BACKGROUND

 

The Kanata West development area straddles Highway 417 around Scotia Bank Place extending south to Hazeldean Road, north along the Carp River to the urban boundary south of Richardson Side Road.  The total study area comprises 725 hectares (1791 acres) of land.  The site location map is found in Document 1.

 

On March 26, 2003, Ottawa City Council approved the general land use and development principles of the Kanata West Concept Plan (KWCP).  The KWCP is a major component of urban growth in the western portion of the City.  It is planned to include a population of approximately 17,000 persons in 6,300 households, 24,000 jobs and approximately 1 million square metres of commercial space.  The mix of uses includes office, housing, retail, institutional, entertainment and leisure activities.  This scale of development, located between Stittsville and Kanata, is being planned as a mixed-use community.  The Concept Plan includes the transportation network, environmental protection and servicing infrastructure required to support the identified land use plan.  This includes a rapid transit corridor and a number of primary arterials, minor arterial roads, major collector roads, water, sewers, stormwater management and watercourse corridors.

 

Following City Council direction, the draft City of Ottawa Official Plan was revised in March 2003 to reflect the Kanata West Concept Plan, and was adopted by City Council on May 14, 2003.  The Kanata West Concept Plan is reflected in the following Schedules of the City’s Official Plan:

 

Schedule B- Urban Policy Plan

           Enterprise Area

           Mixed Use Centre

           General Urban Area

           Major Open Space

 

Schedule D – Primary Transit Network

           Future Rapid Transit Corridor - alignment to be defined

 

Schedule E – Urban Road Network

           Extension of Campeau Drive Arterial – conceptual (alignment undefined)

           Extension of Huntmar Drive Arterial - conceptual (alignment undefined)

           North-South Arterial - conceptual (alignment undefined)

           Extension of Maple Grove – proposed major collector (west of Huntmar)

           Maple Grove Arterial (east of Huntmar Road) - proposed (alignment defined)

 

Schedule I – Major Recreational Pathways & Scenic-Entry Routes (Urban)

           Extension of the major recreational pathways along Poole Creek and Feedmill Creek

           Identification of Carp River Corridor as major recreational pathway

 

With the approval of the KWCP, developers have been consolidating land ownership in the Kanata West area in preparation for future development.  The majority of landowners within Kanata West have formed a group entitled the Kanata West Owners’ Group Inc. to govern the planning and development of this large development area as one corporate body.  The Official Plan Amendment to recognize the Kanata West Owners’ Group Inc. as a corporation was approved on March 28th by Planning and Environment Committee.  This was confirmed at City Council on April 12, 2006.

 

It was recognized, by both the City and the Kanata West Owners’ Group, that further work was required to facilitate the Plan of Subdivision process in terms of infrastructure planning and process requirements.  The Council approved Carp River Watershed/Subwatershed Study identified the technical study requirements for proposed land use changes in the watershed.  Three concurrent and integrated Class Environmental Assessment studies were initiated in the fall of 2004 to provide a master plan for the road network, servicing (water, sanitary, stormwater management) and river and creek restoration projects as recommended in the Carp River Watershed/Subwatershed Study.

 

The following three Class EA studies were undertaken for the Kanata West Development Area following the Municipal Engineers Association Class Environmental Assessment Process (Class EA):

 

           Kanata West Master Servicing Plan – Stantec Consulting Ltd., CCL/IBI Group

           Kanata West Transportation Master Plan  – Delcan

           Carp River, Poole Creek and Feedmill Creek Restoration Class Environmental Screening Report  – Totten Sims Hubicki with Parish Geomorphoric, Stantec Consulting and Beacon Consulting

 

A Flow Characterization and Flood Level Analysis was also carried out by CH2MHill Canada to update the hydrology and hydraulic model for existing conditions.  CH2M Hill also prepared a post development analysis for future build out of the entire subwatershed area draining into the Carp River, Poole Creek and Feedmill Creek.  This technical analysis supports the three Class EAs for Kanata West.  The existing and post development analysis can be found in an appendix to the Kanata West Master Servicing Plan.

 

The purpose of this report is to summarize the process and recommended infrastructure projects identified in the three Class Environmental Assessment reports.  Although three separate documents have been produced, all the projects have been planned and coordinated as an integrated master plan exercise.  Decisions were made in an integrated and iterative process throughout the course of the studies.  Through this iterative discussion and consultation many additional tasks and investigations were undertaken to ensure compatibility between the various infrastructure requirements. 

 

DISCUSSION

 

The City of Ottawa and the Kanata West Owners’ Group (KWOG) are co-proponents for the Class Environmental Assessments.  Several plan of subdivision applications were being submitted at the same time as commencing the Class EAs.  As such, the KWOG and the City proceeded to follow the integration provision of the Class EA process.  It recognizes the benefits of integrating approvals under the Environmental Assessment Act and the Planning Act.  Any project which would otherwise be subject to the Municipal Class EA, that meets the intent of the Class EA (Section A.2.9) and receives approval under the Planning Act is considered to be a Schedule A project and may proceed to construction.

 

However, as a result of comments received from the Ministry of Environment, Environmental Assessment Approvals Branch, the Planning Act and Environmental Assessment Act requirements were separated and the development applications and infrastructure studies proceeded independently.  The Plans of Subdivisions are being approved through the Planning Act.  The infrastructure and watercourse restoration projects are fulfilling the Environmental Assessment Act requirements through the Class Environmental Assessment process as follows:

Kanata West Transportation Master Plan

 

The Kanata West Land Owners’ Group, representing the major landowners within the Kanata West Development Area has completed a Class Environmental Assessment (EA) Study for the major road network required to provide appropriate transportation service to the lands designated for urban development in the Kanata West Concept Plan.  Ottawa City Council approved the Kanata West Concept Plan in March 2003, and the major road network identified at that time included:

 

           Campeau Drive Extension:  Didsbury Road to Palladium Drive;

           Maple Grove Road Widening:  Terry Fox Drive to Huntmar Drive;

           Relocated Maple Grove Road:  West of Huntmar Drive;

           Huntmar Drive Widening and Extension:  Palladium Drive to Hazeldean Road; and

           North-South Arterial:  Palladium Drive to Hazeldean Road.

 

The concept plan also identified the extension of the West Rapid Transit corridor west of Kanata Centrum through the Kanata West Development Area (KWDA) to Hazeldean Road.

 

While recognizing that the rapid transit corridor will require an Individual Environmental Assessment, alternative corridors were evaluated and a preferred corridor identified as part of the Master Plan (Phases 1&2) to ensure that the best combinations of road and rapid transit links were identified for long-term corridor protection.

 

Alternative Transportation Solutions

Drawing on the recently completed Transportation Master Plan (2003), and the updating of the technical analysis in support of the Kanata West Concept Plan (2002), the preferred alternative solution to meet the long-term transportation system requirements of the Kanata West Development Area, as approved by Ottawa City Council, includes a combination of TDM/TSM measures, improved transit (including rapid transit), road widenings and new roads.

 

The principal elements of the future transportation network include:

 

           Rapid transit corridor from Kanata Centrum west to Scotia Bank Place and south to Hazeldean Road;

           Extension of Campeau Drive as a four-lane arterial (4-UAD) from Didsbury Road to Palladium Drive;

           Widening of Maple Grove Road to four-lanes (4-UAD/4-UAU) from Terry Fox Drive to Huntmar Drive;

           Widening of Huntmar Drive as a four-lane arterial from Palladium Drive to Maple Grove Road;

·                      Extension of Huntmar Road as a two/four lane arterial from Maple Grove Road to Hazeldean Road; and

           Construction of the North-South Arterial as a four-lane arterial from Palladium Drive to Hazeldean Road; and

           Stittsville Main Street extension as a two-lane major collector connecting the North-South Arterial to the proposed Jackson Trails subdivision, west of the KWDA.

 

Alternative Transportation Design Concepts

Rapid Transit Corridor:  North of Highway 417 two conceptual rapid transit corridors were identified, one north of and one south of Feedmill Creek.  Over Highway 417 and within the Scotia Bank Place lands to the south, one alternative location was identified, while further south between Palladium Drive and Hazeldean Road three alternatives were evaluated, representing central, easterly and westerly corridor locations.

 

Campeau Drive Extension:  Two alternative corridors were evaluated each representing a potential pairing with one of the rapid transit alternatives.

 

Maple Grove Road Widening:  Three alternative widenings were identified based on equal widening on either side of the existing centerline or widening totally to the north or south of the existing right-of-way.

 

Huntmar Drive Widening:  As with Maple Grove Road, three widening alternatives were identified, equally about the existing centerline or totally to the east or west of the existing right-of-way.

 

Huntmar Drive Extension:  Only one alternative was identified for the extension of Huntmar Drive within the proposed Mattamy Homes Subdivision south of Maple Grove Road, as the end points of this link at Maple Grove Road and at Hazeldean Road were already fixed.

 

North-South Arterial:  Two alternative corridors were identified.  One intersected with existing Huntmar Drive north of Maple Grove Road while the second intersected with the Huntmar Drive Extension within the proposed Mattamy Homes Subdivision, south of Maple Grove Road.

 

Stittsville Main Street Extension:  Two alternatives, differing in length only, were evaluated in conjunction with one or other of the two North-South Arterial alternatives.

 

Evaluation of Transportation Alternatives

The alternatives for each link in the transportation network were evaluated using a paired comparison evaluation approach, based on four broad criteria groups:  Social Environment, Physical Environment, Biological Environment and Transportation Environment, with each group further broken down into a number of criteria.

 

The result of the evaluation process was a preferred network comprised of the following projects recommended for approval as per Recommendation 1 of this report:

 

·          Campeau Drive Extension/Rapid Transit Corridor:  In combination with, and generally parallel to the conceptual rapid transit corridor north of Feedmill Creek, the preferred alignment for Campeau Drive reflects an adequate amount of physical separation to enable appropriate blocks of residential development to occur in proximity to a future rapid transit station with a resultant alignment that is considered to be more harmonious with the residential land use within which it will be located.  The conceptual corridor for the Transitway has been identified as part of this process to address and identify an integrated transportation system, however, the final alignment for the transitway will be evaluated during the East-West Light Rail Corridor Individual EA, currently under way.  (FIGURE 1, Document 2).

 

·          Maple Grove Road Widening:  Widening about the centerline was preferred in order to tie into the existing alignment at Terry Fox Drive, to equalize property impacts, and to facilitate right-of-way acquisition (FIGURE 2, Document 2).

.

·          Huntmar Drive Widening:  Again, widening about the centerline was preferred to tie into the existing four-lane cross-section north of Palladium Drive, to equalize property impacts and to facilitate right-of-way acquisition (FIGURE 3, Document 2).

 

·          North-South Arterial/Rapid Transit Corridor:  The alternative that results in a corridor north of Maple Grove Road as a boundary between residential and mixed-use land uses, while removing the major intersection with Huntmar Drive from within residential development south of Maple Grove Road, was preferred.  In conjunction with the preferred centrally based conceptual corridor for the rapid transit corridor south of Palladium Drive, the combined corridors will provide an acceptable separation between the proposed Mattamy Homes and Richcraft Home residential development south of Maple Grove Road (FIGURE 4, Document 2).

 

·          Stittsville Main Street Extension:  The preferred North-South Arterial results in the shorter of the two alternatives for the relocated Maple Grove Road to the west being preferred (FIGURE 5, Document 2).

 

Kanata West Master Servicing Plan

 

The Kanata West Master Servicing Plan serves as an update to the 2002 Concept Plan prepared by FoTenn Consulting.  The objective of the study is to provide, at a macro level, a servicing plan for the Kanata West Development Area (KWDA) identifying an internal servicing scheme for water, sanitary and stormwater that supports the land uses and development densities within the subject area.  The principal recommendations of the master servicing study are discussed below.

 

Sanitary Servicing Alternatives

The sanitary servicing plan for the Kanata West area identified the following main components of the system to be investigated: 1) Off-Site Wastewater Outlet; 2) Internal Pumping Station and Associated Gravity Sanitary Sewers; 3) Temporary Forcemain; 4) Gravity Sewer to service Hazeldean Road and the southern portion of KWDA; and, 5) Signature Ridge Pumping Station Upgrade.  A description of the alternatives considered for each component is described below. 

 

Off-site Wastewater Outlet Alternatives:  Two options were considered to outlet the wastewater system for Kanata West to its designated outlet, the Glen Cairn Collector Sewer: 1) Gravity; and 2) a Combination of Pumping and Forcemain.  One gravity alignment was identified and two forcemain alignments were considered.  The locations were generally based on the available corridors through the existing communities to the east, which lies between Kanata West and the designated outlet.  The three alternative outlet alignments are:

·           Gravity sewer (tunnel) along the 417 corridor to the Tri Township sewer

·           A forcemain along the 417 corridor from Silver Seven Road to the Glen Cairn Collector sewer east of Eagleson Road

·           A forcemain along Katimavik Road and Palladium Drive from Silver Seven Road to the  Glen Cairn Collector Sewer east of Eagleson Road

 

Internal Servicing Alternatives:  Three potential locations for the Kanata West Pumping Station were identified with associated trunk sewer corridors connecting to the existing First Line Road Sewer: 1) Silver Seven Road at Hwy 417; 2) Hwy 417 east of Carp River; and 3) Maple Grove Road west of the Carp River (two proposed trunk sewer alignments). 

 

Temporary Pumping Station Alternatives:  Three potential alignments were considered for a temporary forcemain, which will be required to service the initial phases of development.  The locations are based on available corridors through the existing community to reach the temporary outlet, the Stittsville Collector Sewer.  The three alternative forcemain alignments are:

·           Maple Grove Road, Huntmar Road and Iber Road to the temporary outlet, the Stittsville Collector Sewer at the south end of Iber Road

·           South, parallel to the west side of the Carp River, through the proposed development to the Glen Cairn stormwater pond, east to Terry Fox Drive, and southerly along Terry Fox Drive to the Stittsville Collector.

·           East on Maple Grove Road to Terry Fox Drive and southerly on Terry Fox Drive to the Stittsville Collector.

 

Huntmar Road Gravity Sewer:  Three potential alignments were considered for a gravity sewer, which will service currently unserviced lands on Hazeldean Road and provide the potential to decommission several small existing pumping stations along the northern limit of the Village of Stittsville.  The three alternative alignments are:

·           Maple Grove Road from the proposed pumping station at Huntmar Road, Huntmar Road to Hazeldean Road at Iber Road

·           Maple Grove Road to south of Poole Creek, southerly along Poole Creek to the transit corridor, southerly along the transitway to Hazeldean Road, and Hazeldean Road to Iber Road

·           South from Maple Grove Road Pumping Station through the proposed development to Hazeldean Road, and west on Hazeldean Road to Iber Road

 

Signature Ridge Pumping Station:  Two alternatives were considered for the Signature Ridge Pumping Station: 1) Upgrade station to satisfy drainage requirements, or 2) Rebuild.  These alternatives were considered because of the significant amount of existing infrastructure that depends on Signature Ridge Pumping Station for an outlet and the proximity of this pumping station to the northeast portion of the Kanata West development area.

 

Evaluation of Sanitary Alternatives

The alternatives for each component of the wastewater system were evaluated and ranked using a standard pair-wise comparison methodology, based on four broad criteria:  Constructability/Functionality; Economy, Caring and Healthy Communities and Natural Environment, with each group further broken down into a number of criteria. 

 

The results of the evaluation process was a preferred sanitary servicing system comprised of the following projects recommended for approval as per Recommendation 1 of this report:

 

Off-Site Wastewater Outlet - Permanent Twinned Forcemain to the Tri Party Collector.

The second forcemain alternative, the Katimavik Road alignment, was selected as the permanent outlet for the new Kanata West Pumping Station and associated trunk sewer linking it to the Tri Party Collector.  This option offers the most flexibility for internal servicing design, uses a lower road classification corridor which simplifies routine maintenance operations and provides maximum separation distance from the ANSI (Area of Natural or Scientific Interest) located in the 417 corridor east of Terry Fox Drive (FIGURE 6, Document 2). 

 

Internal Servicing  - Kanata West Pumping Station at Maple Grove Road, west of Carp River and associated trunk sanitary sewer from Silver Seven along Carp River between Maple Grove and Palladium Drive.  Option 3 (FIGURE 7, Document 2) was selected as it will be designed with the capacity to allow decommissioning of up to eight small public and private pumping stations along Hazeldean Road.  Temporarily the Kanata West pumping station will outlet to the Stittsville Collector Sewer via a temporary forcemain in Huntmar Road and Iber Road (Alternative 1).  This temporary forcemain is designed to accommodate 200 l/sec (approximately 3,000 units).  The location of the new pumping station is in close proximity to Stormwater Management Ponds 4 and 5 providing an opportunity to provide catastrophic failure protection to the new pumping station in the form of a gravity overflow.

 

Huntmar Road Gravity Sewer:  Alternative 1 along Huntmar Road, east along Maple Grove to the new Kanata West pump station was selected as the preferred alignment (FIGURE 8, Document 2).  This gravity sewer will collect flow from several minor internal sanitary sewers and directs this flow to the new pumping station location.  The inclusion of this north-south sewer is a key element in eliminating the need for double pumping within Kanata West and also facilitates the decommissioning of the Corel Centre siphon.

 

Signature Ridge Pumping Station:  An upgraded Signature Ridge Pumping Station (SRPS) was selected as the preferred option to service all the Kanata West lands north of the Queensway, the existing urban area north of the Queensway currently proposed to drain to the SRPS, and the Broughton/Richardson and Interstial lands (FIGURE 9, Document 2).  Presently the City is undergoing a SRPS and Forcemain Upgrades Feasibility and Preliminary Design Studies to determine the best alternative for the upgrade.  This study is expected to be completed in Spring of 2006.

 

In order to implement this servicing plan effectively it will be necessary to provide regular flow monitoring at the Stittsville Collector Sewer, the Hazeldean pumping station, and the Signature Ridge Pumping station, to ensure that the ultimate works are designed and constructed in time to allow a continuous building program throughout the build out of the Kanata West development area.

 

The preferred sanitary system provides a flexible cost effective servicing scheme that allows for phased construction of the new wastewater infrastructure by making use of residual capacity in the existing infrastructure and maximizing the potential of this existing infrastructure.  The ultimate servicing scenario also increases the efficiency of the City’s overall wastewater system by minimizing the number of new pumping stations and facilitating the ultimate decommissioning of up to eight existing public and private pumping stations and one siphon.  The proposed sanitary sewer system has been designed in conjunction with the storm sewer system and water system to provide a coordinated cost effective system with maximum flexibility to accommodate the orderly and staged development of the entire Kanata West area.  The proposed sanitary sewer system also recognizes inefficiencies in the existing sanitary sewer system, outside the Kanata West development area, and is designed to provide flexibility in the ultimate system to cost-effectively maximize the efficiency of the overall wastewater system.

 

Watermain Alternatives

The objective of the water supply assessment is to update the "internal" water servicing requirements within the approved Kanata West Concept Plan and determine the operability of the system under different demand scenarios.  Watermain corridors were identified and linked with transportation corridors in order to reduce the construction impacts of new utility corridors. All watermains are proposed to be located within identified transportation corridors.

 

The preferred wastewater system is comprised of the following projects recommended for approval as per Recommendation 1 of this report:

 

A 610mm watermain loop is proposed to be located within the north south arterial corridor from Hazeldean to Huntmar, north within the Huntmar right-of-way to Campeau Drive, east within the defined Campeau Drive right-of-way tying into the existing watermain at Campeau and Terry Fox.  This sizing considers peak daily demands, fire flow requirements and reliability needs (FIGURE 10, Document 2).  This watermain will provide a strong loop through the proposed development area, and most importantly, will provide appropriate redundancy for the major transmissions on Hazeldean Road.  This 610mm watermain will provide sufficient conveyance capacity between Kanata and Stittsville to allow flexibility in operating Pressure Zone 3W by allowing water pump station discharge pressures to be reduced while maintaining adequate pressures in the Stittsville area. 

 

A 406mm diameter watermain at south end of the proposed Huntmar, within the proposed right-of-way and looped 305mm diameter watermains within defined road right-of-way as shown in the figure, will be needed in different parts of the Kanata West Concept Plan area to provide adequate domestic and fire flow demands.  Other looped pipes will be required within individual growth areas, and it is expected that these pipes will range in size from 152mm to 305mm in diameter (Figure 10, Document 2).

 

Stormwater Management Alternatives

The Master Servicing Plan confirmed the need for water quality control for new developments in order to limit the transport of contaminants to the receiving watercourses.  Based on the recommendations of the Carp River Watershed/Subwatershed Study (CRWSS) and utilizing the Ministry of Environment Stormwater Management Planning and Design Manual Guidelines, end-of-pipe wet ponds are required to meet the water quality design criteria.  Four stormwater management alternatives were identified: 1) Do Nothing; 2) 10 pond option presented in the CRWSS; 3) 5 pond option presented in the KWCP and CRWSS; and 4) hybrid of options 2 and 3 which include, 5 ponds outletting to the Carp River and 2 ponds outletting to Feedmill Creek. 

 

Evaluation of Stormwater Management Alternatives

The four alternatives were evaluated using a standard pair-wise comparison methodology, based on four broad criteria:  Constructability/Functionality; Economy, Caring and Healthy Communities and Natural Environment, with each group further broken down into a number of criteria. 

 

Based on the results of the evaluation process, option 4 was selected as the preferred stormwater management servicing plan for the KWDA. This option offers the most flexibility and phasing opportunities while providing an economical solution.  The solution also meets the requirements of the Carp River Watershed/Subwatershed study.  The preferred stormwater management system consists of the construction of the following seven end-of-pipe wet pond facilities (FIGURE 11, Document 2) recommended for approval as per Recommendation 1 of this report:

 

§         Pond 1 adjacent to the Carp River and downstream of Campeau Drive will service the future residential lands between the Carp River, Campeau Drive and Huntmar Road, as well as an area of extensive employment between Feedmill Creek and Campeau Drive.  Normal and 100yr water levels in the pond are 92.70 and 93.96, respectively.

§         Pond 2 is proposed just upstream of the confluence of Feedmill Creek and the Carp River on the south bank and will service future extensive employment and high profile employment lands between Feedmill Creek and Highway 417. Normal and 100yr water levels in the pond are 93.25 and 94.23, respectively.

§         Pond 3 is proposed on the north bank or the Carp River between the future transitway and Highway 417.  It will service low density business park and community retail lands between Didsbury Road and the Carp River.  Normal and 100yr water levels in the pond are 92.90 and 94.20, respectively.

§         Pond 4 adjacent to the Carp River is proposed just upstream of Palladium Drive and downstream of the Poole Creek confluence with the Carp River and will service a mixed use area bound by Pool Creek, Palladium Drive and the Kanata West Community Boundary. Normal and 100yr water levels in the pond are 93.25 and 94.74, respectively.

§         Pond 5 is proposed upstream of the confluence of Poole Creek and the Carp River along the south-west bank of the Carp River.  Pond 5 will service residential and retail developments between Poole Creek, the Carp River and Hazeldean Road.  Normal and 100yr water levels in the pond are 93.44 and 94.94, respectively.

§         Pond 6 is to be located north-east of Feedmill Creek at the intersection with Huntmar Road and will service business park and extensive employment developments. Normal and 100yr water levels in the pond are 98.00 and 98.94, respectively.

§         Pond 7 is proposed south of Highway 417 and west of the future north-south arterial and will service business park and extensive employment lands. Normal and 100yr water levels in the pond are 102.20 and 102.92, respectively.

 

As part of all stormwater management facility designs, a detailed maintenance and monitoring program is required to maintain the operational efficiency and functionality of the facility, while monitoring its long-term performance in relation to the proposed design, as stipulated in the MOE Certificate of Approval for each facility. 

 

The City's "Ottawa Sewer Design Guidelines (January 2005)" were used to design the storm sewer system associated with the stormwater management facilities.  The minor system is designed according to either a 5 year (local roadways) or to a 10 year level of service (arterial roadways) without surcharge.  The minor system is also designed to operate under limited surcharge in the 100 year event such that a minimum clearance of 0.3m exists between the building footings and the hydraulic grade line (HGL).  The alignment and size of the trunk sewers were established applying the City's guidelines considering the proposed road layout, tributary areas to respective sewers and issues pertaining to the 100 year hydraulic gradeline elevations. 

 

The storm servicing system to support the stormwater management solution is illustrated on Figure 12 of Document 2.  The preferred storm sewer projects associated with each stormwater management facility are being recommended for approval as per Recommendation 1 of this report.  To service the area adjacent to the Carp River, large diameter sewers laid at flat grades were required.  The hydraulic grade line analysis completed provides protection for all units in accordance within the Kanata West development meeting City design guidelines.  The preferred trunk sewer sizes and locations have all been designed in accordance with the City of Ottawa design guidelines.  The preferred cover requirement of 2.0 m is not met in all locations, specifically where the grade falls towards the Creeks and River. To provide a gravity connection from the foundation drains to the storm sewer, a grade raise in combination with more exposed foundation or a modified building structure (i.e. walkouts, split level homes) may be needed.


 

Existing Condition And Post Development Hydrology And Hydraulic Analysis

 

A hydrologic and hydraulic analysis has been completed for the Carp River, Poole Creek and Feedmill Creek tributaries. This analysis included all areas upstream of the Village of Carp, including the proposed Kanata West Development Area and future development as identified in the City of Ottawa Official Plan. The purpose of the analysis was intended to understand the cumulative impact of the proposed transportation network, the land use, servicing requirements and restoration project for the Carp River, Poole Creek and Feedmill Creek within Kanata West.  The analysis needed to address the concern that proposed changes as a result of the Kanata West development and associated infrastructure, and Carp River restoration project may result in an unacceptable impact to flood levels and flows in the Upper Carp River watershed.

 

The analysis was completed in three steps. The initial step was to characterize the existing flows and water levels in the river systems based on current land use, topography, soil cover, hydraulic structures, and surveyed cross-sections of the channels. This base condition was then compared with the condition under the full build out of the Kanata West community including the revised flood corridor, channel restoration, new road crossings, and altered drainage patterns and discharges to the Carp River, Poole Creek and Feedmill Creek. Thirdly, the analysis was extended to include the complete ultimate build out of the Official Plan including the development of the Broughton lands, the partial floodplain encroachment proposed under the Terry Fox extension, and the proposed new Hazeldean crossing of the Carp River.

 

The methodology for the hydrologic analysis made use of the XP-SWMM and QUALHYMO model to generate inflow hydrographs to the various river.  The hydraulic analysis for the Carp River used the unsteady state option of HECRAS. This takes into account the effect of channel storage and routing along the flat gradient of the channel. The steady state flow option of HECRAS was applied for Poole Creek and Feedmill Creek.  The inflow hydrographs were then routed in a hydraulic model HECRAS to generate computed water levels, flows and velocities. Flows and water levels were checked by using actual water levels measured during the September 9, 2004 storm events, as well as a sensitivity analysis of hydrologic parameters.

 

The results of the analysis indicate the Kanata West Development and floodplain encroachment will result in an increase of 0.04m increase in the 100 year water level immediately upstream of Richardson Side Road, and a reduction in water level of 0.12m at Highway 417.  The full build out of the Official Plan and floodplain encroachment will result in an increase of 0.11m upstream of Richardson Side Road, and no change in water level at the Highway 417.  Water levels upstream of Palladium Drive will increase by a maximum of 0.07m as a result of Kanata West build out, and a maximum of 0.18m as a result of the complete build out of the Official Plan. The full build out of the Official Plan and floodplain encroachments will result in a maximum increase of 0.04m downstream of Richardson Side Road in the rural area.  Predicted flow velocities downstream of Richardson Side Road will be below erosion thresholds

 

The Mississippi Valley Conservation Authority has reviewed and supports the hydrologic and hydraulic analysis that has been completed.

 

Carp River, Poole Creek, And Feedmill Creek Restoration

 

The Council approved Carp River Watershed/Subwatershed study recommended restoration and enhancement of the Carp River, Poole Creek, and Feedmill Creek.  The purpose of the Class Environmental Assessment study was to develop, evaluate and recommended preferred rehabilitation alternatives for Carp River, Poole Creek and Feedmill Creek within the Kanata West development area.  The need for the restoration was identified in the subwatershed study.  This section of the Carp River is very degraded as it has been subject to historical straightening which has resulted in significant sediment accumulation on the channel bed.  This has resulted in degraded water quality and aquatic habitat.  Poole Creek and Feedmill Creek support tolerant cold water fish community and diverse warm water fishery.  However, both creeks are experiencing bank undercutting and erosion which are impacting the stability and function of the stream channel in certain sections.  The accumulated sediment build up in the Carp River is impacting the mouths of Poole and Feedmill Creeks.

 

The purpose of the Class EA study was to develop a preferred alternative and conceptual design for the Carp River including Poole Creek and Feedmill Creek.  The conceptual design of the Carp River is to be situated within the proposed 100 metre minimum corridor as outlined in the Carp River Watershed/Subwatershed study. 

 

Further field investigations were carried out in the areas of terrestrial, aquatic, and fluvial geomorphology.  The existing conditions of the creek corridors were characterized building upon the work carried out in the watershed/subwatershed study.  The fieldwork findings and analysis confirmed the degraded condition of the Carp River and problematic areas within the Poole Creek and Feedmill Creek. 

 

Restoration Alternatives

Alternatives were developed using a two-phased approach.  The first phase involved the development of preliminary alternatives and a coarse screening process.  The second phase refined the preferred preliminary alternative to generate more detailed alternatives.  The physical constraints associated with the Carp River limited the options available, however the following alternatives were considered for all three watercourses:

 

           Do Nothing

           Harden Channel (concrete lined portions of channel, armourstone bank enhancements, rip rap revetments)

           Natural Channel Design

 

Based on the preliminary screening, it was determined that the Do Nothing and Harden Channel options would not meet the project objectives.  The Natural Channel Design preliminary alternative was selected and further refined into two more detailed alternatives:

           Local Restoration – provides the opportunity for enhanced geomorphic or environmental conditions in identified areas of need; and,

           Full Restoration – provides for enhanced geomorphic and environmental conditions.  This tends to be a large-scale work, where the channel can be moved, realigned and designed to incorporate more channel elements (pools and riffles).

 

Both alternatives were evaluated for the Carp River.  Based on observed degraded conditions of the Carp River throughout the study area, local restoration opportunities would not serve to sufficiently address the issues or project objectives.  Stabilization and enhancement requirements/opportunities exist throughout the entire study area for the Carp River.  Using the principles of natural channel design, the desired outcome for a full restoration would include:

           Increased sinuosity and river stability

           Reduced channel width by 20-25%

           Riparian enhancement and biodiversity

 

The full restoration alternative will meet the study objectives with respect to sediment transport, erosion control, flow conveyance/flow regime and environmental enhancement.

 

Poole Creek and Feedmill Creek were evaluated for both the local and full restoration alternatives.  Based on the observed high quality characteristics of Poole Creek and Feedmill Creek, local restoration would provide the opportunity to enhance and stabilize the areas of concern while leaving other areas undisturbed.

 

Carp River Preferred Alternative

As per Recommendation 1 of this report, the preferred full restoration alternative for the Carp River is being recommended for approval. (FIGURE 13, Document 2).  The preferred restoration project includes a change to the channel cross-section and planform as well as the following design elements:

 

           Increased sinuosity (channel length) by approximately 10%

           Reduction in channel cross-section

           Planform will accommodate ecological features such as ponds and deltas

           Proposed “nested” set of channels to improve sediment transport

           Narrow section also permits the use of more varied substrate

           Use “reference’ section near Feedmill confluence

           Upstream area may involve some bed treatment to raise invert and increase local gradient

           Incorporate gravel-cobble shoals and some pools to vary substrate and offer more diverse habitat

           Plant riparian vegetation along corridor to restore corridor function and create wildlife habitat

           Pedestrian pathway throughout the entire length of the river as part of larger regional pathway system and local system

 

The Carp River corridor varies from the existing 75 metre to intervals of 100 m, 150m, 200m, and 250 metres.  The Carp River flood plain, in many locations, is greater than 100 m and downstream (north) of Highway 417 the existing flood plain width is narrower than 100 m.  The floodplain encroachments represent approximately 28 hectares and 15% total loss of existing flood plain storage for the reach between Richardson Side Road and Hazeldean Road.


 

Poole Creek Preferred Alternative

Local improvements along the Poole Creek corridor is being recommended for approval as per Recommendation 1 of this report.  Along Poole Creek, there are four areas along the creek corridor that require local improvements as illustrated on Figure 14 of Document 2.  Local improvements include channel realignment, removal of island and narrowing of channel, removal of debris and old bridge, valley wall treatment, creation of a delta marsh and riparian plantings.

 

Feedmill Creek Preferred Alternative

Local improvements along Feedmill Creek is being recommended for approval as per Recommendation 1 of this report.  For Feedmill Creek, there are four areas along the creek corridor that require local improvements as illustrated on Figure 15 of Document 2.  Local improvements include channel realignment, increased sinuosity, aquatic connections to the Carp River, local bank treatment and riparian plantings.

 

A monitoring plan will be prepared and implemented to evaluate the performance of the design and mitigation techniques over the short and long term.  

 

RURAL IMPLICATIONS

 

The Kanata West development area is situated upstream of the rural area.  The development area drains into the Carp River that flows downstream into the adjacent rural area.  Through public consultation, rural residents expressed concerns related to downstream impacts of urban development as it relates to flows and velocities in the Carp River.  In order to address these concerns, additional investigations and analysis was undertaken.  Sixteen (16) additional cross sections were surveyed and structure information was updated.  QUALHYMO was used to generate hydrographs and the existing conditions model was updated. 

 

The results of the post development analysis show that there is a maximum 0.02m (20 mm) increase in 100 year water level downstream of Richardson Side Road with a 0.01 m increase downstream of March Road.  Upstream of Huntmar Road (east side), a 0.04m increase in 100 year water level is shown under future built out conditions.  The water level increases are not deemed significant.  The 100 year water levels at Carp Road match water levels under existing conditions.

 

The low flow velocities for existing and future conditions were modeled for the 2, 5 and 10 year storm events to assess erosion potential.  Consideration was given to the soils and bank types along the watercourse.  The banks are primarily clay and loam and the modeled velocities do not approach velocities that would create erosion for this type of bank.

 

ENVIRONMENTAL IMPLICATIONS

 

The recommended projects have been identified through a Class Environmental Assessment process.  As such, the environmental conditions, impact assessment, mitigation and monitoring measures have been accounted for in determining the preferred alternatives. 

 

The Carp River, Poole Creek and Feedmill Creek restoration project will provide an overall environmental enhancement to the feature and function of the river system in terms of aquatic habitat improvements, terrestrial corridor improvements and river function as it relates to conveyance and sediment transfer. 

 

CONSULTATION

 

The consultation program included the following activities fulfilling the consultation requirements specified in the MEA Class EA document for Schedule B and C projects:

 

           Establishment of core Study Team to guide and prepare Class EAs

           Bi-weekly Study Team meetings

           Regular meetings with the three Ward Councillors throughout the course of the study

           Three Public Meetings

           Individual meetings with individuals, interest groups and community organizations

           On-going response to public inquiries and questions

           Individual and collective meetings with provincial and federal agencies to discuss technical information requirements and comments

 

The main concerns expressed by the public were associated with the Carp River restoration project and the proposed floodplain encroachments.  The Sierra Club, Ottawa Riverkeeper, Friends of the Carp, Greenspace Alliance (“the Coalition”) and other individuals primarily expressed these concerns.  Additional technical work was commissioned and information was presented at additional meetings with interest groups and individuals to discuss their concerns.

 

All technical and policy related comments received from the Provincial agencies have been addressed by the Study Team (MVC, City of Ottawa Staff and the KWOG representatives and consultants).  A series of meetings took place on December 5, 2005, March 7, 2006 and March 20, 2006 to resolve comments received by the agencies.  These meetings resulted in concurrence between the Study Team and the agencies regarding their concerns.  The additional technical information and analysis agreed to by the agencies has been incorporated into the Class EAs such that the City and KWOG can proceed with completing the Class EA process.

 

The three Class Environmental Assessments will be finalized after City Council approves the recommended projects for the Kanata West Development Area.  Notices of Completion will be published for the three Class EAs notifying the public of the availability of the reports and the 30-day public review period.

 

FINANCIAL IMPLICATIONS

 

Infrastructure Projects

The roads and servicing infrastructure, identified in the Council approved Kanata West Concept Plan and refined in the Class Environmental Assessment, for the most part will be designed and constructed by the Kanata West Owners Group.  There will be an operational impact to the City as this infrastructure is put in service through the regular development process. Several of the projects as referred to above are listed in the City's Development Charge By-Law and will be subject to budget approval by City Council through the annual budgeting process and/or through City's approved Front-Ending Policy in conjunction with the City approved Long Range Financial Plan. It should be noted that stormwater management ponds and trunk storm sewers were requested by the Kanata West Owner Group to not be included in the Development Charge By-Law and as such are the financial obligation of the Kanata West Owners Group and they not eligible for Development Charge funds.  Development charges do not apply to the watercourse restoration projects. As such, the funding mechanism for the watercourse restoration project is described below.

 

Watercourse Restoration Project

The Kanata West Owners’ Group will pay for the restoration works associated with Poole Creek and Feedmill Creek.  The Kanata West Owners’ Group will also pay for the detailed design contract for the Carp River restoration project.  The construction of the Carp River restoration project is estimated to cost $5,000,000.00.  A cost sharing formula has been established whereby the total costs of the project would be distributed as follows:

 

           30% - City

           45% - adjacent landowners

           25% - remaining Kanata west landowners

 

The Carp River restoration project benefits Ottawa residents at large as well as the Kanata West and adjacent developments.  The landowners would pay 70% of the restoration costs with 30% of the costs attribute to the City.  Based on this cost sharing formula, the cost of the restoration project would be distributed as follows:

 

           $1,500,000 - City

           $2,250,000 - adjacent development

           $1,250,000 - remaining Kanata West landowners

 

The Carp River Restoration project is currently defined in capital account #903940.  The balance of the City's portion of the restoration project will be established through the 2007 budgetary process.

The first Public Meeting was held on 20 December 2004 from 7:00 p.m. to 9:00 p.m. at 2135 Huntley Road, Stanley’s Corners, the former Goulbourn Township Municipal office for the Road Network EA and the subdivision process.  A Notice concerning the study commencement and the public meeting had been placed in the Kanata Kourier, (Dec 10 and 17), West Carleton Review (Dec 10 and 17, Stittsville Signal (Dec 10 and 17), Stittsville News (Dec 8 and 15) prior to the public meeting.  On site signs announcing the Public Meeting were posted on lands subject to development applications; 1560 and 1620 Maple Grove Road, 325 Didsbury Road and 5831 Hazeldean Road (now 1776 Maple Grove Road).  In addition the Notice was mailed to all Kanata West landowners, landowners within 120 metres of the Kanata West boundary and all community associations in Kanata, West Carleton and Goulbourn.

 

The meeting was a combination of an open house and a presentation format followed by questions from the audience.  The purpose was to provide information and solicit comments on:

·                      the need for the transportation facilities;

·                      existing environmental conditions;

·                      alignment alternatives;

·                      transportation impacts and requirements; and

·                      planning and EA approval process.

 

Approximately 50 people attended the meeting.  Transportation-related comments focused primarily on the urgency to have some of the proposed roads, in particular, the Huntmar Drive Extension, built as soon as possible.  Comments regarding the land development tended to focus on the provision of parks and recreational facilities.  These comments were incorporated into the development of environmental values that were applied during the Class Environmental Assessment Process. 

 

Public Meeting #2

 

The second public meeting was held on 20 June 2005 from 5:30 p.m. to 9:00 p.m. at the Glen Cairn Community Centre, 186 Morena Avenue, Kanata.  This meeting was a combined meeting to provide information on all of the projects related to the KWDA including status of planning applications as well as all three Class Environmental Assessment studies.  The public meeting was the first mandatory meeting for Schedule B undertakings for the Master Servicing and the Carp River, Poole Creek and Feedmill Creek EAs.  The public meeting was the second mandatory meeting (end of Phase 3) for the Transportation Road Network Master Plan Class EA as the projects identified fall under a Schedule C undertaking.  The purpose of the public meeting was to provide information and solicit comments regarding:

 

·                      the need for the infrastructure facilities;

·                      existing environmental conditions;

·                      alternatives considered;

·                      impacts and mitigation measures;

·                      the servicing (water, sewer, storm water) networks;

·                      concept and functional plans for

-          North-South Arterial

-          Campeau Drive Extension

-          Huntmar Drive Extension

-          Maple Grove Road Widening

-          Stormwater Management Facilities

-          Sanitary Pump Station and Forcemain

-          Proposed river and creek structures; and

-          Carp River, Poole Creek and Feedmill Creek Restoration Concept Plans

 

Notices of the public meeting were placed in daily and weekly newspapers prior to the meeting.  The Notice appeared in the Ottawa Citizen on 10 June 2005 and 18 June 2005 and in the local newspapers, Kanata Courier, Stittsville News, and West Carleton Review Weekender the week of June 13, 2005.  In addition, Notices were sent to adjacent landowners, community associations and attendees from the first meeting. 

 

The meeting was a combination of an open house and a presentation format followed by questions from the audience.  Approximately 50 people attended and the primary comments were related to the proposed Carp River Restoration and how the development of the area would affect flooding, drainage, and adjacent communities.  These comments were incorporated into the development of mitigation measures where appropriate and resulted in additional modeling being undertaken to validate the predicted downstream effects. 

 

Community Association Meeting

The Stittsville Village Association (SVA) requested an additional information meeting.  The Study Team attended their July 14 meeting and presented the material from the June 20 meeting.  The comments from the SVA and those in attendance at the meeting focused on the land use and development designations within the KWDA. 

 

Interested Groups and Individuals

Meetings were also held with individuals, landowners and interested groups, such as the Friends of the Carp and the Ottawa River Keeper, to share information and address specific issues.

 

Public Meeting #3

 

The third public meeting was held on 7 March 2006 from 6:30 p.m. to 8:30 p.m. at the Kanata Recreation Centre, 100 Walter Baker Place, Kanata.  The purpose of this meeting was to update the public on the change in the approval and review process from the Planning Act to the Class Environmental Assessment Process, the work undertaken since the last meeting; and response to public comments. 

 

Notices of the public meeting were placed in daily and weekly newspapers prior to the meeting.  The Notice appeared in the Ottawa Citizen and Le Droit on 3 March 2006 and 6 March 2006 in the local Stittsville News.  Notices were sent to adjacent landowners, community associations and attendees from the first two meetings.  The notice was also sent by e-mail to members of the public who had made inquiries to the City regarding these projects.

 

The meeting was a combination of an open house with a short presentation followed by questions from the audience.  Approximately 45 people attended and the primary comments were related to the change in process, status with agencies, post development analysis results, stormwater management and monitoring. 

 

Summary of Public Comments

 

A summary of the major issues raised by the public heard at the public meetings, from comment sheets and other submissions to the Study Team and Area Councillors are listed below with the response provided.  These issues have been incorporated and addressed in the relevant Class Environmental Assessment study.

 

  1. Will sediment be carried downstream as a result of increased flows from urban development and result in filling in the rural area?

 

Increased flows move sediment more efficiently and urbanization reduces the amount of sediment going in to the receiving system.  CH2MHill’s analysis demonstrates that the river’s flow and water levels will be minimally affected by the development, in the order of less than 2.5% increase in peak flow, and a 0.04 m maximum increase in water level downstream of Richardson Side Road.

 

The low flow velocities for existing and future conditions were modeled for the 2, 5 and 10-year storm events to assess erosion potential.  Consideration was given to the soils and bank types along the watercourse.  The banks are primarily clay and loam and the modeled velocities do not approach velocities that would create erosion for this type of bank.

 

  1. Why is filling in the floodplain being considered and how much of the floodplain is affected?

 

The City Council approved Kanata West Concept Plan and the Carp River Watershed/Subwatershed study recommended a modified floodplain for Carp River within the Kanata West development area.  The modified floodplain or two-zone recommendation was based on a holistic understanding of the form and function of the Carp River within its watershed.  Currently, the river and its floodplain are disassociated which has created an unstable river system.  The Carp River restoration project will restore the channel function while enhancing fisheries and terrestrial function of the corridor.

 

The Carp River Watershed/Subwatershed study proposed a minimum 100metre corridor to accommodate the restoration concept plan.  The Carp River corridor width that is proposed in the Class EA document varies from the existing 75 metre to intervals of 100 m, 150m, 200m, and 250 metres.  The Carp River flood plain, in many locations, is greater than 100 m and downstream (north) of Highway 417 the existing flood plain width is narrower than 100 m.  The floodplain encroachments represent approximately 28 hectares and 15% total loss of existing flood plain storage considering the reach between Richardson Side Road and Hazeldean Road.

 

The Provincial Policy Statement (PPS) and the City’s Official Plan include policies associated with a two-zone concept for floodplains.  Section 3.1.6 of the PPS describes the "tests" that must be met when defining flood fringe lands.  In eastern Ontario the Regulatory flooding hazard is the 1:100 year flood.  In the Kanata West area the flood fringe lands of the Carp River will be raised above the 1:100 year flood elevation, therefore redefining the location of the 1:100 year flood line, and infrastructure (storm sewer elevations, stormwater management pond outlets, footing elevations, etc.) will be designed considering the 1:100 year elevation in the river.  Therefore, for this situation, this represents appropriate flood proofing measures.

 

The analysis completed by CH2M Hill as part of the Class Environmental Assessment process has demonstrated that these criteria have been addressed to the satisfaction of the Mississippi Valley Conservation Authority.


 

  1. Are there flooding impacts downstream in the rural area?

 

Additional investigations and analysis was undertaken to the Village of Carp in order to assess impacts downstream of the Kanata West development.  Sixteen additional cross sections were surveyed and structure information was updated.  QUALHYMO was used to generate hydrographs and the existing conditions model was updated. 

 

The results of the post development analysis show that there is a 0.02m increase in 100 year water level downstream of Richardson Side Road and Huntmar Road, with a 0.01m increase downstream of March Road.  Upstream of Huntmar Road (east side), a 0.04m increase in 100-year water level is shown under future built out conditions.  The water level increases are not deemed significant.  The 100-year water levels at Carp Road match water levels under existing conditions.

 

  1. Will there be any flooding impacts on the Glen Cairn Community?

 

There will be no impact to upstream development as there is no hydraulic connection between Glen Cairn community and the Kanata West development.  The flooding that occurred in Glen Cairn was a result of capacity deficiencies of the local drainage systems.  At Castlefrank Road the culvert did not have sufficient capacity to convey the storm flow and resulted in flows overtopping the banks of the Carp River and flowing along Castlefrank Road.  Significant flows then entered the sewer system and resulted in sewer back-ups into basements.  A comprehensive study and analysis of the Carp River within the Glen Cairn was undertaken and recommended a major channel and culvert upgrade program that was initiated immediately. The upgrade program included culvert replacement at Terry Fox, Castlefrank, Ricky Place and Old Colony, as well as major channel reconstruction from Castlefrank through the open space to Terry Fox.  Works completed to date include the Terry Fox and Castlefrank culvert upgrades and the channel works between Castlefrank and Ricky Place.

 

  1. Concern that stormwater management is being undertaken in a piecemeal fashion.

 

The stormwater management system is being planned on a subwatershed basis following the recommendations of the Carp River Watershed/Subwatershed study.  An updated existing conditions model for the subwatershed study has been prepared.  The updated existing conditions model and post development model has been used to confirm the performance of the planned stormwater management facilities for KWDA identified in the Master Servicing Plan.  The post development model for the future build-out of Kanata West takes into account all of the planned infrastructure and restoration works associated with the KWDA as well as future development in the subwatershed area. 

 

  1. What approval agencies were consulted and what were their comments?

 

The Mississippi Valley Conservation Authority has been part of the core Study Team that has lead and guided the preparation of the Class Environmental Assessment documents.  The Department of Fisheries and Oceans has been consulted on the restoration components for the Carp River, Feedmill Creek and Poole Creek as part of the preparation of the Environmental Screening Report.  Meeting and discussions have taken place individually as well as collectively with the Ministries of Natural Resources, Environment and Transportation.  Written and verbal comments were received from MOE, MNR, MVC, MTO and DFO.  The comments received related to the technical information and analysis presented in the draft EAs focusing on the agency's areas of interest or mandate.

 

All technical and policy related comments received from the Provincial agencies have been addressed by the Study Team ( MVC, City of Ottawa Staff and the KWOG representatives and consultants).  A series of meetings took place on December 5, 2005, March 7, 2006 and March 20, 2006 to resolve comments received by the agencies.  These meetings resulted in concurrence between the Study Team and the agencies regarding their concerns.  The additional technical information and analysis agreed to by the agencies has been incorporated into the Class EAs such that the City and KWOG can proceed with completing the Class EA process.  

 

  1. Long-term assurances that the restoration plan will work.

 

The restoration work is being done following “Natural Channel Principles” which will provide a stream system that will be sustainable over the long term.  As with any system, management, and likely some maintenance will be required.  A monitoring plan and management plan will be prepared during detailed design.  Stream flow monitoring has also been recommended.

 

8.      Relocation of North South Arterial

 

There have been minor changes to the initial Concept Plan to shift the alignment of the North-South Arterial and the Main Street Extension. This is to better separate residential areas from commercial uses and to improve the connection outside of the Community to Hazeldean Road and Stittsville’s Main Street.  A report and demonstration plan for both the shift of the Main Street Extension and the North-South Arterial were been provided to the City, indicating that the objectives of the Kanata West Concept Plan are still maintained. The Kanata West Road Network Environmental Study Report by Delcan supports and justifies the proposed realignment.

 

Next Steps

 

The three Class Environmental Assessment will be finalized after City Council approval of the recommended projects for the Kanata West development area.  Notices of Completion will be published for the three Class EAs notifying the public of the availability of the reports and the 30-day public review period.  The review agencies will be sent copies of the Class EA reports for their final review.  All Schedule B and C projects identified in the Class EAs will be subject to Part II order requests to the Minister of Environment.

Appearing before Committee to give a presentation and to answer questions on the aforementioned item were Planning and Growth Management (PGM) staff members Dennis Jacobs, Director of Planning, Environment and Infrastructure Policy; Rob Phillips, Program Manager, Infrastructure Approvals; and Susan Murphy, Planner III.  Also attending to answer questions were:

§         From the Mississippi Valley Conservation Authority (MVCA), John Price, Project Engineer;

§         From CH2M Hill, Eric Emery, Hydrologist.

A copy of the PowerPoint presentation is held on file with the City Clerk.

 

In response to questions raised by Councillors, staff provided the following clarifications:

·        The 100m-corridor width referred to in the report is not a provincial policy or guideline that staff is being directed or required to use.  It is a measurement unique to this area derived through the analysis of this particular watershed, as part of the Carp River Watershed/Subwatershed Study, which established the corridor widths for the Poole Creek, Feedmill Creek and the Carp River, that being 90 metres on average.  The 100m-minimum was recommended because it was felt this would accommodate the restoration works and pathways along the Carp River system.

·        The EA demonstrates that the corridor narrows to 75m in certain areas, but this is because of existing conditions and development, not to allow for future development.

·        The title at the top of Slide 28 of the staff PowerPoint presentation should read ‘principal comments’, not ‘principle comments’.

·        Under the provincial policy statement there are several options for implementing and dealing with the regulatory flood plain, one of which is the ‘two-zone’, where flood-proofed development is allowed in the flood fringe areas.  The characteristics and topography of the Carp River flood plain permit the implementation of the two-zone and filling in the flood fringe areas, as part and parcel with the overall restoration plan.

·        There is no requirement in the provincial policy to display any type of warning on title where the flood plain will be artificially raised in order to maximize land use.  Timothy Marc, Manager, Planning and Environment Law, Legal Services advised that it could be done but added that if the requisite engineering studies have been done and it is found to be safe, one would question the necessity of such warnings.

·        The issues relating to previous flooding in Glen Cairn are not related to development in the flood plain; the problem occurred mainly due to a lack of capacity of the conveyance system (pipes).  Work is being done to improve the situation in that area.

·        A stormwater management system is being put in place on the Carp River flood plain that uses stormwater ponds, improvements to the channel, and a variety of means to ensure that the conveyance of any stormwater is managed and released in a manner that the tributaries will be able to properly convey away the water the way it would naturally.  The whole intent of the restoration project is to return the Carp River and its tributaries to the proper functioning river that it originally was.  It has been degraded over many years through a variety of circumstances but the improvements and addition of a stormwater management system through storm ponds, retention ponds and the conveyance of the water through improvements to the channel will ensure that the water that does fall through a rain event or through snow melt is properly conveyed away.  In the case of Glen Cairn, the water ended up in the community because water from a creek was flowed into a pipe that was not designed properly and did not have the capacity for it.  With the Carp River, a pipe system will not be used to convey the major flows; the natural system will be used and it will be ensured that the water gets to it in a controlled manner.  The appropriate flood proofing method, which will be used for the flood fringe area, is to raise the whole area and any development out of the floodplain.

·        Staff has taken into account the climatic conditions that can occur in storm events.  A sensitivity analysis, using varied parameters, was also conducted.

·        With respect to responsibility issues if future flooding should occur in communities in this area, Legal Counsel commented that if studies have been performed based upon the best available information, there should not be flooding.  Should it occur and claims be brought forth against the City of Ottawa, the City could point to those studies and say that, based upon the information available at the time and reasonably exercised professional judgement, that all due diligence was shown and there is no liability on the part of the City.

·        Staff is asking for approval of the projects that are being identified as preferred projects of the three Class Environmental Assessments (EAs), and after Council approval, staff will start to finalize the documentation, reflecting any matters raised through Committee and Council, and then proceed with the Notice of Completion and the 30-day public review period.  If something substantial comes out of the public review process that changes the projects identified today, it would come back to Committee and Council for information before proceeding further.

·        With respect to the 28 hectares of the flood plain that will be lost to encroachments, there is a possibility for some of the lands to go through development and subdivision as opposed to stormwater management.

·        The City of Ottawa’s contribution to the Carp River Restoration Project is approximately $1.5 million.

·        Several development scenarios were reviewed with respect to the Kanata West build-out.  One of them was complete build-out of the upper watershed based on the Official Plan, not just Kanata West, but also other areas that are developing or could be developed in future.  Through the Kanata West reach, the regulatory flood level is increasing in some cross-sections.  Areas already developed were looked at, specifically at anything over five centimetres, to ensure that the flood risk was not increased with respect to parking lots, buildings, or stormwater management ponds.  Other non-developed areas can be examined in this manner as they are developed.

·        The provincial policy statement does allow for flood-proofed development in the two-zone scenario.  The City and the Conservation Authority are taking the potential impact very seriously and they ensured a very comprehensive analysis has been completed for this specific area, looking at upstream and downstream through the reach.  Generally, development is kept out of a flood plain, especially where there is no analysis that shows the potential impacts; but in this case, the studies support development.

·        The report refers to increase in water level, not flood level.  It should be understood that when the water is flowing at its normal pace, you could increase the water level and there would still not be a flood because there is a channel to carry it.

·        One of the scenarios examined in the EA specifically addressed solely the impact of encroachment – the filling of the flood fringe.  There was a scenario that looked at full build out with no filling in the flood fringe; then full build-out with the encroachment - that scenario shows there is no increase in flood levels, meaning that the impact specifically of filling in the flood fringe is not there.  There is an increase in flood levels as development proceeds.  All numbers, as far as increases, are being compared back to existing levels as they stand today.  There was no scenario examined in terms of not changing the flood levels.

·        The majority of the works in the Glen Cairn area have been completed, although some culvert improvements may still be outstanding.  With respect to that section of the Carp River, the entire valley was filled in at the time of construction and was replaced by a pipe system, so the ability to restore that channel in an urban environment is very limited.  As a result, the solution involved the enlargement of the pipe system and the channel reconstruction.

·        The raising of water levels for the Kanata West development will not set a precedent for future developments; areas will be reviewed as and when applicable to make sure standards are adhered to, and all risks are taken into account in the planning stages.

·        During these EAs, there were a number of consultants and staff components involved that are knowledgeable about Global Warming and its effects; none of them were involved with the original Glen Cairn consultations.

·        The strategy carried forward in the Class EAs being presented is the best of the models that were examined.

·        There is a section of land upstream of Paladium Drive where water levels will rise by 18cm, and downstream of Maple Grove by 17cm, but there is no increase in flood risk for any properties situated there.  One of the models looked at lowering the channel to see if there was opportunity to make up storage within the channel configuration.  The analysis showed that, in terms of water levels at a 100-year event, there are three spots within the Kanata West Development Area where there is an increase over five centimetres: the Walter Baker Park, the area north of Maple Grove in terms of the Sensplex, and the south side of Richardson Side Road, but there are no associated property impacts or increased flood risks as this time.  With respect to liability issues, Legal Counsel advised that, based on that information, studies show no perceived threat to existing facilities and a prudent course of action would be to ensure that the specific property owners receive notice of the EA, if they have not already.

·        Staff advised that the Parks and Recreation Branch is part of the study team in terms of the Class EAs; they have not written a formal letter for the property owners but that can happen.  Staff met with Nortel, who owns a portion of the Sensplex, to inform them of the study results, but there has been no direct dialog between staff and Sensplex.  Staff will inform the rural landowner of the property near Richardson Side Road through the process as well.

·        With respect to agency approvals, staff explained that the ministries were consulted throughout the process and given draft documentation last December.  They responded in writing on 31 January, articulating the issues they felt had not been addressed in the draft documentation.  That same documentation was circulated to City staff and 189 comments were received from those sources to be dealt with.  After receiving the letter from the agencies, the consultants and the study team provided the technical analysis that was needed to satisfy those issues, and staff met with the three of them on March 7th for discussions.  The agencies felt they needed more time to review that documentation, and two follow-up meetings were planned on March 20th.  From those meetings, concurrence was reached on a number of the issues based on the technical information staff provided, and staff agreed to carry out a number of other follow-up items.  A letter followed that up from the City on March 31st with the remaining information the agencies had requested in terms of outstanding issues.  A subsequent letter went out on April 28th with the last of the documentation.  At present, the Ministry of the Environment is satisfied in terms of documentation in hand.  A letter was received yesterday from the Ministry of Transportation saying they are satisfied with the technical information provided and await the review of the Class EAs.  Staff spoke to the Ministry of Natural Resources yesterday as well, and they have just two outstanding items that they require of staff, which they will receive and all of this will be reflected in the final EA document.  Staff is presently conducting the same type of process to deal with a number of City issues raised through the process.

·        CH2M Hill conducted a number of scenarios and developed a computer model of the way the Carp River, Poole Creek, and Feedmill Creek flood plains behave under various development scenarios, existing scenarios, and ultimate development.  In late summer 2004, they installed a number of water level monitors in three locations – one immediately upstream of Richardson Side Road, one at the downstream end of Paladium Drive, and another on the upstream end of the Terry Fox stormwater pond.  In September 2004, a 12-hour rainfall occurred in the area, the results captured from that event were reviewed, and adjustments were made to the model as per those observations.

·        A team of multi-disciplinary professionals and experts in the field did the Carp River Subwatershed Study.  The Study identified a number of reaches within the Carp system that require restoration.  Today there is an opportunity with the Kanata West owners group to pursue the restoration within Kanata West, within the urban area.  The river is dysfunctional in terms of stream form and function, the aquatic habitat has been very degraded by siltation and accumulated sediment within the system, and it is very undiverse in terms of biodiversity within fisheries.  The aim of the restoration is to see an ecological benefit and have a functioning a river, both from an aquatic stream morphology point of view and as a community asset within the Kanata West development area.

·        The planning approval aspects of the three EAs have been separated out because of ongoing discussions with the Ministry of the Environment (MOE).  A process of integration is allowed between the Planning Act and the Environmental Assessment Act to link development approvals and environmental assessment approvals in the same process to ensure that the public is being consulted only once and understands how the process works, but in this case the planning approvals were for portions of the study area, not the entire study area so the MOE felt it was inappropriate to use a process of joining the planning approvals with the environmental assessment approvals because it was not taking a comprehensive look.  Staff has separated the approval processes so that the Class EAs will end up with the MOE as opposed to through the Planning Act and potentially through the Ontario Municipal Board (OMB).  That has not separated staff’s consideration or review or the public review and comment on the development, planning approval side, and the environmental assessment side but it has separated who will have the final sign-off in the EA.  The requirements to conduct the Class EAs, whether it is approved through the OMB or through the MOE, are exactly the same.

·        There are portions of the flood plain on the north side of the Jock River that do not presently, and will not have development on them, just as there are portions of the Rideau River flood plain that will not be developed.


 

The Joint Committees then heard from the following delegations:

 

Representing the Carp River Coalition, were David Spence, Amy Kempster, Carol Gudz, Erwin Dreessen, and John Almstedt.  Ms. Gudz explained that the Coalition consists of a group of Citizens that have come together out of concerns about plans to fill and develop 28 hectares of the flood plain in Kanata West along the Carp River.  The Coalition draws members from the Friends of the Carp River (David Spence), the Greenspace Alliance of Canada’s Capital (Amy Kemptster), the Ottawa Group of the Sierra Club of Canada (Carol Gudz), and the Ottawa Riverkeeper (John Almstedt).  Their goal is to ensure that development of Kanata West along the Carp River does not pose risks of flooding to upstream and downstream communities, and furthers the long-term health of the river and the various species of life it supports.  They feel that common sense dictates that floodplain development should not occur, and are challenging the City on development of this area.  They are not convinced that what they have heard through their meetings with City staff and the consultants beats the common sense test, or meets the technical requirements that are legislated.  They feel that proceeding with development may open the City to legal challenges, and note that the City does not yet have sign-off letters in hand.  Their concerns include unacceptable impacts on peak water levels and flows, unacceptable loss of flood water storage capacity, inappropriate application of policies governing flood hazards, inappropriate exclusion from the analysis of certain lands that also drain to the Carp River, long-term implications of the incremental chipping away at the flood plain, and legal precedence contradicting the plans.  They asked that Committee receive this report for information, reject the recommendations presented, and direct staff to come back when the EAs are completed (with sign-off from the provincial agencies) to request permission to post Notices of Completion.  They are surprised staff is not more forthcoming about financial implications, and suggest project approval with at least order of magnitude dollar values attached should follow after appeals of the EA approvals have been concluded.  They question the City’s liability as an adjacent landowner.  They question whether development charges revenue will cover the cost of all projects except those mentioned – stormwater ponds and trunk storm sewers.  They question whether there is not a benefit to existing that the City would have to contribute to some of these projects.

 

John Almstedt stated that the Ottawa Riverkeeper supports the restoration project but he has some concerns.  He was pleased that many of the concerns he has raised with staff in past were being addressed at the Committee level today.  He was amazed that a 725‑hectare project could be held because of concerns over what will happen to the 28 hectares.  He noted upstream and downstream landowners have voiced various concerns about narrowing the flood plain from 500m to 100m.  He suggested staff is taking an unusual approach to dealing with hazard land, noting there is no other CA in Ontario that has a record of doing what is being proposed here.  He questioned the 15% reduction in storage and the 18cm increase in flood levels when the City has already spent hundreds of thousands of dollars in a watershed plan and on EA plans.  He felt that perhaps the workings of a flood plain and a healthy ecological system are not fully understood.  He also felt many questions need to be answered more clearly, such as what will happen when future development occurs.  He felt that some past staff comments are contrary to what is being presented today.  He questioned why it is being said now that 28 hectares will be lost to encroachments when it was originally reported to be 60.  He thought perhaps the original number included the stormwater ponds and those have been taken out of the calculations now.  He questioned whether the impacts are acceptable to upstream and downstream owners, and suggested that might not be the case.  He felt it sets a dangerous precedent for the future to allow some flood plain development now, especially without developing a very coherent management strategy.  He questioned the approval of the Mississippi Valley Conservation Authority with respect to the development in this area, and suggested their opinion would not be the same if it involved their own lands.

 

Amy Kempster referred to the two-zone flood plain policy, noting the suggestion to divide the flood plain into two parts – one part not to be developed, and the other they refer to as the fringe.  Her understanding in reading the provincial guidelines on natural hazards is that this approach is supposed to be limited to those areas that are essential to the continued viability of existing uses, in other words, historical sites or old neighborhoods built before flood plain policies came into effect.  She did not feel the approach was intended for green field situations, and she felt it undesirable to build in a flood plain where it might create problems and dangerous situations .  She suggested that the conditions for applying the two-zone flood plains have not been met.  She noted they have been shown increases in flood levels in some reaches of the Carp River up to 18 cm, and increases in peak flow rates in some areas of almost 42%.  The size of these increases would constitute an aggravation of an existing hazard, if not the creation of a new hazard.  She questioned any assertion that such increases in peak flow rates would have no negative environmental impacts, therefore the conditions for a two-zone flood plain policy set out in the provincial guidelines have not been met.  She said that they were told the proposal to apply a two-zone flood plain would have to be decided by the OMB, when that policy comes forward, it could be appealed to the OMB.  She pointed out that the Joint Committees are being asked to approve projects that depend on the use of the two-zone flood plain, and the Joint Committees should not be doing this until other steps have been taken.  She stated the whole thing has to be deferred until the EA process is done, and until the two-zone flood plain has been brought forward to Committee.  She feels things are being done backwards.  She also feels the suggestion that the final decision be delegated to staff would be an abdication of responsibility and she does not think the Joint Committees should accept that kind of suggestion from staff.

 

David Spence, spoke on the Carp River as a municipal drain.  He said that contrary to the position of the City, there is more than sufficient documentary evidence to support that the Carp River is a municipal drain under the Drainage Act.  By-laws have been passed and engineering drawings have been made showing the configuration of the drain adopted in the by-law.  The municipality, or its successors, is responsible for keeping copies of the by-laws.  The onus is on the City to locate the Engineer’s Report and establish the original record of landowners in the area requiring drainage to determine if they are in support of the proposed alterations to the municipal drain, or records showing that the drain has been abandoned through a by-law.  If the City remains uncertain about its position, it could turn to the referee under the Drainage Act for a determination.  He expects the referee, an Ontario Supreme Court judge, will not hear the case because the conclusion is overwhelmingly evident.  He submits that, by modifying the profile of the main channel of the Carp River, the City and the developers may be subject to legal challenges from downstream landowners.  As well, the Ontario Court of Appeal has confirmed the sufficient outlet for this drain is below the Village of Carp.  He pointed out that they have been talking about the movement of sediment, of water all stopping at Richardson Side Road, because that is the extent of the restoration being discussed.  He noted that in 1910, it was determined that the sufficient outlet for any drainage happening upstream of the Village of Carp had to come to the sufficient outlet below the Village, and feels this cannot have changed in that period of time.  He feels that is something the Joint Committee has to take regard to.

 

He also spoke on the inappropriate exclusion of other urban lands from EAs.  He questioned the exclusion of the Del/Brookfield lands from the EAs for Kanata West.  Even a consultant working for the Kanata West Landowners’ Group has been on record as commenting that a review of the CRWSS would be required if the Del/Brookfield lands were brought in to the urban boundary.  Now that the urban boundary has been expanded to include Del/Brookfield, insofar as these two development areas both drain to the Carp River, must be included in the full build-out scenario.  He submits that the exclusion of the Del/Brookfield lands from the EA is an important flaw, and that the suggestion that somehow the urbanization of the Del/Brookfield lands will have to be made to have zero impact on flood levels is not credible, and borders on responsible.  He expressed concern about the cumulative impact of all this development from a quality standpoint, none of which can militate against the salt, materials in suspension coming off their properties, pesticides, herbicides, and things that come from automobiles.  He sees insufficient amounts of mitigation built into this proposal and would like to see that, rather than filling in the flood plain, its use should be maximized.  He thinks the best possible use for the most number of people is to maximize the flood plain a constructive wetland.  This would enable bio-remediation of many of the materials coming downstream from this very built-up community and preventing it from getting into the Ottawa River.  This is a major tributary to the Ottawa River upstream from the filtration plant, and the more material in suspension coming down the river will affect downstream communities, including the City of Ottawa and the people using that source of water.  He feels that with the proposed development in Kanata West, we are putting a virtual city at the headwaters of a river with virtually next to nothing in terms of development downstream, and we are going to see a reversal, very foul water coming down and heading towards the Ottawa River, which is a big concern to all.

 

Erwin Dreessen concluded the Coalition’s presentation by reiterating that this development in the Carp River flood plain is a high-risk undertaking for the City and the taxpayers with potential liability, not to mention health and safety issues related to flooding.  He referred to the Deputy City Manager’s comments last week on how we are not ready to address challenges of climate change in Ottawa, and noted that next week, there will be a National Conference of professional engineers on climate change in Ottawa, on engineering infrastructure, with three so-called “hundred year events” having occurred in the last three years.  He thinks there is little doubt in the mind of the average person that moving ahead with development in the flood plain would be a move in the wrong direction.  The Coalition believes the development should either stay out of the flood plain entirely, or be supported by a clear demonstration that all the conditions surrounding this type of development are being met.  The Coalition, having spent collectively thousands of hours assimilating available information, is not convinced the conditions have been met.  He stated that prior to amalgamation, the Region did not allow the application of a two-zone flood plain policy, except for existing lots.  He cautioned the Joint Committees of being asked to approve infrastructure projects on this high-risk undertaking and to approve these projects before the EA has been completed.  The Coalition submits that public interest will not be at all well served if these projects are being approved unconditionally before the assessments are complete.  The Coalition believes, based on the information they have seen to-date, that the research that has been done in these EAs does not support the go-ahead to these developments at this time.  On behalf of the Coalition, he proposed a motion for deferral of approval of the infrastructure projects until the EAs are complete.

 

Chair Hume summarized the concern of the Coalition to be against development in the flood plain due to unresolved issues.

 

In response to Councillor Cullen’s question on the municipal drain issue, Mr. Spence advised that there are records and maps going back to 1910 when it was created as a municipal drain.  The fact that no one has been able to produce any documents to refute that, or producing a by-law to that effect, he feels that it is not up to a citizens’ group to do that research.  He also advised that the City has been active in the last week trying to do the research at the Carp Library.  There are newspaper accounts of the time documenting it, and they have not been able to find an engineer’s report.  He stated that the area from Hazeldean down to the Village of Carp was dredged and straightened, to enable farmers to get on their lands earlier, everyone that was perceived to have benefited from that drainage construction had to pay into it.

 

Dave Ryan, Drainage Superintendent remarked that the by-law for the drain gives a drain legal status under the Drainage Act.  Staff has not located the by-law from the former March Township, the initiating municipality, indicating that the drain has legal status.  There are plans, profiles, and there is documentation to suggest it was a municipal drain back then.  He has consulted with Ontario Ministry of Agriculture and Food (OMAF) and the legal status of the drain is questionable.  There are no records from the former townships to indicate that any work was ever done in the last 100 years to maintain the watercourse.  In light of all the documentation, he suggested the improvements were undertaken in 1910, and the inability to locate the by-law does not mean it does not exist.  He recommended that the documentation be reviewed by the City’s Legal Department, to determine the status of the river with respect to the Act, and if it is determined that it does have status, the City could undertake to repair and maintain the drain and the costs would be assessed to the benefiting landowners.  He noted this decision could be appealed to the Ontario Drainage Referee, who would determine whether it has status under the Act.  Mr. Ryan further advised that a drain could not be changed without the report of an Engineer appointed by Council under the Drainage Act.

 

Mr. Jacobs informed the Joint Committees that the strategic differences between a Class EA process and a restoration through a Drainage Act petition depends on who approves it because the type of work and activity are the same.  One of the disadvantages for the property owners is that, should there be restoration and work, the costs would be assessed against all the abutting landowners.  Under the current process, the cost would be assessed against the Kanata West Development area, plus a portion to the City.

 

Mr. Marc noted that in the agenda there are separate recommendations for the concurrence of the EAs and the projects.  To hold on to these projects pending the outcome of the EAs is an option opened to Council, and is within the purview of Council to do so.

 

In response to Councillor Legendre’s question on process, Mr. Jacobs clarified that the purpose of staff coming forward with this report is to make the Joint Committee aware of the work that has been done and the projects that have been identified before going through the legislated steps of a Class EA process.  Mr. Jacobs noted that any time staff is in front of the Committee with a recommendation, the Committee can provide additional direction; modify recommendations, and / or take other action.  An action recommendation could be to refer the report back to staff for further work to be done.  A motion to simply receive the EAs is different and would not move this matter forward at all.

 

In response to Councillor Stavinga’s question on the appropriateness of one of the delegation’s comment for not receiving sign-off from other agencies, Ms. Murphy advised that staff is not looking for a letter of concurrence at this stage in terms of the EAs because they are still to be finalized.  Staff is looking for a verbal or a written letter from the agencies stating that they have all the required technical information and are comfortable with the City moving forward to the notice of completion.  She also advised that a letter was received from MTO, which she read.  With respect to concurrence request, the letter states that the agencies have not seen the final draft EA document.  It cannot concur with document they have not seen but in principle agreed to move forward.  The concurrence letter will come through the 30-day review period when receiving the completed package and after having seen all the information provided to them is in a comprehensive package.

 

Mr. Jacobs concurred with Councillor Stavinga’s clarification that the agencies could not sign-off at this stage and that staff could have applied the same process as for the Carp River Restoration, which was to make sure that everything is bound like this, bring it to Committee and Council and then do the notice of completion.  However, it is her understanding that in doing so there were concerns that it was done in a too complete approach. 

 

In response to Councillor Bloess’ questions, Mr. Almstedt advised that he would like to see some concrete data to review.  As Riverkeeper, he sees himself as helping to make better decisions in the community based on science, not on emotion.  Consequently, Councillor Bloess felt that if information being generated is not made available, there should be direction from the Committee for it to be provided to the community.

 

With respect to Councillor Bloess’ question on the municipal drain issue, Mr. Dreessen stated that the Coalition firmly believes there is sufficient documentary evidence and it was confirmed that at one point a drainage project was implemented.  The Coalition finds it quite frustrating that staff continues to deny that it was clearly a drain.  He said that documentary proof lies very clearly with the City and it has to produce a by-law stating that the drain has been abandoned.  The Coalition is quite firm in saying, unless that is produced, it remains a drain and nothing can be changed about that.

Mr. Ryan confirmed that a by-law indicating that this actual drainage work was approved by the Township of March Council of the time could not be found.  However, there is other supporting documentation and it would be a legal decision for the drainage referee to make that determination.

 

In reply to Councillor Doucet’s question on the matter of two-zone, Ms. Kempster advised that she is not an expert on that but as she understands it, the flood flow plain is where the water goes quite quickly, the fringe is outside of the main flow of the river during the flood.

 

In response to questions raised by Councillors, staff provided the following clarifications:

·        The implementation of a two-zone floodplain approach is a matter under the Planning Act and to do so requires a zoning amendment, which would be under a separate process.  The work that is being proposed through the restoration and through the EA works in front of Committee assumes that approval could be achieved - one builds on the other.  Staff estimates having the by-law here today would be prejudging Council’s decisions and the decisions on the EAs.  The EA approvals are required before commencing that process.

·        The rezoning process has never been a rubber-stamping process regardless of what kind of work has gone on in advance; it is a decision made by this Committee and Council.  Information that would support a rezoning application to implement a two-zone concept would be based on the work that has been done to date.  There would not be additional modeling work or additional work about the floodplain to support that by-law.  It would be an action item coming out of the approval of the EA process; to change the zoning by-law is in the purview of this Council and should Council decide not to, it would be its prerogative.

·        Should Council not approve the two-zone concept, or even approve this concept but was appealed to the Ontario Municipal Board (OMB), staff would have to come back to Committee and Council for an addendum to the EA to address the issue.

·        If the subject watercourse were a municipal drain, it would completely be exempt from the EA process – so all the work that staff had gone through would not have been necessary.  There would be no opportunity for a bump up request from outside organizations.  The only person that could express an appeal would be the landowner, and so the entire public process that had gone through and continue to go through would be completely unnecessary by law.

·        Staff had taken the appropriate approach because given the very truncated process associated with matters under the Drainage Act one should only take that approach if it is absolutely clear that in fact it is what it is.  In the absence of a by-law, it would have been completely inappropriate for staff to have taken that approach and rather staff has taken one on the basis that exemption does not apply; that it is subject to the EA process; and the necessary report come before Committee and Council.

·        All municipal drains, whether they are exempt from the EA process or not, require the conservation authority approval, and engineers do have guidelines to follow with respect to environmental aspects.

·        With respect to municipal drain and stream restoration, the engineering report governs the work that can operate within the drain.

·        Staff is going beyond the engineering scheme and is looking at conveyance in a more natural channelled design principle, as well as looking at a full restoration in terms of aquatic and habitat.

·        Under the Conservation Authority Act, all conservation authorities in the province have regulations that apply to filling floodplain and construction on floodplain.  If staff feels that a permit is beyond policy and wants to actually recommend denial, then it has to go to a hearing locally at the Conservation Authority Board.  There is a sub-set of hearing board, the only place a permit can be formally denied with given reasons.  If an applicant in the CAA is appealed and third party input is just between the CAA and the applicant, there is no third party appeal process.  Therefore, if an applicant is unhappy with the decision of the denial then the next stage is to go to the Lying Land Commissioner, who will hear the appeal of the applicant.

·        Like the Rideau Valley Conservation Authority, the Mississippi Valley Conservation Authority had local hearings and denials, but never had a denial appealed to the Lying Land Commissioner, which indicates that applicants have either accepted the denial and/or changed their application to bring it to conformity.

·        The agreement with the landowners is that the majority of costs associated with the identified projects will be borne by the Kanata West Owners Group.  They will be installing all the sanitary and storm sewers as an addition to the stormwater management pond, completely at their costs on a shared basis.

·        The nature of the Official Plan Amendment (OPA) being presented with the establishment of the Kanata West Owners Group was the caveat to move forward with regard to establishing that payment mechanism.  Therefore, as it stands to date, there is a list of projects that have been provided, some of which are already identified inside the City of Ottawa’s Development Charge By-law; some of which would be completely borne by the developers as they proceed.

·        The EAs were done in cooperation with the landowners.  The City is a co-proponent and a co-applicant.

·        The City is not the approval authority.  The EAs are filed with the Ministry and if there are no bump-up requests, then it is deemed to be approved, but if anyone were to be considered the approval authority, it would be the Ministry of Environment.  Council is hopefully directing the filing of the environmental assessments.

 

Don Kennedy, Project Manager, Kanata West Owners' Group Inc. gave a brief history about the Group and its purpose.  He advised that studies for this project are not part of the development charge and yet every owner will benefit from not only part of the EAs that are being dealt with but other projects within the area.  There are currently 16 owners participating, covering approximately 80% of the geographical area.  Every owner will be given the opportunity to join the group and until the owners’ land goes under development, there will be no particular assessment against them.  The Owners’ Group felt that it was very important from the study perspective to get into a development agreement to pay for a very significant amount of study work.  The restoration project is not part of development charges; all the local sewers and lot of the major trunk sewers, watermains, and stormwater management ponds are not development charged items.  The 189 comments from the City and 30 comments from the three provincial agencies originally received for the first drafted EAs have now been whittled down to being at the final stroke.  He noted that the Ministry of Fisheries, together with the Ministry of Environment, the Ministry of Natural Resources and the Ministry of Transportation were involved in this project.  He then spoke on the funding of the restoration project and stated that the broad term ‘70% landowners, 30% City’ put forward warrants a little bit of breakdown.  The 28 hectares of encroachment into the floodplain would be a huge part of the funding of the restoration plan.  Completed existing development, the building of Hazeldean Road and Terry Fox Drive have an impact on the floodplain.  Consequently, 30% of the restoration cost was assigned to the City; 45% was assigned to adjacent owners; and 25% was assigned to the overall Kanata West Community.  In order to clarify Councillor Legendre’s question on the 100 m-minimum corridors, he believes that the Councillor is reading this in relation to Poole Creek – 90 m.  He noted that the Subwatershed Study actually has different corridor widths for Poole Creek and Feedmill Creek than it does for the Carp River, and those are in the approved Subwatershed Study.  He spoke on the process and thinks that it is appropriate for the Committee to recommend approval of the staff report to Council in order to allow the filing of the notices of completion.  He feels that it is very important to get the notices of completion out so the Ministries can respond.  The Ministry of Transportation has agreed and indicated that the City is committed to make sure that the Dell/Brookfield Lands are properly looked after and they have acknowledged its acceptance, and wanted to be involved in the community design and environmental management process.  The Ministry is also satisfied that Kanata West under itself increases the water level separation between current levels and the bridge on the 416.  In order to sign off the Ministry needs to get these EAs into their hands and into the communities’ hands so that any issue raised in that 30-day appeal period can then be addressed.  He advised that issues raised by the Coalition with respect to the restoration project were discussed by at least three hydrologists, who had been working on this project and also with the Mississippi Valley Conservation Authority signing off on the modelling and putting this forward.  The Group is very convinced and comfortable that all of these projects can move forward.  On behalf of the owners, he urged the Committee to endorse the staff report so that this project could move on to the next step.

 

In response to questions raised by Councillors, the following clarifications were provided by the delegation and by staff:

·        The whole restoration project replaces floodplain storage by improving the Carp River through this particular reach.

·        The improvement of the water flow in the Carp River, in the reach of Kanata West, is necessary to get it away from being a degraded stream.

·        For technical reasons to do this encroachment, the entire area was studied; a new low flow channel created, replacement of volume storage, and the comment of 15% lost of riparian storage is incorrect – it is only one percent.  So all of these things created by encroachment allow for floodplain storage and an active stream with greater flows, moving sediments through it and a much better river environment.

·        The largest portion of the flood plain belongs to West Kanata Developments, Richcraft and Capital Sports.

·        Because there is a benefit through all the pathways going through the areas, 25% of the cost is spread over every Kanata West land owners; 45% would go to the adjacent Carp River owners; and the 30% is a benefit to existing.  In that 70%, a third of it will cover the entire area, so everybody has to pay a piece of the enhancement because it is a benefit to the community as well as to the River, and those adjacent get another 45% of the total tack added on because of location.

·        Information was provided to the Provincial agencies and the Coalition in significant volume.  There were meetings with all the agencies and the Coalition to go through the information.  The agencies were satisfied with the information provided and directed to file them.  Any further information would be made available to all.

·        The 100-metre reference was a proposal that came out of the earlier work and has been refined with more detailed work under the class environmental assessment process.  The 75-metre pinched point is based on an existing development that was approved through the City.  The other areas where the corridor widens out reflect circumstances that through the more detailed analysis that 100 metres were not sufficient, so they went wider where possible.  There is some fill being proposed in the flood fringe; the 100 metres or more is still being maintained and that is not encroaching into that area.

·        During the review process, the encroachment of 28 hectares, 15% is the portion of the floodplain that is lost to encroachment outside the 100-metre corridor.

·        The Ministry of Natural Resources asked to look at the riparian storage, in other words within the system where there are water edge requirements, to determine what would happen.  That loss was originally 6% and by refinements and modelling it got down to 1%, which is well within the tolerance limits of the model and there is virtually no loss of riparian storage.

·        The Restoration Plan serves many purposes – some of which are fisheries enhancements, some terrestrial enhancements, and some drainage enhancements; as well as to have enough functioning floodplain.

·        We have now a floodplain that, in times of higher flows when the river needs to use the floodplain, the water cannot readily get back into the main channel when the flood is being conveyed downstream as it needs to be.  The Restoration Plan redefines a low flow channel that functions from the standpoint of moving sediments and lower flows to not create cool and stagnant water.

·        There is grading in the floodplain lands to allow positive drainage for those infrequent events when you get water in the floodplain and back in.

·        The Restoration Plan is important for all aspects of the Carp River.  It has been described certainly from a funding standpoint that the encroachment is important but also to result in a functioning river system.
