out and recommendations for the implementation of required infrastructure have been provided. The study has followed the City of Ottawa Transportation Impact Assessment Guidelines (October 2006). Future background traffic projections in the study have been based on information provided in the Cardinal Creek Village TMP and CTS reports 2.

Based on the traffic analyses undertaken in the Transportation Impact Study, the main findings, conclusions and recommendations are as follows:

• Transit service will be provided to the development through the modification of existing routes initially, and by the introduction of new routes as the construction of the internal collector road system is progressed. Further consultation and coordination with OC Transpo will be required during the detailed design of each phase to finalize the details of transit routing and bus stop locations. • The pedestrian facilities in the development will be provided in accordance with the principles identified in the Cardinal Creek Village Concept Plan. Sidewalks are proposed along both sides of the major and minor collectors roads and along at least one side of the other streets in the community. The location of pathway connections to the future multi-use pathway proposed along Cardinal Creek is indicated on the Draft Plan of Subdivision. • At full-build out of the proposed Draft Plan, it is estimated that the development will generate 793 new vehicular trips during the weekday morning peak hour and 1,555 new trips during the afternoon peak hour. This estimate has assumed that 54% of all vehicular trips generated by the residential component of the development will be regional (or commuter) trips. The other 46% will be local trips within Orléans. It has also been assumed that the transit modal split (TMS) in the development will be 41% for regional/commuter trips and 7% for local trips at the horizon years in the study.

2 The City of Ottawa and the United Counties of Prescott and Russell are currently undertaking a Class Environmental Assessment (EA) for improvements to Ottawa Road 174/ County Road 17 from the Highway 417 interchange to the Town of Rockland. The traffic analysis in this TIS report has utilized future background traffic projections that have been based on information provided by the City of Ottawa from the City traffic model. Updated traffic projections and an assessment of future requirements along the Ottawa Road 174/ County Road 17 corridor will be determined by the ongoing EA study.

• The intersection of Ottawa Road 174 and Trim Road is presently operating at close to its theoretical capacity during both the weekday morning and afternoon peak hours. By 2021 it is projected that the peak hour background traffic demand will exceed the capacity of the intersection in its current configuration. The future needs for the Trim Road/ Ottawa Road 174 intersection are being assessed as part of the ongoing Ottawa Road 174/ County Road 17 EA study. • During the first two phases of Cardinal Creek Village, it is proposed that traffic will access the development via the proposed Old Montreal Road/minor collector road intersection only. The results of the analysis indicate that traffic generated by the initial phases of Cardinal Creek Village can be adequately accommodated on the adjacent road network at the 2015 build-out year, with the proposed Old Montreal Road/minor collector road intersection projected to operate at acceptable levels of service under this scenario. • Traffic generated by all phases of the proposed subdivision (excluding the two large mixed use blocks abutting Ottawa Road 174) can be accommodated exclusively on Old Montreal Road at the 2021 anticipated build-out year of the development without the need for the proposed connection of major collector road at Ottawa Road 174. Under this future scenario, there may be a need to convert the channelized right-turn lane on the westbound approach to the roundabout at the Trim Road/St. Joseph Boulevard/Old Montreal Road intersection to a free-flow configuration in order to accommodate the increased traffic volumes on this movement during the weekday morning peak hour. This modification would require widening on the east side of Trim Road to provide a northbound merge lane. However, the need for this modification is reduced with the introduction of the proposed intersection of Ottawa Road 174 and the major collector road and the resulting transfer of site generated traffic volumes from the Old Montreal Road corridor to Ottawa Road 174. Therefore, it is recommended that this modification be evaluated further once the timing of the Ottawa Road 174/major collector road intersection is known. • At the 2026 ultimate horizon year of the study, the results of the analysis indicate that there would be a requirement to widen Ottawa Road 174 from two to four lanes between Trim Road and the eastern limit of Cardinal Creek Village, to provide enough capacity for the proposed access intersections to function at acceptable levels of service during the peak hours. One of the main assumptions in the TIS is that additional east- west capacity between Orleans and the communities to the east (Cumberland, Rockland) will be provided through the widening of the existing Ottawa Road 174 corridor. However, the ongoing Ottawa Road 174/County Road 17 (Highway 417/Split to Rockland) EA study and the upcoming City of Ottawa TMP Update in 2013/2014 will assess future travel demand in the area on a regional level and will identify a preferred design alternative that could include widening of the existing corridor or a new east- west corridor east of Trim Road. Therefore, the requirements for the development access at Ottawa Road 174 will be evaluated further with the City of Ottawa as the EA study is advanced and as the details of the proposed mixed-use blocks are finalized. • Under 2026 future traffic conditions, the intersection of Ottawa Road 174 and major collector road will meet the minimum warrants for signalization. Auxiliary turning lanes, including double left-turn lanes on the major collector road approach, will be required.

• Under 2026 future traffic conditions, the three proposed intersections along Old Montreal Road are projected to operate at acceptable levels of service as stop- controlled intersections. Auxiliary left-turn lanes are warranted on the eastbound approach to each intersection. • It is recommended that the internal intersection of the major and minor collector roads be an all-way stop controlled intersection to allow for a designated pedestrian crossing point within the development.

ENVIRONMENTAL IMPACT STATEMENT AND TREE PRESERVATION REPORT A natural heritage system has been identified for Cardinal Creek Village which includes: the Cardinal Creek Valley; the forested slopes south of the hydro line; and, the west, downstream, portion of the North Tributary 3. The natural heritage system proposed is generally consistent with the draft Natural Heritage System identified for the Cardinal Creek Subwatershed Study, with the Natural Heritage System in the Subwatershed Study.

The proposed greenspace system also includes an area of ash forests along the east side of the site and a 15 metre connection between the forested north slope and Old Montreal Road. This corridor, along with the forested lands to the east will assist in providing a linkage to the Ottawa River corridor to the north, although these connections must still cross Ottawa Road 174 to the north of the site. The fresh-moist ash deciduous north forest in the northeast corner of the site is younger than the forests along the north slope but a representation of this forest is also included in the proposed greenspace system.

In addition to the components of the natural heritage system to be retained, portions of the deciduous forest to the northwest of the nursery garden operation and south of the hydro line will also be retained, as will the ash forest adjacent to the downstream portion of the North Tributary. In addition, the provincially rare sugar maple carbonate treed talus, just north of Old Montreal Road, are also proposed for retention.

Proper implementation of the Functional Servicing and Stormwater Management Report by DSEL (2013b) will ensure water quality and quantity leaving the site at least mimics existing conditions.

Certain works are anticipated within the proposed Natural Heritage System or will impact the defined Natural Heritage System (in the east and northeast portions of the site), including:

• A slope stabilization program in the Cardinal Creek Valley; • A realignment of the North Tributary just upstream of the confluence with Cardinal Creek; • A road crossing of the North Tributary to the west of the current commercial nursery garden operation;

3 The upper or east portion of the north tributary is not included due to a lack of fish caught; the lack of features within the channel; and, the adjacent riparian corridor. As an alternative to retention of this portion of the North Tributary as part of an urban development enhancement and rehabilitation measures will be completed on Cardinal Creek and the downstream portion of the North Tributary including addressing areas of erosion.

• A servicing crossing of the North Tributary between the above road crossing and the Cardinal Creek confluence; and, • Encroachment by development into the southwest portion of the cedar coniferous forest. • A series of catchbasins, open ditches, and storm pipes along the eastern edge of the property in order to capture existing drainage from east of the subdivision that is flowing through the site towards the Ottawa River • The proposed stormwater management facility in the northeast corner of the site encroaches on the existing deciduous hedgerows and fresh-moist ash deciduous forest. • The forebay to the south of the hydro line will encroach slightly into the cedar coniferous and maple deciduous forests; and, • Two cascading stream features are proposed within the preserved dry-fresh sugar maple deciduous forest to convey stormwater originating from the proposed development on the plateau down to the proposed stormwater management facility for treatment and, for for the east feature, to a cut-off swale adjacent to the stormwater management facility. These features will require tree removal.

Mitigation measures will be provided to protect the on-site and downstream aquatic habitat, including the Ottawa River. These potential impacts could include increase erosion in the channel from quicker and stronger runoff inputs during storm events, additional nutrient and contaminant inputs from residential activities such as automobile use and maintenance, application of fertilizers, pesticides and herbicides and improper disposal of solvents and other wastes, and direct impacts to the channel for access. Potential downstream sedimentation is also a possible impact with closing of the north portion of the North Tributary.

To minimize impacts on the overall natural environment, the more important ecological features and functions have been retained within the proposed Natural Heritage System and other greenspace components. With proper implementation of the recommended mitigation measures it is anticipated that the construction and operation of the residential and mixed-use subdivision will not have a detectable impact on the retained Natural Heritage System and other greenspace components including watercourses.

The vast majority of development will be on existing cultivated land and service corridors will utilize existing disturbed areas such as the hydro line and Old Montreal Road. To maximize the overall aesthetic and wildlife benefits it is recommended that plantings of native trees and shrubs occur on residential lots and other development blocks that are currently cultivated fields. This, in combination with the extensive retained greenspace areas is anticipated to avoid the potential for significant cumulative effects on the general landscape.

All the community/landform types and flora and fauna species observed on the site are considered common on a local and regional basis, except for a small linear representation of sugar maple carbonate treed talus just north of Old Montreal Road. This maple forest will be retained and protected. The only Species at Risk to be impacted is butternut and a compensation plan will be developed to provide an overall benefit for this species.

Outside of the Natural Heritage System and other greenspace components the required grade raises and cuts, often more than three metres, will generally preclude tree retention. Native trees of local

The EIS concludes that the construction and operation of the proposed residential and mixed-use development will not have a significant impact on the adjacent elements of the Natural Heritage System and other retained greenspace provided the proposed mitigation measures are properly implemented.
